[0002] A heating plate is an electrically heated flat plate that is safe and reliable, with a circular or square shape, which generates heat on the plate surface after being powered on without being charged and without open flames. The electric heating plate is installed in heating equipment such as electric heaters or electric heating tables, and can be widely used in various civil and public buildings such as residences, offices, hotels, shopping malls, hospitals, schools, train carriages for mobile heating, and simple movable houses; the electric heating plate can be installed in cooking and heating appliances such as cooking stoves, electric ovens, and electric kettles, and is widely used in various cooking and heating equipment.

[0003] Currently, in the prior art, after the plate surface of the heating plate generates heat for a long time, it is easy to cause the plate surface to deform, resulting in poor use effect of the heating plate and the need to replace the plate surface. However, most of the existing plate surfaces are fixedly installed, and the process of replacing the plate surface is cumbersome, affecting the use of the heating plate. Summary of the Invention

[0004] The purpose of the present invention is to provide a modular heating plate with a built-in safety socket to solve the problems raised in the above background art.

[0005] Technical Solution: A modular heating plate with a built-in safety socket includes two positioning plates and a fixing frame arranged on the positioning plates. Support rods I and II are respectively installed on the surfaces of the two positioning plates. Cavities are provided inside both the support rod I and the support rod II. Two guiding plates are symmetrically arranged inside the support rod I. Positioning pins are fixedly connected to the opposite surfaces of the two guiding plates. A support spring is fixedly connected between the two guiding plates. Two positioning rods are symmetrically installed on the side of the support rod II away from the fixing frame. A protective plate is provided on one side of the fixing frame. Four positioning sleeves are symmetrically arranged on the side of the protective plate facing the fixing frame. Guide columns are slidably connected inside the positioning sleeves. Fixing rods are fixedly connected to the end faces of the guide columns located inside the fixing frame.

[0006] In a further embodiment, two limiting plates are fixedly connected to the inner walls of the upper and lower sides of the fixing frame. Moving grooves for the movement of the guide columns and the fixing rods are provided on the limiting plates.

[0007] In a further embodiment, two installation holes are symmetrically provided inside the positioning sleeves. Fixing springs are provided inside the installation holes of the positioning sleeves. Sliders that slide inside the installation holes of the positioning sleeves are provided on one side of the fixing springs. Fixing pins are fixedly connected to the opposite surfaces of the two sliders.

[0008] In a further embodiment, four fixing holes matching the fixing pins are equidistantly arranged on the outer wall around the guiding column, and an adjusting block is fixedly connected to the end face of the guiding column located outside the fixing frame.

[0009] In a further embodiment, a heating plate main body is installed in the fixing frame, and a socket is installed on the bottom wall of the fixing frame.

[0010] In a further embodiment, limiting rods are fixedly connected to both outer walls of the fixing frame, and guiding grooves for the limiting rods to move are formed on the opposite faces of the first supporting rod and the second supporting rod.

[0011] In a further embodiment, limiting blocks are fixedly connected to both outer walls of the guiding plate, and limiting grooves for the limiting blocks to move are formed on both inner walls of the first supporting rod.

[0012] In a further embodiment, a first through groove and a second through groove are respectively formed on both outer walls of the first supporting rod, and a first protective block and a second protective block are respectively inserted into the first through groove and the second through groove of the first supporting rod.

[0014] Technical effects and advantages of the present invention:

[0015] For the modular heating plate with the built-in safety socket, by rotating the guiding column through the adjusting block, the fixing rod is driven to move, so that the fixing rod corresponds to the moving groove on the limiting plate, and then the fixing rod can be removed from the limiting plate, thus the protective plate can be quickly disassembled, which is more convenient for subsequent maintenance; by inserting the positioning rod on the second supporting rod into another first supporting rod, and under the elastic force of the supporting spring, the positioning pin is inserted into the positioning rod, so as to complete the stable connection between the two heating plates, reduce the displacement of the heating plate caused by external force, and thus affect the heating effect. The modular heating plate with the built-in safety socket is not only convenient for disassembling the protective plate and maintaining the components in the protective frame, but also convenient for connecting multiple heating plates.

