ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a lavatory faucet, and more particularly to a locating structure of the water mixing bolt of the lavatory faucet.
2. Description of Related Art
As shown in
FIG. 1
, a prior art lavatory faucet
20
is located on a lavatory basin
16
such that the lavatory faucet
20
is fastened with the lug
22
of a connection pipe
13
by two fastening bolts
21
. The connection pipe
13
is located between a cold water valve
10
and a hot water valve
11
, which are respectively connected with a cold water pipe
14
and a hot water pipe
15
. The cold water pipe
14
and the hot water pipe
15
are received respectively in a mounting hole
17
of the lavatory basin
16
in conjunction with a locating board
18
and a locating ring
19
. Located between the lavatory basin
16
and the lavatory faucet
20
is a cover board
23
. The prior art lavatory faucet
20
described above is defective in design in that both locating board
18
and the locking rings
19
are located at the underside of the lavatory basin
16
and are therefore difficult to be reached by hand or hand tool. As a result, the locking rings
19
can not be easily unfastened to disassemble the water valves
10
and
11
, as well as the lavatory faucet
20
. In other words, the work of replacing the lavatory faucet
20
is time-consuming at best.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a lavatory faucet which is free from the deficiency of the prior art lavatory faucet described above.
The objective of the present invention is attained by a lavatory faucet comprising a connection pipe, a fixation board, a water mixing bolt tube, a locating bolt, and a faucet neck. The water mixing bolt tube is located securely by the connection pipe and the fixation board, which e disposed between two water control valves. The faucet neck is secured to the water mixing bolt tube in conjunction with the locating bolt which is engaged with a threaded hole of the faucet neck via a through hole of a lug of the connection pipe.
The features, functions, and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
