It is exemplary, it is intended to for explaining the utility model, and it is not intended that to limitation of the present utility model.It is new based on this practicality
Embodiment in type, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belong to the scope of the utility model protection.Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer " is based on accompanying drawing institutes
The orientation or position relationship shown, it is for only for ease of description the utility model and simplifies description, rather than indicates or imply and be signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The limitation of novel protected scope.
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, refers to Fig. 1 to Fig. 5；
As shown in Figures 1 and 2：A kind of multi-rotor unmanned aerial vehicle horizontal folding mechanism, including：Four cantilevers 1 and with four it is outstanding
Four folding shafts 2 and four screw rods 4 that arm 1 matches；
Four cantilevers 1 are distributed on body surrounding, and each cantilever 1 is mounted on cantilever two about 1 by a folding shaft 2
Between the installing plate 3 of side, and plate 3 is mounted opposite without relative rotation.
As shown in Figure 3：The surface of screw rod 4 is provided with motion thread, and upper and lower two installing plates 3 are provided with what is coordinated with screw rod 4
Screwed hole, the both ends of screw rod 4 are coordinated with installing plate 3 by screw thread respectively is installed, and screw rod 4 can be made to be arranged on upper lower installation board 3；
The both ends of screw rod 4 are connected by screw thread with installing plate 3, can be mounted opposite plate 3 and be rotated.
As shown in Figure 4：Part of the screw rod 4 between two installing plates 3 is disposed with two opposite lockings of thread rotary orientation
Sliding block 5, two locking sliding blocks 5 can be in opposite directions or away from moving along screw rod 4.
Cantilever 1 is provided with limiting stand 6, between rotating cantilever 1 and falling into two locking sliding blocks 5 by limiting stand 6, now turns
