Description

[Technical Field]

[0001] This utility model relates to the field of faucet technology, specifically to an improved shower faucet angle valve. [Background Technology]

[0002] The shower faucet angle valve is a key component connecting the water supply pipe and the shower equipment. Commonly used shower faucet angle valves include a body and a water passage section, which can be an inlet and an outlet section.

[0003] For example, appendix Figure 1-3 A prior art shower faucet angle valve 200 is shown, including an inlet section 201 and an outlet section 202. The outlet section 202 is externally connected to a connector component 203 for connecting external devices such as hoses. The connector component 203 typically consists of an inner barb 204, an outer nut 205, and a bolt 209. The inner barb 204 includes an outer protruding edge 206, a connecting portion 207, and a threaded connection portion 208. When installing the connector component 203 to the outlet section 202, the inner barb 204 is first inserted into the outer nut 205, then the threaded connection portion 208 is threaded onto the outlet section 202, and finally, the bolt 209 is used to tighten the outer nut 205 onto the connecting portion 207. This shower faucet angle valve 200 has the following technical defects:

[0004] 1. Poor stability of single-point connection between connector component 203 and water outlet 202: Since the shower faucet angle valve 200 needs to be rotated frequently during use, this single-point threaded connection is prone to loosening after long-term use, especially when the length of the threaded part 208 is designed to be short. More seriously, the connection point is prone to oxidation, which further weakens the connection strength and ultimately increases the risk of connector component 203 falling off the water outlet 202 significantly.

[0005] 2. In an attempt to improve the connection strength between the inner barb 204 and the outer nut 205, the existing technology typically employs a method of lengthening the connecting portion 207. However, this lengthening of the connecting portion 207 inevitably leads to a corresponding shortening of the length of the threaded portion 208 that effectively connects the inner barb 204 and the water outlet 202. This design presents a clear paradox: lengthening the connecting portion 207 increases the material usage and cost of the inner barb 204, without directly participating in the main stress-bearing connection point between the connector component 203 and the water outlet 202. Therefore, this structure in the existing technology neither truly achieves connection stability nor increases manufacturing costs.

[0006] In view of this, this case involves in-depth research into the aforementioned issues, which led to the formation of this case. [Utility Model Content]

[0007] This utility model aims to solve the technical problem of unstable connection between existing connector components and the water passage section. It provides an improved shower faucet angle valve, which breaks through by changing the connection point between the connector component and the water passage section to a two-point connection of "the nut directly locking into the groove of the water passage section + the reverse screw connecting to the water passage section". The groove design enhances the mechanical interlocking force, combined with the radial locking of the first bolt, and the coordinated reverse screw threaded connection with the water passage section, significantly improving the connection stability between the connector component and the water passage section. This avoids the risk of loosening and oxidation of the connector component, and saves material costs by greatly shortening the length of the reverse screw. It achieves breakthroughs in stability, lifespan and cost, and has both innovation and industrial practicality.

[0008] This utility model is implemented as follows: An improved shower faucet angle valve includes an angle valve body. The outer wall of the angle valve body extends to form a water passage. The water passage includes a first end fixedly connected to the angle valve body and a second end away from the angle valve body. The second end is detachably connected to a connector component. A groove is provided in the circumferential direction in the middle of the outer wall of the water passage. The connector component includes a nut, a stud, and a first bolt for locking the nut in the groove. The stud is installed inside the nut and connected to the water passage. The nut has a through hole in the radial direction, and the first bolt is installed in the through hole.

[0009] Furthermore, the inner wall of the nut is provided with an inner convex ring, and the second end abuts against the inner convex ring.

[0010] Furthermore, the reverse screw includes a threaded portion for threaded connection with the water passage section and a raised edge for abutting against the inner convex ring.

[0011] Furthermore, the threaded portion forms a first external thread, and the inner wall of the water-passing portion forms a first internal thread for engaging with the first external thread.

[0012] Furthermore, the reverse screw also includes a sealing ring. The reverse screw has a first sealing groove recessed on the outer wall between the threaded portion and the outer convex edge, and a second sealing groove recessed on the inner wall of the second end. The first sealing groove and the second sealing groove together form an installation groove for installing the sealing ring.

[0013] Furthermore, the convex edge includes a first outer convex ring and a second outer convex ring, the first outer convex ring being disposed opposite to the inner convex ring; the outer diameter of the second outer convex ring is larger than the outer diameter of the first outer convex ring and abuts against the inner convex ring.

[0014] Furthermore, the inner wall of the protruding edge is provided with a second internal thread.

[0015] Furthermore, the nut is an external hexagonal nut, and the inner wall of the external hexagonal nut has a third internal thread.

[0016] Furthermore, the water passage is a water outlet, and the water passage channel is an outlet channel.

[0017] Furthermore, the water-passing part is a water inlet part, and the water-passing channel is a water inlet channel.

[0018] The advantages of this utility model are:

[0019] 1. The improved shower faucet angle valve uses the external nut groove locking mechanism as its core, and breaks through the traditional single-point threaded connection between the connector component and the water passage part to a double-point connection between the nut, the external nut, and the water passage part. The radial locking of the groove and the first bolt forms a rigid fixation, which completely solves the problem of poor connection stability and easy detachment caused by the short external nut thread in traditional designs. In addition, the overall length of the external nut is shortened, reducing production costs. This design does not reduce the connection strength but increases the connection strength between the connector component and the water outlet part, and also extends the service life.

