Description

Technical Field

[0001] This utility model relates to the field of soundproofing fabric technology, and in particular to a soundproofing fabric. Background Technology

[0002] In modern society, with the acceleration of urbanization and the continuous development of industrial production, noise pollution has become increasingly serious, negatively impacting people's quality of life and health. Soundproof fabric, as an effective sound insulation and noise reduction material, is widely used in various fields such as building sound insulation, machinery noise reduction, and traffic noise reduction, playing a vital role in improving the acoustic environment.

[0003] Currently, existing sound-damping fabrics on the market have significant defects in terms of installation and storage. During installation, common methods for fixing sound-damping fabrics involve simple rope binding and adhesive bonding, which are insufficient to guarantee the stability of the installation. Rope bindings are easily loosened by external forces, and adhesive bonding weakens in high-temperature and humid environments, causing the sound-damping fabric to wobble and detach, significantly reducing its sound-damping effect. Regarding storage, existing sound-damping fabrics are usually folded or loosely wrapped, which not only easily causes wrinkles and damage to the surface, shortening its lifespan, but also results in the fabric becoming loose after storage, taking up a lot of space, and requiring considerable time to organize before reuse, affecting efficiency. To address these technical problems, this application proposes a new type of sound-damping fabric. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sound-damping cloth. Through the threaded engagement of a semi-circular locking block and a locking ring, the fixing shaft is securely fixed to the mounting post. Simultaneously, an arc-shaped clamping block clamps the storage cylinder, ensuring the sound-damping cloth body is stably fixed during use, preventing shaking and detachment, thus improving stability and guaranteeing sound-damping effectiveness. When not in use, rotating the handle winds the sound-damping cloth body onto the winding shaft, securing it tightly within the storage cylinder using a telescopic belt and locking ring to prevent loosening and damage.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A sound-absorbing fabric includes a storage tube. Two fixing plates are fixedly connected to both sides of the storage tube. A winding shaft is rotatably connected to the inner walls of the two fixing plates. A sound-absorbing fabric body is provided on the outer wall of the winding shaft. A fixing shaft is fixedly connected to one side of the sound-absorbing fabric body. A fixing block is fixedly connected to the outer wall of the fixing shaft. A telescopic strap is provided on the outer wall of the fixing block. One end of the telescopic strap is connected to the fixing shaft via a locking assembly. A support block is fixedly connected to the outer wall of the storage tube. A sliding rod is fixedly connected to the outer wall of the support block. A lifting block is slidably connected to the outer wall of the sliding rod. The lifting block is connected to the outer wall of the support block via a moving assembly. Arc-shaped clamping blocks are fixedly connected to the outer walls of both the lifting block and the support block.

[0007] Furthermore, the movable component includes a threaded rod rotatably connected to the outer wall of the support block, a rotating block fixedly connected to the top end of the threaded rod, and a lifting block threadedly connected to the outer wall of the threaded rod.

[0008] Furthermore, the locking assembly includes a connecting block fixedly connected to one end of the telescopic belt, and semi-circular locking blocks are fixedly connected to the bottom outer wall of the fixed shaft and the outer wall of the connecting block, with locking rings provided on the outer walls of the two semi-circular locking blocks.

[0009] Furthermore, both the outer wall of the semi-circular locking block and the inner wall of the locking ring are provided with threads.

[0010] Furthermore, a throttle is fixedly connected to the outer wall of the winding shaft for controlling the rotation of the winding shaft.

[0011] Furthermore, the inner wall of the arc-shaped clamp is provided with a rubber pad to provide a certain degree of wear resistance.

[0012] Furthermore, the outer wall of the locking ring is provided with an anti-slip pad.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the fixed shaft is firmly fixed to the mounting column by the threaded engagement of the semi-circular locking block and the locking ring. At the same time, the arc-shaped clamping block clamps the storage cylinder, so that the soundproof cloth body can be stably fixed in the required position during use, avoiding problems such as shaking and falling off due to unstable installation. This greatly improves the stability of the soundproof cloth body during use and ensures the stable performance of the soundproofing effect.

[0015] 2. In this utility model, when the sound-absorbing cloth body is not in use, it can be easily wound onto the winding shaft by rotating the handle. This storage method avoids damage that may be caused by randomly stacking the sound-absorbing cloth body. Moreover, by wrapping the telescopic strap around the outside of the storage tube and fixing it with the semi-circular locking block and locking ring, the stored sound-absorbing cloth body can be tightly stored in the storage tube, preventing it from loosening during storage.

[0022] 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.

