Abstract
Description
Technical Field
[0001] This utility model relates to the field of antenna technology, and in particular to a ceiling-mounted antenna. Background Technology
[0002] The indoor antenna is designed with broadband technology and is suitable for signal relay in cellular mobile communication systems. When providing signal coverage in the field, an indoor antenna needs to be placed to avoid indoor blind spots. The indoor antenna can improve the problem of weak indoor signals caused by various factors in the entire radio antenna system, thus enabling the entire radio antenna system to operate effectively.
[0003] When installing an indoor ceiling-mounted antenna, the angle and height need to be adjusted to ensure the antenna functions properly and achieves optimal signal reception. Currently, most indoor ceiling-mounted antennas require drilling mounting holes in the ceiling, inserting the screw from the antenna into the holes, and then tightening the nut to secure it to the ceiling. This screw-and-nut installation method prevents the angle of the ceiling-mounted antenna from being adjusted, affecting signal quality and coverage. During use, the reception strength of a ceiling-mounted antenna varies depending on its location and angle. While a fixed installation on the ceiling ensures stability, it lacks the flexibility to adjust to multiple angles as needed, reducing user experience. Utility Model Content
[0004] To address the aforementioned issues, this invention provides a ceiling-mounted antenna that allows adjustment of the antenna's orientation and angle to achieve optimal signal quality and coverage.
[0005] Therefore, the technical solution of this utility model is: a ceiling-mounted antenna, including an antenna body and a mounting bracket. The antenna body includes a base plate, an antenna feeding system, and an antenna cover. The antenna feeding system is placed inside the antenna cover and the base plate. A connecting post is provided below the base plate, and a through hole for the feed line to pass through is provided inside the connecting post. A protruding adjustment part is provided on the outside of the connecting post. A first spherical surface and a second spherical surface are respectively provided at both ends of the adjustment part, and the centers of the first spherical surface and the second spherical surface are not coaxial. The mounting bracket includes a mounting base and two locking blocks. A first spherical groove matching the first spherical surface is provided on the mounting base, and a second arcuate groove matching the second spherical surface is provided on the opposite side of the locking blocks. The two locking blocks can move towards each other on the mounting base and are locked onto the adjustment part.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme: an adjusting screw is rotatably mounted on the mounting base, with the adjusting screw having opposite thread directions on both sides with the middle as the boundary; the locking block is provided with a through screw hole, through which the adjusting screw passes, and the two are threadedly engaged.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: a guide post is installed on the mounting base, and a through guide hole is provided on the locking block. The guide post passes through the guide hole, and the two are slidably engaged.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the end of the adjusting screw is provided with a locking nut.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: a mounting screw is provided below the mounting base. The mounting screw is hollow inside and connected to the first spherical groove for the feeder to pass through.
[0010] During installation, the two locking blocks are separated. The feed line of the antenna body passes through the first spherical groove into the mounting screw of the mounting base. The first spherical surface of the adjustment part on the antenna body is in contact with the first spherical groove, and the second spherical surface is located in the arc groove of the two locking blocks. At this time, the arc groove and the second spherical surface are in a non-interfering state. At this time, the antenna body can be rotated according to the test data to obtain the optimal azimuth and angle of the antenna body. Then, the adjustment screw is rotated, which can make the two locking blocks move towards each other. The arc groove is locked on the second spherical surface, thereby fixing the antenna body. Since the centers of the first spherical surface and the second spherical surface are not concentric or coaxial, the first spherical groove of the mounting base and the arc groove of the locking block can lock the adjustment part of the antenna body, preventing the antenna body from shifting.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: a spherical adjustment part is provided below the antenna body. The centers of the first spherical surface and the second spherical surface on the adjustment part are not concentric or coaxial, so that the adjustment part can be locked by the mounting base and the locking block and will not rotate relative to each other. The position of the locking block can be adjusted by adjusting the screw. The locking block can be loosened during installation to adjust the azimuth and angle of the antenna and obtain the best signal quality and coverage. Attached Figure Description

Detailed Implementation
[0020] In the description of this utility model, it should be noted that the directional terms such as "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.
