Description

Technical Field

[0001] This utility model relates to the field of omnidirectional antenna technology, and in particular to a portable omnidirectional antenna. Background Technology

[0002] The working principle of an omnidirectional antenna is based on the radiation characteristics of electromagnetic waves. Through specific shape and structural design, electromagnetic waves are radiated uniformly in the horizontal direction. Its ideal radiation pattern is "donut" shaped, with the antenna located at the center. The signal radiation is strongest in the horizontal plane and gradually weakens in the vertical direction.

[0003] In existing technologies, omnidirectional antennas for certain frequency bands such as ultra-shortwave and microwave often use multiple metal rods as the core radiating element in order to adapt to the frequency band characteristics and ensure radiation efficiency. By arranging the elements evenly along the circumference of a disc-shaped base, a multi-element disc structure is formed.

[0004] Since the signal gain of an omnidirectional antenna is directly related to the electrical length of the vibrator, in order to improve the signal radiation intensity and transmission distance of a specific frequency band, technicians usually extend the physical length of the vibrator to match the corresponding electrical length. This directly leads to an increase in the radial dimension of the omnidirectional antenna after assembly, and a significant increase in the overall space occupied. At the same time, the vibrators of existing omnidirectional antennas are mostly fixed assembly structures, which makes the protruding metal vibrators easy to collide with external objects and cause damage during outdoor operations and transportation.

[0005] Therefore, a portable omnidirectional antenna is proposed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing omnidirectional antennas, where the vibrator is mostly a fixed assembly structure, making the protruding metal vibrator prone to collision with external objects and damage during outdoor operations and transport. Therefore, a portable omnidirectional antenna is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a portable omnidirectional antenna, including a bracket, a frame fixedly mounted on the circumferential surface of the bracket, a plurality of long elements rotatably connected to the circumferential surface of the frame, a chuck fixedly mounted on the upper end of the bracket, a plurality of short elements rotatably connected to the circumferential surface of the chuck, a storage plate fixedly mounted on the circumferential surface of the bracket, and a plurality of first slots and second slots formed on the circumferential surface of the storage plate, wherein the size of the first slots is adapted to the size of the short elements, and the size of the second slots is adapted to the size of the long elements.

[0008] The effect achieved by the above components is as follows: by setting up a storage plate, a first slot and a second slot, when it is necessary to move the omnidirectional antenna, the long vibrator is inserted into the second slot of the storage plate and the short vibrator is inserted into the first slot, so as to realize the orderly storage of the vibrator, greatly reduce the overall radial size of the antenna, reduce the space occupation, and thus facilitate the carrying and transfer of the omnidirectional antenna.

[0009] Preferably, a retaining ring is rotatably fitted on the circumferential surface of the storage plate, and a notch is provided on the circumferential surface of the retaining ring. The dimensions of the long vibrator and the short vibrator are both adapted to the dimensions of the notch on the retaining ring.

[0010] The effect achieved by the above components is as follows: by using the blocking and limiting function of the retaining ring, the short or long oscillator is prevented from coming out during the transfer process, and the notch can easily slide the long or short oscillator into the corresponding second or first slot.

[0011] Preferably, a plurality of protrusions are fixedly fitted on the circumferential surface of the retaining ring.

[0012] The effect achieved by the above components is that the protrusions can increase the friction on the surface of the retaining ring, thereby facilitating the rotation of the retaining ring.

[0013] Preferably, the bracket is rotatably connected to the position of the card frame with a first rotating ring, and the surface of the first rotating ring is fixedly fitted with a plurality of first support plates adapted to the long vibrator.

[0014] The effect achieved by the above components is that the first support plate can provide stable support for the long oscillator, ensuring that the relative position of the long oscillator and the bracket is fixed.

[0015] Preferably, the bracket is rotatably connected to the position of the chuck with a second rotating ring, and the surface of the second rotating ring is fixedly fitted with a plurality of second support plates adapted to the short vibrator.

[0016] The effect achieved by the above components is that the second support plate can provide stable support for the short oscillator, ensuring that the relative position of the short oscillator and the bracket is fixed.

[0017] Preferably, the surface of the first tray is fixedly fitted with two first guide plates, and the surface of the second tray is fixedly fitted with two second guide plates.

[0018] The above components achieve the following effects: the first guide plate can easily slide the long oscillator into the first support plate, and the second guide plate can easily slide the short oscillator into the second guide plate.

[0019] Preferably, a first flexible sleeve is fixedly fitted to the circumferential surface of the long oscillator, and a second flexible sleeve is fixedly fitted to the circumferential surface of the short oscillator.

