DETAILED DESCRIPTION

[0018] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-3 As shown, a lining of a medium frequency furnace comprises a support frame 1, a base 2 with a cavity inside is arranged on the support frame 1, a furnace shell 3 is installed on the base 2, a furnace lining 5 is movably arranged inside the furnace shell 3, and a pushing mechanism 18 for popping up the furnace lining 5 is arranged inside the base 2;

[0020] The pushing mechanism 18 includes a first spring 8 and a support plate 9. The first spring 8 is fixedly arranged inside the base 2. The top end of the first spring 8 is fixedly connected to the lower end of the support plate 9. The upper end of the support plate 9 penetrates into the furnace shell 3 and contacts the bottom surface of the furnace lining 5. A limiting groove 10 is provided on one side of the support plate 9. A limiting component 17 for limiting the support plate 9 is provided inside the base 2.

[0021] When the lining 5 needs to be replaced, the connecting rod 16 is pulled by pulling the pull ring 15 to move the connecting plate 13, thereby pulling the limiting plate 14 out of the limiting groove 10, canceling the limiting of the support plate 9, and pushing the support plate 9 upward by the elastic force of the first spring 8. When the support plate 9 moves upward, the lining 5 is pushed upward, so that people can easily take the lining 5 out of the furnace shell 3 for maintenance or replacement. By setting the second slider 7, the lining 5 is kept stable in the furnace shell 3. When the lining 5 needs to be installed, the second sliders 7 on both sides of the lining 5 are first aligned with the second slide groove 6 and then inserted. At this time, the pull ring 15 is pulled to control the connecting plate 13 and the limiting plate 14 to adjust the position, and the support plate 9 is driven downward by pressing the lining 5 downward. The pull ring 15 is released, and the connecting plate 13 and the limiting plate 14 are pushed to move by the elastic force of the second spring. After the limiting plate 14 is inserted into the limiting groove 10, the support plate 9 is limited.

[0022] like Figure 3 As shown, the limiting assembly 17 includes a second spring, a connecting plate 13 and a limiting plate 14. The second spring is fixedly arranged on one side of the base 2, the other end of the second spring is connected to one side of the connecting plate 13, and one end of the limiting plate 14 is fixedly connected to the other side of the connecting plate 13. When the connecting plate 13 is moved by the elastic force of the second spring, it drives the limiting plate 14 to be inserted into the limiting groove 10 to limit the support plate 9.

[0023] In this embodiment, the support plate 9 can be limited by setting a limit component 17. When the furnace lining 5 is installed, the height of the support plate 9 is restricted. When the furnace lining 5 needs to be taken out, the limit on the support plate 9 is cancelled by using the limit component 17, and the support plate 9 is lifted up by the action of the second spring, thereby lifting up the furnace lining 5, making it easier for people to take out the furnace lining 5.

[0024] like Figure 1 As shown, a first slide groove 11 is provided at the bottom of the base 2 , a first slider 12 is slidably provided in the first slide groove 11 , and the first slider 12 is connected to the lower end of the connecting plate 13 .

[0025] In this embodiment, the first sliding block 12 is provided to increase the stability of the connecting plate 13 when it moves.

[0026] like Figure 1As shown, a connecting rod 16 is provided inside the base 2 , one end of the connecting rod 16 is fixedly connected to one side of the connecting plate 13 , and the other end of the connecting rod 16 passes through the outside of the base 2 and is installed with a pull ring 15 .

[0027] In this embodiment, pulling the pull ring 15 drives the connecting rod 16 , the connecting plate 13 and the limiting plate 14 to move, thereby pulling the limiting plate 14 out of the limiting groove 10 .

[0028] like Figure 1 As shown, the inner wall of the furnace shell 3 is symmetrically provided with second slide grooves 6 , and second sliders 7 are slidably arranged inside the second slide grooves 6 , and one end of the second sliders 7 is connected to the outer wall of the furnace lining 5 .

[0029] In this embodiment, the furnace lining 5 is limited by providing the second sliding block 7 so that the furnace lining 5 is kept stable in the furnace shell 3 .

[0030] Working principle: when the furnace lining 5 needs to be replaced, the connecting rod 16 is pulled by pulling the pull ring 15 to move the connecting plate 13, thereby pulling the limit plate 14 out of the limit groove 10, canceling the limit on the support plate 9, and the elastic force of the first spring 8 pushes the support plate 9 upward. When the support plate 9 moves upward, the furnace lining 5 is pushed upward, making it convenient for people to take out the furnace lining 5 from the furnace shell 3 for maintenance or replacement. When the furnace lining 5 needs to be installed, first align the second sliders 7 on both sides of the furnace lining 5 with the second slide groove 6 and then put it in. At this time, pull the pull ring 15 to control the connecting plate 13 and the limit plate 14 to adjust the position, and drive the support plate 9 to move downward by pressing the furnace lining 5 downward, release the pull ring 15, and push the connecting plate 13 and the limit plate 14 to move by the elastic force of the second spring, and insert the limit plate 14 into the limit groove 10 to limit the support plate 9.
