AI Technical Summary
Existing rivets are time-consuming, labor-intensive, and easily damaged during the connection process, requiring forceful hammering and resulting in low efficiency.
A self-rotating rivet structure was designed, with a cutting helix on the rivet shank and a pressing block and ball bearings above the rivet head. The rivet automatically rotates and screws in by the downward pressure of the pressing block, reducing friction and preventing the pressing block from coming off.
It enables the rivet to be automatically screwed in, saving time and effort, avoiding rivet damage, and improving connection efficiency.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of connecting accessories technology, and specifically relates to a self-rotating rivet structure. Background Technology
[0002] A rivet is a nail-shaped object used to connect two parts (or components) with through holes and a cap at one end. In riveting, the parts are joined by their own deformation or interference fit. Currently, most rivets consist of a rivet shank and a rivet head as a single unit. During connection, force is required to drive the rivet in, which is not only time-consuming and laborious but also easily damages the rivet. Summary of the Invention
[0003] To overcome the shortcomings of the prior art, the present invention provides a spin rivet structure.
[0004] This invention is achieved through the following technical solution: A spin rivet structure includes an integrally connected rivet head and rivet shank, characterized in that: the rivet shank is provided with a cutting helix, a pressing block for pressing down is provided above the rivet head, and a ball bearing is installed below the pressing block.
[0005] The nail tip is integrally connected to the end of the nail rod.
[0006] The pressing block is integrally connected to a ring baffle around its perimeter.
[0007] The beneficial effects of this invention are: by applying a downward pressure to the rivet, the rivet can be automatically rotated, and the rivet can be automatically screwed in while rotating, without the need to use instruments to forcefully hammer the rivet in, saving time and effort, and ensuring that the rivet itself will not be damaged. Attached Figure Description
[0008] The invention will now be further described with reference to the accompanying drawings.
[0009] Appendix Figure 1 This is a schematic diagram of the structure of the present invention; Appendix Figure 2 This is a schematic diagram of the cutting spiral distribution structure of the present invention; In the diagram, 1 is the nail head, 2 is the nail rod, 3 is the cutting auger, 4 is the pressing block, 5 is the ball bearing, 6 is the nail tip, and 7 is the annular baffle. Detailed Implementation
[0010] The attached figure illustrates a specific embodiment of the present invention. This embodiment includes an integrally connected nail head 1 and nail rod 2. The nail rod 2 is provided with a cutting spiral 3, and a pressing block 4 for pressing down is provided above the nail head 1. A ball bearing 5 is installed below the pressing block 4.
[0011] The nail tip 6 is integrally connected to the end of the nail rod 2. The ring baffle 7 is integrally connected to the perimeter of the pressing block 4.
[0012] Using the self-rotating rivet structure of this invention, the rivet tip 6 is aligned with the position of the connector to be driven in, the pressing block 4 is placed above the rivet head 1, and the pressing block 4 is pressed down forcefully. Due to the presence of the cutting spiral 3, the downward pressure is decomposed into the cutting force and rotational force of the rivet shank 2, causing the rivet shank 2 to rotate. While rotating, the rivet shank 2 enters the connector. A ball bearing 5 is provided at the contact point between the pressing block 3 and the rivet head 2 to reduce friction. At the same time, the annular baffle 7 surrounds the rivet head 1 to prevent the pressing block 4 from detaching from the rivet head 1 during pressing, avoiding damage and ensuring efficiency.
