Example Embodiment

[0019] In order to describe the technical solution of the present invention more clearly and completely, the present invention will be further described below with reference to the accompanying drawings.

[0020] In the present invention, if there is no explanation to the contrary, the orientation words used such as "up and down" are usually for the direction shown in the drawings, or for the vertical, vertical or gravity direction. Similarly, for ease of understanding and description, "left and right" usually refers to the left and right shown in the drawings; "inner and outer" refers to the inner and outer relative to the contour of each component itself, but the above-mentioned orientation The words are not used to limit the invention.

[0021] Such as figure 1 , figure 2 As shown, the present invention provides a fixed bottom housing 100 for an LED display module, which includes a sealing groove 10 provided on the edge of the upper surface of the fixed bottom housing 100 and ...

Abstract

The invention provides a fixing bottom case of a LED display screen module. The fixing bottom case comprises a sealing groove on the surface edge of the fixing bottom case, and a fixing portion in the sealing groove. The fixing portion is used for fixation of a LED display screen module and a cabinet. The sealing groove is used to place a waterproof seal ring. The fixing portion comprises a plurality of nuts, wherein a part of the nuts are respectively arranged near middle positions of four edges of a square, and the other part of the nuts are respectively arranged on positions of four corners of the square, the positions being moved by a safe distance toward the center of the square. The centers of the nuts are connected with each other to form a polygon. The sealing groove comprises an inner side edge and an outer side edge. The shapes of the inner side edge and the outer side edge are polygons. The center line between the inner side edge and the outer side edge is overlapped with the central connecting line of the nuts. The fixing bottom case makes the nuts uniformly distributed, and waterproof effect of the LED display screen module is good, and installation is stable. The fixing bottom case uses few nuts, and reduces cost.

Description

technical field [0001] The invention relates to an LED display screen, in particular to a fixed bottom shell of an LED display screen module. Background technique [0002] At present, the module fixing method of LED fixed-mounted display screen is: fixed on the iron box or aluminum box with screws. In order to ensure the waterproof requirement after installation, generally, there are three nuts on each side of the module. The first nut placement method: place a nut in the middle of each side of the bottom case, place one nut on each of the four corners, and place a total of 8 nuts; this placement method has fixed parts on the four corners of the module, and the module is installed The operation is difficult when fixing the screw, which affects the production efficiency. The second nut placement method: place three nuts on each side of the bottom shell, that is, place one in the middle of each side, and place one on each side (between the midpoint and the end point of the s...
