[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] The present invention provides a display instrument shockproof device, comprising a storage box 101 and a side handle 102, wherein the side handle 102 is fixedly connected to both sides of the storage box 101, and a shockproof structure is installed inside the storage box 101, wherein the shockproof structure comprises a buffer unit, a fixing unit, and a clamping unit, wherein the buffer unit is installed inside the storage box 101, the fixing unit is installed inside the storage box 101, and the clamping unit is installed inside the storage box 101;

[0038] The buffer unit includes a supporting shell 401, which is fixedly connected to the inner bottom surface of the storage box 101, and the inner part of the supporting shell 401 is movably connected to a damping rod 402, and the outer surface of the damping rod 402 is movably connected to a spring 2 403, and the top of the spring 2 403 is fixedly connected to a vertical moving block 404, and the side of the vertical moving block 404 is movably connected to a connecting plate 1 405, and the other end of the connecting plate 1 405 is movably connected to a fixed connecting block 406, and the outer surface of the fixed connecting block 406 is fixedly connected to a moving shell 410, and the top of the moving shell 410 is fixedly connected to a placement plate 411, and the side of the placement plate 411 is fixedly connected to a spring 412, and the end of the vertical moving block 404 away from the connecting plate 1 405 is movably connected It is connected to a connecting plate 2 407, and the other end of the connecting plate 2 407 is movably connected to a horizontal moving block 408, and the side of the horizontal moving block 408 is fixedly connected to a spring 3 409. By installing a buffer unit, when the storage box 101 is moved or placed, it is hit by the outside world, causing the internal structure of the storage box 101 to shake, thereby driving the vertical moving block 404 to move downward through the connecting plate 1 405, so that the spring 2 403 cooperates with the damping rod 402. At the same time, since the connecting plate 2 407 is connected to the horizontal moving block 408, the connecting plates 2 407 on both sides drive the horizontal moving blocks 408 to start stretching outward at the same time, so that the spring 3 409 is stretched, thereby achieving a buffering effect.

[0039] A horizontal moving groove is provided on the outer surface of the movable shell 410, and a vertical moving groove is provided on the outer surface of the supporting shell 401, so that the moving trajectories of the vertical moving block 404 and the horizontal moving block 408 are limited by the horizontal moving groove and the vertical moving groove, thereby preventing the horizontal moving block 408 and the vertical moving block 404 from moving offset.

[0040] The locking unit includes a fixed block 202, which is fixedly connected to the top of the storage box 101. The fixed block 202 is internally movably connected with a flip shaft 203, and the outer surface of the flip shaft 203 is connected to the top cover 201. The front of the top cover 201 is fixedly connected with a card shell 204, and the card shell 204 is internally movably connected with a card plate 205. The inner side of the card plate 205 is fixedly connected with a spring 206, and the front of the storage box 101 is fixedly connected with a card box 207. By installing the locking unit, the storage box 101 can be opened by further flipping the top cover 201 around the flip shaft 203, thereby completing the placement of the display instrument.

When the top cover 201 is flipped over and closed, the top soft pad 308 at the bottom of the top cover 201 protects the top of the display instrument, thereby preventing the display instrument from being damaged during the movement.

[0043] A protective layer is installed on the inner side of the fixing plate 303, and anti-slip grooves are provided on the inner side of the protective layer. By installing the protective layer, the fixing plate 303 is further prevented from causing damage to the outer surface of the display instrument when fixing the display instrument. At the same time, by installing the anti-slip grooves, the friction between the protective layer and the display instrument is further increased, so that the display instrument is fixed more firmly.

[0044] The outer surface of the fixed shell 301 is provided with taking slots, and there are three taking slots in total. Further, by providing the taking slots, it is convenient to place and take the display instrument, thereby improving the practicality of the device.

[0045] A threaded hole is provided on the outer surface of the fixed shell 301, and the threaded hole and the threaded rod 305 are adapted to each other, so that the threaded rod 305 is rotated by the rotating disk 306, and the threaded rod 305 is further engaged with the threaded hole inside the fixed shell 301, so that the threaded rod 305 further pushes the fixed plate 303 to move inward, thereby fixing the display instrument.

When the storage box 101 is moved or placed, it is hit by the outside world, causing the internal structure of the storage box 101 to shake, thereby driving the vertical moving block 404 to move downward through the connecting plate 1 405, so that the spring 2 403 cooperates with the damping rod 402. At the same time, since the connecting plate 2 407 is connected to the horizontal moving block 408, the connecting plates 2 407 on both sides drive the horizontal moving block 408 to start stretching outward at the same time, so that the spring 3 409 is stretched, thereby achieving a buffering effect.
