Abstract
The utility model relates to a connecting hinge for opening the flap valve of a buoyancy tank, and belongs to a hinge. The connecting hinge mainly solves the technical problems of single connection method, complex installation, high head loss, and the like of the buoyancy tank door of the traditional valve. The technical scheme puts emphasis on that the connecting hinge comprises a hinge lug (1), a pin shaft (2) and a spacer (5), wherein the hinge lug (1) is internally provided with the pin shaft (2); one end of the pin shaft (2) is arranged into a semicircular head shape; the spacer (5) is arranged above a semicircular head end; and a lining (4) can be arranged between the hinge lug (1) and the pin shaft (2). The connecting hinge disclosed by the utility model can play a support role by arranging one end of the shaft pin (2) into the semicircular head shape and arranging the semicircular head end on a stress end according to a mechanics principle, can enable the buoyancy tank to achieve the purposes of closing and opening depending on the horizontal component of self gravity by reducing the friction force when being arranged into the condition of being tilted at a certain angle and is mainly used for connecting the buoyancy tank door when opening the flap valve of the buoyancy tank.
Description
Technical field
The utility model relates to a kind of hinge, and particularly a kind of buoyancy tank flap valve valve of opening connects hinge.
Background technique
At present, connect hinge and use the cylindrical body pivot pin mostly, hinge can only level or is vertically placed, and frictional force is big when tilting component is provided, and may cut with scissors dead.
Summary of the invention
The purpose of this utility model provides that a kind of installation is simple, practicality is driven buoyancy tank flap valve valve flexibly and connected hinge.
The technological scheme that its technical problem that solves the utility model adopts is: it comprises hinge ear 1, bearing pin 2 and pad 5, is provided with bearing pin 2 in the hinge ear 1, and bearing pin 2 one ends are arranged to the semicircle capitiform, are provided with pad 5 above the semicircle head end.Also can between hinge ear 1 and bearing pin 2, be provided with lining 4.Or all be provided with end cap 7 at the two ends of hinge ear 1, end cap 7 with cut with scissors ear 1 usefulness bolt 6 and be connected.
The beneficial effects of the utility model are: according to mechanics principle, the semicircle head end is arranged on the force side, can plays a supportive role, when being arranged to the situation of several angle, the power of reducing friction can make the buoyancy tank door rely on the horizontal component of self gravitation to reach and close and the purpose of opening.
