Description
Technical Field
[0001] This utility model relates to the field of television tuner technology, and in particular to an environmentally friendly television tuner with a biodegradable shell. Background Technology
[0002] The TV tuner is the core component inside a television set used to receive and process wireless television signals. Its main function is to filter out signals of specific channels from the high-frequency signals received by the antenna and convert them into intermediate frequency signals suitable for subsequent circuit processing.
[0003] It is typically used to amplify the received weak high-frequency signals, improve the signal-to-noise ratio, and convert the high-frequency signals into fixed-frequency intermediate-frequency signals (such as the common image intermediate-frequency 38MHz and the audio intermediate-frequency 31.5MHz) to facilitate stable processing by subsequent circuits (such as intermediate-frequency amplifiers and demodulation circuits).
[0004] With increasing environmental awareness and the rapid pace of electronic product upgrades, traditional TV tuner heads, after being discarded, cause long-term environmental pollution due to their non-biodegradable shells and components. Furthermore, in daily use and maintenance, tuner heads are typically secured by screws drilled into corresponding holes on the shell and top cover. While this method ensures a stable connection and guarantees the internal sealing and structural stability of the tuner, preventing external interference from affecting its performance, inspection or maintenance requires the use of screwdrivers and other tools to remove the screws. This process is cumbersome, time-consuming, and repeated screw removal can strip the screw threads, affecting the connection's firmness. Therefore, an environmentally friendly TV tuner with a biodegradable shell is proposed to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an environmentally friendly TV tuner with a biodegradable shell. It aims to solve the problem that, with the increasing awareness of environmental protection and the rapid upgrading of electronic products, the non-biodegradable shell and components of traditional TV tuners will pollute the environment after they are discarded. In daily use and maintenance, screws are often used to fix the shell and top cover. Although the connection is stable and the sealing is good, tools are needed to remove the screws during inspection and maintenance, which is cumbersome and time-consuming. Repeated disassembly can easily strip the screws and affect the firmness.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an environmentally friendly TV tuner with a biodegradable shell, comprising a shell, a C-shaped groove formed on the top of the outer surface of the shell, a C-shaped strip inserted into the inner surface of the C-shaped groove, a sliding cover fixedly connected to the top of the outer surface of the C-shaped strip, the inner surface of the sliding cover slidably connected to the top of the outer surface of the shell, an arc-shaped protrusion fixedly connected to the inner surface of the sliding cover, a groove formed on the top of the outer surface of the shell, the outer surface of the arc-shaped protrusion engaging with the inner surface of the groove, and a connecting component provided on the outer surface of the shell;
[0007] The connecting assembly includes a threaded head, the outer surface of which is fixedly connected to the left side of the outer surface of the housing, and a pin is fixedly connected through and to the left side of the inner surface of the housing.
[0008] As a further description of the above technical solution:
[0009] A limiting frame is fixedly connected to the top of the outer surface of the sliding cover, and a dustproof net is snapped onto the inner surface of the limiting frame.
[0010] As a further description of the above technical solution:
[0011] The top of the outer surface of the sliding cover has heat dissipation holes, and the dustproof mesh is placed above the heat dissipation holes.
[0012] As a further description of the above technical solution:
[0013] The outer surface of the sliding cover is fixedly connected with anti-slip texture.
[0014] As a further description of the above technical solution:
[0015] A frame is fixedly connected to the outer surface of the dustproof net.
[0016] As a further description of the above technical solution:
[0017] Both the outer surface of the outer casing and the sliding cover are chamfered.
[0018] As a further description of the above technical solution:
[0019] The arc-shaped protrusions and grooves are provided in two sets, and are symmetrically distributed at the front and rear ends of the sliding cover and the outer shell.
[0020] As a further description of the above technical solution:
[0021] The limiting frame is set into four groups, and the four groups of limiting frames are arranged in a U-shape.
[0022] As a further description of the above technical solution:
[0023] The anti-slip texture is provided in multiple sets and is evenly and symmetrically arranged on the outer surface of the sliding cover.
