Problems solved by technology

The above-mentioned existing technical solutions have the following defects. When using a single backstop, the driver may drive away directly and forget the backstop, causing economic losses and affecting road safety; when using two backstops at the same time , because they are all single, not integral, inconvenient to carry, and more cumbersome to operate; the pre-tightening force directly applied by manpower is too small to prevent the backstop from losing its position

Embodiment 1

[0023] Such as Figure 1 to Figure 5 As shown, a two-way anti-slip device that can apply a preload to the wheels of an automobile includes two oppositely arranged car stop blocks 1, and the car stop block 1 includes a triangular car stop block frame 101, and in the triangular car stop block frame 101 A triangular elastic anti-slip block 102 is provided. Relying on the elastic deformation of the elastic anti-slip block 102 to closely fit in the block frame 101, the elasticity can be realized by a spring, which is a triangular rubber elastic anti-slip block in this embodiment, and the slope of the triangular rubber elastic anti-slip block is arc-shaped inclined plane. The two anti-vehicle blocks 1 are used to prevent the wheels from slipping before and after the wheels of the car. An intermediate actuator 3 connects the two anti-vehicle blocks 1. A pedaling force applying mechanism 4 connects the two anti-vehicle blocks through the intermediate actuator 3. The block 1 clamps t...

Embodiment 2

[0025] This embodiment is an improvement of the first embodiment, and is a refinement of the connection structure between the stop block 1 and the intermediate actuator 3 in the first embodiment. In this embodiment, the front ends of the first push arm 303 and the second push arm 305 are respectively connected to the two stop blocks 1 through the connecting pin assembly 2, and the connecting pin assembly 2 includes a fourth pin shaft 203, A fixed nut 201 and a pin sleeve 202, the pin sleeve 202 is rotatably connected through the fourth pin 203, and the rear end of the fourth pin 203 is positioned on the pin through the fixed nut 201. In the shaft sleeve 202, the side surfaces of the two pin sleeves 202 are respectively fixedly connected under the sides of the two stop blocks 1, and the front ends of the two fourth pin shafts 203 are respectively hinged to the first pushing block. arm 303 and a second push arm 305.

Embodiment 3

[0027] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment regarding the intermediate actuator 3 . The maximum opening angle of the V-shaped push arm in this embodiment is not greater than 120 degrees.

[0028] The maximum opening angle of the V-shaped push arm can be limited to not more than 120 degrees by setting a stopper on the first pin shaft 304 .

Abstract

The invention relates to a bidirectional anti-slip device capable of applying pre-tightening force to automobile wheels. The device comprises two opposite automobile stopping blocks which are used for being placed in front of and behind the automobile wheels to prevent the wheels from sliding, a middle executing mechanism is connected with the two automobile stopping blocks, and the middle executing mechanism is connected with the two automobile stopping blocks; a treading force applying mechanism clamps an automobile wheel from the front and the back of the automobile wheel through the middle executing mechanism by the two automobile stopping blocks. The device is advantaged in that two car stopping blocks act on the two sides of a tire at the same time through a mechanical structure, the pre-tightening force is increased in the using process, a phenomenon that the car stopping blocks are not in tight contact with wheels is avoided, the anti-slip effect is guaranteed, operation is easy, integrity is high, and the situation that the car stopping blocks are out of position and lost is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of automobile tools, and in particular relates to a two-way anti-skid device capable of applying pretightening force to automobile wheels. Background technique [0002] When the car is parked on a slope, it will be affected by its own gravity to generate a sliding force. Although the frictional resistance of the slope reacts on the tires, and the parking brake of the car will also play a certain role, due to the long parking time or the ground material Smooth and other factors, the car may still appear "sliding car" phenomenon. [0003] Existing vehicle slope stoppers on the market only use a single stopper to place under one side of the tire (the direction in which the car slides), or can use two stoppers to place under both sides of the tire respectively. The above-mentioned existing technical solutions have the following defects. When using a single backstop, the driver may drive away directly and forget...
