Description

Technical Field

[0001] This application relates to the field of mechanical connection structure technology, and in particular to a connection structure with a magnetic disassembly structure. Background Technology

[0002] In the market, commonly used multi-layered structures or components requiring stilts, such as electronic equipment assembly, industrial equipment frames, and furniture shelves, all rely on supporting structures to separate and secure the upper and lower layers. Common stilt designs primarily rely on vertical supports to maintain horizontal stability. Modular equipment and temporary display racks, in particular, require this type of connection solution that allows for quick adjustments and provides stability.

[0003] Typically, a structure is used where a stud is supported by a metal column. The lower end has external threads that screw into the threaded holes of the lower component; the upper end is supported by the metal column itself. Some also include hexagonal nuts or screws for securing from both ends, or a sleeve is fitted over the metal column to enhance stability. This design is well-established in applications requiring heavy equipment and building frames to withstand vibration and impact. It is usually made of metal to ensure strength, and the screw holes are precision-machined and tightened.

[0004] Therefore, this connection method places certain requirements on the machining precision of the screw holes in the lower components. If the inner diameter of the screw hole is too large or too small, it will either cause the stud to loosen easily after being screwed in, or it will be difficult to screw in. Moreover, disassembly is not convenient enough. The components cannot be directly and quickly disassembled manually. Tools are needed to unscrew them, making it difficult to disassemble at any time. This limits its applicability in scenarios where frequent component replacement is required. Furthermore, most existing technical solutions are designed for complex environments with high loads and high dynamics, and have not been specifically optimized for low-frequency, stable applications with small spatial changes, resulting in overly complex structures and high manufacturing costs. Utility Model Content

[0005] To address the problems of existing technologies where the iron pillar supporting the stud is difficult to assemble and disassemble, unsuitable for low-frequency, stable, and spatially variable applications, resulting in overly complex structures and high manufacturing costs.

[0006] This application provides a connection structure with a magnetic disassembly structure, including: a first connecting post, a second connecting post, a magnetic body, and a sleeve; The first connecting post has a first end and a second end, the first end being used for fixed connection to a first external structure; The second connecting post has a third end and a fourth end, the third end being used for fixed connection to the second external structure; The magnetic body is disposed between the second end of the first connecting post and the fourth end of the second connecting post, and is connected to the second end of the first connecting post and the fourth end of the second connecting post by magnetic attraction. The sleeve is fitted over the outside of the first connecting post, the magnetic body, and the second connecting post, and the inner wall of the sleeve mates with the outer periphery of the first connecting post, the magnetic body, and the second connecting post to restrict the lateral movement of the first connecting post, the magnetic body, and the second connecting post.

[0007] In one feasible implementation, the magnetic body is any one of a sphere, a block, or a sheet structure.

[0008] In one feasible implementation, both the first connecting post and the second connecting post have regular hexagonal cross sections.

[0009] In one feasible implementation, the sleeve is a hollow cylindrical structure with openings at both ends, and the inner diameter of the sleeve is fitted to the diameter of the magnetic body, so that the magnetic body can move inside the sleeve.

[0010] In one feasible implementation, a first fastener and a second fastener are also included; The first fastener is disposed at the first end of the first connecting post and is used to fix the first connecting post to the first external structure. The second fastener is disposed at the third end of the second connecting post and is used to fix the second connecting post to the second external structure.

[0011] In one feasible implementation, the first fastener is a hexagonal nut, and the second fastener is a screw; The first end of the first connecting column is provided with an external thread, and is fixed by the hexagonal nut engaging with the threaded hole of the first external structure; The third end of the second connecting post is provided with an internal thread, and is fixed by the screw in conjunction with the screw hole of the second external structure.

[0012] In one feasible implementation, the magnetic body is fixed to the second end of the first connecting post by means of adhesive bonding, snap-fitting, or fitting.

[0013] In one feasible implementation, the sleeve is made of metal or plastic.

[0014] In one feasible implementation, the first connecting post, the magnet, and the second connecting post are coaxially arranged, and the axis of the sleeve coincides with the axis of the first connecting post.

[0015] In one feasible implementation, the first connecting post and the second connecting post are made of ferrous material, and the magnetic body is made of strongly magnetic material.

