Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] It should be noted that when a component is considered to be “outside” another component, it may be directly attached to the outer surface of the other component or be spaced a preset distance from the outer surface of the other component. When a component is said to be "set on" or "mounted on" another component, it may be directly set on the other component or there may be intervening components at the same time. The terms "above", "inwardly" and simil...

Abstract

The invention discloses an air cylinder which comprises an arc-shaped cylinder body and a piston assembly, wherein an air cavity is formed in the arc-shaped cylinder body; the piston assembly is movably accommodated in the air cavity. The air cylinder further comprises a first bearing part; the first bearing part comprises a shell and a first magnet fixedly accommodated in the shell; the shell is mounted on the outer side surface of the arc-shaped cylinder body in a sliding manner; the piston assembly comprises a first piston and a second piston rotatably connected with each other; the first piston comprises a first connecting rod as well as a second magnet and a piston body sequentially fixedly arranged on the first connecting rod in a sleeving manner; the second piston comprises a second connecting rod as well as another second magnet and another piston body sequentially fixedly arranged on the second connecting rod in a sleeving manner; the second connecting rod is rotatably connected onto the first connecting rod; magnetism of each second magnet is opposite to that of the first magnet; and when external gas pushes the piston assembly to move from one end of the arc-shaped cylinder body to the other end of the arc-shaped cylinder body along the air cavity, the first bearing part can slide to the other end of the arc-shaped cylinder body from one end of the arc-shaped cylinder body on the outer side surface of the arc-shaped cylinder body along with the piston assembly.

Description

technical field [0001] The invention relates to an air cylinder, in particular to a rodless air cylinder driven by magnetic force. Background technique [0002] Cylinder is a common energy conversion device, which converts compressed air pressure energy into mechanical energy, and realizes linear reciprocating motion, swing, rotation or impact action. Existing cylinders include two types, namely rod cylinders and rodless cylinders. A rod cylinder generally includes a cylinder body and a piston rod accommodated in the cylinder body and capable of extending out of the cylinder body. The end of the piston rod protruding out of the cylinder body is connected to an external load for movement. Rodless cylinders include mechanical contact and magnetic drive. The mechanical contact rodless cylinder sets a chute in the axial direction of the cylinder tube, so that the piston and the slider move on the upper part of the chute. The magnetically driven rodless cylinder is magneticall...
