technical background

Firing devices such as bows and crossbows use the principle of elastic potential energy of materials. By combining the strength of human beings and the elasticity of objects, the arrowheads can be shot far away, so as to achieve the purpose of killing the target. The utility model of bows and crossbows is a great progress of human technology, which shows that people already know how to use the energy stored in machinery: when people pull the string hard to force the bow body to deform, they store their own energy in it; The body quickly returned to its original shape, and at the same time violently released the stored energy, and then powerfully ejected the arrow on the string.

The lethality of traditional arrows is not enough. When hunting wild boars and other thick-skinned animals invading human residences and animal farmland, or hunting large animals, traditional bows and arrows may not be able to do what they want. Therefore, there is an urgent need in the art for improved bows or crossbows.

detailed description

The utility model provides a secondary killing arrow device, which includes a first arrow body and a second arrow body, the first arrow body is a hollow structure, and the second arrow body is located on the hollow structure and can slide in it.

In the present invention, the front end of the first arrow body may be made of breakable material, and when the secondary killing arrow device hits the target, the second arrow body slides forward and breaks through the front end of the first arrow body issued from breakable materials. The front end of the breakable material is to reduce the flight resistance of the first rocket body. At the same time, the less impact the breakable material has on the kinetic energy of the second rocket body, the better. For example, the front end of the first rocket body may be a breakable material spoiler.

In one embodiment of the present invention, an arrow is weakly connected to the front end of the first arrow body, and when the secondary killing arrow device hits a target, the second arrow body slides forward to drive the arrow together Issued a second blow.

In the present invention, the front end of the second arrow body may be a hard inverted cone.

In the present invention, the second arrow body is preferably weakly connected to the rear end of the hollow structure of the first arrow body before launching, and when the secondary killing arrow device hits the target, the second arrow body sliding forward along the hollow structure of the first rocket body. When launching, if the second arrow body is not at the rear end of the hollow structure of the first arrow body, it may generate an impact force backwards and impact the rear end of the first arrow body, which will not only weaken the effect, and it is possible to break through the rear end of the first arrow body, causing damage.

In the present utility model, an elastic mechanism may be provided at the rear end of the hollow tube of the first arrow body, and the second arrow body is weakly connected to the elastic mechanism before launching. During firing, the elastic mechanism, such as a spring, can accumulate potential energy, so that when the secondary destruction arrow device hits a target, the potential energy forms an additional driving force on the second arrow body.

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Fig. 1 shows a secondary killing arrow device 100 according to an embodiment of the present invention, comprising a first arrow body 101 and a second arrow body 102, the first arrow body 101 is a hollow structure, and the second arrow body 102 is located at the In the above-mentioned hollow structure, the second rocket body 102 can move relatively in the structure of the first rocket body 101, and the rear end of the hollow tube of the first rocket body 101 is provided with an elastic device 104. Before launching, the second rocket body 102 and the weak Connected to the elastic device 104.

As shown in the figure, the front end of the first arrow body 101 is a breakable material spoiler 105, and the front end of the second arrow body 102 is connected with an arrow 103, and the first arrow body 101 and the second arrow body 102 obtain kinetic energy to move forward at the same time. When hitting the target, according to the principles of physics, the speed of the first rocket body 101 suddenly decreases or stops suddenly, while the second rocket body 102, which is relatively independent of the structure of the first rocket body 101, breaks away from the elastic device 104 due to the inertial force and continues to Move forward at a certain speed and shoot out.

Fig. 2 shows a secondary killing arrow device 200 according to another embodiment of the present invention, comprising a first arrow body 201 and a second arrow body 202, the first arrow body 201 is a hollow structure, and the second arrow body 202 is located at In the hollow structure, the second arrow body 202 can move relatively in the structure of the first arrow body 201. As shown in the figure, the rear end of the hollow tube of the first arrow body 201 is provided with an elastic device 204. The two rocket bodies 202 are weakly connected to the elastic device 204 .

The front end of the first arrow body 201 is connected with an arrow 203 through a weak connection device 206. When the secondary killing arrow device hits the target, the second arrow body 202 is separated from the elastic device 204 and slides forward to drive the arrow 203 Issued together to produce a second blow.

It must be noted that, in addition to the above-mentioned embodiments, the utility model also has other implementation modes. It can be seen that the relevant equivalent replacement technical solutions should all fall within the scope of protection required by the utility model.
