[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] It should be noted that when an assembly is referred to as being "connected" to another assembly, it can be directly connected to the other assembly or there can be a middle assembly. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0028] As shown in the drawings, Figures 1-6 A quick reset firing device includes a pull ring 11, a firing magazine 12, a limiting unit 14, a first spring 16, a pull rod 17 and a striker 18. One end of the firing magazine 12 is rotationally and clippably connected to the pull ring 11. The first spring 16, the pull rod 17 and the striker 18 are all built-in in the firing magazine 12. One end of the pull rod 17 is connected to the pull ring 11. Two ends of the first spring 16 abut against the firing magazine 12 and the striker 18 respectively. The striker 18 is axially moved and limited through the pull rod 17. The striker 18 has a pointed end away from the first spring 16. The striker 18 is further provided with a limiting groove 181. The limiting unit 14 is connected to the firing magazine 12. After the pull ring 11 is rotationally separated from the firing magazine 12, the limiting unit 14 is cooperatively limited with the limiting groove 181 through external pulling. After the pull ring 11 is pushed back, the firing magazine 12 is rotationally clippable to complete chambering. When the limiting unit 14 is separated from the limiting groove 181, the striker 18 is fired.

[0029] The device comprises a pull ring 11, a firing chamber 12, a limiting unit 14, a first spring 16, a pull rod 17 and a striker 18. The pull rod 17 can be of any shape, and the pull ring 11 is provided with notches for limiting the rotation of the pull rod 17. One end of the pull rod 17 is matched with the corresponding notch and is fixed by a screw. The pull ring 11 can rotate relative to the firing chamber 12, such as being assembled and separated by rotating clamping. The extension and contraction of the first spring 16 and the sliding of the striker 18 in the firing chamber 12 are mainly driven by the pull ring 11. For example, one end of the pull rod 17 is provided with a limiting hook, which limits the striker 18. One end of the first spring 16 is in contact with the striker 18, and the other end is in contact with the side of the firing chamber 12 close to the pull ring 11. A sliding limiting space is formed in the firing chamber 12, so that the pull ring 11 can compress or release the first spring 16 and change the position of the striker 18 while reciprocating. After the pull ring 11 is rotated and separated from the firing chamber 12, the limiting unit 14 is matched and limited with the limiting groove 181 by external pulling, and is rotated and clamped with the firing chamber 12 after the pull ring 11 is pushed back to complete the chamber loading. At this time, the position of the striker 18 is fixed, the limiting unit 14 is connected with the firing chamber 12 and releases the striker 18 when it is separated from the limiting groove 181 to complete the firing. The limiting groove 181 of the striker 18 can be a coaxially arranged annular groove.

[0030] In an embodiment, at least one first avoiding groove is further provided on one end of the firing chamber 12 close to the pull ring 11, and the first avoiding groove is sealed when the firing chamber 12 and the pull ring 11 are rotationally clamped and connected, and is communicated with the outside when the firing chamber 12 and the pull ring 11 are rotationally separated.

[0031] It should be noted that the existing firing device lacks safety in the state of waiting to fire.

However, when the firing device of the present application is in the state of waiting to fire after the installation of the launching unit 2, the launching unit 2 comprises a gas cylinder and a launching head, etc. The launching head can be used to emit a capture net, tear gas, etc. At this time, the pull ring 11 is not clamped relative to the firing chamber 12, and a closed space (such as the first avoiding groove being communicated with the outside) cannot be formed in the firing chamber 12. In the case of misoperation, the gas leaks from the direction of the pull ring 11, and the launching unit 2 is not subjected to sufficient gas pressure to cause the launching head to emit. After confirming that it is ready to use, the pull ring 11 and the firing chamber 12 are clamped tightly, so that a closed space is formed in the firing chamber 12. At this time, the striker 18 is fired, and the gas in the gas cylinder is released instantaneously to generate high-pressure gas in the firing chamber 12, so as to launch the launching head. The gas cylinder can be a carbon dioxide cylinder, etc.

[0033] Wherein, the front gland 121 and the barrel 122 are connected by screws, the front pressing sheet 15 and the firing cartridge 12 are fixed by screws, and a sliding limiting space is formed in the firing cartridge 12, so that the two ends of the first spring 16 abut against the front pressing sheet 15 and the striker 18 respectively, the pull ring 11 drives the pull rod 17 to reciprocate and cannot be separated from the firing cartridge 12.

