Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware materials technology, and in particular to a self-locking mechanism for a two-wheeled vehicle adjusting nut. Background Technology
[0002] The adjusting nut on a two-wheeled vehicle is used to adjust the position or status of certain components. During actual use, the adjusting nut is easily loosened by vibration or external forces. Over time, this loosening may cause the adjusting component to change position or even detach completely, potentially affecting the normal use of the two-wheeled vehicle, reducing its performance, shortening its lifespan, increasing maintenance and repair costs, extending downtime, affecting equipment efficiency, and even creating safety hazards.
[0003] Existing self-locking structures for adjusting nuts are often one-way locking designs, which prevent adjustment once locked. While this effectively prevents the adjusting nut from loosening due to vibration or external forces during use, thus improving safety and stability to some extent, the one-way locking design may not provide sufficient adjustment space when minor adjustments are needed. This affects the accuracy and convenience of adjustment, limiting the flexibility and precision of adjustment. Furthermore, if the nut cannot be rotated in the opposite direction, it may be necessary to completely remove it for readjustment, impacting work efficiency. Utility Model Content
[0004] To address the technical problem that the existing self-locking structure of adjusting nuts is inconvenient for adjustment, this utility model proposes a self-locking mechanism for adjusting nuts on two-wheeled vehicles.
[0005] This utility model proposes a self-locking mechanism for a two-wheeled vehicle adjusting nut, including an adjusting nut with an internal thread. The adjusting nut has a circumferential limit component, which includes an outer hole. A tool is inserted through the outer hole to release the self-locking state of the adjusting nut. The limit component contains a self-locking component, which includes a threaded block. The threaded block restricts the rotation of the bolt within the adjusting nut to achieve self-locking.
[0006] Preferably, the limiting component further includes an inner hole, and the outer hole and the inner hole are respectively opened on the outside and inside of the adjusting nut.
[0007] The above technical solution utilizes an outer hole and an inner hole to create openings on the outside and inside of the adjusting nut, facilitating the insertion of tools through the outer hole and locking the bolt rotation direction through the inner hole components.
[0008] Preferably, an arc-shaped groove connects the outer hole and the inner hole, and the two ends of the arc-shaped groove are respectively connected to the output end of the outer hole and the input end of the inner hole.
[0009] The above technical solution uses an arc-shaped groove to connect the outer and inner holes, which facilitates the support of internal components and restricts their movement.
[0010] Preferably, the self-locking assembly further includes a fixing rod, which is fixedly installed between the inner walls of the arc-shaped groove, and a balance frame is sleeved on the outside of the fixing rod.
[0011] The above technical solution utilizes an arc-shaped groove to support the fixed rod, facilitating the rotation of the balance frame around the fixed rod as a fulcrum.
[0012] Preferably, a movable block is fixedly connected to one end of the balance frame near the outer hole, and a rotating block is hinged to one end of the balance frame near the inner hole. The weight of the rotating block at the end away from the outer hole is greater than the weight at the other end. The bottom of the rotating block is fixedly connected to the top of the threaded block, and the thread at the bottom of the threaded block is matched with the internal thread of the adjusting nut.
[0013] The above technical solution utilizes rotating blocks with different masses on both sides. By different mass distributions, one side of the threaded block contacts the bolt, which facilitates normal operation of the adjusting nut when it rotates clockwise, and causes the threaded block to jam with the bolt's threads when it rotates counterclockwise.
[0014] Preferably, a fixing ring is fixedly connected to the outside of the fixing rod, and the fixing ring is disposed between the two sides of the balance frame.
[0015] The above technical solution utilizes a fixed rod to support the fixed ring, thus maintaining the stability of the fixed ring.
[0016] Preferably, a torsion spring is sleeved on the outside of the fixing rod, one end of the torsion spring is fixedly connected to one side of the fixing ring, and the other end of the torsion spring is fixedly connected to the inner wall of the balance frame.
[0017] The above technical solution utilizes a torsion spring to keep the rotating block always attached to the bolt. When the wheel rotates, the movable block moves outward along the outer hole under the action of centrifugal force, and the rotating block moves inward under the action of the balance bar, which facilitates tight contact between the threaded block and the bolt.
[0018] The beneficial effects of this utility model are as follows:
[0019] 1. By setting a limiting component, the outer hole and the inner hole are connected by an arc groove, which facilitates the support of the internal components and restricts their movement. It also makes it easy to insert tools from the outer hole, thereby loosening the self-locking structure of the adjusting nut, making it easy to make fine adjustments and improving work efficiency.
