Description

Technical Field

[0001] The utility model relates to the field of communications, in particular to an adjustable antenna structure. Background Art

[0002] The current antennas on the market have the problem of non-adjustable angles or inconvenient adjustment, which limits the user's ability to obtain the best signal in different communication environments. In response to this shortcoming, users are in urgent need of an antenna structure that can be easily adjusted to improve the flexibility, adaptability and performance of the antenna. In actual use, users may face signal sources or interference sources in different directions, so it is crucial to be able to adjust the angle of the antenna. However, the fixed angle or inconvenient adjustment design in traditional antenna structures limits users from making flexible and convenient adjustments to the antenna. This inconvenience may lead to a decrease in signal quality and affect the communication effect. Especially in complex communication environments, users need an antenna structure that is easy to adjust to meet different needs. Therefore, a new structure that can easily and conveniently adjust the antenna angle is crucial to improving user experience and communication system performance. Utility Model Content

The main body is equipped with a traction buckle, which is used to connect a spiral transmission device to achieve the precise adjustment function of the antenna angle, so that the user can flexibly adjust the direction of the antenna according to needs; the support shaft is also provided with a spiral transmission device, and the spiral rotation device includes an internal threaded tube and an external threaded rod, the internal threaded tube is connected through the support shaft, the external threaded rod is spirally connected to the internal threaded tube, and the other end of the external threaded rod is connected to the traction buckle on the column.

The flexibility of adjustment is enhanced; the end of the bracket shaft is connected to the steering shaft by a hinge, and the setting of the steering shaft allows the antenna to rotate in the vertical direction, which not only improves the directional selection of the antenna, but also increases the overall flexibility of the structure; the steering shaft and the rotating shaft are connected by a coupling, and the setting of the coupling realizes the relative movement between the steering shaft and the rotating shaft, so that the antenna can be rotated and adjusted in the horizontal direction, further improving the multi-directional adjustment capability of the structure; the coupling is firmly connected to the structural base, providing a solid foundation support for the entire antenna structure. The function of the coupling is not only to provide a mechanical connection, but also to ensure the smooth transmission of rotational motion between the rotating shaft and the steering shaft through its stability.

[0012] As a further improvement of the utility model: it also includes a guide rail system, the guide rail system includes a guide rail and a slider, the structural base is arranged on the slider, and the slider is provided with a sliding bearing for sliding on the guide rail. The arrangement of the structural base on the slider makes the entire antenna structure more flexible, and the user can achieve a wider range of adjustments on the guide rail by sliding the structural base.

[0013] As a further improvement of the present invention: the guide rail system further comprises a braking device, which comprises a braking block and a spring device. When the slider slides to an ideal position, the braking device can ensure that the slider stays at this position.

[0026] The present invention is further described with reference to the accompanying drawings and embodiments:

[0027] Detailed description of the utility model:

[0028] See also Figure 1-6 The utility model is an adjustable antenna structure. The object positions on both sides of the bracket axis 1 are provided with connecting buckles for installing the antenna body 2. After the bottom of the antenna body 2 is inserted into the connecting buckle, the bolts are inserted into the holes on the side of the connecting buckle, and then the nuts are used to install it in the holes on the other side of the connecting buckle. It should be noted that the fixing of the bolts and nuts does not need to lock the bottom of the antenna body 2, and some margin should be left so that the antenna body 2 can make a circular motion on one side of the bracket axis 1 with the bottom of the body 2 as the center. The body 2 is provided with a vibrator piece 3, and the vibrator piece 3 is arranged alternately on both sides of the body 2.

[0029] Specific reference Figure 2 In a specific application example, the number of the vibrator pieces 3 is 16, which are arranged alternately on the left and right sides of the main body 2; from the top to the bottom of the main body 2, the length of the vibrator pieces 3 gradually increases, and the spacing distance between the vibrator pieces 3 also gradually increases.

[0030] A traction buckle 4 is provided on one side of the middle end of the main body 2, and the traction buckle 4 is connected to the non-threaded end of the externally threaded rod 5. The non-threaded end of the externally threaded rod 5 is provided with a traction head 51. The traction head 51 and the non-threaded end can rotate relative to each other along the axial direction of the externally threaded rod 5. The threaded end of the externally threaded rod 5 is rotatably connected to the internally threaded tube 6 through threads, and the internally threaded tube 6 is fixed to the bracket shaft 1 by bolts.

