Abstract

A volleying civilian gun with a reduction gear mainly comprises a blocking mechanism, an ejection mechanism, an ammunition feeding mechanism, a firing mechanism, a shooting mechanism and a cartridge receiver. The volleying civilian gun with the reduction gear is characterized in that the reduction gear formed by an impacting block, a reducer base, a reducer shaft and a reducer spring is additionally arranged in the shooting mechanism. A shaft hole matched with a shaft of the firing mechanism is formed in the reducer base. The reducer base is fixed on the shaft of the firing mechanism through the shaft hole. The impacting block is fixed on the upper portion of the reducer base through the reducer shaft. The impacting block contacts with a driving hammer in the moving process. A reducer spring clamping groove is formed in the impacting block. The reducer spring is a torsional spring which is sleeved on the shaft of the firing mechanism, one end of the reducer spring is fixed in the clamping groove in the impacting block, and the other end of the reducer spring is pressed on the lower plane of a trigger in the shooting mechanism. Due to the fact that a set of reducer gear is added on the volleying civilian gun, the driving hammer can delay a few milliseconds to move forward in the next firing so as to ensure that the whole gun is in a stable state and then shoots a firing pin after a bolt carrier completely stops, and accordingly the volleying civilian gun improves reliability and accuracy in the volleying shooting of firearms.

Description

The running fire civil-use gun that has deceleration device

Technical field

The utility model belongs to civil-use gun, especially belongs to the civil-use gun that needs deceleration device.

Background technology

Civil-use gun based on the AK system mainly comprises blocking mechanism 6 in early days, cartridge case extractor, ammunition feed mechanism, firing lock 4, trigger mechanism 5, casing etc., its percussion, the primary structure of trigger mechanism such as Fig. 1, shown in 2, deferred mount does not slow down in the trigger mechanism, after last bullet percussion when continuous fire, can occurring, after breech housing 61 recoils in the blocking mechanism also enter the position again, hammer 41 in the firing lock just can be pulled the trigger once more, but because breech housing 61 enters a Collision gun base again and occurs often twice or thrice slightly knock-oning, the gunlock 62 that drives in the blocking mechanism moves forward and backward, the firing pin 42 of hammer 41 from beginning and gunlock 62 touched and promotes this segment distance shortening that firing pin moves to the gunlock afterbody when this caused pulling the trigger, the energy that makes hammer pass to firing pin reduces, this AK series of needs necessarily being pulled the trigger the fire in a stove before fuel is added of intensity often influences the reliability and precision (the floating type firing pin of AK series employing of next bullet shooting, firing pin contacts in advance with the fire in a stove before fuel is added), even can cause AK-47 to occur the phenomenon of failing to explode by accident.

Summary of the invention

The utility model purpose is to overcome the shortcoming that above-mentioned civil-use gun exists, and a kind of deceleration device that can improve the civil-use gun of shooting reliability and precision is provided.

The technical scheme that the utility model adopted is a kind of running fire civil-use gun that has deceleration device, mainly comprise blocking mechanism, cartridge case extractor, ammunition feed mechanism, firing lock, trigger mechanism, casing, its main points are, in trigger mechanism, be added with by impact block, the decelerator seat, reducer shaft, the deceleration device that the decelerator spring is formed, the axis hole that matches with the firing lock axle is arranged on the decelerator seat, the decelerator seat is fixed on the firing lock axle by axis hole, impact block is fixed in the top of decelerator seat by reducer shaft, impact block contacts with hammer in motion process, have decelerator spring draw-in groove on the impact block, the decelerator spring is that torsion spring is placed on the firing lock axle, one end is fixed in the draw-in groove on the impact block, and the other end is pressed in the lower plane of the trigger in the trigger mechanism.

The utility model improves the trigger mechanism of existing firearms, increase by a cover deceleration device, make when pulling the trigger hammer postpone several milliseconds travels forward next time, after guaranteeing that breech housing stops fully, full rifle is in and hits firing pin when stablize again, improves reliability and precision when having civilian firearms burst-firing based on the AK system now.

Wherein: 4 firing locks, 41 hammers, 42 firing pins, 43 mainsprings, 44 firing lock axles, 5 trigger mechanisms, 51 triggers, 55 running fire machines, 57 decelerator seats, 571 axis holes, 58 impact blocks, 581 draw-in grooves, 59 decelerator springs, 510 reducer shafts, 6 blocking mechanisms, 61 breech housings, 62 gunlocks.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail, can makes the professional and technical personnel more understand the utility model, following embodiment is made amendment, it all is possible adding and replacing, and does not all exceed protection domain of the present utility model.

As Fig. 3,4,5, shown in 6, a kind of running fire civil-use gun that has deceleration device, mainly comprise blocking mechanism 6, cartridge case extractor, ammunition feed mechanism, firing lock 4, trigger mechanism 5, casing etc., in trigger mechanism 5, be added with by impact block 58, decelerator seat 57, reducer shaft 510, the deceleration device that decelerator spring 59 is formed, the axis hole 571 that matches with firing lock axle 44 is arranged on the decelerator seat 57, decelerator seat 57 is fixed on the firing lock axle 44 by axis hole 571, impact block 58 is fixed in the top of decelerator seat 57 by reducer shaft 510, impact block 58 contacts with hammer 41 in motion process, have decelerator spring 59 draw-in grooves 581 on the impact block 58, decelerator spring 59 is placed on the firing lock axle 44 for torsion spring, one end is fixed in the draw-in groove 581 on the impact block 58, and the other end is pressed in the lower plane of the trigger 51 in the trigger mechanism.

When burst-firing, breech housing enters the position again and frees running fire machine 55, the no longer interlock of running fire machine and hammer, hammer 41 begins revolution under the mainspring effect, hammer 41 clashes into the impact block 58 of deceleration device, rub with decelerator seat 57 then, break away from deceleration device at last and impact firing pin 42.
