Description

Technical Field

[0001] This utility model relates to the field of quick assembly and disassembly technology, specifically a mechanism for quick assembly and disassembly of products. Background Technology

[0002] During the production, testing, and use of mass-produced products, those with bottom flanges often require frequent fixing and disassembly in various environments, such as vehicles or indoors. Traditional methods rely primarily on screw fixing, which, while reliable, requires multiple tightening and loosening of screws, resulting in lengthy individual operation times. This cumulative delay, especially on mass production lines, significantly extends the overall production cycle and impacts efficiency. Existing fixing mechanisms typically use rigid clips or mounting grooves to match the flange, but these designs struggle to accommodate subtle differences in flange outer diameter and height. Even slight deviations in product dimensions necessitate adjustments to the entire mechanism or replacement of parts, making the process complex and inflexible. Furthermore, during rotational fixing, relative sliding friction can occur between the product's bottom surface and the base surface, causing surface scratches or wear, thus affecting the product's appearance and functional reliability. To address these issues, a simple fixing mechanism is urgently needed that can achieve rapid positioning through controllable sliding and rotation, while avoiding unnecessary frictional contact, thereby improving assembly and disassembly efficiency and protecting product integrity. Utility Model Content

[0003] The purpose of this invention is to provide a simple fixing mechanism that can achieve rapid positioning through controllable sliding and rotation, while avoiding unnecessary frictional contact, thereby improving assembly and disassembly efficiency and protecting product integrity.

[0004] To achieve the above objectives, this utility model proposes the following technical solution: a mechanism for quick assembly and disassembly of products, comprising: A base, on which a support column is fixedly connected; A rotating disk is movably connected to a support column via a bearing. An arc-shaped hole is provided on the rotating disk, and a movable latch is provided on the arc-shaped hole. A fixed ring is fixedly connected to a support column. The rotating disk slides within the fixed ring. A strip-shaped hole is provided on the fixed ring. When the rotating disk rotates, it causes the movable lock to slide on the strip-shaped hole.

[0005] Furthermore, in this utility model, the movable latch includes a column, a support platform, a threaded column, and a clamping nut. The column is fixedly connected to the bottom of the threaded column, the clamping nut is threadedly connected to the threaded column, the support platform is fixedly connected to the column, and the support platform is used to support the movable latch on the arc-shaped hole. The threaded column passes through the strip-shaped hole.

[0006] Furthermore, this utility model also includes a plum blossom-shaped rotary locking device, which is threadedly connected to the fixing ring and disposed on the side of the fixing ring. The plum blossom-shaped rotary locking device is used to lock the rotating disc.

[0007] Furthermore, this utility model also includes a handle, which is fixedly connected to the bottom of the rotating disk, and the handle is Z-shaped.

[0008] Furthermore, in this utility model, the base, support column, rotating disk, fixing ring, and handle are all made of polyoxymethylene (POM) material.

[0009] Furthermore, in this utility model, the number of the arc-shaped hole, the strip-shaped hole, and the movable latch are all three, and they are centrally symmetrical about the support column.

[0010] Beneficial effects: The technical solution of this application has the following technical effects: This utility model provides a mechanism for quick product assembly and disassembly. Through the connection between the fixed support column on the base and the bearing of the rotating disk, smooth rotation is achieved, avoiding the time-consuming process of repeated screw tightening. Locking is completed with only unidirectional rotation, significantly shortening the production and testing cycle and improving overall efficiency. The mechanism incorporates a linkage design between the strip-shaped hole in the fixing ring and the arc-shaped hole in the rotating disk. The movable locking buckle can slide flexibly radially and axially, effectively adapting to flange sizes with different outer diameters and heights. This ensures stable fixing under various product specifications without the need for additional tools or adjustments, enhancing the mechanism's versatility and ease of operation.

[0011] Furthermore, the enclosed structure of the rotating disk sliding within the fixed ring keeps the bottom surface of the product separated from the base surface, avoiding direct frictional contact during rotation and protecting the product surface from scratches. At the same time, the use of internal bearings further reduces rotational resistance, making operation easier and suitable for high-frequency assembly and disassembly scenarios.

[0012] It should be understood that all combinations of the foregoing concepts and the additional concepts described in more detail below can be considered as part of the utility model subject matter of this disclosure, provided that such concepts do not contradict each other.

[0017] like Figure 1-6 As shown, this embodiment provides a mechanism for quick assembly and disassembly of products. This mechanism is suitable for fixing and disassembling products with bottom flanges during production, testing, and use, and is particularly suitable for various environments such as vehicle-mounted or indoor environments. In this embodiment, all components are made of polyoxymethylene (POM) material, which has high strength and wear resistance, ensuring the mechanism maintains stability and durability during frequent operation. The specific structure is as follows: The base 1, serving as the bottom support component of the entire mechanism, is disc-shaped with a flat bottom surface, facilitating fixation to the vehicle floor or indoor workbench via screws or adhesive. Its primary purpose is to provide a stable mounting foundation, preventing displacement due to vibration or external forces during use, thereby improving overall stability. A support column 2 is fixedly connected to the top center of the base 1. The support column 2 is a hollow cylindrical structure of moderate height, serving as axial support for rotating components, ensuring smooth rotation of the rotating disk 3 around its axis. Internal space is reserved to accommodate bearing assemblies, improving the smoothness and ease of rotation. A retaining ring 4 is fixedly connected to the upper end of the support column 2 via an embedded connection. The retaining ring 4 has an annular structure with an inner diameter slightly larger than the outer diameter of the rotating disk 3. Its main purpose is to limit the axial displacement and radial wobble of the rotating disk 3, forming a closed sliding track to ensure no loosening or detachment of components during rotation.

