Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing cotton technology, specifically a sound-absorbing cotton installation structure. Background Technology

[0002] When installing sound-absorbing cotton on a wall panel, it is usually fixed with screws. First, lay out a line on the wall panel and straighten it to make the sound-absorbing cotton neatly arranged and reduce the degree of skewing. After the position of the sound-absorbing cotton is determined, screws are screwed on the corners of the sound-absorbing cotton. The screws pass through the sound-absorbing cotton and fix it to the wall panel. Then, the next sound-absorbing cotton is installed, and finally the installation of the sound-absorbing panel on the entire wall panel is completed.

[0003] However, adjusting the position of the sound-absorbing cotton during installation is time-consuming, and each piece of sound-absorbing cotton is fixed with screws, resulting in a long installation time and poor installation convenience. Utility Model Content

[0030] 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.

[0031] Please see Figure 1As shown, this utility model provides a sound-absorbing cotton installation structure, which includes a prefabricated keel 1 and a connecting component. The prefabricated keel 1 is installed on the building wall panel. In order to reduce the load-bearing capacity of the wall, the prefabricated keel 1 is set as a light steel keel, such as a prefabricated keel 1 made of aluminum alloy. The prefabricated keel 1 has a positioning groove 2 on the side away from the building wall panel. The connecting component includes an integrally set pre-positioning component and a fixing component. The pre-positioning component can be detachably installed into the positioning groove 2. The end of the fixing component away from the pre-positioning component passes through the prefabricated hole 4 of the sound-absorbing cotton 3 and snaps the sound-absorbing cotton 3 into place. This installation structure uses prefabricated keel 1 to replace manual line laying and straightening, which not only improves construction efficiency but also avoids the sound-absorbing cotton 3 from warping during installation due to uneven building wall panel surfaces, thus ensuring the flatness of the sound-absorbing cotton 3 installation. At the same time, the pre-positioning component can move along the positioning groove 2 to accurately position the sound-absorbing cotton 3 and can be adjusted at will, eliminating the need for secondary drilling of the sound-absorbing cotton 3 during installation, thus ensuring the integrity of the sound-absorbing cotton 3 and providing high reusability. Furthermore, the sound-absorbing cotton 3 is snapped together with the fasteners in conjunction with the prefabricated holes 4, which is more convenient than the installation method of fixing each piece with screws.

[0032] In the above, such as Figure 2 As shown, the pre-positioning component includes a fixing plate 5, two sets of clamping parts 8, a first spring 9, and two sets of pressing parts 10. The fixing plate 5 has a mounting groove 6 at one end near the precast keel 1, and guide grooves 7 penetrating the mounting groove 6 are respectively formed on opposite sides of the fixing plate 5. The two sets of clamping parts 8 are located within the mounting grooves 6, with one end of each set extending into the positioning groove 2 and tightly fitting against its inner wall on opposite sides to clamp and fix the fixing plate 5 within the positioning groove 2. The first spring 9 is located between the opposite surfaces of the two sets of clamping parts 8 to provide tension. The two sets of pressing parts 10... The pressing parts 10 are slidably installed into the two sets of guide grooves 7 one by one, and the adjacent ends of the two sets of pressing parts 10 extend into the mounting grooves 6 and connect with the clamping parts 8. The opposite sides of the two sets of pressing parts 10 extend out of the guide grooves 7. Specifically, by pressing the two sets of pressing parts 10 toward each other, the clamping parts 8 are driven to compress the spring and disengage from the inner wall of the positioning groove 2, thereby moving the fixing plate 5 to adjust the installation position of the pre-positioned part, so as to move it to the position corresponding to the pre-made hole 4 of the sound-absorbing cotton 3, and realize the positioning installation.

[0033] In this embodiment, as Figure 2As shown, the positioning groove 2 is configured as a T-shaped structure; one end of each of the two sets of clamping parts 8 is located inside the positioning groove 2 and extends towards the opposite side to the horizontal section of the positioning groove 2, where a locking part 11 is provided. When the first spring 9 is in its maximum compressed state, the opposite ends of the two sets of locking parts 11 can slide out from the vertical section of the positioning groove 2. By providing the locking part 11, when it is locked in the horizontal section of the positioning groove 2, it can limit the fixing plate 5 along the vertical extension direction of the positioning groove 2, further improving the installation reliability of the fixing plate 5.

[0034] In this embodiment, as Figure 2 As shown, the contact surface between the snap-fit ​​part 11 and the horizontal section of the positioning groove 2 is inclined in the horizontal direction, and the thickness of the inclined surface of the snap-fit ​​part 11 gradually increases in the horizontal direction toward the side closer to the clamping part 8; so that when the snap-fit ​​part 11 is worn during installation, under the tension of the spring, the snap-fit ​​part 11 can always be tightly fitted with the inner wall of the positioning groove 2 along the inclined surface, thereby ensuring the installation reliability between the pre-positioning part and the prefabricated keel 1.

[0035] In the above, such as Figure 3 As shown, the fixing component includes a fixing rod 12, a fixing part 14, a supporting block 15, and a second spring 16. The fixing rod 12 is installed onto the pre-positioning component. The interior of the fixing rod 12 is hollow. At least one limiting groove 13 is formed on the outer periphery of the fixing rod 12 away from the pre-positioning component. The limiting groove 13 penetrates the inner wall of the fixing rod 12, and its size decreases sequentially from the inner side to the outer side of the fixing rod 12, facilitating the limiting installation of the fixing part 14 so that the fixing part 14 can slide into the limiting groove 13. For example, the limiting groove 13 can be stepped. The supporting block 15 is located on... The fixing rod 12 is located inside the fixing rod 12 and slides along the axis of the fixing rod 12. It is used to push one end of the fixing part 14 to the extension limiting groove 13 to clamp the sound-absorbing cotton 3 between the fixing part 14 and the prepositioning member, thereby realizing the quick installation of the sound-absorbing cotton 3. The second spring 16 is located inside the fixing rod 12 and is installed at the end of the abutment block 15 away from the fixing part 14. In the initial state, it can ensure that one end of the fixing part 14 always extends to the outside of the limiting groove 13. At the same time, it is convenient to drive the fixing part 14 to reset under the elastic restoring force of the spring when the fixing part 14 is squeezed into the retracting limiting groove 13.

[0036] In this embodiment, as Figure 3As shown, the end of the fixing part 14 extending out of the limiting groove 13 and the side away from the prepositioning member is set as an arc-shaped structure, which makes it easy to align the pre-made hole 4 of the sound-absorbing cotton 3 with the end of the fixing rod 12, and then press the sound-absorbing cotton 3 so that it squeezes the fixing part 14 into the limiting groove 13 along the arc surface of the fixing part 14. When the fixing part 14 has completely passed through the pre-made hole 4, it extends out from the limiting groove 13, thereby snapping and fixing the sound-absorbing cotton 3. During the installation process, no manual operation of the fixing member is required, which further improves the convenience of installation.
