DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3A fixing device for flame-retardant light box advertising cloth comprises a hollow storage box 1, a cloth-passing hole 16 is provided on the side wall of the storage box 1, a mounting cavity 5 is provided in the top wall of the storage box 1, a rotating column 2 is rotatably connected to the storage box 1 through a bearing, one end of the rotating column 2 extends through the interior of the storage box 1, and the other end extends through the mounting cavity 5, one end of the rotating column 2 located in the mounting cavity 5 is interference-fitted with a driven gear 6, the rotating column 2 is fixedly connected with an advertising cloth 3, and the advertising cloth 3 is filled with a flame-retardant layer 4, the top wall of the storage box 1 is rotatably connected with a rotating shaft 8 through a bearing, one end of the rotating shaft 8 extends through the mounting cavity 5 and is interference-fitted with a driving gear 7, and the other end extends through the outside of the storage box 1.

[0021] A fixing block 10 is glued to one end of the advertising cloth 3 away from the rotating column 2, and locking grooves 11 are provided on the two opposite side walls of the fixing block 10. A mounting hole 12 is provided on the side wall of the storage box 1 away from the cloth passing hole 16. The storage box 1 is rotatably connected with a locking screw 13 passing through a bearing. A section of the locking screw 13 located in the mounting hole 12 is provided with threads with opposite rotation directions and is threadedly connected to two locking blocks 14. The locking block 14 is slidably connected to the inner wall of the mounting hole 12.

[0022] The size of the driving gear 7 is larger than that of the driven gear 6, so that rotating the driving gear 7 can accelerate the rotation of the driven gear 6, thereby accelerating the rotation of the rotating column 2 and allowing faster winding.

[0023] The thread lead angle of the locking screw 13 is smaller than the equivalent friction angle of the spiral pair formed by the locking screw 13 and the locking block 14, so that the threaded connection between the locking screw 13 and the locking block 14 is self-locking, avoiding shaking at the threaded connection and affecting the stability of locking.

[0024] A rotating handle 9 is welded to one end of the rotating shaft 8 located outside the storage box 1 , and an outer wall of the rotating handle 9 is engraved with anti-skid patterns.

[0025] A rotating wheel 15 is glued to one end of the locking screw 13 located outside the storage box 1, and the outer wall of the rotating wheel 15 is carved with anti-skid patterns.

[0026] In the utility model, when installing the advertising cloth 3, hold the fixing block 10, pull the advertising cloth 3 out of the storage box 1, and after it is wrapped around the light box once, the advertising cloth 3 is tightened, and then the fixing block 10 is slid into the installation hole 12, and the rotating wheel 15 is rotated to rotate the threaded rod 13. The threaded rod 13 rotates and the two locking blocks 14 move toward each other through the threaded connection, and slide into the locking groove 14 of the fixing block 10, and the fixing is completed;

[0027] When it is necessary to remove the advertising cloth 3, the rotating wheel 15 is rotated in the opposite direction to make the locking block 14 slide out of the locking groove 11, and the rotating handle 9 is rotated to rotate the rotating shaft 8, and the rotating shaft 8 drives the driving gear 7 which is in interference fit with it to rotate, so that the driven gear 6 which is meshed with the driving gear 7 rotates, and the driven gear 6 drives the rotating column 2 which is in interference fit with it to rotate, and the rotation of the rotating column 2 can roll up the advertising cloth 3. When the advertising cloth 3 is completely received in the storage box 1, the rolling is completed and it can be transported.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
