Description

Technical Field

[0001] This utility model relates to the field of sound barrier technology, specifically a foldable and portable emergency sound barrier. Background Technology

[0002] A sound barrier is a facility that reduces noise propagation by blocking, reflecting, absorbing, or scattering sound waves through physical barriers and acoustic treatments. It utilizes acoustic principles and material properties to intervene in the sound propagation path between the noise source and the receiver, reducing the transfer of noise energy. It protects specific areas from noise pollution, thereby improving the acoustic environment, enhancing people's quality of life, and also contributing to ecological protection and a better city image.

[0003] When assembling a sound barrier, after connecting the bottom sound insulation panel to the column, the transparent screen and the top sound insulation panel need to be hoisted using a hoisting tool. Because the sound insulation panel and the transparent screen need to be positioned during hoisting, the assembly time is increased. When the sound barrier is needed for emergency use, it cannot be installed in time, making the sound barrier inconvenient to install and disassemble, and thus having defects when used in emergency situations. Utility Model Content

[0004] The purpose of this invention is to provide a foldable and portable emergency sound barrier to solve the problems mentioned in the background art, which require repeated positioning during the hoisting of the sound barrier, thus increasing the hoisting time during assembly, making it impossible to complete the installation quickly, and making it inconvenient to load and unload during use, thus causing defects in emergency use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable and portable emergency sound barrier, comprising a sound insulation panel and a frame, wherein a screen body is provided inside the frame, and a connecting component for assembly is provided outside the sound insulation panel and the frame, the connecting component including sliders provided on both sides of the outer wall of the frame, the outer wall of the sliders being provided with multiple protrusions, one end of the sound insulation panel being provided with a groove, and the inner wall of the groove being provided with a damping pad;

[0006] Mounting plates are provided on both sides of the slide. The mounting plates have slots and cavities inside. A lead screw and a spring are provided inside the slots. A collar is provided outside the lead screw. A connecting rod is provided on the outer wall of the collar. A locking block is provided inside the cavity.

[0007] Preferably, the screen is embedded in the frame, the two ends of the frame are connected to the ends of the sound insulation board, one end of the slider is connected to the outside of the frame, and the other end extends into the groove outside the sound insulation board and is slidably connected to the inside of the groove.

[0008] Preferably, the plurality of protrusions are all arc-shaped structures and are arrayed on both sides of the slider. The damping pad is embedded and connected to the inner wall of the groove. When the slider slides in the groove, the protrusions on the outer wall abut against the damping pad.

[0009] Preferably, the mounting plate is located on the outer wall of the inlet end of the slide and is integrally formed with the outer wall of the sound insulation plate. The inner wall of the slot in the mounting plate communicates with the cavity, and the cavity communicates with the slide.

[0010] Preferably, the lead screw is located in the slot and is rotatably connected to the inner wall of the slot, and there is a damping sensation when the lead screw rotates. The collar is sleeved on the outside of the lead screw and slides and extends with the inner wall of the slot, and the texture of the inner wall of the collar corresponds to the lead screw.

[0011] Preferably, the locking block is located inside the cavity, and the connecting rod is rotatably connected to the inner wall of the mounting plate via a fixed shaft. The two ends of the connecting rod extend into the cavity and the slot, respectively, and are rotatably connected to the collar and the locking block via bearings.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The transparent screen is installed using a frame, and the frame and sound insulation panel are designed as separate structures. During installation, the sound insulation panel and frame can be slidably installed using a slider and a sliding groove. The sliding assembly method can quickly achieve positioning and facilitate docking assembly. At the same time, the protrusion on the outside of the slider abuts against the damping pad on the inner wall of the sliding groove when it slides and connects with the groove, thereby reducing gaps in the groove, improving the airtightness of the sliding connection, and ensuring the sound insulation effect during sliding assembly.

[0014] 2. After the sound insulation panel is slidably assembled with the frame of the mounting screen, the protrusion in the outer mounting plate of the sound insulation panel drives the locking block away from the slide groove, thereby ensuring that the frame can be smoothly slidably assembled. After the sliding connection, the locking block in the mounting plate locks the slider and the slide groove, thereby ensuring that the sound insulation panel and the frame are fixed after assembly. This is used for locking operations to ensure a tight connection and prevent noise leakage. In addition, the locking by the insert block makes it easier to install and remove, improving the efficiency of installation and removal. At the same time, the split design can improve the portability of the sound barrier.

[0015] This invention changes the sound barrier's screen body and sound insulation panel into a separate structure, making it easy to disassemble, fold, and carry. The screen body and sound insulation panel are assembled by sliding, improving the efficiency of positioning and loading / unloading during assembly, and facilitating rapid assembly and use in emergency situations.

[0021] 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.

