Abstract

The invention belongs to the technical field of lockers, and particularly relates to a novel locker. The novel locker comprises a fixing block; a screw rod is arranged in the fixing block, a pin is arranged at one end of the screw rod, and elastic stop rings for shafts are arranged at two ends of the pin; a guide block is arranged on the surface of the screw rod, and is provided with a flat circular through hole; a screw rod is arranged in the flat circular through hole; a square hole penetrating through a cavity is formed in the middle of the fixing block, and is used for allowing the unthreaded portion of the screw rod to pass through; waist-shaped holes are formed in two side faces of the fixing block, and are matched with the pin at the head of the screw rod in width; when the fixing block is fixed to a carrying plate bottom board through a screw, a locker body can swing round the fixing block or linearly move along the waist-shaped holes of the two side faces of the fixing block.The novel locker provided by the invention has the advantage that a carrying plate with a control module is quickly detached from or locked with an inner frame of a cabinet in an avionic electronic system according to the working principle of overrun clutches and through a specific structure.

Description

technical field [0001] The invention relates to a locking method between a tray equipped with a control module and an inner frame of a case in an avionics electronic system. To be precise, it is a quick assembly and disassembly method between the tray with the control module and the inner frame of the case, and specifically relates to a new type of locker. Background technique [0002] In the chassis of the avionics system, the tray with the control module is installed on the inner frame of the chassis. In order to deal with various emergencies, the tray carrying the control module is required to be replaced quickly and positioned firmly. If the traditional installation method of directly tightening screws or bolts and nuts is used, it is time-consuming and inconvenient, and the screws, nuts, washers, etc. are easy to fall, which will cause hidden dangers in some occasions. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned bac...
