Description

Technical Field

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

[0002] A high-frequency array omnidirectional antenna is a type of antenna that combines high-frequency technology with an array antenna structure. It has the characteristic of uniformly radiating electromagnetic waves in a 360° azimuth angle. At the same time, array technology is used to improve the antenna's gain, directivity and other performance indicators. Many high-frequency array omnidirectional antennas adopt vertical polarization, arranging the elements in a vertical direction.

[0003] The above-mentioned and existing technologies have the following drawbacks: When using a high-frequency array omnidirectional antenna, in order to obtain better coverage, the bracket is fixed to the high building wall with expansion bolts, and then the omnidirectional antenna is fixed with clamps and nuts. When the omnidirectional antenna needs to be inspected, tools are used to loosen the clamps and nuts. However, since the omnidirectional antenna is installed at a high position, it is inconvenient for staff to operate with tools.

[0004] Therefore, a high-frequency array omnidirectional antenna is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that when omnidirectional antennas need to be repaired, tools are needed to loosen the clamps and nuts, but because the omnidirectional antennas are installed at a high position, it is inconvenient for workers to operate with tools. Therefore, a high-frequency array omnidirectional antenna is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-frequency array omnidirectional antenna, comprising a housing and a mounting plate, wherein the housing contains a plurality of high-frequency vibrators, a fixing tube is fixedly mounted on the surface of the mounting plate, a connecting plate slides through the inner wall of the fixing tube, a frame is fixedly mounted on the surface of the connecting plate, a connecting plate is slidably connected to the inner wall of the frame, the connecting plate is fixedly connected to the housing, a pin slides through the frame, the pin slides through the connecting plate, a pull plate is fixedly mounted on one end of the pin, and two screws are threadedly connected inside the fixing tube.

[0007] The effect achieved by the above components is that, by setting up components such as clip frames, connecting plates and pins, when inspecting omnidirectional antennas installed on building walls at high altitudes, workers can remove the omnidirectional antennas without using tools, thus facilitating construction at high altitudes.

[0008] Preferably, a spring is fitted around the circumference of the pin, and the two ends of the spring are fixedly connected to the pull plate and the retaining frame, respectively.

[0009] The effect achieved by the above components is that when the spring contracts, the pull plate will use the spring force to drive the pin to slide through the card frame and the connecting plate.

[0010] Preferably, a round rod is fixedly mounted on the surface of the card frame, and a rotating plate is rotatably connected to the circumferential surface of the round rod.

[0011] The effect achieved by the above components is that when the side of the rotating plate away from the card frame contacts the side of the pull plate near the pin, the rotating plate can restrict the position of the pull plate, thereby restricting the position of the pin and preventing the pin from sliding due to the spring force and affecting subsequent operations.

[0012] Preferably, the connecting plate has an inclined groove at a position relative to the screw, and the vertical cross-section of the inclined groove is triangular.

[0013] The effect achieved by the above components is as follows: when the two screws abut against the inner wall of the vertical triangular groove, one groove will prevent the screw from moving upward and the other groove will prevent the other screw from moving downward. Therefore, the two grooves and the two screws can restrict the position of the frame in the vertical direction.

[0014] Preferably, a baffle is fixedly fitted to the lower end of the connecting plate.

[0015] The effect achieved by the above components is that the baffle can prevent the connecting plate from coming out of the fixed tube.

[0016] Preferably, a fixing ring is fixedly mounted on the surface of the fixing tube, a protective cover is slidably connected to the inner wall of the fixing ring, and the screw is located inside the protective cover.

[0017] The effect achieved by the above components is that the protective cover slides into the fixing ring, and the cooperation between the protective cover and the fixing ring can prevent dust and other foreign objects from adhering to the exposed section of the screw, thus protecting the screw.

[0018] Preferably, a magnetic sheet is fixedly mounted on the surface of the protective cover, and the magnetic sheet abuts against the inner wall of the fixing ring, which is an iron ring.

[0019] The effect achieved by the above components is that the magnetic sheet will adhere to the inner wall of the fixing ring, preventing the protective cover from falling off.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting components such as a frame, connecting plate, and pin, workers can remove the omnidirectional antenna installed on a high building wall without using tools when performing maintenance, thus facilitating construction at high altitudes.

[0023] 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.

[0024] 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.

[0025] like Figures 1-5 As shown, this utility model provides a high-frequency array omnidirectional antenna, including a housing 1 and a mounting plate 3. The housing 1 contains a plurality of high-frequency vibrators 2. A fixing tube 4 is fixedly mounted on the surface of the mounting plate 3. A connecting plate 5 slides through the inner wall of the fixing tube 4. A frame 6 is fixedly mounted on the surface of the connecting plate 5. A connecting plate 7 is slidably connected to the inner wall of the frame 6. The connecting plate 7 is fixedly connected to the housing 1. A pin 8 slides through the frame 6 and slides through the connecting plate 7. A pull plate 9 is fixedly mounted on one end of the pin 8. Two screws 13 are threadedly connected inside the fixing tube 4. By setting up components such as the frame 6, the connecting plate 7, and the pin 8, when inspecting the omnidirectional antenna installed on the high wall of a building, workers can remove the omnidirectional antenna without using tools, thus facilitating high-altitude construction.

