Description

Technical Field

[0001] This utility model relates to the field of municipal construction, and in particular to a sound insulation board fixing structure for municipal construction. Background Technology

[0002] In municipal construction, with the rapid development of urban transportation, traffic noise pollution has become a significant factor affecting residents' quality of life and the quality of the urban environment. To effectively reduce noise interference, municipal sound barriers, as a commonly used noise reduction facility, are widely applied along roads, overpasses, and other transportation routes. Their performance and installation efficiency directly affect the effectiveness of urban noise control and the cost of engineering construction.

[0003] Currently, the installation of traditional municipal soundproof panels generally uses bolt fixing or slot splicing methods. When using bolt fixing, construction workers need to precisely drill holes in the soundproof panel and the supporting structure, and then tighten the bolts one by one. The installation process is cumbersome and difficult to align, resulting in low construction efficiency and making it difficult to meet the tight schedule of municipal projects. While slot splicing is relatively convenient, gaps are prone to appear at the joints, making it impossible to achieve a seamless fit. This allows external sound waves to easily propagate through the gaps, reducing the sound insulation effect. In addition, the existing soundproof panel installation structure often lacks a flexible adjustment mechanism, making it difficult to adapt to the terrain undulations and noise propagation directions of different road sections. When encountering external forces such as strong winds and vehicle vibrations, the soundproof panels are prone to displacement or tilting, which not only affects the noise reduction performance but also significantly increases the later maintenance costs.

[0004] In response to this technical problem, this application proposes a fixing structure for sound insulation panels used in municipal buildings. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixing structure for sound insulation panels used in municipal construction. In municipal construction, this utility model achieves rapid and precise installation of sound insulation panels through a combination of rivets and limiting rods, shortening the construction cycle. By utilizing a rotating rod and ratchet pawl structure, the height and angle of the support rod can be flexibly adjusted and securely locked, ensuring sound insulation performance and reducing maintenance costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fixing structure for sound insulation panels used in municipal buildings includes a plate and a connecting seat. A connecting block is fixedly connected to the rear side of the plate, and a support rod is rotatably connected to the lower side of the connecting block. A lifting component is installed inside the support rod, and a fixing component is installed inside the right side of the plate. A second support rod is slidably connected inside the first support rod, and a connecting seat is rotatably connected to the bottom end of the second support rod. A bolt is installed inside the connecting seat, and a washer is sleeved on the outer wall of the bolt. A nut is threadedly connected to the lower side of the bolt.

[0008] Furthermore, the lifting assembly includes a rotating rod rotatably connected inside the support rod, a wheel is fixedly connected to the right side of the rotating rod, a fixed shaft is fixedly connected to the right side of the wheel, a gear is fixedly connected to the right side of the fixed shaft, and the wheel is rotatably connected inside the support rod.

[0009] Furthermore, the fixing assembly includes a rivet disposed inside the plate, an adjusting shaft slidably connected inside the rivet, a limit rod rotatably connected inside the lower side of the rivet, a limit ring fixedly connected to the lower side of the adjusting shaft, and a spring sleeved on the lower outer wall of the adjusting shaft.

[0010] Furthermore, a claw is fixedly connected to the rear side of the wheel, and an auxiliary block is rotatably connected inside the support rod.

[0011] Furthermore, a rack column is fixedly connected to the upper side of the second support rod, and the rack column is meshed with the left side of the gear.

[0012] Furthermore, a pull ring is rotatably connected to the upper side of the rivet.

[0013] Furthermore, the rivet has a thread on its upper side, an auxiliary ring is threadedly connected to the upper side of the outer wall of the rivet, and an auxiliary rod is fixedly connected to the outer wall of the auxiliary ring.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the combination design of rivets and limiting rods in municipal construction greatly improves the installation efficiency of sound insulation panels. The limiting rods construct a precise positioning frame, allowing construction workers to quickly embed the sound insulation panels along the limiting grooves to complete the initial positioning, significantly reducing the alignment time during installation. Combined with the fastening effect of high-strength rivets, not only can a rigid connection of the sound insulation panels be achieved, ensuring a seamless fit at the joints and effectively blocking external sound waves such as traffic noise, but it can also adapt to the tight schedule of municipal engineering projects, significantly shortening the construction cycle of sound barriers.

