Description
Technical field
It the utility model is related to a kind of bolt, and in particular to a kind of bolt.
Background technology
Bolt:Machine components, the cylindrical threaded fastener of adapted nut.External screw thread (is carried by head and screw rod
Cylinder) a kind of fastener dimerous, need to coordinate with nut, for be fastenedly connected two carry through hole parts.
This type of attachment claims bolt connection.It as nut is screwed off from bolt, can separate the two parts again, therefore bolt connection
It is to belong to be detachably connected.
Easily there is situation about loosening when in use in existing bolt, and when the environment for needing to seal uses
Wait (such as on automobile), sealing is poor.
Utility model content
In order to overcome the shortcomings of background technology, the utility model provides a kind of bolt, it is easy mainly to solve bolt
The problem of loosening, the bolt not only have positioning energy well by setting locating dowel and rubber blanket on bolt
Power, the problem of can be good at preventing bolt from loosening, and there is good sealing property, there is simple in construction, processing side
Just, the advantages of cost is cheap.
Technical scheme is used by the utility model：A kind of bolt, including bolt head and screw rod, in the bolt
The screw rod at first end is provided with the step being close to bolt head, and rubber blanket is set with described step outer ring, the step
Downside end face is provided with groove, is provided with spring and locating dowel in described groove, described spring one end is fixed with groove, another
End is fixed with locating dowel, and described bolt head is provided with hexagonal counterbore, and the through hole through screw rod is provided with described counterbore, described
Through hole both sides be provided with divide hole.
Further, described counterbore is provided with capping, and described capping is hinged with bolt head by hinge.
Further, described rubber blanket is the umbrella-shaped structure with mounting hole, described mounting hole size and step
Size is consistent.
Further, the external diameter of described rubber blanket is less than the external diameter of bolt head.
Further, described screw rod includes the polished end and the end of thread of upper end, and a described point hole is arranged on the end of thread,
Its number at least two.
Further, a described point hole tilts down setting.
The beneficial effects of the utility model are：Due to taking above-mentioned technical proposal, the bolt on bolt by setting
Locating dowel and rubber blanket are put, not only with good stationkeeping ability, the problem of can be good at preventing bolt from loosening, and
There is good sealing property, there is simple in construction, easy to process, the advantages of cost is cheap.

Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of bolt, including bolt head 1 and screw rod 2, on the screw rod 2 of described one end of bolt head 1
Provided with the step 3 being close to bolt head 1, rubber blanket 4 is set with the described outer ring of step 3, the class of rubber blanket 4 when installation
Play a part of sealing like sealing ring；The downside end face of the step 3 is provided with groove 5, and spring 6 is provided with described groove 5
With locating dowel 7, described one end of spring 6 is fixed with groove 5, and the other end is fixed with locating dowel 7, and described bolt head 1 is provided with
Hexagonal counterbore 8, locating dowel 7, which is used to coordinate with the aperture on fixture, to be positioned and is fixed, and prevents bolt from occurring what is loosened
Problem；The through hole 9 through screw rod 2 is provided with described counterbore 8, the described both sides of through hole 9, which are provided with, divides hole, and bolt is solid in long-time
After fixed occur that the problem of stuck of getting rusty occurs, injection lubricating oil can be now lubricated in through hole 9.
In the utility model, described counterbore 8 is provided with capping 11, and described capping 1 is cut with scissors with bolt head 1 by hinge
Connect；Described rubber blanket 4 is the umbrella-shaped structure with mounting hole, and described mounting hole size is consistent with the size of step, institute
The external diameter for the rubber blanket 4 stated is less than the external diameter of bolt head 1, and the rubber blanket 4 of this structure is similar to the effect of sucker, with bolt head 1
Inwall extruding fitting, improves sealing property.
In the utility model, described screw rod 2 includes the polished end 12 and the end of thread 12 of upper end, and described point hole 10 is set
Put on the end of thread 13, its number at least two；Described point hole 10 tilts down setting.
The bolt, can not only with good stationkeeping ability by setting locating dowel and rubber blanket on bolt
The problem of preventing bolt from loosening well, and have good sealing property, there is simple in construction, easy to process, cost
The advantages of cheap.
Every technical staff's notice：Although the utility model describes according to above-mentioned embodiment, this
The invention thought of utility model is not limited to that utility model, any repacking with inventive concept, will all include this specially