[0026] like Figures 2-5As shown, a spring 10 is fitted around the circumference of the pin 8. The two ends of the spring 10 are fixedly connected to the pull plate 9 and the retaining frame 6, respectively. When the spring 10 contracts, the pull plate 9, aided by the spring's elasticity, causes the pin 8 to slide through the retaining frame 6 and the connecting plate 7. A round rod 11 is fixedly mounted on the surface of the retaining frame 6. A rotating plate 12 is rotatably connected to the circumference of the round rod 11. When the side of the rotating plate 12 away from the retaining frame 6 contacts the side of the pull plate 9 closest to the pin 8, the rotating plate 12 restricts the position of the pull plate 9, thereby restricting the position of the pin 8. To prevent the pin 8 from sliding due to the elastic force of the spring 10 and affecting subsequent operations, the connecting plate 5 has a slanted groove 14 at the position relative to the screw 13. The vertical cross-section of the slanted groove 14 is triangular. When the two screws 13 abut against the inner wall of the slanted groove 14 with the vertical cross-section of the triangular section, one slanted groove 14 will prevent the screw 13 from moving upward, and the other slanted groove 14 will prevent the other screw 13 from moving downward. Therefore, the two slanted grooves 14 and the two screws 13 can restrict the position of the frame 6 in the vertical direction.

[0027] like Figures 2-4 As shown, a baffle 15 is fixedly mounted on the lower end of the connecting plate 5. The baffle 15 can prevent the connecting plate 5 from coming out of the fixed tube 4. A fixing ring 16 is fixedly mounted on the surface of the fixed tube 4. A protective cover 17 is slidably connected to the inner wall of the fixing ring 16. The screw 13 is located inside the protective cover 17. The protective cover 17 slides into the fixing ring 16. The cooperation between the protective cover 17 and the fixing ring 16 can prevent dust and other foreign objects from adhering to the exposed section of the screw 13 and protect the screw 13. A magnetic sheet 18 is fixedly mounted on the surface of the protective cover 17. The magnetic sheet 18 abuts against the inner wall of the fixing ring 16. The fixing ring 16 is an iron ring. The magnetic sheet 18 will be attracted to the inner wall of the fixing ring 16 to prevent the protective cover 17 from falling off.

[0028] The overall working principle is as follows: When installing the high-frequency array omnidirectional antenna, firstly, use expansion bolts to fix the mounting plate 3 to a suitable position on the wall. Then, pull the protective cover 17 to separate the magnetic sheet 18 from the fixing ring 16, remove the protective cover 17 to expose the screw 13, and then slide the connecting plate 5 along the inner wall of the fixing tube 4. The connecting plate 5 will drive the frame 6 to move, adjusting the height of the frame 6. During this process, the baffle 15 can prevent the connecting plate 5 from coming out of the fixing tube 4. After adjustment, rotate the screw 13. When the two screws 13... After the screws 13 are respectively pressed against the inner walls of the triangular vertical grooves 14, one groove 14 will prevent the screw 13 from moving upward, and the other groove 14 will prevent the other screw 13 from moving downward. Therefore, the two grooves 14 and the two screws 13 can restrict the position of the frame 6 in the vertical direction. Then, the protective cover 17 is slid into the fixing ring 16. The protective cover 17 and the fixing ring 16 cooperate to prevent dust and other foreign objects from adhering to the exposed section of the screw 13, thus protecting the screw 13. The magnetic sheet 18 will be attracted to the inner wall of the fixing ring 16 to prevent the protective sheet from being attached. If cover 17 falls off, pull plate 9 is pulled. Pull plate 9 will cause pin 8 to slide and stretch spring 10. Then rotate rotating plate 12. When the side of rotating plate 12 away from frame 6 contacts the side of pull plate 9 near pin 8, rotating plate 12 can restrict the position of pull plate 9, thereby restricting the position of pin 8 and preventing pin 8 from sliding due to the elastic force of spring 10, which would affect subsequent operations. Then move outer shell 1 to slide connecting plate 7 along the inner wall of frame 6. Then rotate rotating plate 12 to disengage rotating plate 12 from pull plate 9. When the spring 10 contracts, the pull plate 9 will use the elastic force of the spring 10 to drive the pin 8 to slide through the frame 6 and the connecting plate 7. The pin 8 will limit the position of the connecting plate 7, and the installation of the omnidirectional antenna can be completed. When the omnidirectional antenna needs to be inspected, pull the pull plate 9 again to pull out the pin 8 and use the rotating plate 12 to limit the pull plate 9. Then the outer shell 1 can be moved upward to pull the connecting plate 7 out of the frame 6, so as to remove the omnidirectional antenna. No additional tools are needed in this process, which is convenient for high-altitude construction.

[0029] 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 present utility model.
