[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0025] Embodiment 1: A rivet fastener with anti-slip threads and easy disassembly, including a fastener housing 1, a baffle 2 and a slide post 4. Slide grooves 3 are provided on both sides inside the fastener housing 1. By providing the slide grooves 3, other components can be cooperated. The lower surface of the baffle 2 is fixedly installed at the top of the fastener housing 1, which is tightly connected to each other. And the outer diameter of the slide post 4 is slidably arranged inside the slide groove 3 opened in the fastener housing 1. The slide groove 3 limits the slide post 4. At the same time, a cavity 5 is provided inside the slide post 4. By providing the cavity 5, it is convenient to arrange other components. A threaded groove is provided in the middle of the top of the slide post 4, which is used to limit other components.

[0026] Embodiment 2: The difference between this embodiment and Embodiment 1 is that limit grooves 10 are provided on both sides of the outer diameter of the slide post 4. By providing the limit grooves 10, other components can be installed. Support rods 11 are slidably arranged inside the two limit grooves 10. The limit grooves 10 limit and support the support rods 11. A mounting screw 6 is threadedly connected inside the threaded groove provided in the middle of the top of the slide post 4, which limits the mounting screw 6 so that it can only move up and down. The top of the mounting screw 6 is fixedly connected to a connecting post 7, which is tightly connected to each other. And the top of the connecting post 7 is fixedly connected to a rotating post 8, which is tightly connected to each other and drives the connecting post 7 through the rotating post 8. The bottom of the mounting screw 6 is fixedly connected to a tapered block 9, which is tightly connected to each other. The outer diameter of the tapered block 9 is slidably connected to one end of the two support rods 11. The tapered block 9 displaces the two support rods 11 outwards. At the same time, the other ends of the two support rods 11 are arranged inside the fastener housing 1. By the outward displacement of the two support rods 11, the fastener housing 1 is propped up to achieve a fastening effect. Silicone coatings 12 are provided on the outsides of the fastener housing 1, the baffle 2 and the slide post 4. Due to the silicone coatings 12, the above components have excellent elasticity and high temperature resistance, and can maintain a good anti-slip effect within a wide temperature range.

[0027] Working principle: In actual use, the fastener housing 1 needs to be installed first. Silicone coatings 12 are provided on the outside of the fastener housing 1 and the outside of other components. Through the silicone coatings 12, the fastener housing 1 has excellent elasticity and high-temperature resistance, and can maintain a good anti-slip effect within a wide temperature range. Chutes 3 are provided on both sides inside the fastener housing 1, and sliding columns 4 slide inside the two chutes 3. A cavity 5 is provided inside the sliding columns 4, and limiting grooves 10 are also provided on both sides of the outer diameter of the sliding columns 4. At the same time, a threaded groove is provided in the middle of the top of the sliding column 4, and a mounting screw 6 is connected inside the threaded groove. The top of the mounting screw 6 is connected to a connecting column 7, and the other end of the connecting column 7 is fixedly installed with a rotating column 8. By rotating the rotating column 8, the connecting column 7 and the mounting screw 6 are driven to rotate threadedly inside the threaded groove provided in the sliding column 4. When the mounting screw 6 rotates, due to the limitation of the threaded groove, the mounting screw 6 achieves the effect of lifting and lowering. When the mounting screw 6 moves downward, it will drive the tapered block 9 to move. Two support rods 11 are slidably connected to the outer diameter of the tapered block 9. When the tapered block 9 moves downward, it will drive the two support rods 11 to move inside the limiting grooves 10, so that the two support rods 11 move outward. Through the relative displacement of the two support rods 11, the fastener housing 1 is expanded outward to achieve the fastening effect. The detachable rivet fastener in this technical solution makes the maintenance work easier and faster. When a component fails, the rivet can be quickly removed for repair or replacement, reducing the maintenance time and cost, so that the fastener has greater flexibility.
