[0002] A retractable LNB antenna is an antenna device with adjustable length for receiving or transmitting high-frequency signals.

[0003] LNB antennas operate based on Ampere's law and Faraday's law of electromagnetic induction. When current passes through the antenna, a magnetic field is generated. Changes in the magnetic field generate an electric field, which propagates along the antenna and generates electromagnetic waves, enabling signal transmission or reception.

[0004] Existing LNBs and antennas are connected via plug-in connectors, which typically rely on the physical contact between the plug and socket to achieve electrical connection. However, unreasonable tolerances between the plug and socket allow rainwater and moisture to easily seep in through gaps. Therefore, a retractable LNB antenna is proposed to solve the above problems.

[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 a retractable LNB antenna, including an LNB body 1. A mounting base 2 is fixedly connected to the upper side of the LNB body 1. The mounting base 2 has an annular groove for mounting a sealing gasket 10. An antenna base 5 is snapped onto the upper inner wall of the mounting base 2, providing support for the installation of the antenna body 6. A sliding groove 14 is formed on the right inner wall of the antenna base 5. As the antenna base 5 moves downward, a guide block 13 enters the sliding groove 14. The rotation of the antenna base 5 drives a baffle 12 to rotate via the guide block 13. The baffle 12 is slidably connected to the inner wall of the mounting base 2, rotating synchronously with the rotation of the antenna base 5. When a fixing block 11 enters the mounting base 2 through the antenna base 5, the antenna base 5 rotates 90 degrees. The fixing block 11 is fixed by a plug rod 7, while the baffle 12 rotates synchronously with the rotation of the antenna base 5, sealing the antenna body 6. The opening of the mounting slot 15 is closed. The baffle 12 is fan-shaped, and the upper area of ​​the baffle 12 is larger than the opening area of ​​the mounting slot 15. A guide block 13 is fixedly connected to the left outer wall of the baffle 12. The guide block 13 enters the slide groove 14. The rotation of the antenna base 5 can drive the baffle 12 to rotate through the guide block 13. The outer wall of the guide block 13 slides on the inner wall of the slide groove 14. The guide block 13 is trapezoidal. A sealing gasket 10 is installed on the upper inner wall of the mounting base 2. The rotation of the pressure ring 4 causes the waterproof shell 3 to move downward, so that the lower outer wall of the waterproof shell 3 squeezes the sealing gasket 10 to achieve a sealing effect. The sealing gasket 10 is annular and fixed to the inner side of the mounting base 2. An antenna body 6 is rotatably connected to the antenna base 5. The antenna body 6 is three-section and telescopic. A quick-release assembly is provided on the outer wall of the antenna base 5. The quick-release assembly is used for the installation of the antenna base 5.

[0036] Reference Figure 1 and Figure 4 A waterproof shell 3 slides on the outer wall of the mounting base 2. The upper outer wall of the waterproof shell 3 is inclined, and the lower outer wall of the waterproof shell 3 contacts the upper outer wall of the sealing gasket 10. A pressure ring 4 is threaded onto the antenna base 5. The rotation of the pressure ring 4 causes the waterproof shell 3 to move downward.

[0037] Reference Figures 1-3The quick-installation assembly includes a fixing block 11 with a limiting hole. The upper area of ​​the fixing block 11 is less than or equal to the opening area of ​​the mounting groove 15. The insertion rod 7 is snapped into the fixing block 11 to install the antenna mount 5. The rear outer wall of the fixing block 11 is fixedly connected to the front outer wall of the antenna mount 5. A slip ring 9 is elastically connected to the inner wall of the mounting base 2 via a spring 8. When an external force is applied, the insertion rod 7 moves upward, causing the slip ring 9 to move upward and compress the spring 8. When the external force is removed, the insertion rod 7 and the slip ring 9 are connected. The spring 8 moves downwards under its elastic force, and the outer wall of the slip ring 9 is slidably connected to the inner wall of the mounting base 2. One end of the spring 8 is fixedly connected to the inner wall of the mounting base 2, and the other end of the spring 8 is fixedly connected to the upper outer wall of the slip ring 9. A plug rod 7 is fixedly connected to the inner wall of the slip ring 9. The plug rod 7 is snapped into the fixing block 11 to fix the position of the antenna base 5. The outer wall of the plug rod 7 is slidably connected to the inner wall of the mounting base 2, and the lower outer wall of the plug rod 7 is snapped into the upper inner wall of the fixing block 11. The upper side of the mounting base 2 is provided with a mounting groove 15.

[0038] Working principle: The baffle 12 is slid to a position perpendicular to the mounting groove 15 by the guide block 13. Then, the fixing block 11 on the antenna base 5 enters the mounting base 2 along the mounting groove 15. At this time, the guide block 13 enters the sliding groove 14 as the antenna base 5 moves. Then, the mounting base 2 is rotated 90 degrees and is engaged with the upper inner wall of the fixing block 11 by the insertion rod 7. The position of the mounting base 2 is fixed by fixing the fixing block 11. The baffle 12 is closed by the rotation of the antenna base 5 through the guide block 13. Then, the pressure ring 4 is rotated, which causes the waterproof shell 3 to move down until the sealing gasket 10 is squeezed, thus achieving the waterproof effect.

[0039] 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.
