Abstract

The utility model discloses a tyre spiking device with three edges and four tips, which comprises four tyre spiking spine objects which are uniformly distributed in the shape of radiation from the middle to the outside, wherein the spine is in a triangular pyramid shape from the tip to the root and a cone angle is from 25 DEG to 35 DEG. A cone face arranged between two adjacent cone edges is convexly provided with a convex edge, and air exhausting grooves are formed on both sides of the convex edge. The tyre spiking device with three edges and four tips provided by the utility model has good tyre spiking and interception effects to different vehicles of different kinds by improving the spine structure of the tyre spiking device with four tips existing in the prior art. When the spine of the tyre spiking device penetrates into a tyre, the compressed air in the tyre is instantly discharged from the middle of the air exhausting groove to the outside and air pressure in the tyre is rapidly reduced so that an automobile can not be driven.

Description

Tyre spiked device with three-edge and four-tip

Technical field

The utility model provides a kind of public security equipment of tackling automobile, especially a kind of can by puncture doughnut stop automobile by force by or the tyre spiked device with three-edge and four-tip of escaping.

Background technology

The four sharp tire bursters that the utility model relates to are the utensil of four the broken tire spines that evenly distribute from mind-set external radiation shape wherein, this utensil when arbitrarily throwing away on the ground always the time one of them spine up, and three other spines form three strong points and support on the ground reposefully.When the automotive wheels tire pressure was crossed this tire burster, spine up just can puncture tire.Of the prior art four sharp tire bursters as shown in Figure 1, 2, because there are some defectives in its structure, cause brokenly the tire poor effect, major defect is, spine is sharp-pointed inadequately, and the angle at spine 01 tip 02 of existing tire burster 10 is 64 degree, and be sharp-pointed section just at most advanced and sophisticated one section, be non-conical section to lower part 03, therefore, the tire tougher for tire punctures poor effect; In addition, the spine of existing tire burster is longer, can push it to when the wheel of dilly is met it on one side to pass through; Have, do not establish the exhaust structure (see figure 2) on the spine of existing tire burster, it is slower that tire burster is pricked on the tire final vacuum, blocked vehicle and can continue long to overtake segment distance, and it is unfavorable to tackle.

Summary of the invention

The purpose of this utility model is to improve deficiency of the prior art, and a kind of tyre spiked device with three-edge and four-tip that can effectively fast tackle large and small vehicle is provided.

The purpose of this utility model is achieved in that

The tyre spiked device with three-edge and four-tip that the utility model provides comprise one from the centre outside four broken tire spine objects of radial even distribution, described spine is triangular pyramid shape from the tip to the root, cone angle is the 25-35 degree, on the conical surface between two adjacent awl ribs, convex with fin, form air discharge duct in the both sides of fin.

For the suitable tire that punctures all size vehicle, when three described spines supported ground, the thorn point of the 4th spine up was preferably the 50-70 millimeter to the height on ground.If spine is short excessively, for thicker oversize vehicle of tire etc., it can not be punctured, or cut may be too small, make the obstruction deleterious.

With convenience shed and regain, be provided with perforation at the mid portion of this tire burster, wear rope therein, several these tire bursters are coupled together form the tire burster chain.

The tyre spiked device with three-edge and four-tip that the utility model provides passes through the improvement to the spine structure of four sharp tire bursters of the prior art, make it well broken tire interception result all be arranged to big or small all kinds vehicle, when the spine of this tire burster pierces into tire, the tire compressed air can be released to the outside from air discharge duct immediately, the tire internal gas pressure is descended rapidly, and automobile can not travel.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of existing four sharp tire bursters;

Fig. 2 is the structural representation of cross section of the spine of tire burster shown in Figure 1;

The structural representation of the tyre spiked device with three-edge and four-tip that Fig. 3 provides for the utility model;

Fig. 4 is the structural representation of cross section of the spine of tire burster shown in Figure 3.

The specific embodiment

As illustrated in fig. 1 and 2, the tyre spiked device with three-edge and four-tip 1 that the utility model provides comprise one from the centre outside four broken tire spine objects of radial even distribution, spine 11 is triangular pyramid shape from the tip to the root, cone angle is 30 degree, on the conical surface between two adjacent awl ribs, convex with fin 12, form air discharge duct 13 in the both sides of fin.

For the suitable tire that punctures all size vehicle, when three spines supported ground, the thorn of the 4th spine 12 up point was the 50-70 millimeter to the height h on ground.

Mid portion at this tire burster 1 is provided with perforation 2, wears rope therein, several these tire bursters is coupled together form the tire burster chain.

Claims

1, a kind of tyre spiked device with three-edge and four-tip, it is characterized in that: comprise one from the centre the outside object of four broken tire spines of radial even distribution, described spine is triangular pyramid shape from the tip to the root, cone angle is the 25-35 degree, on the conical surface between two adjacent awl ribs, convex with fin, form air discharge duct in the both sides of fin.

2, tire burster according to claim 1 is characterized in that: when three described spines supported ground, the thorn point of the 4th described spine up was the 50-70 millimeter to the height on ground.

3, tire burster according to claim 1 is characterized in that: the cone angle of the triangular pyramid of described spine from the tip to the root is 30 degree; When three described spines supported ground, the thorn point of the 4th described spine up was 60 millimeters to the height on ground.

4, according to claim 1 or 2 or 3 described tire bursters, it is characterized in that: the mid portion at described object is provided with perforation, wears rope therein.
