Example Embodiment

[0008] On the ramp, hold the handle 1 and rotate it so that the hanging rod 8 is out of the suspension position. Under the action of gravity, the connecting shaft 7 and the movable block 5 of the device move down to touch the road surface. When the vehicle moves forward, the rolling wheel 6 touches the road surface and rolls forward. The spring 4 is elongated, when the vehicle slides backward, the movable block of the device contacts the road surface, the friction restricts the movable block to move backward, the spring 4 retracts without force, and the meshing surface 3 of the movable block 5 of the device and the fixed block of the device fixed on the vehicle 2's meshing surface 3 contacts, and now the movable space of the movable block of the device is limited, and the movable block of the device will be in close contact with the road surface, which will generate a great support force and avoid further slipping of the vehicle.

[0009] In order to avoid rotation and overturn...

Abstract

The invention discloses a device for preventing a car from slipping backwards on a ramp, and relates to the field of vehicle structures, in particular to a facility for preventing a vehicle from slipping backwards on the ramp. The vehicle is easy to slip backwards to cause the danger on the ramp. The device for preventing the car from slipping backwards on the ramp aims to overcome the disadvantage that the vehicle slips backwards on the ramp. The technical scheme is that: a handle can pull up an anti-back-slip device and is provided with a hanging rod, the hanging rod ensures that the anti-back-slip device can be hung, and the vehicle can only apply a reversing function after two movable blocks are hung; the two movable blocks of the device are connected by a connecting shaft; fixed blocks of the device are fixed behind front wheels, the movable blocks of the device and the fixed blocks of the device are connected by springs, each movable block of the device and each fixed block of the device are provided with an engagement surface respectively, and a small rolling wheel is arranged on the front part of each movable block of the device; and the surface, which is contacted with the ground, of each movable block of the device is made of an antiskid material. The invention has the advantages that the device limits the vehicle to slip backwards, so that the driving on the ramp is relatively safe; the device has a simple and effective structure, and does not affect the driving of the vehicle; and the engagement surfaces ensure the stability of contact performance.

Description

technical field [0001] The invention relates to the field of vehicle construction, in particular to a facility for preventing vehicles from slipping backwards on slopes. Background technique [0002] When the vehicle is on a slope, due to insufficient power or insufficient braking force, the vehicle will slip backward under the action of gravity, and places with slopes often face cliffs, and there is a risk of car crash and death if you are not careful. Contents of the invention [0003] In order to overcome the vehicle slipping backwards on the ramp, the present invention designs a device for preventing the vehicle from slipping backwards on the ramp. [0004] The technical solution adopted by the present invention to solve the technical problem is: the anti-backward slipping device of the trolley ramp is composed of a fixed block, a movable block, a spring, a connecting shaft and a handle, the handle is connected to the connecting shaft, and the handle can pull up the an...
