Description

Technical Field

[0001] The utility model belongs to the technical field of communication antennas, and specifically provides a communication antenna convenient for roof installation. Background Art

[0002] In related technical solutions, a communication antenna (such as a base station antenna) is installed on the top of a building (i.e., the roof). The communication antenna includes an antenna body and a mounting rack for supporting the antenna body. The mounting rack includes a flat bottom plate, and a vertical rod is fixedly arranged on the bottom plate perpendicularly. The antenna body is fixedly arranged at the top of the vertical rod. Here, the bottom plate is placed flat and attached to the upper surface of the roof. After leveling the bottom plate by using leveling bolts, the bottom plate and even the entire mounting rack are fixed to the roof by using expansion bolts penetrating into the roof.

[0003] The inventor has learned that in related application scenarios, green plants or waterproof coiled material structures need to be arranged on the upper surface of the roof, and thus it is not convenient to fix the mounting rack of the communication antenna to the upper surface of the roof by using expansion bolts. At this time, generally, the bottom of the mounting rack is fixed at the position of the roof parapet wall (i.e., the daughter wall) or the corner position between the roof and the outer wall. The bottom plate at the lower part of the existing communication antenna cannot adapt to the installation of different application scenarios at the same time, and different types of bottom plates need to be adapted according to the installation position, which is a cumbersome process and different specifications of bottom plates need to be produced. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a communication antenna convenient for roof installation, which can solve at least one of the above technical problems.

[0005] In order to solve the above problems in the prior art, one or more embodiments of the utility model provide a communication antenna convenient for roof installation, including an antenna body, a vertical rod and a bottom plate assembly. The bottom plate assembly is used for fixing to the roof. The lower part of the vertical rod is connected with the bottom plate assembly, and the antenna body is installed on the upper part of the vertical rod. The bottom plate assembly includes a main board and two side boards respectively rotatably installed on both sides of the main board. The rotation axes of the two side boards are parallel to each other and perpendicular to the vertical rod. The bottom plate assembly has a planar state, a U-shaped state and a corner state.

[0006] In the planar state, the two side boards rotate to be flush with the main board, and the side board and the main board can be respectively fixed to the upper surface of the roof. In the U-shaped state, the two side boards rotate downward to be perpendicular to the main board, and a wall board space is enclosed between the two side boards for inserting and fixing the roof parapet wall. In the corner state, one of the two side boards rotates to be flush with the main board, and the other rotates to be perpendicular to the main board, and the bottom plate assembly can be attached to and fixed to the corner between the roof and the outer wall.

[0007] The beneficial effects of the above one or more technical solutions:

[0008] The bottom plate assembly in this solution includes a main board and two side plates rotatably installed on both sides of the main board. The two side plates can independently rotate relative to the main board to be flush with or perpendicular to the main board, so that the bottom plate assembly can be in a flat state, a U-shaped state, and a corner state. Therefore, this solution facilitates directly installing the bottom plate assembly of the communication antenna on the upper surface of the roof, the cornice wall on the roof, or the corner position between the roof and the outer wall. That is, this solution facilitates installing the bottom plate at different positions on the roof by deforming the bottom plate assembly, without the need to manufacture bottom plates of different shapes for replacement, which is convenient for installing the communication antenna at different positions on the roof and improves the usage range of the bottom plate assembly.

[0017] As Figures 1-3 shown, a communication antenna convenient for roof installation provided in this embodiment includes an antenna body 3, a vertical pole 1, and a bottom plate assembly 4. The bottom plate assembly 4 is used to be fixed to the roof. The lower part of the vertical pole 1 is connected to the bottom plate assembly 4, and the upper part of the vertical pole 1 is installed with the antenna body 3. The bottom plate assembly 4 includes a main board 401 and two side plates (i.e., the first side plate 402 and the second side plate 403 shown in the figure) respectively rotatably installed on both sides of the main board 401. The two side plates are respectively rotatably connected to the main board through a rotating shaft 404, and the rotation axes are parallel to each other and perpendicular to the vertical pole 1. The bottom plate assembly 4 has a flat state, a U-shaped state, and a corner state. In the flat state, the two side plates rotate to be flush with the main board 401, and the side plates and the main board 401 can be respectively fixed to the roof surface 6 (i.e., the horizontal or substantially horizontal upper surface on the roof). In the U-shaped state, the two side plates rotate downward to be perpendicular to the main board 401, and a wall board space is enclosed between the two side plates, and the wall board space is used to insert and fix the cornice wall 5 on the roof. In the corner state, one of the two side plates rotates to be flush with the main board 401, and the other rotates to be perpendicular to the main board 401, and the bottom plate assembly 4 can be attached to and fixed to the corner of the roof surface 6 and the outer wall surface 7.

[0018] Specifically, the antenna body 3 here can be a 5G base station antenna, a 4G base station antenna, etc. The antenna body 3 is used to be erected on the roof of a building to increase its own installation height and reduce the interference of surrounding buildings, etc. That is, the specific structural form and function of the communication antenna in this embodiment are not limited and can be set by those skilled in the art according to needs.

[0019] The vertical pole 1 in this embodiment is a vertically arranged rod, and the vertical pole 1 enables the antenna body 3 to be suspended relative to the bottom plate assembly 4 and the roof, further increasing the installation height of the antenna body 3.