[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.
[0022] See the attached drawings. The ceiling-mounted antenna of this embodiment includes an antenna body 1 and a mounting bracket 2. The antenna body 1 includes a base plate 11, an antenna feeding system, and an antenna cover 12. The antenna feeding system is housed within the antenna cover 12 and the base plate 11. A connecting post 13 is located below the base plate 11, and the connecting post 13 has a through hole for the feed line 14 to pass through. The antenna feeding system is a mature existing technology and will not be described in detail here.
[0023] The connecting column 13 has a protruding adjustment part 15 on its outer side. The two ends of the adjustment part 15 are respectively provided with a first spherical surface 16 and a second spherical surface 17. The centers of the first spherical surface 16 and the second spherical surface 17 are not concentric or on the same axis. That is to say, after the first spherical surface 16 and the second spherical surface 17 are tightly fitted with the corresponding spherical groove, they will be locked by the spherical groove and will not rotate relative to each other.
[0024] The mounting bracket 2 includes a mounting base 21 and two locking blocks 22. The mounting base 21 is provided with a first spherical groove 23 that matches the first spherical surface 16. The two locking blocks 22 are provided with a second arcuate groove 24 that matches the second spherical surface 17 on their opposite sides. The two locking blocks 22 can move towards each other on the mounting base 21 and are locked onto the second spherical surface 17 of the adjusting part 15, which can firmly restrict the adjusting part 15 and prevent the adjusting part 15 from rotating.
[0025] An adjusting screw 25 is rotatably mounted on the mounting base 21. The adjusting screw 25 has opposite threads on both sides, with the center as the dividing point. One side of each of the two locking blocks 22 has a through-hole 26 through which the adjusting screw 25 passes, forming a threaded engagement. Rotating the adjusting screw 25 drives the two locking blocks 22 to move relative to each other or in opposite directions, i.e., the two locking blocks 22 close or separate. For smoother movement, a guide post 27 is mounted on the mounting base 21, and a through-hole 28 is provided on each locking block 22. The guide post 27 passes through the guide hole 28, and the two slide together. A locking nut 29 is provided at the end of the adjusting screw 25, with a locking thread of opposite direction at one end. For example, rotating the adjusting screw clockwise closes the locking blocks, while a counter-clockwise locking thread can be selected. When the locking nut locks the adjusting screw, it does not affect the locking effect of the locking blocks, thus securing the adjusting screw more firmly.
[0026] The mounting base 21 is provided with a mounting screw 3. The mounting screw 3 is hollow inside and communicates with the first spherical groove 23 to allow the feeder cable 14 to pass through. The mounting screw 3 can be fixed to the ceiling and locked with a nut, and the feeder cable can be connected to the equipment.
[0027] During installation, the two locking blocks 22 are separated. The feed line 14 of the antenna body 1 passes through the first spherical groove 23 into the mounting screw 3 of the mounting base 21. The first spherical surface 16 of the adjustment part 15 on the antenna body 1 is in contact with the first spherical groove 23, and the second spherical surface 17 is located in the arc groove 24 of the two locking blocks 22. At this time, the arc groove 24 and the second spherical surface 17 are in a non-interfering state. At this time, the antenna body 1 can be rotated according to the test data to obtain the optimal azimuth and angle of the antenna body 1. Then, the adjustment is rotated. The screw 25, when adjusted, allows the two locking blocks 22 to move towards each other. The arc groove 24 locks onto the second spherical surface 17, thereby fixing the antenna body 1. Since the centers of the first spherical surface 16 and the second spherical surface 17 are not concentric or coaxial, the first spherical groove 23 of the mounting base 21 and the arc groove 24 of the locking block 22 can lock the adjustment part 15 of the antenna body 1, preventing the antenna body 1 from shifting and ensuring that the antenna body maintains the best orientation and angle to obtain the best signal quality and coverage.
[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
