[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0021] Example 1
[0022] This utility model provides an auxiliary device for sound and heat insulation of passenger room doors, such as... Figures 1 to 5As shown, the device includes a door frame 1, a guest room door 2 hinged inside the door frame 1, a handle 3 fixedly installed on the front and back of the guest room door 2, a touch switch 4 fixedly installed below the handle 3 on the front of the guest room door 2, the touch switch 4 being electrically connected to a motor 104, a water tank 5 fixedly installed inside the guest room door 2, a sound-absorbing panel 6 fixedly connected to one end of the water tank 5 (the sound-absorbing panel 6 is made of honeycomb material), a heat insulation panel 7 fixedly connected to the other end of the water tank 5 (the heat insulation panel 7 is made of polystyrene), a water inlet pipe 8 fixedly connected to the top of the outer surface of the water tank 5, a water outlet pipe 9 fixedly connected to the bottom of the outer surface of the water tank 5, and a sealing assembly 10 movably connected inside the bottom of the guest room door 2.
[0023] like Figure 1 and Figure 5 As shown, the sealing assembly 10 includes a movable plate 101 movably connected to the bottom of the passenger door 2. A threaded sleeve 102 is fixedly connected to the top of the movable plate 101. A threaded rod 103 is threadedly connected inside the threaded sleeve 102. A motor 104 is fixedly connected to the top of the threaded rod 103. The top of the motor 104 is fixedly connected to the inside of the passenger door 2, and the bottom of the threaded rod 103 is rotatably connected to the inside of the passenger door 2. A sealing plate 105 is fixedly connected to the bottom of the movable plate 101. The motor 104 is started by a touch switch 4, and the output of the motor 104 is... The rotation drives the threaded rod 103 to rotate synchronously. The rotation of the threaded rod 103 drives the threaded sleeve 102 to move downward. The downward movement of the threaded sleeve 102 drives the movable plate 101 to move downward synchronously. The movement of the movable plate 101 drives the sealing plate 105 to move downward synchronously. As the sealing plate 105 moves, it is squeezed and tightly adheres to the ground, thus forming a sealing effect. This effectively seals the gap between the passenger door 2 and the ground, thereby blocking the transmission of external sound and heat, and effectively improving the sound insulation and heat insulation performance of the passenger door 2.
[0024] like Figure 1 and Figure 3 As shown, the outer surfaces of the sound-absorbing panel 6 and the heat insulation panel 7 are both fixedly connected to the inside of the passenger door 2. The heat insulation panel 7 is located at the front of the passenger door 2, and the sound-absorbing panel 6 is located at the back of the passenger door 2. First, external heat is conducted to the outer surface of the passenger door 2, and then to the surface of the heat insulation panel 7. The heat insulation panel 7 can effectively reduce heat conduction. After passing through the heat insulation panel 7, the heat is conducted to the water tank 5. The water inside the water tank 5 absorbs heat and also provides sound insulation. When sound reaches the water tank 5, it is blocked and absorbed by the water, thereby reducing the sound intensity. After passing through the water tank 5, the sound is transmitted to the sound-absorbing panel 6. The sound-absorbing panel 6 can perform secondary sound insulation treatment, further reducing sound penetration and noise pollution, and effectively improving the sound insulation and heat insulation performance of the passenger door 2.
[0025] like Figure 1 and Figure 5As shown, limit blocks are fixedly connected to the top of both ends of the movable plate 101. The outer surface of the limit blocks is movably connected to the inside of the passenger door 2 to prevent the movable plate 101 from shaking when it moves, thereby improving the stability of the movable plate 101 when it moves.
[0026] like Figure 1 and Figure 5 As shown, the sealing plate 105 is made of rubber. The length and width of the sealing plate 105 are equal to the length and width of the passenger door 2, respectively. The sealing plate 105 will be tightly pressed against the ground by the movable plate 101, thereby forming a sealing effect, blocking the transmission of external sound and heat, and effectively improving the sound insulation and heat insulation performance of the passenger door 2.
[0027] like Figure 1 and Figure 3 As shown, both the inlet pipe 8 and the outlet pipe 9 have a sealing cap connected to their outer surfaces by threads. By rotating and removing the sealing cap, the water tank 5 can be drained or drained, respectively.
[0028] Working principle: In actual use, when the user opens the guest room door 2 through the handle 3 on the back and enters the bedroom, the motor 104 is started by the touch switch 4. The output end of the motor 104 rotates, driving the threaded rod 103 to rotate synchronously. The rotation of the threaded rod 103 drives the threaded sleeve 102 to move downward. The downward movement of the threaded sleeve 102 drives the movable plate 101 to move downward synchronously. The movement of the movable plate 101 drives the sealing plate 105 to move downward synchronously. As the sealing plate 105 moves, it is squeezed and tightly adheres to the ground, thus forming a sealing effect. This effectively seals the gap between the guest room door 2 and the ground, thereby blocking the transmission of external sound and heat, and effectively improving the sound insulation and heat insulation performance of the guest room door 2.
[0029] Then, when external heat and sound are transmitted from the guest room door 2 to the bedroom, the external heat is first conducted to the outer surface of the guest room door 2, and then to the surface of the heat insulation board 7. The heat insulation board 7 can effectively reduce heat conduction. After passing through the heat insulation board 7, the heat will be conducted to the water tank 5. The water inside the water tank 5 absorbs heat and also provides sound insulation. When the sound reaches the water tank 5, it will be blocked and absorbed by the water, thereby reducing the sound intensity. After passing through the water tank 5, the sound will be transmitted to the sound-absorbing board 6. The sound-absorbing board 6 can perform secondary sound insulation treatment, which can block and absorb external sound and heat, effectively reducing sound penetration and noise pollution, while also reducing heat conduction, thus effectively improving the sound insulation and heat insulation performance of the guest room door 2.
[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
