Description

Technical Field

[0001] The utility model relates to the technical field of cabinets in vehicle-mounted square cabins or vans, in particular to a vibration isolation device for vehicle-mounted cabinets. Background Art

[0002] Cabinets are installed in large quantities in vehicle-mounted cubicles or vans to hold various types of sophisticated electronic vehicle-mounted equipment such as equipment boxes, vehicle-mounted computers, shelf displays, and integrated power supplies. As vehicle-mounted cubicles and vans often need to travel on bumpy and uneven field roads, the vibration of the vehicle-mounted equipment is very large. Vibration isolators need to be installed on the bottom and sides of the cabinet to absorb the vibration energy of the vehicle-mounted cubicle or van to the maximum extent, in order to ensure that the vehicle-mounted equipment can work normally and improve the reliability of the cabinet.

[0003] The existing patent with announcement number CN217207493U proposes a vehicle-mounted cabinet vibration isolation device, which is provided with a vertical vibration isolation mechanism and a transverse vibration isolation mechanism. The vertical vibration isolation mechanism includes a vibration isolation platform, a base and a plurality of vertical vibration isolators, and a group of four vertical vibration isolators are supported between the vibration isolation platform and the base. The transverse vibration isolation mechanism includes a connecting rectangular steel pipe, a groove-shaped member, a back plate and a plurality of back frame vibration isolators. The connecting rectangular steel pipe is fixedly connected to the embedded iron in the compartment bulkhead. A group of two back frame vibration isolators are spaced between the two ends of the groove-shaped member and the connecting rectangular steel pipe. The back plate is located in the groove-shaped member and is fixedly connected to one side of the back frame vibration isolator. The center of the other side of the back frame vibration isolator is fixed to one side of the connecting rectangular steel pipe by a square head bolt.

[0004] Although the above-mentioned vibration isolation device improves the vertical and lateral vibration isolation effects of the cabinet and is easy and quick to use, it does not have the function of quickly disassembling the vehicle-mounted cabinet. It is often fixed by bolts, and the disassembly is relatively cumbersome and inconvenient. To address the above problems, we propose a vehicle-mounted cabinet vibration isolation device for improvement and upgrading. Utility Model Content
