The invention particularly relates to a drinking bucket. The drinking bucket comprises a bucket body and a bucket head. The bucket head is fixedly connected to the upper end of the bucket body. A water outlet is formed in the bucket head. A groove is formed in the upper end of the water outlet. A sealing cover is connected in the groove in a threaded fixing manner. The lower end of the water outlet and the upper end of a hollow elastic rubber sleeve are fixedly connected. According to the drinking bucket, the sealing cover is connected in the groove in the threaded manner, and a rotating shaft is arranged, so that mounting or dismounting of the sealing cover is convenient; and after a water inlet connector of a water dispenser enters the hollow elastic rubber sleeve, the tail end of the hollow elastic rubber sleeve wraps the water inlet connector of the water dispenser under the action of shrinkage force of elastic materials, then water can be sealed in the bucket body, sealing is convenient, and the water does not overflow out of the bucket body during using.
