Abstract
The invention provides a kind of air cylinder structure, air cylinder structure comprises cylinder block, piston and piston rod, and described cylinder block inside has chute, and chute is from the bottom of inwall along to top, and described chute is distributed in inwall circumference, is provided with multiple; Piston outer wall sectional shape is identical with cylinder block inner wall section geomery; Described internal piston has hollow structure, and described hollow structure is a disc-shaped structure, and the inside of hollow structure is provided with multiple supporting structure.This air cylinder structure, structure is simple, fin groove design between piston and cylinder block inwall, be conducive to the area of contact increased therebetween, be the convolution of gas, the beneficial effect that damper piston moves back and forth can be played, simultaneously, this structure can be placed piston, in cylinder block, radial rotary be occurred, internal piston hollow structure, is conducive to alleviating the overall weight of cylinder.
Description
Technical field
This patent relates to a kind of air cylinder structure.
Background technique
Existing cylinder piston is generally circle, the invention provides a kind of air cylinder structure, and the outer round surface of cylinder piston has multiple fin, cylinder piston is in movement process, and between cylinder wall, there is buffer function, reduce noise, can play preventing piston generation radial rotary simultaneously.
Summary of the invention
For solving above technical problem, the invention provides following technological scheme: a kind of air cylinder structure, described air cylinder structure comprises cylinder block, piston and piston rod, described cylinder block inside has chute, chute is from the bottom of inwall along to top, and described chute is distributed in inwall circumference, is provided with multiple; Piston outer wall sectional shape is identical with cylinder block inner wall section geomery; Described internal piston has hollow structure, and described hollow structure is a disc-shaped structure, and the inside of hollow structure is provided with multiple supporting structure.
Further, the top and bottom of described supporting structure support hollow structure, supporting structure is Cylindrical object, three supporting structure Parallel Design, and spacing is equal, and the two ends of supporting structure connect with the circumference of hollow structure.
Further, the top and bottom of described supporting structure support hollow structure, the cross section of supporting structure is square Cylindrical object, the quantity of supporting structure is the six roots of sensation, be laterally three parallel and spacing is equal, longitudinally three parallel and spacing is equal, the square crossing of multiple supporting structure transverse and longitudinal.
This air cylinder structure that the present invention relates to, structure is simple, fin groove design between piston and cylinder block inwall, be conducive to the area of contact increased therebetween, be the convolution of gas, the beneficial effect that damper piston moves back and forth can be played, simultaneously, this structure can be placed piston, in cylinder block, radial rotary be occurred, internal piston hollow structure, is conducive to alleviating the overall weight of cylinder.
