Title:
DISMOUNTING DEVICE FOR AIR CYLINDER COVER
Document Type and Number:
WIPO Patent Application WO/2021/232545
Kind Code:
A1
Abstract:
Disclosed by the present invention is a dismounting device for an air cylinder cover. The number of limiting moving holes is the same as the number of sides of a connecting column. U-shaped limiting moving ejector blocks cooperating with the limiting moving holes elastically move in the limiting moving holes in the radial direction, openings of the limiting moving ejector blocks being outward. Inner side ends of the limiting moving ejector blocks vertically abut against end faces of the corresponding sides of the connecting column. Upper end faces of the limiting moving ejector blocks abut against a bottom face of a hand wheel body. A limiting ring in a circular column shape is sleeved on the connecting support vertically. Multiple lifting drive plates distributed circumferentially and evenly are formed on the bottom face of the limiting ring. Cylindrical drive columns are formed on front end faces and rear end faces of the lifting drive plates. The lifting drive plates are arranged in the openings of the limiting moving ejector blocks such that the lifting drive plates move vertically. Drive holes which incline upwards from outside to inside and cooperate with the corresponding drive columns are formed in a pair of transverse portions of each limiting moving ejector block.
