Abstract
The invention discloses a drawer feed mechanism with a position locking function. The drawer feed mechanism comprises a support group, a screw rod, a drawer partition plate and a nut, and further comprises a guide plate capable of sliding back and forth relative to the support group, a positioning rod capable of sliding vertically relative to the support group, and a limiting block fixedly arranged on the drawer partition plate. A screw rod rotation-limiting structure is arranged between the screw rod and the guide plate, the guide plate limits rotation of the screw rod if the guide plate is located on a rotation-limiting position, and the guide plate allows the screw rod to rotate if the guide plate is located on a rotation-permitting position. The guide plate is provided with an inclined groove, and the positioning rod is fixedly connected with a dowel which is connected with the inclined groove in an adapted mode. The limiting block is of a concave-convex structure on a front and rear line, the concave-convex structure is provided with a convex portion and a concave portion, and a step surface is formed between the concave portion and the convex portion. The lower end of the positioning rod is matched with the limiting block to enable the positioning rod to prevent the guide plate from continuing to slide when the positioning rod is located on the concave portion and abuts against the step surface so as to enable the guide plate to be maintained at the rotation-limiting position. The drawer feed mechanism has the advantages that position locking can be achieved when a drawer slides to a set position, and misoperation is avoided.
