The firing pin assembly is fixedly mounted at the rear end of the outer tube and is used to fire the projectile in the rope bullet assembly; the firing pin stop cover is threadedly mounted at the front end of the outer tube and is used to limit the depth of the firing pin of the firing pin assembly hitting the projectile of the rope bullet assembly; the trigger assembly is fixed inside the outer tube and is located at the front end of the firing pin assembly and is used to clamp or release the firing pin of the firing pin assembly; the safety cap is hinged to the outer tube through a pin and covers the trigger button of the trigger assembly to prevent the trigger button of the rope bullet gun from being accidentally triggered during carrying; the quick-change mechanism is located at the front end of the firing device and is used to quickly connect the rope bullet assembly and the firing device; the sight is fixed to the front end of the outer tube through the sight bracket to assist relevant personnel in quickly aiming at the target.

[0007] The firing pin assembly comprises a firing pin, a firing pin spring, a firing pin tube, a firing pin reset slider, a firing pin reset guide rod, a firing pin reset pull rod, a firing pin return spring, a firing pin reset pull ring, and a firing pin reset stop column. The firing pin tube is fixed inside the outer tube, the firing pin and the firing pin spring are installed in the first light hole of the firing pin tube, the firing pin spring is compressed and abuts against the shaft shoulder at the rear end of the firing pin, and the shaft shoulder at the front end of the firing pin is pressed against the right side surface of the trigger of the trigger assembly; the firing pin reset slider is fixed to the front end of the firing pin reset guide rod, the rear end of the firing pin reset guide rod is fixedly connected to the front end of the firing pin pull rod, and is coaxially installed with the firing pin reset spring in the second light hole of the firing pin tube, the firing pin reset pull ring passes through the small round hole at the tail end of the firing pin reset pull rod, and is hidden in the groove at the tail end of the firing pin tube; the firing pin reset stop column fixed on the firing pin passes through the notch on the side wall of the first light hole of the firing pin tube, and can move along the firing pin axis under the drive of the firing pin reset slider.

[0008] The trigger assembly comprises a trigger, a trigger spring, a trigger insert and a trigger button. The short shaft at the lower end of the trigger and the trigger spring are installed in the trigger insert fixed to the outer tube, and the short shaft at the upper end of the trigger passes through the through hole on the upper part of the outer tube and is connected to the trigger button.

[0009] The outer tube, locking outer ring, sleeve, top column, steel ball, locking spring and screw constitute the quick-change mechanism of the trigger. The steel balls are evenly distributed in the three ball holes of the outer tube, the sleeve is embedded in the semicircular blind hole on the front end surface of the outer tube and protrudes from the inner surface of the outer tube, the top column and the locking spring are installed in the sleeve, the locking outer ring is sleeved on the front end of the outer tube, the ball head at the front end of the top column is pushed on the inner end surface of the locking outer ring by the locking spring, the screw fixed on the locking outer ring is stuck in the L-shaped groove at the front end of the outer tube, and can slide in the L-shaped groove, so the locking outer ring can rotate at a small angle along the circumference of the outer tube and slide at a small distance along the axial direction, and there is an annular groove on the inner surface of the locking outer ring that can accommodate some steel balls, and when it is aligned with the ball hole, the steel ball can enter the annular groove. The quick-change mechanism can ensure that the used rope bullet assembly can be quickly removed from the trigger, and a new rope bullet assembly can be quickly installed, meeting the requirements of fast and repeated firing of the rope bullet gun.

[0010] The rope elastic assembly includes a rope elastic shell, a traction head, a rope, a shear pin, a restraining hook, a piston, a screw plug, an end cover, a body, a body fixing seat, and a nut. A pin hole is provided on the side wall at the exit of the acceleration channel of the rope elastic shell and on the front end of the traction head. The front end of the traction head is connected to one end of the rope and is placed in the acceleration channel. The shear pin passes through the pin holes on the side wall of the acceleration channel and on the traction head to fix the two relatively. The tail end of the traction head is located in the groove at the front end of the piston, and the rear end of the piston is placed in the through hole of the screw plug fixed in the acceleration channel. The exit of the acceleration channel of the rope elastic shell is a stepped hole to prevent the piston from rushing out of the rope elastic shell during movement; two restraining hooks are tied to both ends of the rope, which are respectively received in the cavity at the front end of the rope elastic shell after being coiled, and are sealed by the end cover to prevent it from rushing out during carrying. The rope and the binding hook are separated from the rope bomb shell; after the projectile is installed in the projectile fixing seat, it is fixed in the nut by thread, and the nut is fixed to the tail end of the rope bomb shell by thread; the column at the tail end of the rope bomb shell has a semicircular ring groove that can accommodate part of the steel ball and an axial semicircular straight groove for connecting the sleeve. When the rope bomb assembly is connected to the trigger, the steel ball on the trigger is stuck in the semicircular ring groove to limit the axial movement of the rope bomb assembly, and the sleeve on the inner surface of the protruding outer cylinder on the trigger is stuck in the axial semicircular straight groove to limit the circumferential rotation of the rope bomb assembly to ensure the horizontal shooting of the traction head; the angle formed by the axes of the two groups of acceleration channels of the rope bomb shell on the horizontal plane is not greater than 20°. Using shear pins of different diameters or different strength materials can change the initial pressure of the gas generated inside the rope bomb shell when the piston of the rope bomb assembly starts to move. By loading projectiles of different power levels into the rope bomb assembly or changing the mass of the traction head, the rope bullet gun can shoot the rope at different distances. The end cover and the shell of the rope bullet assembly are removable and reassembled. After the rope bullet assembly is fired, the traction head, rope and binding hook can be resealed through the end cover, and the bullet body can be replaced and reused.

