4results about How to "Won't get stuck" patented technology

The application belongs to the field of vehicle equipment and relates to a compact hydraulic tail door with a lifting function and a control method thereof. The tail door comprises a tail door body and a tail door rotating shaft fixedly connected to one side of the tail door body. The first piston rod is hingedly connected to the tail door rotating shaft and is further connected to the tail door rotating shaft through a helical gear mechanism, so that the tail door can drive a heavy object to vertically lift and has a turnover opening function. The tail door has the advantages of compact structure, reliable locking, stable action, strong impact resistance and non-stuck, and can be widely applied to vehicles that require the tail door to have the functions of driving a heavy object to lift and turnover opening and closing.

The invention relates to the field of integrated circuit manufacturing, in particular to a circuit board lamination positioning and pressing device based on conical surface guiding, which comprises a laminating table, a hydraulic rod is arranged on the upper end surface of the laminating table, a hydraulic cylinder is arranged at the upper end of the hydraulic rod, an upper pressing plate is fixedly connected to the lower end of the hydraulic rod, and a laminating platform is arranged in the laminating table. A lower pressing plate is arranged on the upper end face of the laminating platform, the horizontal projection of the lower pressing plate is completely located in the laminating range of the upper pressing plate, a hydraulic hole is formed in the upper end face of the lower pressing plate and arranged in the circumferential direction of the lower pressing plate, a hydraulic cavity is formed in the lower end in the hydraulic hole, a pressing block is arranged in the hydraulic hole, a through hole is formed in the center of the pressing block, and a conical face column is arranged in the through hole. The upper pressing plate is provided with a locking hole, the locking hole is matched with the conical surface column, the positioning effect is continuously enhanced in the whole pressing process, the layer deviation problem of circuit board lamination pressing is fundamentally reduced, and the alignment precision and the pressing stability of the upper pressing plate and the lower pressing plate are greatly improved.

This invention relates to the technical field of stand-on reach trucks, specifically an automatic control system for a stand-on reach truck. It includes a frame, a drive mechanism, and a control system. A pair of load-bearing wheel assemblies are mounted on a pair of front legs of the frame. The drive mechanism includes an L-shaped drive axle, a drive axle shaft, an auxiliary wheel assembly, and a drive wheel assembly. The control system includes a hydraulic system and a cylinder adjustment mechanism. The hydraulic system includes a solenoid valve, a hydraulic multi-way valve, a controller, an oil pump motor, and a hydraulic pump. Therefore, the drive mechanism of this invention is connected to the frame via the drive axle shaft. The L-shaped drive axle, i.e., the auxiliary wheel assembly and the drive wheel assembly, can rotate appropriately around the drive axle shaft. This allows the entire drive mechanism to adjust appropriately according to road conditions. Simultaneously, the reliable hydraulic system can precisely control the force on the drive wheel assembly and the auxiliary wheel assembly, automatically adjusting their states according to road conditions and forming feedback regulation.

This utility model discloses a washing device, relating to the field of lithium-ion battery manufacturing technology. The washing device includes a tank, a stirring assembly, and a washing assembly. A filter disc is disposed within the tank, and the material to be washed is located on the filter disc. The tank is connected to a feed pipe. The stirring assembly includes a stirring paddle, which is rotatably disposed within the tank and above the filter disc. The stirring paddle is capable of moving up and down within the tank. The washing assembly is disposed within the tank and above the stirring paddle, and is configured to supply washing liquid to the tank. This washing device prevents the stirring paddle from jamming, and the stirring paddle does not interfere with the operator's ability to remove precursor particles from the washing device, thus improving production efficiency.
