Description
Technical Field
[0001] This utility model relates to the technical field of transmission interface modules, and in particular to a network audio and video transmission interface module. Background Technology
[0002] A networked audio / video transmission interface module is an electronic device module specifically designed for efficient and stable transmission of audio and video signals in a network environment. It is typically integrated as a key component into various devices that require audio and video transmission.
[0003] Currently, network audio and video transmission interfaces are usually exposed to the air for extended periods. For various devices, the exposed interfaces are relatively fixed and obvious in appearance and location. Device manufacturers do not need to design interface access methods for special protection, and devices of different brands and models can be easily adapted, improving versatility.
[0004] While exposing network audio and video transmission interfaces to air can improve versatility, prolonged exposure exposes the interfaces to the external environment, making them susceptible to physical damage such as impacts and scratches. Furthermore, in high-humidity environments, the metal parts of the interface are prone to rust and corrosion; and with significant temperature fluctuations, the interface material's performance changes due to thermal expansion and contraction, affecting connection tightness and signal transmission quality. Therefore, a network audio and video transmission interface module is proposed to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a network audio and video transmission interface module, which aims to improve the problem that the transmission interface cannot be effectively protected in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A network audio and video transmission interface module includes a housing, with multiple dustproof components provided on the inner side of one end of the housing, cooling components provided on the inner sides of both ends of the housing, and two mounting components provided on the outer sides of both ends of the housing. A fixing block is fixedly connected to the inner side of the housing, and multiple sliding grooves are provided on the inner side of the fixing block. Each of the multiple sliding grooves is provided with a snap-fit component.
[0008] The dustproof assembly includes a dustproof cover plate, which is rotatably connected to the inner side of the end of the housing. A sealing ring is fixedly connected to the inner side of the dustproof cover plate. A transmission interface is installed on the inner side of the end of the housing, and the sealing ring is disposed on the outer side of the transmission interface.
[0009] As a further description of the above technical solution:
[0010] The cooling component includes a fan housing, which is fixedly connected to the inner side of the outer shell. Multiple filters are fixedly connected to the inner side of the end of the fan housing, and multiple brackets are fixedly connected to the inner side of the outer shell. Fan assemblies are installed on the inner side of each of the multiple brackets.
[0011] As a further description of the above technical solution:
[0012] The snap-fit assembly includes a slider that is slidably connected to the inner side of the slide groove. A spring is sleeved on the outer side of the slider, with one end of the spring installed inside the fixing block and the other end of the spring installed outside the end of the spring.
[0013] As a further description of the above technical solution:
[0014] The mounting assembly includes a connecting block, which is fixedly connected to the outside of the housing. A snap-fit block is slidably connected to the inside of the connecting block, and fixing bolts are installed on the inner sides of both ends of the snap-fit block.
[0015] As a further description of the above technical solution:
[0016] A dust-absorbing cotton is fixedly connected to the outer side of the end of the fan casing, and the dust-absorbing cotton is also fixedly connected to the inner side of the end of the outer casing.
[0017] As a further description of the above technical solution:
[0018] Multiple heat sinks are fixedly connected to the inner side of the outer casing, and two ventilation openings are provided on the inner sides of both ends of the outer casing.

[0021] As a further description of the above technical solution:
[0022] Pull rings are installed on the outer side of each of the aforementioned dust covers.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, a dustproof cover provides reliable dust protection for the transmission interface. When the dustproof cover is closed, the inner sealing ring fits tightly against the outer side of the transmission interface, effectively preventing dust and debris from entering the interface. This avoids problems such as poor interface contact and transmission failure caused by dust accumulation, extends the service life of the transmission interface, and ensures the stability and reliability of audio and video transmission.
[0025] 2. In this invention, the fan assembly draws external air into the module, which is then filtered by a filter and a dust-absorbing cotton to remove internal heat and expel it through a vent. Simultaneously, the heat sink increases the heat dissipation area and improves heat dissipation efficiency, effectively reducing the internal temperature of the module and preventing problems such as performance degradation and shortened lifespan of electronic components due to overheating. This ensures the stability and reliability of the module during long-term operation. Attached Figure Description

[0035] 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.
[0036] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a network audio and video transmission interface module, including a shell 1, a plurality of dustproof components are provided on the inner side of the end of the shell 1, cooling components are provided on the inner side of both ends of the shell 1, two mounting components are provided on the outer side of both ends of the shell 1, a fixing block 10 is fixedly connected to the inner side of the shell 1, a plurality of sliding grooves 19 are opened on the inner side of the fixing block 10, and a snap-fit component is provided on the inner side of the plurality of sliding grooves 19.