[0020] 2. By setting a self-locking component, the torsion spring keeps the rotating block always on the bolt. When the wheel rotates, the moving block moves outward along the outer hole under the action of centrifugal force. Under the action of the balance bar, the rotating block moves inward, which facilitates the tight contact between the threaded block and the bolt. The rotating blocks with different masses on both sides can make one side of the threaded block contact the bolt, which is convenient for the adjusting nut to operate normally when rotated clockwise. When rotated counterclockwise, the threaded block and the bolt threads are locked together, achieving a self-locking effect. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Reference Figures 1-3 A self-locking mechanism for a two-wheeled vehicle adjusting nut includes an adjusting nut 1, the adjusting nut 1 having an internal thread 2, and a limiting component circumferentially provided on the adjusting nut 1. The limiting component includes an outer hole 3, through which a tool is inserted to release the self-locking state of the adjusting nut 1. The limiting component is provided with a self-locking component, the self-locking component including a threaded block 4, which restricts the rotation of the bolt within the adjusting nut 1 to achieve self-locking.
[0027] To enable the limiting component to operate, the limiting component also includes an inner hole 5. The outer hole 3 and the inner hole 5 are respectively opened on the outside and inside of the adjusting nut 1. The outer hole 3 and the inner hole 5 open the outside and inside of the adjusting nut 1, respectively, to facilitate the insertion of tools through the outer hole 3. The inner hole 5 locks the rotation direction of the bolt. An arc-shaped groove 6 connects the outer hole 3 and the inner hole 5. The two ends of the arc-shaped groove 6 are respectively connected to the output end of the outer hole 3 and the input end of the inner hole 5. The arc-shaped groove 6 connects the outer hole 3 and the inner hole 5, which facilitates the support of the internal components and restricts the movement of the internal components.
[0028] By setting a limiting component, the outer hole 3 and the inner hole 5 are connected by the arc groove 6, which facilitates the support of the internal components and restricts their movement. It also makes it easy to insert tools from the outer hole 3, thereby loosening the self-locking structure of the adjusting nut 1, making it easier to make fine adjustments and improving work efficiency.
[0029] To enable the self-locking assembly to operate, the self-locking assembly further includes a fixing rod 7, which is fixedly installed between the inner walls of the arc-shaped groove 6. A balance frame 8 is sleeved on the outside of the fixing rod 7. The arc-shaped groove 6 supports the fixing rod 7, facilitating the rotation of the balance frame 8 around the fixing rod 7 as a fulcrum. A movable block 9 is fixedly connected to one end of the balance frame 8 near the outer hole 3, and a rotating block 10 is hinged to one end of the balance frame 8 near the inner hole 5. The weight of the rotating block 10 at the end away from the outer hole 3 is greater than the weight at the other end. The bottom of the rotating block 10 is fixedly connected to the top of the threaded block 4. The thread at the bottom of the threaded block 4 matches the internal thread 2 of the adjusting nut 1. The different masses on both sides of the rotating block 10 allow for rotation. The moving block 10, through different mass distribution, allows one side of the threaded block 4 to contact the bolt, facilitating normal operation when the adjusting nut 1 rotates clockwise, and locking the threaded block 4 with the bolt thread when rotated counterclockwise. A fixing ring 11 is fixedly connected to the outside of the fixing rod 7, and the fixing ring 11 is positioned between the two sides of the balance frame 8. The fixing rod 7 supports the fixing ring 11, maintaining its stability. A torsion spring 12 is sleeved on the outside of the fixing rod 7. One end of the torsion spring 12 is fixedly connected to one side of the fixing ring 11, and the other end is fixedly connected to the inner wall of the balance frame 8. The torsion spring 12 ensures that the rotating block 10 is always resting on the bolt. When the wheel rotates, the moving block 9 moves outward along the direction of the outer hole 3 under the action of centrifugal force. Under the action of the balance rod, the rotating block 10 moves inward, facilitating tight contact between the threaded block 4 and the bolt.
[0030] By setting a self-locking component, the torsion spring 12 keeps the rotating block 10 always attached to the bolt. When the wheel rotates, the movable block 9 moves outward along the direction of the outer hole 3 under the action of centrifugal force. Under the action of the balance bar, the rotating block 10 moves inward, which facilitates the threaded block 4 to make tight contact with the bolt. The rotating blocks 10 with different masses on both sides can make one side of the threaded block 4 contact the bolt, which facilitates the normal operation of the adjusting nut 1 when it rotates clockwise, and the threaded block 4 and the bolt thread jam when it rotates counterclockwise, thus achieving a self-locking effect.
[0031] Working principle:
[0032] By rotating the adjusting nut 1 with a tool, the adjusting nut 1 is tightened to the bolt. When the adjusting nut 1 is reversed, the threaded block 4 and the bolt are locked together to achieve self-locking. When it is necessary to adjust the tightness, insert the tool into the outer hole 3 and press down the movable block 9. The threaded block 4 will then be lifted, allowing the adjusting nut 1 to be reversed.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
