The purpose of enemy's ability to act.
Existing frequently-used road barricade nail, is generally designed to triangular pyramid shape, can so ensure efficient road barricade nail on ground
Stability so that ensure efficient road barricade nail can be contacted when being contacted with tire more consolidate.
A kind of police road barricade nail that such as patent announcement number is mentioned for CN103866710A utility model patent, what it was used
Technical scheme is：Including body, the body is hollow triangular pyramid, is both provided with each summit of the triangular pyramid vertical
Steel nail, the steel nail is hollow structure, is both provided with helicla flute on the inner and outer wall of the steel nail, each steel nail it is interior
Portion is all interconnected.The police efficient road barricade nail has the beneficial effect that：Simple in construction, the steel nail hole being connected using inside can
The rapid gas for bleeding off tire, it is the time for allowing ruffian not escape, obstructive good, it is easy to carry, it is with low cost, it is easy to which that popularization makes
With.
However, steel nail hole is arranged to hollow by above-mentioned police road barricade nail based on for the purpose to the faster deflation of tire
Shape, hollow shape causes the top of steel nail not sharp enough, therefore in actual use, steel nail can not more preferably more rapidly
Penetrate in tire, be unfavorable for more quickly bleeding a tire.Therefore designing a kind of sharp can faster penetrate tire simultaneously
Tire quickly deflate and is necessary.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is that tire can be quickly pierced into simultaneously by providing one kind
Being capable of not the efficient road barricade nail deflated of rapid pair-wheel tire.
To achieve the above object, the utility model provides following technical scheme：A kind of efficient road barricade nail, using steel system
Into for being deflated to the tire in traveling, including triangular pyramid body, cavity, and institute are provided with the triangular pyramid body
The venthole for being provided with and being connected with the cavity on triangular pyramid body is stated, the summit of the triangular pyramid is provided with to be connected with the cavity

Positioned at the top of piston body 10.Upper cylinder half 71 is provided with some exhaust passages 15 close to the position of top surface 8.Exhaust passage 15 such as figure institute
Show, exhaust passage 15 bypasses air inlet duct 11 and is not drawn into.Exhaust passage 15 is connected by intercommunicating pore 4 with cavity 2, therefore top 6
Air is quickly discharged from exhaust people having a common goal after being opened.
The sealing land 13 with the grafting of upper cylinder half 71 is provided with top 6, the presence due to sealing land 13 can prevent top
Point 6 is inserted into after tire, and gas enters the problem of causing top 6 can not be opened in upper cylinder half 71 in tire.
First piston bar 9 and second piston bar 12 are connected to above and below piston body 10, wherein First piston bar 9 is located at
Upper cylinder half 71, while being fixedly connected with the center of top 6 lower end, second piston bar 12 is located in lower cylinder 72, and described second
The bottom of piston rod 12 is connected with locking device.The side of matrix 5 is connected with equally distributed four air inlet ducts 11, air inlet duct 11
Connected with lower cylinder 72.Gas in using process tire is flowed into piston cylinder 7 from air inlet duct 11, due to the He of exhaust passage 15
The presence for sealing land 13 is connected by cavity 2 with external atmosphere pressure due to upper cylinder half 71, thus piston have pressure difference up and down, because
This piston body 10 can move and then cause matrix 5 and top 6 disengaging.
The bottom of second piston bar 12 is connected with locking device, and locking device includes being connected with the bottom of second piston bar 12
Check lock lever, the top of check lock lever, which is provided with sharp portion 14, sharp portion 14, is provided with point-like projection 171 and line shape projection 172
Can effective increasing friction force, while it is more convenient to manufacture processing.
Check lock lever can be moved in the air inlet duct 11 along the above-below direction of second piston bar 12, be contacted with matrix 5 when top 6
When, sharp portion 14 is hidden in air inlet duct 11, when described top 6 away from described matrix 5, the sharp portion 14 stretch out it is described enter
Air drain 11, height of the air inlet duct 11 on the direction of First piston bar 9 is less than the thickness of tire.By check lock lever and second piston
Bar 12 set it is at 45 ° enable to check lock lever stretching while it is oblique be inserted into tire, further by efficient roadblock
Nail is fixed in tire, gets rid of its tire being not easy in being traveling.
Check lock lever includes the lower beam 19 being connected with second piston bar 12, and lower beam 19 is connected with upper boom 20, upper boom 20 and set
There is the jack 23 being provided with plug 22, lower beam 19 with the grafting of plug 22, be also associated with inciting somebody to action between plug 22 and jack 23
The spring 21 of deformation is produced when plug 22 is pulled out from jack 23, it is another relative to jack 23 that sharp portion 14 is located at upper boom 20
Side.Check lock lever is divided into lower beam 19, upper boom 20, because upper boom 20 is inserted into tire by sharp portion 14, when we need by
When efficient road barricade nail takes out from tire, upper boom 20 can be separated with tubulose rod set and still can still connected by spring 21, when taking
Go out behind matrix 5 and top 6 us easily can be just taken out upper boom 20 by spring 21 using instruments such as pliers, be taken out
After reinstall in tubulose rod set, remain able to reuse.
In addition, being provided with top 6 for preventing top 6 magnet 16 departed from from matrix 5 under off working state.Set
Magnet 16 enables to top 6 to depart to be convenient to use from matrix 5 in a non-operative state.
When in use, when running car is gone over, tire can contact and can penetrate tire the efficient road barricade nail with top 6
In, because top 6 are set in cone in the utility model, therefore, it is possible to penetrating among tire quickly, puncture mechanism
Gradually it can penetrate among tire, until air inlet duct 11 starts to be contacted with the air in tire, now due to air inlet duct
11 height is less than the thickness of tire, and now air is entered among piston cylinder 7, due to the pressure of air so that promote piston
Body 10 is moved, and motion is started simultaneously at because piston body 10 is connected to top 6, therefore top 6 by First piston bar 9 and chuck,
Therefore now top 6 start depart from matrix 5, due to being provided with the exhaust passage 15 connected with cavity 2 on the top surface 8 of matrix 5, this
When exhaust passage 15 open, be now exhausted by exhaust passage 15, due to exhaust passage 15 can be rapidly performed by exhaust
Therefore, it is possible to more quickly discharge the gas in tire；Because piston body 10 is lived by second while piston body 10 is moved
Stopper rod 12 drives locking device motion, in motion process, and check lock lever is moved in air inlet duct 11, so as to stretch out air inlet duct
11, so that check lock lever top has been arrived on tire, preferably it can be connected due to being provided with sharp portion 14 on check lock lever with tire,
Bad influence is brought therefore, it is possible to prevent efficient road barricade nail splashing in tire rotary course.
To sum up, the utility model can quickly be inserted into tire and tire be carried out quick in use
Deflate, the efficient road barricade nail have the advantages that it is easy to use, while the efficient road barricade nail in use will not be from rotation
Danced in the air on tire, it is to avoid have undesirable effect；And can be disassembled after the completion of the efficient road barricade nail use from tire, weight
Use again.
Described above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
