Working principle:

Under the normal working state, the inertial lock 2 is in an initial position under the action of the torsion spring 3, the clamping block 21 of the inertial lock 2 is blocked by the limiting plate 11, and at the moment, the unlocking swing arm 4 can freely rotate and cannot be blocked by the inertial lock 2; when the collision is generated, the inertial lock 2 rotates under the action of inertial force, when the clamping block 21 rotates to exceed the limiting plate 11, under the pushing of the torsion spring 3, the clamping block 21 is clamped into the clamping groove 111, the inertial lock 2 cannot return in advance at the moment, when the unlocking swing arm 4 rotates to reach the position of the inertial lock 2, the unlocking swing arm 4 is shielded by the inertial lock 2 at the moment, and at the moment, the two conditions are as follows:

(1) If the inertia force of the unlocking swing arm 4 is insufficient to enable the clamping block 21 of the inertial lock 2 to be separated from the clamping groove 111, at the moment, the swing arm 3 is reset under the action of the elastic reset mechanism under the action of collision fluctuation elimination, the handle main body 5 is pressed by a human hand to drive the unlocking swing arm 4 to act, the unlocking swing arm 4 overcomes the thrust of the torsion spring 3 and pushes the inertial lock 2 to slide first, when the clamping block 21 is separated from the clamping groove 111, the inertial lock 2 returns under the torsion force of the torsion spring 3, the clamping block 21 is blocked by the limiting plate 11, the human hand leaves the handle main body 5, and the swing arm 3 is reset under the action of the elastic reset mechanism;

(2) If the inertial force of the unlocking swing arm 4 is large enough to disengage the latch block 21 of the inertial lock 2 from the latch groove 111, but since the pawl 22 is blocked by the flange 41, the inertial lock 3 cannot be quickly returned until the energy fluctuation of the collision is eliminated, and the inertial lock 3 cannot be returned until the energy fluctuation of the collision is eliminated, so that the unlocking swing arm 4 is prevented from rotating in the unlocking direction after the inertial lock 3 is driven to return, the energy fluctuation of the collision is generally uncertain within 35ms, but the handle cannot be unlocked only between energy reductions. In this case, the handle body 3 is also pressed after the collision, but only then the inertial lock 2 has been returned, and the unlocking swing arm 4 idles and then returns.

The inertial lock structure can be applied to all handles, such as rotary handles, flat handles, push-button handles, fixed handles, conventional handles, and the like.

The present utility model is not limited to the above-mentioned embodiments, and any person skilled in the art, based on the technical solution of the present utility model and the inventive concept thereof, can be replaced or changed within the scope of the present utility model.
