Front-back maintenance mechanism for LED display module

Abstract

The invention discloses a front-back maintenance mechanism for an LED display module. The front-back maintenance mechanism comprises a pressing plate and a lock cylinder; the lock cylinder comprises arotating rod; a side rod is fixed at one end of the peripheral side of the rotating rod; the other end of the peripheral side of the rotating rod is sleeved with an elastic piece; a platform is fixedto the position, located between the side rod and the elastic piece, of the rotating rod. The position, facing the side rod, of the outer side face of the platform is a rotating face, a penetrating hole allowing the side rod and the rotating rod to penetrate through is formed in a pressing plate, the pressing plate is located between the side rod and the platform, a limiting piece is fixed to theposition, facing the platform, of the side face of the pressing plate, and the limiting piece comprises a slope plate with the height from low to high. The front-back maintenance mechanism of the LEDdisplay module is small in structure number and convenient to maintain, front-back maintenance can be achieved at the same time, and the situation that the display effect and waterproofness are affected by the thickness and tolerance of a locked frame is avoided.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a front and rear maintenance mechanism for LED display modules. Background technique [0002] A large LED display screen is usually spliced ​​by multiple identical LED display unit boxes, and the LED display unit box generally includes an LED display module, a frame, a power supply module, and a data processing module. [0003] The application of LED displays is becoming more and more extensive, and the requirements for installation occasions are also getting higher and higher. Due to space constraints, outdoor fixed installation displays usually require front and rear maintenance of the module. In order not to affect the waterproof of the module, the conventional method is to fix the module with screws or fix it. The thickness of the frame is locked by a mechanism, which cannot be adjusted by the above method. The thickness and tolerance of the frame of the cabinet w...

[0003] The application of LED displays is becoming more and more extensive, and the requirements for installation occasions are also getting higher and higher. Due to space constraints, outdoor fixed installation displays usually require front and rear maintenance of the module. In order not to affect the waterproof of the module, the conventional method is to fix the module with screws or fix it. The thickness of the frame is locked by a mechanism. The above method cannot be adjusted. The thickness and tolerance of the box frame will affect the display effect and waterproof, and it is impossible to achieve front and rear maintenance at the same time.
