Embodiment
In order to make the object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated. It is to be understood that specific embodiment described herein is only in order to explain the present invention, it is not intended to limit the present invention.
Fig. 1-Fig. 6 shows an embodiment of a kind of anti-loose LED display casing of the present invention: a kind of anti-loose LED display casing, comprise LED display casing and it is arranged on LED display casing fast lock behind, described fast lock is made up of dead bolt 2, transmission shaft 3, mount pad 4, lock block 5, limited block 6 and extension spring 7, on movable part that wherein mount pad 4 and lock block 5 are arranged on LED display casing respectively and mounting block, described mount pad 4 is provided with transmission hole 41 and fixing post 42, and described lock block 5 is provided with the projection 51 suitable with dead bolt 2; Described limited block 6 is integrally formed shaping and become by mutual vertically disposed extension spring fixed plate 61 with rotation collar 62, extension spring fixed plate 61 is provided with extension spring pickup groove 63, the outer ring of described rotation collar 62 is positioned at extension spring fixed plate 61 both sides place be provided with back to two spacing hooks 64, described two spacing hooks 64 contact with described stop block 43 when limited block 6 rotates with transmission shaft 3 restriction rotate;
Described transmission shaft 3 passes from the transmission hole of mount pad 4, its end being positioned at outside mount pad 4 is fixedly connected with dead bolt 2 by retaining screw 1, its end being positioned at mount pad 4 by the rotation collar 62 of position-limiting ear groove and limited block 6 mutually card buckle and realize coaxial synchronous axial system, one end of described extension spring 7 is connected on the fixing post 42 of mount pad 4, the other end is connected with the extension spring fixed plate 61 of limited block 6 by extension spring pickup groove 63, and extension spring 7 provides the pulling force to fixing post 42 direction for limited block 6;
Described limited block 6, transmission shaft 3 and dead bolt 2 form tumbler, and the edge in described transmission hole 41 is provided with stop block 43, and stop block 43 is buckled on projection 51 limit tumbler for dead bolt 2 and is rotated further.