[0016] 2. This utility model, based on the structure of a rotating rod, ratchet, and pawl, provides a highly flexible adjustment solution for the installation of municipal sound insulation panels. Construction workers can easily control the height and angle of the support rod by rotating the rotating rod, precisely adapting to the terrain undulations and noise propagation directions of different road sections. The self-locking function of the pawl securely locks the support rod after adjustment, maintaining structural stability even in the face of external forces such as strong winds and vehicle vibrations, preventing the sound insulation panel from shifting or tilting. This ensures the continuity of the sound insulation effect, reduces subsequent maintenance costs, and enhances the practicality and durability of municipal sound insulation facilities.

[0023] 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.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a sound insulation board fixing structure for municipal buildings, comprising a plate 1 and a connecting seat 6. A connecting block 2 is fixedly connected to the rear side of the plate 1. A support rod 4 is rotatably connected to the lower side of the connecting block 2. A rotating rod 19 is provided inside the support rod 4. A wheel 15 is fixedly connected to the right side of the rotating rod 19. A fixed shaft is fixedly connected to the right side of the wheel 15. A gear 16 is fixedly connected to the right side of the fixed shaft. The wheel 15 is rotatably connected inside the support rod 4. A rivet 10 is provided inside the right side of the plate 1. An adjusting shaft 7 is slidably connected inside the rivet 10. A limit rod 11 is rotatably connected to the lower side of the rivet 10. A limit ring 8 is fixedly connected to the lower side of the adjusting shaft 7. A spring 9 is sleeved on the lower outer wall of the adjusting shaft 7. A support rod 5 is slidably connected inside the support rod 4. A connecting seat 6 is rotatably connected to the bottom end of the support rod 5. A bolt 20 is provided inside the connecting seat 6. A washer 22 is sleeved on the outer wall of the bolt 20. A nut 21 is threadedly connected to the lower side of the bolt 20.

[0025] Specifically, during the use of the device, the two plates 1 can be placed flat together, and the pre-drilled holes can be installed. Rivets 10 can be inserted. Due to the internal spring 9, the limiting ring 8 will be pushed upwards. The limiting rod 11 has a small support foot between the limiting rings 8, so pushing the limiting ring 8 upwards will cause the limiting rod 11 to warp. This does not affect the insertion process. After insertion, rotate the auxiliary ring 12. With continuous tightening, the auxiliary ring 12 will be close to one side of the plate 1, and the warped limiting rod 11 will be fixed on the other side. The self-locking performance of the threaded connection will prevent the device from falling off. When it needs to be removed, the auxiliary ring 12 can be rotated. When the device is loose, the adjusting shaft 7 can be pressed to make the limiting ring 8 move downwards. The limiting ring 8 will push the limiting rod 11. The limiting rod 11 will rotate along the middle and be close to the inner arm of the rivet 10. It can be removed from the hole connecting the two plates 1, and the plate 1 can be replaced. When the angle of the device needs to be adjusted, the rotating rod 19 can be rotated. The rotating rod 19 will drive the wheel 15 on one side to rotate, thereby driving the gear 16 to rotate. The gear 16 will mesh with the rack column 14 on the upper side of the support rod 2 5, allowing the device to move up and down inside the support rod 1 4, thereby extending the support frame of the device to adapt to different terrains. In this process, the claw 17 can restrict the rotation of the wheel 15, giving the device a good self-locking performance. The auxiliary block 18 on the lower side is equipped with a spring 9 that can pull the claw 17, so that the claw 17 will not rotate randomly and can always be locked on the side of the wheel 15. When it is necessary to store the device, the claw 17 left on the outside can be pressed to lift the claw 17. Without the restriction of the claw 17, the wheel 15 can rotate freely, thereby storing the device.

