Abstract

The utility model relates to an anti-theft screw of a tyre. The utility model is characterized in that a screw cap-shaped lock body 1.1 is connected with a screw rod 2 which is provided with threads and a dustproof cover 1.2 of the semi-spherical cap top, and a lock core 3.1 is embedded in the lock body 1.1; the connecting position of the dustproof cover 1.2 and the lock body 1.1 is provided with a spring 1.3; the screw rod 2 is fixed with an inner wall 1.4 of a groove; a connecting shaft 3.3 is arranged on the back end of the lock core 3.1; a stopper 3.2 is sheathed on the connecting shaft 3.3; the stopper 3.2 passes through a fan-shaped hole 1.5 on the lock body 1.1. The utility model has the advantages of simple structure and convenient disassembly; besides, one anti-theft lock or a plurality of the anti-theft locks can be installed on tyres, the anti-theft effect is obvious, and the utility model is suitable for vehicles with various vehicle types.

Description

The tire anti-theft screw

Technical field

The utility model relates to hardware fitting, particularly a kind of tire anti-theft screw.

Background technique

China's automobile quantity increases sharply along with the growth of national economy.Vehicle parking is in unattended place, situation like that, the companion's and the problems such as " vehicle are stolen, vehicle tyre stolen " of coming reveals gradually, though the burglarproof lock of stepney has played certain anti-theft effect, the tire in using for automobile is had things stolen and is not had the effective counter measure so far, by the tire anti-theft screw after improving, neither influence attractive in appearance, do not influence normal safety traffic yet, played antitheft effect simultaneously, safeguarded numerous car owners' interests.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, convenient disassembly, the significant tire anti-theft screw of anti-theft effect for tire for vehicles.

For reaching the purpose of foregoing invention, the technological scheme that the utility model adopted is such: nut shape lock body is connected with screwed screw rod, the spherical crown of lock body semicircle has dust cover, and embedding has lock core, there is spring dust cover and lock body joint, dust cover can be at self-return under the spring action, the lock body the other end is the groove inwall, screw rod and groove inwall are fixed, lock core back of the body end is provided with coupling shaft, stopper is socketed on the coupling shaft, and stopper passes the fan shaped borehole on the lock body, behind key operated lock, stopper stretches along with the rotation of lock core under the drive of coupling shaft, the part of stretching out lock body when lock body is passed in stopper elongation is used for stopping that sleeve is inserted in screw and dismantles, otherwise stopper shortens and returns to that lock body is inner just can be inserted in screw with sleeve and to dismantle.

The advantage that the utlity model has is simple in structure, and convenient disassembly can be installed one or more these type of tire anti-theft screws on the tire, and anti-theft effect is remarkable, is fit to the vehicle of various vehicles.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As Fig. 1, shown in Fig. 2 a, the utility model nut shape lock body 1.1 is connected with screwed screw rod 2, the spherical crown of lock body 1.1 semicircles dust cover 1.2 arranged, and embedding has lock core 3.1 (the lock core internal structure is a prior art), dust cover 1.2 has spring 1.3 with lock body 1.1 joints, dust cover 1.2 can be under spring 1.3 effect self-return, lock body 1.1 the other ends are groove inwalls 1.4, screw rod 2 is fixing with groove inwall 1.4, lock core 3.1 back of the body ends are provided with coupling shaft 3.3, stopper 3.2 is socketed on the coupling shaft 3.3, and stopper 3.2 passes the fan shaped borehole 1.5 on the lock body 1.1, and is big outer little in fan shaped borehole 1.5 cross sections.

Shown in Fig. 3 a, Fig. 3 b, behind key operated lock, stopper 3.2 stretches along with the rotation of lock core 3.1 under the drive of coupling shaft 3.3, the part of stretching out lock body when lock body 1.1 is passed in stopper 3.2 elongations is used for stopping that sleeve is inserted in screw and dismantles, otherwise stopper 3.2 shortens and returns to that lock body 1.1 is inner just can be inserted in screw with sleeve and to dismantle.

Shown in Fig. 2 a, Fig. 2 b, lock body 1.1 and screw rod 2 be cast as one or not connecting screw rod 2 use separately as nut.

Shown in Fig. 2 a, it is cylindrical or triangular prism shaped that stopper 3.2 sections can be cuboid shape; Lock core 3.1 has one or more stopper 3.2.
