Description
Technical Field
The invention relates to the field of police equipment, in particular to a high-efficiency road barrier nail.
Background
The road barrier spike is used as police or military equipment, and is used for performing deflation operation on a tire of an automobile under a specific condition, so that the tire loses tire pressure, the mobility of a specific vehicle is further limited, and the aim of pursuing evasion or limiting the mobility of an enemy is fulfilled.
The barrier nail commonly used now, general design becomes the triangular pyramid shape, can ensure high-efficient barrier nail stability on ground like this to guarantee that high-efficient barrier nail can contact more firm when contacting with the tire.
For example, the invention patent with patent publication number CN103866710A discloses a police road barrier nail, which adopts the technical scheme that: the steel nail fixing device comprises a body, the body is hollow triangular pyramid, all be provided with vertically steel nail on every summit of triangular pyramid, the steel nail is hollow structure, all be provided with the helicla flute on the inner wall of steel nail and the outer wall, the inside of every steel nail all communicates each other. This it is alert with high-efficient roadblock nail's beneficial effect does: the structure is simple, the air in the tires can be rapidly released by utilizing the steel nail holes communicated with the inside, so that gangsters do not have the time to escape, the obstruction is good, the carrying is convenient, the cost is low, and the popularization and the use are easy.
However, the police barrier nail is based on the purpose of deflating the tire faster, and the steel nail hole is set to be a hollow shape, and the top of the steel nail is not sharp enough due to the hollow shape, so that in the actual use process, the steel nail cannot be pricked into the tire faster and better, and the tire deflating speed is not fast. It is therefore highly desirable to design a sharp tip that can penetrate the tire more quickly and deflate the tire quickly.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a high-efficiency road barrier spike which can quickly puncture a tire and can also quickly deflate the tire.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a high-efficient road barrier nail, adopts steel to make for deflate to the tire of marcing, including the triangular pyramid body, this internal cavity that is provided with of triangular pyramid, just be provided with on the triangular pyramid body with the venthole of cavity intercommunication, the summit of triangular pyramid be provided with the intercommunicating pore of cavity intercommunication, its characterized in that: each vertex of the triangular pyramid body is vertically connected with a piercing mechanism, the piercing mechanism comprises a base body fixedly connected with the triangular pyramid body, the top end of the base body is connected with a conical tip, the base body and the tip are connected to form a cone shape, the contact surface of the base body and the tip is called a top surface, a piston cylinder is arranged at the center of the base body, a piston body slides in the piston cylinder in a sealing manner, the piston cylinder is divided into an upper cylinder and a lower cylinder by the piston body, the upper cylinder is intersected with the top surface, an exhaust channel is arranged at the position close to the top surface, and the exhaust channel is communicated with the cavity through a communicating hole; the top is provided with a sealing ring platform which is inserted into the upper cylinder; the upper part and the lower part of the piston body are respectively connected with a first piston rod and a second piston rod, wherein the first piston rod is positioned in the upper cylinder and is fixedly connected with the central position of the lower end of the centre, the second piston rod is positioned in the lower cylinder, and the bottom end of the second piston rod is connected with a locking device; a plurality of air inlet grooves are uniformly formed in the side face of the base body and are communicated with the lower cylinder; the locking device comprises a locking rod connected with the bottom end of the second piston rod, a sharp part is arranged at the top end of the locking rod, the locking rod can move up and down along the second piston rod in the air inlet groove, and when the sharp part is contacted with the base body, the sharp part is hidden in the air inlet groove; when the tire is punctured by the puncturing mechanism, gas enters the lower cylinder from the air inlet groove, the piston body drives the tip to be far away from the base body due to the fact that the upper cylinder and the lower cylinder have pressure difference, and the sharp-pointed part extends out of the air inlet groove and punctures into the tire; the height of the air inlet groove in the direction of the first piston rod is smaller than the thickness of the tire.
Through adopting above-mentioned technical scheme, four are punctureed the mechanism at four summits of triangular pyramid perpendicular installation respectively, and when high-efficient road barrier nail was placed on subaerial, high-efficient road barrier nail was in a relatively stable state. When the vehicle is driven, the tire comes into contact with the apex and can be punctured into the tire, since the apex is conically disposed in the present invention, therefore, the puncture mechanism can be punctured into the tire quickly, the puncture mechanism can be punctured into the tire gradually until the air inlet groove is contacted with the air in the tire, at the moment, because the height of the air inlet groove is less than the thickness of the tire, the air enters the piston cylinder, the piston body is pushed to move due to the pressure of air, the finials start to move simultaneously as the piston body is connected with the finials through the first piston rod and the clamping table, and then the finials start to separate from the base body, after the top surface of the basal body is opened, the upper cylinder is internally provided with an exhaust channel communicated with the cavity, the exhaust channel is opened at the moment, the exhaust is carried out through the exhaust channel at the moment, the exhaust channel can exhaust gas quickly, so that the gas in the tire can be exhausted quickly; because the piston body passes through the second piston rod and drives locking device motion when the piston body moves, at the motion in-process, the check lock lever moves in the air inlet duct to stretch out the air inlet duct, therefore make the check lock lever push up on the tire, because be provided with sharp portion on the check lock lever can be better be connected with the tire, consequently can prevent that the rotatory in-process high-efficient roadblock nail of tire from dancing and bringing bad influence.
