Description

Technical Field

[0001] This utility model relates to the field of decorative panel technology, and in particular to a tunnel sidewall decorative panel structure. Background Technology

[0002] A tunnel is an artificial passage built underground, inside mountains, or underwater for purposes such as transportation, water conservancy, and municipal works. It represents a significant achievement of humankind in overcoming natural obstacles through engineering technology. Tunnels can be classified into various types according to different criteria, such as traffic tunnels, water conservancy tunnels, and municipal tunnels. In traffic tunnels, decorative panels are typically installed on the tunnel sidewalls.

[0003] Currently, in the existing tunnel decorative panel installation process, the connection between the decorative panels and the pre-installed mounting brackets on the tunnel sidewalls relies heavily on bolts. Since tunnel sidewall decoration often requires a large number of decorative panels, workers need to tighten the bolts on each panel individually. This results in a very high frequency of repetitive screw-tightening actions, which not only prolongs the installation work time but also greatly increases the labor intensity. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a tunnel sidewall decorative panel structure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tunnel sidewall decorative panel structure, including a mounting frame and a decorative panel. Two mounting seats are horizontally spaced at the lower part of the mounting frame on the side away from the tunnel inner wall. A rotating shaft is horizontally rotatably arranged between the two mounting seats. A connecting seat is fixedly arranged on the rotating shaft. A lower U-shaped plate with an upward opening is arranged on the connecting seat. An upper U-shaped plate with a downward opening is vertically slidably arranged at the upper part of the mounting frame on the side away from the tunnel inner wall. The top of the decorative panel is inserted into the upper U-shaped plate, and the bottom is inserted into the lower U-shaped plate. A fixing component is provided on the upper U-shaped plate to fix the upper U-shaped plate to the mounting frame when the decorative panel is inserted into the upper U-shaped plate and the lower U-shaped plate.

[0006] By adopting the above technical solution, which includes a mounting frame, a lower U-shaped plate, an upper U-shaped plate, and a fixing component, during installation, the connecting seat and the lower U-shaped plate are first slightly rotated outwards to allow sufficient space for the lower part of the decorative panel to be inserted. Then, the lower part of the decorative panel is inserted into the lower U-shaped plate for initial positioning. Next, the decorative panel is pushed towards the mounting frame. At this time, the decorative panel will cause the lower U-shaped plate and the connecting seat to rotate inwards around the axis of rotation, gradually bringing the decorative panel closer to the mounting frame. Then, the upper U-shaped plate is adjusted to slide vertically downwards along the mounting frame, allowing it to engage with the top of the decorative panel, thus fixing both ends of the decorative panel. Finally, the fixing component locks the position of the upper U-shaped plate onto the mounting frame, ensuring that the overall installation of the decorative panel is firm, stable, and reliable. Installation is relatively convenient, reducing installation time and the labor intensity of workers.

[0007] Furthermore, the fixing component includes upright plates horizontally spaced on the upper U-shaped plate, with horizontal sliding holes on the upright plates. A sliding rod is slidably disposed in both sliding holes. The mounting frame has fixing holes, and the position of the upright plates and the upper U-shaped plate is fixed when the end of the sliding rod is placed in the fixing holes.

[0008] By adopting the above technical solution, a vertical plate, a sliding rod, and a fixing hole are set. When the end of the sliding rod is placed in the fixing hole, the position of the vertical plate and the upper U-shaped plate is fixed.

[0009] Furthermore, a retaining ring is fixedly sleeved on the slide rod between the two upright plates, a compression spring is sleeved on the slide rod between the retaining ring and the upright plate away from the mounting frame, and a handle is provided at the end of the slide rod away from the mounting frame.

[0010] By adopting the above technical solution, a retaining ring, a compression spring, and a handle are set up. The compression spring provides elastic force to the retaining ring and the slide rod in the direction of the mounting frame, ensuring that the end of the slide rod is stably inserted into the fixing hole in the fixed state.

[0011] Furthermore, a torsion spring is fitted onto the rotating shaft, and the torsion spring provides the connecting seat with a spring force to rotate away from the mounting frame.

[0012] By adopting the above technical solution and setting a torsion spring, when the decorative panel needs to be replaced, after the upper U-shaped plate is slid upward, the torsion spring provides elastic force to make the connecting seat and the lower U-shaped plate rotate away from the mounting frame, making it easier for the staff to remove the decorative panel from the lower U-shaped plate.

[0013] Furthermore, the mounting base has a horizontally formed circular hole, the rotating shaft is rotatably connected to the circular hole, the mounting base also has an arc-shaped groove, the arc-shaped groove is connected to the circular hole, and a limiting block connected to the rotating shaft is slidably disposed in the arc-shaped groove.

