Abstract
The invention discloses a kind of nut with locking functions, including nut body, multiple elastic bumps are additionally provided with any one end face of the nut body, during nut body fastens elastic deformation can occur for the elastic bumps.In this structure, the nut body of setting is used to be connected with screw flight, the connection being connected with each other with fastening.In this structure, by setting elastic bumps on the end face of nut body either end, so, during nut is tightened, elastic bumps contact with workpiece occurs elastic deformation, the prestressing force that elastic force caused by above elastic deformation can be locking as nut body, so, this bolt is not in the case where matching using cushion, it may have good anti-loosening ability.
Description
Technical field
The present invention relates to mechanical fastener technical field, more particularly to a kind of nut with locking functions.
Background technology
Bolt is the cylindrical threaded fastener of a kind of machine components, usually adapted nut.Bolt by head and
Screw rod（With externally threaded cylinder）Two parts form, and need to coordinate with nut during use, for being fastenedly connected two with leading to
The part in hole, this type of attachment claim bolt connection.It as nut is screwed off from bolt, can separate the two parts again,
Therefore bolt connection is to belong to be detachably connected.By the force way point of connection：It is point common and have articulation hole.By head shape
Shape point：There is turret head, round end, square spigot, countersunk head etc..Wherein turret head is the most frequently used.
At present, for bolted locking, a kind of more universal form is to use elastic washer.But in reality
In maintenance process or assembling process, particularly in maintenance process, often because the carelessness or not responsible of maintainer, does not have
Elastic washer is sheathed on bolt, causes tie point to be relaxed under vibrations, the situation for seal failure or connection relaxation occur goes out
It is existing.
The content of the invention
For it is above-mentioned in the prior art reality maintenance process or assembling process in, particularly in maintenance process, warp
Elastic washer can be often sheathed on bolt, causes tie point under vibrations because of the carelessness or not responsible of maintainer
Absent-mindedness, there is the situation produced problem of seal failure or connection relaxation, the invention provides a kind of spiral shell with locking functions
Cap.
A kind of nut with locking functions provided by the invention solves problem by following technical essential：One kind has
The nut of locking functions, including nut body, multiple elastic bumps are additionally provided with any one end face of the nut body,
During nut body fastens elastic deformation can occur for the elastic bumps.
In this structure, the nut body of setting is used to be connected with screw flight, the connection being connected with each other with fastening.This structure
In, by setting elastic bumps on the end face of nut body either end, so, during nut is tightened, elasticity is convex
Rise to contact with workpiece and elastic deformation occurs, the prestressing force that elastic force caused by above elastic deformation can be locking as nut body,
So, this bolt is not in the case where matching using cushion, it may have good anti-loosening ability.
Further technical scheme is：
To cause above prestressing force to be uniformly distributed in the circumference of nut body, the elastic bumps relative to nut body axle
Line is annularly uniform.
Further technical scheme, the elasticity are uniformly distributed in the circumference of nut body as above prestressing force is caused
Raised number is more than 3.
As a kind of bolt pattern for being easy to processing and manufacturing, the nut body and elastic bumps are formed by casting
Overall structure.
The invention has the advantages that：
In this structure, the nut body of setting is used to be connected with screw flight, the connection being connected with each other with fastening.In this structure,
By setting elastic bumps on the end face of nut body either end, so, during nut is tightened, elastic bumps with
Workpiece contact generation elastic deformation, the prestressing force that elastic force caused by above elastic deformation can be locking as nut body, so,
This bolt is not in the case where matching using cushion, it may have good anti-loosening ability.
Brief description of the drawings
Fig. 1 is a kind of structural representation of one specific embodiment of nut with locking functions of the present invention.
Numbering in figure is followed successively by：1st, nut body, 2, elastic bumps.
Embodiment
With reference to embodiment, the present invention is described in further detail, but the present invention structure be not limited only to it is following
Embodiment.
Embodiment 1：
As shown in figure 1, a kind of nut with locking functions, including nut body 1, any one end of the nut body 1
Multiple elastic bumps 2 are additionally provided with face, during nut body 1 fastens elastic deformation can occur for the elastic bumps 2.
In this structure, the nut body 1 of setting is used to be connected with screw flight, the connection being connected with each other with fastening.This knot
In structure, by setting elastic bumps 2 on the end face of the either end of nut body 1, so, and during nut is tightened, bullet
Property projection 2 contacted with workpiece generation elastic deformation, what elastic force caused by above elastic deformation can be locking as nut body 1 is pre-
Stress, so, this bolt is not in the case where matching using cushion, it may have good anti-loosening ability.
Embodiment 2：
As shown in figure 1, the present embodiment is further qualified on the basis of embodiment 1：To cause above prestressing force in nut sheet
It is uniformly distributed in the circumference of body 1, the elastic bumps 2 are annularly uniform relative to the axis of nut body 1.
Further technical scheme, the bullet are uniformly distributed in the circumference of nut body 1 as above prestressing force is caused
Property projection 2 number be more than 3.
As a kind of bolt pattern for being easy to processing and manufacturing, the nut body 1 and elastic bumps 2 are to be formed by casting
Overall structure.
Above content is to combine the further description that specific preferred embodiment is made to the present invention, it is impossible to assert this
The embodiment of invention is confined to these explanations.For general technical staff of the technical field of the invention,
The other embodiment drawn in the case where not departing from technical scheme, should be included within the scope of the present invention.
