Description

Automatic catching hammer air gun

Automatic hand-up hammer pneumatic gun belongs to the entertainment sports goods, belongs to the pneumatic gun class.Pneumatic gun mainly is made up of gun barrel, body, sighting system, gas charging system, trigger system.

Existing pneumatic gun discharges Compressed Gas by hammer bump exhaust plug plumb is hit, and every shooting once just will be drawn hammer No. one time with hand-power, hammer is in treats percussion state (being called on-hook), and this will exert, and take time, and Firing Velocity has slowed down.

In order to overcome the hand-power on-hook, accelerate Firing Velocity.The utility model proposes new design--automatic hand-up hammer pneumatic gun.Its objective is with the Compressed Gas on-hook and replace artificial on-hook.

Automatic hand-up hammer pneumatic gun as the on-hook of powered hammer, replaces manual operations with Compressed Gas.Compressed Gas is from the gas pressure mechanism of pneumatic gun or the gas cylinder of air-stored pneumatic gun.When the principle of automatic hand-up is shooting, the Compressed Gas shunting in the pneumatic gun gas dome, most of gas enters gun barrel and hits plumb, and a very little part promotes hammer and moves arrival hook position on-hook.

Automatic hand-up hammer pneumatic gun structure is divided into two big effect parts.Shoot on-hook the initial first time that act as of part structure, because also do not carry out shooting.Do not have Compressed Gas in the pneumatic gun gas dome,, carry out on-hook by manpower so do not have gas as the power automatic hand-up.This part-structure is: have movable pin (5) to be installed in main body (8) rectangular slot, drive hammer (6) with the movable pin of hand push (5) moves backward, arrive sear (13) withstands till the hammer (6) always, be hook state this moment, promptly treat the percussion state, another part structure has the automatic hand-up effect.This a part of structure is improved on the trigger system of existing hammer formula pneumatic gun, blow-by between exhaust core (16) on the automatic hand-up hammer pneumatic gun and the hole on the exhaust flange (3), but between the hole of exhaust core and exhaust flange certain interval is arranged, so that when percussion, the sub-fraction Compressed Gas is entered in the cylinder on exhaust flange the right, this part Compressed Gas promotes the mobile hammer of piston (4) (6) and arrives sear (13) on-hook.

Now illustrate the structure and the effect of automatic hand-up hammer pneumatic gun with an embodiment.

Fig. 1 is an automatic hand-up hammer pneumatic gun phantom;

Fig. 2 is an automatic hand-up hammer pneumatic gun A-A profile;

Fig. 3 is an automatic hand-up hammer pneumatic gun part hammer cutaway view;

Fig. 4 is the front view of automatic hand-up hammer pneumatic gun part sear;

Fig. 5 is the right view of automatic hand-up hammer pneumatic gun part sear.

The major part that automatic hand-up hammer pneumatic gun has the on-hook effect has (see figure 1) exhaust flange (3), exhaust core (16), piston (4), movable pin (5), hammer (6), sear (13), sheet spring (15).Exhaust flange (3) is fixed in the air chamber (2), and difference is porose to communicate with gun barrel (1) endoporus and piston (4).Piston (4) is movingly with exhaust flange (3) endoporus, and its end is with piston spring (19), and exhaust core (16) inserts on piston (4) endoporus, and cooperates with exhaust flange (3), is matched in clearance.Hammer (6) (Fig. 3) is installed in the pneumatic gun main body (8), one end in contact piston spring (19), and the other end connects hammer spring (7).Hammer (6) is by sear (13) and plate machine (11) fastening (on-hook), sear (13) is installed in the pin (14) that is fixed in the main body (8) by slot and goes up (Fig. 2,4,5), and can move and rotate along pin (14) is upper and lower, sear (13) has sheet spring (15) to compress.Movable pin (5) is installed in the slot of main body (8), and can move.

The use of automatic hand-up hammer pneumatic gun is as follows.During initial the percussion for the first time, move movable pin (5) with hand and promote hammer (6) overcome friction and hammer spring resistance toward moving to right, make hammer withstand on sear (13) end face, this moment leaf spring bearing and compress sear, it is moved down, and sear is subjected to the restriction of position-limitting pin (12) simultaneously, is unlikely around pin (14) rotating counterclockwise, so sear is not having to be in stable state under the external force effect, thereby the hammer generation fire of also can not advancing.Shake the gas pressure mechanism (not shown) or connect to go up gas cylinder (18) and make in the air chamber (2) and be full of pressed gas, just can shoot after loading onto plumb, cocking (11), force sear (13) to move down, after sear and the disengaging of hammer (6) end face, under the effect of hammer spring (7) power, hammer compression piston spring (19) push piston (4) is turned left and is advanced, and drive exhaust core (16) is pushed air bleeding valve (17) open, compressed air enters exhaust flange (3) in air chamber this moment (2), and wherein most of gas enters gun barrel (1) and hits the plumb shooting.Another fraction gas arrives piston (4) by gap between exhaust core (16) and the exhaust flange (3), promoting piston (4) overcome friction and spring resistance makes hammer (6) be shifted to the right to the hook position, sear moved in sheet spring (15) effect down and withstood hammer (6) this moment, and trigger (11) resets under trigger spring (20) acts on and treats firing position.So far, finish the on-hook action, need not use the hand-power on-hook.If will adjust the impulsive force of hammer (6), can adjust the adjustment screw (10) on the spring base (9).

Automatic hand-up hammer pneumatic gun is simple in structure, and easily processing is installed, and keeps in repair easy to use, reliable, automatic hand-up is finished simultaneously with the percussion plumb, and is reliable rapidly, alleviated muscle power, saved the hand-power on-hook time, improved firing operation speed, and laid the foundation for pulling the trigger continuously.
