Description

Technical Field

[0001] This utility model relates to a zinc alloy screw anti-floating lock mechanism. Background Technology

[0002] Screws are a common type of fastener, widely used in machinery, electrical appliances, and buildings. Most screws are made of metal, are cylindrical, and have grooves on their surface called threads. A thread is a helical, inclined surface that wraps around the side of the screw.

[0003] However, existing screw-locking mechanisms cannot accurately detect screws after locking. For example, if a screw is loose, it can easily fall out during later use. Therefore, a zinc alloy screw anti-loosening mechanism needs to be designed to solve the above problems. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a zinc alloy screw anti-floating lock mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a zinc alloy screw anti-floating lock mechanism, including a zinc alloy screw and a connecting base;

[0006] The connecting base is provided with a threaded hole, and the inner wall of the threaded hole is symmetrically provided with two axial sliding grooves, and the inner wall of the threaded hole is provided with two positioning grooves that correspond one-to-one with the axial sliding grooves.

[0007] The zinc alloy screw includes a screw rod and a head. The screw rod is threadedly connected to a threaded hole. A circumferential mounting groove is provided on the outer wall of the end of the screw rod near the head. Two positioning spring pieces corresponding to positioning grooves are engaged in the circumferential mounting groove. One end of each of the two positioning spring pieces extends to the outside of the circumferential mounting groove and engages with the corresponding positioning groove.

[0008] Preferably, the positioning spring is a metal spring.

[0009] Preferably, a gasket is provided between the head and the connecting base.

[0010] Preferably, the gasket is a zinc alloy gasket.

[0011] Preferably, the head has a polygonal structure.

[0012] The advantages and beneficial effects of this utility model are as follows: It provides a zinc alloy screw anti-floating lock mechanism with a reasonable structure, which can help the operator judge whether the screw is properly locked, prevent floating lock, and avoid the problem of screw falling off during later use.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] The specific technical solution of this utility model is as follows:

[0018] like Figure 1 and Figure 2 As shown, a zinc alloy screw anti-floating lock mechanism includes a zinc alloy screw and a connecting base 10;

[0019] The connecting base 10 is provided with a threaded hole 11. The inner wall of the threaded hole 11 is symmetrically provided with two axial sliding grooves 12, and the inner wall of the threaded hole 11 is provided with two positioning grooves 13 that correspond to and communicate with the axial sliding grooves 12.

[0020] The zinc alloy screw includes a screw 21 and a head 22. The screw 21 is threadedly connected to a threaded hole 11. A circumferential mounting groove 23 is provided on the outer wall of the end of the screw 21 near the head 22. Two positioning springs 40 corresponding to positioning grooves 13 are engaged in the circumferential mounting groove 23. One end of each of the two positioning springs 40 extends to the outside of the circumferential mounting groove 23 and engages with the corresponding positioning groove 13.

[0021] Furthermore, the positioning spring 40 is a metal spring.

[0022] Furthermore, a gasket 50 is provided between the head 22 and the connecting base 10.

[0023] Furthermore, the gasket 50 is a zinc alloy gasket.

[0024] Furthermore, the head 22 has a polygonal structure.

[0025] The working principle of this utility model of a zinc alloy screw anti-floating lock mechanism is as follows: two positioning springs 40 are pre-installed into the circumferential mounting grooves 23 respectively; when the screw 21 is screwed to the set depth of the threaded hole 11, the ends of the two positioning springs 40 located outside the circumferential mounting grooves 23 are aligned with the two axial sliding grooves 12 respectively. As the screw 21 continues to screw into the threaded hole 11, the ends of the positioning springs 40 located outside the circumferential mounting grooves 23 will move into the axial sliding grooves 12 and move along the axial sliding grooves 12. At the same time, the groove wall of the axial sliding grooves 12 will squeeze and deform the positioning springs 40. When the ends of the positioning springs 40 located outside the circumferential mounting grooves 23 move to the position corresponding to the positioning grooves 13, the ends of the positioning springs 40 located outside the circumferential mounting grooves 23 will expand outward and spring into the positioning grooves 13. At this time, the positioning springs 40 will make a "click" sound to help the operator judge that the screw is locked in place.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
