[0015] The utility model is further described below in conjunction with the accompanying drawings:

[0016] like Figure 1-3 As shown, the LED display screen which is tightly assembled and reliable is composed of an LED display unit 1 and a plurality of assembly slots;

[0017] The assembly groove is composed of a sliding half groove 2 and a closely abutting half groove 3, both of which are arranged on the back side of the LED display unit 1, and the sliding half grooves 2 and the closely abutting half grooves 3 on two adjacent display units 1 are abutted together to form an assembly groove;

[0018] A limit slide 5 is slidably installed in the sliding half groove 2, one end of the limit slide 5 is fixedly installed with a close plug 9, the close plug 9 is provided with a close pressure hole 10, a limit block groove 7 is provided on the limit slide 5, a limit card block 8 is slidably installed in the limit block groove 7, and the limit card block 8 is fixedly installed on the side groove wall of the sliding half groove 2;

[0019] A door frame 11 is fixedly installed on the outer groove edge of the half groove 3, and a pressing screw 15 is screwed into the door groove 13 of the door frame 11. A close pressing head 14 is fixedly installed on one end of the pressing screw 15. The close pressing head 14 is a conical head, which is pressed into the close pressing hole 10. By pressing down, the close plug 9 is clamped and pressed. Due to the setting of the conical head, it can give lateral force to the close plug 9, so that the two adjacent LED display monomers 1 are closely assembled.

[0020] In this embodiment, a vertical hole is opened at the top of the LED display unit 1, and a vertical shaft 4 is screwed on the bottom of the LED display unit 1. The vertical shaft 4 is detachable and inserted into the vertical hole. The width of the vertical hole is larger than the width of the vertical shaft 4, so that it can move within a small range, which is convenient for the close assembly operation of the strip groove.

[0021] In this embodiment, a turning knob 12 is fixedly mounted on the other end of the pressing screw 15 , and the turning knob 12 is used to rotate the pressing screw 15 to drive the pressing head 14 to press downward.

[0022] In this embodiment, a plurality of friction convex stripes 6 are provided on the outer surface of the limiting sliding strip 5 to increase the friction force thereof.

[0023] In the above structure, the assembly connection of two adjacent LED display units 1 is realized by the sliding limit slider 5. When assembling, the end of the limit slider 5 is slid into the tightly-fitting half groove 3, close to the plug to the bottom of the close-fitting pressure head 14, and at the same time, the limit card block 8 is also clamped to the side of the limit block groove 7, that is, the limit slider 5 moves to the maximum stroke, and the knob 12 is rotated to press the bottom end of the close-fitting pressure head 14 at the bottom into the close-fitting pressure hole 10. As the conical head is pressed down, the limit slider 5 is pulled into the two adjacent LED display units 1, making the assembly tight and reliable.

[0024] Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
