Description

Technical Field

[0001] This utility model relates to the field of stationery and office supplies, and more specifically, to a convenient folder. Background Technology

[0002] Portable folders are lightweight, easy-to-carry file organization tools, typically used to store and manage various documents, files, and data. These folders are designed with convenience, functionality, and ease of use in mind, making them suitable for individuals, students, office workers, or anyone who needs to carry files with them at all times.

[0003] Chinese Patent Announcement No. CN214688692U discloses a convenient folder. This patent features an inner page body with the top edge bent inward to form an upper folded edge and the bottom edge bent inward to form a lower folded edge. Paper is inserted into the upper and lower slots for storage, making document storage convenient and quick. The inner page structure design is simple, reasonable, and quick to process, allowing for mass production. In addition, the edge sealing strip helps to stabilize the inner page structure, making it less likely to fall apart, and it is easy to install and use.

[0004] However, the portable folders mentioned in the above patents only clamp and secure the files before carrying them. In contrast, most existing folders not only need to be clamped, but some are also designed for placement, where files are placed inside the folder and placed on a desk. Therefore, there is an urgent need for a folder that is both easy to carry and can be placed. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a convenient folder that can hold and carry different numbers of files using a main clip and a secondary clip. At the same time, by unfolding multiple assembly plates and using the main clip and secondary clip, the entire folder can be formed into a file rack, thereby making the folder more versatile. This makes the folder not only convenient to hold and carry, but also easy to arrange files, effectively improving the practicality of the folder.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A portable folder includes a base plate and an adapter plate. Multiple assembly plates are hinged between the base plate and the adapter plate, and these assembly plates are fixedly connected by a pair of damping hinges. A main clamping plate is fixedly connected to the upper end of the base plate, and a secondary clamping plate is slidably connected to the upper end of the assembly plates. A winding drum is fixedly connected to the rear end of the main clamping plate and is also fixedly connected to the upper end of the base plate. A winding roller is rotatably connected inside the winding drum, and a roller blind is fixedly connected to the outer end of the winding roller, wrapping around its outer end. The roller blind passes through the winding drum and is fixedly connected to the secondary clamping plates. The main and secondary clamping plates are used to hold and carry different quantities of documents. Furthermore, by unfolding the multiple assembly plates and using them in conjunction with the main and secondary clamping plates, the entire folder can form a file rack, making the folder more versatile. This not only makes the folder easy to hold and carry but also facilitates document arrangement, effectively improving its practicality.

[0010] Furthermore, the upper end of the take-up drum is provided with a rotating hole, and a twisting block is rotatably connected in the rotating hole. The twisting block is fixedly connected to the take-up roller. By rotating the twisting block, the take-up roller can be rotated to roll up the curtain cloth, thereby making the file rack roll up into the form of a folder.

[0011] Furthermore, each of the multiple assembly plates has a positioning groove at its upper end, and the multiple positioning grooves correspond to each other. The roller blind is slidably connected in the positioning groove, and the lower end of the sub-clamp is fixedly connected to a limiting block, which is slidably connected in the positioning groove. The positioning groove and the limiting block are both T-shaped in cross-section. By the roller blind sliding and unfolding along the positioning groove, it can not only prevent the assembly plates from bending accidentally, but also limit the sub-clamp to prevent it from falling off and tipping over.

[0012] Furthermore, a fixing buckle is installed at the front end of the adapter plate, and a first groove is formed at the end of the adapter plate near the fixing buckle. A second pull block is slidably connected in the first groove, and the second pull block is fixedly connected to the fixing buckle. A second limiting block is fixedly connected at the end of the second pull block away from the fixing buckle. A second spring is fixedly connected between the second limiting block and the inner wall of the first groove, and the second spring is wrapped around the outer end of the second pull block. By pulling the fixing buckle, the second pull block pulls the second limiting block to squeeze the second spring, thereby pulling out the fixing buckle to clamp and fix the combined main clamping plate and the secondary clamping plate. Then, under the rebound force of the second spring, the fixing buckle is reset, thereby facilitating the combination of the main clamping plate and the secondary clamping plate to clamp and carry documents.

[0013] Furthermore, the fixing buckle includes an auxiliary clamping plate, which is fixedly connected to the end of the second pull block away from the second limiting block. A second groove is provided on the side end of the auxiliary clamping plate, and a first pull block is slidably connected in the second groove. A first limiting block is fixedly connected to the end of the first pull block near the inner wall of the second groove, and a buckle plate is fixedly connected to the end of the first pull block away from the first limiting block. A first spring is fixedly connected between the first limiting block and the inner wall of the second groove, and the first spring is wound around the outer end of the first pull block. By pulling the buckle plate, the first pull block is subjected to force, which drives the first limiting block to compress the first spring. Then, the buckle plate is used to fasten the main clamping plate, thereby facilitating the clamping of documents between the main clamping plate and the auxiliary clamping plate.

[0014] Furthermore, both the main clamping plate and the secondary clamping plate have a carrying hole in the middle. The carrying hole not only allows the formed file rack to be carried, but also allows the file name to be viewed.

