Abstract
The utility model relates to a portable thorny road grid, which is composed of a fixing box (1) with a double-face open package, a double diamond chain type aluminum base seat (2), a circlip screw (3), and a row broken cone (4) in a triangular pyramid shape. The three side faces of the row broken cone (4) in a triangular pyramid shape are provided with holes (slots) and barbs. The portable thorny road grid is suitable for law military guards to effectively block criminals which escape by car, and can force wheeled vehicles which run in high speed to stop. The portable thorny road grid can be used for blocking cross roads; on military, the portable thorny road grid is used for stagnating enemies' actions or trapping, etc. The utility model has the advantages of light weight, high reliability, convenient maintenance, and convenient implantation and withdrawal.
Description
The present invention is a kind of portable perverse tire road grid, be applicable to that the law enforcement army and police block the criminal who drives to run away effectively, can force the wheeled vehicle stagnation of movement of running at high speed rapidly, also can be used for blocking and be used to block enemy action in crossing, thoroughfare and the military affairs around the spot of the accident or be used to capture enemy personnel etc.
In order to stop the ruffian who takes motor vehicles effectively, some perverse device of tyre have been developed both at home and abroad, for example the THE MOUNTIES is under its defence organization's assistance, a kind of " traffic stud " (ICPR161～162 in 1985) have been developed, it is to insert the adhesive tape the inside that four layers of rubber strip are woven into by the two or more rows hollow nail, liner is made with metal in the bottom of adhesive tape, can rolling.This road grid production technology is complicated, and rolling is slower, and China Shanxi People's Armed Police department developed a kind of highway in 1984 and intercepted device, the similar Ancient Times in China weapons of its structure " mace ", the road surface is blocked in the segmentation assembling, this apparatus structure is heavy, and inconvenience is handled in duties.
The technical problem that the present invention is directed to domestic and international perverse tire road grid existence at present designs, and purpose is to realize a kind of being easy to carry, and is convenient to the technical scheme of the perverse tire road grid of quickly retracting, and requires production technology simple, is convenient to transportation and maintenance.
The following description has realized this purpose preferably.
Portable perverse tire of the present invention road grid, by the two-sided packing of opening the door, fixed case (1), two water chestnut chain type aluminium bases (2), jump ring screw (3) and row breaking cone (4) are formed.This technical scheme is the improvement project of our design " two water chestnut chain type base steel seats, the portable perverse tire road grid of solid welding cement nailing " design scheme in 1987.Perverse at ordinary times tire road grid voltage contracts to roll over and is placed in the two-sided packing of opening the door, the fixed case (1), to pack fixed case (1) during use and be placed on the side on the road surface that will block, the one side that will have nylon rope is aimed at highway central authorities, open this face rapidly, the pulling nylon rope is gone to the highway another side, two water chestnut chain type aluminium bases are taken and are worn row breaking cone and launch rapidly, block this road section surface.
The two-sided packing of opening the door, fixed case (1), its loam cake is opened, so that road grid (new product or repair product) are cased and fix.Three balance slide rails are housed on the bottom surface of fixed case (1), and a middle one slide rail inside has groove, so that connect with the road grid; Side direction is opened the door so that duties when laying roadblock, fast the road grid being pulled out or removed the time receiving pushes, the parts that two water chestnut chain type aluminium bases are made up of the hinge of the Double Diamond that band jump ring screw and scalable motion are housed, its left side connection solid in packing case in the middle of in the slide rail, the right side has nylon withdrawal line, this pedestal (2) adopts the riveted joint of polylith aluminium alloy plate to form, and is convenient to repair dismounting.Jump ring screw (3) is made up of jump ring (5) and interrupted screw (6), connecting employing screw thread and epoxy resin with pedestal fixes, its effect is fixing row breaking cone (4), row breaking cone (4) does not come off when guaranteeing transportation and duties processing, after row breaking cone penetrates into tire, row breaking cone hightails pedestal, row breaking cone (4) is the triangular taper, there is the steam vent (groove) of perforation middle and three sides, it is to destroy tire, make the functor of the quick exhaust of tire, three faceted pebbles of row breaking cone have the hangnail of anticreep, after row breaking cone penetrates into tire, hangnail snaps in tire, and by the tire band from pedestal, row breaking cone three-side blowing groove and intermediate exhaust hole make rapidly that gas releases in the tire, and vehicle can't be travelled because of tire is flat.
Major advantage of the present invention:
1, " two water chestnut chain type pedestal " adopts aluminum alloy materials, and weight is lighter; Carrier bar adopts riveted joint, and activity is convenient to drawing and maintenance freely;
2, band jump ring screw inserts row breaking cone, make row breaking cone guarantee that really in transportation, duties do not come off when handling, and after penetrating into tire, row breaking cone can hightail pedestal;
3, the row breaking cone that has air discharge duct, hole and hangnail, perverse tire is rapid, and it is reliable to lose heart;
4, two-sided packing, the fixed case of opening the door both played the packing effect, played fixedly road grid effect of an end again, and for packing into, the perverse tire of tension and compression road grid are very convenient and reliable.
Fig. 1 is one embodiment of the present of invention to Fig. 3.This portable perverse tire road grid length of run reaches 8.5 meters, has 148 pieces of row breaking cones on it, can stab out a various wheeled motor vehicles tire, forces vehicle lay-off.
