Description

Technical Field

[0001] This utility model relates to a composite structure of sheet materials and a composite sheet material. Background Technology

[0002] In today's construction, furniture manufacturing, and many industrial production sectors, the assembly and connection of panel materials is an extremely common and critical operation. As industries increasingly demand greater product flexibility, maintainability, and versatility, the optimization of panel assembly structures has become increasingly urgent.

[0003] In traditional sheet metal assembly methods, the use of connecting plates and screws for connection was once widely adopted. Specifically, when two sheets of sheet metal need to be joined to form a larger sheet or one with a specific function, the operator typically selects a suitable connecting plate. This connecting plate is usually a long strip of metal or high-strength plastic with pre-designed screw holes at both ends. The connecting plate is then tightly fitted to the corresponding positions of the two sheets to be joined. Screws are then passed through the screw holes on the connecting plate and screwed into the sheet metal. The interlocking force of the threads secures the connecting plate to the two sheets, thus achieving the purpose of connecting the two sheets.

[0004] This connection method has indeed played a role in some relatively fixed scenarios where frequent disassembly is not required. For example, in the construction of non-load-bearing partition walls inside some early permanent building structures, this connection method can quickly complete the splicing of panels, and its stability can meet basic requirements during the long-term use of the building because there is no need to adjust or replace the partition wall panels.

[0005] However, with the development of the times, more and more application scenarios are placing higher demands on the assembly structure of boards. In fields such as modern modular furniture manufacturing, consumers are increasingly pursuing personalization and versatility, often needing to rearrange and reassemble furniture according to changes in living scenarios. Taking a bookshelf that can freely change its form as an example, if the traditional connecting plate and screw connection method is used, when users want to disassemble a module of the bookshelf and replace it with other functional components, such as replacing a regular bookshelf shelf with a storage shelf with drawers, they will face many difficulties. Because screws may rust and have damaged threads after long-term use, and because the connecting plate is tightly fitted to the board, the surface of the board is easily damaged during disassembly, which is not only time-consuming and laborious, but may even damage the entire bookshelf structure, making it impossible to reassemble and use.

[0006] In conclusion, the traditional method of connecting two panels using connecting plates and screws is inherently difficult to disassemble and can no longer meet the current industry demands for convenient and maintainable panel assembly structures. There is an urgent need for a new panel assembly structure and assembly panels to fill this technological gap. Summary of the Invention

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] For reference as follows Figure 1-5 The present invention will be described as follows:

[0030] Example: A plate assembly structure includes two semi-circular fixing plates 1. One side of the fixing plate 1 is provided with a coaxial circular connecting groove 2, which is provided through the radial inner side of the fixing plate 1. This through-type design provides the basic framework for the installation and movement of the subsequent rotating plate 3, so that the connection mechanism of the entire assembly structure can be realized.

[0031] As a component directly connected to the plate body 12, the fixing plate 1 needs to have sufficient strength and stability. Its material is usually selected as high-strength metal alloy or engineering plastic with good mechanical properties to ensure that there will be no deformation or breakage during long-term use, thereby ensuring the reliability of the connection between the two plates.

[0032] It also includes a semi-circular rotating plate 3, the diameter of which is equal to the outer diameter of the connecting groove 2; in this way, the rotating plate 3 can be perfectly fitted into the space formed by the connecting groove 2 and can rotate smoothly in it.

[0033] The rotation function of the rotating plate 3 is the key to realizing the combination and separation of the plates. In terms of material selection, wear resistance must be considered, because frequent rotation will generate friction, while a certain degree of toughness must also be taken into account to prevent cracking due to uneven force during rotation. Therefore, high-quality steel or high-strength wear-resistant plastic with surface hardening treatment is often selected.

[0034] Two fixed pieces 1 are combined to form a circular structure, and two rotating pieces 3 are rotatably connected in the connecting groove 2.

[0035] It also includes a hexagonal operating hole 4 that runs through the center of both rotating plates 3. To facilitate user operation of the rotating plates 3, a hexagonal operating hole 4 was specially designed to run through the center of both rotating plates 3. The hexagonal shape makes it easier to fit with a standard hex wrench. Users can insert a hex wrench into the operating hole 4 to precisely and effortlessly rotate both rotating plates 3 simultaneously, achieving the combination and separation of the plates, greatly improving operational convenience.

[0036] When faced with the actual need to combine two sheet metal bodies 12, the entire assembly structure operates according to the following steps:

[0037] First, tightly press one side of each of the two sheet metal bodies 12 together to ensure a smooth and seamless connection. This is a prerequisite for the accurate and stable installation of the fixing pieces 1. Next, securely connect the two fixing pieces 1 to the two sheet metal bodies 12 using reliable methods such as welding, riveting, or high-strength bolts. At this point, the two fixing pieces 1 form a complete circular structure, and correspondingly, the two connecting grooves 2 also perfectly align to form a circular groove. In this state, the two rotating pieces 3 are accommodated within the circular space formed by the two connecting grooves 2 and can rotate freely around the axis of the connecting groove 2.

