Abstract
The utility model discloses a device for fastening a live knot of a PVC pipeline, which comprises an upper flange, a lower flange and penetrating screws and is characterized in that either the upper flange or the lower flange is formed by splicing two semicircles, holes are arranged at the splicing joints of the two semicircles which are connected by the screws into a whole flange. The device drives the live knot of the PVC pipeline to retract by the compression of the two flanges towards the center so as to provide a simple and practical tool for preventing the pipeline from being bent due to seasonal change.
Description
Technical field
The utility model relates to a kind of instrument, relates in particular to pipe running tool.
Background technique
The flexible piston joint in traditional pvc pipe road can stretch out additional shortening amount from movable joint when the shrinkage of pvc pipe road, when with the seasonal variations heat expansion, in the ineffective movable joint of elongation can not being withdrawn of piston joint, and cause the bending of indoor PVC water supply line compressive deformation.The one, influence attractive in appearance, the 2nd, cause ground fixing glue between the floor to come off to make upstairs floor maceration water below the course.
Summary of the invention
The utility model provides a kind of device that is used for fastening pvc pipe road movable joint for solving the pvc pipe road movable joint problem of can not withdrawing automatically.
For achieving the above object, the utility model comprises upper and lower two flange plate and runs through screw rod, it is characterized in that, upper and lower two flange plate form by two semicircle overlap joints, and two semicircle lap-joints are provided with corresponding hole, connect into the integral (type) flange dish by screw rod.
During use, open the pipe joint place at the piston joint two ends of being inserted in PVC behind upper and lower two flange plate respectively, with screw rod the flange plate two ends are connected into whole circle, all the other holes of flange plate penetrate with screw rod, adjust nut, make two flange plate to intermediate compression, force the movable joint withdrawal of pvc pipe road, till whole pipe is proofreaied and correct.
The utility model good effect is: for the pvc pipe road provides a kind of simple and practical instrument because of the bending that seasonal variations produces.
Description of drawings
Further specify technology contents of the present utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model embodiment's a plan view, and screw rod does not draw among the figure;
Fig. 2 is the plan view of Fig. 1.
Among the figure: 1-upper flange plate, 2-hole, 3-screw rod, 4-lower flange.
Embodiment
As depicted in figs. 1 and 2, the utility model comprises upper flange plate 1, lower flange 4 and runs through screw rod 3, and upper flange plate 1 and lower flange 4 form by two semicircles overlap joints, and two semicircle lap-joints are provided with corresponding hole 2, connect into the integral (type) flange dish by screw rod 3.
