[0027] The plastic positioning bead using the above technical solution mainly consists of a cylindrical shell 1, a bead 2, and a spring 3. Under the action of the annular groove 101, the bead 2 can be prevented from detaching from the cylindrical shell 1, so that the bead 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 bead 2, allowing it to rotate flexibly and reset under the action of external force. This design improves the adaptability, durability, and stability of the positioning bead, and is suitable for various occasions that require positioning or guidance.

[0028] 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 plastic positioning bead.

[0032] Specifically, in this embodiment, in order to improve safety and aesthetics, the outer edges of both ends of the cylindrical outer shell 1 are rounded.

[0033] In summary, the plastic positioning bead provided in this embodiment has the following advantages:

[0034] The plastic positioning bead provided in this embodiment, through the combined design of a cylindrical shell 1, a bead 2, and a spring 3, can prevent the bead 2 from detaching from the cylindrical shell 1 under the action of the annular groove 101, so that the bead 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 bead 2, enabling it to rotate flexibly and reset under the action of external force. This design improves the adaptability, durability, stability, and positioning accuracy of the positioning bead, and is suitable for various occasions that require positioning or guidance.

[0035] Working principle:

[0036] Cylindrical outer shell 1: As the main structure of the positioning bead, one end of the cylindrical outer shell 1 is an open end for installing the bead 2 and the spring 3; the other end is a closed end for limiting the displacement of the spring 3. An annular groove 101 is provided on the inner side of the open end of the cylindrical outer shell 1 for holding the bead 2.

[0037] 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.

[0038] Spring 3: Spring 3 is installed inside the cylindrical outer shell 1, with one end abutting against the ball 2 and the other end abutting against the inner wall of the closed end of the cylindrical outer shell 1. Spring 3 provides continuous elastic support for the ball 2, allowing it to rotate flexibly and return to its original position under external force. Spring 3 is preferably made of stainless steel to improve its corrosion resistance and durability.

[0039] Working process: When an external force is applied to bead 2, bead 2 rotates within the annular groove 101, simultaneously compressing spring 3. When the external force disappears, the elastic force of spring 3 returns bead 2 to its initial position. This design allows the positioning bead to rotate flexibly and return to its initial position under external force, thereby achieving precise positioning.

[0040] 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.
