Description

Technical Field

[0001] This utility model relates to the field of graphene oxide carbonization heating technology, and in particular to a heating fixture. Background Technology

[0002] Graphene oxide must undergo low-temperature carbonization to become graphene, which can then be used as a material for final applications. The basic structure for low-temperature carbonization consists of two heating plates, one above the other. During heating, gas is released. If there is no exhaust channel, the graphene will be under excessive pressure, causing surface cracking or bulging.

[0003] In the prior art, patent publication number CN218539315U describes a graphene oxide carbonization heating fixture. Although the existing graphene oxide carbonization heating fixture can meet the usage requirements to a certain extent by venting through the venting layer, the direct placement of the heating plates to compress the graphene material makes it easy for it to shift under external force, affecting the graphene reaction. Moreover, the wiring terminals are installed and fixed by bolts and nuts, requiring tools for installation and disassembly, which is very inconvenient and seriously reduces work efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a heating fixture to solve the problems of existing fixtures being easily affected by external factors during processing and having inconsistent operation.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A heating fixture includes a first heating plate and a second heating plate. Two terminal blocks are fixedly installed on the opposite sides of the first and second heating plates. A mounting groove is provided on one side of each terminal block, and a terminal block is movably inserted into the mounting groove. A locking structure is provided between the terminal block and the terminal block. Connecting rods are fixedly installed on both sides of the upper end of the first heating plate. The second heating plate is movably sleeved on the surface of the connecting rods. Two placement plates are sleeved on the surface of the connecting rods. The placement plates are located between the first and second heating plates. A limiting structure is provided between the second heating plate and the connecting rods.

[0006] Furthermore, the surface of the placement plate is uniformly provided with exhaust grooves, the exhaust grooves are located on the side of the placement plate close to the first heating plate and the second heating plate, and the interior of the exhaust grooves is uniformly provided with exhaust holes.

[0007] Furthermore, the limiting structure includes mounting holes, which are opened on both sides of the placement plate and the second heating plate. The connecting rod is inserted into the interior of the mounting holes, and connecting strips are fixedly installed on both sides of the second heating plate.

[0010] Furthermore, a locking rod is fixedly installed in the middle of the movable block. One end of the locking rod is inserted into the installation hole and fixedly connected to the locking tooth plate. An adjustment groove is opened in the middle of the upper end of the connecting strip. Adjusting rods are movably inserted at both ends of the adjustment groove. The adjusting rods are U-shaped, and the two ends of the adjusting rods are fixedly connected to two locking rods located on the same side.

[0011] Furthermore, the locking structure includes a slot, which is formed on the surface of the terminal block. The terminal block has an adjustment slot inside that is connected to the mounting slot. A locking block is movably inserted at the lower end of the adjustment slot. One side of the lower end of the locking block is inclined, and the locking block engages with the slot.

[0016] The technical solution of this utility model will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 and Figure 2 As shown, the heating fixture provided in this embodiment includes a first heating plate 1 and a second heating plate 2. Connecting rods 6 are fixedly installed on both sides of the upper end of the first heating plate 1. The second heating plate 2 is movably sleeved on the surface of the connecting rods 6. Two placement plates 3 are sleeved on the surface of the connecting rods 6. The placement plates 3 are located between the first heating plate 1 and the second heating plate 2. Exhaust grooves 5 are evenly opened on the surface of the placement plates 3. The exhaust grooves 5 are located on the side of the placement plates 3 close to the first heating plate 1 and the second heating plate 2. Exhaust holes 4 are evenly opened inside the exhaust grooves 5. In this embodiment, the user places the graphene material between two placement plates 3, which are positioned between the first heating plate 1 and the second heating plate 2. The connecting rod 6 not only provides fixation but also ensures the relative positions of the first heating plate 1, the second heating plate 2, and the placement plates 3 remain stable, effectively preventing any unnecessary displacement. This design is crucial because any slight displacement may adversely affect the graphene processing and the final product quality. Furthermore, the vent holes 4 and vent grooves 5 designed on the surface of the placement plates 3 also play an important role. They can promptly discharge the gas generated during the heating process, effectively preventing cracking or bulging on the graphene material surface, ensuring the integrity and uniformity of the graphene material, and further improving the efficiency and effectiveness of the entire heating reaction process.

