52 is rotated to move inwardly inside the second sleeve 51, so as to make the
first
locking member 52 push the first abutting blocks 53 moving towards the first
hole 511
along the inner wall of the tapered structure in the second sleeve 51
synchronously. The
distance between the first abutting blocks 53 is correspondingly reduced so
that the rope
3000 is clamped tightly and connected to the first clamping member 50. When
the rope
3000 is separated from the first clamping member 50, the first locking member
52 is
rotated to move out of the second sleeve 51, so as to reduce thrust from the
first locking
member 52 to the first abutting blocks 53 until the thrust disappears, and
clamping forces
between the first abutting blocks 53 and the rope 3000 disappear gradually,
thereby the
rope 3000 is separated from the first clamping member 50, so as to realize
fast
11
50767-004
Date Recue/Date Received 2020-05-26

connection and separation between the rope 3000 and the first clamping member
50,
and make its use be more convenient.
[0037] In an embodiment of the disclosure, the first locking member 52

abuts against the first abutting block 53.
[0041] The second elastic part 522 can be a spring. The locking block 521 can
be
connected or fixed to the movable rod 30 through a thread structure. A side
face of the
locking block 521 connecting to an end of the movable rod 30 can be of a
hexagon
structure or a similar structure, so as to clamp on the locking block 521 and
rotate it by
an external wrench to realize rotation adjustment of the locking block 521,
and make its
use be more convenient.

Date Recue/Date Received 2020-05-26

rod 30. The second locking member 54 is located at the end of the first
locking member
52 away from the second sleeve 51.
[0043] The second locking member 54 can be a nut. The second locking member 54
is
rotated to closely abut against a corresponding position of the first locking
member 52,
so as to avoid looseness of the first locking member 52, and make connection
between

of the rope 3000 is connected to the rope connector 1000 or two ends of the
rope 3000
are respectively connected to the two rope connectors 1000. The rope
connector(s)
1000 is/are the aforementioned rope connector 1000. The rope 3000 can be a
steel wire
rope. The rope assembly 2000 is more convenient for use. After the rope 3000
is
tensioned, a force in axial direction which the rope 3000 is subjected to is
an elastic force,
which is smaller than a rigid locking force, so that an axial load which the
rope 3000 is
subjected to is smaller relatively, so as to increase service life of the rope
3000. Since
the aforementioned rope connector 1000 is applied in the rope assembly 2000,
the rope
assembly 2000 also is of all the beneficial effects brought by the rope
connector 1000 in
the embodiments above, and there no more details here.
[0045] Referring to Fig. 1, Fig. 2 and Fig. 4, the disclosure further provides
a rope
assembly 2000 which includes a rope 3000, a rope connector 1000 and a rope
connection component 4000. Two ends of the rope 3000 are respectively
connected to
the rope connector 1000 and the rope connection component 4000. The rope
connector
13
50767-004
Date Recue/Date Received 2020-05-26

1000 is the rope connector 1000 mentioned above. The rope connection component
4000 includes a second connecting part 70, an adjusting rod 80 and a second
clamping
member 90.
[0046] An end of the second connecting part 70 is disposed with a third
connecting
portion 100, another end of the second connecting part 70 is provided with a
fourth
connecting portion 110, an end of the fourth connecting portion 110 is formed
with a
holding groove 111.
[0047] An end of the adjusting rod 80 is disposed inside the holding groove
111, the
adjusting rod 80 is screw-connected to an inner wall of the holding groove
111.
[0048] The second clamping member 90 is disposed on another end of the
adjusting rod
80 away from the second connecting part 70.
[0049] In conjunction with the rope connector 1000, the adjusting rod 80 is
configured to
adjust tension of the rope 3000. The rope connector 1000 and the rope
connection
component 4000 are installed and fixed firstly, then two ends of the rope 3000
are
respectively connected to the rope connector 1000 and the rope connection
component
4000, and finally the tension of the rope 3000 is adjusted through the
adjusting rod 80, so
that the rope assembly 2000 can be assembled and installed more convenient and
fast,
which make its use be more convenient. Due to the installation method of hard
tension of
bolts to the two ends of a rope assembly in prior art, during installation
process of the
rope assemblies, 9 rows of rope assemblies are generally installed, the middle
row of
rope assembly is installed firstly, and then 8 rows of rope assemblies which
are upper
and lower than the middle row of rope assembly are installed in sequence.
During the
14
50767-004
Date Recue/Date Received 2020-05-26

