A kind of simple stopping screw proposed by the present invention, including plug, bolt and with the matched nut of bolt thread;Bolt is internally provided with the through-hole through bolt both ends, and through-hole is polygonal hole;Nut is internally provided with the counterbore being connected to internal thread hole, and counterbore is projected as polygonal hole on nut end face;In the state that nut is connect with bolt thread, projection of the counterbore in the plane perpendicular to bolt axis is located inside through-hole;Plug is made of the first cylinder being fixedly connected and the second cylinder, and the first cylinder is interference fitted with through-hole, and the second cylinder is and the matched polygon-prism of counterbore.The present invention is coordinated by the polygon of plug and bolt and nut, de- caused by preventing nut from being inverted with bolt thread to move back;Simultaneously as the first cylinder is interference fitted with through-hole, to ensure that plug and bolted stabilization, retaining effect of the plug to nut is further ensured.
Description
Technical field
The present invention relates to screw technique field more particularly to a kind of simple stopping screws.
Background technology
Bolt nut is the common fastener of machinery field, feature wide with use scope, easy to operate.But
Bolt nut is susceptible to the case where screw thread reversely rotates, to lead using being threadedly coupled during machine movement or vibrations
It causes nut to be detached from bolt, is unfavorable for machine security.
For case above, currently, occurring a variety of anti-backing type bolts in the market, screw thread can be effectively prevent to invert, to
Avoid screw cap-falling.But currently, the anti-backing type bolt occurred in the market, complicated, high processing costs, and be inconvenient to pacify
Dress, so, it is difficult to it promotes.
Invention content
Technical problems based on background technology, the present invention propose a kind of simple stopping screw.
A kind of simple stopping screw proposed by the present invention, including plug, bolt and with the matched nut of bolt thread;Bolt
It is internally provided with the through-hole through bolt both ends, through-hole is polygonal hole;
Nut is internally provided with the counterbore being connected to internal thread hole, and counterbore is projected as polygonal hole on nut end face;Spiral shell
In the state that cap is connect with bolt thread, projection of the counterbore in the plane perpendicular to bolt axis is located inside through-hole;
Plug is made of the first cylinder being fixedly connected and the second cylinder, and the first cylinder is interference fitted with through-hole, the second column
Body be and the matched polygon-prism of counterbore.
Preferably, the length of the first cylinder is equal to the length of through-hole, and the length of the second cylinder is equal to the depth of counterbore.
Preferably, the center overlapping of axles of the central shaft of through-hole and the first cylinder.
Preferably, through-hole is regular polygon hole, and the first cylinder is regular polygon prism.
Preferably, counterbore is regular polygon hole, and the second cylinder is regular polygon prism
Preferably, the second cylinder and the first cylinder are coaxially disposed.
Preferably, the second cylinder is interference fitted with counterbore.
When a kind of simple stopping screw work proposed by the present invention, bolt and nut are normally connected, then, plug is inserted
Enter through-hole, and beat plug, until the second cylinder is inserted into counterbore.In this way, since the first cylinder and through-hole polygon coordinate, the
Two cylinders coordinate with counterbore polygon so that, bolt and nut will not be rotated relative to plug, to prevent nut and bolt
It is de- caused by screw thread reversion to move back;Simultaneously as the first cylinder and through-hole are interference fitted, to ensure that plug with it is bolted
Stablize, further ensures retaining effect of the plug to nut.In addition, in the present invention, the first cylinder cooperatively forms reality with bolt
The bolt arrangement of body is conducive to that bolt is avoided to deform, to ensure the reliability of working bolt.
Description of the drawings
Fig. 1 is a kind of simple stopping screw structure chart proposed by the present invention;
Fig. 2 is bolt vertical view in Fig. 1;
Fig. 3 is nut vertical view in Fig. 1;
Fig. 4 is plug upward view in Fig. 1.
Specific implementation mode
Referring to Fig.1, a kind of simple stopping screw proposed by the present invention, including plug 1, bolt 2 and matched with 2 screw thread of bolt
Nut 3.Bolt 2 is internally provided with the through-hole 20 through 2 both ends of bolt, and through-hole 20 is polygonal hole.
Nut 3 is internally provided with the counterbore 30 being connected to internal thread hole, and counterbore 30 is projected as polygon on 3 end face of nut
Hole.In the state that nut 3 is threadedly coupled with bolt 2, projection of the counterbore 30 in the plane perpendicular to 2 axis of bolt is located at through-hole
Inside 20.
Plug 1 is made of the first cylinder 11 being fixedly connected and the second cylinder 12, and the first cylinder 11 is matched with 20 interference of through-hole
It closes, the second cylinder 12 is and 30 matched polygon-prism of counterbore.
The simple stopping screw that present embodiment provides when work, bolt 2 and nut 3 is normally connected, then, will be inserted
Bolt 1 is inserted into through-hole 20, and beats plug 1, until the second cylinder 12 is inserted into counterbore 30.In this way, due to the first cylinder 11 and leading to
Hole 20 polygon cooperation, the second cylinder 12 coordinate with 30 polygon of counterbore so that, bolt 2 and nut 3 will not be relative to plugs
1 rotation is moved back to prevent nut 3 and 2 screw thread of bolt from inverting caused take off;Simultaneously as the first cylinder 11 and 20 interference of through-hole
Cooperation further ensures retaining effect of the plug 1 to nut 3 to ensure that stabilization that plug 1 is connect with bolt 2.
In present embodiment, the first cylinder 11 cooperatively forms the bolt arrangement of entity with bolt 2, is conducive to that bolt is avoided to become
Shape, to ensure the reliability of the work of bolt 2.In present embodiment, the length of the first cylinder 11 is equal to the length of through-hole 20, the
The length of two cylinders 12 is equal to the depth of counterbore 30, to ensure filling of first cylinder 11 to bolt 2, and ensures the second cylinder 12
With the matching depth of nut 3, to improve retaining effect of the plug 1 to nut 3.
In present embodiment, the center overlapping of axles of the central shaft of through-hole 20 and the first cylinder 11.To ensure the circumferential direction of bolt 2
Uniform force, to ensure the reliability of its work.Further, through-hole 20 is regular polygon hole, and the first cylinder 11 is just more
Side shape prism.
In present embodiment, counterbore 30 is regular polygon hole, and the second cylinder 12 is regular polygon prism, to facilitate installation.
And second cylinder 12 and the first cylinder 11 be coaxially disposed.Meanwhile second cylinder 12 be interference fitted with counterbore 30, further to protect
Demonstrate,prove the connection reliability of plug 1 and nut 3.
The above, preferable specific implementation mode only of the present invention, but protection scope of the present invention not office
Be limited to this, any one skilled in the art in the technical scope disclosed by the present invention, the technique according to the invention
Scheme and its inventive concept are subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
