Abstract

The utility model relates to a pipe plug of a pipeline product. The pipe plug of the pipeline product is characterized in that the pipe plug comprises a pipe plug neck; at least three pipe plug valves are uniformly distributed on and connected with one end of the pipe plug neck; the external diameter of each pipe plug valve is larger than the diameter of an inner hole of a pipeline product matched with the pipe plug valve; a pipe plug cover is arranged at the other end of the pipe plug neck; and the major diameter of the pipe plug cover is smaller than the diameter of an outer hole of a pipeline product matched with the pipe plug cover. The pipe plug can effectively seal and plug the pipeline products, is easy to tightly plug and strip, prevents the deformation of the pipeline products in the stacking and storage process and has attractive and fashionable appearance, thereby improving the image of the pipeline products.

Description

A kind of pipe close of duct products

Technical field

The utility model relates to a kind of device that is used to fill in plugging road product (comprising tubing and pipe fitting etc.) mouthful end.

Background technique

Traditional pipeline opening end shutoff accessory is circular shell-like, as shown in Figure 1, mainly contains two kinds of structures, jacket-type A type pipe cap 1 and inner bearing type Type B pipe close 3, and structure is comparatively simple.A type pipe cap 1 comes shutoff mouth end to be enclosed within duct products 2 outer walls, causes 2 mouthfuls of ends of duct products exterior protrusions, and is yielding when making pipeline stack storage, and A type pipe cap 1 effectively is being difficult for taking down behind the shutoff product.Type B pipe close 3 is difficult for 2 mouthfuls of ends of jam-pack duct products, and especially inconvenient jam-pack under the motionless situation of duct products 2 is easy to come off in duct products 2 transportations and storing process.

Summary of the invention

The purpose of the utility model provides and a kind ofly is easy to the pipeline opening end plug tightly, simultaneously, can not make pipeline stack the shutoff accessory of when storage distortion again.The purpose further of the utility model provides a kind of when pipeline uses, the shutoff accessory of taking down easily.

In order to achieve the above object; The technological scheme of the utility model has provided a kind of pipe close of duct products; It is characterized in that: comprise the pipe close neck, on an end of pipe close neck, be uniformly distributed with and be connected with at least 3 pipe close lobes that the external diameter of at least 3 pipe close lobes is greater than the diameter of bore of the duct products supporting with it; On the other end of pipe close neck, be formed with pipe close lid, the big footpath of pipe close lid less than with its outer bore dia of supporting duct products.

Further, be formed with a groove respectively in the both sides of said pipe close lid.

The external diameter of said 3 pipe close lobes is than the big 1.0mm～1.5mm of diameter of bore of the said duct products supporting with it, the large diameter-ratio of said pipe close lid said with its little 0.1 mm of the outer bore dia～0.5mm of supporting duct products.

Front end at every said pipe close lobe is formed with an intilted beveled end.

The oblique angle of said beveled end is 45 °～75 °.

The formed path of the beveled end of at least 3 said pipe close lobes is less than the diameter of bore of the said duct products supporting with it.

Said path is than the little 1.5mm～2mm of said diameter of bore.

Form intilted 30 °～60 a ° inclination angle at the root of every said pipe close lobe.

The thickness that the root of every said pipe close lobe is connected to said pipe close neck is 0.8mm～1.5mm.

The wall thickness of said pipe close neck is 1.5mm～3.0mm.

A kind of pipe close that the utility model provides is the blocking pipe product effectively, and jam-pack is peeled off again easily easily, distortion in the time of can not making duct products stack storage, beautiful shape fashion, the image of riser tubing product.

Embodiment

For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.

Like Fig. 2 to shown in Figure 4, the pipe close 4 of a kind of duct products that provides for the utility model, its structure can be divided into three parts, is respectively pipe close lobe 5, pipe close neck 6 and pipe close lid 7.

Pipe close lobe 5 is formed by 3～6, be uniformly distributed with to be connected on the pipe close neck 6, D outer diameter 2 compare the big 1.0mm～1.5mm of diameter of bore d1 of supporting duct products 2, spacing A is 3mm～6mm, length B is 10mm～15mm, bending is dwindled easily; It is 45 °～75 ° that its mouthful end has designed a bigger oblique angle a, oblique angle part path D1 compare the little 1.5mm～2mm of diameter of bore d1 of supporting duct products 2, pipe close lobe 5 can be led easily fills in duct products 2; The thickness E that its root is connected to pipe close neck 6 is 0.8mm～1.5mm; Have suitable bending and strength character; Having designed oblique angle b simultaneously is 30 °～60 °, can be prone to when pipe close 4 jam-packs are in the duct products 2, produce be out of shape and swelling makes pipe close 4 difficult drop-offs.

Pipe close neck 6 D outer diameter 3 compare the little 0.5mm～1.5mm of diameter of bore d1 of supporting duct products 2, can not interfere pipe close lobe 5 jam-packs in duct products 2; Pipe close neck 6 wall thickness F are 1.5mm～3.0mm, keep having suitable tension force behind institute's connection plug lobe 5 jam-packs.

Pipe close lid 7 big footpath D4 compare the little 0.1～0.5mm of outer bore dia d2 of supporting duct products 2, distortion in the time of can not making duct products 2 stack storage; Designed two grooves of symmetry, recess width H is 0.8mm～1.2mm, can use instrument or the manual pipe close of peeling off easily when using duct products 2.

In the utility model, pipe close lobe 5 structures of pipe close 4 have been used for reference the attachment portion and the catenation principle thereof of flexible pipe mechanical fastener, and this mechanical fastener is rigid joint, form sealing through an amount of distending flexible pipe.Pipe close lobe 5 adopt be uniformly distributed with cut 3～6 grooves realize its easily bending dwindle, can lead easily and fill in duct products 2.Increasing pipe close neck 6 is in order to have suitable tension force; Increasing pipe close lid 7 is to peel off easily again for easy jam-pack.
