[0002] Audio and video receiving devices refer to equipment or systems used to receive, decode, and play audio and video signals. They are widely used in home entertainment, conference systems, broadcasting and television, security monitoring and other fields. Nowadays, audio and video receiving devices are also indispensable in video conferencing.

[0003] When using an audio receiving device, data transmission or power supply requires the use of data cables or power cables. However, during use, staff may accidentally pull on the cables, which can easily cause the connection points to become loose and affect the use of the device.

[0004] In view of this, we propose a noise-reducing and interference-resistant audio and video receiving device for conferences. Utility Model Content

[0005] The purpose of this invention is to provide a noise-reducing and interference-resistant conference audio and video receiving device, which solves the problem that cables are easily pulled loose, affecting connection stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A triangular block is fixedly connected to the surface of the connecting seat. A plug is fixedly connected to the surface of the triangular block.

[0011] Preferably, a sliding ring is slidably connected to the inner side of the protective sleeve, and a rotating ring is rotatably connected to the inner side of the sliding ring.

[0012] Preferably, a toggle block is fixedly connected to the surface of the rotating ring, and a fitting block is fixedly connected to the side of the rotating ring away from the toggle block, with a limit hole formed on the surface of the fitting block.

[0013] Preferably, the gaps between the interlocking blocks and the triangular blocks are interlocked, and the number of protective sleeves is two sets, with the two sets of protective sleeves symmetrically arranged about the center line of the protective box as the axis of symmetry.

[0014] Preferably, the fixing component includes a slider, which is fixedly connected to the surface of the sliding ring.

[0017] By employing the above technical solution, this utility model provides a noise-reducing and interference-resistant conference audio and video receiving device. It possesses at least the following beneficial effects:

[0018] 1. This utility model pushes the actuating block, causing the actuating block to drive the sliding ring towards the triangular block via the rotating ring. While the rotating ring is moving, the actuating block can also be twisted to rotate the rotating ring to a certain extent, so that the fitting block gradually embeds itself between the triangular blocks. The insert rod on the surface of the triangular block will be inserted into the limiting hole opened on the surface of the fitting block, so that the triangular block and the fitting block are completely fitted to form a closed loop to tighten the connecting wire. This prevents the connecting wire from becoming loose when the device body is pulled by external force during use, thus affecting the use of the device body.

[0019] 2. When the push block is pushed and the sliding ring is moved, the sliding piece on the side of the sliding ring will slide along the sliding groove and gradually contact the inclined surface of the hook, thereby forcing the hook to rotate. When the hook completely exceeds the locking hole, the torsion spring will drive the hook to reset and lock the sliding piece to prevent the sliding ring from resetting, thus ensuring the stability of the protective component when tightening the wire harness.

[0027] 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.

