The outer contact sleeve 2 is located on the outer side of the outer circle of the bending portion 11, and the first inner contact sleeve 3 and the second inner contact sleeve 4 are located on the inner side of the inner circle of the bending portion 11. The inner sides of the outer contact sleeve 2, the first inner contact sleeve 3 and the second inner contact sleeve 4 are all in contact with the bending portion 11. The edge of the outer contact sleeve 2 is provided with an inclined first locking edge 21 and a second locking edge 22, the first locking edge 21 is provided with a first locking groove 211, and the second locking edge 22 is provided with a second locking groove 221, the first inner contact sleeve 3 is provided with an inclined first connecting edge 31, the first connecting edge 31 is provided with a first protrusion 311, and the first protrusion 311 is embedded in the first locking groove 211, the second inner contact sleeve 4 is provided with an inclined second connecting edge 41, the second connecting edge 41 is provided with a second protrusion 411, and the second protrusion 411 is embedded in the second locking groove 221.

[0016] Through the above technical solution, during production and installation, the straight tube is first bent according to the specifications to form a hard tube body 1, and then the outer contact sleeve 2 is attached to the outside of the bending portion 11, and the first inner contact sleeve 3 is attached to the straight portion 12 on one side of the bending portion 11, and then it is pushed toward the bending portion 11. During this process, the first protrusion 311 is embedded in the first locking groove 211, and then the second inner contact sleeve 4 is attached to the straight portion 12 on the other side of the bending portion 11, and then it is pushed toward the bending portion 11. During this process, the second protrusion 411 is embedded in the second locking groove 221. The first locking edge 21 and the second locking edge 22 are obliquely arranged at the end of the outer contact sleeve 2, and the first connecting edge 31 and the second connecting edge 41 are obliquely arranged, so that the rear end surfaces of the first inner contact sleeve 3 and the second inner contact sleeve 4 connected to the outer contact sleeve 2 are flat.

[0017] By providing an outer contact sleeve 2, a first inner contact sleeve 3 and a second outer contact sleeve 2 made of metal at the bending portion 11, the conduction area of ​​the bending portion 11 is increased, the influence of temperature changes is reduced, and the bending portion 11 is wrapped inside to improve the compressive resistance of the bending portion 11, thereby improving the compressive resistance of the hard tube body 1.

[0018] As an improved specific implementation manner, an anti-scratch tube 5 is provided on the outer side of the straight portion 12 , and a buffer tube 6 is provided between the anti-scratch tube 5 and the straight portion 12 .

[0019] Through the above technical solution, the anti-scratch tube 5 protects the buffer tube 6 and the hard tube body 1 to avoid scratching the buffer tube 6 and the hard tube body 1. The buffer tube 6 isolates and absorbs vibrations, stabilizes the environment of the hard tube body 1, reduces the impact on the connection, thereby avoiding leakage at the connection and improving the pressure resistance.

[0020] As an improved specific embodiment, a receiving groove 51 is provided at the end of the anti-scratch tube 5, and a clamping groove 52 is provided on the opposite side of the receiving groove 51, and the clamping groove 52 is communicated with the receiving groove 51. A clamping edge 23 is provided on the outer side of the outer contact sleeve 2, and the clamping edge 23 is embedded in the clamping groove 52. A first contact block 32 is provided on the outer side of the first inner contact sleeve 3, and a second contact block 42 is provided on the outer side of the second inner contact sleeve 4. The first contact block 32 contacts the end of the anti-scratch tube 5 on this side, and the second contact block 42 contacts the end of the anti-scratch tube 5 on this side.

[0021] Through the above technical scheme, the anti-scratch tube 5 and the rubber tube are already sleeved on the outside of the pipe before the pipe is bent; after the outer contact sleeve 2, the first inner contact sleeve 3, and the second inner contact sleeve 4 are installed on the bending portion 11, the anti-scratch tube 5 is pushed toward the bending portion 11, and the position of the accommodating groove 51 is first aligned with the card edge 23 until the card edge 23 contacts the bottom of the accommodating groove 51, and then the anti-scratch tube 5 is rotated 180° so that the card edge 23 completely enters the card groove 52. At this time, the first contact block 32 and the second contact block 42 respectively contact the ends of the anti-scratch tube 5 on the corresponding side straight portion 12, and then are fixed with glue.

[0022] The card edge 23 is embedded in the card groove 52 to fix the outer contact sleeve 2, the first contact block 32 contacts the anti-scratch tube 5, fixes the first inner contact sleeve 3, the second contact block 42 contacts the anti-scratch tube 5, and fixes the second inner contact sleeve 4, so as to prevent the outer contact sleeve 2, the first inner contact sleeve 3, and the second inner contact sleeve 4 from loosening, thereby improving stability during use.

[0023] As an improved specific implementation, the card slot 52 and the card edge 23 are both inclined.

[0024] Through the above technical solution, the card slot 52 and the card edge 23 are both inclined. As the anti-scratch tube 5 rotates, the card edge 23 is continuously inserted into the card slot 52 for a tight connection, further improving the structural strength after the connection.

[0025] As an improved specific implementation, the buffer tube 6 is a rubber tube with bubbles inside, and the rubber tube is deformable.

[0026] Through the above technical scheme, the rubber tube can be deformed under the participation of external force, so as to prevent the temperature change of the internal environment of the hard tube body 1, causing the internal pipeline to expand and contract, and prevent the air-conditioning pipeline from rupture due to the change in volume. It also has better thermal insulation performance, so that the hard tube body 1 can maintain good pressure resistance.

[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
