Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a detachable and assembleable metal structure connector. Background Technology

[0002] With the development of modern construction technology, prefabricated modular houses have been widely used in temporary buildings, emergency housing, and modular construction due to their advantages such as short construction cycle, low environmental pollution, and reusability. Among these, metal walls, as the main enclosure structure of modular houses, are typically assembled from multiple metal panels through splicing. Currently, common splicing methods mainly include welding and mechanical connection using connectors.

[0003] While welding metal plates achieves good structural strength and sealing performance, resulting in a stable and reliable connection, its biggest drawback is the irreversibility of the connection. When the building needs to be demolished or relocated, it is inconvenient to remove the welded metal plates, making detachable assembly impossible. To achieve detachable and reusable walls, existing technologies widely use connectors to assemble metal plates. However, traditional connectors typically require pre-drilling holes at the edges of the metal plates and securing them to the connectors with screws, bolts, or other fasteners. While this method achieves detachable assembly, in practical applications, drilling holes in the metal plates damages the overall structure. Repeated disassembly and reassembly of the metal plates damages their surfaces, reducing structural strength and affecting the reliability of the connection.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a detachable and assembled metal structure connector to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A detachable and assemblable metal structure connector includes a positioning plate, a clamping plate on one side of the positioning plate, a transmission bolt slidably mounted on the surface of the positioning plate, a threaded hole on the surface of the clamping plate, the transmission bolt engaging with the threaded hole, support plates connected to both sides of the surfaces of the positioning plate and the clamping plate, limit rods connected to both sides of the positioning plate, limit holes on the surface of the clamping plate, the limit rods engaging with the limit holes, and a stabilizing clamping mechanism on one side of the limit rods.

[0007] Furthermore, in order to ensure the stability of the clamping connection between the positioning plate and the clamping plate on the two metal plates, the stabilizing clamping mechanism includes a telescopic groove on one side surface of the limiting rod, a return spring connected inside the telescopic groove, a support block connected to the end of the return spring, and a pressure inclined surface on one side of the support block.

[0008] Furthermore, in order to achieve a sealing effect at the connection between the two metal plates, shrinkage grooves are opened on both sides of the surface of the positioning plate and the clamping plate, and sealing rubber strips are installed inside the shrinkage grooves.

[0009] Furthermore, to facilitate the disassembly of the positioning plate and clamping plate, one end of the limiting rod is provided with a transmission thread, and a compression ring is threadedly connected to the surface of the transmission thread. One side of the compression ring is matched with the pressure inclined surface.

[0010] Furthermore, in order to increase the friction when the positioning plate and clamping plate come into contact with the metal plate, anti-slip textures are provided on both sides of the surface of the positioning plate and clamping plate.

[0011] Furthermore, in order to achieve a stable seal at the joints of metal plates of different lengths, both ends of the positioning plate and the clamping plate are provided with threaded grooves, and an extension plate is provided on one side of the threaded groove. The installation and removal bolts are slidably installed on the extension plate and cooperate with the threaded grooves.

[0012] Furthermore, in order to achieve the interconnection between the two metal plates...

[0013] The beneficial effects of this utility model are as follows: Two metal plates that need to be connected are placed between a positioning plate and a clamping plate. By tightening the transmission bolt, the positioning plate and the clamping plate are brought closer together, and the two clamping plates are fixedly clamped. Through the stable clamping mechanism, the distance between the adjusted positioning plate and the clamping plate can be kept stable after the transmission bolt is tightened, thus keeping the two connected metal plates firmly clamped at all times. Even if the transmission bolt is loose, the stability of the connection between the two metal plates can be guaranteed. Furthermore, this connector does not require drilling or welding on the metal plate during installation. While ensuring detachable assembly, it avoids structural damage to the plate body, effectively maintains the strength and appearance integrity of the metal plate, and extends the service life of the metal plate.

[0017] 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.

[0018] According to an embodiment of the present invention, a detachable and assemblable metal structure connector is provided.

[0019] Example 1: like Figures 1-7As shown, a detachable and assemblable metal structure connector according to an embodiment of the present invention includes a metal positioning plate 1, a clamping plate 2 on one side of the positioning plate 1, a transmission bolt 3 slidably mounted on the surface of the positioning plate 1, and a threaded hole 4 on the surface of the clamping plate 2, the transmission bolt 3 cooperating with the threaded hole 4. A pair of support plates 5 are connected to both sides of the surfaces of the positioning plate 1 and the clamping plate 2. By mounting the positioning plate 1 and the clamping plate 2 onto two metal plates 17 that need to be connected, the ends of the metal plates 17 contact the support plates 5, and then by turning the transmission bolt... Bolt 3 causes the transmission bolt 3 to move the positioning plate 1 and the clamping plate 2 closer together, thereby fixing and clamping the two metal plates 17. Limiting rods 6 are connected to both sides of the positioning plate 1, and limiting holes 7 are opened on the surface of the clamping plate 2. The limiting rods 6 cooperate with the limiting holes 7. A stabilizing clamping mechanism 8 is provided on one side of the limiting rods 6. Through the stabilizing clamping mechanism 8, the distance between the adjusted positioning plate 1 and the clamping plate 2 can be kept stable after the end of the limiting rod 6 passes through the limiting hole 7, so that the two metal plates 17 can still be firmly clamped when the transmission bolt 3 is loose.

