[0036] See Figure 1-4 , A graphene heating assembly background wall, comprising a frame 1 and a background plate 2; the frame 1 is an inverted U-shaped frame structure, and the left and right sides of the background plate 2 are fixedly installed on the inner side of the frame 1, respectively, Two storage cavities 4 are symmetrically provided on the left and right sides of the front part of the background plate 2. A number of partitions 12 are fixedly installed inside the storage chamber 4. The partitions 12 divide the interior of the storage chamber 4 into multiple cavities for placing sundries. The background plate 2 is an integrated structure composed of a front panel and a back panel. The specific material of the front panel is silica gel. A disc-shaped heating plate 26 is fixedly installed inside the front panel. The heating plate generates heat and passes through the front The panel radiates the interior of the room to increase the internal temperature of the room; the left and right sides of the back panel are symmetrically installed with two heat insulation boards 18, and a number of magnetic stickers 19 are uniformly fixed and installed on the heat insulation board 18 to avoid magnetic The sticker 19 is demagnetized when the background board 2 is fixed, and the material of the back board and the heat insulation board 18 is specifically rock wool;
[0037] In order to further improve the heating effect, the heating plate 26 is a graphene heating plate. Graphene can improve the electrical conductivity of the heating plate 26, thereby improving the thermal conductivity of the heating plate 26, and can also increase the service life of the heating plate 26, avoiding frequent Replacement and maintenance to reduce economic costs;
[0038] The frame 1 is located on the upper side of the background plate 2 and is rotatably installed with a winding roller 6, on which a decorative cloth 7 is wound. The lower side of the decorative cloth 7 is fixedly connected with a lifting rod 8 through the upper and lower sides of the lifting rod 8. The movement drives the decorative cloth 7 to move up and down, and when the decorative cloth 7 has finished covering the background plate 2, the background plate 2 can be used as a background wall; two first screws 3 are installed on the left and right sides of the rack 1 to rotate symmetrically. , The upper ends of the two first screws 3 are connected by a belt 5, and the two first screws 3 are also threadedly connected with a first screw sleeve 11. The first screw 11 is slidingly connected to the inside of the frame 1, and the lifting rod 8 The left and right ends are fixedly connected with the two first screw sleeves 11 by connecting rods. When the first screw sleeve 11 moves up and down, the lifting rod 8 is driven to move up and down; the frame 1 is also fixedly installed with a first motor 9 The output end of the motor 9 is drivingly connected to one of the first screws 11 through the bevel gear set 10, thereby driving the two first screws 11 to rotate in the same direction at the same time.
[0039] A splicing device is provided on the rear side of the frame 1. The splicing device includes a second screw 13 and a ferrule 17. The upper and lower sides of the second screw 13 are symmetrically provided with two external threads with opposite rotation directions, and the second screw 13 It is rotatably installed on one side of the frame 1, and there are two ferrules 17 and fixedly installed on the other side of the frame 1. The second screw 13 is threadedly connected with a second screw sleeve 14, the second screw sleeve 14 Two second screw sleeves 14 are screwed symmetrically on the upper and lower sides. The second screw sleeve 14 is fixedly installed with a hook 15 that cooperates with the clamping sleeve 17, and the rear side of the rack 1 is also fixedly installed to drive the first When the second motor 16 rotates by the two screw rods 13 and the second motor 16 drives the second screw rod 13 to rotate clockwise, the two second hooks 15 move back and engage with the clamping sleeve 17 on the next frame 1 , The two background boards are spliced into one background board.
[0040] In order to facilitate the movement of the background board, the difference between this embodiment and the second embodiment is that an electric push rod 21 is fixedly installed at the lower end of the frame 1, and a rack 22 is fixedly connected to the output end of the electric push rod 21. The frame 1 is rotatably mounted on the inner side of the rack 22 with a round gear 23, which meshes with the rack 22, and a rotating rod 24 is fixedly mounted on the round gear 23. The other end of the rotating rod 24 is rotatably mounted with a caster 25. Change the length of the electric push rod 21 to move the rack 22 up and down, thereby driving the round gear 23 to rotate, and the round gear 23 drives the rotating rod 24 to rotate. When the rotating rod 24 is in a vertical state, the caster 25 is in contact with the ground to facilitate the background The board moves; the left and right sides of the lower part of the background board 2 are symmetrically provided with two grooves 20 for storing casters 25.
[0041] The background plate of the present invention is an integrated structure composed of a front plate and a back plate. The specific material of the front plate is silica gel. The inside of the front plate is fixedly installed with a disc-shaped heating plate. The heating plate generates heat and is aligned through the front plate. The interior of the room is radiated to increase the internal temperature of the room; the present invention is provided with a splicing device on the rear side of the frame, and the splicing device includes a second screw and a ferrule. The upper and lower sides of the second screw are symmetrically provided with two outer surfaces with opposite rotation directions. The second screw is rotatably installed on one side of the frame, and there are two ferrules, and they are fixedly installed on the other side of the frame; the second screw is threadedly connected with a second screw sleeve, Two second screw sleeves are connected with two symmetrical threads on both sides. The second screw sleeve is fixedly installed with a hook that cooperates with the clamping sleeve. The rear side of the frame is also fixedly installed with a second motor that drives the second screw to rotate. When the second motor drives the second screw to rotate clockwise, the two second hooks move back and engage with the card sleeves on the next frame, so that the two background plates are spliced into one background plate; The lower end of the frame is fixedly installed with an electric push rod, and the output end of the electric push rod is fixedly connected with a rack. A circular gear is installed on the inner side of the rack for rotation. The circular gear meshes with the rack, and the circular gear is fixedly installed Rotate the lever, the other end of the rotating lever rotates and the caster is installed. By changing the length of the electric push rod, the rack can move up and down, thereby driving the round gear to rotate. The round gear drives the rotating rod to rotate. When the rotating rod is in a vertical state, the caster Contact with the ground to facilitate the movement of the background board.
