Abstract

The invention relates to a tipping locking control device of a dynamic tray. The tipping locking control device comprises a first base, a second base which rotates leftwards and rightwards around thefirst base, a second crank with one end hinged to the second base and the other end hinged to a bearing part, a warping plate which is connected with the second crank to form a whole, a warping platelocking control mechanism which comprises a sliding locking piece and a plurality of clamping grooves, wherein the clamping grooves are formed in a vertical plate of the second base from top to bottom; long grooves are further formed beside the clamping grooves; the long grooves communicate with the clamping grooves; the sliding locking piece comprises a main body part and a bifurcated rod with alocking pin; the second crank is in sleeved fit with the locking pin through a waist-shaped hole; in an unlocking state, the locking pin slides into the corresponding long groove along the waist-shaped hole, and the warping plate freely rotates; and in a locking state, the sliding locking piece slides for enabling the locking pin to enter the corresponding clamping groove along the waist-shaped hole, so that rotation of the warping plate is limited. According to the tipping locking control device, space is fully utilized and rotation of the second base is not impeded.
