Technical Field
[0001] This utility model relates to an antenna, and more particularly to a foldable indoor antenna. Background Technology
[0002] An antenna is a transducer that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or vice versa. It is a component in wireless equipment used to transmit or receive electromagnetic waves. Engineering systems that utilize electromagnetic waves to transmit information, such as radio communication, broadcasting, television, radar, navigation, electronic warfare, remote sensing, and radio astronomy, all rely on antennas to function.
[0003] In the prior art, patent application number CN202320182016.3 discloses a foldable and easy-to-store indoor antenna, including a suction cup. The upper part of the suction cup is provided with a tube body. The tube body is provided with a first telescopic tube, and the first telescopic tube is provided with a second telescopic tube. The outer surfaces of the tube body, the first telescopic tube, and the second telescopic tube are provided with positioning rings. The positioning rings are all provided with mounting grooves. An antenna rod is movably connected to the mounting grooves, so that the antenna rod can be stored in the positioning rings and the first and second telescopic tubes can be retracted into the tube body.
[0004] However, in the above-mentioned technology, since the antenna mast is exposed outside the tube body, it is easily bumped and damaged when stored and carried, and it is also easy to snag on other objects. In addition, in order to achieve complete retraction of the antenna mast, the antenna masts on the first telescopic tube and the second telescopic tube need to be repositioned, which results in the antenna masts on the first telescopic tube and the second telescopic tube not being on the same plane. Therefore, when the antenna masts on the first telescopic tube and the second telescopic tube are fully extended, the space occupied is relatively large. Utility Model Content
[0005] The main purpose of this invention is to propose a foldable indoor antenna, which aims to solve the technical problems of existing antennas being easily damaged and taking up a large amount of space.
[0006] To achieve the above objectives, this utility model proposes a foldable indoor antenna, comprising a first column and a second column. The top of the first column is provided with a sliding groove, and the second column is slidably connected to the first column and embedded in the sliding groove. The top of the second column is provided with a mounting groove, in which a first antenna rod is embedded. The first antenna rod is slidably connected to the second column. The upper ends of opposite sides of the first column are each provided with a vertically downward first groove, in which a second antenna rod is embedded. One end of the second antenna rod is rotatably connected to the upper end of the first column. The second column and the first column are provided with second grooves on the same sides as the first column where the first grooves are located. A third antenna rod is embedded in the second groove, in which one end of the third antenna rod is rotatably connected to the upper end of the second column. A fixing suction cup is provided on the side of the first column that avoids the first groove.
[0007] Preferably, the first column has a third groove at the end opposite to the fixed suction cup, and a support plate is embedded in the third groove. The first column has rotating columns on opposite sides at the upper end of the third groove, and rotating grooves are provided on both sides of one end of the support plate. The rotating columns are embedded in the rotating grooves so that the support plate is rotatably connected to the first column.
[0008] Preferably, the second column is fixedly provided with a damping rubber ring at the upper end of the slide groove, and the damping rubber ring abuts against the first antenna rod.
[0009] Preferably, the first groove is provided with a rotating shaft, and one end of the second antenna rod is provided with a rotating groove, and the second antenna rod is embedded in the rotating groove.
[0010] Preferably, the upper end of the first column is provided with a screw hole communicating with the first groove on the side that avoids the first groove, and a locking screw for fixing the second antenna mast is provided in the screw hole.

[0023] This invention proposes a foldable indoor antenna.
[0024] like Figure 1 As shown, in one embodiment of this utility model, a foldable indoor antenna includes a first column 1 and a second column 2. The top of the first column 1 is provided with a sliding groove, and the second column 2 is embedded in the sliding groove and slidably connected to the first column 1. The top of the second column 2 is provided with a mounting groove, and a first antenna rod 7 is embedded in the mounting groove. The first antenna rod 7 is slidably connected to the second column 2. The upper ends of opposite sides of the first column 1 are provided with vertically downward first grooves 3. A second antenna rod 4 is embedded in the first groove 3. One end of the second antenna rod 4 is rotatably connected to the upper end of the first column 1. The second column 2 and the first column 1 are provided with second grooves 5 on the same sides as the first column 1 where the first grooves 3 are provided. A third antenna rod 6 is embedded in the second groove 5. One end of the third antenna rod 6 is rotatably connected to the upper end of the second column 2. A fixing suction cup 8 is provided on the side of the first column 1 that avoids the first groove 3.
