Description

Technical Field

[0001] The utility model relates to the technical field of cabinet locking, in particular to a locking device. Background Art

[0002] A cabinet is a stand-alone or self-supporting housing for electrical or electronic equipment. Cabinets are generally equipped with doors, removable or non-removable side panels and back panels. Cabinets are an indispensable component of electrical equipment and are the carrier of electrical control equipment. They are generally made of cold-rolled steel plates or alloys. They can provide protection for the stored equipment such as waterproofing, dustproofing, and electromagnetic interference. Cabinets are generally divided into server cabinets, network cabinets, console cabinets, etc. Many people regard cabinets as cabinets for IT equipment. Cabinets are cabinets, but not only that. For the computer itself, cabinets also play an important auxiliary role with UPS power supply. A good cabinet means ensuring that the computer can run in a good environment. Therefore, the role played by the cabinet is equally important. The cabinet systematically solves the problems of high-density heat dissipation, large-scale cable attachment and management, large-capacity power distribution, and full compatibility with rack-mounted equipment from different manufacturers in computer applications, so that data centers can operate in a highly stable environment. Cabinets of various styles can be seen in major computer rooms. With the continuous breakthroughs in the computer industry, the functions reflected by cabinets are becoming more and more important. Cabinets are generally used in network wiring rooms, floor wiring rooms, central computer rooms, data computer rooms, control centers, monitoring rooms, monitoring centers, etc. The standard width of the cabinet is usually 19 inches.

[0003] Generally, the chassis is installed in the cabinet by fastening it with the captive bolts on the plug-in box panel and the cabinet nuts. The locating pin side of the plug-in box is not fastened to the cabinet. In a bumpy working environment, such as when moving in a vehicle or an airborne cabin, the plug-in box in the cabinet will "swing its tail", causing the plug-in box to be subjected to high-frequency vibration and impact up, down, left, and right. The captive bolts on the plug-in box panel will also fail soon. The plug-in box in the cabinet and the chassis will face the risk of falling and being damaged. Conventional plug-in box locks on the market are large in size due to structural limitations, and require a large space for operation. Utility Model Content