[0034] In an embodiment, a plurality of first avoiding grooves are provided on the front pressing sheet 15, and the arc-shaped sliding seats are correspondingly provided in the first avoiding grooves and have gaps with the first avoiding grooves.

[0035] Wherein, the plurality of first avoiding grooves provided on the front pressing sheet 15 and the arc-shaped sliding seats correspondingly gap cooperate, so that when the pull ring 11 is not buckled with the firing cartridge 12, the firing cartridge 12 and the gas cylinder cartridge 13 cannot form a closed space, avoiding the danger caused by misoperation, and being beneficial to improve the safety. Preferably, the pull rod 17 includes two symmetrically arranged arc-shaped sliding seats, and the area of the first avoiding groove is greater than the cross-sectional area of the sliding part of the arc-shaped sliding seat.

[0036] In an embodiment, the pull ring 11 is coaxially provided with a first annular boss 11a, and the barrel 122 is provided with a first sealing groove 122b in sealing cooperation with the first annular boss 11a.

[0037] Wherein, the first annular boss 11a of the pull ring 11 cooperates with the first sealing groove 122b of the firing cartridge 12 for limiting, and a sealing ring is arranged, such as the sealing ring is arranged in the corresponding first sealing groove 122b to improve the sealing performance.

[0038] In an embodiment, the inner wall of the barrel 122 is further provided with two second avoiding grooves 122c parallel to the axis, and the arc-shaped sliding seats are correspondingly arranged in the second avoiding grooves 122c and are limited in rotation around the axis direction through the second avoiding grooves 122c.

[0039] Wherein, the pull rod 17 cooperates with the two second avoiding grooves 122c in the firing cartridge 12 for limiting, so that the pull ring 11 drives the arc-shaped sliding seat to rotate only in the range of the second avoiding groove 122c in the firing cartridge 12, which is beneficial to fast reset.

[0040] In an embodiment, the limiting unit 14 comprises a motor and a limiting assembly, the motor is connected with the firing chamber 12 and used to drive the limiting assembly to disengage from the limiting groove 181 to complete the firing of the striker 18. The firing operation is completed by electricity, which is beneficial to realize remote firing.

[0041] In an embodiment, the motor of the limiting unit 14 is a rudder 142 with a rudder arm 143, and the limiting assembly comprises a first fixed seat 141, a limiting block 144, a limiting slide rod 145, a second spring 146 and a first limiting seat 147.

The limiting block 144 is limited by the second spring 146 when the pull ring 11 is pulled out, or the firing is completed after the rudder arm 143 drives the first limiting table 145a to disengage from the limiting groove 181.

[0042] Among them, the first fixed seat 141 is fixed on the firing chamber 12 by screws, a cylindrical hole coaxial with the guide hole 122a of the firing chamber 12 is formed on the first fixed seat 141, the limiting slide rod 145 is installed in the cylindrical hole of the first fixed seat 141 for up and down sliding, one end of the limiting slide rod 145 is in threaded connection with the limiting block 144, and the other end of the limiting slide rod 145 abuts against the second spring 146 in the first limiting seat 147, so that the limiting slide rod 145 is in a compressed state. The limiting slide rod 145 can only reciprocate up and down in the cylindrical hole of the first fixed seat 141 to realize the cooperation or disengagement with the striker 18. It is easy to understand that a sealing ring can be further arranged on the firing chamber 12, which is beneficial to ensure the sealing performance during the movement of the limiting block 144.

[0043] In an embodiment, the quick reset firing device further comprises a wireless communication module and a remote controller, and the remote controller sends a driving signal to the motor through the wireless communication module.

[0044] Among them, the instructions sent by the remote controller are sent to the quick reset firing device 1 through the wireless communication module to drive the motor (such as the rudder 142) to complete the firing action, which can be carried on the unmanned aerial vehicle and other equipment to realize remote control firing. The wireless communication module can be an ELRS 2.4G wireless communication module.

[0045] In an embodiment, the quick reset firing device further comprises a gas cylinder compartment 13 connected to the other end of the firing compartment 12 and used for detachable connection with the launching unit 2, the launching unit 2 comprising a gas cylinder and a launching head arranged in sequence in the direction away from the striker 18, the tip of the striker 18 facing the gas cylinder compartment 13 and generating high-pressure gas by piercing the gas cylinder through the firing of the striker 18 to complete the launching of the launching head.

