[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-9 As shown, a multi-layered, bend-resistant water pipe includes a pipe body 1 and a connector 9 installed at the end of the pipe body 1. The connector 9 is used to install a faucet, and water flows into the pipe body 1 through the connector 9. The pipe body 1 includes an inner layer 2 and an outer layer 3, with the outer layer 3 wrapping around the outer contour of the inner layer 2. The inner layer 2 includes a corrugated tube with a wavy contour, providing good bend resistance and a certain degree of elasticity, allowing it to spring back to its original position after bending. The outer layer 3 includes braided threads and is fitted around the outer contour of the corrugated tube, serving to protect the inner layer 2.

[0032] A protective layer 4 is fitted onto the pipe body 1, wrapping around the outer contour of the outer layer 3. This protective layer 4 protects the pipe body 1 from damage caused by external forces or excessive bending, and also increases the thickness of the water pipe, further enhancing its resistance to bending. This multi-layered design enhances the water pipe's resistance to bending, preventing cracking caused by frequent bending, increasing the pipe's lifespan, and ensuring high product quality.

[0033] The protective layer 4 includes a plastic protective layer, which has a certain degree of elasticity and is relatively hard, effectively protecting the tube body 1. It is not easily damaged by accidental drops or being stepped on, and it also has strong resistance to bending.

[0034] The outer layer 3 shown includes a yarn braided layer or a fabric sheath layer. The yarn braided layer is formed by weaving on the inner layer surface. The yarn is woven on the inner layer surface, and then the protective layer 4 is wrapped on the outer layer surface through an extruder, so that the inner layer 2, outer layer 3 and protective layer 4 are integrated. The fabric sheath layer is formed by attaching a fabric sheath to the inner layer surface, and then the protective layer 4 is wrapped on the outer layer surface through an extruder, so that the inner layer 2, outer layer 3 and protective layer 4 are integrated. The extruder in this invention is a traditional plastic water pipe extruder.

[0035] Due to the corrugated shape of the inner layer 2, a wave-shaped cavity 5 structure is formed between the inner layer 2 and the outer layer 3, which has a certain anti-torsion ability and prevents the water pipe from getting tangled during use.

[0036] The joint 2 is provided with a connecting pipe 10 extending outward on one side, the pipe body 1 is sleeved on the connecting pipe 10 through the inner layer 2, the connecting pipe 10 is provided with a connecting part 11 between the pipe body 1 and the connecting pipe 10, the pipe body 1 is tightly connected with the joint 9 through the connecting part 11, and falling off in practical process is prevented.

[0037] The diameter of the connecting pipe 10 is slightly larger than the inner diameter of the pipe body, when the pipe body 1 is sleeved on the connecting pipe 8, the pipe body 1 can be expanded by the elasticity of the pipe body 1, and the connection is more tight.

[0038] The connecting part 11 comprises a threaded connecting part, the threaded connecting part is connected in a threaded connection mode through mutual cooperation of an inner thread and an outer thread; the connecting part 11 also comprises a buckle connecting part, the buckle connecting part is connected in a mode that a buckle is embedded into a clamping groove, and the user is facilitated to disassemble.

[0039] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but rather can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and not restrictive, the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of the equivalent elements of the claims are intended to be embraced in the present application, and any reference signs in the claims should not be considered as limiting the involved claims.
