There is through-hole.
The limiting device includes the vertical plate and stop collar of two loops；Two enclose vertical plates for concentric structure, between vertical plate
There are gap, the height of the vertical plate of inside is higher than the vertical plate in outside；The part that the vertical plate of inside is higher than on the vertical plate in outside is set
There is external screw thread, stop collar is corresponding with the vertical plate of inside, and internal screw thread is equipped with inside stop collar, the form peace that stop collar is threadedly coupled
On the vertical plate of inside；Perforative strip through-hole is equipped at the telescopic rod center；On the vertical plate with through-hole two sides
The corresponding position of telescopic rod be equipped with perforative through slot；The tail portion and middle part of the telescopic rod be equipped with through slot and vertical plate it
Between the corresponding limit plate in gap.
The front end of the support arm is equipped with articulated section, and articulated section is articulated with the end of support arm；The L-type deck is located at hingedly
The lower section in portion；Articulated section front end is equipped with arc groove corresponding with motor cabinet.
Further, the gap between less than two vertical plates of the end face width of the stop collar.
The utility model has the advantages that by adopting the above technical scheme
This unmanned plane skeleton uses telescopic rotor support arm structure, is on the one hand convenient for taking after shrinking unmanned plane
On the other hand band and preservation are equipped with corresponding through-hole on skeleton, largely reduce the weight of skeleton entirety, can
Enhance the carry ability in unmanned plane later period.
Telescopic devices will not go out in the handling process in later period equally there is also skeleton structure after contraction is compact
The phenomenon that now loosening abnormal sound.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the schematic diagram at another visual angle of the utility model.
Fig. 3 is the partial enlarged view of basic bottom.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
Multi-rotor unmanned aerial vehicle skeleton structure as depicted in figs. 1 and 2, it includes substrate 1, telescopic rod 2.
The substrate 1 is surrounded by equally distributed support arm 101, and the telescopic rod 2 is located at 101 lower section of support arm；Branch
Two sides are respectively equipped with opposite L-type deck 102 below 101 end of arm, and the telescopic rod 2 is sliding in corresponding L-type deck 102
It is dynamic；1 bottom of substrate is equipped with the limiting device 3 that 2 tail portion of telescopic rod is fixed；The end of the telescopic rod 2 is equipped with
Motor cabinet 201；Through-hole is provided on the substrate.
The limiting device 3 includes the vertical plate 301 and stop collar 302 of two loops；As shown in figure 3, two circle vertical plates 301
For concentric structure, there are gap between vertical plate 301, the height of the vertical plate 301 of inside is higher than the vertical plate 301 in outside；It stands inside
Plate 301 is higher than the part on the vertical plate 301 in outside and is equipped with external screw thread, and stop collar 302 is corresponding with the vertical plate 301 of inside, limit
Internal screw thread is equipped with inside the ring 302 of position, the form that stop collar 302 is threadedly coupled is mounted on the vertical plate 301 of inside；Described stretches
Perforative strip through-hole is equipped at 2 center of contracting bar；Position corresponding with the telescopic rod 2 of through-hole two sides on the vertical plate 301
Equipped with perforative through slot；The gap that the tail portion and middle part of the telescopic rod 2 are respectively equipped between through slot and vertical plate 301 is opposite
The limit plate 202 answered.
The front end of the support arm 101 is equipped with articulated section 103, and articulated section 103 is articulated with the end of support arm 101；The L-type
Deck 102 is located at the lower section of articulated section 103；103 front end of articulated section is equipped with arc groove corresponding with motor cabinet 201.
Gap between less than two vertical plates 301 of the end face width of the stop collar 302.
This skeleton is the infrastructure component that unmanned plane is built, and needs to install battery, control system in actual use above substrate
The components such as system will also install undercarriage in lower part, the operation such as motor is installed in motor cabinet.
The through-hole on through-hole and telescopic rod being arranged on substrate all largely alleviates the weight of skeleton.Pass through
Vertical plate limits telescopic rod, and telescopic rod slides in the L-type deck on support arm, also is provided with corresponding to telescopic rod on vertical plate
Through slot, the sliding of actually telescopic rod are carried out in through slot in L-type deck and on vertical plate, and two be arranged on telescopic rod
A limit plate can be installed between two vertical plates, vertical plate be buckled into the gap between vertical plate, and by stop collar screw-in
Telescopic rod is compressed on the vertical plate of side and realizes fixation.
When needing to stretch out, the limit plate of telescopic rod tail portion is buckled between vertical plate；When needing to retract, by telescopic rod front
Limit plate snaps between vertical plate.
Articulated section is set on support arm, and L-type deck is located at below articulated section, main purpose is that selection stretches out or contracts
Hui Shi can rotate telescopic rod, realize corresponding operation.Regardless of telescopic rod stretches out or retracts, main limit plate button
Enter the gap between vertical plate, and after screwing by stop collar, can guarantee the stability that telescopic rod connects on substrate.
The effect that the end face width of stop collar is less than the distance between vertical plate is to apply force directly to stop collar on telescopic rod,
Rather than be applied on the vertical plate in outside, only directly acting on telescopic rod just can be achieved really to compress and prevent to shake.
