Detailed Implementation

[0023] 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.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: an anti-interference enhancement device for automobile antennas, including an anti-interference enhancement device body 100. The anti-interference enhancement device body 100 includes an anti-interference shell 101 for automobile antennas. An antenna main board 102 is fixed to the top of the inner part of the anti-interference shell 101 via a mounting base. A connecting wire 103 is installed at the bottom of the antenna main board 102. An anti-interference outer cylinder 104 is fitted onto the outer surface of the connecting wire 103. A magnetic ring 105 is provided on the inner surface of the anti-interference outer cylinder 104. An elastic sleeve 106 is fixed to the inner surface of the magnetic ring 105, and the inner surface of the elastic sleeve 106 is in tight contact with the outer surface of the connecting wire 103. During installation and use, the magnetic ring 105 can be fitted onto the outer surface of the connecting wire 103 through the elastic sleeve 106. During use, the magnetic ring 105 eliminates interference signals transmitted through the connecting wire 103, facilitating effective anti-interference enhancement of the received signal by the automobile antenna. The specific principle is the prior art. The anti-interference enhancement device body 100 is also provided with:

[0025] The reinforcement installation mechanism includes a fixed connection component disposed at the end of the elastic sleeve 106, an elastic connection component at the inner surface edge of the fixed connection component, and a clamping reinforcement component disposed at the end of the elastic connection component. After the elastic sleeve 106 is clamped and installed on the magnetic ring 105, the reinforcement installation mechanism strengthens and fixes the magnetic ring 105. Even when subjected to force for a long time after installation, the reinforcement installation is still strengthened and fixed, and it is not easy for the elastic force to weaken and loosen.

[0026] In order to facilitate the installation of the internal friction clamping plate 1063 by means of a fixed connection assembly and to facilitate reinforcement after installation, in this embodiment, preferably, the fixed connection assembly includes a fixing groove 1061 formed at both ends of the elastic sleeve 106. A fixing ring 1062 is fixed inside the fixing groove 1061 by adhesive, and the fixing ring 1062 matches the internal structure of the fixing groove 1061. The fixing groove 1061 facilitates the closure and fixed installation of the fixing ring 1062, which is convenient for installation and use.

[0027] To facilitate the elastic connection of the internal friction pressing plate 1063 via the elastic connecting assembly and to enable elastic pressing, in this embodiment, preferably, the elastic connecting assembly includes a limiting groove 1066 formed at the inner edge of the fixing ring 1062. A limiting connecting plate 1065 is provided inside the limiting groove 1066. An elastic block 1067 is provided at the connection between the inner surface of the limiting connecting plate 1065 and the inner surface of the limiting groove 1066. The deformation of the elastic block 1067 causes the limiting connecting plate 1065 to be elastically connected to the inside of the limiting groove 1066, thereby causing the internal friction pressing plate 1063 to be elastically connected through the limiting connecting plate 1065.

[0028] In order to facilitate the reinforcement and fixing of the elastic sleeve 106 during elastic compression, in this embodiment, preferably, the reinforcement and fixing component includes a connecting groove 1064 located on the inner surface of the fixing ring 1062 at the end of the limiting groove 1066. An internal friction pressing plate 1063 is provided inside the connecting groove 1064 at the end of the limiting connecting plate 1065. The inner surface of the internal friction pressing plate 1063 is in tight contact with the outer surface of the connecting wire 103. When the limiting connecting plate 1065 drives the internal friction pressing plate 1063 to elastically connect, the internal friction pressing plate 1063 is elastically pressed against the outer surface of the connecting wire 103 to strengthen the fixed installation.

[0029] The connection mechanism includes a rotating connection component disposed at the connection between the outer surface of the magnetic ring 105 and the inner surface of the anti-interference outer cylinder 104. An elastic reinforcing component is provided at the end edge of the magnetic ring 105. During installation and use, the magnetic ring 105 can be conveniently installed on the inner surface of the anti-interference outer cylinder 104 through the connection mechanism, and can be conveniently disassembled when damaged during use, making the installation and disassembly of the magnetic ring 105 convenient.

