Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures, and more particularly to a fixing structure for a side-opening faucet valve core seat. Background Technology

[0002] Side-opening faucets are widely used in modern life, and the methods for fixing the valve core seat of side-opening faucets are also very diverse. Currently, there are two common types of valve core seat fixing methods. One method is to push the valve core seat from the bottom of the faucet upwards to the side hole of the faucet, and then use a sleeve to fix the valve core seat to the inner wall of the faucet through the side hole with threads. This method has a stable structure, but it will limit the space inside the faucet cavity, which may affect the pulling effect of the pull tube. The other fixing method is to push the valve core seat from the bottom of the faucet upwards to the side hole of the faucet, and then use a sleeve to fix the valve core seat through the side hole with threads. This fixing method requires the threads to have sufficient strength. If the valve core seat is made of plastic or other materials with insufficient strength, it is difficult to ensure that the thread position will not deform or loosen under long-term stress.

[0003] In view of this, the purpose of this utility model is to provide a novel valve core seat fixing structure to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to develop a fixing structure for a side-opening faucet valve core seat that can both ensure the pulling space of the pull tube and ensure the fixing strength between the valve core seat and the faucet.

[0005] To achieve the purpose of this invention, this invention discloses a fixing structure for a side-opening faucet valve core seat, including a main body shell, the main body shell having a side-opening water spout, the side-opening water spout having an internal thread; A valve core seat, wherein the valve core seat is provided with at least two water inlet passages and one water outlet passage, and two corresponding water inlet holes and one water outlet hole are formed on the front end face of the valve core seat, and a metal support plate fixed to the main body and protruding from the main body is provided on the outside of the main body. At the side opening of the main body shell, there is a support end face that protrudes inward in a partial or complete circumferential direction. The unobstructed space of the support end face inside the water nozzle is suitable for the front end of the valve core seat and the metal support piece to pass through. The metal support piece protrudes from the rear wall of the main body and abuts against the support end face in a partial or complete manner, so as to provide a support force to the valve core seat using the support end face. A valve core sleeve is screwed into the internal thread of the side opening water nozzle, and at the same time, the protruding part of the metal support plate of the valve core seat is pressed, so that the metal support plate and the support end face form a pressing effect, so as to use the support end face to provide a support force to the valve core seat. A valve core is tightly inserted into the valve core sleeve, and a valve core pressure cap further seals and fixes the valve core to the front end face of the valve core seat through the internal thread of the side opening water nozzle. The inlet and outlet water passages of the valve core and the valve core seat are respectively connected.

[0006] Furthermore, the metal support plate has several protruding claws on its edge, and the support end face has grooves that correspond one-to-one with the claws, so that the claws of the metal support plate can pass through the corresponding grooves to achieve the positioning of the metal support plate and the support end face, thereby achieving the positioning effect of the valve core seat and the water nozzle.

[0007] Furthermore, the upper edge of the metal support plate is provided with an outwardly protruding arc-shaped boss, and the support end face is provided with an arc-shaped groove corresponding to the arc-shaped boss, so that the arc-shaped boss of the metal support plate can pass through the arc-shaped groove to realize the positioning of the metal support plate and the support end face, and further realize the positioning effect of the valve core seat and the water nozzle.

[0008] Furthermore, the outer wall above the support end face is provided with two protruding protrusions, and the two protrusions are spaced apart to form a retainer that matches the shape and size of the arc-shaped protrusion of the metal support plate. When the front end of the valve core seat and the metal support plate pass through the unobstructed space and push upwards at the same time, the arc-shaped protrusion is locked into the retainer, thereby achieving precise positioning between the valve core seat and the support end face.

[0009] Furthermore, the main body of the valve core seat is provided with an annular groove on its exterior, and the metal support plate is annular or semi-annular, with the metal support plate being nested within the annular groove to form a fixed structure.

[0010] Furthermore, a decorative cover and a handle are provided, wherein the decorative cover is screwed onto the valve core pressure cap, and the handle is fixed to the valve core's rotating core.

[0011] Furthermore, the valve core seat has at least two inlet passages and one outlet passage designed as right-angle passages. After the valve core seat is assembled, there is a sufficient redundant channel inside the main body shell where the valve core seat is located to allow the pull-out pipe to move.

