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 compatible not high problem, and the unmanned plane horn
It is more convenient to use with shaft.
In order to solve the above technical problems, the utility model adopts the following technical solution:
A kind of unmanned plane horn shaft, which is characterized in that the unmanned plane horn shaft include: central spindle, external cam,
Cam ring, spring and circlip；Described central spindle one end has step, and the other end passes through the external cam, cam ring and spring
Afterwards, it is connected and fixed with the circlip, the spring is compressed and made external cam, cam ring positive engagement；And the external cam
Relative rotation angle between cam ring is divided into three sections, respectively close segments, free segment and opening section；Make when applying external force
Relative angle between the two is located in close segments, and unmanned plane horn can be closed automatically with shaft after removing external force；It is outer when applying
Power is located at relative angle between the two in opening section, and unmanned plane horn shaft can automatically open after removing external force；It applies
Add external force that relative angle between the two is located in free segment, unmanned plane horn shaft can maintain after removing external force.
In preferred technical solution, the corresponding angle of the close segments is 0 °~80 °, and the corresponding angle of free segment is 80 °
~100 °, opening the corresponding angle of section is 100 °~180 °.
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 be located at circlip and spring it
Between, thus inside the shell by spring and cam ring closing.
In further preferred technical solution, positioning protrusion, the circlip position are additionally provided on the outside of the bucket bottom of the shell
In in the positioning protrusion.
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 the three-stage design of its rotational angle, so that using more
Add conveniently, consumer experience is more preferable.
The utility model is described in further detail with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is a kind of schematic perspective view of unmanned plane horn shaft of specific embodiment of the present invention；
Fig. 2 is a kind of cutting structural schematic diagram of unmanned plane horn shaft of specific embodiment of the present invention；
Fig. 3 is a kind of exploded view of unmanned plane horn shaft of specific embodiment of the present invention.
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 circlip 6；Described 4 one end of central spindle has step 41, and the other end is suitable
After sequence passes through the external cam 1, cam ring 2 and spring 5, connected and fixed with the circlip 6, the spring 5 is compressed and made
External cam 1,2 positive engagement of cam ring；And the relative rotation angle between the external cam 1 and cam ring 2 is divided into three sections, respectively
For close segments, free segment and open section；When applying external force relative angle between the two is located in close segments, removes external force
Unmanned plane horn can be closed automatically with shaft afterwards；When applying external force relative angle between the two is located in opening section, removes
Except unmanned plane horn shaft can automatically open after external force；Applying external force makes relative angle between the two be located at free segment
Interior, unmanned plane horn shaft can maintain after removing external force.It should be noted that joining for different materials and spring
