Problems solved by technology
However, there are many deficiencies in many anti-riot car gears today, and none of them can be perfect in all aspects, either because the demand for materials is large, the cost is too high, or the structure is not reasonable enough, so that the impact resistance is not enough
Furthermore, the existing anti-riot car gear is generally not efficient in use, not reliable, and occupies a large area, is heavy, and is very inconvenient to maintain

The invention discloses an anti-riot car bumper device, comprising an external box body, an internal box body and a lifting mechanism, wherein the top part of the external box body is provided with an opening, the bottom of the internal box body is provided with an opening, the internal box body is sheathed in the external box body, and the lifting mechanism is positioned in the internal box bodyand is connected with a cover plate of the internal box body and a bottom plate of the external box body. By adopting the structure, the anti-riot car bumper device has the advantages of firm structure and strong impact resistance, and the external box body can favorably play the role of protecting the internal box body and the lifting mechanism, thereby effectively prolonging the service life ofthe device.
Description
technical field [0001] The invention relates to a special anti-riot device, in particular to an anti-riot car stop device which can be used to quickly cut off the passage of vehicles. Background technique [0002] At present, in some specific places, such as government agencies, military agencies, prisons, banks, treasury and other important departments, in the event of riots, robberies and other emergencies, sometimes in order to prevent the expansion of the incident or the escape of relevant personnel, it is necessary to quickly Cut off the road and prevent the passage of vehicles. The more commonly used method of cutting off the road now is to use the anti-riot car block to block the road, so as to prevent the passing of vehicles. However, there are many deficiencies in many anti-riot car gears today, none of which can be perfect in all aspects, either because the demand for materials is large, the cost is too high, or the structure is not reasonable enough, so that the ...