[0026] Reference Figure 4 A pawl 17 is fixedly connected to the rear side of the cam 15, and an auxiliary block 18 is rotatably connected inside the support rod 4. A rack column 14 is fixedly connected to the upper side of the support rod 5, and the rack column 14 is meshed with the left side of the gear 16. The rivet 10 has threads on its upper side, and an auxiliary ring 12 is threadedly connected to the upper side of the outer wall of the rivet 10. An auxiliary rod 13 is fixedly connected to the outer wall of the auxiliary ring 12. A pull ring 3 is rotatably connected to the upper side of the rivet 10.

[0027] Specifically, a claw 17 is fixedly connected to the rear side of the wheel 15 to limit its rotation and achieve the self-locking function of the device. An auxiliary block 18 is rotatably connected inside the support rod 1 4. A spring 9 is installed inside the auxiliary block 18, which can pull the claw 17 to stably lock it on the side of the wheel 15 and prevent it from rotating randomly. A rack column 14 is fixedly connected to the upper side of the support rod 2 5. The rack column 14 meshes with the left side of the gear 16. When the rotating rod 19 drives the wheel 15 and the gear 16 to rotate, the meshing transmission between the gear 16 and the rack column 14 enables the support rod 2 5 to move up and down inside the support rod 1 4, thereby adjusting the height of the device support frame to adapt to different terrains. The rivet 10 has threads on its upper side, and an auxiliary ring 12 is connected to its upper outer wall by threads. An auxiliary rod 13 is fixedly connected to the outer wall of the auxiliary ring 12 to facilitate the rotation of the auxiliary ring 12. When installing the sound insulation panel, rotating the auxiliary ring 12 allows it to fit tightly against one side of the panel 1, while the limiting rod 11 secures the other side. For removal, rotating the auxiliary ring 12 in the opposite direction loosens the connection. Furthermore, a pull ring 3 is rotatably connected to the upper side of the rivet 10, facilitating insertion and removal of the rivet 10 and improving the ease of installation and disassembly of the device.

[0028] Working principle:

[0029] When two plates 1 need to be joined, align the pre-drilled holes in the plates 1 and insert the rivets 10. Due to the pre-tightening force of the spring 9, the limiting ring 8 is pushed upward, causing the outer end of the limiting rod 11 to tilt upward, forming a barb structure. At this time, rotate the auxiliary ring 12, and gradually press the surface of the plates 1 by utilizing its threaded engagement with the rivets 10. The barb of the limiting rod 11 forms a reverse pulling force on the other side, and the two plates 1 are firmly connected through thread self-locking. For disassembly, first rotate the auxiliary ring 12 in the opposite direction to release the clamping force, and then press the adjusting shaft 7 to move the limiting ring 8 downward. The limiting ring 8 pushes the limiting rod 11 inward, making it close to the inner wall of the rivet 10, and the rivet 10 can be easily pulled out to complete the disassembly. No tools are required, and a single person can operate quickly.

[0030] When the rotating rod 19 is rotated, the ratchet wheel 15 and gear 16 are synchronously driven to rotate via the fixed shaft. The meshing transmission between gear 16 and rack column 14 causes support rod 2 5 to extend and retract within support rod 1 4, realizing height adjustment of the device to adapt to different terrains. The one-way ratchet structure of ratchet wheel 15 cooperates with ratchet pawl 17 to prevent reverse rotation during rotation, ensuring the stability of the adjusted angle. Spring 9 in auxiliary block 18 continuously provides tension, keeping ratchet pawl 17 always engaged with ratchet wheel 15. Even under external vibration or load changes, ratchet pawl 17 can immediately engage with the teeth of ratchet wheel 15, preventing the angle from changing on its own. When storing, press the outer ratchet pawl 17 to disengage it, and the support rod can be retracted freely.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
