Catapulting type deflating nail

Abstract

The invention relates to the technical field of security protection equipment, in particular to a catapulting type deflating nail. The catapulting type deflating nail comprises a box body, a nail plate mechanism, an opening mechanism and a firing mechanism. The box body is mainly composed of a bottom box and an upper box cover. The front portion of the bottom box is provided with a portal frame. The two sides of the portal frame are provided with security pins respectively. The upper portion of the portal frame is provided with an opening pin. The two sides of the bottom box are provided with sliding rails respectively. The nail plate mechanism is matched with the sliding rails and is mainly composed of a nail base, a nail plate and a tire breaking nail. The nail base is fixed to the nail plate. The tire breaking nail is installed on the nail base. The opening mechanism is arranged on one side of the bottom box. The pedal-touch catapulting type vehicle deflating nail is made of stainless steel and hard alloy, is of a full-mechanical structure, is not limited by weather, environment and regions, and can be normally used in the humid environment.

Description

technical field [0001] The invention relates to the technical field of security equipment, in particular to an ejection type deflation nail. Background technique [0002] At present, most of the deflated and tire-breaking devices used in vehicle interception are deflated nails and tire breakers controlled by remote control systems. These devices need to be placed or laid in advance in use, and their flexibility is limited to a certain extent. Certain restrictions. For example, what is commonly used for stopping vehicles in the prior art is a nail plate. After the suspect's vehicle in front ran over the nail plate, most of the thorns remained on the road, causing the chasing police car to dodge and be intercepted and deflated by the remaining thorns. CN103233438 discloses a portable remote-controlled ejection-type car-blocking spike net, and an improved technical solution is proposed for the above situation: when the suspect vehicle rolls over the spikes of the portable rem...

Problems solved by technology

The disadvantage of CN103233438 is that the remote control ejection type car-blocking nail net is heavy and not suitable for carrying around; in addition, after the nail enters the vehicle tire, the nail is provided with a barb groove so that it can hook the inner wall of the tire; In this way, the tires of the suspected vehicle will not be deflated in a short period of time and can still drive normally.

If the wire rope of the nail net is not wrapped around the tire, it will cause damage to the following police car, making the case detection miss the opportunity, and will bring greater hidden dangers to social security.

[0003] Both of the above two deflation nails use remote control to open the deflation nails, but because the deflation nails are generally not used frequently, some may not be used once, which requires regular replacement of the batteries inside, otherwise, If the battery fails, the remote control will not be possible, which will cause inconvenience to the user.
