Description

Technical Field

[0001] This utility model relates to the field of document holder technology, and in particular to a document holder with an improved rotating shaft structure. Background Technology

[0002] In modern society, people need to carry various documents in their daily lives and work, such as ID cards, driver's licenses, vehicle registration certificates, and bank cards. Document holders have become a common tool for convenient storage and protection of these documents. Currently, most document holders have a two-page structure, which greatly limits the number of documents they can hold, typically only two, far from meeting the growing demand for document storage. When attempting to expand the functionality of document holders by adopting a multi-page design, new challenges arise. Since conventional hinge methods cannot be used to connect multiple pages, existing technology often uses adhesive bonding to fix them together. This bonding method makes it difficult for adjacent pages to remain flat when opened. In practical applications, such as when documents need to be photographed for record-keeping, scanned for archiving, or uploaded for online business transactions, uneven pages can cause distorted, blurry, or obstructed photos, failing to clearly and accurately present document information and seriously affecting the effective acquisition and use of document information. This not only causes great inconvenience to users and reduces work and life efficiency, but may also lead to adverse consequences such as poor information transmission and business disruptions in some critical transactions. Therefore, it is necessary to propose an improved technical solution to address these problems. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] An improved swivel structure document holder includes at least two document holder assemblies. Each document holder assembly includes a first clamping plate, a second clamping plate, and a swivel. One end of each of the first and second clamping plates is provided with a sheet metal part. The sheet metal part is bent to form a first bend that wraps around the swivel. The first and second clamping plates are mutually flipped and engaged by the engagement of the first bend with the swivel. The first bends corresponding to the first and second clamping plates are in an axially mutually resisting state on the swivel.

[0005] The rotating shaft of one of the adjacent document clip sets has a reserved portion without the first bend. On one of the sheet metal parts of the other adjacent document clip set, a second bend is bent and set around the reserved portion. The two adjacent document clip sets can flip and cooperate with each other through the cooperation of the reserved portion and the second bend.

[0006] Preferably, the document holders are provided in two groups, with each group containing:

[0007] The sheet metal part of the first clamping plate extends to match the outer protective plate. The outer protective plate is bonded to one side of the first clamping plate, and the other side of the first clamping plate is provided with a first bundle of card pockets.

[0008] The sheet metal part with the second bend is set on the second clamping plate. The second clamping plate has two pieces that are glued to each other. The sheet metal part on the second clamping plate is glued between the two pieces of the second clamping plate. The back-to-back surfaces of the two pieces of the second clamping plate are provided with second bundled card pockets.

[0009] Preferably, the edges of the first clamping plate and the outer protective plate are provided with sealing edges.

[0010] Preferably, both the first and second clamping plates are made of carbon fiber or plastic materials.

[0011] Preferably, in the document clip assembly with the second bend, the sheet metal part of the first clip has a first bend section bent, and the sheet metal part of the second clip has two first bend sections bent. The first bend sections corresponding to the first clip and the second clip are staggered on the pivot to present a state of mutual resistance.

[0012] On the document holder assembly with reserved portions, the sheet metal parts of the first and second clamps are each bent with two first bends, and the first bends of the first and second clamps are spaced apart to form three reserved portions, and the second bends are correspondingly provided with three segments.

[0013] Preferably, on the sheet metal part having the second bend, both the first bend and the second bend have a transition section normal to the sheet metal part.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By using sheet metal parts with a first bend at one end of the first and second clips to cooperate with the pivot, mutual flipping within the group is achieved, and the first bends axially resist each other, ensuring the stability and smoothness of opening and closing of each group of document clips. At the same time, by using the reserved part of the pivot of the adjacent group of document clips to cooperate with the second bend on the sheet metal of another group, mutual flipping cooperation between adjacent groups is achieved. This not only solves the problem that traditional multi-page structures cannot be connected with conventional pivots, but also ensures that adjacent clips remain flat after opening, greatly meeting people's needs for large-capacity document clip storage. It facilitates clear and accurate access to document information in scenarios such as taking photos for storage, scanning for archiving, or uploading document photos for online business processing, significantly improving the practicality and functionality of document clips, effectively avoiding information retrieval problems caused by uneven pages, improving work and life efficiency, and reducing the adverse consequences of information transmission obstruction in critical business processing.

