[0026] Referring to Figure 2 - Figure 3 , an embodiment of the present utility model provides a side plug lock structure 200, which includes a first plug seat 210, a second plug seat 220 and a plug body 230. A first plug hole 211 is provided on the first plug seat 210, a second plug hole 221 is provided on the second plug seat 220, the first plug seat 210 and the second plug seat 220 are arranged opposite to each other, the plug body 230 is fixedly connected to the second plug seat 220, a movable plug rod 231 is provided on the plug body 230, and the plug rod 231 movably penetrates through the second plug hole and can extend into the first plug hole 211, so as to realize plug connection.

[0027] Specifically, referring to Figure 4 , the plug body 230 further includes a housing 232, a lock disk 234 and a lock catch 235 arranged inside the housing 232. A knob 233 is rotatably connected to the housing 232. The knob 233 includes a head 2331 and a rod portion 2332. A connection hole is provided on the housing 232, and the rod portion 2332 is rotatably connected in the connection hole. A strip hole 2341 is provided on the lock disk 234, and the rod portion 2332 penetrates through the strip hole 2341 and is fixedly connected to the lock catch 235, so that when the head 2331 of the knob 233 is rotated, the lock catch 235 can be driven to rotate.

[0028] A sliding space is formed between the latch 235 and the outer shell 232, and the lock plate 234 is slidably disposed in the sliding space. In addition, an elastic member is connected between the lock plate 234 and the latch 235. The elastic member is used to drive the lock plate 234 to move when the latch 235 rotates. That is, when the knob 233 is turned to drive the latch 235 to rotate, under the action of the elastic member, the lock plate 234 is driven to move left and right. When the lock plate 234 moves left and right, the rod portion 2332 abuts against the left and right ends of the strip-shaped hole 2341 respectively, thereby limiting the maximum positions of the left and right movement of the lock plate 234, and the elastic force of the elastic member causes the lock plate 234 to stay at the maximum positions at the left and right ends.

[0029] Further, a latch rod 231 is connected to one side of the lock plate 234 along its sliding direction. The latch rod 231 penetrates through the outer shell 232 and is inserted into the second latch hole 221 and the first latch hole 211. That is, the latch rod 231 moves with the lock plate 234. When the lock plate 234 moves to the maximum positions at the left and right ends, the latch rod 231 extends into or leaves the first latch hole 211 respectively, realizing the unlocking or locking of the side latch lock structure 200.

[0030] Specifically, a lug 2344 is provided on one side of the lock plate 234. A clamping groove is provided at one end of the latch rod 231. The lug 2344 is clamped in the clamping groove, and a first pin hole 238 is provided on the lug 2344. A second pin hole 238 is provided on the latch rod 231. A pin 238 is used to rivet into the first pin hole 238 and the second pin hole 238 to realize the fixed connection between the lock plate 234 and the latch rod 231.

[0031] In this embodiment, referring to Figure 4 and Figure 6 A Y-shaped gear hole 2342 is provided on the lock plate 234. The gear hole 2342 has a first gear and a second gear. A block 2351 is provided on the latch 235. The block 2351 is disposed in the gear hole 2342. When the lock plate 234 moves to the maximum positions at the left and right ends, the block 2351 moves to the first gear and the second gear respectively. Combining with the elastic action of the elastic member, the lock plate 234 is stably maintained at these two positions, that is, the side latch lock structure 200 is stably in the unlocked or locked state.

[0032] In this embodiment, referring to Figure 4 and Figure 6, the elastic member includes a circlip 239. A first protrusion 2343 is provided on the lock plate 234, and a second protrusion 2352 is provided on the lock catch 235. Necking portions are provided on both the first protrusion 2343 and the second protrusion 2352. Clamping rings are provided at both ends of the circlip 239, and the clamping rings are clamped to the necking portions to realize the installation of the circlip 239. The middle part of the circlip 239 has a circular bending structure to provide an elastic action point.

[0033] In this embodiment, referring to Figure 4 and Figure 5 , the rod portion 2332 and the lock catch 235 are detachably connected by a locking member. Specifically, the locking member includes a locking screw 236. A locking hole is provided on the lock catch 235, and a threaded hole is provided on the rod portion 2332. The locking screw 236 passes through the locking hole and is threadedly connected to the threaded hole to lock the lock catch 235 on the rod portion 2332. A gasket 237 is provided on the locking screw 236, and the gasket 237 is arranged between the head 2331 of the locking screw 236 and the lock catch 235 to improve the locking effect through the gasket 237 and avoid damage to the lock catch 235.

[0034] In this embodiment, referring to Figure 5 , an extension portion is provided on the inner side wall of the housing 232. A strengthening hole is provided along the axis of the extension portion, and the strengthening hole is communicated with the connection hole. The rod portion 2332 is in clearance fit with the strengthening hole, and a sliding surface is provided at the end of the extension portion. The gap between the sliding surface and the surface of the lock catch 235 forms the sliding space to limit the left - right movement of the lock plate 234 in the horizontal direction.

[0035] Referring to Figure 1 and Figure 2 , an embodiment of the present utility model provides an LED display module, which includes at least two LED displays 100. Adjacent two LED displays 100 are connected by the side - plug - pin lock structure 200. The first plug - pin seat 210 is fixedly installed on one of the LED displays 100, and the second plug - pin seat 220 and the plug - pin body 230 are fixedly installed on the other LED display 100. When the plug - pin rod 231 on the plug - pin body 230 passes through the second plug - pin seat 220 and inserts into the first plug - pin hole 211 of the first plug - pin seat 210 to realize the connection of the two LED displays 100, the plug - pin rod 231 plays a supporting role for the LED display 100, thereby avoiding the problem of the front - back height difference in the middle of the box body caused by the self - weight of the LED display 100, and thus ensuring the display effect of the LED display module.
