[0011] By adopting the above technical solution, it is convenient to wind or release the traction rope, so that the corner guard can be quickly limited.

[0012] Optionally, the size of the nut matches the size of the screw, and the screw is helically connected to the nut.

[0013] By adopting the above technical solution, it is convenient to cooperate with the screw rod and the nut, so as to drive the protective shell to move.

[0014] Optionally, a rubber pad is bonded to the edge of the protective shell, and the size of the protective shell is matched with the size of the upper end of the support frame.

[0015] By adopting the above technical solution, it is easy to ensure the fit between the protective shell and the upper end of the support frame.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] The technical solution of the present application, through the arrangement of a display screen body, a support frame, a corner guard, a traction rope, a winding drum and a rubber pad, can not only enable the winding drum to reel in the traction rope connected to the diagonal support rod, so that the traction rope can simultaneously tighten and limit the four corner guards, thus saving the trouble of limiting them one by one, but also enable the rubber pad of the protective shell to fit with the rear surface of the display screen during the rotation of the screw, thereby protecting the outer wall of the support frame from dust, avoiding dust and other stains from adhering to the bolted connections of the support frame, and further facilitating disassembly and carrying by the staff.

[0023] See also Figure 1-3 The utility model provides a technical solution: a display screen corner protection device, including a display screen body 1, a support frame 11 is detachably installed on the front side of the display screen body 1, which is convenient for supporting the display screen, corner protection pieces 2 are arranged at the four corners of the display screen body 1, and a diagonal support rod 21 is fixedly installed on the inner side of the corner protection piece 2, which is convenient for ensuring the protective effect of the corner protection piece 2, a protective shell 3 is arranged on the upper end of the support frame 11, which is convenient for protecting the upper end of the support frame 11, and a winding drum 31 is arranged in the inner cavity of the protective shell 3, and the front end of the winding drum 31 is welded A screw rod 32 is connected, a nut 33 is fixedly installed at the front end of the protective shell 3, and a positioning block 34 is rotatably installed at the rear end of the winding drum 31 through a bearing. The size of the nut 33 is adapted to the size of the screw rod 32, and the screw rod 32 and the nut 33 are spirally connected, so that the protective shell 3 can be driven to move through the cooperation between the screw rod 32 and the nut 33. A rubber pad 4 is bonded to the edge of the protective shell 3, and the size of the protective shell 3 is adapted to the size of the upper end of the support frame 11, so as to ensure the fitting effect between the protective shell 3 and the upper end of the support frame 11.

[0024] A plurality of rubber strips 22 are bonded to the outer side of the corner protection piece 2, and the rubber strips 22 are evenly spaced, so as to ensure the protective and buffering effect of the corner protection piece 2 on the corners of the display screen.

[0025] A traction rope 23 is fixedly connected to the outer side of the diagonal support rod 21 , and the other end of the traction rope 23 is wound on the outer side wall of the winding drum 31 , which is convenient for winding or releasing the traction rope 23 , so that the corner guard 2 can be quickly limited.

[0026] During installation, first place the corner guards 2 in a close fit on the four corners of the display screen, then insert the positioning blocks 34 on the protective shell 3 into the screw hole grooves of the display screen, and then rotate the screw rod 32. The screw rod 32 drives the winding drum 31 to rotate, so that the winding drum 31 winds up the traction rope 23 connected to the diagonal support rod 21, so that the traction rope 23 simultaneously tightens and limits the four corner guards 2, eliminating the trouble of limiting one by one. At the same time, during the rotation of the screw rod 32, the nut 33 on the protective shell 3 will move downward along the screw rod 32, so that the rubber pad 4 of the protective shell 3 is in contact with the rear surface of the display screen, thereby protecting the outer wall of the support frame 11 from dust, avoiding dust and other stains from adhering to the bolt connection of the support frame 11, and further facilitating the staff to disassemble and carry.
