Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a door and window with heat insulation and sound insulation. Background Technology

[0002] As living standards improve, people have higher expectations for the comfort of their living environment. Noise can interfere with daily life and rest, such as traffic noise and the sounds of neighbors' activities. Being in a noisy environment for a long time can affect physical and mental health. The temperature difference between indoors and outdoors can also affect how we feel. In summer, high outdoor temperatures can enter the room, and in winter, heat can be lost from the room, both of which increase the energy consumption of equipment such as air conditioners and heating. Therefore, doors with good heat insulation and sound insulation performance can create a quiet and comfortable indoor environment, reduce energy consumption, and become the key to improving the quality of life.

[0003] Existing technologies, such as the utility model with publication number CN212671507U, disclose a heat-insulating and sound-insulating door and window. This patent uses a door panel, with a rotating shaft movably installed on the outer wall of one end of the door panel. A door frame is movably installed on the outer wall of the side of the door panel away from the rotating shaft. A door core is fixedly installed on the outer wall of the door panel near the door frame. A rubber ring is fixedly installed on the outer wall of the door core. A door handle is movably installed on one outer surface of the door core. This heat-insulating and sound-insulating door and window features a buffer mechanism on the door frame surface. When the door panel and frame make rapid contact, the buffer mechanism, through the interaction of a sliding plate, sliding groove, buffer rod, locking block, and buffer rubber within the buffer groove, ensures that the buffer rubber contacts the door panel first. Then, through the cooperation of a first spring, fixed shaft, first support shaft, first linkage rod, second linkage rod, and second support shaft, the door is buffered backward, preventing rapid contact between the door panel and frame. This effectively extends the lifespan of the door frame and prevents damage caused by impacts. It also solves the problems of existing doors where residents sometimes forget to close them, and in windy weather, strong winds can cause the door to close too heavily, potentially damaging the door frame over time. Furthermore, these doors often have poor sound insulation and lack heat insulation, allowing heat to easily penetrate the door and enter the room when outdoor temperatures are high, causing a continuous rise in indoor temperature and affecting the living environment.

[0004] In daily life, there are problems with existing doors on the market. For example, due to excessively large gaps between the door panel and the door frame, air can easily exchange heat through these gaps. When the outdoor air is too hot, the hot outdoor air will rush into the room through the gaps between the door panel and the door frame. This forces the indoor cooling equipment to operate at a high load to maintain a low temperature, resulting in unnecessary energy waste and economic losses. At the same time, when the door gaps are too large, external noise such as traffic noise, voices, and construction noise can easily enter the room through the gaps, leading to poor sound insulation. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the existing technology where the gap between the door panel and the door frame is too large, allowing air to easily exchange heat through the gap. When the outdoor air is too hot, the hot outdoor air will rush into the room through the gap between the door panel and the door frame, which in turn requires the indoor cooling equipment to operate at a high load to maintain a low temperature, resulting in unnecessary energy waste and economic losses. At the same time, when the door gap is too large, external noise such as traffic noise, human voices, and construction noise can easily enter the room through the gap, resulting in poor sound insulation. Therefore, this utility model proposes a heat-insulating and sound-insulating door and window.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heat-insulating and sound-insulating door and window, comprising a door panel, a door handle, and a sealing assembly. The door handle is disposed on both sides of the door panel, and a door frame is disposed on the side surface of the door panel. A rotating shaft is movably installed on the outer wall of one end of the door panel, and a door frame is movably installed on the outer wall of the side of the rotating shaft away from the door panel. The sealing assembly is disposed inside the door frame, and the sealing assembly includes a mounting groove. The lower surface of the door frame has an mounting groove, and a limit block is fixedly connected to the inner wall of the mounting groove. A linkage rod is fixedly connected to the side surface of the limit block, and a damping sleeve is fixedly connected to the center of the linkage rod. A limit spring is fixedly connected to one side of the damping sleeve, and a linkage frame is fixedly connected to the free end of the limit spring. A circular hole is opened on the upper surface of the linkage frame, and a connecting arm is rotatably connected to the inner wall of the circular hole. A connecting frame is rotatably connected to the side of the connecting arm away from the linkage frame, and a sealing plate is fixedly connected to the surface of the connecting frame.

