The utility model belongs to the technical field of
medical instruments, and particularly relates to a
urine collecting
barrel, a containing cavity is used for containing
urine of a patient, an upper cover is used for covering the containing cavity to prevent dust or other impurities from entering the
barrel to pollute the

assembly through a rotating block to lock the upper cover and a
barrel body. When the upper cover is not fixed to the barrel body, the upper cover can be easily taken out, the interior of the barrel body can be conveniently cleaned, and liquid in the barrel body can be conveniently poured out, and when the liquid is contained in the barrel body, the upper cover and the barrel body are fixed through the first locking
assembly and the second locking assembly when the upper cover is placed at the barrel opening. Liquid in the containing cavity is isolated from external air, the rotating
handle is arranged on the side, opposite to the rotating block, of the upper cover, when the upper cover is installed, the side, provided with the rotating block, of the upper cover faces the containing cavity, the rotating
handle faces the outer side at the moment, and when the upper cover and the barrel body need to be fixed, only the rotating
handle needs to be rotated from the outside.
