Description

Pneumatic nail gun

The utility model relates to a kind of pneumatic tool, refers in particular to a kind of pneumatic nail gun.

So-called pneumatic nail gun utilizes source of the gas to carry out the rifle formula nailing instrument of nailing exactly.Existing pneumatic nail gun use straight nail as F type pneumatic nail gun or use that T shape head directly follows closely be T type pneumatic nail gun (all being commonly called as straight nail rifle), use being of H staple J type pneumatic nail gun (being commonly called as the flat nail rifle), that uses the straight staple of no ailhead is P type pneumatic nail gun (being commonly called as pegging gun), that uses that square ailhead directly follows closely is ST type pneumatic nail gun (being commonly called as steel nail gun), their structure is much the same, comprise housing, cylinder and cylinder head, piston, cartridge clip, the rifle head, striker, balanced valve, trigger piece, valve rod, valve etc., operation principle is also identical: when Compressed Gas imports the rifle body from valve, pull trigger piece, the pressure at balanced valve rear portion is less than the pressure of balanced valve front portion at this moment, balanced valve is opened, Compressed Gas enters in the cylinder rapidly, promote the afterbody that piston drives the nail in the striker bump cartridge clip, nail is penetrated, and difference mainly is that the cartridge clip of binding is different with the striker shape.But, at present the existing same defect of these pneumatic nail guns mainly contains three aspects: the one, and dangerous, as long as in the cartridge clip nail is housed, any direction is pulled trigger piece will nailing, therefore, manufacturer of every family is marked with " not aiming at the people " or printed words such as " please don't aim at the people " on packing (box); The 2nd, can only single-shot, promptly pull trigger piece and once penetrate one piece of nail, inefficiency; The 3rd, steam vent is fixed, if operate the eyes of just hurting sb.'s feelings easily in discharge directions.

In order to overcome the above-mentioned defective that existing technology exists, task of the present utility model is to provide a kind of pneumatic nail gun, and it has security insurance and running fire function, and the single-shot running fire is selected arbitrarily, can soon can be slow during operation, and operation all is not easy the eyes of hurting sb.'s feelings in any direction.

For finishing above-mentioned task, the solution that the utility model is taked is: a kind of pneumatic nail gun, comprise housing, cylinder and cylinder head, piston, cartridge clip, rifle head, striker, balanced valve, trigger piece, valve rod, valve etc., its feature in, the security insurance trigger head is housed on the rifle head replenishes and start trigger piece and finish the work.

Described trigger piece and single running fire transaxle Colaesce mutually change described valve rod turnover position.

On the described cylinder head exhaust cap is housed, described exhaust cap is rotatable.

The security insurance trigger head mainly changes the position of trigger piece Push And Release, in the process that trigger piece is being opened, there is not one-time-reach-place, pulling trigger piece when having only the security insurance trigger head to run into working substance just can put in place, promptly replenish the work of finishing one-time-reach-place of the prior art, reached the effect of security insurance with the security insurance trigger head.Trigger piece and single running fire transaxle Colaesce mutually change valve rod turnover position, and when single running fire transaxle is in single-engine run, valve rod turnover position is same as the prior art; When single running fire transaxle is in the running fire state, valve rod turnover position difference, source of the gas feeding flow draws into automatic vent, produces running fire.Being equipped with on the cylinder head to change exhaust cap, and can change exhaust cap and can optionally change direction and promptly changed discharge directions, so the eyes of can not hurting sb.'s feelings during exhaust.

Below in conjunction with embodiment and accompanying drawing thereof the beneficial effect of the utility model and generation thereof is remake description.

Fig. 1 is the structural representation of present embodiment.

Fig. 2 is the position view that present embodiment list running fire transaxle is in the running fire state.

Fig. 3 is the position view that present embodiment list running fire transaxle is in single-engine run.

Among the figure: 1, housing, 2, cylinder head, 3, cylinder, 4, spring, 5, the O RunddichtringO, 6, the O RunddichtringO, 7, the O RunddichtringO, 8, sealing gasket, 9, collar, 10, striker, 11, balanced valve, 12, cushion pad, 13, the O RunddichtringO, 14, exhaust cap, 15, spring, 16, the O RunddichtringO, 17, valve seat, 18, valve rod, 19, guide, 20, the O RunddichtringO, 21, the O RunddichtringO, 22, the O RunddichtringO, 23, the trigger piece tongue, 24, trigger piece, 25, single running fire transaxle, 26, frizzen, 27, the rifle head, 28, the rifle lid, 29, pressing plate, 30, trigger piece tongue pin, 31, the trigger piece pin, 32, spring, 33, the rifle cancelling, 34, hollow pins, 35, the butterfly compressing tablet, 36, spring, 37, the security insurance trigger head, 38, brace, 39, attachment screw, 40, nail, 41, cartridge clip, 42, send nail-plate, 43, pull handle, 44, support, 45, valve, 46, gas nozzle cap, 47, piston.

Referring to Fig. 1, a kind of pneumatic nail gun, comprise housing 1, cylinder 3 and cylinder head 2, piston 47, cartridge clip 41, rifle head 27, striker 10, balanced valve 11, trigger piece 24, valve rod 18, valve 45 etc., the security insurance trigger head 37 additional trigger pieces 24 that start are housed on rifle head 27 finishes the work, as shown in Figures 2 and 3, trigger piece 24 and single running fire transaxle 25 Colaesce mutually change valve rod 18 turnover positions, and as shown in Figure 1, being equipped with on the cylinder head 2 to change exhaust cap 14.

As shown in Figure 1, security insurance trigger head 37 usefulness braces 38 are connected frizzen 26 with attachment screw 39, another termination trigger piece tongue 23 1 end points of frizzen 26, coming to replenish startup plate handle 24 like this finishes the work, be that security insurance trigger head 37 is not run into working substance, trigger piece tongue 23 is static, make valve rod 18 backward although pull the elastic force that trigger piece 24 can not overcome spring 32, promptly can not open valve, have only the security insurance trigger head 37 of working as to run into working substance, security insurance trigger head 37 makes 23 activities of trigger piece tongue then pull trigger piece 24 by frizzen 26 and finishes the work, that is to say, utilize security insurance trigger head 37 to draw into the secondary Push And Release, play safety effect, this is that prior art is unexistent.
