[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 7 The present invention provides a technical solution: a file folder for a file, comprising a bottom plate 1, two symmetrical side plates 29 are installed on both sides of the bottom plate 1, two symmetrical clamping plates 22 are arranged on the other two sides of the bottom plate 1, a sliding plate 30 is slidably connected between the two side plates 29, a support block 2 is fixedly connected to the upper end of the bottom plate 1, an oblique sliding structure is arranged on the upper end of the support block 2, and a clamping plate 5 slidably connected to the sliding plate 30 is arranged on the upper end of the oblique sliding structure;

[0029] A winding wheel 7 is provided at the lower end of the oblique sliding structure, and a symmetrically positioned mainspring 8 is sleeved on the outer side walls on both sides of the winding wheel 7, and a support seat 9 is fixedly connected to the lower end of the mainspring 8, and the support seat 9 is fixedly connected to the upper end of the bottom plate 1, and a symmetrically positioned reciprocating screw rod 10 is fixedly connected to both ends of the winding wheel 7, and a sliding cylinder 11 is sleeved on the end of the reciprocating screw rod 10 away from the winding wheel 7, and a piston 13 is fixedly connected to the end of the sliding cylinder 11 away from the reciprocating screw rod 10, and an air cylinder 14 is sleeved on the outer side wall of the piston 13, and an air bag structure is provided on the end of the air cylinder 14 away from the piston 13, and the air bag structure can push the clamping plate 22 to clamp in the direction of the sliding plate 30;

[0030] An air jet structure is disposed inside the clamping plate 22 , and the air jet structure is connected to the air bag structure and can jet toward the sliding plate 30 .

[0031] Specifically, refer to Figure 5 When the winding wheel 7 starts to rotate, it will drive the reciprocating screw 10 to rotate synchronously. During the rotation of the reciprocating screw 10, the sliding cylinder 11 is driven to slide back and forth on the outer wall of the reciprocating screw 10. During the sliding of the sliding cylinder 11, the piston 13 is used inside the air cylinder 14 to make the air cylinder 14 inhale and discharge it into the airbag structure.

[0032] Among them, the inclined sliding structure includes an inclined bottom plate 3, the lower end of the inclined bottom plate 3 is fixedly connected to the winding wheel 7, the upper surface of the inclined bottom plate 3 is slidably connected with an inclined sliding plate 4, and the upper end of the inclined sliding plate 4 is in contact with the sliding plate 30, and the sliding plate 30 is provided with a sliding groove 6 running through the upper and lower parts, the sliding groove 6 is slidably connected to the clamping plate 5, and the clamping plate 5 is fixedly connected to the inclined sliding plate 4.

[0033] Among them, one end of the inclined bottom plate 3 close to the winding wheel 7 is rotatably connected to two steering wheels 26, and a connecting rope 25 is wound around the outer wall of the winding wheel 7. The connecting rope 25 passes around the steering wheel 26 and is fixedly connected to the side surface of the inclined slide plate 4.

[0034] Among them, the airbag structure includes a positioning shell 17, which is fixedly connected to the air cylinder 14. An airbag 18 that contacts the sliding plate 30 is provided in the cavity of the positioning shell 17, and the airbag 18 is connected to the air cylinder 14. An L-shaped exhaust pipe 19 is fixedly connected to one end of the positioning shell 17 away from the air cylinder 14, and the L-shaped exhaust pipe 19 is slidably connected to the clamping plate 22.

[0035] The upper end of the L-shaped exhaust pipe 19 is fixedly connected to the connecting shell 20, and the connecting shell 20 is provided with an airbag 21 in the cavity near the clamping plate 22, and the airbag 21 is fixedly connected to the clamping plate 22, and the airbag 21 is connected to the airbag 1 18 through the L-shaped exhaust pipe 19, Figure 6 A spring is sleeved on the outer wall of the L-shaped exhaust pipe 19. When the spring 8 cannot store too much air, the excess gas will be transmitted to the inside of the airbag 21 through the support seat 9, so that the airbag 21 continues to expand and pushes the clamping plate 22 to slide in the direction of the sliding plate 30, thereby clamping the side of the folder at the upper end of the sliding plate 30.