[0011] As a further improvement of the above technical solution, no pin holes are provided on the side wall at the outlet of the acceleration channel of the rope spring housing of the rope spring assembly and on the front end of the traction head, and no shear pins are installed.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The rope bullet gun of the present invention enables relevant personnel to complete the arrest process at a long distance, thereby ensuring the safety of relevant personnel during the arrest process.

[0014] 2. The rope bullet gun of the present invention will not cause serious harm to the target during the capture process.

[0041] like Figure 3 , Figure 4 and Figure 5As shown, the firing pin assembly 11 includes a firing pin 111, a firing pin spring 112, a firing pin tube 113, a firing pin reset guide rod 114, a firing pin reset slide block 115, a firing pin reset pull rod 116, a firing pin reset spring 117, a firing pin reset pull ring 118, and a firing pin reset stop column 119. The firing pin tube 113 is fixed inside the outer tube 12, and the firing pin 111 and the firing pin spring 112 are installed in the first light hole 1131 of the firing pin tube 113. After being compressed, the firing pin spring 112 rests on the shoulder at the rear end of the firing pin 1111, and the shoulder at the front end of the firing pin 111 is pressed against the right side surface of the trigger 141 of the trigger assembly 14; the front end of the firing pin reset guide rod 114 is fixedly connected to the firing pin reset slide block 115, and its rear end is fixedly connected to the front end of the firing pin pull rod 116, and then coaxially installed with the firing pin reset spring 117 in the second light hole 1132 of the firing pin tube; the firing pin reset pull ring 118 passes through the small circular hole at the rear end of the firing pin reset pull rod 116, and is hidden in the groove at the rear end of the firing pin tube 113; the firing pin reset stop column 119 fixed on the firing pin 111 passes through the notch on the side wall of the first light hole 1131 of the firing pin tube 113, and can move along the axial direction of the firing pin 111 under the drive of the firing pin reset slide block 114.

[0042] like Figure 2 As shown, the trigger assembly 14 includes a trigger 141, a trigger spring 142, a trigger insert 143, and a trigger button 144. The short shaft at the lower end of the trigger 141 and the trigger spring 142 are installed in the trigger insert 143 fixed to the outer tube 12, and the short shaft at the upper end of the trigger 141 passes through the through hole at the upper part of the outer tube 12 and is connected to the trigger button 144.

[0043] like Figure 6 , Figure 7 and Figure 8As shown, the outer tube 12, sleeve 161, top column 162, locking spring 163, locking outer ring 164, screw 165, and steel ball 166 constitute the quick-change mechanism 16 of the firing device 1. The sleeve 161 is embedded in the semicircular blind hole 1201 on the front end surface of the outer tube 12 and protrudes from the inner surface of the outer tube 12. The top column 162 and the locking spring 163 are installed in the sleeve 161 in a front-to-back order. The locking outer ring 164 is sleeved on the front end of the outer tube 12. The ball head at the front end of the top column 162 is pushed by the locking spring 163 to press against the inner end surface of the locking outer ring 164. The screw 165 fixed on the locking outer ring 164 is clamped into the L at the front end of the outer tube 12. The locking outer ring 164 can be inserted into the L-shaped groove 1202 and can slide in the L-shaped groove 1202, so the locking outer ring 164 can rotate at a small angle along the circumference of the outer tube 12 and slide at a small distance along the axial direction. The steel ball 166 is placed in three ball holes 1203 evenly distributed circumferentially at the front end of the outer tube 12. The inner surface of the locking outer ring 164 has an annular groove 1641 that can accommodate half of the steel ball 166. When the annular groove 1641 of the locking outer ring 164 is aligned with the ball hole 1203, the steel ball 166 can enter the annular groove 1641. The quick-change mechanism 16 can ensure that the used rope bullet assembly 2 can be quickly removed from the firing device 1, and a new rope bullet assembly 2 can be quickly installed, meeting the requirements of fast and repeated firing of the rope bullet gun.