[0032] Example 1:

[0033] Please see Figure 1-4A portable folder includes a base plate 1 and an adapter plate 2. Multiple assembly plates 3 are hinged between the base plate 1 and the adapter plate 2. The multiple assembly plates 3 are fixedly connected to each other by a pair of damping hinges 4. A main clamping plate 5 is fixedly connected to the upper end of the base plate 1. A secondary clamping plate 6 is slidably connected to the upper end of the multiple assembly plates 3. A winding drum 7 is fixedly connected to the rear end of the main clamping plate 5 and is fixedly connected to the upper end of the base plate 1. A winding roller 8 is rotatably connected inside the winding drum 7. A roller curtain 9 is fixedly connected to the outer end of the winding roller 8 and is wound around the outer end of the winding roller 8. The roller curtain 9 passes through the winding drum 7 and is fixedly connected to the secondary clamping plate 6. The main clamping plate 5 and the secondary clamping plate 6 are used to clamp and carry different numbers of documents. At the same time, when the multiple assembly plates 3 are unfolded, they can be used in conjunction with the main clamping plate 5 and the secondary clamping plate 6 to form a file rack, thereby making the folder more versatile. This makes the folder not only convenient to clamp and carry, but also convenient to arrange documents, effectively improving the practicality of the folder.

[0034] The upper end of the take-up drum 7 has a rotating hole, and a rotating block 10 is rotatably connected inside the rotating hole. The rotating block 10 is fixedly connected to the take-up roller 8. By rotating the rotating block 10, the take-up roller 8 can be rotated to roll up the curtain cloth 9, so that the file rack can be rolled up into the form of a folder.

[0035] Multiple assembly plates 3 are provided with positioning grooves 11 at their upper ends, and the multiple positioning grooves 11 correspond to each other. The roller blind 9 is slidably connected in the positioning groove 11. The lower end of the sub-clamp plate 6 is fixedly connected to a limiting block, and the limiting block is slidably connected in the positioning groove 11. The positioning groove 11 and the limiting block are both T-shaped. By sliding the roller blind 9 along the positioning groove 11, it can not only prevent the assembly plates 3 from being bent accidentally, but also limit the sub-clamp plate 6 to prevent it from falling off and tipping over.

[0036] A fixing buckle 12 is installed at the front end of the adapter plate 2. A first groove is opened at the end of the adapter plate 2 near the fixing buckle 12. A second pull block 13 is slidably connected in the first groove and is fixedly connected to the fixing buckle 12. A second limiting block 14 is fixedly connected at the end of the second pull block 13 away from the fixing buckle 12. A second spring 15 is fixedly connected between the second limiting block 14 and the inner wall of the first groove. The second spring 15 is wrapped around the outer end of the second pull block 13. By pulling the fixing buckle 12, the second pull block 13 pulls the second limiting block 14 to squeeze the second spring 15, thereby pulling out the fixing buckle 12 to clamp and fix the main clamping plate 5 and the secondary clamping plate 6. Then, under the rebound force of the second spring 15, the fixing buckle 12 is reset, so that the main clamping plate 5 and the secondary clamping plate 6 can be combined to clamp and carry documents.

[0037] The fixing buckle 12 includes an auxiliary clamping plate 121, which is fixedly connected to the end of the second pull block 13 away from the second limiting block 14.

By pulling the buckle plate 124, the first pull block 122 is subjected to force, which drives the first limiting block 123 to compress the first spring 125. Then, the buckle plate 124 is used to fasten the main clamping plate 5, so as to facilitate the clamping of documents between the main clamping plate 5 and the auxiliary clamping plate 6.

[0038] Both the main clamping plate 5 and the secondary clamping plate 6 have a carrying hole 16 in the middle. The carrying hole 16 not only allows the formed file rack to be carried, but also allows the file name to be viewed.

[0039] When using it, please refer to Figure 1-4 Slide the secondary clip 6 along the upper end of the multiple assembled panels 3 and pull the roller blind 9 to unfold it, forming a file holder. Then place the files between the main clip 5 and the secondary clip 6. If there are few files or if they need to be arranged separately, move the secondary clip 6 to the middle of the multiple assembled panels 3, and rotate and fold the remaining multiple assembled panels 3 together as shown. Figure 4 As shown, different documents can be placed between the main clamping plate 5 and the secondary clamping plate 6, and between the secondary clamping plate 6 and the folded assembly plates 3. When documents need to be carried, the documents are placed between the main clamping plate 5 and the secondary clamping plate 6, and the secondary clamping plate 6 is slid to press them together. The rotating block 10 is then rotated to cause the winding roller 8 to roll up the curtain fabric 9. Then, the excess assembly plates 3 at the bottom of the secondary clamping plate 6 are folded up and placed against the end of the secondary clamping plate 6 away from the main clamping plate 5, with the damping hinge 4 as the turning point. The fastening plate 12 is then pulled to fasten the fastening plate 124 to the end of the main clamping plate 5 away from the main clamping plate 5. The main clamp 5 and the secondary clamp 6 are clamped together at one end away from the secondary clamp 6 to carry the folder. Compared with traditional portable folders, this utility model can achieve the purpose of holding and carrying different numbers of files by clamping the main clamp 5 and the secondary clamp 6. At the same time, by unfolding multiple assembly plates 3 and cooperating with the main clamp 5 and the secondary clamp 6, the entire folder can form a file rack, thereby making the folder more versatile. This makes the folder not only easy to hold and carry, but also easy to arrange files, effectively improving the practicality of the folder.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