[0016] This application provides a connection structure with a magnetic disassembly mechanism. Through a composite design of magnetic connection and mechanical constraint, it achieves both rapid assembly / disassembly and stable positioning. Based on the principle of "magnetic force provided in the middle, connection provided by the column, and lateral movement restricted by the outer casing," users can select different shapes of magnetic bodies, sleeves of different materials, and different fixing methods according to specific application needs, achieving personalized configuration of the connection structure. This solution is particularly suitable for industrial scenarios requiring frequent assembly / disassembly, such as equipment maintenance and module replacement. The rapid magnetic connection effectively improves assembly efficiency, while the mechanical constraint structure ensures connection stability, making it particularly suitable for equipment connection needs in vibration environments.

[0020] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a full understanding of the implementation of embodiments of the present invention.

[0021] In the market, multi-layered or elevated components, such as electronic equipment assemblies, industrial equipment frames, and furniture shelves, rely on supporting structures to separate and fix the upper and lower layers. Common elevated designs use vertical supports to maintain horizontal stability, while modular equipment and temporary display racks require quick adjustments and stable connections. A common approach is to use iron pillars supporting stud structures, with the lower end threaded into the lower layer's screw holes, and the upper end supporting the upper components. Some are secured with hexagonal nuts or screws, or sleeves to enhance stability. This design is mature in applications involving heavy equipment and building frames that withstand vibration and impact, using metal materials to ensure strength, and precision-machined and tightened screw holes. However, this connection method requires precise machining of the screw holes in the lower components; improper screw hole inner diameter can lead to studs loosening or difficulty in screwing them in. Disassembly is inconvenient, requiring tools to tighten, making it difficult to disassemble at any time, and limiting its applicability in scenarios with frequent component replacements. Furthermore, existing technical solutions are mostly designed for high-load, high-dynamic, and complex environments, and are not optimized for low-frequency, stable scenarios with minimal spatial changes, resulting in complex structures and high costs.

[0022] To address the aforementioned problems, this embodiment relates to a connection structure with a magnetic detachment mechanism, as described above. Figure 1 As shown, it consists of a first connecting post 1, a second connecting post 2, a magnetic body 4, and a sleeve 3.

[0023] The first end of the first connecting post 1 is fixedly connected to the first external structure (such as the equipment base), and its second end is connected to the magnetic body 4 by magnetic attraction; the third end of the second connecting post 2 is fixedly connected to the second external structure (such as the detachable module), and its fourth end is also connected to the magnetic body 4 by magnetic attraction.

[0024] The sleeve 3, as a sleeve structure, completely wraps around the outside of the first connecting post 1, the magnetic body 4, and the second connecting post 2. Its inner wall fits tightly with the outer periphery of the three to form a lateral movement restriction structure.

[0025] The first connecting column 1 and the second connecting column 2 serve as the main load-bearing components, respectively undertaking the function of fixed connection with the external structure. The magnetic body 4, as the core magnetic attraction element, achieves rapid adsorption and separation of the two connecting columns through the properties of its strong magnetic material. The sleeve 3, through its rigid sleeve structure, maintains the axial degree of freedom of connection while forming a lateral constraint through the tight fit between its inner wall and the outer periphery of the component, preventing radial displacement or vibration loosening of the connection structure during use.

[0026] In practical use, sleeve 3 can be made of metal to achieve high-strength rigid constraint, or it can be made of transparent plastic to meet the requirements of visual assembly.

[0027] In terms of application scenarios, the structure of this embodiment is particularly suitable for the rapid assembly of small mechanical devices, such as the rapid replacement of laboratory instrument modules and the disassembly and assembly of components of teaching demonstration models.

[0028] Taking a laboratory instrument as an example, the first connecting post 1 is fixed to the main frame of the instrument, and the second connecting post 2 connects to the detection module. During assembly, the magnetic body 4 is placed at the second end of the first connecting post 1, and the fourth end of the second connecting post 2 is magnetically attracted to the magnetic body 4 by the guiding action of the sleeve 3. During disassembly, only axial tension needs to be applied to achieve rapid separation, effectively improving the efficiency of equipment assembly and disassembly.