[0044] like Fig. 9 and 10As shown, the rope bullet assembly 2 includes a rope bullet housing 201, a traction head 202, a rope 203, a shear pin 204, a piston 205, a screw plug 206, a tie hook 207, an end cover 208, a nail bullet 209, a bullet body fixing seat 210, and a nut 211. The two acceleration channels of the rope bullet housing 201 have an angle of 15° in the horizontal plane, which can ensure that when the two traction heads 202 drive the rope 203 to fly to the target 10 meters away from the launch point and contact it, the rope 203 can be fully deployed; a pin hole is provided on the side wall at the exit of the acceleration channel 2011 and on the front end of the traction head 202, and the front end of the traction head 202 and the rope 203 are connected. After one end is connected, it is placed in the acceleration channel 2011, and the shear pin 204 passes through the pin holes on the side wall of the acceleration channel 2011 and the traction head 202, so that the two are relatively fixed, and the tail end of the traction head 202 is placed in the groove at the front end of the piston 205, and the rear end of the piston 205 is placed in the through hole of the screw plug 206 fixed in the acceleration channel 2011. The outlet of the acceleration channel 2011 of the rope shell 201 is a stepped hole, which can prevent the piston 205 from rushing out of the rope shell 201 during the movement; the two ends of the rope 203 are respectively tied with binding hooks 207, and after being coiled, they are collected in the rope shell 201 together with the binding hooks 207. 01 is in the cavity 2012 at the front end and is encapsulated by the end cover 208 to prevent the rope 203 and the binding hook 207 from being separated from the rope shell 201 during the carrying process of the rope gun; the column at the rear end of the rope shell 201 has a semicircular ring groove 2013 that can accommodate 1 / 3 of the steel ball 166 and an axial semicircular straight groove 2014 for connecting the sleeve 161. When the rope assembly 2 is connected to the trigger 1, the steel ball 166 on the trigger 1 is stuck in the semicircular ring groove 2013 to limit the axial movement of the rope assembly 2, and the sleeve 161 protruding from the inner surface of the outer cylinder 12 on the trigger 1 is stuck in the axial semicircular straight groove 2014 In order to limit the circumferential rotation of the rope bullet assembly 2, the traction head 202 is ensured to be ejected horizontally; after the nail bullet 209 is loaded into the body fixing seat 210, the body fixing seat 210 is fixed in the nut 211 by thread, and the nut 211 is fixed in the inside of the tail end of the rope bullet shell 201 by thread. The nail bullet 209 used in the rope bullet assembly 2 in this embodiment is an S1 nail bullet with a power level of 5 produced by Sichuan Nanshan Nail Fastening Equipment Co., Ltd. According to actual conditions, nail bullets of other power levels can be loaded into the rope bullet assembly 2, such as S3 nail bullets with a power level of 5, so that the rope bullet gun can adapt to different restraint distances. The end cover 208 of the rope bullet assembly 2 and the rope bullet shell 201 are a removable snap-on connection mode. After the rope bullet assembly 2 is fired, the traction head 202, the rope 203 and the restraining hook 207 can be re-encapsulated through the end cover 208, and after the nail bullet 209 is replaced, it can be reused.

[0045] Reference Fig.12When using the rope gun, the relevant personnel turn on the laser sight 17, aim at the target through the emitted laser, then open the safety cap 15, press the trigger button 144, the trigger button 144 drives the trigger 141 to move vertically downward, the right side of the trigger 141 is separated from the shaft shoulder at the front end of the firing pin 111, and the firing pin 111 is in the firing pin spring 112. Under the push of the piston 205, the needle head at its front end hits the rear end of the nail bullet 209 of the rope bullet assembly 2, and then the nail bullet 209 explodes in the rope bullet assembly 2. After the nail bullet 209 explodes, the gas pressure generated gradually increases. When the pressure in the double rope bullet assembly 2 reaches 4MPa, the piston 205 begins to push the traction head 202 to move relative to the rope bullet shell 201. Finally, the 1mm diameter hard aluminum shear pin 204 is cut off. The traction head 202 begins to accelerate under the push of the piston 205 and pushes open the end cover 208 at the front end of the rope bullet shell 201. The traction head 202 and the rope 203 connected thereto rush out of the rope bullet shell 201 at high speed. The rope 203 gradually unfolds during the high-speed movement and straightens before contacting the target. After the rope 203 contacts the target, it quickly wraps around the target. The two binding hooks 207 on the rope 203 tightly hook the target's clothes, so that the rope 203 can be securely wrapped around the target.

