Two-way buffer oven hinge with automatic closing and hovering functions

Abstract

The invention provides a two-way buffer oven hinge with automatic closing and hovering functions. The two-way buffer oven hinge comprises a hinge seat and a hinge arm. The hinge arm is hinged to the hinge seat through a hinge shaft, the hinge seat is provided with a transmission elastic component and a two-way buffer component. The transmission elastic component comprises a positioning frame, a swing frame, a transmission rod and a transmission spring. A sliding connection part and a connecting combination groove are installed between the swing frame and the positioning frame. The connecting combination groove comprises a hovering arc groove and a fastening groove position, the sliding connection piece is slidably installed on the hovering arc groove or the fastening groove position with the rotation of the hinge arm to strengthen the tightness of closing and further facilitate the opening and closing of a door, the operation is convenient, the two-way buffering function can be realized when the door is opened and closed, the stationarity of the structure is improved, an oven door body stays in any position when the oven door body is opened, the use is flexible, and the use effectof an oven is ensured.

Description

technical field [0001] The invention relates to the technical field of oven hinges, in particular to a two-way buffer oven hinge with automatic closing and hovering functions. Background technique [0002] The oven hinge generally includes a swing arm, a base, a spring, and a pull rod. The swing arm is installed on the oven door, the base is installed on the oven cabinet, the swing arm and the base are hinged, the spring is sleeved on the pull rod, and the pull rod is connected to the base and the swing arm. Then, relying on the pulling force or elastic force of the spring, using the way of twisting and pulling, when opening the door, the spring can be stretched or compressed by pulling the door open, so as to realize the opening of the oven door; when closing, just let go of the oven door, and the oven door will open Closed on the oven cabinet due to the return action of the spring. [0003] Yet there is following deficiency in the oven hinge of above-mentioned structure: ...

AI Technical Summary

Problems solved by technology

[0004] 1. The dynamic closing force cannot be provided, and an external force or a spring with strong elasticity is required, which makes the opening and closing of the oven door laborious and cumbersome to operate;

[0005] 2. When the oven door is closed, there will be a large collision sound with the oven cabinet due to the elastic return of the spring, which is loud and easy to damage the oven; therefore, changing the spring and reducing the elastic coefficient of the spring is difficult to ensure the safety of the oven door. At the same time, when it is opened, it will be difficult for the spring to balance the weight of the oven door, so that the oven door will be opened too quickly, which will also damage other transmission parts of the oven and affect the normal use of the oven;

[0006] 3. The use state of the oven door is limited, that is, it can only be fully opened or completely closed. It is difficult to stop the oven door arbitrarily according to the actual application, which affects the use effect
