Abstract

The utility model relates to a pistol and rifle shooting stability analyzing device, which can be used to evaluate the stability of the posture of a shooter holding a gun when aiming at a target and pulling a trigger under the circumstance without live shooting. Moreover, the device can also provide the shooter with timely intuitive azimuth for correcting the posture of the shooter holding the gun. The device integrates a semiconductor laser and a barrel into a whole body. When the device is used to determine the shooting distance, a laser speckle substitutes for an impact point since the laser speckle on the target and the impact point of the target center can determine the shooting distance. A micro switch is arranged on a moving part shooting a bullet. The micro switch is connected with a laser power supply controller. When the trigger is pulled, the micro switch sends a signal of turning off the voltage to the power supply controller, and the power supply controller stops supplying the voltage to the laser. When the trigger returns, the micro switch sends a signal of turning on the voltage, the power supply controller supplies the voltage to the laser and the voltage is increased from zero. A speckle identifying device records the brightness and the position variation of the laser speckle. Thereby, the stability of the aiming action and the shooting action of the shooter is evaluated according to the brightness and the position variation of the speckle.

Description

Pistol riflery stability analysis device

Affiliated technical field

The utility model relates to a kind of pistol riflery stability analysis device, and it is used for gunnery training to the assessment in shooter's aiming and firing position overall process stability.

Background technology

Firm according to rifle, correct consistent aiming, evenly honest triggering pulling and the organic combination of three is the basic fundamental of rifle precision fire.According to rifle stability; The uniformity that keeps correct body position; Persistence and cooperation steady, that take aim at, detain according to the rifle posture are to be engaged in the emphasis of small arms firing personnel training.For the assessment of this technology grasp degree, be by a large amount of ball firing, carry out according to the achievement on the target.In 1991, the patent of invention of " balance and stability test instrument for shooting " (publication number: CN1068271) be suggested.Its operation principle is, the piezo-electric crystal gyro is housed respectively on human body and gun, by the gyro of installing, measure respectively before and after the human body and about; Gun up and down and about rock.This balance and stability test instrument for shooting has following three problems: 1. gyro installation question: human body is not a rigid body, and which position gyro is installed on the human body can represent human body attitude; Piezo-electric crystal gyro volume big (inferior decimetre magnitude), it is difficult on pistol it being installed.2. assess the apparent problem of effect: the result with gyro to measure is an angle, represents aim bias with it.For timely revise directly perceived indicative poor of shooter's attitude.3. to use the sensitivity of piezo-electric crystal gyro be 0.002 degree/s to balance and stability test instrument for shooting, is high-precision aspect sensor.The operation technique of this device is strong, the manufacturing cost height of device.

Summary of the invention

A kind of shooting stability analysis of the utility model device, this device can not only show in real time intuitively the target deviation position when shooter aims at, for shooter intuitively indicates rifle appearance correction orientation, and can write down the situation that shooter shoots overall process stability, particularly to the action real-time calibration of shooter's triggering pulling, the situation of change of rifle appearance when analyzing shooter's triggering pulling.

The technical scheme that its technical problem that solves the utility model adopts is: from view of function, device is divided into bomb-release point indication, percussion calibration and hot spot changes three parts of identification.Bomb-release point indication: on gun barrel, place the semiconductor laser instrument, and make the light beam of laser instrument parallel with gun barrel.Laser instrument is by circuit control power supply.Shooter is when aiming, and the hot spot of laser instrument also drops on target surface.Although the bomb-release point of expecting does not overlap with the hot spot of laser instrument, clear and definite relation is arranged between the two on target.Suppose that bullet goes out thorax speed definite (each production batch bullet performance unanimity) and shooting distance is determined, both distances are changeless.The hot spot of laser instrument is at indicated invariant position, and it is stable representing shooter's aiming; The distance that the bomb-release point of the distance representative expectation that hot spot moves moves.The percussion calibration: the trigger position at shooting gun is provided with miniature switch.Miniature switch is connected with the laser power supply controller.Miniature switch is made up of miniature magnet and mini Hall sensor.When trigger was pulled, the magnet of placing on the trigger moved simultaneously, made Hall element detect the variation in magnetic field, and switch cuts off voltage signal for one of laser power supply controller, and power-supply controller of electric terminates as laser instrument voltage is provided; When trigger returned, switch provided the connection voltage signal, and power-supply controller of electric provides voltage by zero to greatly to laser instrument, and the hot spot brightness of laser instrument is pulled and changed along with trigger.Hot spot changes identification: aiming target adopts transparent material, and the target sheet of aiming usefulness is pasted in the front of target, and the back side draws on transparent material and has scale coordinate line anyhow.The hot spot of laser instrument is penetrated on target, at the back side of target, places a picture pick-up device.Picture pick-up device is noted through image target sheet, transparent target body, that be in hot spot in the coordinate line, simultaneously, is transferred to display by video line, the stable case of action when in time observing aiming for shooter.Hot spot brightness of picture pick-up device writing laser and change in location.According to hot spot brightness and situation, analyze shooter's attitude stabilization situation.

The beneficial effects of the utility model are need not under a large amount of ball firing situations rifle appearance stability when assessment shooter aiming and triggering pulling.Simultaneously, in time indicating the rifle appearance intuitively, shooter should revise the orientation.Structure and operation technique are simple, low cost of manufacture.
