arms

120, 121, and one arm 121 of the telescoping mechanism 12 is fixed to a fixed side 1102 of the rotating base 113. Two

Specifically, the lower pole embracing base 21 includes a front end clamping plate 210 and a rear end clamping plate 212 (for the sake of distinction from the front end clamping plate and the rear end clamping plate of the upper pole embracing base 11, the front end clamping plate 210 and the rear end clamping plate 212 included in the lower pole embracing base 21 are hereinafter referred to as a lower front end clamping plate 210 and a lower rear end clamping plate 212, respectively).

The lower front end plate 210 includes a pendulum bottom surface 2100 and side surfaces 2101. The side surface is provided with a notch matching with the shape of the antenna mast 3 at one end facing the direction of the antenna mast 3, so that the lower front end clamping plate 210 holds the antenna 3 through the notch and fixes the lower front end clamping plate 210 to the antenna mast 3 by combining with other accessories such as the lower rear end clamping plate 212 and the bolt 5. In some embodiments, the pendulum bottom surface 2100 is rectangular and has an elongated arcuate bend 220 along its surface length. The curved path 220 may be integrally formed on the lower front end plate 210.

The tilting mechanism 22 includes an arc-shaped curved path 220 provided on the lower front end clamp plate 210 of the lower holding bar base 21, and a fixing member 221 for fixing the arc-shaped curved path 220 at any position thereof.

The fixing member 221 includes a fixing bottom surface 2210 and two side surfaces 2211, and the fixing bottom surface 2210 and the two side surfaces 2211 form an angle arm structure. As shown in fig. 6, the fixing bottom surface 2210 is provided with at least two through holes 2212. The fixing bottom surface 2210 of the fixing member 221 is fixedly installed opposite to the pendulum bottom surface 2100 of the lower front end clamp 210, a bolt 5 passes through the through hole 2212 and the curved bend 220, the bolt 5 is fastened by a nut 7 at the other side of the pendulum bottom surface 2100, so that the fixing member 221 is fixed to the surface of the lower front end clamp 210 of the lower holding bar seat 21, and the bolt shaft of the bolt 5 is located in the curved bend 220 of the lower front end clamp 210. The width of the curved bend 220 is smaller than the width of the fixing bottom 220 of the fixing member 221, and the curved bend is adapted to the bolt shaft of the bolt 5. A certain loosening margin is provided between the fixing member 221 and the lower holding pole seat 21, so that the fixing member 221 can tilt and swing back and forth along the arc-shaped curve 220 of the lower holding pole seat 21 through the bolt 5. When the fixing member 221 slides to the extreme edge of the curved curve 220, the bolt 5 is caught by the edge of the curved curve 220, so that the fixing member 221 cannot slide any more, and therefore the curved curve 220 limits the moving range of the fixing member 221. In addition, the fixing member 221 may be locked at any position of the tilting movement stroke defined by the curved curve 220.

The two side surfaces 2211 of the lower fixing element 221 are used for being fixed with the lower end of the antenna 4, the lower fixing element 221 can drive the lower end of the antenna 4 to perform a tilting motion along the arc-shaped curve 220, the arc-shaped curve 220 defines a tilting motion stroke of the lower end of the antenna 4, and the lower fixing element is locked in any position of the defined tilting motion stroke. The telescoping mechanism 12 and the lower fixing member 221 are fixed to the corresponding mounting parts of the upper end of the antenna 4 and the lower end of the antenna 4 by bolts 5, respectively.

The antenna mounting structure provided by the invention is characterized in that the upper mounting component 1 is matched with the lower mounting component 2, and the tilting mechanism 22 controls the antenna 4 to rotate around the telescopic mechanism 12 along the tilting movable stroke of the tilting mechanism, so that the mechanical tilt angle adjustment of a pendulum type antenna is realized.

Referring to fig. 1, the upper pole embracing base 11 and the telescopic mechanism 12 of the upper mounting assembly 1 are fixed to the upper end of the antenna 4, so that the upper end of the antenna 4 is fixedly connected to the telescopic mechanism 12, the upper end of the antenna 4 moves along with the telescopic mechanism 12 within the telescopic range, and is locked at any position within the telescopic range to determine the mechanical tilt angle of the antenna 4, and the mechanical tilt angles corresponding to different pitches are locked at different positions, which can be specifically adjusted according to requirements.

The lower end of the antenna 4 is connected with the fixing piece 221 of the lower mounting component 2 by taking the position where the upper end point of the antenna 4 stays in any position of the telescopic range as a fixed point, and the antenna 4 is locked at any position of the arc-shaped curve 220 along with the inclination of the arc-shaped curve 220. Therefore, after the upper end position of the antenna 4 is fixed, that is, in the case where the angle at which the antenna 4 is tilted is determined, the orientation of the antenna 4 can also be changed by swinging the position of the lower end of the antenna 5. Through the cooperation of the upper mounting component 1 and the lower mounting component 2, the antenna 4 can be adjusted in the direction angle of the antenna within the range of each inclination angle defined by the telescopic mechanism 12 through a pendulum, so that the signal coverage requirements of different angles can be met, and particularly the signal coverage requirements of the antenna 4 on a specific target object can be met.

The geometric circle center of the arc-shaped bend 220 is located in the area range where the accessories of the upper pole embracing seat 11 are located, so that the lower end of the lower antenna 4 connected with the lower pole embracing seat 21 can rotate in a limited range circumferentially by taking a connection point at the upper end of the antenna 4 connected with the upper mounting assembly 1 as the circle center. When the antenna 4 needs to adjust its tilt angle, the fixing member 221 is adjusted to a corresponding tilt position and then locked.

In addition, because the arc groove 1134 is formed in the rotating base 113 connected to the retractable mechanism 12 at the upper end of the antenna 4, when the lower end of the antenna 4 tilts along the arc-shaped curved channel 220, the fixed point at the upper end of the antenna 4 can have a certain rotation margin under the limitation of the arc groove 1134, so that the flexibility of the antenna 4 in pendulum motion is improved, and the service life of each accessory is prolonged.

The antenna mounting structure provided by the invention has the advantages that the upper mounting component 1 is matched with the lower mounting component 2, so that the antenna can realize 'pendulum type' mechanical inclination angle adjustment in the vertical direction, and the signal coverage requirement of an antenna directional diagram on a specific target object is met.