[0028] A noise-reducing and interference-resistant audio and video receiving device for conferences, such as Figures 1-5As shown, the device includes a device body 1 and a receiver 5. A hinge 4 is threaded through and hinged to the inner side of the device body 1. The hinge 4 passes through the receiver 5 and is fixedly connected to the receiver 5. A connection cable insertion hole 6 is provided on the surface of the device body 1. The outer shell of the device body 1 is made of anti-interference material. The device also includes a protective component 2, which is used to prevent the connection cable from loosening when the device body 1 is inserted. A fixing component 3 is used to provide protection and reinforcement when the connection cable is connected in conjunction with the protective component 2. The protective component 2 includes a protective box 21, which is fixedly connected to the surface of the device body 1. A fixing plate 22 is fixedly connected to the inner side of the protective box 21. A sliding plate 23 is slidably connected to the surface of the fixing plate 22. A spring 24 is fixedly connected between the sliding plate 23 and the fixing plate 22. A protective sleeve 25 is fixedly connected to the surface of the sliding plate 23. A connecting seat 26 is fixedly connected to the inner side of the protective sleeve 25. A triangular block 27 is fixedly connected to the surface of the connecting seat 26. A plug rod 28 is fixedly connected to the surface of the triangular block 27. A sliding ring 29 is slidably connected to the inner side of the protective sleeve 25, and a rotating ring 210 is rotatably connected to the inner side of the sliding ring 29. Pulling the symmetrical protective sleeve 25 will cause the symmetrical protective sleeve 25 to tightly bind the connecting wire. At this time, the actuating block 211 can be pushed, so that the actuating block 211 drives the sliding ring 29 to move towards the triangular block 27 through the rotating ring 210. When the rotating ring 210 moves, the actuating block 211 can also be twisted to make the rotating ring 210 rotate to a certain extent. A toggle block 211 is fixedly connected to the surface of the rotating ring 210. A fitting block 212 is fixedly connected to the side of the rotating ring 210 away from the toggle block 211. A limiting hole 213 is formed on the surface of the fitting block 212. When the rotating ring 210 moves, the toggle block 211 can be twisted to make the rotating ring 210 rotate to a certain extent, so that the fitting block 212 gradually embeds into the triangular blocks 27. The insertion rod 28 on the surface of the triangular block 27 will be inserted into the limiting hole 213 formed on the surface of the fitting block 212, so that the triangular block 27 and the fitting block 212 are completely fitted to form a closed loop to tighten the connecting wire. The gap between the fitting block 212 and the triangular block 27 is fitted. There are two sets of protective sleeves 25, and the two sets of protective sleeves 25 are symmetrically arranged with the center line of the protective box 21 as the axis of symmetry.

[0029] The fixing component 3 includes a slider 31, which is fixedly connected to the surface of the sliding ring 29. A locking hole 32 is formed on the surface of the slider 31, and a groove 33 is formed on the surface of the protective sleeve 25. The slider 31 passes through the groove 33 and is slidably connected to the protective sleeve 25. A hinge block 34 is fixedly connected to the surface of the protective box 21. A hook 35 is hinged to the inner side of the hinge block 34. When the actuating block 211 is pushed and the sliding ring 29 is moved, the slider 31 on the side of the sliding ring 29 slides along the groove 33, and gradually contacts the inclined surface of the hook 35, thus forcing the hook 35 to rotate. The hook 35 is aligned with the locking hole 32. A torsion spring 36 is fixedly connected between the hinge block 34 and the hook 35. When the hook 35 completely exceeds the locking hole 32, the torsion spring 36 will cause the hook 35 to reset and lock the slider 31 to prevent the sliding ring 29 from resetting, ensuring the stability of the protective component 2 when tightening the wire harness.

[0030] When using the noise reduction and anti-interference conference audio and video receiving device of this utility model, the symmetrically arranged protective sleeves 25 are first in an open state. At this time, the connecting wires can be inserted into the connecting wire sockets 6. Then, multiple sets of connecting wires are manually bundled together. Then, the symmetrical protective sleeves 25 are pulled to make the symmetrical protective sleeves 25 tightly bundle the connecting wires. At this time, the toggle block 211 can be pushed, so that the toggle block 211 drives the sliding ring 29 to move towards the triangular block 27 through the rotating ring 210. When the rotating ring 210 moves, the toggle block 211 can also be twisted to make the rotating ring 210 rotate to a certain extent, so that the fitting block 212 gradually embeds into the triangular block 27. The insertion rod 28 on the surface of the triangular block 27 will be inserted into the limiting hole 213 opened on the surface of the fitting block 212, so that the triangular block 27 and the fitting block 212 are completely fitted to form a closed loop to tightly bundle the connecting wires. This prevents the connecting wires from becoming loose when the device body 1 is pulled by external force during use, which would affect the use of the device body 1.

[0031] When the push block 211 is pushed and the sliding ring 29 is moved, the sliding piece 31 on the side of the sliding ring 29 will slide along the sliding groove 33, and the sliding piece 31 will gradually contact the inclined surface of the hook 35, thereby forcing the hook 35 to rotate. When the hook 35 completely exceeds the locking hole 32, the torsion spring 36 will drive the hook 35 to reset and lock the sliding piece 31 to prevent the sliding ring 29 from resetting, thus ensuring the stability of the protective component 2 when tightening the wire harness.
