The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed description:

Referring to Fig. 1, Fig. 2, the embodiment of a kind of high-pressure pneumatic nailing machine that provides at the utility model, the cylinder that comprise a rifle body, be installed in the interior striker of described rifle body, the described striker of driving moves, the exhaust seat that is installed in the gases at high pressure balanced valve in the described rifle body and discharges for described cylinder inner high voltage gas, said structure all belongs to the prior art of comparative maturity, and the concrete structure and the course of work repeat no more herein.The difference of the utility model and prior art is, the front end of described exhaust seat is formed with exhaust outlet 4, described exhaust seat internal shaping has exhaust passage 3, described exhaust passage 3 communicates with described exhaust outlet 4, gases at high pressure in the described cylinder are discharged from the exhaust outlet that is positioned at described exhaust seat front end after described exhaust passage turns to.Exhaust passage 3 of the present utility model can turn to gases at high pressure, allows gases at high pressure discharge forward, thereby avoids gases at high pressure to discharge backward from afterbody, directly towards the user, the user is damaged, and eliminates the potential safety hazard that exists.

Referring to Fig. 1, Fig. 3, Fig. 6, in the foregoing description that the utility model provides, described exhaust seat comprises front exhaust lid 1 and final vacuum lid 2, and described final vacuum lid 2 is installed in the rear end of front exhaust lid 1.Described front exhaust lid 1 comprises front exhaust lid inwall 11 and front exhaust cover outer wall 12, is formed with exhaust cavity between described front exhaust lid inwall 11 and the front exhaust cover outer wall 12, and the front end of described exhaust cavity forms described exhaust outlet 4.The exhaust cavity that said structure constitutes is bigger, can discharge more gases at high pressure in moment, thereby reduces the noise of gases at high pressure hand that produces when discharging.The center, rear end of described front exhaust lid 1 evenly is provided with a plurality of central row pores 13, the rear end peripheral position of described front exhaust lid 1 is provided with a plurality of peripheral exhaust ports 14, described central row pore 13 communicates with described cylinder, described peripheral exhaust port 14 communicates with described exhaust cavity, described central row pore 13 communicates with described peripheral exhaust port 14, can make the exhaust passage 3 of discharging after the described cylinder inner high voltage gas turns thereby form.Said structure has constituted a complete exhaust passage 3, and cylinder inner high voltage gas is discharged from center steam vent 13, turns to the back to enter the exhaust cavity from peripheral exhaust port 14, discharges from exhaust outlet 4 again.Thereby realize gases at high pressure are discharged forward, avoid directly arranging to the user.Said structure is fairly simple, and is beneficial to the discharging of gases at high pressure.

Referring to Fig. 2, in the foregoing description that the utility model provides, form a cavity between described final vacuum lid 2 and the described front exhaust lid 1, described central row pore 13 communicates with described cavity respectively with described peripheral exhaust port 14.The gases at high pressure of discharging from cylinder enter in the described cavity, discharge through described peripheral exhaust port 14 from described cavity again.Described cavity plays the effect of buffering to described gases at high pressure, reduces the noise that high pressure gas produces.

Referring to Fig. 2, in the foregoing description that the utility model provides, described exhaust cap 1 and the final vacuum lid 2 of the going forward position that combines is provided with gasket seal 16.The effect that described gasket seal 16 plays sealing is set, prevents gas leakage.

Referring to Fig. 5, in the foregoing description that the utility model provides, described central row pore 13 is a circular port, and described peripheral exhaust port 14 is a mounting hole.Described peripheral exhaust port 14 is set to mounting hole can increases the exhaust passage as much as possible, improve capacity, reduce the noise of hand that exhaust is produced.

Referring to Fig. 4, in the foregoing description that the utility model provides, the wall thickness of described front exhaust lid inwall 11 is greater than the wall thickness of front exhaust cover outer wall 12.Said structure can effectively improve integral intensity.
