Mechanism；Position-limited rack include being used for being fixed on the mouth of pipe it is cylindrical on clip, support block, support block one end is connected with clip, support block
The other end is provided with the closing piece for being used for locking/unclamp clip；Hold-down mechanism is included on cam, the handle being connected on cam, cam
Eccentric orfice is provided with, rotating shaft one of the cam through being plugged in eccentric orfice is hinged with support block.
Cam mounting hole, the hinge hole being connected with cam mounting hole are provided with the support block, cam one end is stretched into convex
Wheel mounting hole is interior, the rotating shaft one through being plugged in hinge hole and eccentric orfice is hinged with support block.
Described support block one end is connected through contiguous block with clip.
The contiguous block two ends are hinged through rotating shaft two with support block, clip respectively.
Described closing piece one end is hinged with support block, and the closing piece other end is provided with locked groove, and clip, which is provided with, to be used to coordinate locked groove
Lock pillar.
The clip includes left half clip, right half clip, the buckle for left half clip of clamping/release and right half clip,
Left one end of half clip and one end of right half clip are hinged by rotating shaft.
Described buckle one end is hinged with the other end of left half clip or the other end of right half clip, the other end of left half clip
Or the other end of right half clip is provided with neck, the buckle other end is corresponding with neck.
Annular groove is provided with the blanking cover, the sealing ring for sealing orifice is loaded in annular groove.
Also include being provided with pilot hole on more than one in more than one guide rod for being used to position blanking cover position, support block,
It is provided with more than one lower pilot hole corresponding with upper pilot hole on blanking cover, guide rod is plugged in pilot hole, in lower pilot hole.
The upper pilot hole coordinates with guide rod for gap, and lower pilot hole is interference fit with guide rod.
Compared with prior art, frock making is simple, and small volume, cost is low by the present invention, with easy to operate, structure letter
Single, reliable, easy to manufacture, cost is low, the features such as be readily produced.Solve in tubing product pressure testing, mouth of pipe closure efficiency is low
Lower and unstable the problem of, the time can be saved again, operating efficiency is improved, can obtain wide in the pressure testing process of pipe part
General application.