[0024] As a further description of the above technical solution:
[0025] Both the arc-shaped protrusion and the groove are designed to be semi-circular.
[0026] This utility model has the following beneficial effects:
[0027] 1. In this utility model, the C-shaped groove and C-shaped strip are inserted to ensure the stability and guiding of the sliding cover. The anti-slip texture on the outside of the sliding cover increases friction, and the arc-shaped protrusion can be disengaged from the groove by simply moving it, allowing for quick removal of the sliding cover without tools, thus improving maintenance efficiency.
[0028] 2. In this utility model, a dustproof net is provided on the heat dissipation hole, and four sets of U-shaped limiting frames are used to precisely fix the biodegradable polylactic acid dustproof net. The dustproof net can be firmly installed by bending it and inserting it into the limiting frame. It flatly covers the heat dissipation hole, blocks foreign objects, protects the components, and does not affect heat dissipation.
[0029] 3. In this utility model, by using biodegradable polylactic acid material for the outer shell, sliding cover and dustproof net, the product can be naturally degraded after disposal, effectively reducing pollution to the ecological environment and meeting current environmental protection needs.

[0036] 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.
[0037] Reference Figure 1 , Figure 2 as well as Figure 4This utility model provides an embodiment of an environmentally friendly TV tuner with a biodegradable shell, comprising a shell 1. A C-shaped groove 11 is formed on the top of the outer surface of the shell 1. The C-shaped groove 11 provides a mounting base for the insertion of a C-shaped strip 10, allowing the sliding cover 3 to form a stable connection structure with the shell 1 via the C-shaped strip 10, ensuring the reliable installation of the sliding cover 3 on the shell 1. A C-shaped strip 10 is inserted into the inner surface of the C-shaped groove 11. The insertion and engagement of the C-shaped strip 10 with the C-shaped groove 11 restricts the horizontal displacement of the sliding cover 3, ensuring that the sliding cover 3 can only slide along a specific direction, improving the stability and guidance of the sliding cover 3 during sliding. The top of the outer surface of the C-shaped strip 10 is fixedly connected to the sliding cover 3. This connection method allows the sliding cover 3 to stably cover the top of the outer shell 1 with the support of the C-shaped strip 10, while also providing a point of leverage for the sliding of the sliding cover 3. The inner surface of the sliding cover 3 is slidably connected to the top of the outer surface of the outer shell 1. The sliding connection design between the sliding cover 3 and the outer shell 1 facilitates the opening and closing of the sliding cover 3. When it is necessary to inspect or maintain the inside of the high-frequency head, the sliding cover 3 can be easily opened, improving the convenience of operation. The inner surface of the sliding cover 3 is fixedly connected with an arc-shaped protrusion 5, and the top of the outer surface of the outer shell 1 is provided with a groove 9. The outer surface of the arc-shaped protrusion 5 engages with the inner surface of the groove 9, so that when the sliding cover 3 is closed, it is firmly fixed to the outer shell 1, ensuring the sealing and safety of the inside of the high-frequency head.
[0038] Reference Figures 1-3 The outer surface of the housing 1 is provided with a connecting component 2. The connecting component 2 enables the high-frequency head to connect with external devices. The connecting component 2 includes a threaded head 201. The outer surface of the threaded head 201 is fixedly connected to the left side of the outer surface of the housing 1. The fixed connection of the threaded head 201 provides a standardized interface for the connection between the high-frequency head and other devices or components. The threaded connection enables quick and secure installation, ensuring the stable connection of the high-frequency head in the entire equipment system. The inner left side of the housing 1 is provided with a pin 202. The pin 202 is an important component for the electrical connection of the high-frequency head. It enables the internal circuit of the high-frequency head to conduct with the external circuit, allowing the high-frequency head to receive and transmit signals. It is a key component for the normal operation of the high-frequency head.
