Description

Technical Field

[0001] This utility model relates to the technical field of sound barrier unit panels, and in particular to a snap-on sound barrier unit panel. Background Technology

[0002] As a key device for controlling noise pollution in traffic arteries (such as highways and railways) and industrial areas, the core component of a sound barrier is the sound barrier unit panel. The stability of the connection between the unit panel and the supporting structure, the ease of installation, and the efficiency of subsequent maintenance directly determine the overall noise reduction performance and service life of the sound barrier.

[0003] According to the utility model patent authorized by the State Intellectual Property Office with the number CN206971103U, a flexible fixing structure for sound barrier unit panels is disclosed. This structure sets shock-absorbing strips and elastic elements (including a first snap-fit ​​part, an abutment part, and a second snap-fit ​​part) in the gap between the H-shaped steel column and the unit panel. The abutment force of the elastic element is used to press the unit panel and the shock-absorbing strip together to achieve flexible fixing, which improves the buffering defects of traditional rigid connections to a certain extent.

[0004] However, this patent and the current mainstream plug-in installation method still have many technical pain points that restrict engineering applications: high risk of falling off. The existing plug-in installation relies entirely on the depth of the unit plate inserted into the H-beam to prevent falling off. If the insertion depth is insufficient during construction, or if it is subjected to external forces such as long-term vibration and strong wind impact during operation, the unit plate is prone to sinking, displacement or even falling off, which not only destroys the noise reduction effect, but may also fall onto traffic lines and cause safety hazards.

[0005] Therefore, we propose a snap-fit ​​sound barrier unit panel. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a snap-on sound barrier unit panel.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A snap-fit ​​sound barrier unit panel includes an I-beam, with insertion slots on both sides of the I-beam. Locking hard connection structures are fixed inside the two insertion slots and on both sides. Insertion connection structures are provided between two adjacent locking hard connection structures. The sound barrier unit panel body is provided inside the two insertion connection structures.

[0009] The I-beam has two locking mechanisms on its front and back sidewalls. These two locking mechanisms are used to lock the I-beam, the locking hard connection structure, and the plug-in connection structure.

[0010] I-beams serve as the core load-bearing component of the overall structure, providing stable support for each component; the plug-in slots on both sides can precisely accommodate the locking hard connection structure, ensuring the accuracy of its installation position; adjacent locking hard connection structures can form bidirectional limit on the plug-in connection structure, preventing its lateral displacement; the plug-in connection structure provides installation space for the sound barrier unit panel body, realizing the initial assembly of the unit panel body and the overall frame, laying the foundation for the subsequent locking steps.

[0011] As a preferred embodiment of this utility model, the locking hard connection structure includes a fixing member, the fixing member having a connecting groove inside, and a first locking hole having a center inside the fixing member.

[0012] By setting a locking mechanism on the front and back of the I-beam, the relative positions of the I-beam, the locking rigid connection structure, and the plug-in connection structure can be directly fixed, preventing relative displacement of the three components due to vibration, wind, or other factors during use, and significantly improving the overall structural stability.

[0013] As a preferred embodiment of this utility model, the fastener is welded to the I-beam, and the first locking hole penetrates through the main body of the fastener.

[0014] The fastener serves as the main frame of the locking hard connection structure, providing a load-bearing foundation for the connecting groove and the first locking hole; the connecting groove can be matched with the corresponding part of the plug-in connection structure to achieve the initial positioning of the two; the first locking hole provides an insertion channel for the core component of the locking mechanism, preparing the structure for subsequent multi-structure linkage locking.

[0015] As a preferred embodiment of the present invention, the plug-in connection structure includes a plug-in connector, the plug-in connector having an installation groove inside, and splicing adapter grooves being provided inside the plug-in connector and on both sides of the installation groove. Second locking holes are provided on both side walls of the plug-in connector.

[0016] The plug-in connector serves as the core carrier of the plug-in connection structure, providing the installation foundation for the mounting slot, splicing adapter slot, and second locking hole. The mounting slot can precisely accommodate the sound barrier unit panel body, enabling stable assembly of the unit panel body and the plug-in connector. The splicing adapter slot can tightly fit with the corresponding part of the locking hard connection structure, improving the fit between the two. The second locking hole corresponds to the position of the first locking hole, providing a complete insertion path for the locking mechanism and ensuring the locking function is realized.

