Description

Anti-theft bolt

Technical Field

The utility model relates to a bolt, the theftproof bolt that can prevent direct dismantlement specifically says so.

Background

Bolts are widely used in all industries as a kind of fixed connection fastener. At present, the bolt that uses in the trade includes including the double-screw bolt, and this double-screw bolt divide into screw thread section and linkage segment in proper order from its one end to the other end, and the one end of screw thread section is in the same place with the one end butt joint of linkage segment, and it has the external screw thread to process on the lateral surface of screw thread section, and smooth form is personally submitted in the outside of linkage segment, is connected with the nut in the screw thread section, keeps away from one of the linkage segment of screw thread section and serves and be provided. When the bolt is used outdoors, a lawless person can disassemble the bolt by using a common wrench, and the anti-theft effect is poor.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a theftproof bolt, this bolt can not dismantle with ordinary spanner, and the theftproof effect is better.

In order to solve the problems, the following technical scheme is provided:

the utility model discloses a theftproof bolt includes the double-screw bolt, and this double-screw bolt divide into screw thread section and linkage segment in proper order from its one end to the other end within a definite time, and the one end of screw thread section is in the same place with the one end butt joint of linkage segment, and it has the external screw thread to process on the lateral surface of screw thread section, and smooth form is personally submitted in the outside of linkage segment, is connected with the nut in the screw thread section, keeps away from the linkage segment of screw thread section. The nut is characterized in that first grooves are uniformly distributed on the outer side wall of the threaded section along the periphery of the outer side wall, the first grooves penetrate through the axial direction of the threaded section, a second groove penetrating through the axial direction of the nut is arranged on the inner side wall of the nut, the second groove is opposite to one of the first grooves in position, and a bolt is arranged between the second groove and one of the first grooves.

The cross sections of the first groove and the second groove are semicircular, and the diameters of the first groove and the second groove are equal.

The screw cap is hemispherical, the stud is fixed on the plane of the screw cap, the stud is perpendicular to the plane of the screw cap, and the axis of the stud penetrates through the spherical center of the screw cap.

The end surface of the thread section far away from the connecting section is provided with a cross-shaped groove.

By adopting the scheme, the method has the following advantages:

because the utility model discloses an it has first recess to follow its week equipartition on the lateral wall of theftproof bolt screw thread section, and first recess all runs through the axial of screw thread section, have on the inside wall of nut and run through its axial second recess. When the locking device is used, the position of the second groove is adjusted in the locking process, so that after the locking, the second groove is opposite to one of the first grooves, and the bolt is inserted between the second groove and the corresponding first groove. When the bolt is used, the bolt is limited by the bolt, and the bolt cannot be disassembled by a common wrench, so that the anti-theft performance is greatly improved.

Drawings

Fig. 1 is a schematic structural view of the anti-theft bolt of the present invention;

FIG. 2 is a right side view of FIG. 1;

fig. 3 is a three-dimensional exploded view of the anti-theft bolt of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-3, the utility model discloses an anti-theft bolt includes the double-screw bolt, and this double-screw bolt divide into screw thread section 22 and linkage segment 21 in proper order from its one end to the other end, and the one end of screw thread section 22 is in the same place with the one end butt joint of linkage segment 21, and processing has the external screw thread on screw thread section 22's the lateral surface, and smooth form is personally submitted in the outside of linkage segment 21, is connected with nut 4 on the screw thread section 22, and the linkage segment 21 of keeping away from screw thread section 22 serves and is. First grooves 3 are uniformly distributed on the outer side wall of the threaded section 22 along the periphery of the threaded section, the first grooves 3 penetrate through the threaded section 22 in the axial direction, second grooves 6 penetrating through the threaded section in the axial direction are formed in the inner side wall of the nut 4, the second grooves 6 are opposite to one first groove 3, and a bolt 7 is arranged between the second grooves 6 and the first groove 3.

In order to facilitate the insertion of the plug 7, the cross section of the first groove 3 and the cross section of the second groove 6 are semicircular, and the diameters of the two grooves are equal.

In order to further improve the anti-theft effect, the screw cap 1 is hemispherical, the stud is fixed on the plane of the screw cap 1, the stud is perpendicular to the plane of the screw cap 1, and the axis of the stud penetrates through the spherical center of the screw cap 1.

In order to increase the installation, the cross-shaped groove 5 is formed on the end face of the thread section 22 far away from the connecting section 21.

During the use, the second recess 6 position of adjustment among the locking process for after the locking, second recess 6 is relative with the position of one of them first recess 3, insert bolt 7 between second recess 6 and the first recess 3 that corresponds can. When the bolt is used, the bolt 7 is limited, and the bolt cannot be disassembled by a common wrench, so that the anti-theft performance is greatly improved.
