Description

Technical Field

[0001] This utility model relates to the field of test paper layered storage technology, specifically to a test paper layered wrinkle-resistant storage clip. Background Technology

[0002] In existing technologies, traditional exam paper clips typically use a clamping structure to store exam papers. The typical usage is as follows: the user first aligns the exam papers, then opens the clip body and manually operates the built-in clips (such as metal clips, spring clips, etc.) to open them. The edge of the exam paper is inserted into the clamping area, and the clips are released, using the elastic pressure of the clips to secure the exam paper. Finally, the clip is closed to complete the storage.

[0003] However, actual teaching scenarios have revealed the following inherent flaws in this type of traditional test paper holder:

[0004] When holding a small number of exam papers (such as a single sheet or less than 5 sheets), the gap between the clip openings does not match the thickness of the thin exam paper, resulting in insufficient effective contact pressure on the clamping surface. In this case, the static friction between the exam paper and the clip is significantly reduced, making it prone to relative slippage under gravity or external vibration, ultimately causing the exam paper to fall off the clamping point. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a layered anti-wrinkle storage clip for exam papers, solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A layered anti-wrinkle storage clip for test papers includes an outer storage clip and an inner storage clip installed inside the outer storage clip. The inner storage clip has four sets. Each inner storage clip includes a transparent base plate. A transparent top plate is fixedly connected to one end of the top surface of the transparent base plate. A lever clip is rotatably connected to one end of the bottom surface of the transparent base plate via a pin. Connecting rings are symmetrically fixed to one side of the lever clip. A second female buckle is fixedly connected to one end of the transparent top plate. A plastic triangular plate is fixedly connected to the other end of the transparent base plate. A label bag is fixedly connected to the surface of the plastic triangular plate. A second female buckle is fixedly connected to one side of the plastic triangular plate.

[0008] Furthermore, the external storage clip includes a base plate and a top plate. A connecting component is installed on one side of the base plate, and a flip hole is opened at one end of the top plate. One end of the top plate slides on the surface of the connecting component through the flip hole. A first flexible strip and a second flexible strip are fixedly connected to the upper and lower ends of the base plate, respectively. A first female buckle is fixedly connected to one end of the first flexible strip and the second flexible strip, respectively. A first female buckle is fixedly connected to both ends of one side of the top plate.

[0009] Furthermore, the connecting assembly includes a connecting block, one end of the base plate is fixedly connected to the connecting block, the top surface of the connecting block is symmetrically fixedly connected to a first curved rod, and locking components are respectively installed at both ends inside the connecting block.

[0010] Furthermore, the connecting assembly also includes a reset damping rod. A reset damping rod is fixedly connected to one side of the connecting block. A movable rod is fixedly connected to one end of the reset damping rod. A second curved rod is symmetrically fixedly connected to the top surface of the movable rod. The first curved rod and the second curved rod form a U-shaped design when combined. One end of the top plate slides on the surface of the first curved rod and the second curved rod through a flip hole.

[0011] Furthermore, the connecting assembly also includes a plug rod, with plug rods fixedly connected to both ends of one side of the movable rod, and a locking hole provided on one side of the plug rod.

[0012] Furthermore, the locking component includes a socket and a locking cavity. A socket is symmetrically provided on one side of the connecting block. One end of the plug rod is slidably connected to the socket. A locking cavity is symmetrically provided inside the connecting block. The locking cavity communicates with the socket. A locking damping rod is fixedly connected to the inner wall of the locking cavity. An L-shaped locking rod is fixedly connected to one end of the locking damping rod. One end of the L-shaped locking rod is inserted into the locking hole.

[0013] This invention provides a layered, wrinkle-resistant exam paper storage clip. Compared with existing technologies, it has the following advantages:

[0014] 1. Through the cooperation of the first flexible belt, the second flexible belt, the first male buckle, the first female buckle, the top plate and the bottom plate, multiple sets of inner storage clips can be clamped and fixed, and the two sides of the inner storage clips can be limited to prevent the test papers inside the inner storage clips from falling to the ground from the top and bottom sides.

[0015] 2. By cooperating with the locking components, insert rod, and locking hole, the engagement and disengagement of the movable rod and connecting block can be controlled, as well as the engagement and disengagement of the first and second curved rods. When the first and second curved rods are separated, it is convenient for personnel to remove the inner storage clip or add an inner storage clip. When the first and second curved rods are combined, it can only be used to flip the inner storage clip, just like flipping through a book, making it convenient for personnel to find the corresponding inner storage clip.

