Abstract

A kind of screw rod, it is characterised in that：It is made up of shaft, central through hole, cross recess, head.A kind of expansion rod, it is characterised in that：It is made up of guide rod, annulus, cross-bar, expansion-head.A kind of check bolt, it is characterised in that：It is made up of screw rod, such as right expansion rod, nut.The cardinal principle of the present invention：Promoted with the expansion rod that is screwed into of nut, expansion-head is screw rod tail expansion, and is kept, and nut can not be exited in vibrations.Beneficial effects of the present invention：Available for mining machinery, will not be released because of vibrations.

Description

Available for the screw rod of macroseism environment or mining machinery, expansion rod, check bolt
Technical field
The invention belongs to bolt, specific design can be used for screw rod, expansion rod, the locking spiral shell of macroseism environment or mining machinery Bolt.
Background technology
Macroseism environment and mining machinery vibrations are serious, and bolt is easily loose, are worth improving.
The content of the invention
The purpose of the present invention is to solve the shortcomings of the prior art propose the screw rod available for macroseism environment or mining machinery, Expansion rod, check bolt.It can be additionally used on some fasteners of earthquake prone district.
The present invention has technology contents：
1st, a kind of screw rod, it is characterised in that：It is made up of shaft, central through hole, cross recess, head；Shaft is cylindric, table Face has screw thread；Head is located at one end of shaft；Central through hole is axially disposed within the symmetry axis of shaft, central through hole bar Body and head；Cross recess is axially disposed within the symmetry axis of shaft.
2nd, a kind of expansion rod, it is characterised in that：It is made up of guide rod, annulus, cross-bar, expansion-head；Internal radius, which is more than, leads Bar external diameter, is connected between guide rod and annulus by cross-bar, and guide rod, annulus, cross-bar three are coaxial；Expansion-head is connected to guide rod end End, expansion-head is in annular direction with having wedging inclined-plane on guide rod link position；Opposite direction of the cross-bar in expansion-head direction Above have and be inserted into chamfering.
3rd, a kind of expansion rod as described in technology contents 2, it is characterised in that：Described expansion-head is cylindrical, spherical.
4th, a kind of check bolt, it is characterised in that：As the screw rod as described in technology contents 1, as described in technology contents 2 or 3 Expansion rod, nut form；The diameter of the guide rod of expansion rod is less than or equal to the diameter of pitch through hole, the expansion-head of expansion rod Diameter be more than pitch through hole；The thickness of the cross-bar of expansion rod is less than the width of the cross recess of screw rod；Expansion rod is led Bar inserts pitch through hole；The shaft of nut and screw rod coordinates.
5th, a kind of check bolt as described in technology contents 4, it is characterised in that：Also there is ring between nut and expansion rod Shape spring shim.
Technology contents illustrate and its advantage：
The cardinal principle of the present invention：Promoted with the expansion rod that is screwed into of nut, expansion-head is screw rod tail expansion, and is protected Hold, nut can not be exited in vibrations.In the case of increasing a spring shim, the elastic force after tightening due to spring shim makes Expansion rod is always subjected to inward force, is close to the surface of bolt connection thing, nut can not invert release, can also play it is antitheft Effect.
Beneficial effects of the present invention：Available for mining machinery, will not be released because of vibrations.In some of earthquake prone district On fastener beneficial effect can be obtained using one.
