Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figures 1 to 6, the anti-light leakage structure of LED display described in the utility model comprises the casing 1 of rectangle and the LED display module 2 of four rectangles, described casing 1 middle part is provided with a criss-cross support, make casing 1 be formed with four installing frames 11, on the corner of each installing frame 11, be equipped with iron block 111; The edge at described LED display module 2 back sides is provided with magnet 21, and the position that this magnet 21 arranges is corresponding with the position that iron block 111 arranges; As shown in Figures 2 and 3, the coboundary of casing 1 and left hand edge are provided with convex tendon 3, lower limb and right hand edge and are provided with groove 4, for ensureing that the utility model has preferably light leakage performance, the convex tendon 3 of being located on coboundary extends along length of upper edge direction, the convex tendon 3 of being located on left hand edge extends along left hand edge length direction, the groove 4 of being located at lower limb extends along lower limb length direction, and the groove 4 of being located at right hand edge extends along right hand edge length direction.Certainly, the setting position of each convex tendon 3 and groove 4 is not limited in such scheme, only need meet convex tendon 3 and be located on the both sides that casing 1 is adjacent, and groove 4 is located on the other both sides of casing 1 and just can.
Described casing 1 is rectangle, and the coboundary of this casing 1 and the both sides of left hand edge are equipped with extended, built-in latch 5, and this latch 5 comprises interconnective latch head and latch neck, and the width of this latch head is greater than the width of latch neck; As shown in Figure 6, the lower limb of this casing 1 and the both sides of right hand edge are provided with the pin hole 6 for latch 5 is installed, described pin hole 6 is connected with rotation locking plate 7 by rotating shaft, on this rotation locking plate 7, there is deep-slotted chip breaker 71, this deep-slotted chip breaker 71 comprises wide end 711 and narrow end 712, the width of described wide end 711 is consistent with latch head width, and the width of described narrow end 712 is consistent with latch neck width; Described rotation locking plate 7 is provided with revokes 72, and described casing 1 is being provided with wide end locating slot and narrow end locating slot with rotation locking plate 7 corresponding positions; Described while revoking the wide end locating slot of 72 insertion, the wide end 711 of deep-slotted chip breaker 71 is relative with pin hole 6; Described while revoking the narrow end locating slot of 72 insertion, the narrow end 712 of deep-slotted chip breaker 71 is relative with pin hole 6.
