Description

Technical Field

[0001] This application relates to the field of baking oven equipment technology, and specifically discloses a spliced ​​anti-fall sound barrier. Background Technology

[0002] With the acceleration of urbanization, traffic noise pollution has become an increasingly prominent problem, and sound barriers have been widely used as a major noise reduction facility. However, traditional sound barriers have the following problems in design and installation:

[0003] Low installation efficiency: Existing sound barriers mostly use bolt fixing or welding connection, which requires one-to-one hole positioning or professional welding equipment, resulting in long construction cycle and high cost; there is a lack of standardized interfaces between splicing units, making it difficult to achieve rapid modular assembly.

[0004] Insufficient stability: Traditional sound barriers are prone to overall displacement or even collapse when subjected to wind, vibration or accidental impact, especially on elevated bridges or slopes, posing a risk of falling and threatening the safety of vehicles or pedestrians below.

[0005] Poor adjustability: When the ground is uneven or the required installation height changes, the existing sound barriers lack a flexible height adjustment mechanism, requiring the customization of support structures of different specifications, resulting in a waste of resources.

[0006] Maintenance difficulties: When a part is damaged, a large section of the structure needs to be removed and replaced, which is costly and affects the overall use.

[0007] Therefore, the inventors have provided a spliced ​​anti-fall sound barrier to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to solve the problems of existing anti-fall sound barriers being inconvenient to install and having low stability.

[0009] To achieve the above objectives, the basic solution of this utility model provides a spliced ​​anti-fall sound barrier, including a support rod sleeved at the bottom of the sound barrier, rolling balls symmetrically arranged at both ends of the support rod, limiting blocks symmetrically arranged at both ends of the corresponding rolling balls for limiting the rolling balls, and a plurality of fixing structures arranged on the limiting blocks for fixing and splicing the limiting blocks on the same side. The rolling balls are placed in the limiting blocks after being spliced. Each limiting block is provided with a limiting structure and an anti-fall structure. The limiting structure includes a trapezoidal block for limiting the rolling balls, a guide rod fixed to the trapezoidal block and vertically slidably connected to the limiting block, and a telescopic spring rod arranged on the guide rod. The anti-fall structure is a rolling groove arranged in the limiting block for the rolling balls and a section of the support rod to extend into and rotate. The trapezoidal block is used to clamp the rolling balls and prevent the rolling balls from sliding and rotating in the rolling groove when the sound barrier is not under force. A height adjustment component can also be detachably connected to the bottom of the limiting block.

[0010] Furthermore, the fixing structure includes threaded holes at the four corners of the corresponding limiting block and threaded holes that can extend into the limiting block on the same side and fix the limiting block on the same side.

[0011] Furthermore, the height adjustment component is a scissor-type telescopic frame with both ends hinged to the spliced ​​limiting block, and a fixed base plate located at the bottom of the scissor-type telescopic frame for sliding at the other end of the scissor-type telescopic frame.

[0012] Furthermore, the fixed base plate is provided with guide slides for sliding at both ends of the bottom of the scissor-type telescopic frame, and the fixed base plate is also provided with second fixing members at both ends.

[0013] Furthermore, the second fastener consists of a fixing hole on the fixing base plate and an expansion bolt that can extend into the fixing hole and connect to the ground.

[0014] Furthermore, the clamping ends of the trapezoidal blocks are all provided with anti-slip pads.

[0015] The principle and effect of this basic scheme are as follows:

[0016] 1. Dual anti-fall mechanism for high safety:

[0017] Normal locking: The trapezoidal block clamps the rolling ball under the action of the telescopic spring rod, and combined with the frictional resistance of the anti-slip pad, it ensures that the sound barrier is stably fixed when there is no external force.

[0018] Dynamic buffering: When subjected to strong winds or impacts, the external force overcomes the spring pressure, causing the trapezoidal block to retract, and the rolling ball slides through the rolling groove and rotates. The rotation disperses the impact energy, preventing the structure from breaking. After the impact disappears, the rolling ball is reset.

[0019] Anti-detachment design: The arc-shaped structure of the rolling groove limits the rotation range of the rolling ball, while the end of the support rod is embedded in the groove. Even if the spring fails, the rolling ball is still constrained by the groove wall, preventing it from completely detaching and causing the sound barrier to fall.

