Wherein, the horizontal plate 21 and the vertical plates 22 at two sides thereof form a rectangular open slot 23, and the adjusting screw 1 penetrates into the open slot 23.

In one of the embodiments, the pipe leakage blocking device with pressure further comprises a positioning sleeve 6, one end of the positioning sleeve 6 is fixed to the vertical plate 22 on one side of the transverse plate 21, the other end of the positioning sleeve 6 is fixed to the vertical plate 22 on the other side of the transverse plate 21, and the adjusting screw 1 is simultaneously arranged in the threaded hole and the positioning sleeve 6 in a penetrating mode, so that the positioning effect is achieved on the adjusting screw 1, and the leakage blocking effect is prevented from being influenced by the fact that the adjusting screw 1 inclines.

Further, the positioning sleeve 6 may also be provided with threads therein for cooperation with the adjusting screw 1.

In one embodiment, the bottom of the arc-shaped pressing plate 3 is connected with a rubber pad 4, so that the rubber pad 4 is in contact with a leakage point of a pipeline, and the sealing effect of the leakage point is improved.

Further, the thickness of the rubber pad 4 can be 12 mm-30 mm; the adjusting screw 1 has a diameter of 40 mm.

in one embodiment, a rotating rod 5 is connected to one end of the adjusting screw 1 far away from the arc-shaped pressing plate 3, so that the adjusting screw 1 can be rotated to adjust the screwing length.

In one embodiment, the rotary rod 5 and the adjusting screw 1 are perpendicular to save the rotating force.