[0038] Specifically, when the rotating pieces 3 are each located within a connecting groove 2, the two sheet bodies 12 are separable. At this time, the two sheets are not locked together and can be easily moved and separated, facilitating transportation, storage, or temporary structural adjustments. When it is necessary to securely connect the two sheet bodies 12, a hexagonal wrench is inserted into the hexagonal operating hole 4, and the rotating pieces 3 are rotated, causing them to span the two connecting grooves 2. In this case, the rotating pieces 3 act as a kind of "lock," preventing relative displacement of the two sheet bodies 12 in the direction perpendicular to the connecting surface and in the circumferential direction. This achieves a tight and stable connection between the two sheet bodies 12, meeting the strength and stability requirements of sheet body assembly in practical applications such as building structure construction and furniture assembly. Compared to traditional connection methods, this sheet body assembly structure is not only easier to disassemble but also ensures sufficient connection reliability in the assembled and fixed state, possessing significant practical value.

[0039] The fixing plate 1 has fixing connection holes 5 at both ends. Screws or bolts are inserted into the fixing connection holes 5 to fix the fixing plate to the plate. This design is the key to achieving a stable connection between the fixing plate 1 and the plate. Screws or bolts, as commonly used fastening elements, can accurately enter the fixing connection holes 5, thereby establishing a tight connection with the plate.

[0040] The rotating plate 3 has a thickened portion 6 corresponding to the central hole area of ​​the fixed plate 1, and the thickened portion 6 is flush with the side of the fixed plate 1. During the frequent rotation of the rotating plate 3, the central hole area is a part where the force is concentrated, especially when the rotating plate 3 plays a connecting and locking role, it bears various complex external forces such as tension and pressure from the separation or joining of the two plates. By adding the thickened portion 6, the mechanical strength of this area can be effectively enhanced, avoiding problems such as deformation and breakage due to long-term stress, and ensuring the reliability and durability of the rotating plate 3. At the same time, the flush setting with the side of the fixed plate 1 makes the entire assembly structure more regular in appearance. In some applications with high requirements for appearance, such as high-end furniture and precision instrument casing assembly, the overall aesthetics will not be affected by the abrupt structure.

[0041] The rotating plate 3 has positioning holes 7 extending through both sides. The positioning holes 7 are threaded holes and can be optionally used. When it is necessary to lock the rotating plate 3 to prevent accidental rotation, bolts can be connected to the positioning holes 7. After the bolts are tightened, they abut against the plate, forming a fixed position. If the frictional force on the rotating plate 3 is sufficient to prevent accidental rotation, the function of the positioning holes 7 can be disregarded.

[0042] Another implementation structure: The outer walls of the two fixing pieces 1, which are combined into a circular structure, are provided with external threads, and a cover 8 is included that can be threadedly connected to the outer walls of the two fixing pieces 1. The primary function of the cover 8 is to hide, cover, and protect the fixing pieces 1. In many practical applications, such as the combination of electronic product casings and high-end decorative panels, the exposure of the fixing pieces 1 may affect the overall aesthetics and refinement. The cover 8 can completely enclose the fixing pieces 1, hiding them from view and presenting a simple and smooth appearance. At the same time, it can also provide physical protection for the fixing pieces 1, preventing them from being damaged by collisions, scratches, corrosion, etc. during daily use and transportation, thus extending the service life of the entire combined panel structure.

[0043] The cover 8 has an operating part 9 at its center, corresponding to the operating hole 4. This design achieves a precise linkage between the cover 8 and the rotating plate 3. When the user needs to rotate the rotating plate 3 to perform the combination or separation of the panels, there is no need to directly contact the rotating plate 3. Simply rotating the cover 8 will indirectly drive the rotating plate 3 to rotate through the operating part 9. This design not only facilitates operation, but also shows its advantages, especially in narrow spaces or scenarios where it is difficult to directly access the rotating plate 3. Moreover, after the cover 8 is rotated into position, the connection between the operating part 9 and the operating hole 4 allows for precise positioning of the rotating plate 3, ensuring that the rotating plate 3 remains in the required state. Whether it is to achieve tight locking or loosening of the panels, it is stable and reliable. In addition, the operating part 9 can be designed with a certain gap from the wall of the operating hole 4. This effectively reduces the frictional resistance between the two when rotating the cover 8, preventing excessive friction from hindering the smooth rotation of the cover 8, and further optimizing the user experience.

[0044] The fixing plate 1 has protruding fixing parts 10 at both ends, and fixing connection holes 5 are provided on the fixing parts 10. This protruding design brings multiple advantages. On the one hand, it increases the contact area between the fixing plate 1 and the plate, making the stress distribution more uniform during connection and reducing the risk of damage to the plate caused by excessive local pressure. This advantage is more significant when connecting brittle material plates. On the other hand, the fixing parts 10 provide more operating space for fastening components, making it easier for operators to tighten screws or bolts. Even in narrow working environments or when using large wrenches or other tools, it is not easily obstructed by surrounding structures, thus improving assembly efficiency.

[0045] The cover 8 is transparent or has a cutout groove 11. The position of the rotating piece 3 can be observed through the cutout groove 11.

[0046] The fixed plate 1 and the rotating plate 3 are made of metal or plastic.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