[0007] Preferably, a limiting groove is formed on the lower surface of the door panel, and a compression spring is fixedly connected to the inner wall of the limiting groove. A baffle is fixedly connected to the free end of the compression spring. There are three compression springs, and the three compression springs are arranged horizontally on the baffle. The compression springs facilitate the application of a restoring force to the baffle to ensure that the door panel is blocked when it is away from the door frame, preventing debris from entering the limiting groove.

[0008] Preferably, a sliding plate is fixedly connected to the side surface of the baffle. The sliding plate is rectangular and is slidably connected to the inner wall of the door panel. There are two sliding plates, which are symmetrically arranged on the left and right sides of the baffle. The sliding plates can cover the side of the limiting groove to prevent debris from entering the limiting groove from the side and thus prevent the limiting groove from becoming blocked.

[0009] Preferably, there are two mounting slots, and the two mounting slots are symmetrically arranged on the door panel. The mounting slots facilitate the installation of sealing parts and ensure that the installation does not affect the use position of the door panel.

[0010] Preferably, the linkage rod passes through the linkage frame and the limiting block. There are two limiting blocks, and the two limiting blocks are symmetrically arranged on the left and right sides of the damping sleeve. The limiting blocks can support the position of the linkage rod to ensure the stability of the linkage rod support.

[0011] Preferably, both ends of the connecting arm are arc-shaped, and there are two connecting arms. The two connecting arms are symmetrically arranged on the left and right sides of the damping sleeve. The connecting arms facilitate the application of a reset force to the limiting spring, thereby moving the position of the sealing plate.

[0012] Preferably, the sealing plate is in contact with the inner wall of the limiting groove, the sealing plate is in contact with the surface of the baffle, and the sealing plate is in contact with the surface of the slider. There are two sealing plates, and the two sealing plates are arranged symmetrically on the door panel. The sealing plates can effectively reduce the airflow between the door panel and the door frame to ensure the sealing between them.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a sealing component, when the user closes the door, they hold the door handle with one hand, pull the door handle downwards, and then pull the door panel inwards. Pulling the door handle moves the door panel towards the door frame. During the movement of the door panel towards the door frame, the door panel contacts the sealing plate. As the door panel moves, the sealing plate moves downwards, compressing the connecting arm. The connecting arm expands outwards, compressing the limit spring. The limit spring deforms under pressure, driving the linkage frame to move towards the damping sleeve until the sealing plate is flush with the bottom surface of the door frame. Then, the limit spring loses its restraint and rebounds to its original position. The linkage moves towards the limit block, and the connecting arm drives the sealing plate to move upward again. Then, the sealing plate pushes the baffle upward, and the baffle squeezes the compression spring. The compression spring is deformed by the squeeze, and at the same time, it drives the sliding plate to move towards the limit groove until the door panel is completely aligned with the door frame. The sealing plate seals the door, and the user can stop pulling the door handle. By setting the sealing component, the gap between the door panel and the door frame can be effectively filled, preventing air convection. When the air cannot flow freely, the heat conducted through the gap will be greatly reduced, thereby increasing the heat insulation effect between the door panel and the door frame.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a heat-insulating and sound-insulating door and window, including a door panel 1, a door handle 2 and a sealing component 5. The door handle 2 is disposed on both sides of the door panel 1. A door frame 3 is disposed on the side surface of the door panel 1. A rotating shaft 4 is movably installed on the outer wall of one end of the door panel 1. The door frame 3 is movably installed on the outer wall of the side of the rotating shaft 4 away from the door panel 1. The sealing component 5 is disposed inside the door frame 3.

[0023] In this embodiment: the sealing component 5 includes a mounting groove 51. The lower surface of the door frame 3 is provided with a mounting groove 51. A limit block 52 is fixedly connected to the inner wall of the mounting groove 51. A linkage rod 53 is fixedly connected to the side surface of the limit block 52. A damping sleeve 54 is fixedly connected to the center of the linkage rod 53. A limit spring 55 is fixedly connected to one side of the damping sleeve 54. A linkage frame 56 is fixedly connected to the free end of the limit spring 55. A circular hole is provided on the upper surface of the linkage frame 56. A connecting arm 57 is rotatably connected to the inner wall of the circular hole. A connecting frame 58 is rotatably connected to the side of the connecting arm 57 away from the linkage frame 56. A sealing plate 59 is fixedly connected to the surface of the connecting frame 58.

