The invention discloses a trolley lifting mechanism used for carrying surgical tools. The trolley lifting mechanism comprises a connecting rod lifting mechanism, an upper flat plate, a guide rod and an electric pushing rod, wherein the connecting rod lifting mechanism comprises four hinged parts, a left force transmission beam and a right force transmission beam; each hinged part comprises an upper hinge support base, a lower hinge support base and a hinge, wherein the hinge is arranged between the upper hinge support base and the lower hinge support base; the connecting rod lifting mechanismis fixedly arranged on the supporting plane through four lower hinge support bases, and is fixedly arranged on the upper flat plate through four upper hinge support bases; and the two ends of the electric pushing rod are separately arranged on the left force transmission beam and the right force transmission beam in a sleeving mode, and can freely move along the axial directions of the force transmission arms. The trolley lifting mechanism disclosed by the invention is compact in structure, realizes multi-point jacking and is good in stability; the electric pushing rod can horizontally move along the axis of the left force transmission arm and the axis of the right force transmission arm to reduce eccentric load amount at the two sides, so that mechanism lifting is more stable, a medical trolley can be stressed uniformly and reasonably ascended and descended, and requirements in aspect of spatial size of the medical trolley are met.

A three-dimensional corner lap joint preform and a method of forming a three-dimensional corner lap joint preform including a woven flange with one or more legs that extend from the flange. The legs may include one or more independently woven portions which allow formation of a corner without darting the leg or adding additional reinforcement. The independently woven portions may include warp fibers which are not woven into the preform. The unwoven area allows removal of a portion of the leg prior to formation of the corner, allowing the portions of the leg to overlap and form a lap joint.

The invention provides a supporting mechanism and a supporting device with the same. The supporting mechanism swings in the horizontal direction by mounting a support arm, the front end of which is mounted on various devices, to a mounting element by using a rotary torque hinge; in this way, unbalance loading generated on the friction torque generation means of the rotary torque hinge can be reduced. In order to achieve the purpose, the supporting mechanism uses a rotary torque hinge comprising a friction torque generation means; the friction torque generation means uses elastic members such as friction washers and spring washers; the upper part of a hinge shaft of the rotary torque hinge is pivoted to a mounting hole part arranged on the supporting arm; meanwhile, a bracket for supporting the supporting arm is arranged on the hinge shaft in a friction rotation mode by means of the friction torque generation means.

The invention discloses a tool magazine control system and a control method thereof, which includes: a tool magazine, the knife magazine has a plurality of knife cups, and each of the knife cups is used to accommodate a tool; a knife arm, the The knife arm is used to pick and place the tool from the tool magazine and replace the tool on the main shaft; the control unit is used to control the rotation of the tool magazine so that the knife cup corresponds to the knife arm, controlling the rotation of the knife arm to transfer the tool from the main shaft to be accommodated in the knife cup of the tool magazine or to be transferred from the knife cup of the tool magazine to a tool mounted on the main shaft superior. Adjust the tool magazine speed, tool arm speed and arrange the position of the tool in the tool magazine through the tool weight information to reduce the unbalanced load of the tool magazine, thereby improving the tool change efficiency of the tool magazine and the service life of the tool magazine. Accordingly, the workpiece has a good surface quality during the finishing process.

The invention discloses a method for using an anti-eccentric load and anti-winding device for pulsator washing machines with different barrel diameters. Four space partitions are arranged on the space partition fixing column along the circumferential direction; the lower edge of the space partition is in the shape of The outer circular arc of the bottom of the washing tub matches the arc shape, and the water guide hole is arranged on the space separator, and the water guide hole is a rectangular hole distributed on the space separator, so that the washing liquid can flow in the separate spaces of the washing bucket; A handle is provided on the upper end of the space divider fixing column; a movable divider is set on each space divider; a divider slot on the upper edge of the divider is set on the space divider, and a clamping bolt is placed for fixing the movable divider s position. The invention can prevent deformation or even damage caused by the excessive winding of clothes, reduce the unbalanced load of the pulsator washing machine during dehydration and rotation, and can especially be used on pulsator washing machines with different diameters of washing buckets.
