Abstract
Description
Technical Field
[0001] This utility model relates to a dual-frequency antenna, specifically a dual-frequency antenna, and belongs to the field of dual-frequency antenna technology. Background Technology
[0002] In the field of wireless communication, dual-band antennas are widely used in Wi-Fi, 5G, IoT and other devices to achieve simultaneous support for the 2.4GHz and 5GHz frequency bands.
[0003] However, when using dual-band antennas on IoT devices, the antennas are typically connected to the devices via cables. Since these cables are fixed to the antennas, excess cables are often exposed and tangled outside the device. This can easily lead to tangling and knotting due to movement or stacking, requiring extra time to organize before each use and reducing operational efficiency. Furthermore, the lack of a dedicated storage structure when not in use means that randomly coiled cables may deform due to compression or bend at the connectors, affecting signal transmission stability. Exposed metal connectors are also susceptible to moisture and dust corrosion, leading to poor contact or impedance changes and increasing the risk of signal attenuation. Exposed connectors may also deform or even break during handling or collisions, causing antenna malfunction. Utility Model Content
[0004] The purpose of this invention is to provide a dual-band antenna to solve the above problems, prevent the connecting wires of the dual-band antenna body from being exposed to the outside and oxidizing when not in use, which could easily lead to malfunctions of the connecting wires of the dual-band antenna body and affect its use, and also prevent the connecting wires from getting tangled and knotted, affecting subsequent use.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a dual-frequency antenna, comprising a dual-frequency antenna body, a winding structure installed at the bottom end of the dual-frequency antenna body, the winding structure including a top plate, the top plate being fixedly connected to the bottom end of the dual-frequency antenna body, a fixing column being fixedly connected to the bottom end of the top plate, a base plate being fixedly connected to the bottom end of the fixing column, a sliding groove being provided on the side end of the top plate, a sliding rod being slidably connected in the sliding groove, a protective cover being fixedly connected to the outer end of the sliding rod, multiple stop bars being fixedly connected in a circular array at the bottom end of the top plate, a fixing seat being fixedly connected to the top end of the base plate, a rotating rod being rotatably connected inside the fixing seat, a fixing groove being provided at the front end of the protective cover, a sliding plate being slidably connected inside the protective cover, and a spring being fixedly connected between the protective cover and the sliding plate.
[0006] Preferably, the slide groove and the slide rod are both convex in shape.
[0007] Preferably, a limiting block is fixedly connected to the bottom end of the slide rod, and the limiting block abuts against the top plate.
[0008] Preferably, a magnetic suction plate is fixedly connected to the bottom end of the base plate, and the magnetic suction plate is electrically connected to the internal power supply.
[0009] Preferably, a limiting structure is installed on the dual-frequency antenna body. The limiting structure includes a limiting ring. The limiting ring is rotatably connected to the side end of the dual-frequency antenna body. An abutment block is fixedly connected to the outer end of the limiting ring. The abutment block abuts against the slide rod.
[0010] Preferably, a positioning ring is fixedly connected to the bottom side of the dual-frequency antenna body, and the positioning ring and the limiting ring are rotatably connected.
[0011] Preferably, the side end cross-section of the limiting ring is generally concave, and the side end cross-section of the positioning ring is generally convex.
[0012] Preferably, the limiting ring has multiple slots arranged in a ring array inside, and a locking block is slidably connected inside the bottom end of the dual-frequency antenna body.

[0014] Preferably, a reset structure is installed on the fixed base and the rotating rod. The reset structure includes a fixed shaft, and fixed shafts are fixedly connected to both sides of the rotating rod. A torsion spring is fixedly connected between the fixed shaft and the fixed base.
[0015] The beneficial effects of this utility model are as follows: When using the dual-frequency antenna body, the connecting wires of the dual-frequency antenna body can be wound and placed by the fixing post. At the same time, the connecting wires are protected by the top plate, bottom plate and protective cover to prevent the connecting wires from being exposed to the outside and oxidizing when the dual-frequency antenna body is not in use, which could easily lead to failure of the connecting wires and affect use. It can also prevent the connecting wires from getting tangled when storing the dual-frequency antenna body, which would affect subsequent use. The connecting wires wound on the fixing post can be positioned by the stop bar and the rotating rod. After the connecting wires are pulled out, the fixing groove can lock and protect the connecting wires, preventing the connecting wires from getting tangled when using the dual-frequency antenna body.

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.
