Abstract
Description
Technical Field
[0001] This invention relates to the field of quick assembly and disassembly, and in particular to a quick assembly and disassembly structure. Background Technology
[0002] In existing mechanical connection technologies, traditional disassembly and assembly structures generally suffer from a lack of or ambiguity in limiting mechanisms. Traditional designs typically rely on operator experience or repeated trial assembly to determine whether components are properly installed, such as indirectly confirming the connection status through thread engagement length or the feel of snap-fit closure. This uncertainty directly leads to low disassembly and assembly efficiency, especially in scenarios requiring frequent disassembly and assembly. Operators may repeatedly adjust components due to an inability to accurately determine if they have reached the intended position, or even damage threads or cause snap-fit failure due to over-tightening. More importantly, the lack of a clear mechanical limiting structure exposes components to the risk of loosening under vibration or impact, directly affecting the safety of equipment operation.
[0003] To address the aforementioned shortcomings, this utility model provides a quick assembly / disassembly structure. This structure, through the introduction of a mechanical interlocking design between a limiting protrusion and a limiting groove, achieves feedback and precise positioning during the assembly / disassembly process, solving the problem of determining "whether it is in place" in traditional structures, and significantly improving assembly / disassembly efficiency and connection reliability. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, this utility model provides a quick disassembly and assembly structure. This structure, by introducing a mechanical interlocking design of limiting protrusions and limiting grooves, realizes feedback and precise positioning during the disassembly and assembly process, solves the problem of judging "whether it is in place" in traditional structures, and significantly improves disassembly and assembly efficiency and connection reliability.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] This utility model provides a quick-assembly and disassembly structure, including a rotating shaft seat and a mounting slide rail. The rotating shaft seat is slidably fitted on the mounting slide rail. The rotating shaft seat includes at least one screw and at least one rotation limiting block. The rotating shaft seat is provided with at least one mounting hole. The screw passes through the mounting hole and is fixedly connected to the rotation limiting block. The rotation limiting block is limitedly fitted with the inner cavity of the mounting slide rail. The rotating shaft seat is characterized in that a limiting part is provided on the side of the rotation limiting block near the rotating shaft seat, and a mating part is provided on the rotating shaft seat that slidably fits with the limiting part.
[0007] As described above, in a quick-assembly and disassembly structure, the pivot seat is provided with a stop threaded hole for installing a stop screw, and the pivot seat is stopped by the stop screw on the mounting slide rail.
[0008] In the quick assembly / disassembly structure described above, the limiting part is a limiting protrusion, and the mating part is a limiting groove.
[0009] In the quick assembly / disassembly structure described above, the limiting part is a limiting groove, and the mating part is a limiting protrusion.
[0010] In the quick assembly / disassembly structure described above, the inner cavity cross-section of the mounting slide rail is a trapezoidal design.
[0011] In the quick-assembly structure described above, the screw is an internal hexagon screw.
[0012] In the quick assembly / disassembly structure described above, one side of the rotating limiting block is provided with a rounded corner.
[0013] In the quick-assembly structure described above, the rotating limiting block is fixedly fitted to the end of the screw by strong adhesive.

[0015] In the quick assembly / disassembly structure described above, the rotation path on the limiting groove is 0° to 180°.
[0016] The beneficial effects of this utility model are as follows: the rotating shaft seat serves as a rotational support and sliding body. The rotating shaft seat and the mounting slide rail form a sliding connection, allowing the rotating shaft seat to move axially along the mounting slide rail to achieve position adjustment. The rotating shaft seat provides mounting for several mounting holes and the limiting groove. The screw is fixed through the preset mounting holes, providing a mounting base for the rotating limiting block. The screw securely connects the rotating limiting block to the rotating shaft seat, preventing the rotating limiting block from falling off or loosening. The limiting groove cooperates with the limiting protrusion at the bottom of the rotating limiting block to form a mechanical limiting structure, preventing the rotating limiting block from rotating during rotation, thereby causing the rotating limiting block to be again limited in relation to the inner cavity of the mounting slide rail. After the rotating limiting block rotates, it contacts the inner cavity of the mounting slide rail, restricting the horizontal movement of the rotating shaft seat. Attached Figure Description

[0026] 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.
[0027] like Figure 1 and Figure 7As shown, in this embodiment, the present invention includes a rotating shaft seat 1 and a mounting slide rail 2. The rotating shaft seat 1 is slidably fitted on the mounting slide rail 2. The rotating shaft seat 1 includes at least one screw 3 and at least one rotation limiting block 4. The rotating shaft seat 1 is provided with at least one mounting hole. The screw 3 passes through the mounting hole and is fixedly connected to the rotation limiting block 4. The rotation limiting block 4 is limitedly fitted with the inner cavity of the mounting slide rail 2. The rotation limiting block 4 is provided with a limiting part 40 on the side of the rotating shaft seat 1 near the rotating shaft seat 1. The rotating shaft seat 1 is provided with a mating part 10 that is slidably fitted with the limiting part 40. Therefore, the rotating shaft seat 1 serves as a rotational support and sliding body. The rotating shaft seat 1 and the mounting slide rail 2 form a sliding connection, allowing the rotating shaft seat 1 to move axially along the mounting slide rail 2 to achieve position adjustment. The rotating shaft seat 1 provides mounting holes and mating parts 10 for installation. The screw 3 is fixed through the preset mounting holes, providing a mounting base for the rotating limit block 4. The rotating limit block 4 is threadedly fitted with the end of the screw 3, and the screw 3 securely connects the rotating limit block 4 to the rotating shaft seat. The mating parts 10 cooperate with the limiting parts 40 at the bottom of the rotating limit block 4 to form a mechanical limiting structure, preventing the rotating limit block 4 from rotating during rotation. This prevents the rotating limit block 4 from being again limited by the inner cavity of the mounting slide rail 2. After the rotating limit block 4 rotates, it contacts the inner cavity of the mounting slide rail 2, restricting the horizontal movement of the rotating shaft seat 1.
