Kind Code:
A1
Abstract:
A bar rotation preventing device comprises a bar A (1) and a bar B (2) arranged adjacently vertically and mutually connected, and an adjustment device arranged in the bar B. The adjustment device comprises a guide bar (3) arranged inside the bar B, a plurality of protruding blocks (5), and a button inserted into a matching through hole (10). The guide bar comprises an upper end in the shape of a round platform, and a side wall having a plurality of guide tracks (7) disposed thereon, and a lower portion having an inverted triangular accommodation cavity (11) provided thereat and corresponding to a location of the through hole. Sliding blocks (8) are configured to fit on the guide tracks and are arranged at bottoms of sides of the plurality of protruding blocks and close to an axis line of the bar B. One end of the button is positioned outside the bar B, while the other end is positioned inside the bar B and embedded and fit in the matching accommodation cavity. In a normal state of the bar rotation lock device, the protruding blocks are inserted and fit in recessed holes of the bar A, effectively preventing rotations between the bars A and B. In an adjustment state, the guide bar is configured to move downwards by pressing the button, and in turn, the protruding blocks are driven to move toward a center of the guide bar B, and consequently the bars A and B can rotate.
