Description

Technical Field

[0001] This utility model relates to the technical field of furnace door hinge devices, specifically a microwave hot air furnace door hinge device. Background Technology

[0002] A microwave hot air furnace is a composite industrial equipment that combines microwave heating technology with a traditional hot air circulation system. Its core feature is that it uses microwave energy to heat the gas medium quickly and evenly, while achieving efficient heat transfer through a heat exchange system. The furnace door hinge structure is the connection structure between the furnace door and the furnace body, and the furnace door is opened and closed through the hinge structure.

[0003] For example, Chinese patent CN222143708U discloses a vacuum furnace door hinge device, which belongs to the field of vacuum furnace equipment technology. It includes a furnace base and a furnace door. A C-shaped hinge seat is installed on one side of the furnace base, and a hinge shaft is rotatably connected inside the hinge seat. Two sets of support mechanisms are installed at the bottom of the connecting plate frame. The support mechanism includes a support frame, a lifting frame, a lead screw, a lead screw nut, a driven bevel gear, a driving bevel gear, and an adjusting component. The bottom area of ​​the lifting frame is equipped with moving wheels. This device, through the coordination of adjusting components, bevel gear sets, lead screw nuts, and other accessories in the support mechanism, enables the extension and retraction between the support frame and the lifting frame. This allows the moving wheels to effectively contact the ground, and part of the weight of the furnace door is effectively supported by the support mechanism and the moving wheels. Simultaneously, the moving wheels roll as the furnace door opens, ensuring smooth opening, reducing the load on the hinge seat and hinge bearings, increasing the service life of the furnace door hinge, and improving safety. However, traditional hot air furnace doors have a large overall structural mass, requiring slow and controlled opening and closing with considerable force, significantly increasing the difficulty of opening and closing the furnace door. Therefore, this microwave hot air furnace door hinge device is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides the following technical solution: a microwave hot air furnace door hinge device, comprising:

[0023] In this embodiment, a notch is provided on one side of the outer surface of the hinge fixing seat 1. A hinge fixing piece 21 is fixedly installed inside the hinge fixing seat 1 at the notch. A hinge connecting rod 2 is provided on one side of the hinge fixing seat 1, and the bottom end of the hinge connecting rod 2 is movably connected to one end of the hinge fixing piece 21. A concave pulley 4 is fixedly installed on the outer surface of the hinge fixing seat 1. A second rivet 41 is inserted into one side of the outer surface of the hinge fixing seat 1, and one end of the second rivet 41 passes through one side of the outer surface of the hinge fixing seat 1 and is inserted into the interior of the concave pulley 4. The hinge movable piece 3 slides down along the concave pulley 4. When it slides to the notch position, the furnace door is fully open.

One end of the hinge movable piece 3 is movably connected to the outer surface of the hinge link 2 via the pin. The oven hinge link 2 is fixed to the oven door shell, and the hinge fixing piece 21 is fixed to the oven shell. The oven door shell drives the hinge link 2 to open.

[0025] In this embodiment, the hinge movable piece 3 is installed at the inner bottom of the hinge fixed base 1, and the hinge movable piece 3 is located on one side of the hinge fixed piece 21. One end of the hinge fixed piece 21 passes through the notch and is connected to the outer surface of the hinge link 2.

[0026] The hinge fixing seat 1 has a bushing 32 installed inside above the concave pulley 4. A first rivet 33 is inserted into one side of the outer surface of the hinge fixing seat 1, and one end of the first rivet 33 passes through the outer surface of one side of the hinge fixing seat 1 and is inserted into the first rivet 33. A spring 31 is provided on the other side of the hinge fixing seat 1. Hooks are integrally connected to both ends of the spring 31, and the hook at the top of the spring 31 is sleeved on the outer surface of the bushing 32. During the closing process, the stretched spring 31 will provide an upward pulling force, reducing the force required to close the furnace door and facilitating the opening and closing of the hot air furnace door.

[0027] It should also be noted in this embodiment that a notch is provided on the outer surface of the other end of the hinge movable piece 3, and the bottom hook of the spring 31 is sleeved in the notch. During the downward pulling process, one end of the hinge movable piece 21 will stretch one end of the spring 31, and the pulling force of the spring 31 will hold the furnace door, which can reduce the support of the furnace door during the opening process.
