Abstract
The utility model relates to a locknut comprises upper nut and lower nut two parts, and coaxial screw through-hole has all been made in upper nut and the lower nut, and upper nut is a whole with the coaxial spacing equipment of lower nut. The utility model discloses replace existing nut, bullet pad, flat pad, made things convenient for assembly work, eliminated the processing and played the material of pad, flat pad and the waste of process, it is more obvious reliable to step up locking stopping effect simultaneously, can use in the field of the similar action moreover, extensive applicability.
Description
Technical Field
The utility model belongs to assembly accessories field, especially a locknut.
Background
At present, in the assembly production process, the common nut assembly that the panel beating assembly generally used and the cooperation of bullet pad play locking effect, but in reality, only lean on the bullet pad can't really play locking effect.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide a small and exquisite compactness of structure, convenient operation, reliable durable locknut, effectively get rid of the easy not hard up drawback in the current screw nut assembly back use.
The utility model provides a its technical problem take following technical scheme to realize:
a locknut is characterized in that: the nut is composed of an upper nut and a lower nut, coaxial threaded through holes are formed in the upper nut and the lower nut, and the upper nut and the lower nut are assembled into a whole in a coaxial limiting mode.
And the upper nut comprises an outer hexagonal cover body, a cylinder and an annular groove, the outer hexagonal cover body is of a regular hexagonal prism structure, the cylinder is coaxially arranged at one axial end of the outer hexagonal cover body, and the annular groove is arranged on the periphery of the cylinder at the connecting position of the cylinder and the outer hexagonal cover body.
The lower nut comprises an outer hexagonal main body, a cylindrical cavity and a sub-opening, wherein the cylindrical cavity is formed in one end of the outer hexagonal main body, and the sub-opening formed by an annular necking is formed in a port of the cylindrical cavity; the inner diameter of the cylindrical cavity is the same as the outer diameter of the cylinder, and the size of the sub-opening is matched with the annular groove.
And the outer hexagonal cover body of the upper nut and the outer hexagonal main body of the lower nut have the same outer diameter size.
The utility model has the advantages that:
the utility model discloses replace existing nut, bullet pad, flat pad, made things convenient for assembly work, eliminated the processing and played the material of pad, flat pad and the waste of process, it is more obvious reliable to step up locking stopping effect simultaneously, can use in the field of the similar action moreover, extensive applicability.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
A locknut consists of an upper nut and a lower nut, wherein coaxial threaded through holes 3 are formed in the upper nut and the lower nut, and the upper nut and the lower nut are coaxially limited and assembled into a whole;
the specific structures of the two parts are respectively as follows:
the upper nut comprises an outer hexagonal cover body 1, a cylinder 7 and an annular groove 6, the outer hexagonal cover body is of a regular hexagonal prism structure, the cylinder is coaxially arranged at one axial end of the outer hexagonal cover body, and the annular groove is arranged on the periphery of the cylinder at the connecting position of the cylinder and the outer hexagonal cover body;
the lower nut comprises an outer hexagonal main body 2, a cylindrical cavity 5 and a sub-opening 4, wherein a cylindrical cavity is formed in one end of the outer hexagonal main body, and a sub-opening formed by an annular necking is formed in a port of the cylindrical cavity; the inner diameter of the cylindrical cavity is the same as the outer diameter of the cylinder, and the size of the sub-opening is matched with the annular groove.
The outer hexagonal cover body of the upper nut is the same as the outer hexagonal main body of the lower nut in size, and the same wrench can be used for operation.
When the nut assembly is used, the lower nut is assembled downwards, the wrench is used for clockwise rotating the outer hexagon of the integral nut to the plane of the assembly body, and the nut assembly is screwed tightly; and then the spanner is used for screwing the outer hexagonal part of the nut in a counter-clockwise reverse direction, and at the moment, because the distance is generated between the upper nut and the lower nut, the threads of the upper nut and the lower nut are respectively attached to the upper surface and the lower surface of the thread of the screw, and the thread of the screw is clamped, so that the backstopping effect is achieved.
Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims, and therefore, the scope of the present invention is not limited to the disclosure of the embodiments and the accompanying drawings.
