Description

explosion arrow

technical field

The invention belongs to an arrow, in particular to an explosive arrow.

Background technique

With the development of outdoor recreational sports, such as bow and arrow shooting, various types of arrows appear thereupon. The general arrows are all made of a single metal body. After hitting the target, they can only be fixed in the target or penetrate the target according to the physical characteristics of the target; as a game, the viewing effect is not intuitive enough; as a wild hunting, a simple Puncture damage also has a limited effect on the mobility of prey.

In order to enhance the destructive and penetrating capabilities, it is generally necessary to increase the rotation of the arrow body, or simply increase the weight of the arrow. However, in order to achieve a balance, the shape and length of the arrow body need to be redesigned in accordance with the shift of the center of gravity, otherwise the shooting distance must be affected.

In order not to simply increase the weight of the arrow or change the shape of the arrow for the purpose of increasing the destructive power, which will increase the difficulty of developing the arrow body, one of the better solutions is: without greatly changing the arrow body, After the arrow hits the target, a special switch is triggered, and the arrow can expand rapidly. Another similar application is dummies. However, if it is like using dummies, it will cause waste of arrows that cannot be reused, and it will increase the difficulty of cleaning.

Contents of the invention

The object of the present invention is to provide a gas explosion arrow capable of solving at least one of the above-mentioned problems.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

Refer to Fig. 1 ~ Fig. 2. Explosion arrow, including body 1, air nozzle 2 and connecting rod 3, body 1 is provided with air storage bin 11, gas nozzle 2 gas nozzles are conical, connecting rod 3 is located at the tail end of air nozzle 2, connecting rod 3 can Inserted into the gas storage bin 11, the connecting rod 3 can move relative to the gas storage bin 11. The connecting rod 3 is provided with a communication hole 31, and the air nozzle 2 is provided with an air outlet hole 21. The communication hole 31 communicates with the air outlet hole 21, and the communication hole 31 can communicate with the gas storage bin 11.

In actual use, a plurality of air outlet holes 21 can be provided around the air nozzle 2, so that the compressed gas in the gas storage chamber 11 can be released to the surroundings of the air nozzle 2, which can accelerate the rotation of the arrow and increase the destructive power of the arrow. Meet the corresponding use effect. In order to facilitate the fixing of the connecting rod 3 and the air nozzle 2, an installation hole is provided at the tail end of the air nozzle 2, and the connecting rod 3 is inserted into the installation hole for fixing, and the communication hole 31 on the connecting rod 3 communicates with the air outlet 21 .

The front end of the gas storage bin 11 is provided with an end cover 4 , and the connecting rod 3 extends into the gas storage bin 11 after passing through the end cover 4 . Wherein, the end cap 4 and the front end of the body 1 are screwed and fixed, which ensures the stability of the cooperation between the end cap 4 and the body 1 .

The tail end of the gas storage bin 11 is provided with a tail rod 12 , and the tail rod 12 is provided with an air inlet 121 , which can communicate with the gas storage bin 11 after passing through the tail rod 12 . Wherein, the tail rod 12 and the body 1 are integrally formed; the gas storage chamber 11 can be inflated through the air inlet 121 .

The explosion arrow of the present invention also includes a sealing ball 5, the tail rod 12 is provided with an accommodation chamber 122, the sealing ball 5 is arranged in the accommodation chamber 122, and the air inlet 121 communicates with the gas storage bin 11 through the accommodation chamber 122 One end of the air inlet 121 communicating with the accommodating cavity 122 is provided with a tapered hole 123, the sealing ball 5 can fit the side wall of the tapered hole 123, and the outer diameter of the sealing ball 5 is larger than the maximum of the tapered hole 123. aperture. Therefore, when the gas storage bin 11 is inflated, under the action of air pressure, the sealing ball 5 is pushed close to the tapered hole 123, so that the accommodating chamber 122 and the air inlet hole 121 are in a disconnected state, preventing the gas storage bin 11 from The gas is discharged from the air inlet 121. Therefore, the sealing ball 5 acts as a one-way valve, so that the gas can only flow in one direction; the sealing ball 5 can be a steel ball or a rubber ball, which can be selected according to different requirements.

The gas explosion arrow of the present invention also includes a gland 6, the gland 6 is set on the end face of the accommodating cavity 122, the gland 6 is located between the gas storage bin 11 and the sealing ball 5, and the gland 6 is provided with a straight hole 61 , the accommodating cavity 122 communicates with the gas storage bin 11 through the straight hole 61 . The gland 6 and the accommodating cavity 122 adopt an interference fit, so that the gland 6 is fixed at one end of the accommodating cavity 122 , thereby ensuring that the sealing ball 5 is always kept in the accommodating cavity 122 .

The explosion arrow also includes a first sealing ring 7 , the first sealing ring 7 is sleeved on the end cover 4 , and the first sealing ring 7 is located at the joint between the end cover 4 and the body 1 .

The explosion arrow also includes a second sealing ring 8, the connecting rod 3 is T-shaped, the large end of the connecting rod 3 is located in the gas storage bin 11, the outer circumference of the connecting rod 3 is provided with a mounting groove, and the second sealing ring 8 is set in the mounting groove Above, the end cover 4 is provided with a mounting hole, the small end of the connecting rod 3 passes through the mounting hole and is connected to the air nozzle 2, and the second sealing ring 8 can be matched with the mounting hole. Wherein, the outer diameter of the second sealing ring 8 is consistent with the diameter of the mounting hole on the connecting rod 3, so that the second sealing ring 8 can play a sealing role when mated with the mounting hole.

When the gas explosion arrow of the present invention is in use, gas is first charged into the gas storage chamber 11 through the air inlet 121 on the tail rod 12, and gas or powder of a corresponding color can be charged according to actual needs. After the gas storage bin 11 is inflated, the gas in the gas storage bin 11 is in a compressed state. When the explosion arrow shoots out and hits the target or the corresponding target, under the impact force, the air nozzle 2 pushes the connecting rod 3 Move inside the gas storage bin 11, so that the communication hole 31 on the connecting rod 3 moves into the gas storage bin 11, realizing the communication among the gas storage bin 11, the communication hole 31 and the air outlet hole 21. At this time, the gas storage bin The compressed gas in 11 is released instantly, and the target or prey inserted by the arrow expands rapidly from the inside. At the same time, the jet of the arrow makes the arrow accelerate the rotation and enhance the destructive power. Quickly observe the location of the hit, easy to find and track. In actual use, the shape of the air outlet 21 can be changed so that when the gas is released, a specific sound is emitted, which is used to scare off outdoor wild animals or facilitate finding targets.

The explosive gas arrow can be directly pulled out from the target, is easy to take out, can be reused, reduces waste of resources, and saves resources; and compared with the existing arrows that cause damage due to ejected fragments, it is very easy to clean and more environmentally friendly.

The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, without departing from the inventive concept of the present invention, some modifications and improvements can also be made, and these all belong to the present invention. protection scope of the invention.
