Referring to fig. 1 to 3, the present embodiment provides a quick locking mechanism for connecting an interfering object transmitting box 1 of a helicopter with a firing control seat 2 of the helicopter.
The quick lock mechanism includes a lock lever 31, a connecting cylinder 32, and a plunger 33.
The left end of the locking rod 31 is provided with a threaded part 311, and the right end is fixedly connected with the connecting cylinder 32; the screw part 311 is provided with external screw threads, the firing control seat 2 is provided with a positioning boss 21 which is used for being inserted into the interfering object transmitting box 1, and the positioning boss 21 is provided with internal screw threads which are matched with the external screw threads. The positioning boss 21 is used for positioning before installation; in other embodiments, the positioning boss 21 may be disposed on the jammer transmitting box 1, or neither the firing control seat 2 nor the jammer transmitting box 1 may be disposed with the positioning boss 21.
The connecting cylinder 32 is inserted into the inserting rod 33.
The cross section of the inserted link 33 is polygonal, the inserted link 33 is detachably connected with the interfering substance emitting box 1, and after the inserted link 33 is connected with the interfering substance emitting box 1, the interfering substance emitting box 1 can restrict the rotation of the inserted link 33. In this embodiment, the cross section of the insert 33 is regular hexagonal.
When the quick lock mechanism is used, the quick lock mechanism can be firstly arranged on the interfering object transmitting box 1, when the quick lock mechanism is arranged on the interfering object transmitting box 1, the inserted link 33 can be firstly connected with the right end face of the interfering object transmitting box 1, and then the connecting cylinder 32 on the locking rod 31 is spliced with the left end of the inserted link 33. In actual use, the quick lock mechanism is mounted on the interfering object transmitting box 1 in advance, that is, before the interfering object transmitting box 1 is connected with the firing control seat 2, the quick lock mechanism and the interfering object transmitting box 1 are assembled.
When the interfering object transmitting box 1 is connected with the firing control seat 2, the positioning boss 21 on the firing control seat 2 can be inserted with the corresponding part of the interfering object transmitting box 1, and then the threaded part 311 of the locking rod 31 can be screwed into the positioning boss 21.
When the interfering object transmitting box 1 and the percussion control seat 2 need to be separated, the inserted link 33 is separated from the right end face of the interfering object transmitting box 1, and the locking link 31 can be screwed to separate the threaded portion 311 and the positioning boss 21.
