The ejection hanging point 7 answered is fixed.With ejection tool, there are four the unmanned plane of fixed-wing, (four fixed-wings are relative to the unmanned plane plane of symmetry two
To symmetrical, when unmanned plane is connect with the present invention, the unmanned plane plane of symmetry is overlapped with 1 plane of symmetry of track) for, as n=2, m=1,
Four unmanned plane hooks 6 (can not have with corresponding ejection hanging point 7 with a pair of of fixed-wing of fixed symmetrical there are two in four fixed-wings
There is unmanned plane to link up with 6, there are two unmanned planes to link up with 6 on other two fixed-wing, and two unmanned planes on a fixed-wing are hung
There are one being fixed between ejection hanging point 7 and baffle 4-2 in hook 6, another only connects ejection hanging point 7 only by ejection hanging point 7
Fixation) or four unmanned planes hook 6 can fix a fixed-wing respectively (in four fixed-wings with corresponding ejection hanging point 7
Any pair of symmetrical fixed-wing on unmanned plane hook 6 be fixed on ejection hanging point 7 and baffle 4-2 between, another pair is symmetrical
Fixed-wing on unmanned plane hook 6 only connection ejection hanging points 7 only by ejection hanging point 7 fixation)；If n=m=2, each
Unmanned plane hook 6 is all fixed by launching hanging point 7 and baffle 4-2.As n=m=1, then any pair in four fixed-wings
A unmanned plane hook 6 is separately connected on symmetrical fixed-wing, and unmanned plane hook 6 is fixed on ejection hanging point 7 and baffle 4-2
Between.By taking unmanned plane of the ejection tool there are two fixed-wing as an example, if n=m=2, two unmanned planes are installed on each fixed-wing
Hook 6, and each unmanned plane hook 6 is fixed between ejection hanging point 7 and baffle 4-2.
Baffle 4-2, baffle supporting device and brake cable 10 collectively form blocking device, as shown in Figure 1, nothing in present embodiment
The quantity of man-machine hook 6, ejection hanging point 7 and blocking device selects 2, and blocking device is known as according to the position relationship that mirror image is arranged
Right blocking device 4 and left blocking device 5, right blocking device 4 are identical with the structure of left blocking device 5.Control in present embodiment
Device 3 processed is identical as the quantity of brake cable 10, is also two, and control device 3 connects one to one with brake cable 10, two control devices
3 and brake cable 10 control right blocking device 4 and left blocking device 5 respectively.Plane of symmetry mirror of two control devices 3 relative to track 1
As symmetrical.
The present invention coordinates ejector, is mounted on ejector, is suitble to various ejectors.The coaster 2 of ejector is installed in-orbit
On road 1, bracket 9 is fixed on coaster 2, and supporting plate 8 is mounted on bracket 9.6 connection unmanned plane fixed-wing of unmanned plane hook, baffle
4-2 and ejection hanging point 7 coordinate fixed unmanned plane hook 6, ensure that unmanned plane formerly starts produced by motor or engine just
Unmanned plane position is motionless under the action of beginning motive force, is as latched.Under blocking when preparing ejection, unmanned plane hook 6 is
Stretching hook on unmanned plane, is the main function point during catapult-assisted take-off.Unmanned plane hook 6 and ejection hanging point 7
It completely attaches to, it is ensured that being launched between hanging point 7 and unmanned plane hook 6 in ejection instantaneous does not have impact force.When preparing to launch
Under blocking, baffle 4-2 is completely attached to unmanned plane hook 6, it is ensured that after unmanned plane motor or engine start, nothing
It is man-machine will not due to airscrew thrust and forward play, to avoid unmanned plane hook 6 from being detached with ejection hanging point 7, and then guarantee
Being launched between hanging point 7 and unmanned plane hook 6 in ejection instantaneous does not have impact force.Release movement is synchronized along with projectile motion and is sent out
Raw, i.e., the coaster 2 of ejector starts release function relative in the movement of track 1, is controlled by control device 3 and pulls brake cable
10, and then baffle supporting device discharges baffle 4-2, discharges unmanned plane, unmanned plane hook 6 is mounted in the stretching on unmanned plane and hangs
Hook discharges unmanned plane wing immediately when the no longer fixed unmanned planes of baffle 4-2 link up with 6, and the process of the catapult-assisted take-off of this mechanism is closed
Reason is reliable, and uses full mechanical, without artificial interference, can guarantee that operating personnel are safe, reusable.Two symmetrical peaces
Unmanned plane hook 6, ejection hanging point 7 and the baffle 4-2 of dress, can realize above-mentioned effect and effect.If n=m>1 or n>When m, one
Unmanned plane fixed-wing is fixed to symmetrically launching hanging point 7, unmanned plane hook 6 and baffle 4-2；Others ejection hanging point 7, unmanned plane
Link up with 6 and baffle 4-2 (n=m>1), or others launch hanging point 7 and unmanned plane links up with 6 (n>M), further fixed nothing is realized
It is man-machine, further prevent unmanned plane from verting.

Step 2：Rocking bar 4-3 is rotated into (to horizontality) manually, prepares locking.
Step 3：Lower handle 4-10, manual handle 4-10 and bolt axle 4- are pressed along the guiding slot port 4-9-1 for being oriented to card slot 4-9
6 pop up in bolt box 4-7 under the action of spring 4-8 and contact supporting crank 4-3.
Step 4：Adjusting knob 4-5, regulating fender 4-2 and unmanned plane hook 6 to the state of full contact are rotated, locking is completed
(unmanned plane hook 6 is secured in horizontal direction), the effect of blocking is as shown in Figures 1 to 4.
A kind of unmanned aerial vehicle ejecting locking provided by the invention and the release course of work of relieving mechanism are：
When ejector works, the direction shown in C along Figure 10 of coaster 2 moves, that is, travels forward, the ends rocking arm 3-1 and block
3-6 is contacted.Block 3-6 hinders the lower end of rocking arm 3-1 and block 3-6, causes the directions shown in D along Figure 10 rocking arm 3-1 to rotate, shakes
The upper ends arm 3-1 pull brake cable 10, and by the gearing of brake cable 10, the direction shown in A along Fig. 3 of brake cable 10 moves (downward), band
Dynamic bolt axle 4-6 detaches the i.e. bolt axle 4-6 that retracts from bolt box 4-7 and moves downward.Rocking bar 4-3 loses the branch of bolt axle 4-6
Support, together with baffle 4-2,4-4 rotates the direction of motion as shown in B in Fig. 3 around the shaft under the effect of gravity, to complete to unmanned plane
The release of hook 6, unmanned plane hook 6 are detached from the fixation of baffle 4-2.Handle 4-10 is moved along the notch for being oriented to card slot 4-9, finally
Under the action of spring 4-8, handle 4-10 is fixed on self-locking at the E as shown in Fig. 5~Fig. 8 of guiding slot port 4-9-1.After release
The effect of release conditions is as shown in Figure 9.Under release conditions, all unmanned planes hook 6 only by ejection hanging point 7 fixation (i.e.
The only connection unmanned plane fixed-wing of unmanned plane hook 6 and ejection hanging point 7).
Under the ejection force effect of ejector, unmanned plane travels forward in (directions C), and unmanned plane hook 6 is moved to the directions C,
Until being detached from the cooperation with ejection hanging point 7, unmanned plane launches away under the action of ejector.
A kind of unmanned aerial vehicle ejecting locking provided by the invention and relieving mechanism, are particularly suitable for catapult-assisted take-off side after first starting
The fixed-wing unmanned plane of formula, applies also for the unmanned plane of any type catapult-assisted take-off.
