A SPACE SUPPORTER USE AIR CYLINDER

摘要

A space support is provided to allow a caliper to be easily inserted, operated, and released in a housing by separating a moving plate from a fixed plate by a predetermined distance by using air, or recovering the state of the plates to an initial state through an air discharging operation and a restoring force of a return spring. A cylinder(100) has an air outlet at a rear portion. A piston(200) is inserted into the cylinder(100). A cover member(300) is coupled with the cylinder(100) while covering a front end portion of the cylinder(100). A fixed rod(340) has the first end portion fixed to an exposure portion of the cover member(300) and the second end potion having a fixture plate(320) to maintain an interval. A moving rod(240) has the first end portion fixed to the piston(200) and the second end portion exposed to the cylinder(100) while passing through a central hole(380) of the cover member(300) and the fixed rod(340). The moving rod(240) has a moving plate(220) to maintain an interval at the exposed end portion. A return spring(400) has one side supported by the piston(200) and the other side supported by the cover member(300) in the cylinder(100). An air adjusting part(500) is coupled to an opened end portion of an air outlet(110) of the cylinder(100). The air adjusting part(500) includes an air intake port(520) to introduce air into the cylinder(100), an air outlet port(540) to discharge air, and a lever(560) to control the air intake port(520) and the air outlet port(540).