[0017] As a preferred embodiment of this utility model, the plug-in connector is installed between two locking hard connection structures, the second locking hole penetrates the side wall of the plug-in connector and communicates with the interior of the splicing adapter groove, and the interior of the mounting groove is fixedly connected to the sound barrier unit plate body.

[0018] The plug-in connector is installed between two locking hard connection structures, which can laterally limit its movement and prevent it from shifting. The second locking hole penetrates the side wall and connects to the splicing adapter slot, ensuring that the locking components of the locking mechanism can pass through the plug-in connector and the locking hard connection structure in sequence to achieve linkage locking between the two. The mounting slot is fixedly connected to the sound barrier unit panel body, so that the unit panel body and the plug-in connector form an integrated structure and prevent the unit panel body from loosening.

[0019] As a preferred embodiment of this utility model, the locking mechanism includes a mounting housing, a locking rod inside the mounting housing, a mounting sliding plate at the connection of the locking rod, two guide rails on the inner wall of the mounting housing, two guide sliders on the outer wall of the mounting sliding plate, a connecting rod at the connection of the mounting sliding plate, a cover plate on the outer wall of the mounting housing, a support spring between the cover plate and the mounting sliding plate and on the outer wall of the connecting rod, and a pull ring at the connection of the connecting rod and on the outer side of the cover plate.

[0020] The mounting housing provides a closed installation space for the internal components of the locking mechanism, preventing them from being affected by external dust and rain. The locking rod is the core component for locking, used to insert into various structural holes. The mounting slide plate can drive the locking rod to move synchronously, realizing the switching between locking and unlocking. The guide rail and guide slider cooperate to provide precise guidance for the movement of the mounting slide plate, preventing jamming and deviation. The connecting rod is used to transmit the external force of the pull ring to the mounting slide plate. The cover plate can close the mounting housing to protect the internal components. The support spring can provide a reset force for the mounting slide plate, ensuring that the locking rod remains locked when there is no external force. The pull ring allows the operator to apply external force to realize the unlocking operation.

[0021] As a preferred embodiment of this utility model, the mounting housing is fixedly installed on the outer wall of the I-beam, the cover plate is fixedly installed at the mounting housing, and the locking rod passes through the I-beam and connects to the first locking hole and the second locking hole, thereby realizing the locking of the locking hard connection structure, the plug-in connection structure and the sound barrier unit panel body.

[0022] The mounting housing is fixed to the outer wall of the I-beam, ensuring that the locking mechanism is relatively fixed to the I-beam, providing a stable foundation for locking operations. The cover plate is fixed to the mounting housing to ensure the internal sealing of the mounting housing and prevent internal components from falling off or being corroded. The locking rod passes through the I-beam and connects to the first locking hole and the second locking hole, which can tightly connect the I-beam, the locking hard connection structure, and the plug-in connection structure, thereby indirectly locking the sound barrier unit panel body through the plug-in connection structure, achieving a stable connection of the overall structure.

[0023] As a preferred embodiment of this utility model, when the pulling ring is pulled, the mounting sliding plate is moved by the connecting rod. When the mounting sliding plate moves, it is guided by the guide slider at the guide rail and squeezes the support spring. At the same time, it drives the locking rod to move and disengage from the first locking hole and the second locking hole.

