Remote controller internal mainboard self-locking device

Abstract

The invention discloses a remote controller internal mainboard self-locking device, and particularly relates to the technical field of remote controllers, the remote controller internal mainboard self-locking device comprises a shell, the upper surface of the shell is in lap joint with the lower surface of a cover plate, two first grooves are formed in the upper surface of the shell, and first piston assemblies are arranged on the inner walls of the first grooves. By arranging a clamping plate, a fourth elastic assembly, a connecting air bag, a second piston frame, a second contact plate, a pin shaft, a fixing block, a guide rod and a guide sleeve, the mainboard is limited, meanwhile, a supporting column makes contact with the mainboard, the mainboard is prevented from shaking horizontally and vertically at will, and when the second contact plate is pressed, the mainboard is prevented from shaking horizontally and vertically. At the moment, air in the connecting air bag is sucked and transferred into the second piston frame, the connecting air bag shrinks to control the clamping plate to rotate away from the main plate, the main plate is taken out upwards, the locking process of the main plate is convenient and fast, it is guaranteed that stress at multiple positions is balanced, operation is simple, and meanwhile damage caused by uneven stress is not likely to occur.

Description

technical field [0001] The present invention relates to the technical field of remote controllers, and more particularly, to a self-locking device for an internal mainboard of a remote controller. Background technique [0002] When the mainboard of the remote control is assembled, it is partly fixed by screwing. Multiple screw holes need to correspond to the holes on the surface of the mainboard, and then rotate multiple screws respectively. While the operation is cumbersome, the degree of screw tightening may be different. This leads to uneven stress on the main board and even cracks. At the same time, the placement process of the main board needs to be fine-tuned many times, which makes the assembly and disassembly process of the main board obviously not convenient and fast. Therefore, a self-locking device for the main board inside the remote control is needed to solve the above problems. . SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defe...

Problems solved by technology

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a self-locking device for the main board inside the remote control. The technical problem to be solved by the present invention is: when the main board in the remote control is assembled, part of it is fixed by screwing. Each screw hole needs to correspond to the holes on the surface of the main board, and then rotate multiple screws respectively. While the operation is cumbersome, different screw tightening degrees may cause uneven stress on the main board, or even cracks. At the same time, the placement process of the main board Multiple fine-tuning is required, which makes the assembly and disassembly process of the main board obviously not convenient and quick.
