[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1:

[0024] Reference Figure 1-Figure 2 The explosion-proof fork comprises a fork ring 1, a chain 11 is fixedly mounted on the outer surface of the fork ring 1, an explosion-proof device is arranged on the outer surface of the fork ring 1, and the explosion-proof device comprises a mild steel plate 21, and the mild steel plate 21 is bent under force to restrain a person.

[0025] The explosion-proof device also includes a binding belt 2, which is wrapped around the outer surface of the soft steel plate 21. The outer surface of the binding belt 2 is fixedly installed on one end of the chain 11, and the fork ring 1 is fixedly installed on the outer surface of the support rod 61. By wrapping the soft steel plate 21 with the binding belt 2, it can prevent the soft steel plate 21 from scratching people, and the binding belt 2 can be quickly closed under the force of the soft steel plate 21. When restraining people, it is not easy to break and deform. The binding belt 2 is connected to the fork ring 1 through the chain 11, which can prevent the binding belt 2 from falling. People do not need to hold the explosion-proof fork all the time, freeing their hands.

[0026] Magnetic rings 3 are fixedly installed at both ends of the fork ring 1, and a fixed magnet 31 is fixedly installed on the outer surface of the binding belt 2. The outer surface of the magnetic ring 3 is magnetically connected to the outer surface of the fixed magnet 31. The magnetic connection between the magnetic ring 3 and the fixed magnet 31 can better fix and separate the fork ring 1 and the binding belt 2, making it easy to use.

[0027] Velcro 4 is fixedly installed on both sides of the binding belt 2, and a magnetic film 41 is fixedly installed inside the Velcro 4. An isolation cloth 42 is fixedly bonded to the outer surface of the magnetic film 41, and the outer surface of the isolation cloth 42 is fixedly bonded to the outer surface of the binding belt 2. By installing the Velcro 4, the binding belt 2 can be closed when a person is restrained to prevent the person from breaking free. By installing the magnetic film 41 in the Velcro 4, the magnetic film 41 in the hairy surface and the hook surface of the Velcro 4 are magnetically connected, so that the hairy surface and the hook surface of the Velcro 4 are tightly connected, thereby increasing the fixation of the binding belt 2. By installing the isolation cloth 42, the isolation cloth 42 is made of carbon fiber. Carbon fiber is a non-metallic material with good anti-magnetic properties. It can reduce the penetration and propagation of the magnetic field and prevent the magnetic film 41 from affecting the soft steel plate 21, thereby better closing the binding belt 2.

[0028] Electromagnets 5 are fixedly installed at both ends of the fork ring 1. The electromagnets 5 are located at the center of the magnetic ring 3. When the electromagnets 5 are energized, they will generate the same magnetic field as the fixed magnet 31, thereby repelling it, so that the binding belt 2 generates a forward impulse under the action of the repulsive force. After contacting with a person, the speed at which the soft steel plate 21 wraps the person is accelerated. When using the explosion-proof fork, the person can be restrained only when the binding belt 2 is close to the person. After the electromagnet 5 is powered off, the magnetic ring 3 is magnetically connected to the fixed magnet 31 to better restrain the person.

[0029] By setting up an explosion-proof device, when using the explosion-proof fork to restrain a person, the binding belt 2 is quickly closed under the force of the soft steel plate 21, and the magnetic film 41 in the furry surface and the hook surface of the Velcro 4 is magnetically connected, so that the furry surface and the hook surface of the Velcro 4 are tightly connected, thereby increasing the fixation of the binding belt 2, and the isolation cloth 42 can prevent the magnetic film 41 from affecting the soft steel plate 21, thereby solving the problem of easy escape when using the explosion-proof fork based on the existing technology, and the main rod is inconvenient to carry due to length limitations, which is not conducive to practical use.

[0030] Working principle: When using the explosion-proof fork, bring the binding belt 2 on the fork ring 1 close. After the electromagnet 5 is energized, it will generate the same magnetic field as the fixed magnet 31, thereby repelling it, which can make the binding belt 2 generate impact force to bind the other party. The magnetic film 41 in the hook surface and the Velcro 4 are magnetically connected to make them tightly adhered. The isolation cloth 42 prevents the magnetic film 41 from affecting the soft steel plate 21. After the electromagnet 5 is powered off, the magnetic ring 3 and the fixed magnet 31 are magnetically connected to fix the fork ring 1 and the binding belt 2.

[0031] Embodiment 2:

[0032] Reference Figure 3-Figure 4The explosion-proof fork comprises a fork ring 1, a chain 11 is fixedly mounted on the outer surface of the fork ring 1, a telescopic device is arranged on the outer surface of the fork ring 1, and the telescopic device comprises a support rod 61. The movement of the support rod 61 raises and lowers the explosion-proof device.

[0033] The telescopic device also includes a sleeve 6, which is slidably sleeved on the outer surface of the support rod 61, and the support rod 61 is fixedly installed on the outer surface of the fork ring 1. The fork ring 1 is raised and lowered by installing the support rod 61 and moving the support rod 61. The sleeve 6 is slidably sleeved on the outer surface of the support rod 61, which can prevent the sleeve 6 from shaking during the lifting of the support rod 61, thereby improving stability and avoiding affecting the use effect.

[0034] The outer surface of the sleeve 6 is rotatably connected to a handle 7, one end of the handle 7 is fixedly installed with a threaded rod 71, the outer surface of the threaded rod 71 is threadedly connected to the inner wall of the support rod 61, the inner wall of the support rod 61 is slidably inserted with a circular plate 72, the outer surface of the circular plate 72 is fixedly installed with one end of the threaded rod 71 through a bearing, and the handle 7 is installed. The handle 7 is a threaded style to prevent hand slippage during use and affect the use effect. The threaded rod 71 is threadedly connected to the inner wall of the support rod 61, and when the handle 7 is twisted, the support rod 61 can be driven to rise and fall, thereby driving the fork ring 1 to rise and fall. The threaded rod 71 is supported by the slidably inserted circular plate 72 to prevent the support rod 61 from shaking during the lifting process and affecting the use effect.

[0035] By setting a telescopic device, the explosion-proof device can be raised and lowered, and the sleeve 6 is slidably sleeved on the outside of the support rod 61 to prevent shaking during the lifting process. The handle 7 is a threaded style to prevent hand slippage during use. The threaded rod 71 is threadedly connected to the inner wall of the support rod 61, and the handle 7 can be twisted to drive the support rod 61 to be raised and lowered, thereby driving the fork ring 1 to be raised and lowered. The threaded rod 71 is fixed by sliding and plugging the circular plate 72 to prevent the support rod 61 from shaking, thereby solving the technical problems based on the existing explosion-proof forks that are easy to break free when used, and the main rod is inconvenient to carry due to length restrictions, which is not conducive to actual use.

[0036] Working principle: when the explosion-proof fork needs to be adjusted, the handle 7 is twisted, and the threaded rod 71 is rotated on the circular plate 72, so that the support rod 61 threadedly connected to the threaded rod 71 is lifted and lowered on the inner wall of the sleeve 6.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
