Background technique

U.S. Patent No. US6757921 discloses a pull-out faucet in which a right-angle valve block (right-angle valve block) is installed into a hollow body from a side opening, but there are some disadvantages in its installation. Therefore, U.S. Patent Publication No. US2019/ 0085538 changed the right-angle valve block to a structure and method of installing from the bottom of the hollow body upwards through a longitudinal chamber to improve its shortcomings.

However, such a structural change is still not perfect. Taking the structure of the first example as an example, when the right-angle valve block is inserted into the longitudinal chamber from the bottom of the housing base, and moves slightly laterally toward the direction of installing the valve slot, When the sealing gasket slightly passes through the communication port, the right-angle valve block must be adjusted so that the second positioning holes are respectively aligned with the first positioning holes to form the rotation-limiting holes, so as to allow the positioning elements installed subsequently The protrusions are aligned with the rotation-limiting holes. Because this assembly method is difficult to assemble only by hand feeling, it must be observed with the naked eye, but the assembly position is close to the inside of the installation valve slot, which can not be clearly observed by the naked eye. In addition, there is no guide positioning function, it is easy to be unable to accurately form the required rotation-limiting holes together due to slight positioning deviations. At this time, the protrusions cannot be smoothly positioned in the rotation-limiting holes.

The second to fourth embodiments also have the problem that the first embodiment is not easy to locate accurately, and the positioning elements are all composed of two components, the number of components increases, and the complexity of assembly also increases, so the assembly is still difficult. Not easy and fast enough. The positioning part of the fifth embodiment only needs a single simple member similar to a C-shaped ring, but the disadvantage is that a specific tool must be used to elastically stretch the positioning part and position it, and the space in the installation valve slot is narrow, so it is not easy to perform such an operation. Easy, therefore, it is still difficult to achieve the effect of simple and fast installation.

In this embodiment, a weight 60 is further included, which can be installed on the water outlet hose 40 so as to provide a restoring force for automatically retracting the spray head 50 after it is released.

However, the above components and related structures are all known technologies, and are not the focus of the present invention, so they will not be described here.

The main improvements of this embodiment are:

As shown in FIGS. 4 to 6 , the faucet body 10 is provided with two step-like positioning ribs 131 opposite to each other at the communication opening 13 .

The inner body 21, as shown in Figures 7 to 9, can be inserted from the bottom of the longitudinal chamber 11 of the faucet body 10, and has a protruding part 210, which can be inserted through the communication opening 13 between the positioning ribs 131 in the transverse direction. The installation valve slot 12 is in communication with the mixing valve 22, and the protruding part 210 is adjacent to a two-sided positioning groove 211, which can be nested in each relative positioning protrusion from top to bottom along the longitudinal direction. Ribs 131 , as shown in FIG. 10 , make it impossible for the inner body 21 to disengage laterally from the mounting valve slot 12 .

It should be noted that, in this embodiment, the communication opening 13 formed between the left and right positioning ribs 131 is wide at the top and narrow at the bottom. Similarly, the protruding part 210 of the inner body 21 is generally wide at the top and narrow at the bottom. Therefore, the upper wide and lower narrow communication port 13 can just allow the upper wide and lower narrow protruding part 210 to pass through, but when the protruding part 210 moves from top to bottom in the longitudinal direction, it can produce Horizontal buckle limit effect.

In this embodiment, the inner body 21 is formed with an arc-convex positioning wall 212 below the protruding part 210, which can fit against the installation valve slot of the faucet body 10 along the longitudinal direction from top to bottom. The inner peripheral wall 121 of 12 is a concave arc-shaped opposite part, as shown in FIG. 10 , the above-mentioned arc-shaped concave-convex cooperation design can ensure that the inner body 21 can be kept in the middle position without misalignment.

As shown in Figures 2, 3, 7 and 8, the quick installation structure of the inner body of the faucet of this embodiment further includes a positioning collar 26, which can be installed and positioned from the installation entrance 14 of the faucet body 10 to the protrusion of the inner body 21. The position 210 and the installation valve slot 12 are used to prevent the lateral positioning grooves 211 of the inner body 21 from longitudinally detaching from the corresponding positioning ribs 131 of the faucet body 10 from bottom to top.

More specifically, a locking groove 213 is formed at the top of the protruding part 210 of the inner body 21, and a lateral limiting outer wall 214 is formed on each of two opposite sides, and a lower limiting outer wall 215 is formed at the bottom; the positioning sleeve The ring 26 defines a set of holes 261, which can be nested in the protruding part 210 of the inner body 21, and an elastic hook 262 protrudes from the top of the positioning collar 26, and can be inserted into the slot 213 by the elastic slide buckle. The two opposite sides of the inner peripheral wall of the sleeve hole 261 are respectively formed with a lateral limiting inner wall 263, which are respectively used to abut against the opposite lateral limiting outer walls 214, and the bottom end is formed with a lower limiting inner wall 264, which can The positioning collar 26 is further extended with two ring-shaped walls 266 corresponding to the respective positioning ribs 131 of the faucet body 10 . Accordingly, since the top end, the bottom end and the two opposite sides of the inner body 21 are respectively constrained by the elastic hook 262 of the positioning collar 26, the lower limit inner wall 264 and the lateral limit inner wall 263, As shown in FIG. 11 , in addition, the outer peripheral wall 265 of the positioning collar 26 and the inner peripheral wall 121 of the installation valve slot 12 are mutually nested and limited, and cannot move along the radial direction. Therefore, at least the inner body 21 can be guaranteed It will not move from bottom to top. At the same time, since the positioning collar 26 and the inner body 21 are nested and positioned, on the one hand, the elastic hook 262 and the slot 213 can be interlocked to restrict the positioning collar. 26 is laterally separated from the inner body 21 toward the outside, and on the other hand, the positioning collar 26 can be restricted from the inner body 21 toward the inner side by means of the annular wall 266 relative to each positioning rib 131. Therefore, it is possible to ensure The firmness of the positioning collar 26 and the inner body 21 is assembled together, and achieves the main function of preventing the lateral positioning grooves 211 of the inner body 21 from detaching from the positioning ribs 131 longitudinally.

The inner body 21 of this embodiment can be molded integrally with plastic material, which helps to form more complex structures, such as the above-mentioned elastic hook 262 , and ensure proper elasticity or flexibility.

In this embodiment, the protruding portion 210 of the inner body 21 forms a guide edge 267 on the outside of the slot 213 , so as to guide the elastic hook 262 and thereby the slide buckle to be engaged in the slot 213 .

In this embodiment, the lower limit inner wall 264 of the positioning collar 26 is further provided with at least one rib 268 extending along the installation direction, as shown in FIGS. When the inner body 21 is used, the ribs 268 can press against the lower limiting outer wall 215 to prevent the positioning collar 26 from loosening in the radial direction.

In this embodiment, the protruding part 210 of the inner body 21 forms a rear side stop plane 216 adjacent to the lateral limiting outer wall 214, and the positioning rib 131 forms a front side stop plane 132 oppositely, When the user locks the valve cover 23, the axial locking force along the installation valve slot 12 can act laterally on the protruding part 210 of the inner body 21 through the mixing valve 22, so that the rear side stops The flat surface 216 is pressed against the front blocking flat surface 132 , thereby ensuring that the inner body 21 is tightly fixed in the axial direction without axial looseness.
