Description

A kind of ail shooter

Technical field

The utility model relates to a kind of ail shooter that is used for the fastening equipment industry of nailing, and it is used for members such as concrete, iron and steel, brick, rock, finishes various fixations.

Background technology

At present, universal low speed piston type ail shooter mainly is made up of parts such as nail pipe, piston cylinder, piston rod, cartridge chamber body, outer sleeve, trigger, handles.Earlier nailing is packed into during use in the nail pore, in the cartridge chamber body of again nail shooting pill being packed into, ail shooter nail pipe vertically is pressed on the working reference plane, pushes handle with hand-power, the nail pipe is retreated be compressed to extreme position, and the cocking percussion is injected nailing in matrix.Shell case is withdrawed from pulling out the nail pipe in the percussion back when piston rod is resetted.Every shooting once all needs to be undertaken by above operating sequence.

But, because the ail shooter (307 types, 301 types, 603 types) of present three kinds all is to use joining bullet, join nail and finish separately fire mission separately, and be the single-shot ammunition feed, as using multiple nailing when the construction operation, just must get and use three kinds of ail shooters repeatedly, cause trouble for manufacturing and construction, and improved construction cost.

The utility model content

The utility model provides a kind of modified ail shooter, and this ail shooter becomes present ammunition feed continuously automatically with former single-shot ammunition feed, adopts joining bullet and just finishing each serial nailing and pull the trigger task of a series simultaneously.

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

A kind of ail shooter, comprise striker post, firing pin, handle, trigger, nail pipe, piston cylinder, piston rod, piston, outer sleeve, cartridge chamber body, handle comprises cylindrical drum and handle, the internal diameter of handle cylindrical drum and the external diameter of outer sleeve are slidingly matched, front end at striker post is provided with groove, the rear end of outer sleeve has window, and offers window on the opposite position of the cylindrical drum of handle and outer sleeve, is equipped with the magazine that band is dialled the bullet device between the groove of cartridge chamber body and striker post front end.

Above-mentioned ail shooter is connected with the front end of piston cylinder at the nail pipe, is provided with to be followed closely the spacing brake hoop of pipe rear end macropore between nail pipe and piston cylinder.

The beneficial effects of the utility model are, can substitute existing three kinds of ail shooters, reached multi-use effect, and running fire automatically, simple in structure, reduce and saved production cost, improved construction production efficiency.

The specific embodiment

The utility model improves on the basis of original NS307A type ail shooter, cartridge chamber body 7 internal diameters and gradient thereof is increased, simultaneously with its afterbody lengthening, to be suitable for S1 (6.8 * 11) model nail shooting pill; With striker post 8 front ends lengthening and formation groove, increase and dial the bullet device, simultaneously outer sleeve and handle relevant position are windowed, and,, be convenient to send automatically bullet to be suitable for S1 model nail shooting pill magazine with original fluting position sealing on the outer sleeve.In order to use opposite sex nail and M nail, increase a spare nail pipe (bore difference) in addition.

Below in conjunction with drawings and Examples the utility model is further specified.

Ail shooter shown in Figure 1 is made up of firing lock and trigger mechanism.Its firing lock comprises striker post 8, insurance spring, insurance sear, firing pin marshall springs 9, firing pin 14, striker spring 15, and parts such as handle, trigger 12 are formed.Handle is divided into

cylindrical drum

10 and 11 two parts of handle, and striker post 8 is processed by steel part, is installed in the cylindrical drum 10 of handle.The front end of striker post 8 is provided with groove, is used for inserting magazine (not drawing among the figure), and is connected fastening with it.What be right after groove is axial striker post 8 holes, and firing pin 14 passes striker post 8 holes can collide nail shooting pill (not drawing among the figure) in the magazine, is provided with hole and groove under striker post 8 holes, and the hole is used for adorning insurance spring, and groove is used for dress insurance sear.When striker post 8 compressions retreated, the safety feature of firing pin 14 strengthened with the resistance increase of sear to firing pin 14.Firing pin marshall springs 9 one ends are against striker post 8 afterbodys, and the other end is fixed on the inwall of outer sleeve 1 rear end.

Firing pin 14 is divided into syringe needle, shank, is arranged on baffle ring 16 several sections of shank rear portion periphery, and shank is two sections cylinders, and the cylindrical diameter of back segment is greater than the nose circle cylinder.Striker spring 15 1 ends are against baffle ring 16, and the other end is against on the handle inwall.Being positioned at firing pin 14 following triggers 12 is a bulk, pawl, pin-and-hole and trigger 12 springs 13 are arranged above the trigger 12, being passed pin-and-hole by pin is hinged on the handle, when the pawl on the trigger 12 is connected with sear, cocking 12 can be removed the constraint of sear to firing pin 14, by trigger 12 springs 13 trigger 12 is resetted.

Trigger mechanism is made of nail pipe 2, piston cylinder 6, piston rod 4, brake hoop 3, outer sleeve 1, cartridge chamber body 7 etc.By the hold-down mechanism that constitutes by spacer pin 19, stage clip 17, stage clip pin 18, friction top 20, nail pipe 2 can be compressed, it is being on the same axis with piston cylinder 6 and outer sleeve 1.The rear end of nail pipe 2 is threaded with the front end of piston cylinder 6, offer than the big slightly macropore of nail pipe diameter in nail pipe 2 rear ends, at the macropore place brake hoop 3 is housed, the rear end of piston cylinder 6 is provided with screw thread, can be connected with cartridge chamber body 7 front end screw threads, piston 5 is enclosed within on the piston rod 4.The outside of piston cylinder 6 is provided with outer sleeve 1, and outer sleeve 1 is slidingly matched with the internal diameter of the cylindrical drum 10 of handle.Cartridge chamber body 7 is between piston cylinder 6 and striker post 8.Be equipped with window (not drawing among the figure) on the cylindrical drum 10 of handle and outer sleeve 1, pushing 1, two window of outer sleeve backward can overlaid, and the nail shooting pill magazine can be inserted in striker post 8 grooves by cylindrical drum 10, outer sleeve 1 place of windowing of handle.

During use, cylindrical drum 10, outer sleeve 1 place of windowing by handle inserts in striker post 8 grooves with S1 model nail shooting pill magazine, nailing is packed in nail pipe 2 holes, ail shooter nail pipe 2 vertically is pressed on the working reference plane, pushes handle with hand-power, nail pipe 2 is retreated be compressed to extreme position, cocking 12 percussions, firing pin 14 is disengaged constraint percussion nail shooting pill, and it is pressed in the cartridge chamber body 7, further promotes piston rod 4 reaches and nailing is hammered into matrix.The percussion back resets piston rod 4 with pulling out nail pipe 2, dials the bullet device simultaneously and automatically magazine is moved to next nail shooting pill position, shoots next time.Use opposite sex nail and M nail as need, only need to change spare nail pipe 2 and get final product, method of operating is identical.So just, reached former single-shot ammunition feed has been become automatically continuously ammunition feed, adopted joining bullet and just finishing the purpose that each serial nailing is pulled the trigger task of a series simultaneously.