Detailed Implementation

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figure 1-6In this embodiment of the utility model, an improved rotating shaft structure document clip includes at least two sets of document clip groups 1. Each document clip group 1 includes a first clip 10, a second clip 20, and a rotating shaft 30. One end of each of the first clip 10 and the second clip 20 is provided with a sheet metal part 40. The sheet metal part 40 is bent to have a first bent portion 41 that is wrapped around the rotating shaft 30. The first clip 10 and the second clip 20 are mutually flipped and engaged by the cooperation of the first bent portion 41 with the rotating shaft 30. The first bent portions 41 corresponding to the first clip 10 and the second clip 20 are in a state of axial mutual resistance on the rotating shaft 30.

[0028] One of the adjacent document clip assemblies 1 has a reserved portion 42 on the pivot 30 without the first bend 41. On one of the sheet metal parts 40 of the other adjacent document clip assemblies 1, a second bend 43 is also bent and provided, which is wound around the reserved portion 42. The two adjacent document clip assemblies 1 can flip and cooperate with each other through the cooperation of the reserved portion 42 and the second bend 43.

[0029] By providing a sheet metal part 40 with a first bend 41 at one end of the first clamping plate 10 and the second clamping plate 20, which cooperates with the pivot part 30, mutual flipping within the group is achieved. The first bend 41 axially resists each other, ensuring the stability and smoothness of opening and closing of each group of document clips. At the same time, by utilizing the reserved part 42 of the pivot part 30 of the adjacent group of document clips 1 to cooperate with the second bend 43 on the sheet metal part 40 of another group, mutual flipping cooperation between the two adjacent groups is achieved. This not only solves the problem that traditional multi-page structures cannot be connected with conventional pivots, but also ensures that the adjacent two page clamping plates remain flat after opening. This greatly meets people's needs for large-capacity document clip storage, making it convenient to clearly and accurately obtain document information in scenarios such as taking photos for storage, scanning for archiving, or uploading document photos for online business processing. It significantly improves the practicality and functionality of document clips, effectively avoids information retrieval problems caused by uneven pages, improves work and life efficiency, and reduces the adverse consequences of information transmission obstruction in critical business processing.

[0030] Please refer to Figure 3-6 Based on the above technical solution, it is further proposed that the document holder group 1 is provided with two groups, and in each document holder group 1:

[0031] The sheet metal part 40 of the first clamping plate 10 extends to a matching outer protective plate 44. The outer protective plate 44 is bonded to one side of the first clamping plate 10, and a first card pocket 11 is provided on the other side of the first clamping plate 10. This effectively protects the first clamping plate 10, enhances its durability, prevents scratches and wear during daily use, and extends the service life of the document holder. At the same time, the first card pocket 11 on the other side of the first clamping plate 10 provides additional storage space for documents or cards, making it easier to classify and store them, and improving the convenience of storage.

[0032] The sheet metal part 40 with the second bending part 43 is set on the second clamping plate 20. The second clamping plate 20 has two pieces that are glued to each other. The sheet metal part 40 is glued between the two pieces of the second clamping plate 20, which ensures the stability of the structure and makes the second clamping plate 20 less prone to damage during frequent opening and closing. The back-to-back surfaces of the two second clamping plates 20 are provided with second bundled card pockets 21, which further increases the storage capacity of the document holder, meets people's needs for storing multiple documents, and makes it convenient for users to quickly find the required documents.

[0033] Overall, these designs not only address the shortcomings of traditional document holder structures but also significantly improve the practicality, durability, and storage functionality of document holders, providing users with a better user experience.

