Technical Field
[0001] The utility model relates to the technical field of sheet metal fasteners, in particular to a sheet metal fastener. Background Art
[0002] Sheet metal fasteners are divided into three categories: right-angle fasteners, butt fasteners, and rotary fasteners. Sheet metal fasteners are a type of connector that is widely used in many fields, especially in machinery manufacturing, automotive industry, aerospace, construction engineering, and electronic product manufacturing. It is mainly used to connect and fix various components, provide reliable connections, and ensure the stability and durability of the structure.
[0003] However, the rotating fastener cannot fix itself after connecting various components at a deflection angle. Since the rotating fastener is not fixed after the components are connected, the connected components are easily disconnected from the rotating fastener when shaking occurs, thereby reducing the connection effect of the rotating fastener.

The bottom inner wall of the circular slot is rotatably connected with a swing circular block. The surface of the swing circular block is provided with a power-assisting arc tooth at a position close to the locking tooth plate. The surface of the swing circular block is movably hinged with a fastener body at a position away from the cube connecting block. Through the cooperation of the swing circular block and other structures, the fastener body can swing back and forth in the horizontal plane.
[0007] As an improvement of the above technical solution, the anti-rotation structure includes a movable ring, a vertical slot, a vertical block and a fixed tooth plate. The movable ring is movably sleeved on the periphery of the rotating screw, the vertical slot is opened on the periphery of the rotating screw, the vertical block is fixedly connected to the inner ring surface of the movable ring, the vertical slot is movably engaged with the vertical block, and the fixed tooth plate is arranged on the rear inner wall of the square connecting block. The rotating screw is fixed by the anti-rotation structure to prevent the rotating screw from rotating, thereby causing the locking tooth plate to disengage from the engagement with the assisting arc tooth.
[0008] As an improvement of the above technical solution, both left and right ends of the cube connecting block are designed in arc shape, which increases the swing angle of the fastener body.
[0009] As an improvement of the above technical solution, an anti-slip ring tooth is provided on the surface of the movable ring near the bottom, and the anti-slip ring tooth moves downward to engage with the fixed tooth plate to fix the rotating screw.
[0010] The beneficial effects of the utility model are as follows: after the fastener body is fixed to the component, the locking tooth plate moves and engages with the assisting arc tooth, and the fastener body is fixed by the assisting arc tooth. At the same time, the anti-slip ring tooth moves downward and engages with the fixed tooth plate to fix the rotating screw, preventing the rotating screw from rotating, thereby preventing the locking tooth plate from disengaging from the assisting arc tooth, increasing the stability of the two fastener bodies after connecting the components, preventing the components from being separated from the fastener body during shaking, and thus improving the connection effect of the fastener body.

[0018] The fastener fixing structure includes a moving block 22, a pushing connecting plate 23 and a locking tooth plate 24. The inner ring of the moving block 22 is connected to the outer periphery of the rotating screw 21 by a thread. The pushing connecting plate 23 is movably hinged on the left side of the moving block 22. The locking tooth plate 24 is movably clamped on the inner side of the placement slot 2.
