Description

Technical Field

[0001] This utility model relates to the field of electrothermal treatment tooling technology, and in particular to a circulating air uniform circulation mechanism for an induction cooker. Background Technology

[0002] A furnace loading fixture base refers to equipment used to fix and support workpieces during heat treatment. Its main function is to ensure the stability of the workpieces during heat treatment, avoiding deformation or damage, thereby ensuring the quality and precision of the workpieces. It includes a bottom mesh tray and pallets: small holes are opened at the four corners of the bottom mesh tray to install columns, and a No. 1 spacer tube is sleeved on the outside of the columns between the pallets. This design can be used in pit furnaces and multi-purpose furnaces, reducing the types of fixtures and the number of parts, and facilitating management and maintenance; single-layer bracket design: considering the expansion of the workpieces and the stability of long-term use, the single-layer bracket design usually reserves appropriate deformation space between layers to ensure the stability and safety of stacking.

[0003] Existing patent CN215002952U discloses a pit-type resistance furnace fixture, including a base, multiple support columns, the lower ends of which are respectively connected to the base at its edge; an intermediate shelf, disposed above the base and connected to the middle of the support columns; and a column passing through the intermediate shelf, its lower end connected to the base at its interior. This invention addresses the issue that when workpieces are heated and processed in the pit furnace, their range of motion is controlled by the intermediate shelf because each workpiece passes through the placement holes of the intermediate shelf. The fixture is designed to prevent friction and collision between components, thus avoiding scratches on the workpiece surface and improving the workpiece qualification rate. A shelf is installed below the intermediate shelf, providing excellent support and mitigating thermal deformation. Lifting rings allow for simultaneous loading of workpieces into the fixture, enabling the use of an overhead crane to complete the quenching and tempering processes. The appropriate number of intermediate shelves and shelves can be selected based on the length of the workpiece, improving the fixture's practicality. Large gaps are maintained between the fixture components to prevent severe thermal expansion and contraction during heat treatment and to prevent deformation after prolonged use, thus extending its service life.

[0004] However, the existing circulation mechanism uses a fixed structure to install the two bases together. But when the installation is completed, there is no mutual fixing structure between the two bases, which will affect the fixing effect between the two bases. In addition, the holes of the existing induction cooker loading tool base are too small, resulting in uneven air circulation. When the air circulation is uneven, it will lead to poor ventilation and affect the overall operation of the equipment, which has certain drawbacks. Utility Model Content

[0005] To overcome the problems of the existing induction cooker mounting fixture having too small holes in the base, uneven air circulation, and potentially unstable stability between the two bases due to being suspended in mid-air.

[0006] The technical solution of this utility model is as follows: a circulating air uniform circulation mechanism for an induction cooker includes a first fixture base and a second fixture base. The surfaces of the first fixture base and the second fixture base are provided with a plurality of evenly arranged bottom holes. The four ends of the first fixture base are rotatably connected to movable buckles. The left and right sides inside the movable buckles are rotatably connected to connecting plates. A snap-fit ​​plate is fixedly connected between the two connecting plates. The four ends of the second fixture base are fixedly connected to fixing blocks. The interior of each of the four fixing blocks is provided with a snap-fit ​​groove.

[0007] Preferably, by moving the movable buckle, the connecting plate and the snap-on plate can be moved and disengaged from the snap-on groove, allowing for subsequent disassembly of the first and second tooling bases. The reverse movement allows the snap-on plate to engage in the snap-on groove for fixation, thereby strengthening and fixing the first and second tooling bases, preventing them from being suspended and causing instability, and improving their performance.

[0008] Preferably, both the first tooling base and the second tooling base have through holes, through which a column is inserted.

[0009] Preferably, a second mounting base is connected between the first tooling base and the outside of the column, and the first tooling base and the column are installed through the second mounting base.

[0010] Preferably, a first mounting seat is connected between the second tooling base and the outside of the column, and the second tooling base and the column are installed through the first mounting seat.

[0011] Preferably, a lifting ring sleeve is fixedly connected to the upper end face of the column, and a lifting ring body is fixedly connected to the upper end face of the lifting ring sleeve.

[0012] Preferably, multiple heating tubes are installed between the first tooling base and the second tooling base.

[0013] Preferably, the movable buckle and the two connecting plates are rotatably connected by a rotating shaft, and the buckle plate is snapped into the buckle groove.

