Description

Technical Field

[0001] The utility model relates to the technical field of stationery, more specifically to a file drawer clip. Background Art

[0002] File folders are a common office stationery item, primarily used to organize and store documents, papers, and other items. They are widely used in schools, offices, homes, and other places, and are particularly useful for organizing and storing various documents, papers, and other paper products.

[0003] The document drawer consists of a plastic cover and a drawer. To use it, first sort the documents, then pull the drawer out from one end of the cover. Open the cover, align the left sides of all the documents, and place them against the left edge of the cover. Finally, insert the drawer back into the cover from the top or bottom. This drawer eliminates the need for punching and stapling; simply pull and move the drawer to secure and remove documents, making it reusable.

[0004] Currently, the drawer rods of common document drawer clamps are triangular or teardrop-shaped. The paper clamping principle is to clamp the cover and paper through the elastic force generated by the deformation of the rod. When the number of papers clamped is large, the deformation of the drawer rod is greater and the clamping force generated is also greater. At this time, when the drawer rod is installed into the cover, it will generate greater resistance, making it difficult to push the drawer rod in and even damaging the cover. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a document drawer clamp, which can easily hold a large number of papers and avoid damaging the cover.

[0006] The technical solution of the present utility model is to provide a file drawer clamp with the following structure, including a drawer rod, the drawer rod including a clamping rod and a reinforcement rod, the clamping rod is provided with a paper clamping slot, the reinforcement rod is provided with an extrusion slot, a first folding portion is provided on one side wall of the paper clamping slot along the length direction of the clamping rod, and flipping the first folding portion can increase the opening of the paper clamping slot; one end of the reinforcement rod is connected to the outer side of the other side wall of the paper clamping slot.

[0007] After adopting the above structure, the document drawer clamp of the utility model has the following advantages compared with the prior art:

[0008] Since the first folding portion is provided on one side wall of the document drawer clamp of the utility model, when in use, the opening of the paper clamping slot can be enlarged by turning over the first folding portion. Even if a large number of papers are contained in the cover, the left side of the cover can be easily inserted into the paper clamping slot of the clamping rod without damaging the cover, which brings convenience to users.

[0009] As an improvement, a concave portion is provided on one side wall of the paper clamping slot, and the concave portion is the first folding portion. With this structure, the first folding portion has a simple structure and a good folding effect.

[0010] As an improvement, the recess is arranged on the outer side or the inner side of a side wall of the paper clamping slot. With this structure, the structure is simple and easy to manufacture.

[0011] As an improvement, the recess is provided on the outer side of a side wall of the paper clamping slot, and a first protrusion is provided on the inner wall of the extrusion slot of the reinforcement rod to match the recess. When the reinforcement rod is fitted over the clamping rod, the first protrusion engages with the recess. With this structure, the interlocking action of the recess and the first protrusion provides a more secure connection between the reinforcement rod and the clamping rod.

[0012] As an improvement, the recess is provided on the inner side of a side wall of the paper clamping slot, a second protrusion is provided on the outer side of the side wall of the paper clamping slot, and a snap-fit groove is provided on the inner wall of the extrusion groove of the reinforcement rod to match the second protrusion. When the reinforcement rod is fitted over the clamping rod, the second protrusion snaps into the snap-fit groove. With this structure, the second protrusion and the snap-fit groove provide a more secure connection between the reinforcement rod and the clamping rod.

[0013] As an improvement, an undercut is provided on the inner wall of the extrusion groove, and the side wall of the undercut and the inner wall of the extrusion groove form the buckle groove. With this structure, the buckle groove is easier to manufacture.

[0014] As an improvement, the other end of the reinforcement rod is provided with a guide slope. After adopting this structure, when the reinforcement rod is sleeved onto the clamping rod, the guide slope plays a guiding role.

[0015] As an improvement, the thickness of the first folding portion is smaller than the thickness of the side wall of the paper clamping slot. With this structure, the structure is simple and the folding effect is better.

[0016] As an improvement, when the reinforcing rod is mounted outside the clamping rod, the first folding portion is located within the extrusion groove of the reinforcing rod. With this structure, since the first folding portion is located within the extrusion groove of the reinforcing rod when the reinforcing rod is mounted outside the clamping rod, the reinforcing rod can reinforce the strength of the first folding portion. After the reinforcing rod is mounted, the reinforcing rod can limit the first folding portion so that it cannot flip in the direction of increasing the opening of the paper clamping slot, resulting in a more reliable structure.

