The furnace body 1 is provided with a furnace mouth 2; the door body 3 is provided on the furnace mouth 2, and the door body 3 is rotatably connected to the furnace body 1. The door body 3 includes a first sealing plate 31, a second sealing plate 32, a rotating structure 33 and an elastic structure 34. The first sealing plate 31 is fixedly connected to the second sealing plate 32, the rotating structure 33 passes through the first sealing plate 31, and the elastic structure 34 passes through the second sealing plate 32. One end of the rotating structure 33 passing through the first sealing plate 31 is fixedly connected to one end of the elastic structure 34 passing through the second sealing plate 32. The rotating structure 33 is rotated so that the elastic structure 34 rotates to the inner edge of the furnace mouth 2 and is pressed against a side of the inner edge close to the interior of the furnace body 1. When the door body 3 is impacted by gas, the elastic structure 34 is first squeezed, so that the door body 3 will not separate upward from the furnace mouth 2 to form a gap, thereby effectively preventing heat from escaping from the furnace body 1. By setting a rotating structure 33, the position of the elastic structure 34 is controlled; by setting the elastic structure 34, the elastic structure 34 is squeezed and abutted against the inner edge of the furnace mouth 2. When the door body 3 is impacted by gas, the elastic structure 34 is squeezed first, thereby maintaining a close fit between the door body 3 and the furnace mouth 2, effectively preventing the heat in the furnace body 1 from escaping; the ingenious combination of the rotating structure 33 and the elastic structure 34 enables the door body 3 to remain stable when impacted by high-pressure gas, and will not separate from the furnace mouth 2 to form a gap.

[0031] As a preferred embodiment of the present invention, it may also have the following additional technical features: the rotating structure 33 includes a first rotating rod 331 and a rotating disk 332. One end of the first rotating rod 331 is fixedly connected to the rotating disk 332. The first rotating rod 331 passes through the first sealing plate 31. A slide groove 3312 is provided in the first rotating rod 331. The elastic structure 34 is fixedly connected to the slide groove 3312. When the rotating disk 332 is rotated, the first rotating rod 331 drives the elastic structure 34 to rotate. In this embodiment, the rotating disk 332 is made of a heat-insulating material.

[0032] As a preferred embodiment of the present invention, it may also have the following additional technical features: the elastic structure 34 includes a first elastic member 341, a second rotating rod 342, a connecting rod 343, a support member 344, a second elastic member 345 and a support block 346, one end of the first elastic member 341 is fixedly connected to the second rotating rod 342, the end of the second rotating rod 342 away from the first elastic member 341 is fixedly connected to the connecting rod 343, the second rotating rod 342 is vertically arranged to the connecting rod 343, the end of the connecting rod 343 away from the second rotating rod 342 is fixedly connected to the support member 344, the second elastic member 345 is arranged inside the support member 344, and a support block 346 is provided on the second elastic member 345, the support block 346 can abut against the inner edge of the furnace mouth 2, and the end of the first elastic member 341 away from the second rotating rod 342 is fixedly connected to the slide groove 3312. By rotating the rotating disk 332, the first rotating rod 331 drives the second rotating rod 342 to rotate, causing the connecting rod 343 to rotate, causing the support member 344 and the support block 346 to rotate toward the inner edge of the furnace opening 2 to squeeze. When the door body 3 is impacted by the high-pressure gas, the second elastic member 345 prevents the door body 3 from separating outward from the furnace opening 2 to form a gap, effectively preventing heat from escaping from the furnace body 1. In this embodiment, the first elastic member 341 and the second elastic member 345 are both configured as springs.

[0033] As a preferred embodiment of the present invention, it may also have the following additional technical features: a pressure release port 311 is opened in the first sealing plate 31, the pressure release port 311 passes through the first sealing plate 31, a first through hole 3311 is opened on the first rotating rod 331, the first through hole 3311 is connected with the slide groove 3312 and the pressure release port 311, and is used to relieve the pressure of the heating furnace.

[0034] As a preferred embodiment of the present invention, it may also have the following additional technical features: an air passage 3421 is defined within the second rotating rod 342, and second through holes 3422 are defined on both sides of the second rotating rod 342, communicating with the air passage 3421. When the gas pressure within the furnace body 1 is too high, the high-pressure gas passes through the air passage 3421 within the second rotating rod 342, driving the second rotating rod 342 to slide upward within the slide groove 3312. At this time, the second through holes 3422 on both sides of the second rotating rod 342 communicate with the first through hole 3311, allowing the high-pressure gas to be discharged from the furnace body 1 through the pressure release port 311, thereby preventing the heating furnace from exploding due to excessive pressure within the furnace body 1.

