[0028] 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.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0031] like Figures 1 to 5 The anti-sway ring 1 shown includes at least two arc-shaped splicing parts 11, specifically as follows: Figure 1 and Figure 2 As shown, the two end faces of the arc-shaped splicing component 11 are provided with snap-fit structures 12, and the center of the arc-shaped splicing component 11 has an arc-shaped groove 13. The snap-fit structure 12 includes mutually adaptable hooks 12a and slots 12b, so that at least two arc-shaped splicing components 11 can be spliced together to form a complete retaining ring structure, and a complete circular hole is formed at the center. It should be noted that the number of arc-shaped splicing components 11 is not limited in the embodiments of this utility model. Those skilled in the art can reasonably set it according to the size. For example, three arc-shaped splicing components 11 can be spliced together to form a complete retaining ring structure, or it can be as follows. Figures 1 to 3The two arc-shaped splicing parts 11 shown are joined together to form a single unit. The hooks 12a and slots 12b in the snap-fit structure 12 are conventional technologies in the art, and those skilled in the art can choose specific structures as needed, which will not be elaborated here.
[0032] In the above embodiment, the snap-fit structure 12 provided on the arc-shaped splicing part 11 enables at least two arc-shaped splicing parts 11 to be spliced together to form a complete retaining ring structure. Compared with the prior art, there is no need to use nuts or process stud threads, thereby reducing costs and improving the ease of installation.
[0033] Optionally, in some embodiments of this utility model, there are two arc-shaped splicing components 11, and the main body of both arc-shaped splicing components 11 is semi-circular. By setting two arc-shaped splicing components 11, the two arc-shaped splicing components 11 can be connected in only one connection, which improves the convenience of operation.
[0034] It should be noted that, in embodiments of this invention, the two arc-shaped splicing parts 11 can be configured as one male and one female, i.e., the hook 12a is disposed on one of the two arc-shaped splicing parts 11, and the slot 12b is disposed on the other. Furthermore, to ensure force balance and ease of processing, in some embodiments of this invention, the following can also be used... Figures 1 to 3 As shown, hooks 12a and slots 12b are respectively disposed on the two end faces of the arc-shaped splice 11. This arrangement ensures that the forces on both ends of each arc-shaped splice 11 are balanced.
[0035] To improve the reliability of preventing swaying, in embodiments of this utility model, such as Figure 3 As shown, the radial outer surface of the arc-shaped splice 11 also has a protrusion 14. The protrusion 14 protrudes radially and at least three are arranged along the circumferential direction. The protrusion 14 is elastic. The arrangement of the three protrusions 14 ensures that all three abut against the external pipe, thereby guaranteeing the coaxiality of the anti-sway ring 1. Furthermore, due to the elasticity of the protrusion 14, it exhibits an interference fit when in contact with the pipe wall, thus preventing wobbling and noise and ensuring coaxiality.
[0036] Furthermore, in embodiments of this utility model, in order to reduce the overall weight of the anti-sway ring 1, such as... Figure 3As shown, the arc-shaped assembly 11 also has a hollowed-out portion arranged along the thickness direction. This hollowed-out portion can have various structural forms, such as an arc-shaped hole. By designing the hollowed-out portion, the overall weight is reduced, and the stacking of components is facilitated. Furthermore, in this embodiment of the invention, the hollowed-out portion is located inside the protrusion 14. By placing the hollowed-out portion inside the protrusion 14, it is easier to shape the protrusion 14; for example, the protrusion 14 can be shaped by applying force from the inside of the hollowed-out portion outwards.
[0037] In some embodiments of this utility model, in order to further improve the reliability of the buckle, such as... Figure 3 As shown, both the hook 12a and the slot 12b are located at the middle position of the end face of the arc-shaped splice 11. This arrangement creates a shoulder structure on the inner side of the slot 12b that abuts against the side wall of the hook 12a, thereby increasing the structural strength of the anti-sway ring 1.
[0038] Optionally, in some embodiments of this utility model, in order to further improve the strength of the buckle, such as... Figure 3 As shown, the base of the hook 12a has a recessed groove 12a1, and the groove 12b has a hook 12b1 that is adapted to the groove 12a1. With this arrangement, when the hook 12a is inserted into the groove 12b, the groove 12a1 and the hook 12b1 simultaneously form a second latch, thereby reducing the risk of the latch disengaging when the two arc-shaped splicing parts 11 are subjected to an external force opposite to the splicing direction.
[0039] Please refer to Figure 4 and Figure 5 In some embodiments of this utility model, an anti-sway structure is also provided, including an inner shaft 2, the aforementioned anti-sway retaining ring 1, and an outer tube 3, specifically as follows: Figure 5 As shown, the tail of the inner shaft 2 has an annular groove 21;
[0040] The anti-sway ring 1 is engaged on the annular groove 21, and the width of the annular groove 21 is adapted to the thickness of the anti-sway ring 1. It should be noted that the width of the annular groove 21 refers to the distance between the two side walls of the annular groove 21 along the axial direction. By setting the annular groove 21 to be adapted to the thickness of the anti-sway ring 1, the anti-sway ring 1 can be prevented from disengaging in the thickness direction, thereby further improving the structural strength of the buckle. In the embodiment of this utility model, the inner diameter of the outer tube 3 is larger than the outer diameter of the inner shaft 2, and the outer periphery of the anti-sway ring 1 abuts against the inner wall of the outer tube 3. In the specific processing and assembly, an annular groove 21 is first machined on the inner shaft 2. Then, the anti-sway ring 1 is snapped into the annular groove 21. Next, the outer tube 3 is sleeved on the outside of the inner shaft 2 and the anti-sway ring 1. By having the outer circumference of the anti-sway ring 1 contact the inner wall of the outer tube 3, the concentricity of the outer tube 3 and the shaft can be ensured, preventing the shaft from swaying in the radial direction. In this embodiment of the utility model, the abutment, i.e., the protrusion 14, is squeezed and deformed by the inner wall of the outer tube 3, which can reduce swaying, avoid noise, and improve the stability and reliability of anti-swaying. It should be noted that the shaft and the outer tube 3 can have various structural forms. For example, the inner shaft 2 can be a lead screw structure, or it can be other application scenarios in this field.
[0041] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