[0020] 2. The improved shower faucet angle valve achieves breakthroughs in stability, lifespan, and cost, combining innovation with industrial practicality. [Attached Image Description]

Detailed Implementation Methods

[0034] To better understand the technical solution of this utility model, the technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Please see Figure 4-9 As shown, an improved shower faucet angle valve 100 includes an angle valve body 1. The outer wall of the angle valve body 1 extends to form a water passage 2. The water passage 2 forms a water passage 26. The water passage 2 includes a first end 21 fixedly connected to the angle valve body 1 and a second end 22 away from the angle valve body 1. The second end 22 is detachably connected to a connector component 3. The middle of the outer wall of the water passage 2 has a groove 23 in the circumferential direction. The connector component 3 includes a nut 31, a screw 32, and a first bolt 33 for locking the nut 31 into the groove 23. The screw 32 is installed inside the nut 31 and connected to the water passage 2. The nut 31 has a through hole 311 in the radial direction, and the first bolt 33 is installed in the through hole 311. The connection point between the connector component 3 and the water passage part 2 is changed to a two-point connection of "nut 31 directly locking into the groove 23 of the water passage part 2 + reverse screw 32 connecting to the water passage part 2", replacing the traditional single-point screw connection between the reverse screw 32 and the water passage part 2. The groove 23 design enhances the mechanical interlocking force, and combined with the radial locking of the first bolt 33, it significantly improves the connection stability between the connector component 3 and the water passage part 2. This avoids the risk of loosening and oxidation of the connector component 3, and saves material costs by greatly shortening the length of the reverse screw 32.

[0036] In this invention, the nut 31 includes a third end facing the water passage 2 and a fourth end away from the water passage 2; the third end is the inlet end of the water passage 2. The inner wall of the nut 31 is provided with an inner convex ring 312, and the second end 22 abuts against the inner convex ring 312. The inner convex ring 312 is positioned close to the third end to control the maximum path of the water passage 2 into the nut 31. The distance from the inner convex ring 312 to the third end of the nut 31 is the first connecting section between the nut 31 and the water passage 2, and a through hole 311 is provided on the first connecting section. The distance from the inner convex ring 312 to the fourth end is the second connecting section between the nut 31 and external equipment (hose).

[0037] In this utility model, as shown in the appendix Figure 7-8 As shown, the reverse screw 32 includes a threaded portion 321 for threaded connection with the water-passing part 2 and a raised edge portion 322 for abutting against the inner convex ring 312. The threaded portion 321 forms a first external thread 3211, and the inner wall of the water-passing part 2 forms a first internal thread 24 for engaging with the first external thread 3211. The threaded portion 321 is responsible for sealing the connection with the water-passing part 2, and the raised edge portion 322 abuts against the inner convex ring 312 to form a double fixation, preventing loosening. The reverse screw 32 of this utility model does not require a long connecting part, shortening the overall length. The length of the threaded portion 321 is the same as the length of the conventional reverse screw 32, and the threaded engagement structure is standardized, reducing the processing difficulty.

[0038] In this utility model, the inverted screw 32 also includes a sealing ring 323. The inverted screw 32 has a first sealing groove 324 recessed on the outer wall between the threaded portion 321 and the raised edge portion 322, and a second sealing groove 25 recessed on the inner wall of the second end 22. The first sealing groove 324 and the second sealing groove 25 together form an installation groove for installing the sealing ring 323. The double sealing groove design ensures that the sealing ring 323 is accurately pressed between the inverted screw 32 and the water passage portion 2, improving the sealing reliability and preventing leakage.

[0039] In this utility model, the convex edge portion 322 includes a first outer convex ring 3221 and a second outer convex ring 3222. The first outer convex ring 3221 is disposed opposite to the inner convex ring 312. The outer diameter of the first outer convex ring 3221 is less than or equal to the inner diameter of the inner convex ring 312. The outer diameter of the second outer convex ring 3222 is greater than the outer diameter of the first outer convex ring 3221 and abuts against the inner convex ring 312.

[0040] In this invention, the inner wall of the protruding edge 322 is provided with a second internal thread 3223, which cooperates with a wrench to support quick assembly and disassembly. Preferably, the second internal thread 3223 is an internal hexagonal thread.

[0041] In this utility model, the nut 31 is an external hexagonal nut 31, which is convenient for tool operation; the inner wall of the external hexagonal nut 31 has a third internal thread 313 (see attached drawing). Figure 4The third internal thread 313 is formed in the second connecting section, and the third internal thread 313 supports quick connection with other components (such as hoses) to improve installation efficiency.

[0042] In this invention, the water-passing part 2 is a water outlet part, and the water-passing channel 26 is an outlet channel. Alternatively, the water-passing part 2 is a water inlet part, and the water-passing channel 26 is an inlet channel.

[0043] The structural design of the water passage section 2 is compatible with both the water inlet and water outlet sections, making it highly versatile; the locking mechanism of the groove 23 is applicable to all types of water passages, solving the connection stability problem of different water passage channels.

[0044] In this invention, a valve core 4 is installed at one end of the angle valve body 1. The valve core 4 can be used to switch the water outlet mode.

[0045] The improved shower faucet angle valve 100 of this utility model has at least the following beneficial technical effects: With the locking of the outer nut 31 and groove 23 as the core, it innovatively improves the connection point between the connector component 3 and the water passage part 2 from a single-point threaded connection of "reverse screw 32 and water passage part 2" to a double-point connection of "nut 31, reverse screw 32 and water passage part 2". Rigid fixation is formed by the radial locking of the groove 23 and the first bolt 33, which, together with the threaded connection of the reverse screw 32 and the water passage part 2, completely solves the problem of poor connection stability and easy detachment caused by the excessively short threaded portion 321 of the traditional reverse screw 32. Furthermore, the overall length of the reverse screw 32 is shortened, reducing production costs. This design does not reduce connection strength but rather increases the connection strength between the connector component 3 and the water passage part 2, and also extends the service life. The improved shower faucet angle valve 100 achieves breakthroughs in stability, service life, and cost, combining innovation and industrial practicality.

[0046] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
