Abstract
A non-loosening screw with an inclined plane and a straight edge; the method is characterized in that: nut 1, inclined bottom surface 11; a bevel pad 2, a straight edge 21; a spring washer 3; screw 4, section 41; the bottom of the nut is provided with an inclined plane, the upper surface of the gasket is provided with an inclined plane, and the edge of the inner circle of the gasket is provided with a straight edge; by providing an axial profile on the flight section of the screw; the spring gasket and the inclined gasket are sleeved into the screw rod, the inclined surface of the gasket faces outwards, the straight edge of the gasket is sleeved against the section of the screw rod, and at the moment, the inclined gasket cannot rotate left and right and only can slide up and down; screwing in the nut, wherein the inclined bottom surface of the nut faces inwards; under the continuous compression action of the spring gasket, the inclined surface of the nut and the inclined surface of the gasket, the straight edge of the gasket and the straight edge of the section of the screw rod interact with each other to tightly combine the nut and the screw rod together; the nut is tightly screwed, and at the moment, the nut cannot rotate left and right or slide up and down, so that the purposes of locking a workpiece and never loosening are achieved.
Description
Technical Field
The utility model relates to the technical field of screw manufacture, in particular to a non-loosening screw with an inclined plane and a straight edge;
background
The screw is a very wide-range fastening part, and the screw is required to be permanently fixed in mechanical equipment, vehicles, rails, equipment rotating at high speed or moving at high speed and the like, but most screw products at present are gradually loosened and loosened under the long-time vibration of the machinery, so that great hidden danger is brought to the operation or traffic of the mechanical equipment and even safety accidents are caused; therefore, the improvement on the prior screw technology is a great subject to be solved in the screw industry.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art, and designs a non-loosening screw with an inclined plane and a straight edge, so that the aim of locking a workpiece and preventing loosening is fulfilled.
A non-loosening screw, the screw comprising:
the bottom of the nut 1 is provided with an inclined bottom surface 11;
the top of the circular gasket is provided with an inclined plane, and the inner circle is provided with a straight edge 21 at one end;
the spring gasket 3 is a C-shaped spring gasket;
the screw 4 has one end fixed with a nut and the other end with a thread section, and one side of the screw is axially cut into a straight section 41.
Further, the nut 1 of the non-loosening screw is provided with normal internal threads, and the bottom of the nut is provided with an inclined bottom surface 11.
Furthermore, in the non-loosening screw, the upper part of the inclined surface gasket 2 is provided with an inclined surface, the inner circle is unthreaded, and one end of the inclined surface gasket is provided with a straight edge 21; the inclined surface of the inclined surface gasket 2 corresponds to the inclined bottom surface of the nut, and the straight edge of the gasket corresponds to the section 41 of the screw 4.
Further, one end of the screw rod of the screw is a fixed nut, the other end of the screw rod is a threaded section, and one side of the threaded section is axially cut into a straight section 41.
The utility model has the advantages of no loosening of the screw, simple parts, strong fastening effect, good universality, simple processing procedure and wide application range, and is suitable for being used in places where no loosening of fastening parts is required.

Detailed Description
The following is a clear and complete description of the technical solution in the embodiment of the present utility model with reference to the accompanying drawings in the embodiment of the present utility model:
referring to fig. 1-6, the specific implementation method is as follows: the screw 4 passes through a workpiece to be fastened, then is sleeved into the spring gasket 3, then the inclined surface gasket 2 is put in, one surface of the inclined surface faces outwards, the straight edge 21 of the inclined surface gasket 2 is aligned with the section 41 of the screw 4, so that the inclined surface gasket 2 cannot rotate left and right and can only slide up and down along the screw 4; screwing the nut 1 again, wherein the inclined bottom surface 11 of the nut faces inwards; then gradually tightening the nut 1, gradually attaching the nut 1 to the inclined surface of the inclined surface gasket 2 under the gradual compression action of the spring gasket 3, continuing until the nut 1 is completely tightened, and completely attaching the nut 1 and the inclined surface gasket 2 to each other at the moment; when the screw is subjected to high-frequency high-pressure vibration by external force and the nut 1 has the outward movement loosening sign, the nut 1 cannot overcome the forces in two different directions of the gong thread of the gong rod and the inclined surface of the inclined surface gasket 2 simultaneously because the nut 1 is limited by the inclined surfaces of the nut 1 and the inclined surface gasket 2, the straight gasket edge 21 and the section 41 of the screw 4, so that the nut cannot be rotated left and right to loosen and cannot move up and down to achieve the effect of no loosening;
the screw has simple parts, can be used as a universal screw, has wide application range, simple whole production process and mechanized batch production, and is worth popularizing and using.
The foregoing description is only of the preferred embodiments of the utility model, and the above-described embodiments are not intended to limit the utility model; various changes and modifications may be made within the scope of the technical idea of the present utility model, and any person skilled in the art may make any modification, modification or equivalent substitution according to the above description, which falls within the scope of the present utility model.
