徴とする一製図台などにおける昇降支柱のロック機構。It consists of an outer cylinder and an inner cylinder that is inserted into the outer cylinder and moves up and down.A bulge is formed on one wall surface of the inner cylinder along its length, and an outer cylinder that faces this is formed. A rotating shaft, which is rotated by an external operation, is attached to the wall surface so as to be rotatable and movable in the axial direction, and a cam plate having a cam portion that rides on the bulged portion is fixed to the inner end of the rotating shaft. , a thrust bearing fitted to the rotating shaft and a pressure contact plate are interposed between the cam plate and the outer cylinder wall surface facing the cam plate, and the cam portion bulges when the rotating shaft is rotated. Due to the movement of the rotating shaft in the axial direction when riding on the part, the other wall surface of the inner cylinder opposite to the wall surface having the bulged part is pressed against the inner wall surface side of the outer cylinder opposite thereto, The cam plate is in pressure contact with the pressure contact plate via the thrust bearing, and the pressure contact plate is further configured to be adjustable in the axial direction of the rotation shaft by an adjustment screw attached to the outer cylinder side. Features: 1. A locking mechanism for lifting columns on drafting tables, etc.
