Description

Technical Field

[0001] This application relates to the technical field of cooking device components, specifically a hinge structure. Background Technology

[0002] Ovens, steamers, and other cooking appliances typically include a door and a cooking cavity for cooking food. The door is hinged to the cooking cavity to open or close it.

[0003] To ensure a smooth and easy opening and closing of the door, a spring is often installed inside the hinge to overcome the influence of the door's own weight on the opening and closing process. The spring is installed in the rotating part of the hinge of the door. When the door is opened, the spring pulls the door to prevent it from flipping and falling quickly due to gravity. When the door is closed, the spring rebounds and drives the door to retract and close the mechanism.

[0004] Springs are typically attached to a pivot within a hinge via hooks at both ends. Upon installation, the spring can extend and retract in conjunction with the pivot's rotation. Because the spring's tension and contraction forces are transmitted through the hooks, which are formed from a single spring wire with a small contact area, repeated stretching and retraction over long-term use can cause stress concentration and fatigue damage to the hooks, affecting the hinge's functionality.

[0030] As attached Figure 1-4 As shown, this application provides a hinge structure through the following technical solution, including:

[0031] Fixing part 1;

[0032] Rotating part 2 is rotatably connected to fixed part 1. Rotating part 2 is provided with receiving cavity 21. Receiving cavity 21 is provided with spring 22 and connecting rod 23. The upper end of spring 22 is connected to horizontal shaft 211 at the upper end of receiving cavity 21. The lower end of spring 22 is connected to the upper end of connecting rod 23. The lower end of connecting rod 23 is rotatably connected to fixed part 1 through first hinge shaft 212.

[0033] The upper end of the spring 22 is provided with a first connecting member 25. One end of the first connecting member 25 is sleeved on the spring wire 221 of the spring 22, and the other end of the first connecting member 25 is connected to the horizontal shaft 211; and / or

[0034] The lower end of the spring 22 is provided with a second connector 26. One end of the second connector 26 is sleeved on the spring wire 221 of the spring 22, and the other end of the second connector 26 is connected to the connecting rod 23 through the second hinge shaft 213.

[0035] Compared with the prior art, this application has the following beneficial effects: connecting parts are provided at both ends of the spring, and the spring is connected to the horizontal shaft and the second hinge shaft through the connecting parts. The connecting parts are sleeved on the spring wire, which increases the force-bearing surface of the spring, avoids the spring damage caused by stress concentration during repeated stretching and retraction, improves the service life of the spring, and improves the performance of the hinge.

[0036] In the embodiments applied in this application, for ease of installation and use, the first connector 25 and the second connector 26 are identical components. Thus, depending on actual usage requirements, either the upper end of the spring 22 is connected to the horizontal shaft 211 using the first connector 25, or the lower end of the spring 22 is connected to the connecting rod 23 using the second connector 26, or both the first connector 25 and the second connector 26 can be used simultaneously. This application preferably employs the simultaneous use of the first connector 25 and the second connector 26.

[0037] A first through hole 27 is provided at one end of the first connector 25 and the second connector 26. The spring wire 221 of the spring 22 passes through the first through hole 27, thereby connecting the first connector 25 and the second connector 26 to the spring 22. In order to increase the force-bearing surface of the spring 22, there are no fewer than two first through holes 27, so that the spring 22 is subjected to force by spring wires 221 at no fewer than two locations. In the embodiment of this application, there are three first through holes 27.

[0038] At the same time, at least two first through holes 27 are arranged radially along the spring 22, so that the two stress points of the spring wire 221 will not be concentrated on one side of the spring 22, but are located on opposite sides of the spring 22. This can keep the force direction of the spring 22 basically consistent with its axial direction, realize the accurate and effective extension and retraction of the spring 22, and avoid deformation and damage of the spring 22 due to deviation of the force direction.

[0039] In the embodiments applied in this application, the other ends of the first connector 25 and the second connector 26 are provided with a second through hole 28. The second through hole 28 of the first connector 25 is used to connect the horizontal shaft 211, and the second through hole 28 of the second connector 26 is used to connect the second hinge shaft 213.

[0040] For ease of installation and use, both the first connector 25 and the second connector 26 are sheet-like.

[0041] In the embodiments applied in this application, the lower end of the rotating part 2 is provided with a third hinge shaft 214, and the rotating part 2 is rotatably connected to the fixed part 1 through the third hinge shaft 214. The fixed part 1 is installed on the body of the cooking device, while the rotating part 2 is installed on the door of the cooking device. The door flips under the action of the rotating part 2 to open and close the body.

[0042] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