[0024] Specifically, a limiting groove 510 is provided on the lower surface of the door panel 1. A compression spring 511 is fixedly connected to the inner wall of the limiting groove 510. A baffle 512 is fixedly connected to the free end of the compression spring 511. There are three compression springs 511, and the three compression springs 511 are arranged horizontally on the baffle 512.

[0025] The effect achieved by the above components is that the compression spring 511 facilitates the application of a reset force to the baffle 512, so as to ensure that the door panel 1 is blocked when it is away from the door frame 3, and prevents debris from entering the limiting groove 510.

[0026] Specifically, a sliding plate 513 is fixedly connected to the side surface of the baffle 512. The sliding plate 513 is rectangular and is slidably connected to the inner wall of the door panel 1. There are two sliding plates 513, and the two sliding plates 513 are symmetrically arranged on the left and right sides of the baffle 512.

[0027] The effect achieved by the above components is that the sliding plate 513 can easily cover the side of the limiting groove 510, preventing debris from entering the limiting groove 510 from the side, thus preventing the limiting groove 510 from becoming blocked.

[0028] Specifically, there are two mounting slots 51, and the two mounting slots 51 are arranged symmetrically on the door panel 1.

[0029] The effect achieved by the above components is that the installation groove 51 facilitates the installation of sealing parts, ensuring that the installation does not affect the use position of the door panel 1.

[0030] Specifically, the linkage rod 53 passes through the linkage frame 56 and the limiting block 52. There are two limiting blocks 52, and the two limiting blocks 52 are located on the damping sleeve 54 and are arranged symmetrically on the left and right.

[0031] The effect achieved by the above components is that the position of the linkage rod 53 can be supported by the limiting block 52 to ensure the stability of the linkage rod 53.

[0032] Specifically, both ends of the connecting arm 57 are arc-shaped, and there are two connecting arms 57, which are symmetrically arranged on the left and right sides of the damping sleeve 54.

[0033] The effect achieved by the above components is that the connecting arm 57 facilitates the application of a reset force to the limiting spring 55, thereby moving the position of the sealing plate 59.

[0034] Specifically, the sealing plate 59 is in contact with the inner wall of the limiting groove 510, the sealing plate 59 is in contact with the surface of the baffle 512, and the sealing plate 59 is in contact with the surface of the slider. There are two sealing plates 59, and the two sealing plates 59 are arranged symmetrically on the door panel 1.

[0035] The effect achieved by the above components is that the airflow between the door panel 1 and the door frame 3 can be effectively reduced by the sealing plate 59, so as to ensure the airtightness between the two.

[0036] Working principle: When the user closes the door, they hold the door handle 2 with one hand and pull it downwards, which in turn pulls the door panel 1 inwards. Pulling the door handle 2 moves the door panel 1 towards the door frame 3. During this movement, the door panel 1 contacts the sealing plate 59. As the door panel 1 moves, the sealing plate 59 moves downwards, pressing the connecting arm 57. The connecting arm 57 expands outwards, pressing the limit spring 55. The limit spring 55 deforms under the pressure, causing the linkage frame 56 to move towards the damping sleeve 54 until the sealing plate 59 is flush with the bottom surface of the door frame 3. Then, the limit spring 55 loses its restraint and rebounds to its original position, causing the linkage frame 56 to move towards the limit block. As the door panel 1 moves in the direction of 52, the connecting arm 57 drives the sealing plate 59 to move upward again. Then, the sealing plate 59 pushes the baffle 512 upward, and the baffle 512 squeezes the compression spring 511. The compression spring 511 is deformed by the compression, and at the same time, it drives the sliding plate 513 to move in the direction of the limiting groove 510 until the door panel 1 is completely aligned with the door frame 3. The sealing plate 59 seals the door, and the user can stop pulling the door handle 2. By setting the sealing component 5, the gap between the door panel 1 and the door frame 3 can be effectively filled, preventing air convection. When the air cannot flow freely, the heat conducted through the gap will be greatly reduced, thereby increasing the heat insulation effect between the door panel 1 and the door frame 3.
