Abstract
A multi-petaled oblique-plane hoop and a pipe connector are described. The hoop is divided into two groups, and the hoop petals in each group are connected by means of pins, and the pins are parallel to a connecting pipe shaft. The groups are connected by using bolts, and the bolts are vertical to a pipe shaft. Each hoop petal is in a shape of a partial ring stud, in which an arc-shaped groove is formed. The upper surface and the lower surface of the groove are symmetrical partial inner cone surfaces, and the hoop petals are connected to form a clamping chain.
