A locking mechanism for an electronic equipment chassis cover and its application method

Abstract

The invention relates to a locking mechanism of an electronic device equipment case cover plate and a using method thereof. The locking mechanism of the cover plate is provided with a lock tongue assembly, a guide pin, a steel wire drive assembly and a locking assembly, wherein the lock tongue assembly and the guide pin correspond to a locking throat and a rebounder on the sidewall of an case bodyrespectively. Various lock tongues are connected in series to the U-shaped block of a locking block by a master steel wire, a transmission steel wire and a branch steel wire. A safety lock controls aslide block, and moves the slide block to drive the locking pin of a linkage into and out of the locking hole of the U-shaped block. When the cover plate is installed, the guide pin is aligned with the rebounder, the cover plate is pressed, and the lock tongues are inserted into the lock throat to be locked. When the cover plate is uninstalled, the safety lock is unlocked, the slide block is moved, the locking block is unlocked, a handle is rotated upward to be horizontal and then is pull outwards, the locking block is moved outwards, the mater steel wire, the transmission steel wire, and thebranch steel wire are pulled to synchronously drive the lock tongues connected in series to exit the lock throat, the rebounder opens the top plate, and the cover plate is removed. The locking mechanism does not need any tool, can quickly install and uninstall the cover plate of the equipment case, has good electromagnetic shielding performance, and also has a safety lock.

Description

technical field [0001] The invention relates to a case structure of an electronic device, in particular to a locking mechanism for a cover plate of the case of an electronic device and a using method thereof. Background technique [0002] The chassis of existing electronic equipment is required to be airtight and have an electromagnetic shielding function. [0003] At present, many covers of electronic equipment cases are assembled through card slots. The installation and disassembly are relatively simple, but the gap between the cover and the box is large, the electromagnetic shielding effect is not good, and electromagnetic leakage interferes with the normal operation of the equipment. [0004] There are also many case covers that are fastened and installed with screws, which have the function of electromagnetic shielding. However, the assembly of a large number of screws is cumbersome, which is not conducive to quick disassembly and assembly, and the assembly efficiency ...
