Description

The gas stop anti-theft lock

The utility model belongs to the lock technology field, relates to a kind of alarms and security systems for automobiles.

Known to the applicant, apply for the various automobile anti-theft locks of having of Chinese patent at present.They wherein have plenty of and pin vehicle steering, have plenty of and pin gear lever, have plenty of to snap onto on steering wheel and the brake pedal (or clutch pedal).But do not see as yet lock is set on gas pedal.

The purpose of this utility model is to design a kind of like this lock.It can fix gas pedal, makes it to move.Motor can't fuel feeding, and automobile can't start, thereby prevents that automobile is stolen.

The utility model is design like this: the gas stop anti-theft lock, it has hole by the locking closure 5 and the centre that have snap close 6, the lock housing 1 of spring bolt 8 and gas pedal 4 three parts that the corresponding position has hole are housed in transfer in the hole to be formed, during locking, locking closure 5 inserts in the gas pedal from the top down, lock housing 1 is filled in from the gas pedal below, the three is chained together by snap close 6, notch on the snap close 6 is blocked by spring bolt 8 at this moment, in the middle of gas pedal is locked in, can't move, thereby by stop.

The flange of broad is all arranged on 5 three directions of locking closure, and it all covers to close and firm gas pedal 4, lock housing 1 and binding site each other, and the three forms one, and very difficult quilt is prized or smashed.

Device has cylindrical billiard lock core and middle locking bolt in the locking closure 1, and private key 14 just can make the rotation of cylindrical billiard lock core, and locking bolt in the middle of the operation promotes spring bolt 8 and retreats.Decontrol the snap close 6 on the locking closure 5, lock is opened; Pull out locking closure 5, take lock housing 1 away, gas pedal 4 state that affranchises.

The afterbody of spring bolt 8 is equipped with holddown spring 9, and an insurance bar 17 is from top to bottom arranged between holddown spring 9 right-hand members and the lead sealing 10, and there is lead sealing 16 its upper end.Lead sealing was destroyed, and insurance bar 17 is still being protected spring 9 and spring bolt 8, and the external world can't change the position and the state of spring bolt 8.

The globality that the utility model has the advantages that lock is strong, and is airtight firm.When no key, lock can not be disassembled, and also can not pried open or be smashed, and has avoided automobile stolen effectively.

Below in conjunction with accompanying drawing structure of the present utility model, operating principle are further described.

Fig. 1 is a structural principle schematic diagram of the present utility model.

1. lock housing 2. accelerator rods 3. pins 4. gas pedals 5. locking closures 6. snap closes 7. are locked 8. spring bolts, 9 springs

Fig. 2 is a locking bolt controlling organization schematic diagram in the lock housing.

8. bars are insured in 16. lead sealings 17. of locking bolt 14. keys 15. cylindrical billiard lock cores in the middle of spring bolt 9. springs 10. lead sealings 11. lead sealings 12. springs 13.

Referring to Fig. 1, the gas pedal 4 on the automobile, left end is connecting accelerator rod 2 by pin 3, and right-hand member is hinged by pin 7 and driver's cabin base.Open a through hole in the middle of the gas pedal 4.All there is the flange of broad on three limits of locking closure 5, and snap close 6 lower ends that are connected as a single entity with it have notch.

Lock housing 1 left end has the U-shaped cavity, and right-hand member has a step, accelerator rod 2 and pin 7 under holding respectively on the gas pedal 4.Have hole in the middle of the lock housing 1, the right-hand spring 9 that is provided with spring bolt 8 and plays pressuring action at hole middle part.During locking, lock housing 1 is filled in the below of gas pedal 4, aim at the hole in the middle of the two, accelerator rod 2, pin 7 just in time snap in the lock housing 1.Buckle locking closure 5, the through hole that snap close 6 passes gas pedal 4 enters the hole of lock housing 1.After the lower end of snap close 6 knocked the inclined-plane of spring bolt 8, spring bolt 8 retreated; Snap close 6 continues to pierce into, and when notch arrived a certain position, spring bolt 8 sticked into notch under the effect of spring 9, and locking closure 5 fixed-site can't be advanced and retreat.At this moment, locking closure 5, gas pedal 4, lock housing 1 three are adjacent to mutually.Locking closure 5 can't take off, and in the middle of gas pedal 4 is clamped at, can't move.Motor just can not refuel, and automobile can't start.Because all there is the flange of broad on locking closure 5 three limits, it can both be firm with lock housing 1, gas pedal 4 and three's bound fraction be enclosed among the locking closure, therefore extraneously can't find the weak link of prying open or smashing, it can't be taken apart, thereby reach the purpose of automobile burglar.

Referring to Fig. 2, the left end of spring bolt 8 has the inclined-plane, and during locking, the inclined-plane sticks into the notch of snap close 6.Its right-hand member afterbody has spring 9 to compress.Between spring 9 right-hand members and the lead sealing 10, have one to insert the insurance bar 17 that gets off from the top, there is lead sealing 16 its upper end.Lead sealing was disassembled, and insurance bar 17 is still intercepting spring 9 and spring bolt 8, makes the external world can't change the position and the state of spring bolt 8, just can't open the lock of firmly closing.

Between spring bolt 8 and cylindrical billiard lock core 15, locking bolt 13 and spring 12 in the middle of being equipped with.Among key 14 inserts cylindrical billiard lock core 15, make its rotation, lock core 15 shape of threads ends have just promoted spring bolt 8 and have moved backward, i.e. and snap close 6 is decontroled in locking bolt withdrawal, and lock is opened.Just can take locking closure 5, lock housing 1 away this moment, gas pedal 4 state that affranchises.Automobile just can start.The cylindrical billiard lock core that circles round is taken key 14 away, under the effect of spring 12, and middle locking bolt 13 homings.Under the effect of spring 9, spring bolt 8 homings, locking bolt pass portion stretches into the hole of lock housing 1, is in the lock state for the treatment of.

Same principle and scheme can be applied to gas pedal and control on the miscellaneous equipment of engine oil path, on forklift or other motor vehicles.
