Abstract:
A height-adjustable hanging light, comprising a light body (27); a mounting base (28) is provided at the top of the light body (27), adjustment devices (29) are fixedly connected within the mounting base (28), the adjustment devices (29) each comprise an upper cover body (1) and a lower cover body (2), a spool (3) is provided between the upper cover body (1) and the lower cover body (2), a rotary shaft (4) is rotatably connected to the middle portion of the spool (3), a coil spring (5) is sleeved on the outer side of the rotary shaft (4), two ends of the coil spring (5) are fixedly connected to the inner wall of the spool (3), a return blocking plate (6) is provided at the top of the spool (3), the return blocking plate (6) is fixedly connected to the outer side of the rotary shaft (4), a return blocking block (7) is fixedly connected to the outer side of the return blocking plate (6), and a limiting plate (8) is provided on the outer side of the return blocking plate (6). Electrical connection between conductive posts (12) and a conductive base (14) is achieved by means of a dual-wire opening and pin contact manner, so that power supply wires (17) can be effectively energized, facilitating mounting; by means of a brake pad principle, the power supply wires (17) are controlled to slide downwards and rotate back; in addition, a friction force is increased in conjunction with an arc-shaped face of a guide plate (26), so that the weight of the light body (27) is balanced to maintain a vertical operation position of a lamp.
