Description

Technical Field

[0001] This utility model relates to the field of fastener technology, specifically to an anti-loosening fastening component. Background Technology

[0002] In the application of modern video equipment, the installation and fixation of cameras are crucial to ensuring their normal operation. Especially in scenarios requiring tripod support, the stability of the camera directly affects the shooting effect and the safety of the equipment. However, existing camera installation methods generally suffer from poor fastening. After the camera is mounted on the tripod, the weight of the camera itself or external vibrations can easily cause the connection points to loosen. This loosening not only affects the camera's shooting angle and stability but may also cause the camera to fall off the tripod, leading to equipment damage or safety accidents. Furthermore, existing fastening components are usually simple in structure and lack effective anti-loosening designs, making it difficult to maintain a reliable connection during long-term use. Therefore, developing a component that can effectively prevent loosening and improve fastening reliability has become an urgent technical problem to be solved. This utility model aims to provide an anti-loosening fastening component to overcome the shortcomings of the existing technology and meet practical application needs. Utility Model Content

[0003] This utility model addresses the problem of camera loosening and detachment caused by poor fastening after mounting on a tripod in existing technologies. To solve this, the utility model adopts the following technical solution: an anti-loosening fastening assembly, including a base, a connector, a support rod, a mounting base, and a fastening mechanism. The base serves as the foundation of the entire assembly, with multiple legs extending from its lower part to provide stability. The connector is fixed to the base and achieves initial anti-loosening function through a slot and a limiting plate. The support rod connects the connector and the mounting base, used for adjusting height and angle. The mounting base is used to fix the camera. The fastening mechanism is located between the base and the connector, further enhancing the overall structural stability.

[0004] This utility model provides an anti-loosening fastening assembly, wherein the base is made of high-strength material, and its upper surface has threaded holes for connection with a plug-in socket. Three or four legs are evenly distributed on the lower part of the base, and each leg has a rubber pad at its end to increase friction and reduce vibration transmission. Specifically, the legs can be rotated to adjust their length, thereby adapting to the needs of different terrain conditions. Furthermore, a metal frame is embedded inside the base to enhance compressive strength while reducing overall weight.

[0005] Furthermore, the connector is fixed to the base by bolts, and its outer side is provided with an annular groove for engaging with a locking block in the fastening mechanism. The top of the connector has a support rod connection interface, the inner wall of which is machined with internal threads to form a tight connection with the external threads at the bottom of the support rod. Specifically, a limiting plate is provided on one side of the connector, with a through hole to allow the support rod to rotate within a certain range but prevent it from completely disengaging. Furthermore, a positioning pin is provided at the bottom of the connector, which is inserted into a positioning hole on the base to prevent horizontal displacement of the connector.

[0006] Furthermore, the support rod is a hollow cylindrical structure, with its two ends connected to the plug-in socket and the mounting base, respectively. A locking device is provided in the middle of the support rod, comprising a knob and a clamping sleeve. Rotating the knob causes the clamping sleeve to retract, thereby fixing the position of the support rod. Specifically, the support rod has an internal damping structure made of elastic material to absorb external vibration energy and reduce its impact on the mounting base. Furthermore, the outer surface of the support rod has graduation marks for precisely adjusting the height of the camera.

[0007] Furthermore, the mounting base is a rectangular frame structure with multiple mounting holes on its upper surface for fixing the camera. The bottom of the mounting base has a ball joint that embeds into a socket at the top of the support rod and is secured in position by a locking nut. Specifically, the mounting base has auxiliary fixing components on its side, which are connected to the mounting base via springs to further enhance the camera's stability. Furthermore, the mounting base contains shock-absorbing pads made of polymer material to absorb high-frequency vibrations.

[0008] Furthermore, the fastening mechanism includes a U-shaped frame, a fixed rod, a limiting ring, a support plate, a rotating shaft, an L-shaped rotating block, a return spring, a locking block, a screw, a threaded post, and a limiting plate. The U-shaped frame is fixed above the base, and the two arms of the U-shaped frame are connected to the base via a fixed rod. A limiting ring is fitted on the fixed rod to restrict its range of movement. Specifically, a support plate is provided on the inner side of the U-shaped frame, and the support plate is connected to the L-shaped rotating block via a rotating shaft. The L-shaped rotating block can rotate freely on the rotating shaft. Furthermore, a return spring is provided between the L-shaped rotating block and the support plate. One end of the return spring is fixed to the L-shaped rotating block, and the other end is fixed to the support plate, so that the L-shaped rotating block always tends to return to its initial position.

