Description

Technical Field

[0001] The utility model belongs to the technical field of telescopic antennas, and in particular relates to a retractable antenna structure. Background Art

[0002] An antenna is a converter that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium, or vice versa. A retractable antenna is a type of antenna that can be freely retracted. It is widely used in the field of radio communications and provides efficient signal transmission for radio communications.

[0003] The shrinkable sky-type cables currently on the market have the following problems when used:

[0004] 1. When using a traditional retractable antenna, it needs to be pulled out according to the required length of the antenna. When the antenna is fully pulled out, the top of the antenna is prone to shaking due to its long length and thin front end. In windy weather, it will further affect its normal use, making the received signal unstable.

[0005] 2. When the traditional retractable antenna is not in use and needs to be retracted, the retracted antenna is generally exposed to the outside, and dust in the air is easy to adhere to the surface of the antenna, affecting the subsequent use of the antenna. It requires staff to clean it specially, and its dust-proof effect is poor. Utility Model Content

[0006] The utility model aims to provide a retractable antenna structure to solve the technical problems raised in the background technology.

[0029] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a retractable antenna structure of the utility model in conjunction with the accompanying drawings.

[0030] like Figure 1-6 As shown, a retractable antenna structure of the utility model includes an antenna body 1 and a receiving head 4, a first mounting ring 17 is sleeved on the side of the antenna body 1, a second mounting ring 18 is sleeved on the side of the antenna body 1, the first mounting ring 17 and the second mounting ring 18 are fixedly connected to the side of the side plate 3, the top of the side plate 3 is fixedly connected to the support rod 2, the side of the support rod 2 is fixedly connected to the connecting rod 20, and the side of the connecting rod 20 is fixedly connected to the clamping ring 19, by installing the first mounting ring 17 and the second mounting ring 18 on the side of the antenna body 1, and adding the side plate 3 on the side of the first mounting ring 17 and the second mounting ring 18, adding the support rod 2 on the top of the side plate 3, installing the connecting rod 20 on the side of the support rod 2, and adding the clamping ring 19 on the side of the connecting rod 20, when the antenna is fully pulled out, it is only necessary to install the first mounting ring 17 and the second mounting ring 18 on the bottom of the antenna body 1, at this time, the side plate 3 is erected on both sides of the antenna body 1, and the clamping ring 19 on the side of the connecting rod 20 can be clamped around the antenna body 1, effectively preventing the top of the antenna body 1 from shaking, making it more stable.

[0031] The outside of the antenna body 1 is sleeved with a protective frame 5, the top of the protective frame 5 is fixedly connected to a fixing ring 8, an adhesive ring 9 is provided on the side of the fixing ring 8, a sealing gasket 10 is provided at the bottom of the protective frame 5, and a snap ring 7 is sleeved on the outside of the antenna body 1, and the sealing gasket 10 is embedded in the outside of the snap ring 7. By installing the protective frame 5 on the outside of the antenna body 1, a fixing ring 8 is added to the top of the protective frame 5, an adhesive ring 9 is added to the side of the fixing ring 8, and a sealing gasket 10 is installed on the bottom of the adhesive ring 9, and a snap ring 7 is installed on the outside of the antenna body 1. When the retractable antenna is not needed and needs to be retracted, the top of the antenna is directly retracted together with the protective frame 5, and the sealing gasket 10 at the bottom of the protective frame 5 can be embedded in the snap ring 7. At this time, the interface of the sealing gasket 10 prevents dust, water and other substances from entering the inside of the antenna, so that its dustproof effect is better.

[0032] The first mounting ring 17 is fixedly connected to the first mounting plate 14 on the side, and the second mounting ring 18 is fixedly connected to the second mounting plate 16 on the side. By installing the first mounting plate 14 on the side of the first mounting ring 17 and the second mounting plate 16 on the side of the second mounting ring 18, the first mounting ring 17 and the second mounting ring 18 can be installed together using the first mounting plate 14 and the second mounting plate 16.

[0033] The surface of the first mounting plate 14 is fixedly connected to the plug rod 13, one end of the plug rod 13 is fixedly connected to the ball head 12, and the plug rod 13 is inserted into the second mounting plate 16. The plug rod 13 is installed on the surface of the first mounting plate 14, and the ball head 12 is added to one end of the plug rod 13. When the first mounting plate 14 and the second mounting plate 16 need to be fixed, it is only necessary to directly insert the plug rod 13 and the ball head 12 into the second mounting plate 16, and the first mounting plate 14 and the second mounting plate 16 can be fixed at this time.

[0034] A metal ring 11 is embedded in the side of the sealing gasket 10, and a magnetic ring 6 is embedded in the side of the clamping ring 7.

[0036] The working principle of the retractable antenna structure: when using the retractable antenna, it is only necessary to pull the receiving head 4 as needed to pull out the antenna section by section and adjust it to the required length. When the antenna is fully pulled out, it is only necessary to install the first mounting ring 17 and the second mounting ring 18 at the bottom of the antenna body 1, and directly insert the plug rod 13 and the ball head 12 into the second mounting plate 16. At this time, the first mounting plate 14 and the second mounting plate 16 can be fixed. At this time, the side plates 3 are erected on both sides of the antenna body 1, and the clamping rings 19 on the sides of the connecting rod 20 can be clamped around the antenna body 1, effectively preventing the top of the antenna body 1 from shaking. When the antenna needs to be retracted after use, it is only necessary to pull the plug rod 13 directly out of the first mounting plate 14, and retract the top of the antenna together with the protective frame 5. The sealing gasket 10 at the bottom of the protective frame 5 can be embedded in the clamping ring 7, and the metal ring 11 is adsorbed by the magnetic ring 6 to fix the protective frame 5 to prevent the protective frame 5 from loosening. At this time, the interface of the sealing gasket 10 prevents dust, water and other substances from entering the interior of the antenna, so that its dustproof effect is better.
