Description

Quick installation structure of body in tap

Technical Field

The invention belongs to a water tap, and particularly relates to a structure for simply, quickly and firmly mounting an inner body of the water tap.

Background

US6757921 discloses a right-angle valve block (right-angle valve block) installed in a hollow body from a side opening, but has certain disadvantages when installed, and US2019/0085538 thus modifies the right-angle valve block to be installed from the bottom end of the hollow body upwardly through a longitudinal cavity to improve the disadvantages.

However, such a structural change is still not perfect, and in the case of the structure of the first example, when the right-angle valve block is inserted into the longitudinal chamber from the bottom of the housing seat upwards, and slightly transversely moving towards the valve groove installation direction to ensure that the sealing gasket slightly passes through the communication port, the right-angle valve block is also required to be adjusted to ensure that the second positioning hole is respectively aligned with each first positioning hole to form the rotation limiting hole so as to allow each convex column on the subsequently installed positioning element to be aligned with each rotation limiting hole, because the assembly mode is difficult to assemble by only depending on the hand feeling and must be observed by naked eyes, the assembly position is close to the inner side of the valve installing groove, but not by naked eyes, and the function of guiding and positioning is not added, so that the positioning error is easy to be caused by slight positioning error, and the required rotation limiting holes cannot be accurately formed together, and at the moment, the convex columns 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 position accurately, and the positioning elements are composed of two members, the number of the members increases, and the assembly complexity increases, so the assembly is still difficult, and is not easy and fast. The positioning member of the fifth embodiment only needs a single simple component similar to a C-shaped ring, but has the disadvantages that a special tool is needed to elastically expand the positioning member for positioning, and the space in the valve groove for installation is small, so that it is not easy to perform such an operation, and therefore, it is still difficult to achieve the effect of easy and quick installation.

In order to explain the technical solution of the present invention, the following detailed description is made with reference to the specific drawings and examples.

Referring to fig. 1 to 3, the present invention provides a first embodiment of a quick-mounting structure for a faucet inner body, which is a pull-out faucet 1. as is known, a pull-out faucet 1 typically includes a hollow faucet body 10, a control valve assembly 20 for mounting on the faucet body 10, a water supply line 30 mounted in communication with the control valve assembly 20, a water outlet hose 40 in communication with the water supply line 30 for delivering water, and a spray head 50 positioned at a water outlet end 100 of the faucet body 10 for communicating with the water outlet hose 40.

In this embodiment, the faucet body 10 includes a housing 10a, and a water outlet elbow 10b extending from the top of the housing 10 a; as shown in fig. 4 to 6, a longitudinal chamber 11 and a mounting valve 12 extending in a transverse direction are formed inside the housing seat 10a, a communication opening 13 is formed at a boundary between the inner side of the mounting valve 12 and the longitudinal chamber 11, and a mounting inlet 14 is formed at the outer side of the mounting valve 12. The mounting valve spool 12 of this embodiment is formed in a valve seat portion 120 that projects laterally outwardly of the housing seat 10 a.

In the present embodiment, as shown in fig. 1 to 3, the control valve set 20 further includes an inner body 21, a mixing valve 22, a valve cover 23, a decoration cover 24 and a handle 25; at least a portion of the inner body 21 is receivable within the mounting valve spool 12; the mixing valve 22 can be accommodated in the mounting valve spool 12 and communicated with the inner body 21; the valve cover 23 can be screwed on the faucet body 10 to tightly press the mixing valve 22 in the mounting valve housing 12, for example, internal threads can be provided on the inner wall of the mounting valve housing 12 near the outer side for screwing and locking the valve cover 23.

In the present embodiment, the water supply pipeline 30 is installed at the bottom of the inner body 21 and includes a cold water inlet pipe 31, a hot water inlet pipe 32 and a mixed water outlet pipe 33; when the cold water and the hot water respectively flow into the control valve set 20 from the cold water inlet pipe 31 and the hot water inlet pipe 32 to be properly mixed, mixed water can flow from the mixed water outlet pipe 33 to the spray head 50 through the communicated water outlet hose 40 to be discharged, a user can pull out the spray head 50 according to requirements for use, and the spray head 50 can automatically return to be positioned at the water outlet end 2a after being released.

In this embodiment, a weight 60 is further included for being mounted on the water outlet hose 40 to provide a restoring force for automatically retracting the spray head 50 after releasing.

However, the above components and related structures are well known in the art and are not the focus of the present invention, so they are not described herein in detail.

