Technical field
The utility model relates to air tool gas pin gun, particularly a kind of drive unit of gas pin gun firing lock.
Background technology
The existing drive unit of Chang Yong gas pin gun firing lock, be to use guard linkage and trigger gear interlock, come driving switch thimble assembly to realize the percussion nailing by sheet in the trigger in the trigger gear, can pull the trigger nailing continuously by knocking the guard linkage, as shown in Figure 1, the structural representation of the drive unit of gas pin gun firing lock in the prior art, comprise guard connecting rod 10, trigger main body 20, sheet 30 in the trigger, in this figure, switch dome needle assemblies 40 is in not duty.As shown in Figure 2, fasten trigger main body 20 earlier, do not knock guard connecting rod 10, sheet 30 can not driving switch thimble assembly 40 in the plate machine, and switch dome needle assemblies 40 also is in the state of percussion.As shown in Figure 3, fasten trigger 20 earlier, knock guard connecting rod 10, sheet 30 driving switch thimble assemblies 40 in the trigger, switch dome needle assemblies 40 is in the percussion state.As shown in Figure 2, when unclamping guard connecting rod 10, sheet 30 breaks away from driving switch thimble assembly 40 in the trigger, and switch dome needle assemblies 40 recovers the state of not pulling the trigger.If when locating the back and only pulling the trigger a nail, as shown in Figure 4, locate with guard connecting rod 10 front end conflict workpiece earlier, the rear end moves upward and props up sheet 30 in the trigger, do not fasten trigger main body 20, sheet 30 can not driving switch thimble assembly 40 in the trigger, and switch dome needle assemblies 40 is in the state of percussion.Fasten trigger 20 and promptly enter percussion state (as shown in Figure 2).Because the power of shaking behind the nailing is big, guard connecting rod 10 can vibrate, and the operator is difficult to control, double hit can occur, sends two to three support pins continuously, does not reach the work purpose of location nailing.Therefore, when needing control location percussion one support pin, must change the switch dome needle assemblies in the switching device, usually need to change the long switch thimble of size, could carry out (another rifle just), but after changing, the purpose that just can not knock continuous nailing, thereby in practical operation, cause very big difficulty and inconvenient for the operator, greatly influence its operating efficiency.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, propose a kind ofly can pull the trigger nailing continuously by knocking the guard connecting rod, can locate the drive unit of the pneumatic nail gun firing lock of click (playing a nail) again, be convenient to the operator and manipulate, also improved it effectively simultaneously and increased work efficiency.
In order to realize above-mentioned technical purpose, the utility model is realized by following technical scheme:
A kind of drive unit of gas pin gun firing lock, comprise the guard linkage, trigger gear and switch dome needle assemblies with the interlock of guard linkage, described guard linkage comprises guard and guard connecting rod, described trigger gear comprises the trigger main body and is used for the interior sheet of trigger of percussion switch thimble assembly, described guard connecting rod is provided with chute, be provided with the compression spring in this chute, the outer race corresponding to chute at the guard connecting rod is connected to slide block, be articulated with bearing pin on the described slide block, this bearing pin passes slide block, chute also is positioned at the tip position that compresses spring, because the elastic reset effect of compression spring, the slide block that can guarantee to be socketed on the guard connecting rod is pushed up the top.Simultaneously, owing to be articulated with bearing pin on the slide block, this bearing pin passes slide block, chute, is convenient to slide block and is sliding along chute again.Described slide block inside also is provided with the centre bore that is used for socket guard connecting rod and cooperates with guard connecting rod and compression spring.In addition, the top of described slide block is provided with first boss, also is provided with second boss that fastens mutually with first boss on the described trigger main body, and above-mentioned two boss fasten mutually when sending out (playing a support pin) clicking.
In order to guarantee in the trigger that sheet can pull the trigger when the percussion switch thimble assembly smoothly, can avoid the open slot of second boss on the trigger main body when sheet is provided with percussion switch thimble assembly in the described trigger.
Flexibly connect by pin between the sheet in described trigger main body and the trigger.
For location and installation slide block preferably, the dual-side of described slide block respectively is provided with an installing hole.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model can knock nailing or location continuously and click the operation of sending out (playing a support pin) by the sequencing of operation guard linkage and trigger gear.
(2) the utility model can realize that the guard connecting rod is pulled the trigger nailing continuously and the conversion of sending out between (playing a nail) is clicked in the location by knocking to gas pin gun with one, and the handled easily person uses, and increases work efficiency.
