Description

Technical Field

[0001] The present invention relates to the technical field of ceiling antennas, and more particularly to a broadband directional ceiling antenna. Background Art

[0002] Indoor antennas use a distributed antenna system within a building to transmit mobile communication signals through antenna feed lines to every corner of the building, thereby solving the problem of weak indoor signal strength and poor quality. At the same time, they share the call traffic borne by base station antennas, help solve the problem of mutual interference in signal field strength, and avoid network congestion caused by too many users.

[0003] Ceiling antennas are usually installed on the top of a room. When installing a broadband ceiling antenna, it is usually installed close to the ceiling. However, in scenarios such as factories where no ceiling is installed, L-shaped corner brackets are often used for installation. When installing the L-shaped corner brackets, the corner brackets are usually fixed to the top of the ceiling antenna first, and then holes are drilled in the ceiling with a punching tool, and fixed to the ceiling with auxiliary fixing parts such as bolts. However, since the length of the vertical plate of the L-shaped corner bracket is limited, the L-shaped corner bracket will greatly affect the appearance and waste space when the vertical plate is long, and increase the risk of being hit when carrying large items. Therefore, in actual installation, when the L-shaped corner brackets are installed on the ceiling with bolts, the space is limited, and it is difficult or even impossible to tighten the bolts with power tools. Usually, the operation is performed directly with simple tools such as wrenches, and the field of view and operating space are limited during the operation, which makes many inconveniences in the installation.

The installer does not need to manually connect the bolts to the directional ceiling antenna, saving work steps.

[0023] The cleaning plate 403 described in the article is made of flexible rubber and a cleaning cloth is tied to the surface. The whole body can be deformed. The height of the lower horizontal plate of the hook 406 is lower than the fixing ring 404, and the length of the horizontal plate of the hook 406 is smaller than the bayonet 405. At the same time, the shielding shell 407 is made of aluminum alloy.

[0024] Working principle: A broadband directional ceiling antenna, when installed in a room without a ceiling, such as a factory, first place the additional mounting plate 1 above the conventional mounting plate 2, and place the connecting bolt 301 inside the embedded groove 3, then rotate the connecting bolt 301, and connect the additional mounting plate 1 with the conventional mounting plate 2 by means of the connecting bolt 301, then insert the plug-in board 102 into the U-shaped connecting plate 101, and connect the U-shaped connecting plate 101 with the plug-in board 102 by means of the fixing bolt 107, then rotate the two fixing bolts 107 located on the rotating shaft 103, and the fixing bolts 107 gradually move away from the stabilizing plate 108 and the rubber pad 112 after the stabilizing plate 108 and the rubber pad 112 are separated from the fixing bolts 107 The lock is released, so that the connecting sleeve 104 can slide freely on the outer surface of the rotating shaft 103, and then the vertical plate 105 is rotated to make the vertical plate 105 tend to be horizontal. After the vertical plate 105 rotates, the force-bearing plate 109 is rotated synchronously, and the wide surface of the force-bearing plate 109 is at the top. At this time, the force-bearing plate 109 is vertically offset from the ceiling antenna as a whole. Then, the lower fixing bolt 107 is rotated again to re-lock the lower rotating shaft 103 and the lower connecting sleeve 104. Since the force-bearing plate 109 is offset from the ceiling antenna at this time, sufficient space is left for operation. After the installation is completed, the lower rotating shaft 103 and the connecting sleeve 104 are unlocked, and the ceiling antenna as a whole is pulled downwards so that the vertical plate 105 is in a vertical state, and then the upper and lower fixing bolts are re-assembled. The two fixing bolts 107 are tightened to complete the installation. At the same time, before installation or after disassembly, the cable 5 can be wound around the outer surfaces of the two threaded cylinders 305, and the winding range of the cable 5 can be limited by the limiting plate 304, and the cable 5 can be pressed by the downward movement of the limiting plate 304 to prevent it from loosening and detaching. When installing in a room with a suspended ceiling, the limiting plate 304 can be first rotated to disengage from the threaded cylinder 305, and then the connecting bolts 301 can be removed, and the additional installation plate 1 can be disassembled as a whole, and then holes that are compatible with the threaded cylinder 305 can be drilled in the suspended ceiling, and the threaded cylinder 305 can be extended to the top of the suspended ceiling through the holes. At this time, the limiting plate 304 is screwed into the outer surface of the threaded cylinder 305 again, and the limiting plate 304 and the threaded cylinder 305 are used to fix the ceiling. The wire is fixed as a whole, and when adjusting the direction of the main lobe of the broadband directional antenna 203, first rotate the closing disk 420 so that the limit block 419 on the closing disk 420 is aligned with the inlet 418, and then pull the closing disk 420 downward to disengage the closing disk 420. At this time, pinch the cross bar 410 to rotate the adjusting disk 408. When the adjusting disk 408 rotates, the limiting ring 414 is used to limit its own movement trajectory, and when the adjusting disk 408 rotates, the shielding shell 407 is synchronously driven to rotate. When the shielding shell 407 rotates, it will synchronously drive the broadband directional antenna 203 to rotate through the connecting rod 422, thereby adjusting the direction of the broadband directional antenna 203, and the direction of the main lobe of the broadband directional antenna 203 can be intuitively observed with the help of the direction of the cross bar 410.The shielding shell 407 can be used to weaken the signal strength in the directional direction, and the directional opening 411 on the shielding shell 407 can be used to increase the signal capability of the broadband directional antenna 203. When the broadband directional antenna 203 is in a smoke environment and has a certain amount of dirt or smoke particles attached to the surface, cleaning liquid can be added to the inside of the inclined rod 401 through the filling port 402. After the cleaning liquid is added, it is absorbed by the cleaning cloth on the cleaning plate 403, and then the fixing ring 404 is rotated. When the fixing ring 404 rotates, it will synchronously drive the two inclined rods 401 and the cleaning cloth to rotate. The cleaning plate 403 rotates, and then the outer surface of the antenna protective shell 201 is cleaned with the help of the cleaning plate 403 and the cleaning liquid. At the same time, when the cleaning plate 403 is removed to clean it, the fixing ring 404 is also rotated until the bayonet 405 on the fixing ring 404 is aligned with the hook 406. At this time, the fixing ring 404 is pulled downward to drive the cleaning plate 403 to separate from the inclined rod 401. Because the cleaning plate 403 and the cleaning cloth set thereon are both made of flexible materials and can be deformed, they will not get stuck when being pulled out.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
