Abstract
The utility model discloses an anti-theft bolt and an ignition switch adopting the same. The anti-theft bolt comprises a screw cap and a screw; at least one pair of clamping grooves are symmetrically formed in the screw cap; a vertical step surface is arranged between each clamping groove along the screwing direction of the bolt and the end surface of the screw cap; a smooth transition inclined surface is arranged between each clamping groove along the opposite direction of the screwing direction of the bolt and the end surface of the screw cap. By virtue of the anti-theft bolt and the ignition switch adopting the anti-theft bolt, the problems that the conventional anti-theft bolt and the ignition switch adopting the anti-theft bolt have high manufacturing precision requirements on the anti-theft bolt, component materials are wasted, the overall cost is high, and specially shaped tools are required for assembly can be effectively solved, and the anti-theft bolt and the ignition switch adopting the anti-theft bolt can be widely applied to the field of the anti-theft bolts.
Description
Technical field
The utility model relates to a kind of bolt, relates in particular to a kind of anti-theft bolt and adopts the ignition switch of this anti-theft bolt.
Background technique
In the assembly process of automobile, often can connect each component with bolt.As the fastener bolt that has is now first, be all hexagon, square etc., the bolt head of this square or hexangle type, because its profile corner angle are clearly demarcated, tool using is not had to special requirement, as long as just can realize to the unscrewing or tighten of bolt, so very extensive in the use by spanner or pliers class.But this bolt is used on field construction, as Infrastructure such as railway, bridge, electric power pylon, microwave communication towers, will be by lawless person as the object of stealing or destroying.In order to ensure safety, prevent stealing and destroy, just there is a kind of anti-theft bolt.And anti-theft bolt, main form has: twist into two parts type anti-theft bolt (or or special-shaped special tool anti-theft bolt.
There is following defect in conventional anti-theft bolt now: twist into two parts type bolt processing request high, guarantee that the power value of regulation is not twisted into two parts, how much power value must be twisted into two parts, and wastes material again, and part holistic cost is high.Special-shaped special tool anti-theft bolt needs special-purpose instrument, uses and gets up to have certain narrow limitation.And adopted the ignition switch of existing anti-theft bolt, also exist above-mentioned problem.
Model utility content
The purpose of this utility model is to provide a kind of anti-theft bolt and adopts the ignition switch of this anti-theft bolt, can effectively solve existing anti-theft bolt and adopt the ignition switch of this anti-theft bolt, accuracy of manufacturing for anti-theft bolt requires high, waste part material, part holistic cost is high, or needs to use the problem of profile tool assembling.
The utility model solves the technological scheme that its technical problem adopts: a kind of anti-theft bolt, comprise nut and screw rod, on described nut, be symmetrically arranged with at least one pair of draw-in groove, described draw-in groove is provided with vertical step surface along between bolt tightening direction and nut end face, and described draw-in groove is provided with level and smooth transition inclined-plane along between the opposite direction of bolt tightening and nut end face.
Further, a kind of ignition switch that adopts above-mentioned anti-theft bolt, comprises ignition switch assembly, the mounting bracket coordinating with automobile pipe column; Described mounting bracket is fixed on ignition switch assembly on automobile pipe column by anti-theft bolt.
The beneficial effects of the utility model: be symmetrically arranged with at least one pair of draw-in groove on the nut of anti-theft bolt, draw-in groove is provided with vertical step surface along between bolt tightening direction and nut end face, draw-in groove is provided with level and smooth transition inclined-plane along between the opposite direction of bolt tightening and nut end face, can guarantee that like this bolt can only unidirectionally tighten, can not unscrew, thereby realized the anti-theft feature of bolt, and the accuracy of manufacturing of anti-theft bolt requires lower, save material, part holistic cost is low, and without using profile tool to assemble.Adopt the ignition switch of above-mentioned anti-theft bolt when external automobile pipe column, can there is good theftproof performance.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of anti-theft bolt.
Fig. 2 is for adopting the structural representation of the ignition switch of anti-theft bolt shown in Fig. 1.
Embodiment
Embodiment, a kind of anti-theft bolt as shown in Figure 1 and Figure 2, comprise nut 2 and screw rod 1, on described nut 2, be symmetrically arranged with at least one pair of draw-in groove 3, described draw-in groove 3 is provided with vertical step surface 4 along between bolt tightening direction and nut 2 end faces, and described draw-in groove 3 is provided with level and smooth transition inclined-plane 5 along between the opposite direction of bolt tightening and nut 2 end faces.Adopt an ignition switch for above-mentioned anti-theft bolt, comprise ignition switch assembly 6, the mounting bracket 8 coordinating with automobile pipe column 7; Described mounting bracket 8 is fixed on ignition switch assembly 6 on automobile pipe column 7 by anti-theft bolt 9.
