[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0020] Embodiments of the present utility model:

[0021] Example 1

[0022] A vacuum molybdenum strip furnace includes a box body 1, support frames 2 are symmetrically fixed to the top of the box body 1, and the same furnace body 3 is installed on the two support frames 2 (the furnace body 3 already belongs to the existing technology and will not be described in detail in this application), and a furnace cover 4 is installed at the opening of the furnace body 3. The setting of the furnace cover 4 plays the role of closing the furnace body 3; a handle 16 is installed on the furnace cover 4, and the setting of the handle 16 makes it easy to open or close the furnace cover 4, thereby providing convenience for the staff.

[0023] It should be noted that: a mounting seat 9 is fixed to the outer surface of the furnace body 3, and an "L"-shaped mounting rod 10 is rotatably mounted on the mounting seat 9, and a rotating seat 11 is rotatably mounted on the free end of the mounting rod 10, and the rotating seat 11 is fixedly connected to the outer surface of the furnace cover 4. Through the arrangement of the mounting seat 9, the mounting rod 10 and the rotating seat 11, the furnace cover 4 can be rotated at the position of the rotating shaft of the mounting seat 9, so that the furnace body 3 can be opened or closed.

[0024] The furnace body 3 is provided with a ring-shaped placement groove 15 at the opening thereof, and a ring-shaped sealing ring (not shown in the figure) is installed inside the ring-shaped placement groove 15. The setting of the sealing ring 15 plays a sealing role.

[0025] Example 2

[0026] Although the above embodiment 1 can seal the furnace body 3 so that the molybdenum ribbon furnace can heat the material under a vacuum state, the sealing effect is relatively poor. Therefore, in order to solve the above-mentioned technical problems, improvements are made on the basis of embodiment 1.

[0027] A locking ring 5 is provided at the connection between the furnace body 3 and the furnace cover 4. Specifically, the locking ring 5 includes two semicircular rings 51. A fixing plate 52 is provided at the connection between the two semicircular rings 51. Bolts (not shown in the figure) connected to the semicircular rings 51 are provided on the fixing plate 52. The provision of the two semicircular rings 51 facilitates the installation or removal of the locking ring 5, thereby providing convenience for the staff.

[0028] Several pressing blocks 8 are equidistantly installed on one side of the semicircular ring 51, and several wedge-shaped blocks 7 are equidistantly installed on one side of the furnace cover 4 along the circumferential direction. When the locking ring 5 drives the several pressing blocks 8 to rotate, the inclined surfaces of the several wedge-shaped blocks 7 can be squeezed. Multiple wedge-shaped blocks 7 can squeeze the furnace cover 4, so that the furnace cover 4 can increase the degree of closure with the furnace body 3, increase the sealing, and reduce the phenomenon of air leakage.

[0029] Two drive assemblies are installed on the furnace body 3 along the circumferential direction. The two drive assemblies are respectively connected to the semicircular ring 51. Through the arrangement of the two drive assemblies, the locking ring 5 can be driven.

[0030] Specifically, each driving assembly includes a mounting frame 61 mounted on the outer surface of the furnace body 3, and an electric telescopic rod 62 is rotatably mounted on the mounting frame 61, and a driving seat 63 is rotatably mounted on the telescopic end of the electric telescopic rod 62, and the driving seat 63 is fixed on the outer surface of the semicircular ring 51. When the telescopic end of the electric telescopic rod 62 is extended or shortened, it can drive the locking ring 5 to rotate. During the rotation process, the locking ring 5 can drive the pressing block 8 to rotate, so that the pressing block 8 can squeeze or release the wedge block 7, thereby closing or opening the furnace cover 4.

[0031] A number of mounting grooves 12 are equidistantly provided on each semicircular ring 51, and a rotating shaft 13 is fixed inside the mounting groove 12, and a sliding wheel 14 is rotatably mounted on the rotating shaft 13, and the sliding wheel 14 is in contact with the outer surface of the furnace body 3. Through the setting of the sliding wheel 14, the locking ring 5 can rotate smoothly on the furnace body 3.

[0032] When closing the furnace cover 4, first close the furnace cover 4 at the opening of the furnace body 3, and at the same time open the two electric telescopic rods 62. The telescopic ends of the two electric telescopic rods 62 extend at the same time and push the drive seat 63. The two drive seats 63 can simultaneously drive the locking ring 5 to rotate on the furnace body 3. During the rotation, the locking ring 5 can rotate several pressing blocks 8, so that the pressing blocks 8 can squeeze the inclined surface of the wedge block 7. When multiple wedge blocks 7 are subjected to the extrusion force, they can squeeze the furnace cover 4, thereby improving the degree of closure of the furnace cover 4 and the furnace body 3 and reducing the phenomenon of air leakage in the molybdenum strip furnace.