[0018] Three strip-shaped holes 401 are evenly provided on the side wall of the fixing ring 4. These strip-shaped holes 401 are distributed along the circumference and are centrally symmetrical about the support column 2. The length direction points to the center of the fixing ring 4. Its advantage is that it allows the movable latch 5 to slide radially when rotating, thereby adapting to flanges 9 with different outer diameters. This avoids the strict limitation of product size on traditional fixing mechanisms and improves the versatility of the mechanism.

[0019] The rotating disk 3 has a disc-shaped, thin-walled structure. Its center is movably connected to the outer surface of the support column 2 via a 61822 deep groove ball bearing. The inner ring of the bearing is fixed to the support column 2, and the outer ring is fixed in the central hole of the rotating disk 3. This design provides low-friction rotational support, minimizing the rotational torque of the handle 7, making operation easier and smoother, and avoiding the fatigue of manually tightening screws. Three arc-shaped holes 301 are formed along the circumference of the upper surface of the rotating disk 3. These arc-shaped holes 301 are also centrally symmetrical about the support column 2, and their curvature matches the rotation range of the rotating disk 3. This design guides the arc-shaped movement of the movable locking buckle 5, ensuring that the flange 9 is evenly clamped during locking, preventing product tilting or uneven force.

[0020] The movable locking buckle 5 is the core component for locking the flange 9. It includes a column 501, a support platform 502, a threaded column 503, and a clamping nut 504. The column 501 is a cylindrical protrusion, fixedly connected to the bottom end face of the threaded column 503, achieving a rigid connection through integral molding or welding. The support platform 502 is an annular platform, fixedly connected to the column 501, and its purpose is to place the movable locking buckle 5 on the upper surface of the rotating disk 3. The arc-shaped hole 301 supports the movable locking buckle 5, which has the advantage of preventing the movable locking buckle 5 from dislodging from the track during rotation. The threaded post 503 extends upward from the post body 501, passing through the slotted hole 401 of the fixing ring 4. Its threaded portion is threadedly connected to the clamping nut 504, which is located above the fixing ring 4. The axial height of the movable locking buckle 5 is controlled by rotating and adjusting its position. The clamping nut 504 can clamp the flange 9, thus allowing for fine-tuning to match flanges 9 of different heights. This connection ensures quick adjustment and stable fixation of the locking buckle, avoids reliance on additional tools, and improves operational efficiency. The three movable locking buckles 5 are evenly distributed on the rotating disk 3, each adjustable independently, but are synchronously locked through the linkage of the rotating disk 3.

[0021] To enhance the stability of the locking state, the side of the fixed ring 4 is threadedly connected to the plum blossom-shaped rotary locking device 6 through a threaded hole. The plum blossom-shaped rotary locking device 6 has a multi-lobed cam structure, and its axis is installed vertically on the side wall of the fixed ring 4. Its purpose is to press the surface of the rotating disk 3 by clockwise screwing it in after the rotating disk 3 has rotated into place, preventing it from loosening in the opposite direction and improving the reliability of the mechanism in a vibration environment.

[0022] The handle 7 is a Z-shaped curved rod-like component. One end is fixedly connected to the bottom center of the rotating disk 3 by screws or pins, and its free end extends to a position easily accessible to the operator. Its advantage is that it provides sufficient leverage torque, making it easy to operate with one hand. At the same time, the Z-shaped design avoids interference with the base 1 and ensures sufficient rotation space.

[0023] The working principle of this embodiment is as follows: First, the product with the bottom flange 9 is placed on the upper surface of the fixing ring 4. The handle 7 is rotated to drive the rotating disk 3 to rotate, thereby adjusting the position of each movable locking buckle 5. Then, the clamping nut 504 is pressed down through the threaded post 503 to match the height and outer diameter of the flange 9, ensuring that the nut 504 is evenly attached to the outer edge of the flange 9, achieving progressive clamping of the flange 9. During the locking process, the bottom surface of the product 8 remains stationary with the fixing ring 4 to avoid friction damage. After rotating to the correct position, the plum blossom-shaped rotary locking device 6 is tightened clockwise, which presses against the surface of the rotating disk 3 to lock the position and prevent rotation. For disassembly, the plum blossom-shaped rotary locking device 6 is first unscrewed counterclockwise to release the rotating disk 3, and then the handle 7 is turned counterclockwise, causing the movable locking buckles 5 to release, achieving rapid separation. This process only takes a few seconds, significantly shortening the disassembly and assembly time.
