Abstract
The utility model relates to a plastic pipeline connecting joint, comprising a pipeline upper joint and a pipeline lower joint. The pipeline upper joint and the pipeline lower joint are arranged on the same cylindrical shaft center and are mutually connected; a circular flange which is vertical to the cylindrical shaft center is arranged between the pipeline upper joint and the pipeline lower joint along the outer surface of the plastic pipeline connecting joint; the outer surface of the pipeline lower joint is fixedly connected with the inner surface of a pressing sleeve in a threaded manner; the pressing sleeve is meshed with a switching pipe socket, and the switching pipe socket is compressed to the lower end of the pipeline lower joint; the pipeline lower joint, the pressing sleeve and the switching pipe socket share one cylindrical shaft center; and more than two through holes are uniformly distributed on the circular flange along the circle of the flange. The plastic pipeline connecting joint not only can realize the connection of pipelines at the two ends, but also can realize the connection in branch pipeline mode. The plastic pipeline connecting joint is simple, flexible, convenient and applicable.
Description
Technical field
The utility model relates to the installing area of pipeline, particularly a kind of plastic cement bonded joint.
Technical background
The connection of plastic cement pipeline generally has adhesive connection, flange connection etc. in the prior art.But when concrete the installation, the connection interface place often relates to the pipeline of distinct interface, prior art head it off underaction.In general, realize the jointing that the two ends pipeline connects, can not realize the jointing of lateral pattern simultaneously.In addition at the jointing of lateral pattern, or can only realize that adhesive connects, or can only realize that flange connects, the restriction in this use has increased the complexity that plastic pipe connects.
The model utility content
The purpose of this utility model is exactly at above-mentioned deficiency, designs a kind of jointing that can realize that the two ends pipeline connects, can realize a kind of plastic cement pipe connector lug of the connection of lateral pattern again.Its simple and flexible, convenient being suitable for.
In order to solve the problems of the technologies described above, the utility model comprises following technological scheme: a kind of plastic cement pipe connector lug, comprise interconnective in the heart pipeline upper connection of same cylinder axis and pipeline lower contact, between pipeline upper connection and the pipeline lower contact, perpendicular to the cylindrical body axle center, be connected with a ring bead along described plastic cement pipe connector lug outer surface; Described pipeline lower contact outer surface is connected with the gland internal surface; Described gland is meshed with a switching bellmouth, the switching bellmouth is pressed to the lower end of pipeline lower contact; Described pipeline lower contact, gland and switching bellmouth have same cylinder axle center.
The pvc material that described pipeline upper connection, pipeline lower contact, bead are one of the forming.
Described pipeline lower contact outer surface is that screw thread is fixedlyed connected with the gland internal surface.
Be provided with seal ring between described switching bellmouth upper end and the pipeline lower contact lower end.
Described bead upper edge bead circumference is evenly distributed with two above through holes.
Described bead is provided with sealing gasket; Described sealing gasket is provided with the pilot hole that matches with through hole.
Be equipped with double-screw bolt in described through hole and the pilot hole, the other end of double-screw bolt is connected with nut.
Compared with prior art, the beneficial effects of the utility model are: at first, the ring bead realized can two ends pipeline connect the function that again can branching pattern connects.When the two ends pipeline connected, this ring bead played location and position-limiting action to up-hill line; When branching pattern connected, the ring bead played the effect of connection.User's directly perforate on main pipe as required, bead both can be connected with main pipe by adhesive, also can connect by the flange ways of connecting, made things convenient for the user to change piping erection according to actual needs at any time.Secondly, described pipeline lower contact outer surface thread is fixedly connected with gland; Described gland is meshed with a switching bellmouth, the switching bellmouth is pressed to the lower end of pipeline lower contact.The pipeline of threaded coupling and the connectivity problem of no screw thread joint pipeline had so both been solved, when being applied to the branching pattern connection, under the situation that no longer needs certain pipe branch, can be at any time as required, with supporting screw plug shutoff interface, when treating new the needs, can open shutoff, pipe laying again.Described inipple connects applicable to the pipeline of various material, and is easy for installation, and can satisfy at any time needs are installed.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural drawing;
Fig. 2 is the utility model embodiment 2 a structural drawing.
Embodiment
The utility model embodiment 1 structure as shown in Figure 1, a kind of plastic cement pipe connector lug, comprise interconnective in the heart pipeline upper connection 1 of same cylinder axis and pipeline lower contact 2, between pipeline upper connection 1 and the pipeline lower contact 2, perpendicular to the cylindrical body axle center, be connected with a ring bead 3 along described plastic cement pipe connector lug outer surface.
Described pipeline lower contact 2 outer surfaces are fixedlyed connected with gland 4 internal surface screw threads; Described gland 4 is meshed with a switching bellmouth 5, switching bellmouth 5 is pressed to the lower end of pipeline lower contact 2; Described pipeline lower contact 2, gland 4 have same cylinder axle center with switching bellmouth 5.The design that pipeline lower contact 2 outer surfaces are fixedlyed connected with gland 4 internal surface screw threads, purpose is for when pipe ends connects, and solves the pipeline of threaded coupling and the connectivity problem of no screw thread joint pipeline; When branching pattern connects, can be under the situation that no longer needs certain pipe branch, can be at any time as required, with supporting screw plug shutoff interface, when treating new the needs, can open shutoff, pipe laying again.
For convenient for production, the pvc material that described pipeline upper connection 1, pipeline lower contact 2, bead 3 are one of the forming.
When pipe ends connected, the inner surface diameter of up-hill line equaled pipeline upper connection 1 outer surface diameter, and up-hill line is inserted in the surperficial and bonding of pipeline upper connection 1, and described ring bead 3 plays up-hill line location and position-limiting action.Pipeline lower contact 2 outer surfaces are fixedlyed connected with gland 4 internal surface screw threads, and are meshed with switching bellmouth 5 by gland 4, and switching bellmouth 5 is pressed to the lower end of pipeline lower contact 2, and switching bellmouth 5 is connected with descending pipeline by adhesive.
When the connection of lateral pattern, ring bead 3 plays the effect of connection.The user can be in needs directly perforate on main pipe, bead 3 is connected with main pipe by adhesive, pipeline lower contact 2 outer surfaces are fixedlyed connected with gland 4 internal surface screw threads, be meshed with switching bellmouth 5 by gland 4, switching bellmouth 5 is pressed to the lower end of pipeline lower contact 2, and switching bellmouth 5 is connected with descending pipeline by adhesive.
