Description
Technical field
This utility model relates to screw shooter technical field, especially relates to the silencing means of a kind of screw shooter.
Background technology
Screw shooter is firing pin to penetrate firing pin sleeve pipe and then ignites ammunition head by compressing to fire after spring, the object such as building body or steel plate squeezed into by nail by the powerful thrust that the blast of ammunition head produces, owing to the flow at high speed of air-flow can be produced when ammunition head is ignited, bigger noise phenomena can be caused, working environment noise pollution is serious, also affect periphery social environment, need to improve.
Utility model content
The purpose of this utility model is in that to overcome above-mentioned the deficiencies in the prior art, it is provided that the silencing means of a kind of screw shooter, the noise produced when significantly reducing screw shooter work.
nullFor reaching above-mentioned purpose，The technical solution of the utility model is: the silencing means of a kind of screw shooter，Including nail sleeve pipe，The center of described nail sleeve pipe is provided with axial through hole，The firing pin sleeve pipe of nail and hollow it is provided with in described through hole，It is provided with firing pin in described firing pin sleeve pipe，The head of a nail end of described nail stretches in the ammunition head of cylinder，Described ammunition head and firing pin sleeve pipe abut，The outer wall of described nail sleeve pipe is interval with front flange and rear flange，The front end of nail sleeve pipe is spirally connected noise reduction set，The rear end face of described noise reduction set abuts the front end face of rear flange，The inwall of noise reduction set abuts the outer face of front flange，Noise reduction set、Front flange and rear flange crowd around formation cavity volume，Described nail sleeve pipe is provided with the circular bloop that the uniform diameter of circumference is 1.5mm，Described bloop connection cavity volume and through hole，The inner termination of bloop is positioned at the front end face place of ammunition head，The external end head of bloop is positioned at the middle of front flange and rear flange，The angle of bloop and horizontal direction is 38 degree.
The ailhead end of described nail stretches out through hole.
The quantity of described bloop is three.
The beneficial effects of the utility model are: the high velocity air that ammunition head explosion time produces directly can enter cavity volume from bloop, the noise produced when significantly reducing screw shooter work, and the Position Design of bloop is reasonable simultaneously, good muffling effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the side view of nail sleeve pipe of the present utility model.
In figure: nail sleeve pipe 1, through hole 11, bloop 12, rear flange 13, front flange 14, noise reduction set 2, firing pin sleeve pipe 3, firing pin 4, nail 5, ammunition head 51, cavity volume 6.
Detailed description of the invention
By the examples below, and in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
Such as Fig. 1, shown in Fig. 2, a kind of silencing means of screw shooter, including nail sleeve pipe 1, the center of described nail sleeve pipe 1 is provided with axial through hole 11, the firing pin sleeve pipe 3 of nail 5 and hollow it is provided with in described through hole 11, it is provided with firing pin 4 in described firing pin sleeve pipe 3, the head of a nail end of described nail 5 stretches in the ammunition head 51 of cylinder, the ailhead end of described nail 5 stretches out through hole 11, described ammunition head 51 and firing pin sleeve pipe 3 abut, use screw shooter only need to face toward the ailhead end of the object such as building body or steel plate extruding nail 5, nail 5 drives firing pin sleeve pipe 3 grade to bounce back backward and extrudes percussion spring (not shown in FIG.), firing pin 4 is penetrated firing pin sleeve pipe 3 until triggering percussion spring and then ignites ammunition head 51, nail 5 is squeezed into building body or steel plate by the thrust that ammunition head 51 blast produces.
The outer wall of described nail sleeve pipe 1 is interval with front flange 14 and rear flange 13, nail sleeve pipe 1 front end be spirally connected noise reduction set 2, the rear end face of described noise reduction set 2 abuts the front end face of rear flange 13, the inwall of noise reduction set 2 abuts the outer face of front flange 14, noise reduction set 2, front flange 14 and rear flange 13 crowd around formation cavity volume 6, described nail sleeve pipe 1 is provided with the circular bloop 12 that the uniform diameter of circumference is 1.5mm, described bloop 12 connects cavity volume 6 and through hole 11, the inner termination of bloop 12 is positioned at the front end face place of ammunition head 51, the external end head of bloop 12 is positioned at front flange 14 and the middle of rear flange 13, the angle of bloop 12 and horizontal direction is 38 degree, the quantity of described bloop 12 is three.Owing to the inner termination of bloop 12 to be located at the front end face place of ammunition head 51, the airflow produced in the firm instant of detonation of ammunition head 51 enters cavity volume 6 either directly through bloop 12, air-flow flows in bloop 12 and cavity volume 6 and reduces the noise of moment generation, the external end head of bloop 12 is positioned at front flange 14 and the middle of rear flange 13, make to distribute evenly during air current flow, the fluctuation produced is less, and overall erasure effect is very good.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should be encompassed within protection domain of the present utility model.