[0014] The beneficial effects of this utility model are: 1. The circulating air uniform circulation mechanism of this induction cooker increases the circulation of air by enlarging the bottom holes opened inside the first and second tooling bases, thereby achieving the purpose of uniform temperature inside the furnace. At the same time, the overall stability is improved by reinforcing the structure between the two bases. 2. The circulating air circulation mechanism of this induction cooker allows the connecting plate and the buckle plate to move by moving the movable buckle, disengaging from the buckle groove. This enables subsequent disassembly of the first and second fixture bases. The reverse movement allows the buckle plate to engage in the buckle groove for fixation, thus strengthening and fixing the first and second fixture bases, preventing them from being suspended and causing instability, and improving their performance.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-5 This utility model provides an embodiment of a circulating air uniform circulation mechanism for an induction cooker, including a first fixture base 1 and a second fixture base 3. Both the first fixture base 1 and the second fixture base 3 have multiple evenly arranged bottom holes 14 on their surfaces. The four outer ends of the first fixture base 1 are rotatably connected to movable buckles 9. Connecting plates 10 are rotatably connected to the left and right sides inside the movable buckles 9. A snap-fit ​​plate 11 is fixedly connected between two connecting plates 10. The four outer ends of the second fixture base 3 are fixedly connected to fixing blocks 12. Each of the four fixing blocks 12 has a snap-fit ​​groove 13 inside. Figure 1As shown, the heating tube 6 is included. In this application, the structure of the heating tube 6 is a prior art solution. The applicant will not provide a detailed description of the internal structure and components of the heating tube 6 or their connection relationships. Therefore, the above-mentioned structure and connection relationships are all prior art. The applicant has not made any improvements to the components inside the heating tube 6.

[0019] Please see Figure 1 In this embodiment, both the first tooling base 1 and the second tooling base 3 have through holes. A column 4 is inserted through the through holes in the first tooling base 1 and the second tooling base 3. A second mounting seat 8 is connected between the first tooling base 1 and the outside of the column 4. A first mounting seat 7 is connected between the second tooling base 3 and the outside of the column 4. By enlarging the bottom hole 14 inside the first tooling base 1 and the second tooling base 3, the circulation of air is increased to achieve uniform temperature inside the furnace. At the same time, the overall stability is improved by reinforcing the structure between the two bases. By moving the movable buckle 9, the connecting plate 10 and the buckle plate 11 can be moved through its internal rotating shaft.

[0020] Please see Figures 2-5 In this embodiment, a lifting ring sleeve 2 is fixedly connected to the upper end face of the column 4, and a lifting ring body 5 is fixedly connected to the upper end face of the lifting ring sleeve 2. Multiple heating tubes 6 are provided through the first tooling base 1 and the second tooling base 3. A rotating shaft is rotatably connected through the movable buckle 9 and the two connecting plates 10. The buckle plate 11 is snapped into the buckle groove 13, so that it is disengaged from the buckle groove 13, which can be used for subsequent disassembly of the first tooling base 1 and the second tooling base 3. At the same time, through the rotation of the rotating shaft, the connecting plate 10 is moved closer to the inside, and the buckle plate 11 is snapped into the buckle groove 13 to fix it, thereby realizing the strengthening and fixing effect of the first tooling base 1 and the second tooling base 3, preventing them from being suspended and causing instability, and improving their use effect.

[0021] During operation, by enlarging the bottom holes 14 inside the first tooling base 1 and the second tooling base 3, the circulation of air is increased to achieve uniform temperature inside the furnace. At the same time, the overall stability is improved by reinforcing the structure between the two bases. By moving the movable buckle 9, the connecting plate 10 and the snap-fit ​​plate 11 can be moved through their internal rotating shaft, causing them to disengage from the snap-fit ​​groove 13. This allows for subsequent disassembly of the first tooling base 1 and the second tooling base 3. Simultaneously, the rotation of the rotating shaft causes the connecting plate 10 to move inward, while the snap-fit ​​plate 11 engages in the snap-fit ​​groove 13 to fix it. This achieves a reinforced and fixed effect on the first tooling base 1 and the second tooling base 3, preventing them from being suspended and causing instability, and improving their performance.

[0022] By enlarging the bottom hole and increasing the circulation of air, the temperature inside the furnace can be made more uniform. At the same time, by reinforcing the structure between the two bases, the overall stability can be improved. This solves the problems of the existing induction cooker loading tool base hole being too small, uneven circulation of air, and the instability of the two bases due to being suspended.
