DETAILED DESCRIPTION

Specific embodiments of the present invention will be described below in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to describe and explain the present invention, and are not used to limit the present invention.
Fig. 1 is a schematic diagram of an antenna apparatus provided in a comparative example installed on a support rod. As shown in Fig.1, an antenna apparatus 10 is installed on a support rod 20 by means of an antenna installation apparatus. The antenna installation apparatus includes: a connection assembly 30, and a first sheathing assembly 40 and a second sheathing assembly 50 which are sheathed on the support rod 20. The connection assembly 30 is installed on the first sheathing assembly 40, and the antenna apparatus 10 is connected to the connection assembly 30 and the second sheathing assembly 50. The connection assembly 30 includes two first connection arms 31 and a second connection arm. The first connection arms 31 are connected to the first sheathing assembly 40. By adjusting an included angle between each first connection arm 31 and the second connection arm, an installation angle of the antenna apparatus may be adjusted. Fig. 2 is a schematic diagram showing the connection between the first connection arms of the connection assembly and the first sheathing assembly provided in the comparative example. As shown in Fig. 2, a convex portion 40a is arranged at the right side of the first sheathing assembly 40, each first connection arm 31 is arranged on the convex portion 40a by means of screws or other fastening structures, and a certain distance is kept between the first connection arm 31 and the first sheathing assembly 40, so that the first connection arm 31 may be adjusted to different angles. In addition, the convex portion 40a also has a large width, which leads to a large distance dl between the antenna apparatus 10 and the support rod 20.
In an installation scenario of a narrow space, for example, when the antenna apparatus 10 is installed in a beautification hood, if the distance between the antenna apparatus 10 and the support rod 20 is large, the antenna apparatus 10 is nearly attached to the wall surface of the beautification hood closely, resulting in the following problems: limited operation space for installation, great difficulty in installation; difficult adjustment of antenna angles (for example, an azimuth angle and a dip angle), which affects a signal coverage direction; and small remaining space in the beautification hood, which affects an air duct and is not beneficial to heat dissipation of an antenna.
An embodiment of the present invention provides an antenna installation apparatus. The antenna installation apparatus includes: a first sheathing assembly, a connection assembly and an installation assembly. Fig. 3 is a schematic diagram showing a first connection state of a first sheathing assembly, a connection assembly and an installation assembly provided in some embodiments of the present invention; and Fig. 4 is a schematic diagram showing a second connection state of a first sheathing assembly, a connection assembly and an installation assembly provided in some embodiments of the present invention. As shown in Figs. 3 and 4, the first sheathing assembly 40 is configured to be sheathed on the support rod, the installation assembly 60 is located at one side of the first sheathing assembly 40 in a predetermined direction, one end of the connection assembly 30 is connected to the installation assembly 60, and the other end of the connection assembly 30 is configured to be connected to an antenna apparatus. The predetermined direction is a length direction of the support rod. "The installation assembly 60 is located at one side of the first sheathing assembly 40 in a predetermined direction", that is, when the first sheathing assembly 40 is sheathed on the upright support rod, the installation assembly 60 is located above or below the first sheathing assembly 40.
In an embodiment of the present invention, the installation assembly 60 is located above or below the first sheathing assembly 40, one end of the connection assembly 30 is connected to the installation assembly 60, and the other end of the connection assembly is connected to the antenna apparatus. Compared with the way of connecting the connection assembly 30 to the convex portion 40a at the right side of the first sheathing assembly 40 in Fig. 2, in the antenna installation apparatus of the embodiment of the present invention, no gap is kept between the connection assembly 30 and the first sheathing assembly 40 in a horizontal direction, and moreover, when the first sheathing assembly 40 is sheathed on the support rod, even if the width of the installation assembly 60 is large, the distance between the antenna apparatus and the support rod cannot be increased, so that the antenna apparatus may be closer to the support rod, which is beneficial to the installation of the antenna apparatus in a narrow space.
In some embodiments, as shown in Fig. 3, the installation assembly 60 includes an installation shaft 61, installation plates 62 located at both sides of the installation shaft 61 in an axial direction, and first locking components 63 arranged on the installation plates 62.
