Seat stand of marine propeller

Abstract

The invention relates to a seat stand of a marine propeller. The seat stand is improved on the basis of an existing base, a steering box, a movable plate, an operating handle and a connecting rod, that is, two side plates of the base are respectively provided with long holes extending in the length direction of the base. The seat stand further comprises a locking rod with two ends respectively inserted into the long holes in the corresponding side plates. The bottom of the steering box is further provided with a positioning groove matched with the middle of the locking rod, the two ends of thelocking rod are further separately hinged to the other ends of connecting rods on the corresponding sides, and an elastic member for moving the locking rod away from the connecting rods is disposed between the locking rod and the base. A first torsion spring is mounted on a third pin shaft, and a limit groove is formed in the edge of the movable plate toward the locking rod. When the movable plate is in an upright state, the locking rod is engaged in the limit groove. The seat stand is simpler in overall structure and flexible and free in action. Under the double action of the elastic memberand the first torsion spring, the movable plate is more reliable in positioning and more practical.

Description

technical field [0001] The invention relates to a seat platform, in particular to a seat platform of a marine propeller. Background technique [0002] A marine propeller is a power device that drives the hull forward. It includes a riser, a motor at the bottom of the riser and blades. The riser is fixed on the hull through a suspension frame, and is also supported on the hull through a seat, such as Chinese patent application publication number is CN200510062357.3, which discloses a seat platform. At this time, the riser is locked by the locking sleeve through the tooth sleeve and vertically passes through the steering box. The steering box is hinged in the base of the seat platform. , and through the multi-bar mechanism relative to the base, there are two working conditions: horizontal state and vertical state, so as to achieve the purpose of lifting the propeller to be in a non-working state and sliding down to be in a working state. [0003] The specific structure of the...

Problems solved by technology

With such a multi-bar mechanism, although the propeller can be fixed and slid down, due to the multi-link transmission mode, the overall structure is relatively complicated, and the relative movement between the connecting rods will inevitably cause mutual conflicts. The defects of noise caused by internal and external shaking, and the positioning stability of the movable plate also need to be further improved