[0020] The aforementioned components achieve the following effects: the first flexible sleeve on the surface of the long oscillator and the second flexible sleeve on the surface of the short oscillator can reduce collision and friction with the storage plate, and prevent damage to the long and short oscillators due to vibration or contact during the transfer process.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a storage plate, a first slot, and a second slot, when it is necessary to move the omnidirectional antenna, the long vibrator is inserted into the second slot of the storage plate and the short vibrator is inserted into the first slot, so as to achieve orderly storage of the vibrators, greatly reduce the overall radial size of the antenna, reduce space occupation, and thus facilitate the carrying and transfer of the omnidirectional antenna.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] like Figures 1-4As shown, this utility model provides a portable omnidirectional antenna, including a bracket 1. A frame 2 is fixedly mounted on the circumferential surface of the bracket 1. Several long elements 3 are rotatably connected to the circumferential surface of the frame 2. A chuck 4 is fixedly mounted on the upper end of the bracket 1. Several short elements 5 are rotatably connected to the circumferential surface of the chuck 4. A storage plate 6 is fixedly mounted on the circumferential surface of the bracket 1. Several first slots 7 and second slots 8 are formed on the circumferential surface of the storage plate 6. The size of the first slots 7 is adapted to the size of the short elements 5, and the size of the second slots 8 is adapted to the size of the long elements 3. By setting up the storage plate 6, the first slots 7 and the second slots 8, when it is necessary to move the omnidirectional antenna, the long elements 3 are inserted into the second slots 8 of the storage plate 6. The short vibrator 5 is inserted into the first slot 7, achieving orderly storage of the vibrator, significantly reducing the overall radial size of the antenna and reducing space occupation, thus facilitating the carrying and transfer of the omnidirectional antenna. The circumferential surface of the storage plate 6 is fitted with a retaining ring 9, and the circumferential surface of the retaining ring 9 has a notch. The size of the long vibrator 3 and the size of the short vibrator 5 are both adapted to the size of the notch on the retaining ring 9. The retaining ring 9 is used to block and limit the movement, preventing the short vibrator 5 or the long vibrator 3 from coming out during the transfer process. The notch allows the long vibrator 3 or the short vibrator 5 to slide into the corresponding second slot 8 or first slot 7. Several protrusions 10 are fixedly installed on the circumferential surface of the retaining ring 9. The protrusions 10 can increase the friction of the surface of the retaining ring 9, thus facilitating the rotation of the retaining ring 9.

[0027] like Figures 2-4 As shown, the bracket 1 is rotatably connected to the position of the chuck 2 with a first rotating ring 11. Several first support plates 12, adapted to the long vibrator 3, are fixedly mounted on the surface of the first rotating ring 11. The first support plates 12 provide stable support for the long vibrator 3, ensuring the relative position of the long vibrator 3 and the bracket 1 is fixed. The bracket 1 is rotatably connected to the position of the chuck 4 with a second rotating ring 13. Several second support plates 14, adapted to the short vibrator 5, are fixedly mounted on the surface of the second rotating ring 13. The second support plates 14 provide stable support for the short vibrator 5, ensuring the relative position of the short vibrator 5 and the bracket 1 is fixed. The surface of the first support plates 12 is fixedly mounted with... Equipped with two first guide plates 15, and two second guide plates 16 fixedly mounted on the surface of the second support plate 14. The first guide plates 15 facilitate the sliding of the long vibrator 3 into the first support plate 12, and the second guide plates 16 facilitate the sliding of the short vibrator 5 into the second guide plates 16. The circumferential surface of the long vibrator 3 is fixedly mounted with a first flexible sleeve 17, and the circumferential surface of the short vibrator 5 is fixedly mounted with a second flexible sleeve 18. The first flexible sleeve 17 on the surface of the long vibrator 3 and the second flexible sleeve 18 on the surface of the short vibrator 5 can reduce collision and friction with the storage plate 6, and prevent damage to the long vibrator 3 and the short vibrator 5 due to vibration or contact during the transfer process.

[0028] The overall working principle is as follows: uniform radiation in the horizontal azimuth plane is achieved through the coordinated operation of the long vibrator 3 and the short vibrator 5. The long vibrator 3 focuses on improving the signal radiation intensity and transmission distance, while the short vibrator 5 assists in optimizing the uniformity of near-field signal coverage. In use, the long vibrator 3 and the short vibrator 5 are respectively removed from the second slot 8 and the first slot 7 of the storage plate 6 and supported to the horizontal working position. Then, by rotating the first rotating ring 11 and the second rotating ring 13, the first support plate 12 and the second support plate 14 are driven to rotate synchronously. At this time, the first support plate 12 and the second support plate 14 provide stable support for the long vibrator 3 and the short vibrator 5, respectively, ensuring that the relative positions of the long vibrator 3 and the short vibrator 5 with the bracket 1 are fixed, avoiding signal distortion caused by the offset of the radiation unit, and ensuring the uniformity and stability of the horizontal signal radiation intensity. The first guide plate 15 can easily slide the long vibrator 3 into the first support plate 12, and the second guide plate 16 can easily slide the short vibrator 5 into the second guide plate 16.

[0029] When the omnidirectional antenna needs to be moved, the long element 3 and the short element 5 are rotated out from the first support plate 12 and the second support plate 14. Then, the first rotating ring 11 and the second rotating ring 13 are rotated in the opposite direction to release the support plates from limiting the movement of the elements. Subsequently, the long element 3 and the short element 5 are rotated respectively to insert the long element 3 into the second slot 8 of the storage plate 6 and the short element 5 into the first slot 7, achieving orderly storage of the elements, significantly reducing the overall radial size of the antenna and reducing space occupation. During the storage process, the retaining ring 9 is rotated, and after the retaining ring 9 is aligned with the first slot 7 or the second slot 8, Slide the short vibrator 5 or long vibrator 3 into the first slot 7 or the second slot 8. After storage, continue to rotate the retaining ring 9. The retaining ring 9 blocks and limits the movement to prevent the short vibrator 5 or long vibrator 3 from coming out during the transfer. The protrusion 10 increases the friction on the surface of the retaining ring 9, making it easier to rotate the retaining ring 9. At the same time, the first flexible sleeve 17 on the surface of the long vibrator 3 and the second flexible sleeve 18 on the surface of the short vibrator 5 can reduce the collision and friction between them and the storage plate 6, avoiding damage to the long vibrator 3 and the short vibrator 5 due to vibration or contact during the transfer process.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
