Description

Integrated silencing, deslagging and heat dissipating structure of nail shooter and nail pipe

Technical Field

The utility model relates to a ail shooter field especially relates to an integral type amortization of ail shooter is arranged sediment heat radiation structure and is followed closely a tub.

Background

When the nail shooter is used, the integrated nail shooting bomb explodes in the nail pipe, gas generated by explosion pushes the shooting nail into the base body, the nail shooting process is completed, but the explosion can generate huge noise at the same time, and sound wave impact is formed on site construction personnel. In order to overcome noise generated by explosion, a silencing hole is usually processed on the nail tube, a silencing cover is sleeved outside the nail tube, a closed silencing cavity is formed between the nail tube and the silencing cover, and the noise enters the silencing cavity through the silencing hole to be weakened, so that the noise reduction effect can be achieved. But the residue piece after the nail shooting bullet explosion also can follow the amortization chamber of amortization hole entering simultaneously, and the residue can be silted up in the amortization chamber, and the time of having of a specified duration still can be caked, and amortization chamber volume is less, needs regularly to dismantle the amortization cover in time to clear up the residue, and it is very inconvenient to use, still can influence work efficiency. In addition, still can produce a large amount of heats when the ail shooter explodes, and partial heat also can get into the amortization chamber through the amortization hole, and the heat can not obtain effectual scattering and disappearing, consequently along with the increase of shooting number of times, the temperature of amortization cover can rise gradually, leads to inconvenient shell action of moving back, still can bring serious potential safety hazard for constructor.
