Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

The multi-functional double-layer compound cabin door with self-locking and anti-locking device of the present invention comprises a hinge and pin shaft assembly 1, an outer door assembly 2, an inner door assembly 3, an inner turntable 4, an outer turntable 5, and a left latch moving part assembly 6. The right bolt moving part assembly 7, the gear transmission assembly 8, the door frame assembly 9, the self-locking device assembly 10, the anti-locking device assembly 11, etc., the inner turntable 4 and the outer turntable 5 move the left door bolt mover assembly through the gear transmission assembly 8 6 and the right bolt mover assembly 7, the bracket platform 10.3 in the self-locking device assembly 10 is fixed between the inner and outer door assemblies, supporting the first guide rod 10.2, and the first guide rod 10.2 passes through the left bolt mover assembly 6 , the two ends are respectively connected to the self-locking button 10.1 and the locking piece 10.5, the locking piece 10.5 is connected and installed between the inner and outer door components through the first pin 10.9, and connected to the bracket platform 10.3 through the spring 10.4, the anti-locking device component 11 The rotating shaft 11.2 in the middle is installed on the fixed block 12 on the inner door panel, and the two ends are respectively connected with the rotating plate 11.1 and the rotating handle 11.3, and the top of the rotating plate both sides is equipped with a block 11.4 and a bolt 11.5.

The two ends of the second guide rod 10.6 in the self-locking device assembly 10 are respectively connected with a locking button 10.7 and a locking block 10.8, and the locking block 10.8 is connected and fixed on the plate of the gear transmission assembly 8 through the second pin 10.10 .

The locking piece 10.5 in the self-locking device assembly 10 is in the shape of a hook.