[0046] Reference Figure 6 , Figure 7 , Figure 8 and Fig.12 The figure shows the process of disassembling the rope bullet assembly 2 from the firing device 1. When disassembling the fired rope bullet assembly 2, the locking outer ring 164 at the front end of the firing device 1 is rotated counterclockwise by a certain angle, and after the screw 165 fixed on the locking outer ring 164 enters the axial segment groove of the L-shaped groove 1202 of the outer tube 12, the top column 162 pushes the locking outer ring 164 to move forward along the axis by a certain distance under the elastic force of the locking spring 163, so that the semicircular annular groove 1641 of the locking outer ring 164 is aligned with the ball hole 1203 on the outer tube 12, and the rope bullet assembly 2 is pulled forward along its axis, and the steel ball 166 enters the annular groove 1641 of the locking outer ring 164 under the pressure of the rope bullet housing 201, that is, the axial constraint of the steel ball 166 on the rope bullet assembly 2 is released, and the rope bullet assembly 2 is separated from the firing device 1, that is, the rope bullet assembly 2 is completely disassembled from the firing device 1.

[0047] Before loading a new rope bomb assembly 2, the firing pin 111 must be reset first, refer to Figure 2 , Figure 5 and Fig.13The figure shows the process of resetting the firing pin 101. The firing pin reset pull ring 118 is buckled out from the groove at the rear end of the firing pin tube 113, and then the firing pin reset pull ring 118 is pulled backwards, and the firing pin reset pull ring 118 drives the firing pin reset pull rod 116 and the firing pin reset guide rod 114 connected thereto and the firing pin reset slide block 115 fixed on the firing pin reset guide rod 114 to move backwards, at this time, the firing pin reset stop column 119 fixedly connected to the firing pin 111 is pushed backwards by the firing pin reset slide block 115, and the firing pin 111 slides backwards in the first light hole 1131 of the firing pin tube 113 driven by the firing pin reset stop column 119, and when the shaft shoulder at the front end of the firing pin 111 passes over the right side of the trigger 141, due to the elastic force of the trigger spring 142, the trigger 141 moves upwards, and the right side of its circular ring is stuck at the shaft shoulder at the front end of the firing pin 111, and the firing pin 111 returns to the firing state. At this time, release the firing pin reset pull ring 118, and the firing pin reset guide rod 114 and the firing pin reset pull rod 116 move forward under the push of the firing pin reset spring 117 until the firing pin reset pull rod 116 completely returns to the second light hole 1132 of the firing pin tube 113, and then retract the firing pin reset pull ring 118 into the groove at the tail of the firing pin tube 113.

[0048] Reference Figure 6 , Figure 7 , Figure 8 and Fig.14 The figure shows the loading process of the rope elastic assembly 2. After the firing pin 111 is reset, the marking line on the new rope elastic assembly 2 is aligned with the marking line on the firing device 1, and the assembly is inserted into the front end of the firing device 1 along the axis, and then the locking outer ring 164 is pushed backward along the axis of the firing device 1 for a certain distance, so that the ring groove 1641 on the locking outer ring 164 is staggered with the ball hole 1203 of the outer tube 12, and the steel ball 166 is squeezed into the semicircular ring groove 2013 of the rope elastic housing 201, and the new rope elastic assembly 2 is clamped at the front end of the firing device 1, and finally the locking outer ring 164 is rotated clockwise by a certain angle, so that the screw 165 fixed on the locking outer ring 164 is clamped into the circumferential groove section of the L-shaped groove 1202 of the outer tube 12, and the loading of the rope elastic assembly 2 is completed.

[0049] Embodiment 2

[0050] As a further preferred embodiment, Fig.15 As shown, combined with Fig. 9In contrast, the side wall at the exit of the acceleration channel 3011 of the rope bullet housing 301 of the rope bullet assembly 3 and the front end of the traction head 302 are not provided with pin holes, and no shear pin 204 is installed. After the nail bullet 209 of the rope bullet assembly 3 is fired, it starts to generate gas inside the rope bullet housing 301 and pushes the piston 205 to move. The piston 205 drives the traction head 302 to accelerate and pushes open the end cover 208 at the front end of the rope bullet housing 201 until the traction head 302 is completely separated from the acceleration channel 3011 of the rope bullet housing 301. The traction head 302 is accelerated, and then drives the rope 203 to continue to fly toward the target and finally bind the target.
