Joint device under integrated control for turning gear

The utility model provides a joint device under integrated control for a turning gear. A handle is connected with a valve core through a hinge; the middle part of the handle is provided with a groove which is cooperatively connected with a supporting shaft; both the centers of a cambered groove of the handle and a cambered shaft of a supporting shaft are positioned on a central line of the valve core; the supporting shaft is fixedly connected to a valve body; the middle part of the valve core is connected with the valve body through clearance fit; the upper part of the valve core is provided with a spring seat, a spring and a gasket in sequence; the lower part of the valve core is connected with a shift fork through a spline; the middle part of the valve core is connected with the valve body through clearance fit; the middle part of the valve core is provided with an annular groove; when the spring is at a natural position, through holes are formed in the valve body at the positions on the lower part of the annular groove of the valve core in three directions and are fixedly connected with an oil inlet, a turning gear device oil supply hole and an adjusting valve oil supply hole respectively. The handle can only be turned to join the device after an oil supply passage is opened by pressing the handle, so that the joint device is in a lubricated state; the device has the characteristics of easiness in machining, convenience in mounting and disassembly, small size, light weight and capability of reliably guaranteeing oil spray lubrication of the turning gear device for a long time.