[0029] The connection structure with magnetic disassembly provided in this embodiment allows for the transfer of axial force from the first connecting post 1 to the second connecting post 2 at the other end via the magnetic body 4 when the first connecting post 1 is subjected to axial force. Simultaneously, the geometric properties of the magnetic body 4 allow for slight coaxiality deviations or angular tilts between the central axes of the first and second connecting posts 1 and 2. The magnetic force automatically corrects them to a coaxial position. The outer shell of the sleeve 3 provides dust and foreign object protection, as well as lateral restraint to prevent lateral displacement or misalignment of internal components, thus providing a rigid external profile for the entire connection structure.

[0030] This embodiment utilizes a composite design of magnetic attraction and mechanical constraints, employing the principle of "magnetic force provided in the middle, column responsible for connection, and outer casing restricting lateral movement," to achieve both rapid assembly / disassembly and stable positioning of the connection structure. In practical applications, this structure, through the synergistic effect of its components, ensures both reliable connection and ease of operation, making it particularly suitable for industrial scenarios requiring frequent assembly / disassembly, and demonstrating significant technical practicality and economic value.

[0031] In some embodiments of this application, the magnetic body 4 can take any one of three forms: sphere, block, or sheet, each corresponding to different application scenarios. The spherical structure achieves maximum magnetic adsorption through point contact, the block structure provides a more stable magnetic attraction effect through surface contact, and the sheet structure adapts to space-constrained installation environments through its thin design.

[0032] The spherical magnetic body 4 can be made of neodymium iron boron material to achieve high-strength point contact adsorption, which is suitable for precision instrument positioning scenarios; the block magnetic body 4 can be made of ferrite material, which improves magnetic attraction stability by increasing the contact area, and is suitable for heavy equipment connection scenarios; the sheet magnetic body 4 can be made of flexible magnetic material to adapt to curved surface installation requirements, and is suitable for flexible electronic equipment assembly scenarios.

[0033] This embodiment achieves adaptability expansion of the connection structure to different application scenarios through the diversified design of the magnetic body 4. The selection of three forms of magnetic body 4 not only ensures the basic function of magnetic connection, but also improves the performance of the connection structure through structural optimization.

[0034] In some embodiments of this application, the cross-sections of the first connecting column 1 and the second connecting column 2 are both hexagonal structures, and the anti-rotation function of the connecting structure is achieved through the geometric characteristics of the hexagonal cross-section.

[0035] The first end of the first connecting post 1 is fixedly connected to the external structure through the first fixing member 5, and its second end is magnetically attracted to the magnetic body 4; the third end of the second connecting post 2 is fixedly connected to the external structure through the second fixing member 6, and its fourth end is also connected to the magnetic body 4 through magnetic attraction.

[0036] Understandably, the hexagonal cross-section design effectively prevents accidental rotation of the connection structure during use through the geometric constraints of its six sides. Meanwhile, sleeve 3 continues to act as a lateral constraint structure, further enhancing the anti-rotation performance of the connection structure through the tight fit between its inner wall and the hexagonal cross-section.

[0037] Furthermore, the hexagonal cross-section structure is also suitable for mechanical devices requiring precise angular positioning, such as robot joint connections and precision optical platform assembly. Taking robot joint connections as an example, the hexagonal cross-section design ensures precise control of the joint connection angle through the geometric constraints of its six sides. During assembly, the sleeve 3, through its inner wall's tight fit with the hexagonal cross-section, effectively prevents angular displacement of the joint connection structure during use, ensuring the accuracy of robot movement.

[0038] It is understood that in some embodiments, the cross-sections of the first connecting post 1 and the second connecting post 2 can also be other regular polygons, which can achieve the same geometric constraint effect; in some embodiments, the cross-sections of the first connecting post 1 and the second connecting post 2 can also be of any shape, and this application does not impose specific restrictions.

[0039] In some embodiments of this application, the sleeve 3 adopts a hollow cylindrical structure with openings at both ends, and its inner diameter is precisely fitted with the diameter of the magnetic body 4 to ensure that the magnetic body 4 can move smoothly inside the sleeve 3, while the inner wall constraint prevents the magnetic body 4 from radially shifting.

[0040] The sleeve 3 completely encloses the first connecting post 1, the magnetic body 4, and the second connecting post 2, forming a lateral constraint structure through the tight fit between the inner wall and the outer periphery of the components. The magnetic body 4 achieves axial connection with the two connecting posts through magnetic attraction inside the sleeve 3, while the guiding effect of the sleeve 3 ensures the accuracy of the connection process.