[0012] With the above structure, a support end face is designed at the valve core seat mounting position on the main shell. Combined with the fixed metal support plate that matches the valve core seat, the push-fitting effect between the metal support plate and the support end face provides outward support for the valve core seat. The pressing action of the valve core sleeve on the valve core seat greatly increases the stress effect between the valve core seat and the main shell. This provides strong support for the valve core seat. During use, the valve core seat does not need to rest against the rear inner wall of the water nozzle, allowing for greater movement space for the pull-out tube. Simultaneously, since the stress between the valve core seat and the main shell is achieved through the support end face, the material requirements for the valve core seat are greatly reduced. High hardness and wear resistance are not required, thus ensuring the product's service life. This patented structure overcomes the problem of uneven pull-out tube operation due to product shape limitations. The valve core seat has high applicability and can be directly applied to multiple products, reducing costs. Attached Figure Description

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1-9 As shown, a fixing structure for a side-opening faucet valve core seat includes a main body shell 1, the main body shell 1 having a side-opening water nozzle 11, the side-opening water nozzle 11 having an internal thread 14. Valve core seat 2, such as Figure 1-3 As shown, the valve core seat 2 is provided with two water inlet passages 21 and one water outlet passage 22. Two water inlet holes 24 and one water outlet hole 25 are formed on the front end face 23 of the valve core seat 2. The outer side of the main body of the valve core seat 2 is provided with an annular groove 27. A metal support piece 26 protruding from the main body is nested in the annular groove 27 to form a fixed structure. In this embodiment, the metal support piece 26 is in an annular state and is nested in the annular groove 27.

[0017] like Figure 4-5As shown, at the side-opening water spout 11 of the main body shell 1, a support end face 12 is provided inside, either partially or entirely protruding inward in a circumferential direction. The unobstructed space 13 within the water spout of the support end face 12 is suitable for the front end face 23 of the valve core seat 2 and the metal support piece 26 to pass through. The metal support piece 26 protrudes from the rear wall of the main body and partially or entirely abuts against the support end face 12, thereby providing support for the valve core seat 2 using the support end face 12. In this embodiment, the edge of the metal support piece 26 is provided with several outwardly protruding claws 261, and the support end face 12 is provided with grooves 121 corresponding to the claws 261, so that the claws 261 of the metal support piece 26 can pass through the corresponding grooves 121, achieving… The positioning of the metal support plate 26 and the support end face 12 further achieves the positioning effect between the valve core seat 2 and the water nozzle; the upper edge of the metal support plate 26 is further provided with an outwardly protruding arc-shaped boss 262, the support end face 12 is provided with an arc-shaped groove 122 corresponding to the arc-shaped boss 262, and the upper outer wall of the support end face 12 is provided with two outwardly protruding blocks 123, and the two protruding blocks 123 are spaced apart to form a retaining seat 124 that matches the shape and size of the arc-shaped boss 262 of the metal support plate 26. When the front end face 23 of the valve core seat 2 and the metal support plate 26 pass through the unobstructed space 13 and push upward at the same time, the arc-shaped boss 262 is inserted into the retaining seat 124, realizing the precise positioning between the valve core seat 2 and the support end face 12.

[0018] like Figure 6 It can be seen that the two inlet passages 21 and one outlet passage 22 of the valve core seat 2 are first connected to the two inlet pipes 211 and one outlet pipe 221. Then, by holding the inlet and outlet pipes, the valve core seat 2 is inserted from the bottom of the main body shell 1. The front end face 23 of the valve core seat 2, with the metal support plate 26, passes through the unobstructed space 13. The claws 261 of the metal support plate 26 pass through the corresponding grooves 121, and the arc-shaped boss 262 passes through the arc-shaped grooves 122. Figure 7 As shown, after passing through, the metal support piece 26 is pushed upwards, and the arc-shaped protrusion 262 is engaged with the holder 124, thus achieving positioning. Figure 8 As shown, the metal support plate 26 is positioned upwards above the support end face 12. At this time, a valve core sleeve 3 is screwed into the internal thread 14 of the side opening nozzle 11, simultaneously pressing the protruding part of the metal support plate 26 of the valve core seat 2, so that the metal support plate 26 and the support end face 12 form a pressing effect, so that the support end face 12 provides a supporting force for the valve core seat 2, such as... Figure 9 As shown; A valve core 4 is tightly inserted into a valve core sleeve 3. The front end of the valve core is provided with a positioning post, which corresponds to the positioning hole on the front end face 23 of the valve core seat 2. By inserting the positioning post into the positioning hole, the two inlets and one outlet of the valve core 4 are sealed and connected to the two inlet holes 24 and one outlet hole 25 on the front end face 23 of the valve core seat 2. A valve core pressure cap 5 further seals and fixes the valve core 4 to the front end face 23 of the valve core seat 2 through the internal thread 14 of the side opening nozzle 11.

[0019] The valve core is further provided with a decorative cover 6 and a handle 7. The decorative cover 6 is screwed onto the valve core cap 5, and the handle 7 is fixed to the rotating core 41 of the valve core 4.

[0020] In this embodiment, as Figure 7-8 As shown, the valve core seat 2 has at least two inlet passages 21 and one outlet passage 22 designed as right-angle passages. After the valve core seat 2 is assembled with two inlet pipes 211 and one outlet pipe 221, due to the right-angle passage design, there is a sufficient redundant channel 8 in the main body shell 1 where the valve core seat 2 is located, for the movement of the pull-out pipe.

[0021] The above embodiments and illustrations are not intended to limit the product form and style of the present invention. Any appropriate changes and modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
