Description

Technical Field

[0001] This utility model relates to the field of mica heating plate technology, specifically to a mica heating plate that is easy to install. Background Technology

[0002] Mica heating plates are a type of high-efficiency and durable electric heating element. They use mica plates as the substrate and insulation layer, and nickel-chromium alloy as the heating element. They are characterized by high temperature resistance, good insulation, high heating efficiency, and long service life.

[0003] Traditional mica heating panels require the application of adhesive evenly to the back of the panel before installation. The panel is then adhered to the designated position with pressure to ensure a secure bond. However, over time, the adhesive's strength diminishes, compromising the stability of the connection. To address this, some mica heating panels have pre-drilled screw holes in both the panel and the designated location. After the panel is attached, the screw holes align, and multiple sets of screws secure the panel, ensuring a stable connection. However, this method, using multiple sets of bolts, increases the difficulty of operation in confined spaces and also affects stability. Therefore, a more easily installed mica heating panel is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned defects by providing a mica heating plate that is easy to install, thereby addressing the technical problems that not only increase the difficulty of operation in a confined internal space but also affect the stability of use.

[0005] The objective of this utility model is achieved through the following means:

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mica heating plate that is easy to install, comprising an outer frame, a mica sheet installed in the inner cavity of the outer frame, a connecting handle rotatably connected to all four sides of the front of the outer frame, and a positioning post rotatably connected to all four sides of the back of the outer frame, the positioning post being coaxially connected to the connecting handle, and limit blocks evenly installed on the surface of the positioning post, a positioning cylinder sleeved on the outside of the positioning post, an annular outer plate installed at the inner end of the positioning cylinder, and an inner rotating cylinder movably installed inside the positioning cylinder via a ball bearing, and limit grooves are formed on the inner walls of the positioning cylinder, the annular outer plate, and the inner rotating cylinder, and a fixing cone hole is formed on the surface of the inner rotating cylinder, a sliding groove is also formed on the surface of the annular outer plate, a sliding plate is movably inserted into the sliding groove, and a connecting plate is connected to the bottom of the sliding plate, and a return spring and a fixing cone rod are respectively installed on the upper and lower surfaces of the connecting plate. By first fixing the positioning cylinder at the connection of the preheating furnace, when the outer frame is in contact with the preheating furnace, the positioning column enters the inner cavity of the inner rotating cylinder. The limiting block moves along the limiting groove, so that the surface of the positioning column is in contact with the inner wall of the inner rotating cylinder. The connecting handle drives the positioning column on the outer frame, and the positioning column drives the inner rotating cylinder to rotate inside the positioning cylinder through the limiting block and the limiting groove. When the fixed cone hole rotates in the same direction as the positioning cylinder and corresponds to the position of the fixed cone rod, the connecting plate drives the fixed cone rod to descend under the action of the return spring, and the fixed cone rod is inserted into the inner cavity of the fixed cone hole. The connecting plate also drives the sliding plate to move along the sliding groove of the annular outer plate. On the one hand, this not only reduces the difficulty of operation in the narrow internal space, but also ensures the stability of use. On the other hand, the sliding plate can be raised along the sliding groove, and the connecting plate moves in the same direction as the sliding plate and squeezes the return spring, so that the fixed cone rod moves in the same direction as the sliding plate and separates from the fixed cone hole, thus facilitating disassembly and assembly.

[0007] Preferably, a protective net is also installed on the front end face of the outer frame, and the outer frame and the protective net are connected by bolts. The protective net is installed on the outer frame by bolts, which not only improves the protection of the structure, but also does not hinder heat dissipation.

[0008] Preferably, both the limiting block and the limiting groove are semi-circular in design, and their shapes and positions correspond. The limiting block can move along the limiting groove.

[0009] Preferably, the surface of the sliding plate is further provided with anti-slip grooves, and the sliding plate is generally square in design. The connecting plate is slidably disposed within the inner cavity of the positioning cylinder. The sliding plate can be moved up and down by the anti-slip grooves, and the sliding plate can drive the connecting plate to move up and down within the inner cavity of the positioning cylinder.

