A heating component is arranged at the bottom of the heat-insulating layer, which solves the problem that in the colder seasons, the surface of the metal door is very cold and cannot be directly touched.

[0004] However, the current metal doors have the following problems: If the metal door is not sound-insulated, external noises (such as traffic noises, machine noises, etc.) can easily be transmitted into the room, affecting the quietness and comfort of the room. Therefore, we propose a sound-insulating metal door. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sound-insulating metal door, which can solve the problem that in the related technology, if the metal door is not sound-insulated, external noises (such as traffic noises, machine noises, etc.) can easily be transmitted into the room, affecting the quietness and comfort of the room.

[0006] The technical solution adopted by the utility model is specifically as follows:

[0007] A sound-insulating metal door includes hinges. One side of the hinge is fixedly connected to a door frame, and the other side of the hinge is hinged to a metal door. A door handle is arranged on the side of the metal door, and a sealing device is arranged on the side of the metal door. The sealing device includes a loop-shaped sealing gasket. The side of the loop-shaped sealing gasket is fixedly connected to the side of the metal door. A fixing plate is fixedly connected to the top inner wall of the door frame. An arc-shaped elastic piece is fixedly connected to the side of the fixing plate, and a loop-shaped pressing plate is fixedly connected to the arc surface of the arc-shaped elastic piece.

[0008] The loop-shaped sealing gasket is located on the side of the metal door close to the door frame, and the loop-shaped pressing plate is located on the displacement track of the loop-shaped sealing gasket.

[0009] The outer wall of the loop-shaped extrusion plate is in contact with the inner wall of the door frame, and the loop-shaped extrusion plate is located on the side of the door frame close to the metal door.

[0010] A dehumidifying device for preventing the sealing effect of the loop-shaped sealing gasket from decreasing due to moisture is provided at the bottom of the inner wall of the door frame. The dehumidifying device includes a placement frame, the top of the placement frame is fixedly connected to the bottom of the inner wall of the door frame, several ventilation slots are provided at the top of the placement frame, a dehumidifying block is fixedly connected to the bottom of the inner wall of the placement frame, a fixing block is fixedly connected to the side of the metal door, and several extrusion blocks are fixedly connected to the side of the fixing block.

[0011] The fixing block is located on the side of the metal door close to the door frame, and the dehumidifying block is located on the displacement track of several extrusion blocks.

[0012] The dehumidifying block is located below the fixing plate, and the fixing block is located below the loop-shaped sealing gasket.

[0013] The technical effects achieved by the present utility model are as follows:

[0014] Through the setting of the sealing device, the cooperation of the loop-shaped sealing gasket, the loop-shaped extrusion plate and the arc-shaped elastic sheet enables the movement of the loop-shaped sealing gasket to squeeze the arc-shaped elastic sheet through the loop-shaped extrusion plate, thereby causing the arc-shaped elastic sheet to deform. After the metal door is closed, the arc-shaped elastic sheet will drive the loop-shaped extrusion plate to squeeze the loop-shaped sealing gasket through its own elasticity, so that the loop-shaped sealing gasket can fill the gap between the metal door and the door frame, improving the sealing performance between the metal door and the door frame.

[0015] Through the setting of the dehumidifying device, the cooperation of the dehumidifying block and the loop-shaped sealing gasket enables the dehumidifying block to absorb the moisture around the loop-shaped sealing gasket, thereby keeping the loop-shaped sealing gasket dry and ensuring the sealing effect between the loop-shaped sealing gasket and the metal door and the door frame; at the same time, through the cooperation of the extrusion block, the fixing block, the metal door and the dehumidifying block, when the extrusion block moves to the dehumidifying block, it will squeeze the dehumidifying block, avoiding the problem that the surface of the dehumidifying block is caked, affecting the moisture absorption efficiency of the dehumidifying block.

[0023] In order to make the purpose and advantages of the utility model more clear, the following takes embodiments as examples to specifically describe the utility model. It should be understood that the following text only describes one or several specific implementation manners of the utility model, and does not strictly limit the specific protection scope claimed by the utility model.

