Description

Technical Field

[0001] This utility model relates to an adjustable sound-absorbing module for a cat bed. Background Technology

[0002] A sound-absorbing module is a functional component used to absorb sound and reduce noise. It is usually made of materials with sound-absorbing properties, and through specific structural design and combination, it can effectively reduce the reflection and propagation of sound waves, thereby improving the acoustic environment.

[0003] When using sound-absorbing modules, different modules with varying sound absorption effects are selected based on the specific sound absorption requirements of different environments. Sometimes, when these requirements need to be changed, the sound-absorbing modules need to be replaced. However, disassembling and installing these modules requires professional work, which is time-consuming and labor-intensive. Existing sound-absorbing modules cannot be adjusted to meet different sound absorption requirements. In cat bed design, sometimes it's necessary to increase the sound insulation to prevent excessive meowing from disturbing neighbors, while other times it's necessary to reduce the sound insulation so that the cat can still hear its calls.

[0004] There is a need for a sound-absorbing module that can adjust the absorption effect according to different sound absorption requirements. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable sound-absorbing module for cat beds, which can be adjusted according to different sound absorption requirements to reduce or enhance the sound absorption effect.

[0006] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a mounting frame with a base plate fixed at the bottom; the mounting frame is provided with sound insulation components and protective components arranged sequentially from bottom to top. The sound insulation components include a sound insulation layer fixedly mounted on the base plate, a foldable and retractable sound-absorbing layer, and a driving device for driving the sound-absorbing layer to fold and retract. The sound-absorbing layer has a fixed end and a movable end. The fixed end of the sound-absorbing layer is fixedly mounted on one inner wall of the mounting frame, and the movable end of the sound-absorbing layer extends toward the other inner wall of the mounting frame. The driving device is fixedly mounted on the inner wall of the mounting frame on the side where the fixed end of the sound-absorbing layer is located. The drive end of the device faces the same direction as the extension of the movable end of the sound-absorbing layer. A lead screw is also provided. One end of the lead screw is fixedly mounted on the drive end of the drive device, and the other end of the lead screw extends in the same direction as the extension of the movable end of the sound-absorbing layer and is rotatably mounted on the inner wall of the side facing the movable end of the sound-absorbing layer. A sliding block is connected to the lead screw by a threaded engagement. Both ends of the sliding block extend and slide in engagement with the inner wall of the mounting frame on the corresponding side. The movable end of the sound-absorbing layer is fixedly connected to the sliding block. The sound-absorbing layer folds and expands through the drive of the drive device, the threaded engagement between the lead screw and the sliding block, and the sliding engagement between the sliding block and the inner wall of the mounting frame.

[0007] Furthermore, the protective component includes a flame-retardant layer, a moisture-proof layer, and a finishing layer. Each inner wall of the mounting frame is provided with a placement flange extending towards the center. The placement flanges on each inner wall are set at the same horizontal level. The flame-retardant layer is placed on each placement flange simultaneously. The moisture-proof layer is placed on the side of the flame-retardant layer away from the placement flange. The finishing layer is placed on the side of the moisture-proof layer away from the flame-retardant layer. The side of the finishing layer away from the moisture-proof layer is flush with the top of the mounting frame. The mounting frame is provided with a limiting component for confining the protective component within the mounting frame. The protective component is confined within the mounting frame by the limiting component.

[0008] Furthermore, the limiting component includes a rotating rod and a limiting block. The top of the mounting frame has multiple rotating holes arranged along the contour of the mounting frame, and each rotating hole contains the aforementioned rotating rod. One end of the rotating rod is rotatably disposed in the mounting hole, and the limiting block is fixedly disposed on the other end of the rotating rod. The limiting block acts on the finishing layer through the rotation of the rotating rod. A spring extending toward the top of the mounting frame is fixedly disposed on the placement flange. One end of the spring acts on the placement flange, and the other end of the spring acts on the flame-retardant layer. The protective component forms an installation limit within the mounting frame through the elastic force of the spring and the action of the limiting block on the finishing layer as the rotating rod rotates.

[0009] Furthermore, the sound-absorbing layer is made of glass wool or melamine foam sound-absorbing sponge. The sound-absorbing layer has multiple creases evenly arranged along the folding direction of the sound-absorbing layer. The extension direction of the creases is perpendicular to the folding direction of the sound-absorbing layer. The sound-absorbing layer is folded by the creases and the sliding cooperation of the lead screw and the sliding block.

[0010] Furthermore, the sound insulation layer is fixedly connected to the inner wall of the mounting frame by adhesive, with the adhesive applied around the perimeter of the sound insulation layer.

[0011] Furthermore, the flame-retardant layer, moisture-proof layer, and finishing layer are fixedly connected by adhesive. This utility model has positive effects: (1) This utility model drives the screw to rotate through the drive device to control the sliding block to slide. The sliding block drives the sound-absorbing layer fixed on one end to fold or unfold. Through sound absorption, the sound-absorbing layer folds or unfolds, thereby controlling the contact area of ​​the sound entering the installation frame, so as to weaken or enhance the sound absorption effect. It is easy to adjust according to different sound absorption requirements and has strong adaptability. Existing sound-absorbing modules cannot adjust the sound absorption effect according to different sound absorption requirements. In the cat house, it can increase the sound insulation effect of the cat house to avoid the cat's loud meows disturbing the neighbors, and also reduce the sound insulation effect of the cat house so that the cat can hear the call to the cat.

[0012] (2) The flame retardant layer of this utility model is placed on each placement flange at the same time, the moisture-proof layer is set on the side of the flame retardant layer away from the placement flange, the decorative layer is set on the side of the moisture-proof layer away from the flame retardant layer, the side of the decorative layer away from the moisture-proof layer is flush with the top of the mounting frame, and the mounting frame is provided with a limiting component for restricting the protective component within the mounting frame. The flame retardant layer, the moisture-proof layer and the decorative layer are stacked in sequence to ensure the stability of the protective effect, avoid moisture and mold and fire, and ensure safety.

[0013] (3) The protective component of this utility model is restricted within the mounting frame by a limiting component. The limiting component includes a rotating rod and a limiting block. The protective component forms an installation limit within the mounting frame on the decorative surface by the elastic force of the spring and the action of the limiting block on the rotating rod. The setting of the limiting component allows the protective component to be removed when it is damaged or when the sound-absorbing layer and drive motor need maintenance. This facilitates the replacement of the protective component or the maintenance of the sound-absorbing layer and drive motor, which is efficient and quick.

[0014] (4) The sound-absorbing layer of this utility model is glass wool or melamine foam sound-absorbing sponge. The sound-absorbing layer is provided with multiple creases evenly arranged along the folding direction of the sound-absorbing layer. The extension direction of the creases is perpendicular to the folding direction of the sound-absorbing layer. The sound-absorbing layer is folded by the creases and the sliding cooperation of the screw and the sliding block. The material of glass wool or melamine foam sound-absorbing sponge is easier to fold and roll. The creases can guide the sound-absorbing layer when it is folded, making it easy to set according to the predetermined marks and reducing the loss of sound absorption performance.
