Description

Technical Field

[0001] This utility model relates to the field of polyester fiberboard technology, and in particular to a sound-absorbing folded polyester fiberboard. Background Technology

[0002] Polyester fiberboard, also known as polyester fiber decorative sound-absorbing board, is a decorative material made of polyester fiber through hot pressing. It has sound-absorbing function and does not use formaldehyde or other harmful substances during production. It does not release harmful gases during use and is harmless to the human body and the environment. Moreover, it is lightweight, high-strength, and does not easily deform or break even when subjected to heavy pressure for a long time, ensuring its durability.

[0003] In existing sound-absorbing polyester fiber panels, the installation process typically involves assembling multiple panels. A panel of equal area is placed on each wall surface and secured with adhesive or nails. This method is convenient for covering and fixing multiple panels to a single wall. However, when installing panels on two walls near a corner, not only is it necessary to secure the panels, but the joints near the corner also need reinforcement to prevent warping. This increases the operational steps and significantly reduces the applicability of polyester fiber panels during installation. Therefore, this application proposes a sound-absorbing folded polyester fiber panel suitable for installation on single walls and two walls near a corner. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art that the connection between two polyester fiber boards near the corner of a wall needs to be reinforced, and to propose a sound-absorbing folding polyester fiber board that can be installed on a single wall or two walls near the corner of a wall.

[0005] The technical solution of this utility model: a sound-absorbing folded polyester fiber board, comprising a first board and a second board, and further comprising:

[0006] A connector, one end of which is fixedly mounted on a first plate and the other end of which is fixedly mounted on a second plate, wherein the connector is a rotatable connection structure and is embedded in a groove provided on the side of the first and second plates;

[0007] The positioning structure is located at the joint of the first plate and the second plate. The positioning structure consists of a joint groove and a joint plate. One end of the first plate and the second plate is provided with a joint groove, and the other end of the first plate and the second plate is provided with a joint plate. The joint plate is embedded in the matching joint groove and is tightly engaged with it.

[0008] Optionally, the connector includes a first U-shaped seat and a second U-shaped seat, wherein the first U-shaped seat is embedded and fixedly installed in a groove on the side of the first plate, and the second U-shaped seat is embedded and fixedly installed in a groove on the side of the second plate.

[0009] Optionally, limit grooves are carved on the two opposite inner sidewalls of the first U-shaped seat, and a rotating shaft is movably installed between the two limit grooves. Two connecting rods are fixedly installed on the rotating shaft.

[0010] Optionally, a connecting plate is fixedly installed inside the second U-shaped seat, and one end of the connecting rod passes through a round hole drilled in the connecting plate and is movably connected to it.

[0011] Optionally, a limiting cap is provided on one side of the connecting plate, and a locking bolt is movably inserted through the limiting cap. One end of the connecting rod is in close contact with the limiting cap, and the threaded end of the locking bolt passes through the limiting cap and is threadedly connected to the matching connecting rod.

[0012] Optionally, a spring is movably sleeved on the connecting rod, and the spring is positioned between the connecting plate and the rotating shaft.

[0013] Optionally, an annular baffle is fixedly installed on the outer wall of the connecting rod, and the end of the spring away from the connecting plate is movably connected to the matching annular baffle.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 1 and Figure 4As shown, this utility model proposes a sound-absorbing folding polyester fiberboard, comprising a first board 1 and a second board 3. One side of both the first board 1 and the second board 3 is coated with a PVC coating 4. The high-density characteristics of the PVC coating 4 can block mid-to-low frequency sound waves, complementing the porous sound-absorbing structure of the polyester fiberboard and improving the overall sound absorption effect of the board. A decorative fabric 6 is fixedly adhered to the side of the first board 1 and the second board 3 away from the PVC coating 4. During installation, the PVC coating 4 side is attached to the wall, with the decorative fabric 6 exposed on the outside, improving the overall aesthetics of the board. A connector 2 is fixedly installed at the ends of the first board 1 and the second board 3 that are close to each other. This connector 2 serves as a rotating connection structure between the first board 1 and the second board 3, not only... This design ensures that two boards can be firmly connected as one unit, and allows for easy rotation and adjustment of one board to make the two boards perpendicular to each other, enabling installation on two walls near a corner. One end of both the first board 1 and the second board 3 has a mating groove 5, and the other end of both boards has a mating plate 7 integrally formed with the board body. When the first board 1 and the second board 3 need to be laid flat on a single wall, the mating plate 7 is inserted into the matching mating groove 5, ensuring a stable connection between the two boards and improving the tightness of the assembly. This makes the polyester fiberboard suitable for installation on a single wall or on two adjacent walls near a corner, effectively improving the applicability of the polyester fiberboard during installation.

[0032] like Figures 1-4 As shown, to prevent connector 2 from being exposed on the outer surface of the polyester fiberboard, connector 2 is installed using an embedded installation method. Connector 2 consists of a first U-shaped seat 21 and a second U-shaped seat 22. The first U-shaped seat 21 is embedded and fixedly installed in the groove structure on the side of the first board 1, and the second U-shaped seat 22 is embedded and fixedly installed in the groove structure on the side of the second board 3. Both U-shaped seats are made of PVC material and are hot-pressed and fixed to the matching boards. This not only ensures the firmness of the connection between connector 2 and the board, but also hides connector 2 entirely inside the groove structure. After the first board 1 and the second board 3 are assembled, a spare decorative cloth is glued to the opening of the groove structure to cover and conceal the groove structure, ensuring the aesthetics of the outer surface of the polyester fiberboard.