[0035] See also Figure 6-Figure 7As a preferred embodiment of the present utility model, it may also have the following additional technical features: a handle 4 is provided on the door body 3, and the handle 4 includes a connecting member 41, a first connecting handle 42, a connecting sleeve 43, and a gripping member 44.

The first connecting handle 42 is fixedly connected to the connecting member 41. The end of the first connecting handle 42 away from the connecting member 41 is detachably connected to the connecting sleeve 43. The end of the connecting sleeve 43 away from the first connecting handle 42 is detachably connected to the gripping member 44. In this embodiment, the first connecting handle 42, the connecting sleeve 43, and the gripping member 44 are all made of heat-insulating material.

[0036] As a preferred embodiment of the present invention, it may also have the following additional technical features: a baffle plate 431 is provided inside the connecting sleeve 43, which divides the connecting sleeve 43 into a first cavity 432 and a second cavity 433. The two separated cavities each assume different functions or mechanical effects, making the overall structure more sturdy and durable. The end of the first connecting handle 42 away from the connecting member 41 is connected to the first cavity 432. The first connecting handle 42 and the baffle plate 431 are connected and fixed by a locking member, and the handgrip 44 is threadedly connected to the second cavity 433. When the handgrip 44 needs to be replaced or the interior needs to be cleaned, it can be quickly disassembled by simply rotating the handgrip 44. At the same time, the design of the baffle plate 431 can slow down the heat conduction process to a certain extent.

[0037] As a preferred embodiment of the present invention, it may also have the following additional technical features: the grip 44 includes a second connecting handle 441, a fixing rod 442, and a handle 443. The second connecting handle 441 is fixedly connected to the handle 443. One end of the fixing rod 442 is embedded and fixed in the second connecting handle 441, and the other end of the fixing rod 442 is embedded and fixed in the handle 443. The second connecting handle 441 is threadedly connected to the second cavity 433. This forms a tight whole between the second connecting handle 441, the fixing rod 442, and the handle 443, greatly improving the structural strength of the entire grip 44 and reducing the heat conduction path to a certain extent.

[0038] As a preferred embodiment of the present invention, it may also have the following additional technical features: an elastic protrusion 434 is fixedly mounted on the wall of the first cavity 432, and a groove is defined within the first connecting handle 42, with the elastic protrusion 434 corresponding to the groove.

[0039] As a preferred embodiment of the present invention, it may also have the following additional technical features: a plurality of anti-slip structures 4431 are provided on the handle 443. Specifically, in this embodiment, the anti-slip structures 4431 are provided as anti-slip grooves for improving the anti-slip performance of the handle 443.

[0040] The working principle of the aluminum rod heating furnace of this embodiment is as follows: the door body 3 is covered on the furnace opening 2 of the furnace body 1 by the handle 4. At this time, the first sealing plate 31 covers the top of the furnace opening 2, and the second sealing plate 32 is sealed and connected to the inside of the furnace opening 2. Then, the rotating disk 332 is rotated. At this time, the first rotating rod 331 drives the second rotating rod 342 to rotate, causing the connecting rod 343 to rotate, so that the support member 344 and the support block 346 rotate to the inner edge of the furnace opening 2 for squeezing. When the door body 3 is impacted by high-pressure gas, the door body 3 will not separate from the furnace opening 2 outward to form a gap due to the restriction of the second elastic member 345. When the gas pressure inside the furnace body 1 is too high, the high-pressure gas passes through the air channel 3421 inside the second rotating rod 342, driving the second rotating rod 342 to slide upward inside the slide groove 3312. At this time, the second through holes 3422 on both sides of the second rotating rod 342 are connected to the first through hole 3311, allowing the high-pressure gas to be discharged from the furnace body 1 through the pressure release port 311. When the heating furnace completes heating, the rotating disk 332 is rotated to separate the supporting member 344 and the supporting block 346 from the inner edge of the furnace opening 2 . At this time, the handle 443 is held to open the door 3 .

[0041] The aluminum rod heating furnace of this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements. In this embodiment, the aluminum rod heating furnace can effectively prevent heat from escaping during the heating process, ensure the heat inside the furnace body 1, and effectively improve the heating efficiency.
