Emergency jacking device for vehicle

Abstract

The invention relates to an emergency jacking device for a vehicle. The emergency jacking device comprises a jacking box with an upper opening; two jacks are arranged inside the jacking box, and the side surfaces of the jacks are provided with jack handles; the side surface of the jacking box is provided with extension arm operating grooves matched with the jack handles, jacking blocks are arranged on the upper portions of the jacks, and a jacking connecting block is connected between the jacking blocks of the two jacks through jacking connecting bolts; and the two jacking blocks and the jacking connecting block form stepped blocks with step connecting parts being the oblique surfaces, and bolts heads of the jacking connecting bolts are embedded into the jacking blocks or the jacking connecting block. According to the emergency jacking device for the vehicle, the opened jacking box is adopted as a main support, the two jacks are arranged in the jacking box, jack heads of the jacks arechanged into plate devices, and the jacking blocks of the two jacks constitute the oblique surfaces through the jacking connecting block; and jacking of failed tires can be achieved, channels allowingthe failed tires to return to the road surface can also be provided, emergency treatment for tire failing on country roads is facilitated, and the emergency treatment time and cost are reduced.

Description

technical field [0001] The invention relates to the field of vehicle jacking equipment, in particular to a vehicle emergency jacking device. Background technique [0002] There will inevitably be some problems in the process of driving the car, so most of the cars are equipped with jacking devices. Most of the existing jacking devices are jacks, which are divided into hydraulic and pneumatic. Most of them can only lift the frame. It is used for overhauling and replacing tires. It has a relatively simple function and cannot cope with some unexpected situations, especially when driving on country roads. Most of the roads are narrow and curved, so it is easy for the tires to fall out, even for old drivers. Such failures will occur, and most of the treatment methods when such failures occur are to call a crane. Because it is in the countryside, the processing time of calling a crane is mostly time-consuming, requiring the owner to wait for a long time, and the cost is high, so c...

Problems solved by technology

[0002] There will inevitably be certain problems during the driving process of the car, so most of the cars will be equipped with jacking devices. Most of the existing jacking devices are jacks, which are divided into hydraulic and pneumatic. Most of them can only lift the frame. liter, used for inspection and replacement of tires, the function is relatively simple, and it cannot cope with some unexpected situations, especially when driving on country roads, most of which are narrow and curved, so it is easy for tires to fall flat, even for old drivers. There will be such a failure, and most of the handling methods when this kind of failure occurs are to call the crane. Because it is in the countryside, the processing time of the crane is mostly time-consuming, requiring the owner to wait for a long time, and the cost is high, so continue to design A jacking device that can jack up the tires that have fallen through the ground, so that the car can open the circuit normally