[0041] The sleeve 3 can be manufactured using a precision drawing process to achieve a match between its inner diameter and the diameter of the magnetic body 4. The precise control of the inner diameter enables the guiding function of the connection structure. At the same time, the hollow cylindrical structure of the sleeve 3 is designed to fit the diameter of the magnetic body 4, which not only ensures the smoothness of the magnetic connection, but also improves the accuracy of the connection process through the constraint of the inner wall.

[0042] In some embodiments of this application, reference is made to Figures 2-4 As shown, the connection structure with magnetic detachment also includes a first fixing member 5 and a second fixing member 6. The first fixing member 5 is disposed at the first end of the first connecting post 1 and is fixedly connected to the first external structure; the second fixing member 6 is disposed at the third end of the second connecting post 2 and is fixedly connected to the second external structure.

[0043] In some embodiments of this application, the first fixing member 5 adopts a hexagonal nut structure, and its internal thread is threaded to the external thread of the first end of the first connecting column 1; the second fixing member 6 adopts a screw structure, and its external thread is threaded to the internal thread of the third end of the second connecting column 2.

[0044] The first connecting post 1 has an external thread structure at its first end, which enables a tight connection with the external structure through thread engagement with the first fixing member 5. Specifically, the first fixing member 5 can be a standard part to achieve quick engagement with the external thread of the first connecting post 1.

[0045] The third end of the second connecting post 2 has an internal thread structure, which achieves a tight connection with the external structure through thread engagement with the second fixing member 6. The second fixing member 6 can adopt a self-tapping screw structure to adapt to the connection requirements of external structures made of different materials.

[0046] When connecting with external structural components, the double threaded fit is formed by fixing with hexagonal nuts and screws, which effectively improves the vibration resistance and load-bearing capacity of the connection structure, strengthens the fixed connection of the connection structure, and ensures the reliability of the connection.

[0047] In some embodiments, the first fixing member 5 and the second fixing member 6 may also be fixed to the first connecting post 1 and the second connecting post 2 by other fixing methods, such as welding, bonding, etc. The specific fixing method can be selected according to the specific shape of the first external structure and the second external structure to achieve faster and more effective fixing.

[0048] In some embodiments of this application, the magnetic body 4 is fixedly disposed on the second end of the first connecting post 1 by any one of the three methods of bonding, snapping, or fitting.

[0049] For example, adhesive bonding achieves permanent fixation through high-strength adhesives; snap-fit ​​bonding achieves detachable fixation through elastic snap-fit ​​structures; and interlocking bonding achieves a strong connection through geometric interlocking structures.

[0050] The magnetic body 4 achieves axial connection with the fourth end of the second connecting post 2 through magnetic adsorption, while the sleeve 3 ensures the stability of the connection structure through lateral constraint. All three fixing methods, through their structural characteristics, ensure the firm fixation of the magnetic body 4 to the second end of the first connecting post 1. It is understood that the magnetic body 4 can also be fixed using other methods to achieve a firm position; this application does not impose specific limitations.

[0051] By fixing the magnetic body 4 to the second end of the first connecting post 1, it is no longer necessary to separately insert or remove the magnetic body 4 during assembly and disassembly, which can effectively improve the efficiency of assembly and disassembly. At the same time, with a smaller size, it can avoid the loss of the magnetic body 4 or the situation of it getting stuck in the sleeve 3, thus improving the convenience of use.

[0052] It is understandable that the magnetic body 4 can also fix the fourth end of the second connecting post 2, which can also facilitate assembly and prevent loss. This application does not impose any specific limitations.

[0053] In some embodiments of this application, the sleeve 3 can be made of either metal or plastic, corresponding to different application environment requirements. Metal materials provide high-strength rigidity constraints, such as aluminum alloys and stainless steel; plastic materials provide lightweight and insulation properties, such as polycarbonate and nylon.

[0054] For example, aluminum alloy sleeve 3 has a high strength-to-weight ratio, making it suitable for equipment assembly; polycarbonate sleeve 3 has transparent visibility, making it suitable for teaching demonstrations; nylon sleeve 3 has self-lubricating properties, making it suitable for connecting high-frequency moving parts. In some embodiments, sleeve 3 may also be made of other materials to meet the needs of actual application scenarios, such as corrosion-resistant materials for harsh environments, etc., and this application does not impose specific limitations.

