Piezoelectric shock type anti-riot steel fork and output voltage adjusting method thereof

Abstract

The invention discloses a piezoelectric shock type anti-riot steel fork. The piezoelectric shock type anti-riot steel fork comprises a fork handle and a fork head fixedly connected to the top end of the fork handle; a positive-electrode shock needle and a negative-electrode shock needle are fixedly connected to the top end of the fork handle, and a piezoelectric shock mechanism used for supplyingvoltage and currents to the positive-electrode shock needle and the negative-electrode shock needle is arranged in the fork handle; and the piezoelectric shock mechanism comprises a piezoelectric crystal, a voltage amplifier connected with the output end of the piezoelectric crystal, a piezoelectric crystal rapping assembly used for rapping the piezoelectric crystal and a voltage transmitting assembly used for supplying the voltage to the piezoelectric crystal rapping assembly. The invention further discloses an output voltage adjusting method of the piezoelectric shock type anti-riot steel fork. According to the piezoelectric shock type anti-riot steel fork and the output voltage adjusting method of the piezoelectric shock type anti-riot steel fork, design is reasonable, implementation isconvenient, the cost is low, the piezoelectric shock type anti-riot steel fork can be effectively applied to the law enforcement process of law enforcement officers, offenders committing a violent act can be effectively subdued, operation is safe and convenient, the using effect is good, and use and popularization are convenient.

Description

technical field [0001] The invention belongs to the technical field of police equipment, and in particular relates to a piezoelectric electric shock type anti-riot steel fork and an output voltage adjustment method thereof. 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 o...

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
