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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-6As shown, an electric heating plate with a stable structure includes a heating plate body 1, and a limiting mechanism 2 is provided at the rear of the heating plate body 1; it also includes: the limiting mechanism 2 includes a connecting rod 211, one end of which has an inner wall with a mounting groove 215, and a clamp 216 is movably connected to the inner wall of the mounting groove 215; wherein, an insert plate 212 is fixedly connected to the surface of the connecting rod 211 at the end away from the mounting groove 215, and the end surface of the insert plate 212 is arc-shaped; wherein, the inner wall of the connecting rod 211... Furthermore, pressing blocks 213 are slidably connected to both sides of the insert plate 212. One side of the pressing block 213 extends to the outside of the connecting rod 211, and the surface of the pressing block 213 on the outside of the connecting rod 211 is set as an inclined surface. The connecting rod 211 abuts against the insert plate 212 on one side of the inclined surface. A push plate 214 is fixedly connected to one end of the pressing block 213 inside the connecting rod 211. The outer wall of the push plate 214 extends outward through the connecting rod 211, and the outer wall of the push plate 214 is slidably connected to the connecting rod 211. Figure 4 , Figure 5 As shown, when the insert plate 212 is inserted into the connecting sleeve 204, the arc-shaped end of the insert plate 212 can push the abutment block 210 to move away from the insert plate 212. When the abutment block 210 is misaligned with the arc-shaped end, the spring 209 pushes the abutment block 210 to reset. The abutment block 210 limits and locks the mutual ends of the insert plate 212 inside the connecting sleeve 204.

[0031] The limiting mechanism 2 also includes a slider 201. A fastening bolt 202 is threaded to one end of the bottom surface of the slider 201. A guide rod 203 is fixedly connected to the top of the slider 201. The guide rod 203 is vertically positioned, and a connecting sleeve 204 is movably connected to its outer wall. Figure 2 As shown, the connecting sleeve 204 can move up and down along the guide rod 203;

[0032] A threaded sleeve 205 is fixedly connected to one side end of the connecting sleeve 204. A lead screw 206 is threadedly connected to the inner wall of the threaded sleeve 205. Both ends of the lead screw 206 extend to the outside of the threaded sleeve 205. A knob 207 is fixedly connected to the top of the lead screw 206, and a support plate 208 is rotatably connected to the bottom of the lead screw 206. Figure 2 As shown, the support plate 208 abuts against the heat insulation frame 104, thereby fixing the connecting sleeve 204 to the surface of the guide rod 203;

[0033] Two abutments 210 are slidably connected to the inner wall of the top of the connecting sleeve 204. The abutments 210 are symmetrically arranged, with one side of each abutment 210 near the middle of the connecting sleeve 204 being an inclined surface. A spring 209 is fixedly connected to the other end of each abutment 210. The side of the spring 209 is also fixedly connected to the inner wall of the connecting sleeve 204. The side of each abutment 210 abuts against the surface of the insert plate 212 and also makes movable contact with the surface of the pressing block 213. Figure 6When the extrusion block 213 moves toward the insertion plate 212, the extrusion block 213 can push the two side blocks 210 outwards;

[0034] The electric heating plate body 1 includes a base 101. Support legs 102 are fixedly connected to all four sides of the bottom surface of the base 101. A power switch 103 is installed at one end of the front of each support leg 102. A support rail 105 is fixedly installed on the back of each support leg 102. A heat insulation frame 104 is fixedly installed on the top of the base 101. The top surface of the heat insulation frame 104 is in movable contact with a support plate 208. A through groove 107 is opened on the inner side of the support rail 105. A pad 106 is fixedly connected to the bottom surface of the support rail 105 and outside the through groove 107. The top surface of the support rail 105 is slidably connected to a slider 201. A fastening bolt 202 penetrates the inner side of the through groove 107, and the bottom surface of the pad 106 abuts against the fastening bolt 202. Figure 3 As shown, the pad 106 is made of rubber. When the fastening bolt 202 is tightened below the slider 201, the fastening bolt 202 abuts against the pad 106 to increase friction, and the slider 201 is fixed above the support rail 105.

[0035] The working principle of this utility model:

[0036] When heating the container, place the container in the heating area on top of the heating plate body 1, then push the slider 201 to move along the support rail 105, so that the clamp 216 above moves in the horizontal direction. When fixing, tighten the fastening bolt 202, the fastening bolt 202 abuts against the pad 106, so that the slider 201 is fixed above the support rail 105.

[0037] Rotating the knob 207 causes the lead screw 206 to move vertically within the threaded sleeve 205, thereby supporting the heat insulation frame with the support plate 208 and moving the connecting sleeve 204 along the guide rod 203, thereby changing the height of the clamp 216 in the vertical direction and fixing the clamp 216 in a suitable position on the outside of the container.

[0038] After the container is heated, push the push plate 214 towards the connecting sleeve 204, causing the extrusion block 213 to move and press against the end of the insert plate 212. During this time, the extrusion block 213 pushes the inclined side of the abutment block 210, compresses the spring 209, and separates the abutment block 210 from the insert plate 212. Then, hold the connecting rod 211 and separate it from the connecting sleeve 204. The insert plate 212 will then be pulled out from the connecting sleeve 204. At this time, the operator can continue to hold the connecting rod 211 and transfer the heated container through the clamp 216.
