Detailed implementation manners

[0026] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] Referring to Figures 1 - 10 , the embodiment of the present utility model provides a multi-functional arrest type police steel fork for safely subduing perpetrators by various means. The police steel fork includes a fork rod tube 18, a fork housing 9 and a fork body 3. A motor 13 is built in the fork rod tube 18, and the output end of the motor 13 is drivingly connected to a reduction gearbox 12.

[0028] The output end of the motor 13 cooperates with the reduction gearbox 12 to output appropriate power transmission. In the embodiment of the present utility model, the fork rod tube 18 is made of a high-strength bakelite tube with a length of 2 m, an outer diameter of 36 mm and an inner diameter of 34 mm, and the density of the tube material is about 1.5 g / cm 3 , and it can bear a weight of more than 50 kg and is inexpensive.

[0029] The fork housing 9 is connected to one end of the fork rod tube 18. A ball screw pair is arranged inside the fork housing 9. Bearings are rotatably connected to both ends of the screw rod 10 of the ball screw pair, and the bearings are connected to the inner wall of the fork housing 9 through bearing seats. One end of the screw rod 10 passes through a bearing and is connected to the output end of the reduction gearbox 12 through a coupling 11.

[0030] In the embodiment of the present utility model, the bearings connected to both ends of the screw rod 10 of the ball screw pair are respectively connected to the inner wall of the fork housing 9 through a front bearing seat 16 and a rear bearing seat 17. The screw rod 10 is coaxial with the fork rod tube 18. The screw rod 10 passes through the bearing on the rear bearing seat 17 and is drivingly connected to the reduction gearbox 12, so that the nut 8 of the ball screw pair reciprocates along the screw rod 10.

[0031] The fork body 3 has a C-shaped structure. Two fork bodies 3 are arranged opposite to each other and rotate towards each other. One end of the fork body 3 is rotatably connected to the nut 8 of the ball screw pair inside the fork housing 9 through an opening at the top of the fork housing 9. The other end of the fork body 2 is unidirectionally and inwardly rotatably connected to an anti-retreat fork 1. When the two fork bodies 3 rotate towards each other, the front ends of the two anti-retreat forks 1 abut against each other and then rotate inward.

[0032] The fork housing 9 has a triangular structure. Pin shafts 7 are respectively connected to both sides of the top of the fork housing 9. When the two fork bodies 3 rotate towards each other, the outer sides of the fork bodies 3 slide and contact the pin shafts 7, and the inner sides of the fork bodies 3 are in rolling contact with rollers 27. The rollers 27 are connected to the inner side of the fork housing 9 through first torsion springs 28.

[0033] The fork body 3 is cast from aluminum alloy, which can ensure strength and reduce weight. The top of the fork housing 9 has an opening, the size of the hole is larger than the cross-sectional size of the fork body 3, one end of the fork body 3 is rotatably connected to the ball screw pair, and the other end extends from the opening on the top of the fork housing 9 to the outside of the fork housing 9 and is connected to the anti-backlash fork 1 at the end.

[0034] When the motor 13 rotates forward, the motor 13 drives the screw rod 10 to rotate through the reduction box 12, so that the nut 8 rotates along the screw rod 10. Figure 2 The nut 8 drives the ends of the two fork bodies 3 to move downward, and the outer sides of the fork bodies 3 are closed toward the middle under the obstruction of the pin 7 to achieve clamping. When the motor 13 is reversed, the nut 8 moves upward along the screw rod 10, pushing the two fork bodies 3 to move forward to achieve loosening.

[0035] A pin shaft 7, a roller 27 and a first torsion spring 28 are provided on both sides of each fork body 3. When the fork body 3 moves with the nut 8 of the ball screw pair, under the action of the first torsion spring 28, the two sides of the fork body 3 maintain contact with the pin shaft 7 and the roller 27. The pin shaft 7 and the roller 27 laterally limit the fork body 3, thereby improving the stability of the fork body 3 and preventing the fork body 3 from shaking, which is conducive to more precise control of the degree of clamping and loosening of the fork body 3.

