[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] like Figures 1 to 9 As shown, an offensive security device includes a main base 1, a defense system, and a rotating chassis 5. The main base 1 has a U-shaped structure, and the defense system is installed within the U-shaped structure of the main base 1. The defense system includes a powerful attack box 2, a special ammunition launch box 3, and a non-powerful attack box 4. The powerful attack box 2 and the special ammunition launch box 3, and the special ammunition launch box 3 and the non-powerful attack box 4 are fixedly connected through the same connecting holes. Bearings and bearing seats are distributed on both sides inside the main base 1. The powerful attack box 2 is fixedly connected to a driven shaft 17, which passes through the bearings to hinge the powerful attack box 2 to the main base 1. The non-powerful attack box 4 is fixedly connected to a drive shaft 16, which passes through the bearing seats to hinge the non-powerful attack box to the main base 1. Since the connecting holes between each box are the same, the user can determine the number of boxes in the security device according to specific circumstances, and the functionality is expandable.

[0035] The main base 1 includes a base 10, an alarm device 11, a monitoring device 12, an antenna 13, an elevation / lowering mechanism 14, an elevation / lowering mechanism shaft 15, a drive shaft 16, a driven shaft 17, and a driven shaft bearing seat 18. The alarm device 11 and antenna 13 are fixedly mounted on the top of the base 10, and the monitoring device 12 is fixedly mounted on the bottom of the base 10. One side of the base 10 includes a first communication port 101, a second communication port 102, and a first control module storage box 103. The elevation / lowering mechanism 14 is also fixedly mounted on this side. 15 is fixed on the high-low mechanism 14. The drive shaft 16 is keyed to the high-low mechanism shaft plate 15 to realize transmission. The drive shaft 16 is screwed on to prevent the high-low mechanism shaft plate 15 from sliding relative to each other. The other side of the base 10 includes a base window, a third communication port 105, and a backup power storage box 106. The driven shaft 17 passes through the driven shaft bearing seat 18 and is screwed on with a nut to prevent the driven shaft 17 from sliding relative to the driven shaft bearing seat 18. The back of the base 10 also includes a second control module storage box 107.

[0036] Under normal circumstances, this security device is powered by a wire socket. In the event of a power outage or other emergency, the power supply in the backup power storage box 106 will temporarily supply power to ensure the continuous use of the security device.

[0037] The powerful attack box 2 includes an attack box body 21, an attack box bottom panel 22, a cocking device 23, a trigger pull device 24, a shell ejection device 25, and an attack pistol. The attack box body includes an attack pistol mounting slot 210, a second servo mounting slot 211, a second servo mounting slot 212, and a grip mounting slot 213. The attack pistol mounting slot 210 includes a concave mounting slot 2100 and a spring-damped shock absorber 2101. The bottom of the spring-damped shock absorber 2101 is fixedly installed on the bottom of the attack box body 21 by bolts, and the top is connected to the concave mounting slot 2100 by bolts. The attack pistol in the powerful attack box is placed upside down in the grip mounting slot 213 and the attack pistol mounting slot 210. The upside-down attack pistol method lowers the overall center of gravity, and the spring-damped shock absorber 2101 at the bottom of the mounting slots helps maintain stability and accuracy during firing.

[0038] The cocking mechanism 23 is symmetrically distributed on both sides of the attack pistol, including a push rod motor 230, a push rod motor connector cap 231, a flange coupling ring 232, a sliding connecting block 233, a through-type stepper motor 234, a lead screw nut 235, and a vise jaw 236. The push rod motor 230 is fixedly mounted on the base plate of the attack housing 21 by bolts. One side of the push rod motor connector cap 231 is connected to the push rod motor 230 connector, and the other side is connected to the flange coupling ring 232. The flange coupling ring 232 is connected to the sliding connecting block 233 by bolts. The through-type stepper motor 234 is fixedly mounted on the top of the sliding connecting block 233 by a motor mounting base and is threadedly connected to the lead screw nut 235. The lead screw nut 235 is fixedly mounted on the top of the sliding connecting block 233. The vise jaw 236 is connected to and tightened with the lead screw of the through-type stepper motor 234.

[0039] Before the pistol is chambered, the two through-type stepper motors 234 simultaneously rotate their lead screws, pushing the vise jaws 236 connected to the lead screws to clamp the pistol slide. During chambering, when the control push rod motor pulls backward, the connector cap connected to the push rod motor, the flange coupling ring 232 connected to the connector cap, and the sliding connecting block 233 connected to the flange coupling ring 232 will all move backward together. The sliding connecting block 233 will also drive the through-type stepper motor mounted on the top to move backward, thereby pulling the pistol slide and chambering the bullet. At the end of chambering, the two through-type stepper motors... The motor will rotate the lead screw to pull back the vise jaws 236, releasing the slide of the attack pistol. Due to the internal structure of the attack pistol, the released slide will automatically return to its original position. At the same time, the push rod motor will return to its original length, and the bullet loading process will end. Since there are pull-loading devices 23 on both sides of the attack pistol, the pulling force is increased while ensuring the force is balanced on both sides of the pistol. In addition, if a jam occurs during firing, this device can pull the slide on the pistol again to resolve the jamming problem. The entire firing process is automatically completed by the internal device, and the pull-loading method has stability and autonomy.

