Abstract
The utility model discloses a drawer propelling mechanism capable of locking position. The drawer propelling mechanism comprises a support group, a screw rod, a drawer separating plate, a screw nut, a guide plate capable of sliding back and forth relative to the support group, a positioning rod capable of sliding up and down relative to the support group, and a position limiting block fixedly arranged on the drawer separating plate. Rotation limiting structure of the screw rod is disposed between the screw rod and the guide plate. Rotating state of the screw rod is limited if the guide plate is at a rotation-limiting position, while the rotating state of the screw rod is permitted if the guide plate is at a rotation-permitting position. An inclined groove is arranged on the guide plate. The positioning rod is fixedly connected with a pin which is matched with and connected with the inclined groove. The position limiting block presents concave-convex structure along the front and rear line. The concave-convex structure comprises a convex part and a concave part between which a stepped surface is formed. The bottom of the positioning rod is matched with the position limiting block so that when the positioning rod is located at the concave part and leans against the stepped surface, the guide plate can be prevented from sliding so as to be kept at a rotation limiting position. The drawer propelling mechanism is advantageous in that a drawer can be locked when sliding to a given position, preventing a misoperation.
