Description
Technical Field
The invention relates to a nail striking tool, in particular to a structure of a powder nail gun.
Background
The powder nail gun is a nail striking tool which can strike a nail body into a rigid target object by pushing a nail striking rod by utilizing the principle of powder explosion.
Because the firing power of the powder nail gun is quite powerful, if the firing is mistakenly performed when the nail is empty (i.e. the nail is not collided with any solid target object and is in a virtual empty state), the force of the nail body ejection inevitably causes serious damage and destruction to personnel and objects, and great safety concerns are caused, so that the current powder nail gun product is designed by considering the problem of safe use particularly so as to reduce the occurrence probability of accidental risks.
Furthermore, before the existing powder nail gun is fired, the gun nozzle needs to stay upwards for several seconds, so that the piston part of the nail striking rod can slowly slide to the original position of the piston cylinder (namely, the nail striking rod is in a state of waiting to be fired) under the action of gravity, then a single nail is placed into the near end of the pipeline of the gun nozzle, and finally, the trigger is pressed to enable the firing pin to impact the powder to generate explosive acting force, so that the nail striking rod generates instant impact action (namely, the piston part of the nail striking rod rapidly moves to the position of the piston cylinder after another shot) and can strike the nail accommodated in advance at the tail end of the pipeline into a target object; at the moment, if the gun nozzle stays upwards for several seconds, the trigger is pressed again, although the trigger can control the firing pin to impact gunpowder to generate explosive acting force, the explosive acting force just fills the piston cylinder and is already, and the firing pin rod cannot be pushed again to move, so that the phenomenon of invalid firing is caused; therefore, not only can only fill one nail into the pipeline each time, so that the operation and the use are very inconvenient, but also the continuous percussion use can not be carried out, thereby reducing the construction efficiency, and simultaneously, the insufficient time of the upward stay of the gun nozzle before each percussion can reduce the percussion force of the nail striking rod, and the nail head of the nail can not be really embedded into the surface of the target object, so that the projecting nail head is easy to have the accidental risk of scratching other people, which is a great trouble.

through the above structural design, the operation of the present invention will be described as follows:
as shown in FIG. 4, the gun nozzle body 3 of the powder nail gun is in an empty state, in this state, the movable piston cylinder seat 70 and the push rod 75 are in a preset advancing state, and the actuated protrusion 52 and the firing actuation part of the firing linkage plate 43 are in a staggered and misaligned state, so that even if the button part 21 of the trigger set 2 is pressed to cause the firing linkage plate 43 to swing, the firing actuation part cannot push against the actuated protrusion 52, and the rotatable firing pin 50 has no accumulated impact force, the firing action cannot be generated, and the disclosed powder nail gun has a safety protection function for preventing the air from being mistakenly struck.
Referring to fig. 5, when the end of the barrel 31 of the muzzle body 3 is pressed toward the target 92 to be retracted (i.e. moved to the right), the collar member 38 fitted around the outer peripheral side of the base portion 30 of the nozzle body 3, the pressing member 36 located in the pocket 301 of the base portion 30, the elastic member 37 sandwiched between the inner wall surface of the collar member 38 and the outer wall surface of the pressing member 36, and the balls 35 sandwiched between the inner wall surface of the pressing member 36 and the elongated holes 302 move together with the barrel 31 toward the right side, and in addition, a part of the balls 35 located in the elongated holes 302 of the base portion 30 of the nozzle body 3 protrudes into the duct 32, and part of the ball bearings 35 which protrude into the pipeline 32 can be touched on the outer surface of the nail striking rod 80, and the other part of the ball 35 is not pressed by the inner wall surface of the pressing piece 36 (namely, a gap is formed or the ball is not contacted); therefore, during the moving process, firstly, the accommodating groove 301 of the base portion 30 of the muzzle body 3 simultaneously drives the pressing member 36 and the elongated hole 302 to move to the right side, and the ball 35 (because the ball 35 is not in contact with the pressing member 36) is initially only subjected to the frictional resistance of the nailing rod 80 and does not move along with the pressing member 36 until the pressing member 36 and the nailing rod 80 simultaneously sandwich the ball 35 (i.e. the ball 35 has moved to the near left side of the pressing member 36) at different positions; furthermore, if the pressing member 36, the ball 35 and the nail striking rod 80 are continuously pressed and retracted (i.e. moved to the right) toward the target 92, the pressing member, the ball 35 and the nail striking rod 80 are moved to the right until the piston portion 82 of the nail striking rod 80 is moved to the right of the piston cylinder 71 (i.e. the starting position) to form an optimal cocked state;
then, as shown in fig. 6, the muzzle body 3 is pressed to the inner contracted state continuously, if we press the button portion 21 of the trigger set 2 to swing the trigger linkage plate 43, the trigger actuation portion will push the driven protrusion 52 to generate an upward radial deflection, and once the driven protrusion 52 deflects, the impact resilience of the rotatable firing pin 50 accumulated by the compression of the pre-pressure resilient member 51 is released instantaneously, so that the rotatable firing pin 50 generates an impact action forward, so that the rotatable firing pin 50 will impact the explosive row 410, and the explosive row 410 will be detonated, and the explosive force thereof will push the piston portion 82 already located in the piston cylinder 71 through the interface 72, and drive the striking pin 80 to impact the nail 91 already located in the conduit 32 to the target 92 by using the impact end 81 thereof, thereby achieving the nail striking action;
referring to fig. 7, when the construction site is limited, only the force is applied to press the magazine 90 to move toward the gun body 1 (i.e. to retract inward or move toward the right side, and in addition, the magazine 90 is locked at the gun nozzle body 3), so that the magazine 90 will drive the base portion 30 of the gun nozzle body 3 to move in the containing chamber 131 of the position-limiting sleeve seat 13, and will make the inner concave hole 303 located at the bottom end surface of the base portion 30 completely separate from the end of the adjusting member 15 assembled at the screw hole 133 of the position-limiting sleeve seat 13, in other words, the adjusting member 15 will not abut against the inner concave hole 303, so that the base portion 30 of the gun nozzle body 3 can freely rotate at any angle with the shaft hole 132 of the position-limiting sleeve seat 13 as the center, until any inner concave hole 303 of the bottom end surface of the base portion 30 aligns with the adjusting member 15, the inner concave hole 303 can be pushed by the reaction of the spring 34 to be sleeved at the end of the adjusting member 15 (i.e. the end of the adjusting member 15 abuts against, therefore, not only the magazine 90 and the nozzle body 3 can have the function of controlling the rotation angle in the accommodating chamber 131 of the retainer 13, but also the included angle between the magazine 90 and the grip portion 110 of the gun body 1 can be changed, so that the gun is suitable for construction in different fields, thereby greatly improving the competitiveness.
