It folds or is unfolded.
The unmanned plane for having used the folding horn turning gear can pack up horn when carrying, and portability improves, but
Be the folding horn turning gear include horn itself, thus the horn of various specifications cannot be applicable in, be unfavorable for modularization and
Compatibility uses and shows slightly inconvenient；And we have found that horn is easy to happen jump when unmanned plane is overturn in flight course
Dynamic, tracing it to its cause may be related with horn shaft, it is therefore desirable to improve.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of unmanned plane horn shafts, and there are currently no special for solution
The unmanned plane horn shaft of door, is unfavorable for unmanned plane modularization and compatibility is not high, and horn holds during wing-over
The problem of easily beating.
In order to solve the above technical problems, the utility model adopts the following technical solution:
Unmanned plane horn shaft, comprising: central spindle, external cam, cam ring, spring and L shape fixinig plate；Described central spindle one end
With step, after the other end passes through the external cam, cam ring and spring, connected and fixed with the L shape fixinig plate, it is described
Spring is compressed and is made external cam, cam ring positive engagement.
In preferred technical solution, the relative rotation angle between the external cam and cam ring is divided into three sections, respectively
Close segments, free segment and opening section；When applying external force relative angle between the two is located in close segments, after removing external force
Unmanned plane horn can be closed automatically with shaft；When applying external force relative angle between the two is located in opening section, removes
Unmanned plane horn shaft can automatically open after external force；Applying external force is located at relative angle between the two in free segment,
Unmanned plane horn shaft can maintain after removing external force.
In further preferred technical solution, the corresponding angle of the close segments is 0 °~80 °, the corresponding angle of free segment
It is 80 °~100 °, opening the corresponding angle of section is 100 °~180 °.
In preferred technical solution, the L shape fixinig plate is equipped with mounting hole.
In preferred technical solution, the unmanned plane horn shaft further includes shell, and the shell is in barrel-shaped, opening
One end filled in and closed by external cam, the bucket bottom of the other end is threaded through in the central spindle, and bucket bottom is located at L shape fixinig plate and bullet
Between spring, thus inside the shell by spring and cam ring closing.
The beneficial effects of the utility model are:
Using a kind of unmanned plane horn shaft of technical solutions of the utility model, it can be used as standard component and be applied to
The unmanned plane horn of plurality of specifications and being rotatably connected for fuselage, and it increases the design method of L-type fixinig plate in tail portion, it can
To effectively reduce or overcome the problems, such as that unmanned plane horn during wing-over is beated.
The utility model is described in further detail with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the schematic perspective view of specific embodiment of the present invention unmanned plane horn shaft；
Fig. 2 is the cutting structural schematic diagram of specific embodiment of the present invention unmanned plane horn shaft；
Fig. 3 is the exploded view of specific embodiment of the present invention unmanned plane horn shaft.
Specific embodiment
A kind of unmanned plane horn shaft that present embodiment provides is as shown in Figures 1 to 3, and the unmanned plane horn is used
Shaft includes: central spindle 4, external cam 1, cam ring 2, spring 5 and L shape fixinig plate 6；Described 4 one end of central spindle has step 41, another
After end passes through the external cam 1, cam ring 2 and spring 5, connected and fixed with the L shape fixinig plate 6, the spring 5 is pressed
It contracts so that external cam 1,2 positive engagement of cam ring.
Using a kind of unmanned plane horn shaft of specific embodiment of the present invention technical solution, can be used as
Standard component is applied to the unmanned plane horn of plurality of specifications and being rotatably connected for fuselage, and it increases L-type fixinig plate 6 in tail portion
Design method, can effectively reduce or overcome the problems, such as that unmanned plane horn during wing-over is beated.
Relative rotation angle between the external cam 1 and cam ring 2 is divided into three sections, respectively close segments, free segment and
Open section；When applying external force relative angle between the two is located in close segments, unmanned plane horn use turns after removing external force
Axis can be closed automatically；When applying external force relative angle between the two is located in opening section, removes unmanned plane machine after external force