[0039] Reference Figures 1-3A limiting frame 6 is fixedly connected to the top of the outer surface of the sliding cover 3. The fixed connection of the limiting frame 6 provides a limiting structure for the installation of the dustproof net 7, which can accurately position the installation position of the dustproof net 7 and ensure the accuracy and stability of the installation of the dustproof net 7. The dustproof net 7 is snapped into the inner surface of the limiting frame 6, so that the dustproof net 7 can be firmly installed in the limiting frame 6 and prevent the dustproof net 7 from falling off during the use of the high-frequency head. A heat dissipation hole 8 is opened on the top of the outer surface of the sliding cover 3. The opening of the heat dissipation hole 8 can promote the dissipation of heat inside the high-frequency head and prevent the high-frequency head from overheating due to the heat generated by the operation of internal components, which would affect the high frequency. The performance and lifespan of the tuner head ensure the stability of its operation. The dustproof mesh 7 is located above the heat dissipation holes 8. The dustproof mesh 7 can effectively block dust, debris and other foreign objects from entering the tuner head and prevent these foreign objects from damaging the internal components of the tuner head. The outer surface of the sliding cover 3 is fixedly connected with anti-slip texture 4, which allows the user to apply more force when sliding the cover 3 and prevents the hand from slipping. This improves the convenience and safety of opening and closing the sliding cover 3. There are multiple sets of anti-slip texture 4, which are evenly and symmetrically arranged on the outer surface of the sliding cover 3, so that the user can get a stable grip and operating feel no matter from which position the sliding cover 3 is moved.
[0040] Reference Figures 1-3 The outer surface of the dustproof net 7 is fixedly connected to a frame, allowing the dustproof net 7 to be supported by the frame and always maintain a rectangular shape for a more stable fit within the limiting frame 6. The material is polylactic acid (PLA), a biodegradable material that allows the dustproof net 7 to naturally degrade after its service life, preventing long-term environmental pollution. Both the outer surfaces of the outer shell 1 and the sliding cover 3 are chamfered to eliminate sharp edges and reduce the risk of cuts upon contact. Furthermore, the use of PLA material for both the outer shell 1 and the sliding cover 3 ensures the overall durability of the high-frequency head's outer shell 1. The biodegradability further enhances the environmental performance of the high-frequency head, effectively reducing its impact on the ecological environment after product disposal. Both the arc-shaped protrusion 5 and the groove 9 are designed as semi-circles, allowing for smoother engagement and disengagement. Furthermore, the arc-shaped protrusion 5 is made of thermoplastic polyurethane elastomer rubber, which has excellent elasticity and wear resistance. This allows the arc-shaped protrusion 5 to maintain good elastic deformation capacity during engagement and disengagement with the groove 9, extending the service life of the engagement structure and improving the reliability and stability of the engagement.
[0041] Reference Figures 1-3Two sets of arc-shaped protrusions 5 and grooves 9 are provided and symmetrically distributed at the front and rear ends of the sliding cover 3 and the outer shell 1. The two sets of symmetrically distributed arc-shaped protrusions 5 and grooves 9 can provide uniform locking force when the sliding cover 3 is closed, making the connection between the sliding cover 3 and the outer shell 1 more secure and avoiding problems such as the sliding cover 3 shaking or poor sealing due to uneven locking. Four sets of limiting frames 6 are provided and arranged in a U-shape. The four sets of limiting frames 6 arranged in a U-shape can limit and fix the dustproof net 7 from multiple directions, ensuring that the dustproof net 7 remains flat after installation and evenly covers the heat dissipation holes 8, giving full play to the dustproof function of the dustproof net 7.
[0042] Working principle: When the internal workings of the high-frequency head need to be repaired, simply push the anti-slip texture 4 on the sliding cover 3 outward to disengage the arc-shaped protrusion 5 on the sliding cover 3 from the groove 9, and the sliding cover 3 can be quickly removed. Then, when it is necessary to replace the dust filter 7 above the heat dissipation hole 8, simply pinch the middle part of the dust filter 7 and then pinch the dust filter 7 inward to remove it. When installing, simply bend the dust filter 7 first to make it have a certain curvature, then insert one side of the dust filter 7 into one side of the limiting frame 6, and then insert the other side of the dust filter 7 into the other side of the limiting frame 6 to complete the replacement of the dust filter 7.
[0043] 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.
