[0002] In many aspects of industrial production, heating furnaces play an irreplaceable role and are widely used in fields such as steel smelting, machining, and ceramic firing. As a key component of heating furnaces, the performance of the furnace door directly affects the overall efficiency and operational safety of the furnace. However, many problems have been exposed in the actual use of heating furnace doors on the market.

[0003] Existing heating furnace doors generally adopt simple sealing structures, which make it difficult to form an effective seal between the door and the furnace body. In high-temperature operating environments, a large amount of heat inside the furnace is lost to the surrounding environment through the gaps in the door. This not only causes a huge waste of energy and increases the production and operating costs of enterprises, but also creates high-temperature radiation in the working area, posing a serious threat to the personal safety of on-site operators and easily causing burn accidents. Therefore, this application designs a door structure for heating furnaces to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a door structure for a heating furnace, comprising a furnace body 1. A hinge 3 is bolted to one side wall of the furnace body 1, facilitating smooth and stable opening and closing of a cabinet door 2, while ensuring precise fit between the door and the furnace body 1 when closed. A cabinet door 2 is hinged to the hinge 3, allowing convenient operation and maintenance of the furnace interior. A latch mounting plate 4 is fixed to the side wall of the cabinet door 2, enhancing the stability of the locking structure and ensuring secure operation during heating. The cabinet door 2 will not open accidentally during the operation of the hot furnace; a limit block is fixed on the locking mounting plate 4, and a locking component is installed on one side wall of the furnace body 1. The cabinet door 2 is provided with a threaded groove, and a pushing component is threadedly connected in the threaded groove. The pushing component facilitates precise control of the position of the heat insulation plate 5, thereby effectively adjusting the heat insulation performance of the door. One end of the pushing component is provided with the heat insulation plate 5, which effectively improves the heat insulation performance of the heating furnace, reduces energy consumption, and prevents heat from overflowing and causing injury to the operator.

[0020] In this utility model, the propulsion component includes a transmission threaded rod 8 disposed in a threaded groove. One end of the transmission threaded rod 8 is fixedly connected to an adjustment knob 6, and the other end of the transmission threaded rod 8 is sleeved with an abutment heat insulation plate 5. The adjustment knob 6 allows the operator to easily and accurately control the abutment degree between the abutment heat insulation plate 5 and the furnace body 1, improving the adjustability of the door's heat insulation effect. Four mounting blocks are symmetrically arranged on the side wall of the abutment heat insulation plate 5, and four guide rods 7 are provided on the four mounting blocks. Corresponding guide holes are opened on the other side wall of the cabinet door 2, and the guide rods 7 are slidably connected in the guide holes. The guide rods 7 facilitate the stability of the movement of the abutment heat insulation plate 5 when it approaches or moves away from the furnace body 1, ensuring that the heat insulation plate and the furnace body 1 are tightly fitted. The locking component includes a mounting block disposed on one side wall of the furnace body 1. The cabinet door 2 is mounted on a rotatable locking plate 10. A locking block 9 is mounted on the locking plate 10, with one end of the block 9 movably connected to the other end of the locking plate 10 via a pin. This locking mechanism provides a reliable mechanical locking mechanism, ensuring that the cabinet door 2 will not be accidentally opened when closed. An abutment rod 11 is screwed into the middle of the locking plate 10, with a handle 12 vertically welded to the other end. The abutment rod 11 provides additional locking adjustment, enhancing the reliability of locking the cabinet door 2. An abutment groove is provided on the locking plate 10. When the locking plate 10 is closed, the abutment groove abuts against a limiting block. The locking plate 10 facilitates convenient locking and unlocking of the cabinet door 2, and the cooperation between the abutment groove and the limiting block improves the stability of the locking structure.

[0021] Working Principle: In the use of this utility model, during daily use or maintenance of the heating furnace, it is necessary to open or close the cabinet door 2. The cabinet door 2 is connected to the furnace body 1 via a hinge 3. The operator only needs to manually push the cabinet door 2 to rotate it around the pivot of the hinge 3, easily completing the opening and closing action, facilitating entry into the furnace for work. When the cabinet door 2 is closed, the locking plate 10 installed on the side wall of the furnace body 1 begins to function. The operator rotates the locking plate 10, causing the locking block 9, which is movably connected to the locking plate 10 via a pin, to rotate. When block 9 rotates to correspond with the position of the limiting block on the latch mounting plate 4 on the side wall of cabinet door 2, block 9 will engage with the limiting block area, initially locking cabinet door 2. Furthermore, the locking connecting plate 10 has an abutment groove. During the closing process of the locking connecting plate 10, the abutment groove will tightly abut against the limiting block, further enhancing the stability of the lock. To make the locking effect more reliable, the operator can also rotate the abutment rod 11 by rotating the handle 12. Since the abutment rod 11 is screwed into the middle of the locking connecting plate 10, its extension length will change during rotation, making the abutment rod... 11. Tighten cabinet door 2 to prevent it from loosening during furnace operation. After cabinet door 2 is closed and locked, to reduce heat loss and improve energy efficiency, the position of the heat insulation plate 5 needs to be adjusted. The operator rotates the adjustment knob 6, which drives the transmission threaded rod 8 fixedly connected to the adjustment knob 6 to rotate. Because the transmission threaded rod 8 is threaded into the threaded groove of cabinet door 2, it will move linearly along the thread direction when rotated. Since the other end of the transmission threaded rod 8 is sleeved and abuts the heat insulation plate 5, its linear movement... During operation, the heat insulation plate 5 will move synchronously. A guide rod 7 is installed on the side wall of the heat insulation plate 5. The guide rod 7 is slidably connected in the guide hole of the cabinet door 2. This ensures the smooth movement of the heat insulation plate 5 and prevents deviation. When the heat insulation plate 5 moves to a tight contact with the edge of the furnace body 1 opening, it can effectively block the heat loss in the furnace, reduce energy consumption, and prevent heat overflow from causing injury to the operator. Finally, when it is necessary to open the cabinet door 2, the above steps are reversed. This concludes the use of the door structure for the heating furnace.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
