Technical field
The present invention relates to air spring technical field, particularly a kind of air spring structure that can effectively prevent that piston rod from rotating.
Background technique
Air spring is as conventional machinery component unit, and common by people, it is widely used in the every field such as medical apparatus, furniture and auto parts machinery, generally usings oil, gas or gas mixture as transmission medium in air spring.Existing air spring is generally by cylinder body, protecgulum, and bonnet, the piston and the piston rod that are provided with in cylinder body form, and its piston and piston rod can rotate under the effect of external force, at some in particular cases, the impact of making troubles to the connection of mechanical part.For effectively overcoming this deficiency, in row, many significant explorations have been done, as inboard wall of cylinder block cross section is provided with to polygonal, the cross section of piston is also made as polygonal, although this structure has effectively solved the rotation of piston and piston rod, it is complicated that production technology becomes, and cost of production first mate improves.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, provide a kind of simple in structure, fabricating cost is low, and can effectively prevent the air spring structure that piston rod rotates.
For achieving the above object, the present invention is by the following technical solutions:
A kind of anti-rotation air spring structure of the present invention, comprise cylinder body, piston and piston rod, described cylinder body one end is provided with rear end cover, and rear end cover is provided with pore one, and the described cylinder body the other end is provided with front cover, front cover is provided with pore two, described piston is slidably located in cylinder body, and described piston rod one end is fixedly connected with piston through front cover, and described piston rod stretches out on one end of front cover and is arranged with spline actuation mechanism.
Wherein, described spline actuation mechanism comprises spline sleeve, and on described spline sleeve lining, corresponding both sides are respectively equipped with draw-in groove, and in two draw-in grooves, correspondence is provided with through hole and slot respectively; One end that described piston rod stretches out front cover is provided with locating slot, is provided with spline sheet in locating slot, and described spline sheet two ends are arranged in two draw-in grooves.
Further, described piston outer wall is provided with wear-resistant strip and C type circle.
Further, described side face of piston ring is provided with crashproof pad.
Further, the inwall of described front cover is provided with dust ring and bearing.
Adopt after said structure, beneficial effect of the present invention is: piston rod of the present invention stretches out on one end of front cover and is arranged with spline actuation mechanism, can effectively prevent that piston rod and piston from rotating in movement process, solve deficiency and the defect of existing middle existence, widened application of the present invention and application area.The present invention is simple in structure, and fabricating cost is low, is conducive to apply.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1 to Figure 3, a kind of anti-rotation air spring structure of the present invention, comprises cylinder body 5, piston 4, and piston rod 6 and spline actuation mechanism, above-mentioned several parts form agent structure of the present invention.
Described cylinder body 5 one end are provided with rear end cover 1, and rear end cover 1 is provided with pore 1, and pore 1 is for the present invention is fully lost heart, for piston 4 motions provide power.Described cylinder body 5 the other ends are provided with front cover 8, and front cover 8 is provided with pore 27, and pore 27 effects are identical with pore one 2 effects.
Described piston 4 is slidably located in cylinder body 5, and described piston rod 6 one end are fixedly connected with piston 4 through front cover 8.Described piston 4 outer walls are provided with wear-resistant strip 13 and C type circle 14, main raising piston 4 wear-resisting propertys of described wear-resistant strip 13; The effect of described C type circle 14 is to avoid piston 4 both sides report gases that string leakage occurs.
Described piston 4 both ends of the surface are provided with crashproof pad 3, to avoid in movement process and rear end cover 1 and front cover 8 generation strong collision.
The inwall of described front cover 8 is provided with dust ring 9 and bearing 10, and dust ring 9 enters to prevent dust, and bearing 10 is to improve mobility of the present invention.
Described piston rod 6 stretches out on one end of front cover 8 and is arranged with spline actuation mechanism, to prevent that piston rod 6 and piston 4 from rotating in movement process.Particularly, described spline actuation mechanism comprises spline sleeve 11, on described spline sleeve 11 inwalls, corresponding both sides are respectively equipped with draw-in groove 17, interior corresponding through hole 12 and the slot 16 of being provided with respectively of two draw-in grooves 17, one end that described piston rod 6 stretches out front cover 8 is provided with locating slot 18, in locating slot 18, be provided with spline sheet 15, described spline sheet 15 two ends are arranged at respectively in two draw-in grooves 17.
Described spline sheet 15 two ends are located at respectively in two draw-in grooves 17, can effectively prevent that piston rod 6 from rotating in movement process.Spline sheet 15 of the present invention is after long-time use, can there are certain wearing and tearing, can cause location inaccurate, like this, the present invention need change spline sheet 15, and the method for specifically changing is as follows: when spline sheet 15 moves to slot 16 opposite position with piston rod 6, available thimble is by one end of through hole 12 top spline sheets 15, spline sheet 15 can be extruded from slot 16, changes after new spline sheet 15, from slot 16, inserts.
The present invention is simple in structure, easy to operate, and in terms of existing technologies, fabricating cost first mate reduces, and is conducive to apply.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
