DETAILED DESCRIPTION

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0029] Embodiment one: Referring to Figure 18 , when the firing device and the gas cylinder are assembled, the striker is directly opposite the gas cylinder port, the striker, the bearing mechanism of the striker, and the locking mechanism of the loading are on the same side, and there is a certain weight. When the gas cylinder is pierced by the striker, the gas flows out of the gas cylinder, and a certain gas power is needed to push the striker open to enter the gas chamber, which causes a large discount of the initial gas power. Or referring to Figure 19 , although the firing device is designed to not hinder the flow of gas, the optimized device gas passage is too complex, which is not conducive to the propagation of gas. In addition, in the traditional firing device, the striker, the bearing mechanism of the striker, and the locking mechanism of the loading are on the same side in series, and when the gas cylinder is assembled, it is directly opposite the gas cylinder port. This combination of the firing device increases the size of the firing device, greatly reducing the portability of the firing device. Moreover, the commonly used firing device on the market needs to disassemble multiple components in sequence after firing to achieve the replacement of a new gas cylinder and a new copper sheet, and to achieve a new round of loading and stringing. The whole process is relatively complex.

[0030] The present application is an easy-to-operate portable firing device that specifically solves the above problems, which will be described in detail in conjunction with embodiment one.

[0031] In conjunction with Figures 1-3 , the present embodiment provides an easy-to-operate portable firing device, which comprises a launching assembly 1 and a firing assembly 2, and the two are connected through threads.

[0032] Referring to Figure 6The launching assembly 1 comprises a clasp 11, a launching head 12, a mounting seat 13, a baffle 14, a weight 15, a net hammer 16, a net holder 17, a copper sheet 18 and a pressing plate 19. The clasp 11 is a circular ring member, the outer wall surface of the clasp 11 is a smooth wall surface, and the inner wall surface slightly extends inward to form a buckle shape. Referring to Figure 7 The launching head 12 comprises a flange base with a certain thickness and a cylinder protruding from the flange base, and the cylinder is located at the center of the flange base and integrally cast with the flange base. The left side of the flange base slightly extends outward to form a protrusion, which cooperates with the buckle formed by the inner side of the clasp 11, so that the clasp 11 can be clamped on the left side of the flange base of the launching head 12. The outer wall surface of the right half of the flange base is threaded, and the center of the right wall surface of the flange base is a cylindrical protrusion. A plurality of first through holes 12a are formed in the right side of the protruding cylinder, and a plurality of second through holes 12b are uniformly arranged on the right wall surface of the flange base along the circumferential direction. Referring to Figure 8 The inside of the flange base and the protruding cylinder of the launching head 12 are hollow, and the hollow inside of the flange base and the protruding cylinder forms a first gas chamber 12c, and the first through holes 12a are communicated with the first gas chamber 12c. The hollow inside of the flange base of the launching head 12 and the outer wall surface of the flange base form a plurality of second gas chambers 12d, which correspond to the second through holes 12b. The second gas chamber 12d is a gradually changing long and narrow circular tube structure with wide inner diameter at both ends and narrow inner diameter in the middle, which satisfies the Laval nozzle structure. When the gas quickly enters the second gas chamber 12d from the second through hole 12b, the gas flow rate will increase when it encounters the narrow inner diameter, and the gas flow rate will abnormally accelerate again when it passes through the narrow part according to the Laval nozzle effect, resulting in a sharp increase in gas flow rate. The Laval nozzle structure of the second gas chamber 12d can provide stronger launching power for the firing device of the present application.

[0033] Referring to Figure 9 and Figure 10 The mounting seat 13 is a variable diameter connector with different diameters at both ends, comprising a third through hole 13a, a third gas chamber 13b and a fourth gas chamber 13c. Referring to Figure 9 The left side of the mounting seat 13 is a larger diameter annular member, and the right side is a smaller diameter annular member, and the two are connected by a diameter gradually changing annular member, and the smaller end annular member is provided with a baffle inside the connection between the gradually changing annular member. The whole mounting seat 13 is integrally cast. The inner thread of the left side annular member matches the outer thread of the flange base of the launching head 12, so that the launching head 12 is screwed with the mounting seat 13. The inner thread of the smaller annular member on the right side of the mounting seat 13 is screwed with the firing assembly 2. The third through hole 13a is formed in the middle of the baffle inside the mounting seat 13, referring to Figure 9The third through hole 13a is located at the center of the baffle, and is used for connecting the third air chamber 13b and the fourth air chamber 13c. The third through hole 13a is located at the inner diameter of one side of the fourth air chamber 13c, and is expanded to form a circular clamping groove. After the mounting seat 13 is screwed with the launching head 12, the tapered annular segment of the mounting seat 13 forms the third air chamber 13b. After the smaller annular part on the right side of the mounting seat 13 is screwed with the firing assembly 2, the fourth air chamber 13c is formed in the smaller annular part.

