In order to achieve the technical purpose, the technical scheme of the invention is as follows:
the utility model provides a pneumatic swift current car device of preventing, is including preventing the hook of taking a walk, the middle part perpendicular fixation of preventing the hook of taking a walk has the couple board, the couple board is kept away from the one end of preventing the hook of taking a walk and is equipped with two guide orifice plates of parallel arrangement, two guide orifice plates are equipped with the guiding hole along vertical direction, two pass in the guiding hole have round pin axle I, the one end of round pin axle I is equipped with the nut, round pin axle I passes the opening on the couple board, the one end of deflector is fixed on the automobile body, the top of round pin axle I is equipped with the single-action cylinder, the single-action cylinder is located the hinge point seat, round pin axle I passes the hole of hinge point seat, the lower extreme of preventing the hook of taking a walk is connected with the otic placode through round pin axle II, single-action cylinder, otic placode all with automobile body fixed connection.
Further, the single-acting cylinder is connected with a two-position three-way hand-pulled reversing valve.
Further, the single-acting air cylinder is a single-acting spring return air cylinder.
Further, the hook plate is fixed on the anti-walking hook through welding.
Further, the aperture of the hinge point seat is larger than the aperture of the guide hole.
The invention has the beneficial effects that: the defect that the existing pneumatic anti-slip device has high requirement on the cylinder and the cylinder is easy to damage is overcome, the cylinder is basically not required to be replaced, and the maintenance cost is reduced; the anti-slip hook acts rapidly and flexibly, replaces the traditional manual control mode, and enables a driver to put down the anti-slip hook at the first time when finding the sliding trend, so that accident deterioration is prevented, and property and personal safety are guaranteed.
