Employing the invention has the advantages that:
One, in the present invention, because the pressure differential that make use of between each cavity that balanced valve, rifle body and piston component form realizes the shooting of nail, compressed air not only can be adopted as the power source of ail gun, also make that the issuing velocity of nail is faster and injection dynamics is also larger, its injection dynamics can reach 150J-190J, instantaneously nail can not only be driven into wooden matrix, can also instantaneously nail be directly driven in the hard substrate as iron and steel, concrete, brick setting or rock type, there is high efficient and reliable, low-carbon environment-friendly and advantage applied widely, balanced valve makes the loss of compressed-air actuated admission pressure little simultaneously, and row's back of the body air pressure is little, because the power of ail gun is larger, in order to ensure the safe handling of ail shooter, invention increases unique safeties, the trigger when connecting compressed air and load nail can be made to be in force-free state, namely cocking cannot be shot, only have and just can carry out nailing after pressing down rifle head drive safeties, further increase the security of ail gun, can reduce because accidentally using the probability causing security incident, the prior art being representative with China Patent No. " 200320118911.1 " and " 00222911.0 " is compared, the present invention is owing to make use of balanced valve, pressure differential between each cavity that rifle body and piston component are formed realizes nailing, make the injection dynamics of nail larger, shooting rate of precision is higher, and use compressed air as power source, not only economize energy, be conducive to environmental protection, also significantly reduce production cost, and the setting of safeties makes ail gun have higher security.
Two, in the present invention, Insurance Block can prevent insurance pressing plate sideslip when shooting, and the insurance pressing plate after spring can make releasing trigger automatically resets rapidly, has the advantage that structure is simple, nailing efficiency is high; Only have when pressing down rifle head, when one end of insurance pressing plate is moved to safeguard and supports safeguard, trigger with the contact point insuring pressing plate and safeguard for basic point is stressed, can could prevents maloperation and cause security incident simultaneously.
Three, in the present invention; coordinated the pressure that can change control chamber flexibly and easily with valve by trigger; thus realize the high efficiency shooting of nail; and the advantage that handle has handled easily is set in rifle body bottom; what the snap joint on handle made compressed air inlet duct is connected more firm with inlet channel, and handle can shield to inlet channel simultaneously.
Four, in the present invention, described cylinder block outer surface is provided with retainer ring, cavity between cylinder block and rifle body is divided into return-air cabin and air storage chamber by described retainer ring, described cylinder block arranges some openings, described some openings are separately positioned in the cylinder block in the middle part of cylinder block end and corresponding return-air cabin, described return-air cabin is communicated with cylinder block by opening, this arranges the compact conformation making ail gun, the volume of whole rifle body is less, air pressure after simultaneously making releasing trigger in return-air cabin is greater than the air pressure in cylinder block, rapidly piston and piston rod can be automatically reset, not only economize energy, fire efficiency can also be improved.
Five, the cavity that in the present invention, described control chamber is cylinder head, the bonnet of balanced valve and rifle body is combined to form, it is simple that this arranges the formation making control chamber, is easy to realize; And before cocking, the balanced valve after elastic device can make releasing trigger automatically reset rapidly and with cylinder block compact siro spinning technology so that shooting next time.
Six, in the present invention, described rifle body bonnet arranges sealing gasket, can block exhaust passage fast and effectively by sealing gasket during cocking to communicate with air, prevent air from entering in cylinder block, the compressed air in guarantee air storage chamber can promote piston instantaneously and nail hits by piston rod.
Seven, in the present invention, beam can not only reduce the impulsive force of ail gun when nail hitting, can also improve the accuracy rate of nail shooting.
Eight, in the present invention, described rifle head comprises barrel block and gun barrel, the side of described barrel block is fixedly connected with rifle body, opposite side is connected with gun barrel sleeve, described gun barrel is movably set in gun barrel sleeve, and this structure can pass through gun barrel sleeve and the gun barrel of changing different size, so that the nail of shooting different size, be conducive to the utilization rate improving ail gun, the installing/dismounting of rifle head is more convenient simultaneously.
Nine, in the present invention, described limiting section can make gun barrel locate in gun barrel sleeve, improves installation precision and the shooting accuracy of gun barrel; Described pressing plate coordinates with the body of a gun upper limit platform moving range limiting gun barrel, prevents gun barrel from dropping from gun barrel sleeve under the impact of piston rod; Described insurance pressing plate is flexibly connected with gun barrel by through hole and safety groove, and safeties are connected with trigger, improves the security of ail gun further; Described limited post is connected for limiting the displacement insuring pressing plate with insurance pressing plate, avoids the displacement because insuring pressing plate too much safeguard to be damaged.
Ten, in the present invention, nail kit is set and not only makes binding become more simple and fast, more nail can also be loaded in nail kit, realize high-efficiency and continuous shooting; Nail in nail kit can be sent in gun barrel by nails introducer automatically, makes nail in gun barrel can sequential filming, improves fire efficiency; If the nail simultaneously in nail kit seldom or when not having, prevention gun barrel is depressed by push rod and mating recesses, represent and now need to add nail, prevent blank firing.
11, in the present invention, retaining screw device can either prevent nail from skidding off from nail kit, is also convenient to from nail kit, take out the nail do not used.
12, in the present invention; when the nail needing shooting shorter than design specification; baffle can play position-limiting action to short specification nail; prevent from damaging nail kit because nail is crooked during shooting; long size nail can be stoped to be loaded into shooting simultaneously, prevent the nail in use using length inconsistent.
13, in the present invention, described nail kit is fixedly connected with handle by clamping plate, and this structure makes the stability of nail kit better.
14, in the present invention, described rifle head comprises barrel block and gun barrel, the side of described barrel block is fixedly connected with rifle body, opposite side is slidably connected by jump ring and gun barrel, described insurance pressing plate is between barrel block and gun barrel, this structure is mainly suitable for the shooting of bar for line, and install the nail that different rifle head just can shoot different size, the utilization rate of ail gun is high.
15, in the present invention, because the injection dynamics of ail gun can reach 150J-190J, instantaneously nail can not only be driven into wooden matrix, can also be directly driven into by nail instantaneously in the hard substrate as iron and steel, concrete, brick setting or rock type, its scope of application is wide; Described ail gun can shoot the nail and bar for line that length is 19-62mm simultaneously, and on same rifle body, the rifle head installing different size just can shoot nail and the bar for line of different size, and the utilization rate of ail gun is high.