[0009] Furthermore, the locking block is fixed to the end of the L-shaped rotating block, and the shape of the locking block matches the slot on the connector. When the L-shaped rotating block rotates, the locking block can be inserted into the slot to prevent the connector from becoming loose. Specifically, the screw passes through the top of the U-shaped frame and is threadedly connected to the threaded post. By rotating the screw, the vertical position of the threaded post can be adjusted, thereby changing the angle of the L-shaped rotating block. Furthermore, a limiting plate is provided at the top of the screw, which is fixed to the screw by a screw to limit the maximum rotation angle of the screw to prevent over-adjustment.

[0010] Specifically, the working process of the fastening mechanism is as follows: S1, the operator fixes the plug-in seat on the base, at which time the slot of the plug-in seat is aligned with the locking block in the fastening mechanism; S2, the screw is rotated, causing the threaded column to move upward, pushing the L-shaped rotating block to rotate around the axis; S3, the L-shaped rotating block drives the locking block to insert into the slot of the plug-in seat, and at the same time the return spring is compressed; S4, when the locking block is fully inserted into the slot, the screw is stopped from rotating and its position is locked with a limiting piece; S5, if it is necessary to release the fastening state, the screw is rotated in the opposite direction, the return spring pushes the L-shaped rotating block to reset, and the locking block is removed from the slot.

[0011] The beneficial effects of this invention are as follows: The combination of the base and the support legs provides a solid supporting foundation, effectively preventing loosening caused by external vibration or gravity. Furthermore, the combination of the slot and the limiting plate on the connector, along with the synergistic action of the locking block and the return spring in the fastening mechanism, forms a multi-level anti-loosening mechanism, significantly improving the anti-loosening capability of the fastening assembly. In particular, the combination of the rotating shaft and the L-shaped rotating block allows users to easily adjust the camera angle to meet the needs of different scenarios. Furthermore, the combination of the screw and the threaded post enables precise fastening adjustment, while the limiting plate prevents over-operation, ensuring the long-term reliability of the assembly. In addition, this fastening assembly is not only suitable for camera installation but can also be extended to other equipment fixing scenarios requiring high stability and anti-loosening performance.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] This utility model provides an anti-loosening fastening component, combined with Figures 1 to 4 The structural schematic diagram and partial disassembly diagram shown illustrate the specific implementation method. The anti-loosening fastening component in this embodiment is mainly used for fixing the camera to the tripod, but it is also suitable for other equipment fixing scenarios requiring high stability and anti-loosening performance.

[0021] like Figure 1 As shown, the entire anti-loosening fastening assembly includes a base 11, a connector 21, a support rod 22, a mounting base 23, and a fastening mechanism 3. The base 11, as the foundation of the entire assembly, provides solid support for the overall structure. The base 11 is made of high-strength aluminum alloy, and its upper surface has multiple threaded holes for connection with the connector 21. Three legs 12 are evenly distributed at the bottom of the base 11, each with a rubber pad at its end. The rubber pads are fixed to the bottom of the leg 12 with screws to increase friction and reduce the impact of external vibrations on the assembly. The legs 12 are designed for adjustable length by rotating the threaded sleeves on them, thus adapting to different terrain conditions. Furthermore, a metal frame made of steel is embedded inside the base 11, enhancing its compressive strength while reducing overall weight.

[0022] The connector 21 is bolted to the base 11, and has an annular groove 211 on its outer side for engaging with the locking block 306 in the fastening mechanism 3. The top of the connector 21 has a support rod connection interface with internal threads machined into its inner wall, forming a tight connection with the external threads at the bottom of the support rod 22. To prevent the support rod 22 from completely detaching from the connector 21, a limiting plate 212 is provided on one side of the connector 21. The limiting plate 212 has a through hole, allowing the support rod 22 to rotate within a certain range but preventing it from detaching. A positioning pin is also provided at the bottom of the connector 21, which inserts into a positioning hole on the base 11 to ensure that the connector 21 does not shift horizontally. This multi-stage fixing design effectively improves the connection stability between the connector 21 and the base 11.

[0023] The support rod 22 is a hollow cylindrical structure, with its two ends connected to the insertion socket 21 and the mounting base 23, respectively. A locking device is located in the middle of the support rod 22, comprising a knob and a clamping sleeve. Rotating the knob retracts the clamping sleeve, thus fixing the position of the support rod 22. The support rod 22 has an internal damping structure made of silicone material, which absorbs external vibration energy and reduces the impact on the mounting base 23. Furthermore, the outer surface of the support rod 22 has graduated markings, allowing users to precisely adjust its height to meet the needs of different camera installation scenarios.

[0024] Mounting base 23 has a rectangular frame structure with multiple mounting holes on its upper surface for fixing camera 24. A ball joint is located at the bottom of mounting base 23, which fits into a socket at the top of support rod 22 and is secured in position by a locking nut. Auxiliary fixing components are located on the sides of mounting base 23, connected to mounting base 23 via springs to further enhance the fixation of camera 24. Internally, mounting base 23 contains shock-absorbing pads made of polyurethane material, which absorb high-frequency vibrations and protect camera 24 from external vibration interference. This multi-layered fixing design ensures that camera 24 remains stable during operation.

