Abstract

The utility model relates to a hand air hammer, which consists of sunken type bolts, an upper cover, an upper binding block, a sealing ring, a gas check ring, a sliding sleeve, a cylinder, a lower binding block, a shell, a hammer rod, a buffering cushion, an outer sleeve, a spring and a guide pipe. The rear end of the shell is connected with the upper cover, and the upper cover and the shell are screwed through sunken type bolts in four corners. The upper part of the shell is provided with high-voltage gas port for connecting the air supply which enters into the cylinder through an air flue. Under the driving of the high-voltage air, the binding blocks move to the bottom of the cylinder, and the nails are put into the guide pipe; the hammer rod move upwards by pressing the hand air hammer downwards. As the high-voltage air is pressed, the hammer rod is driven to move downwards so as to hammer repeatedly. When in use, the nails are hammered, which is stable and reliable, and can reduce labor intensity and ensures the construction quality.

Description

A kind of Portable air hammer

The utility model relates to pneumatic tool, relates in particular to a kind of Portable air hammer.

The beche of prior art is the pneumatic tool of big hitting power, and profile is comparatively heavy, and the scope of application is little; And be used for the hammer that nailing is used on plank or wall, and being general manual hammer, hitting dynamics is less, especially when squeezing into nail on the cement wall surface, because nail to be squeezed into is very difficult stable, so it is bigger to squeeze into the difficulty of nail, and very easily hurt sb.'s feelings poor stability.

The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of Portable air hammer is provided, with the power of gases at high pressure as hammering, can replace manual hammer, small and exquisite flexible, and hitting dynamics is bigger, for the strike of the head of a nail, reliable and stable, can reduce labour intensity, when especially (on end face) squeezes into the operation of nail on the bigger scope of operation of difficulty, degree of accuracy height, dangerous little, can guarantee construction quality well.

A kind of Portable air hammer described in the utility model, including invaginating screw, loam cake, last combined block, sealing ring, obturator ring, sliding sleeve, hammer cylinder, following combined block, housing, hammer stem, cushion pad, outer tube, spring and guide pipe forms, described housing is the body supports part of Portable air hammer described in the utility model, the rear end of housing is connected to loam cake, the type of attachment of loam cake and housing adopts and tightens loam cake and housing fixing with four invaginating screws in four angles.For being fit to the gripping in the hand, the top of housing cooperates loam cake, is designed to be similar to substantially the form of olive.The olivary end on housing top generally is at little head end, is provided for inserting the high pressure gas port of high-pressure air pipe.Insert high-pressure air source from the high pressure gas port, make pressure-air enter the hammer cylinder by the air flue that is arranged on high pressure gas port back, the form that is provided with of air flue and the beche of prior art are basic identical.Pressure-air promotes down, and combined block moves downward to the bottom of hammer cylinder, nail to be squeezed into is put into guide pipe earlier, perpendicular to predetermined nailing position, with pneumatic hammer in the downward pressing device of hand, hammer stem will move upward under the effect of reaction force, owing to pressure-air pressurized this moment, can promote hammer stem again moves downward, hammer stem is upspring when hammering into shape to the head of a nail, and does the action of hammering repeatedly, until the position of nail being squeezed into requirement.Center at housing described in the utility model is provided with hammer stem.Hammer stem is the circular bar shape structure, and the front end of hammer stem is to hit end, and the rear end of hammer stem is provided with hammer cylinder and sliding sleeve.The version of said hammer cylinder, basic identical with the version of the air tool hammer cylinder of prior art, the hammer cylinder moves in sliding sleeve.On each binding site in the hammer cylinder, be provided with sealing ring, according to the concrete condition of each binding site, the model of sealing ring is different.The form of sealing ring is set on each binding site here, also is the structure with reference to existing large-scale pneumatic hammer, carries out that technology transplant designs again.In air flue and the position that the hammer cylinder is connected, be provided with obturator ring.In the rear end of hammer stem, below the loam cake, match with loam cake, be provided with combined block, be provided with down combined block with last combined block corresponding matching.For guaranteeing the stability of hammer stem when implementing to hit, the postmedian position at hammer stem is provided with cushion pad, and is provided with guide pipe at the strike end of hammer stem.Guide pipe is arranged on outside the hammer stem, in the outer tube.In outer tube, also be provided with the spring that guide pipe is protracted.Outer tube adopts the external spiral structure, is arranged in the inside spin of housing lower end, at first installs guide pipe and spring, is inserted in the hammering end of hammer stem again, is tightened in interior the getting final product of inside spin of housing lower end.Guide pipe protracts under the effect of spring, and the effect that guide pipe is protracted is, can stably the nail for the treatment of hammering be controlled in the guide pipe, exactly nail is implemented hammering.

Use a kind of Portable air hammer described in the utility model, because the effect of guide pipe, can hand Portable air hammer, nail to be squeezed into is placed in the guide pipe, nail is implemented hammering, especially can be used on cement wall surface, squeezing into steel nail, reliable and stable, can reduce the intensity of work than the highland, guarantee construction quality, increase the security of operation.Portable air hammer described in the utility model is a revolution of the nailing of prior art being used fullering tool, can be widely used in indoor and outdoor decorations operation.
