Description

Technical Field

[0001] The utility model relates to the technical field of indoor antennas, and in particular to an indoor antenna with a protective function. Background Art

[0002] Indoor distributed antennas (indoor distributed antennas) play a vital role in modern wireless communication systems and are mainly used for signal coverage and distribution in indoor environments. Their main function is to enhance and expand the coverage of wireless signals and ensure stable communication signal transmission in complex environments such as large buildings, underground spaces, shopping malls, hotels and office buildings. With the continuous development of mobile communication technology and the increasing demand of users for high-speed and stable communications, indoor distributed antennas are widely used in various places to solve the problems of weak signal coverage and blind spots and improve users' communication experience.

[0003] Existing indoor distributed antennas transmit RF signals from base stations or signal sources to indoor areas through coaxial cables or optical fibers, and then transmit them to various indoor areas through antenna units. Its design usually includes multiple distributed antenna nodes, which can be evenly distributed in the building to ensure comprehensive signal coverage. The indoor distributed antenna system can significantly improve indoor signal strength and quality, reduce signal attenuation and interference, thereby improving communication reliability and user experience. In addition, the indoor distributed antenna also has flexible installation and expansion capabilities, which can be adjusted and optimized according to actual needs to adapt to building environments of different sizes and structures.

[0004] However, most of the existing indoor antennas are installed by screws. Although this installation method can provide a relatively stable fixing effect, in actual use, antennas fixed with screws are relatively troublesome when they need to be disassembled and repaired. Tools are required to remove the screws one by one, which not only increases the complexity and time cost of maintenance work, but may also cause the screws to be lost or damaged.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3, the utility model provides an embodiment: a room-divided antenna with a protective function, comprising a base 1, an antenna body 2 is slidably connected inside the base 1, a fixing ring 3 is fixedly connected to the outer wall of the antenna body 2, a card plate 4 is slidably connected inside the fixing ring 3, a spring 5 is arranged inside the fixing ring 3, one end of the spring 5 is fixedly connected to the inside of the fixing ring 3, the other end of the spring 5 is fixedly connected to the outer wall of the card plate 4, a sliding rod 6 is fixedly connected to the outer wall of the card plate 4, the outer wall of the sliding rod 6 is slidably connected to a limiting ring 7, a limiting groove 8 is arranged inside the limiting ring 7, the outer wall of the sliding rod 6 is slidably connected to the inside of the limiting groove 8, a push rod 9 is fixedly connected to the outer wall of the limiting ring 7, the outer wall of the push rod 9 is slidably connected to the inside of the base 1, an installation component is arranged inside the base 1, and the installation component is used to install and fix the base 1; the installation component comprises a mounting bolt 10, and the outer wall of the mounting bolt 10 is threadedly connected to the inside of the base 1;

[0025] Specifically, when the indoor antenna needs to be disassembled, the limit ring 7 is driven to start rotating by rotating the push rod 9, which allows the slide bar 6 to slide along the limit groove 8. The movement of the slide bar 6 further drives the card plate 4, and compresses the spring 5 while sliding inside the fixed ring 3. The compression process of the spring 5 ensures that the card plate 4 can slide out of the base 1 smoothly, so that the antenna body 2 can slide out of the base 1 easily, thereby quickly and effectively disassembling the indoor antenna and ensuring the stability and reliability of each component during the disassembly process. The push rod 9 and the limit ring 7 can accurately control the progress of the disassembly process, and the function of the spring 5 ensures that after the disassembly is completed, the card plate 4 can automatically reset for the next use or maintenance.

[0026] Reference Figure 2-Figure 4 The outer wall of the base 1 is rotatably connected with a protective cover 11, and the outer wall of the protective cover 11 is fixedly connected with a fixed plate 12; the outer wall of the fixed plate 12 is fixedly connected with a plug plate 18, and the outer wall of the plug plate 18 is slidably connected to the inside of the antenna body 2; the outer wall of the antenna body 2 is fixedly connected with a limit rod 13, and one end of the limit rod 13 is fixedly connected to the limit plate 14; the outer wall of the limit rod 13 is slidably connected with a pull plate 15, and the outer wall of the pull plate 15 is fixedly connected with an insert rod 16; the outer wall of the insert rod 16 is slidably connected to the inside of the antenna body 2, and the outer wall of the insert rod 16 penetrates into the inside of the plug plate 18; the outer wall of the insert rod 16 is sleeved with a spring 2 17, one end of the spring 2 17 is fixedly connected to the outer wall of the antenna body 2, and the other end of the spring 2 17 is fixedly connected to the outer wall of the pull plate 15;

[0027] Specifically, when the indoor antenna needs to be protected, the protective cover 11 is first buckled on the surface of the antenna body 2. The function of the protective cover 11 is to provide external protection and keep the antenna body 2 from being affected by the external environment. Then, the plug plate 18 is slid into the interior of the antenna body 2, and then the pull plate 15 is pulled to stretch the spring 2 17. At the same time, the plug rod 16 slides out from the interior of the antenna body 2. When the plug plate 18 completely slides into the interior of the antenna body 2, the pull plate 15 is released. At this time, the elastic force of the spring 2 17 will push the plug rod 16 back until the plug rod 16 completely slides into the interior of the plug plate 18. This not only improves the practicality of the indoor antenna in harsh environments, but also significantly extends its service life and reduces damage or corrosion caused by the external environment.

[0028] Working principle: When the antenna needs to be disassembled, the limit ring 7 is driven to rotate by rotating the push rod 9, so that the sliding rod 6 can slide along the inside of the limit groove 8, and then the card plate 4 is driven, so that the card plate 4 slides inside the fixing ring 3 while compressing the spring 1 5 until the card plate 4 completely slides out of the base 1, and then the antenna body 2 is slid out of the base 1, so as to achieve the effect of quickly disassembling the indoor antenna, and improve the convenience of the indoor antenna. When the antenna needs to be protected, the protective cover 11 is buckled on the surface of the antenna body 2, and the plug plate 18 is slid into the inside of the antenna body 2, and then the pull plate 15 is pulled to stretch the spring 17 and slide the plug rod 16 out. When the plug plate 18 completely slides into the antenna body 2, the pull plate 15 is released, and the plug rod 16 is pushed back by the elastic force of the spring 17 until the plug rod 16 is inserted into the plug plate 18, so as to achieve the effect of isolating and protecting the indoor antenna, improve the practicality of the indoor antenna, and extend the service life of the indoor antenna.
