Description
Technical field
The utility model relates to a kind of resetting means, refers to a kind of spring reverse motion for piston mechanism especially.
Background technique
Gas pin gun generally adopts piston as power plant, piston movement is promoted by air pressure, nail penetrates by the high-speed motion of piston, and completing nailing action back piston needs to reset to prepare next nailing, therefore needs to design the reset of a kind of resetting means for piston.
Model utility content
The utility model proposes a kind of spring reverse motion for piston mechanism, can realize the Rapid reset of piston mechanism, its technological scheme is achieved in that
A kind of spring reverse motion for piston mechanism, comprise piston body and be arranged on the spring reverse motion above piston body, described spring reverse motion comprises contiguous block, pull bar, Returnning spring and support, described Returnning spring two ends connect contiguous block and support respectively, pull bar is fixedly connected with below described contiguous block, described support is fixedly connected on above piston body, and described pull bar end gos deep in piston body.
As further improvement of the utility model, the two ends of described Returnning spring are provided with hook part, and are rotatably connected on contiguous block and support respectively by latch.
As further improvement of the utility model, the both sides of described pull bar are respectively provided with a Returnning spring.
As further improvement of the utility model, described Returnning spring is torsion spring or stranded wire helical spring.
As further improvement of the utility model, described piston body comprises piston/cylinder, piston sheet and piston rod, is threaded connection below described piston sheet with piston rod.
As further improvement of the utility model, described pull bar upper end is threaded with contiguous block, and lower end is connected with piston rod thread.
As further improvement of the utility model, described piston/cylinder bottom is also provided with buffer stopper, and described buffer stopper is provided with through hole, and described piston rod stretches out piston/cylinder outside from through hole.
The beneficial effects of the utility model are:
This spring reverse motion structure is simple, cheap for manufacturing cost, and uses reliable and stable, effectively can complete the reset of piston mechanism.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.
As shown in Figure 1, a kind of spring reverse motion for piston mechanism, comprise piston body 1 and be arranged on the spring reverse motion 2 above piston body 1, piston body 1 comprises piston/cylinder 11, piston sheet 12 and piston rod 13, and spring reverse motion 2 comprises contiguous block 21, pull bar 22, Returnning spring 23 and support 24.
Returnning spring 23 two ends are equipped with hook part 25, and this hook part 25 is connected on contiguous block 21 and support 24 by latch 3, and Returnning spring 23 can rotate around latch 3 and stretch or compress, and respectively arranges a Returnning spring 23 in this way in pull bar 22 both sides.Wherein, Returnning spring 23 can adopt torsion spring or stranded wire helical spring, and above-mentioned two kinds of springs are prior art.Certainly, sheathed helical spring on pull bar 22, make helical spring withstand between contiguous block 21 and cylinder cap 14, the elastic force after being compressed by helical spring is also the reset that can realize pull bar 22.
Be threaded connection pull bar 22 below contiguous block 21, support 24 is fixedly connected on the cylinder cap 14 of piston body 1, and pull bar 22 end gos deep in piston body 1, and is threaded with piston rod 13.
The top of piston rod 13 is provided with internal thread and outside thread, is connected with pull bar 22 by internal thread, is connected with piston sheet 12 by outside thread.
Piston/cylinder 11 bottom is also provided with buffer stopper 15, and buffer stopper 15 is made up of rubber or nylon material, can play buffering and position-limiting action to the impact of piston sheet 12.Buffer stopper 15 center is also provided with through hole 16, and it is outside that piston rod 13 stretches out piston/cylinder 11 from through hole 16.
Working principle of the present utility model is:
When piston rod 13 moves to bottom piston/cylinder 11, need to reset and could continue next action, at this moment just need resetting means 2 pairs of piston rods 13 to reset.Piston rod 13 under external force (as pressurized gas, steam power or other machine powers) moves to bottom piston/cylinder 11, and pull bar 22 also can move downward with piston rod 13 and compression reseting spring 23; When external force disappears, pull bar 22 will move upward in the elastic force effect of Returnning spring 23 and get back to initial position, thus drives piston rod 13 to move upward and get back to the top of piston/cylinder 11, for next action is ready.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
