Problems solved by technology

[0002] Nuts are parts that tightly connect mechanical equipment. They can only be connected together through internal threads, nuts and bolts of the same specification. Ordinary nuts can only meet general equipment, but in high-frequency vibration equipment and harsh environments, nuts can be used for a long time. Looseness fails to meet fastening requirements

Embodiment Construction

[0025] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0026] Such as Figure 1-6 As shown, it is a kind of anti-loosening nut assembly of the present embodiment, which includes nut body 1 and gasket 2 arranged up and down in sequence, the outer movable sleeve of gasket 2 is provided with anti-loosening ring sleeve 3, and the bottom surface of nut body 1 is arranged There are protrusion one 11 and protrusion two 12, both of protrusion one 11 and protrusion two 12 are in the shape of a right triangle, and the right angle sides of protrusion one 11 and protrusion two 12 are all fixedly arranged on the bottom surface of the nut body 1 , the other right-angled sides of the first protrusion 11 and the second protrusion 12 are perpendicular to the bottom surface of the nut body 1, the hypotenuses of the first protrusion 11 and the second protrusion 12 have the same direction, the gasket 2 is a ring-shaped structu...

Abstract

The invention provides a lock nut assembly, and relates to the technical field of fasteners. The lock nut assembly comprises a nut body and a gasket which are sequentially arranged in the vertical direction; the gasket is movably sleeved with a lock loop; the bottom surface of the nut body is provided with a first protrusion and a second protrusion, the first protrusion and the second protrusion are each in a right triangle shape, one of right-angle sides of the first protrusion and one of right-angle sides of the second protrusion are both fixedly arranged on the bottom surface of the nut body, the other right-angle side of the first protrusion and the other right-angle side of the second protrusion are both perpendicular to the bottom surface of the nut body, and bevel edges of the firstprotrusion and the second protrusion are the same in orientation; the gasket is of an annular structure, and the top surface of the gasket is provided with a first groove and a second groove; one endof the first groove communicates with the inner circle of the gasket, one end of the second groove is flush with the outer circle wall of the gasket, and the first protrusion and the second protrusion correspond to the first groove and the second groove in position in the vertical direction. The lock nut assembly has the advantages that after tightening, the connection tightness is improved by increasing friction force, and loosening of the nut body can be prevented.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a locknut assembly. Background technique [0002] Nuts are parts that tightly connect mechanical equipment. They can only be connected together through internal threads, nuts and bolts of the same specification. Ordinary nuts can only meet general equipment, but in high-frequency vibration equipment and harsh environments, nuts can be used for a long time. Looseness does not meet the fastening requirements. Therefore, anti-loosening must be carried out, otherwise it will affect normal work and cause accidents, so nuts with stronger fastening and anti-loosening are required to meet these requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a locknut assembly which can improve the fastness of the connection by increasing the friction force after tightening and can prevent the nut body from loosening. [000...
