[0002] Small aircraft generally refer to light aircraft suitable for transporting a small number of passengers or cargo, and are usually used for private flights, training, short trips, medical rescue and other purposes. According to the size and purpose, small aircraft can be divided into the following types: trainer aircraft and sports aircraft. The slide rail system of small aircraft seats is a very important part of aircraft seat design, mainly used to ensure that the seats can move forward and backward in the cabin. The seat system allows passengers to adjust the seat position according to personal needs, and at the same time facilitates the crew to quickly evacuate passengers in an emergency. The seat slide rails are generally made of metal materials, which are characterized by high strength and wear resistance. Aircraft seat slide rail installation inspection is an important part of ensuring the safety and reliability of aviation seats.

The internal dimensions of the hole groove 4 (805) are adapted to the external dimensions of the sliding rod (1506) in turn.

8. The small aircraft seat rail installation detection device according to claim 1, characterized in that: Two connectors (906) are symmetrically plugged into the side wall of the stress sensor (902), and the connectors (906) are coupled to the display screen (13) and the alarm light (14) in turn through wires and PLC.

9. A small aircraft seat rail installation and detection device, using the small aircraft seat rail installation and detection device as described in any one of claims 1 to 8, characterized in that: The following steps are involved: S1: Installation and positioning, the base (301) is sleeved on the outer surface of the positioning block (7), the two claws (801) are sequentially inserted into the convex slider (802), the servo motor (4) is started to drive the bidirectional screw (6) to rotate clockwise, so that the convex slider (802) and the screw slide (803) cooperate to drive the claws (801) to move toward each other, thereby clamping the base (301), thereby limiting the horizontal lateral movement of the base (301), and then turning the knob clockwise ( 1505) can adjust the height of the support plate (1503), thereby reducing the distance between the base (301) and the vertical plate (2). The operator then starts the cylinder two (11) and the cylinder one (901) to adjust the positional relationship between the connecting block (903) and the connecting seat (305), so that the two hole grooves five (905) are concentric with a group of hole grooves one (306), and then the two slots two (5) are inserted into the hole grooves five (905) and threadedly connected to the inside of the hole groove one (306). S2: Sliding side view, the operator starts the cylinder 1 (901) to drive the stress sensor (902) and the connecting block (903) to move horizontally back and forth, thereby driving the slider frame (304) and the connecting seat (305) to move horizontally synchronously. The operator observes the sliding state of the slider frame (304) inside the track groove (307). The stress sensor (902) can display the tension and pressure measured when the hole groove 5 (905) moves on the surface of the L-shaped bracket (12) after PLC logic processing. S3: For replacement and disassembly, the operator first rotates the two limit screws (904) to release the limit on the connecting block (903) and the connecting seat (305), then rotates the two knobs (1505) counterclockwise, and then reversely drives the servo motor (4) to drive the bidirectional screw (6) to rotate counterclockwise, so that the two claws (801) gather in the middle, thereby releasing the limit of the claws (801) on the base (301), so as to facilitate the removal and replacement of the base (301).
