Description

Technical Field

[0001] This utility model relates to the field of glue rod antenna technology, specifically an adjustable glue rod antenna. Background Technology

[0002] An antenna is a device that converts electrical signals into electromagnetic waves and transmits them, or receives electromagnetic waves and converts them back into electrical signals. It is a key component in wireless communication systems and is widely used in broadcasting, television, mobile communications, satellite communications, radar, and other fields. Among these, the rubber rod antenna is a common type of external omnidirectional antenna, typically composed of a thin, flexible wire and a plastic shell. This type of antenna is popular due to its small size, lightweight design, and ease of installation.

[0003] Chinese Patent Publication No. CN221201518U discloses a novel WIFI 6E adhesive rod antenna, including a fixing component, an adhesive rod antenna body, a telescopic component mounted on the top of the fixing component, a universal adjustment component mounted on the top of the telescopic component, a telescopic rod movably sleeved on the inner side of the fixing cylindrical frame, a spring fixedly connected to the inner side of the cylindrical groove, a cylindrical block fixedly connected to the other end of the spring, a rectangular block fixedly connected to the other end of the cylindrical block, and a fixing rod fixedly connected to the side of the rectangular block away from the cylindrical block. By providing the telescopic component, pressing the fixing rod causes the rectangular block to... The telescopic rod retracts into the inner side of the second rectangular slot, thus separating the rectangular block from the first rectangular slot. Then, the telescopic rod moves upward along the inner side of the fixed cylindrical frame, allowing it to extend and improve signal reception. Releasing the fixing rod allows the cylindrical block to push the rectangular block into the inner side of the first rectangular slot under the elastic force of the spring, thus fixing the telescopic rod. However, this telescopic adjustment method is relatively cumbersome, involves many components, resulting in higher costs and a larger overall size. It also has high requirements for the installation environment and cannot meet the current demand for compact, lightweight, and easy-to-install antennas. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an adjustable glue rod antenna, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable glue rod antenna, including a connector, a fixed housing is provided on one side of the connector via a rotating shaft, an antenna column is provided inside the fixed housing, a telescopic antenna sleeve is fitted on the surface of the antenna column, and a movable protective shell is provided on the surface of the telescopic antenna sleeve.

[0006] Optionally, a threaded connection port is provided on one side of the connector, and a sealing soft plug is provided inside the threaded connection port.

[0007] Optionally, a scale is provided on the surface of the fixed housing.

[0008] Optionally, a damping ring is provided on the inner wall of the movable protective shell.

[0009] Optionally, a retaining ring is provided on the top of the fixed housing, and an assembly opening is provided on the surface of the retaining ring.

[0010] Optionally, the telescopic antenna sleeve is provided with locking blocks on both sides near the bottom, and the size of the locking blocks is adapted to the size of the assembly port.

[0011] This utility model provides an adjustable rubber rod antenna, which has the following beneficial effects:

[0012] 1. This adjustable rubber rod antenna allows for flexible length adjustment to improve signal gain through the connection between the antenna post and the telescopic antenna sleeve. Alternatively, the antenna direction can be adjusted through the swivel shaft and threaded connection, greatly enhancing the antenna's flexibility. At the same time, the antenna has a simple overall structure, low manufacturing cost, and small size, meeting the requirements for compact and lightweight antennas.

[0013] 2. This adjustable rubber rod antenna uses a sealing soft plug to protect the threaded connection. A scale allows for precise adjustment by the operator. A damping ring increases friction between the movable protective shell and the fixed shell, preventing the antenna from retracting due to gravity or impact when the telescopic antenna sleeve extends. The fixed shell's retaining ring and assembly port, along with the locking blocks on the telescopic antenna sleeve, facilitate assembly and prevent excessive pulling of the antenna sleeve.

[0021] The surface of the telescopic antenna sleeve 4 is provided with a movable protective shell 5. The connection between the movable protective shell 5 and the telescopic antenna sleeve 4 can be reinforced by threads or bolts. The inner wall of the movable protective shell 5 is provided with a damping ring 10. The damping ring 10 increases the friction between the movable protective shell 5 and the fixed shell 2, preventing the antenna from retracting on its own due to gravity or collision when the telescopic antenna sleeve 4 is extended. The top of the fixed shell 2 is provided with a retaining ring 11, and the surface of the retaining ring 11 has an assembly opening 12. The telescopic antenna sleeve 4 is provided with locking blocks 13 on both sides near the bottom. The size of the locking blocks 13 is adapted to the size of the assembly opening 12, so that the telescopic antenna sleeve 4 with the locking blocks 13 is aligned with the assembly opening 12 on the retaining ring 11 of the fixed shell 2 and inserted into the fixed shell 2, which facilitates the assembly of the parts by the installer. Then, when the telescopic antenna sleeve 4 is rotated, the retaining ring 11 blocks the locking blocks 13 when the installer pulls the telescopic antenna sleeve 4, preventing the telescopic antenna sleeve 4 from being completely pulled out.

[0022] In this invention, the working steps of the device are as follows:

[0023] First, assemble the connector 1 and the fixed housing 2 together using the pivot 6. Then, install the antenna column 3 inside the fixed housing 2. Next, align the telescopic antenna sleeve 4 with the locking block 13 and insert it into the fixed housing 2 with the assembly port 12 on the retaining ring 11. Then, rotate the telescopic antenna sleeve 4 and install the movable protective shell 5 on the telescopic antenna sleeve 4 to protect it.

[0024] When in use, remove the sealing plug 8 inside the threaded connection port 7, install the antenna on the device connection end, and then, according to the requirements, use the scale 9 to directly pull the movable protective shell 5 on the surface to precisely adjust the extension length of the telescopic antenna sleeve 4 so that the antenna can adapt to the installation environment and signal requirements.
