Embodiment Construction
[0011] like figure 1 , figure 2 as shown,
[0012] A windproof hinge for the door body of a box-type transformer, comprising a two-piece first hinge body 1 and a second hinge body 2, one end of the first hinge body 1 and one end of the second hinge body 2 are hinged, and at the hinge At least one hinge main body is provided with a limiting side plate 5, the other end of the first hinge main body is pivotally connected with the door shaft of the door body 6 through the first shaft hole 3, and the other end of the second hinge main body is connected to the box through the second shaft hole 4. Type transformer 7 bottom pins are hinged.
[0013] When the staff needs to open the door, they only need to open the door to a certain angle. Since the first hinge body 1 rotates around the axis through the shaft hole, the second hinge body 2 rotates around the shaft through the second shaft hole. When the two hinge bodies When being in a straight line, due to the existence of the limi...

The invention provides an anti-wind hinge for a door body of a box-type transformer. The anti-wind hinge comprises two sheet-like main bodies, i.e., a first hinge main body and a second hinge main body; one end of the first hinge main body is hinged with one end of the second hinge main body, and a limiting side plate is arranged on at least one hinge main body at a hinged position; and the other end of the first hinge main body is pivoted with a door pivot of the door body via a first axle hole, while the other end of the second hinge main body is hinged with a pin shaft at the bottom of the box-type transformer via a second axle hole. The anti-wind hinge is simple in structure and convenient to use; in a process of mounting and repairing the box-type transformer, the door body is fixed and is kept in an open state, so that the anti-wind hinge is convenient for a worker to mount or repair the transformer and is liable to promotion and application.
Description
technical field [0001] The invention relates to a door windproof fixing device, in particular to a windproof hinge on a box-type transformer door, and belongs to the technical field of design, manufacture and operation of box-type transformers. Background technique [0002] There are generally high and low voltage and transformer doors on the surrounding surfaces of the box-type transformer. During the installation and maintenance of the box-type transformer, in order to facilitate the installation or maintenance of the workers, the door is generally kept open. Install a windproof hinge to hold the door in place. [0003] The previous windproof hinge is to install a hook on the door body. The hook is provided with a hook shape at both ends of the rod, punch holes on the bottom of the box body and the door body, and hang between the two through a U-shaped round steel. It is inconvenient to operate, and the U-shaped round steel cannot be fixed, and it is easy to lose during p...
