Description

Technical Field

[0001] The present invention relates to the field of antenna technology, and in particular to a dual-broadband dual-polarization omnidirectional ceiling antenna. Background Art

[0002] Indoor ceiling antenna is a kind of mobile communication system antenna, which is mainly used for indoor signal coverage and plays an important role in indoor signal distribution and transmission. Outdoor signal coverage uses plate antennas with high power, strong signal and long coverage. Relatively speaking, indoor coverage, such as conference venues, hotels, office buildings, cinemas, residential buildings, etc., requires indoor distributed systems to cover, so small ceiling antennas are used. They are beautiful in appearance, do not affect the indoor appearance, have low power, and can cover one floor. Usually, in the lower floors of buildings, such as underground parking lots, the signal is weak and the mobile phone cannot be used normally, forming a blind spot and shadow area of ​​mobile communication, which will have a huge impact on people's mobile traffic. The wide application of ceiling antennas has effectively solved this problem and greatly improved human life.

[0003] The antenna in the prior art utilizes the elastic deformation of the plastic clip to quickly install and fix the antenna on the ceiling. However, in actual use, in order to support and fix the antenna, the plastic clip has a large supporting force to fix the ceiling hole. When the antenna is damaged and needs to be repaired and disassembled, the antenna body is blocked and the antenna can only be pulled out by brute force by manpower. This makes the plastic clip very easy to be damaged, affecting the service life of the clip and causing damage to the ceiling.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figures 1 to 6 , the present invention provides a technical solution:

[0028] A dual-wideband dual-polarization omnidirectional ceiling antenna comprises an antenna body 1. A connecting line 2 is arranged on the upper outer surface of the antenna body 1 near the left side, and the connecting line 2 is electrically connected to the internal parts of the antenna body 1. A fixing frame 3 is symmetrically fixedly connected to the front and rear sides of the upper outer surface of the antenna body 1 near the center. A steering mechanism 4 is arranged between two groups of the fixing frames 3. A fixing mechanism 6 is fixedly connected above the steering mechanism 4. The fixing mechanism 6 and the steering mechanism 4 work in cooperation with each other, can have a better fixing and clamping effect on the ceiling antenna, are easy to install and disassemble, can automatically adjust the direction of the ceiling antenna as needed, and have strong overall practicality.

[0029] By adopting the above technical solution, when it is necessary to install the antenna, first reserve a circular hole of suitable diameter at the specified position of the ceiling, and pass the fixing mechanism 6 through the circular hole to clamp the ceiling, so that the antenna body 1 can be effectively clamped and fixed. It has a simple structure and is easy to operate. It is easy to disassemble and install, will not damage the ceiling, and has a long service life. At the same time, the user can adjust the inclination angle and direction of the antenna by the steering mechanism 4 to adjust the signal transmission range of the antenna according to different spatial distributions, which brings a good user experience and greatly improves the use range of the antenna. Finally, the connecting line 2 is connected to the signal transmission line, and the power is turned on. The antenna can work normally. The overall structure is simple and practical.

[0030] As an embodiment of the present invention, Figure 2 and Figure 3 As shown, the fixing mechanism 6 includes a fixing cylinder 61, a center block 1 62, a through slot 2 63, a connecting rod 1 64, a center block 2 65, a connecting rod 2 66, a fixing rod 67, a fixing plate 68, and a spring 69. A fixing cylinder 61 is arranged above the steering mechanism 4. The upper end outer surface of the fixing cylinder 61 is fixedly connected with the center block 1 62. The upper end outer surface of the center block 1 62 is penetrated with a through slot 2 63. The annular outer surface of the center block 1 62 is equidistantly hinged with a plurality of groups of connecting rods 1 64. A center block 2 65 is arranged above the center block 1 62. The annular outer surface of the center block 2 65 corresponds to the connecting rod 1 64. A plurality of groups of connecting rods 66 are equidistantly provided on the circumference of the position, and the corresponding connecting rods 1 64 and 2 66 are hinged to each other. A fixing rod 67 is fixedly connected to the outer surface of the lower end of the center block 2 65. The fixing rod 67 passes through the through slot 2 63 and the fixed cylinder 61, and its bottom end is fixedly connected to the steering mechanism 4. A fixing plate 68 is fixedly connected to the position of the annular outer surface of the fixing rod 67 near the bottom end of the fixed cylinder 61. The fixing plate 68 and the fixed cylinder 61 match each other and are movably connected. A spring 69 is sleeved on the outer surface of the fixing rod 67, and the spring 69 is located between the top of the inner surface of the fixed cylinder 61 and the fixing plate 68.

