Description

Rivet

This creation provides a pull stud, especially a tapered abutment surface extending on the side of the head of the pull rod. When the pull rod is pulled down, the inner wall surface of the perforation of the tube body will expand outward along the holding surface. By dispersing the force of impact, thereby avoiding the fracture of the head, and when the head is displaced inside the perforation, the inner wall surface of the perforation can be guided apart by the resisting surface to prevent the head from breaking inside the perforation.

At present, there are many ways to join and fix the board to the board. The common ones are: welding, bonding, screw locking or nail fixing. Among them, the nail is to fill the nail into the nail gun. When riveting the two plates, the two plates can be shot through the nail gun first, and then the rod body of the pull nail can be pulled out, so that the sleeve body of the pull nail can be deformed and riveted to the two plates. Objects, by which the two plates are firmly integrated into one.

However, the commonly used pull stud structure includes a pull rod and a sleeve body, and the pull rod has a T-shaped head, and a rod body is extended at one end of the head, and the sleeve body has a hollow tube body, and then An end of the tube body extends outwardly with a ring-shaped blocking body, and the rod body of the rod can pass through the inside of the tube body, and the head of the rod is pressed against the upper edge to complete the assembly, and the assembly can be pulled after assembly The nail is loaded in the nail gun, and when the nail gun is used on the two plates, the T-shaped head of the lever will first pass the two plates and then pull the lever back through the nail gun to make The head of the rod is squeezed into the tube body of the sleeve body, so that the upper edge of the tube body is expanded outward and riveted on the plate, and then the rod can be pulled. After pulling out of the sleeve body, the two plate-shaped objects can be riveted together by the sleeve body.

However, in the aforementioned riveting process, since the head of the drawbar is T-shaped, the head and the upper edge of the sleeve body are parallel to each other, so that the head is pulled back and hits the upper edge of the pipe body At this time, the head is likely to be directly broken due to the excessive force of the impact, so that the upper edge of the tube body cannot be effectively deformed, so that the sleeve body cannot reliably rive the two plates together, and the T The head of the type is also easy to break and remain inside the tube body, so that the head will roll inside the tube body, resulting in the loose state of the two plate-like joints, which may affect the performance or quality of the sleeve body.

Therefore, how to solve the above-mentioned lack of inconvenience and inconvenience is the direction of improvement for those engaged in this industry.

Therefore, in view of the above-mentioned deficiencies, the creators collected relevant materials and, after evaluation and consideration from various parties, began to design new patents for such pull studs.

The main purpose of this creation is that the sleeve is a pipe body for passing through the first hole of the first plate and the second hole of the second plate, and a perforation is formed longitudinally inside the pipe body, and one end of the pipe body A stop body for stopping on the second plate material is extended outward, and then the head of the rod is pressed against the upper edge of the tube body, and the head side is tapered downward to extend with a resisting surface and resisting A rod body for penetrating into the perforation is extended under the surface. When the rod body of the pull rod is pulled down, the inner wall surface of the perforation of the pipe body will be spread outward along the guide of the inclined resisting surface to disperse The force applied by the impact on the upper edge of the tube body to prevent the head from breaking directly, and when the head is displaced inside the perforation of the tube body, the inner wall surface of the perforation can also be guided apart by the resisting surface, thereby preventing the head The purpose is to break the part and leave it inside the perforation.

The secondary purpose of this creation is that when the tube body of the casing is stretched out, the limiting body protruding from the surface of the tube body is pressed on the surface of the first plate, because the limiting body is convex Therefore, the tube body can reduce the amount of outward expansion, thereby reducing the difference between the outer diameter of the head of the tie rod and the hole diameter of the perforation of the tube body, thereby achieving the purpose of reducing the occurrence of head fracture.
