[0004] The technical solution adopted by the utility model is a reinforced polyethylene elbow, which includes an elbow body. The elbow body includes an upper elbow, a first clamping device and a second clamping device. A limiting groove is arranged in the clamping wall of the upper elbow, a rubber pad is arranged in the upper elbow, the upper elbow is connected to the elbow main body, the elbow main body is connected to the lower elbow, an elastic rubber is arranged in the elbow main body, a first buffer slope, a second buffer slope and a third buffer slope are arranged on the elastic rubber, an external rubber strip is connected to the outer wall of the elbow main body, and a limiting rubber block is arranged on the external rubber strip. The first clamping device includes an upper hoop cover, a lower hoop cover, a bolt and a bolt cap. The second clamping device includes a lower tightening ring, the lower tightening ring is connected to a short rod and a lower connecting rod, the two sides of the short rod are respectively connected to a first tightening belt and a second tightening belt, the lower connecting rod is connected to a shaft, the shaft is connected to an upper connecting rod, the upper connecting rod is connected to an upper tightening ring, and the upper tightening ring is connected to a circular ring.

[0005] The height of the third buffer slope is higher than that of the second buffer slope, and the height of the second buffer slope is higher than that of the first buffer slope.

[0006] The length of the first tightening belt is greater than that of the second tightening belt.

[0007] The upper tightening ring is of a hollow structure.

[0008] Advantages of the present utility model: The integrated elbow is divided into three parts: the upper elbow, the elbow body, and the lower elbow. The three parts can be individually disassembled for maintenance and cleaning. The three parts are clamped and stabilized by the first clamping device and the second clamping device, and the operation is simple. Elastic rubber is added inside the elbow body, and rubber pads that connect with the elastic rubber are added inside both the upper elbow and the lower elbow, enhancing the thickness of the vulnerable parts of the elbow. The first buffer slope, the second buffer slope, and the third buffer slope are arranged step by step on the elastic rubber, which can reduce the flow rate of the liquid passing through the elbow and the impact force of the liquid on the elbow, making the elbow more durable.
