The height level is observed through a spirit level. If it does not meet the requirement, the furnace bed support columns need to be taken out for processing and adjusting the length, and then readjusted after reinstallation until it is completely horizontal. This process is time-consuming and laborious, so it needs to be improved. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0026] As Figures 1 to 6 shown, the present utility model provides a structure for adjusting the height of the furnace bed of the heating chamber of a vacuum furnace, including:

[0027] Vacuum furnace 1, the inner surface of the vacuum furnace 1 is movably connected with mounting blocks 2. The number of the mounting blocks 2 is two. A cylinder 3 is fixedly connected between the two mounting blocks 2. The inner surface of the cylinder 3 is movably connected with a heating chamber 4. The inside of the heating chamber 4 is movably connected with a furnace bed body 5. The bottom of the inner cavity of the vacuum furnace 1 is fixedly connected with a support 6;

[0028] Adjusting mechanism, the adjusting mechanism is arranged on the top of the support 6;

[0029] Among them, the adjusting mechanism includes a fixed seat 7. The bottom of the fixed seat 7 is fixedly connected with the top of the support 6. A sleeve 8 is threadedly connected to the inner surface of the fixed seat 7. The inside of the top end of the sleeve 8 is movably connected with a furnace bed support column 9. The top of the furnace bed support column 9 sequentially penetrates through the cylinder 3 and the heating chamber 4 and extends into the inside of the heating chamber 4. A limiting block 10 is fixedly connected to the outer side of the furnace bed support column 9. The outer surface of the limiting block 10 is movably connected with the inner surfaces of the cylinder 3 and the heating chamber 4 respectively. A round shaft 11 is movably sleeved inside the top end of the furnace bed support column 9. A furnace bed partition bar 12 is fixedly sleeved on the outer surface of the round shaft 11. The outer surface of the furnace bed partition bar 12 is movably connected with the inner surface of the furnace bed support column 9. The top of the furnace bed partition bar 12 is movably connected with the bottom of the furnace bed body 5. Rotating the sleeve 8 drives the furnace bed support column 9 to move upward to adjust the height level of the furnace bed body 5.

[0030] When the sleeve 8 moves upward, it will drive the furnace bed support column 9 to move upward, and then drive the furnace bed body 5 to move upward. At the same time, under the limiting effect of the limiting block 10, the stability of the furnace bed partition bar 12 is ensured during the upward movement of the furnace bed support column 9, thereby avoiding the rotation and wear of the furnace bed partition bar 12.

[0031] Among them, fixed blocks 13 are fixedly connected to both sides of the inner cavity of the vacuum furnace 1 and are located behind the mounting blocks 2. Threaded rods 14 are threadedly connected to the inside of both the fixed blocks 13 and the mounting blocks 2.

[0032] With such a design, the mounting blocks 2 and the fixed blocks 13 are connected and fixed by the threaded rods 14, and thus the cylinder 3 is in a fixed state.

[0033] Among them, a connecting block 15 is fixedly connected to the outer surface of the cylinder 3. A round wheel 16 is movably installed inside the other end of the connecting block 15. The outer surface of the round wheel 16 is movably connected with the inner surface of the vacuum furnace 1.

[0034] The design of the connecting block 15 and the round wheel 16 can drive the overall movement of the cylinder 3.

[0035] Among them, a limiting rod 17 is fixedly installed inside the heating chamber 4. The outer surface of the limiting rod 17 is movably connected with the outer surface of the furnace bed body 5.

[0036] The design of the limiting rod 17 plays a role in limiting the furnace bed body 5.

[0037] Among them, a side cavity 18 is provided inside the front of the hearth body 5. A spring 19 is fixedly connected inside the side cavity 18. The number of springs 19 is two. The other ends of the two springs 19 are both fixedly connected with clamping blocks 20. The number of clamping blocks 20 is two. The outer surfaces of the two clamping blocks 20 are both movably connected with the inner surface of the side cavity 18. The two clamping blocks 20 move away from each other to clamp and fix the spirit level.

[0038] Pulling the two clamping blocks 20 to move away from each other will cause the two clamping blocks 20 to squeeze the two springs 19 to move away from each other. As the distance between the two clamping blocks 20 increases, it is convenient to clamp and fix the spirit level.

[0039] Among them, the number of hearth partition bars 12 is three. The sizes of the three hearth partition bars 12 are the same. The appearances of the three hearth partition bars 12 are all rectangular.

[0040] The design of the three hearth partition bars 12 has a better supporting effect on the hearth body 5.

[0041] Among them, the number of hearth support columns 9 is three. The outer surfaces of the three hearth support columns 9 are all smooth.

[0042] The design of the smooth outer surfaces of the three hearth support columns 9 facilitates the smoother movement of the three hearth support columns 9 inside the cylinder 3 and the heating chamber 4.

[0043] The working principle and usage process of the present utility model:

[0044] When adjusting the height level of the hearth body 5, by rotating the three sleeves 8 to move upward, the three hearth support columns 9 will be driven to move upward, and then the hearth body 5 will be driven to move upward. With the cooperation of the three sleeves 8 and the three hearth support columns 9, the purpose of facilitating the adjustment of the height level of the hearth body 5 is achieved, solving the complexity of repeatedly assembling and adjusting the height. At the same time, under the limiting action of the limiting block 10, it is avoided that the rotation of the sleeve 8 drives the hearth support column 9 and the hearth partition bar 12 to rotate, eliminating the situation of wear caused by the rotation of the hearth partition bar 12, and improving the service life of the hearth partition bar 12.

[0045] When measuring the height level of the hearth body 5, generally, a spirit level is manually held to measure the height level of the hearth body 5. However, there are errors in manually holding the spirit level for measurement. In order to reduce the measurement error, at this time, pulling the two clamping blocks 20 to move away from each other will squeeze the two springs 19. When the distance between the two clamping blocks 20 increases, the spirit level is placed between the two clamping blocks 20, and then the clamping blocks 20 are released. Under the action of the elastic recovery of the two springs 19, the two clamping blocks 20 are driven to move towards each other to clamp and fix the spirit level, thereby reducing the measurement error.
