Embodiment
[0025] Embodiment: a kind of anti-splash barricade nail, made of steel, used to deflate tires in progress, see Figure 1 to Figure 8 Shown, comprise triangular pyramid body 1, be provided with spherical cavity 2 in triangular pyramid body 1, cavity 2 is arranged as spherical, and in spherical cavity 2, distribute some lead counterweight balls 18, because counterweight ball The weight of 18 is relatively large and the counterweight ball 18 is located at the lowest point of the cavity 2, so the setting of the counterweight ball 18 can lower the center of gravity of the anti-splash barricade nail, thus making the anti-splash barricade nail more stable, so it can be more convenient and effective for use. And the triangular pyramid body 1 is provided with an air outlet 3 communicating with the cavity 2, through which the air in the tire is discharged.
[0026] Each apex of the triangular pyramid is provided with a communicating hole 4 communicating with the cavity 2, and each apex...

The invention discloses an anti-splash roadblock nail. The main point of the technical solution is that the anti-splash roadblock nail is set at a sharp point, so that when the anti-splash roadblock nail is used, it can be inserted into the tire faster, and at the same time, for faster alignment The tire is deflated, and after the top of the anti-splash barricade nail is pierced into the tire, the air in the tire generates pressure on the piston cylinder through the air intake groove, and then the top is separated from the base through the first piston rod, thereby forming a larger exhaust Air channel, so the air is discharged from the exhaust channel, so that the tire can be deflated more quickly, and a special locking device is set at the same time, through the movement of the piston cylinder, the locking rod can withstand the tire through the sharp part to increase friction force to prevent the anti-splash barricade spikes from detaching during tire movement, thereby preventing adverse effects caused by flying anti-splash barricade spikes. The invention solves the problem that the existing roadblock nails will splash out due to the high rotation of the tires after they are stuck into the tires.
Description
technical field [0001] The invention relates to the field of police equipment, more specifically, it relates to an anti-splash barricade nail. Background technique [0002] As a kind of police or military equipment, barricade nails are used to deflate the tires of cars under certain conditions, so that the tires lose tire pressure, and further restrict the mobility of specific vehicles, so as to achieve the purpose of chasing fugitives or restricting the enemy. purpose of mobility. [0003] The commonly used barricade nails are generally designed in the shape of a triangular pyramid, which can ensure the stability of the barricade nails on the ground, thereby ensuring that the barricade nails can be more stable when they are in contact with the tires. [0004] For example, a kind of police barricade nail mentioned in the invention patent whose patent notification number is CN103866710A adopts the technical scheme as follows: comprising a body, the body is a hollow triangula...
