Abstract
The invention discloses an expansion sealing plug, comprising a screw, a nut and an expansion part; the expansion part is provided with an internal hole which is passed through by the screw to be connected with the nut; a washer is arranged between the expansion part and the nut. When the pipe is required to be sealed, the nut can be screwed by hand in order to lead the expansion part to be sufficiently contacted with the screw head and the washer; after that, the expansion sealing plug is arranged in the internal hole, and the nut is screwed; owning to the sufficient contact between the screw head and the end surface of the expansion part with a certain friction force, when the nut is screwed, the screw is not synchronously rotated; therefore, the expansion part is extruded by the screw head and the washer in the screwing process of the screw; the tighter the screwing is, the greater the extrusion force is and the greater the expansion part expands; the expansion of the expansion part can sufficiently extrude the internal wall of the pipe, thus sealing the pipe by the expansion. The invention is suitable for the sealing or connection of all pipes, with good sealing, firm connection and extreme convenience and practicability.
Description
Technical field
The invention relates to a kind of sealing arrangement, more particularly, it is about a kind of buckling sealing plug.
Background technology
Being used for pipe fitting leak free device now has a lot, and chock plug sealing, screw thread fit sealing etc. are arranged, but these all have leak tightness difference or can only disposable shortcoming.Just do not re-use after for example Wine bottle block is generally opened, the general leak tightness of bottle stopper of opening the back drinks is relatively poor, leaks gas easily.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, a kind of good airproof performance is provided, is connected firmly, repeatedly used buckling sealing plug.
The objective of the invention is to be achieved by following proposal.
Buckling sealing plug of the present invention comprises screw, nut, expansion piece, and expansion piece is provided with endoporus, and screw is connected with nut by the expansion piece endoporus, is provided with pad between expansion piece and the nut.The head outer diameter of screw is greater than the expansion piece endoporus, less than the expansion piece external diameter.The screw rod external diameter of screw is less than the expansion piece endoporus.The pad external diameter is greater than the expansion piece endoporus.
Advantage of the present invention is:
1, good airproof performance, be connected firmly.
2, easy to use, with low cost.
Description of drawings
Fig. 1 is a decomposing schematic representation of the present invention
Fig. 2 is an assembly drawing of the present invention
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
Fig. 1 is a decomposing schematic representation of the present invention, comprise screw (1), nut (4), expansion piece (2), expansion piece (2) is provided with endoporus, so that screw (1) is connected with nut (4) by expansion piece (2) endoporus, is provided with pad (3) between expansion piece (2) and the nut (4).When wanting sealed pipe fittings, can use hand-screw jack panel (4) earlier, expansion piece (2) is fully contacted with pad (3) with screw (1) head, as Fig. 2, then buckling sealing plug is filled in endoporus, turn nut (4) because screw (1) head fully contacts with expansion piece (2) end face, has certain friction, during nut (4) turn, not turn synchronously of screw (1) because pad (3) fully contacts with expansion piece (2) end face, has certain friction, during nut (4) turn, pad (3) is not turn synchronously also, thus nut (4) in screwing process, screw (1) head and pad (3) can extrusion expansion spares, revolve to such an extent that tight more squeese pressure is big more, expansion piece (2) expands greatly more, and the expansion of expansion piece (2) can fully be pushed pipe fitting inner wall, has reached by expansion to make pipe fitting leak free purpose.