[0024] When the pull ring is pulled, the external force can be effectively transmitted to the mounting sliding plate through the connecting rod, driving it to move. During the movement of the mounting sliding plate, the guide slider slides along the guide rail to ensure accurate movement direction and avoid the mounting sliding plate from deviating or getting stuck. At the same time, the mounting sliding plate compresses the support spring, allowing the spring to store reset potential energy. The mounting sliding plate synchronously drives the locking rod to move, causing it to disengage from the first locking hole and the second locking hole, quickly unlocking the locking mechanism and facilitating the disassembly, maintenance, or adjustment of the subsequent structure.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] In this invention, a collaborative locking system is formed by the locking rigid connection structure on both sides of the I-beam, the plug-in connection structure, and the locking mechanism. The fixing parts of the locking rigid connection structure are welded to the I-beam, providing rigid support for the overall connection. The plug-in connector of the plug-in connection structure is adapted to the sound barrier unit panel body, realizing precise docking between the unit panel and the support structure. Finally, the locking rod of the locking mechanism passes through the first locking hole of the I-beam, the fixing part, and the second locking hole of the plug-in connector to complete the multi-node forced locking. This design completely eliminates the dependence on "insertion depth" of traditional plug-in installation. Even without additional insertion depth redundancy, mechanical locking can prevent the unit panel from shifting, effectively avoiding the problem of unit panel detachment caused by vibration and strong wind during operation, and significantly improving the overall structural safety of the sound barrier.

[0038] Example

[0039] like Figure 1-6 As shown, this utility model provides a technical solution: a snap-fit ​​sound barrier unit panel, including an I-beam 10, with insertion slots 20 on both sides of the I-beam 10, and a locking hard connection structure 30 fixed inside the two insertion slots 20 and located on both sides, and a plug-in connection structure 40 between two adjacent locking hard connection structures 30, with a sound barrier unit panel body 50 inside the two plug-in connection structures 40; two locking mechanisms 60 are provided on the front and back side walls of the I-beam 10, and the two locking mechanisms 60 are used to lock the I-beam 10, the locking hard connection structure 30 and the plug-in connection structure 40.

[0040] During assembly, the locking rigid connection structure 30 is first fixed in the insertion slot 20 of the I-beam 10 to provide rigid support for the connection; then the sound barrier unit panel body 50 is installed into the mounting slot 402 of the insertion connection structure 40 to form a combination; then the combination is placed between two adjacent locking rigid connection structures 30 to achieve preliminary docking; finally, the locking mechanisms 60 on the front and back sides of the I-beam 10 are used to lock the I-beam 10, the locking rigid connection structure 30, and the insertion connection structure 40 to form a whole, ensuring the stable connection of the unit panel and preventing displacement.

[0041] The locking hard connection structure 30 includes a fastener 301, a connecting groove 302 is provided inside the fastener 301, and a first locking hole 303 is provided at the center inside the fastener 301.

[0042] The fastener 301 is fixed by its own structure in conjunction with the insertion slot 20 of the I-beam 10. The internal connecting slot 302 provides space for the insertion or mating of the components of the insertion connection structure 40, so as to realize the docking of the insertion connection structure 40 and the locking hard connection structure 30. The first locking hole 303 at the center provides a through channel for the locking rod 602 of the locking mechanism 60. When the locking rod 602 passes through the hole, the locking hard connection structure 30 can be locked with the I-beam 10 and the insertion connection structure 40, so as to play a role in connection and fixation.

[0043] The fastener 301 is welded to the I-beam 10, and the first locking hole 303 penetrates the main body of the fastener 301.

[0044] The fastener 301 is welded to the I-beam 10 to form a strong rigid connection, ensuring that the locking rigid connection structure 30 does not shift relative to the I-beam 10 when subjected to external force, thus providing stable support for the connection structure. The first locking hole 303 penetrates the main body of the fastener 301, allowing the locking rod 602 of the locking mechanism 60 to pass through from one side of the fastener 301 to the other side, cooperating with other components with locking holes (such as the plug-in connection structure 40) to achieve multi-component locking and ensure connection reliability.

[0045] The plug-in connection structure 40 includes a plug-in connector 401. The plug-in connector 401 has an installation groove 402 inside. The plug-in connector 401 has splicing adapter grooves 403 inside and on both sides of the installation groove 402. The plug-in connector 401 has second locking holes 404 on both side walls.

[0046] The mounting groove 402 of the plug-in connector 401 is used to accommodate and fix the sound barrier unit panel body 50, so that the two form a whole; the splicing adapter grooves 403 on both sides are adapted and spliced ​​with the fasteners 301 and other components of the locking hard connection structure 30 to ensure that the plug-in connection structure 40 is accurately docked and positioned between the two locking hard connection structures 30; the second locking holes 404 on both side walls provide a through channel for the locking rod 602 of the locking mechanism 60. When the locking rod 602 passes through the I-beam 10, the first locking hole 303 and the second locking hole 404 at the same time, the I-beam 10, the locking hard connection structure 30 and the plug-in connection structure 40 can be tightly locked to complete the connection.

