Description

Technical Field

[0001] This utility model relates to the field of hydraulic end assembly technology, specifically a high-efficiency and energy-saving hydraulic end assembly. Background Technology

[0002] The high efficiency and energy saving of the hydraulic end assembly mainly benefit from its unique hydraulic transmission principle. When the piston or plunger moves towards one end of the cylinder, the working volume inside the cylinder increases, creating a negative pressure that opens the inlet, allowing liquid to be drawn into the cylinder. When the piston or plunger moves towards the other end of the cylinder, the working volume inside the cylinder decreases, the liquid is compressed, and the pressure increases, opening the outlet and allowing liquid to be discharged from the cylinder. Currently, the high-efficiency and energy-saving hydraulic end assembly uses threads to fix the sealing and discharge structures. However, this method suffers from poor stability over long-term use, while bolt fixation makes disassembly difficult, presenting certain shortcomings. Therefore, we propose a new high-efficiency and energy-saving hydraulic end assembly. Utility Model Content

[0003] The present invention aims to solve the problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a high-efficiency and energy-saving hydraulic end assembly, including a hydraulic tank, a fixed plate, a throttle, and a fastening assembly. The fixed plate is arranged outside the hydraulic tank. The throttle includes an insert rod arranged on the hydraulic tank and a fixed rod arranged on the insert rod. The fastening assembly includes a fixed seat arranged at the end of the fixed rod, a spring arranged at the bottom of the fixed seat, a movable seat arranged at the bottom of the spring, a first fastening knob threaded to the left side of the movable seat, and a second fastening knob threaded to the top of the movable seat.

[0005] Preferably, it further includes a discharge assembly, a sealing assembly, a plunger assembly, and a suction assembly, wherein the discharge assembly, the sealing assembly, and the suction assembly are all arranged inside the hydraulic tank, and the plunger assembly is arranged on the right side of the hydraulic tank.

[0006] Preferably, the fixing plate is annular, and an annular groove is formed on the outside of the fixing plate.

[0007] Preferably, the insert has a hexagonal cross-section and is inserted into the sealing assembly.

[0008] Preferably, the movable seat has a circular hole, and the movable seat is slidably connected to the fixed rod through the circular hole.

[0009] Preferably, there are two fastening components, which are symmetrically distributed at the ends of the fixing rod.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: By setting a fixed plate, a throttle, and a fastening assembly, this utility model improves the fixing effect without affecting the use of the hydraulic end assembly, and at the same time facilitates the disassembly of parts. In use, the user can align the insert rod of the throttle with the sealing assembly and insert it. During the insertion process, the moving seat of the fastening assembly can be moved along the direction of the fixed rod. Due to the presence of the spring, the moving seat is not easy to move. When the moving seat moves to the appropriate position, it can be inserted into the annular groove of the fixed plate. After being inserted, tighten the first fastening knob and the second fastening knob, and the throttle can be fixed to the fixed plate by the fastening assembly. After fixing, the sealing assembly can be prevented from loosening, thus improving the fixing effect. When disassembly is required, the second fastening knob can be loosened and the moving seat can be moved towards the fixed seat until the moving seat is disengaged from the fixed plate. Then tighten the first fastening knob. After tightening, the fixed rod of the throttle can be held and rotated. The rotating throttle will drive the sealing assembly, which can then be disassembled for use. Attached Figure Description