[0010] Preferably, the two ends of the return spring are tightly fitted to the inner wall of the positioning cylinder and the surface of the connecting plate, respectively. The connecting plate can drive the return spring to perform a pressing operation on the inner wall of the positioning cylinder, and at the same time, the return spring can drive the connecting plate to perform a reset operation on the inner wall of the positioning cylinder.

[0011] Preferably, the bottom end of the fixed cone rod extends downward through the inner wall of the positioning cylinder, and the shape of the fixed cone rod corresponds to that of the fixed cone hole. When the return spring drives the fixed cone rod to descend along the inner wall of the positioning cylinder via the linkage plate, the fixed cone rod is inserted into the interior of the fixed cone hole.

[0012] The beneficial effects of this utility model are:

[0013] This easy-to-install mica heating plate works by first fixing the positioning cylinder at the connection of the preheating furnace. When the outer frame is in contact with the preheating furnace, the positioning column enters the inner cavity of the inner rotating cylinder. The limiting block moves along the limiting groove, so that the surface of the positioning column is in contact with the inner wall of the inner rotating cylinder. The connecting handle drives the positioning column on the outer frame, and the positioning column drives the inner rotating cylinder to rotate inside the positioning cylinder through the limiting block and the limiting groove. When the fixed cone hole rotates in the same direction as the positioning cylinder and corresponds to the position of the fixed cone rod, the connecting plate drives the fixed cone rod to descend under the action of the return spring, and the fixed cone rod is inserted into the inner cavity of the fixed cone hole. The connecting plate also drives the sliding plate to move along the sliding groove of the annular outer plate. This not only reduces the difficulty of operation in the narrow internal space, but also ensures the stability of use. At the same time, the sliding plate can be raised along the sliding groove, and the connecting plate moves in the same direction as the sliding plate and squeezes the return spring, so that the fixed cone rod moves in the same direction as the sliding plate and separates from the fixed cone hole, thus facilitating disassembly and assembly.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] This utility model provides a technical solution for an easy-to-install mica heating plate, comprising an outer frame 1, a mica sheet 2, a protective net 3, a connecting handle 4, a positioning post 5, a limiting block 6, a positioning cylinder 7, an annular outer plate 8, a sliding groove 9, a sliding plate 10, an inner rotating cylinder 11, a limiting groove 12, a connecting plate 13, a return spring 14, a fixing cone rod 15, and a fixing cone hole 16. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 The inner cavity of the outer frame 1 is fitted with a mica sheet 2, and the front of the outer frame 1 is rotatably connected to a connecting handle 4. The back of the outer frame 1 is rotatably connected to a positioning post 5, and the positioning post 5 is coaxially connected to the connecting handle 4. Limiting blocks 6 are evenly installed on the surface of the positioning post 5. The positioning post 5 is fitted with a positioning cylinder 7, and the inner end of the positioning cylinder 7 is fitted with an annular outer plate 8. The inner rotating cylinder 11 is movably installed inside the positioning cylinder 7 through a ball bearing. Limiting grooves 12 are opened on the inner walls of the positioning cylinder 7, the annular outer plate 8, and the inner rotating cylinder 11. A fixing cone hole 16 is opened on the surface of the inner rotating cylinder 11. A sliding groove 9 is also opened on the surface of the annular outer plate 8. A sliding plate 10 is movably inserted into the sliding groove 9. A connecting plate 13 is connected to the bottom of the sliding plate 10. A return spring 14 and a fixing cone rod 15 are respectively installed on the upper and lower surfaces of the connecting plate 13. By first fixing the positioning cylinder 7 at the connection of the preheating furnace, when the outer frame 1 is in contact with the preheating furnace, the positioning column 5 enters the inner cavity of the inner rotating cylinder 11, and the limiting block 6 moves along the limiting groove 12, so that the surface of the positioning column 5 is in contact with the inner wall of the inner rotating cylinder 11. The connecting handle 4 drives the positioning column 5 on the outer frame 1, and the positioning column 5 drives the inner rotating cylinder 11 to rotate inside the positioning cylinder 7 through the limiting block 6 and the limiting groove 12. When the fixing cone hole 16 rotates in the same direction as the positioning cylinder 7 and corresponds to the position of the fixing cone rod 15, the connecting plate 13 is driven by the return spring 14. The fixed cone rod 15 descends and is inserted into the inner cavity of the fixed cone hole 16. The connecting plate 13 drives the sliding plate 10 to move along the sliding groove 9 of the annular outer plate 8. On the one hand, this not only reduces the difficulty of operation in the narrow internal space, but also ensures the stability of use. On the other hand, the sliding plate 10 can be raised along the sliding groove 9. The connecting plate 13 moves in the same direction as the sliding plate 10 and squeezes the return spring 14, so that the fixed cone rod 15 moves in the same direction as the sliding plate 10 and separates from the fixed cone hole 16, thereby facilitating disassembly and assembly operations.

