[0027] The following is combined with Figure 1-Figure 4 The utility model is described in further detail.
[0028] See also Figure 1-Figure 4 The utility model provides an embodiment of a mechanical matrix wall telescopic device for an LED screen: an LED screen mechanical matrix wall telescopic device, comprising a telescopic device body 1; a connecting seat 2, the connecting seat 2 is fixed to the bottom end of the telescopic device body 1 by bolts, and the connecting seat 2 is used to support the telescopic device body 1; a moving seat 3, the moving seat 3 is sleeved inside the telescopic device body 1, the moving seat 3 extends to one end of the telescopic device body 1, and the telescopic device body 1 is used to support the moving seat 3; an electric telescopic rod 5, the electric telescopic rod 5 is connected to one end of the moving seat 3 by a coupling, and the bottom end of the electric telescopic rod 5 The electric telescopic rod 5 is fixedly connected to the inner wall of the telescopic device body 1 by bolts, and is used to horizontally move the moving seat 3; the reinforcement mechanism 4 is arranged inside the connecting seat 2, and the reinforcement mechanism 4 extends to the inside of the telescopic device body 1, and the reinforcement mechanism 4 is used to support the moving seat 3 after horizontal movement of a certain distance, thereby increasing the stability of the moving seat 3 after movement. The reinforcement mechanism 4 includes a rotating rod 401 connected to the inside of the connecting seat 2 by a bearing, and the outer wall of the rotating rod 401 is fixed with a support rod 402 by bolts, and the support rod 402 is used to support the bottom end of the moving seat 3 after moving a certain distance.
[0029] It can be further explained that the rotated support rod 402 forms a triangle shape with the movable seat 3 and the connecting seat 2. The pressure exerted on the support rod 402 is transmitted to the connecting seat 2 and the telescopic device body 1. The rotated support rod 402 thus shares the excess pressure generated by the movement of the movable seat 3, thereby ensuring the stability of the LED screen connected to the movable seat 3 during use.
[0030] See also Figure 1 , Figure 2 and Figure 4 The reinforcement mechanism 4 also includes a second spur gear 407 welded to one side of the outer wall of the rotating rod 401, the top of the second spur gear 407 is meshed with the first spur gear 406, the top of the first spur gear 406 is meshed with the rack 405, the inner wall of the first spur gear 406 is welded with a connecting column 4061, the connecting column 4061 is rotatably connected to the inner wall of the connecting seat 2 through a bearing, and the connecting column 4061 is used to support the first spur gear 406, and the rack 405 can drive the rotating rod 401 to rotate through mechanical transmission, thereby facilitating the support rod 402 to rotate and open; a groove 301 is provided at the bottom end of the moving seat 3, and a semi-cylindrical protrusion is formed at one end of the support rod 402, and the groove 301 matches the semi-cylindrical protrusion at one end of the support rod 402 The groove 301 is used to engage the semi-cylindrical protrusion at one end of the support rod 402 after rotation, thereby increasing the stability of the moving seat 3 after movement; a storage groove 201 is provided at one end of the connecting seat 2, and the storage groove 201 matches the rotation trajectory of the support rod 402. The storage groove 201 is used to store the support rod 402, thereby reducing the external space occupied by the support rod 402; a moving rod 404 is fixed to one side of the rack 405 by bolts, and the top of the moving rod 404 extends to the interior of the telescopic device body 1, and a sliding groove 101 is provided at the bottom end of the telescopic device body 1, and the sliding groove 101 matches the movement trajectory of the moving rod 404. The sliding groove 101 is used to limit the moving rod 404, and the movement of the moving rod 404 can drive the rack 405 to move.
[0031] It can be further explained that the movement of the moving rod 404 drives the rack 405 to move, the spring 4042 is squeezed by force, the movement of the rack 405 drives the first spur gear 406 to rotate counterclockwise, the rotation of the first spur gear 406 drives the second spur gear 407 to rotate clockwise, the rotation of the second spur gear 407 drives the rotating rod 401 to rotate clockwise, the rotation of the rotating rod 401 drives the support rod 402 to rotate, the rotation of the support rod 402 drives the semi-cylindrical protrusion at one end to rotate, the movement of the moving seat 3 drives the groove 301 to move at the same time, when the moving seat 3 moves to a fixed position, the semi-cylindrical protrusion at one end of the support rod 402 rotates into the groove 301 at the bottom of the moving seat 3.
[0032] See also Figure 1 , Figure 2 and Figure 4The interior of the moving rod 404 is sleeved with a limiting column 4041, and both ends of the limiting column 4041 are fixedly connected to the inner wall of the telescopic device body 1 by bolts. One end of the moving rod 404 is fixedly connected with a spring 4042, and the other end of the spring 4042 is fixedly connected to the inner wall of the telescopic device body 1. The spring 4042 is sleeved on the outside of the limiting column 4041, and the limiting column 4041 is used to support the moving rod 404, and the spring 4042 is used to provide a reset force for the moving rod 404 to move horizontally; an extrusion rod 403 is fixed to one side of the moving seat 3 by bolts, and the extrusion rod 403 is at the same height as the moving rod 404, and a moving groove matching the moving trajectory of the extrusion rod 403 is provided inside the telescopic device body 1. After the extrusion rod 403 moves and reaches one end of the moving rod 404, the moving rod 404 can be squeezed to move horizontally.
[0033] It can be further explained that the moving seat 3 moves horizontally and drives the extrusion rod 403 to move at the same time. When the extrusion rod 403 moves to one end of the moving rod 404, the extrusion rod 403 continues to move and drives the moving rod 404 to move. When the moving seat 3 resets, the spring 4042 returns to its original state and drives the support rod 402 to reset and rotate through mechanical transmission.
[0034] Working principle: When in use, the electric telescopic rod 5 works first, the output end of the electric telescopic rod 5 moves to drive the moving seat 3 to move, and the moving seat 3 moves toward one end of the telescopic device body 1, thereby driving the LED screen connected to the moving seat 3 to move;
[0035] Secondly, the moving seat 3 moves horizontally and drives the extrusion rod 403 to move at the same time. When the extrusion rod 403 moves to one end of the moving rod 404, the extrusion rod 403 continues to move and drives the moving rod 404 to move. The movement of the moving rod 404 drives the rack 405 to move. The spring 4042 is squeezed by force. The movement of the rack 405 drives the first spur gear 406 to rotate counterclockwise. The rotation of the first spur gear 406 drives the second spur gear 407 to rotate clockwise. The rotation of the second spur gear 407 drives the rotating rod 401 to rotate clockwise. The rotation of the rotating rod 401 drives the support rod 402 to rotate. The rotation of the support rod 402 drives the semi-cylindrical protrusion at one end to rotate. The movement of the moving seat 3 drives the groove 301 to move at the same time. When the moving seat 3 moves to the fixed position, the semi-cylindrical protrusion at one end of the support rod 402 rotates into the groove 301 at the bottom end of the moving seat 3. At this time, the support rod 402 supports the moving seat 3.
[0036] Finally, after the moving seat 3 moves to a certain distance, the support rod 402 rotates and engages with the groove 301 at the bottom of the moving seat 3, and the moving seat 3 transmits the pressure of the LED screen to the groove 301, and then transmits it to the support rod 402 through the groove 301. The rotated support rod 402 forms a triangle shape with the moving seat 3 and the connecting seat 2. The pressure exerted on the support rod 402 is transmitted to the connecting seat 2 and the telescopic device body 1. The rotated support rod 402 thus shares the excess pressure generated after the moving seat 3 moves, thereby ensuring the stability of the LED screen connected to the moving seat 3 during use.