[0037] The dustproof assembly includes a dust cover 4, which is rotatably connected to the inner side of the end of the housing 1. A sealing ring 11 is fixedly connected to the inner side of the dust cover 4. A transmission interface 6 is installed on the inner side of the end of the housing 1, and the sealing ring 11 is located on the outer side of the transmission interface 6. When the transmission interface 6 is not in use, the sealing ring 11 on the inner side of the dust cover 4 tightly fits against the outer side of the transmission interface 6, forming a sealed protective space, effectively preventing dust from entering the transmission interface 6 and avoiding poor contact or transmission failure due to dust accumulation. Pull rings 5 are installed on the outer sides of multiple dust covers 4. By pulling the pull rings 5, the dust cover 4 is opened around the rotation axis, exposing the transmission interface 6 for convenient equipment connection operations.
[0038] Reference Figure 1 and Figure 5 The cooling component includes a fan housing 7, which is fixedly connected to the inside of the outer casing 1. Multiple filters 13 are fixedly connected to the inner side of the fan housing 7 at its end, filtering out larger dust particles from the air. Multiple brackets 14 are fixedly connected to the inside of the outer casing 1, and fan assemblies 15 are installed on the inner side of each bracket 14. The fan assemblies 15 start operating. The suction generated by the fan operation forces outside air into the module through a vent 8 at one end of the outer casing 1. A dust-absorbing cotton 16 is fixedly connected to the outer side of the end of the fan housing 7, and is also fixedly connected to the inner side of the end of the outer casing 1. The air then continues to pass through the dust-absorbing cotton 16 on the outer side of the end of the fan housing 7, where it further absorbs fine dust particles, ensuring that the air entering the module is clean. Multiple heat sinks 9 are fixedly connected to the inside of the outer casing 1. The heat sinks 9 have a large surface area, enabling them to quickly absorb heat generated by the electronic components inside the module and transfer the heat to the flowing air. Two vents 8 are opened on the inner sides of both ends of the outer casing 1. The air that has absorbed heat is exhausted outside the module through the vent 8 at the other end of the outer casing 1.
[0039] Reference Figure 2 , Figure 6 and Figure 7 The snap-fit assembly includes a slider 17, which is slidably connected to the inner side of a groove 19. A spring 20 is sleeved on the outer side of the slider 17, with one end of the spring 20 mounted on the inner side of a fixing block 10 and the other end of the spring 20 mounted on the outer side of its end. Multiple locking rings 18 are fixedly connected to the outer sides of the ends of multiple sliders 17, and multiple locking rings 18 are also mounted on the outer sides of the ends of multiple springs 20. When a wire needs to be snapped in, the wire is aligned with the groove 19 on the fixing block 10 and inserted. During insertion, the wire compresses the slider 17, causing it to slide towards the spring 20 within the groove 19. Simultaneously, the spring 20 is compressed, generating elastic potential energy. Once the wire is fully inserted, the spring 20, due to its elastic restoring force, pushes the slider 17 to slide in the opposite direction. The locking rings 18 on the outer side of the slider 17 tightly hold the wire, firmly fixing it to the fixing block 10.
[0040] Reference Figure 1 and Figure 4 The mounting assembly includes a connecting block 2, which is fixedly connected to the outside of the housing 1. A snap-fit block 3 is slidably connected to the inside of the connecting block 2, and fixing bolts 12 are installed on the inner sides of both ends of the snap-fit block 3. The position of the snap-fit block 3 within the connecting block 2 is adjusted to align with the pre-drilled holes or slots at the mounting location. Then, the fixing bolts 12 are passed through the mounting holes on the inner sides of both ends of the snap-fit block 3 to securely connect the snap-fit block 3 to the target device, thereby firmly mounting the entire module onto the target device.
[0041] Working principle: First, install the module in the designated position, adjust the position of the snap-fit block 3 to match the corresponding structure of the snap-fit block 3, and then fix the snap-fit block 3 with the fixing bolt 12, thereby stably installing the entire module in the required position.
[0042] When internal wiring of a module needs to be placed in an orderly manner into the fixed block 10, the wiring will press against the slider 17, causing the slider 17 to slide within the groove 19 and compress the spring 20. After the wiring is installed in place, the elasticity of the spring 20 causes the slider 17 to return to its original position. The retaining ring 18 then clamps and secures the wiring, ensuring its neatness and stability within the module.
[0043] When the module's transmission interface 6 is not in use, the dust cover 4 will be closed, and the sealing ring 11 can effectively prevent dust from entering the area of the transmission interface 6. When the transmission interface 6 needs to be used, the dust cover 4 can be pulled open around the pivot point by the pull ring 5, exposing the transmission interface 6 for easy connection of audio and video equipment.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