[0046] As shown in Figure 6 the end of the gas cylinder compartment 13 away from the firing compartment 12 is threaded for connection with the launching unit 2, such as direct or indirect connection with the gas cylinder, so that in the state to be fired, the firing compartment 12 and the gas cylinder compartment 13 form a sealed cavity, and when the striker 18 pierces the gas cylinder, the gas is released instantaneously in the sealed cavity to form a high-pressure and low-temperature environment. The launching unit 2 includes a gas cylinder and a launching head, etc., and the launching head can be used to launch a capture net, tear gas, etc. When containing a capture net, a plurality of first through holes can be provided on the launching head and communicated with the sealed cavity, and the first through holes are preferably evenly distributed in a ring shape and the axis is inclined relative to the axis of the launching head, i.e. in a trumpet shape.

When the sealed cavity is filled with high-pressure gas, the net hammers are pushed out, and the inclination angle of the first through holes can be set according to the size of the net, so that different specifications of the net are fully opened at a specified distance when launched. It is easy to understand that when other objects such as tear gas need to be launched, simple adaptive modification of the launching head structure can be realized.

On the other hand, the firing operation is completed by electricity, which is conducive to remote firing. And it can be detachably connected with the launching unit 2, such as threaded connection or clamping, which can realize quick replacement and fast response. In addition, the pneumatic design is more safe and reliable, and has good concealment and stability.

[0048] Working principle:

[0049] When the pull ring 11 is pulled out of the firing chamber 12, the pull rod 17 is moved, the striker 18 slides out of the firing chamber 12 under the limiting action of the pull rod 17, and the first spring 16 is compressed. When the striker 18 moves out of the firing chamber 12, the limiting slide rod 145 is pressed into the limiting groove 181 of the striker 18 due to the action of the second spring 146 in the first limiting seat 147, and then the pull ring 11 is pushed back to rotate and engage with the firing chamber 12 to complete the charging. At this time, the striker 18 is limited in the standby firing state, the limiting slide rod 145 has a first limiting table 145a, the rudder 142 is fixedly installed on the first fixed seat 141 through a screw, the rudder arm 143 is fixedly connected to the rudder 142, and when the rudder 142 receives an instruction, it will drive the rudder arm 143 to rotate. The rotation of the rudder arm 143 will contact the first limiting table 145a of the limiting slide rod 145, so that the limiting slide rod 145 moves to the end where the first limiting seat 147 is located. At this time, the first spring 16 in the firing chamber 12 is released to generate a pushing force, which pushes the striker 18 along the inside of the firing chamber 12 to the limiting position of the pull rod 17. A part of the tip of the striker 18 can extend into the gas cylinder chamber 13 to pierce the gas cylinder. When the striker 18 pierces the gas cylinder, the gas is released in the gas cylinder chamber 13 to form a high-pressure and low-temperature environment to complete the launching of the launching head to launch the capture net or tear gas. After the firing action is completed, the launching unit 2 can be quickly replaced for the next firing preparation.

The first fixed base (141) is connected to the firing chamber (12). The servo motor (142) and the first limiting seat (147) are both connected to the first fixed base (141). The second spring (146) is built into the first limiting seat (147) and its two ends abut against the first limiting seat (147) and the limiting slide rod (145) respectively. The limiting slide rod (145) is connected to the first fixed base (141). A fixed base (141) is slidably connected to and vertically connected to a first limiting platform (145a). The limiting block (144) is connected to one end of the limiting slide rod (145) near the firing chamber (12). The firing chamber (12) is also provided with a guide hole (122a) for avoiding the limiting block (144). When the pull ring (11) is pulled outward, the limiting block (144) cooperates with the limiting groove (181) for limiting under the elastic force of the second spring (146), or the firing is completed after the servo motor (142) drives the rudder arm (143) to push the first limiting platform (145a) away from the limiting groove (181).

9. The quick-reset firing device as described in claim 7 or 8, characterized in that: The quick-reset firing device also includes a wireless communication module and a remote controller, the remote controller sending a drive signal to the motor through the wireless communication module.

10. The quick-reset firing device as described in claim 1, characterized in that: The quick-reset firing device also includes a gas cylinder chamber (13), which is connected to the other end of the firing chamber (12) and is used to detachably connect to the firing unit (2). The firing unit (2) includes a gas cylinder and a firing head arranged sequentially in a direction away from the firing pin (18). The tip of the firing pin (18) faces the gas cylinder chamber (13) and the firing of the firing pin (18) punctures the gas cylinder to generate high-pressure gas to complete the firing of the firing head.
