Detailed description of the invention
Below only with embodiment, the enforcement aspect that the present invention is possible is described, but and be not used to limit the present invention institute for protect category, first give chat bright.
Please refer to Fig. 1 to Fig. 6, the invention provides a kind of gunpowder nail, comprise body 10 and a gunpowder 20.
This body 10 has a relative first end and one second end, and this first end place is provided with the rivet nut 11 protruded one day outward, and this second end place is provided with an accommodation chamber 12.In main embodiment of the present invention, this body 10 forms for plastic jetting forming, and first end place is installed with this rivet nut 11 and is incident upon for nail and penetrates object for nail, and the second end is one this accommodation chamber 12 recessed then.
This gunpowder 20 comprises propellant powder 21,1 first percussion charge 22 and a protective layer 23, this propellant powder 21 is the recessed groove 211 in one end wherein, this first percussion charge 22 is located in this groove 211, this protective layer 23 this propellant powder 21 at least coating has one end of this first percussion charge 22 and the opening of this groove 211 at least coating, this first percussion charge 22 is hedged off from the outer world, and this gunpowder 20 can be provided with its one end away from this first percussion charge 22 and be embedded in this accommodation chamber 12; Wherein, the surface area that this propellant powder 21 has the end of this groove 211 is greater than the area of this groove 211 opening.In main embodiment of the present invention, this gunpowder 20 is generally general corresponding with accommodation chamber 12 shape of this body in ingot shape, this propellant powder 21 can be suppressed in modes such as moulds by material powder and form, using the main energy sources as ignition, and be formed with a groove 211 in its one end, this first percussion charge 22 is inserted in this groove 211 and is combined as a whole with this propellant powder 21, this first percussion charge 22 has the characteristic of more easily igniting and can be used as the use of fuse, even, in other possibility embodiments of this case, person as shown in Figure 8, in this propellant powder 21b opposite end, a recessed groove 211 respectively, this first percussion charge 22 and one second percussion charge 24 are inserted in this two groove 211 respectively, whereby, no matter user inserts in the accommodation chamber of body with which end in the opposite end of this gunpowder, all can pull the trigger smoothly.
Be noted that especially, this protective layer 23 this groove 211 opening at least coating is to be hedged off from the outer world this first percussion charge 22, in main embodiment of the present invention, this protective layer 23 is in being directly coated on completely with this first percussion charge 22 by this propellant powder 21, this propellant powder 21 is all hedged off from the outer world with this first percussion charge 22, but in other possibility embodiments of the present invention, as shown in Figure 7, this protective layer 23a also only can have the end, one end of the first percussion charge 22a by coated this gunpowder 20a, make this first percussion charge 22a by properly isolated, this propellant powder 21a is not selectively wrapped by.And this protective layer 23 can be a glued membrane; can first again this propellant powder 21 be inserted in glued membrane housing with this first percussion charge 22 by a shaping glued membrane housing; also or first also can in the coated glued membrane of its outer surface again after this propellant powder 21 shaping and this first percussion charge 22; in principle; the thickness of this protective layer 23 and quality are enough to isolated outside air and prevent gunpowder from dispersing, its thickness should not too thick and make initiation by impact not easily or failure.
On the other hand, this propellant powder 21 establishes a fillet surface 212 to being less than an end ring with this first percussion charge 22, this fillet surface 212 is connected to this propellant powder 21 and has between one end end face of this first percussion charge 22 and the outer ring surface of this propellant powder 21, make the end outer rim of this propellant powder 21 in cutting shape, whereby, this gunpowder can be inserted in this body by user more easily.
By said structure, gunpowder nail provided by the invention can for a gunpowder nail gun percussion, more particularly, this gunpowder nail gun has one end of this first percussion charge by this gunpowder of trigger member fast ram, this protective layer to be broken through or with the high heat fusing that rubs, and then borrow its powerful impulse force to light, ignite this percussion charge, propellant powder around it is lighted ignition by this percussion charge more further, ignite a large amount of gases of producing instantaneously in the inner chamber of gunpowder nail gun by this body toward extrapolated, this body just penetrates outwardly fast with its first end, this rivet nut just can accurately ground nail admittedly to for the solid surface of nail.
In sum; gunpowder nail provided by the invention has the gunpowder independent of each other with rivet nut; and gunpowder has protective layer is hedged off from the outer world by percussion charge; avoid percussion charge and extraneous contact and make moist causing and cannot lighting; also avoid by causing powder four to fall apart during high-speed impact, being difficult to percussion in gunpowder powder can being wrapped in; and gunpowder structure is easy to install, be beneficial to and deposit, and has the effect of progress.
