DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , the present utility model provides a technical solution: a drop-proof stationery box, including:

[0022] lower box body frame 1;

[0023] The adsorption structure is arranged inside the lower box body frame 1;

[0024] The adsorption structure includes a fixed bottom plate 2, two adsorption discs 3, a closing plate 4, two fixed tubes 5 and a stretching plate 6. The outer wall of the fixed bottom plate 2 is fixedly embedded inside the lower box body frame 1. The outer walls of the two adsorption discs 3 are fixedly embedded inside the fixed bottom plate 2. The outer wall of the closing plate 4 is fixedly embedded inside the lower box body frame 1. The outer wall of the stretching plate 6 is slidably embedded inside the lower box body frame 1, the fixed bottom plate 2 and the closing plate 4. The outer walls of the two fixed tubes 5 are respectively fixedly embedded inside the two adsorption discs 3 and are both fixedly embedded inside the fixed bottom plate 2 and the lower box body frame 1. The lower box body frame 1 is provided with three ventilation holes 7 at equal distances at the position of the stretching plate 6.

[0025] In this embodiment: A large number of stationery can be loaded through the lower box body frame 1. The two adsorption discs 3 can adsorb on the desk by using the air pressure difference. Moving the stretching plate 6 can draw air through the three ventilation holes 7, thereby changing the air pressure difference, and acting on the two adsorption discs 3 by means of the two fixed tubes 5. The closing plate 4 can seal the drawing area, which is convenient for changing the air pressure. The air in the adsorption discs 3 can be extracted by using the stretching plate 6, so that the adsorption discs 3 are fixed on the desk, thereby firmly adsorbing the stationery box on the desk, preventing students from knocking the stationery box to the ground, and improving the learning and working efficiency.

[0026] Specifically, a fixed side plate 8 is fixedly arranged on one side of the outer wall of the stretching plate 6, and a pull ring 9 is fixedly arranged on the side of the fixed side plate 8 away from the stretching plate 6.

[0027] In this embodiment: The fixed side plate 8 prevents the stretching plate 6 from extending excessively, and the pull ring 9 is used to pull out the stretching plate 6.

[0028] Specifically, a threaded rod 10 is threadedly embedded on the inner wall of the lower box body frame 1, and a rotating plate 11 is fixedly arranged on the top of the outer wall of the threaded rod 10.

[0029] In this embodiment: By rotating the rotating plate 11, the threaded rod 10 rotates on the lower box body frame 1 and moves downward, thereby pressing against the stretching plate 6 to form a fixation.

[0030] Specifically, an upper box body frame 14 is hinged on the top of the outer wall of the lower box body frame 1, and the closing plate 4 is provided with a notch at the position of the two fixed tubes 5.

[0031] In this embodiment: The upper box body frame 14 and the lower box body frame 1 form a stationery box. By using the notch on the closing plate 4, the air in the three ventilation holes 7 on the lower box body frame 1 and the two fixed tubes 5 can flow.

[0032] Specifically, a sliding sleeve 15 is sleeved on the outer wall of the stretching plate 6, and the outer wall of the sliding sleeve 15 is slidably embedded inside the fixed bottom plate 2.

[0033] In this embodiment: The sliding sleeve 15 enables the stretching plate 6 to slide more tightly and sealably.

[0034] Specifically, four lower rubber sleeves 12 are fixedly sleeved at the outer wall corners of the lower box body frame 1, and four upper rubber sleeves 13 are fixedly sleeved at the outer wall corners of the upper box body frame 14.

[0035] In this embodiment: The four lower rubber sleeves 12 and the four upper rubber sleeves 13 can protect the corners of the stationery box.

[0036] During use, the lower box body frame 1 can hold a large number of stationery items. The two suction cups 3 can be adsorbed on the desk by using the air pressure difference. Moving the stretching plate 6 can draw air through the three ventilation holes 7, thereby changing the air pressure difference, and acting on the two suction cups 3 through the two fixed tubes 5. The closing plate 4 can seal the drawing area, facilitating the change of air pressure. The stretching plate 6 can be used to extract the air in the suction cups 3 to fix the suction cups 3 on the desk, thereby firmly adsorbing the stationery box on the desk, preventing students from knocking the stationery box to the ground, and improving the efficiency of learning and work. The fixed side plate 8 prevents the stretching plate 6 from extending too far, and the pull ring 9 is used. Pull out the stretching plate 6, rotate the rotating plate 11 to make the threaded rod 10 rotate on the lower box body frame 1 and move downward, thereby pressing against the stretching plate 6 to form a fixation. The upper box body frame 14 and the lower box body frame 1 form the stationery box. By using the notch on the closing plate 4, the air in the three ventilation holes 7 on the lower box body frame 1 and the two fixed tubes 5 can flow. The sliding sleeve 15 enables the stretching plate 6 to slide more tightly and sealably, and the four lower rubber sleeves 12 and the four upper rubber sleeves 13 can protect the corners of the stationery box.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
