An exhibition liquid crystal display screen dual-pole positioning mechanism, comprising two metal upright poles (1) arranged in parallel, characterized in that the two metal upright poles (1) are each provided with a sleeve connector (2) at a same height, each sleeve connector (2) has provided on the inner wall thereof several magnetic blocks that magnetically fix the connector onto the corresponding metal upright pole (1); and further comprising a support base bar (3) arranged between the two sleeve connectors (2), where either extremity of the support base bar (3) is pivotally connected to the corresponding sleeve connector (2) via a self-locking rotary ratchet mechanism (a), and a liquid crystal display screen mounting plate (4) is fixed on the support base bar (3). The positioning mechanism is structurally simple and convenient to install, facilitates positioning of a liquid crystal display screen, and allows flexible adjustment of the placement height and front/rear tilt angle of the liquid crystal display screen. |
