Description

Technical Field

[0001] This utility model relates to the field of silent track technology, specifically a silent track for sliding doors. Background Technology

[0002] Sliding doors are a common type of door design. Their core feature is that they open and close by moving pulleys on a fixed track. Silent tracks are specially designed to reduce noise.

[0003] The existing silent sliding door tracks achieve their sound-absorbing effect by installing sound-absorbing panels and cotton inside the track. However, this method has a drawback: the rollers are in direct contact with the sound-absorbing panels, which may damage the panels due to the rolling friction of the rollers, thus reducing the sound absorption effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a silent sliding door track, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a silent sliding door track, comprising a track body, with sound-absorbing pads fixed on the left and right sides of the track body, a slot being provided at the top of the sound-absorbing pads, a support strip being inserted into the slot, and multiple spiral sound-absorbing holes being provided inside the sound-absorbing pads.

[0006] Preferably, the interior of the spiral sound-absorbing hole is provided with a spiral sound-absorbing cotton strip.

[0007] Preferably, a U-shaped sound-absorbing cotton layer is fixed inside the track body above the support bar, and a U-shaped sound-absorbing plate is fixed inside the U-shaped sound-absorbing cotton layer. Multiple vortex-shaped sound-absorbing holes are opened on the left, right and upper surfaces of the U-shaped sound-absorbing plate.

[0008] Preferably, the interior of the vortex-shaped sound-absorbing hole is provided with a vortex-shaped sound-absorbing cotton strip.

[0009] Preferably, the support bar and the track body are both made of stainless steel or aluminum alloy.

[0010] Preferably, the sound-absorbing pad is made of wood. Beneficial effects

[0011] This invention provides a silent sliding door track. Compared with the prior art, it has the following advantages:

[0012] 1. The silent track of this sliding door is equipped with sound-absorbing pads and support strips. The rollers roll on the support strips instead of the sound-absorbing pads, which prevents the friction generated by the rolling rollers from damaging the sound-absorbing pads and affecting the sound absorption effect.

[0013] 2. The silent track of this sliding door is designed with spiral and vortex sound-absorbing holes. This increases the length of the sound-absorbing holes and the time that sound stays inside them. In addition, the sound-absorbing cotton strips can absorb the sound inside the sound-absorbing holes, further enhancing the sound absorption effect. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a silent sliding door track, including a track body 5. Sound-absorbing pads 1 are fixed to the left and right sides of the track body 5. A slot 10 is provided at the top of each sound-absorbing pad 1, and a support strip 2 is inserted into the slot 10. Multiple spiral sound-absorbing holes 9 are provided inside the sound-absorbing pad 1 to prevent the rollers of the hanging wheel from contacting the sound-absorbing pad 1 and to prevent damage caused by rolling friction. Spiral sound-absorbing cotton strips 8 are provided inside the spiral sound-absorbing holes 9 to further improve the sound absorption effect. The support strip 2 and the track body 5 are made of stainless steel or aluminum alloy, making them less prone to deformation and breakage, and durable. The sound-absorbing pad 1 is made of wood, which reduces weight and provides good support.

[0021] Furthermore, a U-shaped sound-absorbing cotton layer 3 is fixed inside the track body 5 above the support bar 2. A U-shaped sound-absorbing plate 4 is fixed inside the U-shaped sound-absorbing cotton layer 3. Multiple vortex-shaped sound-absorbing holes 6 are opened on the left, right and upper surfaces of the U-shaped sound-absorbing plate 4. This can reduce the noise inside the track body 5. A vortex-shaped sound-absorbing cotton strip 7 is provided inside the vortex-shaped sound-absorbing hole 6. This can improve the sound absorption effect of the vortex-shaped sound-absorbing hole 6.

[0022] During operation, the sliding door's rollers roll on the support strip 2, and the noise from the support strip 2 enters the interior of the spiral sound-absorbing hole 9. The noise rubs and vibrates against the air inside the spiral sound-absorbing hole 9 and the hole wall, thereby consuming sound energy and reducing noise. This not only protects the sound-absorbing pad 1 but also reduces noise. At the same time, the vortex sound-absorbing hole 6 absorbs the noise inside the track body 5, reducing the noise from spreading outward. Moreover, the spiral sound-absorbing hole 9 and the vortex sound-absorbing hole 6 are longer than ordinary sound-absorbing holes, which can increase the time that the sound stays inside the sound-absorbing hole. Furthermore, the sound-absorbing cotton strip can further absorb the sound inside the sound-absorbing hole, enhancing the sound absorption effect and reducing noise transmission.