[0016] 3. By placing the test paper between the transparent base plate and the transparent top plate, and then rotating the clamping rod, the test paper can be quickly clamped between the transparent base plate and the transparent top plate. After clamping, the test paper can be clamped again by the cooperation of the plastic triangular plate, the second female buckle and the second male buckle, which can also prevent the test paper from falling off the side of the inner storage rack.

[0017] 4. Since there are 4 sets of internal storage clips, and each set of storage clips has a label bag fixed to its side, each set of internal storage clips can be classified, which also enables the classification of test papers for different subjects.

[0018] 5. The lever clamp has a triangular design and is made entirely of plastic. Therefore, when clamping, the lever clamp can deform according to the thickness of the paper being clamped, thereby achieving the clamping and fixing of test papers of a certain thickness.

[0033] Example

[0034] To address the technical problems mentioned in the background section, the following layered anti-wrinkle storage clip for exam papers is provided:

[0035] Combination Figures 1-9 As shown, this utility model provides a layered anti-wrinkle storage clip for test papers, including an outer storage clip 100 and an inner storage clip 200 installed inside the outer storage clip 100. The inner storage clip 200 is provided in four sets. The inner storage clip 200 includes a transparent base plate 201. A transparent top plate 202 is fixedly connected to one end of the top surface of the transparent base plate 201. A pull rod clip 203 is rotatably connected to one end of the bottom surface of the transparent base plate 201 through a pin. A connecting ring 204 is symmetrically fixedly connected to one side of the pull rod clip 203. A second female buckle 205 is fixedly connected to one end of the transparent top plate 202. A plastic triangular plate 206 is fixedly connected to the other end of the transparent base plate 201. A label bag 207 is fixedly connected to the surface of the plastic triangular plate 206. A second female buckle 208 is fixedly connected to one side of the plastic triangular plate 206.

[0036] By placing the test paper between the transparent base plate 201 and the transparent top plate 202, and then rotating the clamping rod 203, the test paper can be quickly clamped between the transparent base plate 201 and the transparent top plate 202. After clamping, the test paper can be clamped again by the cooperation of the plastic triangular plate 206, the second female buckle 205 and the second female buckle 208, which can also prevent the test paper from falling off the side of the inner storage rack 200.

[0037] Since the inner storage clips 200 are set in 4 sets, and each set of storage clips 200 has a label bag 207 fixed on its side, each set of inner storage clips 200 can be classified, and the test papers of different subjects can also be classified.

[0038] In this embodiment, the external storage clip 100 includes a base plate 101 and a top plate 102. A connecting component is installed on one side of the base plate 101. A page-turning hole 103 is opened at one end of the top plate 102. One end of the top plate 102 slides on the surface of the connecting component through the page-turning hole 103. A first flexible strip 104 and a second flexible strip 105 are fixedly connected to the upper and lower ends of the base plate 101, respectively. A first female buckle 106 is fixedly connected to one end of the first flexible strip 104 and the second flexible strip 105, respectively. A first female buckle 107 is fixedly connected to one end of one side of the top plate 102.

[0039] The first flexible band 104, the second flexible band 105, the first male buckle 106, the first female buckle 107, the top plate 102 and the bottom plate 101 work together to clamp and fix multiple sets of inner storage clips 200, and also limit the two sides of the inner storage clips to prevent the test papers inside the inner storage clips from falling to the ground from the top and bottom sides.

[0040] In this embodiment, the connecting assembly includes a connecting block 108. One end of the base plate 101 is fixedly connected to the connecting block 108, and a first curved rod 109 is symmetrically fixedly connected to the top surface of the connecting block 108. Locking components are respectively installed at both ends inside the connecting block 108. The connecting assembly also includes a reset damping rod 110. One side of the connecting block 108 is fixedly connected to the reset damping rod 110, and one end of the reset damping rod 110 is fixedly connected to a movable rod 111. The top surface of the movable rod 111 is symmetrically fixedly connected to a second curved rod 112. When the first curved rod 109 and the second curved rod 112 are combined, they form a U-shape. One end of the top plate 102 slides on the surfaces of the first curved rod 109 and the second curved rod 112 through a flap hole 103.

[0041] In this embodiment, the connecting assembly further includes a plug rod 113. The plug rod 113 is fixedly connected to both ends of one side of the movable rod 111. A locking hole 114 is provided on one side of the plug rod 113. The locking component includes a socket 115 and a locking cavity 116. A socket 115 is symmetrically provided on one side of the connecting block 108. One end of the plug rod 113 is slidably connected to the socket 115. A locking cavity 116 is symmetrically provided inside the connecting block 108, communicating with the socket 115. A locking damping rod 117 is fixedly connected to the inner wall of the locking cavity 116. An L-shaped locking rod 118 is fixedly connected to one end of the locking damping rod 117, and one end of the L-shaped locking rod 118 is inserted into the locking hole 114.

