It is rectangular-ambulatory-plane to have the cuboid of through-hole, cross-sectional shape, on the basis of proof strength, reduces the weight of central balancing bar 34,
Horn is set to fold and be unfolded more convenient.
The first adjustable spring 100 is fixed in the present embodiment in first square hole 311, is consolidated in the second square hole 321
Surely there is the second adjustable spring 200；The free end of first adjustable spring 100 is fixed in first rotating shaft 342, the second adjustable spring
200 free end is fixed in the second shaft 343.It is for the ease of in specifically to make the folding of horn and being unfolded conveniently
Centre balancing pole 34, which is converted to the state out of the first square hole 311 and the second square hole 321, is fixed on the first supporting table
20 and second supporting table 40 state.One end of first adjustable spring 100 and the second adjustable spring 200 is being individually fixed in first just
The bottom of square hole 311 and the second square hole 321, it is preferred that fixed by the way of welding, the other end is separately fixed at the
In one shaft 342 and the second shaft 343, thus by the first adjustable spring 100 and the second adjustable spring 200 and central balancing bar 34
Connection.When horn is unfolded, that is, central balancing bar 34 is in the first square hole 311 and the second square hole 321
When state, screw thread shell 33 fixes the first connector 31 and the second connector 32 in outside, the first adjustable spring 100 and second
Adjustable spring 200 is in compressive state.When horn becomes folded state from unfolded state, screw thread shell 33 turns to the first company
On fitting 31 or the second connector 32, the first adjustable spring 100 and the rebound of the second adjustable spring 200, central balancing bar 34 will be from
Pop-up in first square hole 311 and the second square hole 321, then the first connector 31 and the second connector 32 are rotated 90 °,
Central balancing bar 34 is fixed in the first supporting table 20 and the second supporting table 40, the first adjustable spring 100 and the second adjustable spring
200 are in tensional state.When being converted to unfolded state by folded state, the pulling force of spring pulls central balancing bar 34 to first
Square hole 311 and the sliding of the second square hole 321, the conversion of horn two states have been utilized respectively the first adjustable spring 100
With the screen resilience and pulling force of the second adjustable spring 200, the consumption of power in expansion and folding process is reduced with this so that horn folds
It is simple laborsaving with expansion switching, it is easy to use.
The width of the first guide groove 10 and the second guide groove 30 is more than first rotating shaft 342 and the second shaft 343 in the present embodiment
Diameter, first rotating shaft 342 and the second shaft 343 are led in the first guide groove 10 and second respectively when being folded or be unfolded convenient for horn with this
Slot 30 slides.
The width of the first square hole 311 and the second square hole 321 is more than the width of central balancing bar 34 in the present embodiment
Degree；The sum of length of first square hole 311 and the second square hole 321 is more than the length of central balancing bar 34, is convenient for this
The movement in the first square hole 311 and the second square hole 321 of central balancing bar 34, is in horn when horn transition status
When unfolded state, central balancing bar 34 is completely accommodated in the first square hole 311 and the second square hole 321, makes horn
Length will not be elongated because of folding device.
The width of the first supporting table 20 and the second supporting table 40 is equal to the width of central balancing bar 34 in the present embodiment, two
When a horn is in folded state, central balancing bar 34 is fixed in the first supporting table 20 and the second supporting table 40, to make folding
It is in stable condition reliable, therefore the width of the first supporting table 20 and the second supporting table 40 is made to be equal to or slightly less than central balancing bar 34
Width, can avoid central balancing bar 34 in this way and the connection of the first connector 31 and the second connector 32 loosens.
The multi-rotor unmanned aerial vehicle horn folding device of the utility model is during expansion, first the first connector and second
Connector is rotated around central balancing bar, is rotated as the first connector and two axis axle center of the second connector on a horizontal line；
Central balancing bar is connected to the first connector and second respectively under the pulling force effect of the first adjustable spring and the second adjustable spring
Part internal slide finally fits together the end face of the first connector and the second connector, by rotating screw thread shell the
A connection piece and the second connector are connected through a screw thread, and are played the role of fixed.The process of folding with the above process on the contrary,
Screw thread shell turns on the first connector or the second connector, and the first adjustable spring and the rebound of the second adjustable spring, center are flat
Weighing apparatus bar is popped up out of the first connector and the second connector, then the first connector and the second connector are rotated 90 °, central balancing
Bar is fixed on the first connector and the second connector, that is, is completed horn and folded.
Using the multi-rotor unmanned aerial vehicle horn folding device of the utility model, by the way that connection is respectively set on two horns
Part makes horn fold and be unfolded, is consolidated after deployment by screw thread shell by central balancing bar and connector rotation connection
Calmly, when folding screen resilience is provided by the spring set in connector.Entire folding devices fold and expansion easy switching, structure letter
It is single, it is reliable and stable, it is easy to use.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
It, in specific embodiments and applications can be with many changes may be made, as long as these variations are without departing from this with novel thought
The design of utility model, belongs to the scope of protection of the utility model.
