[technical field]
The present invention relates to the technical fields of bolt, the especially technical field of railroad track anti-theft bolt.
[background technique]
Railroad track, abbreviation rail, rail, track etc., be used for railway, and with railway switch cooperation, enable train without turn
To just capable of walking.Track is usually made of two parallel rail, and rail fixation is placed on sleeper, is cut under sleeper for road, steel
Rail is bolted with sleeper needs, and some criminals can go bolt, the sleeper etc. of stealing rail to go to sell for money to seek profit,
Existing railway fixing bolt anti-theft performance is bad, it is easy to just can dismantle, it is desirable to can propose a kind of railway that anti-theft performance is good
Track bolt.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, a kind of railroad track anti-theft bolt is proposed, it can
Enhance the anti-theft performance of bolt, reduces due to stealing the property loss generated.
To achieve the above object, the invention proposes a kind of railroad track anti-theft bolt, including it is screw rod, interior screw head, outer
Screw head, several link blocks, the screw rod are cylindrical type, and the screw rod outer surface coiling is equipped with external screw thread, the screw rod
Top is equipped with interior screw head, and the interior screw head outer ring is equipped with outer screw head, if passing through involvement between the outer screw head and interior screw head
Connect block connection.
Preferably, the interior screw head is the collar plate shape of smooth outer surface, the diameter of the interior screw head is greater than described
Screw rod diameter.
Preferably, the interior screw head lower end surface is equipped with several anti-skidding latches.
Preferably, the outer screw head outer ring is regular quadrangle or regular hexagon, being equipped in the outer screw head can be with
With the hollow-out parts of interior screw head cooperation.
Preferably, the both ends of the link block are connect with interior screw head and outer screw head respectively, the link block with it is interior
The contact area of screw head is less than the contact area with outer screw head.
Preferably, the link block at least there are three, the link block is placed equidistant with around interior screw head.
It is the screw rod, interior preferably, the center line of the screw rod, interior screw head, outer screw head is on same axis
Screw head, outer screw head are arranged concentrically.
Preferably, the screw rod is an integral molding structure with interior screw head.
A kind of railroad track anti-theft bolt of the present invention the utility model has the advantages that the present invention pass through by screw rod upper end be arranged in screw head
With outer screw head, interior screw head and outer screw head are connected by link block, outer screw head is turned by spanner and fixes bolt, when bolt is solid
It can continue to turn bolt after fixed, disconnect the junction of link block and interior screw head, interior screw head is smooth collar plate shape, is not had
Force can not turn bolt, and anti-theft performance is outstanding.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is a kind of railroad track anti-theft bolt structural schematic diagram main view of the present invention；
Fig. 2 is a kind of railroad track anti-theft bolt structural schematic diagram top view of the present invention.
In figure: screw head, 3- outer screw head, 4- link block, 11- external screw thread, the anti-skidding latch of 21-, 31- hollow out in 1- screw rod, 2-
Portion.
[specific embodiment]
Refering to fig. 1 and Fig. 2, a kind of railroad track anti-theft bolt of the present invention, including screw rod 1, interior screw head 2, outer screw head 3,
Several link blocks 4, the screw rod 1 are cylindrical type, and 1 outer surface of the screw rod coiling is equipped with external screw thread 11, the screw rod 1
Top is equipped with interior screw head 2, and 2 outer ring of interior screw head is equipped with outer screw head 3, if passing through between the outer screw head 3 and interior screw head
Dry link block 4 connects, and the interior screw head 2 is the collar plate shape of smooth outer surface, and the diameter of the interior screw head 2 is greater than described
The diameter of screw rod 1,2 lower end surface of interior screw head are equipped with several anti-skidding latches 21, and 3 outer ring of outer screw head is regular quadrangle
Or regular hexagon, the outer screw head 3 is interior to be equipped with the hollow-out parts 31 that can cooperate with interior screw head 2, the both ends of the link block 4
It is connect respectively with interior screw head 2 and outer screw head 3, the contact area of the link block 4 and interior screw head 2 is less than to be connect with outer screw head 3
Contacting surface product, the link block 4 at least there are three, the link block 4 is placed equidistant with around interior screw head 2, the screw rod 1, interior
Screw head 2, outer screw head 3 center line on same axis, the screw rod 1, interior screw head 2, outer screw head 3 are arranged concentrically, described
Screw rod 1 be an integral molding structure with interior screw head 2.
The course of work of the present invention:
A kind of railroad track of the present invention during the work time, is fixed with anti-theft bolt needed for the screw rod 1 of bolt is aligned
Screw hole blocks outer screw head 3 by spanner, turns bolt, bolt is tightened, bolt tighten after continues to twist, due to link block 2 with
