Problems solved by technology

[0003] During the operation of the vehicle, there will be accidents where one or two of the wheels fall into the ditch or ridge, or even the accident where the wheel is out of the road. Since the drop between the road surface and the bottom of the ditch or ridge is greater than the height of the jack, it is very difficult in this case. Difficult to rescue
[0004] Especially in the wild, when the driver is driving alone, without the assistance of other people, if the above-mentioned accident occurs, it will be more difficult for the driver to save himself
[0005] At present, in response to the above-mentioned accidents, it is usually rescued by placing stones, sand, and wooden boards under the wheels or using human power to push the vehicle. If the filling is not dense, it is difficult to ensure safety during the self-rescue process of the car, and the expected effect is often not achieved. At present, there is no emergency rescue equipment that can be operated alone in the field to complete the self-rescue of the vehicle

Abstract

The invention relates to hand-operated triple-folding-bridge self-locking rescue equipment, in particular to emergency rescue equipment which is used for automobile rescue and can bear load and realize quick supporting. A three-section foldable platform is arranged at the top end of a hand-operated jack with an extensible rod, the extensible rod is arranged between the platform and a hydraulic jack, and two groups of tooth-shaped protrusions are formed inside an outer sleeve body of the extensible rod. The equipment can realize self rescue through independent operation, so that manpower, financial resources and time are saved greatly; a wheel of a vehicle is supported through the three-section foldable platform on the jack, self rescue is completed by adjusting longitudinal-transverse direction of the three-section foldable platform, and longitudinal translation and transverse translation of the vehicle can be realized through the three-section foldable platform, so that safe and labor-saving operation is realized, the objective of bringing convenience to operation is achieved, and the equipment is high in practicability.