[0022] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0023] Please see the appendix Figure 1-3 As shown, the foldable and portable emergency sound barrier includes a soundproof panel 1 and a frame 2. A screen 201 is housed inside the frame 2, which is used to install the screen 201. The frame 2 facilitates the assembly of the screen 201 with the soundproof panel 1. Connecting components for assembly are provided on the exterior of the soundproof panel 1 and the frame 2. These connecting components include sliders 3 located on both sides of the outer wall of the frame 2. The sliders 3 assist in positioning the mating angle of the soundproof panel 1 and the frame 2 during assembly, improving positioning efficiency. 3 can be embedded in the groove 4 at one end of the sound insulation board 1, so that the sound insulation board 1 and the frame 2 can be slidably assembled. The outer wall of the slider 3 is provided with multiple protrusions 301. The protrusions 301 are arc-shaped and can abut against the damping pad 401 on the inner wall of the groove 4. Since the damping pad 401 is a flexible material, it can squeeze the slider 3 in the groove 4, reduce the gap in the groove 4, improve the sealing after sliding assembly, and ensure the sound insulation effect. The sound insulation board 1 is provided with a groove 4 at one end, and the inner wall of the groove 4 is provided with a damping pad 401.

[0024] The screen 201 is embedded in the frame 2. The two ends of the frame 2 are connected to the ends of the sound insulation board 1. One end of the slider 3 is connected to the outside of the frame 2, and the other end extends into the groove 4 outside the sound insulation board 1 and is slidably connected to the inside of the groove 4. Multiple protrusions 301 are all arc-shaped structures and are arrayed on both sides of the slider 3. The damping pad 401 is embedded in the inner wall of the groove 4. When the slider 3 slides in the groove 4, the protrusions 301 on the outer wall abut against the damping pad 401.

[0025] In this embodiment: When installing the sound barrier, the sliders 3 at both ends of the frame 2 are embedded into the grooves 4 in the upper and lower sound insulation plates 1 and slide in the grooves 4. The combination of the grooves 4 and the sliders 3 can assist in positioning during the assembly of the sound barrier, thereby guiding the angle during assembly. When the sliders 3 are embedded in the grooves 4, the protrusions 301 on the outside of the sliders 3 abut against the damping pads 401 on the inner wall of the grooves 4. The toughness of the damping pads 401 can squeeze the sliders 3 in the grooves 4, thereby ensuring the sealing of the joint gap after sliding connection and ensuring the sound insulation effect.

[0026] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 2-4 Mounting plates 5 are provided on both sides of the slide groove 4. The mounting plates 5 have slots 501 and cavities 8 inside. The slots 501 and cavities 8 can respectively house the collar 601 and the locking block 9 and guide and position their sliding angles. The slots 501 are provided with lead screws 6 and springs 602. The lead screw 6 passes through the collar 601 and is connected to the outer wall texture. When rotating, it can drive the collar 601 to slide and extend within the slots 501. At the same time, in the normal state, the springs 602 support the collar 601. The collar 601 is provided outside the lead screw 6. The outer wall of the collar 601 is provided with connecting rods 7. The two ends of the connecting rods 7 are connected to the collar 601 and the locking block 9 respectively, so that the collar 601 and the locking block 9 are linked. The locking block 9 is provided inside the cavity 8.

[0027] Mounting plate 5 is located on the outer wall of the inlet end of the slide 4 and is integrally formed with the outer wall of the sound insulation plate 1. The inner wall of the slot 501 in the mounting plate 5 is connected to the cavity 8, and the cavity 8 is connected to the slide 4. The lead screw 6 is located in the slot 501 and is rotatably connected to the inner wall of the slot 501. The lead screw 6 has a damping feel when it rotates. The collar 601 is sleeved on the outside of the lead screw 6 and slides and extends with the inner wall of the slot 501. The texture of the inner wall of the collar 601 corresponds to the lead screw 6. The locking block 9 is located in the cavity 8, and the connecting rod 7 is rotatably connected to the inner wall of the mounting plate 5 through a fixed shaft. The two ends of the connecting rod 7 extend into the cavity 8 and the slot 501 respectively, and are rotatably connected to the collar 601 and the locking block 9 respectively through bearings.

[0028] In this embodiment: Before the slider 3 of the frame 2 slides and assembles in the groove 4 within the sound insulation panel 1, the screw 6 is first rotated by a tool, and the collar 601 slides and retracts into the slot 501 in conjunction with the texture. At the same time, the locking block 9 retracts into the cavity 8 and moves away from the groove 4 through the connecting rod 7, allowing the slider 3 to slide smoothly in the groove 4. After sliding to the designated position, the screw 6 is reversed again, causing the collar 601 to slide and extend outward from the slot 501. At the same time, the locking block 9 slides outward from the cavity 8 into the groove 4 in conjunction with the connecting rod 7, and embeds itself inside the slider 3, thereby locking the position of the slider 3 in the groove 4. This allows the sound insulation panel 1 and the screen 201 to slide and assemble into a sound barrier. The assembled sound barrier is then placed between two support columns, which lock and support the installation position of the sound barrier. In addition, multiple sound barrier arrays can be assembled in conjunction with the support columns.
