Abstract

The utility model discloses a mechanical theftproof lock to lock a gear lever of an automobile, which is composed of a centibar of the gear lever, a moving casing, a handle and a lock core, wherein the handle is fixed to the upper part of the centibar, and the lock core is arranged in the handle; the moving casing and the centibar of the gear lever are mutually sheathed, and the bottom of the moving casing is provided with a projection; the combining point of the moving casing and the lock core is provided with a matched lift mechanism. When the moving casing descends to the bottom, the projection on the casing is clamped with the case body of a gear case to restrict the movement of the gear lever and prevent the gear altering action. The theftproof lock of a gear lever of an automobile of the utility model with the whole lock device is combined has the structure that the entire lock is combined with the gear lever and has the advantages of compact structure, firm and reliable lock, and safe use because a larcener can hardly demount the lock from the outer part.

Description

Automobile gear shift lever anti-theft column lock

Technical field

The utility model relates to the anti-theft column lock of automotive use, relates in particular to a kind of mechanical antitheft lock from steam discharge car gear shift lever.

Background technology

Present auto shift automobile mechanical antitheft lock commonly used, its type mainly contains gear lock and handle lock.Fig. 1 is the structural representation of gear shift lever, gear case in the existing staged auto shift automobile.Gear lock commonly used comprises lock, dead bolt, and it is fixed on the automobile gearbox outer side edges with lock, cooperates external U-shape lock tongue, and the gear shift lever mortise lock is limited on the fixing gear.But must hole, shelve, adorn lock when this gear lock is installed, not only destroy body construction but also destroy decoration in the car, and fixing outstanding lock also occupies certain pair and takes advantage of the space; The car stealer can pass through to destroy the bolt of rear end plate of lock, thereby makes protection defending lock ineffective; External dead bolt easy-to-collection not when not locking is lost easily.

In addition, the protection defending lock of kind of fluid drive vehicle being arranged is shift button locking with the gear shift lever upper handle.It is installed on the gear shift lever handle, and structure comprises a lock housing and a latch hook, and lock-shell lining face and gear button correspondence position are provided with pit and insert for button.During use the latch hook mortise lock is gone in the snap close, can coat button, can't carry out the shift operation.But itself does not possess locking function the shift button, is difficult to prevent that the car stealer from stirring Shift lever by force and carrying out the shift operation.Also there is when not locking the shortcoming that is difficult to collect in same this lockset because lock housing and latch hook are two external accessories.

Summary of the invention

The utility model purpose is to overcome above shortcoming, provides a kind of sound construction, safe and reliable, easy to use automobile gear shift lever anti-theft column lock are installed in conjunction with gear shift lever.

Automobile gear shift lever anti-theft column lock of the present utility model is made up of gear shift lever center link, moving casing, handle, lock core, it is characterized in that: handle is fixedly connected on gear center link top, and lock core is installed in the handle; Moving casing and the mutual socket of gear center link, the moving casing bottom is provided with projection; The lifting mechanism that moving casing and lock core junction device match.Described lifting mechanism is meant the dipping and heaving that rotatablely moving of lock core is converted into moving casing.When moving casing dropped to the bottom, projection on the sleeve pipe and gear casing held out against, and the activity of restriction gear shift lever prevents the shift action; When moving casing rose to the top, projection on the sleeve pipe and gear casing got loose mutually, and gear shift lever is movable, realized the gear action.

As a kind of implementation wherein, described lifting mechanism comprises an intermeshing tooth bar and a gear, and tooth bar is inlaid in moving casing top, and gear is installed in the lock core end.The rotational lock core driven gear rotates, and wheel and rack is meshing with each other, control moving casing oscilaltion campaign.

As the another kind of way of realization of lifting mechanism, moving casing top sets firmly worm screw, lock core end installing worm gear, and described worm gear and worm screw are meshing with each other.Rotational lock core drives worm gear and rotates, control moving casing oscilaltion campaign.

Automobile gear shift lever anti-theft column lock of the present utility model is installed in lock core in the handle, moving casing and the mutual socket of gear center link, compact conformation; The projection of moving casing bottom and gear box body rigidity card limit make lockset more solid and reliable; Owing to whole lockset is made in conjunction with the structure of gear shift lever, the thief is not easy from the outside lockset to be dismantled, and uses safer relieved.It can be applicable to staged auto shift groove on the steam discharge car.

The specific embodiment

With reference to the accompanying drawings the utility model automobile gear shift lever anti-theft column lock is described further below.

Referring to Fig. 2, a kind of automobile gear shift lever anti-theft column lock of the present utility model, handle 1 is fixedly connected on gear center link 3 tops, and lock core 2 is inlaid in the handle, the anti-theft lock that lock core adopts smart steel casting to make, the other end of lock core is inserted with key 8; In the gear center link 3 socket moving casings 4, moving casing 4 is long than gear center link 3, and its bottom is provided with projection 5; The lifting mechanism that moving casing 4 and lock core 2 junction devices match.

Referring to Fig. 3, described lifting mechanism comprises, is inlaid in the tooth bar 6 on moving casing 4 tops, is installed in the gear 7 of lock core 2 ends, and tooth bar 6 and gear 7 are for being meshing with each other.Assembling is finished, and lockset and gear shift lever form integral structure.During use, the up-and-down movement of rotation of rotational lock core driven gear and tooth bar, control moving casing oscilaltion action.

Fig. 4 is the use reference diagram of the utility model on staged auto shift automobile, and with Fig. 1 contrast, lockset and gear shift lever are combined into one, and do not take interior space.During parking, driving handle 1 is pushed into the retaining P that stops with gear shift lever along gear groove 10, turns key 8.In conjunction with Fig. 3, lock core inner gear 7 rotates counterclockwise, and drives tooth bar 6 and moves downward, and makes movable sleeve 4 pipes drop to the bottom, and gear groove 10 holds out against in projection 5 on the sleeve pipe and the gear case 9, and the activity of restriction gear shift lever prevents the shift action.

Among Fig. 5, when unblanking, oppositely turn key 8.In conjunction with Fig. 3, lock core inner gear 7 clockwise rotates, and drives tooth bar 6 upward movements, makes movable sleeve 4 pipes rise to the top, and the edge of gear groove 10 breaks away from projection 5 on the sleeve pipe and the gear case 9, and gear shift lever is movable, realizes the shift action.
