[0002] Traditional folder opening and closing methods may be relatively simple, such as using metal or plastic clips to secure files. However, with the increasing diversification of office automation and file management needs, the situation is changing.

[0003] Most existing folders have clips to hold paper documents in place by using multiple holes on one edge of the paper to organize and limit the paper documents. However, they cannot limit documents without holes on the edge, and the documents are easy to fall off when picked up, which has certain limitations. Summary of the Invention

[0004] The purpose of this invention is to provide a folder opening and closing device to solve the problems mentioned in the background art.

[0012] Furthermore, the two ends of the sorting telescopic plate are slidably connected to the inner wall of the moving groove, the end of the force-bearing elastic plate away from the push rod is fixedly connected to the surface of the opening and closing plate, the end of the push rod away from the force-bearing elastic plate is rotatably connected to the surface of the opening and closing plate, the end of the extrusion plate away from the concentrating plate is in contact with the surface of the force-bearing plate, the bottom of the concentrating plate is in contact with the bottom of the opening and closing plate, and the bottom of the sorting telescopic plate is in contact with the surface of the opening and closing plate.

[0013] Furthermore, the clamping mechanism includes a T-shaped plate, with driven plates fixedly connected to both ends of the T-shaped plate, a slide rail fixedly connected to the surface of the driven plate, a clamping plate slidably connected to the surface of the slide rail, and a force-bearing spring fixedly connected to the surface of the clamping plate.

[0014] Furthermore, the end of the T-shaped plate away from the driven plate is fixedly connected to the surface of the telescopic plate, the surface of the driven plate is provided with a moving hole, the end of the stabilizing frame away from the pull rod is fixedly connected to the surface of the opening and closing plate, and the end of the pull rod away from the stabilizing frame is rotatably connected to the end of the force-bearing spring.

[0015] Furthermore, the bulletproof mechanism includes a driven bulletproof plate, a pressing elastic plate is fixedly connected to the end of the driven bulletproof plate, a bulletproof telescopic plate is fixedly connected to the surface of the pressing elastic plate, a force-bearing rod is rotatably connected to the end of the driven bulletproof plate, a return spring is fixedly connected to the bottom of the pressing frame, and a slot is fixedly connected to the surface of the opening and closing plate.

[0016] Furthermore, the bottom of the driven bulletproof plate is slidably connected to the inner wall of the groove, the end of the return spring away from the lower pressure frame is fixedly connected to the surface of the opening and closing plate, the end of the force rod away from the driven bulletproof plate is rotatably connected to the end of the lower pressure frame, and the number of driven bulletproof plates is set to four, which are divided into two groups of two each, and the four driven bulletproof plates are symmetrically arranged with the lower pressure frame as the center.

[0017] The present invention has the following beneficial effects:

[0018] This invention employs a sorting mechanism. First, documents are placed on the surface of an opening and closing plate. Then, the operator closes the plate. When the plate closes, a push rod is pushed, compressing a force-bearing elastic plate. This compression causes the elastic plate to bend in the middle, pushing a concentrating plate towards itself. This concentrating plate then retracts the sorting telescopic plate towards itself, simultaneously causing a pressing plate to move towards itself. This pressing plate then compresses the force-bearing plate, pushing it to slide along the inner wall of the moving groove, thus straightening and concentrating the paper documents. When the plate closes, the force-bearing elastic rod moves downwards, pushing a fixing plate downwards. When the fixing plate contacts the documents, it secures them, preventing them from shifting when the document holder is lifted.

[0019] This invention employs a clamping mechanism. When the telescopic plate moves, it drives the T-shaped plate towards the opening / closing plate. The movement of the T-shaped plate then drives the driven plate towards the opening / closing plate, which in turn pushes the clamping plate towards the opening / closing plate. As the clamping plate moves, the pulling force of the lever causes it to slide closer together on the surface of the slide rail. This sliding motion compresses the force spring, which then limits the clamping plate's position. At this point, the opening / closing plate closes, and the clamping plate contacts the surface of the opening / closing plate, thus clamping it and preventing it from resetting, thereby limiting its position.

