Specific embodiment
To facilitate the understanding of the present invention, the present invention is made below in conjunction with Figure of description and preferred embodiment more complete
Face meticulously describes, but the protection scope of the present invention is not limited to the following specific embodiments.
Such as Fig. 1-3, the folding paddle of the with locking mechanism, including paddle folder and blade 6, the paddle folder include upper paddle folder 4
Lower paddle folder 9 with the folder relative spacing setting of upper paddle, forms the connection for clamping blade between the upper paddle folder and lower paddle folder
The connecting pin of the grasping part at end, blade is rotatablely connected by rotary components and paddle folder, and the rotary components include that plug screws
1, axle sleeve 5 and jam nut 10, the connecting pin of blade offer rotational axis hole 62, the axle sleeve pass through rotational axis hole and with rotation
Axis hole is fixedly attached, and the plug, which screws, serves as the effect of rotary shaft body, and plug screws sequentially passes through paddle folder, axis from top to bottom
It is threadedly coupled after set and lower paddle folder with jam nut, plug screws to rotate with axle sleeve and be socketed, using this kind of connection type, in blade
Unlocked situation, applying certain external force can make blade relatively rotate with paddle folder.Between the upper paddle folder and lower paddle folder
By locking adjustment component connection at center, the locking adjustment component includes locking member 8 and adjustment disk 3, the locking member
Including integrally formed cap body and center axis body, the cap body side wall is circumferentially uniformly provided with a plurality of vertically extending positioning circular groove
81, offer on the lower paddle folder it is vertical extend and with the matched stepped hole of locking member, the front-rear side walls of lower paddle folder offer
The positioning screw hole being connected to stepped hole is threaded with the positioning bead that can be connect with positioning circular groove positioning card in each positioning screw hole
7, specifically, the positioning bead includes the head end of integrally formed truncated conelike and the tail end of cylindrical shape, head end and positioning
Circular groove positioning clamping, tail end are threadedly coupled with positioning screw hole；The central axis body side surface is the positioning cylindrical surface 82 of alternately connection
With notch plane 83, the connecting pin edge of blade has an arc groove 61 with positioning cylindrical surface clamping, center axis body from lower and
On sequentially pass through lower paddle folder and upper paddle folder after be socketed with adjustment disk, pass through fixed screw 2 between the adjustment disk and center axis body
Realization is connected and fixed, and specifically, the top center of center axis body offers threaded hole, fixed screw pass through after adjustment disk with spiral shell
Pit is threadedly coupled.
Specific use state is described in detail below: when the expansion of blade needs and needing with paddle clamp lock periodically, passes through adjusting
Disk drives locking member rotation, and arc groove is made to match clamping with positioning cylindrical surface, and makes positioning bead and positioning circular groove clamping, in this way
Ensure that propeller is accurately reliably locked in unfolded state, specific state diagram is as shown in Figure 4.When blade needs to fold
When, again by adjustment disk drive locking member rotation, when the positioning bead of positioning be detached from original circle of position slot be caught in again it is neighbouring
When positioning circular groove, at this time due to the notch plane contact of the connecting pin of blade and locking member, blade is not turned by positioning cylindrical surface
Dynamic limitation, then blade can rotate around the rotary centerline of its own and collapse blade.It is specific to collapse process and state such as
Shown in Fig. 5-6.
In conclusion the folding paddle of the structure, with overall structure is simple, installation process is easy and effectively increases paddle
The advantages of leaf and paddle clamp lock fixed reliability.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
