This invention discloses a hydraulic power module, its application, a hydraulic system, a fire truck, and a method. The hydraulic power module, used in the hydraulic system of a fire truck, is suitable for adjusting various hydraulic components. It includes a pressure signal pipeline for monitoring the pressure values ​​of the hydraulic system and controlling the hydraulic output. The pressure signal pipeline collects dynamic pressure values ​​of the hydraulic system in real time, forming a continuous pressure feedback signal. The pressure feedback signal is compared in real time with a preset target pressure value. If the pressure feedback signal continuously deviates from the target pressure value, a fault signal is issued. This hydraulic power module, by setting multiple hydraulic power sources, allows other hydraulic power sources to provide emergency hydraulic power when one source fails, preventing loss of hydraulic power, improving the stability of the hydraulic system, and providing emergency hydraulic power support. The accumulator absorbs pressure signal peaks, stabilizing the pressure signal.

This utility model belongs to the field of carton opening machine technology, and in particular to an opening device, including a guide rail and a connecting plate. The guide rail is connected to the frame of the carton opening machine. A connecting plate is installed on one side of the guide rail, and a support plate is fixed on the side of the connecting plate away from the guide rail. When the guide rail is activated, it moves the connecting plate, causing the connecting rope to pull the support rod. This causes the rotating rod to rotate the push plate upwards, allowing the push plate to automatically fold the short side of the carton bottom horizontally. After the push plate folds the short side, the guide rail moves the opening device back to its original position. At this time, the connecting spring contracts, pulling the rotating rod back to its original position, keeping the support rod vertical, and allowing the push plate to return to its original position. Operators only need to periodically replace the connecting spring to maintain the stable operation of the opening device, reducing the risk of malfunction, minimizing carton wear, and improving production efficiency.

This invention discloses a casement window locking system with a concealed handle, comprising a concealed handle, a transmission lock box, two first transmission rods, two connecting block components, and two lock seats. The concealed handle is connected to the lock seats, and the lock seats are respectively connected to the two first transmission rods. One first transmission rod is connected to a connecting block component, and one connecting block component is connected to a lock seat. The lock box, by incorporating the concealed handle, transmission lock box, two first transmission rods, two connecting block components, and two lock seats, allows the concealed handle to connect to the transmission lock box. The handle, in conjunction with a gear and rack mechanism, drives a sliding block to move. The sliding block then moves components inside the transmission lock box, which in turn, via the first transmission rods, moves the connecting block components, causing the connecting block components to lock or unlock the lock seats, thereby opening or locking the window sash. The overall structure is simple, practical, and reliable. The handle can be concealed within the window sash profile, resulting in a good overall viewing angle.

This invention relates to the field of shoe sole technology, specifically to a multi-color, multi-density shoe sole. The sole is formed by molding foam beads A, B, and C using a shoe sole mold. Magnetic responsive fibers are dispersed within foam beads B and C. A first foaming agent is dispersed within foam beads B, and color-developing microparticles are dispersed within foam beads C. These color-developing microparticles are composed of a mixture of photochromic material and pigment. Magnetic responsive fibers are distributed within the color-developing microparticles, and a second foaming agent is distributed within the magnetic responsive fibers. Through a combination of physical and chemical foaming, under the influence of an external magnetic field, different areas of the shoe sole exhibit regular density changes, allowing the sole to better conform to the foot and improve wearing comfort. Furthermore, based on the penetration of magnetic responsive fibers into adjacent foam beads, combined with the three-stage foaming process, the bonding strength between adjacent foam beads is improved, effectively solving the technical problems of existing bead-foamed shoe soles being prone to tearing along the weld interface and having low tear resistance.
