Description
Technical field
The utility model relates to a kind of gas pin gun of adjustable nailing force.
Technical background
In using the process of gas pin gun, run into through regular meeting different wooden or use different size rifle nail to need the situation of different nailing forces so that the rifle nail enters the expection requirement that the depth of sheet material meets the user.
The nailing force of gas pin gun depends on the aeration quantity of air pressure and inner cylinders.Air pressure is provided by the air pump that ailing machine connected, though can regulate nailing force by changing air pump output pressure, this adjustment is rough, is difficult to grasp.And air pump and ailing machine often have specified air pressure, do not allow roomy air pressure adjustment.
Cylinder advance the stroke size that aeration quantity depends on balanced valve.And the stroke of the balanced valve of existing gas pin gun is fixed, can't adjustment stroke, thus the defective that causes nailing force to regulate; Use constant nailing force to increase air consumption, increased noise, reduced the nail rifle life-span, limited in its scope of application of occasion of the little nailing force of demand in addition.
Therefore, when the needs control nailing degree of depth, existing ailing machine can only rely on feel, the distance by changing muzzle and plate face and when pulling the trigger nailing gun-swinging speed realize.The effect of regulating depends on user's qualification, and for general user, this method is difficult for grasping.And because how many feels changes during each nailing, the nailing degree of depth is inhomogeneous.
Secondly, the stroke of the balanced valve of ailing machine all is arranged on optimum value in theory, is beneficial to bring into play EIAJ.But because foozle, every stroke the pairing balanced valve of EIAJ of ailing machine is different.Therefore, in fact the balanced valve stroke of most of ailing machines does not reach optimum value.
At last, the stroke of balanced valve fixedly is unfavorable for regulating the nailing frequency.Each nailing, balanced valve is walked a stroke back and forth.There are the relation of inverse correlation in the stroke of balanced valve and nailing frequency.Under specific occasions, need the suitable nailing frequency that meets user's custom.Obviously, the stroke of balanced valve fixedly is unfavorable for regulating the nailing frequency, and then the comfortableness of influence use.
The utility model content
For overcoming the above-mentioned shortcoming of existing ailing machine, the utility model provides a kind of adjustable ailing force, be convenient to the gas pin gun bringing into play EIAJ, be convenient to regulate the nailing frequency.
The gas pin gun of adjustable nailing force comprises rifle body, cylinder, goes up aluminium lid, is positioned at the balanced valve of aluminium lid inside;
It is characterized in that: the described afterbody of going up aluminium lid is provided with the governor motion of the position that can regulate described balanced valve;
Described governor motion comprises: the bolt and nut combination of adjustment valve position, the nut of described bolt and nut combination is fixed on described going up on the aluminium lid, the afterbody of the screw rod of described bolt and nut combination is provided with the knob that can drive the screw rod rotation, and the head of described screw rod is fixed with the liner of the stroke that is used to limit described balanced valve.
Further, described knob is connected with described screw rod by first feather key, and the surface of described screw rod is provided with the gathering sill that described first feather key of restriction moves on the axis of screw rod.
Further, described knob is connected with described nut by second feather key, and described nut is provided with the annular groove that only allows described knob rotation.
Further, described knob is provided with detent mechanism, and described detent mechanism comprises by back-moving spring and is fixed on the positioning bead on the knob and is positioned at the pit nut tail end, that can fix described positioning bead.
Technical conceive of the present utility model is: when needing to regulate nailing force, the rotation knob is under the effect of first feather key, screw rod rotate and forward (backward) move, drive liner forward (backward) move, thereby the stroke of adjustment valve reaches the purpose of regulating nailing force; When the balanced valve adjusting put in place, positioning bead snapped in the pit, limits knob position, it is no longer rotated.
Secondly, the balanced valve of ailing machine of the present utility model can Precision trimming, and the user can find every balanced valve stroke during the EIAJ of rifle by on probation, helps bringing into play the optimum performance of ailing machine.
Once more, utilize the stroke of balanced valve and the relation that there is inverse correlation in the nailing frequency,, can change the nailing frequency easily, find the user to feel optimal nailing frequency, improve the comfortableness of using by changing the position of balanced valve.
At last, when balanced valve was set to zero stroke, corresponding cylinder intake air quantity was zero, and ailing machine can't be pulled the trigger.Played the effect of safeties.The danger of can anti-errorly in advance hit, children playing false triggering.
The utility model has the advantages that: adjustable ailing force, reduce air consumption, reduce noise, improve the life-span, help bringing into play ailing machine EIAJ, be convenient to regulate nailing frequency, security good, enlarge the scope of application and advantage simple in structure, with low cost.

The specific embodiment
With reference to accompanying drawing, further specify the utility model:
The gas pin gun of adjustable nailing force comprises rifle body 1, cylinder 2, goes up aluminium lid 3, is positioned at the balanced valve 4 of aluminium lid 3 inside;
The described afterbody of going up aluminium lid 3 is provided with the governor motion of the position that can regulate described balanced valve 4;
Described governor motion comprises: the bolt and nut combination of adjustment valve 4 positions, the nut 51 of described bolt and nut combination is fixed on described going up on the aluminium lid 3, the afterbody of the screw rod 52 of described bolt and nut combination is provided with the knob 53 that can drive screw rod 52 rotations, the head of described screw rod 52 is fixed with the liner 54 of the stroke that is used to limit described balanced valve 4, and described liner 54 is the sealing cushion pad.
