Description

Walk away safety safeties pneumatic nail gun

The utility model relates to a kind of pneumatic tool, particularly a kind of pneumatic nail gun with walk away safety safeties.

Existing pneumatic nail gun generally comprises by parts such as rifle housing, cylinder head, cylinder jacket, sealing ring, cushion pad, striker, nailing mouth, nail casket, trigger piece, air inlet pipe to be formed, when Compressed Gas imports the rifle body, pulls trigger piece from air inlet pipe, the pressure at balanced valve rear portion is less than the pressure of balanced valve front portion at this moment, balanced valve is opened, compressed air enters in the cylinder jacket rapidly, promote piston and drive the interior clasp nail afterbody of push rod (striker) bump nail casket, clasp nail is penetrated, to reach the purpose that connects object with clasp nail.But existing pneumatic nail gun exists the design of part more complicated, and manufacturing procedure is many, thereby the cost of manufacture height,, and when this pneumatic nail gun uses when nail is made firmly working substance easy bail, be subjected to structural limitations, the interlock safety locking motion can not be installed, have unsafe factor.

The purpose of this utility model provides a kind of simple in structure, easy to use, comparatively safe, and the pneumatic nail gun with walk away safety safeties that can reduce cost.

The utility model is to realize by following scheme: as shown in Figure 1, by the rifle housing, cylinder head, cylinder jacket, sealing ring, cushion pad, striker, the nailing mouth, the nail casket, trigger piece, the walk away safety safeties pneumatic nail gun that parts such as air inlet pipe are formed, the interior die cavity 19 (Fig. 2) that it is characterized in that the pneumatic nail gun housing adopts the rheo-die-casting moulding, need not carry out a series of parts that machining just can be assembled die cavity inside, between cylinder jacket (Fig. 3) outside in the die cavity and the housing cushion pad 8 is arranged, to simplify the manufacturing procedure of cylinder jacket, save material, in order to improve sealing effectiveness and to be convenient to assembling and replacing, " O " RunddichtringO 5 is arranged between housing 1 and the cylinder head 2, for the work that makes balanced valve more reliable and more stable, a main spring 3 is housed between balanced valve 4 and cylinder head 2, connecting on the bearing pin 11 that starts trigger piece 12, by a simple and easy security danger device of being formed by spring 10 and insurance trigger piece 13.The nailing mouth 9 of the pegging gun of this pneumatic nail gun series (beat " one " font nail), its inside are used for " upper lip " 16 that " mountain " font guide nail slot (Fig. 5) that guide pin uses is mounted in the nailing mouth, to eliminate " bail " phenomenon.

The utility model compared with prior art, owing to simplified the structure of major part, reduced machining, the percentage of A-class goods and the service behaviour of major part have been improved, assembling and convenient disassembly, greatly reduce manufacturing cost, and the walk away safety safeties are installed, make product comparatively safe reliable when operation.

Below in conjunction with accompanying drawing enforcement of the present utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;
