Description

Technical Field

[0001] This utility model belongs to the field of article assembly technology, and relates to a modular hook-and-joint assembly article assembly component, which is used for the assembly of large objects in the construction industry and other situations where fixed connection is required. It is particularly suitable for narrow spaces where it is not convenient to directly construct large objects. Background Technology

[0002] Currently, in the fields of mechanical manufacturing and construction, scenarios frequently arise where large objects need to be constructed in confined spaces, requiring the assembly of small, easily transportable modular components into these structures. Modular structural components, due to their flexible combination and ease of mass production, have been widely applied in various scenarios such as bridge construction, wooden furniture assembly, and building construction. However, existing modular structural components still have technical shortcomings in practical applications, particularly regarding ease of disassembly, assembly efficiency, and transport adaptability, making it difficult to meet the actual needs for convenient transportation, efficient reusability, and rapid deployment. To promote the widespread adoption of modular component technology, numerous patented technologies have disclosed targeted optimization solutions.

[0003] Chinese patent number CN201320788612.2, patent name is an emergency steel truss pedestrian bridge. This patent discloses an emergency steel truss pedestrian bridge composed of modular truss pieces, corner braces, end columns and bolt connections. In this patent, the assembly of the components is very time-consuming because there are a large number of pins and bolts and each one needs to be firmly secured.

[0004] Chinese patent number CN202421197282.4, entitled "A Modular Prefabricated Quick-Assembly Wall Structure," provides a modular prefabricated quick-assembly wall structure that connects two wall panel bodies. However, although the connection method is relatively simple during assembly, the spring device is prone to elastic fatigue and is difficult to reset during disassembly, making it difficult for the locking block to exit the slot, thus reducing the utilization rate of the entire component.

[0005] Chinese patent number CN202510357458.0, entitled "A transverse connection structure and construction method for prefabricated steel box girders", discloses a transverse connection structure and construction method for prefabricated steel box girders. Although the transverse connectors in this patent are relatively small in size compared to the steel box girders, their irregular shapes result in low space utilization when stacked on transport vehicles, increasing transportation costs.

[0006] In summary, existing technologies are not well-suited for assembling large objects in confined spaces or under special conditions. Therefore, researching and developing a modular structural component that can balance non-destructive disassembly, efficient assembly, and transport adaptability, while also being compatible with various real-world scenarios, has become a key direction for breaking through existing technological barriers and promoting the large-scale application of modular technology. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and to develop a hook-and-connect assembly component that is easy to disassemble, assemble, and transport, and is applicable to multiple construction application scenarios such as bridges, furniture, and buildings.

[0008] To achieve the above objectives, this utility model relates to a hook-and-joint assembly component for items. Its main functional structure is divided into two functionally compatible assembly models: Type A and Type B. It is manufactured using an integrated processing method of die casting and integral cutting. The Type A assembly component employs a tension arm structure for its tension member. Its main structure includes a main body, tension arm, cylindrical pin, slot, hook, fixing bolt, and pin hole. The main body is uniformly designed as a regular geometric cuboid or isosceles trapezoid. The cuboid main body is used for planar assembly, while the isosceles trapezoid main body uses its hypotenuse to achieve inclined surface assembly. A recessed slot with a through-type groove along the length of one corner of the main body is provided. The cross-sectional dimensions of the slot are the same as those of the tension arm. The cross-sectional dimensions are matched with gaps of 0.1-0.3mm to ensure smooth insertion and the ability to bear vertical loads through surface contact. The tension arm with a double-protruding symmetrical structure on the top surface has two coaxial pin holes at the center of the protrusion, into which vertical cylindrical pins can be inserted in the corresponding slots. A rotating hook is fixed at the other corner of the main body corresponding to the slot, and a fixing bolt is fixed at the other corner of the main body corresponding to the tension arm. The fixing bolt and the hook can be locked together by hooking. A round pin is fixed in the center of the slot. After multiple main body parts are arranged in the same direction and closely connected, they are locked together by the tension arm and the slot, and the hook and the fixing bolt, respectively, to form a stable integrated object or building structure.

[0009] The type B article assembly component of this utility model has the same main component structure as the type A article assembly component. Its tension component is a tension hook structure. The tension arm structure of the type A article assembly component is replaced with a tension hook of arc-shaped plate structure to form the type B article assembly component. The inner arc diameter of the tension hook of arc-shaped plate structure matches the outer diameter of the circular pin. The type B article assembly component has the same purpose and function as the type A article assembly component.

