Referring to fig. 1-5, the present invention provides a technical solution: a sealing structure of a pit annealing furnace comprises an annealing furnace body 1 and an annealing furnace cover 2, wherein the annealing furnace cover 2 is arranged at the upper end of the annealing furnace body 1, a threaded rod 3 is connected onto the annealing furnace cover 2 in a threaded manner, a rotating handle 4 positioned outside the annealing furnace cover 2 is fixedly connected onto one end of the threaded rod 3, a spiral sealing groove 6 is formed in the inner wall of the annealing furnace body 1, and a sealing mechanism is arranged on the annealing furnace cover 2;

when the annealing furnace cover 2 and the annealing furnace body 1 are closed, the sealing mechanism is matched with the sealing groove 6 to seal the annealing furnace body 1, so that the phenomenon that the stability of the internal temperature of the annealing furnace body 1 is influenced by the fact that external gas enters the annealing furnace body 1 is avoided, meanwhile, the phenomenon that high temperature in the annealing furnace body 1 overflows to the outside is avoided, and normal annealing of workpieces is ensured.

Further, the sealing mechanism comprises an annular sealing ring 5, the sealing ring 5 is fixedly connected to one side, close to the annealing furnace body 1, of the annealing furnace cover 2, a spiral through groove 10 is formed in the sealing ring 5, and a sealing gasket 11 matched with the through groove 10 is movably connected inside the through groove 10;

one end of the threaded rod 3 extends into the sealing ring 5, one end of the threaded rod 3 extending into the sealing ring 5 is fixedly connected with a blocking block 7, one end, far away from the threaded rod 3, of the blocking block 7 is fixedly connected with a pushing column 8, a pushing groove 12 which is in a transverse T shape is formed in the pushing column 8, a stress block 13 which is mutually matched with the pushing groove 12 is fixedly connected to the inner side of the sealing gasket 11, and the stress block 13 is connected into the pushing groove 12 in a sliding mode;

the pushing column 8 is conical, the blocking block 7 is cylindrical, and the pushing groove 12 is spirally formed in the pushing column 8.

When the annealing furnace cover 2 and the annealing furnace body 1 need to be sealed, only the annealing furnace cover 2 needs to be closed at the upper end of the annealing furnace body 1, at the moment, the sealing ring 5 enters the annealing furnace body 1, so that the threaded rod 3 is rotated, the rotation of the threaded rod 3 drives the blocking block 7 and the pushing column 8 to rotate simultaneously, and meanwhile, as the threaded rod 3 is in threaded connection with the annealing furnace cover 2, the rotation of the threaded rod 3 enables the blocking block 7 and the pushing column 8 to move downwards simultaneously, so that the diameter of the pushing column 8 is continuously increased, the position of the stress block 13 in the pushing groove 12 is subjected to the change of the diameter of the pushing column 8, so that the sealing gasket 11 is continuously and outwards slid, the sealing gasket 11 is clamped into the sealing groove 6, at the moment, the stress block 13 is attached to the inner wall of the sealing ring 5, so that the blocking block 7 blocks the stress block 13, the sealing gasket 11 is prevented from being separated from the inside of the annealing furnace body 6, and the sealing groove between the annealing furnace body 1 and the annealing furnace cover 2 is realized;

meanwhile, the sealing gasket 11 and the sealing groove 6 are both spiral, so that the sealing between the annealing furnace body 1 and the annealing furnace cover 2 is multi-layer sealing, the gas leakage phenomenon can be effectively avoided, the temperature inside the annealing furnace body 1 is ensured to be in a stable state all the time, and the annealing effect on the workpiece is ensured.

Through all setting up atress piece 13 and promotion groove 12 into horizontal T font, consequently along with promoting the diameter change of post 8, the pulling atress piece 13 that can be better carries out the atress with sealed the pad 11, consequently ensures sealed pad 11 can slide in the inside of logical groove 10, consequently ensures sealed effect.

Further, a high-temperature resistant rubber pad 9 is fixedly connected to the surface of the sealing pad 11;

due to the high-temperature-resistant rubber gasket 9, the gap between the sealing groove 6 and the sealing gasket 11 is reduced according to the elasticity of the sealing groove, and the sealing effect is ensured.

The working principle is as follows: when the annealing furnace cover 2 and the annealing furnace body 1 need to be sealed, only the annealing furnace cover 2 needs to be closed at the upper end of the annealing furnace body 1, at the moment, the sealing ring 5 enters the annealing furnace body 1, the threaded rod 3 is rotated, the rotation of the threaded rod 3 drives the blocking block 7 and the pushing column 8 to rotate simultaneously, and meanwhile, due to the fact that the threaded rod 3 is in threaded connection with the annealing furnace cover 2, the blocking block 7 and the pushing column 8 move downwards simultaneously due to the rotation of the threaded rod 3, and therefore the diameter of the pushing column 8 is increased continuously, the sealing gasket 11 slides outwards continuously due to the fact that the diameter of the pushing column 8 is changed at the position of the stress block 13 inside the pushing groove 12, the sealing gasket 11 is clamped into the sealing groove 6, at the moment, the stress block 13 is attached to the inner wall of the sealing ring 5, the blocking block 7 blocks the stress block 13, the sealing gasket 11 is prevented from being separated from the inside of the annealing furnace body 6, and therefore sealing between the annealing furnace body 1 and the annealing furnace cover 2 is achieved.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
