This utility model relates to the field of pneumatic cabinet technology, proposing a pneumatic cabinet structure that is easy to maintain. The structure includes a cabinet body, a first side mounting compartment located at the bottom of one outer wall of the cabinet body, and a water supply unit fixedly connected to the interior of the first side mounting compartment by screws. A second side mounting compartment is located at the bottom of the other outer wall of the cabinet body. This utility model installs the water supply unit, air pump, and solenoid valve in separate first and second side mounting compartments, respectively. Furthermore, the main electrical installation room and auxiliary electrical installation room are arranged in layers, achieving clear functional zoning, avoiding wiring and piping intersections, and effectively improving maintenance efficiency. The double-door design of the top and bottom cabinets allows for independent maintenance of different functional areas without the need for complete cabinet disassembly. In addition, the centralized arrangement of cooling water and air source interfaces further simplifies external connections and improves space utilization.

The utility model relates to a fork truck control technical field, concretely provides a fork truck drive lift control oil circuit system, including inverted L type structure support, the side end of support is equipped with oil pump, is equipped with lifting cylinder in upper end, the support is opened in and simultaneously penetrates the upper oil passage and oil return passage of upper end and side end of support, the oil return passage is connected with the oil return pipeline and is inserted, and the upper end of oil return pipeline is connected to the side of lifting cylinder close to the upper end, the utility model discloses the built -in hidden design of hydraulic pipeline, carries out the protection design to oil return pipeline, realizes the thorough innovation of fork truck drive system oil circuit layout, can fundamentally eliminate the damage and leakage risk of pipeline because of external collision, scraping and environmental erosion, significantly improves the operation safety and reliability of system, still optimizes the space utilization through the high integration design, makes the structure more compact.

This utility model discloses a control box, including a lower box and an upper box that cooperate with each other. The lower box has a first groove and a first protrusion on its contact side; the upper box has a second groove and a second protrusion on its contact side. During assembly, the first protrusion is located within the second groove, and the second protrusion is located within the first groove. The lower box has an air pipe connection port on its outer side, containing an air pipe connector for connecting to external equipment to detect liquid level and hydraulic pressure. The lower box contains a fixing plate and a solenoid valve mounting seat. A mounting plate is mounted on the fixing plate, and an integrated circuit board and a battery are mounted on opposite sides of the mounting plate. The solenoid valve is mounted on the solenoid valve mounting seat, and a negative pressure switch and a liquid level switch are mounted inside the lower box. A first sealing ring and a second sealing ring are respectively provided in the first and second grooves, forming a double seal in conjunction with the arc-shaped protrusion. Both the lower and upper box have U-shaped mounting openings on their outer sides. This utility model has the advantages of high integration, high protection level, and convenient installation and maintenance.
