[0027] Please see Figure 1-6 A precision copper pipe fitting for refrigeration equipment includes a connector 1, both sides of which are open structures. The connector 1 has detachable copper pipe fittings 2 on both sides inside the connector 1. Rubber sealing rings 3 are fixedly connected to the ends of the two copper pipe fittings 2 that are close to each other.

[0028] Specifically, the surface of the rubber sealing ring 3 is in contact with the inner wall of the connector.

[0029] Specifically, by setting the rubber sealing ring 3, the sealing performance between the connector 1 and the copper pipe fitting 2 is improved.

[0030] Specifically, the end of the copper pipe fitting 2 away from the rubber sealing ring 3 passes through the connector 1 and extends to the outside of the connector 1.

[0031] In practice, the top and bottom of the copper pipe fitting 2, and the outside of the connector 1, are fixedly connected to the fixing blocks 4. The fixing blocks 4 are in movable contact with the connector 1, and the fixing blocks 4 have through holes 5 on the side near the connector 1.

[0032] Specifically, a threaded rod 6 is movably inserted into the through hole 5. The end of the threaded rod 6 away from the connector 1 passes through the through hole 5 and extends to the outside of the through hole 5, while the end of the threaded rod 6 near the connector 1 is fixedly connected to the connector 1. The diameter of the through hole 5 is slightly larger than the diameter of the threaded rod 6.

[0033] In practice, the threaded rod 6 is connected to the external thread of the through hole 5 with a threaded sleeve 7, and the threaded sleeve 7 is in movable contact with the fixed block 4.

[0034] Specifically, by engaging the threaded sleeve 7 with the threaded rod 6, the connector 1 and the copper pipe fitting 2 can be firmly fixed together.

[0035] Specifically, two movable grooves 8 are symmetrically opened on the front of the left and right sides of the connector 1. The front and rear sides of the inner wall of the movable groove 8 are fixedly connected by the connecting post 9. A slider 10 is slidably connected to the rear side of the surface of the connecting post 9.

[0036] In practice, the left side of the slider 10 passes through the movable groove 8 and extends to the outside of the movable groove 8 and is fixedly connected to a U-shaped stop 11. The slider 10 and the movable groove 8 are movably connected, and the side of the U-shaped stop 11 near the connector 1 is movably abutting against the screw sleeve 7.

[0037] Specifically, by setting the U-shaped stop 11, the threaded sleeve 7 can be limited to prevent it from disengaging from the threaded rod 6, thereby greatly improving the connection stability between the connector 1 and the copper pipe fitting 2.

[0038] Specifically, a spring 12 is fitted on the surface of the connecting column 9 and on the front side of the slider 10.

[0039] Specifically, by setting spring 12, a supporting force can be provided for slider 10.

[0040] Specifically, the front sides of the two U-shaped blocks 11 on the same side are fixedly connected to the same arc-shaped block 13, and the surface of the arc-shaped block 13 is fixedly fitted with a handle 14.

[0041] Specifically, the grip 14 is provided with anti-slip texture, which makes it easier to pull the curved block 13.

[0042] In practical applications: When it is necessary to separate the two copper pipe fittings 2, simply pull the handle 14 forward to move the arc block 13, U-shaped stop 11, and slider 10 forward, simultaneously compressing the spring 12. This causes the U-shaped stop 11 to disengage from the threaded sleeve 7 and move to the front of the fixing block 4. Then, rotate the threaded sleeve 7 counterclockwise, causing it to move away from the connector on the threaded rod 6, thus disengaging it from the threaded rod 6. Then, pull the copper pipe fitting 2 outward to disengage it from the connector 1 and the threaded rod 6 from the through hole 5, allowing the copper pipe fitting 2 to be removed and the disassembly completed. Similarly, during assembly, pulling the handle 14 forward will move the arc block 13, U-shaped stop 11, and slider 10 forward to the appropriate position. Then, insert the copper pipe fitting 2 into the connector 1, and make the fixing block 4 abut against the connector 1. At the same time, insert the threaded rod 6 into the corresponding through hole 5. Then, put the threaded sleeve 7 on the threaded rod 6, and then rotate the threaded sleeve 7 clockwise, so that the threaded sleeve 7 moves towards the side of the connector 1 on the threaded rod 6, and then makes the threaded sleeve 7 abut against the fixing block 4. Then, release the handle 14, and under the action of the spring 12, drive the slider 10 and the U-shaped stop 11 to reset, so that the U-shaped stop 11 contacts the threaded sleeve 7. Thus, the U-shaped stop 11 limits the threaded sleeve 7, preventing the threaded sleeve 7 from disengaging from the threaded rod 6, and improving the connection stability between the threaded sleeve 7 and the threaded rod 6. Through the above steps, the two copper pipe fittings 2 can be easily spliced ​​and disassembled. The operation is simple, time-saving and labor-saving.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
