Abstract
Description
Technical Field
[0001] The utility model relates to an oven door hinge, in particular to a mounting structure between the oven door hinge and a door body. Background Art
[0002] In traditional oven designs, the hinges of oven doors are usually fixed with screws. Although this method is widely used, it has a series of problems and inconveniences.
[0003] First, the use of screws to fix the hinge arm requires precise alignment and installation, a process that usually requires professional tools and certain technical knowledge. This not only complicates the initial installation process, but also brings inconvenience during subsequent maintenance and replacement work. For example, when the oven door needs to be disassembled for repair, replacement of parts or deep cleaning, users or maintenance personnel need to spend extra time and effort to remove and reinstall these screws, which greatly reduces maintenance efficiency.
[0004] Secondly, the stability of the screw connection cannot be ignored. During long-term use, due to the frequent opening and closing of the oven door, the screw connection may gradually loosen, which will not only reduce the stability of the hinge arm, but also in extreme cases may cause the oven door to fall off, posing a threat to the user's safety. In addition, loose screws may also cause increased noise when the hinge is operated, affecting the user experience.
[0005] Furthermore, the method of fixing screws also has problems in terms of cleaning and hygiene. Food residues and grease will inevitably be produced during the use of the oven, and these residues are easy to accumulate at the screw and hinge joints, making them difficult to clean. The long-term accumulation of dirt not only affects the appearance and hygiene of the oven, but may also become a breeding ground for bacteria, so it is necessary to make further improvements. Utility Model Content

DETAILED DESCRIPTION
[0022] The utility model is further described in detail below with reference to the accompanying drawings. A mounting structure between an oven door hinge and a door body, characterized in that: it comprises a main arm body 2 fixed to a box body 1 and a hinge arm 4 fixed to a box door 3, the hinge arm 4 being rotatably hingedly mounted on the main arm body 2 via a hinge shaft 6, the box door 3 drives the hinge arm 4 to rotate around the hinge shaft 6, thereby realizing the opening and closing of the box door 3;
[0023] The hinge arm 4 is also swingably hingedly mounted with a safety plate 7, the lower end of which is provided with a buckle slot 71. When the hinge arm 4 is opened, the buckle slot 71 is clamped on the main arm body 2 to limit the hinge arm 4 to be in an open state.
[0024] The safety piece 7 is also provided with a hook 72. Correspondingly, a limit seat 31 is provided on the door 3. After the door 3 is docked with the hinge arm 4, the hook 72 is hooked into the limit seat 31 to prevent the door 3 from being separated from the hinge arm 4.
[0025] A guide tube 8 is installed on the inner end surface of the box door 3 , and an opening is provided on the lower end surface of the guide tube 8 . The hinge arm 4 is inserted into the guide tube 8 through the opening and connected to the box door 3 .
[0026] The limiting seat 31 of the box door 3 is set at the opening of the lower end surface of the guide tube 8, and the limiting seat 31 is provided with a buckle hole 32 at the position corresponding to the hook 72, and the hook 72 is buckled into the buckle hole 32 to be fixed thereto.
[0027] The safety piece 7 has an "n"-shaped cross-section and is clamped and hingedly installed on the side wall of the hinge arm 4. A limiting column 73 extends from the inner end surface of the safety piece 7 toward the hinge arm 4. Correspondingly, a limiting groove 41 is provided on the side wall of the hinge arm 4, and the limiting column 73 extends into the limiting groove 41 to limit the swing angle of the safety piece 7.
[0028] The hinge arm 4 is provided with a limiting platform 42 . After the safety piece 7 is closed, a limiting area 43 is formed between the hook 72 and the limiting platform 42 , and the limiting seat 31 is clamped and fixed in the limiting area 43 .
[0029] Working principle:
[0030] In the present invention, the hinge arm is connected to the main arm body through a hinge shaft. When the box door is opened or closed, the hinge arm rotates around the hinge shaft, thereby realizing the opening and closing of the box door. Among them, a safety plate is also provided on the hinge arm in this case, which is swing-hinged and installed on the hinge arm and is provided with a buckle groove 71. When the hinge arm leaves the factory, the hinge arm is opened, and the buckle groove on the safety plate is used to clamp on the main arm body to limit the hinge arm to an open state. This design allows the hinge to be in an open state when installed, thereby facilitating the installation of the hinge, the box body and the box door.
[0031] When the hinge is installed, the main arm is fixed to the box body, and then the box door is sleeved on the hinge arm using the opening set on the lower end surface of the guide tube on its back. The guide tube limits the positioning of the box door and the hinge arm in the front and back directions. Then the box door is opened outwards, and the hinge arm is opened outwards using the box door, forcing the safety plate to separate from the main arm. The user can rotate the safety plate, and use the hook 72 on the safety plate to hook with the limit seat 31 on the box door, thereby limiting the up and down displacement between the box door and the hinge arm, and preventing the box door from separating from the hinge arm. This design not only ensures the stable connection of the oven door, but also makes the disassembly and assembly of the oven door easier due to its screw-free design, reducing the difficulty of daily maintenance.
[0032] Furthermore, the limiting platform 42 on the chain arm and the limiting area 43 formed after the safety plate is closed provide additional protection for the stable movement of the door. This design ensures that the limiting seat 31 is fixed in the limiting area, further improving the stability and safety of the structure.
[0033] In summary, the present invention significantly improves the convenience of installation and disassembly between the oven door and the hinge, while ensuring the stability and safety of the oven door, so it can be widely promoted and used.
[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
