Description

A kind of tricycle anti-theft lock device

The utility model relates to a kind of anti-theft lock device, especially a kind of tricycle anti-theft lock device.

In the prior art, be not used in the special lockset of three-wheel vehicle locking, chain lock is often used in the locking of three-wheel vehicle, perhaps passes vehicle wheel spoke with iron chains, again with the two ends of iron chains tapered end interlocking.Above-mentioned chain lock or iron chains be because its flexible and longly very easily be placed in the cutting edge of tool for destroying and cut off, so the three-wheel vehicle that locks with this class lockset is stolen often.Lock is with the three-wheel vehicle of chain lock, and the robber uses general pliers just can cut off chain lock within several seconds car is stolen; Even on three-wheel vehicle, the robber uses afterburning pliers also can easily it all to be destroyed and car be stolen four, five shackle locks.

Three-wheel vehicle easily stolen basic reason is that present to substitute lockset very easy to be destroyed, and the crime molecule can destroy lockset in the extremely short time.Therefore, reduce the stolen of three-wheel vehicle, one of measure wherein is exactly a damage resistance of strengthening the three-wheel vehicle lockset.

The purpose of this utility model is to improve the deficiencies in the prior art, provides a kind of damage resistance strong and easy to use, simple in structure, the tricycle anti-theft lock device that is easy to make.

The utility model is achieved in that anti-theft lock device includes the base plate and the lock bridge of rigidity, described lock bridge inflection, and its two ends all link with described base plate, wherein constitute the removable draw bail that can lock connection by a tapered end between an end and the base plate; The other end of lock bridge passes the hole of being offered on the described base plate and fixes when aforementioned end lock is coupled on the base plate.

The cross sectional shape of described lock bridge, size and the material selected for use thereof are so that lock bridge can be resisted the fail in shear of portable pliers or afterburning pliers is bottom line.

When using this anti-theft lock device, described base plate is welded on the steel pipe chassis frame of three-wheel vehicle, during the locking three-wheel vehicle one end of described lock bridge passed vehicle wheel spoke and insert on the base plate in institute's perforate, meanwhile the other end of lock bridge and base plate pass through the tapered end interlocking.

In order to make existing three-wheel vehicle this anti-theft lock device of fit on easily, described base plate not necessarily will be welded on tricycle frame's beam, and base plate is connected with a clamp, that is: clamp and base plate are provided with point of attachment in the corresponding section.When this locking device was installed, clamp and base plate were sandwiched in three-wheel vehicle steel pipe chassis frame both sides and connect firmly on vehicle frame with point of attachment.Point of attachment between clamp and the base plate can be made up of the some holes offered in the corresponding position of clamp and base plate and the bolt that cooperates with it.

Like this three-wheel vehicle that locking is good since this lockset do not resemble chain lock or iron chains length have flexibility again, can put it into the cutting edge place of tool for destroying easily, and not easy-to-use portable pliers or afterburning pliers are cut off.This lock bridge is difficult for destroyedly in a short period of time falling the therefore generation that can prevent to steal the car case effectively.

For the ease of using, can be fixed on tapered end on the base plate, opening the trouble of losing and avoiding depositing that can prevent tapered end when this locking device uses three-wheel vehicle like this.

The placement of lock bridge when unblanking to use three-wheel vehicle for convenience, can extend on the base plate socket aperture and/or with the joining clamp of base plate on establish a socket aperture for inserting lock bridge, the distance between described two socket apertures should be complementary with the vertical distance at lock bridge two ends.

The tricycle anti-theft lock apparatus structure that the utility model provides is very simple, but its damage resistance improves, robber's desire is stolen the three-wheel vehicle with the locking of this anti-theft lock device, block lock bridge, because of the very near pliers of itself and wheel distance is inserted not go down, and not easy-to-use portable pliers or afterburning pliers are cut off, if block lock bridge with saw, meeting is big because of sound, time length is easy to be found.Characteristics that are different from the padlock of general beam with lock in addition of this anti-theft lock device are to have only an end lock bridge sealed, and the other end just inserts in the hole on the base plate, and the existing padlock of this texture ratio saves a bigger lock body, and is simple in structure, be easy to install on three-wheel vehicle, cost is also lower.

The lockset that the utility model provides also can be used for the usefulness that storehouse etc. is located the locking of door, uses this lockset also to belong to protection domain of the present utility model in these places.

The utility model is described in further detail below by drawings and Examples.

The part sectional view of bowing of Fig. 2: Fig. 1.

Embodiment:

As shown in Figure 1, 2, base plate 1 and two bolts 3 of clamp 2 usefulness are fixed on the three-wheel vehicle steel pipe chassis frame 4, the spoke that one end 5-1 of lock bridge 5 passes wheel 6 is inserted among the hole 1-1 that is offered on the base plate 1, its other end 5-2 interlocking is on the tapered end 7 that is fixed on the base plate 1 simultaneously, and tapered end 7 can be opened by key 8.When opening this lock, the two ends of lock bridge 5 can be inserted in tapered end on the base plate respectively and prolong on the clamp 2 that among the hole 1-2 that opens in the place and prolong among the hole 2-1 that opens in the place.Tapered end 7 on the base plate 1 preferably leans against the vertical beam 4-1 of steel pipe chassis frame 4 so that the location.