The main improvement of this embodiment lies in:

as shown in fig. 4 to 6, the faucet body 10 is provided with two positioning ribs 131 at the communication opening 13, which are opposite to each other and have a stepped shape.

The inner body 21, as shown in fig. 7 to 9, can be inserted from the bottom of the longitudinal cavity 11 of the faucet body 10, and has a protruding portion 210, which can be transversely inserted into the mounting valve slot 12 through the communication port 13 between the positioning ribs 131 and is connected and communicated with the mixing valve 22, and two lateral positioning slots 211 are disposed adjacent to the protruding portion 210, which can be respectively nested in each of the corresponding positioning ribs 131 from top to bottom along the longitudinal direction, as shown in fig. 10, so that the inner body 21 cannot be transversely separated 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, and similarly, the protruding portion 210 of the inner body 21 is also substantially wide at the top and narrow at the bottom, so that the communication opening 13 with wide at the top and narrow at the bottom can just allow the protruding portion 210 with wide at the top and narrow at the bottom to pass through, but when the protruding portion 210 moves from the top to the bottom along the longitudinal direction, the transverse snap-in limiting effect can be generated.

In the present embodiment, the inner body 21 is formed with a convex positioning wall 212 below the protruding portion 210, and the convex positioning wall can be tightly attached to the concave opposite portion of the inner peripheral wall 121 of the mounting valve 12 of the faucet body 10 along the longitudinal direction from top to bottom, as shown in fig. 10, by the above-mentioned arc concave-convex matching design, the inner body 21 can be ensured to be kept at the middle position without deviation.

As shown in fig. 2, 3, 7 and 8, the quick-mounting structure for an inner body of a faucet of the present embodiment further includes a positioning collar 26, which is mounted and positioned between the protruding portion 210 of the inner body 21 and the mounting valve slot 12 from the mounting inlet 14 of the faucet body 10, for preventing the lateral positioning slot 211 of the inner body 21 from longitudinally separating from the corresponding positioning ribs 131 of the faucet body 10 from bottom to top.

More specifically, a slot 213 is formed at the top end of the protruding portion 210 of the inner body 21, and a lateral limiting outer wall 214 is formed at each of two opposite sides, and a lower limiting outer wall 215 is formed at the bottom end; the positioning collar 26 defines a trepanning 261 for being nested in the protruding portion 210 of the inner body 21, and the top end of the positioning collar 26 is provided with an elastic hook 262 protruding for being elastically and slidably buckled and clamped in the slot 213, two opposite edges of the inner peripheral wall of the trepanning 261 are respectively formed with a lateral limiting inner wall 263 for abutting and limiting against the opposite lateral limiting outer walls 214, and the bottom end is formed with a lower limiting inner wall 264 for abutting and limiting against the lower limiting outer wall 215; the positioning collar 26 further extends inside with two annular walls 266 opposite to the 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 limited and restrained by the elastic hook 262, the lower limiting inner wall 264 and the lateral limiting inner wall 263 of the positioning collar 26, as shown in fig. 11, and 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, at least the inner body 21 is ensured not to move from the bottom to the top, and meanwhile, after the positioning collar 26 and the inner body 21 are mutually nested and positioned, on one hand, the elastic hook 262 and the slot 213 can be mutually buckled to limit the positioning collar 26 from transversely separating from the inner body 21 towards the outer side, on the other hand, the annular wall 266 can be used for limiting the positioning rib 131 to separate the positioning collar 26 from the inner body 21 towards the inner side, so that the firmness of assembling the positioning collar 26 and the inner body 21 with each other can be ensured, and achieves the main effect of preventing the lateral positioning slot 211 of the inner body 21 from longitudinally disengaging from the positioning ribs 131.

The inner body 21 of the present embodiment can be integrally formed by plastic material, which is helpful to form more complicated structures, such as the above-mentioned elastic hooks 262, and ensure proper elasticity or flexibility.

In the present embodiment, the protruding portion 210 of the inner body 21 has a guiding edge 267 formed outside the slot 213 for guiding the elastic hook 262 to be slidably inserted into the slot 213.

In the present embodiment, the lower limiting inner wall 264 of the positioning collar 26 further has at least one rib 268 extending along the installation direction, as shown in fig. 7, 8 and 11, so that when the positioning collar 26 is sleeved on the inner body 21, the rib 268 can be tightly pressed against the lower limiting outer wall 215 to prevent the positioning collar 26 from being loosened in the radial direction.

