Detailed Description

The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.

The embodiment of the invention comprises the following steps: as shown in fig. 1-3, a hose coupling includes a main pipe body 1, the main pipe body 1 is a circular pipe structure, a first connecting pipe 2 is fixedly arranged at one end of the main pipe body 1, a second connecting pipe 3 is fixedly arranged at the other end of the main pipe body 1, the first connecting pipe 2 and the second connecting pipe 3 are integrated into a whole, so that liquid leakage can be effectively prevented, a first pipe pressing component is arranged on the first connecting pipe 2, and a second pipe pressing component is arranged on the second connecting pipe 3.

During the use, press the pipe subassembly through first after inserting a hose and first connecting pipe 2 and compress tightly, prevent to break away from, then press the pipe subassembly to compress tightly with second connecting pipe 3 and another hose grafting and through the second, prevent to break away from. The whole installation process can be completed in only one or two minutes, and the first pressure pipe assembly and the second pressure pipe assembly are arranged, so that the connection stability and firmness can be improved.

It should be noted that the main pipe body 1, the first connecting pipe 2 and the second connecting pipe 3 may be made of rigid plastic, or may be made of metal, and the surface of the main pipe body, the first connecting pipe 2 and the second connecting pipe may need to be subjected to anti-corrosion treatment.

In order to enable various vehicle types to adopt the connection mode, the first connecting pipe 2 and the second connecting pipe 3 can be designed into an equal-size mode, namely the outer diameter and the inner diameter of the first connecting pipe 2 and the second connecting pipe 3 are equal; it is also possible to design the connection pipes in different sizes, i.e. the first connection pipe 2 has an outer diameter that is larger than the outer diameter of the second connection pipe 3. The size of the pipe orifice of the actual flexible connecting pipe of the automobile type can be specifically selected.

In a specific embodiment, the first pipe pressing component comprises a first jaw 6 and a first locking nut 7, the first jaw 6 is arranged at equal intervals along the circumferential direction of the first connecting pipe 2, one end of the first jaw 6 is fixedly connected with the main pipe body 1, the other end of the first jaw 6 is a free end, a gap is formed between the first jaw 6 and the first connecting pipe 2, a first thread 8 is arranged on the outer wall of the first jaw 6, the first locking nut 7 is sleeved on the main pipe body 1, and the first locking nut 7 is in threaded connection with the first jaw 6.
