Description

Technical Field

[0001] This utility model specifically relates to a file clip. Background Technology

[0002] Paper archives and electronic archives differ significantly, each with its own advantages and limitations. The current common practice is to manage both in parallel. In the management of paper archives, it is necessary to collect and organize documents to facilitate long-term preservation and subsequent retrieval and use. Traditional document clips include U-shaped clips, round-headed clips, flat-headed clips, and long-tail clips. For example, the utility model patent technology entitled "A Long-Tail Clip" was authorized and announced by the Chinese Patent Office on June 24, 2009, with the announcement number CN101462434A.

[0003] The aforementioned traditional file holders also have some drawbacks in use:

[0004] 1) Traditional document clips are inverted triangles when viewed from the side. When clipping a small number of documents, the clip opening is small, and only the front end of the clip contacts the documents. The contact area is small, and the documents are easy to fall off.

[0005] 2) Traditional file clips have an opening size that cannot be adjusted. Once the thickness of the file exceeds the maximum opening of the clip, it cannot be used. Utility Model Content

[0006] The purpose of this utility model is to provide an archival document fixing clip, which uses parallel movable and fixed clamping plates to hold and fix documents. The two clamping plates have a large contact area with the documents, which is effective in fixing a small number of documents. Moreover, the height between the movable and fixed clamping plates is adjustable, which can accommodate documents of different thicknesses.

[0007] This utility model is achieved through the following technical solution:

[0008] A file clip is characterized by comprising, from bottom to top, parallel fixed clip plate, movable clip plate, and upper plate. The two ends of the fixed clip plate and the upper plate are connected by guide posts. The two ends of the movable clip plate are fitted onto the guide posts. A compression spring is fitted onto the guide post between the upper plate and the movable clip plate. A column is provided on one side of the middle of the upper surface of the fixed clip plate. The upper end of the column passes through the movable clip plate and the upper plate in sequence. A control rod is hinged to the upper end of the column by a first pin. The lower end of the control rod is hinged to the upper end of a connecting rod by a second pin. The lower end of the connecting rod is hinged to the movable clip plate by a third pin.

[0009] Under normal conditions, the movable clamping plate of this invention is attached to the fixed clamping plate under the action of the compression spring. When it is necessary to fix and clamp the file documents, press the upper end of the control lever with one hand. Under the action of the lever, the movable clamping plate overcomes the spring resistance and moves upward, causing the movable clamping plate and the fixed clamping plate to separate. Place the file documents between the movable clamping plate and the fixed clamping plate with the other hand, release the control lever, and under the action of the compression spring, the movable clamping plate moves downward to firmly clamp and fix the file documents. Since the movable clamping plate and the fixed clamping plate are set in parallel, the lower end surface of the movable clamping plate and the upper end surface of the fixed clamping plate are all in contact with the documents, so even if the number of documents is small, they are not easy to fall off.

[0010] The upward movement of the movable clamping plate in this invention is achieved by pressing the control lever, which utilizes the lever principle, saving effort and being easy to use.

[0011] The moving pressure plate of this utility model is provided with a hole for the column to pass through, and there is a gap between the hole and the column so as not to affect the up and down movement of the moving pressure plate.

[0012] The upper plate of this utility model is provided with holes for the column and control rod to pass through, and there is a gap between the holes and the column and control rod so as not to affect the use of the control rod.

[0013] Furthermore, the guide column of this utility model is a sleeve lifting structure, including an upper guide column and a lower guide column. The lower guide column is a hollow structure with an open upper end. The lower guide column hole is a threaded hole, and the upper guide column is a threaded column. The lower end of the upper guide column is inserted into the lower guide column hole, and the two are threadedly connected. The upper end of the upper guide column passes through the upper plate and extends above the upper plate. The upper guide column is provided with upper and lower clamping rings. The upper plate is located between the upper and lower clamping rings, and the compression spring is located between the lower clamping ring and the moving clamping plate.

[0014] By rotating the two upper guide posts, the height of the guide posts can be adjusted, which in turn adjusts the height between the upper plate and the fixed clamping plate. In other words, when the control lever is pressed, the upward height of the moving clamping plate can be changed, thus changing the distance between the moving clamping plate and the fixed clamping plate. Therefore, this utility model can be adapted to use with archival documents of different thicknesses.

[0015] To avoid affecting the use of the control lever, the maximum height of the upper plate must not exceed the height of the first pin.

[0016] In order not to affect the upward and downward movement of the moving clamp, when the moving clamp reaches its highest position, both ends are still mounted on the lower guide posts.

[0017] The upper plate is located between the upper and lower clamping rings of the upper guide column. When the upper guide column rotates and rises and falls, the upper plate rises and falls accordingly.

[0018] Furthermore, to facilitate the rotation of the two upper guide pillars, an adjustment part is provided at the upper end of the two upper guide pillars. A ring of vertical grooves is provided on the outer side of the adjustment part to increase friction and make it easier to rotate the upper guide pillars by hand.

[0019] The control lever of this invention utilizes the lever principle. According to the lever principle, the longer the lever arm, the less effort is required. Therefore, this invention provides an extension rod at the upper end of the control lever, as follows:

[0020] The upper end of the control lever of this utility model is hinged to the rotating extension rod through a fourth pin. The fourth pin is located near the upper end of the control lever and is perpendicular to the control lever.

[0021] The rotating extension rod rotates around the fourth pin. When not in use, it fits against the upper or lower end face of the control rod. When in use, it rotates outward 180° to extend the length of the control rod.

[0022] Furthermore, the lower end of the movable clamping plate of this utility model has a row of serrations distributed along the length direction protruding outward, and the cross-section of the serrations is an inverted triangle. The upper end of the fixed clamping plate has a row of serration grooves distributed along the length direction recessed inward, and the cross-section of the serration grooves is an inverted triangle. The serrations correspond to the serration grooves below, and the size of the serrations is the same as the size of the serration grooves.

[0023] When a small number of files are held between the moving clamp and the fixed clamp, the moving clamp moves downward to fit against the fixed clamp, and the serrations insert into the corresponding serration grooves. The interlocking of the serrations and serration grooves can help to fix and hold the files in place.

[0024] This utility model has the advantages of reasonable structure, flexible and convenient use, and wide applicability. Using this utility model, archives of different quantities and thicknesses can be firmly clamped. Attached Figure Description
