Abstract
The invention discloses a waterproof splicing sealing sleeve for a pipe. The waterproof splicing sealing sleeve comprises a rigid sleeve of which one end can be inserted into an opening of a large-diameter pipe, wherein an inserting hole which can be sleeved with a small-diameter pipe is formed on the other end of the rigid sleeve; and an elastic sealing ring which can be closely contacted with the periphery of the small-diameter pipe is arranged on the edge of the opening of the inserting hole on the rigid sleeve. The waterproof splicing sealing sleeve for the pipe has the advantages of convenience of assembly, high sealability, simple structure and low cost.
Description
Technical field
The present invention relates to be used for guardrail, protect the grafting accessory of window tubing, relate in particular to the anti-water cutting grafting sealing shroud that is used for tubing.
Background technology
Existing guardrail, protect window and often use the syndeton that metal pipe material is pegged graft each other; This syndeton is normally offered the hole of suitable size on the large-diameter pipe material, path tubing end is put the grafting sheathing, and the end with path tubing inserts in the perforate of large-diameter pipe material together with the grafting sheathing again; Easy for installation; And do not need securing members such as screw, not only make guardrail, to protect window handsome in appearance, and eliminated the potential safety hazard that causes because of the screw easy-to-rust.The grafting sheathing of using at present all is rigidity grafting sheathings; Its objective is convenience, improve installation effectiveness, but rigidity grafting sheathing does not possess sealing effectiveness in order to install; Moisture is easy to get into from the slit between path tubing and the rigidity grafting sheathing in wet environment; Make the end cut of path tubing be prone to produce corrosion, rust water may overflow (if open in grafting sheathing bottom Kong Ze have rust water flow out from the two ends of large-diameter pipe material) from the grafting sheathing, thus the clean and tidy and outward appearance that influences guardrail, protects window; Even also can cause connection to lose efficacy, stay potential safety hazard; If the rigidity sheathing of pegging graft is replaced by the resilient sleeve that elastomeric material processes and then can be improved sealing effectiveness; The end cut that prevents diameter pipes produces corrosion; But resilient sleeve can cause the installation resistance excessive with the contacting of perforate of large-diameter pipe material when mounted; Make installation effectiveness low, the elastomeric material cost is high, is unfavorable for applying.
Summary of the invention
The technical problem that the present invention will solve is the deficiency that overcomes prior art, and a kind of easy for installation, good airproof performance, the anti-water cutting grafting sealing shroud that is used for tubing simple in structure, with low cost are provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of anti-water cutting grafting sealing shroud that is used for tubing; Comprise and can an end be inserted in the rigid enclosure in the perforate of large-diameter pipe material; The said rigid enclosure other end offer can with the jack of path tubing socket, the edge that said rigidity is placed in jack openings is provided with the elastic seal ring that can closely contact with path tubing periphery.
The end face that said rigid enclosure and elastic seal ring join is provided with a circle raised step along the edge of jack openings, and said elastic seal ring is provided with the recess that cooperates with said raised step.
The end face that said rigid enclosure and elastic seal ring join is provided with a circle groove along the edge of jack openings, and said elastic seal ring is provided with the boss with said groove fit.
The periphery of said elastic seal ring is provided with the water conservancy diversion inclined-plane.
The outer peripheral face of said rigid enclosure be provided with a circle can with the draw-in groove of the edge clamping of large-diameter pipe material perforate.
Said draw-in groove is provided with guiding surface away from a side of elastic seal ring.
Compared with prior art, the invention has the advantages that:
The anti-water cutting grafting sealing shroud that is used for tubing of the present invention; Be provided with the elastic seal ring that can closely contact with path tubing periphery at the edge that rigidity is placed in jack openings; Through elastic seal ring the slit between rigid enclosure and the path tubing is sealed, can prevent that moisture from getting in the rigid enclosure, avoid the port of path tubing to produce corrosion; Make guardrail, protect the clean and tidy outward appearance of window maintenance, stopped the potential safety hazard that causes because of corrosion fully; Simultaneously,, can not contact, can not cause any harmful effect installation with the verge of opening of large-diameter pipe material because elastic seal ring is located at the edge of jack openings on the rigid enclosure, easy for installation, be easy to guarantee efficient installation.The present invention also can be provided with a circle raised step along the edge of jack openings at rigid enclosure and elastic seal ring and the end face that joins; And on elastic seal ring, be provided with the recess that cooperates with raised step; Cooperation through the two forms labyrinth seal structure; Can prevent that moisture from getting into rigid enclosure from the slit between elastic seal ring and the rigid enclosure, seal more reliable.The periphery of elastic seal ring is provided with the water conservancy diversion inclined-plane, be used for the water droplet that falls along path tubing timely water conservancy diversion go out the engagement edge of elastic seal ring and path tubing, prevent moisture penetration.

The specific embodiment
Fig. 1 to Fig. 3 shows a kind of anti-water cutting grafting sealing shroud embodiment that is used for tubing of the present invention; This grafting sealing shroud comprises and can an end be inserted in the rigid enclosure 1 in 3 perforates of large-diameter pipe material; Rigid enclosure 1 other end offer can with the jack 11 of path tubing 4 sockets, rigid enclosure 1 is provided with the elastic seal rings 2 that can closely contact with path tubing 4 periphery in the edge of jack 11 openings, seal through the slit between 2 pairs of rigid enclosure 1 of elastic seal ring and the path tubing 4; Can prevent that moisture from getting in the rigid enclosure 1; Avoid the port of path tubing 4 to produce corrosion, make guardrail, protect the clean and tidy outward appearance of window maintenance, stopped the potential safety hazard that causes because of corrosion fully; Simultaneously,, can not contact, can not cause any harmful effect installation with the verge of opening of large-diameter pipe material 3 because elastic seal ring 2 is located at the edge of jack 11 openings on the rigid enclosure 1, easy for installation, be easy to guarantee efficient installation.
In the present embodiment; The end face that further joins at rigid enclosure 1 and elastic seal ring 2 is provided with a circle raised step 12 along the edge of jack 11 openings; Elastic seal ring 2 is provided with the recess 21 that cooperates with raised step 12; Cooperation through the two forms labyrinth seal structure, can prevent that moisture from getting into rigid enclosure 1 from the slit between elastic seal ring 2 and the rigid enclosure 1, seal more reliable.The periphery of elastic seal ring 2 is provided with water conservancy diversion inclined-plane 23, be used for the water droplet that falls along path tubing 4 timely water conservancy diversion go out the engagement edge of elastic seal ring 2 and path tubing 4, prevent moisture penetration.