[0031] By adopting the above technical solution, when in use, the user first fixes the position of the fixing tube 61 and pushes the fixing rod 67 upward, which can drive the fixing plate 68 fixedly connected thereto to move upward to squeeze the spring 69. At the same time, the fixing rod 67 moving upward can drive the center block 2 65 fixedly connected thereto to move upward and separate from the center block 1 62. As the distance between the two becomes farther and farther, and the connecting rod 1 64 and the connecting rod 2 66 respectively hinged to the two are hinged to each other, the connecting rod 1 64 and the connecting rod 2 66 will gradually be driven to stretch vertically, thereby reducing the diameter of the fixing mechanism 6, and then the fixing mechanism 6 will be By passing through the round hole reserved on the ceiling and loosening the fixing rod 67, the fixing rod 67 can be driven to return to its original position under the action of the spring 69, and the connecting rod 1 64 and the connecting rod 2 66 are then close to restore the horizontal position, so that they can be just stuck on the ceiling. Through the cooperation of other components arranged on the fixing tube 61, the ceiling can be clamped, and then the position of the antenna can be fixed. When disassembly is required, only the fixing rod 67 needs to be pushed upwards, and the fixing mechanism 6 can be pulled out of the round hole, so that it can be easily disassembled. The overall structure is simple, which greatly facilitates the user's use, and will not cause damage to the ceiling during the disassembly and installation process.

[0032] As an embodiment of the present invention, Figure 2 As shown, the number of the connecting rods 1 64 and 2 66 is four, and they form a group of two. The ends of each group of connecting rods 1 64 and 2 66 away from the center block 1 62 are hinged to each other.

[0033] By adopting the above technical solution, by setting up multiple groups of connecting rods 1 64 and connecting rods 2 66, the ceiling can be clamped more effectively, so that the position of the antenna can be fixed more stably, and the connecting rods 1 64 and connecting rods 2 66 are hinged to each other, ensuring that when the two ends of the two are close to the center block 1 62 and move away from each other, the two can be stretched in the vertical direction, thereby shortening the horizontal diameter of the fixing mechanism 6, so that the fixing mechanism 6 can more conveniently pass through the circular hole reserved on the ceiling, and when the two return to their original state, they can be just engaged on the ceiling and will not fall off.

[0034] As an embodiment of the present invention, Figure 3 As shown, the annular outer surface of the fixing tube 61 is provided with threads, and a clamping block 7 is threadedly connected to the outer surface thereof. The clamping block 7 is designed as a circular structure, and its radius is equal to the length of the connecting rod 64.

[0035] By adopting the above technical solution, when the fixing mechanism 6 passes through the circular hole reserved on the ceiling and returns to its original position, the connecting rod 64 will rotate downward under the action of the spring 69 and approach the clamping block 7, so that the ceiling can be clamped, thereby fixing the position of the antenna. The user can control the distance between the clamping block 7 and the connecting rod 64 according to the thickness of the ceiling by rotating the clamping block 7, so that the antenna can be clamped and fixed on ceilings of different thicknesses, and the overall practicality is high.

[0036] As an embodiment of the present invention, Figure 3 and Figure 4 As shown, a card slot 8 is provided on the right side of the inner surface of the fixed cylinder 61 near the bottom end, a through slot three 9 is provided on the right side outer surface of the fixed rod 67 near the bottom end, a card block 10 is slidably connected inside the through slot three 9, a spring piece two 11 is provided on the left side outer surface of the card block 10, and the spring piece two 11 and the through slot three 9 are matched and engaged with each other, a guide groove 12 is provided on the right side outer surface of the fixed rod 67 near the bottom of the through slot three 9, the guide groove 12 is a right-angle structure design, and it is interconnected with the through slot three 9, a pressure rod 13 is provided inside the guide groove 12, and the pressure rod 13 is fixedly connected to the card block 10.

[0037] By adopting the above technical solution, when the fixing rod 67 moves upward, it will drive the card block 10 to move upward. When it corresponds to the card slot 8, under the action of the second spring piece 11, the card block 10 is resisted from entering the card slot 8 and engaging with each other, thereby fixing the position of the fixing rod 67, effectively preventing the spring 69 from resisting the fixing rod 67 from moving downward, making it convenient for the user to insert the fixing mechanism 6 into the round hole. When the center block 1 62 enters the round hole, the user can press the pressure rod 13 to drive the card block 10 fixedly connected thereto to move to the left and squeeze the second spring piece 11, whereupon the card block 10 and the card slot 8 are separated from each other, stopping the fixation of the fixing rod 67. Under the action of the spring 69, the fixing mechanism 6 can be driven to clamp and fix the antenna. When the card block 10 is separated from the fixing tube 61, it is always in a protruding state outward under the action of the elastic force of the second spring piece 11.

