Description

Net bomb catching device
Technical Field
The invention relates to the field of security protection, in particular to a net bomb capturing device.
Background
In the security field, when a public police catches a criminal, in the process of pursuing, particularly in the process of escaping from a gangster, the public police is not convenient for driving a gun but cannot allow the gangster to escape. In addition, the scoundrel cannot close up and the scoundrel may carry a sharp weapon or even a fatal weapon such as a gun. If the police arrest is happened, the life safety of the police is possibly endangered. Therefore, a non-lethal weapon device capable of realizing non-contact capture in a certain range is needed for equipping police force.
Currently, many researches and inventions aiming at the requirement have been made, and the main equipment is a net-bullet type launching device. Some of these devices take the form of high pressure gas bombs that eject the net by compressed gas. The apparatus generally includes a launch net head for loading the net; the tail part is provided with a gas cylinder for containing high-pressure gas, and the middle part is provided with a connecting piece for connecting the head part and the tail part. This device basically meets the requirements with regard to emission effect, but at the same time has a number of disadvantages. Among them, the most serious is the low safety factor of the high-pressure gas cylinder itself. The device is in a high-pressure state when the pursuit task is not executed, and is easy to cause other injuries. In addition, the device needs to replace the whole high-pressure gas cylinder after being used, and only one gas cylinder can be shot, so that a user needs to carry a plurality of gas cylinders in the practical application process to ensure that no other situations occur.
In addition, the powder can be used. The device is basically the same as the former, but slightly changed in the tail bin. The weight of the device can be reduced by adopting the form of gunpowder, but the gunpowder is not suitable for the general security field. Firstly, the limitation of gunpowder management reduces the maneuverability of manufacturing corresponding gunpowder equipment; besides, many factors such as powder regulation and limitation need to be considered in the production process, so that the application of general security equipment is difficult.
For example: the Chinese patent with the application number of CN201920890923.7 found by retrieval discloses an externally-hung net bomb catcher based on a 92G type pistol, which comprises a net bomb and a net bomb launcher; the net bomb comprises a catching net, rubber bombs and connecting ropes; the net bullet emitter comprises a conical tube body and a gun joint arranged at the small end of the conical tube body, wherein a net loading cavity is arranged in the middle of the conical tube body, and a plurality of air passages arranged along the circumferential direction of the conical tube body are also arranged on the conical tube body; the gun connector comprises a connector body, a gun head jack arranged on the connector body, an airflow discharge hole arranged at the front end of the gun connector body, and a locking clamp inserted at the bottom of the connector body. However, the above patents have the following disadvantages: firstly, structurally, although the air passage is prolonged, the traction object rubber bomb is arranged at the air passage opening, the length effect of the air passage cannot be utilized to the maximum extent by the traction object rubber bomb, and therefore higher initial speed cannot be emitted; secondly, the connection structure has unstable risk, and because the connection with the 92-type pistol is directly selected, special treatment is not carried out on the interface of the net bin and the pistol, and the net bin and the pistol are fixed only by a single-side latch, so that the problems of certain damage and infirm are solved. In addition, the device utilizes the airflow generated by the empty-packed cartridge to realize the launching, the principle of the device is similar to that of a gunpowder type launching device, and the empty-packed cartridge has corresponding dosage standards, so that the dosage of the gunpowder is difficult to be adjusted individually, and the launching at a specific distance is difficult to achieve.

Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that variations and modifications can be made by persons skilled in the art without departing from the spirit of the invention. All falling within the scope of the present invention.
Referring to fig. 1, a net bullet catching device according to a preferred embodiment of the present invention includes a net bullet 2 and a net bullet launcher.
Referring to fig. 2, the net bomb 2 includes a net structure 22 with a traction weight 21 at the edge; the traction weight 21 can be connected to the net structure 22 through a line. When the net bomb 2 is launched, the net structure 22 can net the entire body of the gangster, so that the gangster cannot move in a short time, thereby capturing the gangster.
The net bullet launcher comprises a net bin and a pneumatic power device;
the net cabin is a circular truncated cone-shaped structure 1 with a hollow accommodating chamber. As a preferred mode, the net cabin is a thin-wall type round table-shaped structure 1. The hollow accommodating chamber of the round table-shaped structure 1 is used for storing the reticular structure 22, and the large end part of the hollow accommodating chamber is open; the inner wall of the hollow accommodating chamber is provided with a pipeline 12 which is used for accommodating the traction heavy hammer 21 and providing a launching channel for the traction heavy hammer along the axial direction, and the pipeline 12 enables the large end part and the small end part of the hollow accommodating chamber to be communicated, namely two ends of the pipeline 12 can be communicated with the external environment; the number of pipes 12 matches the number of traction weights 21. The pipe 12 has a certain length, and the length is greater than the length of the traction weight 21; the big end part of the hollow accommodating chamber is provided with a fixing device 4 for limiting the movement of the traction heavy hammer 21, so that the traction heavy hammer 21 is fixed in the pipeline 12; in the implementation process, a plurality of traction weights 21 are respectively placed into the corresponding pipes 12 and installed at one end of the pipe 12 close to the small end of the hollow accommodating chamber, the net-shaped structure 22 except the traction weights 21 is placed into the hollow accommodating chamber, and then the traction weights 21 are fixed in the pipe 12 by the fixing device 4.
The gas power device can store combustible gas and can generate high-pressure gas through expansion after the combustible gas is combusted; the gas power device is connected with the small end part of the hollow accommodating cavity, the gas outlet of the gas power device is communicated with one end of the pipeline 12, high-pressure gas is injected into the pipeline 12 through the gas power device, the traction heavy hammer 21 is pushed to move outwards along the channel, and therefore the net bomb 2 is emitted to a specified position from the large end part (the large end part is an emitting end) of the hollow accommodating cavity.
The working principle of the net bomb catching device is greatly different from that of the traditional net bomb launching device, and the device in the embodiment mainly releases energy based on the combustion of combustible gas (such as hydrocarbon) to push the net bomb 2 to launch; when the gas power device is filled with combustible gas (for example, butane) with a proper concentration, after the combustible gas is ignited, the combustible gas is rapidly combusted, and the volume of the combustible gas rapidly expands to generate high-pressure gas, and the high-pressure gas pushes the traction weight 21 in the pipeline 12, so that the traction weight 21 is forced to generate a great acceleration to fly out. And the net bullet catching device makes the length of the pipeline 12 inconsistent with the length of the heavy hammer, thereby prolonging the length of the pipeline 12. For this reason, the traction weight 21 will be forced continuously for a while when the traction weight 21 is not completely separated from the launching tube 12. Therefore, the traction weight 21 is continuously stressed; in contrast, the initial velocity of the traction weight 21 when leaving the device is much higher than the initial velocity of the structural design in which the traction weight 21 is flush with the end face, so that the launching effect is much better.
