In the present embodiment, the antenna stand includes the base 1, the rotating member 3, and the locking member 9, wherein the rotating member 3 is hinged in the base 1 to be rotatable between a vertical state and a horizontal state, the locking member 9 is mounted on the rotating member 3 to be rotatable in synchronization with the rotating member 3, and also has a function of locking the rotating member 3. Since the fixed part of the antenna bracket is the base 1, the locking member 9 needs to be matched with the base 1 to achieve locking, and can be realized by a locking pin or a jack. When the rotation member 3 and the locking member 9 are rotated synchronously to the vertical state, the locking member 9 is adjusted to lock the rotation member 3, and at this time, the antenna mounted on the mounting portion of the locking member 9 is in a normal operation state. When the locking piece 9 unlocks the rotating piece 3, the rotating piece 3 and the locking piece 9 can synchronously rotate to a horizontal state, and at the moment, the antenna installed on the installation part is in a folded storage state.

Because of the different unmanned aerial vehicle antenna installation environments of needs adaptation, when the antenna is folding, need have the headroom in the horizontal direction. For this purpose, in this embodiment, a adapting piece 12 is installed at the lower end of the base 1, and the adapting piece 12 is fixedly connected with the lower end of the base 1, specifically, may be fixed by screws or welding. The edge of the switching piece 12 is provided with an arc-shaped mounting hole 13 along the circumference thereof, and the mounting hole 13 can be matched with a corresponding mounting piece in a plurality of angles so as to fix the switching piece 12 on the unmanned aerial vehicle, and then the antenna bracket can be fixed on the unmanned aerial vehicle in a plurality of angles. When the antenna is actually installed, the installation angle of the antenna bracket is adjusted according to the direction of the clearance area on the unmanned aerial vehicle, so that the antenna can not be interfered when being folded.

The rotatory folding after rotating member 3 and base 1 cooperation realization antenna installation has been reached to this embodiment, the locking after rotating member 3 rotatory expansion is by locking piece 9, the purpose that is a plurality of installation angles is provided for base 1 to the mounting hole 13 that is curved on the usable change piece 12 when the installation, thereby realized making this folding antenna support have a plurality of installation angles, can adapt to the technological effect of the unmanned aerial vehicle installation environment of multiple type, and then the installation angle of collapsible antenna support is fixed in the correlation technique has been solved, the unable problem of the unmanned aerial vehicle installation environment of different grade type of adaptation.

Specifically, it should be noted that the safety lever 5 is mounted on a side of the rotating member 3 near the folding direction, and when the rotating member 3 is unfolded, the rotating member 3 receives an elastic force rotating toward the folding direction under the action of the elastic member. The rotating member 3 is locked by the locking member 9 so as not to be actively folded by the elastic force. When the rotating piece 3 is unfolded, the safety compression bar 5 can be adjusted to rotate 180 degrees until the lower end of the safety compression bar 5 abuts against the supporting surface. In this embodiment, the supporting surface is an assembly surface on which the antenna mount is mounted on the unmanned aerial vehicle. At this time, since the safety lever 5 abuts against the support surface, the folding rotation of the rotating member 3 by the elastic force can be restricted, and even if the locking member 9 is disengaged from the locking position, the rotating member 3 can be held in the extended position. In the present embodiment, the connection seat 4 disposed at the side of the rotation member 3 includes two connection lugs, and the upper end of the safety lever 5 is hinged between the two lugs.

In order to facilitate the automatic resetting of the rotating member 3, in this embodiment, a seismograph elastic member is further provided, and the first elastic member 11 can drive the rotating member 3 to rotate and reset after the locking member 9 is separated from the groove 2.

The base 1 serves as a supporting structure on which a structure for rotational connection with the rotary member 3 is provided, for example, two side plates disposed opposite to each other. The rotating member 3 and the base 1 may be connected by a known technique, for example, a hole of the rotating shaft 10 is formed on the side plates, and two ends of the rotating shaft 10 extend from two opposite sides of the rotating member 3 and are respectively inserted into the holes of the rotating shaft 10 on the two side plates. The rotating shaft 10 may be fixed to the base 1 and rotationally connected to the rotating member 3, or the rotating shaft 10 may be fixed to the rotating member 3 and rotationally connected to the base 1, or the rotating shaft 10 may be rotationally connected to the base 1 and the rotating member 3, respectively.

The rotating member 3 is further provided with a second through hole for mounting the locking member 9, which penetrates the rotating member 3 and forms openings on opposite sides of the rotating member 3. The locking member 9 of the present embodiment may be an elongated rod, and the locking member 9 is inserted into the second through hole in a clearance fit or transition fit manner, so that the locking member 9 can slide in the second through hole. The upper end of the locking piece 9 can extend upwards from the second through hole, and the lower end of the locking piece 9 can extend downwards from the second through hole after sliding downwards for a set distance. In other embodiments, the locking element 9 may have other shapes, provided that it has an end portion which protrudes from the inside of the rotating element 3 and which can be engaged with the recess 2 in a plug-in manner. The connection mode of the locking member 9 and the rotating member 3 is not limited to the above, and any structure that enables the locking member 9 to rotate synchronously with the rotating member 3 and to slide independently with respect to the rotating member 3 may be used.
