[utility model content]

In view of the problem that background technology exists, the technical problems to be solved in the utility model provides a kind of simple in structure, easy to operate, locking failure-free automobile anti-theft lock.

In order to solve the problems of the technologies described above, the utility model is realized in the following way: a kind of automobile anti-theft lock, include lock core, lock pipe and locking slide bar, it is characterized in that the locking slide bar is located in the lock pipe, described locking slide bar is provided with locking hole, the dead bolt of this locking hole and lock core is complementary, in the lock pipe, be provided with spring, this spring and the interlock of locking slide bar, the locking sleeve pipe is provided with mounting bracket, this spring is interlock like this in the locking slide bar: described locking slide bar has ducted body, and spring one end in the described lock pipe extend in the described ducted body, and contacts with the end of locking slide bar; Described lock pipe is provided with chute, is connected with a pull bar on the described locking slide bar.

When the utility model is used to lock the brake pedal of automobile, lock for convenience, be provided with fastener in the end of locking slide bar.

On the basis of technique scheme, in described locking slide bar, also be provided with a loop bar, described spring housing is on loop bar.

In the utility model, the locking slide bar slides in the lock pipe, and on the locking slide bar locking hole is set, and this locking hole is complementary in the dead bolt of lock core, adopts spring and locking slide bar linkage manner, can lock to the brake pedal and the clutch pedal of automobile; Easy to operate, simple in structure, be applicable to various vehicles, cost is low, will bring positive result of use to vast user vehicle.

The specific embodiment

Embodiment one:

With reference to Fig. 1, Fig. 2, Fig. 3, this automobile anti-theft lock includes lock core 4, lock pipe 6 and locking slide bar 1, in locking slide bar 1 is located at lock pipe 6, described locking slide bar 1 is provided with locking hole, the dead bolt 3 of this locking hole and lock core 4 is complementary, in the present embodiment, described locking hole has first locking hole 2 and second locking hole 8, lock pipe 6 is provided with a chute 10, on locking slide bar 1, be connected with pull bar 9, in lock pipe 6, be provided with spring 7, this

spring

7 and 1 interlock of locking slide bar, this spring 7 is to link like this with locking slide bar 1: described locking slide bar 1 has ducted body, and spring 7 one ends in the described lock pipe 6 extend in the described ducted body, and contact with the end of locking slide bar 1; This embodiment implements at automobile clutch pedal.When locking, turn key 5, rotational lock core 4 will break away from first locking hole 2 of dead bolt 3 from locking slide bar 1 of lock core 4, locking slide bar 1 is under the effect of spring 7, to lower slider, and withstand automobile clutch pedal, make autoclutch be in clutch state, and then turn key 5, the dead bolt 3 of lock core 4 is inserted in second locking hole 8, pull out key 5, just make automobile anti-theft lock be in locking state.When unblanking, rotational lock core 5 makes the dead bolt 3 of lock core 5 break away from second locking hole 8, pulling pull bar 9, overcome the elastic force of spring 7 after, make pull bar 9 rise along chute 10, the dead bolt 3 of lock core 4 is inserted in second locking hole 8, and automobile anti-theft lock is in unlocking condition, makes the automobile can normal driving.In order this automobile anti-theft lock to be installed in the operator's compartment of automobile, be provided with a ungulate mounting bracket 11 at the middle part of lock pipe 6.

Embodiment two:

With reference to Fig. 4, Fig. 5, Fig. 6, this embodiment implements at the braking automobile pedal.This embodiment also includes lock core 4, lock pipe 6 and locking slide bar 1, in locking slide bar 1 is located at lock pipe 6, described locking slide bar 1 is provided with locking hole 2, this locking hole 2 is complementary with the dead bolt 3 of lock core 4, in lock pipe 6, be provided with spring 7, this

spring

7 and 1 interlock of locking slide bar, described lock pipe 6 is provided with chute 10, is connected with a pull bar 9 on the described locking slide bar 1.This spring 7 is to link like this with locking slide bar 1: described locking slide bar 1 has ducted body, spring 7 one ends in the described lock pipe 6 extend in the described ducted body, and contact with the end of locking slide bar 1, in locking slide bar 1, also be provided with a loop bar 13, spring 7 is enclosed within this loop bar 13 mountains, has so more strengthened anti-theft effect.Be provided with a fastener 12 in the end of locking slide bar 1, be used to hook the braking automobile pedal, on lock pipe 6 mounting bracket 11 is installed, this mounting bracket 11 is mounted in automobile cab with respect to brake position, space, and anti-theft column lock is fixedly mounted on the car body.In the time will locking car, pulling pull bar 9, after overcoming spring 7 elastic force, locking slide bar 1 moves on chute 10, and when the locking hole on the locking slide bar 12 was aimed at the dead bolt 3 of lock core 4, dead bolt 3 sprang into locking hole 2 automatically, at this moment, the fastener 12 of locking slide bar 1 end just hooks the brake pedal of automobile, pulls out away key 5, just can reach the purpose of locking; When unblanking, as long as rotational lock core 4 makes locking hole 2 on the dead bolt 3 separating lock on-slip bars 1 on the lock core 4, the effect owing to spring 7 moves down locking slide bar 1, thereby makes fastener 12 break away from the braking automobile pedals, can remove, and makes the automobile normal driving.