[0038] As an embodiment of the present invention, Figure 4 As shown, the through slot three 9 and the clamping block 10 are designed as T-shaped structures and are slidably connected, the spring piece two 11 is designed as a C-shaped structure, and is made of elastic metal material, and the clamping slot 8 is designed as a right-angled triangle structure and matches the clamping block 10.

[0039] By adopting the above technical scheme, the through slot three 9 and the card block 10 are designed as T-shaped structures to match each other so that the contact between the two is closer, and it is ensured that under the action of the elastic force of the spring piece two 11, the card block 10 will not be ejected from the outside of the through slot three 9. When the card block 10 moves upward to contact the fixed cylinder 61, since its right outer surface is designed as an inclined structure, under the resistance of the inner wall of the fixed cylinder 61, the card block 10 will enter the inside of the through slot three 9 and squeeze the spring piece two 11. Since the spring piece two 11 is designed as a C-shaped structure, its two ends will extend to the upper and lower ends along the through slot three 9, so that the spring piece two 11 has good stretchability, ensuring its normal operation. When the card block 10 contacts the card slot 8, the spring piece two 11 can push the card block 10 into the inside of the card slot 8 to engage the fixed rod 67.

[0040] As an embodiment of the present invention, Figure 5 and Figure 6 As shown, the steering mechanism 4 includes a fixed box 41, a motor 42, a fixed block 43, a movable groove 44, a bearing 45, a rotating shaft 46, and a locking assembly 5. The lower end of the fixed rod 67 is fixedly connected to the fixed box 41, and the motor 42 is arranged inside the fixed box 41. The output shaft of the motor 42 extends out of the outer surface of the bottom end of the fixed box 41, and the top end thereof is fixedly connected to the fixed block 43. The front end of the fixed block 43 is an outer surface through which a movable groove 44 is opened, and the inner surface of the movable groove 44 is fixedly connected to the bearing 45, and the inner surface of the bearing 45 is fixedly connected to the rotating shaft 46. The front and rear ends of the rotating shaft 46 are evenly fixedly connected to the fixing frame 3, and the locking assembly 5 is arranged inside the fixed block 43.

[0041] By adopting the above technical solution, when it is necessary to adjust the angle of the antenna body 1 according to the spatial layout, it is only necessary to open the locking assembly 5 and rotate the antenna body 1 to rotate it around the rotating shaft 46. When it is rotated to a suitable angle, the locking assembly 5 is locked, and the antenna body 1 cannot rotate in the vertical direction. The motor 42 is controlled to rotate, and the fixed block 43 can be driven to rotate through the output shaft. Since the fixed block 43 is rotatably connected to the rotating shaft 46 through the bearing 45, the two ends of the rotating shaft 46 are fixedly connected to the fixing frame 3, and the fixing frame 3 is fixedly connected to the outer surface of the upper end of the antenna body 1, the antenna body 1 will be driven to rotate, and the antenna body 1 can be adjusted to a suitable angle, which greatly improves the use experience of the antenna and has strong practicality.

[0042] As an embodiment of the present invention, Figure 5As shown, the locking assembly 5 includes a gear 51, a slide groove 52, a slider 53, a spring piece 54, a through groove 55, and a lever 56. The gear 51 is fixedly connected to the middle position of the outer surface of the rotating shaft 46. The slide groove 52 is provided at the bottom end of the inner surface of the movable groove 44 corresponding to the position of the gear 51. The slider 53 is slidably connected inside the slide groove 52. The outer surface of the upper end of the slider 53 is provided with teeth, and the slider is meshed with the gear 51. The outer surface of the lower end of the slider 53 is provided with a spring piece 54, and the spring piece 54 and the slide groove 52 are matched and engaged with each other. The right outer surface of the fixed block 43 is provided with a through groove 55 corresponding to the position of the slider 53. The through groove 55 is communicated with the slide groove 52. A lever 56 is provided inside the through groove 55, and the left end of the lever 56 is fixedly connected to the slider 53.