[0014] By adopting the above technical solution, an arc-shaped groove and a limiting block are set. When the rotating shaft rotates, it drives the limiting block to slide in the arc-shaped groove. The arc-shaped groove restricts the sliding of the limiting block, thereby limiting the rotation angle of the rotating shaft, and thus limiting the rotation angle of the connecting seat and the lower U-shaped plate.

[0015] Furthermore, the mounting frame has two spaced-apart sliding grooves, and a slider connected to the upper U-shaped plate is slidably disposed in the sliding groove.

[0016] By adopting the above technical solution, and setting up sliding grooves and sliders, the stability of the upper U-shaped plate sliding is ensured.

[0017] Furthermore, two first cones are horizontally spaced within the lower U-shaped plate, and a first connecting hole is provided at the bottom of the mounting frame corresponding to the first cones. Two second cones are horizontally spaced within the upper U-shaped plate, and a second connecting hole is provided at the top of the mounting frame corresponding to the second cones.

[0018] By adopting the above technical solution, a first cone, a first connecting hole, a second cone, and a second connecting hole are provided. When the decorative panel mates with the lower U-shaped plate, the first cone is inserted into the first connecting hole; when the decorative panel mates with the upper U-shaped plate, the second cone is inserted into the second connecting hole. The first and second cones restrict the position of the decorative panel along the length of the lower U-shaped plate.

[0019] Furthermore, the mounting frame is provided with two vertically spaced connecting plates, and two horizontally spaced connecting columns are provided on the connecting plates. A fixing plate is provided on the side of the connecting columns away from the connecting plates, and four mounting holes are provided on the fixing plate in a rectangular array.

[0020] In summary, this utility model has the following beneficial effects: This application includes an installation frame, a lower U-shaped plate, an upper U-shaped plate, and a fixing component. During installation, the connecting seat and the lower U-shaped plate are first slightly rotated outwards to allow sufficient space for the lower part of the decorative panel to be inserted. Then, the lower part of the decorative panel is inserted into the lower U-shaped plate to complete the initial positioning. Next, the decorative panel is pushed towards the installation frame. At this time, the decorative panel will cause the lower U-shaped plate and the connecting seat to rotate inwards around the axis of rotation, gradually bringing the decorative panel closer to the installation frame. Then, the upper U-shaped plate is adjusted to slide vertically downwards along the installation frame, allowing it to engage with the top of the decorative panel, thus fixing both ends of the decorative panel. Finally, the fixing component locks the position of the upper U-shaped plate onto the installation frame, ensuring that the overall installation of the decorative panel is firm, stable, and reliable. Installation is relatively convenient, reducing installation time and the labor intensity of workers. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-7As shown in the illustration, this application discloses a tunnel sidewall decorative panel structure, including a mounting frame 10, a decorative panel 20, a lower U-shaped plate 33, an upper U-shaped plate 40, and a fixing assembly 50. Two mounting seats 30 are horizontally spaced at the lower part of the mounting frame 10 on the side away from the tunnel inner wall. A rotating shaft 31 is horizontally rotatable between the two mounting seats 30, and a connecting seat 32 is fixedly mounted on the rotating shaft 31. The lower U-shaped plate 33 is mounted on the connecting seat 32 with its opening facing upwards. The upper U-shaped plate 40 is vertically slidably mounted on the upper part of the mounting frame 10 on the side away from the tunnel inner wall with its opening facing downwards. The top of the decorative panel 20 is inserted into the upper U-shaped plate 40, and the bottom is inserted into the lower U-shaped plate 33. During installation, the connecting seat 32 and the lower U-shaped plate 33 are first slightly rotated outwards to allow sufficient space for the lower part of the decorative panel 20 to be inserted. Then, the lower part of the decorative panel 20 is inserted into the lower U-shaped plate 33 to complete the initial positioning. Next, the decorative panel 20 is pushed towards the mounting frame 10. At this time, the decorative panel 20 will cause the lower U-shaped plate 33 and the connecting seat 32 to rotate inward around the axis of the rotating shaft 31, gradually bringing the decorative panel 20 closer to the mounting frame 10. Then, the upper U-shaped plate 40 is adjusted to slide vertically downwards along the mounting frame 10, allowing it to engage with the top of the decorative panel 20, thus fixing both ends of the decorative panel 20. The fixing component 50 is set on the upper U-shaped plate 40 and is used to fix the upper U-shaped plate 40 to the mounting frame 10 when the decorative panel 20 is engaged with the upper U-shaped plate 40 and the lower U-shaped plate 33, thereby ensuring that the overall installation of the decorative panel 20 is firm, stable, and reliable. Installation is relatively convenient, reducing installation time and the labor intensity of workers.

