Abstract

The utility model mainly relates to a mechanical anti-stealing lock for a vehicle, which comprises an upper fixing body, a lower fixing body, and a lock core. The utility model is characterized in that a braking body and the surface of the upper fixing body form a rolling connection; the lock core is arranged on the braking body; a gear fixedly arranged on the tail end of the lock core is engaged with racks which are fixedly arranged in the braking body. The utility model can prevent the damage of smashing, prying, etc., and thereby, the possibility that anti-stealing performance is lost due to being cut off can be fundamentally eliminated, and the utility model can effectively prevent the vehicle from being unlocked by a master key, and furthermore, an alarm device can be prevented from losing the effect due to being damaging.

Description

Anti-theft device for vehicle

The utility model belongs to vehicle theftproof locks such as bicycle, motorcycle, automobile, relates generally to mechanical antitheft lock.

The anti-theft device for vehicle of prior art can be divided into two classes, and a class is a mechanical brake device, i.e. lockset; Another kind of is electric anti-thief device, i.e. alarm.For lockset, can be divided into three kinds again, a kind of is electronic lock, promptly pins priming supply; This device easily electric wire is pulled down and ineffective or changing-over to standby electronic lock and open.Two kinds is the direction lock, even direction can't change; This device generally is built in handlebar inside, but the robber utilizes handlebar or the producible significant shear moment of torsion of large size spanner, only just can be very easy with its device destruction with several seconds, thus make it make antitheft effect.Three kinds is the wheel lock, even its wheel can not rotate; Chain type, steel rod formula, steel wire rope type or the like are arranged, and all are through the wheel both sides, combine the braking that constitutes wheel with vehicle frame, this kind lock run through part, easily used the lever bolt clipper to cut off in moment easily by the robber.Outside its binding site all was exposed to, it is anti-pounded, anti-sled, shock resistance are relatively poor, and mostly its lock core be the common spring lock core, and a spoon groove laterally can connect, and the marble spring compressible space is bigger, can not prevent the unlatching of master key, and lose anti-theft feature.For alarm; be divided into again mobile, vibration touches, several near reporting to the police automatically etc.; this type of device all is installed on a certain position of car; lack reliable external protector; easily go to pot; and existing lock can be destroyed at short notice and be lost anti-theft feature, has also limited the performance of autoalarm anti-theft feature.

The purpose of this utility model provides and a kind ofly anti-cuts, pick-proof, anti-ly pound, anti-theft device for vehicle that preventing universal key is opened.

Another purpose of the present utility model provide a kind of prevent warning device destroyed and the forfeiture anti-theft feature anti-theft device for vehicle.

The utility model comprises fixed body and following fixed body, and lock core, it is characterized in that the formation of brake body and last fixed body surface is rotationally connected, and lock core is installed on the brake body, is fixed on the gear and the tooth bar engagement that is fixed in the brake body of lock core end.

The shaped form of the utility model lock core teeth groove for not connecting.The middle part of brake body is provided with groove, and alarm is placed in the groove.Brake body is that end face is the cylindrical part of arc, contacts with the surface of last fixed body, forms being rotationally connected around last fixed body surface.

Armor facing structure of the present utility model can effectively be prevented destructions such as locking apparatus is pounded, quilt is prized; The moving structure of its single shoe brake system fundamentally eliminated cut off and lose theftproof performance may, its preventing universal key structure can effectively prevent by unlocked by universal key; Autoalarm is placed in the groove at brake body middle part, can prevents effectively that warning device is destroyed and forfeiture effect and lock are destroyed for a long time and car is handled upside down or hauls and steal.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the B-B sectional view of Fig. 1;

Fig. 4 is the lock core structure schematic diagram of Fig. 1;

Fig. 5 is the C-C sectional view of Fig. 4;

Fig. 6 is lock core, gear, tooth bar connection schematic diagram;

Fig. 7 is the installation site schematic diagram of the utility model embodiment;

Among the figure, following fixed body 1 is installed on the wheel 19 inboard horizontal supports 18, with slotted round head screw it is combined with last fixed body 2, with fluting long cylinder screw itself and vehicle frame are fixed again, when device is enabled, brake body 3 can be done 90 ° of rotations (anglec of rotation can be selected) around standing part in 0～180 °, thereby wheel 19 is played braking action.During this state, brake body contains binding site and hold-down screw etc. in it as plate armour, forms the protection structure.Connecting by separately connected body 9, connected body 10 of brake body 3 and last fixed body 2 moved in the other side's rail groove 6, rail groove 8 and carried out.Each connected body enters respective carter from two of respective carter during assembling, with screw track is blocked then, makes it can not get back to initial position, thereby can't throw off again.Dynamic resistance keyway 11 one vertical with two tracks, that connect is arranged in the brake body 3, the built-in dynamic resistance key bar 7 that connects by gear 16 and tooth bar 13 with lock core 4, when device is enabled, promote brake body 3 rotations, its connected body 10 moves to dynamic resistance key bar 7 places in orbit, clash into its inclined-plane, it is moved upward, and then connected body 9,10 is passed through.Then, dynamic resistance key bar 7 with the track blocking-up, thereby can't reply brake body 3 at the effect of its back-moving spring 12 home position next time.Be in initiate mode this moment, and promptly lockset is in closed condition.Lock core 4 terminal fixed gears 16 are with tooth bar 13 engagements on the dynamic resistance key bar 7.When opening lockset, by key rotation lock core 4, it is up that gear 16 drives dynamic resistance key bar 7 by tooth bar 13, thereby track is open-minded, brake body 3 returns to the home position under the effect of back-moving spring 12 at this moment, is opening.

Spoon groove 17 in the lock core 4 of the present utility model adopt can limit lateral move can not through structure, and limited the compression stroke of pellet shot from a slingshot 14, spring 15, make master key pellet shot from a slingshot can not be released lock core.Master key can't be opened and ineffective.

Give in the brake body of the present utility model and stay groove 5, autoalarm can be installed on this, thereby protected by it, in order to avoid destroyed.
