Problems solved by technology

The traditional fasteners (nuts, bolts, washers) currently used rely on the fastening effect of mechanical fastening or structural fastening of the connection combination between fasteners due to their own structural limitations. It cannot resist long-term high temperature and high pressure. , The loosening and deformation of the connection between the fasteners in the environment of high-frequency vibration and shock make the fastening failure, which has become a major cause of serious harm and even accidents, and it is a major problem that has not yet been broken through in today's industry. , is a major scientific research topic to be solved urgently

[0022] Integral anti-loosening fastening nut and washer of type 1A movable connection

[0023] The feature of the assembly is that each wedge surface on the concave-convex bottom surface of the nut is inclined from front to back along the horizontal counterclockwise direction with the same inclination angle with the horizontal plane.

[0024] The integrated anti-loosening fastening nut and washer of type A movable connection is composed of nut 1 and washer 2; the nut 1 is a hexagonal nut, the top surface is a plane regular hexagon, the center is a screw hole, and the inner wall has a thread 5, and its The six sides 1-1 have the same shape and size, and rotate 90° in the vertical plane to form a right-angled trapezoidal sidewall surface. Its bottom surface 4 has a small section of thin-walled straight cylinder 3 protruding from the hollow lower screw mouth. The internal thread on the body is connected and matched with the internal thread 5 on the nut cavity, and the nut bottom ...

[0028] Integral anti-loosening fastening nut and washer for example 2B type movable connection

[0029] The feature of the assembly is that each wedge surface on the concave-convex bottom surface of the nut and the horizontal plane are inclined from rear to front along the horizontal counterclockwise direction at the same inclination angle.

[0030] The integrated anti-loosening fastening nut and washer of B-type movable connection is composed of nut 1 and washer 2; the nut 1 is a hexagonal nut, the top surface is a plane regular hexagon, the center is a screw hole, and the inner wall has a thread 5. The six sides 1-1 have the same shape and size, and rotate 90° in the vertical plane to form a right-angled trapezoidal sidewall surface. Its bottom surface 4 has a small section of thin-walled straight cylinder 3 stretching out from the hollow screw opening. This straight cylinder 3 The internal thread on the cavity is connected and matched with the internal thread 5 on the cavit...

Abstract

The invention discloses integral anti-loosening fastening nut and gasket in movable connection, wherein a straight column is arranged in the center of the bottom of the hexagonal nut, the section of intracavity thread of the straight column, extending from a lower screw port, is connected with the inner thread of the nut, the bottom of the nut at the outer side of the straight column is provided with six wedge tooth-shaped concave-convex surfaces formed by six wedge surfaces with same shapes and sizes, and the six wedge surfaces are downwards inclined in each vertical surface along the same horizontal rotation direction; the bottom of the gasket is a circular-ring slice, the back face of the gasket is provided with anti-slip sharp strips with bulged ridge tops, the centers of the anti-slip sharp strips are symmetrically arranged, a regular hexagonal prism with a through hole in the center is arranged on the circular-ring slice, and the top surface of the gasket is a wedge tooth-shapedconcave-convex surface which is formed by six wedge surfaces and are adaptive to the bottom of the nut; and the straight column is sheathed in the central through hole of the gasket, and the integrally movable connection of the nut and the gasket is realized through matching the tapered inclined inner wall of the hole with the extended lower port of the straight column. The invention has the advantage of effectively preventing connecting members from loosening under the impact environment with high temperature, high pressure, high frequency and strong vibration, and damaged assemblies can be replaced by using common tools.

Description

technical field [0001] The invention relates to a fastener, in particular to a nut and a washer, in particular to a washer with an anti-loosening fastening nut and its matching integrated movable connection. Background technique [0002] The nut and the washer are combined with the screw, which is a very widely used structural connection. The traditional fasteners (nuts, bolts, washers) currently used rely on the fastening effect of mechanical fastening or structural fastening of the connection combination between fasteners due to their own structural limitations. It cannot resist long-term high temperature and high pressure. , The loosening and deformation of the connection between the fasteners in the environment of high-frequency vibration and impact, etc., which make the fastening failure, become a major cause of serious harm and even accidents, and it is a major problem that has not yet been broken through in today's industry. , is a major scientific research topic to ...
