Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of suspension support, for example, to a suspension type mounting structure for a PLC control cabinet. BACKGROUND

[0002] The description in this section is only provided to relate to the background of the present disclosure and does not constitute prior art.

[0003] As one of the core devices in the field of industrial automation, the size and mounting method of the programmable logic controller (PLC) control cabinet differ according to different application scenarios. Large PLC control cabinets are usually designed as vertical structures and are directly placed on flat and stable ground to meet the requirements for heat dissipation, maintenance and operation space. In contrast, small PLC control cabinets are more common in situations where space needs to be saved or in specific installation environments due to their small size, light weight and flexibility in deployment.

[0004] To ensure the safe operation of small PLC control cabinets and avoid potential risks such as flooding and collision, the industry generally adopts a suspension installation method. This installation method not only effectively utilizes vertical space, but also improves the safety protection level of the equipment to a certain extent. However, the existing suspension installation technology has several significant shortcomings.

[0005] Specifically, the current mainstream suspension installation method relies on expansion screws to fix the control cabinet to the wall. This process usually involves the following steps: first, at least two operators are needed, one to hold the control cabinet against the wall and keep it stable, and the other to mark the position of the fixing hole; then, use a drill to punch holes at the marked position; finally, install expansion screws and tighten the control cabinet. This process not only consumes time and effort, but also requires a high demand for manpower, increasing installation costs and safety risks. SUMMARY
