Abstract
The invention discloses a rapid plastic pipe connector structure. The rapid plastic pipe connector structure comprises connector bodies which are horizontally symmetrical. Each connector body is composed of a connection section and an end cover installation section. A first step face, a second step face, a third step face and a fourth step face are sequentially arranged in each connector body. A pipe detachment device is arranged in each end cover installation section. A locking cover is arranged between each pipe detachment device and the corresponding end cover installation section. Each locking cover is fixedly connected with the inner wall of the corresponding end cover installation section. The tail end of each locking cover only abuts against the corresponding first step face. A sleeve is arranged between each second step face and the corresponding locking cover. An elastic piece is fixed between each sleeve and the tail end of the corresponding locking cover. A seal ring is arranged between each sleeve and the corresponding third step face. Due to the adoption of the pipe connector structure, the installation process of a pipe fitting is rapid, and time and labor are saved in the installation process; in the maintaining process, the rapid plastic pipe connector structure can be detached by directly opening the locking covers without being influenced by the installation space, and therefore the dual-insurance effect is achieved.
Description
Technical field
The invention belongs to technical field of pipeline connection, specifically relate to a kind of fast-assembling plastic pipe joint header structure.
Background technique
Along with the development in domestic hot-water heating market, its tubular type is varied, and the Placement of pipe pipe fitting is also tending towards variation, and current modal pipe Placement is direct insertion; But in this Placement, usually there will be pipe insert after due to factors such as space, place are wide not, pipe is excessive, causing taking the very large power of Shi Yaoyong apart just can take apart, even tears open not open, and dismounting is wasted time and energy.Such as, publication number is that the Chinese patent of CN 202371363 U discloses the two binding ring locking arrangement of a kind of Quick-insertion type pipe joint, improve the quick connection of pipe fitting, special seal arrangement has been installed, the free loading, unloading pipe fitting of discharging pipe device energy installed, interior jump ring in movable jump ring and discharging pipe device has the effect of double locking pipe fitting, not fragile in the process that user uses.But because this locking mechanism only adopts a pipe fitting, when therefore using in the aqueduct that pressure is larger, easily produce obscission, the effect of dual fail-safe can not be arrived.Because this structure adopts V-shaped seal ring, therefore, sealing effect is unstable, and when especially pressure is large, seal ring inner ring is difficult to make to be effective together with seal ring and pipe combination just under the effect of hydraulic pressure.

For solving the problems of the technologies described above, the invention provides a kind of fast-assembling plastic pipe joint header structure.
The present invention is achieved by following technical solution.
A kind of fast-assembling plastic pipe joint header structure, comprise symmetrical fittings body, described fittings body is made up of linkage section and end cap construction section, First terrace is disposed with in fittings body inside, second step face, 3rd step surface and the 4th step surface, in described end cap construction section, discharging pipe device is installed, tightening cover is provided with between discharging pipe device and end cap construction section, described tightening cover connects with end cap construction section inner wall tightening, and tightening cover end is only by First terrace, sleeve pipe is provided with between described second step face and tightening cover, shell fragment is fixed with between sleeve pipe and tightening cover end.
Also seal ring is provided with between described sleeve pipe and the 3rd step surface.
Institute's tightening cover is made up of cylindrical section and thread section, and wherein, thread section is connected with the internal thread be arranged at inside end cap construction section by outside thread.
Described discharging pipe device is made up of end plate and screw-in section, screw-in section is provided with chamfering away from end plate one end, and within one week, has been evenly arranged some projections along chamfering.
Described shell fragment is made up of ring segment and elastomer block, and wherein, elastomer block is evenly arranged on ring segment, and outward-dipping, and the chamfering on this angle of inclination and discharging pipe device matches.
The external cylindrical surface of described cylindrical shell of column adopts polygon structure.
Described sleeve pipe is the boss type structure be made up of plastics, and the upper end of sleeve pipe is near second step face, and lower end surface contacts with seal ring.
Described seal ring is bowl-type rubber seal.
Described end cap construction section is connected by plane of inclination with between linkage section.
The angle of described plane of inclination and horizontal plane is 45 °.
The invention has the beneficial effects as follows:
Compared with prior art, the present invention, by arranging symmetrical fittings body, is simultaneously provided with discharging pipe device and tightening cover in fittings body end, make pipe fitting quick in installation process, save time, laborsaving.After pipe pipe fitting connects, due to a variety of causes must pull down and reinstall time, directly can open tightening cover and just can remove, not by the impact of installing space, thus play the effect of dual fail-safe.Owing to adopting bowl-type rubber seal, this kind of seal ring sealing effect is highly stable, and when especially pressure is large, seal ring inner ring makes seal ring and pipe combine more closely under the effect of hydraulic pressure, thus reaches and better enclose sealing effect.