[0028] Furthermore, in this embodiment, the rotating shaft seat 1 is provided with a stop threaded hole 11, which is used to install a stop screw. The rotating shaft seat 1 is stopped on the mounting slide rail 2 by the stop screw. Thus, the rotating shaft seat 1 provides support and limits for the stop screw through the stop threaded hole 11. The stop screw contacts the stop mating surface of the mounting slide rail 2, generating friction or mechanical engagement, preventing the rotating shaft seat 1 from sliding further along the slide rail. Simultaneously, by adjusting the screwing depth of the stop screw 5, the axial position of the rotating shaft seat 1 on the mounting slide rail 2 can be precisely controlled, achieving fine-tuning and fixing of the position.
[0029] Preferably, in this embodiment, the limiting part 40 is a limiting protrusion, and the mating part 10 is a limiting groove. Thus, the limiting part 40 serves as an active limiting component, and the mating part 10 acts as a guide, providing movement guidance and limiting for the rotating limiting protrusion.
[0030] Optionally, in this embodiment, the limiting part 40 is a limiting groove, and the mating part 10 is a limiting protrusion. Thus, the mating part 10 serves as an active limiting component, and the limiting part 40 acts as a guide, providing movement guidance and limiting for the rotating limiting protrusion.
[0031] Furthermore, in this embodiment, the inner cavity cross-section of the mounting slide rail 2 is a trapezoidal design. Therefore, the inclined surfaces on both sides of the inner cavity of the mounting slide rail 2 can form a natural guide rail. When the rotating shaft seat 1 slides along the slide rail, the contact point between the inclined surface and the rotation limiting block 4 will generate a radial force, automatically guiding the rotating shaft seat 1 to the center of the slide rail, reducing offset caused by machining errors or assembly deviations. Moreover, the trapezoidal cross-section has higher bending stiffness than a rectangular cross-section. When subjected to lateral loads, the inclined sides of the trapezoid can disperse stress concentration, reducing the risk of slide rail deformation.
[0032] Furthermore, in this embodiment, the screw 3 is an internal hex socket screw. It is evident that internal hex socket screws require specialized tools for removal. Compared to ordinary screwdrivers, internal hex wrenches provide greater tightening torque, improving the screw's anti-loosening capability, reducing the risk of loosening due to vibration or external force, enhancing structural reliability, preventing unauthorized disassembly, and improving equipment safety.
[0033] Furthermore, in this embodiment, a rounded corner is provided on one side of the rotation limiting block 4. Therefore, the rotation limiting block 4, with its rectangular cross-section, has high bending stiffness and can withstand large loads without deformation. The rounded corner reduces the contact area between the limiting block and the inner cavity of the slide rail, thereby reducing sliding friction resistance and lowering the risk of jamming.
[0034] Furthermore, in this embodiment, the rotating limiting block 4 is fixedly fitted to the end of the screw 3 using strong adhesive. Therefore, the use of strong adhesive for curing has advantages such as fast speed and no need for specialized equipment. For low-cost consumer products, it reduces manufacturing costs, and the use of strong adhesive keeps the surface of the parts clean, making it suitable for scenarios with high aesthetic requirements.
[0035] Furthermore, in this embodiment, the rotating limiting block 4 is fixedly fitted to the end of the screw 3 by spot welding. Therefore, the structure fixed by spot welding has higher strength. Spot welding forms a metallurgical bond through metal melting, which can withstand high-frequency impacts and high-temperature environments, ensuring the long-term stability of the rotating limiting block 4.
[0036] Furthermore, in this embodiment, the rotation path on the mating part 10 is 0° to 180°. Therefore, both counterclockwise and clockwise rotation of the rotation limiting block 4 can cause the rotation limiting block 4 to no longer be in a limiting fit with the mounting slide rail 2, greatly improving the efficiency of disassembly.
[0037] The working principle of this utility model is as follows:
[0038] Before use, the mounting slide rail 2 is fixedly engaged. Then, the rotating shaft seat 1 is slid into the mounting slide rail 2. After reaching the designated position, the operator turns the screw 3 with an Allen wrench, which causes the rotating limit block 4 to engage with the inner cavity of the mounting slide rail 2, so that the rotating shaft seat 1 is first horizontally limited, and then the stop screw is turned to completely limit the rotating shaft seat 1.
[0039] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0040] The above embodiments do not limit the scope of protection of this utility model. All equivalent modifications and variations made by those skilled in the art without departing from the overall concept of this utility model shall still fall within the scope of this utility model.
