[0007] As a further improvement of the utility model, the locking assembly includes a connecting seat arranged on the outside of the vacuum furnace body and a clamping block arranged on the outside of the furnace door. A rotating rod that cooperates with the clamping block is hinged on the connecting seat, and a locking handle is fixedly connected to one end of the rotating rod.

[0008] As a further improvement of the utility model, one end of the rotating rod is hinged to the connecting seat by a bolt, and the contact surface between the locking handle and the clamping block is provided with a rubber ring sleeved on the outside of the rotating rod.

[0009] As a further improvement of the present invention, a bearing seat rotatably connected to the screw rod is fixedly connected to the top of the vacuum furnace body.

[0010] As a further improvement of the utility model, the surface of the screw rod is provided with an external thread, the threaded slide is provided with a thread groove for the screw rod to pass through, and the threaded slide is provided with an internal thread matching the external thread at the thread groove.

[0011] As a further improvement of the utility model, a guide slider is fixedly connected to the bottom of the threaded slide seat, and a guide slide groove for the guide slider to slide is provided on the top wall of the vacuum furnace body.

[0012] As a further improvement of the utility model, the movable plate is rotatably connected to the furnace door via a rotating shaft.

[0013] The beneficial effects of the utility model are as follows: the utility model realizes the connection between the furnace door and the vacuum furnace body through multiple locking components.
