The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] like Figures 1 to 4 As shown, an automatic locking mechanism for an unmanned forklift comprises an unmanned forklift body 1 and a support seat 5 fixedly mounted on the top thereof, opening and closing telescopic rods 6 are symmetrically mounted on both sides of the support seat 5, a telescopic movable seat 7 is fixedly mounted at the end position of the opening and closing telescopic rod 6, a rotating motor 8 is fixedly mounted on the telescopic movable seat 7, the main shaft of the rotating motor 8 is rotatably connected to one end of a self-locking clamping plate 9 through a connecting rod, an auxiliary support frame 14 is fixedly arranged at the bottom of the telescopic movable seat 7, the lower end of the auxiliary support frame 14 is fixedly connected to an auxiliary support telescopic rod 15, one end of the auxiliary support telescopic rod 15 away from the auxiliary support frame 14 is telescopically connected and mounted in an auxiliary support stabilizing bar 16, and the auxiliary support stabilizing bar 16 is fixedly connected to the outer side wall of the unmanned forklift body 1.

[0024] Among them, the auxiliary support stabilizing rod 16 is a square structure, and a cavity matching the size of the auxiliary support telescopic rod 15 is arranged inside the auxiliary support stabilizing rod 16. The auxiliary support telescopic rod 15 is synchronously extended and retracted with the opening and closing telescopic rod 6, and can effectively support the telescopic movable seat 7.

[0025] The clamping end of the self-locking clamping plate 9 is designed as a disc structure, and a clamping protection pad 10 is provided on the clamping surface to protect the clamped and self-locked objects and avoid damage to the objects.
