Abstract

A flexible locking structure for hinge connection of an exploration equipment support comprises a fixed ring (1). Hinge connection recesses (2) are provided on a surface of the fixed ring (1). The three hinge connection recesses (2) form an annular array centered around the axis of the fixed ring (1). A fixed shaft (3) is fixedly connected to an inner wall of the hinge connection recess (2). Support legs (4) are hinge-connected to a surface of the fixed shaft (3). A position-limiting block (5) is fixedly connected to a surface of the support leg (4). A surface of the position-limiting block (5) is arc-shaped. A through-hole (6) is provided on the surface of the position-limiting block (5). A steel cable (7) is slidably connected to an inner wall of the through-hole (6). In the flexible locking structure for hinge connection of an exploration equipment support, a locking device is provided, such that during use, the length of the unwound steel cable is controlled by means of a rotary shaft (8), thereby controlling a maximum angle formed by the support legs (4). A surface of an insertion plate (20) engages with a surface of a ratchet wheel (15), so as to prevent the rotary shaft (8) from rotating reversely, thereby locking a length of the steel cable (7) outside a fixed box (9), facilitating adjustment of an angle formed by the support and the support leg (4), and achieving locking after adjustment.