Detailed implementation manners

[0026] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0027] For facilitating the connection between multiple heating plates, such as Figures 1 to 4As shown in the figure, support rod one 11 and support rod two 12 are respectively installed on the surfaces of two positioning plates 1 through bolts. Cavities are provided in both support rod one 11 and support rod two 12. Two guide plates 13 are symmetrically arranged in support rod one 11. On the opposite surfaces of the two guide plates 13, positioning pins 14 are fixedly connected through bolts. A support spring 15 is adhesively fixed between the two guide plates 13. On both outer walls of the guide plate 13, limit blocks 16 are fixedly connected. And on both inner walls of support rod one 11, limit grooves for the movement of the limit blocks 16 are provided, which can limit the movement path of the guide plate 13 and ensure that the guide plate 13 can move stably in support rod one 11. On the side of support rod two 12 away from support rod one 11, two positioning rods 19 are symmetrically installed through bolts. The detachable positioning rods 19 can be disassembled when the heating plate is used alone to avoid the positioning rods 19 affecting the outer tube of the heating plate. Positioning holes are provided on the positioning rods 19. One end of the positioning pin 14 is of an inclined structure. On the opposite surfaces of the two positioning rods 19, inclined sliding grooves are provided. When the positioning rod 19 contacts the positioning pin 14, it is convenient for the positioning rod 19 to slide on the surface of the positioning pin 14. Through grooves one and two are respectively provided on both outer walls of support rod one 11. A protection block one 17 and a protection block two 18 are respectively inserted into the through groove one and the through groove two of support rod one 11. By inserting the positioning rod 19 on support rod two 12 into another support rod one 11, the positioning rod 19 presses down the positioning pin 14, thereby compressing the support spring 15. When the positioning pin 14 corresponds to the positioning hole on the positioning rod 19, under the elastic force of the support spring 15, the positioning pin 14 is pushed into the positioning hole of the positioning rod 19, so as to complete the stable connection between the two heating plates. When it is necessary to disassemble the two heating plates, pinch the two guide plates 13 inward. The guide plates 13 compress the support spring 15, so that the positioning pin 14 is separated from the positioning rod 19, and one heating plate can be taken off from the other heating plate.

[0028] To facilitate the disassembly of the protection plate 3 and the maintenance of the components inside the protection frame, such as Figure 1 , Figures 5 to 9 As shown in the figure, a protection frame is provided between support rod one 11 and support rod two 12. On both outer walls of the fixed frame 2, limit rods 23 are fixedly connected through bolts. And on the opposite surfaces of support rod one 11 and support rod two 12, guide grooves for the movement of the limit rods 23 are provided. The limit rods 23 on both sides of the protection frame are respectively inserted into the guide grooves of support rod one 11 and support rod two 12, so as to quickly complete the installation of the protection frame. A heating plate main body 21 is installed in the fixed frame 2. The heating plate main body 21 is a prior art, and its structure will not be elaborated here too much. And a socket 22 is installed on the bottom wall of the fixed frame 2. The socket 22 is electrically connected to the heating plate main body 21;

