Abstract
The utility model discloses a handy pipe joint. An adjusting hole is arranged at the middle section of a pipe-shaped inner chamber of a pipe joint, and the end parts of the pipe-shaped inner chamber of a pipe joint are provided with connecting holes, wherein, the diameters of the connecting holes are bigger than the diameter of the adjusting hole and inner threads are arranged on the inner walls of the connecting holes. The connecting surfaces among the adjusting hole and the connecting holes are provided with sealing clamp expansion rings, and pipe-shaped fastening pipe fittings are respectively arranged in the connecting holes of the ends of the pipe joint, wherein, the pipe-shaped fastening pipe fittings are in the thread fit with the connecting holes and the inner diameters of the pipe-shaped fastening pipe fittings are equal to the diameter of the adjusting hole. The utility model has the characteristics of normative installation, shapely appearance, time saving, labor saving and convenient maintenance and replacement.
Description
The utility model relates to a kind of pipe that is used for the pipeline connection and connects, and is specially a kind of nimble pipe and connects.
At present, known pipe connects, no matter be that straight connector connects, still the bend pipe connecting tube connects, all adopt the connecting end that connects at pipe that female scheme is set, during use, the outside thread that need match at the internal thread that connecting end is processed with pipe connects of coupled pipe fitting links together adjacent two pipe fittings by screw-thread fit.Though the pipe of this structure connects the task that adjacent two pipe fittings is linked together of realizing, but it in use needs machining screw on connected pipe fitting, and when screw-thread fit connects, need add the sealing affix and can realize the task of being tightly connected, therefore use effort time-consuming, lack of standardization by adorning, not attractive in appearance, be not easy to the unsurmountable defective that maintain and replace is its existence.
The purpose of this utility model provides a kind of nimble pipe and connects, and it not only has uses laborsaving saving time, and installation specification is attractive in appearance and have the advantages that to be convenient to maintain and replace.
The purpose of this utility model is achieved in that connecing the inner chamber intermediate section at tubular pipe is provided with and the isodiametric adjustment hole of connecting tube cylindrical, tubular pipe connect each end of inner chamber be provided with its diameter greater than the diameter of adjustment hole and within it wall be provided with the attachment hole of internal thread, the elongation line of the junction surface between adjustment hole and the attachment hole is 25 °-45 ° angle with respect to the angle α of adjustment hole inwall, be provided with sealing chucking piston ring respectively at the junction surface place of each adjustment hole and attachment hole formation, the interior circular diameter of sealing chucking piston ring and the equal diameters of adjustment hole, the equal diameters of its outside diameter and attachment hole, the elongation line of its both ends of the surface is 25 °-45 ° angle with respect to the angle α of its inner headed face, is respectively arranged with its internal diameter of its screw-internal thread fit in pipe connects the attachment hole of each end and its adjustment hole is isodiametric and the elongation line of its end face is that α is the tubular fastening pipe fitting at 25 °-45 ° angle with respect to the angle of inwall.Owing to adopted such scheme to enter after pipe connects in the adjustment hole when connecting tube tightens piston ring by fastening pipe fitting and sealing, by the fastening pipe fitting of precession sealing chucking piston ring is exerted pressure, sealing chucking piston ring pressurized is risen outward, connecting tube is produced a pressure, thus the task that realization is tightly connected.Simultaneously because the scheme that has adopted sealing chucking piston ring pressure to connect so realized installation specification, attractive in appearance, time saving and energy saving, is convenient to the task of maintain and replace.
That the utility model is described in further detail is as follows below in conjunction with drawings and Examples.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 3 is structural representations of the sealing chucking piston ring in the accompanying drawing 1;
Accompanying drawing 4 is structural representations of the fastening pipe fitting in the accompanying drawing 1.
