Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a multi-layer composite graphene heating plate, comprising:

[0025] The graphene heating plate body 1 has an upper mounting frame 2 and a lower mounting frame 3 on both sides. A heat-conducting plate 4 is fixedly installed on the inner side of both the upper mounting frame 2 and the lower mounting frame 3. The heat-conducting plate 4 is a material with high thermal conductivity and heat resistance, which has little impact on the heat dissipation of the graphene heating plate body 1.

[0026] An arc-shaped groove 15 is provided through one side of both the upper mounting frame 2 and the lower mounting frame 3. The arc-shaped groove 15 is used for the passage of the power cord of the graphene heating plate body 1. An arc-shaped rubber plug 16 is fixedly installed in the arc-shaped groove 15. The two arc-shaped rubber plugs 16 are arranged opposite each other, which can wrap the power cord of the graphene heating plate body 1, thereby playing a sealing role.

[0027] Multiple fixing components are provided between the upper mounting frame 2 and the lower mounting frame 3. The fixing components include a movable column 5, a locking block 7, and a U-shaped plate 8. A rotating shaft 6 is fixedly installed on the lower mounting frame 3, and the rotating shaft 6 passes through one end of the movable column 5 for rotational connection. A torsion spring is provided at the connection between the movable column 5 and the rotating shaft 6, so that after the movable column 5 rotates outward, the torsion spring can drive the movable column 5 to rotate in the opposite direction to reset. A limiting column 9 is fixedly installed on the lower mounting frame 3, and the limiting column 9 is set to abut against the movable column 5, so that the limiting column 9 can limit the movable column 5 and keep the movable column 5 in a vertical state. The locking block 7 is fixedly installed on the movable column 5, and the top of the locking block 7 is set with an inclined surface, so that when the inclined surface of the locking block 7 is pressed, the locking block 7 can be pressed and pushed outward. The U-shaped plate 8 is fixedly installed on the upper mounting frame 2, and the locking block 7 is set to fit into the U-shaped plate 8, so that after the locking block 7 is fitted into the U-shaped plate 8, the upper mounting frame 2 and the lower mounting frame 3 can be locked and fixed.

[0028] Both ends of the lower mounting frame 3 are provided with U-shaped connecting rods 10. The two ends of the U-shaped connecting rods 10 are respectively fixed on two movable columns 5 on the same side. Pressing down on the outer end of the U-shaped connecting rods 10 can drive the two corresponding movable columns 5 to rotate outward, thereby causing the two locking blocks 7 to separate from the corresponding U-shaped plates 8, making it easy to disassemble.

[0029] A sealing assembly is used to seal the space between the upper mounting frame 2 and the lower mounting frame 3. The sealing assembly includes a retaining strip 11 and a sealing gasket 13. The retaining strip 11 is fixedly disposed at the bottom of the upper mounting frame 2. A retaining groove 12 is provided on the lower mounting frame 3, and the retaining strip 11 is inserted into the retaining groove 12. The sealing gasket 13 is disposed at the bottom and on both sides of the retaining groove 12. The retaining strip 11 and the sides of the retaining groove 12 are as follows: Figure 4 All of them are set at an angle, which makes the contact area between the card strip 11 and the sealing gasket 13 larger, thereby improving the sealing effect;

[0030] A sealing strip 14 is fixedly installed at the bottom of the upper mounting frame 2. The sealing strip 14 abuts against the lower mounting frame 3 and plays a sealing role, further improving the sealing performance.

[0031] The detailed working process of this utility model is as follows:

[0032] 1. During installation, place the graphene heating plate body 1 inside the lower mounting frame 3, and then cover the lower mounting frame 3 with the upper mounting frame 2, so that the clip 11 is inserted into the clip groove 12 and pressed against the sealing gasket 13, while the sealing strip 14 is pressed against the lower mounting frame 3 to ensure sealing.

[0033] 2. During this process, the U-shaped plate 8 will press the inclined surface of the clamping block 7, push the clamping block 7 outward, and drive the movable column 5 to rotate. When the U-shaped plate 8 moves to align with the clamping block 7, the movable column 5 will reset under the action of the torsion spring, thereby driving the clamping block 7 to reset and lock into the U-shaped plate 8, thus locking and fixing the upper mounting frame 2 and the lower mounting frame 3.

[0034] 3. When disassembling, press down on the outer ends of the two U-shaped connecting rods 10 at the same time, causing the corresponding movable column 5 to rotate outward, thereby causing the corresponding locking block 7 to separate from the corresponding U-shaped plate 8. At this time, the upper mounting frame 2 and the lower mounting frame 3 can be separated.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
