Distinctive features of the proposed device are:

- the upper and lower flat contact surfaces of the slider can be located at an angle to each other, while the lower flat contact surface is located at an obtuse angle to the normal surface of the aircraft and coincides with the gripper guides in the docked position of the mechanical lock and the slider.

Due to the presence of a distinctive feature in combination with known ones, quick docking and undocking of the load-bearing connection is ensured without special tools.

The invention can find application on aircraft that require rapid installation and dismantling of the payload.

The technical solution is illustrated by the design of the lock for securing the payload of an unmanned aerial vehicle, shown in the drawings, Figs. 1...5.

In fig. 1 shows a longitudinal section of the fastening lock in a docked, fixed state with the slider;

In fig. 2, shows a longitudinal section of the fastening lock in the mounting / dismantling state with the slider;

In fig. 3 shows section A-A of FIG. 1, explaining the design of the fastening lock in the docked, fixed state with the slider;

In fig. 4 shows a longitudinal section of the fastening lock with gripping guides located at an obtuse angle to the normal of the aircraft surface and the lower flat contact surface of the slider in a docked, fixed state with the slider;

In fig. Figure 5 shows an isometric view explaining the design of the slider.

The lock for fastening the payload of an unmanned aerial vehicle includes a mechanical lock 1 consisting of a lock body 2 with a cavity 3 and a lock body cover 4, located in the volume of the aircraft and fixed on its surface 5, gripping guides 6 placed on the surface of the aircraft, a gripping device 7 installed in the cavity of the lock body to ensure interaction with the gripping guides and the slider 8. The gripping device is made in the form of a rod 9 pressed by a compression spring 10 installed with emphasis on the lock body cover and equipped with a pin 12 on the outer end surface 11 and placed with displacement from it by release button 13 with a length equal to the length of the pin. The cover is fixed to the lock body through the threaded surface 14. The slider is a payload fastening power element, made in the form of a central body 15 with a contact element 16 in the form of a transverse ledge located perpendicularly and symmetrically at the end of the central body of the slider across the location of the grip guides and with a length equal to the width their girth, with the upper and lower flat contact surfaces, 17 and 18, respectively, located parallel, and coinciding with the surface of the aircraft and the grip guides, respectively, in the docked position of the mechanical lock and the slider, a fixation hole 19 is made on the upper flat contact surface 17 of the slider the slider is concentric with the location of the gripper device pin in the docked position with the mechanical lock; in the front upper corner of the slider contact element there is a bevel 20 with the height of the larger protruding part of the gripper device pin in the lowest position of the gripper device and an angle that allows the gripper device to be pressed when installing the slider. The gripper guides are made in the form of two symmetrical guides, located offset from the surface of the aircraft, with a length equal to the cross section of the contact element of the slider, while the distance between the guide grippers is equal to the thickness of the central body of the slider. The gripper guides and the lower flat contact surface 18 of the slider can be located at an obtuse angle to the normal of the aircraft surface. In this case, the length and diameter of the protruding part of the pin, the length of movement of the gripping device rod are selected from the condition of reliable fixation and release of the payload mounting slide.

The drone payload lock works as follows:

To dock the payload with the supporting structure, the payload is supplied to the supporting structure, and sliding the upper and lower flat contact surfaces of the slider, respectively, along the gripping guides and the surface of the aircraft, contacting the bevel of the contact element of the slider with the pin of the gripping device with compression of the compression spring, the gripping device is recessed inside of the lock body until the end surface of the pin coincides with the surface of the aircraft; with further movement of the slider, the end surface of the pin comes into contact with the upper flat contact surface of the slider, sliding along it until the concentric position of the pin of the gripper device with the hole for fixing the slider, after which, under the action of a compression spring, the gripper device moves to the lowest position until the outer end surface stops at the bottom 21 of the lock body, inserting the pin into the slider fixation hole, fixing the docked position of the payload slider and the mechanical lock of the supporting structure (Fig. 1, 2, 3, 4, 5). To undock the payload from the supporting structure, it is necessary to press the release button, manually compressing the compression spring until the end surface of the release button coincides with the surface of the aircraft, after which, sliding the upper and lower flat contact surfaces of the slide along the gripping guides and the surface of the aircraft, the payload the load is removed from the supporting structure until it is completely separated, and the release button is released and, under the action of the tension spring, the gripping device moves to the lowest position until the outer end surface rests on the bottom of the housing (Fig. 1, 2, 3, 4, 5).
