Description

Technical Field

[0001] This utility model relates to the field of police explosion-proof equipment technology, and in particular to a self-protective police explosion-proof fork. Background Technology

[0002] Police riot control forks, also known as riot forks, are equipment tools used by police forces to maintain social order and control violence. They are usually made of high-strength materials, such as steel or aluminum alloy, to ensure their sturdiness and durability. Riot control forks are designed to help police effectively control and confront rioters in violent incidents. They can be used to push, intercept or subdue violent perpetrators, and can also be used to protect police officers from attack.

[0003] Currently, most police riot control forks are designed in a semi-circular shape. This makes them easy for the perpetrator to push away and separate, making it difficult to restrain the perpetrator. This keeps the perpetrator and user at a certain distance, which gives the perpetrator the opportunity to make close contact and poses a danger to the user.

[0004] Therefore, how to design a police riot control fork to prevent the perpetrator from escaping is a technical problem that technicians need to solve. Utility Model Content

[0005] The purpose of this invention is to provide a self-protective police riot control fork. By striking the two grippers with a hammer, the grippers are forced to close, thus securing the perpetrator and preventing their escape. The length of the connecting rod is used to control close contact between the perpetrator and the protector. At the same time, the current generated by the piezoelectric ceramic can shock the riot control protector, numbing them. This effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-protecting police explosion-proof fork, comprising a connecting rod and a mounting base, wherein the connecting rod and the mounting base are connected, and a striking hammer is provided through the inner wall of the mounting base;

[0007] The clamping assembly, located on the inner wall of the mounting base, works in conjunction with the connecting rod to clamp and fix the perpetrator, preventing the perpetrator from escaping and coming into close contact with the user, thus providing protection.

[0008] A limiting ring is located at the middle position of the inner wall of the connecting rod, and a second spring is connected to the end of the limiting ring away from the hammer. A magnetic block is connected to the free end of the second spring, and a cable is connected between the magnetic block and the hammer.

[0009] An electromagnet is located at the end of the connecting rod away from the mounting base.

[0010] Preferably, the clamping assembly includes two jaws rotatably disposed on the inner wall of the mounting base, a damping spring is provided at the rotatable part of the jaws and the mounting base, and a first spring is provided between the two jaws.

[0011] Preferably, each of the two grippers has a piezoelectric ceramic and a set of electrodes on one side wall opposite to the other, and a conductive sheet is provided on one side of the gripper near the electrodes.

[0012] Each set of electrodes includes a positive electrode and a negative electrode, both of which are electrically connected to the piezoelectric ceramic.

[0013] Preferably, the electromagnet and the magnetic block are magnetically repulsive, and the resulting repulsive force is greater than the elastic force of the second spring.

[0014] Preferably, the front end of the hammer is trapezoidal, and the upper surface of the hammer cone is in contact with the top of the mounting base.

[0015] Preferably, a control component is provided at the end of the connecting rod away from the clamping assembly, the control component contains a battery, and an on / off switch is provided on one side wall of the control component.

[0016] Preferably, the length of the cable is the same as the length of the second spring.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: By energizing the electromagnet, the magnetic block rapidly impacts the striking hammer under the action of repulsion, thereby impacting the two grippers and the piezoelectric ceramic, causing the grippers to rotate and close, fixing the attacker and preventing escape. The length of the connecting rod is used to control close contact between the attacker and the protector. At the same time, the current generated by the striking hammer impacting the piezoelectric ceramic, through the interaction between the electrodes and the conductive plate, can shock the attacker, numbing their entire body and making it difficult for them to resist, thus achieving protection for the user. When the user is no longer needed, by de-energizing the electromagnet, the magnetic block returns to its original position under the elastic force of the second spring, and the two grippers rotate back to their original position under the action of the damping spring and the first spring.

[0032] The technical solution of the present utility model embodiment is described in detail below with reference to the accompanying drawings: A self-protecting police explosion-proof fork includes a connecting rod 1 and a mounting base 2, the connecting rod 1 and the mounting base 2 are connected, and a hammer 5 is provided through the inner wall of the mounting base 2;

[0033] The clamping component 3 is set on the inner wall of the mounting base 2 and works with the connecting rod 1 to clamp and fix the perpetrator, thereby preventing the perpetrator from escaping and coming into close contact with the user to achieve protection.

[0034] The limiting ring 6 is located at the middle position of the inner wall of the connecting rod 1, and the end of the limiting ring 6 away from the hammer 5 is connected to the second spring 7.

[0035] Electromagnet 9 is located at the end of connecting rod 1 away from mounting base 2.

[0036] The clamping assembly 3 includes two jaws 31 rotatably disposed on the inner wall of the mounting base 2. A damping spring 34 is provided at the rotatable part of the jaws 31 and the mounting base 2, and a first spring 36 is provided between the two jaws 31.

[0037] Each of the two grippers 31 has a piezoelectric ceramic 35 and a set of electrodes 32 on one side wall opposite to each other, and a conductive sheet 33 is provided on one side of the gripper 31 near the electrodes 32.

[0038] Each set of electrodes 32 includes a positive electrode and a negative electrode, and both the positive and negative electrodes are electrically connected to the piezoelectric ceramic 35.

[0039] The electromagnet 9 and the magnetic block 8 repel each other magnetically, and the repulsive force generated is greater than the elastic force of the second spring 7.

[0040] The front end of the hammer 5 is trapezoidal, and the upper surface of the cone head of the hammer 5 fits against the inner top of the mounting base 2.

[0041] A control component 4 is provided at the end of the connecting rod 1 away from the clamping assembly 3. A battery is provided inside the control component 4, and an on / off switch 11 is provided on one side wall of the control component 4.

[0042] The length of cable 10 is the same as the length of the second spring 7.

[0043] Example 1

[0044] refer to Figures 1 to 6 To address the issue of attackers escaping the explosion-proof fork and coming into close contact with the user during use, the technical solution implemented here is as follows: By energizing the electromagnet 9, the magnetic block 8 rapidly strikes the hammer 5 under the action of repulsion. The hammer 5 then strikes the two grippers 31, causing the grippers 31 to rotate relative to each other and close, thus securing the attacker's chest and waist area. The 1.5-meter length of the connecting rod 1 prevents the attacker from getting close or escaping, avoiding the danger to the user caused by close contact. When the user is no longer needed, by de-energizing the electromagnet 9, the magnetic block 8 quickly returns to its original position under the elastic force of the second spring 7, adhering to the electromagnet 9. Under the elastic action of the damping spring 34 and the first spring 36, the two grippers 31 rotate back to their original position.

[0045] Example 2

[0047] Each set of electrodes 32 includes a positive electrode and a negative electrode, and both the positive and negative electrodes are electrically connected to the piezoelectric ceramic 35. When the hammer 5 strikes, it will also strike the piezoelectric ceramic 35. The current generated will come into contact with the perpetrator's body through the electrodes 32 and the conductive sheet 33, forming a closed circuit and delivering an electric shock to the perpetrator's body, knocking them to the ground with one blow, making the perpetrator numb, limp, and powerless, unable to resist.
