[0002] With the continuous development of society and the improvement of people's living standards, cultural and entertainment programs are becoming increasingly abundant, and there are more and more events and performances being held. Setting up a stage is an essential part of holding performances. Setting up a stage requires the use of many electrical devices, lighting and sound equipment. Correspondingly, these electrical devices require a large number of wires to connect to the power supply. These wires are usually placed randomly on the ground, which not only easily damages the wires but also hinders the work of on-site staff. Therefore, wire protection devices are often used to protect the wires during or after the stage is set up.

[0003] Patent publication number CN218352063U discloses a lighting and audio cable protection device, including a base and a top cover, as well as a mounting plate and suction cups. The base has an isosceles trapezoidal cross-section, with a smooth arc surface at the connection between the long side wall and the bottom, and a groove at the connection. A cable trough is provided at the top of the base, and a mounting groove is provided at the bottom. One end of the top cover is mounted on the top side of the cable trough via a pivot. A partition is provided inside the cable trough. The mounting plate is bolted into the mounting groove. Several sets of suction cups are evenly arranged at the bottom. This utility model can adhere to the ground or wall to prevent displacement, thus effectively gathering the cables, and is convenient for installation and recycling, effectively improving the use effect of the cable protection device. However, in the above device, the top cover is only hinged to the top of the cable trough, making the connection between the top cover and the cable trough not secure enough. When the device is placed on the ground, the top cover is not tight and can easily be kicked open by passers-by, causing the cables to be exposed or even tangled, posing a safety hazard. Utility Model Content

[0004] To address the issue that the top cover of the aforementioned device is merely hinged to the top of the cable tray, resulting in an insufficiently secure connection between the top cover and the cable tray, and the top cover being loose when the device is placed on the ground, making it easy for passersby to kick it open, exposing the wires or even causing them to become tangled, thus posing a safety hazard, this utility model provides an audio cable shielding and protection device.

[0005] This utility model provides a shielding and protection device for audio cables, which adopts the following technical solution:

[0006] An audio cable shielding and protection device includes a protective shell, a wire groove is provided inside the protective shell, a cover plate is installed on the top of the protective shell, and a locking mechanism is provided between the cover plate and the protective shell.

[0007] The locking mechanism includes two sets of fixing plates, which are respectively installed at both ends of the top of the cover plate.

[0017] Optionally, a positioning mechanism is provided at the bottom of the cover plate and the top of the protective shell. The positioning mechanism includes two sets of positioning blocks, which are respectively installed at both ends of the top of the protective shell. Positioning grooves that are inserted and cooperate with the positioning blocks are provided at both ends of the bottom of the cover plate.

[0018] By adopting the above technical solution, the positioning block and positioning groove are inserted and matched to perform preliminary positioning when connecting the protective shell and the cover plate, so that the protective shell and the cover plate fit better after connection.

[0019] Optionally, a connecting mechanism is provided between adjacent cover plates. The connecting mechanism includes a connecting block, which is installed at the rear end of the cover plate. A first magnet is connected to the end of the connecting block away from the cover plate. A connecting groove is provided at the front end of the cover plate to engage with the connecting block. A second magnet is connected to the inner wall of the connecting groove. The first magnet and the second magnet are magnetically connected.

[0020] By adopting the above technical solution, the connecting block is inserted into the corresponding connecting slot, so that the first magnet and the second magnet are magnetically connected, thereby enabling multiple cover plates to be spliced ​​together, so that the device can protect wires of different lengths.

[0021] Optionally, the internal connection of the cable tray includes several partitions.

[0022] By adopting the above technical solution, it is convenient to separate the wires by using several partitions, thus minimizing the possibility of the wires getting tangled.

[0023] In summary, this utility model has at least one of the following beneficial effects:

[0024] The combination of the hand-held part, movable rod, fixed plate, positioning spring, connecting plate, snap-fit ​​part and movable plate makes the connection between the cover and the protective shell more secure, preventing the cover from being easily kicked open by passers-by and causing the wires to be exposed.

[0025] By using the combination of the first magnet, the connecting block, the second magnet, and the connecting slot, the connecting block is inserted into the corresponding connecting slot, so that the first magnet and the second magnet are magnetically connected, thereby enabling multiple cover plates to be spliced ​​together, and thus enabling the device to protect wires of different lengths.

[0032] The following is combined with Figure 1-3 The present invention will be described in further detail below.

[0033] Please refer to the attached diagram in the instruction manual. Figure 1 This utility model provides an embodiment of an audio cable shielding and protection device, including a protective shell 2. The protective shell 2 has a cable groove 5 inside, and the inner wall of the cable groove 5 is connected to a layer of tin foil 7. This shields the electromagnetic field generated when the cable is energized within the cable core, reducing electromagnetic interference to the outside world and limiting the influence of external electromagnetic fields on the internal signals of the cable. Several partitions 6 are fixedly connected inside the cable groove 5. These partitions facilitate the separation of the cable and minimize the possibility of tangling between the cables.

