Oven hinge

Abstract

An oven hinge comprises a base fixed to a box body, and a support fixed to a door plate. A hinge arm is movably hinged to and installed on the head of the support. A buckle is arranged on the hinge arm and fixedly connected with the base. The oven hinge is characterized in that a containing groove is formed in the support, a pull arm is installed in the containing groove, a tension spring is arranged on the tail section of the pull arm and connected with a limiting nail on the tail section of the support, a limiting pin is arranged on the head of the pull arm and penetrates through and is inserted in a guide groove in the hinge arm, and a guide device is arranged between the pull arm and the support and conducts limiting so that the pull arm can only slide relative to the support in parallel in the containing groove. The oven hinge has the advantages that an oven door can stop at any angle when opened or closed, and the stop angle can be changed through the shape change of the unique kidney-shaped guide groove; when the oven door is completely closed or opened, the limiting pin or a wheel slides into a door closing groove part or a door opening groove part so that the oven door can be blocked.

Description

technical field [0001] The invention relates to a box hinge of a household appliance, in particular to an oven hinge. Background technique [0002] The door hinge of the existing cabinet basically relies on the tension or elastic force of the spring, and adopts the method of twisting and pulling. When the door needs to be opened, the furnace door is pulled open to lengthen or compress the spring, which can realize the opening of the furnace door. When it needs to be closed When the furnace door is closed, just let go, and the furnace door will be closed due to the reset action of the spring. In actual use, due to the certain acceleration of the spring reset, when the furnace door is about to close, it has the largest kinetic potential energy, the speed is also faster, and the sound of closing the door is relatively loud, and the box is easily damaged if it is subjected to such impact for a long time , the general method is to add shock absorbers on the door frame, such as s...

AI Technical Summary

Problems solved by technology

In actual use, due to the certain acceleration of the spring reset, when the furnace door is about to close, it has the largest kinetic potential energy, the speed is also faster, and the sound of closing the door is relatively loud, and the box is easily damaged if it is subjected to such impact for a long time , the general method is to add shock absorbers on the door frame, such as sponges, etc., but the tension spring of this method still has a lot of potential energy and is still easy to damage

Another method is to set guide rails, springs and rollers inside the hinge to cooperate with each other to achieve deceleration and pause, but its complex structure and relatively cumbersome installation lead to relatively high production costs