[0025] The fastening mechanism 3 is the core component of this invention, and its main function is to further enhance the stability of the connection between the base 11 and the insertion seat 21. The fastening mechanism 3 includes a U-shaped frame 301, a fixing rod 310, a limiting ring 311, a support plate 302, a rotating shaft 303, an L-shaped rotating block 304, a return spring 305, a locking block 306, a screw 307, a threaded post 308, and a limiting piece 309. The U-shaped frame 301 is fixed above the base 11. The two arms of the U-shaped frame 301 are connected to the base 11 via the fixing rod 310. The limiting ring 311 is fitted onto the fixing rod 310, restricting the range of movement of the fixing rod 310 and ensuring that the U-shaped frame 301 is always in the correct position. A support plate 302 is provided inside the U-shaped frame 301. The support plate 302 is connected to the L-shaped rotating block 304 via the rotating shaft 303, allowing the L-shaped rotating block 304 to rotate freely on the rotating shaft 303. A reset spring 305 is provided between the L-shaped rotating block 304 and the support plate 302. One end of the reset spring 305 is fixed on the L-shaped rotating block 304 and the other end is fixed on the support plate 302, so that the L-shaped rotating block 304 always tends to reset to the initial position.

[0026] A locking block 306 is fixed to the end of the L-shaped rotating block 304, and the shape of the locking block 306 matches the slot 211 on the connector 21. When the L-shaped rotating block 304 rotates, the locking block 306 can be inserted into the slot 211, thereby preventing the connector 21 from becoming loose. A screw 307 passes through the top of the U-shaped frame 301 and is threadedly connected to a threaded post 308. By rotating the screw 307, the up and down position of the threaded post 308 can be adjusted, thereby changing the angle of the L-shaped rotating block 304. A limiting piece 309 is provided at the top of the screw 307. The limiting piece 309 is fixed to the screw 307 by screws to limit the maximum rotation angle of the screw 307 and prevent over-adjustment from causing structural damage.

[0027] The working process of the fastening mechanism 3 is as follows: S1, the operator fixes the plug-in seat 21 on the base 11, at which time the slot 211 of the plug-in seat 21 is aligned with the locking block 306 in the fastening mechanism 3; S2, the screw 307 is rotated, causing the threaded post 308 to move upward, pushing the L-shaped rotating block 304 to rotate around the rotating shaft 303; S3, the L-shaped rotating block 304 drives the locking block 306 to insert into the slot 211 of the plug-in seat 21, and at the same time the return spring 305 is compressed; S4, when the locking block 306 is fully inserted into the slot 211, the screw 307 is stopped and its position is locked with the limiting piece 309; S5, if it is necessary to release the fastening state, the screw 307 is rotated in the opposite direction, the return spring 305 pushes the L-shaped rotating block 304 to reset, and the locking block 306 is removed from the slot 211.

[0028] This invention has a wide range of applications. For example, in outdoor monitoring systems, the camera 24 often needs to be fixed on a tripod for extended periods. Traditional fixing methods are prone to loosening or even detachment due to wind or vibration. However, with the anti-loosening fastening component of this invention, the combination of the base 11 and the support leg 12 provides a solid support foundation, effectively preventing loosening caused by external vibration or gravity. The slot 211 on the connector 21 cooperates with the limiting plate 212, and the synergistic action of the locking block 306 and the return spring 305 in the fastening mechanism 3 forms a multi-level anti-loosening mechanism, significantly improving the fastening component's resistance to loosening. Furthermore, through the cooperation of the rotating shaft 303 and the L-shaped rotating block 304, users can easily adjust the angle of the camera 24 to meet the needs of different scenarios. The combination of the screw 307 and the threaded post 308 achieves precise fastening adjustment, while the limiting plate 309 prevents over-operation, ensuring the long-term reliability of the component.

[0029] In practice, users can quickly install and adjust the anti-loosening fastening components as needed. For example, when adjusting the height of the camera 24, the user simply rotates the knob on the support rod 22, adjusting the tightness of the clamping sleeve to achieve the height change. When adjusting the angle of the camera 24, the user loosens the locking nut on the mounting base 23, adjusts the position of the ball joint, and then re-locks it to complete the angle adjustment. This flexible design makes this invention not only suitable for camera installation but also extendable to other equipment fixing scenarios requiring high stability and anti-loosening performance.

[0030] In summary, the anti-loosening fastening assembly provided by this utility model solves the problem of loosening and detachment caused by poor fastening effect after the camera is installed on the tripod in the prior art through multi-layered anti-loosening design and precise adjustment function. Its unique structural design and efficient anti-loosening mechanism enable it to exhibit excellent performance in various application scenarios and have broad market application prospects.