In the embodiment, the protruding portion 210 of the inner body 21 is formed with a rear-side stopping plane 216 adjacent to the lateral limiting outer wall 214, and the positioning rib 131 is formed with a front-side stopping plane 132 opposite to the rear-side stopping plane, so that when a user locks the valve cover 23, the axial locking force along the installation valve slot 12 can act on the protruding portion 210 of the inner body 21 transversely through the mixing valve 22, so that the rear-side stopping plane 216 can be pressed against the front-side stopping plane 132, thereby ensuring that the inner body 21 can achieve a tight fixing effect in the axial direction without generating axial looseness.

In this embodiment, as shown in fig. 12 and 13, the inner body 21 has a water inlet passage 217a, a water outlet passage 217b and a mixed water passage 217c, and a cold water inlet connection hole 218a, a hot water inlet connection hole 218b and a mixed water outlet connection hole 219c are formed at the bottom end thereof for inserting and positioning the cold water inlet tube 31, the hot water inlet tube 32 and the mixed water outlet tube 33 of the water supply line 30, respectively, a cold water communication port 219a, a hot water communication port 219b and a mixed water communication port 219c for communicating the mixing valve are formed at the protruding portion 210, and a card slot 217 for communicating the cold water inlet connection hole 218a, the hot water inlet connection hole 218b and the mixed water outlet connection hole 218c is transversely formed below the protruding portion 210; a locking piece 27 for being transversely inserted into and positioned in the card slot 217 so as to be nested and positioned in the cold water inlet pipe 31, the hot water inlet pipe 32 and the mixed water outlet pipe 33, thereby achieving the effect of locking and positioning. It should be noted that, a positioning wall 111 is formed on the inner peripheral wall of the longitudinal cavity 11 of the faucet body 10, so that the outer side wall 271 of the locking piece 27 mounted on the inner body 21 can be abutted against the positioning wall 111 in the mounted state, as shown in fig. 3, thereby preventing the locking piece 271 from being released laterally.

In the present embodiment, two assembling tool holes 269 are symmetrically disposed on the outer side wall surface of the positioning collar 26, as shown in fig. 7, so that a specific tool can be inserted and positioned, after the positioning collar 26 is installed into the installation valve slot 12 from the installation inlet 14, the specific tool can be operated to adjust the assembling angle and orientation of the positioning collar 26, and at the same time, the positioning collar 26 is axially pushed toward the inner body 21, so as to be accurately and quickly assembled on the inner body 21.

As shown in fig. 14 to 18, the present invention further provides a second embodiment of a quick-mounting structure for a faucet inner body, which is substantially the same as the first embodiment, and the difference is only that:

the inner body 21a of this embodiment is provided with two slots 213, which are respectively located at two side portions; the positioning ring 26a is also provided with two elastic hooks 262 respectively located at two side portions of the sleeve hole 261, and can be respectively and elastically slidably fastened and positioned with the corresponding slots 213 when the positioning ring 26a is sleeved on the inner body 21 a.

The inner body 21a of this embodiment also has two lateral limiting outer walls 214 and the position collar 26a also has two lateral limiting inner walls 263, but in a slightly different position from the first embodiment.

In this embodiment, two arc-convex positioning walls 212 are provided below the protruding portion 210 of the main body 21a, but the area is smaller than that of the single positioning wall 212 of the first embodiment.

In this embodiment, the protruding portion of the inner body 21a is also formed with a guiding edge 267 at the outer side of each slot 213 for guiding the elastic hook to be inserted into each corresponding slot by the rear sliding buckle.

As shown in fig. 19 to 23, the present invention further provides a third embodiment of a quick-mounting structure for a faucet inner body, which is different from the first embodiment in that:

the present embodiment does not have the positioning collar 26 of the first embodiment, but the inner body 21b of the present embodiment is substantially the same as the inner body 21 of the first embodiment, and the difference is that a positioning notch 218 is formed below the protruding portion 210, and a positioning block 122 is protruded from the bottom of the inner peripheral wall 121 of the faucet body 10 where the valve housing 12 is installed near the communication opening 13, so that the positioning notch 218 can be nested and positioned on the positioning block 122 from top to bottom along the longitudinal direction, so as to ensure that the inner body 21b can be kept at the middle position without generating the deviation.

Furthermore, the positioning latch 122 of the present embodiment is a tapered structure with a narrow top and a wide bottom, so that the positioning latch 122 can be smoothly guided into the positioning latch groove 218.

As shown in fig. 24 to 26, the present invention further provides a fourth embodiment of a quick-mounting structure for a faucet inner body, which is substantially the same as the third embodiment, and the difference is only that:

in the present embodiment, a bolt 28 is used to replace the positioning fixture 122 of the third embodiment.
