Abstract
The utility model relates to a fast connecting joint of a plastic pipe. The fast connecting joint comprises a joint body which is made of plastics. A fast connecting port is formed in the joint body, and a bushing, a clamping spring, a cushion and a sealing ring are sequentially arranged on the inner wall of the fast connecting port from outside to inside. A clamping rib and a clamping groove which are mutually matched are arranged between the bushing and the inner wall of the fast connecting port, and the clamping spring, the cushion and the sealing ring are fixed at the fast connecting port through the bushing. A moving ejecting block is arranged on the inner side of the bushing, and protruded blocks which are mutually matched are arranged between the outer wall of the moving ejecting block and the inner wall of the bushing. Due to the protruded blocks, the ejecting block will not be disengaged from the fast connecting port. The fast connecting joint of the plastic pipe has the advantages of being convenient and fast to install and detach, capable of saving working hours of installation and good in sealing effect.