[0047] The plug-in connector 401 is installed between two locking hard connection structures 30. The second locking hole 404 penetrates the side wall of the plug-in connector 401 and communicates with the interior of the splicing adapter groove 403. The interior of the mounting groove 402 is fixedly connected to the sound barrier unit panel body 50.

[0048] When the plug-in connector 401 is installed between two locking hard connection structures 30, the splicing adapter grooves 403 on both sides cooperate with the corresponding parts of the locking hard connection structure 30 to achieve initial splicing positioning; the second locking hole 404 penetrates the side wall and communicates with the splicing adapter groove 403, so that after the locking rod 602 of the locking mechanism 60 passes through the I-beam 10, it can smoothly enter the splicing adapter groove 403 and pass through the second locking hole 404, locking the plug-in connector 401 and the locking hard connection structure 30; the mounting groove 402 is fixed to the sound barrier unit panel body 50 to ensure the connection stability between the unit panel body and the plug-in connector 401, so that the unit panel forms a stable whole with the locking hard connection structure 30 and the I-beam 10 through the plug-in connector 401.

[0049] The locking mechanism 60 includes a mounting housing 601, inside which a locking rod 602 is provided. A mounting sliding plate 603 is provided at the connection of the locking rod 602. Two guide rails 604 are also provided on the inner wall of the mounting housing 601. Two guide sliders 605 are provided on the outer wall of the mounting sliding plate 603. A connecting rod 608 is also provided at the connection of the mounting sliding plate 603. A cover plate 607 is also provided on the outer wall of the mounting housing 601. A support spring 606 is also provided between the cover plate 607 and the mounting sliding plate 603 and on the outer wall of the connecting rod 608. A pull ring 609 is provided at the connection of the connecting rod 608 and on the outer side of the cover plate 607.

[0050] The mounting housing 601 provides mounting space and protection for internal components such as the locking rod 602 and the mounting sliding plate 603. When locked, the support spring 606 exerts a spring force on the mounting sliding plate 603, pushing it to move within the mounting housing 601, which in turn moves the locking rod 602 toward the locking holes of the locking rigid connection structure 30 and the plug-in connection structure 40, thus achieving locking. When unlocking, the pull ring 609 on the outer side of the cover plate 607 is pulled, which drives the mounting sliding plate 603 to move via the connecting rod 608. The guide slider 605 on the outer wall of the mounting sliding plate 603 slides along the guide rail 604 on the inner wall of the mounting housing 601, providing guidance and stability. At the same time, the mounting sliding plate 603 compresses the support spring 606, causing the locking rod 602 to exit from the locking hole, thus completing the unlocking.

[0051] The mounting housing 601 is fixedly installed on the outer wall of the I-beam 10, and the cover plate 607 is fixedly installed at the mounting housing 601. The locking rod 602 passes through the I-beam 10 and connects with the first locking hole 303 and the second locking hole 404, thereby realizing the locking of the locking hard connection structure 30, the plug-in connection structure 40 and the sound barrier unit plate body 50.

[0052] The mounting housing 601 is fixed to the outer wall of the I-beam 10, providing a stable mounting base for the locking mechanism 60. The cover plate 607 is fixed to the mounting housing 601, enclosing part of the mounting housing 601 and providing installation and working space for the connecting rod 608, support spring 606, etc. When locked, the locking rod 602 passes through the corresponding position of the I-beam 10 and is inserted into the first locking hole 303 and the second locking hole 404 in sequence, connecting the I-beam 10, the locking hard connection structure 30, and the plug-in connection structure 40. The sound barrier unit panel body 50 is fixed to the plug-in connection structure 40, thereby achieving overall locking of each component, ensuring no relative displacement between components, and improving structural stability.

