Abstract

The utility model provides an anti-theft device of a disc locking type for a vehicle, which comprises a locking end of a steering wheel and a limited rod, wherein the locking end comprises a lock tongue and a rotating cylinder, the lock tongue is arranged at the inner side of the rotating cylinder, and a clamp opening on the rotating cylinder and a buckle tongue on the lock tongue form a locking device of the steering wheel. The lock tongue is fixed on the limited rod, the rotating cylinder can be rotated corresponding to the lock tongue along the shaft center of the limited rod, and a ratchet wheel locking and controlling device is arranged between the lock tongue and the rotating cylinder. When the anti-theft device is locked, the rotating cylinder only can be in clockwise rotation, and the rotating cylinder can be freely rotated when the anti-theft device is unlocked. When the utility model is used, the anti-theft device forms a baseball bar shape, the purpose of locking a disc can be realized by rotating the limited rod after the steering wheel is sheathed on, and the operation with one hand is convenient.

Description

A kind of car alarm

The utility model relates to a kind of alarms and security systems for automobiles.

Along with the continuous development of society, car opertion is more and more general, but the antitheft problem of automobile is still a difficult problem of being stranded automotive use.The use of going on the market of various automobile anti-theft locks, mechanical anti-theft lock mainly contains lock gear-type and lock collar formula, present lock collar formula anti-theft column lock, having than the anti-theft column lock of lock gear-type need not hard-wired characteristic, but still have heavy, inconvenient one-handed performance and unblank after deficiency such as be not easy to shelve.

The purpose of this utility model is to provide a kind of comparatively light and handy and handled easily, puts and put lock collar formula automobile anti-theft lock easily, deficiency such as overcome heaviness, the inconvenient one-handed performance that the lock collar formula automobile anti-theft lock that generally uses at present exists and be not easy to shelve, and enrich the style of mechanical type automobile anti-theft lock.

For achieving the above object, the utility model adopts the basic structure of common lock disc type car alarm, structurally include keyed end that can be fixed on the vehicle steering and the position-limited lever that is arranged on keyed end one end, keyed end and position-limited lever are that coaxial softball is bar-shaped, and keyed end includes dead bolt and rotating cylinder; Dead bolt is arranged on the inboard of rotating cylinder, the rear end of dead bolt connects and radially is fixed on the position-limited lever, can rotate with position-limited lever, and the front end of dead bolt is provided with the mount pad of rotating cylinder, the middle part of dead bolt is provided with a button tongue curved with respect to the axle center, and the radian of button tongue and the radian of rotating cylinder inwall adapt; The rear end of rotating cylinder is connected on the position-limited lever, and the front end of rotating cylinder is installed on the mount pad of dead bolt front end, and rotating cylinder can rotate along the axle center of position-limited lever and with respect to dead bolt; Between the mount pad of dead bolt front end and rotating cylinder, be provided with an escapement, escapement is that the mount pad of dead bolt front end is provided with a handle ratchet wheel, the front end of rotating cylinder is provided with the lock core that matches with handle ratchet wheel, and lock core is provided with can be by the ratchet check device of key control; Lock-bit is a default setting, the work of ratchet non-return, and rotating cylinder can only clockwise rotate along the axis of position-limited lever; Ratchet non-return cancellation when unblanking, rotating cylinder can freely rotate along the axis of position-limited lever; Rotating cylinder is provided with bayonet socket, and bayonet socket cooperates the blocking device that constitutes bearing circle with button tongue on the dead bolt.Principle of work of the present utility model is: under normal condition, and the work of ratchet check device, the rotating cylinder of this moment can only clockwise rotate along the axis of position-limited lever; When pinning bearing circle, the bayonet socket of rotating cylinder can be enclosed within on the bearing circle, and the coil that makes bearing circle is stuck on the button tongue of dead bolt, clockwise rotate rotating cylinder or position-limited lever, the button tongue that can make the bayonet socket of rotating cylinder and dead bolt is with the bearing circle fastening, Car Burglar Alarm is installed on the bearing circle, and position-limited lever limits the rotation of bearing circle and reaches antitheft purpose; When unblanking, the cancellation of ratchet check device, rotating cylinder can rotate counterclockwise, and the bayonet socket of rotating cylinder unclamps the restriction to bearing circle, and Car Burglar Alarm can break away from bearing circle and release.

Use the utility model, it is bar-shaped that Car Burglar Alarm is softball, and the lines flow smoothly for light and handy and outward appearance, convenient singlehanded the use, and it is also comparatively convenient that the anti-theft column lock after unblanking is placed.

Fig. 1 is a structure principle chart of the present utility model;

Fig. 2 is a schematic appearance of the present utility model.

Below in conjunction with accompanying drawing structural principle of the present utility model is described in further detail.