[0023] Reference Figures 2-4 This utility model provides an embodiment of a sound-absorbing fabric, comprising a storage tube 1, with fixing plates 2 fixedly connected to both sides of the storage tube 1. A winding shaft 13 is rotatably connected to the inner walls of the two fixing plates 2. A sound-absorbing fabric body 4 is provided on the outer wall of the winding shaft 13. A fixing shaft 5 is fixedly connected to one side of the sound-absorbing fabric body 4. A fixing block 6 is fixedly connected to the outer wall of the fixing shaft 5. A telescopic belt 7 is provided on the outer wall of the fixing block 6. A connecting block 14 is fixedly connected to one end of the telescopic belt 7. The bottom outer wall of the fixing shaft 5 and the connecting block 14 are also connected. The outer walls of the storage cylinder 1 are all fixedly connected with semi-circular locking blocks 15. The outer walls of the two semi-circular locking blocks 15 are provided with locking rings 16. The outer walls of the storage cylinder 1 are fixedly connected with support blocks 9. The outer walls of support blocks 9 are fixedly connected with sliding rods 10. The outer walls of sliding rods 10 are slidably connected with lifting blocks 12. A threaded rod 11 is rotatably connected to the outer wall of support blocks 9. A rotating block is fixedly connected to the top of threaded rod 11. Lifting blocks 12 are threadedly connected to the outer walls of threaded rods 11. The outer walls of lifting blocks 12 and support blocks 9 are both fixedly connected with arc-shaped clamping blocks 8.

[0024] Specifically, when the soundproof cloth body 4 is needed, the fixed shaft 5 can be pulled directly to make the winding shaft 13 rotate inside the storage tube 1 and the inner wall of the fixed plate 2, thereby pulling the soundproof cloth body 4 out of the storage tube 1. Next, the telescopic strap 7 is wrapped around the corresponding mounting post. The semi-circular locking block 15 on the outside of the connecting block 14 is engaged with the fixed shaft 5. Then, the connecting block 14 is fixed to the fixed shaft 5 by the engagement of the inner thread of the locking ring 16 and the outer thread of the semi-circular locking block 15, thereby fixing the fixed shaft 5 to the outside of the mounting post. At the same time, the threaded rod 11 is rotated to control the sliding of the lifting block 12 on the slide rod 10, reducing the distance between the two arc-shaped clamping blocks 8, thereby clamping the storage tube 1 with the arc-shaped clamping blocks 8 and fixing it to the outside of another mounting post, completing the installation and fixing of the soundproof cloth body 4, avoiding the instability problem of the traditional hook connection method. When the soundproof cloth body 4 is no longer in use, rotate the handle 3 to wind the soundproof cloth body 4 onto the winding shaft 13, and then wind the telescopic belt 7 around the outside of the storage tube 1. The soundproof cloth body 4 is stored by the two semi-circular locking blocks 15 fitting together and the locking ring 16 being installed on the outside of the semi-circular locking blocks 15.

[0025] Reference Figures 1-3 The outer wall of the semi-circular locking block 15 and the inner wall of the locking ring 16 are both provided with threads. The outer wall of the winding shaft 13 is fixedly connected with a throttle 3 to control the rotation of the winding shaft 13. The inner wall of the arc-shaped clamping block 8 is provided with a rubber pad to provide a certain degree of wear resistance. The outer wall of the locking ring 16 is provided with an anti-slip pad.

[0026] Specifically, the semi-circular locking block 15 and locking ring 16, through threaded engagement, securely fix the fixed shaft 5 to the mounting post. Simultaneously, the connecting block 14 is stably fixed to the fixed shaft 5 via this threaded connection, ensuring the stability of the entire device after installation. The handle 3, fixedly connected to the outer wall of the winding shaft 13, allows operators to manually control the rotation of the winding shaft 13, making the storage and unfolding of the soundproof cloth body 4 more convenient. The rubber pad on the inner wall of the arc-shaped clamping block 8 not only provides good wear resistance but also increases the friction between the clamping block and the storage cylinder 1, further improving clamping stability. The anti-slip pad on the outer wall of the locking ring 16 allows operators to firmly grip the locking ring 16 during installation or removal, preventing operational errors due to slippage and improving operational safety.

[0027] Working principle: When the soundproof cloth body 4 needs to be unfolded for use, the winding shaft 13 can be rotated inside the storage cylinder 1 and the inner wall of the fixing plate 2 by directly pulling the fixed shaft 5, thus pulling the soundproof cloth body 4 out from the storage cylinder 1. Then, the telescopic belt 7 is wound around the required mounting post, and the semi-circular locking block 15 on the outer wall of the connecting block 14 is attached to the fixed shaft 5. The threads on the inner wall of the locking ring 16 and the threads on the outer wall of the semi-circular locking block 15 are engaged to fix the connecting block 14 to the outer wall of the fixed shaft 5, thus fixing the fixed shaft 5 to the outer wall of the required mounting post. Finally, the lifting block 12 is controlled by rotating the threaded rod 11. The sliding of the outer wall of the slide bar 10 brings the distance between the two arc-shaped clamps 8 closer, allowing the two arc-shaped clamps 8 to fix the storage tube 1 to the outer wall of the additional mounting post, thus fixing the soundproof cloth body 4. This avoids the instability caused by the existing soundproof cloth body 4 being connected by hooks. When no longer in use, the soundproof cloth body 4 is wound around the outer wall of the winding shaft 13 by rotating the handle 3, and then wound around the outer wall of the storage tube 1 clockwise by the telescopic belt 7. It is then attached together by two semi-circular locking blocks 15, and the locking ring 16 is installed on the outer wall of the semi-circular locking blocks 15 to store the soundproof cloth body 4.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
