Abstract
The utility model relates to a non-standard anti-dismounting screw bolt, which solves the technical problem that a screw bolt can not be dismounted by a standard tool. The technical proposal of the non-standard anti-dismounting screw bolt is that; the non-standard anti-dismounting screw bolt comprises a screw rod and a screw cap, the screw cap is a round screw cap, and an incomplete round dismounting groove is arranged on the screw cap. The non-standard anti-dismounting screw bolt has the advantages that: the manufacturing of the non-standard anti-dismounting screw bolt and a special purpose spanner is easy by adopting the structure of the non-standard anti-dismounting screw bolt, the manufacturing cost is reduced, the processing is easy, the correspondence of the screw bolt and the spanner is realized by easily changing the radius of the anti-dismounting structure or the width of the groove, thereby realizing the purpose that the screw bolt can not be dismounted by a standard spanner. The special purpose spanner is a dismounting tool with key functions.
Description
Affiliated technical field
The utility model relates to a kind of connection bolt, particularly a kind of nonstandard tamper bolt that the tamper structure is set on standard bolt.
Background technique
Connecting with bolt is a kind of standard union piece that often uses in structural member, but in the structure of specific (special) requirements is arranged, reach in the linkage structure that prevents to steal as stringing pylon, public guardrail, how to solve and use conventional tool can't dismantle the technical problem that connects with bolt, multiple tamper bolt arrangement is arranged in the prior art, as nut designs being become nonstandard special shape, become nonstandard special shape that the processing of bolt and the corresponding dismounting spanner that uses is made troubles nut designs, increased the manufacture cost of bolt and dismounting spanner greatly.
Summary of the invention
For solving in the structure of specific (special) requirements is arranged, use conventional tool can't dismantle the technical problem that connects with bolt, the utility model designs a kind of nonstandard tamper bolt arrangement, this nonstandard tamper bolt arrangement is simple in structure, easy to process, realize that nonstandard tamper bolt is corresponding with the special spanner structure, have only and use corresponding special spanner, could realize dismounting, reach antitheft and prevent the purpose of dismounting arbitrarily nonstandard tamper bolt.
The utility model realizes that the technological scheme that goal of the invention adopts is; A kind of nonstandard tamper bolt comprises: screw rod and nut, described be lug at nut, nut is provided with incomplete circular dismounting groove.
The beneficial effects of the utility model are, because this nonstandard tamper bolt arrangement, make nonstandard tamper bolt and special spanner manufacturing simple, reduce manufacture cost, easy processing, radius or groove width by simple change tamper structure realize that screw is corresponding with spanner, the goal of the invention that the standard spanner of reaching can't be dismantled.Special spanner becomes the extracting tool with key effect.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing 1 is the nonstandard tamper bolt of a utility model end view.
Accompanying drawing 2 is accompanying drawing 1 sectional view.
Accompanying drawing 3 is the nonstandard tamper bolt axis of a utility model mapping.
In the accompanying drawing, 1 nut, 2 dismounting grooves.
Embodiment
Referring to accompanying drawing, a kind of nonstandard tamper bolt comprises: screw rod and nut, and described is lug at nut 1, nut 1 is provided with incomplete circular dismounting groove 2.
Special spanner inserts dismounting groove 2 during use, and the bolt of rotation special spanner band is realized the screw-in or the dismounting of nonstandard tamper bolt.
The utility model embodiment, the degree of depth of dismounting groove 2 is less than the thickness of nut 1.Have only corresponding special spanner to implement the tamper Bolt dismantling, the tamper effect is better.
The utility model embodiment, dismounting groove 2 increases corresponding special spanner stress surface greater than half of annulus.
Claims (3)
1. nonstandard tamper bolt, comprising: screw rod and nut is characterized in that: described nut (1) is a lug, nut (1) is provided with incomplete circular dismounting groove (2).
2. a kind of nonstandard tamper bolt according to claim 1, it is characterized in that: the degree of depth of described dismounting groove (2) is less than the thickness of nut (1).
