[0002] A vacuum heat treatment furnace is a heating device used for heat processing or treatment of workpieces.

[0003] For example, the utility model patent with announcement number CN207243943U discloses a vacuum heat treatment furnace, including a vacuum pump and an outer casing. The rear side of the outer casing is connected to the vacuum pump through pipes and connectors. The front side of the outer casing is provided with a front panel and a front door pivotally connected thereto. The upper side of the inner cavity of the outer casing corresponding to the front panel is provided with a horizontally placed middle partition. The inner cavity of the outer casing above the middle partition is provided with a vacuum inner casing that communicates with the vacuum pump. The inner furnace chamber is fitted inside the vacuum inner casing. A sealing plate is connected to the rear side of the front door to cover the open end of the vacuum inner casing. A silicone sealing ring is also installed around the periphery of the sealing plate. An end cap for sealing the entire open end of the inner furnace chamber is also installed in the middle of the sealing plate. A bore door seal that extends into the open end of the inner furnace chamber is also installed in the center of the end cap.

[0004] However, this utility model requires manual opening of the front door during use, which increases the labor intensity of workers and results in poor performance. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A vacuum heat treatment device includes a support base, on which a vacuum heat treatment furnace is mounted. One end of the vacuum heat treatment furnace has a front door. A pair of support frames are fixedly connected to one surface of the vacuum heat treatment furnace. A connecting frame is hinged within the pair of support frames. One end of the connecting frame is fixedly connected to the front door, and the other end of the connecting frame is hinged to a movable plate. A fixed plate is fixedly connected to one surface of the vacuum heat treatment furnace. A rotating plate is hinged to one end of the fixed plate. A threaded rod is rotatably connected to one surface of the rotating plate, and a geared motor is fixedly connected to the other surface of the rotating plate. One end of the threaded rod passes through the rotating plate and is fixedly connected to the drive end of the geared motor. The threaded rod is threadedly connected within the movable plate.

[0007] Preferably, a limiting top is fixedly connected to one surface of the rotating plate.

[0008] Preferably, the threaded rod has self-locking properties.

[0009] Beneficial effects:

[0010] This utility model provides a vacuum heat treatment device, which has the following beneficial effects:

[0011] Starting the geared motor can drive the threaded rod to rotate. The rotation of the threaded rod can drive the movable plate to move closer to the rotating plate. The movement of the movable plate to the rotating plate can drive the connecting frame to rotate. The rotation of the connecting frame can open the front door, reducing the labor intensity of the workers. Attached Figure Description