[0042] By cooperating with the locking component, the insertion rod 113, and the locking hole 114, the engagement and disengagement of the movable rod 111 and the connecting block 108 can be controlled, as well as the engagement and disengagement of the first curved rod 109 and the second curved rod 112. When the first curved rod 109 and the second curved rod 112 are separated, it is convenient for personnel to remove the inner storage clip or add an inner storage clip inside. When the first curved rod 109 and the second curved rod 112 are combined, they can only be used to flip the inner storage clip 200, just like flipping through a book, making it convenient for personnel to find the corresponding inner storage clip 200.

[0043] Working principle and usage process of this utility model:

[0044] In use:

[0045] The combination of the first female buckle 106 and the first female buckle 107 will form a set of hidden snaps, and the combination of the second female buckle 208 and the second female buckle 205 will also form a set of hidden snaps;

[0046] The connection between the transparent top plate 202 and the transparent bottom plate 201 can be repeatedly bent, and the connection between the transparent bottom plate 201 and the plastic triangular plate 206 can also be repeatedly bent;

[0047] When storing the exam papers, first, pull the transparent base plate 201 and transparent top plate 202. As the transparent base plate 201 and transparent top plate 202 rotate a certain angle along the lever clamp 203, one end of the transparent base plate 201 and transparent top plate 202 will no longer be located within the lever clamp 203, and the lever clamp 203 will no longer clamp the surfaces of the transparent base plate 201 and transparent top plate 202. At this point, the worker can separate the second male buckle 208 and the second female buckle 205. After separation, rotate the plastic triangle plate 206 until it is parallel to the transparent base plate 201. Then, rotate the transparent top plate 202. After the transparent top plate 202 opens, the worker can place the arranged exam papers onto the transparent base plate 201. Then, rotate the transparent top plate 202 again and flip it over to cover the exam papers. After covering, the worker can then proceed with... Rotate the plastic triangle 206 so that it covers the transparent top plate 202, and connect the second male buckle 208 with the second female buckle 205. After connection, the plastic triangle 206 can limit and fix one end of the test paper, preventing it from falling off the side of the inner storage clip 200. After connection, the staff rotates the transparent bottom plate 201 and the transparent top plate 202 back at a certain angle, so that one end of the transparent bottom plate 201 and the transparent top plate 202 is stuck in the lever clip 203, which also achieves clamping and storage of the test paper. After the test paper is clamped and stored, the staff writes the corresponding subject on the label paper, and then puts the label paper into the label bag 207 through the side opening of the label bag 207. This completes the storage and clamping of test papers of the same subject. Since there are 4 sets of inner storage clips, test papers of 4 different subjects can be stored and classified.

[0048] After all the test papers are collected, the staff rotates the top plate 102 above the top inner storage clip 200, and then flips the first flexible strip 104 and the second flexible strip 105. The first flexible strip 104 and the second flexible strip 105 are then fixed together with the bottom plate 101 and the top plate 102 by the first male buckle 106 and the first female buckle 107, respectively. This fixes the four sets of inner storage clips 200 between the bottom plate 101 and the top plate 102, and also prevents the test papers from falling out due to the inner storage clips 200 not being held tightly.

[0049] When it is necessary to remove the inner storage clip 200 from the outer storage clip 100 later;

[0050] First, separate one end of the first flexible band 104 and the second flexible band 105 from the top plate 102. After separation, the operator presses the L-shaped locking rod 118. As the L-shaped locking rod 118 moves, it compresses the locking damping rod 177. Simultaneously, one end of the L-shaped locking rod 118 disengages from the locking hole 114. After disengagement, the reset damping rod 110 begins to compress the movable rod 111. When the movable rod 111 moves, it drives the insertion rod 113 to slide within the insertion hole 115. At the same time, the movable rod 111 drives... The second curved rod 112 is moved away from the second curved rod 109. At this time, the worker flips the top plate 102, then flips the inner storage clip 200 and finds the inner storage clip 200 that needs to be removed. Then, the connecting ring 204 on the inner storage clip 200 that needs to be removed is aligned with the notch in the middle of the first curved rod 109 and the second curved rod 112. Then, the inner storage clip 200 is lifted upwards to remove it. Conversely, a new set of inner storage clips 200 is installed inwards.
