Locking connecting device, LED (Light Emitting Diode) screen box and LED display screen

Abstract

The invention provides a locking connecting device, an LED (Light Emitting Diode) screen box and an LED display screen. The locking connecting device comprises a lock hook component and a rod pin component, wherein the lock hook component comprises a lock hook base; a lock hook and a handle are arranged on the lock hook base; a gear is arranged in the handle; a plug is arranged on the lock hook base and is connected with the gear; the rod pin component comprises a rod pin base; a rod pin is arranged on the rod pin base; a fixing pin hole is arranged on the rod pin base; the lock hook component and the rod pin component are connected with the fixing pin hole through the lock hook, the rod pin and the plug which are matched with each other; the LED screen box comprises an LED box shell with an LED display component; the lock hook component and the rod pin component are respectively arranged on two opposite lateral edges of the LED box shell; and the LED display screen is formed by connecting adjacent LED screen boxes through the locking connecting device. The locking connecting device provided by the invention has the advantages of higher bearing capacity, compact and accurate connection, convenience in operation and reliable property.

Description

technical field [0001] The invention relates to a locking connection device, an LED screen box body and an LED display screen, and belongs to the technical field of mechanical structures. Background technique [0002] The structural shell of many LED display screens is spliced ​​by LED screen boxes equipped with LED display components. There are many options for connection methods, such as using pins and traditional locks, but this is not suitable for high-quality LED screen boxes. body connection. The connection of large LED screen cabinets generally requires reliable load bearing, tight and precise splicing and convenient operation. [0003] Chinese Invention Patent Publication No. 201110102759.7 discloses a lock connection device and an LED cabinet and an LED display screen using the lock. connected. The structure of the locking connection device is relatively complicated, and the transmission is not simple enough. And because the hook of the lock connection device is...

Problems solved by technology

The structure of the locking connection device is relatively complicated, and the transmission is not simple enough

And because the hook of the lock connection device is not designed with enhanced elasticity, its elastic tensile deformation is small, so that it is not enough to offset the processing error and cannot adapt to the connection gap caused by it, so its "bump includes two parts: screw and component ", the processing error must be eliminated by adjusting the screw, if the screw is too loose, the connection will be loose, and if the screw is too tight, it will be difficult to fasten, thus increasing the operating burden

In addition, the lock connection device is also prone to "the handle is not pressed in place or pops open", so a "safety mechanism" must be provided
