Abstract

The utility model provides a two-function pneumatic nail gun for cement and wood, which includes a shell, an air cylinder, a cylinder cover, a balance valve, a gun cover, a gun head, a firing pin, a nail box, a trigger piece, an air inlet mouth, a buffering pad between the air cylinder and the shell and an O-shaped sealing ring between the shell and the cylinder cover. The utility model is characterized in that a reset spring is arranged between the balance valve and the cylinder cover; a triggering rod is arranged on the gun head to form a safety device with the trigger piece; and a nail guide groove consisting of the gun head and the nail box is divided into different intervals by bars. When compressed air is led in the gun through the air inlet mouth, the trigger piece is pulled, and the triggering rod on the gun head is pressed on a nailing object, meanwhile, the pneumatic force at the back of the balance valve is shut off, and the balance valve is separated from the air cylinder. The compressed air enters the air cylinder rapidly to push the firing pin to strike the tail of the nail in the nail box, so as to eject the nail and nail the object. The nail can be shot only when the triggering rod is pressed on the object, thus the utility model has good safety effect. The nail guide groove is divided into intervals by bars, in order to control different nails and make the pneumatic nail gun have two functions.

Description

Pneumatic nail gun with cement timber double-purpose functional

Affiliated technical field

The utility model relates to a kind of pneumatic tool, refers in particular to a kind of pneumatic nail gun with cement timber double-purpose functional.

Background technology

Existing pneumatic nail gun is made up of parts such as housing, cylinder, cylinder head, cylinder jacket, sealing ring, cushion pad, striker, nail casket, trigger piece, valves, when compressed air imports the rifle body from valve, pull trigger piece, the pressure at balanced valve rear portion is less than the pressure of balanced valve front portion at this moment, balanced valve is opened, and compressed air enters rapidly in the cylinder jacket, and the row who promotes in the piston drive striker bump nail casket follows closely afterbody, the row's of making nail penetrates, to reach the purpose that connects object with row's nail.But existing pneumatic nail gun function singleness, what be used for cement products is a kind of pneumatic nail gun, what be used for timber-work is again another kind of pneumatic nail gun.

Summary of the invention

Task of the present utility model is to provide a kind of pneumatic nail gun with cement timber double-purpose functional, and its rifle is dual-purpose, and functional mapping is convenient again, and has insurance function.

For finishing above-mentioned task, the solution that the utility model is taked is: a kind of pneumatic nail gun with cement timber double-purpose functional, include housing, cylinder, cylinder head, balanced valve, rifle lid, rifle head, striker, nail casket, trigger piece, suction nozzle, one cushion pad is arranged between cylinder and the housing, an O RunddichtringO is arranged between housing and the cylinder head, it is characterized in that a back-moving spring is arranged between balanced valve and cylinder head, there are frizzen and trigger piece to constitute safeties on the rifle head, have muscle to be divided into different intervals on the guide nail slot of rifle head and nail casket formation.

When compressed air imports the rifle body from suction nozzle, pull trigger piece and the frizzen on the rifle head is pressed on the stitching thing, this moment, the strength at balanced valve rear portion was closed, balanced valve and cylinder leave, compressed air enters in the cylinder rapidly, the row who promotes in the striker bump nail casket follows closely afterbody, and the row's of making nail penetrates, to reach the purpose that connects object with row's nail.Because just possible nailing had insurance function after frizzen was pressed on the stitching thing, make product comparatively safe reliable when operation.There is muscle to be divided into different intervals on rifle head and the guide nail slot that the nail casket constitutes, be used to control row's nail of different model, specification, use straight nail to be used for the timber-work stitching, use the cement steel nail to be used for the cement products stitching, one rifle is dual-purpose, the row that functional mapping only need be changed different model, specification has followed closely just, and it is quite convenient to use.
