Abstract

The utility model relates to an automotive tyre lock, which is composed of a lock body, a curved rod, a positioning disk, a locking rod and a driving mechanism in the lock body, wherein, the positioning disk is hinged on the curved rod to be used for buckling and contacting a rim; the locking rod is hinged with the lower part of the lock body, and is arranged in opposite direction with displacement with the positioning disk to be used for being buckled into the tyre on other side of a wheel; the locking rod is limited and locked by the driving mechanism, and thus the locking rod and the positioning disk clamp and fasten the wheel. The structure has the advantages of simple and convenient use, firm and simple locking, high universality, etc., and is particularly suitable for traffic management departments to manage common violated vehicles.

Description

The motor tire lock

The utility model relates to special-purpose Lock for automobile, particularly a kind of tyre lock that is used to tackle vehicles peccancy.

When the driver was absent from the scene, the traffic security personnel tackles general vehicles peccancy orthodox method two: one, directly vehicles peccancy is dragged away; The 2nd, copy down number-plate number button and penalize.Owing to vehicle dragged away will employ bigger human and material resources, spend very greatly, car owner's suggestion of being punished is also very big, for general violating the regulations, does not all adopt the means of trailer such as disorderly park, the overtime or parking of not paying the fees etc.But there is the time to copy down the number-plate number and can not plays actv. education and warning effect again.Therefore the traffic security personnel who has pins wheel with common big lock, and vehicle can not be started, and vehicle is detained so that the driver is educated and punishes.But present conventional lock is not well suited for the locking motor tire, and the corresponding spoon unlatching of lock, and is very inconvenient when the security personnel uses in a large number.

The purpose of this utility model is in order to overcome the deficiencies in the prior art part, to provide a kind of and can effectively lock tire, and easy to use, simple, the motor tire lock of highly versatile.

The purpose of this utility model is achieved by the following technical solution: the motor tire lock, include lock body, special feature is that a curved bar is arranged at the top of lock body, and dowel disc is equipped with in the end of curved bar, the lower hinge of lock body has securing rod, and dowel disc and securing rod cater in opposite directions but stagger in the position; Transmission device with rotation motion to linear is housed in the lock body, and the mouth of transmission device is as the positive stop end of securing rod around the hinge swing.

During use, securing rod is opened, dowel disc is adjacent to spoke, the wheel rim of wheel, the tire that inserts in the wheel opposite side and the junction of wheel rim are then blocked in the securing rod tip, rotation drive machine, until making its mouth withstand the securing rod rear end, securing rod can not be rotated, thereby securing rod with dowel disc with wheel obvolvent, locking, buckle dead.

It is simple, convenient that the utility model uses, and plays vehicles peccancy is carried out effectively and easy locking.

Below in conjunction with drawings and Examples the utility model is further elaborated.

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

Fig. 2 is the birds-eye view of Fig. 1.

Referring to Fig. 1 and Fig. 2, the lock body 1 of present embodiment is square, hollow, mounted inside has and is converted into straight-line transmission device with rotatablely moving, the top of lock body 1 is fixed with a curved bar 2, and curved bar 2 is outwards tortuous, leading section be one can be elastic sleeve 8, be movably hinged with dowel disc 3 on the sleeve 8, the size of dowel disc 3 and the diameter of automobile rim are makeed an appointment, and the outer studs with rubber 10, to prevent the spoke or the wheel rim of dowel disc 3 clashing and breaking wheels.The bottom of lock body 1 is opening-like, but is hinged with securing rod 4 by hinge 7, and the front end of securing rod 4 is convexly curved, and caters in opposite directions with dowel disc 3 but stagger mutually in the position; The rear portion of securing rod 4 then is blocked in the opening part 12 of lock body 1 bottom.Be snapped with an extension spring 11 between the middle part of securing rod 4 and the curved bar 2.Transmission device in the lock body 1 is the feed screw nut transmission device, and nut 5 is fixed in the lock body 1, and screw mandrel 6 passes curved bar 2, lock body 1 cooperates with nut 5, when clockwise rotating screw mandrel 6, screw mandrel 6 passes the opening part 12 of lock body 1, and screw mandrel 6 lower ends can prop up the rear portion of securing rod 4; When rotating counterclockwise screw mandrel 6, screw mandrel 6 oppositely passes lock body 1 and curved bar 2, and releasing is spacing to securing rod 4.For protection be convenient to rotary screw rod 6; spoon tube 9 is housed in the exit of lock body 1 top screw mandrel 6; and the eccentric shaft shape is processed in the upper end of screw mandrel 6, adopts special-purpose eccentric spoon to insert spoon tube 9, just can be easily rotary screw rod 6 (shown in thick arrow among Fig. 1) forward or backwards.

During use, overcome the pulling force of extension spring 11, securing rod 4 is outwards drawn back, dowel disc 3 is adjacent to the wheel rim of wheel one side, again securing rod 4 front ends are inserted the tire and the wheel rim junction of wheel opposite side, because dowel disc 3 is hinged with sleeve 8, sleeve 8 can do again certain distance before, the back is flexible, dowel disc 3 can be detained paste various dissimilar, the automotive wheel of size specification (shown in Fig. 1 long and two-short dash line), securing rod 4 then can block the handing-over position that inserts between cooresponding tire and the wheel rim, behind the location, screw mandrel 6 is screwed off, prop up the rear portion of securing rod 4 until the lower end of screw mandrel 6, make the securing rod 4 can not be again around hinge 7 swings, thereby with whole wheel obvolvent, button is dead, in case start automobile by force, tire is gone in the end of securing rod 4 just straight cutting, and the inner tube of a tyre is punctured, and wheel was lost efficacy.When unlocking, adopt unified eccentric spoon to insert spoon tube 9, anticlockwise motion, to move on the screw mandrel 6, releasing is spacing to securing rod 4 rear portions, and securing rod 4 can be rotated around hinge 7 again, drive securing rod 4 from wheel one layback, just dowel disc 3 can be withdrawed from wheel rim, extension spring 11 folds securing rod 4 automatically, realizes unblanking.

In sum, the utility model is simple in structure, easy to use, locks solid and reliablely, and highly versatile is the tyre lock of a kind of novelty, practicality, rich intention.