[0036] Specifically, refer to Figure 3 The upper end of the inclined bottom plate 3 is an inclined surface, which is continuously lowered from right to left. At the same time, the lower surface of the inclined slide plate 4 is also an inclined surface and fits the inclined bottom plate 3. When the clamping plate 5 is pushed to slide to the left to expand the distance between it and the right side plate 29, so that more folders can be clamped, the inclined slide plate 4 also slides on the upper surface of the inclined bottom plate 3. During the sliding process, the lower surface of the sliding plate 30 will not be resisted by the inclined slide plate 4, but will be resisted by the sliding plate 30. At the same time, during the sliding process of the inclined slide plate 4, the connecting rope 25 will be continuously pulled, and the connecting rope 25 will drive the winding wheel 7 to rotate, so that the winding wheel 7 rotates and drives the air cylinder 14 to inflate the inside of the air bag 18. However, if there are too many folders on the upper end of the sliding plate 30, This will increase the counterweight of the sliding plate 30, causing the slide groove 6 to begin to press down on the airbag 1 18, thereby reducing the maximum storage capacity of the gas inside the airbag 1 18, allowing more gas to flow into the interior of the airbag 2 21, increasing the pushing force of the airbag 21 on the clamping plate 22, and increasing the clamping force of the clamping plate 22, so that when there are fewer books on the upper end of the inclined sliding plate 4, there will not be a high force to clamp the folders, preventing the folders from being damaged. If the number of folders on the upper end of the sliding plate 30 increases, the clamping force that the side surfaces of the folders can withstand will also increase due to the increase in the number of folders. At this time, the airbag 18 will discharge more gas, causing the clamping plate 22 to clamp the folders firmly to prevent them from tipping over.

[0037] The air injection structure includes an exhaust groove 24 , which is formed on the inner wall of the clamping plate 22 . A plurality of exhaust holes 28 are formed on one side of the clamping plate 22 close to the sliding plate 30 , and the exhaust holes 28 are all connected to the exhaust groove 24 .

[0038] The electric valve 23 is fixedly connected to one side of the exhaust groove 24 close to the second airbag 21 . The electric valve 23 is connected to the second airbag 21 . A resistance switch 27 is arranged on the outer wall of the clamping plate 5 . The resistance switch 27 is electrically connected to the electric valve 23 .

[0039] Specifically, after the file folder is placed on the upper end of the sliding plate 30, the winding wheel 7 is reset by the clockwork 8, and the winding wheel 7 is pulled by the connecting rope 25 to reset the inclined slide plate 4, so that the clamping plate 5 clamps the file folder again. However, when the winding wheel 7 rotates in the opposite direction, the air cylinder 14 will still inflate the air bag 18. Figure 3 When the clamping plate 5 slides to the right to clamp the folder, it will drive the inclined sliding plate 4 to slide, so that the inclined sliding plate 4 pushes the sliding plate 30 to slide upward, thereby reducing the pressure of the sliding plate 30 on the airbag 18, so that the airbag 18 can store the gas delivered by the cylinder 14 to the airbag 18 again. When the resistance switch 27 contacts the folder, the resistance switch 27 is pressed and activated, which will open the electric valve 23 electrically connected to it, thereby releasing the gas inside the airbag 2 21 and the airbag 1 18, and discharging it in the direction of the folder through the exhaust groove 24 and the exhaust hole 28, so as to prevent the folder from being dusty when it is not used for a long time.

[0040] Among them, two positioning grooves 12 are symmetrically opened on the outer wall of the sliding cylinder 11, a positioning frame 15 is fixedly connected to the side surface of the positioning shell 17, and the lower end of the positioning frame 15 is fixedly connected to the bottom plate 1, and two symmetrical positioning rods 16 are fixedly connected to the inner wall of the positioning frame 15, and the positioning rods 16 are slidably connected to the positioning grooves 12 at corresponding positions. The positioning rods 16 are slidably connected to the positioning grooves 12 to limit the sliding cylinder 11. When the reciprocating screw 10 rotates, the sliding cylinder 11 will slide back and forth along the trajectory of the positioning grooves 12.

[0041] Working principle: When in use, first slide the clamping plate 5 away from the connecting rope 25, so that the distance between the clamping plate 5 and the side plate 29 becomes larger to accommodate more folders, and then the folders to be placed can be vertically placed on the top of the sliding plate 30. During the sliding process of the clamping plate 5, the connecting rope 25 will be pulled so that the connecting rope 25 drives the winding wheel 7 to rotate. During the rotation of the winding wheel 7, the reciprocating screw rod 10 drives the piston 13 to slide back and forth inside the air cylinder 14, thereby continuously inflating the inside of the airbag 1 18 and the airbag 2 21, and the airbag 2 2 The expansion of 1 pushes the clamping plate 22 to clamp the folder placed on the upper end of the sliding plate 30, so that the folder will not fall down when it is not clamped by the clamping plate 5. At the same time, if there are too many folders and the center of gravity is too large, it is easy to fall down, the air bag 18 will be pressed down by the sliding plate 30 to increase the clamping force of the clamping plate 22. When the clamping plate 5 is reset to clamp the folder again, it can contact the folder through the resistance switch 27, so that the electric valve 23 opens to discharge the gas inside the air bag 18 and the air bag 21, and the folder is blown away through the exhaust hole 28.

[0042] 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.
