Specific embodiment
It is not to this hair it should be noted that " up and down " being described according to shown in attached drawing in the present embodiment
Bright limitation.It can be set according to specific requirement into row position.
1-6 is further described the present invention below in conjunction with the accompanying drawings：As shown in Figs. 1-3, a kind of slide locking buckle device, peace
Loaded in 3 structure of fuselage skin, for limiting the rotation of foot pedal 2, control its folding, the locker include nut 11,
Lock 12, lock 13, bolt 14, special bolt 15, spring 16；Wherein, special bolt 15 is T-shaped, including with outside lock
The parallel bolt head 151 in surface and the body being vertically arranged, body are provided with screw thread 152 close to one end of bolt head 151, remaining
Part is polished rod 153, and 152 position diameter of screw thread is more than 153 position diameter of polished rod, and the body is disposed through 12 top of lock
Through hole；The nut 11 is matched with the screw thread 152 of special bolt, for special bolt 15 to be fixed on lock 12；It is described
Lock 13 includes accommodating the lock perforate 131 passed through of polished rod 153 and the lock extending area 133 engaged with foot pedal card slot 22,
The lock 13 is moved up and down along polished rod 153；The spring 16 is placed on polished rod 153, and against nut 11, the other end supports its one end
By lock 13；There are the cotter-pin hold 154 for preventing that lock from dislocating, 14 insertion opening pin hole 154 of bolt in the end set of polished rod 153
For preventing 13 dislocation of lock.
