Abstract

The utility model relates to a super anti-theft safety lock for automobiles, which not only can be used for the theft prevention of automobiles but also can be used for protecting drivers. The utility model is composed of a lock head 1, lock frames 2, a lock tongue 3, a spring 4, a lock hook 5, a protective cover 6 and a U-shaped beam 7. The utility model is characterized in that the lock head adopts a super safe cylinder lock, nobody can unlock the lock without a key and a universal key is inefficient for the lock. Two lock beam jacks are arranged on the lock frames at both sides of the lock head. The U-shaped beam can not rotate after locked, which is favorable for protecting drivers. The protective cover is hung on the lock hook, and the thieves can not disassemble the pins of pedals. As a result, the utility model is a lock for automobiles, which is safe and convenient and has the functions of theft prevention and driver protection.

Description

Safety lock for automobile anti-theft and protecting driver

A kind of automobile burglar that can be used for is held concurrently for driver and the ruffian self-defence lockset of wrestling.

Automobile anti-theft lock partly is made up of tapered end, lock frame, latch hook, dead bolt, spring and hook-type lock bridge etc. usually, and is tight with colluding between throttle foot pedal and the steering wheel from upper and lower both direction with latch hook and hook-type lock bridge, stops the burglar to drive to commit theft.Yet they have two weak points:

One, the burglar can come off latch hook with the way of removing throttle foot pedal latch, loses anti-theft effect.

Two, can 360 ° of any rotations be unfavorable for that the driver is used as weapons for self-defense after the locking of hook-type lock bridge.

The utility model has overcome above-mentioned two deficiencies with very simple structure, reaches the effect that not only improves theftproof performance but also increase self-defence performance.

Accompanying drawing 1 is a front view of the present utility model.

Accompanying drawing 2 is lateral plans of the present utility model.

Accompanying drawing 3 is the schematic diagrames that are used for illustrating the utility model lock core and dead bolt correlation.

From attached Fig. 1 and 2 as seen, the utility model partly is made up of super safety cylinder lock 1, lock frame 2, dead bolt 3, spring 4, latch hook 5, guard shield 6 and U-shaped lock bridge 7 etc.

Lock frame 2 is actually by what two blank pipes were formed and falls L shaped structure, and an end of its lateral stub fuses at the A place with vertical long tube, and the other end of short tube has a B jack parallel with director's A pore.

It is vertical with transverse tube that tapered end (seeing patent ZL88204002.2 for details) is contained in the centre of lock frame transverse tube, and its lock core end 8(sees Fig. 2) stretch into the breach ι (see figure 3) of the dead bolt that is positioned at transverse tube central authorities.Because the lock core end makes and the asymmetric shape structure of lock core center line (for example shown in the dash area of Fig. 3), at ordinary times, spring is pressed to left with dead bolt, but is unlikelyly deviate from by lock core is spacing.And when lock core rotates, but contract behind its eccentric dissymmetrical structure control lock tongue.

A guard shield is arranged on the latch hook, and it is directly held and is fixedly connected on lock frame long tube below.

When using this lock, latch hook (band guard shield) is hooked the gas step, guard shield blocks the steady pin of step, stops the burglar to tear the pin crime open.Then, two pins of U-shaped lock bridge are blocked steering wheel and insert A, B two holes, until with step and steering wheel tension.Because dead bolt holds out against the pin of lock bridge all the time automatically under spring action, in case run into the groove hook on the pin, lock bridge is just bitten, and this action principle with general lockset is as good as.

Groove hook on the lock bridge is made in two inboards or an inboard of beam, and is multistage, and therefore lock is fit to various vehicles and selects for use apart from regulating.

When unblanking, open tapered end, with the key rotation, owing to the dissymmetrical structure of lock core, the drive dead bolt overcomes spring pressure and moves to right, and can pull out lock bridge and unblank like this.

Because the bipod of lock bridge can not change in A, the location, B two holes of lock frame, therefore makes the driver handy when using this lock and ruffian to fight with, and has strengthened self-defence ability.

In a word, owing to adopted super safe spring lock as tapered end of the present utility model, so nobody can open it without key, master key is invalid, add reasonable structural design, it is not only safe and reliable but also easy to use that this lock is become, and can be for the desirable lockset of the self-defence automobile burglar of driver.

Claims

A kind ofly not only can be used for automobile burglar but also can be used for self-defence super insurance theftproof lock, form by tapered end 1, lock frame 2, dead bolt 3, spring 4, latch hook 5, guard shield 6 and U-shaped beam 7, it is characterized in that tapered end has adopted super safe spring lock, flexible lock core 8 ends of control dead bolt are made into the asymmetric shape of circumference; The lock frame has two jacks, makes the U-shaped beam become not turntable after locking; Hang with a guard shield on the latch hook.
