[0035] Referring to Figure 2 - Figure 4 , the inner wall of insertion cylinder 31 is provided with mounting bin 32, the inner wall of mounting bin 32 is fixedly connected with sealing ring 33, the shape of sealing ring 33 is annular, the material of sealing ring 33 is set as rubber, by the material setting of sealing ring 33, ensure that sealing ring 33 has deformation ability, to ensure that sealing ring 33 is pushed from inside, can make it move outward, and after deformation, reach the effect that its outer side is attached with the inner wall of connecting cylinder 1, the inner wall below sealing ring 33 at mounting bin 32 is slidably connected with push ring 34, the shape of push ring 34 is annular with straight angle trapezoidal cross section, by the shape setting of push ring 34, ensure that the bottom end of push ring 34 is forced to move upward, under the action of its inclined surface, push sealing ring 33, make it produce the force of moving outward, the bottom end of push ring 34 is fixedly connected with control ring 35, the shape of control ring 35 is circular ring, and the lower end outer side of control ring 35 is provided with angle cut.

[0036] Referring toFigure 2 - Figure 5 A slider 36 is slidably connected to the bottom end of the installation chamber 32. The slider 36 is cuboid in shape. A control rod 37 is fixedly connected to the bottom end of the slider 36. Multiple sliders 36 and control rods 37 are used, and the combined structure of multiple sliders 36 and control rods 37 is arranged in a circular array around the axis of the insertion cylinder 31. The control rod 37 is cylindrical. A rotating chamber 38 is formed on the inner wall of the insertion cylinder 31 below the installation chamber 32. The outer wall of the control rod 37 is slidably connected to the inner wall of the insertion cylinder 31 between the installation chamber 32 and the rotating chamber 38. The insertion cylinder 31... A groove is provided on the inner wall between the installation chamber 32 and the rotating chamber 38 for the control rod 37 to move. A rotating ring 39 is rotatably connected to the inner wall of the rotating chamber 38. The rotating ring 39 is circular in shape. A control groove 310 is provided at the top of the rotating ring 39. The control groove 310 is arc-shaped. There are multiple control grooves 310, and the number of control grooves 310 is the same as the number of control rods 37 and sliders 36. The distance between different positions of the same control groove 310 and the center of the insertion cylinder 31 is different. The bottom end of the control rod 37 is set in the control groove 310.

[0037] Reference Figure 5 - Figure 7 The interior of the rotating ring 39 and the interior of the insertion cylinder 31 are jointly provided with a fixing component 4. The fixing component 4 includes a moving groove 41, and an insertion block 42 is slidably connected to the inner wall of the moving groove 41. An insertion hole 43 is opened on the inner wall of the connecting cylinder 1. The insertion block 42 is cylindrical in shape, and the end of the insertion block 42 is set with rounded corners. By setting the rounded corners, it is ensured that the insertion block 42 does not need to be completely aligned with the insertion hole 43, but can enter the insertion hole 43 after moving to a position close to the insertion hole 43. A pull rod 44 is fixedly connected to the end of the insertion block 42 away from the insertion hole 43. A groove is opened on the end of the pull rod 44 away from the insertion block 42. The design allows the operator to easily pull the lever 44. The end of the insert 42 near the lever 44 is elastically connected to the inner wall of the moving groove 41 via a spring 45. One end of the spring 45 is fixedly connected to the end of the insert 42 near the lever 44, and the other end of the spring 45 is fixedly connected to the inner wall of the moving groove 41. The spring 45 is located on the outside of the lever 44. The outer arc surface of the insert cylinder 31 is provided with a sliding groove 46. The included angle between the two ends of the sliding groove 46 is consistent with the included angle between the two ends of the single control groove 310. The width of the sliding groove 46 matches the diameter of the lever 44.

[0038] Working principle: When in use, the operator first inserts the top protrusion of the insertion tube 31 into the bottom of the connecting tube 1, and then pulls the pull rod 44 outward, so that the pull rod 44 pulls the insertion block 42, thereby driving the insertion block 42 to move outward and leave the insertion hole 43.

[0039] When the plug 42 leaves the socket 43, the worker moves the pull rod 44, so that the rotating ring 39 moves in the interior of the rotating bin 38, so that the intersection between the control groove 310 in the sliding position of the control rod 37 and the midpoint of the insertion cylinder 31 is shortened, so that the control rod 37 is controlled by the control groove 310 and moves towards the middle part of the insertion cylinder 31, so that the slider 36 moves towards the middle part of the insertion cylinder 31, so that the slider 36 pushes the inclined surface of the control ring 35, so that it moves upwards.

[0040] When the control ring 35 moves upwards, the control ring 35 drives the pushing ring 34 to move upwards, so that the cutting angle outside the pushing ring 34 pushes the sealing ring 33, so that the inner side of the bottom end of the sealing ring 33 is subjected to a pushing force, so that it generates a moving force outwardly. Because the sealing ring 33 can be deformed, the sealing ring 33 moves outwardly under the premise of being deformed, so that the outer wall thereof is attached to the inner wall of the connecting cylinder 1.

[0041] When the rotating ring 39 rotates to the appropriate position, the plug 42 is just in the engagement position with another socket 43 at this time, so that when the worker releases the hand of the control pull rod 44 at this time, the plug 42 can move towards the direction of entering the socket 43 under the elastic force of the spring 45, so that the plug 42 enters the socket 43, so as to ensure that the pipeline is not easy to fall off during the normal use of the automobile air conditioner.

[0042] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
