[0002] Refrigerated trucks, as key equipment in cold chain logistics, play an important role in transportation in industries such as food and pharmaceuticals. With the increasing demand for temperature-controlled transportation in these industries, the market share of refrigerated trucks is also increasing year by year. As the core component of the refrigeration system of refrigerated trucks, the performance of electric refrigeration compressors directly affects the refrigeration effect and energy consumption level of refrigerated trucks.

[0003] When installing a compressor, it is usually mounted on a base plate using multiple sets of bolts to ensure that the compressor remains stable during vehicle operation. In order to prevent the compressor from being damaged by external objects during use, it is usually installed in a protective frame to protect the compressor.

[0004] However, because the compressor needs to be removed from the chiller during maintenance in order to conduct a comprehensive inspection, the staff needs to use special tools to remove multiple sets of bolts before they can perform a detailed inspection of the compressor. This greatly reduces the efficiency of the staff in maintaining and inspecting the compressor, thus affecting the compressor's operating efficiency. Utility Model Content

A T-shaped block 10 is set on the mounting frame 5 corresponding to the T-shaped groove 7. The T-shaped block 10 matches the T-shaped groove 7. Through the cooperation of the T-shaped block 10 and the T-shaped groove 7, the movement direction of the mounting frame 5 can be limited.

[0027] Specifically, such as Figure 2As shown, two sets of sliding bars 11 are symmetrically arranged on the side of the mounting frame 5 near the base plate 2. The base plate 2 is provided with a sliding groove 8 corresponding to the sliding bars 11. The sliding bars 11 and the sliding groove 8 are matched. Through the cooperation of the sliding bars 11 and the sliding groove 8, the mounting frame 5 can be supported when it moves.

[0028] Specifically, such as Figure 2 As shown, the lead screw 9 is rotatably mounted in the T-groove 7, and one side of the lead screw 9 passes through the T-groove 7. A handle 6 is provided on one side of the lead screw 9, and the T-block 10 is located on the outside of the lead screw 9. The handle 6 allows the operator to easily and stably control the rotation of the lead screw 9.

[0029] Specifically, such as Figure 3 As shown, a second connecting plate 18 is fixedly installed on the compressor body 4 corresponding to the first connecting plate 16. A positioning block 19 is located on one side of the second connecting plate 18. The positioning block 19 is slidably connected to the first connecting plate 16. Through the cooperation between the positioning block 19 and the first connecting plate 16, it is convenient for the staff to check the installation position of the compressor body 4.

[0030] A fixing component is provided on the first connecting plate 16. The fixing component includes an elastic element 12 and a fixing groove 21. The fixing groove 21 is provided on the positioning block 19, and the elastic element 12 is provided on the protective frame 3. A fixing block 14 is provided on the elastic element 12. The fixing component is used to fix the compressor body 4.

[0031] Specifically, such as Figure 3 As shown, the fixing component also includes a connecting block 20 disposed on one side of the positioning block 19. A through groove 17 is provided on the first connecting plate 16 corresponding to the connecting block 20. The through groove 17 matches the connecting block 20, and the connecting block 20 passes through the positioning block 19 and extends to the outside. Through the cooperation of the through groove 17 and the connecting block 20, it is convenient for the staff to fix the position of the compressor body 4 in the future.

[0032] Specifically, such as Figure 3 As shown, a connecting groove 15 is provided on the first connecting plate 16 corresponding to the fixing block 14. The fixing block 14 and the connecting groove 15 are slidably connected. The elastic element 12 is provided between the fixing block 14 and the protective frame 3. Through the elastic force of the elastic element 12, the fixing block 14 can be driven to be firmly stuck in the fixing groove 21.

[0033] Specifically, such as Figure 3 As shown, the fixing groove 21 is set on the connecting block 20 and the fixing groove 21 passes through the connecting block 20. The fixing block 14 matches the fixing groove 21. A pull bar 13 is provided on the side of the fixing block 14 away from the first connecting plate 16. The pull bar 13 makes it easy for the operator to move the compressor body 4 and drive the fixing block 14 to detach from the fixing groove 21.

[0034] In this embodiment: the operator rotates the control handle 6, which drives the lead screw 9 to rotate, thereby moving the mounting frame 5 via the T-block 10. This facilitates the operator's maintenance of the compressor body 4 or its disassembly for repair elsewhere. The sliding strip 11 and the sliding groove 8 work together to support the mounting frame 5 during its movement, ensuring smooth movement. After the compressor body 4 is reinstalled, the fixing block 14 and the fixing groove 21 are aligned. The elastic force of the elastic element 12 allows the fixing block 14 to engage with the fixing groove 21, fixing the position of the compressor body 4 and effectively preventing it from shaking during use.

[0035] Specifically, when the compressor body 4 needs maintenance, the operator rotates the control handle 6, which in turn rotates the lead screw 9, causing the T-block 10 to move within the T-slot 7. This allows the mounting frame 5 to be removed from under the protective frame 3. During the movement of the mounting frame 5, the sliding groove 8 and sliding bar 11 provide support. At this time, the positioning block 19 slides out from the corresponding groove in the first connecting plate 16, allowing the mounting frame 5 to move the compressor body 4 out from under the protective frame 3. This facilitates the operator's transfer of the compressor body 4 to other locations for maintenance, greatly reducing the difficulty of maintenance. After maintenance, the compressor body 4 is moved back to its original position. At this time, the fixing groove 21 and the fixing block 14 are aligned. The elastic force of the elastic element 12 allows the fixing block 14 to be firmly locked in the fixing groove 21, thus fixing the compressor body 4. This ensures that the compressor body 4 remains stable during vehicle operation, allowing it to function normally.