[0021] Please see Figure 1 The outer frame 1 is also equipped with a protective net 3 on its front end, and the outer frame 1 and the protective net 3 are connected by bolts. The protective net 3 is installed on the outer frame 1 by bolts, which not only improves the protection of this structure, but also does not hinder heat dissipation.

[0022] Please see Figure 2 , Figure 3Both the limiting block 6 and the limiting groove 12 are semi-circular in design, and their shapes and positions correspond. The limiting block 6 can move along the limiting groove 12.

[0023] Please see Figure 4 The sliding plate 10 has anti-slip grooves on its surface and is square in design. The connecting plate 13 is slidably disposed within the cavity of the positioning cylinder 7. The sliding plate 10 can be moved up and down by the anti-slip grooves, and the sliding plate 10 can move the connecting plate 13 up and down within the cavity of the positioning cylinder 7. The two ends of the return spring 14 are tightly fitted to the inner wall of the positioning cylinder 7 and the surface of the connecting plate 13, respectively. The connecting plate 13 can cause the return spring 14 to press against the inner wall of the positioning cylinder 7, and the return spring 14 can cause the connecting plate 13 to reset against the inner wall of the positioning cylinder 7. The bottom end of the fixed cone rod 15 extends downward through the inner wall of the positioning cylinder 7, and the shape of the fixed cone rod 15 corresponds to that of the fixed cone hole 16. When the return spring 14 moves the fixed cone rod 15 down along the inner wall of the positioning cylinder 7 via the connecting plate 13, the fixed cone rod 15 is inserted into the interior of the fixed cone hole 16.

[0024] This scheme involves first fixing the positioning cylinder 7 at the connection point of the preheating furnace. When the outer frame 1 is in contact with the preheating furnace, the positioning column 5 enters the inner cavity of the inner rotating cylinder 11. The limiting block 6 moves along the limiting groove 12, causing the surface of the positioning column 5 to fit against the inner wall of the inner rotating cylinder 11. The connecting handle 4 drives the positioning column 5 on the outer frame 1, and the positioning column 5 drives the inner rotating cylinder 11 to rotate inside the positioning cylinder 7 through the limiting block 6 and the limiting groove 12. When the fixing cone hole 16 rotates in the same direction as the positioning cylinder 7 and the fixing cone rod 1... When positions 5 correspond, the linkage plate 13, under the action of the return spring 14, drives the fixed cone rod 15 to descend, and the fixed cone rod 15 is inserted into the inner cavity of the fixed cone hole 16. The linkage plate 13 drives the sliding plate 10 to move along the sliding groove 9 of the annular outer plate 8. The sliding plate 10 can be raised along the sliding groove 9. The linkage plate 13 moves in the same direction as the sliding plate 10 and squeezes the return spring 14, so that the fixed cone rod 15 moves in the same direction as the sliding plate 10 and separates from the fixed cone hole 16.

[0025] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
