Abstract
A non-standard anti-dismantle bolt and a special purpose spanner solve the technical problems that standard tools cannot dismantle bolts. The technical solution is that the non-standard anti-dismantle bolt comprises a screw stem and a nut cap, wherein an inscribed polygon spanner jack is arranged on the nut cap, a projection which has the coaxial line with the nut cap is arranged in the inscribed polygon spanner jack on the nut cap, the external profile of the nut cap is of cylinder shape, the shape of the connection end of the special purpose spanner and the non-standard anti-dismantle bolt corresponds to the shape of the inscribed polygon spanner jack of the non-standard anti-dismantle bolt, and an inner hole which corresponds to the projection which is arranged in the inscribed polygon spanner jack of the non-standard anti-dismantle bolt is arranged on the bolt connection end. The non-standard anti-dismantle bolt and the special purpose spanner have the advantages of simple manufacture of non-standard anti-dismantle bolts and special purpose spanners, fully uses the prior standard production equipment and processes, lowers cost of manufacture, achieves the corresponding of spanners and bolts through changing shapes or sizes of anti-dismantle structures, and reaches the purpose of anti-dismantle. The added non-standard anti-dismantle structure has simple shape and is easy to process.
Description
Affiliated technical field
The utility model relates to a kind of connection with bolt and special spanner, particularly a kind of nonstandard tamper bolt and special spanner 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, as the stringing pylon, public guardrail reaches in the linkage structure that prevents to steal, 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, and when using the special spanner demounting bolt inconvenience.
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 and special spanner, this nonstandard tamper bolt arrangement and special spanner have on the basis of structure characteristic of standard bolt and spanner, set up nonstandard tamper structure, 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, nut be provided with inner polygon spanner jack, in the described projection that is provided with in the inner polygon spanner jack on nut with the nut coaxial line, the external frame of nut is cylindrical.
Nonstandard tamper bolt special spanner, at described special spanner and nonstandard tamper bolt connecting end is corresponding with the shape of nonstandard tamper bolt inner polygon spanner jack, the bolt connecting end be provided with nonstandard tamper bolt inner polygon spanner jack in the protruding corresponding endoporus that is provided with.
The beneficial effects of the utility model are, because this nonstandard tamper bolt arrangement and special spanner have the structure characteristic of standard bolt and spanner, make nonstandard tamper bolt and special spanner manufacturing simple, make full use of existing standard manufacturing mechanism and technology, reduce manufacture cost, the nonstandard tamper structure shape of Zeng Jiaing is simple simultaneously, easy processing, shape or size 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.
Description of drawings
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing 1 is the nonstandard tamper bolt of a utility model schematic representation.
Accompanying drawing 2 is the nonstandard tamper bolt of a utility model generalized section.
Accompanying drawing 3 is the nonstandard tamper bolt axis of a utility model mapping.
Accompanying drawing 4 is the utility model special spanner schematic representation.
Accompanying drawing 5 is the utility model special spanner generalized section.
In the accompanying drawing, 1 nut, 2 polygonal spanner jacks, 3 projectioies, 4 bolt connecting ends, 5 endoporus.
Embodiment
Referring to accompanying drawing, a kind of nonstandard tamper bolt comprises: screw rod and nut, nut be provided with inner polygon spanner jack, in the described projection 3 that is provided with in the inner polygon spanner jack 2 on nut 1 with nut 1 coaxial line, the external frame of nut 1 is cylindrical.
During use, owing on nut 1, be provided with projection 3 in the inner polygon spanner jack 2 with nut 1 coaxial line, the effect of projection 3 can't enter in the polygonal spanner jack 2 spanner of standard, and the standard spanner of reaching can't be implemented the goal of the invention to the dismounting of nonstandard tamper bolt.
The utility model at described inner polygon spanner jack 2, is the hexagonal wrench jack for ease of the manufacturing of nonstandard tamper bolt, and the projection 3 that is provided with in inner polygon spanner jack 2 is cylindrical or conical.
The utility model is for solving the influence of 3 pairs of nonstandard tamper bolt profiles of projection, and projection 3 height that are provided with in described inner polygon spanner jack 2 are less than the degree of depth of inner polygon spanner jack 2.Guarantee that projection 3 is in the polygonal spanner jack 2 fully.
Nonstandard tamper bolt special spanner, at described special spanner and nonstandard tamper bolt connecting end 4 is corresponding with the shape of the described inner polygon spanner of nonstandard tamper bolt jack 2, and bolt connecting end 4 is provided with the endoporus 5 corresponding with the projection 3 on the nonstandard tamper bolt.
During use, endoporus 5 is enclosed within on the projection 3, and special spanner and nonstandard tamper bolt connecting end 4 enter in the polygonal spanner jack 2 of nonstandard tamper bolt, moves nonstandard tamper bolt and rotates the dismounting that realizes nonstandard tamper bolt.
The purpose that the utility model can be realized tamper by the shape or the size of change projection 3 and endoporus 5, special spanner also has the effect of the dismounting key of tamper bolt simultaneously.
