The invention relates to a winged jump-type wooden lock with wooden tenon-and-mortise structure for drawers, which comprises a crossbeam, a wood lock cavity, a winged jump-type wooden lock. The crossbeam is arranged at the bottom of the drawer, and the direction of the crossbeam is the same as the drawing direction of the drawer.The wooden lock cavity is arranged at a position near the front plateof the drawer on the crossbeam, and the winged jump-type wooden lock is arranged in the wooden lock cavity.The winged jump-type wood lock comprises a pin shaft and a long strip wooden block. The pinshaft fixes the long strip wooden block into the wood lock cavity. The long strip wooden block rotates around the pin shaft which is arranged at the 2 / 3 position of the long strip wooden block. When the short edge of the long strip wooden block is raised, the bottom end of the back plate of the drawer is stuck. The winged head-type wooden lock with the wooden tenon-and-mortise structure for the drawershas the advantages of simple structure and safe use, and can avoid automatic sliding or falling of the drawers.

The invention relates to the field of processing of polarizing films, in particular to automatic positioning packaging and attaching equipment of a polaroid and a production technology thereof. The equipment comprises a machine body, a cutting mechanism, a drawing mechanism, an up-rolling mechanism and a thin film removing mechanism which are arranged in the machine body. The machine body comprises two slide rails in approximate L shapes, the slide rails are horizontally arranged, a guide pulley is arranged in each slide rail respectively, the drawing mechanism can be movably arranged betweenthe two guide pulleys in the extending direction of the slide rails through the two guide pulleys, the up-rolling mechanism is arranged at the tail ends of the slide rails and can be vertically or horizontally and movably arranged through a linkage device, an attaching shaft capable of rotating around the axis is arranged between the tail ends of the two slide rails, an extending mechanism used for driving the attaching shaft to move vertically is arranged at the end of the attaching shaft, the thin film removing mechanism can be movably arranged to be directly close to or away from the attaching shaft through a hydraulic rod, and an anti-warping piece is arranged at the turning part of each slide rail. The automatic positioning packaging and attaching equipment of the polaroid can cut thepolaroid automatically and locate the end part of drawn and pre-attached polaroid.

The invention provides a watt linkage mechanism, an auxiliary walking stabilization mechanism, a walking mechanism and a robot. The watt linkage mechanism comprises a first linkage and a second linkage, and the first linkage and the second linkage are rotationally connected through a middle rotating connecting piece; the first linkage is connected to a fixing shaft of the middle rotating connecting piece, and the second linkage is connected to a rotating shaft of the middle rotating connecting piece; the first linkage and the second linkage are correspondingly connected with an auxiliary wheelmechanism with the same structure, each auxiliary wheel mechanism comprises an auxiliary wheel movable bracket, and first auxiliary wheels are installed on the auxiliary wheel movable brackets; the auxiliary wheel movable brackets are rotationally connected with the corresponding linkage through movable shafts of the auxiliary wheel movable brackets; the auxiliary wheel movable brackets can rotate around fixing shafts of the auxiliary wheel movable brackets by a certain angle to drive the first linkage to move correspondingly; the middle rotating connecting piece can rotate around the fixingshaft of the middle rotating connecting piece to drive the second linkage to move correspondingly; and the movement of the corresponding linkages drive the corresponding auxiliary wheel movable brackets to rotate, and thus the corresponding auxiliary wheels are driven to move in the vertical direction.
