Description

Technical Field

[0001] This application relates to the technical field of electronic expansion valves, and particularly relates to a connection assembly for a refrigeration electronic expansion valve. Background Art

[0002] The electronic expansion valve uses the electrical signal generated by the regulated parameter to control the voltage or current applied to the expansion valve, thereby achieving the purpose of regulating the liquid supply. The stepless variable capacity refrigeration system has a wide range of refrigeration liquid supply regulation requirements and requires fast adjustment response. Traditional throttling devices (such as thermal expansion valves) are difficult to perform well, while the electronic expansion valve can meet the requirements well.

[0003] Currently, when the electronic expansion valve is connected and used, it is necessary to connect the connecting copper pipe to the pipeline. After the pipeline and the copper pipe are connected, the connection between the copper pipe and the pipeline is directly exposed. After long-term use, dirt will appear at the connection, causing the pipeline to rust, thus affecting the connection between the pipeline and the copper pipe. Therefore, a connection assembly for a refrigeration electronic expansion valve is designed to solve the above-mentioned problems. Utility Model Content

[0021] The following is a further detailed description of the present application in conjunction with the attached Figure 1-5 drawings.

[0022] The embodiment of the present application discloses a connection assembly for a refrigeration electronic expansion valve. Refer to Figure 1-5, A refrigeration electronic expansion valve connection assembly, including an electronic expansion valve body 1, a copper pipe 2 is installed on the electronic expansion valve body 1, an installation frame 3 is installed on the copper pipe 2, the installation frame 3 can slide on the copper pipe 2, a protection pipe 4 is fixedly connected to the lower end of the installation frame 3, the protection pipe 4 covers the copper pipe 2, a protection ring 5 is fixedly connected to the lower end of the protection pipe 4, a rotating ring 6 is rotatably connected to the outer side wall of the protection ring 5, equidistant limiting chutes 61 are opened on the rotating ring 6, a sliding rod 7 is slidably connected in the limiting chute 61, and the limiting chute 61 is as Figure 3 shown, for limiting the movement track of the sliding rod 7, a moving plate 8 is rotatably connected to the sliding rod 7, one side of the moving plate 8 is rotatably connected to a limiting rod 9 after rotation, the moving plate 8 can rotate slightly with the center of the limiting rod 9 as the axis, and the upper end of the limiting rod 9 is fixedly connected to the protection ring;

[0023] When the rotating ring 6 rotates clockwise, and during the rotation, the chute 61 drives the sliding rod 7 to move, so that the sliding rod 7 drives the moving plate 8 to move when moving, and makes the moving plate 8 rotate with the limiting rod 9 as the axis, as Figure 3 shown, and makes the inner sides of multiple moving plates 8 approach each other to form a circular groove, and makes the side wall of the moving plate 8 contact the side wall of the pipeline, thereby clamping the pipeline, so that the position of the protection pipe 4 is fixed, so that the moving plate 8 clamps the pipeline, so that the protection pipe 4, the installation frame 3 and the moving plate 8 protect the connection between the pipeline and the copper pipe 2.

[0024] By adopting the above technical solution, the installation frame 3 is an annular frame, springs 31 are fixedly connected to the front, rear, left and right sides inside the installation frame 3, a clamping plate 32 is fixedly connected to the side of the spring 31 away from the inner wall of the installation frame 3, the clamping plate 32 clamps the copper pipe 2, and the spring 31 is used to drive the clamping plate 32 to move, so that the clamping plate 32 always clamps the copper pipe 2, so that the installation frame 3 can not only move on the copper pipe 2 by pulling the installation frame 3 when needed, but also use the clamping action of the clamping plate 32 to keep the installation frame 3 installed on the copper pipe 2 after moving.

[0025] By adopting the above technical solution, the inner diameter width of the protection ring 5 is greater than the diameter of the copper pipe 2, so that when the protection pipe 4 drives the protection ring 5 to descend, it is avoided that the protection ring 5 rubs against the copper pipe 2 and causes wear.

[0026] By adopting the above technical solution, limiting frames 10 are fixedly connected to both sides of the protection pipe 4, as Figure 2 shown, a driving rod 11 is slidably connected in the limiting frame 10, the two driving rods 11 are centrosymmetric, the lower end of the driving rod 11 is fixedly connected to the protection ring 5, and the driving rod 11 can slide in the limiting frame 10.

[0027] By adopting the above technical solution, sliding blocks 12 are fixedly connected to both sides of the driving rod 11, and the sliding blocks 12 are slidably connected to the side wall of the limiting frame 10, so that the driving rod 11 moves more stably in the limiting frame 10.

[0028] By adopting the above technical solution, through grooves 101 are formed in the front and rear parts of the upper end of the limit frame 10. A push block 102 is slidably connected in the through groove 101. The upper end of the driving rod 11 is provided with a fixing groove, an elastic piece 111 is fixedly connected in the fixing groove, and an insertion block 112 is fixedly connected to the upper end of the elastic piece 111. The push block 102 can be pushed, so that the push block 102 drives the insertion block 112 to descend into the fixing groove and the elastic piece 111 contracts, so that the driving rod 11 is no longer limited by the insertion block 112, and thus the driving rod 11 can move in the limit frame 10.

[0029] The implementation principle of a connection assembly of a refrigeration electronic expansion valve in an embodiment of the present application is as follows: The copper pipe 2 of the electronic expansion valve body 1 is connected to a pipeline. After the connection, the installation frame 3 can be pulled downward, so that the installation frame 3 drives the clamping plate 32 and the spring 31 to move on the surface of the copper pipe 2, and drives the protection pipe 4 to descend, so that the protection pipe 4 covers the connection part of the copper pipe 2 and the pipeline, and the lower protection ring 5 and the rotating ring 6 descend close to the pipeline. Then, the push block 102 can be pushed, so that the push block 102 drives the insertion block 112 to descend into the fixing groove and the elastic piece 111 contracts, so that the driving rod 11 is no longer limited by the insertion block 112. After that, the driving rod 11 is rotated clockwise, so that the driving rod 11 drives the rotating ring 6 to rotate clockwise. When rotating, the limit sliding groove 61 drives the sliding rod 7 to move, so that the sliding rod 7 drives the moving plate 8 to move when moving, and the moving plate 8 rotates around the limit rod 9 as the axis, as Figure 3 shown, and the inner sides of the plurality of moving plates 8 approach each other to form a circular groove, and the side wall of the moving plate 8 contacts the side wall of the pipeline, so as to clamp the pipeline, so that the position of the protection pipe 4 is fixed. After moving, the elastic piece 111 in the driving rod 11 drives the insertion block 112 to rise, so that the insertion block 112 is inserted into the fixing groove 101 again, so as to fix the driving rod 11, so that the moving plate 8 and the rotating ring 6 are fixed, ensuring the stable protection of the protection pipe 4 and the protection ring 5.