[0020] Specifically, the main board 401 and the side boards here can be three board members with the same structural form and size. When the two side boards are rotated to be flush with the main board 401, the main board 401 and the side boards are combined into an integral square board member. In some other embodiments, the sizes of the main board 401 and the side boards can also be different, only the shapes and sizes of the two side boards are the same; or the sizes between the two side boards and the main board 401 are all different.

[0021] In this embodiment, first through holes 405 are respectively provided on the main board 401 and the side boards. Expansion bolts 409 are provided at the first through holes 405, and the main board 401 and the side boards are fixed to the roof and / or the eaves wall 5 and / or the outer wall surface 7 through the expansion bolts 409.

[0022] In this embodiment, it also includes angle irons and connecting bolts (not shown in the figure). The angle irons and the connecting bolts can fix the main board 401 and the adjacent side boards. Specifically, the angle iron includes a first plate and a second plate that are perpendicular to each other. Two connecting holes are provided on the first plate, and a single connecting hole is provided on the second plate. When the main board 401 and the side boards are perpendicular to each other, the connecting holes on the main board 401 and the side boards are respectively aligned with the connecting holes on the first plate and the second plate, and then the connecting bolts are inserted into the two aligned connecting holes. When the main board 401 and the side boards are rotated to be flush, the connecting holes on the main board 401 and the side boards are respectively aligned with the two connecting holes on the first plate, and then the connecting bolts are inserted into the mutually aligned connecting holes. That is, this embodiment facilitates the reinforcement of the adjacent side boards and the main board through the angle irons and the connecting bolts.

[0023] In this embodiment, second through holes 406 are respectively provided on the two side boards; in the U-shaped state, the second through holes 406 on the two side boards are respectively aligned, and a screw rod 407 is inserted through the two mutually aligned second through holes 406. Locking nuts 408 are provided at both ends of the screw rod 407. When it is not convenient to drill holes in the eaves wall 5, this setting method can utilize the cooperation of the screw rod 407 and the locking nuts 408 to generate a large frictional force between the two side boards and the wall surface of the eaves wall 5, thereby facilitating the fixation of the bottom plate assembly 4 by using the frictional force.

[0024] In this embodiment, it also includes a plurality of flexible pads. The flexible pads are used to fill the gap between the wall board space and the eaves wall 5, and the flexible pads have mounting holes through which the screw rod 407 passes. When the flexible pads are adopted, the combination of the plurality of flexible pads 10 can make up for the gap between the distance between the two side boards and the thickness of the eaves wall 5 through the compression of the flexible pads.

[0025] In this embodiment, the main board 401 and the side boards in the bottom plate assembly 4 are both frame boards. Specifically, the frame board at least includes two longitudinal boards that are parallel to each other, and a plurality of transverse boards are connected in parallel between the two longitudinal boards.

[0026] In this embodiment, the main board 401 has a vertically arranged mounting sleeve 9, and the lower end of the vertical rod 1 can be inserted into the mounting sleeve and fixed. Specifically, the lower end of the vertical rod 1 has an external thread 8, and the mounting sleeve has an internal thread that mates with the external thread. That is, after the vertical rod 1 is screwed into the mounting sleeve in a spiral manner, the fixation of the vertical rod 1 and the bottom plate assembly 4 can be achieved. In some other embodiments, pin holes can be respectively provided at the lower end of the vertical rod 1 and the mounting sleeve. After the vertical rod 1 is inserted into the mounting sleeve, the pin holes on the vertical rod 1 and the mounting sleeve are aligned, and then a positioning pin can be inserted at the pin holes. Or, when both the vertical rod 1 and the bottom plate assembly 4 are made of metal, they can be fixed by welding.

[0027] In this embodiment, the upper end of the vertical rod 1 has a threaded section 101, and two support seats 2 are sleeved outside the threaded section 101. The support seats 2 are connected to the threaded section 101 by threads, and the support seats 2 are used to support the antenna body 3.

[0028] Specifically, the two support seats 2 are respectively sleeved outside the threaded section, so that the two support seats 2 can respectively rotate relative to the upper end of the vertical rod 1 to adjust the distance between the two mounting seats, thereby adapting to the characteristics of different lengths of the upper and lower ends of communication antennas with different sizes.

[0029] In this embodiment, the vertical rod 1 is a multi-section telescopic rod structure. Specifically, the vertical rod 1 can be telescopically adjusted in the vertical direction to adjust its own height. The vertical rod 1 includes a plurality of rod sleeves that are sequentially sleeved with each other, and a detachable positioning pin or bolt or the like can be provided between the ends of adjacent rod sleeves as a locking member.

[0030] In addition, in order to strengthen the vertical rod 1, a steel wire rope seat 11 is fixed at the top of the vertical rod 1. The steel wire rope seat 11 is fixed to the upper end of the steel wire rope 12, and the lower end of the steel wire rope 11 is fixed to the edge of the bottom plate assembly 4. A plurality of steel wire ropes 12 are arranged around the vertical rod 1, and the pulling of the steel wire ropes 12 can prevent the vertical rod from bending relative to the bottom plate assembly 4 caused by strong winds.
