Technical Field

[0001] This application relates to the field of shower pipe technology, and in particular to a high-strength metal shower pipe. Background Technology

[0002] A shower hose is a flexible pipe connecting the shower head and faucet, typically composed of metal end caps and a corrugated hose, primarily used for conveying water flow. The end caps and corrugated hose are usually cast in one piece, making the connection structure easily damaged during use due to impacts, stretching, compression, etc. Therefore, there is an urgent need for a metal shower hose with a more stable connection structure between the end caps and the corrugated hose. Utility Model Content

[0013] 1. This application improves the thickness of the connection between the bellows and the end cap by setting a solid fitting part embedded in the recess of the inner circumference end of the bellows, thereby improving the stability of the connection structure. By setting a hollow fitting part in other recesses of the bellows, the hollow fitting part has a certain toughness, which provides a certain buffering force when the bellows is compressed, effectively protecting the bellows.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] This application provides a high-strength metal shower pipe, such as Figures 1 to 5As shown, it includes an end cap 1, a bellows 2 and multiple connectors 3. The end cap 1 is a cylindrical structure, connected to the end of the bellows 2 and coaxially arranged with the bellows 2. The inner circumference of the end cap 1 is provided with a first thread 11 and a second thread 12 in sequence along the direction from the cap opening to the bellows 2. The first thread 11 is used to connect to the threaded interface of the water heater, and the second thread 12 is connected to a retaining ring 4.

[0024] Specifically, such as Figures 2 to 4 As shown, one end of the retaining ring 4 has a third thread 42, which engages with the second thread 12. The retaining ring 4 is connected to the inner circumference of the end cap 1 through the third thread 42. The inner circumference of the retaining ring 4 is provided with multiple sets of anti-slip textures 44 along the axial direction. Each set of anti-slip textures 44 is arranged around the circumference of the retaining ring 4. The anti-slip textures 44 increase the friction between the user's hand and the retaining ring 4 when rotating the retaining ring 4 to engage the second thread 12 and the third thread 42, preventing slippage during installation and facilitating installation. The outer circumference of the retaining ring 4 has an annular boss 41, which forms a gap with the inner side of the end cap 1. The outer circumference of the annular boss 41 also has multiple stops 45, which are evenly arranged. Multiple connectors 3 are circumferentially spaced, and the multiple stops 45 are used to stop the connectors 3.

[0025] like Figures 2 to 5 As shown, the retaining ring 4 and the connector 3 are made of PVC. The connector 3 is an arc-shaped structure that circumferentially mates with the corrugated pipe 2. The connector 3 includes a mounting part 31, a solid fitting part 32, and a hollow fitting part 33, which are sequentially connected and integrally injection molded. The mounting part 31 is attached to the inner circumference of the end cap 1, and a gap is formed between the mounting part 31 and the inner side of the end cap 1. An arc-shaped groove 311 matching the annular boss 41 is formed at the end of the mounting part 31 facing away from the solid fitting part 32. The end of the arc-shaped groove 311 and the edge of the annular boss 41 are each provided with rounded corners. The arc-shaped groove 311 fits into the annular boss 41. The connection structure between the connector 3, the bellows 2, and the end cap 1 is reinforced. The solid fitting part 32 and the hollow fitting part 33 are embedded in the recesses of the inner circumference of the bellows 2. The solid fitting part 32 is embedded in the recess of the inner circumference end of the bellows 2. In this way, the thickness of the connection part between the bellows 2 and the end cap 1 is increased, thereby improving the stability of the connection structure. By setting the hollow fitting part 33 in other recesses of the bellows 2, the hollow fitting part 33 has a certain toughness, which provides a certain buffer force when the bellows 2 is compressed, effectively protecting the bellows 2.

[0026] During installation, the high-strength metal shower pipe of this application first inserts the connector 3 into the corrugated pipe 2, and applies force to embed the solid fitting part 32 into the recess at the inner circumference end of the corrugated pipe 2. The hollow fitting part 33 then fits into the recess at the rear. Next, the mounting part 31 is pressed along the direction close to the inner side of the end cap 1, so that the end of the arc-shaped groove 311 slides into the gap between the annular protrusion and the end cap 1, thereby making the annular groove fit with the annular protrusion and completing the fixation of the connector 3 and the retaining ring 4. Compared with the prior art, the high-strength metal shower pipe of this application adds a connector 3 that can strengthen the stability of the connection structure between the end cap 1 and the corrugated pipe 2. The connector 3 has a simple structure and is easy to install.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