[0034] Referring to Figure 6 The baffle 14 is circular, and is clamped between the clasp 11 and the launching head 12. The weight 15 and the net hammer 16 include a plurality of through holes, which are matched with the traction lines on the net support 17, and are connected with the net hammer 16. After installation, the weight 15 and the net hammer 16 are clamped at the narrow part of the second air chamber 12d. The net support 17 is placed in the first air chamber 12c. The copper sheet 18 is a thin copper disc, which is placed at the side of the third through hole 13a close to the fourth air chamber 13c. The pressing plate 19 is an annular member, and its outer diameter matches the expanded circular clamping groove at the side of the third through hole 13a close to the fourth air chamber 13c.

The annular groove 21b is located at the center of the outer ring of the right side ring of the firing device 21, and surrounds the outer side of the ring. The striker 21c is located at the center of the inside of the gas permeable hole 21a, and is a conical spike member.

[0036] Referring to Figure 16 and Figure 17 The gas cylinder mounting seat 22 includes a circular hole 22a, a gas cylinder fixing valve 22b, a first clamping groove 22c, and a second clamping groove 22d. The gas cylinder mounting seat 22 is a "convex" member integrally cast by a circular ring base, an outer ring, and an inner column. An annular groove is reserved between the outer ring and the inner column, and the width of the annular groove matches the right side ring of the firing device 21, so that the firing device 21 can be inserted into the gas cylinder mounting seat 22 through the annular groove. Referring to Figure 16, the outer wall surface of one end of the outer ring of the gas cylinder mounting seat 22 is threaded, and is screwed with the mounting seat 13. The other end of the outer ring is provided with a plurality of circular holes 22a, which are evenly arranged around the outer ring of the gas cylinder mounting seat 22, and the circular hole 22a and the annular groove 21b are movably clamped by the ball 210. Referring to Figure 13 When the annular groove 21b and the circular hole 22a are in the same position, the first limiting block 24 will extrude the ball 210, so that the circular hole 22a and the annular groove 21b are in the clamping state; when the first limiting block 24 leaves the position, the ball 210 will be extruded out of the circular hole 22a due to the action of the spring force, at this time the annular groove 21b is separated from the clamping of the ball 210, and the striker 21 will move to the direction of the gas cylinder mounting seat 22 due to the elastic force. The inner column of the gas cylinder mounting seat 22 is further provided with a gas cylinder fixing valve 22b. The gas cylinder fixing valve 22b is used to fix the bottle mouth of the gas cylinder 29, and the structure of the gas cylinder fixing valve 22b is matched with the air hole 21a, and the middle part is provided with a recess, so that the firing pin 21c can pass through the recess and contact the bottle mouth of the gas cylinder 29, so as to pierce the gas cylinder 29. The first clamping groove 22c is located on the inner side wall of the other end of the inner column of the gas cylinder mounting seat 22, which can be matched with the bottom cover 28, so that the bottom cover 28 can be clamped in the gas cylinder mounting seat 22. The second clamping groove 22d is located on the inner wall of the threaded end of the outer ring of the gas cylinder mounting seat 22, and a groove is formed along the inner wall. The second clamping groove 22d can cooperate with the second limiting block 212 to realize the clamping of the second limiting block 212.

[0037] Referring to Figure 13 The first spring 23 is a spring member with an inner diameter consistent with the outer diameter of the outer ring of the gas cylinder mounting seat 22, which is sleeved on the outer cylinder mounting seat 22, and one end is in contact with the first limiting block 24, and the other end is in contact with the mounting seat 13. The first limiting block 24 is a ring flange shaped member, including a wider bottom disc and a smaller convex disc; the inner diameter of the bottom disc and the convex disc of the first limiting block 24 is consistent with the outer diameter of the outer ring of the gas cylinder mounting seat 22, which is sleeved on the junction of the outer ring of the gas cylinder mounting seat 22 and the circular ring base, and is used for clamping the ball 210, the annular groove 21b and the circular hole 22a. Referring to Figure 11 and Figure 13, the rudder 25, the rudder arm 26 and the rudder mounting seat 27 together constitute an external module, wherein one end of the rudder mounting seat 27 is fixed to the outer side wall of the circular bottom of the gas cylinder mounting seat 22, and the other end is bolted with the rudder 25; the rudder 25 includes a rotating shaft, one end of which is bolted with the rudder mounting seat 27, and the other end can be bolted with an external machine such as a drone or a robot, for fixing the firing device of the present application to the external machine, thereby realizing unmanned and automated riot control operation. One end of the rudder arm 26 is rotationally connected with the rudder 25, and the other end abuts against the edge of the first limiting block 24. In use, the rudder arm 26 is controlled to rotate, and the end of the rudder arm 26 can push the first limiting block 24 to move axially. At this time, the ball 210 originally in the clamping state will move away from the clamping point due to the pushing force of the firing device 21, the firing device 21 moves axially, and the striker 21c rushes to the gas cylinder mounting seat 22, thereby realizing firing.

