Detailed ways

The following are specific embodiments of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.

As shown in Figures 1 and 2, the utility model provides an electronic lock with an emergency unlocking structure, which includes a lock body 1, a signal acquisition device, a handle 2, a handle shaft 3, a main lock cylinder assembly and a clutch shaft 4.

There is a torsion spring 5 between the handle shaft 3 and the lock body 1 of the electronic lock. The clutch shaft 4 is connected to the main lock cylinder assembly through a square pin 6. One end of the handle shaft 3 is connected to the handle 2, and the other end passes through the clutch. The rotating shaft 4, the handle shaft 3 and the clutch rotating shaft 4 are coaxial and can rotate relatively freely. A clutch mechanism is arranged between the handle shaft 3 and the clutch rotating shaft 4, and the signal acquisition device controls the action of the clutch mechanism. The clutch mechanism includes a driver 7, a push pin 8 and an arc-shaped pressing plate 9. The side wall of the handle shaft 3 is provided with a pin hole 10, the push pin 8 is arranged in the pin hole 10 and can move back and forth along the pin hole 10, a limit copper sleeve 11 is arranged in the pin hole 10, and the outer wall of the clutch shaft 4 is provided with a limit Hole 12, the outer end of the push pin 8 protrudes from the copper sleeve 11 and leans against the concave surface of the pressure plate 9, the inner end can be inserted into the above-mentioned limiting hole 12, and a return spring is also provided between the push pin 8 and the handle shaft 3 13.
