Abstract

The utility model discloses an anti-theft bolt and a transition bolt head, wherein the anti-theft bolt comprises a bolt bar and a cylindrical bolt head which is connected with the bolt bar as a whole, and at least three clamp holes are circumferentially arranged on the end surface of the bolt head. The transition bolt head is of a regularly hexagonal cylinder, and chucks matched with the clamp holes are integrally arranged on the end surface of the transition bolt head. The anti-theft bolt is used for fixing wheels on axles, the anti-theft function of the bolt can be increased, and the wheels can be prevented from being disassembled and stolen.

Description

Anti-theft bolt and transition bolt head

Technical field

The utility model relates to auto parts machinery, is specifically related to a kind of anti-theft bolt for fastening wheel and transition bolt head.

Background technique

Automotive wheel is to be bolted on the car rotation in wheel hub, because the bolt head of bolt is generally the positive hexagonal prism body of rule, and is exposed to outside the wheel hub, during detaching tyre, only needs can back out bolt with socket wrench, thereby wheel is unloaded.If therefore automobile parking is in unserviced open air, wheel is easy to be stolen, thereby causes certain economic loss and bring certain trouble to the car owner.

Summary of the invention

The purpose of this utility model provides a kind of anti-theft bolt, is used for fixing on axletree of wheel, to increase the anti-theft feature of bolt, prevents from that wheel is removed to steal.

Another purpose of the present utility model provides a kind of and described anti-theft bolt and supports the use, the transition bolt head that anti-theft bolt can be backed out.

Anti-theft bolt described in the utility model comprises bolt shank and the cylindrical bolt head that combines as a whole with bolt shank, circumferentially offers at least three hole clippings on the end face edge of bolt head.

Described hole clipping is the long strip hole, and it is radial arrangement at the bolt head end face.

Transition bolt head described in the utility model for positive hexagonal prism body, is wholely set the dop that is complementary with described hole clipping at its end face.

Dop and hole clipping are complementary, and refer to that the quantity of dop and hole clipping is identical, shape is identical, and the position is corresponding, and dop can carry out Spielpassung with hole clipping.

During use, the dop of transition bolt head is inserted in the hole clipping of anti-theft bolt, block and rotate the transition bolt head with common wrench, anti-theft bolt can be screwed off.

Anti-theft bolt described in the utility model, because its bolt head is cylindrical body, use common wrench it can't be screwed off, and must be by transition bolt head described in the utility model, the two is used and could anti-theft bolt be screwed off with common wrench, so this anti-theft bolt is used for fixing on axletree of wheel, has preferably anti-theft feature, can prevent from effectively that wheel is removed to steal.

Description of drawings

Fig. 1 is that the master of anti-theft bolt looks schematic representation in the utility model;

Fig. 2 is the plan view of Fig. 1;

Fig. 3 is that the master of transition bolt head in the utility model looks schematic representation;

Fig. 4 is the left view of Fig. 3.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Anti-theft bolt as depicted in figs. 1 and 2 comprises bolt shank 1 and the cylindrical bolt head 2 that combines as a whole with bolt shank, and circumferentially offering 3, six hole clippings of six hole clippings 3 on the end face edge of bolt head 2 is the long strip hole, and it is radial arrangement at bolt head 2 end faces.

Such as Fig. 3 and the described transition bolt head of Fig. 4, for positive hexagonal prism body 5, be wholely set six dops 4 that are complementary with described hole clipping 3 at its end face, namely six dops 4 are identical with six hole clipping 3 shapes on the anti-theft bolt, the position is corresponding, and dop 4 can carry out Spielpassung with hole clipping 3.

Claims

1. anti-theft bolt, comprise bolt shank (1) and with the cylindrical bolt head (2) that bolt shank combines as a whole, it is characterized in that: at the end face of bolt head along circumferentially offering at least three hole clippings (3).

2. described anti-theft bolt according to claim 1, it is characterized in that: described hole clipping (3) is the long strip hole, and it is radial arrangement at bolt head (2) end face.