[0030] To facilitate quick installation and disassembly of the magnetic ring 105 via the rotating connection assembly, in this embodiment, preferably, the rotating connection assembly includes an external thread structure 1052 formed on the outer surface of the magnetic ring 105, an internal thread structure 1053 formed on the inner surface of the anti-interference outer cylinder 104, and a limiting ring 1054 formed at the inner bottom edge of the anti-interference outer cylinder 104. The external thread structure 1052 and the inner surface of the anti-interference outer cylinder 104 are rotatably connected through the external thread structure 1052 and the internal thread structure 1053. The magnetic ring 105 is rotatably installed on the inner surface of the anti-interference outer cylinder 104 through the external thread structure 1052 and the internal thread structure 1053 until the bottom end of the magnetic ring 105 contacts the surface of the limiting ring 1054 and stops rotating, thus fixing it in place. The front surface of the magnetic ring 105 has four actuating grooves 1051, which facilitate the use of tools to adjust the rotation of the magnetic ring 105 by engaging the actuating grooves 1051.

[0031] To facilitate the rotation and reinforcement installation of the magnetic ring 105 and the anti-interference outer cylinder 104 using the elastic reinforcement component, in this embodiment, preferably, the elastic reinforcement component includes four internally threaded holes 1057 formed at one end of the outer surface of the magnetic ring 105. The internal threads of the internally threaded holes 1057 have threaded posts 1056 rotating inside them. The ends of the threaded posts 1056 are provided with elastic protrusions 1055. The elastic protrusions 1055 can be installed by rotating the threaded posts 1056 and the internal threads of the internally threaded holes 1057. After the magnetic ring 105 rotates, the elastic protrusions 1055 deform and press tightly against the inner surface of the anti-interference outer cylinder 104 for reinforcement installation.

[0032] The working principle and usage process of this utility model are as follows: Before use, this type of car antenna anti-interference enhancement device is installed. First, the elastic protrusion 1055 is fixed to the outer surface of the end of the magnetic ring 105 by rotating the threaded post 1056 inside the threaded hole 1057. Then, the tool is engaged inside the actuating groove 1051 and the magnetic ring 105 is rotated into the anti-interference outer cylinder 104 by the threaded connection between the external thread structure 1052 and the inner surface of the internal thread structure 1053. This is continued until the surface of the elastic protrusion 1055 contacts the end surface of the anti-interference outer cylinder 104, where it is pressed and pushed into the interior, thus allowing the magnetic ring to... The bottom end of 105 contacts the surface of the limiting ring 1054. At this time, the end is deformed by the elastic protrusion 1055 and elastically pressed against the inner surface of the anti-interference outer cylinder 104 for reinforcement and installation, thereby quickly fixing the magnetic ring 105 to the anti-interference outer cylinder 104. It is then pressed onto the surface of the connecting wire 103 by the elastic sleeve 106, which facilitates quick installation and use. Conversely, if the magnetic ring 105 is damaged after long-term use, it can be disassembled and repaired in the opposite way. Compared with the existing disassembly and assembly operations, it is more convenient and improves the convenience of disassembling and assembling the magnetic ring 105 when the anti-interference enhancement device body 100 is installed on the car antenna for anti-interference use.

[0033] Then, when the anti-interference enhancement device body 100 is installed before use, the fixing ring 1062 is closed inside the fixing groove 1061 and fixed with adhesive. When the magnetic ring 105 is tightly installed on the outer surface of the connecting wire 103 through the elastic sleeve 106, the elastic block 1067 deforms and drives the limiting connecting plate 1065 to elastically press against the inner friction pressing plate 1063 until the inner friction pressing plate 1063 is elastically pressed against the outer surface of the connecting wire 103. This facilitates the anti-slip pressing installation through the inner friction pressing plate 1063, which strengthens the tight pressing and fixing between the elastic sleeve 106 and the connecting wire 103. Even when subjected to force for a long time after installation, the installation is still strengthened and fixed, and it is not easy for the elastic force to weaken and loosen. This effectively fixes the anti-interference enhancement device and improves the strengthening and fixing of the anti-interference enhancement device body 100 when it is installed inside the car antenna.