[0029] One side of the fixed frame 2 is provided with a protective plate 3, and a protective net is arranged on the protective plate 3 to prevent users from directly contacting the heating plate body 21 and getting scalded. On the side of the protective plate 3 facing the fixed frame 2, four positioning sleeves 31 are symmetrically installed by bolts. A guide post 35 is slidably connected in the positioning sleeve 31. The end surface of the guide post 35 located inside the fixed frame 2 is fixedly connected with a fixed rod 36 by bolts. Both the upper and lower inner walls of the fixed frame 2 are fixedly connected with two limiting plates 24. The positions of the limiting plates 24 correspond to the positions of the guide post 35 and the fixed rod 36. A moving groove for the guide post 35 and the fixed rod 36 to move is opened on the limiting plate 24. The fixed rod 36 passes through the moving groove on the limiting plate 24, and the guide post 35 is rotated to cause a dislocation between the fixed rod 36 and the moving groove on the limiting plate 24. The limiting plate 24 can limit the position of the fixed rod 36, thereby fixing the position of the protective plate 3. The positions of the fixed rod 36 and the moving groove on the limiting plate 24 correspond, enabling the quick disassembly of the protective plate 3;

[0030] Two installation holes are symmetrically opened in the positioning sleeve 31. A fixing spring 32 is arranged in the installation hole of the positioning sleeve 31. On one side of the fixing spring 32, there is a slider 33 that slides in the installation hole of the positioning sleeve 31. Fixed pins 34 are fixedly connected to the opposite surfaces of the two sliders 33. A sliding groove for the slider 33 to move is opened in the positioning sleeve 31 to prevent the fixed pin 34 from falling out of the positioning sleeve 31. Four fixing holes matching the fixed pins 34 are equally spaced on the outer peripheral wall of the guide post 35. When the positions of the fixed pins 34 correspond to the fixing holes on the guide post 35, under the elastic force of the fixing spring 32, the fixed pins 34 are pushed into the fixing holes of the guide post 35, thereby fixing the position of the guide post 35 and preventing the guide post 35 from shaking, thus avoiding deviation in the positions of the fixed rod 36 and the moving groove on the limiting plate 24, and further facilitating the disassembly and assembly of the protective plate 3. The end surface of the guide post 35 located outside the fixed frame 2 is fixedly connected with an adjusting block 37 by bolts.

[0031] Working principle:

[0032] When the modular heating plate of the built-in safety socket is in use and it is necessary to install two heating plates, remove the second protective block 18, fix the positioning rod 19 on the second support rod 12, and then insert the positioning rod 19 on the second support rod 12 into another first support rod 11. The positioning rod 19 presses down the positioning pin 14, thereby compressing the support spring 15. When the positioning pin 14 corresponds to the positioning hole on the positioning rod 19, under the elastic force of the support spring 15, the positioning pin 14 is pushed into the positioning hole of the positioning rod 19, thus completing the stable connection between the two heating plates. When it is necessary to disassemble the two heating plates, remove the first protective block 17 from the first support rod 11, pinch the two guide plates 13 inward, the guide plates 13 compress the support spring 15, so that the positioning pin 14 and the positioning rod 19 are separated from each other, and one heating plate can be removed from the other heating plate;

[0033] When it is necessary to disassemble the protective plate 3, rotate the guide post 35 through the adjusting block 37 to drive the fixed rod 36 to rotate, and adjust the fixed rod 36 to the horizontal state. At this time, the fixed rod 36 corresponds to the moving groove on the limiting plate 24. When the fixed pin 34 corresponds to the fixing hole on the guide post 35, under the elastic force of the fixed spring 32, the fixed pin 34 is pushed into the fixing hole of the guide post 35, thereby fixing the position of the guide post 35. Using the same method, adjust all four fixed rods 36 to the horizontal state, and then pull the protective plate 3 outwards to complete the disassembly of the protective plate 3. When it is necessary to install the protective plate 3, install the protective plate 3 on the fixed frame 2. At this time, the fixed rod 36 passes through the moving hole on the limiting plate 24 and moves to the rear of the limiting plate 24. Rotate the guide post 35 by 90° through the adjusting block 37. At this time, the fixed rod 36 is in the vertical state, and the limiting plate 24 restricts the position of the fixed rod 36, thereby fixing the position of the protective plate 3. At the same time, the fixed pin 34 is inserted into the fixing hole of the guide post 35, thereby fixing the position of the guide post 35.