[0024] As Figures 1-5 shown, a sound-insulating metal door includes a hinge 2. One side of the hinge 2 is fixedly connected to a door frame 1, and the other side of the hinge 2 is hinged to a metal door 3. The metal door 3 is fixedly connected to the door frame 1 through the hinge 2. A door handle 4 is arranged on the side of the metal door 3, and the door handle 4 is used to control the opening and closing of the metal door 3. A sealing device 5 is arranged on the side of the metal door 3. The sealing device 5 includes a U-shaped sealing gasket 51. The side of the U-shaped sealing gasket 51 is fixedly connected to the side of the metal door 3. The U-shaped sealing gasket 51 seals the metal door 3 and the door frame 1 by itself. A fixing plate 53 is fixedly connected to the top inner wall of the door frame 1. An arc-shaped elastic sheet 54 is fixedly connected to the side of the fixing plate 53. The arc surface of the arc-shaped elastic sheet 54 is fixedly connected to a U-shaped pressing plate 52. The U-shaped pressing plate 52 presses the U-shaped sealing gasket 51, so that the U-shaped sealing gasket 51 can fill the gap between the metal door 3 and the door frame 1, and improve the sealing performance between the metal door 3 and the door frame 1.

[0025] The U-shaped sealing gasket 51 is located on the side of the metal door 3 close to the door frame 1, and the U-shaped pressing plate 52 is located on the displacement track of the U-shaped sealing gasket 51. Such a design can make the U-shaped sealing gasket 51 and the U-shaped pressing plate 52 located at the same horizontal position, ensuring that the U-shaped pressing plate 52 can press the U-shaped sealing gasket 51.

[0026] The outer wall of the U-shaped pressing plate 52 is in contact with the inner wall of the door frame 1, and the U-shaped pressing plate 52 is located on the side of the door frame 1 close to the metal door 3.

[0027] According to the above structure, when the metal door 3 is closed, the movement of the metal door 3 drives the movement of the loop seal 51. The movement of the loop seal 51 squeezes the arc-shaped elastic piece 54 through the loop pressing plate 52, causing the arc-shaped elastic piece 54 to deform. After the metal door 3 is completely closed, the arc-shaped elastic piece 54 drives the loop pressing plate 52 to squeeze the loop seal 51 through its own elastic force, so that the loop seal 51 can fill the gap between the metal door 3 and the door frame 1, improving the sealing performance between the metal door 3 and the door frame 1.

[0028] As Figures 1-5 shown, a dehumidifying device 6 for preventing the loop seal 51 from reducing the sealing effect due to moisture is provided at the bottom of the inner wall of the door frame 1. The dehumidifying device 6 includes a placement frame 61. The top of the placement frame 61 is fixedly connected to the bottom of the inner wall of the door frame 1. A plurality of ventilation grooves 62 are opened at the top of the placement frame 61. A dehumidifying block 63 is fixedly connected to the bottom of the inner wall of the placement frame 61. The dehumidifying block 63 absorbs the moisture around the loop seal 51, thereby keeping the loop seal 51 dry and ensuring the sealing effect between the loop seal 51 and the metal door 3 and the door frame 1. A fixing block 64 is fixedly connected to the side of the metal door 3. A plurality of pressing blocks 65 are fixedly connected to the side of the fixing block 64. When the pressing blocks 65 move to the dehumidifying block 63, they squeeze the dehumidifying block 63, avoiding the problem that the surface of the dehumidifying block 63 becomes hardened, affecting the moisture absorption efficiency of the dehumidifying block 63.

[0029] The fixing block 64 is located on the side of the metal door 3 close to the door frame 1. The dehumidifying block 63 is located on the displacement track of the plurality of pressing blocks 65, so that the movement of the fixing block 64 drives the pressing blocks 65 to squeeze the dehumidifying block 63.

[0030] The dehumidifying block 63 is located below the fixing plate 53, and the fixing block 64 is located below the loop seal 51.

[0031] According to the above structure, the dehumidifying block 63 absorbs the moisture around the loop seal 51, thereby keeping the loop seal 51 dry and ensuring the sealing effect between the loop seal 51 and the metal door 3 and the door frame 1. When the metal door 3 moves, it drives the fixing block 64 to move. The movement of the fixing block 64 drives the pressing blocks 65 to move. When the pressing blocks 65 move to the dehumidifying block 63, they squeeze the dehumidifying block 63, avoiding the problem that the surface of the dehumidifying block 63 becomes hardened, affecting the moisture absorption efficiency of the dehumidifying block 63.

[0032] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special description and limitation.
