Description

Novel refusal horse

Technical Field

The utility model belongs to the anti-terrorism safety equipment field, concretely relates to novel refusal horse.

Background

Campus security is one of the important components of public security and has been highly valued by countries and society. The campus public safety is guaranteed, the personal life safety of teachers and students is guaranteed, the safety factor of the campus is improved, terrorism and violent activities are effectively dealt with, emergencies are rapidly dealt with, and people pay more and more attention to the campus. In recent years, the level of security protection and security measures in campuses have been increasingly enhanced, particularly in terms of equipment for defense equipment.

The refuge horse is defensive equipment for preventing terrorism and explosion in the campus. The barricade is a mobile type used for blocking obstacles of people and vehicles. When terrorism and violent events impact the campus, the campus security system can rapidly defend key security positions so as to isolate illegal persons and illegal vehicles and prevent the occurrence of illegal violent events; after the danger is eliminated, the danger can be removed in time so as not to influence normal traffic. For this reason, the prior art is equipped with casters at the bottom thereof for easy transportation and movement.

The defects of the prior art are as follows: the existing horse rejecters only have the deterring and blocking effects on people and livestock, but have relatively weak resistance to violent impact of vehicles. This is mainly because: although the prior refusing horses are all provided with the trundles with self-locking functions, the trundles can play a certain locking role, but the contact area of the locking wheels and the ground is small, almost point contact is realized, the friction resistance is small due to the small contact area, so that the stopping force is small when the vehicle impact is resisted, and the stopping effect is weak.

In view of the above disadvantages, the existing barricade improves the structure, such as installing a pulling pin or a ground lock, and although a certain stopping effect is achieved, certain disadvantages are brought about correspondingly: firstly, the site of the defense deployment needs to be fixed, because the ground is preset with embedded parts such as ground piles, ground locks or grooves, and if the temporary defense deployment is carried out in the area without the embedded parts, the advantages of the ground piles and the ground locks still cannot be exerted; secondly, the bulges such as the ground piles and the ground locks are still fixed in the original place when disarming, which seriously interferes with the passing of personnel and vehicles and even causes accidents such as tripping of personnel or scraping and rubbing of vehicles. If the groove is formed, the groove can be blocked due to the accumulation of soil, sand, dust and sundries, the groove must be cleaned frequently, and even the position of the groove cannot be found under the weather conditions of rain or snow. The installation of a pin puller or floor lock has obvious drawbacks.