[0025] The first column 1 and the second column 2 are made of high-strength engineering plastics, such as ABS plastic. To ensure good signal reception, the first antenna mast 7, the second antenna mast 4, and the third antenna mast 6 are made of metal, such as aluminum alloy. The fixing suction cup 8 is made of silicone rubber, which has good adsorption and aging resistance, ensuring that the antenna can be stably adsorbed on various smooth surfaces. The first column 1 is manufactured using injection molding. At the top of the first column 1, a groove is precisely formed according to the dimensions of the second column 2. At the upper ends of opposite sides of the first column 1, vertically downward grooves are also formed using injection molding. The first groove 3 is designed according to the dimensions of the second antenna rod 4. Its length should be sufficient to accommodate the second antenna rod 4, its width slightly larger than the diameter of the second antenna rod 4, and its depth moderate to ensure stable installation. On the side of the first column 1 that avoids the first groove 3, a flat area is designed for installing and fixing the suction cup 8. The second column 2 is processed using an injection mold to form an installation groove at its top. The dimensions of the installation groove are adapted to the first antenna rod 7, with a length slightly larger than the first antenna rod 7, and its width and depth matching the external dimensions of the first antenna rod 7. On the same sides of the first groove 3 provided on the second column 2 and the first column 1, a second groove 5 is injection molded. The dimensions of the second groove 5 are similar to those of the first groove 3, with the length, width, and depth determined according to the dimensions of the third antenna mast 6. The second column 2 is carefully inserted into the sliding groove at the top of the first column 1, ensuring that the second column 2 slides smoothly in the sliding groove without any jamming. Then, the first antenna mast 7 is inserted into the mounting groove at the top of the second column 2. The rotating shaft 16 is installed in the pre-drilled hole in the first groove 3, ensuring that the rotating shaft 16 is securely installed and will not loosen. Then, the next day... The end of the pole 4 with the rotating groove 15 is aligned with the rotating shaft 16 for installation, so that the pole 4 can rotate flexibly around the rotating shaft 16 the next day. The tightness of the fit between the rotating shaft 16 and the rotating groove 15 can be adjusted appropriately, such as by adding or removing washers, to achieve the ideal rotation effect. Then, the rotating shaft 14 is installed in the reserved hole of the second groove 5. Then, the rotating seat 13 of the third antenna pole 6 is installed with the rotating shaft 14 to ensure that the third antenna pole 6 can rotate smoothly around the rotating shaft 14. Apply an appropriate amount of strong glue to the designated position of the first column 1 and stick the silicone rubber fixing suction cup 8 to that position.
[0026] In this embodiment, the first antenna rod 7 is completely hidden by embedding it inside the second column 2. Then, the second column 2 is embedded inside the first column 1, and the third antenna rod 6 is housed inside the second column while the second column 2 is retracted and hidden. The second antenna rod 4 is then housed and hidden through the first groove 3 on the first column 1. This achieves the goal of hiding all antenna rods, preventing the antenna from colliding with or hooking onto other objects and causing damage. In addition, the first antenna rod 7, the second antenna rod 4, and the third antenna rod 6 are all set on the same plane, making them flatter and reducing their space occupation. Furthermore, the suction cups on the side walls can attach the antenna device to the wall or other equipment, making installation simple and convenient and occupying little space.
[0027] Preferably, a third groove 9 is provided at the end of the first column 1 away from the fixed suction cup 8, and a support plate 10 is embedded in the third groove 9. Rotating columns are provided on opposite sides of the upper end of the first column 1 at the third groove 9. Rotating grooves are provided on both sides of one end of the support plate 10. The rotating columns are embedded in the rotating grooves so that the support plate 10 is rotatably connected to the first column 1.
[0028] Preferably, the second column 2 is fixedly provided with a damping rubber ring at the upper end of the slide groove. The damping rubber ring abuts against the first antenna rod 7, and the first antenna rod 7 is suspended on the second column 2 by means of the damping rubber ring.
[0029] Preferably, such as Figure 3 As shown, the first groove 3 is provided with a rotating shaft 16, and the second rod 4 is provided with a rotating groove 15 at one end, and the second rod 4 is embedded in the rotating groove 15.
[0030] Preferably, such as Figure 2 As shown, the upper end of the first column 1 is provided with a screw hole that communicates with the first groove 3 on one side. The screw hole is provided with a locking screw 11 for fixing the second telegraph rod 4. The second telegraph rod 4 is fixed by the locking screw 11 so that it can be suspended at any angle.
[0031] Preferably, such as Figure 3 As shown, the second groove 5 is provided with a rotating shaft 14, and one end of the third antenna rod 6 is provided with a rotating seat 13. The third antenna rod 6 is embedded in the rotating seat 13, and the third antenna rod 6 can be unfolded by the cooperation of the rotating shaft 14 and the rotating seat 13.

[0033] Optionally, the top of the first antenna mast 7 is provided with an annular groove, and the top of the second column 2 is provided with a third groove 9 at the sliding groove. The annular groove can be exposed through the third groove 9, making it easier to pull out the first antenna mast 7 by prying the annular groove.
[0034] Specifically, the working principle and usage process of this utility model are as follows: The first antenna rod 7 is completely hidden by embedding it into the second column 2. Then, the second column 2 is embedded into the first column 1, and the third antenna rod 6 is stored in the second column while the second column 2 is retracted and hidden. Then, the second antenna rod 4 is stored and hidden by the first groove 3 on the first column 1, thereby hiding all the antenna rods and preventing the antenna from colliding with or hooking onto other objects and causing damage. In addition, the first antenna rod 7, the second antenna rod 4, and the third antenna rod 6 are all set on the same plane, making them flatter and reducing the space occupation. In addition, the suction cup on the side wall can adsorb the antenna device onto the wall or other equipment, making installation simple and convenient and occupying little space.
[0035] Optionally, a fixed suction cup 8 is also provided at the bottom of the first column 1.
[0036] Optionally, the first column 1 and the second column 2 are provided with clearance grooves at the first groove 3 and the second groove 5, and the sides of the second antenna rod 4 and the third antenna rod 6 are provided with grooves for unfolding them. By inserting a fingernail into the groove through the clearance groove, the second antenna rod 4 and the third antenna rod 6 can be pulled out, which is simple and convenient.
