[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Referring to Figures 1-6 , a special tool for opening and closing the viewing hole door of a furnace chamber, which includes a handle rod 1 and a furnace door 6. A cross beam 2 is fixedly installed at the front end of the handle rod 1. A vertical beam 3 that extends forward and is perpendicular to the cross beam 2 is fixedly installed at the front end of one side of the cross beam 2. A lower beam 4 that extends downward and is perpendicular to the cross beam 2 is fixedly installed at the other end of the cross beam 2. The furnace door 6 includes a hinge platform 7 on one side of the observation port and a hinge column 8 on the other side of the observation port. A sealing door 9 is hinged on one side of the hinge column 8. The sealing door 9 protrudes outward with a locking tooth 10 at the hinge platform 7. A rotating rod 11 is rotatably connected to the middle of the hinge platform 7. The rotating rod 11 is sleeved inside the locking tooth 10. A ball head 12 is fixedly installed at the front end of the rotating rod 11. The ball head 12 is located outside the locking tooth 10. A handle 13 is fixedly installed at the bottom end of the ball head 12.

[0024] A heat insulation sleeve 5 is fixedly installed at the end of the handle rod 1 away from the cross beam 2. The surface of the heat insulation sleeve 5 is rough. The function of the heat insulation sleeve 5 is to isolate heat and avoid scalding hands. By restricting the roughness of the surface of the heat insulation sleeve 5, the friction can be increased to avoid hand slipping.

[0025] The diameter of the ball head 12 is greater than the width of the notch part of the locking tooth 10. With such a setting, when the ball head 12 rotates to be perpendicular to the furnace door 6, at this time, the locking tooth 10 is restricted by the ball head 12 and cannot rotate.

[0026] A lifting ring 14 is arranged on the surface of the sealing door 9. The lifting ring 14 is rotatably connected to the sealing door 9. When the vertical beam 3 is rotated and inserted inside, the lifting ring 14 can assist in opening and closing the sealing door 9, making the operation more convenient.

[0027] A threaded groove 15 is opened at the front end of the rotating rod 11. The ball head 12 is threadedly connected to the rotating rod 11. With such a setting, the ball head 12 can be rotated to make the ball head 12 closer to the sealing door 9, thereby providing a better sealing effect.

[0028] The included angle between the handle 13 and the axis of the hinge platform 7 is greater than ninety degrees. The handle 13 is inclined outward. With such a setting, the gap between the handle 13 and the sealing door 9 can be increased, so that the lower beam 4 can be more conveniently inserted below the handle 13 from the side.

[0029] In use, first place the vertical beam 3 on the side of the handle 13 close to the hinge column 8, apply a lateral force, use the vertical beam 3 to rotate the handle 13 to the outside of the locking teeth 10, and then insert the vertical beam 3 into the inside of the lifting ring 14. By pulling the lifting ring 14, the sealing door 9 can be opened. When it is necessary to close the sealing door 9, bring the lower beam 4 close to the sealing door 9 and push the sealing door 9 to rotate until it is parallel to the furnace door 6. Then, use the lower beam 4 to rotate the handle 13 until it coincides with the locking teeth 10, so that the opening and closing of the sealing door 9 can be conveniently realized. When the ball head 12 is threadedly connected to the rotating rod 11, insert the lower beam 4 laterally between the handle 13 and the furnace door 6. The vertical beam 3 abuts against the protruding part of the locking teeth 10 of the sealing door 9 and takes the vertical beam 3 as the rotation center point. By rotating the handle rod 1, drive the handle 13 to rotate by using the lower beam 4, so that the handle 13 can be driven to rotate around the rotating rod 11, and thus the sealing door 9 and the furnace door 6 can be pressed tightly. Vice versa.

[0030] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