[0033] Furthermore, to facilitate the rotational adjustment of the first plate 1 and the second plate 3, limit grooves 211 are carved on the two opposing inner sidewalls of the first U-shaped seat 21. A rotating shaft 212 is movably installed between the two limit grooves 211, and two connecting rods 213 are fixedly installed on the rotating shaft 212. A connecting plate 221 is fixedly installed inside the second U-shaped seat 22. One end of the connecting rod 213 passes through a round hole carved on the matching connecting plate 221 and is movably connected to it. When it is necessary to rotate and adjust the first plate 1 and the second plate 3 to a mutually perpendicular state... First, pull the second board 3 away from the first board 1. At this time, the end of the rotating shaft 212 moves away from the first board 1 along the limiting groove 211 until the mating plate 7 is completely removed from the mating groove 5. Then, flip the second board 3 so that the rotating shaft 212 rotates in the limiting groove 211, which facilitates the folding and flipping of the two boards. When the first board 1 and the second board 3 are perpendicular to each other, cover and fix them on the matching wall surface respectively to ensure that the polyester fiber board meets the installation requirements of two relatively independent walls near the corner.

[0034] Secondly, in order to ensure the stability of the connection between the rotating shaft 212 and the connecting plate 221, a limiting cap 222 is provided on one side of the connecting plate 221. When the connecting rod 213 passes through the connecting plate 221 and is in close contact with the matching limiting cap 222, the locking bolt 223 is passed through the limiting cap 222 and its threaded end is threadedly connected to the end of the connecting rod 213. The limiting cap 222 can be fixed on the connecting rod 213. The end of the connecting rod 213 is limited by the limiting cap 222 to prevent the connecting rod 213 from disengaging from the connecting plate 221, which effectively improves the stability of the connection between the rotating shaft 212 and the connecting plate 221.

[0035] like Figure 2 As shown, after the first plate 1 and the second plate 3 are installed, in order to prevent the connector 2 from shaking inside the polyester fiberboard, a spring 214 is movably sleeved on the connecting rod 213. The spring 214 is located between the connecting plate 221 and the rotating shaft 212. The spring 214 can apply a pushing force to the rotating shaft 212, thereby pushing the rotating shaft 212 to a position away from the connecting plate 221. At this time, the rotating shaft 212 is stable on the side of the limiting groove 211 away from the second plate 3, thus preventing the rotating shaft 212 from shaking along the limiting groove 211 and avoiding abnormal noise caused by the shaking of the rotating shaft 212 after the polyester fiberboard is installed.

[0036] Secondly, in order to improve the stability of the spring 214 after installation, an annular baffle 215 is fixedly installed on the outer wall of the connecting rod 213 and on the side near the rotating shaft 212. The annular baffle 215 blocks and limits the end of the spring 214 away from the connecting plate 221, providing a complete support surface for the end of the spring 214 away from the connecting plate 221, avoiding the probability of deformation caused by the spring 214 contacting the arc-shaped outer wall of the rotating shaft 212, and effectively improving the stability of the spring 214 after installation.

[0037] In this embodiment, when polyester fiberboard needs to be laid on a single wall surface, the mating plate 7 is first embedded into the matching mating groove 5, so that the first board 1 and the second board 3 fit together tightly and are spliced ​​as one, ensuring the flatness of the polyester fiberboard after assembly. At this time, the connector 2 is hidden in the groove structure set on the side of the first board 1 and the second board 3. After multiple boards are assembled, the decorative cloth is pasted to cover the groove opening of the groove structure to prevent the connector 2 from being exposed. Embedded installation of the connector 2 can prevent the connector 2 from forming a protruding structure on the outer surface of the board, ensuring the aesthetics of the outer surface of the polyester fiberboard.

[0038] When installing polyester fiberboard on two relatively independent walls near a corner, first pull the second board 3 away from the first board 1, ensuring that the mating plate 7 is completely disengaged from the mating groove 5. At this time, the rotating shaft 212 moves a distance along the limiting groove 211 towards the second board 3, leaving sufficient folding and flipping space between the first board 1 and the second board 3. Then flip the second board 3, at which point the rotating shaft 212 rotates within the limiting groove 211 until the second board 3 and the first board 1 are perpendicular to each other. Finally, fix the first board 1 and the second board 3 to the matching wall. With the ends of the two boards 3 close to each other at the corner of the wall, the connection of the connector 2 ensures that the ends of the first board 1 and the second board 3 close to each other are stably connected as one. After fixing the first board 1 and the second board 3, there is no need to reinforce the part where they are connected, that is, there is no need to fix the part of the board close to the corner of the wall. This effectively prevents the ends of the two boards from lifting up, making installation convenient. This allows the polyester fiberboard to not only meet the requirements of flat splicing on a single wall, but also to be easily installed on two relatively independent walls near the corner of the wall, effectively improving the applicability of polyester fiberboard installation.

[0039] The above specific embodiments are merely several optional embodiments of this utility model.