[0020] This invention employs a bulletproof mechanism. When the clamping plate contacts the opening / closing plate and limits its movement, the clamping plate stops below the bulletproof telescopic plate. The operator presses down on the lower pressure frame towards the opening / closing plate. This pressure pulls the force rod, causing it to move closer together. The force rod's movement pulls the driven bulletproof plate along the inner wall of the groove, causing it to slide closer together and clamping both sides of the clamping plate, thus fixing it in place. As the driven bulletproof plate moves, it pushes the bulletproof telescopic plate to retract closer together. Simultaneously, the sliding of the driven bulletproof plate compresses the lower pressure elastic plate. When the lower pressure elastic plate is compressed, its middle section bends. This bending pushes the bulletproof telescopic plate towards the opening / closing plate, contacting the surface of the clamping plate and fixing it in place. Simultaneously, the movement of the lower pressure frame moves the locking plate towards the opening / closing plate, inserting it into the inner wall of the locking slot for engagement, preventing the locking plate from resetting.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0037] The sorting mechanism 10 includes a sorting telescopic plate 16. When the concentrating plate 11 moves, it pushes the sorting telescopic plate 16 to retract in a direction that brings them closer together. A force-bearing plate 17 is fixedly connected to the surface of the sorting telescopic plate 16. When the pressing plate 15 moves, it presses the force-bearing plate 17.

[0038] The clamping mechanism 30 includes a stabilizing frame 36, and a pull rod 37 is rotatably connected to the end of the stabilizing frame 36. When the clamping plate 34 moves, the pulling force of the pull rod 37 causes the clamping plate 34 to slide in a direction closer to each other on the surface of the slide rail 33.

[0039] The bulletproof mechanism 50 includes a lowering frame 55. The operator will press the lowering frame 55 towards the opening and closing plate 1. A locking plate 56 is fixedly connected to the surface of the lowering frame 55. When the lowering frame 55 moves, it will drive the locking plate 56 to move towards the opening and closing plate 1 and insert it into the inner wall of the locking groove 58 for locking. The locking groove 58 prevents the locking plate 56 from resetting.

[0040] The surface of the hinge plate 1 is provided with grooves, and there are two grooves, which are symmetrically arranged on the surface of the hinge plate 1.

[0041] The sorting mechanism 10 includes a concentrating plate 11. When the force-bearing elastic plate 12 is compressed, its middle part bends. When the middle part of the force-bearing elastic plate 12 bends, it pushes the concentrating plate 11 to move closer to each other. The force-bearing elastic plate 12 is fixedly connected to the surface of the concentrating plate 11. A push rod 13 is rotatably connected to the end of the force-bearing elastic plate 12. A moving groove 14 is opened on the surface of the concentrating plate 11. When the force-bearing plate 17 is compressed, it pushes the sorting telescopic plate 16 to slide closer to each other on the inner wall of the moving groove 14, and straightens and concentrates the paper documents. A pressing plate 15 is fixedly connected to the side of the concentrating plate 11 away from the moving groove 14. When the concentrating plate 11 moves, it drives the pressing plate 15 to move closer to each other. When the opening and closing plate 1 closes, it drives the force-bearing elastic rod 2 to move downward. When the force-bearing elastic rod 2 moves, it pushes the fixing plate 3 to move downward. When the fixing plate 3 contacts the document, it fixes the document and prevents the document inside from shaking when the document rack is picked up.

[0042] The two ends of the tidying telescopic plate 16 are slidably connected to the inner wall of the moving groove 14. The end of the force-bearing elastic plate 12 away from the push rod 13 is fixedly connected to the surface of the opening and closing plate 1. First, the document is placed on the surface of the opening and closing plate 1. Then, the worker closes the opening and closing plate 1. When the opening and closing plate 1 is closed, the push rod 13 will be pushed and squeeze the force-bearing elastic plate 12.

The bottom of the tidying telescopic plate 16 is in contact with the surface of the opening and closing plate 1.

[0043] The clamping mechanism 30 includes a T-shaped plate 31. When the telescopic plate 16 moves, it drives the T-shaped plate 31 to move towards the opening and closing plate 1. Both ends of the T-shaped plate 31 are fixedly connected to driven plates 32. When the T-shaped plate 31 moves, it drives the driven plates 32 to move towards the opening and closing plate 1. A slide rail 33 is fixedly connected to the surface of the driven plate 32. A clamping plate 34 is slidably connected to the surface of the slide rail 33. When the driven plate 32 moves, it pushes the clamping plate 34 to move towards the opening and closing plate 1. A force spring 35 is fixedly connected to the surface of the clamping plate 34. When the clamping plate 34 slides, it squeezes the force spring 35 and limits the clamping plate 34 through the force spring 35. At this time, the opening and closing plate 1 is closed. The clamping plate 34 will contact the surface of the opening and closing plate 1, thereby clamping the opening and closing plate 1 and preventing the opening and closing plate 1 from resetting, thus limiting the opening and closing plate 1.

[0044] The end of the T-shaped plate 31 away from the driven plate 32 is fixedly connected to the surface of the telescopic plate 16. The driven plate 32 has a moving hole on its surface.