[0020] 2. Modular assembly:

[0021] The limit block adopts a standardized interface design, which can be installed by matching the screw through the four corner threaded holes, without the need for complicated positioning;

[0022] 3. Height is flexible and adjustable, with strong terrain adaptability:

[0023] The scissor-type telescopic frame can achieve a height change of 200-500mm by adjusting the unfolding angle, and with the stepless sliding of the guide rail, it can adapt to complex terrains such as slopes and steps;

[0024] The base plate is anchored to the ground with expansion bolts to ensure overall stability after adjustment. Attached Figure Description

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0029] The reference numerals in the accompanying drawings of the instruction manual include: 1. sound barrier; 2. support rod; 3. rolling ball; 4. limit block; 5. threaded hole; 6. guide rod; 7. telescopic spring rod; 8. trapezoidal block; 9. rolling groove; 10. expansion bolt; 11. scissor-type telescopic frame; and 12. fixed base plate.

[0030] A modular sound barrier designed to prevent falls, for example... Figure 1 , Figure 2 As shown:

[0031] The system includes a support rod 2 fitted onto the bottom of the sound barrier 1, rolling balls 3 symmetrically fixed at both ends of the support rod 2, and limiting blocks 4 symmetrically installed at both ends of the corresponding rolling balls 3 for limiting their movement. There are two limiting blocks 4 on the same side. The system also includes multiple fixing structures on the limiting blocks 4 for fixing and splicing them together. The fixing structures include threaded holes 5 at the four corners of the corresponding limiting blocks 4, and threaded holes 5 extending into the threaded holes 5 to fix the limiting blocks 4 together.

[0032] The rolling ball 3 is installed on the limiting block 4 after being assembled with the limiting block 4. The limiting block 4 is equipped with a limiting structure and an anti-fall structure. The limiting structure includes trapezoidal blocks 8 symmetrically installed at the upper and lower ends of a single limiting block 4 for limiting the rolling ball 3. The inclined edge of the trapezoidal block 8 contacts the surface of the rolling ball 3. The clamping end of the trapezoidal block 8 is equipped with an anti-slip pad. It also includes a guide rod 6 fixedly connected to the trapezoidal block 8 and vertically slidably connected to the limiting block 4, and a telescopic spring rod 7 installed on the guide rod 6. The anti-fall structure is a rolling groove 9 set in the limiting block 4 for the rolling ball 3 and a section of the support rod 2 to extend into and rotate. When the rolling ball 3 presses the trapezoidal block 8 with great force, the trapezoidal block 8 moves upward and cannot block the rolling groove 9, so that the rolling ball 3 and a section of the support rod 2 extend into the rolling groove 9 to rotate, thereby buffering the rotation and preventing the sound barrier 1 from falling under great force.

[0033] The trapezoidal block 8 is used to clamp the rolling ball 3 when the sound barrier 1 is not under force and to prevent the rolling ball 3 from sliding and rotating in the rolling groove 9. The bottom of the limiting block 4 can also be detachably connected to a height adjustment component.

[0034] The height adjustment component consists of a scissor-type telescopic frame 11, with both ends hinged to the spliced ​​limiting block 4, and a fixed base plate 12 installed at the bottom of the scissor-type telescopic frame 11 for sliding at the other end. The fixed base plate 12 is equipped with guide rails for sliding at both ends of the bottom of the scissor-type telescopic frame 11. Second fixing components are also provided at both ends of the fixed base plate 12. The second fixing components are fixing holes formed in the fixed base plate 12 and expansion bolts 10 that can extend into the fixing holes and connect to the ground.

[0035] The uses of this utility model are as follows:

[0036] Assembly and installation: Fit the support rod 2 onto the bottom of the sound barrier 1, embed the rolling ball 3 into the limiting block 4 on the same side, and lock the threaded holes 5 at the four corners of the adjacent limiting blocks 4 with screws;

[0037] Anti-fall function: The trapezoidal block 8 clamps the rolling ball 3 under the action of the telescopic spring rod 7. When an external force impacts, the rolling ball 3 pushes the trapezoidal block 8 and slides into the rolling groove 9. The rolling ball 3 rolls and rotates to buffer the external force and prevent the sound barrier 1 from falling. After the buffering is completed, the telescopic spring rod 7 is pulled to reset the sound barrier 1 and the rolling ball 3.

[0038] Height adjustment: Adjust the unfolding angle of the scissor telescopic frame 11, slide the bottom along the guide rail, and fix the fixed base plate 12 to the ground by the expansion bolts 10;

[0039] Maintenance and replacement: The damaged limit block 4 or support rod 2 module can be replaced by disassembling the screw.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