[0010] The pull arms or pull hooks involved in this utility model are core components for component connection, all integrated on the outer side of the main body and integrally formed from the same material as the main body. The pull arms are symmetrically distributed cantilever structures with holes. Each main body has two pull arms with symmetrical structures. The diameter of the pin hole at the end of the pull arm is transitionally fitted with the diameter of the cylindrical pin, with a gap of 0.05-0.1mm. The rigid connection and docking assembly structure between the component parts is achieved through the cylindrical pin. The pull hook is an L-shaped hook structure. The inner side of the head of the pull hook is designed with an arc transition surface. The hollow part is reserved with an arc-shaped space matching the size of the cylindrical pin structure. After the pull hook is embedded in the slot of the adjacent main body, it hooks and connects with the cylindrical pin to form a hooked and docking composite assembly structure, realizing the surface contact splicing between the two component parts.

[0011] The article assembly component involved in this utility model can transmit lateral tensile force through its own structure. The symmetrical layout of the tension arm and the L-shaped design of the tension hook are respectively suitable for straight splicing and corner splicing scenarios.

[0012] The hook involved in this utility model is a sheet-like structure extending from the edge of the main body, with the end set as a barbed hook-shaped clamping structure; the fixing bolt is vertically welded or spirally connected to the corresponding position of the adjacent main body component, the diameter of the fixing bolt is smaller than the width of the hook, after the two are hooked, the gap between the assembled components is ≤0.2mm by tightening the fixing bolt, thus forming a secondary reinforcement of the connection between the assembled components.

[0013] During assembly, the pull arm / or pull hook is first inserted into the slot of the adjacent main body and pushed to the limit position, and the cylindrical pin is inserted to complete the initial positioning; then the hook is hooked and locked with the fixing bolt, and the single-unit connection operation is simple; repeating the above steps can realize the rapid splicing of multiple components, and the overall structural shape can be flexibly changed by adjusting the angle of the adjacent components; the load-bearing surface formed after the components are spliced ​​is not limited to a horizontal straight line shape, and can be flexibly set to any shape such as arc, bow, staircase spiral ascent or spiral descent according to actual needs.

[0014] This utility model relates to a composite assembly primarily using a superimposed assembly method, with connections encompassing both coplanar and non-coplanar joining. It involves assembling several components of the same size, shape, or any other structural type, connected end-to-end by hooks or pins. Utilizing the mechanical interlocking characteristics of the hook structure or the precise positioning and fastening effect of the pin connection, the components are interconnected, enabling the assembly into structural facilities and products with a certain load-bearing capacity, such as modular bridges, modular ships, modular furniture, and modular houses.

[0015] Compared with existing technologies, this utility model features a novel design, simple structure, easy assembly and construction, wide applicability, and environmental friendliness. Firstly, leveraging the mechanical compatibility of hook and pin connections, it enables rapid assembly without complex professional tools, reducing manual operation difficulty and time costs. Secondly, the reversible connection structure design minimizes damage to the component body during disassembly, ensuring repeated disassembly and assembly, increasing component reuse rate and reducing overall project costs. Thirdly, its regular shape allows for independent storage, and its volume after storage is compressed to a reasonable proportion compared to the assembled state, significantly reducing transportation and handling difficulties. Fourthly, component size and materials can be flexibly customized according to site terrain conditions and load requirements, achieving a flexible application mode of "one component for multiple scenarios with adaptability."

[0023] The technical solution of this utility model will be further described clearly and completely below with reference to the accompanying drawings and embodiments.

[0024] Example 1:

[0025] This embodiment relates to an application of the aforementioned modular assembly components in emergency rescue bridge construction. Based on a modular splicing structure with interlocking connections, it is suitable for temporary traffic restoration scenarios after natural disasters, requiring rapid assembly to support emergency vehicles and personnel. The overall structure is as follows: Figure 3 As shown, the main body of the interlocking and assembly-type modular component involved adopts an A-type structure. Its main structure includes a main component 1, a tension arm 2, a cylindrical pin 3, a slot 4, a hook 5, a fixing bolt 6, and a pin hole 8. These components are assembled into a single integrated modular component. The main component 1 is made of high-strength steel alloy and has a rectangular frame structure. A pin hole 8 is pre-drilled on the upper part of the tension arm 2. The tension arm 2, with its protruding structure and pin hole 8, interlocks with the slot 4 in the adjacent modular component. The pin hole 8 and the cylindrical pin 3 cooperate for positioning, ensuring a stable and integrated bridge structure after the multiple modular components are assembled. The cylindrical pin 3 is a metal pin-shaped positioning component. The diameter of the cylindrical pin 3 and the mating gap between the pin hole 8, slot 4, and tension arm 2 on the main component 1 are between 0.1mm and 0.3mm, achieving precise alignment. The hook 5 and the fixing bolt hook 6 are securely connected, providing a stable fixation effect for the two components and enhancing the stability of the connection.