[0043] By adopting the above technical solution, in the natural state, under the action of the elastic force of the spring sheet 54, the slider 53 is prevented from moving upward, so that the teeth on the outer surface of the upper end thereof mesh with the upper end gear 51, thereby fixing the position of the rotating shaft 46, so that the position of the antenna body 1 cannot be changed. When it is necessary to adjust the inclination angle of the antenna body 1, it is only necessary to move the lever 56 downward to drive the slider 53 fixedly connected thereto to move downward, squeeze the spring sheet 54, and the teeth on the upper end of the slider 53 are disengaged from the gear 51. The user can then rotate the antenna body 1 to drive the rotating shaft 46 to rotate. When it is rotated to a suitable position, the lever 56 is released. Under the action of the elastic force of the spring sheet 54, the slider 53 is driven to move upward and mesh with the gear 51, fixing the position of the rotating shaft 46 and preventing the antenna body 1 from rotating. The inclination angle of the antenna body 1 can be easily adjusted, thereby greatly improving the scope of use of the device and having strong overall practicality.

[0044] Working principle: when it is necessary to install the antenna, first reserve a circular hole of suitable diameter at the designated position of the ceiling. The user can control the distance between the clamp block 7 and the connecting rod 1 64 by rotating the clamp block 7 according to the thickness of the ceiling, so that the clamp block 7 can be fixed to the ceiling of different thicknesses. The position of the fixing tube 61 is fixed, and the fixing rod 67 is pushed upward, which can drive the fixing plate 68 fixedly connected thereto to move upward to squeeze the spring 69. At the same time, the fixing rod 67 moving upward can drive the center block 2 65 fixedly connected thereto to move upward and separate from the center block 1 62. As the distance between the two becomes farther and farther, and the connecting rods 1 64 and 2 66 respectively hinged to the two are hinged to each other, the connecting rods 1 64 and 2 66 will gradually be driven to pull vertically. When the fixing rod 67 moves upward, the card block 10 is driven to move upward. When the card block 10 corresponds to the card slot 8, the card block 10 is resisted from entering the card slot 8 and engaging with each other under the action of the second spring piece 11, so as to fix the position of the fixing rod 67 and effectively prevent the spring 69 from resisting the fixing rod 67 from moving downward. Then, the fixing mechanism 6 is passed through the round hole reserved in the ceiling. The user can press the pressure rod 13 to drive the card block 10 fixedly connected thereto to move to the left and squeeze the second spring piece 11. Then, the card block 10 and the card slot 8 are separated from each other, and the fixing of the fixing rod 67 is stopped. Under the action of the spring 69, the fixing rod 67 can be driven to return to its original position, and the connecting rod 1 64 and the connecting rod 2 66 are close to each other. When the antenna body 1 is nearly restored to a horizontal position, the connecting rod 1 64 will rotate downward and approach the clamping block 7, so that the ceiling can be clamped, thereby fixing the position of the antenna. When it is necessary to disassemble, it is only necessary to push the fixing rod 67 upward, and the fixing mechanism 6 can be pulled out of the round hole, so that it can be easily disassembled. The overall structure is simple, which greatly facilitates the use of the user, and the ceiling will not be damaged during the disassembly and installation process. When it is necessary to adjust the angle of the antenna body 1 according to the spatial layout, it is only necessary to move the lever 56 downward to drive the slider 53 fixedly connected thereto to move downward, squeeze the spring piece 1 54, and the teeth on the upper end of the slider 53 will be disengaged from the gear 51. The user can rotate the antenna body 1 to drive the rotating shaft 46 to rotate, and when it is rotated to a suitable position, release the lever 56. , under the action of the elastic force of the spring sheet 54, the slider 53 is driven to move upward and engage with the gear 51, fixing the position of the rotating shaft 46 to prevent the antenna body 1 from rotating, so that the inclination angle of the antenna body 1 can be easily adjusted, and the motor 42 is controlled to rotate, and the fixed block 43 can be driven to rotate through the output shaft. Since the fixed block 43 is rotatably connected with the rotating shaft 46 through the bearing 45, the two ends of the rotating shaft 46 are fixedly connected to the fixing frame 3, and the fixing frame 3 is fixedly connected to the outer surface of the upper end of the antenna body 1, the antenna body 1 will be driven to rotate, and then the antenna body 1 can be adjusted to a suitable angle, which greatly improves the use range of the antenna. Finally, the connecting line 2 is connected to the signal transmission line, and the power is turned on. The antenna can work normally. The overall structure is simple and practical.
