Description
Affiliated technical field
The utility model relates to a kind of Sealing, especially a kind of interior plug that is used for closed conduit hollow end.
Background technique
At present, the use of pipeline is very extensive, and particularly hollow pipeline generally in use requires end seal, for example with plastics claddings steel pipe corrosion-proof as planting in a kind of agricultural and the Garden Engineering pillar quite general.In order to adapt to and to satisfy the application requirements that ground corbelling and environment are planted in agricultural and gardens, plug seal arrangement in must adopting with the steel pipe two ends of plastics cladding will seal fasteningly after inserting simultaneously, be easy to construct and plant ground.The interior plug seal arrangement of Shi Yonging is single cylindrical now, structurally all there are some defectives, not only seal not ideal enough, be difficult to prevent that underground water and other MEDIA FLOW from going into the corrosion that causes the steel pipe inwall in steel pipeline and the interior plug interlayer, and fastening degree is relatively poor, directly influences the working life of construction quality and pillar.
Summary of the invention
The utility model provides a kind of high polymer resiliently deformable that relies on to fix interior plug seal arrangement with closed conduit, is applied to agricultural and plants ground support engineering corrosion-resistant pillar, metal conduit fixing seal field with gardens.
The technological scheme that realizes the utility model purpose is: a kind of end sealing plug, comprise insertion portion and exposed parts, insertion portion and exposed parts are overall structure, in order to reduce cost, reduce material, make things convenient for molding and forming, accelerate moulding speed, reduce shrinkage cavity, injection defects such as bubble are provided with blind hole at insertion portion, lead to the end of the close exposed parts of insertion portion from the outer end of insertion portion, direction is the axial direction of insertion portion, blind hole can make simultaneously insertion portion produce resiliently deformable, has excellent contact toughness, make with pipeline to be connected tightness better.
In order to have good sealing property, further be provided with: the insertion portion back segment is provided with a flexuose circumferential groove at least, according to the sealing needs, a plurality of circumferential groove can be set.Simultaneously, circumferential groove has also played when mounted chip breaking function and good sealing effect automatically.
In order to increase the friction of seal arrangement and tube wall, strengthen fixed effect, further be provided with: be provided with protruding structure at the insertion portion leading portion, protruding structure is various informative, can be spline shape structure or spherical cap-shaped structure.
With in the sealing plug insertion tube, further be provided with: be provided with tapering from front to back for convenience at insertion portion.
In addition, consider and the adaptability of pipe material characteristic, save production cost, and easy to process, it is wherein a kind of that thermoplastic resin can be PVC, PE, PP, ABS, PA.
Superiority of the present utility model is:
1. scientific design, the plasticity resiliently deformable design according to high polymer is skillfully constructed;
2. simple in structure, assembly manipulation is convenient, chip breaking automatically, and material-saving is time saving and energy saving, realizes fast installing;
3. fixing and sealability has long-lasting, and long service life is guaranteed the construction application quality;
4. cost of production is low, and the fixing and sealability of inserting in the pipeline is better than like product.

Fig. 3 is the utility model and seal for pipe joints mounting structure schematic representation.
Among the figure: 1. insertion portion 2. exposed parts 3. blind holes 4. circumferential groove 5. protruding structures 6. pipelines 7. sawtooth
Embodiment
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
A kind of end sealing plug as shown in Figure 1, comprise insertion portion 1 and exposed parts 2, adopt injection molded, insertion portion 1 and exposed parts 2 are whole body structure, its thermoplastic resin adopts PVC, PE, PP, ABS, PA is wherein a kind of, carried out architecture advances at insertion portion 1: on the one hand,, reduce cost in order to reduce materials, make things convenient for molding and forming, accelerate moulding speed, reduce shrinkage cavity, injection defects such as bubble, insertion portion 1 central shaft is provided with blind hole 3, simultaneously when installing with the sealing of pipeline 6, can make insertion portion 1 produce resiliently deformable, have good toughness, make with pipeline 6 to be connected tightness better.Consider when installing and easily seal arrangement inserted in the pipeline 6 that insertion portion 1 front end is provided with tapering with pipeline 6 sealings; On the other hand, in order to have good sealing property in use, insertion portion 1 back segment is provided with flexuose circumferential groove 4,4 of adjacent circumferential groove form sawtooth 7, sawtooth 7 is the pawl structure, make and after circumferential groove 4 enters pipeline 6, can advance to go out, played the effect of " lock ", because high polymer has certain elasticity and toughness, make crown in pipeline 6, be subjected to thrust distortion and keep fitting tightly, both had good sealing property, strengthened fixed effect again with tube wall, under the situation of having only a circumferential groove 4, outside by insertion portion 1 and pipeline 6 inwalls are fitted and are reached sealing to pipeline 6.Circumferential groove 4 has also played automatic chip breaking function, as shown in Figure 3, in seal arrangement inserts pipeline 6 o'clock, because insertion portion 1 and pipeline 6 transition fit, mouth of pipe cutting insertion portion 1 is when being inserted into circumferential groove 4 places, smear metal is broken and, and smear metal is connected with seal arrangement all the time, and remain in outside the pipeline, influence attractive in appearance.In addition, be provided with projection 5 at insertion portion 1 leading portion, as shown in Figure 2, projection 5 is various informative, can be spline shape structure or spherical cap-shaped structure, and projection 5 increases the friction of seal arrangement and tube wall, strengthens fixed effect.