[0020] like Figures 1-7As shown, the stabilizing clamping mechanism 8 includes a telescopic groove 801 on one side surface of the limiting rod 6. A return spring 802 is connected inside the telescopic groove 801, and a support block 803 is connected to the end of the return spring 802. A pressure-receiving inclined surface 804 is provided on one side of the support block 803. When the end of the limiting rod 6 slides into the limiting hole 7, the support block 803 can be squeezed and retracted into the telescopic groove 801. When the transmission screw drives the positioning plate 1 and the clamping plate 2 to approach each other, the end of the limiting rod 6 can slide through the limiting hole 7. At this time, the elastic force of the return spring 802 can push the support block 803 out of the telescopic groove 801, thereby adjusting the position. After the holiday, the limiting rod 6 is positioned to prevent it from resetting, thus maintaining the adjusted distance between the positioning plate 1 and the clamping plate 2, and firmly clamping the two metal plates 17. The positioning plate 1 and the clamping plate 2 have shrinkage grooves 9 on both sides of their surfaces. Sealing rubber strips 10 are installed inside the shrinkage grooves 9. When the positioning plate 1 and the clamping plate 2 clamp the two metal plates 17, the sealing rubber strips 10 are compressed and shrink into the shrinkage grooves 9, increasing the sealing effect at the connection. One end of the limiting rod 6 has a transmission thread 11, and a compression ring 12 is threaded onto the surface of the transmission thread 11. One side of the compression ring 12 mates with the pressure inclined surface 804. When… When the positioning plate 1 and clamping plate 2 need to be disassembled, the compression ring 12 is turned to move towards the support block 803 and compress the support block 803, causing it to retract into the telescopic groove 801. At this time, the transmission screw is turned to allow one side of the support block 803 to enter the limiting hole 7. The compression ring 12 is then turned in the opposite direction to remove it. The positioning plate 1 and clamping plate 2 can be disassembled by continuously turning the transmission bolt 3. Both sides of the surface of the positioning plate 1 and clamping plate 2 are provided with anti-slip textures 13 to increase the friction when the positioning plate 1 and clamping plate 2 are in contact with the surfaces of the two metal plates 17, thereby increasing the stability of the connection between the metal plates 17. Both ends of the positioning plate 1 and the clamping plate 2 are provided with threaded grooves 14. An extension plate 15 is provided on one side of the threaded groove 14. A mounting bolt 16 is slidably installed on the extension plate 15. The mounting bolt 16 cooperates with the threaded groove 14 to evenly distribute and clamp the connection of the two metal plates 17. When the allowance at one end of the metal plate 17 is insufficient to install another connector, an extension plate 15 of matching length can be selected. The extension plate 15 is fixedly installed at one end of the positioning plate 1 and the clamping plate 2 by means of the mounting bolt 16 on the extension plate 15, thereby sealing the allowance at one end of the metal plate 17 and preventing gaps from appearing at the connection.

[0021] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0022] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the positioning plate 1 and the clamping plate 2 are first placed between two metal plates 17 to be connected, so that the edge end faces of the metal plates 17 contact the pair of support plates 5 on the outer side of the positioning plate 1 and the clamping plate 2 respectively, so as to achieve preliminary positioning. During the installation process, by rotating the transmission bolt 3, it slides on the positioning plate 1 and screws into the threaded hole 4 on the surface of the clamping plate 2. As the transmission bolt 3 is continuously screwed in, its screw part pushes the clamping plate 2 towards the positioning plate 1, thereby driving the clamping plate 2 and the positioning plate 1 to move closer to each other, applying clamping force to the edges of the two metal plates 17 clamped between them, and achieving a firm connection. During this process, the limiting rod 6 is simultaneously inserted into the limiting hole 7 on the clamping plate 2, serving as a guide and preventing deflection. When clamped in place, the end of the limiting rod 6 passes through the limiting hole 7, and the return spring 802 in the internal telescopic groove 801 pushes the support block 803 outward. Since the support block 803 is provided with a pressure-bearing inclined surface 804, it is squeezed and contracted into the telescopic groove 801 by the inner wall of the limiting hole 7 during the insertion of the limiting rod 6. Once the support block 803 has completely passed through the limiting hole 7, the return spring 802 immediately pushes it out, causing the support block 803 to be stuck against the outside of the clamping plate 2, forming a reverse limit, effectively preventing the clamping plate 2 from retracting when the transmission bolt 3 is loose or affected by vibration, thereby ensuring the long-term stability and safety of the connection structure. If there is excess material at the splicing end of the metal plate 17 and a connector cannot be fully installed, an extension plate 15 of matching length can be installed on the threaded groove 14 at the end of the positioning plate 1 and the clamping plate 2, and fixed with the mounting bolts 16 on the extension plate 15. The extension plate 15 then seals the gap at the splicing end, achieving a complete seal and completing the connection between the two metal plates 17.

[0023] 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.