[0034] Please refer to the attached diagram in the instruction manual. Figure 1 Rubber seats 4 are fixedly installed at the four corners of the bottom of the protective shell 2, and fixing mechanisms 3 are provided on both sides of the protective shell 2 near the rubber seats 4. The rubber seats 4 are in direct contact with the ground, which increases the friction between the protective shell 2 and the ground, making the protective shell 2 more stable when placed.

[0035] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 The fixing mechanism 3 includes four sets of connecting seats 302, which are installed at one end of the protective shell 2 near the rubber seat 4. Each of the four sets of connecting seats 302 has a screw 303 screwed into its middle. A rotating wheel 301 is installed on the top of each of the four sets of screws 303, and a suction cup 304 is installed on the bottom of each of the four sets of screws 303. Rotating the rotating wheel 301 causes the screw 303 to rotate, which in turn causes the suction cup 304 to rotate and move downwards, allowing the suction cup 304 to adhere to the ground and further fix the protective shell 2.

[0036] Please refer to the attached diagram in the instruction manual. Figure 1 A cover plate 9 is installed on the top of the protective shell 2. A positioning mechanism 1 is provided at the bottom of the cover plate 9 and the top of the protective shell 2. The positioning mechanism 1 includes two sets of positioning blocks 101, which are fixedly installed at both ends of the top of the protective shell 2. Positioning grooves 102 are provided at both ends of the bottom of the cover plate 9 to engage with the positioning blocks 101. Through the engagement of the positioning blocks 101 and the positioning grooves 102, the protective shell 2 and the cover plate 9 can be initially positioned when connected, so that the protective shell 2 and the cover plate 9 fit more snugly after connection.

[0037] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 A connecting mechanism 8 is provided between adjacent cover plates 9. The connecting mechanism 8 includes a connecting block 802, which is fixedly installed at the rear end of the cover plate 9. A first magnet 801 is fixedly connected to the end of the connecting block 802 away from the cover plate 9. A connecting groove 804 is opened at the front end of the cover plate 9 to engage with the connecting block 802. A second magnet 803 is fixedly connected to the inner wall of the connecting groove 804. The first magnet 801 and the second magnet 803 are magnetically connected. By inserting the connecting block 802 into the corresponding connecting groove 804, the first magnet 801 and the second magnet 803 are magnetically connected, thereby enabling multiple cover plates 9 to be spliced ​​together, allowing the device to protect wires of different lengths.

[0038] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 3A locking mechanism 10 is provided between the cover plate 9 and the protective shell 2. The locking mechanism 10 includes two sets of fixing plates 1003, which are respectively installed at both ends of the top of the cover plate 9. A movable rod 1002 is slidably passed through the middle of the fixing plate 1003. A handhold 1001 is installed on the side of the movable rod 1002 near the center of the cover plate 9. A connecting plate 1005 is installed on the end of the movable rod 1002 away from the handhold 1001. A positioning spring 1004 is sleeved on the outer wall of the movable rod 1002, and the positioning spring 1004 is located between the fixing plate 1003 and the connecting plate 1005. A movable plate 1007 is installed at the bottom of the connecting plate 1005. A snap-fit ​​part 1006 is provided between the movable plate 1007 and the protective shell 2. The snap-fit ​​part 1006 includes a snap block 10062, which is installed on the inner side of the movable plate 1007. A slot 10061 matching the snap block 10062 is opened on the outer side of the protective shell 2. The insertion and engagement of the slot 10061 and the block 10062 make the connection between the movable plate 1007 and the protective shell 2 more secure, further improving the stability of the connection between the cover plate 9 and the protective shell 2.

[0039] Working principle: When in use, the rubber base 4 is in direct contact with the ground. Then, the operator rotates the rotating wheel 301. The rotation of the rotating wheel 301 drives the screw 303 to rotate. The rotation of the screw 303 drives the suction cup 304 to rotate and move downward, so that the suction cup 304 is attached to the ground, thereby fixing the protective shell 2. Due to the action of the suction cup 304, when the protective shell 2 is kicked by the staff, the displacement can be effectively reduced.

[0040] Then, the lighting and audio cables are sorted and placed into the cable tray 5. Next, the operator pulls the two sets of handheld parts 1001 to move them apart. The movement of the handheld parts 1001 drives the locking part 1006 to move via the movable rod 1002, which compresses the positioning spring 1004. When the connecting plate 1005 moves, it drives the movable plate 1007 to move. Then, through the cooperation of the positioning block 101 and the positioning groove 102, the cover plate 9 is closed on the top of the protective shell 2. At this time, the handheld parts 1001 are released. Under the elastic force of the positioning spring 1004, the movable plate 1007 adheres to both sides of the protective shell 2 and drives the locking block 10062 to be inserted into the inside of the locking groove 10061, making the connection between the cover plate 9 and the protective shell 2 more secure. This completes the protection of the lighting and audio cables and prevents the cover plate 9 from being easily kicked open by passersby, thus exposing the cables.

[0041] When the device needs to be spliced, the connecting block 802 is inserted into the corresponding connecting slot 804, so that the first magnet 801 and the second magnet 803 are magnetically connected, thereby enabling multiple cover plates 9 to be spliced ​​together. This allows the device to protect wires of different lengths and improves the practicality of the device.

[0042] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
