A roadblock device that prevents tires from being punctured in reverse

Abstract

The invention relates to a roadblock device being strong in stability, capable of preventing going in a direction not allowed by traffic regulations and capable of puncturing tires. The roadblock device comprises an upper frame, a protective sponge plate, a rubber filling layer and a threaded rod. A sliding groove is installed below the upper frame, the inner side of the sliding groove is providedwith a lower frame, the upper frame is fixedly connected with the sliding groove, the sliding groove is movably connected with the lower frame, the protective sponge plate is installed inside the lower frame, a small air pump is arranged on the inner side of the protective sponge plate, and the protective sponge plate and the lower frame are movably connected; and the small air pump and the lowerframe are in screw connection, the rubber filling layer is installed at the bottom of the lower frame, and the inside of the lower frame is provided with a clamping spring. The roadblock device has the beneficial effects that the roadblock device being strong in stability, capable of preventing going in the direction not allowed by the traffic regulations and capable of puncturing the tires is provided with a stepping plate, protruding stabs can be retracted back, damage caused by the protruding stabs to normal traveling vehicles is prevented, and economic losses caused by normal traveling vehicle maintenance are avoided.

Description

technical field [0001] The invention relates to the technical field of road barrier devices, in particular to a road barrier device capable of preventing tires from being punctured in reverse. Background technique [0002] At the intersection of some roads or the entrance of an area, it is often necessary to set up roadblocks to control road traffic. For example, in order to prohibit the passage of vehicles or the passage of motor vehicles exceeding the norms, the roadblocks are also called ejection remote control vehicle interceptors and stop nails. , it is applied in traffic safety, and can achieve the purpose of quickly and safely intercepting vehicles. [0003] The existing built-in roadblock device is generally fixed to the ground with cement when it is in use, which will make it impossible to take out and observe conveniently when the device breaks down, thus making the maintenance of the device more difficult and longer. Some devices are generally assembled in multip...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a roadblock device that can prevent tires from being punctured in reverse, so as to solve the problem that the existing built-in roadblock device proposed in the above background technology generally uses cement to fix it to the ground when in use, so It will lead to the inability to conveniently take out and observe when the device fails, which will increase the difficulty and time of maintenance of the device, and the existing devices are generally assembled with multiple devices, but each device is not connected.