[0026] The main component 1 involved in this embodiment is manufactured using an integrated structure process, and its structural dimensions are matched with different relevant structural dimensions according to different object environments. During the overall assembly, the main component 1 is first horizontally positioned with reference to a horizontal datum plane to ensure that the error between its plane and the horizontal plane is less than 1mm / m. Then, the tension arm 2 of the next assembly component is aligned with the slot 4 of the main component 1 of the previous assembly component and inserted. The rectangular guide structure of the slot 4 is used to achieve precise guidance until the root step surface of the tension arm 2 is in contact with the end of the slot 4 of the main component 1. The cylindrical pin 3 is vertically inserted into the pin hole 8 on the main body 1 and fitted into the corresponding hole of the tension arm 2 to ensure a tight fit. The flatness of the splicing surface of the two combined components is less than 0.3mm, achieving a close surface-to-surface assembly connection between the two combined components. Finally, the hook-shaped buckle of the hook 5 of one combined component is hooked and locked to the screw part of the fixing bolt 6 of the other adjacent combined component. The nut of the fixing bolt 6 is tightened with a wrench to compress the splicing gap of the two combined components to less than 0.2mm, reinforcing the airtight connection between the two adjacent combined components.

[0027] Example 2:

[0028] This embodiment relates to a modular quick-assembly furniture, based on a B-type interlocking and assembly-type modular furniture structure. It is suitable for quick assembly of desktops in home and office settings. The overall structure is as follows: Figure 4As shown, its main structure includes a main body 1, a pull hook 7, a cylindrical pin 3, a slot 4, a hook 5, and a fixing bolt 6. The main body 1 is made of solid wood or multi-layer board material and is cut and processed in one piece, with a rectangular frame structure. The pull hook 7 is set on the side of the main body 1 and has an L-shaped hook structure. Its end can be inserted into the slot 4 of the adjacent component. The middle of the hook body has a through hole that matches the cylindrical pin 3. The cylindrical pin 3 is inserted into the through hole of the pull hook 7 in the slot 4 of the adjacent component to achieve hooking and positioning, ensuring the flatness and structural stability of the tabletop after the multi-component splicing. The cylindrical pin 3 is made of hard wood or metal. The diameter and the gap between the through hole of the pull hook 5 are controlled at 0.1mm-0.3mm. After insertion, it can eliminate the radial shaking of the component splicing, achieve precise alignment, and facilitate manual insertion and removal. The hook 5 is made of metal. After the hook 5 and the fixing bolt 6 are hooked together, the components can be tightly fitted by tightening the bolt, further enhancing the anti-loosening ability of the connection.

[0029] In this embodiment, the main component 1 is manufactured using an integrated process, with different sizes of components customized according to the required furniture size. During the overall assembly, the main component 1 is first positioned horizontally with reference to a horizontal datum plane, ensuring that the error between its plane and the horizontal plane is controlled within 1mm / m. Then, the pull hook 7 of the next item assembly component is aligned with the slot 4 of the main component 1 of the previous item assembly component and inserted. The rectangular guide structure of the slot 4 is used to achieve precise guidance until the root step surface of the pull hook 7 is completely fitted with the end of the slot 4 of the main component 1. Finally, the cylindrical pin 3 is vertically inserted into the main component 1. The inner side of the pull hook 7 is tightly fitted with the corresponding arc-shaped hole reserved in the pull hook 7, while ensuring that the flatness of the splicing surface of the two item assembly components is within 0.3mm, so as to achieve a tight surface-to-surface hook-and-joint splicing connection between the two item assembly components; finally, the hook-shaped buckle of the hook 5 of one item assembly component is hooked and locked with the screw part of the fixing bolt 6 of the other adjacent assembly component, and then the nut of the fixing bolt 6 is tightened by wrench to compress the splicing gap of the two item assembly components to within 0.2mm, thereby strengthening the tight connection between the two adjacent item assembly components.

[0030] The modular components described in this embodiment are easy to transport, have regular shapes, and can be stored independently, reducing transportation costs. They are highly efficient to assemble, with mechanical compatibility through pin connections or hooks, allowing for rapid assembly without complex professional tools, reducing the difficulty and time cost of manual operation. In terms of disassembly, the design is reversible, with minimal damage to the component body during the disassembly process, ensuring that the components can be repeatedly disassembled and reassembled for use, improving the component reuse rate and reducing the overall project cost.
