Description

A kind of automobile anti-theft lock

Technical field

The utility model relates to a kind of automobile anti-theft lock, is a kind of by pinning the automobile anti-theft lock of power-transfer clutch specifically.

Background technology

At present, park in the open because many automobiles adopt, stolen phenomenon is very serious.The safety of automobile is parked becomes the problem that people pay special attention to.

Stolen in order to prevent automobile, released automobile anti-theft lock of all kinds on the market.Roughly can be summed up as two classes to them: electrical type alarming device for automobile anti-theft and mechanical anti-theft column lock.

Various electrical type alarming device for automobile anti-theft, the antitheft and warning effect in the time of can playing the stolen or malicious sabotage of automobile.But the characteristics of electronic safety lock are complex structure, cost height, easy flase alarm, the fault rate height.Its maintenance then needs special personnel, uses for undoubtedly general driver and makes troubles, so be difficult for popularizing.Therefore, people still are accustomed to using strong and reliable mechanical lockset to reach preventing that automobile is stolen.

Automobile mechanical class anti-theft column lock at present commonly used has and locks bearing circle and service brake simultaneously.One hooks automobile steering wheel during use, bearing circle is unloaded and does not rotate; Service brake is hooked in the other end, makes the cracksman can not step on service brake, reaches antitheft purpose.Perhaps only lock bearing circle, anti-theft column lock can not wide-angle freely rotate handwheel after vertically being installed on the handwheel of bearing circle.But because these locksets generally are installed in a bigger space, the thief can the very short time with instruments such as pressure clamp, hacksaw, master key cut off, sawed-off or join out.

In addition, the Lock for automobile ubiquity that uses is installed inconvenient characteristics in the market, and the prototype structure that some lockset more needs to destroy automobile reaches the installation purpose.

The utility model content

The purpose of this utility model is to provide that a kind of simple in structure, easy for installation, processing technology is simple, low cost of manufacture, automobile burglar lockset that theftproof performance is good, safe and reliable.It can adapt to dissimilar automotive uses.

This automobile anti-theft lock is made up of base, bindiny mechanism, lock body, two locks; Base one end flexibly connects by bindiny mechanism and lock body, and the other end has an aperture and cooperates with lock; Have on the described lock body and lock the bayonet socket that cooperates.Bindiny mechanism couples together base and lock body, forms a revolute pair or spherical pair, and two locks are installed on lock body.Reach the automobile burglar purpose by locking revolute pair and lock body bayonet socket.Wherein two shared identical keys also can use different keys.Bayonet socket can be " U " type, " V " type or other shapes.

When using the utility model, at first two locks are opened, pulled up key with key.Rotating base makes base and lock body roughly in alignment.This High Performance clutch-type anti-theft column lock is placed on pedal of clutch and the crossing below of clutch pedal link.Make the lock body bayonet socket over against clutch pedal link, base is close to the automobile bottom surface.Rotate revolute pair or spherical pair, make the lock body bayonet socket block pedal of clutch and clutch pedal link intersection area.At this moment, lock body is vertical with base.One of pin two locks respectively, or both, just can pin pedal of clutch, the device of putting into gear of automobile also just pins simultaneously.At this moment, because the power-transfer clutch of automobile and the device of putting into gear are unavailable, pin automobile in order to avoid stolen thereby reach.Remove this anti-theft column lock locking-in state, carry out according to the reverse order of locking.

Lock body described in the technique scheme and base can adopt integral pressure casting method, forging or the processing of other machine-tooled methods.

The utlity model has following characteristics:

(1) can pin the car clutch pedal and the device of putting into gear simultaneously, safe and reliable.

(2) make full use of the space, the working space when making the thief steal car is very limited, be difficult to sawed-off, cut off.Safety is good, automobile burglar performance height.

(3) this anti-joyride device major part adopts the integral pressure casting or forges, and simple structure, firm is installed easily, and cost is low, and is easy to use.Be fit to Quantity production simultaneously.

(4) adopt the alloy material manufacturing, quality is less relatively.When not using,, can adopt stored collapsed simultaneously because revolute pair is arranged, easy to carry.

(5) twin-lock design further strengthens safety.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail, but embodiment of the present utility model is not limited thereto.

Shown in Fig. 1,4, this automobile anti-theft lock mainly is made up of base 1, bindiny mechanism 2, lock body 3, lock 4, lock 5, and bindiny mechanism 2 couples together base 1 and lock body 3, forms a revolute pair, and lock 4 and lock 5 are installed on lock body 3.As shown in Figure 2, base 1 one ends flexibly connect with lock body 3 by bindiny mechanism 2, and the other end has an aperture and cooperates with lock 4; As shown in Figure 3, have on the lock body and lock 5 bayonet sockets that cooperate 6.During use, at first with key will lock 4 and lock 5 open, pull up key.Rotating base 1 makes base 1 and lock body 3 roughly in alignment.This automobile anti-theft lock is placed on pedal of clutch and the crossing below of clutch pedal link, makes lock body bayonet socket 6 over against clutch pedal link, base 1 is close to the automobile bottom surface.Rotate revolute pair or spherical pair, make lock body bayonet socket 6 block pedal of clutch and clutch pedal link intersection area.At this moment, lock body 3 is vertical with base 1.One of pin two locks respectively, or both, just can pin pedal of clutch, the device of putting into gear of automobile also just pins simultaneously.At this moment, because the power-transfer clutch of automobile and the device of putting into gear are unavailable, pin automobile in order to avoid stolen thereby reach.Remove state that this anti-theft column lock is lived, can carry out according to above-mentioned reverse order.Base 1 and lock body 3 adopt pressure die-casting or forging to form respectively, and rotating shaft 2 uses machinework to process.Lock body and base can adopt integral pressure casting method, forging or the processing of other machine-tooled methods.
