TUBE ELEMENT AND CORRESPONDING TUBE ORGAN

Abstract

The tube element comprises convex edges and grooves distributed alternately in the circumferential direction of a wall of the tube element, a circular locking hole being arranged at the groove, and a clamping hole being formed in the convex edge; the tube member (200) comprises a base body, a pressing plate, a locking bolt articulated on the pressing plate by means of a first pin shaft, and a torsion spring connected to the base body and the pressing plate by a second pin shaft. In its natural state, the torsion spring propels the locking bolt to extend the through hole and is inserted into the locking hole to achieve radial locking; when the pressing plate is pressed, the locking bolt retracts to achieve unlocking.