[0036] In the embodiment of the utility model, the front end of the anti-backward fork 1 has an inwardly curved arc structure, and a second torsion spring 29 for returning the anti-backward fork 1 to its original position is provided at the rotation connection between the anti-backward fork 1 and the fork body 3 .

[0037] When the fork body 3 is closed, the arc-shaped structure at the front end of the anti-backward fork 1 can make the anti-backward fork 1 naturally bend inward after contact, thereby restricting the perpetrator from retreating backward from the fork body 3. When the fork body 3 is released, the two anti-backward forks 1 at the front end of the two fork bodies 3 are separated, and under the action of the second torsion spring 29, the two anti-backward forks 1 can automatically reset.

[0038] In order to further clamp the abuser, in the embodiment of the utility model, the fork rod tube 18 is equipped with an air pump 15, the inner side of the fork body 3 is connected to the airbag 2 along the length direction, and the output end of the air pump 15 is connected to the airbag 2 through the tracheal tee 14 and the air guide tube.

[0039] After the fork bodies 3 clamp the attacker, the air pump 15 is started to inflate the two air bags 2, thereby assisting the fork bodies 3 in clamping the attacker. The air bags 2 can increase the speed and reliability of clamping and better prevent the attacker from being injured.

[0040] In order to deal with the perpetrators holding steel knives or other weapons, in the embodiment of the utility model, the fork rod tube 18 has a built-in 12V lithium battery 24, and the top of the fork shell 9 is rotatably connected to the electromagnet 4 through the universal joint 5, and the electromagnet 4 is electrically connected to the 12V lithium battery 24.

[0041] The electromagnet 4 is powered by a 12V lithium battery 24, and the electromagnet 4 can absorb the steel knife or other weapons used by the perpetrator, thereby achieving the purpose of disarming.

[0042] In addition, in one embodiment of the utility model, a fixing ring 22 is fixedly connected to one side of the middle part of the fork rod tube 18 close to the fork housing 9, and a flashing light 21 is rotatably connected to the outer side of the fixing ring 22 through a damping hinge, and the flashing light 21 is electrically connected to a 12V lithium battery 24.

[0043] The strong flashing light of the strobe light 21 can dazzle the attacker and blind him / her for a short time, thereby making him / her lose the ability to commit violence in a short period of time, making it easier to subdue him / her. The damping hinge can be used to adjust the illumination angle of the strobe light 21 to ensure that the strobe light 21 can still illuminate the attacker's eyes when the fork body 3 is used to clamp the attacker's waist or legs.

[0044] The overall length of the police steel fork provided in the embodiment of the utility model is about 2.5m. In order to facilitate carrying and storage, the fork rod tube 18 is a detachable two-section structure. The fork rod tube 18 consists of a first fork rod tube 181 and a second fork rod tube 182. The end of the first fork rod tube 181 is fixedly connected to the first connecting tube 19, and the end of the second fork rod tube 182 is fixedly connected to the second connecting tube 20. An open connecting tube 191 extends from one end of the first connecting tube 19, and a conical expansion plug 201 is recessed at one end of the second connecting tube 20. The open connecting tube 191 is plugged into the conical expansion plug 201. The outer wall of the first connecting tube 19 is connected to a buckle 192, and the outer wall of the second connecting tube 20 forms a protrusion 202, and the buckle 192 is locked with the protrusion 202.

[0045] The two sections of the fork rod tube 18 in the embodiment of the utility model are the first fork rod tube 181 and the second fork rod tube 182. The first fork rod tube 181 and the second fork rod tube 182 are connected by the first connecting tube 19 and the second connecting tube 20 at the end. The open connecting tube 191 on the first connecting tube 19 can be plugged into the conical expansion plug 201 on the second connecting tube 20. After plugging, the buckle 192 is used to cooperate with the protrusion 202 to lock it, so that the first fork rod tube 181 and the second fork rod tube 182 are connected as a whole.

