Description

Technical Field

[0002] Large cabinet products are not convenient to ship, and there are no special standard shipping tools, which causes many inconveniences in actual work.

[0003] Existing cabinets are usually transported by traction trolleys and other devices, so the cabinets need to be installed on the trolley. Common installation methods are mostly on containers, usually with elliptical mounting holes and elliptical blocks plugged in, and the rotational dislocation of the elliptical blocks is used to form a fixed connection.

[0004] However, there are many problems in the actual installation and connection process. The cabinet body is usually close to the ground, and the traction trolley is usually equipped with rollers, which makes it difficult to adapt the installation height. It is necessary to additionally hoist and adapt the cabinet body such as the container. The installation is cumbersome and inefficient. In addition, the locking fit of the single elliptical mounting hole and the elliptical block will leave a rotation gap, so the fixing parts are not fixedly installed. During the installation and transportation process, it is very easy to fall off due to vibration, deflection, etc., and the connection stability is insufficient. Summary of the invention
