Description

powder gun structure

The present invention relates to a structure of a powder gun; in particular, to a structure of a powder gun which can maintain the maximum force of each firing under continuous firing, and can control the included angle between the gun case and the gun body.

According to the gunpowder nail gun, it is a nailing tool that uses the principle of gunpowder explosion to push the nail rod once, and can hit the nail body into a rigid target.

Since the firing power of the gunpowder nail gun is quite powerful, if there is a wrong firing action when facing the air (that is, the state of facing the void without touching any physical target), the force of the nail body will inevitably cause serious damage to people and objects. Therefore, the current gunpowder nail gun product series will be specially designed for the use of safety issues to reduce the probability of accidental danger.

Furthermore, before the conventional gunpowder nail gun is fired, it is necessary to keep the gun mouth up for several seconds, and then the piston part of the nailing rod can be slowly slid to the original position of the piston cylinder by the action of gravity (i.e. is ready to be fired), and then put a single nail into the near end of the pipe of the gun nozzle, and finally, press the trigger again so that the firing pin impacts the gunpowder and produces an explosive force, so that the nail bar will produce an instant impact action (that is, the piston part of the nailing rod quickly moves to another position after shooting of the piston cylinder) so that the nails pre-accommodated at the end of the pipeline can be driven into the target; stay for a few seconds When the trigger is pressed again, although the trigger can control the firing pin to impact the gunpowder to generate an explosive force, the explosive force is only just enough to fill the piston cylinder, and cannot push the nail rod to move again, resulting in an invalid firing phenomenon; As a result, it not only can only fill one nail into the pipeline at a time, so that it is quite inconvenient to operate and use, but also cannot be used for continuous firing, which reduces its construction efficiency. Insufficient dwell time will reduce the driving force of the nailing rod, and the nail head cannot be buried into the surface of the target object, so that the protruding nail head is likely to cause accidental danger of scratching others Happened as a major problem.

Therefore, in view of the above-mentioned problems existing in the structure of the conventional gunpowder nail gun, how to develop a more ideal and practical innovative structure is what users expect, and it is also the goal and direction that related companies must work hard to develop breakthroughs.

Based on this, when the gun nozzle group is pressed and moves into the gun body (that is, retracted), the ball will be simultaneously pressed by the inner wall surface of the pressed part (that is, the inclined plane design) ) and the synchronous clamping and pressing action of the outer surface of the nailing rod to form an integral shape, so that the nailing rod can move with the gun nozzle group, and can make the The piston portion of the nailing rod can be accommodated and slid to the initial position in the piston cylinder of the movable piston cylinder base (that is, the best ready-to-fire state), and can maintain the power of each firing under continuous firing. To maximize, so that the nail head after being hit can be buried below the surface of the target object without the accidental risk of scratching others. It is an advanced proposition.

As shown in Figure 4, they are 3 pairs of nozzle bodies of the gunpowder nail gun Empty state, in this state, the movable piston cylinder seat 70 and the push rod 75 are in the preset forward state, and the driven projection 52 of the rotatable firing pin 50 and the firing actuating part of the firing linkage plate 43 are staggered. Therefore, even if we press the button part 21 of the trigger group 2 to make the firing linkage plate 43 swing, since the firing actuation part cannot push against the driven projection 52, and the rotatable firing pin 50 has no accumulated momentum, Therefore, it is impossible to produce a nailing action, so that the disclosed powder nail gun has the safety protection function of preventing false strikes in the air.

Please refer to Fig. 5, when the end of the gun barrel 31 of the gun mouth body 3 is pressed against the target 92 and retracted (that is, moved to the right), although it will make the base portion of the gun mouth body 3 The collar piece 38 on the outer peripheral side of 30, the pressing piece 36 already located in the cavity 301 of the base part 30, the elastic piece 37 sandwiched between the inner wall surface of the collar piece 38 and the outer wall surface of the pressing piece 36 , and the ball 35 that has been sandwiched between the inner wall of the pressed part 36 and the elongated hole 302 will move to the right side along with the barrel 31, and in addition, it has been located at the base of the nozzle body 3 A part of the ball 35 in the elongated hole 302 of 30 protrudes into the pipe 32, and the part of the ball 35 that has protruded into the pipe 32 will touch the outer surface of the nail rod 80, and make The other part of the ball 35 will not be pressed by the inner wall surface of the pressing part 36 at all (i.e. there is a gap or no contact shape); therefore, in the process of moving, at first, the base portion 30 of the nozzle body 3 The receptacle 301 will simultaneously drive the pressed part 36 and the elongated hole 302 to move to the right side together, and the ball 35 (because the ball 35 is not in contact with the pressed part 36 ) is initially only subjected to the friction of the driving rod 80 resistance and will not move with the pressing part 36 until the surface of the pressing part 36 and the driving rod 80 At the same time, the ball 35 is sandwiched (that is, the ball 35 has moved to the near left side of the pressing part 36) at different positions; moreover, if it continues to press against the target 92 and retract (that is, move to the right again) , the pressing part 36, the ball 35 and the nailing rod 80 can be moved to the right side together until the piston part 82 of the nailing rod 80 is moved to the right side near the piston cylinder 71 (ie starting position) to form an optimal ready-to-fire state;

Then, as shown in Figure 6, continuing the state of the muzzle body 3 being pressed and retracted as described in the previous paragraph, if we press the button portion 21 of the trigger unit 2 at this time to impel the firing linkage plate 43 to swing, then the firing will cause The moving part will be able to push against the driven projection 52 to produce an upward radial offset, and once the driven projection 52 deviates, the impact elastic force accumulated by the rotatable striker 50 due to the compression of the pre-compressed elastic member 51 will be instantaneous. is released, causing the rotatable firing pin 50 to produce an impact action forward, causing the rotatable firing pin 50 to hit the powder row 410, and causing the powder row 410 to be detonated. The piston portion 82 in the cylinder 71 drives the nailing rod 80 to impact forward, and uses its striking end 81 to drive the nail 91 already positioned in the pipe 32 into the target 92, thereby achieving the nailing action. ;

Please refer to Fig. 7, when the construction site is limited, it is only necessary to apply force to press the gun case 90 to move in the direction of the gun body 1 (that is, retract or move to the right, and the gun case 90 is locked at the gun mouth body 3), so that the gun case 90 will drive the base portion 30 of the gun mouth body 3 to move in the chamber 131 of the spacer sleeve 13, and the The concave hole 303 at the bottom end surface of the seat portion 30 is completely disengaged from the end of the adjustment member 15 that has been assembled at the screw hole 133 of the limiting sleeve 13, In other words, the adjustment member 15 will not abut against the concave hole 303, so that the base portion 30 of the nozzle body 3 can freely make any angle with the axis hole 132 of the limiting sleeve 13 as the center. until any one of the inner concave holes 303 on the bottom surface of the base part 30 is aligned with the adjustment member 15, then the inner concave holes 303 can be pushed to the sleeve by a spring 34. At the end of the adjustment piece 15 (that is, the end of the adjustment piece 15 is against the inner hole 303), in this way, it not only enables the gun case 90 and the muzzle body 3 to be positioned between the limit sleeve 13 In addition to the control function of the rotation angle in the chamber 131, at the same time, the angle between the gun case 90 and the handle portion 110 of the gun body 1 can also be changed, so that it is suitable for construction in different fields, thereby greatly improving its competitors.
