CONSTANT FORCE LIFTING ROD

摘要

A constant force lifting rod consists of a rod body (1) and a shower head fixing seat (2) sleeving the rod body (1). A sleeve seat (211) for fixing a shower handle is provided outside the shower head fixing seat (2). The shower head fixing seat (2) comprises a sliding seat upper cover (21), a sliding seat lower cover (22), a floating block (23), a wedge block (24), a return spring (25) and a force positioning spring (26). The floating block (23) sleeves the rod body (1). A wedge (241) is formed by the upper part of the wedge block (24), and a friction sheet (242) is provided in the inner side of the wedge (241).When it is in the normal state, with the effect of the force positioning spring (26), the wedge block (24) approaches the conical surface of the sleeve seat (231) under the action of the stretching force of the return spring (25), and the friction sheet (242) contacts the rod body (1) to cause the friction force, then the whole shower head fixing seat is fixed on the rod body (1).
