Description

Technical Field

[0001] This utility model relates to the field of archival restoration technology, and in particular to a fixing clip for the restoration of paper archives. Background Technology

[0002] Paper archives are records that use paper as their medium. These include original documents, drawings, letters, telegrams, household registers, account books, contracts, certificates, manuscripts, diaries, notes, and genealogies. Paper archives are easily damaged, cannot be reproduced, and require confidentiality. Therefore, the protection and restoration of these archives are essential tasks in archival work. Archival restoration involves many meticulous steps, such as deacidification treatment, stain removal, text reinforcement, and paper repair.

[0003] Paper archives are widely used, and when they are damaged, clips are used to secure them for later repair. However, existing clips have shortcomings. Most conventional clips can only hold the paper archive from both sides, leaving the entire surface exposed. During restoration work, restorers inevitably touch areas of the paper other than the clipped areas. This puts previously intact writing at constant risk of damage. Utility Model Content

[0028] Reference Figures 1-7 This invention provides a fixing clip for the restoration of paper archives, comprising a placement platform 1 with U-shaped frames on both sides, and a combined protective frame 2 that can slide along the axial direction of the placement platform 1 in each of the two U-shaped frames, with a gap of 1-2 cm between the combined protective frame 2 and the placement platform 1.

[0029] The combined protective frame 2 is composed of several protective blocks 21 arranged closely along the width of the placement platform 1. The length of the protective block 21 is twice the length of the placement platform 1. Adjacent protective blocks 21 are slidably connected by mortise and tenon structures on both sides. Specifically, one side is provided with a dovetail tenon 211 and the other side is provided with a dovetail mortise 212. The mortise and tenon structure formed by the dovetail tenon 211 and the dovetail mortise 212 can connect two adjacent protective blocks 21 together and their positions can be adjusted independently.

[0030] The inner walls on both sides of the convex frame are respectively provided with guide rail grooves 11 and guide rail strips 12. The guide rail grooves 11 are slidably engaged with the dovetail tenon 211 on one side of the corresponding protective block 21, and the guide rail strips 12 are slidably engaged with the dovetail tenon grooves 212 on one side of the corresponding protective block 21. Through the cooperation between the guide rail grooves 11 and guide rail strips 12 on the convex frame and the protective block 21, the protective block 21 can move along the axial direction of the placement platform 1 on the convex frame. At the same time, the convex frame can provide support for the combined protective frame 2.

[0031] The placement platform 1 is provided with several symmetrically distributed pressing frames 3. Each pressing frame 3 includes a pressure plate 31 disposed between the combined protective frame 2 and the inner top wall of the placement platform 1. At least one positioning rod 32 that slides through the placement platform 1 is fixed to the top of the pressure plate 31. A first screw 33 is rotatably connected to the top of the pressure plate 31 and is threaded through the placement platform 1. The pressing frame 3 can press multiple protective blocks 21, thereby fixing the position of the protective blocks 21 and preventing the protective blocks 21 from shifting during the repair of paper archives, thus improving the fixing effect.

[0032] The protective block 21 has an installation groove 4 on its side near the middle of the placement platform 1. A fixing frame 5 for fixing paper documents is installed in the installation groove 4. The fixing frame 5 includes a clamp 51 hinged in the installation groove 4. A rubber pad 52 is fixed to one side of the bottom of the clamp 51. A second screw 53 is threaded to the inner wall of the top of the installation groove 4. The bottom end of the second screw 53 is rotatably connected to a pull frame 54 that is movably sleeved on the clamp 51. The rubber pad 52 and the pull frame 54 are located on both sides of the hinge point of the clamp 51. The fixing frame 5 at the bottom of the protective block 21 can press and fix the outer perimeter of the area to be repaired of the paper documents, so that the fixing point is close to the area to be repaired, improving the fixing effect and effectively preventing the paper from wrinkling.

[0033] like Figure 3 and Figure 4 As shown, multiple sliding grooves 6 are provided on both sides of the placement platform 1. Damping sleeves 7 are fixed in each sliding groove 6. A push rod 8 is fixed at the bottom of the protective block 21. The push rod 8 slides into the corresponding sliding groove 6, and the push rod 8 and the corresponding damping sleeve 7 are interference-fitted. Through the cooperation of the sliding groove 6 and the push rod 8, the protective block 21 can be supported and limited, making its movement smoother. In addition, the damping sleeve 7 can make the push rod 8 have resistance when moving, so that the protective block 21 can be temporarily fixed after the position is adjusted, which facilitates subsequent fixing.

[0034] Working principle: When fixing the paper archives flat on the placement table 1, the restorer pulls the individual protective blocks 21 one by one according to the repair position, adjusting their positions until the protective blocks 21 are at the edge of the repair area. Then, the protective blocks 21 on the other side of the placement table 1 are adjusted so that the repair area is between the two protective blocks 21. After adjusting the positions of all the protective blocks 21, the first screw 33 is turned first to lower the pressure plate 31 to fix the protective blocks 21. Then, according to the size of the paper archives and the area of ​​the repair area, the second screws 53 are turned in appropriate positions one by one to move the pull frame 54 upward and abut against the clamp 51. The clamp 51 rotates with its hinge point as the center, and the rubber pad 52 presses the paper archives to achieve a multi-point fixing effect, which facilitates the fixing of the paper archives. At the same time, only the area to be repaired is exposed to prevent interference with the intact position.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
