Description
Technical field
The present invention relates to mechanical fastener technical field, more particularly to a kind of machine components connector.
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 machine components connector.
A kind of machine components connector provided by the invention solves problem by following technical essential：A kind of machine components
Connector, including screw rod and nut, the nut include nut body, and the bolt includes spiro rod section and is arranged at spiro rod section end
The screw cap end in portion, the screw cap end is on the end face of spiro rod section, nut body be provided with the end face of screw cap end it is more
Individual elastic bumps, the elastic bumps can produce elastic deformation during bolt is tightened.
In this structure, there is screw thread on the spiro rod section of setting, for being threadedly coupled in bolt connection with nut, to fasten phase
The connector to connect, above screw cap end turn part as what operator's brake screw section rotated.In this structure, by spiral shell
Cap end sets elastic bumps on the end face of spiro rod section one end, and so, during bolt is tightened, bullet occurs for elastic bumps
Property deformation, elastic force caused by above elastic deformation can as the prestressing force of screw retention, so, this bolt do not matching use
In the case of cushion, it may have good anti-loosening ability.
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
Elastic bumps are set on the end face of nut body either end, and so, during nut is tightened, elastic bumps connect with workpiece
The raw elastic deformation of triggering, the prestressing force that elastic force caused by above elastic deformation can be locking as nut body, so, this bolt
In the case where not 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 bolt, the elastic bumps on two end faces are both with respect to spiro rod section
Axis it is annularly uniform.
As causing above prestressing force to be uniformly distributed further technical scheme in the circumference of bolt, on two end faces
The number of elastic bumps is all higher than 3.
It is elastic convex in the screw cap end, spiro rod section and screw cap end as a kind of connector form for being easy to processing and manufacturing
Rise is by casting the overall structure formed；Elastic bumps in the nut body and nut body are formed by casting
Overall structure.
The invention has the advantages that：
In this structure, there is screw thread on the spiro rod section of setting, for being threadedly coupled in bolt connection with nut, mutually interconnected with fastening
The connector connect, above screw cap end turn part as what operator's brake screw section rotated.In this structure, by screw cap end
Elastic bumps are set on the end face of spiro rod section one end, so, during bolt is tightened, elastic shape occurs for elastic bumps
Become, elastic force caused by above elastic deformation can be as the prestressing force of screw retention, and so, this bolt is not being matched using elasticity
In the case of pad, it may have good anti-loosening ability.
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
Elastic bumps are set on the end face of nut body either end, and so, during nut is tightened, elastic bumps connect with workpiece
The raw elastic deformation of triggering, the prestressing force that elastic force caused by above elastic deformation can be locking as nut body, so, this bolt
In the case where not 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 machine components connector of the present invention.
Numbering in figure is followed successively by：1st, screw cap end, 2, spiro rod section, 3, elastic bumps, 4, nut body.
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 machine components connector, including screw rod and nut, the nut include nut body 4, the spiral shell
Bolt includes spiro rod section and is arranged at the screw cap end 1 of spiro rod section end, and the screw cap end 1 is on the end face of spiro rod section, nut sheet
Body 4 is provided with multiple elastic bumps 3 on the end face of screw cap end 1, and the elastic bumps 3 can be during bolt be tightened
Produce elastic deformation.
In this structure, there is screw thread on the spiro rod section 2 of setting, for being threadedly coupled in bolt connection with nut, with fastening
The connector of interconnection, above screw cap end 1 turn part as what operator's brake screw section 2 rotated.In this structure, pass through
Elastic bumps 3 are set on the end face of the one end of spiro rod section 2 in screw cap end 1, so, during bolt is tightened, elasticity is convex
Play 3 and elastic deformation occurs, elastic force caused by above elastic deformation can be as the prestressing force of screw retention, and so, this bolt exists
Do not match using in the case of cushion, it may have good anti-loosening ability.
The nut body 4 of setting is used to be connected with screw flight, the connection being connected with each other with fastening.In this structure, pass through
On the end face of the either end of nut body 4 set elastic bumps 3, so, during nut is tightened, elastic bumps 3 with
Workpiece contact generation elastic deformation, the prestressing force that elastic force caused by above elastic deformation can be locking as nut body 4, this
Sample, 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 bolt
It is uniformly distributed in circumference, the elastic bumps 3 on two end faces are annularly uniform both with respect to the axis of spiro rod section 2.
As causing above prestressing force to be uniformly distributed further technical scheme in the circumference of bolt, on two end faces
The number of elastic bumps 3 is all higher than 3.
As a kind of connector form for being easy to processing and manufacturing, the elasticity in the screw cap end 1, spiro rod section and screw cap end 1
Projection 3 is by casting the overall structure formed；Elastic bumps 3 in the nut body 4 and nut body 4 are to pass through casting
The overall structure formed.
Above content is to combine the further description that specific preferred embodiment is made to the present invention, it is impossible to assert this
