A modular LED display screen that is easy to assemble

Abstract

This utility model discloses an easy-to-assemble modular LED display screen, specifically relating to the field of display screen technology. It includes a frame and several LED display screen modules, which are evenly distributed inside the frame. Through a fixing mechanism, a handle can be twisted to rotate a torsion bar, which in turn drives a gear to move a fixed rod meshing with it upwards. After inserting a connecting block into the corresponding connecting slot, the force applied to the handle is released, allowing the torsion spring to trigger a reset movement, inserting one end of the fixed rod into a slot on the connecting block, thus fixing the LED display screen module. For disassembly, the above steps are repeated until one end of the fixed rod is removed from the slot, allowing the LED display screen module to be pulled out, thus improving work efficiency. An auxiliary component can clamp and fix the connecting block, providing initial fixation and preventing accidental removal of the connecting block during installation or disassembly, which could lead to damage to the LED display screen module.

[0024] In this example, the fixing mechanism also includes a gear 6, and there are several gears 6. Several gears 6 are equidistantly sleeved on the outside of the torsion bar 5, and several gears 6 are located between two torsion springs 7. A fixing rod 8 is provided between the gear 6 and the mounting rod 3, and one side of the fixing rod 8 is provided with several tooth grooves meshing with the gear 6. One end of the upper part of the fixing rod 8 is inserted into the slot 12 opened on the top of the connecting block 10. Guide blocks 9 are symmetrically provided on the outside of the fixing rod 8, and one end of the guide block 9 is fixedly connected to the mounting rod 3. The side wall of the fixing rod 8 is symmetrically provided with sliding grooves 13 adapted to the guide block 9. Through the fixing mechanism, the LED display module 2 can be installed and fixed conveniently and quickly, and it is also convenient to disassemble, easy to operate, and improves work efficiency, and is more practical. In this example, the auxiliary component includes a baffle 15, a reset groove 14 is symmetrically opened on the inner wall of the connection groove 11, the baffle 15 is arranged in the reset groove 14, and the baffle 15 is connected to a push rod 16 relative to the inner wall, and a retaining ring 17 and a spring 18 are sleeved on the outer side of the push rod 16, and the retaining ring 17 is fixedly connected to the inner wall of the reset groove 14, and the spring 18 is located between the baffle 15 and the retaining ring 17, and the push rod 16 is connected to a clamping block 19 at one end close to the connection block 10, and the clamping block 19 is provided with a bevel 1 at one end close to the opening of the connection groove 11, and a bevel 2 is symmetrically provided at one end of the connection block 10, and the connection block 10 can be pre-positioned by the auxiliary component.

Continuing to push can make the clamping block 19 move to the outside of the connecting block 10, and the clamping block 19 When moving into the reset groove 14, the clamping block 19 will push the push rod 16 to drive the baffle 15 to move synchronously, and then cooperate with the baffle ring 17 to make the baffle 15 stretch the spring 18. At the same time, the reverse force generated by the deformation of the spring 18 acts on the clamping block 19, so that the clamping block 19 clamps and fixes the connecting block 10, thereby playing a preliminary fixation of the LED display module 2. After multiple LED display modules 2 are installed to the corresponding positions in this way, the force applied to the handle is released, so that the torsion bar 5 is reset and rotated under the torsion of the torsion spring 7, so that the torsion bar 5 drives the gear 6 to drive the fixing rod 8 to reset and move downward, so that one end of the upper part of the fixing rod 8 is inserted into the slot 12 opened at the top of the connecting block 10, and the assembly of the LED display module 2 can be completed. The operation is convenient, the assembly efficiency can be improved, and the practicality is stronger.
