Portable tire breaker

Abstract

A portable vehicle stop tire breaker solves the problems that an existing tire breaker is complex in structure, relatively poor in stability and poor in tire breaking effect and can hurt a person mistakenly. The portable vehicle stop tire breaker is characterized in that at least one module base is installed in an aluminum alloy combined base; each module base is provided with tire breaking nails and a protective cover; rolling locating end covers are installed on the left side and the right side of the combined base; the thickness is in normal distribution from the top wall of the protective cover to the side walls of the protective cover; the protective cover is connected with protective cover buckle installation clamping grooves of each module base through protective cover buckles folded inwards flatly; and symmetric oval holes are formed in the rolling locating end covers. The portable vehicle stop tire breaker has the beneficial effects that the aluminum alloy combined base is of a cavity structure, the strength is high, the bottom face is provided with serrated strips, the adhesive force between the bottom face and the ground is improved, the tire breaker falls to the ground and grabs the ground more stably, the perpendicularity and stability of the tire breaking nails can be better guaranteed, the tire breaking nails are prevented from laterally falling, it can be guaranteed that the human body is not harmed due to the wall thickness of the top wall of the protective cover, and the tire breaker can be more conveniently and rapidly grabbed and placed by a user through the arrangement of the rolling locating end covers.

Description

technical field [0001] The invention belongs to the technical field of roadblocks, and in particular relates to a portable tire breaker for stopping vehicles, which is police equipment for effectively intercepting vehicles by setting up obstacles on the road when police officers perform tasks. Background technique [0002] A roadblock is an obstacle placed on the road by the people's police when performing their duties. Traffic police often need to stop vehicles that violate traffic rules when enforcing the law. In order to prevent the stopped vehicles from escaping, prevent collisions, and ensure the life safety of police officers on duty, police officers on duty generally use tire breakers to stop roadblocks. The tire breaker is a kind of tire deflation roadblock, and the tire breaker can play a good deterrent effect on drivers who are stalemate and do not cooperate. [0003] Existing roadblocks are basically divided into two types, one is fixed roadblocks, such as anti-t...

AI Technical Summary

Problems solved by technology

However, the metal base of this utility model is equivalent to a C-shaped equal-thick groove strip, which has low strength and poor stability. The bottom surface is an arc-shaped groove structure, which has poor adhesion to the ground and is easy to slide. The end plate at the end is a flat plate structure, which is poor in handholdability and is inconvenient for police officers to use. The base and shield of the tire breaking mechanism are made of ordinary plastic. The base of the tire breaking mechanism is located below the vertical through hole. and the vertical through hole communicates with the horizontal groove, the horizontal groove is provided with a steel nail top plate, the lower end of the steel nail in the vertical through hole is in contact with the steel nail top plate in the horizontal groove, here, the shield is trapezoidal and the wall thickness Consistent, the bottom part in the figure is a seal, which is not conducive to being destroyed instantly after being stressed, and will affect the effect of tire breakage. The lower end of the steel nail in the vertical through hole is in contact with the top plate of the steel nail in the horizontal groove, and the steel nail hole is relatively small. Shallow, the stability of steel nails is poor

[0006] In addition, the function of the tire breaker housing or shield in all prior art is mainly to be convenient for the policeman who handles on-site to be easy to carry, and can protect the policeman from being broken by the broken tire in the tire breaker when carrying the tire breaker. Needle stick injuries, did not consider the situation of police officers in use to prevent accidental injury to pedestrians