[0031] Specifically, the mounting frame 10 has two vertically spaced connecting plates 70, and two horizontally spaced connecting columns 71 on the connecting plates 70. A fixing plate 72 is located on the side of the connecting columns 71 away from the connecting plates 70. The fixing plate 72 has four mounting holes 73 arranged in a rectangular array, which connect to expansion bolts pre-installed on the tunnel sidewall. The mounting frame 10 has two spaced-apart sliding grooves 11, within which slide blocks 12 connected to the upper U-shaped plate 40 slide, ensuring the stability of the upper U-shaped plate 40's sliding motion. Two first cones 34 are horizontally spaced within the lower U-shaped plate 33. A first connecting hole is provided at the bottom of the mounting frame 10 corresponding to the first cones 34. Two second cones 41 are horizontally spaced within the upper U-shaped plate 40. A second connecting hole is provided at the top of the mounting frame 10 corresponding to the second cones 41. When the decorative plate 20 mates with the lower U-shaped plate 33, the first cones 34 are inserted into the first connecting holes. When the decorative plate 20 mates with the upper U-shaped plate 40, the second cones 41 are inserted into the second connecting holes. The first cones 34 and second cones 41 restrict the position of the decorative plate 20 along the length of the lower U-shaped plate 33.

[0032] During setup, the fixing assembly 50 includes horizontally spaced upright plates 51 on the upper U-shaped plate 40, with the line connecting the two upright plates 51 perpendicular to the length direction of the upper U-shaped plate 40. Each upright plate 51 has horizontally opening sliding holes, and a sliding rod 52 is slidably mounted within both holes. The mounting frame 10 has fixing holes; when the end of the sliding rod 52 is placed in the fixing holes, it fixes the positions of the upright plates 51 and the upper U-shaped plate 40. A retaining ring 53 is fixedly fitted onto the rod 52 located between the two upright plates 51. A compression spring 54 is fitted onto the rod 52 located between the retaining ring 53 and the upright plate 51 furthest from the mounting frame 10. One end of the compression spring 54 is connected to the retaining ring 53, and the other end is connected to the upright plate 51 furthest from the mounting frame 10. A handle 55 is provided at the end of the sliding rod 52 furthest from the mounting frame 10. The compression spring 54 provides elastic force to the retaining ring 53 and the sliding rod 52 towards the mounting frame 10, ensuring that the end of the sliding rod 52 is stably inserted into the fixing holes in the fixed state.

[0033] In the specific setup, a torsion spring is fitted on the rotating shaft 31. One end of the torsion spring is connected to the mounting base 30, and the other end is connected to the connecting base 32. The torsion spring provides elastic force for the connecting base 32 to rotate away from the mounting frame 10. When the decorative panel 20 needs to be replaced, the upper U-shaped plate 40 is slid upward, and the torsion spring provides elastic force to make the connecting base 32 and the lower U-shaped plate 33 rotate away from the mounting frame 10, which makes it easy for the staff to remove the decorative panel 20 from the lower U-shaped plate 33. The mounting base 30 has a horizontally formed circular hole, and the rotating shaft 31 is rotatably connected to the circular hole. The mounting base 30 also has an arc-shaped groove 60, which communicates with the circular hole. A limiting block 61 connected to the rotating shaft 31 is slidably disposed in the arc-shaped groove 60. When the rotating shaft 31 rotates, it drives the limiting block 61 to slide in the arc-shaped groove 60. The arc-shaped groove 60 restricts the sliding of the limiting block 61, thereby limiting the rotation angle of the rotating shaft 31, and thus limiting the rotation angle of the connecting base 32 and the lower U-shaped plate 33.

[0034] The operating principle of the tunnel sidewall decorative panel structure in this embodiment is as follows: During installation, the connecting seat 32 and the lower U-shaped plate 33 are first slightly rotated outwards. Then, the lower part of the decorative panel 20 is inserted into the lower U-shaped plate 33, ensuring that the first cone 34 mates with the first connecting hole. Next, the decorative panel 20 is pushed towards the mounting frame 10. At this time, the decorative panel 20 will drive the lower U-shaped plate 33 and the connecting seat 32 to rotate inwards around the axis of the rotating shaft 31, so that the decorative panel 20 gradually approaches the mounting frame 10. Then, the upper U-shaped plate 40 is adjusted to slide vertically downwards along the mounting frame 10, so that it is inserted into the top of the decorative panel 20, and the second cone 41 mates with the second connecting hole, thereby fixing the upper and lower ends of the decorative panel 20. At this time, the fixing hole and the sliding rod 52 are concentric. The compression spring 54 releases thrust to push the retaining ring 53 and the sliding rod 52 to move. The sliding rod 52 is inserted into the fixing hole, so that the position of the upright plate 51 and the upper U-shaped plate 40 is fixed, thereby ensuring that the decorative panel 20 is installed firmly, stably and reliably.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
