Hinge

Abstract

The invention relates to a hinge, in particular to a hinge used between a furnace door and a furnace body of an electric steaming furnace. The hinge comprises a hinge rotating component, a hinge fixing seat (2) and a hinge positioning sheet (3), wherein the hinge rotating component comprises a shell (1), a positioning sheet connecting component (4) and a tension spring (5); the lower end of the positioning sheet connecting component (4) is connected with the hinge positioning sheet (3); the upper end of the positioning sheet connecting component (4) is connected with one end of the tension spring (5) through a tension spring lower end fixing rod (9); the side wall of the positioning sheet connecting component (4) is in sliding fit with a limit groove (11) on the shell (1) through a bulge; and the other end of the tension spring (5) is connected with a tension spring upper end fixing rod (8) on the shell (1). The hinge is characterized in that: a distance between the tension spring upper end fixing rod (8) and the tension spring lower end fixing rod (9) is greater than the length of the tension spring (5) in a natural state. The hinge for the electric steaming furnace has a reasonable structure and is higher in sealing property.

Description

Problems solved by technology

[0002] At present, electric steam ovens (including steam ovens, steamers, steam ovens, etc.) One end of the hinge positioning piece is detachably connected with the hinge fixing seat, and the other end of the hinge positioning piece is hinged with the hinge rotating assembly; the hinge rotating assembly includes a shell, a positioning piece connecting component and a tension spring, and the positioning piece is connected to the lower end of the component It is connected with the hinge positioning piece, and the upper end of the positioning piece connecting component is connected with one end of the tension spring through the lower end fixing rod of the tension spring. Extension spring lower end fixed rod, stage clip positioning block, stage clip and stage clip seat; The other end of extension spring links to each other with the extension spring upper end fixed rod on the shell; But the hinge commonly used in the prior art has following deficiencies: one, In the prior art, the hinge of the electric steamer is limited by the structural design, the tension of the extension spring cannot be well exerted, and the sealing performance is not good, so that the door of the electric steamer cannot be tightly pressed against the inner liner of the electric steamer. , there may be air leakage, and the leaked steam may burn the user, and because of the steam leakage, the heating time of the electric steamer is prolonged, resulting in an increase in power consumption of the electric steamer, resulting in a waste of energy

2. Most of the sliding fit parts between the side wall of the positioning piece connecting component in the hinge used in the prior art and the limit groove on the shell are directly exposed on the surface of the shell, which is easily affected by foreign objects and causes the sliding fit to fail, making the hinge unable to normal work

3. In the prior art, the hinge of the electric steam oven will produce noise after working for a period of time due to the lack of corresponding limit mechanism for the tension spring and other components.

4. In the prior art, the installation structure of the pressure spring in the connecting assembly of the hinge positioning piece of the electric steam oven is complicated, and the operation steps are various
