[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3This utility model provides an embodiment of an electromagnetic flat plate heater, including a base plate 1, a guide rail 8 fixedly connected to the top of the base plate 1, and a heating coil 4 slidably connected to the middle of the guide rail 8. First, the heating coil 4 is pushed into the guide rail 8 through an inlet / outlet, so that under the guidance of the guide rail 8, the heating coil 4 can be quickly wound into a uniform coil, improving the winding efficiency of the coil.

[0035] Reference Figure 1 , Figure 2 and Figure 4 A pressure rod 5 is rotatably connected to the top of the base plate 1. A sleeve 26 is fixedly connected to the top of the pressure rod 5. A rotating shaft 14 is rotatably connected to the top of the base plate 1. A knob 7 is fixedly connected to the top of the rotating shaft 14. A crossbar is provided on the top of the knob 7. A connecting plate 17 is fixedly connected to the outer periphery of the knob 7. An insertion rod 16 is fixedly connected to the outer side of the connecting plate 17. The insertion rod 16 is rotatably connected to the middle of the sleeve 26. A locking assembly is installed on the outer periphery of the rotating shaft 14. The locking assembly includes a ratchet 6. The ratchet 6 is fixedly connected to the outer periphery of the rotating shaft 14. A round rod 15 is rotatably connected to the top of the base plate 1. A pawl 11 is rotatably connected to the outer periphery of the round rod 15. The pawl 11 is in contact with the ratchet 6. A fixing block 12 is fixedly connected to the top of the base plate 1. A spring plate 13 is fixedly connected to the middle of the fixing block 12. The spring plate 13 is in contact with the pawl 11. A stop rod 25 is fixedly connected to the top of the base plate 1. The upper surface of the round rod 15 is lower than the lower surface of the connecting plate 17. The rotating pressure rod 5 presses against the heating coil 4 and the guide rail 8, and the rotating knob 7 drives the connecting plate 17, so that the insertion rod 16 on the connecting plate 17 can be inserted into the sleeve 26, thereby fixing the pressure rod 5. This allows the pressure rod 5 to fix the heating coil 4 in the middle of the guide rail 8, ensuring the stability of the heating coil 4. Rotating the knob 7 through the crossbar drives the rotating shaft 14, so that the ratchet 6 on the outer periphery of the rotating shaft 14 can move the pawl 11. Under the action of the spring plate 13, the pawl 11 can be engaged with the ratchet 6. When the ratchet 6 rotates clockwise, it moves 111. Under the action of the blocking rod 25, the ratchet 6 cannot rotate in the opposite direction, ensuring that the insertion rod 16 will not slip out of the sleeve 26. Similarly, after pushing the pawl 11 to separate from the ratchet 6, rotating the knob 7 in the opposite direction can remove the heating coil 4, thereby improving the stability of the heating coil 4 on the base plate 1 and facilitating maintenance.

[0036] Reference Figure 1 , Figure 5 and Figure 6A connecting shaft 19 is rotatably connected to the bottom of the base plate 1. A rotating block 20 is fixedly connected to the bottom of the connecting shaft 19. A protrusion is provided on the outer periphery of the rotating block 20. A circular plate 18 is fixedly connected to the outer periphery of the connecting shaft 19. A rotating rod 21 is rotatably connected to the bottom of the circular plate 18. A mounting base 9 is fixedly connected to the bottom of the mounting base 9. A sliding rod 24 is fixedly connected to the middle of the mounting base 9. A sleeve 10 is slidably connected to the outer periphery of the sliding rod 24. The other end of the rotating rod 21 is rotatably connected to the bottom of the sleeve 10. An elastic component is installed on the outer periphery of the sliding rod 24. A top plate 2 is installed on the top of the base plate 1. A connecting rod 3 is fixedly connected to the outer side of the top plate 2. The sleeve 10 is slidably connected to the middle of the connecting rod 3. The elastic component includes a compression spring 22, which is sleeved on the outer periphery of the sliding rod 24. A groove 23 is opened in the middle of the sleeve 10. The sliding rod 24 is slidably connected to the middle of the groove 23. Rotating the rotating block 20 drives the connecting shaft 19 to rotate. The connecting shaft 19 pulls the rotating rod 21 through the circular plate 18. With the connection of the mounting base 9, the rotating rod 21 can pull the sleeve 10. At the same time, under the action of the sliding groove 23, the sleeve 10 can slide on the outer periphery of the sliding rod 24 and squeeze the compression spring 22. After releasing the rotating block 20, the compression spring 22 can push the sleeve 10 to reset, so that the sleeve 10 can be inserted into the connecting rod 3, so as to quickly connect the bottom plate 1 and the top plate 2, improve the installation speed of the electromagnetic flat plate heater and equipment, and at the same time, the protrusion on the outer periphery of the rotating block 20 facilitates the rotation of the rotating block 20.

[0037] Reference Figure 5 The bottom of the base plate 1 is provided with ventilation slots. The ventilation slots allow the heat generated by the heating coil 4 after it is energized to be discharged, preventing the heating coil 4 from overheating and short-circuiting.

[0038] Working principle: The heating coil 4 is pushed into the guide rail 8 so that the heating coil 4 can be quickly wound into a uniform coil. At the same time, the pressure rod 5 is rotated to press on the heating coil 4 and the guide rail 8, and the knob 7 is rotated to drive the connecting plate 17, so that the insertion rod 16 on the connecting plate 17 can be inserted into the sleeve 26, thereby fixing the pressure rod 5. At the same time, rotating the knob 7 will drive the rotating shaft 14, so that the ratchet 6 on the outer periphery of the rotating shaft 14 can move the pawl 11. Under the action of the spring plate 13 and the blocking rod 25, the ratchet 6 cannot rotate in the opposite direction. Similarly, after pushing the pawl 11 to separate from the ratchet 6, rotating the knob 7 in the opposite direction can remove the heating coil 4, thereby improving the stability of the heating coil 4 on the base plate 1 and facilitating maintenance.

[0039] Rotating the rotating block 20 drives the connecting shaft 19 to rotate. The connecting shaft 19 pulls the rotating rod 21 through the circular plate 18, causing the rotating rod 21 to pull the sleeve 10 to slide on the outer periphery of the slide rod 24 and squeeze the compression spring 22. After releasing the rotating block 20, the sleeve 10 can be pushed back to its original position under the action of the compression spring 22, so that the sleeve 10 can be inserted into the connecting rod 3, so as to quickly connect the bottom plate 1 and the top plate 2 and improve the installation speed of the electromagnetic flat plate heater and equipment.
