Description

Technical Field

[0001] This utility model relates to the field of ceiling keel technology, and in particular to a noise-reducing concealed track keel integrated structure. Background Technology

[0002] Noise-reducing concealed track keel integrated structure is a new type of structural device applied in the field of building decoration. It is mainly used for the installation of decorative base layers in spaces such as walls and ceilings. The core is to achieve the dual functions of decorative surface installation and noise control through the concealed installation method of track keel combined with sound insulation materials or special structures.

[0003] Traditional track keel structures often use simple bolt connections during installation. This is not only cumbersome, requiring repeated calibration and bolt tightening, which consumes a lot of time and manpower, but also results in poor connection stability. After prolonged use, the connections are prone to loosening, leading to a decrease in structural stability. Furthermore, the lack of effective noise reduction design means that vibrations and noise generated by the friction between the pulleys and the track are directly transmitted, seriously affecting the quietness of the indoor environment and failing to meet the soundproofing requirements of modern buildings. Therefore, a noise-reducing concealed track keel integrated structure is proposed to improve this design. Utility Model Content

[0004] In view of the problems of cumbersome installation process, poor connection stability, and lack of effective noise reduction design in the existing installation process, this utility model is proposed.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a noise-reducing concealed track keel integrated structure, including a keel, a dovetail plate fixedly connected to the center of the top of the keel, a plurality of limiting grooves opened at the top of the dovetail plate, the plurality of limiting grooves being arranged at equal intervals, hook plates symmetrically arranged at the top of the keel, and a C-shaped plate arranged above the dovetail plate and the hook plate.

[0006] The bottom center of the C-shaped plate has a dovetail groove adapted to the dovetail plate, and the two sides of the bottom of the C-shaped plate have hook grooves adapted to the hook plate. A sliding rod is slidably connected inside the bottom plate of the C-shaped plate. A limit block is fixedly connected to the bottom of the sliding rod. The limit block is embedded in the inner wall of the limit groove. A pull plate is fixedly connected to the top of the sliding rod. A spring is sleeved on the upper surface of the sliding rod. The two ends of the spring are respectively connected to the bottom of the pull plate and the top of the bottom plate of the C-shaped plate.

[0007] As a preferred embodiment, an extension plate is fixedly connected to both sides of the keel, an inverted L-shaped rod is fixedly connected to both sides of the C-shaped plate base, a locking block is fixedly connected to the bottom end of the inverted L-shaped rod, and the locking block is fitted into the internal groove of the extension plate.

[0008] As a preferred embodiment, the keel has a pulley groove inside, the bottom wall of the pulley groove has an opening that communicates with the outside, and rubber pads are fixedly connected to both sides of the bottom wall of the pulley groove.

[0009] As a preferred embodiment, the pulley groove is further provided with a number of sound-absorbing grooves, and the number of sound-absorbing grooves are symmetrically arranged.

[0010] As a preferred embodiment, the inner wall of the silencing groove is fixedly connected with a plurality of L-shaped partitions, and the plurality of L-shaped partitions are arranged at equal intervals.

[0011] As a preferred embodiment, the top plate of the C-shaped panel is symmetrically provided with bolt holes, and the C-shaped panel is connected to the ceiling through the bolt holes.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. This utility model provides dual support and limiting through dovetail groove and dovetail plate, hook groove and hook plate, ensuring that the keel is not easy to loosen during long-term use, enhancing the overall stability of the structure, and requiring no complicated tools or professional skills, reducing the installation threshold and greatly improving installation efficiency; the inverted L-shaped rod and extension plate slide groove play an auxiliary support role, further enhancing the stability of the connection. When a component is damaged, simply release the locking of the limiting block and limiting groove, and the C-shaped plate can be quickly disassembled for repair or replacement, reducing maintenance costs and difficulty.

[0014] 2. When the pulley rolls in the pulley groove, the rubber pad can play a preliminary buffering and noise reduction role. The symmetrically distributed sound-absorbing grooves in the pulley groove have L-shaped baffles arranged at equal intervals on the inner wall. After the noise enters the sound-absorbing groove, it is reflected and absorbed by the L-shaped baffles, continuously consuming sound energy, effectively reducing the transmission of noise and realizing the noise reduction function.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a noise-reducing concealed track keel integrated structure, including a keel 1, a dovetail plate 2 fixedly connected to the center of the top of the keel 1, a plurality of limiting grooves 21 opened at the top of the dovetail plate 2, the plurality of limiting grooves 21 are arranged at equal intervals, a hook plate 3 is symmetrically arranged at the top of the keel 1, and a C-shaped plate 4 is arranged above the dovetail plate 2 and the hook plate 3.

