Description

The motor-tricycle anti-joyride device

Technical field

The utility model relates to the anti-theft device for vehicle field, especially relates to a kind of novel structure that is used for motor-tricycle, the motor-tricycle anti-joyride device of good anti-theft effect.

Background technology

Three-wheel vehicle is as a kind of flexible transport facility, oneself is adopted widely, but owing to there is not suitable lockset, the lock car is a difficult problem all the time, past people adopts iron chains or steel wire penetrating wheel to lock car mostly, but extremely inconvenient, iron chains can not be locked two driving wheels in back too in short-term simultaneously, and iron chains is long then very heavy again, when riding, the iron chains band also is in the way onboard very much.

The three-wheel vehicle of selling on the market is not all installed anti-theft column lock, and people are stolen for preventing three-wheel vehicle, generally adopts steel rope or iron chains to add padlock and pins wheel.Though its method has convenient feasible advantage, also has following shortcoming simultaneously: the one, its steel rope is easily cut off or padlock is smashed and car stolen cause economic loss; The 2nd, steel rope or iron chains are too stupid.Inconvenience is carried and the cost height, poor reliability etc.Along with society and science and technology development.People thirst for appearing on the market of a kind of agricultural tricycle anti-theft column lock, can prevent effectively that three-wheel vehicle is stolen.

Now, the kind that is used for the lock on the three-wheel vehicle is a lot, also each is variant for its structure, what generally adopt all is directly to fasten mortise lock with a bolt or latch, two kinds of single door bolt and pair door bolts is arranged, when this lock is installed on the front fork, it is not too convenient to install, especially also have shock mitigation system etc. on the front fork of three-wheel vehicle, and will bend over just can open when opening lock, use also inconvenient.Now also useful chain lock or steel rope lock, this lock will pierce into wheel or vehicle frame with chain or steel cable, and then pinning, and after opening lock, also lock will be tidied away, like this will the duplication of labour, use very inconvenient, time-consuming again.

And present domestic motorcycle industry does not also occur taking the method for welding anti-joyride device on back axle to reach the motor-tricycle of antitheft purpose.

The utility model content

In view of this, the purpose of this utility model is to provide a kind of novel structure, and by the locking trailing wheel, cutting off the electricity supply simultaneously reaches antitheft purpose motor-tricycle anti-joyride device.

The technical solution of the utility model realizes with following method:

The motor-tricycle anti-joyride device, comprise vehicle frame, be installed in the back axle on the vehicle frame, be installed in the trailing wheel at back axle two ends, wherein, vehicle frame or back axle are provided with the anti-theft column lock sheath, are provided with the anti-theft column lock cut-off switch in the anti-theft column lock sheath, the anti-theft column lock cut-off switch is connected with the electronic ignition device of driving engine, is plugged with anti-theft lock in the sheath hole of anti-theft column lock sheath.

The sheath hole inwall of described anti-theft column lock sheath is provided with positive stop strip.

Described anti-theft column lock sheath becomes the angle bar shape.

Described anti-theft column lock cut-off switch is a push switch.

The beneficial effects of the utility model are:

Compare with traditional anti-theft column lock, this motor-tricycle anti-joyride device stops that by lock core trailing wheel rotates and the double anti-theft means of combustion cutoff electronic ignition device, and anti-theft effect is good, is difficult for stolen; Anti-joyride device and back axle welding one are solid and reliable, and difficult quilt is damaged.

Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following specification sheets, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model running condition scheme drawing.

The specific embodiment

Below in conjunction with drawings and Examples the technical solution of the utility model is described further:

As Fig. 1 and Fig. 2 as can be seen, this motor-tricycle anti-joyride device, comprise vehicle frame 1, be installed in the back axle 2 on the vehicle frame 1, be installed in the trailing wheel 3 at back axle 2 two ends respectively, near rear flank wheel welded and installed one anti-theft column lock sheath 5 is arranged on the back axle 2,5 one-tenth angle bar shapes of anti-theft column lock sheath, the turning is 90 °, be installed with the anti-theft column lock cut-off switch 4 of a push type in the anti-theft column lock sheath 5 over against sheath hole 9, anti-theft column lock cut-off switch 4 is connected with Motronic control maps ignition device 7 by lead, has the effect of starter power switch, the sheath hole 9 inwall symmetries of anti-theft column lock sheath 5 are installed with positive stop strip 8, are plugged with an anti-theft lock 6 in the sheath hole 9 of anti-theft column lock sheath 5.

Principle of work:

When motor bike is placed in Parking, anti-theft lock 6 is inserted in the sheath hole 9 of anti-theft column lock sheath 5 by the trailing wheel spoke, half-twist is stuck on the positive stop strip 8 locked trailing wheel; In locked trailing wheel, anti-theft lock 6 presses and Motronic control maps ignition device 7 bonded assembly anti-theft column lock cut-off switchs 4, and anti-theft column lock cut-off switch 4 cut offs make the driving engine can't ignition start; Locked and the down circuitry two aspects realization motorcycle anti-theft by machinery.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