[0053] When the pull ring 609 is pulled, the mounting sliding plate 603 is moved by the connecting rod 608. When the mounting sliding plate 603 moves, it slides and is guided by the guide slider 605 at the guide rail 604, and squeezes the support spring 606. At the same time, it drives the locking rod 602 to move and disengage from the first locking hole 303 and the second locking hole 404.

[0054] During unlocking or maintenance, pulling the pull ring 609 transmits tension through the connecting rod 608, causing the mounting sliding plate 603 to move within the mounting housing 601. During this movement, the guide slider 605 on the outer wall of the mounting sliding plate 603 slides along the guide rail 604, ensuring the smooth and accurate movement of the mounting sliding plate 603 and preventing deviation. Simultaneously, the mounting sliding plate 603 compresses the support spring 606, causing it to undergo elastic deformation. As the mounting sliding plate 603 moves, the locking rod 602 moves synchronously, gradually disengaging from the first locking hole 303 and the second locking hole 404, thus disengaging the locking rod 602 from the locking hole and completing the unlocking process, facilitating subsequent disassembly or maintenance of the unit board.

[0055] It should be noted that the electrical equipment and components mentioned above are all programmed and controlled using existing PLC controllers. Since these are mature technologies, they will not be described in detail here.

[0056] The working process of this snap-on sound barrier unit panel is as follows:

[0057] I. Assembly Stage

[0058] Fixed locking hard connection structure 30: The fixing member 301 of the locking hard connection structure 30 is welded to the insertion groove 20 on both sides of the I-beam 10, so that the fixing member 301 and the I-beam 10 form a rigid support foundation, providing a stable carrier for subsequent connection.

[0059] Install the sound barrier unit panel body 50: Embed the sound barrier unit panel body 50 into the mounting groove 402 of the plug-in connection structure 40 so that the two form a stable assembly, ensuring the reliability of the connection between the unit panel and the plug-in connector 401.

[0060] The plug-in connection structure 40: The plug-in connection structure 40 with the sound barrier unit plate body 50 is placed between two adjacent locking hard connection structures 30. The splicing adapter groove 403 of the plug-in connector 401 and the connection groove 302 of the locking hard connection structure 30 are used to achieve preliminary docking and positioning, in preparation for subsequent locking.

[0061] II. Lockdown Phase

[0062] The locking mechanism 60 achieves overall fixation through "elastic drive + precise guidance + multi-component through-locking":

[0063] The support spring 606 of the locking mechanism 60 applies a spring force to the mounting sliding plate 603, pushing the mounting sliding plate 603 to move within the mounting housing 601;

[0064] When the sliding plate 603 is moved, the guide slider 605 on its outer wall slides along the guide rail 604 on the inner wall of the mounting housing 601 to ensure that the movement is smooth and precise.

[0065] The sliding plate 603 synchronously drives the locking rod 602 to move towards the locking rigid connection structure 30 and the plug-in connection structure 40, so that the locking rod 602 passes through the I-beam 10, the first locking hole 303 of the locking rigid connection structure 30, and the second locking hole 404 of the plug-in connection structure 40 in sequence, and finally locks the I-beam 10, the locking rigid connection structure 30, the plug-in connection structure 40 and the sound barrier unit panel body 50 into a whole, so as to avoid relative displacement of the components.

[0066] III. Unlocking and Maintenance Phase

[0067] When it is necessary to disassemble or maintain the sound barrier unit panel, unlocking is achieved through "tension transfer + guide sliding + spring compression + locking lever 602 release":

[0068] Pulling the outer pull ring 609 of the locking mechanism 60, the pulling force is transmitted to the mounting sliding plate 603 through the connecting rod 608, causing the mounting sliding plate 603 to move within the mounting housing 601;

[0069] During the movement of the sliding plate 603, the guide slider 605 cooperates with the guide rail 604 to ensure smooth sliding without deviation; at the same time, the sliding plate 603 compresses the support spring 606, causing it to undergo elastic deformation.

[0070] As the sliding plate 603 moves, the locking rod 602 simultaneously exits from the first locking hole 303 and the second locking hole 404, releasing the locking of each component; at this time, the plug-in connection structure 40 and the sound barrier unit plate body 50 can be removed from the locking hard connection structure 30 for replacement or maintenance.

[0071] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