[0038] Referring to Figure 11 and Figure 13 , the bottom cover 28 is located at the bottom of the gas cylinder mounting seat 22, and the bottom cover 28 is composed of a cylindrical plug and a bottom cover holder, wherein the diameter of the cylindrical plug is consistent with the inner diameter of the circular bottom of the gas cylinder mounting seat 22, so that the cylindrical plug can be clamped at the bottom of the gas cylinder mounting seat 22, and a protrusion is further provided on the periphery of the middle circle of the cylindrical plug, which matches the first clamping groove 22c, so that the bottom cover 28 can be firmly clamped at the bottom of the gas cylinder mounting seat 22. The diameter of the bottom cover holder is greater than that of the cylindrical plug, which facilitates the installation and removal of the bottom cover 28. The gas cylinder 29 can be clamped in the gas cylinder compartment reserved in the gas cylinder mounting seat 22, and the mouth of the gas cylinder 29 can match the gas cylinder fixing valve 22b, so that the gas cylinder 29 can be fixed in the gas cylinder compartment. The length of the gas cylinder compartment reserved in the gas cylinder mounting seat 22 is slightly longer than the length of the gas cylinder 29, and the purpose is that when the gas cylinder 29 is pierced by the striker 21c, the gas cylinder 29 moves axially due to the pushing force of the gas, and moves away from the striker 21c, so as to avoid the striker 21c blocking the gas port and causing power waste.

[0039] Referring to Figure 13, the ball 210 includes a plurality of, the number is consistent with the number of round holes 22a, its size is consistent with the round hole 22a and ring groove 21b. The ball 210 can be flexible along the round hole 22a. The second spring 211 is located in the annular groove between the outer ring of the gas cylinder mounting seat 22 and the inner column, and one end is in contact with the circular ring-shaped bottom of the trigger 21, and the other end is in contact with the second limiting block 212. When the ball 210 is clamped in the ring groove 21b and the round hole 22a, the second spring 211 is in a compressed state. The second limiting block 212 is an annular member located at the junction of the gas cylinder mounting seat 22 and the trigger 21, and one side of the second limiting block 212 extends outward to form a clamping foot that matches the second clamping groove 22d, allowing the second limiting block 212 to be clamped in the gas cylinder mounting seat 22 to resist the second spring 211.

[0040] The portable trigger device of the present application is a trigger device that integrates fast stringing, fast loading, and simplified structure. In use, the device can be operated manually or combined with external machinery such as drones and robots for unmanned operation. The specific use process of the trigger device is as follows: after the trigger device is assembled, the trigger command is received, the rudder arm 26 is pushed or the first limiting block 24 is manually pushed. At this time, the ball 210 is released from the ring groove 21b due to the pushing force of the second spring 211 on the trigger 21 and the release of the first limiting block 24, the trigger 21 is impacted in the direction of the gas cylinder mounting seat 22 by the pushing force of the second spring 211, and the firing pin 21c pierces the gas cylinder 29. At this time, the gas cylinder 29 moves away from the firing pin 21c due to the reaction force, and starts to release gas; a large amount of gas quickly gathers in the fourth gas chamber 13c, and when the gas pressure reaches a certain value, the copper sheet 18 is broken, and high-pressure gas quickly enters the third gas chamber 13b through the third through hole 13a. At this time, part of the gas enters the first gas chamber 12c through the first through hole 12a, pushing the net holder 17 to start moving; the other part of the gas enters the second gas chamber 12d through the second through hole 12b, and due to the Laval effect, the gas is further accelerated to push the weight 15 and the net hammer 16, and the clasp ring 11 is knocked out, driving the net holder 17 to capture. After completing a shot, the mounting seat 13 is only needed to be unscrewed from the trigger assembly 2, the pressing plate 19 is buckled, and the new copper sheet 18 is replaced; the trigger 21 is manually pulled out, the ring groove 21b, the round hole 22a, and the ball 210 are returned to the clamping state again, and the mounting seat 13 and the trigger assembly 2 are screwed again. The bottom cover 28 is buckled, the new gas cylinder 29 is replaced, and the bottom cover 28 is buckled again. Thus, a new round of stringing and loading is completed, waiting for the next trigger command.

[0041] The striker 21c, the firing device and the gas cylinder 29 of the application are annularly mounted, the size of the firing device 21 coincides with the size of the gas cylinder 29, no redundant size is generated, the overall size of the device is reduced, the convenience and compatibility with other equipment are improved; and the firing device 21 of the application is provided with the gas permeable hole 21a, which makes the gas overflow from the gas cylinder 29 into the gas passage of the gas chamber conveniently and efficiently, and no more gas power is needed to push open the striker 21c and the firing device 21, a lot of gas power is saved, so that the application has greater range and power than the traditional firing device under the condition of the same gas cylinder specification; in addition, the application also fully utilizes the principle of the Laval nozzle, so that the range and power of the application are greatly increased. The structure of the second gas chamber 12d changes the surface contact between the weight 15 and the pipe wall into point contact, and there is no sliding friction force between the weight 15 and the pipe wall at the moment when the gas pushes the weight 15, the friction loss is reduced, and the power and range of the application are further improved. Moreover, the application has simple structure and convenient operation, when loading and replacing ammunition, the device does not need to be completely disassembled, only two parts, the mounting seat 13 and the bottom cover 28, need to be unscrewed, and the string loading and ammunition replacement can be completed, which can be deployed faster in emergency situations.
