As shown in fig. 1 to 3, an embodiment of the present application discloses a self-moving bead protection device 100, which includes a base 110, a protection plate 120, a sliding seat 130, a limiting member 140, a magnet 150, and a first elastic member 160, wherein an inclined sliding groove 111 is disposed on the base 110; the sliding seat 130 is connected with the base 110 and can slide along the sliding groove 111; the sliding seat 130 is fixedly connected with the protection plate 120;
the base 110 is provided with an accommodating cavity 112, and one end of the accommodating cavity 112 is communicated with the outside; the limiting member 140 is at least partially accommodated in the accommodating cavity 112; the first elastic member 160 is disposed inside the accommodating cavity 112, one end of the first elastic member abuts against the bottom wall of the accommodating cavity 112, and the other end abuts against the limiting member 140;
a protection plate 120, which is provided with a limit matching structure 121 corresponding to the limiting member 140; the limiting member 140, under the action of the first elastic member 160, at least partially protrudes out of the accommodating cavity 112, abuts against the limiting matching structure 121, and locks the position of the protection plate 120;
the magnet 150 is fixedly connected with the limiting member 140; when the magnet 150 is acted by the repulsive magnetic force, the limiting member 140 is driven to move towards the bottom of the accommodating cavity 112, the limiting member 140 is separated from the limiting matching structure 121, and the position locking of the protection plate 120 is released;
when the position lock of the protection plate 120 is released, the sliding seat 130 is forced to slide along the sliding groove 111 on the base 110, and the protection plate 120 follows the movement of the sliding seat 130 to switch between the first position and the second position.
The base 110 is provided with an inclined slide groove 111. As shown in fig. 6, in practical application, the lamp bead protection device 100 may be mounted on a side surface of a frame 200 of an LED box, and an LED lamp panel 300 is mounted on the frame 200. The inclined direction of the sliding groove 111 may specifically be, the farther away from the LED lamp panel 300, the farther away from the side surface of the frame 200, the closer to the inside of the frame 200.
The sliding seat 130 is slidably connected to the base 110, and the sliding seat 130 can slide along the sliding groove 111. The uppermost position of the sliding seat 130 is restricted by the sliding groove 111, that is, the position (including the horizontal position and the longitudinal position) of the protection plate 120 fixedly connected to the sliding seat 130 is also restricted by the sliding groove 111. When the sliding seats 130 are located at both ends of the sliding chute 111, the protection plate 120 is located at the first position and the second position, respectively.
For convenience of description, the positions of the sliding groove 111 and the protection plate 120 are explained by taking the direction given in fig. 6 as an example.
As shown in fig. 6, the lamp bead protection device 100 is disposed on the upper side of the frame 200, and the LED lamp panel 300 is mounted on the left end face of the frame 200. The chute 111 is inclined downward from left to right. The left side of the chute 111 is the top end and the right side is the bottom end.

A magnet 150 may be fixedly provided on the stopper 140. When in actual use, the magnetism of the magnets of the lamp bead protection devices correspondingly arranged on the two adjacent LED boxes is the same. Based on the principle that like poles repel each other, a repulsive magnetic force is generated between the two poles. Therefore, the magnet 150 in fig. 6 receives a downward magnetic force, and when the magnet on the adjacent LED box is close enough (at this time, the bead protection devices on the adjacent LED box are not yet abutted against each other), the magnetic force received by the magnet 150 is greater than the pushing force provided by the first elastic member 160, so as to push the limiting member 140 to move towards the bottom of the accommodating cavity 112. As shown in fig. 7 and 8, during the moving process, the limiting member 140 is separated from the limiting engagement structure 121, so as to unlock the protection plate 120. As shown in fig. 9 and 10, when the bead protection devices on the adjacent LED boxes are further closed and abutted against each other, the bead protection devices interact with each other, so that the protection plate 120 moves downward, and the protection plate 120 moves in an inclined downward direction until the sliding seat 130 is located at the bottom end of the right side of the sliding groove 111 when guided by the sliding groove 111. At this time, the protection plate 120 is located at the second position, and the protection plate 120 is not protruded from the LED lamp panel 300 any more, but is accommodated on the side surface of the frame 200. The protection plate 120 is no longer between the LED lamp panels 300, and the splicing effect of adjacent LED boxes is not affected.
