Multi-link hinge device

Abstract

A multi-hinge hinge device is installed on an object body with a door and comprises a bottom connecting rod, a top connecting rod, a main body connecting rod, a first hinge piece, a second hinge piece, a third hinge piece and a locking arm. A first bottom assembly hole and a second bottom assembly hole are formed at one side of the end part of the bottom connecting rod at certain intervals, the top connecting rod is mounted on a door of the body, and a first top assembling hole and a second top assembling hole are formed at a certain interval; the main body first connecting rod end is connected with the first bottom assembling hole through a pivot, and the other end forms a first main body assembling hole and a second main body assembling hole inside; the first hinge piece is connected with the first top assembling hole and the first main body assembling hole through a pivot; the second articulation piece is connected with the second top assembly hole and the second main body assemblyhole through a pivot, and an articulation piece central assembly hole is formed in the inner side; the third articulation piece is connected with the articulation piece central assembly hole and the second bottom assembly hole through pivots; the locking arm is connected with the first hinge piece through a pivot, and when the top connecting rod for opening and closing the door acts, the door selectively moves to the door closing position through elastic guiding. And the top connecting rod selectively rotates and then is locked by an elastic action interval formed on the locking arm. The elastic part on the locking arm provides elastic force, and the door elastically moves in the elastic action section and is provided with a buckle part with a guiding function.

Description

technical field [0001] The present invention designs a multi-hinge hinge device, specifically a multi-hinge hinge device that can easily open or close the doors of household appliances, furniture and other objects in a narrow space. Background technique [0002] Generally speaking, home appliances and furniture with doors are composed of a main body and a door. The door and the main body are connected by hinges to perform switching operations. The main body can be opened or closed by turning the door. [0003] Among various object examples, such as refrigerators as an example, there is a utility model patent with the publication number of Korean No. 20-1999-0035936 in the related prior art, which is called a refrigerator door hinge device. [0004] But today's refrigerators are getting bigger and bigger, and the door of the refrigerator is also getting bigger, and the rotation range of the door on the body becomes larger. As a result, the installation space of the refrigerat...
