According to the LED display screen, the protective cover 12 is arranged, and the protective cover 12 is covered on the opening 111 and the idle interface, so that the phenomenon that dust and moisture are easily brought into the LED display screen to damage the idle interface exposed outside is avoided.

In the present embodiment, the magnet 16 is provided at the edge of the shield cover 12, and the shield cover 12 is attached to the bottom case 11 by the magnet 16, thereby covering the opening 111. Thus, the protective cover 12 can be detachably connected, and the protective cover 12 can be conveniently taken down and covered.

When the LED display screen is used outdoors, severe weather such as storm and the like can be frequently encountered, rainwater is not prevented from entering the interface, in the embodiment, the waterproof ring 13 is arranged on the edge ring of the opening 111, and the waterproof effect of the interface is enhanced.

Referring to fig. 2, in the present embodiment, the edge of the opening 111 is provided with a groove 112 for accommodating the waterproof ring 13. In this way, the waterproof ring 13 can be fixed in the groove 112.

Referring to fig. 2, in order to further fix the waterproof ring 13, in the present embodiment, a fixing member 14 for fixing the waterproof ring 13 is further included. The fixing member 14 includes a fixing portion 141 and an engaging portion 142 away from the fixing portion 141, the engaging portion 142 is elastically deformed by an external force, the fixing portion 141 abuts the waterproof ring 13 on the other end of the waterproof ring 13, and the engaging portion 142 is engaged with an edge of the opening 111. Therefore, the waterproof ring 13 does not need to be assembled in a threaded connection manner like the conventional method, and the assembly is more convenient.

In this embodiment, a clamping block is disposed at an end of the clamping portion 142 away from the fixing portion 141, and the clamping block is provided with an arc-shaped transition surface.

Referring to fig. 2, specifically, during installation, the waterproof ring 13 is placed in the groove 112, and then the side of the fixing member 14 provided with the engaging portion 142 is pressed towards the opening 111, at this time, the engaging portion 142 is pressed and deformed by the inner wall of the opening 111, and when the clamping block passes through the opening 111, the engaging portion 142 is elastically reset, and the clamping block is clamped with the edge of the clamping hole. At the same time, the fixing portion 141 is also abutted against one end of the waterproof ring 13. Thus, the fixing member 14 fixes the waterproof ring 13.

In the present embodiment, the edge of the bottom case 11 is provided with a magnet 16, and the bottom case 11 is fixed to the LED die-casting case 2 by the magnet 16. The LED display module 1 can be directly installed on the LED die-casting box body 2 in the front more conveniently, and the magnet 16 is removed from the adsorption connection during disassembly, so that the operation is simple.

Referring to fig. 3 and 4, in general, during the installation process, the LED display module 1 is installed on one side of the LED die-casting box 2, and then the power control box is installed on the LED die-casting box 2 from another direction and is plugged with the interface of the LED display module 1. In the plugging process, the power supply control box can generate pressure towards the LED display module 1, and if the magnetic attraction of the LED display module 1 is insufficient at the moment, the LED display module is easy to separate from the LED die-casting box body 2. To avoid this, in the present embodiment, the LED die-cast case 2 is provided with a convex portion 21, and the LED display module 1 is further provided with a locking member 15. The retaining member 15 is rotatably connected to one side of the LED display module 1 facing the LED die-casting case 2, one end of the retaining member 15 is provided with a retaining portion 151, and the retaining member 15 rotates to a preset angle, where the retaining portion 151 abuts against the protruding portion 21. Thereby, the LED display module 1 is further strengthened to be connected with the LED die-casting case 2 by the locking member 15.

When the locking member 15 is used, the locking portion 151 is not perfectly abutted against the convex portion 21 in order to prevent the rotation angle of the locking member 15 from being too large, and in the present embodiment, the convex portion 21 is provided with the magnet 16, and the locking portion 151 is abutted against the convex portion 21 by the attraction of the magnet 16. Thus, when the rotation angle is too small or too large, the magnet 16 can actively attract the locking portion 151 to the protrusion 21 by magnetic attraction, so as to ensure that the locking portion 151 is completely attached to the protrusion 21, thereby improving the locking effect of the locking member 15, and without manually judging whether the locking member 15 has been rotated to an optimal angle.

Referring to fig. 5, in the present embodiment, the locking member 15 further includes a rotating portion 152 far away from one end of the locking portion 151, the bottom shell 11 is provided with a receiving groove 113 for receiving the rotating portion 152, a limiting groove 1521 is partially formed along a circumferential position of the rotating portion 152, a limiting block 1131 matched with the limiting groove 1521 is disposed inside the receiving groove 113, and the limiting groove 1521 and the limiting block 1131 are used for limiting a rotation angle of the locking member 15. Specifically, when the locking member 15 rotates to completely attach the locking portion 151 to the protrusion 21, the stopper 1131 abuts against one end of the stopper groove 1521; when the locking member 15 rotates to just disengage the locking portion 151 from the protrusion 21, the stopper 1131 abuts against the other end of the stopper groove 1521. Therefore, under the cooperation of the limiting groove 1521 and the limiting block 1131, the locking member 15 cannot rotate 360, and cannot continue to rotate when just rotating to a locked or unlocked state, so that the user experience of the locking member 15 is better when the locking member 15 is used, and similarly, whether the locking member 15 has rotated to an optimal angle or not is not required to be judged by people.

The second aspect of the invention also relates to a LED display screen, an LED display module 1 according to any one of the above.

In the invention, the LED display module 1 is provided with two interfaces, and when only one of the interfaces is required to be connected with the data transmission module in the power supply control box, the other interface is in an idle state. Therefore, the protection cover 12 is arranged, and the protection cover 12 is covered on the opening 111 and the idle interface, so that the problem that dust and moisture are easily brought into the LED display screen to cause damage due to the idle interface and the exposed interface is avoided.