[0024] A dovetail groove 46 adapted to the dovetail plate 2 is provided at the center of the bottom end of the C-shaped plate 4. Hook grooves 47 adapted to the hook plate 3 are provided on both sides of the bottom end of the C-shaped plate 4. A sliding rod 41 is slidably connected inside the bottom plate of the C-shaped plate 4. A limiting block 42 is fixedly connected to the bottom end of the sliding rod 41. The limiting block 42 is fitted into the inner wall of the limiting groove 21. A pull plate 43 is fixedly connected to the top end of the sliding rod 41. A spring 44 is sleeved on the upper surface of the sliding rod 41. The two ends of the spring 44 are respectively connected to the bottom end of the pull plate 43 and the top end of the bottom plate of the C-shaped plate 4.

[0025] Both sides of the keel 1 are fixedly connected to extension plates 5, and both sides of the bottom plate of the C-shaped plate 4 are fixedly connected to inverted L-shaped rods 6. The bottom end of the inverted L-shaped rods 6 is fixedly connected to a locking block 61, which is fitted into the internal groove of the extension plate 5.

[0026] The top plate of the C-shaped panel 4 has symmetrical bolt holes 45, and the C-shaped panel 4 is connected to the ceiling through the bolt holes 45.

[0027] Specifically, first, use bolts to connect the C-shaped plate 4 to the ceiling through bolt holes 45. Then, align the dovetail groove 46 at the center of the bottom end of the C-shaped plate 4 with the dovetail plate 2 at the center of the top end of the keel 1. At the same time, align the hook grooves 47 on both sides of the bottom end of the C-shaped plate 4 with the hook plate 3 at the top end of the keel 1. Then, push the C-shaped plate 4 so that the dovetail plate 2 is inserted into the dovetail groove 46 and the hook plate 3 is inserted into the hook groove 47, thus completing the initial fixing.

[0028] During the sliding of the C-shaped plate 4, the locking block 61 at the bottom of the inverted L-shaped rod 6 slides into the groove of the extension plate 5, which plays an auxiliary support role and further enhances the stability of the connection. Then, the pull plate 43 is pulled upward, and the pull plate 43 drives the sliding rod 41 to move upward, so that the limiting block 42 moves upward to the groove inside the bottom plate of the C-shaped plate 4 and stretches the spring 44. When the C-shaped plate 4 slides to the appropriate position, the pull plate 43 is released. Under the elastic force of the spring 44, the pull plate 43 drives the limiting block 42 to move downward through the sliding rod 41, so that the limiting block 42 is locked into the limiting groove 21 of the dovetail plate 2, thereby completing the fixation of the relative position of the C-shaped plate 4 and the keel 1 and realizing the installation of the entire structure.

[0029] This design provides dual support and limiting through the dovetail groove 46 and dovetail plate 2, and the hook groove 47 and hook plate 3, ensuring that the keel 1 is not easy to loosen during long-term use, enhancing the overall stability of the structure. Moreover, it does not require complicated tools and professional skills, reducing the installation threshold and greatly improving installation efficiency. The inverted L-shaped rod 6 and the extension plate 5 slide groove play an auxiliary support role, further enhancing the stability of the connection. When a component is damaged, simply release the locking of the limiting block 42 and the limiting groove 21 to quickly disassemble the C-shaped plate 4 for repair or replacement, reducing maintenance costs and difficulty.

[0030] Reference Figures 1-5 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a pulley groove 11 is provided inside the keel 1, an opening 12 communicating with the outside is provided on the bottom wall of the pulley groove 11, and rubber pads 13 are fixedly connected to both sides of the bottom wall of the pulley groove 11.

[0031] The pulley groove 11 is also provided with several sound-absorbing grooves 14, which are symmetrically arranged.

[0032] The inner wall of the silencing groove 14 is fixedly connected with several L-shaped partitions 15, which are arranged at equal intervals.

[0033] Specifically, when the pulley rolls in the pulley groove 11, the rubber pad 13 can play a preliminary buffering and noise reduction role. The silencing grooves 14 symmetrically distributed in the pulley groove 11 have L-shaped baffles 15 arranged at equal intervals on the inner wall. After the noise enters the silencing groove 14, it is reflected and absorbed by the L-shaped baffles 15, continuously consuming sound energy, effectively reducing the transmission of noise, and realizing the noise reduction function.
