Description

Technical Field

[0001] This utility model relates to the field of compressor refrigeration pipe fittings, and in particular to a compressor refrigeration pipe fitting that is easy to assemble. Background Technology

[0002] Compressor refrigeration fittings refer to the pipes and components used to connect and assist the operation of compressors. There are various types of compressor refrigeration fittings, and when using them, it is usually necessary to assemble adjacent compressor refrigeration fittings.

[0003] The assembly of adjacent compressor refrigeration pipes in the prior art usually uses mounting rings, bolts and nuts. The mounting rings are welded to the outside of the compressor refrigeration pipe and are located at the end of the compressor refrigeration pipe, so that the two mounting rings are mated together. Then, bolts are used to connect the two mounting rings. Nuts cooperate with bolts to make the two mounting rings fit tightly, thus completing the assembly of adjacent compressor refrigeration pipes.

[0004] However, the connection between adjacent compressor refrigeration pipes is usually exposed to the outside. At the same time, the operating environment of compressor refrigeration pipes is diverse, which may lead to external liquids or other substances corroding or contaminating the connection between adjacent compressor refrigeration pipes. This can affect the subsequent separation and assembly of compressor refrigeration pipes. Therefore, it is necessary to provide external protection for the connection after the adjacent compressor refrigeration pipes are assembled. Utility Model Content

[0039] First fitting 1;

[0040] The second pipe fitting 2 is located on the side of the first pipe fitting 1. Both the first pipe fitting 1 and the second pipe fitting 2 are used for compressor refrigeration.

[0041] Two mounting rings 3 are respectively fixedly inserted and connected to the outside of the first pipe fitting 1 and the second pipe fitting 2. The mounting rings 3, bolts 4 and nuts enable the first pipe fitting 1 and the second pipe fitting 2 to be connected and assembled, which facilitates operation.

[0042] Bolt 4 is inserted into two mounting rings 3, and a nut is threadedly connected to the end of bolt 4;

[0043] The protective mechanism 5 is fitted onto the outside of the mounting ring 3. The protective mechanism 5 is used to shield and protect the first pipe fitting 1 and the second pipe fitting 2.

[0044] Furthermore, the protection mechanism 5 includes two protective semi-cylinders 51, a snap-fit ​​assembly, and a transparent plate 59.

This facilitates shielding and protection between the first pipe fitting 1 and the second pipe fitting 2 after assembly, preventing external contamination and erosion at the connection between the first pipe fitting 1 and the second pipe fitting 2, and improving the stability of the connection between the first pipe fitting 1 and the second pipe fitting 2. The transparent plate 59 facilitates the viewing of the pipe fittings. The connection between the first pipe fitting 1 and the second pipe fitting 2 is observed to understand the connection between the first pipe fitting 1 and the second pipe fitting 2. The two protective half cylinders 51 are provided with arc-shaped grooves on opposite sides, which is conducive to the close fitting and installation of the protective half cylinders 51. The exterior of the first pipe fitting 1 and the second pipe fitting 2 are slidably inserted into the inner cavity of the arc-shaped groove. The snap-fit ​​assembly is located outside the protective half cylinder 51. The snap-fit ​​assembly is used to snap and fix the two protective half cylinders 51. The exterior of the protective half cylinder 51 is provided with a slot, and the transparent plate 59 is embedded in the inside of the slot.

[0045] Specifically, the snap-fit ​​assembly includes a mating plate 52, a receiving plate 53, a drive frame 54, a sliding plate 55, a positioning post 56, an operating plate 57, a mounting rod, and a spring 58. The mating plate 52 and the receiving plate 53 facilitate the support of the two protective half-cylinders 51, making it easy to assemble them. The drive frame 54 is L-shaped and facilitates the movement of the positioning post 56, allowing it to disengage from the inner cavity of the positioning groove. The sliding plate 55 facilitates the movement of the drive frame 54, allowing the drive frame 54 and the positioning post 56 to move together. During drive operation, the positioning post 56 helps to define the relative position of the drive frame 54 and the receiving plate 53, which in turn helps to define the relative position of the docking plate 52 and the receiving plate 53, facilitating the snap-fit ​​assembly of the two protective half-cylinders 51 and simplifying operation. The operating plate 57 facilitates the simultaneous movement of the two sliding plates 55 in the same row, enabling quick assembly.

The movement facilitates the return of the sliding plate 55 and positioning post 56 to their original positions, allowing for repeated operation of the positioning post 56 and drive frame 54. The docking plate 52 is fixedly connected to the side of one of the protective half-cylinders 51, and a first groove is formed on the top of the docking plate 52. The receiving plate 53 is fixedly connected to the outside of the other protective half-cylinder 51. The drive frame 54 is slidably mounted on the docking plate 52 and the receiving plate 53. The sliding plate 55 is fixedly connected to the top of the drive frame 54. The positioning post 56 is fixedly connected to the side of the inner wall of the drive frame 54. The operating plate 57 is fixedly connected to... At the top of the sliding plate 55, the mounting rod is threadedly connected to the side of the mating plate 52. The spring 58 is sleeved on the outside of the mounting rod. Both the mounting rod and the spring 58 are located inside the first sliding groove. One end of the spring 58 is in contact with the sliding plate 55, and the other end of the spring 58 is in contact with the inner wall of the first sliding groove. The bottom of the inner wall of the first sliding groove is provided with a second sliding groove that is adapted to the drive frame 54.
