Abstract

The utility model discloses a nail gun power regulating device and is positioned inside a nail gun which is composed of a gun body, a grasp, a press button, a nail box, a transmission tube which is positioned inside the gun body, an offsetting spring and a cylinder rod. The utility model comprises a cylindrical turn knob and a power regulating rod; one end-face of the cylindrical turn knob is provided with a plurality of small holes of different depths; the power regulating rod is arranged inside an axle hole which is pre-positioned in the wall of the transmission tube; through the rotary turn knob, the smaller axle-diameter head end of the power regulating rod is positioned into the different small holes in the end-face of the turn knob; the bigger axle-diameter end of the power regulating rod right bunts at flange of the cylinder rod in order to limit the distance between the cylinder rod and the bottom end of an explosion chamber. The rotary turn knob ensures that the head end of the power regulating rod is positioned into the small holes of different depths and can regulate distance between the cylinder rod and the bottom end of an explosion chamber. The further the distance, the bigger the space of the explosion chamber, and the smaller the ejector pin power formed during explosion; inversely, the ejector pin power is bigger. The utility model can regulate different ejector pin power for nail gun, in addition, it can not only avoid residual propulsion generating oscillation on other devices, but can reduce operation noise.

Description

Ail gun is transferred the prestige device

Technical field

The utility model relates to a kind of ail gun, relates in particular to a kind ofly to avoid remaining thrust that other mechanisms are produced beyond the vibrations, also can reduce the ail gun of operation noise and transfer the prestige device.

Background technology

Ail gun is widely used on the constructing operation relevant with cement wall nailing, its main motion characteristic is, utilize gunpowder outburst thrust to push ail gun internal piston bar, in order to the nail spare in the percussion front end nail casket, make the nail part hammer into correct position, utilize back-moving spring that piston rod is resetted again, to reach ejector pin action quickly and easily.

Existing ail gun, when above-mentioned percussion ejector pin moves, its ejector pin power generally all is to be decided at explosive force that explosion chamber produces by cartridge bag, in the design, though this outburst power is enough finished the required intensity of moment ejector pin via piston rod, but the thrust of gunpowder outburst is not absolute stability, or because of under the different situation of nail part specification, the thrust that the ejector pin action is remaining, can be sent in inner other mechanism of the body of a gun via back-moving spring, cause improper vibrations and noise, even destroy existing part function and structure.

The utility model content

In order to overcome the above-mentioned shortcoming that existing ail gun exists, the utility model provides a kind of assembly and ail gun accent prestige device simple in structure, the difference of its visual nail spare specification, regulating ail gun is different ejector pin powers, except that avoiding remaining thrust, also can reduce operation noise to other mechanisms' generation vibrations.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of ail gun is transferred the prestige device, be arranged on by the body of a gun, handle, signature button, follow closely casket, be positioned at the ail gun inside that transmitting tube, a back-moving spring and a piston rod of body of a gun inside are formed, it is characterized in that, comprise: a cylindric turn-button, an end face are provided with the aperture of a plurality of different depths along its circumference; One transfers the prestige bar, be to be located in the default axis hole of transmitting tube tube wall, transfer the less head end of the prestige bar diameter of axle, be placed in the different aperture of turn-button end face through rotating this turn-button, transfer the bigger end of the prestige bar diameter of axle, just can only be butted on the flange of piston rod, the distance of piston rod and explosion chamber bottom is restricted; Rotate turn-button, make and transfer the prestige rod head end to insert in the aperture of different depth, the adjusting piston bar is to the distance of explosion chamber bottom, and distance is far away more, and the explosion chamber space is big more, and the ejector pin power that forms during outburst is just more little, otherwise the ejector pin power is just big more.

The beneficial effects of the utility model are, the difference of its visual nail spare specification, regulating ail gun is different ejector pin powers, remove can avoid remaining thrust to other mechanisms produce shake, also can reduce operation noise.

The specific embodiment

See also Fig. 1, Fig. 2, the utility model ail gun is transferred the prestige device, is arranged on the ail gun, and this ail gun comprises the body of a gun 10, handle 11, signature button 12, nail casket 13, is positioned at transmitting tube 14, a back-moving spring 15 and a piston rod 16 of the body of a gun 10 inside.

As shown in Figure 3, transfer the prestige device to comprise that cylindric turn-button 20, one end faces are provided with the aperture 21 of a plurality of different depths along its circumference; One accent prestige bar 22 is to be located in the default axis hole 18 of transmitting tube 14 tube walls, this transfers the less head end 23 of prestige bar 22 diameters of axle, can be through rotating this turn-button 20, and be placed in the different aperture of turn-button end face 21, transfer the bigger end 24 of prestige bar 22 diameters of axle, just can only be butted on the flange 17 of piston rod 16, the accent prestige device after combination, its structure is as shown in Figure 2.

As shown in Figure 2, turn-button 20 is sides that are hubbed on the body of a gun 10, just is positioned at the side of transmitting tube 14 ends; This accent prestige bar 22 is located in the axis hole 18 on transmitting tube 14 tube walls, transfers the flange 17 of the bigger end 24 contact piston bars 16 of prestige bar 22 diameters of axle to form and ends the state of supporting, and in view of the above, and the piston rod 16 and the distance of explosion chamber 19 bottoms is restricted.

Transfer the length that protrudes out of prestige bar 22, determined the space size of explosion chamber 19; When rotating turn-button 20, order transfers prestige bar 22 head ends 23 to insert in the aperture 21 of different depth, with regard to the distance of adjusting piston bar 16 to explosion chamber 19 bottoms, distance is far away more, and explosion chamber 19 spaces are big more, the ejector pin power that forms during outburst is just more little, otherwise if regulating piston bar 16 is near more to the distance of explosion chamber 19 bottoms, explosion chamber 19 spaces diminish, the ejector pin power that forms during outburst is just big more, reaches the aforementioned purpose of regulating ail gun ejector pin power.

When the turn-button 20 of transferring the prestige device is set on the same gear, piston rod 16 end faces are constant to the distance of transmitting tube explosion chamber 19 bottoms, and stable ejector pin power can be provided.

As shown in Figure 1, the turn-button 20 of above-mentioned accent prestige device is included in the outer surface of turn-button 20, can indicate different shelves item numbers according to the aperture 21 of different depth, so that regulate operation.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
