ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a locking device for vehicle, especially to a burglarproof locking device for handle and airbag of vehicle.
BACKGROUND OF THE INVENTION
FIG. 1A
shows the perspective view of a conventional burglarproof locking device for handle of vehicle. The burglarproof locking device comprises a long sleeve
10
a
, a short sleeve
11
a
and a connection tube
12
a
therein. One end of the tube
12
a
is inserted into a hollow end of the long sleeve
10
a
. The long sleeve
10
a
has a U-shape hook
13
a
and an H-shape hook
14
a
, and the short sleeve
11
a
has an H-shape hook
15
a
. The H-shape hook
14
a
and the H-shape hook
15
a
are arranged at the same side and aligned in a line. A key unit
16
is arranged beside the U-shape hook
13
a
and controls the movement of a sliding block (not shown) engaged within the connection tube
12
a
such that the position of the connection tube
12
a
can be adjusted and the short sleeve
11
a
can be rotated to cover the handle, clutch and brake pedal of the vehicle.
However, the airbag of the vehicle is generally expensive equipment and can not be locked by the conventional burglarproof locking device for handle of vehicle. The long sleeve
10
a
and the short sleeve
11
a
of the conventional burglarproof locking device are slim tubular shape, therefore, the conventional burglarproof locking device can not provide sufficient protection for the airbag. The burglar can easily take away the airbag of the vehicle even thought the conventional burglarproof locking device is locked upon the handle.
Moreover, the U-shape hook and the H-shape hook of the conventional burglarproof locking device are made of cylindrical or sheet-like material. The U-shape hook and the H-shape hook can not provide sufficient clamping force for the handle even ought the conventional burglarproof locking device is locked on the handle.
It is an object of the present invention to provide a burglarproof locking device for handle and airbag of vehicle, which has larger covering area such that the burglarproof locking device can also cover the airbag when being mounted on the handle.
It is another object of the present invention to provide a burglarproof locking device for handle and airbag of vehicle, which has L-shape hook with arc shape surface corresponding to the rounded handle, whereby the handle can be stably clamped by the inventive burglarproof locking device.