[0034] Please refer to Figure 4-5 Based on the above technical solution, it is further proposed that the edges of the first clamping plate 10 and the outer protective plate 44 are provided with a sealing edge (not shown in the figure). The sealing edge makes the connection between the first clamping plate 10 and the outer protective plate 44 tighter and more secure, enhances the stability of the overall structure, prevents the outer protective plate 44 from warping or falling off during daily use, and further strengthens the protection of the first clamping plate 10. Moreover, the sealing edge can optimize the appearance of the document holder, making it look more exquisite and beautiful, and improving the user experience.

[0035] Both the first clip 10 and the second clip 20 are made of carbon fiber or plastic. If carbon fiber is used, its high strength and high modulus greatly improve the durability of the clips, making them less susceptible to damage from frequent opening and closing and compression, ensuring long-term stable use. At the same time, the low density of carbon fiber significantly reduces the overall weight of the document clip, making it easier for users to carry and improving usability. If plastic is used, firstly, plastic has good plasticity, making it easy to process into various shapes and complex structures to meet diverse design needs and easily adapt to components such as sheet metal parts 40. Secondly, plastic is relatively inexpensive, reducing manufacturing costs and making the product more competitive in the market. Furthermore, some plastics possess a certain degree of flexibility, which can cushion external impacts to some extent, protecting the document.

[0036] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 6Based on the above technical solution, it is further proposed that on the document clip assembly 1 with the second bending part 43, a first bending part 41 is bent on the sheet metal part 40 of the first clip 10, and two first bending parts 41 are bent on the sheet metal part 40 of the second clip 20. The first bending parts 41 corresponding to the first clip 10 and the second clip 20 are staggered on the pivot 30 to present a state of mutual resistance. This design can ensure that the relative movement between the clips is more stable and precise when each set of document clips is opened and closed, avoiding document wear caused by mutual collision or shaking, while optimizing the overall mechanical structure of the document clip and improving durability.

[0037] On the document holder assembly 1 with reserved portions 42, two first bending portions 41 are bent on the sheet metal parts 40 of the first clamping plate 10 and the second clamping plate 20, and the first bending portions 41 of the first clamping plate 10 and the second clamping plate 20 are spaced apart to form three reserved portions 42. The second bending portions 43 are correspondingly provided with three sections. This greatly enhances the stability and flexibility of the connection between adjacent document holders. The three-section cooperative structure can better distribute the force and prevent damage caused by excessive force at a single point. At the same time, it ensures the smoothness of the adjacent document holders during the flipping process, further solving the flatness problem of traditional multi-page document holders. This makes the entire document holder not only meet the needs of large-capacity storage, but also makes it easier to accurately obtain document information in various scenarios, comprehensively improving the practicality and functionality of the document holder.

[0038] Please refer to Figure 1 and Figure 6 Based on the above technical solution, it is further proposed that on the sheet metal part 40 with the second bending portion 43, both the first bending portion 41 and the second bending portion 43 have a transition section 45 normal to the sheet metal part 40; the transition end can effectively separate the sheet metal part 40, so that the two sets of document clip assemblies 1 will not jam when they are engaged. The transition section 45 can effectively separate the sheet metal part 40, and when the two sets of document clip assemblies 1 are engaged and flipped, it avoids jamming caused by direct contact and friction between the sheet metal parts 40; this not only makes the opening and closing operation of the document clips smoother and greatly improves the user experience, but also reduces wear between parts and extends the service life of the document clips. Meanwhile, the stable and smooth opening and closing process ensures that in various scenarios where it is necessary to open the document holder to obtain document information, such as when taking photos or scanning, the document holder can quickly and smoothly open to the appropriate state, which helps to obtain document information more efficiently and accurately, further optimizing the practicality and functionality of the document holder, and effectively solving the problem of inconvenience in actual use of the traditional multi-page structure of document holders.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
