The invention relates to a collection device, in particular to a urine collection device for urology. The technical problem of the present invention is to provide a urine collection device for urology that can discharge excess urine and collect urine in the whole process of urination. The technical embodiment of the present invention is: a urine collection device for urology, including a frame, a guide rod, a top plate, a feed hopper, a telescopic tube, a hard tube, a joint, a hose, a piston, a spring, and a baffle etc.; there is a guide groove in the left wall of the frame body, a guide rod is installed on the top of the frame body, a top plate is connected to the left bottom of the left side of the guide rod, the top plate is located in the guide groove, and a feed hopper is connected between the inner and lower parts of the guide rod. In the present invention, bolts are provided so that when people need to flush the equipment, the bolts and threaded holes cooperate with the piston to contact with the piston, thereby preventing the piston from being impacted by the water flow and moving downward, which hinders people from cleaning the device. By setting the clamping plate, the clamping plate When in contact with the rhombic shaft, the rotation of the rhombic shaft can be blocked, thereby improving the stability of the device.