Fig. 5 is a schematic diagram of the connection assembly shown in Fig. 4. Referring to Figs. 3 to 5, the connection assembly 30 includes: a first connection arm 31 and a second connection arm 32. The first end of the first connection arm 31 is fixedly connected to the installation shaft 61, the second end of the first connection arm 31 is rotatably connected to the first end of the second connection arm 32, and the second end of the second connection arm 32 is configured to be connected to the antenna apparatus. The first locking components 63 are configured to keep the installation shaft 61 and the installation plates 62 relatively fixed when a first target angle is formed between a length direction of the first connection arm 31 and the predetermined direction. The length direction of the first connection arm 31 refers to a direction from the first end to the second end of the first connection arm 31. The first target angle may be set as required.
The second end of the second connection arm 32 may be indirectly connected to the antenna apparatus. For example, as shown in Figs. 3 and 5, the connection assembly 30 further includes a first support base 33, and the second end of the second connection arm 32 is indirectly connected to the antenna apparatus by means of the first support base 33.
Fig. 6 is a schematic diagram showing the connection between the first connection arm and the installation shaft provided in some embodiments of the present invention. As shown in Fig. 6, the end faces of both ends of the installation shaft 61 are provided with a threaded hole 61v respectively, and the installation plates 62 are provided with a through hole 62v respectively (as shown in Fig. 10). The threaded hole 61v in the installation shaft 61 is directly opposite to the through hole 62v in the installation plates 62. The first locking component 63 shown in Fig. 3 includes a screw that passes through the through hole 62v and is screwed into the threaded hole 61v. During the installation of the antenna apparatus, the threaded hole 61v in the installation shaft 61 is aligned with the through hole 62v in the installation plates 62, and the first connection arm 31 is rotated to an appropriate angle. Then, the first locking component 63 is screwed into the threaded hole 61v, so that the two installation plates 62 press the installation shaft 61 therebetween.
The first connection arm 31 is a sheet-metal structural component, including: a first main plate portion 311 and two first side plate portions 312. The two first side plate portions 312 are arranged at both sides of the first main plate portion 311 in a width direction, and are integrally connected with the first main plate portion 311. It should be understood that the first main plate portion 311 does not necessarily have a full-face structure, for example, the first main plate portion 311 may be provided with a hollow pattern. One end of the first main plate portion 311 is connected to the installation shaft 61, for example, the first main plate portion 311 may be connected to the installation shaft 61 by connection components 311a such as revolving rivets.
Fig. 7 is a schematic structural diagram of a second connection arm provided in some embodiments of the present invention. The second connection arm 32 is also a sheet-metal structural component. As shown in Fig. 7, the second connection arm 32 includes: a second main plate portion 321 and two second side plate portions 322. The two second side plate portions 322 are located at both sides of the second main plate portion 321 in a width direction, and the first connection arm 31 is rotatably connected to the second side plate portion 322. In this way, when an included angle between the first connection arm 31 and the second connection arm 32 is zero (that is, the first main plate portion 311 is parallel to the second main plate portion 321), the first connection arm 31 is embedded between the two second side plate portions 322 of the second connection arm 32, thus making the structure of the connection assembly 30 more compact.
Referring to Figs. 5 to 7, the first connection arm 31 is rotatably connected to the corresponding second side plate portion 322 by a revolving rivet 34. For example, the first side plate portion 312 is provided with a through hole 121, the second side plate portion 322 is provided with a through hole 3221, and the first connection arm 31 and the second connection arm 32 are rotatably connected by a revolving rivet 34 penetrating through the through hole 3121 and the through hole 3221. The method of rotationally connecting the first connection arm 31 and the second connection arm 32 by the revolving rivet 34 is easy to realize and is low in cost.
In addition, the second side plate portion 322 is provided with an arc-shaped hole 3222. The first connection arm 31 is provided with a second locking component 35. The second locking component 35 passes through the arc-shaped hole 3222. The second locking component 35 is configured to slide along the arc-shaped hole 3222 when the first connection arm 31 and the second connection arm 32 rotate relatively, and keep the first connection arm 31 and the second connection arm 32 relatively fixed when a second target angle is formed between the first connection arm 31 and the second connection arm 32. The first target angle and the second target angle may be set according to a tilt angle required by the antenna apparatus. The tilt angle range of the antenna apparatus may be limited by means of the arc-shaped hole 3222 and the second locking component 35.
In an example, the second locking component 35 is a screw, a nut 36 is fixed on the inner side of the first side plate portion 312, a through hole 3122 is formed in a position, directly opposite to the nut 36, of the first side plate 312, and the second locking component 35 passes through the arc-shaped hole 3222 and the through hole 3122 and is connected to the nut 36. If the second locking component 35 and the nut 36 are screwed, the first connection arm 31 and the second connection arm 32 are kept relatively fixed.
