AI Technical Summary
The lack of retaining rings on the mounting bolts of existing compressors results in a large amount of movement between the bolts and bushings, making them prone to falling off and causing equipment damage.
Design an installation bolt that includes a nut, a disc, and an anti-loosening mechanism. The anti-loosening mechanism consists of a pull rod, a crossbar, a locking block, and a spring. The spring force causes the crossbar to lock into the groove of the compressor threaded hole, preventing the bolt from coming off.
This effectively prevents bolts from detaching from the platform during prolonged use, avoids compressor falling, and improves the equipment's stability and reliability.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of mounting bolt technology, specifically a mounting bolt for a compressor. Background Technology
[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it by driving a piston through the motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle. When in use, the compressor usually needs to be fixed to a corresponding platform using mounting bolts.
[0003] For example, a non-detachable bolt assembly for plastic end caps, with announcement number "CN206682127U," uses a T-shaped bushing for direct contact with various external plastic end caps, making it less prone to deformation and suitable for high-torque installation applications of various plastic end caps. However, this non-detachable bolt assembly for plastic end caps lacks a retaining ring on the bolt, relying instead on the outer diameter of the thread for restriction. This results in a large clearance between the bolt and the bushing, making the bolt prone to loosening and potentially causing the equipment to fall and be damaged. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that the bolt does not have a retaining ring and is limited by the outer diameter of the thread, resulting in a large amount of clearance between the bolt and the bushing, which easily leads to the bolt falling off and causing damage to the equipment. Therefore, a mounting bolt for a compressor is proposed.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] Design a mounting bolt for a compressor, including a nut and a disc. A disc is fixedly connected to the bottom of the disc. An anti-detachment mechanism is provided inside the disc. The anti-detachment mechanism includes a pull rod. A crossbar is fixedly connected to the bottom of each of the two pull rods. A locking block is fixedly connected to the inner side of each crossbar. Multiple springs are provided on the outer side of each locking block. The two ends of each spring are fixedly connected to the disc and the locking block, respectively.
[0007] Preferably, the crossbar is slidably connected to the inner walls of the left and right sides of the disk.
[0008] Preferably, the pull rod is slidably connected to the inner walls on both sides above the disk.
[0009] Preferably, a cylinder is fixedly connected to the bottom of the disk.
[0010] Preferably, the outer wall of the cylinder is threaded.
[0011] The present invention provides a compressor mounting bolt with the following advantages: Through the cooperation of the disc and the anti-detachment mechanism, the operator aligns the cylindrical end with the threaded holes on the compressor and the corresponding platform. Then, the operator presses the pull rods on both sides inward, securing the wrench around the nut and locking the two pull rods in the grooves machined on the nut. The operator then turns the wrench to screw the outer thread of the cylinder into the threaded holes of the compressor and the corresponding platform. When the crossbars on both sides align with the grooves machined on the compressor's threaded holes, the operator stops turning the handle and removes the wrench. The crossbars on both sides return to their original position using the spring force, allowing the ends of the crossbars to enter the grooves machined on the compressor's threaded holes. This grooves on the compressor's threaded holes secure the crossbars, preventing the cylinder from detaching from the corresponding platform and compressor after prolonged use, thus preventing the compressor from falling off.

[0018] The present invention will be further described below with reference to the accompanying drawings:
[0019] See attached document Figure 1-5 In this embodiment, a compressor mounting bolt includes a nut 1 and a disc 2. The nut 1, disc 2, cylinder 3, and thread 4 are the main structures of the mounting bolt. The bottom of the disc 2 is fixedly connected to the disc 2. The disc 2 is provided with an anti-detachment mechanism 5. The anti-detachment mechanism 5 includes a pull rod 501. The bottom of each pull rod 501 is fixedly connected to a crossbar 502. The inner side of each crossbar 502 is fixedly connected to a locking block 503. The outer side of each locking block 503 is provided with multiple springs 504. The spring force coefficient of the springs 504 is selected according to actual needs to meet the working requirements. The two ends of the springs 504 are fixedly connected to the disc 2 and the locking block 503 respectively.
[0020] The crossbar 502 is slidably connected to the inner walls of the left and right sides of the disc 2, the pull rod 501 is slidably connected to the inner walls of the upper sides of the disc 2, and the bottom of the disc 2 is fixedly connected to the cylinder 3, the outer wall of the cylinder 3 is machined with threads 4.
[0021] Working principle:
[0022] When using compressor mounting bolts:
[0023] The operator aligns the end of cylinder 3 with the threaded holes on the compressor and the corresponding platform. Then, the operator pushes the pull rods 501 on both sides inward, locking the wrench around the nut 1 and securing the two pull rods 501 in the grooves machined on the nut 1. The operator then turns the wrench to screw the thread 4 on the outside of cylinder 3 into the threaded holes of the compressor and the corresponding platform. When the crossbars 502 on both sides are aligned with the grooves machined on the compressor threaded holes, the operator stops turning the handle and removes the wrench. The crossbars 502 on both sides return to their original position using the elastic force of the spring 504, allowing the ends of the crossbars 502 to enter the grooves machined on the compressor threaded holes (the grooves are perpendicular to each other; for example, the compressor threaded holes are vertically distributed, while the grooves are horizontally distributed). The grooves machined on the compressor threaded holes can hold the crossbars 502 in place, thus preventing cylinder 3 from detaching from the corresponding platform and compressor after prolonged use, and preventing the compressor from falling.
[0024] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