installation process, bolts at two ends of each row of rope assembly are pre-
locked firstly,
and then their tightness of each bolt is adjusted as a whole, so as to make
tension states
of 9 rows of rope assemblies be consistent. The rope assemblies often need to
be
adjusted many times, which is very troublesome. However, for the rope assembly
of the
disclosure, only the rope connection component 4000 of each row of rope
assembly
needs to be adjusted so as to achieve the same tension state of the rope 3000,
without
the adjustment of both ends of the rope assembly, which can greatly improve
installation
efficiency of the rope assembly 2000. In addition, after the rope 3000 is
tensioned, a
force in axial direction is an elastic force, which is smaller than a rigid
locking force, so
that a radial load which the rope 3000 bears is smaller relatively, so as to
extend service
life of the rope 3000. Since the aforementioned rope connector 1000 is
applied, the rope
assembly 2000 also has all the beneficial effects brought by the embodiment of
the rope
connector 1000, and there no more details here.
[0050] Further, in an embodiment of the disclosure, the second clamping member
90
includes a third sleeve 91, a second sliding block 92, a third elastic member

hole 911 and
a fourth hole 912 communicating with an interior of the third sleeve 91. An
inner wall of
the third sleeve 91 close to the third hole 911 is of a tapered structure. A
transversal
cross-section area of the inner wall of the end of the third sleeve 91 close
to the third
hole 911 is smaller than that of an inner wall of another end of the third
sleeve 91 close to
the fourth hole 912.
50767-004
Date Recue/Date Received 2020-05-26

[0052] The second abutting blocks 94 are movably placed inside the third
sleeve 91, the
second abutting blocks 94 are arranged in a ring-shaped and spaced from each
other,
first ends of the second abutting blocks 94 are disposed close to the third
hole 911, and
the rope 3000 passes through the third hole 911 and is disposed between the
second

member 93 abuts against the second abutting blocks 94.
[0055] The second abutting blocks 94 move towards the third hole 911 along the
inner
wall of the tapered structure in the third sleeve 91 synchronously when the
adjusting rod
80 gradually moves inwardly inside the third sleeve 91, and thereby a distance
between
the second abutting blocks 94 is correspondingly reduced.
[0056] The third sleeve 91 can be made of metal or plastic. When an end of the
rope
3000 passes through the third hole 911 and is disposed between the second
abutting
blocks 94, the adjusting rod 80 is rotated to move inwardly inside the third
sleeve 91, so
as to make the adjusting rod 80 push the second abutting blocks 94 moving
towards the
16
50767-004
Date Recue/Date Received 2020-05-26

third hole 911 along the inner wall of the tapered structure in the third
sleeve 91
synchronously. The distance between the second abutting blocks 94 is
correspondingly
reduced so that the rope 3000 is clamped and connected to the second clamping
member 90. When the rope 3000 is separated from the second clamping member 90,
the adjusting rod 80 is rotated to move out of the third sleeve 91, so as to
reduce thrust
from the adjusting rod 80 against the second abutting blocks 94 until the
thrust
disappears. The clamping forces between the second abutting blocks 94 and the
rope
3000 also disappear gradually. The rope 3000 can be separated from the second
clamping member 90, so as to realize that fast connection and separation

abuts
against an end of another connecting part 70.
[0058] The third locking member 95 can be a nut. The third locking member 95
closely
abuts against a corresponding position of the second connecting part 70, which
avoids
looseness between the adjusting rod 80 and the fourth connecting portion 110
and
makes connection between the second clamping member 90 and the rope 3000 be
more
stable.
[0059] Referring to Fig. 1, Fig. 3 and Fig. 5, in an embodiment of the
disclosure, the first

member 56
is rotated to move out of the fourth sleeve 55, so as to reduce thrust from
the fourth
locking member 56 to the clamping claw 57 until the thrust disappears. The
clamping
forces between the holding pieces 571 of the clamping claw 57 and the rope
3000 also
disappear gradually, thereby the rope 3000 is separated from the first
clamping member
50, so as to realize fast connection and separation of the rope 3000 and the
first
clamping member 50, and make its use be more convenient.
[0065] An end of the fourth locking member 56 of the second clamping member 90
