The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0021] Please see Figure 1 As shown, this utility model provides a silent sliding door, including a door body 1. A pulley 2 is fixedly installed at the bottom of the door body 1. A bottom rubber strip 3 is glued to the outside of the pulley 2 and located at the bottom of the door body 1. A handle 4 is fixedly installed on the back of the door body 1. An installation groove 5 is opened on the left side of the front of the door body 1. A retaining spring 8 is fixedly installed on both the upper and lower sides of the inner cavity of the installation groove 5. A first sound-absorbing pad 7 is fixedly installed at the front end of the retaining spring 8. An isolation pad 6 is fixedly installed between the back of the first sound-absorbing pad 7 and the installation groove 5. A second sound-absorbing pad 11 is installed on the right side of the door body 1.

[0022] This technical solution effectively buffers the vibration between the pulley 2 and the track by using the bottom rubber strip 3 at the bottom of the door body 1, reducing friction noise and making the pushing and pulling process quieter. The mounting groove 5 on the left side of the front of the door body 1 is equipped with a clamping spring 8, a first sound-absorbing pad 7 and an isolation pad 6. The clamping spring 8 makes the first sound-absorbing pad 7 fit tightly, enhancing the sound insulation effect; the isolation pad 6 can further block the sound transmission. The second sound-absorbing pad 11 installed on the right side can further reduce the external noise from the side and improve the overall quietness performance. Example

[0023] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, the upper part of the door 1 is equipped with an upper sound insulation pad 9, which is symmetrically arranged and has an overall thickness of one centimeter.

[0024] Adopting such Figure 1 The technical solution shown has that the upper sound insulation pad 9 can not only ensure good sound insulation performance and effectively absorb and block the transmission of sound, but also avoid making the door body 1 structure bulky or increasing unnecessary costs due to excessive thickness. It achieves a good balance between sound insulation effect and practicality. Moreover, the symmetrical arrangement not only helps to improve the overall sound insulation uniformity of the door body 1, but also enhances the stability of the door body 1 structure.

[0025] Secondly, in the technical solution, a crash pad 10 is fixedly installed on the right side of the door body 1 and outside the second sound-absorbing pad 11. The crash pad 10 is made of rubber material. A side separation plate 12 is glued to the inner side of the end of the crash pad 10. The inner side of the side separation plate 12 is connected to the edge of the door body 1. Receiving grooves are opened on both sides of the bottom of the door body 1. The support shaft connected to the surface of the pulley 2 is connected to the inner wall of the receiving groove.

[0026] Its adoption is as follows Figure 1 The technical solution shown has sound insulation or noise reduction components arranged on all sides to block and absorb external sound from all directions, effectively reducing the transmission of indoor and outdoor sound and creating a quiet indoor environment. The side separation plate 12 may have a certain sound insulation effect, which can assist the second noise reduction pad 11 in further blocking the side sound transmission, thus improving the sound insulation system of the door side. The rubber anti-collision pad 10 installed on the outside of the second noise reduction pad 11 on the right side of the door 1 can prevent the door 1 from rigidly colliding with surrounding objects during the opening and closing of the door 1, effectively protecting the door 1 and surrounding objects from damage, while reducing the noise generated by the collision. Example

[0027] This utility model is as follows Figures 1-5 As shown, the first sound-absorbing pad 7 is L-shaped, and the bent part is located inside the mounting groove 5 and is movable; the door body 1 adopts a double-layer design, and is composed of a sound insulation board and a composite board respectively, and the sound insulation board is filled with equally spaced sound insulation cotton.

[0028] By adopting the above technical solution, the movable design allows the first sound-absorbing pad 7 to adaptively adjust its position according to actual usage and the vibration state of the door 1, thereby better exerting the sound insulation effect. The door 1 adopts a double-layer design, and the sound insulation board is filled with equally spaced sound insulation cotton. This structure greatly enhances the sound insulation capability of the door 1 itself. The sound insulation cotton can absorb and disperse the energy of sound, and the double-layer structure further blocks the sound propagation path, effectively reducing the interference of external noise on the indoor environment.

[0029] The working principle of this utility model is as follows: the bottom rubber strip 3 at the bottom of the door body 1 can effectively buffer the vibration between the pulley 2 and the track, reduce friction noise, and make the pushing and pulling process quieter. The mounting groove 5 on the left side of the front of the door body 1 is equipped with a clamping spring 8, a first sound-absorbing pad 7 and an isolation pad 6. The clamping spring 8 makes the first sound-absorbing pad 7 fit tightly, enhancing the sound insulation effect. The isolation pad 6 can further block the sound transmission. The second sound-absorbing pad 11 installed on the right side can further reduce the external noise from the side and improve the overall quiet performance.
