Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and more specifically, to a quick-thread screw. Background Technology

[0002] Quick-release screws, also known as self-tapping screws, have a self-tapping tip that allows them to penetrate materials with slightly lower hardness. However, when inserting the screw, it's difficult to maintain perpendicularity to the surface being penetrated during the hand-held operation, easily leading to misalignment during screwing, resulting in uneven installation and poor overall performance. Therefore, this invention proposes a quick-release screw. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a quick thread screw, which has the characteristics of being able to be positioned and being screwed flat.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: This utility model relates to a quick-release screw, comprising a self-tapping screw body, one end of which has a rotating part and the other end has a self-tapping part. An anti-deviation claw ring, which moves axially relative to the self-tapping screw body, is fitted onto the self-tapping screw body. The anti-deviation claw ring includes an inner ring plate, with a central positioning hole in the center for the self-tapping screw body to pass through. An upper retaining ring extending upwards axially and a lower retaining ring extending downwards axially are fixedly connected to the outer side of the inner ring plate. The bottom of the lower retaining ring is circumferentially covered with sharp teeth. Several spring pieces protruding from the upper end face are circumferentially distributed on the inner ring plate. The height of the spring pieces is not greater than the height of the upper retaining ring, and the inner diameter of the upper retaining ring is greater than the outer diameter of the rotating part.

[0005] The present invention is further configured such that: the upper retaining ring and the lower retaining ring are an integral structure; the upper retaining ring and the inner ring plate are an integral structure.

[0006] The present invention is further configured such that the spring sheet and the inner ring sheet are an integral structure.

[0007] The present invention is further configured such that the included angle between two adjacent sharp teeth is equal.

[0008] The present invention is further configured such that the included angle between two adjacent spring pieces is equal.

[0009] The present invention is further configured such that the height of the spring piece is less than the height of the upper retaining ring.

[0010] In summary, this utility model has the following beneficial effects: The quick-release screw involved in this utility model first finds the screwing position, then presses and pre-connects the anti-deviation claw ring to the surface to be penetrated, so that the inner ring is separated from the surface to be penetrated. Then, the self-tapping screw body is taken out, its front end is inserted into the central positioning hole, and then screwed into the surface to be penetrated. The rotating part is embedded in the upper retaining ring and pressed tightly on the circumferential spring sheet. Finally, it is screwed down further until the sharp teeth on the anti-deviation claw ring also penetrate into the surface to be penetrated and the inner ring is tightly attached to the surface to be penetrated. During this process, it can prevent the self-tapping screw body from axially deviating, can be positioned, screwed flat, has complete overall function, and is highly practical.

[0012] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0013] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0014] Example 1 See Figure 1 and Figure 2 As shown, the quick-release screw involved in this embodiment includes a self-tapping screw body 1. One end of the self-tapping screw body 1 has a rotating part 2 and the other end has a self-tapping part 3. The self-tapping screw body 1 is fitted with an anti-deviation claw ring 100 that moves axially relative to each other. The anti-deviation claw ring 100 includes an inner ring plate 4. A central positioning hole 5 is opened in the center of the inner ring plate 4 for the self-tapping screw body to pass through. An upper retaining ring 6 extending upward along the axial direction and a lower retaining ring 7 extending downward along the axial direction are fixedly connected to the inner ring plate 4. The bottom of the lower retaining ring 7 is surrounded by sharp teeth 8. The inner ring plate 4 is surrounded by a number of spring pieces 9 protruding from the upper end face. The height of the spring pieces 9 is not greater than the height of the upper retaining ring 6. The inner diameter of the upper retaining ring 6 is greater than the outer diameter of the rotating part 2.

[0015] Furthermore, the upper retaining ring 6 and the lower retaining ring 7 are integral structures; the upper retaining ring 6 and the inner ring plate 4 are integral structures.

[0016] Furthermore, the spring piece 9 and the inner ring piece 4 are an integral structure.

[0017] Furthermore, the included angle between two adjacent sharp teeth 8 is equal.

[0018] Furthermore, the included angle between two adjacent spring pieces 9 is equal.

[0019] Furthermore, the height of the spring piece 9 is less than the height of the upper retaining ring 6.

[0020] In this implementation scheme, the anti-deviation claw ring 100 is first used to locate the installation position of the self-tapping screw body 1, so that the target point is located in the center positioning hole 5. Then, the lower retaining ring 7 faces the installation surface, and the upper retaining ring 6 is manually pressed until the tip of the sharp tooth 8 on the anti-deviation claw ring 100 penetrates into the installation surface (not completely penetrated, the inner ring plate 4 is suspended). Then, the self-tapping screw body 1 is taken out and inserted into the center positioning hole 5 for screwing. While ensuring that the screwing point does not deviate, the inner ring plate 4 provides lateral positioning, so that the self-tapping screw body 1 remains perpendicular to the installation surface. The screwing point 2 is pressed against the upper end of the inner ring plate 4, and the spring piece 9 is deformed. Finally, the screwing is continued to be turned downwards, so that the sharp tooth 8 on the anti-deviation claw ring 100 penetrates further until it is completely penetrated. At this time, the inner ring plate 4 is pressed against the installation surface.

[0021] The quick-release screw of this utility model first locates the screwing position, then presses and pre-connects the anti-deviation claw ring to the surface to be penetrated, so that the inner ring is separated from the surface to be penetrated. Then, the self-tapping screw body is taken out, its front end is inserted into the central positioning hole, and then screwed into the surface to be penetrated. The rotating part is embedded in the upper retaining ring and pressed tightly on the circumferential spring. Finally, it is screwed down further until the sharp teeth on the anti-deviation claw ring also penetrate into the surface to be penetrated and the inner ring is tightly attached to the surface to be penetrated. During this process, it can prevent the self-tapping screw body from axially deviating, can be positioned, and is screwed flat. The overall function is perfect and the practicality is strong.
