The automatic interlocking locking device according to claim 4, wherein the interlocking mechanism (23) comprises a second guide structure (231) arranged between the first runner assembly (210) and the second runner assembly (241), a second locking piece (232) movably arranged on the second guide structure (231), and a second reset mechanism arranged between the second guide structure (231) and the second locking piece (232), the first runner assembly (210) rotates to drive the wedge-shaped groove (2101) to overcome the pre-pressing elastic force of the second reset mechanism and push a second locking piece (232) in the wedge-shaped groove (2101) to be inserted into a clamping groove (2401) on the second runner assembly (241) so as to lock the second runner assembly (241), the first runner assembly (210) drives the wedge-shaped groove (2101) to rotate, and the wedge-shaped groove (2101) and the second locking piece (232) are opposite to force the pre-pressing elastic force of the second locking piece (2101) to be inserted into the clamping groove (2401) through the first reset mechanism (223).
6. The automatic interlocking locking device according to claim 5, wherein one end of the first locking member (222) and one end of the second locking member (232) for abutting against the wedge-shaped groove (2101) are both provided as an arc surface or a spherical surface.
7. The automatic interlocking locking device according to claim 1 or 5, wherein an electric appliance body is mounted on the moving part (1), a moving contact is connected to the electric appliance body, a fixed contact is connected to the fixed part (2), the moving part (1) drives the moving contact to be conducted with the fixed contact to realize power supply, and the moving part (1) drives the moving contact to be separated from the fixed contact to realize power supply.
8. An automatic interlocking locking device according to claim 2 or 5, characterized in that a connection is provided between the moving part (1) and the fixed part (2), the connection being driven by the movement of the moving part (1) to power the rotation of the drive assembly (21).
9. The automatic interlocking locking device according to claim 8, wherein the connecting structure comprises a pushing member (12) connected to the moving part (1) and a third reset mechanism (26) arranged on the fixed part (2), the moving part (1) drives the pushing member (12) to move so as to push the power arm (211) to drive the first rotating wheel assembly (210) to rotate against the pre-pressing elastic force of the third reset mechanism (26), and the moving part (1) drives the pushing member (12) to move away from the power arm (211) so that the pre-pressing elastic force applied by the third reset mechanism (26) forces the power arm (211) to drive the first rotating wheel assembly (210) to rotate and reset.
10. A quick opening door comprising an automatic interlocking latch as claimed in any one of claims 1 to 9.
