The utility model is characterized in that a built-in lock is arranged at one position on the tyre cap; the built-in lock comprises two or more lock tongues; lock seats corresponding to the lock tongues are arranged on the wheel hub; the lock tongues of the built-in lock can be rotated to extend out to be clamped into the lock seats. The utility model uses the built-in lock to lock a tyre on the wheel hub to obtain the goal of preventing the tyre from being stolen or loosen to be lost.

Description

The tire lid

The utility model relates to a kind of tire lid, the especially tire of self-propelled vehicle lid.

At present, the tire of self-propelled vehicle lid mostly is stamped to form with metal or alloy, firmly is pressed in the wheel hub side of tire, plays dustproof and decoration function.But because there is not captive joint, often pull down again so that give inflation of tire, inspection etc., thus loosening easily, cause losing, not only influence attractive in appearance but also sink money.Even more serious is: do not have tire lid or tire lid just can be removed easily and make outside a tire and an axle bonded assembly hold-doun nut be exposed to, the thief is easy to tire is stolen.This phenomenon is quite general.

The purpose of this utility model just provides and a kind ofly prevents that tire is stolen, has the tire lid that decoration function can not come off again.

The purpose of this utility model is achieved in that it comprises tire lid and wheel hub, this tire covers and is provided with a built-in lock, this built-in lock contains two or more dead bolts, and wheel hub is provided with the lock of corresponding dead bolt, and the dead bolt of built-in lock can be rotated to stretch out and snap in the lock; During use the tire lid is pressed in the tire side, insert rotation in the lockhole of built-in lock with key and dead bolt stretched out enter in the lock, and it is locked on the wheel hub, because of the tire lid keeps off tire and axle bonded assembly nut in lid, the thief twists less than nut, thereby reach theft-proof purpose, again because of the tire lid is locked on wheel hub, so can not lose by loose or dislocation.

The utility model is compared with existing tire lid, has the following advantages:

1, can prevent that tire is stolen.

2, the tire lid can not come off.

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

Fig. 1 is a tire lid rear view (RV) of the present utility model.

Fig. 2 is along A-A line cutaway view among Fig. 1.

Shown in Fig. 1,2, the utility model includes tire lid and wheel hub, and the home position that covers in tire is fixed with a built-in lock 5, and this built-in lock is provided with two

dead bolts

1,2, be on the same diameter of tire lid, the position of corresponding

dead bolt

1,2 is respectively equipped with two grooves 3,4 (lock) on the wheel hub.Firmly the tire lid is buckled in the tire side, turns key,

dead bolt

1,2 just is stuck in the

groove

3,4 on the wheel hub, and like this, the tire lid just can not come off.And for example shown in Figure 2, the groove 3 on the wheel hub can limit the action radius (same groove 4 can limit the action radius of dead bolt 2) of dead bolt 1, so the tire lid can not drop out from wheel hub because of rotation.During unlatching, as shown in Figure 1, twist with key one,

dead bolt

1,2 just withdraws in

groove

3,4 respectively, pulls outward or prize the tire lid with screwdriver to get final product.Because of tire lid periphery and wheel hub coincide tightly, and the tire lid blocked a tire and an axle bonded assembly nut, and the thief twists less than nut, has therefore reached the purpose that prevents that tire from being stolen.
