Description

Technical Field

[0001] This utility model belongs to the field of refrigeration application technology, specifically relating to shock-absorbing components for installing refrigeration units in refrigerated trucks. Background Technology

[0002] Currently, cold chain delivery mainly uses refrigerated trucks or electric tricycles equipped with insulated boxes, or directly packages goods in insulated boxes and adds ice packs and ice boxes for transportation with ordinary goods. The refrigeration and freezing equipment used in conjunction with refrigerated trucks mainly includes mechanical refrigeration units and cold storage systems.

[0003] The refrigeration unit of a refrigerated truck mainly consists of a compressor, condenser, evaporator, and expansion valve. The working principle of the refrigeration unit is that it relies on external power to drive the compressor, causing the refrigerant to circulate continuously within the system. When the refrigerant flows through the evaporator, it absorbs heat from the compartment through evaporation, and then releases the heat through the condenser outside the compartment. This continuous cycle achieves a continuous cooling effect.

[0004] When refrigeration units are installed in the refrigerated truck compartment, it is necessary to ensure that the vibration amplitude is controllable during transportation (within the appropriate vibration range), and that the refrigeration unit is stable and reliable to ensure safe refrigeration circulation within the compartment. Therefore, the installation of the refrigeration unit requires addressing the vibration issue to reduce the vibration amplitude and maintain it within the corresponding controllable range.

[0005] Therefore, based on the above problems, this utility model provides a shock-absorbing component for installing refrigeration units in refrigerated trucks. Utility Model Content

[0006] Purpose of the utility model: The purpose of this utility model is to provide a shock-absorbing component for the installation of refrigeration units in refrigerated trucks, thereby solving the technical problems existing in the installation of refrigeration units in the background art.

[0010] In this technical solution, the outer limiting guide sleeve, the upper metal limiting pad, and the lower metal limiting pad have the same diameter, and the inner limiting guide sleeve and the outer limiting guide sleeve have the same height.

[0011] Compared with the prior art, the beneficial effects of the shock-absorbing component for installing refrigeration units in refrigerated trucks of this utility model are as follows: 1.

[0016] Example 1 like Figure 1 and Figure 2 The image shows shock absorbers for installing refrigeration units in refrigerated trucks. Includes screw 10 and nut 12. The screw 10 is fitted with an upper metal pad 13 and a lower metal pad 14. On the screw 10, and between the upper metal pad 13 and the lower metal pad 14, there are upper perforated steel wire rods 15 and lower perforated steel wire rods 16. Among them, the upper metal pad 13, the lower metal pad 14, the upper perforated steel wire column 15, and the lower perforated steel wire column 16 have the same diameter.

[0017] The working principle or structural principle is as follows: (1) First, the upper metal pad 13 and the upper perforated steel wire column 15 are successively mounted on the screw 10; (2) Then, the refrigeration unit connecting frame 200 is mounted on the screw 10; (3) Finally, the lower perforated steel wire column 16 and the lower metal pad 14 are successively mounted on the screw 10, and the carriage connecting frame 200 is mounted on the tail end of the screw 10. Then, the carriage connecting frame 200 is locked with the nut 12, thus completing the overall assembly.

[0018] Example 2 Based on Embodiment 1, the shock absorber for installing the refrigeration unit of the refrigeration truck also includes an upper metal limiting pad 18 and a lower metal limiting pad 19, which are fitted on the screw 10 and located in the cavity formed by the upper metal pad 13, the lower metal pad 14, the upper perforated steel wire column 15, and the lower perforated steel wire column 16, and an inner limiting guide sleeve 11, which is fitted on the screw 10 and located between the upper metal limiting pad 18 and the lower metal limiting pad 19.

[0019] The upper metal limiting pad 18 and the lower metal limiting pad 19 are used to limit the upper perforated steel wire column 15 and the lower perforated steel wire column 16, respectively, to prevent large vibration-damping deformation. The inner limiting guide sleeve 11 is used to provide corresponding vertical support for the upper metal limiting pad 18 and the lower metal limiting pad 19. The overall purpose of the above is to achieve controllable vibration amplitude after assembly and to prevent large vertical vibration.

[0021] The overall purpose of the above is to prevent large-scale horizontal vibrations after assembly.

[0022] In addition, preferably the outer limiting guide sleeve 17, the upper metal limiting pad 18, and the lower metal limiting pad 19 have the same diameter, and the inner limiting guide sleeve 11 and the outer limiting guide sleeve 17 have the same height. This structural design ensures that the center of gravity is stable during the shock absorption process after assembly, and achieves a safe and stable shock absorption function.
