Abstract
The utility model discloses a kind of locking fastening assemblies, including nut, lock washer, stop nut, bolt.The inner circle side of the lock washer is equipped with rectangular teeth, outer circle edge is axially arranged with boss, it is distributed uniformly and circumferentially in the bottom surface of boss with teeth, the stop nut top surface is inwardly provided with a ring annular groove, the bottom surface of annular groove is distributed uniformly and circumferentially with teeth, and the bolt is provided with slot along axial direction.In use, by lock washer and bolt-connection and cooperation and stop nut, then be bolted on bolt with nut and compress lock washer, so that realizing prevents bolt and nut component from loosening.The utility model is simple in construction, easy to disassemble and assemble, is able to satisfy use demand, and reaches good using effect.
Description
Technical field:
The utility model relates to technical field of fastening, and in particular to a kind of locking fastening assembly.
Background technique:
Bolt and nut couples one of common fastener as machinery field equipment, have dismounting is simple, have a wide range of application,
The features such as at low cost, but general bolt and nut is in use, will lead to the loosening of bolt and nut due to vibration etc.
And then fall off, this will result in huge security risk, it is seen that produce the good bolt and nut group of a kind of reliable operation, anti-loosing effect
Part is just particularly important.Currently, usually adding between nut and fastening object when existing conventional bolt nut assembly cooperates
Have traditional spring washer, installation and removal are easy, but it is locking, anticreep ability is general.
Utility model content:
The technical problem to be solved by the utility model is to provide a kind of locking fastening assemblies, are able to solve in the prior art
The disadvantage that conventional bolt nut assembly is locking when encountering the environment such as vibration, load, anticreep is poor.
To achieve the above object, the utility model is implemented with the following technical solutions: the utility model is that one kind prevents elastic
Gu component, including nut, lock washer, stop nut, bolt；Lock washer inner circle side is equipped with rectangular teeth, outer circle edge
It is axially arranged with boss, is distributed uniformly and circumferentially in the bottom surface of boss with teeth；The top surface of the stop nut is inwardly provided with one
Ring annular groove, the bottom surface of annular groove are distributed uniformly and circumferentially with teeth；The bolt is provided with slot along axial direction.
When fastening to fastening object, bolt is passed through to the unthreaded hole of fastening object, stop nut is bolted on bolt
And compress fastening object, the rectangular teeth of lock washer is fallen into the slot of bolt, the equally distributed tooth in lock washer boss bottom surface with
The equally distributed tooth engagement in stop nut annular groove bottom surface together, then by nut is bolted on bolt, is continuously applied to tighten
Torque makes nut compress lock washer.
In practical application, the requirement due to different fasteners for nut screw-down torque is different, stop nut annular groove
Tooth and the tooth of lock washer boss bottom surface may not be able to be at a fully engaged, that is, partially engaged state is in, at this time due to the two tooth
Isosceles triangular structure determine remain to stop stop nut loosening, and nut compress lock washer, further hinder locking
The loosening of nut.
After adopting the above scheme, lock washer, loose nut and bolt are secured together, and nut compresses lock washer, makes it
Between mutually constrain to realize bolt and nut component to fastening object fastening.
The beneficial effects of the utility model are: the 1, Each part of locking fastening assembly is simple, it can be raw by specification batch
It produces；2, easy to operate, assembly is simple with dismounting；3, the higher vibration of intensity can be resisted, has the advantages that locking, anticreep.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.

Specific embodiment
A kind of check bolt nut assembly as shown in Figs 1-4, including nut (1), lock washer (2), stop nut (3),
Bolt (4)；It is characterized by: the inner circle side of lock washer (2) is equipped with rectangular teeth (2-1), outer circle edge is axially arranged with boss (2-
2) it, is distributed uniformly and circumferentially (2-3) with teeth in the bottom surface of boss (2-2), the top surface of stop nut (3) is inwardly provided with a circle
Annular groove (3-1), the bottom surface of annular groove (3-1) are distributed uniformly and circumferentially (3-2) with teeth, and bolt (4) is opened along axial direction
There is slot (4-1).
Bolt (4): being passed through the unthreaded hole of fastening object by the assembly method of the utility model, and stop nut (3) is bolted in spiral shell
On bolt (4) and fastening object is compressed, the rectangular teeth (2-1) of loose washer (2) inner circle side is fallen into the slot (4-1) of bolt (4), is prevented
The boss (2-2) of loose washer (4) and the annular groove (3-1) of stop nut (3) cooperation and the tooth (3-2) of stop nut (3) with
The tooth (2-3) of lock washer (2) meshes together, then nut (1) is bolted in compression stop nut (3) on bolt (4).
As shown in fig. 6, in practical applications, the requirement due to different fasteners for screw-down torque is different, stop nut
(3) tooth (2-3) of tooth (3-2) and lock washer (2) cannot be at a fully engaged, that is, partially engaged state is in, at this time due to tooth
The isosceles triangular structure of (3-2) and tooth (2-3) remains to the loosening for stopping stop nut (3), and nut (1) compresses lock washer
(2), the loosening of stop nut (3) is further hindered.
The above, only the utility model preferred embodiment, is not intended to limit the utility model, i.e., according to this reality
Within novel spirit and principle, any modification, same replacement, improvement for being made etc. should all include the guarantor of the utility model
Within the scope of shield.
