[0002] Paper archives are archives that use paper as a carrier, such as original documents and manuscripts of official documents, letters, telegrams, diaries, notes, and family trees that are preserved for reference. Paper archives are easily damaged, cannot be regenerated, and need to be kept confidential. The protection and restoration of archives are tasks that must be taken seriously in archival work.

[0003] The utility model with the existing authorization announcement number CN216688828U discloses a fixing clamp for repairing paper archives, including a placing plate; a fixing groove is opened on the front side of the placing plate, and an elastic member is fixedly connected to the inner wall of the fixing groove, a first rubber pad is fixedly connected to the end of the elastic member away from the fixing groove, and a clamping plate is fixedly connected to the front side of the first rubber pad, and the number of the fixing groove, the first rubber pad and the clamping plate are all four.

[0004] By adopting the above technical solution, paper files can be clamped and fixed quickly and conveniently, and it is easy to take and place and clamp and fix paper files of different thicknesses. However, when the device is in use, due to the relatively fixed structure of the device, the position of the file fixation cannot be adjusted. Therefore, when workers use the device to repair and fix the files, the device can only be used for paper files of a specific size and cannot fix paper files of different sizes, thereby reducing the practicality of the device.

[0005] Therefore, those skilled in the art provide a fixing clip for paper archive repair to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0023] See also Figure 1-4 A fixing clamp for paper archive repair includes a placing table 1, a rubber pad 3 is fixedly installed on the bottom surface of the placing table 1, and the bottom surface of the rubber pad 3 is provided with anti-skid grooves 4 arranged at equal distances. The arrangement of the rubber pad 3 and the anti-skid grooves 4 increases the friction between the placing table 1 and the desktop, so that workers can try to avoid the placing table 1 from moving on its own during the process of repairing paper archives, thereby ensuring the stability of the placing table 1.

[0024] An adjusting mechanism 2 is arranged inside the placing table 1; the adjusting mechanism 2 comprises a connecting shaft 201, which is rotatably connected to the inside of the placing table 1, and a connecting gear 202 and a first conical wheel 203 are fixedly installed on the outer surface of the connecting shaft 201 respectively; two movable plates 204 are slidably connected inside the placing table 1, and a rack plate 205 is fixedly installed on the side where the two movable plates 204 are close to each other, and the side where the two rack plates 205 are close to each other are meshed with the outer surface of the connecting gear 202; a slider 5 is fixedly installed on the bottom surface of each rack plate 205, and two sliding grooves 6 are provided on the inner bottom wall of the placing table 1, and each slider 5 is slidably connected to the inside of the sliding groove 6, and the shape of the slider 5 is T-shaped, and the shape of the sliding groove 6 matches the shape of the slider 5, and the setting of the slider 5 and the sliding groove 6 plays a role in limiting the moving trajectory of the rack plate 205, thereby avoiding the phenomenon that the rack plate 205 deviates from the moving trajectory when moving, thereby ensuring the stability of the movement of the rack plate 205.

[0025] The interior of the placement table 1 is rotatably connected to a rotating shaft 206, and a second conical wheel 207 is fixedly installed on one end of the rotating shaft 206 close to the connecting gear 202. The outer surface of the first conical wheel 203 is meshed with the outer surface of the second conical wheel 207. The outer surface of the rotating shaft 206 is rotatably connected to a bearing seat 7, and the upper surface of the bearing seat 7 is fixedly connected to the inner top wall of the placement table 1. The installation of the bearing seat 7 stabilizes the rotating shaft 206, thereby minimizing the shaking of the rotating shaft 206 during rotation, thereby ensuring the stability of the rotation of the rotating shaft 206.

[0026] A connecting box 208 is fixedly installed on the upper surface of each movable plate 204, and a bidirectional ball screw 209 is rotatably connected inside each connecting box 208. The outer surface of each bidirectional ball screw 209 is threadedly connected to two connecting blocks 210. A sliding rod 8 is fixedly installed on the inner wall of each connecting box 208, and the inner wall of each connecting block 210 is slidably connected to the outer surface of the sliding rod 8. The installation of the sliding rod 8 limits the moving trajectory of the connecting block 210, thereby minimizing the rotation of the connecting block 210 during movement, thereby ensuring the stability of the movement of the connecting block 210.

[0027] A connecting spring 9 is fixedly installed on the inner top wall of each connecting block 210, and a fixing block 10 is fixedly installed on the bottom end of each connecting spring 9. The elastic force of the connecting spring 9 enables the fixing block 10 to cooperate with the placing table 1 to clamp and fix the paper file, thereby minimizing the movement of the paper file when the workers are repairing the paper file, thereby ensuring the stability of the paper file.

[0028] A telescopic rod 11 is fixedly installed on the upper surface of each fixed block 10, and the top end of each telescopic rod 11 is fixedly connected to the inner top wall of the connecting block 210. The installation of the telescopic rod 11 serves to limit the moving trajectory of the fixed block 10, thereby minimizing the phenomenon that the fixed block 10 deviates from the moving trajectory during movement, thereby ensuring the stability of the movement of the fixed block 10.

[0029] The working principle of the utility model is as follows: when in use, the worker first places the placing table 1 on the desktop, and then the worker rotates the rotating shaft 206 according to the size of the paper file to be repaired, so that the rotating shaft 206 drives the second conical wheel 207 to rotate, so that the second conical wheel 207 drives the first conical wheel 203 to rotate, and then the first conical wheel 203 drives the connecting shaft 201 to rotate, and at the same time the connecting shaft 201 drives the connecting gear 202 to rotate, so that the connecting gear 202 drives the two rack plates 205 to move relatively, so that the rack plate 205 drives the moving plate 204 and the connecting box 208 to move relatively, so that the distance between the two connecting boxes 208 matches the width of the paper file. After that, the worker rotates the two bidirectional ball screws 209 respectively, so that the bidirectional ball screws 209 drive the connecting blocks 210 threadedly connected thereto to move, so that the distance between the two connecting blocks 210 on the same bidirectional ball screw 209 matches the length of the paper file, thereby completing the adjustment process of the fixing clamp, and then the worker pulls the fixing block 10 upwards and places the paper file on the placing table 1, and then the worker loosens the fixing block 10, so that the fixing block 10 presses and fixes the four corners of the paper file under the action of the elastic force of the connecting spring 9, thereby completing the fixing process of the paper file, and trying to avoid the paper file from moving on its own during the repair process, thereby ensuring the stability of the paper file.

[0030] What is described above 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.