[0031] In a specific application example, the number of the antenna and the number of the threaded transmission devices are both two, the two antennas are respectively arranged on both sides of the bracket shaft 1, and the two threaded transmission devices are also arranged on both sides of the corresponding bracket shaft 1.

[0032] The end of the support shaft 1 is provided with a hole for installing one end of the hinge device 8. The other end of the hinge device 8 is installed at one end of the steering shaft 7. The hinge device 8 is connected between the support shaft 1 and the steering shaft 7 by bolts. The other end of the steering shaft 7 is connected to the first connecting shaft 91 of the coupling 9. The second connecting shaft 92 of the coupling 9 is connected to the rotating shaft 10. A damping device 93 is also provided between the first connecting shaft 91 and the second connecting shaft 92. Specifically, a spring device is provided between the first connecting shaft 91 and the second connecting shaft 92 to provide a certain elasticity and damping effect. The rotating shaft 10 is fixedly installed on the structural base 11. The bottom of the structural base 11 is provided with a slider 12 system. Specifically, the slider 12 is fitted with the guide rail 13. The design and shape of the slider 12 are adapted to the guide rail 13 to ensure smooth sliding and minimum friction resistance. The slider 12 can move freely on the guide rail 13 along the guide rail 13, providing flexibility for the adjustment of the structural base 11.

[0033] The working principle of this utility model:

[0034] When the utility model is in use, there are several adjustment modes as follows:

[0035] Antenna concentration adjustment, see Figure 4 When it is determined that the direction of the signal source is relatively concentrated, the external threaded rod 5 can be loosened to make the external threaded rod 5 extend outward from the internal threaded tube 6. Under the traction of the traction buckle 4, the antenna will rotate toward the top of the bracket axis 1 and gradually reach the minimum angle. Finally, the bracket axis 1 forms an angle of 15°. When the two antennas are adjusted to the same angle, a structure with an angle of 30° can be formed, so that the antenna can maximize the signal receiving power in the direction of the extension line of the top of the bracket axis 1. For details, please refer to Figure 5 When the direction of the signal source is more dispersed, the external threaded rod 5 can be tightened to make the external threaded rod 5 enter the internal threaded rod more. Under the action of the traction buckle 4, the antenna will gradually move in the direction perpendicular to the bracket axis 1. When the antenna body 2 is perpendicular to the bracket axis 1, the angle reaches the maximum value. When the two antennas are adjusted to the same angle, a 180° antenna combination can be formed, so that the antenna can maximize the reception rate of the dispersed signals.

[0036] Vertical adjustment, see Figure 6 A hinge device 8 is provided between the bracket shaft 1 and the steering shaft 7, so that the bracket shaft 1 can be adjusted in the vertical direction, further enhancing the adaptability of the antenna to signal reception.

[0037] Horizontal defense line adjustment, a coupling 9 is set between the steering shaft 7 and the rotating shaft 10, so that the steering shaft 7 can be rotated along the central axis on the horizontal defense line to adjust the angle, further enhancing the antenna's adaptability to signal reception.

[0038] For details on position adjustment, see Figure 6 The structural base 11 is arranged on a slider 12, and the slider 12 can slide on a guide rail 13, so that the antenna can find the best position for signal reception, further enhancing the adaptability of the antenna to signal reception.

[0039] The main functions of this utility model:

[0040] By introducing innovative designs such as the bracket shaft 1, steering shaft 7, rotating shaft 10, coupling 9, and guide rail 13 system, the utility model realizes the adjustment of the antenna structure in multiple dimensions, greatly simplifies the operation process, expands the adjustment range, and strengthens key connecting components. Compared with the existing technology, these structural improvements give the antenna greater flexibility and adaptability, allowing users to adjust the angle and orientation more easily. This series of innovations not only improves the performance of the communication system, but also significantly enhances the overall user experience, bringing positive impacts to the advancement and practical application of antenna technology.

[0041] In summary, after reading the utility model document, ordinary technicians in this field can make various other corresponding transformation schemes based on the technical scheme and technical concept of the utility model without creative mental labor, which all fall within the scope of protection of the utility model.
