Detailed ways

As shown in Fig. 1 to Fig. 6, the installation structure of the front maintenance LED display screen provided by the utility model includes several display modules 1, and the display modules 1 are spliced and installed on the grid-like fixed bracket 2 through a fixing device. The fixing device of the present invention refers to a plurality of locking mechanisms 3 installed on the backlight surface of the display module 1 . As shown in FIG. 1 , the locking mechanism 3 includes a lock cylinder 31 , a lock tongue 32 , an outer retaining ring 33 and a fixing member 34 . The upper part of the dead bolt 32 is a right-angle hook-shaped structure, that is a shape, and the lower part is a circular shaft, so that the whole dead bolt 32 is a shape. When the display module 1 is installed on the fixed bracket 2 through the locking mechanism 3, the fixed bracket 2 is hung on the right-angled hook-shaped structure on the upper part of the deadbolt 32 through the -shaped deadbolt 32, and one end of the right-angled hook-shaped structure is pressed Tightly on one end face of the fixed bracket 2 to prevent sliding. The upper part of the lock cylinder 31 is a hollow cylinder, two spiral slide grooves (not shown in the figure) are provided on the cylindrical wall, and a small-diameter inner hexagonal lock hole 311 is provided on the lower end surface of the lower part. The lower circular shaft of the lock tongue 32 penetrates into the upper hollow cylinder of the lock cylinder 31 . The upper end of the lower part of the lock cylinder 31 is recessed inwardly, and the lower end of the lower part of the lock tongue 32 is recessed inwardly. A spring 35 is installed on the lower end surface of the dead bolt 32 . The limit pin 36 crosses the spiral chute provided by the lower part of the lock tongue 32 and the upper part of the lock cylinder 31 . When the lower part of the lock cylinder 31 is rotated, the limit pin 36 can slide along the spiral chute, thereby driving the lock tongue 32 to move up and down. The outer retaining ring 33 is located on the outer periphery of the lower part of the dead bolt 32 and the upper part of the lock core 32. Two inverted L-shaped limiting grooves 330 are provided on the wall of the outer retaining ring, and the limiting pin 36 passes through the limiting grooves 330. When the limit pin 36 slides along the spiral chute on the lock core 31 to drive the lock tongue 32 to move, it is limited in the limit groove 330 on the outer retaining ring 33 . The upper end of the outer retaining ring 33 is fixed integrally with the fixing member 34 by pressure riveting, so that the outer retaining ring 33 can remain still during the movement of the locking tongue 32 by rotating the lock core 31 . Two screw holes 340 are provided on both sides of the fixing member 34 , and the locking mechanism 3 is fixed on the display module 1 by two screws 4 . the

The backlight surface of the display module 1 is provided with an accommodating portion 10 for installing the locking mechanism 3 , and an unlocking hole 11 is opened on the display surface corresponding to the lock hole 311 of the lock cylinder 31 . On the display surface of the display module 1 , insert the hex wrench into the unlocking hole 11 , and rotate the lock cylinder 31 to tighten or open the locking mechanism 3 , thereby installing or disassembling the display module 1 . Because no screw connection is used, the diameter of the lock hole 311 can be made very small, and the unlocking hole 11 provided on the display surface of the display screen can be made very small. As far as the screen is concerned, it will not affect the appearance and display effect of the display screen, so it can be applied to high-resolution LED displays. the

In actual use, according to the size of the display module 1, multiple locking mechanisms 3 may be distributed at appropriate positions on the back of the display module 1 to ensure the stability of the installation. Simultaneously, the right-angled hook structure that is used to hang and compress the fixed bracket 2 on the dead bolt 32 should match the size of the fixed bracket 2 for specific applications, so that when the display module 1 is installed on the fixed bracket 2, it will not There will be movement or loosening. the
