Abstract
The utility model belongs to a key part of a tyre deflation type traffic roadblock, in particular relates to a rapid deflation nail which comprises a hollow cylindrical steel nail body. The utility model is characterized in that the head of the steel nail body is provided with a bevel cut seal, and has the advantages that: the deflation nail has the greatest advantages of ideal reliability and short deflation time (only 6 seconds to 18 seconds); meanwhile, the utility model has the characteristics of convenient carrying, rapid laying, flexible control mode and simple and convenient use, etc.; when rolled by a vehicle tyre, the deflation nail is immediately separated from the nail seat of a vehicle stopping belt and firmly pierces into a tyre tube; therefore, an illegal vehicle is stopped within a minimum distance.
Description
Technical field
The utility model belongs to the critical component of the formula traffic roadblock that bleeds a tire, and relates in particular to the quick venting nail that uses on the traffic roadblock that a kind of terrorist of obstruction or offender utilize vehicle to run away.
Background technology
Along with science and technology is maked rapid progress, road extends in all direction, and automobile is widely used.The terrorist adopts automobile as delivery, escape instrument carrying out terrorist activity often, and the crime of driving is executed the task for departments such as public security, People's Armed Police and brought very big difficulty, and therefore the various equipment of holding up traffic arise at the historic moment.At present, People's Armed Police's venting of being equipped with the formula that the bleeds a tire Obstruct apparatus uses is followed closely and is steel triangular pyramid type or hollow metal pipe cutting type.Long, the poor reliability of this venting nail deflation time, vehicle is broken through sometimes, and the venting nail is with askew and can't be penetrated doughnut, though it is simple in structure, processing cost is lower.But in actual use, when the venting pinning was gone into tire, die-cut to the rubber for tire generation, the die-cut rubber skin that gets off entered the steel nail endoporus, stops up air vent, influence venting effect.And the steel nail diameter is big more, and easy more obstruction is exitted slow more or can't be exitted at all.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of quick venting to follow closely, take the method for acupuncture exhaust to force airtyred motor vehicles in short distance, to stop fast travelling, not only deflation time is short for it, and doughnut is in case grind, and the venting nail promptly breaks away from the nail seat of the band of holding up traffic, and penetrates the tire inner core and get rid of and do not take off, cause the crime vehicle in the shortest distance, to halt, prevent its attack important goal.
The utility model for achieving the above object, by the following technical solutions: a kind of quick venting nail, comprise hollow cylinder steel nail body, it is characterized in that: described steel nail body head is provided with scarf and seals.
It is 20-30 ° that described scarf seals angle, preferred 23 °.
The scarf of described steel nail body head is provided with hangnail.
Described steel nail body hollow cylinder sidewall is provided with the air vent of straight-through cylindrical base.
Described air vent position is arranged for dislocation and is provided with.
Described air vent diameter is 5-6mm.
Described steel nail body specification is internal diameter 7.5-8mm, external diameter 9-10mm, long 45mm.
The beneficial effects of the utility model: the sharpest edges of this venting nail are that good reliability, deflation time are short, deflation time 6-18 second, have characteristics such as easy to carry, that laying is quick, control mode is flexible, easy to use, doughnut is in case on grinding, the venting nail promptly breaks away from the nail seat of being with of holding up traffic, and penetrate the tire inner core and get rid of and do not take off, cause the crime vehicle in the shortest distance, to halt.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right pseudosection of Fig. 1.
The specific embodiment
As shown in the figure, a kind of quick venting nail comprises hollow cylinder steel nail body 1, and described steel nail body head is provided with scarf and seals 2.It is 20-30 ° that described scarf seals angle, preferred 23 °.The scarf of described steel nail body head is provided with hangnail 3.Described steel nail body hollow cylinder sidewall is provided with the air vent 4 of straight-through cylindrical base.Described air vent position is arranged for dislocation and is provided with.Described air vent diameter is 5-6mm.Described steel nail body specification is internal diameter 7.5-8mm, external diameter 9-10mm, long 45mm.Through evidence, angle is 23 ° and is with hangnail scarf steel nails than triangular shape, the coniform and easier tire that penetrates of the cutting bar-shaped nail of hollow metal tube, and it is good to penetrate angle, and it is enough to pierce the degree of depth, can not be extruded.The venting nail head adopts seal type, has opened 3 air vents (Ф 5-6mm) on the hollow cylinder sidewall, straight-through hollow cylinder bottom.Like this, when nail penetrates tire, rubber for tire is not produced die-cut, guaranteed the unobstructed of air vent, tire is lost heart.And the intensity guaranteed the venting nail is arranged in the dislocation of air vent, and is indeformable when penetrating tire, do not fracture.Select in the inside and outside footpath of hollow cylinder steel nail, the inside and outside footpath that increases cylinder simultaneously, then the intensity of steel nail is constant, and gas release performance strengthens, but penetrates the probability reduction of tire; Keep the steel nail external diameter constant, increase internal diameter, the probability that then penetrates tire is constant, and gas release performance strengthens, but intensity weakens; Keep the steel nail internal diameter constant, increase external diameter, then gas release performance is constant, strength-enhanced, but the probability that penetrates tire reduces.In order better to solve the contradiction between this three, record through repetition test, the hollow cylinder steel nail of internal diameter Ф 7.5-8mm, external diameter Ф 9-10mm can guarantee that gas release performance is good, intensity is enough, penetrate the rate height.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
