Second, the inner body 30 and the inner water outlet pipe 60 can be integrally molded with plastic materials, so as to avoid the situation where lead is easily precipitated during the water supply process and lead to lead pollution in the water source, which is traditionally made of metal materials such as copper or zinc alloy. Therefore, the health hazards to the human body can be effectively avoided, thereby ensuring the safety of drinking water.

Third, the upper casing 20 and the outer body 10 can be fast and accurately fitted and positioned by the structural design of the upper engaging frame 20a and the lower engaging frame 10a. The interlocking structure between the slot 222 and the insert block 124 of the outer body 10 , and the joint part 221 of the inner end of the upper shell 20 are screwed and locked to each other by the fastener 100 and the fixing seat 122 of the outer body 10 The design can further improve the assembling firmness of the upper case cover 10 and the outer body 20 with each other.

Fourth, the inner water outlet pipe 60 can be integrally formed with a plastic material, so that the plastic material has the rigidity of the material. In this way, when the inner water outlet pipe 60 is matched with the water inlet joint 63 at the inner end and the connecting pipe seat 314 of the inner body 30 is inserted into each other Nesting, and the water outlet head 64 at the outer end uses the second snap portion 642 and the first snap portion 123 of the outer body 10 to engage and locate each other, which can effectively ensure that the inner water outlet pipe 60 can be assembled quickly and securely. It is positioned between the outer body 10 and the upper cover 20 without using any fasteners.

Fifth, the inner body 30 can be easily and firmly assembled on the outer body 10 by using the bolt 300 to be screwed together through the joint seat 112 of the outer body 10 and the nut 200 whose rotation is restricted.

Sixth, by screwing the fixing screw 400 with the screw hole 116 of the outer body 10, the outer body 10 can be firmly assembled on the table 2, and the screw hole 116 for the fixing screw 400 to be assembled and fixed is provided. , and the through hole 114 through which the bolt 300 passes, both are disposed on the joint seat 112 , so the structure can be simplified, the production is easier, and the assembly operation is facilitated.

Seventh, by using the design of the pipeline limiting piece 33 and the limiting slot 327 on the inner body 30, the water inlet pipe set 40 can be easily, quickly and firmly fixed without using any fasteners, such as bolts, etc. It is limited to the inner body 30, so that there is no fear of loosening.

Eighthly, by utilizing the design of the detent hole 333 of the pipeline limiting piece 33 , it is convenient for the user to easily pick up and disassemble with a general tool or a specific tool.

As shown in Figures 18 to 21, the present invention further provides a second embodiment of a basin faucet. The basin faucet 1 is substantially the same as the basin faucet 1 of the first embodiment, and the difference is only:

In this embodiment, the inner water outlet pipe 60a is composed of a hose 65 connected to each other between the water inlet joint 63a and the water outlet head 64a.

The inner body 30a of the present embodiment does not have the design of the connecting pipe seat 314 of the first embodiment. Therefore, a part of the water inlet joint 63a of the present embodiment is directly inserted and positioned at the mixed water outlet 313 .

In addition, since the hose 65 does not have the rigidity of a rigid material, even if the water outlet head 64a can be snapped and positioned on the outer body 10 as in the first embodiment, it is still impossible to avoid the need to be inserted into the mixed water outlet 313 . The water inlet joint 63a may be suspected of being loose. Therefore, the inner body 30a of this embodiment has a hook block 344 protruding on the outer peripheral wall of the water inlet part 32 near the bottom end, and is equipped with a hose limiting piece 35. The hose limiting piece 35 has a plate body part 351 , a limiting insert 352 extending and bending from the front end of the plate part 351 , and a positioning hook part 353 extending and bending from the rear end of the plate part 351 , and the positioning hook part 353 is on the A hook hole 354 is formed for the hook to be positioned on the hook block 344; two sets of catch grooves 355 are formed on the plate body part 351, which can be nested and positioned on the cold water inlet pipe 41 and the hot water inlet pipe 41 of the water inlet pipe group 40 respectively. The opposite peripheral wall of the water inlet pipe 42; the limiting insert 352 has a limiting groove 356, which can be nested in the outer peripheral wall of the hose 65 close to the water inlet joint 63a, and at the same time abut the water inlet joint The outer side wall 63b of 63a can prevent the water inlet joint 63a from separating from the mixed water outlet 313, thereby solving the problem that the inner water outlet pipe 60a may not be assembled firmly due to the use of the hose 65.

The inner water outlet pipe 60a in this embodiment adopts a three-piece assembly design of the water inlet joint 63a, the water outlet head 64a and the hose 65. Compared with the inner water outlet pipe 60 which is integrally molded with plastic materials in the first embodiment, more The sub-segment molding design is simpler and faster to manufacture, and can obtain higher product yield, so the manufacturing cost is lower.

In this embodiment, two protruding posts 23 are protruded on the inner wall of the groove at the junction of the longitudinal housing cover 21 of the upper housing cover 20 and the upper half housing portion 22 , as shown in FIG. 22 . A screw hole 231 is provided. There are also two tightening bolts 24, which are respectively screwed with the screw holes 231 of the protruding column 23, and a part of the head 241 of the head 241 is respectively pressed against the opposite parts of the edge of the plate body part 351, which can effectively Therefore, the hose limiting piece 35 is prevented from being separated from the bottom of the inner body 30a.

The present utility model has been described in detail above and cited the embodiments, and it is obvious to those skilled in the art that various alternatives or modifications can be made according to the above description; therefore, all alternatives and modifications made on this basis and Modifications are included within the spirit and scope of the claims.