[0018] like Figures 1 to 3As shown, this embodiment provides a heating fixture with a limiting structure between the second heating plate 2 and the connecting rod 6. The limiting structure includes mounting holes on both sides of the placement plate 3 and the second heating plate 2. The connecting rod 6 is inserted into the mounting holes. Connecting strips 7 are fixedly installed on both sides of the second heating plate 2. A groove 11 is provided on one side of the connecting rod 6. A limiting rack 12 is provided inside the groove 11. A retaining plate 13 is movably inserted into the mounting hole of the second heating plate 2 and engages with the limiting rack. Next, both sides of the connecting strip 7 are provided with movable grooves, and movable blocks 15 are movably arranged inside the movable grooves. A compression spring 16 is fixedly installed on one side of the movable block 15, and a locking rod 14 is fixedly installed in the middle of the movable block 15. One end of the locking rod 14 is inserted into the installation hole and fixedly connected to the locking tooth plate 13. An adjustment groove is opened in the middle of the upper end of the connecting strip 7. Adjustment rods 8 are movably inserted at both ends of the adjustment groove. The adjustment rods 8 are U-shaped, and the two ends of the adjustment rods 8 are fixedly connected to the two locking rods 14 located on the same side.

[0019] In this embodiment, when the second heating plate 2 is fitted onto the surface of the connecting bolt, the user needs to manually pull the adjusting rods 8 located on both sides of the device. Pulling the adjusting rods 8 causes the connected locking rod 14 to move, and the movement of the locking rod 14 causes the movable block 15 to move synchronously. During this process, the movement of the movable block 15 will compress the compression spring 16, causing the locking tooth plate 13 connected to one end of the locking rod 14 to move as well. In this way, the second heating plate 2 can be smoothly fitted onto the surface of the connecting rod 6. When the second heating plate 2 contacts the upper end of the placement plate 3 and reaches the predetermined position, the user releases the adjusting rod 8. The locking rod 14, the movable block 15, and the locking tooth plate 13 automatically return to their initial positions under the elastic force of the compression spring 16. The locking tooth plate 13 and the limiting rack 12 engage with each other to form a stable limiting structure, which can effectively limit the position of the second heating plate 2, preventing it from moving up and down during use and avoiding adverse effects on the graphene material processing.

[0020] like Figures 4 to 5 As shown, two terminal blocks 9 are fixedly installed on the side of the first heating plate 1 and the second heating plate 2 that are separated from each other. A mounting groove is opened on one side of the terminal block 9. A terminal block 10 is movably inserted inside the mounting groove. A locking structure is provided between the terminal block 10 and the terminal block 9. The locking structure includes a locking groove 17, which is opened on the surface of the terminal block 10. An adjustment groove connected to the mounting groove is opened inside the terminal block 9. A locking block 18 is provided at the lower end of the adjustment groove. One side of the lower end of the locking block 18 is inclined. The locking block 18 is locked with the locking groove 17. A moving block is fixedly installed at the upper end of the locking block 18. A support spring 20 is fixedly installed at the upper end of the moving block. A pull rod 19 is fixedly installed at the upper end of the moving block. The upper end of the pull rod 19 is inserted through the outside of the terminal block 9 and a pull block 21 is installed thereon.

[0021] In this embodiment, during disassembly, the user manually pulls the pull block 21 upwards. During this pulling process, the pull block 21, via the connected pull rod 19, causes the moving block to move upwards synchronously. During this process, the moving block applies pressure to the support spring 20, causing it to compress and deform. As the moving block rises, the connected locking block 18 also moves, and the lower end of the locking block 18 is pulled out of its original embedded slot 17. Due to the displacement of the locking block 18, the terminal block 10 is pulled out of the mounting slot. This design greatly facilitates the quick disassembly of the terminal block 10.

[0022] During installation, the terminal block 10 is inserted into the mounting slot. When the terminal block 10 contacts the inclined side of the locking block 18, the locking block 18 is pressed into the adjusting slot under external force. This process also compresses the support spring 20. As the terminal block 10 continues to penetrate the mounting slot until it is fully inserted, the locking slot 17 moves to the position below the locking block 18. At this point, under the elastic force of the support spring 20, the locking block 18 quickly pops out and accurately inserts into the locking slot 17, thus firmly securing the terminal block 10 inside the terminal block 9. This design not only ensures the stable fixation of the terminal block 10 but also greatly improves the convenience of quick installation of the terminal block 10.

[0023] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein. Any modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims.
