Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic machinery, in particular to a double-continuous portable high-strength pneumatic capture net. Background Art

[0002] At present, the arrest nets used by public security departments to arrest criminals are mostly gun-type gunpowder nets. The net gun uses gunpowder as power, and there is a certain risk of gunpowder exploding in the barrel, resulting in the net being unable to be fired. It will also cause harm to public security personnel and delay the opportunity of arrest.

[0003] Moreover, the existing pneumatic capture net can only launch one capture net at a time during launch. If the capture is unsuccessful, it cannot be launched again, resulting in a low hit rate of the launch. In addition, most of the existing pneumatic capture nets are of integrated design. After launching once, the pneumatic capture net needs to be replaced as a whole, which increases the cost of use. Since the pneumatic capture net is usually a closed structure and is not easy to disassemble, particulate matter will accumulate in the net, affecting the capture efficiency. The interior of the pneumatic capture net is relatively narrow, making cleaning and maintenance more difficult, thereby increasing the cost of use and workload. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a double-continuous portable high-strength pneumatic capture net.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0012] Preferably, the outer wall of the cylinder is provided with a buffer and anti-slip pad.

[0013] The beneficial effects of the utility model are:

[0014] The pneumatic capture net uses micro high-pressure gas bombs to replace traditional gunpowder launches, which is light and easy to carry. It uses two separate high-pressure gas storage chambers, and the two high-pressure gas storage chambers are independent and not connected. By pressing a button, the high-pressure gas can be released from each chamber one by one, which solves the problem of only being able to launch one capture net at a time.

The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0027] Example:

[0028] Reference Figure 1-5 A double-shot portable high-strength pneumatic capture net comprises a cylinder 1, the end of the cylinder 1 is connected to a net cover launch part 3 through a connecting part 2, an end cover 4 is arranged at one end of the cylinder 1 away from the connecting part 2, an installation groove is arranged at the inner bottom of the end cover 4, and a launch gas cylinder 5 is arranged in the installation groove;

[0029] Two high-pressure gas storage bins 6 are symmetrically provided inside the cylinder 1. The two high-pressure gas storage bins 6 are independent of each other and are not connected. Two shaft sleeves 7 are fixedly connected in the mounting groove of the end cover 4. A connecting rod 8 is provided inside the shaft sleeve 7. A cleaning brush 9 is provided on the outer surface of the connecting rod 8. The connecting rod 8 and the shaft sleeve 7 are a detachable structure.

[0030] A spring 10 is provided on one side of the high-pressure gas storage bin 6 close to the launch gas cylinder 5 , one end of the spring 10 is connected to a ejector pin 11 , and one end of the ejector pin 11 abuts against the bottleneck of the launch gas cylinder 5 .

[0031] Two launching channels 12 are symmetrically provided inside the mesh launch part 3, and the two launching channels 12 are respectively connected to the two high-pressure gas storage bins 6. A capturing net 13 is arranged between the high-pressure gas storage bins 6 and the launching channels 12, and a traction head is connected around the capturing net 13, and a rubber sleeve air bag is connected to the traction head.

[0032] Two push buttons 14 are symmetrically arranged on the outer wall of the cylinder 1 , and a plurality of drainage holes 15 are opened on the lower side of the push buttons 14 and on the outer wall of the cylinder 1 , and the drainage holes 15 are filled with sealing plugs.

[0033] The bottleneck of the launch gas cylinder 5 is filled with a sealing member, and a sealing sheet is provided at the connection between the high-pressure gas storage bin 6 and the launch channel 12 .

[0034] The outer wall of the cylinder 1 is provided with a buffer anti-skid pad 16 .

[0035] In the present embodiment, when it is necessary to use the pneumatic capture net for capture, the cylinder 1 is held by hand, and then a button 14 is pressed. When the button 14 moves downward, the spring 10 is squeezed. When the spring 10 is squeezed, the ejector pin 11 is pushed to one side. The ejector pin 11 moves in the direction of the launch cylinder 5 and gradually pierces the seal at the bottleneck of the launch cylinder 5. Then, the nitrogen dioxide gas is rapidly released from the launch cylinder 5. After the release, the nitrogen dioxide gas fills the inside of the high-pressure gas storage bin 6, and then it rapidly expands in the closed and narrow space to generate a high pressure of more than 30 MPA. Then, the kinetic energy of the high-pressure gas breaks the sealing sheet at the high-pressure gas storage bin 6, and is instantly released from the high-pressure gas storage bin 6, and is ejected through the launch channel 12. The compressed air pushes the capture net 13 to the outside of the net cover launching part 3, and the capture net 13 is opened in the air. When the capture net 13 is opened in the air, the rubber sleeve air bags at the traction heads around it cushion the capture net 13, so that even if the capture net 13 accidentally hits the human body during the high-speed driving process, it will not cause any harm to the human body, thereby achieving the effect of rapid capture. If the capture is unsuccessful, the second button 14 is pressed again, and the above operation is repeated, so that the capture net 13 can be launched twice in succession, thereby improving the hit rate of the launch and ensuring the success rate of the capture task. The buffer anti-slip pad 16 can absorb part of the recoil generated by the high-pressure gas launch, thereby reducing the impact of the pneumatic capture net on the user during the launch process.

[0036] After the use is completed, the end cover 4 on one side of the cylinder body 1 can be twisted to disassemble the end cover 4, and then the launching gas cylinder 5 in the end cover 4 can be removed for replacement, and then the connecting rod 8 can be sleeved into the shaft sleeve 7, and the other end of the connecting rod 8 can be extended into the high-pressure gas storage bin 6, and then the end cover 4 can be installed on one side of the cylinder body 1. At this time, the buffer anti-skid pad 16 is removed, and the sealing plug in the drainage hole 15 is taken out, and then the end cover 4 is rotated. When the end cover 4 rotates, the connecting rod 8 is driven to rotate, and when the connecting rod 8 rotates, the cleaning brush 9 is driven to rotate, so that when the cleaning brush 9 rotates along the inner wall of the high-pressure gas storage bin 6, the particles and impurities adhered to the inside of the high-pressure gas storage bin 6 can be cleaned, and the cleaned particles and impurities are discharged through the drainage hole 15. After the cleaning is completed, the connecting rod 8 is taken out from the shaft sleeve 7, and a new launching gas cylinder 5 is installed for the next use. The whole process of disassembly and assembly is convenient, which improves the use efficiency of the pneumatic capture net.
