A method for adjusting the output voltage of a piezoelectric electric shock type anti-riot steel fork

Abstract

The invention discloses a method for adjusting the output voltage of a piezoelectric electric shock type anti-riot steel fork. The piezoelectric electric shock type anti-riot steel fork includes a fork handle and a fork head fixedly connected to the top of the fork handle, and the top of the fork handle is also fixedly connected with a positive pole. The electrode needle and the negative electric shock needle are provided with a piezoelectric electric shock mechanism for providing voltage and current for the positive electrode needle and the negative electric shock needle in the fork. The piezoelectric electric shock mechanism includes a piezoelectric crystal and a voltage connected to the output terminal of the piezoelectric crystal. An amplifier, a piezoelectric crystal tapping assembly for tapping the piezoelectric crystal, and a pressure transmission assembly for providing pressure to the piezoelectric crystal tapping assembly. The invention has reasonable design, convenient realization and low cost, can be effectively applied in the law enforcement process of law enforcement personnel, and can effectively subdue criminals committing violence.

Description

technical field [0001] The invention belongs to the technical field of police equipment, and in particular relates to a method for adjusting the output voltage of a piezoelectric electric shock type anti-riot steel fork. Background technique [0002] Our country is in a period of social transformation, various social contradictions are prominent, the polarization between rich and poor is intensified, and violent crimes have increased significantly, showing the characteristics of suddenness, passion, and violence. For a long time, in the process of controlling and arresting violent criminals with knives and weapons, police law enforcement personnel such as public security and armed police have lacked suitable and ideal control and arrest equipment due to restrictions on the use of weapons, which has repeatedly led to mission failures or caused some unnecessary incidents. casualties. Anti-riot steel fork is a kind of non-personal contact control equipment. It is composed of "...

AI Technical Summary

Problems solved by technology

Existing electric-shock type anti-riot steel fork is the same as most electric shock weapons, and mainly adopts battery power supply, and battery-powered anti-riot fork has its limitation: one, the number of times of use is limited, and the number of times of use of battery-powered electric shock weapons is mainly determined by battery capacity, and battery capacity The bigger it is, the more times it will be used, and the shape of the steel fork determines that the capacity of the battery should not be too large, so the number of times it can be used for discharge is limited, and its continuous working ability is limited and not strong; second, there are potential safety hazards. Traditional batteries are used in high-temperature environments. The risk of explosion and spontaneous combustion; the third is the complex structure of the working circuit, and traditional rechargeable batteries generally have special protection circuits to prevent overcharging or over-discharging; the fourth is polluting the environment, and it is difficult to dispose of used batteries, which is prone to pollution
