Abstract

The utility model relates to a vehicle blocking band, which is especially suitable for the public security department for intercepting criminals who run away by driving. The utility model is formed by a band with nails, and the utility model comprises standard blocks which are formed by plate bodies which are provided with ribs, nails and through holes, and then, the standard blocks are connected into an integrated vehicle blocking band. When the criminals run away by driving, one end of the band is horizontally pulled and is laid on the road which is the front road of criminals who must pass by. When a vehicle is forced to pass by, the nails are penetrated into tires, air in the tires is leaked through the small hole which is arranged on the nails, the vehicle can not be driven, and the purpose of blocking the vehicle can be reached. The ribs which are connected with the nails are pressed by the tires and are broken, and thus, the plate bodies can not be taken away by the tires. According to the use condition, the broken standard blocks by rolling can be exchanged, the utility model can be reused, when the utility model is not used, the utility model can be folded and stored for standby, and the utility model has the advantages of easy use and low cost.

Description

Vehicle blocking band

The utility model relates to a kind of apparatus of interception car, and suitable especially public security department is used to tackle the criminal who drives to abscond.

Original usefulness is blocked the roadblock that bar is made into and has not been had the effect that cuts car.And existing import Vehicle blocking band is a crawler belt shape steel band, the one side of band is evenly equipped with many steel prickers, launch horizontal being layered on the road during use, tire is punctured by steel pricker and leaks gas when vehicle runs over, and makes car have to stop, but do not take away with tire in order to make steel band, must do steel band very heavyly, utilize the deadweight of band that steel pricker is dialled from tire, like this its Heavy Weight, not portable, while cost height.

The purpose of this utility model be to provide a kind of in light weight, portable, can fold, Vehicle blocking band that cost is low.

The utility model is achieved in that Vehicle blocking band is made of the band of band nail, comprises by the plate body that has rib, nail, through hole and forms calibrated bolck, connects into whole Vehicle blocking band by calibrated bolck again.

Fig. 1. structural representation of the present utility model.

Fig. 2. calibrated bolck connects, folding schematic diagram.

Fig. 3. the calibrated bolck partial enlarged drawing.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Plate body (3) is for having the rectangle plate of rib (7), nail (4), through hole (9) above casting with engineering plastics or metal crimp, respectively there is the bearing (5) that through hole is arranged between merely hitting its two edges, two ends.

In the middle of the through hole (9) is nail (4), and nail (4) one ends are for there being the taper shape of aperture (8) on it, and an end is a disk, and the centre is cylindrical, and the periphery of nail (4) is connecting criss-cross 4 ribs (7), makes through hole (9) and nail (4) be linked to be an integral body.1/3 part of nail (4) is at the upper surface of plate body (3).

Each plate body (3) is gone up uniform 4 rows, the through hole (9) of uniform 12 the band ribs (7) of every row, nail (4), and through hole between row (9) dislocation is arranged and is constituted a calibrated bolck (2).Width according to the road needs can utilize the bearing (5) at its two ends to be linked to be the whole all the time Vehicle blocking band in tip of nail (4) up with bearing pin (6) respectively by a plurality of calibrated bolcks (2).

The time spent is not folding with its adjacent two calibrated bolcks (2) at ordinary times, and then all draws close, and is folded into one, and makes nail (4) on it fill up institute to have living space, as shown in Figure 2.Put it in the safety box (1), because an end of Vehicle blocking band is fixed in the safety box (1) as shown in Figure 1 all the time, so the tip of its nail of belt (4) of pulling out when using always up at every turn.

If safety box (1) is taken out in highway section, the place ahead when meeting criminal and absconding at once, with an end of Vehicle blocking band horizontal being layered on the road that pull outward, when vehicle open by force out-of-date, the nail of by the wheel tire pressure (4) thrusts tire, and connected on every side rib (7) disconnects owing to tire weight, air in the tire is missed by the aperture (8) on the nail (4) that thrusts, car is not left how far just open motionless, since between the nail (4) that thrusts and plate body (3) to be connected rib (7) disconnected, plate body (3) just can not taken away by tire.According to mode of occupation, change several rolled over bad calibrated bolck (2) by the wheel tire pressure after, it is folding, collection is in order to using next time.

The utility model is compared with prior art: because Vehicle blocking band utilizes bearing and bearing pin by a plurality of calibrated bolcks Be connected, can change arbitrarily the calibrated bolck of damaging, remainder can be repeatedly, reuse, and improved Utilization rate. Rib because of the nail limit just breaks after the automotive wheels tire pressure is rolled over again, and calibrated bolck can not taken turns Tire is taken away, and then whole Vehicle blocking band weight needn't be done very heavyly, and weight can alleviate greatly, thereby has reduced section The cost of car band. Through hole Heterogeneous Permutation on the plate body, compact conformation has utilized folding space greatly, makes Little, portable, the easy-to-collection of whole Vehicle blocking band volume after folding.

Claims

1. a Vehicle blocking band is made of the band of being with nail, it is characterized in that forming calibrated bolck (2) by the top plate body (3) that has rib (7), nail (4), through hole (9), connects into whole Vehicle blocking band by calibrated bolck (2) again.

2. Vehicle blocking band according to claim 1, it is characterized in that plate body (3) has rib (7) above casting with engineering plastics or metal crimp, nail (4), the rectangle plate of through hole (9), respectively there is the bearing (5) that through hole is arranged between merely hitting its two edges, two ends, in the middle of the through hole (9) is nail (4), nail (4) one ends are for there being the taper shape of aperture (8) on it, one end is a disk, the centre is cylindrical, the periphery of nail (4) is connecting criss-cross 4 ribs (7), make through hole (9) and nail (4) be linked to be an integral body, 1/3 part of nail (4) is at the upper surface of plate body (3).

3. Vehicle blocking band according to claim 1, the through holes (9) that it is characterized in that uniform 12 the band ribs (7) of the every row of upward uniform 4 rows of every plate body (3), nail (4), through hole between row (9) dislocation is arranged and is constituted a calibrated bolck (2), and width as required can utilize calibrated bolck (2) respectively the bearing (5) at its two ends to be linked to be the whole all the time Vehicle blocking band in tip of nail (4) up with bearing pin (6).
