The utility model discloses a one side that the boss eccentricity of the inner wall extrusion fastening gasket of the circular slot in the fastening nut is big produces radial pressure, and produces a radial pressure rather than the extrusion double-screw bolt that pressure is opposite, and two pressures are to the double-screw bolt and are in opposite directions the cohesion (radial fastening power), increase fastening nut's internal thread and fastening gasket's frictional force to the assurance is more difficult to drop than ordinary nut, and the fastening gasket adopts no internal thread design, easy to assemble and dismantlement.
Description
Technical Field
The utility model relates to a novel self-clinching nut external member belongs to bolt manufacturing technical field.
Background
The nut is the part that couples together mechanical equipment zonulae occludens, and through inboard screw thread, equal specification nut and bolt just can link together, and ordinary nut can only satisfy general equipment, nevertheless under high frequency vibrations equipment and adverse circumstances, has lacked the fastening requirement for a long time the nut lax, and we often need carry out periodic inspection to the structure piece of locking and consolidate, prevents to bring the structure lock dislocation because of the nut loosens. In practice, the tightened nut is fastened by various methods, such as strong glue, electric welding, secondary perforation and reinforcement, but these methods cannot solve the problem of nut loosening and displacement and are troublesome to operate. Stronger, anti-loosening nuts are needed to meet these needs.
SUMMERY OF THE UTILITY MODEL
The problem that exists to the above-mentioned prior art, the utility model provides a novel self-clinching nut external member, one side that the boss eccentric volume that can extrude the fastening gasket through the inner wall of the circular slot in the fastening nut is big produces radial pressure, and produce the radial pressure of an extrusion double-screw bolt opposite rather than pressure, two pressures are to the double-screw bolt and do cohesion (radial fastening power) in opposite directions, increase fastening nut's internal thread and fastening gasket's frictional force, thereby guarantee to be more difficult to drop than ordinary nut, and the fastening gasket adopts no internal thread design, easy to assemble and dismantlement.
In order to realize the purpose, a novel self-tightening nut external member comprises a fastening nut and a fastening gasket, wherein a round platform is arranged on the fastening gasket, an eccentric through hole which runs through the round platform and is the same as the diameter of a bolt hole of the fastening nut is formed in the fastening gasket, a round groove which is concentric with the bolt hole is formed in one end face of the fastening nut, and the diameter of the round groove is larger than the diameter of the upper bottom surface of the round platform and is not larger than the diameter of the lower bottom surface of the round platform.
Preferably, the side surface of the circular truncated cone is a frosted surface or gold-plated emery.
Preferably, the fastening nut is a hexagon nut, six corners of one surface of the fastening nut, which is far away from the circular groove, are provided with reinforcing ribs, and two sidelines of one corner are connected to two ends of each reinforcing rib.
Compared with the prior art, the utility model discloses a one side that the boss eccentricity of the inner wall extrusion fastening gasket of the circular slot in the fastening nut is big produces radial pressure, and produces a radial pressure rather than the extrusion double-screw bolt that pressure is opposite, and two pressures are to the double-screw bolt cohesion in opposite directions (radial fastening power), increase fastening nut's internal thread and fastening gasket's frictional force to the assurance is more difficult to drop than ordinary nut, and the fastening gasket adopts no internal thread design, easy to assemble and dismantlement.

In the figure: 1. the device comprises a fastening nut 1-1, a reinforcing rib 2, a fastening gasket 3 and a bolt.
Detailed Description
The technical solutions in the implementation of the present invention will be clear from the following description and accompanying drawings, and the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 to 5, the embodiment of the utility model provides a novel self-tightening nut external member, including fastening nut 1 and fastening gasket 2, fastening gasket 2 is last to be provided with round platform 2-1, fastening gasket 2 is last to be seted up and to run through round platform 2-1 and the same eccentric through-hole with fastening nut 1's bolt hole diameter, set up the concentric circular slot with the bolt hole on 1 terminal surface of fastening nut, the diameter in circular slot is greater than the last bottom surface diameter of round platform 2-1, is not greater than the lower bottom surface diameter of round platform 2-1.
Preferably, the side surface of the circular truncated cone 2-1 is a frosted surface or gold-plated emery. It is advantageous to increase the frictional force between the fastening nut 1 and the fastening washer 2.
Preferably, the fastening nut 1 is a hexagon nut, six corners of one surface of the fastening nut 1 away from the circular groove are provided with reinforcing ribs 1-1, and two ends of each reinforcing rib 1-1 are connected with two sidelines of one corner. It is advantageous to reinforce the strength of the six corners of the fastening nut 1 when the fastening nut 1 is disassembled using the sleeve.
The working process is as follows: the fastening gasket 2 is sleeved on a screw rod of the bolt 3, one surface of the circular truncated cone 2-1 is far away from the head of the bolt 3, the fastening nut 1 is screwed on the screw rod, and the circular truncated cone 2-1 is inserted into a circular groove of the fastening nut 1, because the circle center of a bolt hole of the circular truncated cone 2-1 is not at the same point as the axial projection of the fastening nut 1, the inner wall of the circular groove can extrude the outer wall of the circular truncated cone 2-1 on the side with large eccentricity inwards to generate radial pressure F1, the fastening nut 1 on the opposite side can generate radial pressure F2, and the friction force between the internal thread of the fastening nut 1 and the external thread of the stud is increased. Thus, a friction force greater than that of a general nut can be achieved.
To sum up, the utility model discloses a one side that the boss eccentric volume of the inner wall extrusion fastening gasket 2 of the circular slot in the fastening nut 1 is big produces radial pressure, and produces a radial pressure rather than the extrusion double-screw bolt of opposite pressure, and two pressures are the double-screw bolt and are held in the same direction (radial fastening power), increase fastening nut 1's internal thread and fastening gasket 2's frictional force to the assurance is more difficult to drop than ordinary nut, and fastening gasket 2 adopts no internal thread design, easy to assemble and dismantlement.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the embodiments may be appropriately combined to form other embodiments understood by those skilled in the art.
