Description

Technical Field

[0001] The utility model relates to the technical field of locking devices, in particular to a locking device for a sheet metal box. Background Art

[0002] Sheet metal is a processing technology. There is no complete definition of sheet metal so far. According to foreign professional journals, sheet metal can be defined as a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / compounding, folding, riveting, splicing, forming, etc. Its most notable feature is the consistent thickness of all parts. Sheet metal has the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost, and good performance in large-scale mass production. It has been widely used in electronics, communications, automotive industry, medical equipment and other fields. For example, in computer cases, mobile phones, and MP3s, sheet metal is an indispensable component. Common sheet metal cases include: power cabinets, network cabinets, server cabinets, outdoor cabinets, etc., but precisely because the sheet metal box has the characteristics of light weight, the sheet metal box cannot be effectively regulated and fixed during transportation, and bumps and scratches on the box affect the quality and appearance.

[0003] In order to solve the above technical problems, the Chinese patent with announcement number CN215286056U in the prior art discloses a locking device for a sheet metal box, including a bottom tray, a connecting rod, a folding rod and a locking mechanism. The bottom tray is connected to the connecting rod in a circumferential rotation, and the lower surface of the connecting rod is fixedly connected to a second suction cup. A fixing groove is provided at one end of the connecting rod, and one end of the connecting rod is rotatably connected to one end of the folding rod.

Once the sheet metal box is bumped during transportation and placement, the vertical rod is easily offset, and personnel are required to readjust the clamping position, which increases the workload of the staff and affects the work efficiency and practicality of the device.
