Description
[technical field]
The present invention relates to the technical fields of the technical field of fastener, especially anti-theft nut.
[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 needs to fix by bolts and nuts with sleeper, and some criminals can remove to steal bolt and nut, the rail of rail to seek profit
Pillow etc. goes to sell for money, and existing railway fixture nut anti-theft performance is bad, it is easy to just can dismantle, it is desirable to can propose a kind of anti-theft
The good railroad track nut of energy.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, a kind of track antitheft spiral shell of non-dismountable type is proposed
Mother can enhance the anti-theft performance of railway nut, reduce due to stealing the property loss generated.
To achieve the above object, the invention proposes a kind of non-dismountable type anti-theft nut of track, including nut inner ring,
Nut outer ring, several link blocks, the nut inner ring are circular ring type, and the inner ring inner ring circle wall coiling is equipped with internal screw thread,
The nut inner ring outer ring is equipped with nut outer ring, and the nut outer ring is connect with nut inner ring by several link blocks.
Preferably, the nut inner ring lower end surface is equipped with several anti-loosening raised lines.
Quadrangle or regular hexagon preferably, the outer ring cross-section of the nut outer ring is positive, in the nut outer ring
Equipped with the hollow-out parts that can cooperate with nut inner ring.
Preferably, the contact area of the link block and nut inner ring is less than the contact area with nut outer ring.
Preferably, the link block both ends are respectively stub end and small head end, the stub end and nut outer ring
It is fixedly connected, the small head end is fixedly connected with nut inner ring.
Preferably, the link block at least there are three, the spaced winding nut inner ring etc. of the link block and link block
Away from setting.
Preferably, the center line of the nut inner ring and nut outer ring is on same axis, nut inner ring and spiral shell
Female outer ring is arranged concentrically.
Preferably, the nut inner ring, nut outer ring and link block surface are plated with antirust coat.
The non-dismountable type anti-theft nut of a kind of track of the invention the utility model has the advantages that the present invention by setting spiral shell for nut
Female inner ring and nut outer ring double-layer structure are connected nut inner ring with nut outer ring by link block, pass through spanner card when tightening
Firmly nut outer ring turns, and can continue to turn after nut is tightened, until the connection of link block and nut inner ring disconnects, nut
Inner ring is smooth circular ring type, and no impetus turns, and nut inner ring just can not be dismantled, anti-theft performance is good.
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 non-dismountable type anti-theft nut structural schematic diagram top view of track of the invention；
Fig. 2 is a kind of non-dismountable type anti-theft nut structural schematic diagram main view of track of the invention.
In figure: the anti-loosening raised lines of 1- nut inner ring, 2- nut outer ring, 3- link block, 11- internal screw thread, 12-, 21- are engraved
Empty portion, 31- stub end, the small head end of 32-.
[specific embodiment]
Refering to fig. 1 and Fig. 2, the non-dismountable type anti-theft nut of a kind of track of the invention, including outside nut inner ring 1, nut
Ring 2, several link blocks 3, the nut inner ring are circular ring type, and 1 inner ring circle wall of the inner ring coiling is equipped with internal screw thread 11, institute
The nut inner ring outer ring stated is equipped with nut outer ring 2, and the nut outer ring 2 is connect with nut inner ring 1 by several link blocks 3,
1 lower end surface of nut inner ring is equipped with several anti-loosening raised lines 12, and the outer ring cross-section of nut outer ring 2 is positive four sides
Shape or regular hexagon, the nut outer ring 2 is interior to be equipped with the hollow-out parts 21 that can cooperate with nut inner ring 1, the link block 3
It is less than the contact area with nut outer ring 2 with the contact area of nut inner ring 1,3 both ends of link block are respectively stub end
31 are fixedly connected with small head end 32, the stub end 31 with nut outer ring 2, and the small head end 32 and nut inner ring 1 are fixed
Connection, the link block 3 at least there are three, the spaced winding nut inner ring 1 of the link block 3 and link block is placed equidistant with, institute
On same axis, nut inner ring 1 and nut outer ring 2 are arranged concentrically the center line of the nut inner ring 1 and nut outer ring 2 stated,
Nut inner ring 1, nut outer ring 2 and 3 surface of link block is plated with antirust coat.
The course of work of the present invention:
Nut during the work time, is equipped with anti-loosening raised line with non-dismountable type anti-theft nut by a kind of track of the present invention
Fixed bolt, the nut outer ring 2 of nut is blocked by spanner, bolt is tightened, bolt is tightened needed for one end alignment on road 12
Continue to turn later, until the connection of link block 3 and nut inner ring 1 disconnects, removes link block 3 and nut outer ring 2, nut inner ring