[0023] Please see Figures 1-5 As shown, a dual-band antenna includes a dual-band antenna body 1. A winding structure 2 is installed at the bottom of the dual-band antenna body 1. The winding structure 2 includes a top plate 201. The top plate 201 is fixedly connected to the bottom of the dual-band antenna body 1. A fixing post 202 is fixedly connected to the bottom of the top plate 201. A base plate 203 is fixedly connected to the bottom of the fixing post 202. A sliding groove 204 is provided on the side of the top plate 201. A sliding rod 205 is slidably connected in the sliding groove 204. A protective cover 206 is fixedly connected to the outer end of the sliding rod 205. Multiple baffles 207 are fixedly connected in a ring array at the bottom of the top plate 201. A fixing seat 208 is fixedly connected to the top of the base plate 203. A rotating rod 209 is rotatably connected inside the fixing seat 208. A fixing groove 210 is provided at the front end of the protective cover 206. A sliding plate 211 is slidably connected inside the protective cover 206. A spring 212 is fixedly connected between the protective cover 206 and the sliding plate 211.
[0024] As a technical optimization of this utility model, the slide groove 204 is generally convex in shape, and the slide rod 205 is generally convex in shape, which facilitates the sliding of the slide rod 205 and the slide groove 204.
[0025] As a technical optimization of this utility model, the bottom end of the slide rod 205 is fixedly connected to a limiting block 213, and the limiting block 213 abuts against the top plate 201, thereby limiting the slide rod 205.
[0026] As a technical optimization of this utility model, a magnetic suction plate 214 is fixedly connected to the bottom end of the base plate 203. The magnetic suction plate 214 is electrically connected to the internal power supply, thereby enabling the positioning of the dual-frequency antenna body 1.
[0027] As a technical optimization of this utility model, a limiting structure 3 is installed on the dual-frequency antenna body 1. The limiting structure 3 includes a limiting ring 301. The limiting ring 301 is rotatably connected to the side end of the dual-frequency antenna body 1. An abutting block 302 is fixedly connected to the outer end of the limiting ring 301. The abutting block 302 abuts against the sliding rod 205, thereby fixing the sliding rod 205.
[0028] As a technical optimization of this utility model, a positioning ring 303 is fixedly connected to the bottom side of the dual-frequency antenna body 1. The positioning ring 303 and the limiting ring 301 are rotatably connected. The side cross-section of the limiting ring 301 is concave in shape, and the side cross-section of the positioning ring 303 is convex in shape, so as to limit the positioning ring 301.
[0029] As a technical optimization of this utility model, the limiting ring 301 has multiple slots 304 arranged in a ring array inside, and a locking block 305 is slidably connected inside the bottom end of the dual-frequency antenna body 1. The locking block 305 and the slots 304 engage, and a spring piece 306 is fixedly connected between the dual-frequency antenna body 1 and the locking block 305. The slots 304 have an arc-shaped structure, and the side end of the locking block 305 has an arc-shaped structure, so as to engage and fix the limiting ring 301.
[0030] As a technical optimization of this utility model, a reset structure 4 is installed on the fixed base 208 and the rotating rod 209. The reset structure 4 includes a fixed shaft 401. The fixed shaft 401 is fixedly connected to both sides of the rotating rod 209. A torsion spring 402 is fixedly connected between the fixed shaft 401 and the fixed base 208, so as to drive the rotating rod 209 to rotate and reset.
[0031] In use, when using the dual-frequency antenna body 1, the positioning ring 303 rotates the limiting ring 301. After the contact block 302 and the sliding rod 205 separate, the protective cover 206 slides upward. The sliding rod 205 and the sliding groove 204 limit the protective cover 206. After the protective cover 206 slides to the top, the limiting block 213 and the top plate 201 abut against it, limiting the protective cover 206. Then, the connecting wire of the dual-frequency antenna body 1 is taken out by rotating outward. When the connecting wire abuts against the rotating rod 209 on the fixing seat 208, the connecting wire can drive the rotating rod 209 to rotate outward. After pulling out a sufficiently long connecting wire, the torsion spring 402 can drive the fixing shaft 401 to rotate and reset. Therefore, the rotating rod 209 can reset again to limit the connecting wire. Then, the protective cover 206 slides downward. When the sliding plate 211 abuts against the connecting wire, the fixing groove 210 can fix the connecting wire. The dual-band antenna body 1 is protected by a locking mechanism to prevent excess wires from becoming tangled and affecting its use. The magnetic plate 214 allows the dual-band antenna body 1 to be placed on the external casing. When not in use, the protective cover 206 is slid down to rotate the connecting wires in the opposite direction and place them within the multiple retainers 207. A spring 212 drives the sliding plate 211 to slide back to its original position, sealing the fixing groove 210. This prevents the connecting wires from being exposed when not in use, thus avoiding tangling and oxidation of the connectors, which could affect the use of the dual-band antenna body 1. Then, the limiting ring 301 is rotated. When the contact block 302 and the sliding rod 205 abut, the protective cover 206 is limited. The elasticity of the spring piece 306 causes the locking block 305 to slide and engage with the locking groove 304, thus limiting and fixing the limiting ring 301. Therefore, the connecting wires can be stored and placed away again.
