Description
Technical Field
The invention relates to a bolt, in particular to a locking bolt.
Background
A circle of sawteeth is arranged in the existing bolt, and the purpose is to play a role in preventing looseness. However, it is relatively difficult to provide the saw teeth on some bolts with smaller diameters, and particularly, it is more difficult to provide the saw teeth on the bolts with smaller diameters, and the effect after the arrangement is not ideal.
Disclosure of Invention
A bolt fastener with fan-shaped saw teeth is provided, and a locking saw tooth structure can be used on a bolt with a small diameter through the saw teeth of the fan-shaped surface.
To achieve the above object, the present invention provides a bolt fastener having scallops, comprising: the novel gear box is composed of a bolt, a cap-shaped nut, fan-shaped sawteeth, a stop column and a spring, wherein the fan-shaped sawteeth are a combination of sawteeth in a fan shape selected from any part of a circle of annular ring sawteeth; the circular points of the sawteeth in the sector shape point to one side of the edge of the screw rod, and the sawteeth in the sector sawteeth are different in length and are distributed according to a certain angle; one end of the bolt screw is provided with a head, and the surface of the head of the other end of the bolt screw is provided with first fan-shaped sawteeth 31; the surface of the stop column is provided with second fan-shaped sawteeth 32, and the distribution directions of the first fan-shaped sawteeth 31 and the second fan-shaped sawteeth 32 are opposite; the stop column is positioned in the cap-shaped nut, and the cap nut cover body and the stop column are of polygonal structures; the surface of the stop column is provided with the second fan-shaped sawteeth 32, the bottom surface is a plane, and the spring is arranged between the bottom surface of the stop column and the inner surface of the cover-shaped nut cover body.
Further, the fan-shaped serrations are used on the surface of the screw tip of the bolt having a smaller diameter.
Furthermore, each sawtooth in the fan-shaped sawtooth is different in length, and the distribution interval rule is the same, and has certain height.
In the embodiment of the invention: the sawteeth are designed into a sector shape, so that the sawteeth are also provided with anti-loosening sawteeth on the small-diameter screw, and the height of the sawteeth meets the anti-loosening requirement. Thus, the anti-loose sawtooth structure can be applied to more types of bolts.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 4, a bolt fastener having scallops, comprising: the bolt is composed of a bolt 1, a cap-shaped nut 2, fan-shaped sawteeth 3, a stop column 21 and a spring 22, wherein the fan-shaped sawteeth 3 are a saw tooth combination in a fan shape selected from any part of a circle of annular ring sawteeth; the circular points of the sawteeth in the sector shape point to one side of the edge of the screw rod, and the sawteeth in the sector sawteeth 3 are different in length and are distributed according to a certain angle; one end of a screw rod of the bolt 1 is provided with a head part, and the surface of the head part of the screw rod at the other end is provided with first fan-shaped sawteeth 31; the surface of the stop column 21 is provided with second fan-shaped saw teeth 32, and the distribution directions of the first fan-shaped saw teeth 31 and the second fan-shaped saw teeth 32 are opposite; the stop column 21 is positioned in the cap nut 2, and the cap nut 2 and the stop column 21 are both polygonal; the surface of the stop column 21 is provided with the second fan-shaped sawteeth 32, the bottom surface is a plane, and the spring 22 is arranged between the bottom surface of the stop column 21 and the inner surface of the cover body of the cover-shaped nut 2.
Specifically, the saw teeth are arranged in a circle of ring shape, the inner diameter side of the ring is used as a dot, the saw teeth are spread towards the outer edge of the ring to form a plane with a sector structure, the saw teeth distributed on the surface of the sector have different lengths, but the arrangement and distribution modes are the same, and the sector saw teeth 3 are formed. The first fan-shaped saw teeth 31 are distributed on the surface of the screw head of the bolt 1, and the circular points and the outer side edges of the fan-shaped saw teeth 3 are correspondingly distributed on the edge of the surface of the head.
The second fan-shaped saw teeth 32 are distributed on the surface of the stop column 21, and the first fan-shaped saw teeth 31 and the second fan-shaped saw teeth 32 are distributed in opposite directions, rotate clockwise and are mutually clamped anticlockwise. The cross section of the sawteeth of the fan-shaped sawteeth 3 is a right-angled triangle, the end of the screw is overlooked, and the right-angled edges are clockwise distributed opposite to the bevel edge.
The stop column 21 is located in the cover body of the cover-shaped nut 2, a polygonal concave hole is formed in the cover body, and the stop column 21 is also a polygonal cylinder. The stop post 21 can only move up and down in the cover body and cannot rotate. Meanwhile, the spring 22 is arranged between the bottom surface of the stop column 21 and the inner surface of the cover body, and the spring 22 provides elasticity and support for the stop column 21, so that the first fan-shaped saw teeth 31 on the surface of the screw head and the second fan-shaped saw teeth 32 on the surface of the stop column 21 can be tightly connected and buckled with each other.
