The lateral movement to the left of push rod 22, and top pressure locking head 113 will be caused, make locking head 113 to left movement, while compress tapered end spring
114, tapered end spring 114 is put aside elastic force.The unblock button 24 is pressed until finally making the lower cooperation inclined-plane 1133 of locking head 113
Untill being removed completely from limiting section 25, now, that is, the latch functions of locking head 113 are relieved, locking head 113 can not limit again
Horn 2 processed turns clockwise.Now, the direction as shown in arrow R2 in Figure 14, the other hand apply pressure on horn lid 3,
Press down on horn lid 3；In this way, horn 2 is set to start to rotate in the direction of the clock.Limiting section 25 is gradually from the transfer of locking space
Go out, its process and the process that limiting section 25 is transferred in locking space are just the opposite.Meanwhile when limiting section 25 produces counterclockwise,
After push rod 22 will be separated gradually with locking head 113, and push rod 22 separates with locking head 113, locking head 113 is in compression spring 23
Under elastic force effect, apply active force to limiting section 25, further touching withdraws horn 2, now, without being unlocked by pressing button 24 again
(also it doesn't matter for pressing, will not be impacted to operation).
When the direction continu to press as shown in arrow R2 in figure, when horn 2 is retracted in certain angle, such as this example
Between horn 2 and body 1 angle be in 30 degree when, as shown in figure 15, now, its state refer to enlarged diagram shown in Figure 18 (because
State shown in Figure 15 is actual identical with state shown in Figure 12).Now, the limit bottom surface 251 of limiting section 25 exceedes locking head 113
Upper cooperation inclined-plane 1131, locking head 113 no longer to the application of limiting section 25 act on.
Finally, its result is as shown in figure 16, and its state refers to enlarged diagram shown in Figure 17 (because state shown in Figure 16 is real
Border is identical with state shown in Figure 17).The upper limit portion 25 of horn 2 and the locking head 113 on support base 11, lower lock section 110 etc. are not
Contact.Complete horn 2 and reclaim (or folding) action.
Unmanned plane provided by the invention, it passes through the lower lock section 110 being arranged on support base 11 and locking head 113 and horn
Limiting section 25 on 2 is engaged the expansion latch functions for completing horn 2, meanwhile, it can be by the push rod machine that is arranged on horn 2
Structure, the locking of locking head 113 is released, realize that the withdrawal of horn 2 folds.The fitting locking of its horn 2 is more firmly and smooth；And its
During releasing locking, it is necessary to which proficiency being unlocked by pressing button 24, the other hand apply pressure, could complete the realized depreciation of horn 2
Folded, in such cases, horn 2 will not voluntarily be fallen, and avoid horn 2 and voluntarily fall and hurt the situation of user, and horn 2 is being received
It is safer during inflection is folded.And the structure such as locking head 113 and transfer bar mechanism occupies little space, and effectively can save in unmanned plane
Portion space.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
