Oven hinge with friction balance mechanism

Abstract

The invention relates to the technical field of hinges, and discloses an oven hinge with a friction balance mechanism. The oven hinge comprises two connecting arms connected to an oven door and an oven cabinet correspondingly, wherein the two connecting arms include a long arm and a short arm, and one end of the long arm and one end of the short arm are rotatably connected to each other; and the friction balance mechanism for balancing the weight of a door body after the oven door is opened is connected between the long arm and the short arm, the friction balance mechanism includes a fixed friction pair, a movable friction pair and an elastic expansion and contraction element, wherein the fixed friction pair and the movable friction pair are in contact with each other, the elastic expansion and contraction element acts between the long arm and the short arm, the fixed friction pair is fixedly connected to the long arm, the movable friction pair is connected to the elastic expansion and contraction element, and tight adhesion and slip of a friction head of the movable friction pair on the fixed frication pair are realized through the elastic acting force of the elastic expansion and contraction element. The reliability of the use of the oven hinge is improved.

Description

technical field [0001] The invention relates to the technical field of hinges, in particular to an oven hinge with a friction balance mechanism. Background technique [0002] An oven is an appliance used to bake food or dry products. The oven hinge is a connecting component used to connect the oven door and the oven cabinet in the oven. [0003] In the prior art, a typical oven hinge includes a door connecting arm used to connect the oven door, a cabinet connecting arm used to connect the oven cabinet and is rotatably connected to one end of the door connecting arm, and the door connecting arm There is also a spring tensioning component between the connecting arm of the cabinet body. Through the mutual balance between the spring force on the spring tensioning component and the self-weight of the oven door, the closing and locking of the oven door and the automatic suspension of the oven door in the half-open state are realized. stop. [0004] However, for the oven hinge o...

Problems solved by technology

[0004] However, for the oven hinge of the above structure, due to certain weight errors and assembly size connection errors in the oven door during production, some oven doors cannot be completely balanced with the spring force in mass-produced ovens. The stiffness of the spring will change after frequent opening and closing, which also affects the balance between the spring force and the oven door's own weight, thus reducing the reliability of the oven hinge.
