Abstract
Description
Technical Field
[0001] This utility model relates to the field of tuner heads, and more particularly to a corrosion-resistant television tuner head. Background Technology
[0002] In a television signal receiving system, the low-noise block downconverter (LNB) plays a crucial role. It is responsible for receiving and processing high-frequency signals and is one of the key components that ensures normal television playback.
[0003] Existing technologies have the following drawbacks: Traditional TV tuner designs often involve complex disassembly and maintenance of the base and mounting housing, requiring specialized tools or cumbersome procedures. This causes significant inconvenience to daily inspection and maintenance, increasing maintenance costs and time. Secondly, in outdoor TV signal reception scenarios, such as outdoor relay stations in remote areas, receiving devices near the sea or industrial pollution areas, corrosive gases in the air (such as sulfur dioxide, hydrogen chloride, etc.), water vapor from high humidity environments, and various dust impurities can easily penetrate the tuner's interior. Prolonged exposure to such environments can lead to corrosion of the internal electronic components and metal structures, resulting in decreased signal reception quality, frequent equipment malfunctions, and severely impacting the normal transmission and reception of TV signals. Therefore, a corrosion-resistant TV tuner is proposed to address these issues. Utility Model Content

[0009] As a further description of the above technical solution:
[0010] The sleeve is made of flexible rubber material.
[0011] As a further description of the above technical solution:
[0012] The sleeve is fitted onto the outer wall of the connector.
[0013] As a further description of the above technical solution:
[0014] Both the adsorption sheet and the ring sheet are hollow circular in shape.
[0015] As a further description of the above technical solution:
[0016] The left sidewall of the L-block is fixedly connected to one end of the reset spring, and the other end of the reset spring is fixedly connected to the left inner wall of the mounting shell.

[0034] 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.
[0035] Reference Figures 1-3This utility model provides an embodiment of an anti-corrosion television tuner, comprising a base shell 1, a mounting shell 2 detachably mounted on the top of the base shell 1, a fixing block 3 fixedly connected to the outer wall of the base shell 1, the fixing block 3 mainly connecting to block L 5, a limiting mechanism provided on the inner wall of the mounting shell 2, a slot provided on the outer wall of the mounting shell 2 to allow block L 5 to move laterally along the slot, a guide tube 6 fixedly connected to the inner wall of the mounting shell 2 to allow block L 5 to move laterally without deviation of the movement trajectory, and a limiting groove 7 provided on the inner wall of the fixing block 3 for limiting. The right side of the slot 7 is open, allowing block L 5 to be moved out of the opening. A ring plate 8 is fixedly connected to the bottom of the mounting shell 2. An airbag 9 is fixedly connected to the outer wall of the ring plate 8. During use, the airbag 9 will deform and compress the internal air. An insertion hole 11 is provided at the top of the bottom shell 1. The shape of the insertion hole 11 is the same as that of the ring plate 8, allowing the ring plate 8 to be inserted into the insertion hole 11. A connector 12 is fixedly connected to the right side wall of the mounting shell 2. The connector 12 mainly connects to external connectors and can receive signal source devices such as antennas. A protective component is provided on the right side wall of the bottom shell 1.
[0036] The limiting mechanism includes L-block 5, which is slidably connected to the inner wall of the mounting shell 2. The upper part of L-block 5 is protruding, and L-block 5 can be moved by hand by moving the protruding part. The left side wall of L-block 5 is elastically connected to the mounting shell 2 through a return spring 4.
[0037] Reference Figures 1-3 The protective component includes an elastic rope 13, which is fixedly connected to the right side wall of the bottom shell 1. The elastic rope 13 is made of elastic material and can be stretched and deformed. A sleeve 14 is fixedly connected to the end of the elastic rope 13. The sleeve 14 is hollow and can be fitted onto the connector 12. A ring plate 15 is fixedly connected to the outer wall of the sleeve 14. The ring plate 15 is made of metal and can be used to limit the movement by adhering to the adsorption plate 10. The adsorption plate 10 is attached to the left end of the ring plate 15. The sleeve 14 is made of flexible rubber material and can deform. When not compressed, it will return to its original position. Figure 1 In this state, the insert 14 is fitted onto the outer wall of the connector 12, and both the adsorption plate 10 and the ring plate 15 are hollow circles.
[0038] Reference Figures 2-4The left side wall of L-block 5 is fixedly connected to one end of the return spring 4. When L-block 5 moves to the right, it will stretch the return spring 4. When resetting, the elastic force of the return spring 4 will bring L-block 5 back to its original position. The other end of the return spring 4 is fixedly connected to the left inner wall of the mounting shell 2. L-block 5 is snapped into the inner wall of the limiting groove 7. L-block 5 is slidably connected to the outer wall of the guide tube 6. The ring plate 8 is inserted into the inner wall of the insertion hole 11. The airbag 9 is attached to the inner wall of the insertion hole 11. The surfaces of the bottom shell 1 and the mounting shell 2 are coated with fluorocarbon paint. Fluorocarbon paint has super corrosion resistance and has extremely high tolerance to various strong acids, strong alkalis and organic solvents. It can maintain good protective performance in complex and harsh corrosive environments.
[0039] Working principle: When the bottom shell 1 and mounting shell 2 need to be disassembled for maintenance, L-block 5 can be moved to the right and the return spring 4 can be stretched, allowing L-block 5 to move to the right end opening of the limit groove 7. The lower part of L-block 5 can then be moved out of the opening. At this time, L-block 5 can be released, and the reverse elastic force of the return spring 4 will cause L-block 5 to return to its original position. As L-block 5 moves out, the ring plate 8 and airbag 9 disengage from the slot of the insertion hole 11. Since the airbag 9 is not compressed, it returns to its original position. Figure 4 When installing the base shell 1 and mounting shell 2, the top of the base shell 1 will compress the airbag 9, causing it to deform. The elasticity of the airbag 9 will allow it to fit tightly into the slot of the socket 11, sealing the entire base shell 1 and mounting shell 2. This prevents corrosive gases and moisture from entering the high-frequency head. Combined with the fluorocarbon coating on the surfaces of the base shell 1 and mounting shell 2, this ensures the long-term usability of the base shell 1 and mounting shell 2. The installation process can be carried out by following the steps described above.
[0040] When connector 12 is not in use, the sleeve 14 can be fitted onto connector 12, allowing the adsorption plate 10 and the ring plate 15 to adhere to each other and position the entire sleeve 14, which can prevent moisture and dust from affecting connector 12. When in use, the sleeve 14 can be removed from the outer wall of connector 12.
[0041] 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.