[0017] As an improvement, the thickness of the one end of the reinforcing rod is less than the thickness of the side wall of the reinforcing rod, and the one end of the reinforcing rod forms a second folding portion. With this structure, the reinforcing rod can be folded more conveniently due to the action of the second folding portion. BRIEF DESCRIPTION OF THE DRAWINGS

Example

[0027] like Figures 1 to 2 As shown, this specific embodiment discloses a document drawer clamp, comprising a drawer rod and a cover, wherein the drawer rod comprises a clamping rod 1 and a reinforcement rod 2.

[0028] The clamping rod 1 is provided with a paper clamping slot 101. When in use, the left side of the cover is inserted into the paper clamping slot 101. The opening of the paper clamping slot 101 gradually increases from the paper outlet to the bottom of the slot, which is convenient for placing and taking out paper. A first folding portion is provided on one side wall of the paper clamping slot 101 along the length direction of the clamping rod 1. When in use, the clamping rod 1 is placed flat on the table. The side wall of the paper clamping slot 101 is usually the side wall on the upper side of the paper clamping slot 101. The thickness of the first folding portion is less than the thickness of the side wall of the paper clamping slot 101. Flipping the first folding portion can increase the opening of the paper clamping slot 101. A recess 102 is provided on one side wall of the paper clamping slot 101. The recess 102 is the first folding portion. The recess 102 is provided on the outer surface of one side wall of the paper clamping slot 101.

[0029] The reinforcing rod 2 is provided with an extrusion groove 201. The height of the inner cavity of the extrusion groove 201 is less than the height of the clamping rod 1. The extrusion groove 201 squeezes the side wall of the paper clamping groove 101 to tighten the paper outlet. One end of the reinforcing rod 2 is connected to the outside of the other side wall of the paper clamping groove 101. The thickness of the one end of the reinforcing rod 2 is less than the thickness of the side wall of the reinforcing rod 2. The one end of the reinforcing rod 2 forms a second folding portion 202. Flipping the second folding portion 202 can easily rotate the reinforcing rod 2. The other end of the reinforcing rod 2 is provided with a guide bevel 203. Under the guidance of the guide bevel 203, the reinforcing rod 2 can be easily inserted into the outside of the clamping rod 1. The inner wall of the extrusion groove 201 of the reinforcement rod 2 is provided with a first protrusion 204 that matches the recess 102; when the reinforcement rod 2 is sleeved on the outside of the clamping rod 1, the first folding portion is located in the extrusion groove 201 of the reinforcement rod 2, and the first protrusion 204 is buckled in the recess 102. The reinforcement rod of the prior art document drawer clamp is directly sleeved on the outside of the clamping rod, and the reinforcement rod and the clamping rod are in a mutually sleeved relationship, and there is no structural connection between the two. The document drawer clamp of the present application is different from the prior art, and the reinforcement rod and the clamping rod cooperate with each other through the first protrusion and the recess, so that the connection between the reinforcement rod and the clamping rod is more reliable and will not come off.

[0030] When using the document drawer disclosed in this embodiment, the left end of a cover is inserted into the paper clamping slot 101. When the cover contains a large number of sheets, the first folded portion is pressed and flipped during insertion into the paper clamping slot 101, thereby increasing the opening of the paper clamping slot 101 and allowing the left end of the cover to be easily inserted. The second folded portion 202 is then flipped, and the reinforcement rod 2 is inserted onto the clamping rod 1. The compression groove 201 of the reinforcement rod 2 compresses the side wall of the paper clamping slot 101, causing the paper clamping slot 101 to clamp the left end of the cover, and the first protrusion 204 is engaged with the recess 102. Example

[0031] like Figure 3As shown, this specific embodiment discloses a document drawer clamp. The difference between the document drawer clamp of this specific embodiment and the document drawer clamp disclosed in Example 1 is that the recess 102' is provided on the inner side of a side wall of the paper clamping slot 101' of the clamping rod 1', and a second protrusion 103 is provided on the outer side of a side wall of the paper clamping slot 101'.

[0032] The inner wall of the extrusion groove 201' of the reinforcement rod 2' is provided with a snap-fit groove 205' that matches the second protrusion 103'. The inner wall of the extrusion groove 201' is provided with an undercut 206. The sidewall of the undercut 206 and the inner wall of the extrusion groove 201' form the snap-fit groove 205. When the reinforcement rod 2' is sleeved onto the clamping rod 1', the second protrusion 103' snaps into the snap-fit groove 205.

[0033] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the principles and spirit of the present application are included in the scope of protection of the present application.
