Abstract

The utility model relates to a plugging apparatus for a pipe end, which is formed on the screw in a pipe body. A conic board 1 rotatablely moves along with a spiral screw rod 2. The screw rod is provided with an elastic basin-shaped body 4. While in use, the plugging apparatus is put into the pipe body. One hand centralizes a guard board, and the other hand pulls and rotates the screw rod 2 to cause the conic board 1 to enter into the opening end of the basin-shaped body and to be contacted with the opening end of the basin-shaped body. The screw rod 2 is continuously rotated, and the conic board 1 moves, which can cause the basin-shaped body to expand the plugging pipe opening. The plugging apparatus for a pipe end is served as a temporary plugging pipe opening in the process of connecting the pipe body before calling it a day. The loading and the fetching are convenient. The plugging apparatus for a pipe end can be served as the general plugging tool.

Description

Plugging apparatus for pipe end

The utility model relates to a kind of pipe end plugging device.

Various gathering lines in welding process, are finished or do not have to enter in the pipeline that connects completion for preventing foreign material before the completion Working day, and the pipe end of being everlasting welds a steel plate (also being blind plate) and solves the problems referred to above, when welding for the second time it is sliced off.Like this, not only cause waste also to destroy the pipe end groove, be unfavorable for continuing to weld and influence the quality of welding.

The purpose of this utility model is to provide a kind of manual operations and the convenient pipe end plugging device that uses.

The purpose of this utility model can reach by the following technical programs: on spiral in the body, what move with screw 2 rotation is conical plate, is equipped with the elasticity bowl-shaped body on the leading screw.

The mouth end of above-mentioned conical plate path end face and bowl-shaped body 4 is relative, between on leading screw, be with return spring, and the diameter of conical plate path end face is less than the diameter of bowl-shaped body mouth end; Can be connected by body between bowl-shaped body 4 and the leading screw 1, this body end is the annular guard board 6 greater than the pipe end port; Afterburning handler is the hand hammer that coaxial line connects with bearing pin 7 on the leading screw 2, and wherein hand hammer can be used as the welding assistant tool.

Fig. 1 is a pipe end plugging device sectional drawing;

Fig. 2 is the hand hammer diagrammatic sketch that flexibly connects on Fig. 1 leading screw 2.

Below in conjunction with accompanying drawing will the utility model is described in further detail:

By shown in Figure 1,, on spiral in the body, constitute in conjunction with caliber according to the screw mechanism principle.What wherein move with screw 2 rotation is conical plate 1, is equipped with elasticity bowl-shaped body 4 on the leading screw.

Above-mentioned conical plate 1 is the common metal plate, and it simultaneously is the taper platform, forms cylinder taper platen; Minor diameter end face on the plate (frustum face) is relative with the opening end of bowl-shaped body 4, and the two (1,4) is with return spring 3 on leading screw 2, and wherein conical plate minor diameter end face should be less than the opening diameter of bowl-shaped body 4.Can be placed on the leading screw by body 8 between bowl-shaped body 4 and the leading screw 1, the two is (4 years old, 8) can rabbet by the convex-concave ring, one end face of this body has the annular guard board 6 that is equal to or greater than shutoff pipe end face convenient for work, afterburning handler is the hand hammer handle 5 that coaxial line flexibly connects with bearing pin 7 on the leading screw 2, and pommel has hammer body.

During use, plugging device from being put into by the tube sealing port, is set upright backplate 6 on the other hand, another holds hammer body, draws, and revolves leading screw, makes plate 1 enter the port and the contact of bowl-shaped body 4, continues rotation again, and plate 1 rises greatly by bowl-shaped body along with moving, but the shutoff mouth of pipe takes off hand hammer.Hand hammer can be used as common tool.

Claims

1, a kind of pipe end plugging device, it constitutes on spiral in the body, its feature: what move with screw 2 rotation is conical plate 1, the flexible bowl-shaped body 4 of cover on the leading screw.

2, pipe end plugging device as claimed in claim 1, its feature: the mouth end of conical plate path end face and bowl-shaped body 4 is relative, between on leading screw, be with return spring 3, and the diameter of conical plate path end face is less than the diameter of bowl-shaped body mouth end.

3, pipe end plugging device as claimed in claim 1, its feature: can be connected by body between bowl-shaped body 4 and the leading screw 1, the end face of this body has the annular guard board 6 that is equal to or greater than the pipe end face.
