Abstract
The invention discloses a movable joint component. The movable joint component comprises a joint body, a movable joint nut, a sealing gasket and a quick connecting end, wherein a thread of the movable joint nut fits an external thread of the quick connecting end; the joint body fits an inner hole of the movable joint nut; the inner hole of the movable joint nut is inclined into the joint body; and the sealing gasket is arranged on the end surface of the joint body, and is positioned between the joint body and the quick connecting end. The movable joint component realizes quick connection between the connecting head and the quick end in a movable connecting manner. The movable joint component improves the production efficiency, reduces the production cost, and enhances the product reliability.
Description
Technical field
The present invention relates to pipe transportation technology, particularly relate to pipe joint, what particularly a kind of structure was simply easy to use realize movable joint assembly that two Split type structures connect.
Background technique
The connection of two Split type structures in prior art, adopts Female connector fittings first to load welded structure or the Snap ring structure of adapter.Female connector fittings first loads the welded structure of adapter: loaded by loose joint nut in adapter, adapter has step, then adapter is inserted in valve body connector, carries out soldering; Then carry out the assembling of valve, finally rubber pad and the step end face place in adapter are fitted.The shortcoming existed is that Product Assembly is complicated, and need loose joint nut to load, will produce higher temperature due to during welding, loose joint nut will be out of shape, and there is the outside thread coordinated with it and coordinates the phenomenon of not entering, cause product rejection.Another is Snap ring structure, adapter and valve body, and there is an annular groove at the step place of adapter, is loaded in adapter by loose joint nut, then loads onto outer snap ring, finally rubber pad and the step end face place in adapter is fitted.The shortcoming existed is owing to being snap ring, so corresponding cooperation place needs higher precision, otherwise easily causes the phenomenon that loose joint nut and valve body come off, poor reliability.Owing to there being snap ring, assembling is complicated.
Summary of the invention
The object of this invention is to provide the movable joint assembly that a kind of fixing link is few, cost is low, product reliability is high.
The technological scheme that the technical problem to be solved in the present invention adopts is: movable joint assembly, comprise fittings body, loose joint nut, sealing gasket and quick connection port, the screw thread place of loose joint nut coordinates with the outside thread of quick connection port, fittings body coordinates with loose joint nut inner hole, loose joint nut inner hole is tiltedly inserted in fittings body, sealing gasket is located on the end face of fittings body, and between fittings body and quick connection port.

Described movable joint assembly, basic circular arc and the expansion circular arc of its composition loose joint nut inner hole adopt forging and stamping mode shaping.
Working principle of the present invention is because the internal diameter of loose joint nut has part to be greater than the large footpath of fittings body, so when loose joint nut is tiltedly put, is equivalent to path place and also becomes large.As long as there is rational size, just can realizes whole of loose joint nut and put in fittings body.After loose joint nut coordinates with the outside thread held fast, ensure that the coaxial of loose joint nut and fittings body and quick connection port, the path due to loose joint nut is less than the large footpath of fittings body, achieves loose joint nut and is connected with fittings body and the reliable of quick connection port.
The present invention compared with prior art tool has the following advantages: compared with the welded structure 1, first loading adapter with Female connector fittings, convenient during assembly manufacturing, there is no the impact of loose joint nut when welding, and the high temperature produced during welding also can not make nut be out of shape, thus reduce scrappage.2, compared with Snap ring structure, decrease snap ring, saved material, avoid snap ring and the higher machining accuracy of needs is installed, improve the reliability of product.3, the present invention utilizes loose joint nut to be directly inserted in the groove of connecting head, and the outside thread of end is connected with the internal thread of loose joint nut fast, achieves connecting head and is connected fast in the mode of loose joint with holding fast.Improve manufacturing efficiency, reduce cost of production, and improve the reliability of product.
