Specific embodiment

Explanation is further explained to the utility model with reference to the accompanying drawing, but does not limit the protection model of the utility model It encloses.

In the description of the present invention, it should be noted that term " on ", "lower", "left", "right", "inner", "outside" etc. The orientation or positional relationship of instruction is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description the utility model It is described with simplifying, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific orientation structure It makes and operates, therefore should not be understood as limiting the present invention.

Fig. 1-3 is please referred to, the utility model provides a kind of technical solution, and anti-piptonychia pipe is followed successively by anti-knocking over from left to right 1, gland 2, washer 3 and first pipe 4, wherein anti-knocking over 1 is detachably connected by the stay bolt 5 through gland 2 with first pipe 4, gland 2 It is detachably connected by lag bolt 6 and first pipe 4, and washer 3 is set between gland 2 and first pipe 4, the anti-knocking over 1 is by two The side of the annular structure that a semicircular ring 7 forms, two of them semicircular ring 7 is flexibly connected by connecting shaft 8, and the other side is all provided with There is positioning through hole, and is equipped with fastening bolt 9 in positioning through hole.

Wherein, in the present embodiment, the first pipe 4 is the tubular structure for being provided with ring flange, and first pipe 4 is from the inside to the outside It is followed successively by wearing layer 10, enhancement layer 11, interior base 12 and corrosion-inhibiting coating 13.Wearing layer 10 improves between first pipe 4 and pipeline Connective stability, and enhancement layer 11 and corrosion-inhibiting coating 13 further increase the intensity and antiseptic property of first pipe 4, extend first The service life of pipe 4.
