Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve technology, specifically a hydraulic composite valve. Background Technology

[0002] Chinese patent document CN218151748U discloses a cylinder-type composite hydraulic directional valve. This valve is installed on the outer surface of the fixed end of a single-acting hydraulic lifting cylinder in a dump truck. The composite hydraulic directional valve is a pneumatically controlled composite hydraulic directional valve, comprising an integral hydraulic directional valve body, an inlet port P, an outlet port T, a single-acting cylinder interface C, an open-cover port B, a closed-cover port B1, and a pneumatic control component. Compared to existing technologies, this invention solves the problems of having to install the composite hydraulic directional valve on the chassis frame and connect it with hydraulic hoses, resulting in numerous hoses, messy and disorganized installation, large space occupation, high manufacturing costs, and an unsightly appearance. The single-acting cylinder interface C is detachably connected to the port on the fixed end of the dump truck's hydraulic lifting cylinder, eliminating the need for hoses.

[0003] However, in the above-mentioned solutions and existing technologies, the existing hydraulic composite valves usually require operators to use auxiliary tools to tighten bolts to fix the main body of the hydraulic composite valve to the equipment body during use. This is inconvenient and affects the disassembly and maintenance efficiency of the hydraulic composite valve, and needs to be improved and optimized. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic composite valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic composite valve, comprising: a composite valve body, mounting plates symmetrically fixed on both side walls of the composite valve body, the composite valve body being mounted on mounting bosses via connecting components, the mounting bosses being symmetrically fixed on the equipment body, and the mounting plates being snapped into the mounting bosses; square grooves symmetrically opened on the mounting bosses, a turntable being rotatably mounted within the square grooves, and the connecting components including locking pins and L-shaped plates.

[0006] Preferably, a positioning post is fixedly provided on the mounting boss, a positioning hole is provided on the mounting plate, the positioning post is inserted into the positioning hole, a locking post is fixedly provided at the end of the turntable, and a limit plate is fixedly provided at the end of the locking post.

[0007] Preferably, the movable sleeve on the locking post is provided with a sleeve and a fixing ring, the fixing ring is fixedly provided on the side wall of the sleeve, and a spring is sleeved on the locking post, with both ends of the spring being fixedly connected to the limiting plate and the fixing ring respectively.

[0008] Preferably, the mounting plate has symmetrical slots and circular grooves that extend through the slots, with the locking post engaging with the slot and the sleeve inserting into the circular groove.

[0009] Preferably, the mounting plate is provided with symmetrical trapezoidal grooves, and a trapezoidal slider is movably engaged in the trapezoidal groove. The trapezoidal slider is fixedly mounted at the bottom of the L-shaped plate. Arc groove clamping plates are symmetrically fixed on both sides of the L-shaped plate. An annular groove is provided on the peripheral wall of the sleeve, and the arc groove clamping plate is engaged with the annular groove.

[0010] Preferably, the L-shaped plate has a hook groove on its side wall, and elastic hooks are symmetrically fixed on both sides of the composite valve body. The hook groove engages with the elastic hook. A fixing plate is fixed on the side wall of the L-shaped plate, and a post is fixed on the side wall of the fixing plate. A slot is provided on the side wall of the mounting boss, and the post engages with the slot.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By engaging the mounting plate and mounting boss with the positioning pin and positioning hole, the sleeve moves along the pin and compresses the spring of the fixing ring. Then, the turntable is rotated until the pin engages in the slot, and the spring returns to its original position, pushing the sleeve to move and insert into the circular groove. The trapezoidal slider moves along the trapezoidal groove until the hook groove engages with the elastic hook to fix the L-shaped plate position. At this time, the arc groove plate engages in the ring groove, and the insertion pin engages with the slot, thereby fixing the sleeve position so that it is stably inserted into the circular groove. This allows the hydraulic composite valve body to be quickly installed on the mounting boss of the equipment body. The operation is simple and does not require auxiliary tools, improving the disassembly and maintenance efficiency of the hydraulic composite valve. Attached Figure Description