[0040] The trigger mechanism includes a first servo, a first link 241, a second link 242, and a third link 243. The first servo is fixedly installed in a second servo mounting slot 211. The first link 241 is hinged to the servo via a shoulder screw. One end of the second link 242 has a U-shaped groove and a mating hole. The U-shaped groove is bolted to the first link 241. The third link 243 has a Y-shaped structure, with one end bolted to the mating hole of the second link 242 and the other end bolted to the first link 241. The first link 241 and the second link 242... The first link 241, the second link 242, and the third link 243 are connected in a triangular structure. Because the first link 241, the second link 242, and the third link 243 are connected in a triangular structure, they cannot move relative to each other. When the trigger is pulled, the first servo will drive the hinged first link 241 to move backward, which in turn drives the second and third links 243 to move backward, and then drives the third link 243 to pull the trigger, completing the trigger pulling process. The whole device has a simple structure, and the triangular connection structure makes the connection of each link relatively stable. The trigger pulling method is simple and stable.

[0041] The ejection device 25 includes a second servo motor 250, an ejection linkage 251, a connecting hinge 252, and an ejection gate 253. The second servo motor 250 is fixedly installed in the mounting slot of the second servo motor 250. One end of the linkage is hinged to the servo motor through a U-shaped groove using a shoulder screw, and the other end is fixedly connected to one side of the hinge by bolts. The other side of the hinge is fixedly connected to the ejection gate 253 by bolts. During ejection, the second servo motor 250 is controlled to drive the ejection linkage 251 to move. Since one side of the connecting hinge 252 is fixed to the ejection gate 253 and the other side is fixed to the ejection linkage 251, the connecting hinge 252 will also be driven, thereby opening the ejection gate 253. After the attack pistol is fired, the bullet casing will enter the main body base 1 through the opened ejection gate 253 and the base window, completing the ejection process. The ejection device has a simple structure, is easy to assemble, and has a simple ejection method.

[0042] The special ammunition launcher 3 comprises two layers, upper and lower. Each layer includes a launch box body, a bottom panel 31, a launch spring 32, a launch plate 33, an electromagnetic latch 34, and an electromagnetic latch mounting base 35. The bottom panel 31 includes a launch tube 300. One end of the launch spring 32 is bonded to the bottom panel, and the other end is bonded to the launch plate 33. The electromagnetic latch 34 is fixedly mounted on the electromagnetic latch mounting base 35 to control the release of the launch spring 32. One side of the base 35 is a rectangular plate, and the launch box is connected to the rectangular plate. The special projectile 301 is placed on the launch plate 33. When the electromagnetic latch 34 retracts, the compressed spring will push the connected launch plate 33, thereby pushing the special projectile 301 to achieve the launching function. When it is necessary to reload the special projectile 301, it is only necessary to compress the launch plate 33 to the electromagnetic latch 34 so that it is locked by the electromagnetic latch 34. The special projectile launch box 3 has a simple structure and can be reused. The launching method is practical and economical.

[0043] The non-powerful attack box 4 includes an attack box body 21, an attack box bottom panel 22, a pulling and loading device 23, and a trigger pulling device 24. The internal structure of the non-powerful attack box 4 is exactly the same as that of the powerful attack box, except that it does not have an ejection device 25. It will not be described in detail here.

[0044] The rotating chassis 5 includes a chassis body 51 and a steering mechanism 52. The main base 1 is bolted to the turntable of the steering mechanism 52. The steering mechanism 52 is fixedly installed inside the chassis body 51. The entire attack security device is installed through the chassis mounting holes 53 at the four corners of the chassis body 51. When installing, the user only needs to set the holes at the same positions. Therefore, the attack security device can be installed on indoor walls or on other platforms. The installation method is simple and universal.

[0045] The first control module storage box 103 is used to store the first control module. The first control module is electrically connected to the alarm module 11, monitoring device 12, antenna 13 and high / low frequency unit 14 on the top of the base 10. The first control module is electrically connected to the defense system through the second communication port 102. The second control module storage box 107 is used to store the second control module. The second control module is electrically connected to the first control module on one side of the base 10 through the first communication port 101. The second control module is electrically connected to the backup power supply on the other side of the base 10 through the third communication port 105.

[0046] Working Principle: Before use, the device is installed on an indoor wall or other platform through the mounting holes 53 on the chassis. When in use, if the monitor detects an intruder through the monitoring device 12 on the top of the base 10, the alarm device 11 will first warn the intruder to leave the security area immediately. When the intruder leaves the security area, the security device returns to its original state. If the intruder has not left, a second security mode can be adopted, which activates the alarm device 11 and fires non-powerful ammunition, such as rubber bullets or BBs, to warn and interfere with the intruder, and sends a signal to notify other security personnel to rush to the scene. If the intruder still has not left the security area, a third security mode will be adopted, which fires special ammunition, such as tear gas, to mark, interfere with, and drive away the intruder, and activates the alarm device 11. If the monitor finds that the intruder has not left the security area and there is a high possibility of causing greater damage, the security device can be remotely controlled.

[0047] The foregoing has described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