A downward elastic plate 52 is fixedly connected to the end of the driven bulletproof plate 51, and a bulletproof telescopic plate 53 is fixedly connected to the surface of the downward elastic plate 52. When the middle part of the downward elastic plate 52 bends, it pushes the bulletproof telescopic plate 53 to move towards the opening and closing plate 1 and interacts with the clamping plate. The surfaces of 34 come into contact, thereby fixing the clamping plate 34. When the driven bulletproof plate 51 moves, it will push the bulletproof telescopic plate 53 to retract in the direction of mutual approach. When the clamping plate 34 comes into contact with the opening and closing plate 1 and limits the opening and closing plate 1, the clamping plate 34 will stop below the bulletproof telescopic plate 53. The end of the driven bulletproof plate 51 is rotatably connected to the force rod 54. The bottom of the lower pressure frame 55 is fixedly connected to the return spring 57. The surface of the opening and closing plate 1 is fixedly connected to the slot 58.

[0046] The bottom of the driven bulletproof plate 51 is slidably connected to the inner wall of the groove. The end of the return spring 57 away from the lower pressure frame 55 is fixedly connected to the surface of the opening and closing plate 1. The end of the force rod 54 away from the driven bulletproof plate 51 is rotatably connected to the end of the lower pressure frame 55. When the lower pressure frame 55 is pressed, it will pull the force rod 54 to move in a direction closer to each other. There are four driven bulletproof plates 51. When the driven bulletproof plate 51 slides, it will squeeze the lower pressure elastic plate 52. When the lower pressure elastic plate 52 is squeezed, the middle part will bend and be divided into two groups of two. The four driven bulletproof plates 51 are symmetrically arranged with the lower pressure frame 55 as the center.

[0047] In use, the document is first placed on the surface of the opening and closing plate 1. Then, the operator closes the opening and closing plate 1. When the opening and closing plate 1 is closed, the push rod 13 is pushed and squeezes the force-bearing elastic plate 12. When the force-bearing elastic plate 12 is squeezed, the middle part will bend. When the middle part of the force-bearing elastic plate 12 bends, it will push the concentrating plate 11 to move towards each other. When the concentrating plate 11 moves, it will push the tidying telescopic plate 16 to retract towards each other. When the concentrating plate 11 moves, it will drive the squeezing plate 15 to move towards each other. When the squeezing plate 15 moves, it will squeeze the force plate 17. When the force plate 17 is squeezed, it will push the tidying telescopic plate 16 towards each other on the inner wall of the moving groove 14. The sliding plate 1 moves in the direction of the paper documents, correcting and concentrating them. When the opening and closing plate 1 is closed, it drives the force-bearing elastic rod 2 to move downward. When the force-bearing elastic rod 2 moves, it pushes the fixing plate 3 to move downward. When the fixing plate 3 contacts the documents, it fixes the documents, preventing them from shaking when the document holder is lifted. When the telescopic plate 16 moves, it drives the T-shaped plate 31 to move towards the opening and closing plate 1. When the T-shaped plate 31 moves, it drives the driven plate 32 to move towards the opening and closing plate 1. When the driven plate 32 moves, it pushes the clamping plate 34 to move towards the opening and closing plate 1. When the clamping plate 34 moves, it slides towards each other on the surface of the slide rail 33 due to the pulling force of the pull rod 37. When the clamping plate 34 slides, it compresses the force spring 35, and the force spring 35 limits the clamping plate 34. At this time, the opening and closing plate 1 is closed, and the clamping plate 34 contacts the surface of the opening and closing plate 1, thereby clamping the opening and closing plate 1 and preventing it from returning to its original position, thus limiting the opening and closing plate 1. When the clamping plate 34 contacts the opening and closing plate 1 and limits the opening and closing plate 1, the clamping plate 34 will stop below the bulletproof telescopic plate 53. The operator will press the lower pressure frame 55 towards the opening and closing plate 1. When the lower pressure frame 55 is pressed, it will pull the force rod 54 to move closer together. When the force rod 54 moves, it will pull the driven bulletproof plate 51 towards the inner wall of the groove. The sliding mechanism clamps the clamping plate 34 on both sides, thus fixing the clamping plate 34. When the driven bulletproof plate 51 moves, it pushes the bulletproof telescopic plate 53 to retract in the direction of mutual approach. When the driven bulletproof plate 51 slides, it squeezes the downward elastic plate 52. When the downward elastic plate 52 is squeezed, the middle part will bend. When the middle part of the downward elastic plate 52 bends, it pushes the bulletproof telescopic plate 53 to move towards the opening and closing plate 1 and contact the surface of the clamping plate 34, thereby fixing the clamping plate 34. When the pressing frame 55 moves, it drives the clamping plate 56 to move towards the opening and closing plate 1 and inserts into the inner wall of the slot 58 for locking. The slot 58 prevents the clamping plate 56 from resetting.
