Abstract
The utility model relates to a pipeline plug and particularly provides an underground embedded pipe plug, which solves the problem in the prior art that existing underground embedded pipes are lack of special plugs. The underground embedded pipe plug comprises a plug plate, a rubber ring, a clamping plate, a connecting stud and a nut. The edge of a circle enclosed by the plug plate and the clamping plate is respectively provided with a semi-groove and the two semi-grooves are mutually matched to form a clamping rubber ring groove. The connecting stud is fixedly arranged at the center of the plug plate. The center of the clamping plate is provided with a hole for the connecting stud to pass out of the clamping plate. The nut is screwed onto the connecting stud, so that the plug plate and the clamping plate are tightly pressed. Meanwhile, the rubber ring is tightly pressed between the two semi-grooves of the plug plate and the clamping plate. According to the technical scheme of the utility model, by means of the underground embedded pipe plug, the end portions of a protect ion pipe are reliably sealed and are not easy to fall off. Meanwhile, the underground embedded pipe plug can be assembled or disassembled through only moving one nut, thus being very convenient in operation. The underground embedded pipe plug can be applied to various pipelines and is particularly applicable to reserved cable protecting tubes for underground power transmission.
Description
technical field
The utility model relates to pipe stopper, is specially underground preburied pipe plug.
Background technology
Modernized City Construction and road reformation, for underground transmission has been reserved cable protecting tube.To cabling, between the time of completion, for exempting from silt, pour into, need the shutoff mouth of pipe.Lack at present special-purpose plug.Current practice is: with plastic film, fabric, wrap up the mouth of pipe and tie up with rope along pipe end cylindrical; Or clog the mouth of pipe with flexible objects spheronizings such as plastic film, fabrics, and these two kinds of methods all easily come off, and imprecision is unreliable, uses inconvenient.
Summary of the invention
The utility model solves the problem that underground preburied pipe lacks special-purpose plug, and a kind of underground preburied pipe plug is provided.
The utility model is to adopt following technical scheme to realize: underground preburied pipe plug, by closure plate, cushion rubber, clamping plate and connecting stud, nut, formed, after being respectively equipped with and cooperatively interacting, the circumferential edges of closure plate and clamping plate forms half groove of clamping aprons slot, connecting stud is fixed on the center of closure plate, the center of clamping plate has the hole passing for connecting stud, nut screwing clamping, on connecting stud, and compresses closure plate and clamping plate cushion rubber is pressed between closure plate and the two halves groove of clamping plate circumferential edges.During use, first closure plate is inserted to pillar G port, then cushion rubber is embedded in half groove of closure plate circumferential edges and the groove of pillar G inwall formation.Then clamping plate are through on connecting stud, push in pillar G, and with nut, clamping plate are compressed.Closure plate, clamping plate are during cushion rubber axial compression, and circumferentially extending, tightly withstands on pillar G inwall, and the gap of having eliminated the two, realizes the sealing of pillar G termination.
Underground preburied pipe plug described in the utility model is termination and the difficult drop-off of sealing protecting tube reliably, and the only moving nut of handling is very convenient.Be applicable to various pipelines, be specially adapted to the reserved cable protecting tube of underground transmission.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-closure plate, 2-cushion rubber, 3-clamping plate, 4-nut, 5-connecting stud, 6-tappet mouth circle, 7-half groove.
Embodiment
Underground preburied pipe plug, by closure plate 1, cushion rubber 2, clamping plate 3 and connecting stud 5, nut 4, formed, after being respectively equipped with and cooperatively interacting, the circumferential edges of closure plate 1 and clamping plate 3 forms half groove 7 of clamping aprons slot, connecting stud 5 is fixed on the center of closure plate 1, the center of clamping plate 3 has the hole passing for connecting stud, nut 4 is tightened against on connecting stud 5, and closure plate and clamping plate are compressed and cushion rubber 2 is pressed between closure plate and the two halves groove of clamping plate circumferential edges.During concrete manufacture, the connecting stud at closure plate 1 middle part is provided with tappet mouth circle 6 around, and clamping plate 3 middle parts are provided with the caviton mouth matching with tappet mouth circle 6, to realize the assembling and positioning between closure plate and clamping plate.Tappet mouth circle 6 tall and big in cushion rubber 2 inner cylinder faces wide 1/2; The height that is deeply greater than tappet mouth circle 6 of caviton mouth.Cushion rubber 2 cross sections are trapezoidal, and upper base is positioned at the inner cylinder face of cushion rubber 2, go to the bottom and are positioned at the external cylindrical surface of cushion rubber 2.The shape of half groove 7 and cushion rubber 2 coincide.
