Abstract

The utility model relates to an electron gun which mainly adopts the batteries to be as the energy resource. An electronic high voltage generator makes two pin-shaped electrodes on the bullets which are connected through the conducting wire have pulsed high voltage, and a trigger starts a spring to eject the bullets in an air pressure mode. The effective distance can reach more than 2.5 m, and two fixed electrodes which are positioned at the gunpoint simultaneously generate pulsed high voltage. The electron gun has the inherent function of the electric baton, the voltage is about ten thousand volt, and the electric current is also smaller than the deadly electric current. The utility model has the advantages of simple structure, easy fabrication, small volume, light weight, convenient carrying and large operating distance.

Description

Electron gun

The utility model belongs to alert use apparatus, specifically a kind of electron gun.

The electric billy that current public security, security department are equipped with is to touch the effect of the other side's competence exertion with its front end.Its major defect is: too short, dangerous big, the poor practicability of operating distance.

The utility model has reasonably solved the too short problem of electric billy operating distance again under the prerequisite of the function that has both kept electric billy.

Structure of the present utility model by: rifle housing, gun barrel, pulling plug, string chamber, village, draw formations such as string, compression spring, chuck, connecting rod, piston, bullet, trigger, battery, electronic component, transformer, power switch, fixed electrode.Its feature has three: the one, and the battery that disposes in the rifle housing made from metal or duroplasts is the energy, uses two needle electrodes on the bullet that lead connects to produce high voltage pulses by the electronics high pressure generator.The 2nd, gun barrel, the pulling plug made from metal or duroplasts, draw string, chuck, connecting rod, piston is as a whole processes.Pulling plug is with drawing string to connect, and passes spring, chuck, connecting rod, piston and connects solid seal.With pulling plug chuck is withdrawn into cocked orientation, the compression spring almost is compressed to the limit.Chuck is blocked automatically by the trigger that torsionspring is housed.Load onto bullet, form an air chamber between itself and the piston, work as cocking, spring promotes piston and penetrates with the bullet with two needle electrodes that the air pressure mode will have lead and pulsed high-voltage.The 3rd, two metal preceding termination electrodes of gun barrel that are fixed on of usefulness are arranged, its rear end is connected with lead and electronics high pressure generator, makes it have the intrinsic function of current electric billy.

High pressure generator be transistor from excitation converting circuit, as shown in Figure 2: comprising being wound with input winding, output winding and positive feedback winding on a transistor, magnetic core, resistance, the magnetic core.Produce electromagnetic coupling between them and close, form self-oscillation.

From the circuit of Fig. 2 as can be seen, sort circuit is by the work of vibration amplification principle.Transistor AND gate magnetic core converter is formed resistance inductance type oscillator, oscillating circuit is constantly obtained energy from dc source, by the positive feedback winding, utilize the nonlinear characteristic of transistorized on-off action and magnetic core to form the alternating voltage that self-oscillation is output as rectangular ripple again, behind the C1D1C2D2 voltage multiplying rectifier, obtained high pressure.

The housing of electron gun can be made with metal or duroplasts.For easy to make, can make with plastics, the thickness of the size of its housing, the length of gun barrel, internal diameter can be decided according to range and function, and gun barrel can be single tube or multitube form.Gun barrel of many increases then need increase the accessory of a cover shooting part.Such as pulling plug, draw string, compression spring, chuck, connecting rod, piston, trigger, bullet etc.Pulling plug, chuck, connecting rod, piston can be made with metal or duroplasts.For easy to make, can make with duroplasts, its diameter will be complementary with the gun barrel internal diameter.Connect the string that draws of pulling plug, piston, its effect has two, and the one, contraction spring is withdrawn into cocked orientation with chuck.The 2nd, the restraining piston does not make it deviate from gun barrel.Bullet can be made with metal or duroplasts, for easy to make.Available duroplasts is made, its diameter will be complementary with the internal diameter of gun barrel, and the lead that connects power supply and electronics high pressure generator is in off state at ordinary times at the power switch place, when trigger is pulled, the little copper sheet displacement that is fixed on the one side is connected (or using microswitch) with the circuit of power switch.Shoot when making two needle electrodes on the bullet have high voltage pulse, reach the uniform criminal or catch enemy's purpose, two fixed electrodes at the muzzle place also have high voltage pulse simultaneously.

The utility model has the advantages that: 1, simple in structure, make easily, cost is low.2, volume short and small, in light weight, be easy to carry.3, the comparable present electric billy of operating distance increases 4-6 doubly, and effective range can reach beyond 2.5 meters.4, have the inherent function of electric billy simultaneously concurrently.
