Description

Technical Field

[0001] The utility model relates to the technical field related to backpack boxes, and in particular to an anti-disassembly device for a backpack box. Background Art

[0002] A backpack box generally refers to a box with a hard shell and shoulder straps. Although existing backpack boxes are made of hard materials, compared with fabric backpacks, they can better protect the items placed therein and are convenient for long-distance travel.

[0003] Existing backpacks usually use zippers and locks. Although it is convenient to take out the items at any time, if you are not careful after carrying it, someone can still open the zipper and steal the items. It is relatively easy to disassemble, but it is unsafe to use. Utility Model Content

[0012] Preferably, paddles are fixedly connected to the two groups of baffles.

[0013] The beneficial effects of the utility model are:

[0014] 1. Through the coordination between the frame, stud screw, curved rod, rod body and box body, the stud screw is used to drive two sets of curved rods to fit with the box body, so that the two parts of the box body can be opened and locked, making it inconvenient to open the box body. The stud screw is used to cover the back by the back straps of the frame body, so that the person behind can not open the box body, and the box body can be prevented from being dismantled at the back, which is safe to use;

[0015] 2. By cooperating between the frame, the opening, the block and the baffle, the block at the box is fitted with the opening, and the baffle is rotated into the arc groove in the opening, so that the frame and the box can be installed, and can be disassembled for maintenance and other operations when damaged.

[0022] 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.

[0023] Example 1, reference Figures 1 to 5The back of the backpack is provided with a backrest 2, and the backrest 2 is provided with a backrest 3. The backrest 2 is provided with a backrest 3 ...

[0024] In this embodiment, one end and the other end of the frame 2 are processed with a through opening 6, and the two groups of through openings 6 are both fitted with blocks 7. The two groups of blocks 7 are fixed to the box body 1. The two groups of blocks 7 are rotatably connected to the baffle 8 through the connecting shaft. The two groups of baffles 8 are respectively fitted with the arc grooves of the corresponding through openings 6. The baffle 8 is fitted with the arc groove of the through opening 6. The frame 2 can be installed in the box body 1. One end and the other end of the frame 2 are slidably connected with two groups of slide bars 9, and the slide bars 9 can move the curved rod 5 laterally. Guide, multiple groups of sliding rods 9 are respectively fixed to the two groups of curved rods 5, the double-headed screw 3 is fixed with a handle 10, the handle 10 can drive the double-headed screw 3 to rotate, sponge pads 11 are adhered to one end and the other end of the frame 2, the sponge pads 11 are used to increase the comfort of the frame 2 and the back, the two groups of sponge pads 11 are sewn together with the two groups of shoulder straps 12, the shoulder straps 12 are used to carry the box 1, and the two groups of baffles 8 are fixed with paddles 13, and the paddles 13 are used to drive the baffles 8 to rotate.

[0025] The working principle of this embodiment is as follows: when in use, the handle 10 drives the double-headed screw 3 to rotate, so that the two groups of rod bodies 4 can drive the corresponding curved rods 5 to move outward on both sides respectively, canceling the fit with the box body 1, so that the box body 1 can be opened, and then the items in the box body 1 can be taken out, or the two groups of rod bodies 4 drive the corresponding curved rods 5 to fit with the box body 1, so that the opening of the two parts of the box body 1 can be restricted. At this time, the shoulder strap 12 at the frame body 2 is worn, and the frame body 2 and the double-headed screw 3 will be hidden and placed at the back, which is inconvenient for people at the back to dismantle and open the box body 1, which can prevent theft and ensure safe use. If the frame body 2 and the box body 1 need to be disassembled, the paddle 13 can drive the blocking piece 8 to rotate into the arc groove of the outlet 6. At this time, the blocking piece 8 will remove the movement restriction of the frame body 2, and the frame body 2 is separated from the box body 1 and the block 7, so the disassembly can be completed, and then the maintenance and other operations can be carried out.

[0026] 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.
