[0002] High-temperature sealed heat treatment equipment is specialized equipment used for heat treatment of materials (especially metallic materials). It is primarily used to improve the mechanical properties, hardness, wear resistance, and corrosion resistance of materials through high-temperature treatment. This type of equipment has a sealing function, allowing heat treatment to be performed under specific atmospheric conditions (such as a protective atmosphere or vacuum environment) to prevent undesirable reactions between the material and oxygen or other gases in the outside air.

[0003] Existing high-temperature sealed heat treatment equipment has safety hazards due to the high internal temperature. When the equipment door is opened or closed, the high-temperature metal inside may spark when it cools down, which could easily lead to accidents. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a high-temperature sealed heat treatment device, which aims to improve the problem that the opening and closing doors of existing high-temperature sealed heat treatment devices lack safety measures and pose safety hazards.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-temperature sealed heat treatment device includes a housing. A first fixing ring is fixedly connected to the upper inner wall of the housing. A rotating shaft is rotatably connected to the inner wall of the first fixing ring. A handle is fixedly connected to the right outer wall of the rotating shaft. A first bevel gear is fixedly connected to the left outer wall of the handle. A second bevel gear is meshed with the outer wall of the first bevel gear.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a high-temperature sealed heat treatment device, including a shell 1. A first fixing ring 2 is fixedly connected to the upper inner wall of the shell 1. A rotating shaft 3 is rotatably connected to the inner wall of the first fixing ring 2. A handle 4 is fixedly connected to the right outer wall of the rotating shaft 3. A first bevel gear 5 is fixedly connected to the left outer wall of the handle 4. A second bevel gear 6 is meshed with the outer wall of the first bevel gear 5. A fixing shaft 7 is fixedly connected to the inner wall of the second bevel gear 6. A second fixing ring 8 is rotatably connected to the middle outer wall of the fixing shaft 7. A toothed wheel 9 is fixedly connected to the front outer wall of the fixing shaft 7. A rack 10 is meshed with the outer wall of the toothed wheel 9. A cabinet door 11 is fixedly connected to the front outer wall of the rack 10. A ratchet 12 is fixedly connected to the middle outer wall of the rotating shaft 3. A ratchet tooth 13 is meshed with the outer wall of the ratchet 12. A wrench 14 is fixedly connected to the inner wall of the ratchet tooth 13. A connecting assembly is provided on the lower inner wall of the shell 1. The connecting assembly is used to connect the shell 1 and the first connecting rod 17.

[0024] Specifically, rotating the handle 4 causes the rotating shaft 3 to rotate, which in turn causes the first bevel gear 5 to rotate, which in turn causes the second bevel gear 6 to rotate, which in turn causes the fixed shaft 7 to rotate, which in turn causes the toothed gear 9 to rotate, which in turn causes the rack 10 to slide, which in turn causes the cabinet door 11 to slide, thus keeping the operator away from the cabinet door 11 when opening the door and improving safety.

[0025] Reference Figure 1 and Figure 3The connecting assembly includes a first connecting shell 15, the upper surface of which is fixedly connected to the lower inner wall of the outer shell 1, and a first connecting shaft 16 slidably connected to the inner wall of the first connecting shell 15; a first connecting rod 17 is rotatably connected to the outer wall of the first connecting shaft 16, and a second connecting rod 18 is provided on the outer wall of the first connecting rod 17; a second connecting shaft 19 is rotatably connected to the inner wall of the second connecting rod 18, and a second connecting shell 20 is slidably connected to the outer wall of the second connecting shaft 19; a third connecting shaft 21 is fixedly connected to the inner wall of the second connecting shell 20, and a hydraulic rod 22 is rotatably connected to the outer wall of the third connecting shaft 21; the output end of the hydraulic rod 22 is rotatably connected to the outer wall of the first connecting shaft 16; a base plate 23 is fixedly connected to the lower surface of the second connecting shell 20; and several casters 24 are fixedly connected to the lower surface of the base plate 23.

[0026] Specifically, when the hydraulic rod 22 is activated, the output end of the hydraulic rod 22 drives the first connecting shaft 16 to slide. The sliding of the first connecting shaft 16 drives the first connecting rod 17 to rotate. The rotation of the first connecting rod 17 drives the second connecting rod 18 to rotate. The rotation of the second connecting rod 18 drives the second connecting shaft 19 to slide. The sliding of the second connecting shaft 19 and the first connecting shaft 16 causes the first connecting shell 15 to rise and fall. The rise and fall of the first connecting shell 15 drives the outer shell 1 to rise and fall, thereby causing the caster wheel 24 to contact or leave the ground, realizing the movement and fixation of the equipment.

[0027] Reference Figure 1 and Figure 2 The upper surface of the second fixing ring 8 is fixedly connected to the upper inner wall of the outer shell 1, the middle outer wall of the rack 10 is set on the front inner wall of the outer shell 1, and the rear outer wall of the cabinet door 11 is slidably connected to the front outer wall of the outer shell 1.

[0028] Specifically, the second retaining ring 8 is used to support the retaining shaft 7, and the rack 10 slides inside the housing 1.

[0029] Working Principle: When using this device, rotating the handle 4 causes the outer wall shaft 3 to rotate, which in turn drives the first bevel gear 5 on the outer wall. The first bevel gear 5 then drives the second bevel gear 6 on the outer wall, which in turn drives the inner wall fixed shaft 7. The fixed shaft 7 then drives the outer wall gear 9, which in turn drives the outer wall rack 10. The rack 10 sliding causes the cabinet door 11 on the outer wall to slide, allowing the operator to move away from the cabinet door 11 when opening it, improving safety. The ratchet 12 and ratchet 13 ensure that the cabinet door 11 can only be closed in one direction. When the wrench 14 is pulled, the ratchet 13 moves away from the ratchet 12, allowing the cabinet door 11 to open, further improving safety. The hydraulic rod 22 on the outer wall of the third connecting shaft 21 is moved. The output end of the hydraulic rod 22 drives the first connecting shaft 16 to slide. When the first connecting shaft 16 slides, it drives the first connecting rod 17 on the outer wall to rotate. When the first connecting rod 17 rotates, it drives the second connecting rod 18 on the outer wall to rotate. When the second connecting rod 18 rotates, it drives the second connecting shaft 19 on the inner wall to slide. When the second connecting shaft 19 and the first connecting shaft 16 slide, the first connecting shell 15 will rise and fall. When the first connecting shell 15 rises and falls, it will drive the outer shell 1 on the upper surface to rise and fall, thereby making the caster wheel 24 contact or leave the ground, which is convenient for moving and fixing the equipment. This not only keeps the operator away from the cabinet door 11 when opening and closing the door, improving safety, but also makes it easier to adjust the equipment position and optimize the workshop layout.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