[0055] This embodiment achieves the adaptability of the connection structure to different application environments through the diversified material design of the sleeve 3. For example, the selection of metal and plastic materials not only ensures the physical performance requirements of the connection structure, but also improves the adaptability of the connection structure through the optimization of material characteristics.

[0056] In some embodiments of this application, the first connecting post 1, the magnetic body 4, and the second connecting post 2 are coaxially arranged to ensure the axial alignment accuracy of the connection structure. The axis of the sleeve 3 is completely coincident with the axis of the first connecting post 1, and the coaxial design ensures the smooth movement of the connection structure.

[0057] The coaxial arrangement ensures precise magnetic positioning of the magnetic body 4 between the two connecting posts through geometric alignment, while the sleeve 3 provides lateral constraint to the connection structure through its sleeve structure. The coaxial design effectively improves the motion accuracy and stability of the connection structure by reducing eccentricity errors.

[0058] In some embodiments of this application, the first connecting post 1 and the second connecting post 2 are made of ferrous material, and the magnetic body 4 is made of strong magnetic material (such as neodymium iron boron), so as to achieve efficient magnetic connection function through material properties.

[0059] Specifically, the ferromagnetic connecting post, through its ferromagnetic properties, forms a high-strength magnetic connection with the strongly magnetic body 4; the sleeve 3, through its material selection, adapts to different application environment requirements. The combination of ferromagnetic and strongly magnetic materials not only ensures the strength requirements of the magnetic connection but also improves the performance indicators of the connection structure through material optimization.

[0060] Among them, the iron connecting column can be manufactured by cold rolling process to achieve high strength mechanical properties; the neodymium iron boron magnet 4 can be manufactured by powder metallurgy process to achieve high magnetic energy product characteristics.

[0061] Taking heavy equipment assembly as an example, iron connecting columns ensure connection reliability in heavy-load environments due to their high strength; neodymium iron boron magnets achieve efficient magnetic attraction connections through their high energy product. Different material combinations, through optimized design, can effectively improve the load-bearing capacity and vibration resistance of the connection structure.

[0062] The installation steps for the connection structure with magnetic detachment feature of this application are as follows: 1. Use the first fastener to fasten the first end of the first connecting post to the first external structure, and use the second fastener to fasten the third end of the second connecting post to the second external structure.

[0063] 2. Gently place the magnetic object at the center of the second end of the first connecting post. The magnetic object will automatically be attracted and positioned under the action of magnetic force. Then, use metal glue to reinforce it and form a stable connection.

[0064] 3. Insert the sleeve from the second end of the first connecting post until the outer shell covers the length of the first connecting post.

[0065] 4. Align the fourth end of the second connecting post with the opening at the other end of the sleeve. Under the attraction of the magnetic material, the second connecting post will be automatically introduced into the sleeve and precisely engaged with the magnetic material, thus completing the assembly.

[0066] As described in the above embodiments, the connection structure with magnetic disassembly provided in this application achieves both rapid assembly / disassembly and stable positioning through a composite design of magnetic connection and mechanical constraint. In practical applications, users can select different shapes of magnetic bodies, different materials of sleeves, and different fixing methods according to specific scenario requirements to achieve personalized configuration of the connection structure. This solution is particularly suitable for industrial scenarios requiring frequent assembly / disassembly, such as equipment maintenance and module replacement. The rapid magnetic connection effectively improves assembly efficiency, while the mechanical constraint structure ensures connection stability, making it particularly suitable for equipment connection needs in vibration environments.

[0067] This application utilizes standardized component design and modular configuration, eliminating the need for machining screw holes, ensuring strong compatibility, and adapting to components of different sizes and specifications. The size can be flexibly adjusted according to actual application needs, making it suitable for various installation environments and conditions. This significantly improves the product's applicability and convenience, making it suitable for scenarios requiring frequent component replacement. No special tools are needed, allowing for quick disassembly and improving installation efficiency. It achieves performance improvements in connection structures in terms of rapid assembly and disassembly, stable positioning, and environmental adaptability, demonstrating significant technological advancement and application promotion value. It is particularly suitable for industrial assembly, equipment maintenance, and module replacement scenarios, effectively improving production efficiency and equipment reliability.
