[0020] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is a quick locking device for the frame of an LED display screen, including a LED display screen 1 that is arranged horizontally and conflictingly arranged, and a plurality of cross bars 13 are installed horizontally inside the LED display screen 1, and both ends of the cross bars 13 are flush with the side surfaces of the LED display screen 1, one end of the cross bars 13 is provided with a slot 14, and the other end protrudes to form a plug-in column 2, and the plug-in column 2 is inserted into the slot 14 of the adjacent LED display screen 1, and a plurality of wiring grooves 6 are provided on the back of the LED display screen 1, and an operating groove 5 connected to the wiring groove 6 is provided on the middle LED display screen 1, and a winding drum 9 is provided in the operating groove 5, and a plurality of steel ropes 8 are installed on the winding drum 9, and the steel ropes 8 pass through the wiring grooves 6 at different positions respectively, and are all installed with a ring body 3, and the ring body 3 on one side is sleeved on the plug-in column 2, and the ring body 3 on the other side is installed with a stud 4 connected to the slot 14.

[0021] In this embodiment, a worm 11 is vertically provided in the operating groove 5, and a plurality of worm gear teeth 10 are installed on the outer ring of the winding disk 9 facing the LED display screen 1. The worm 11 is engaged with the worm gear teeth 10. A shaft is installed at both ends of the worm 11, and a first bearing is installed on the outside of the shaft. The outer ring of the first bearing is installed on the inner wall surface of the operating groove 5. The shaft on one side is extended outward and is installed with a rotating column 12. The cross-section of the rotating column is a hexagonal structure, so that the rotation of the rotating column can be driven by a wrench or an electric screwdriver.

[0022] In this embodiment, baffles 7 are installed in the openings at both ends of the wiring groove 6, and a channel for the ring body 3 to pass through is formed between the baffles 7 and the wiring groove 6. The steel wire rope can be limited by the channel to prevent the steel wire rope from escaping from the wiring groove.

[0023] In this embodiment, a first internal thread is provided on the inner ring surface of the ring body 3 on the other side, and a second internal thread is provided on the inner wall surface of the slot 14. The studs 4 are engaged with the first internal thread on the ring body 3 and the second internal thread on the slot 14. A hexagonal groove is provided on the outer end face of the stud 4.

[0027] After the above is completed, pull out the wire rope and extend it through the wiring groove and channel to the outside world. The ring body on the right can be put on the plug column, and the ring body on the left rotates the stud to make the stud threaded in the slot. After completion, use a wrench or electric screwdriver to rotate the rotating column. The rotation of the rotating column drives the shaft and worm, and the rotation of the worm drives the worm gear and the winding disk. The wire rope can be wound inward through the winding disk, and the ring body can be pulled inward through the wound wire rope. The ring body can pull the LED display inward, so that a row of LED displays can be spliced at one time, and the tightness between the LED displays after splicing can be ensured by extrusion.
