Abstract
The utility model relates to a bayonet plastic conduit connector, the connector includes the plastic tubing of an internal diameter along the axial invariant, it is protruding that plastic tubing surface middle part is equipped with a week waist drum form, and the left and right sides of plastic tubing surface all is equipped with corrugated the ending of round and passes through the rack, end passing through the rack and all installing on the plastic tubing through elastic connection's mode, end and pass through the rack and all be equipped with the round under and offer the sunken slot on the plastic tubing lateral surface, sunken ditch inslot all is equipped with the sealing washer. The utility model discloses the utilization is established and is passed through the rack ending of plastic tubing both ends and carry out the high -speed joint, and ends and pass through the rack and receive pipe inner wall and connect the outer wall extrusion, under the elastic reaction, end and pass through all press the sealing circles downwards of rack, the pipeline with connect between the space along with obtaining closely knit packing, it is convenient to connect, anti penetration leaks effectually.
Description
Technical field
The utility model relates to connecting tube equipment technical field, is that one is suitable for inwall positive round specifically, and axially straight, any material pipeline connection joint of outer wall arbitrary shape, i.e. a kind of plug-in type plastic pipeline joint.
Background technique
Current municipal drainage blowdown, Sewage treatment, rainwater-collecting all have employed has good pipeclay effect, and ring stiffness is higher, the anticorrosion aging-resistant plastic pipe that tensile strength is stronger.These pipelines have a common ground to be exactly that inwall is axially straight, and shortcoming is that outer wall is different, the tubing of same specification, and external diameter difference is very large.Existing tube connection piece intercommunity is poor, installs, and safeguards that replacing is very inconvenient.
Existing pipeline connects, and is summed up and can be divided into following four kinds:
1, hot-melt extruded be welded to connect should by special extrude soldering appliance and extrude welding rod adjacent pipe end is heated, make its polythene material melting journey overall, shortcoming: (1) heating needs power supply, there is ponding at site construction scene more, equipment, personnel activity is frequent, there is potential safety hazard during construction; (2): jointing will ensure absolute cleanliness, a dust can have, and this is difficult to accomplish for the building site of a field construction; (3): this welding belongs to rigid connection method, require tighter to the backfill of pipeline soil stone.
2, electric melting connection, comprises that electric smelting band is external to be connected with the electric smelting of taper spigot and socket type.Be by being embedded in the electric network heating of electric smelting band internal surface or heating electric network in taper joint socket, make the polyethylene layer between electric smelting band and tubing trough melt for entirety, belong to rigid connection method.Shortcoming is welded with hot-melt extruded.
3, heat-shrinkable tube (band) connection should by carrying out flame heating to heat-shrinkable tube (band), and the hot melt adhesive making it shrink cover internal surface is bonding with pipe outer surface integral; Heat-shrinkable tube (band) cooling curing forms constant package power, belongs to rigid connection method equally.Except not needing power supply, other shortcoming is the same with hot-melt extruded welding.
4, clip connected clamps two semicircle outer sleeves by bolt, thus make adjacent pipe end fastening, and adopt the rubber pad between sleeve and tube wall to reach seal request, belongs to rigid connection method.Shortcoming is clip, and bolt is owing to being fabricated metals, and anti-corrosion capability is limited.Particularly clip, because too thin, once corrosion, sealability will weaken greatly; Therefore, be necessary to provide a kind of for plastic pipe jointing, fundamentally overcome on above-mentioned construction process and pipe joint structure and there is various shortcoming.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of plug-in type plastic pipeline joint.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of plug-in type plastic pipeline joint, described connecting head comprises internal diameter plastic tube constant vertically, one week waist drum shape projection is provided with in the middle part of described plastic tube outer surface, the left and right sides of plastic tube outer surface is equipped with the corrugated only saturating tooth bar of a circle, the described only mode that saturating tooth bar is all connected by elasticity is installed on the plastic tube, only be equipped with a circle immediately below saturating tooth bar and be opened in recessed trench on plastic tube outer side surface, described only saturating tooth bar bottom is also fixed with the convex button pin coordinated with recessed trench, to prevent from being subjected to displacement when only saturating tooth bar is installed.
The beneficial effects of the utility model are: the utility model utilizes the only saturating tooth bar being located at plastic tube two ends to connect fast, and only saturating tooth bar is subject to inner-walls of duct and the extruding of joint outer wall, under elastic reaction, only saturating tooth bar press seal circle all downwards, between pipeline and joint, space is with obtaining dense packing effect, easy to connect, anti-divulge effective.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is internal structure schematic diagram of the present utility model.
Embodiment
In order to make the utility model technological means and creation characteristic be easy to understand, below the utility model is set forth further.
As shown in Figure 1, a kind of plug-in type plastic pipeline joint, described connecting head comprises internal diameter plastic tube constant vertically 1, one week waist drum shape projection is provided with in the middle part of described plastic tube 1 outer surface, the left and right sides of plastic tube 1 outer surface is equipped with the corrugated only saturating tooth bar 2 of a circle, the described only mode that saturating tooth bar 2 is all connected by elasticity is arranged on plastic tube 1, only be equipped with a circle immediately below saturating tooth bar 2 and be opened in recessed trench 3 on plastic tube 1 outer side surface, described only saturating tooth bar 2 bottom is also fixed with the convex button pin 4 coordinated with recessed trench 3, to prevent from being subjected to displacement when only saturating tooth bar 2 is installed.
During use, under the pressure of external inner-walls of duct, there is elastic strain downwards in the corrugated only saturating tooth bar coordinated with inner-walls of duct, because the mode that only saturating tooth bar is all connected by elasticity is installed on the plastic tube, only saturating tooth bar compression yardstick can be expanded further, by the seal ring that is positioned at below only saturating tooth bar tightly compacting on the plastic tube, thus realize sealing when pipeline connects.Described waist drum shape projection can smear the materials such as anti-seep through, can secondary seal be served as in use, improve connection sealing further.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
