[0031] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0032] Example:

[0033] Reference Figure 1-Figure 3 As shown, the utility model discloses an automobile air conditioning pipe joint, comprising a joint body 1, wherein the joint body 1 comprises two hose joints 11. The two hose joints 11 are in the shape of a truncated cone. The vertical sections of the two hose joints 11 are both in the shape of a trapezoid.

[0034] The hose is inserted into the small end of the hose connector 11 .

[0035] The diameter of the small end of the hose connector 11 is 0.95-0.98 times the diameter of the inner hole of the hose. In this embodiment, the diameter of the small end of the hose connector 11 is 0.96 times the diameter of the inner hole of the hose.

[0036] The diameter of the large end of the hose connector 11 is 1.1-1.2 times the diameter of the inner hole of the hose. In this embodiment, the diameter of the large end of the hose connector 11 is 1.1 times the diameter of the inner hole of the hose.

[0037] The hose structure is configured in a truncated cone shape to facilitate the initial sleeve of the hose on the connector body 1. As the contact surface between the hose and the hose connector 11 gradually increases, the hose itself undergoes elastic deformation and the size of the hose opening gradually increases.

[0038] As the friction between the hose and the hose connector 11 gradually increases, the hose is initially fixed on the hose connector 11 .

[0039] The two ends of the connector body 1 extend outward to form a circular tube 3, and the hose connector 11 is located inside the corresponding circular tube 3. The outer circumference of the circular tube 3 is evenly provided with a plurality of first through holes 22 along its axial direction. One end of each first through hole 22 penetrates the corresponding circular tube 3.

[0040] Two clamping assemblies 2 are arranged on the connector body 1 , and the positions of the clamping assemblies 2 correspond to the positions of the corresponding hose connectors 11 . The clamping assemblies 2 fix the hose on the outer peripheral surface of the corresponding hose connector 11 .

[0041] Each pressing assembly 2 includes a plurality of pressing blocks 21. The number of the first through holes 22 on the round tube 3 is equal to the number of the pressing blocks 21 on the same round tube 3.

[0042] The pressing block 21 is disposed at the corresponding first through hole 22 , the pressing block 21 is slidably connected to the corresponding first through hole 22 , and a portion of the pressing block 21 is located outside the circular tube 3 .

[0043] Slide grooves 6 are provided on both sides of the inner wall of each first through hole 22 , and sliding bars 61 are provided on both sides of the pressing block 21 . The sliding bars 61 are located inside the corresponding slide grooves 6 , and the sliding bars 61 are slidably connected to the corresponding slide grooves 6 .

[0044] A side of the pressure block 21 close to the corresponding hose connector 11 is configured as an inclined surface.

[0045] The circular tubes 3 are all provided with a pushing assembly 4 , which drives a plurality of pressing blocks 21 on the same circular tube 3 to move together, so that the plurality of pressing blocks 21 fix the hose sleeved on the hose connector 11 .

[0046] The pushing assembly 4 includes a screw tube 41, which is arranged on the outer circumference of the corresponding round tube 3 and is threadedly connected to the corresponding round tube 3. The pressing blocks 21 are connected to the corresponding screw tube 41, and each pressing block 21 is rotatably connected to the corresponding screw tube 41.

[0047] The outer peripheral surface of the spiral tube 41 is provided with an anti-slip layer 5 .

[0048] The implementation principle of the above embodiment is:

[0049] The operator first preliminarily puts the hose on the corresponding hose connector 11 so that the inside of the hose is in preliminary contact with the surface of the hose connector 11. The operator then pushes the hose hard to slowly advance the hose to increase the contact area between the inside of the hose and the hose connector 11. The hose in contact with the hose connector 11 undergoes elastic deformation.

[0050] When the hose cannot be advanced any further, the operator stops pushing the hose.

[0051] Next, the operator rotates the screw tube 41, and the screw tube 41 moves along the axial direction of the corresponding circular tube 3, and the screw tube 41 drives several pressing blocks 21 connected thereto to move. As the pressing blocks 21 move, the bottom inclined surface of the pressing blocks 21 gradually contacts the surface of the hose, thereby further squeezing the hose to make the position of the hose more fixed.

[0052] When the solenoid 41 can no longer rotate, the operator stops the operation.

[0053] At this point, the hose has been connected to the pipe connector.

[0054] It is particularly noted that in the initial state, that is, when the distance between the bottom slope of the pressing block 21 and the corresponding hose connector 11 is the largest, the hose and the pressing block 21 are not in contact during the hose installation process.

[0055] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
