Automatically closed monorail hinge by means of gravity

Abstract

The invention discloses an automatically closed monorail hinge by means of gravity. The automatically closed monorail hinge by means of gravity comprises a mounting plate and a gate slot block. A rotating groove is formed in the gate slot block, a fixed axle block hole and an axle sliding bending groove are separately formed in two sides of the bottom of the rotating groove, a gasket axle and a sliding axle are vertically fixed in front of and behind the top surface of the mounting plate in a spaced manner, the top end of the sliding axle is slidably inserted into the axle sliding bending groove, a connecting plate is horizontally and rotatably arranged on the rod wall of the gasket axle in a sleeving manner, a fixed axle is rotatably fixed to the top surface of the outer side end of the connecting plate, the top end of the fixed axle is slidably inserted into the fixed axle hole, a slot slope is arranged on the bottom surface of the axle sliding bending groove, a gravity slide block is connected between the top of the slot slope and the inner wall of the rotating groove in a clamped manner, and a gravity bevel slidably connected to the slot slope is arranged on the top surface ofthe gravity slide block. A door body is closed automatically by means of gravitational potential energy by matching with structural characteristics of the monorail hinge, so that the integral structural dimension of the monorail hinge is simplified, and the automatically closed monorail hinge by means of gravity further has a cost advantage and is small in mounting space occupied.

Description

technical field [0001] The invention specifically relates to a monorail hinge, in particular to a gravity self-closing monorail hinge. Background technique [0002] Monorail hinges generally refer to the hinge structure that can realize the segmental opening and closing of the door body, and generally include curved guide rails that can drive the segmental opening and closing of the door body. They are all opened and closed manually. For the application scenarios of refrigerators, in order to prevent the refrigerator door from being opened for a long time to consume electricity, it is generally equipped with an automatic door closing mechanism. The general automatic door closing mechanism often uses a damping or spring return mechanism. When the box door is opened by force, it stores potential energy, and then pulls it back and closes in the horizontal direction. However, these return mechanisms are generally difficult to combine with the structure of the monorail hinge, and...

[0002] Monorail hinges generally refer to the hinge structure that can realize the segmental opening and closing of the door body, and generally include curved guide rails that can drive the segmental opening and closing of the door body. They are all opened and closed manually. For the application scenarios of refrigerators, in order to prevent the refrigerator door from being opened for a long time to consume electricity, it is generally equipped with an automatic door closing mechanism. The general automatic door closing mechanism often uses a damping or spring return mechanism. When the box door is opened by force, it stores potential energy, and then pulls it back and closes in the horizontal direction. However, these return mechanisms are generally difficult to combine with the structure of the monorail hinge, and it is often necessary to add additional auxiliary mechanisms, which occupy more installation space and have a cumbersome structure.