[0046] To further describe the above, the fork rod tube 18 is configured as a foldable structure, which is convenient for overall carrying and storage. Specifically, the outer wall of the first connecting tube 19 is also connected to a movable hinge male head 193, and the movable hinge male head 193 is provided with a hinge slot 194. The outer wall of the second connecting tube 20 is also connected to a movable hinge female head 203, and the movable hinge female head 203 is connected to a hinge pin 204, and the hinge pin 204 is slidably connected in the hinge slot 194.

[0047] With this setting, the first fork rod tube 181 and the second fork rod tube 182 can rotate relative to each other and can also move relative to each other to achieve insertion and separation. When not in use, open the buckle 192, separate the open connection cylinder 191 on the first connecting pipe 19 and the tapered expansion plug 201 on the second connecting pipe 20, and then rotate the second fork rod tube 182 so that the hinge pin 204 on the second connecting pipe 20 rotates and slides in the hinge chute 194 to achieve the folding of the first fork rod tube 17 and the second fork rod tube 18.

[0048] In the embodiment of the present utility model, the motor 13, the air pump 15, and the strobe light 21 are all powered by a 12V lithium battery 24 and are respectively provided with separate push-button control switches. The switches are arranged on the outer wall of the fork rod tube 18 and are respectively provided with markings. The 12V lithium battery 24 is a 12V rechargeable lithium battery, and the 12V lithium battery 24 is provided with a main power switch 25 to facilitate disconnecting the power supply of all electrical components.

[0049] To achieve intelligent control, the embodiment of the present utility model further includes a processor 23 and a voice module 26. The voice module 26 is electrically connected to the processor 23, and the processor 23 is electrically connected to the power switches of the motor 13, the air pump 15, the electromagnet 4, and the strobe light 21.

[0050] The motor 13, the air pump 15, the speed reducer 12, the processor 23, and the voice module 26 are all fixed inside the fork rod tube 18 by screws. The voice module 26 can recognize specific voice commands set by the user and then transmit the corresponding commands to the processor 23. The processor 23 controls the power switches of the motor 13, the air pump 15, the electromagnet 4, and the strobe light 21 to be turned on or off to perform corresponding actions. The voice module 26 can also customize control passwords and modes. For example, when the fork body 3 clamps the perpetrator, if the law enforcement officer does not issue a release command, the fork body 3 will not release. However, if the perpetrator is strong enough, he may break free from the law enforcement officer with the steel fork clamped on his body and then escape or counterattack. At this time, the law enforcement officer can remotely continue to tighten the fork body 3 through a voice command, so that the perpetrator loses the ability to resist due to the pain caused by being clamped by the fork body 3.

[0051] When the multifunctional arrest-type police steel fork provided by the embodiment of the present utility model is in use, turn on the main power switch 25. Hold the fork rod tube 18 by hand and use the fork body 3 to surround the perpetrator. Start the motor 13, and transmit the power through the speed reducer 3 to drive the nut 8 of the ball screw pair, so that the two fork bodies 3 rotate relatively to clamp the perpetrator. The two anti-retreat forks 1 rotate inward to resist the perpetrator from the back to prevent him from withdrawing from the fork body 3. Start the air pump 15 to inflate the airbag 2 to assist the two fork bodies 3 to clamp the perpetrator. For the perpetrator holding a steel knife or other lethal weapon, turn on the power supply of the electromagnet 4 to use the electromagnet 4 to adsorb the knife to achieve disarmament. For the perpetrator with fierce resistance, use the damping hinge to adjust the strobe light 21 to aim at the perpetrator, and start the strobe light 21 to irradiate the perpetrator to make him lose the ability to resist for a short time and subdue him.

[0052] After use, turn off the main power switch 25. Open the buckle 192, separate the opening connecting cylinder 191 on the first connecting pipe 19 from the tapered expansion plug 201 on the second connecting pipe 20, and rotate the second fork rod tube 18. The hinge pin 204 slides and rotates in the hinge chute 194, and fold the first fork rod tube 17 and the second fork rod tube 18 for convenient carrying and storage.

[0053] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
