Description

Note: Descriptions are shown in the official language in which they were submitted.


Faucet Assembly
The present invention relates to a water faucet, and more particularly to a faucet
assembly which is designed with structures permitting an easy and fast assembly and
replacement.
It is a well known fact that it is messy and troublesome to repair or replace a
worn out water faucet of the conventional type described above. The conventionalwater faucet with the threaded conduit is prone to bringing about a water leakage
because the engagement of the threaded conduits is vulnerable to becoming loose after
a prolonged usage. Furthermore, it is tedious and inconvenient to have the
conventional water faucet, replaced, the reason being that the water faucet can be
detached from the wall water conduit only by means of using a wrench to rotate ahexagonal nut which is securely fastened to the former. As a result, consumers at large
often have to resort to a professional plumber for a repair job as and as such and are
thus subjected to a great expense.
The primary object of the present invention is to provide a faucet assembly withstructures permitting an easy and speedy assembly and replacement.
Another object of the present invention is to provide a faucet assembly that
prevents the uncontrolled egress of water from a water outlet pipe.

Description of the Drawings
Fig. 1 is a perspective view of a faucet structure of the prior art.
Fig. 2 is a partially exploded view of an embodiment of the faucet structure which
conveys the concept of the present invention.
Fig. 3 is a cross-sectional view of the assembled embodiment of the faucet structure of
Fig. 2.
Fig. 4 is a schematic, cross-sectional view of the check valve function of the above
embodiment.
Referring to Fig. 1, a conventional water faucet comprises a main body 1 which
has a rotatable water tap 2 hinged thereto by means of a screw 200. Located behind
the water tap 2 is a hexagonal nut 3 to be rotated by a wrench, the externally threaded
conduit 5 to be set securely into the internally threaded conduit embedded in a wall.
A ring 4 with an arc surface is disposed in front of the threaded conduit 5 for the
purpose of putting the abutment out of sight. The front end of the main body 1
constitutes a water outlet 100.
Referring to Figs. 2 and 3, a faucet assembly primarily comprises a faucet 10,
an inner sleeve 20, a washer 30, a middle sleeve 40, an outer sleeve 90, an O-ring 80
in the middle sleeve 40, and a valve gate 50 in the inner sleeve 20.
A knob 11 is disposed on the top of the faucet 10, and a protrusion 12 is
disposed on the rear portion of the faucet 10 upwardly. A plurality of threads 13 are
formed on the rear portion of the faucet 10. Thus the protrusion 12 is disposed
between the knob 11 and the threads 13. The inner sleeve 20 tapers from the rearportion to the front portion. Three arc shaped protrusions 21 are disposed on the outer
periphery of the inner sleeve 20. Three recesses 24 separate the arc protrusions 21
respectively. An outer flange 22 is disposed on the outer surface of each recess 24
respectively. An inner flange 22 is disposed on the inner surface of each recess 24
.~
:,~

respectively. Therefore, the protrusion 12 is positioned by one of the three recesses
24. The front portion of each arc protrusion 21 has a groove 25. The inner pipe 70
which passes through the wall connects with an outer pipe 70 which is in the wall. The
middle sleeve 40 tapers from the rear portion to the front portion. An inner stoppage
flange 41 is disposed on the inner surface of the middle sleeve 40. The middle sleeve
40 encloses the inner sleeve 20. The front portion of the washer 30 is inserted in the
rear portion of the inner sleeve 20.
The valve gate 50 has a cone 51, four supports 52, and a stoppage ring 53. The
stoppage ring 53 is in the front portion of the valve gate 50, and the cone 51 is in the
rear portion of the valve gate 50. The valve gate 50 has a hollow interior to allow water
to flow through it.
Referring to Fig. 3, the outer pipe 60 is embedded in the wall. The outer pipe 60
has inner threads to match the outer threads of the inner pipe 70. The valve gate 50,
the O-ring 80, the washer 30, and the outer sleeve 90 are inserted into the inner pipe
70. Thus the valve gate 50 is confined by the O-ring 80 and the threaded washer 30.
The middle sleeve 40 encloses the inner sleeve 20, and the outer sleeve 90 encloses
the middle sleeve 40. Before the faucet 10 is inserted in the inner sleeve, the cone 51
will be pushed forwardly by the water pressure so that the cone 51 will be adjacent to
the O-ring 80. Thus the water flow is stopped.
Referring to Fig. 4. the faucet 10 is inserted into the inner sleeve 20. Thus the
middle sleeve 40 will move rearwardly. The inner stoppage flange 41 will move to the
front portion of the inner sleeve 20. The arc protrusions 21 will flare outwardly so that
the rear portion of the faucet 10 can be easily inserted in the inner sleeve 20. The inner
flange 22 will intermesh with the threads 13 in order to position the faucet 10 securely.
Then the middle sleeve 40 will be moved to the outer flange 23. Thus the outer flange
23 can confine the rearward motion of the middle sleeve 40. The protrusion 12 and the
recesses 24 can intermesh with each other so that the faucet 10 will not be rotated or
loosened. Then one end of the outer sleeve 90 covers the rear portion of the faucet 10,
and the other end of the outer sleeve 90 is adjacent to the wall.
When the middle sleeve is moved rearwardly, the arc protrusions 21 will be flared
outwardly. Therefore, the faucet 10 can be easily disassembled. When the faucet 10
.: ~

is separated from the inner sleeve 20, the valve gate 50 is pushed forwardly by the
water pressure. Thus the water flow is stopped.
