[0027] Example

[0028] The step-type ball-matching mechanism provided in this embodiment, such as Figures 1-5 As shown, it includes: a cylindrical outer shell 1, a ball 2, and a spring 3. One end of the cylindrical outer shell 1 is an open end, and the other end of the cylindrical outer shell 1 is a closed end. An annular groove 101 is provided on the inner side of the open end of the cylindrical outer shell 1, and an annular retaining ring 103 is integrally provided on the outer side of the open end of the cylindrical outer shell 1. The annular retaining ring 103 is used to prevent the entire ball from falling into the mounting hole when the ball is installed, thereby improving the installation stability of the ball.

[0029] To prevent the ball 2 from falling out, the ball 2 is rotatably secured in the annular groove 101, with the ball 2 protruding from the annular groove 101 away from the cylindrical outer shell 1. To provide support for the ball 2 and improve its stability, the spring 3 is installed inside the cylindrical outer shell 1. To further improve the stability of the spring 3, a T-shaped guide block 301 is inserted into one end of the spring 3, and a support block 302 is integrally provided at the end of the T-shaped guide block 301 away from the spring 3. The side of the support block 302 is fitted to the inner wall of the cylindrical shell 1. The end face of the support block 302 away from the T-shaped guide block 301 has an arc-shaped groove. The inner wall of the arc-shaped groove of the support block 302 is abutted and fitted to the surface of the ball 2. The end of the spring 3 away from the T-shaped guide block 301 is abutted to the inner wall of the closed end of the cylindrical shell 1. The end of the spring 3 away from the T-shaped guide block 301 is inserted into the limiting sleeve 303. The limiting sleeve 303 is fixedly installed on the inner wall of the closed end of the cylindrical shell 1.

[0030] The stepped ball bearing using the above technical solution mainly consists of a cylindrical outer shell 1, a ball 2, and a spring 3. Under the action of the annular groove 101, the ball 2 can be prevented from detaching from the cylindrical outer shell 1, so that the ball 2 can be stably rotated and positioned within the annular groove 101. At the same time, the spring 3 provides continuous elastic support for the ball 2, enabling it to rotate flexibly and reset under the action of external force. This design improves the adaptability, durability, and stability of the positioning ball, and is suitable for various occasions that require positioning or guidance.

[0031] Meanwhile, under the action of the T-shaped guide block 301, the support block 302 and the limiting sleeve 303, the spring 3 can stably provide effective support for the ball 2, which can further improve the overall stability of the step ball collision.

[0032] Specifically, in this embodiment, a through hole 102 is provided in the center of the closed end of the cylindrical outer shell 1. The through hole 102 is used for venting and draining oil stains to improve the stability of the step ball.

[0033] Specifically, in this embodiment, in order to improve the corrosion resistance and durability of the cylindrical outer shell 1, the cylindrical outer shell 1 is made of stainless steel, which has the advantages of being less prone to deformation and having a long service life.

[0034] Specifically, in this embodiment, in order to ensure the service life of the ball 2, the ball 2 is made of steel.

[0035] Specifically, in this embodiment, in order to ensure the service life of spring 3, spring 3 is made of stainless steel.

[0036] Specifically, in this embodiment, in order to improve safety and aesthetics, the outer edge of the closed end of the cylindrical shell 1 and the outer edge of the annular retaining ring 103 are both rounded.

[0037] In summary, the stepped ball-matching mechanism provided in this embodiment has the following advantages:

[0038] The step-mounted ball provided in this embodiment uses a combination design of a cylindrical outer shell 1, a ball 2, and a spring 3. Under the action of the annular groove 101, the ball 2 can be prevented from detaching from the cylindrical outer shell 1, allowing the ball 2 to be stably rotated and positioned within the annular groove 101. At the same time, under the action of the T-shaped guide block 301, the support block 302, and the limiting sleeve 303, the spring 3 can stably provide effective support for the ball 2, which can further improve the overall stability of the step-mounted ball. This allows the ball 2 to rotate flexibly and reset under the action of external force. This design improves the adaptability, durability, and stability of the positioning ball, and is suitable for various furniture accessories and automotive accessories.

[0039] Working principle:

[0040] Cylindrical outer shell 1: As the main structure of the stepped ball-bearing mechanism, one end is open for mounting the ball 2 and spring 3; the other end is closed, with a through hole 102 in the center for venting and draining oil, improving stability. An annular groove 101 is formed on the inner side of the open end of the cylindrical outer shell 1 to hold the ball 2 in place and prevent it from falling out. An annular retaining ring 103 is integrally formed on the outer side of the open end of the cylindrical outer shell 1 to prevent the entire assembly from falling into the mounting hole during installation, improving installation stability. The cylindrical outer shell 1 is preferably made of stainless steel, which has the advantages of being resistant to deformation and having a long service life.

[0041] 2. The ball 2 is rotatably engaged in the annular groove 101, with one end facing away from the cylindrical outer shell 1 protruding from the annular groove 101 to contact external objects and achieve a positioning function. The ball 2 is preferably made of steel ball to improve its hardness and wear resistance.

[0042] Spring 3: Spring 3 is installed inside the cylindrical outer shell 1 to provide continuous and stable elastic support for the ball 2. A T-shaped guide block 301 is inserted into one end of spring 3. A support block 302 is integrally formed at the end of the T-shaped guide block 301 away from spring 3. The inner wall of the arc-shaped groove of the support block 302 abuts and fits against the surface of the ball 2. The other end of spring 3 abuts against the inner wall of the closed end of the cylindrical outer shell 1 and is limited by a limiting sleeve 303 to ensure the stability and durability of spring 3. Spring 3 is preferably made of stainless steel to improve its corrosion resistance and durability.

[0043] Working process: When an external force is applied to ball 2, ball 2 rotates within the annular groove 101. Simultaneously, spring 3 provides elastic support to ball 2 through T-shaped guide block 301 and support block 302, enabling it to rotate flexibly and return to its original position. When the external force disappears, the elastic force of spring 3 returns ball 2 to its initial position, achieving the positioning function.

[0044] In summary, the step-type ball bearing provided in this embodiment improves overall stability, adaptability, and durability through optimized structural design, making it suitable for various occasions requiring positioning or guidance.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
