Abstract
The utility model discloses a movable connector assembly. The movable connector assembly comprises a connector body, a union nut, a sealing gasket and a fast-connecting end. The threaded portion of the union nut is matched with outer threads of the fast-connecting end. The connector body is matched with an inner hole of the union nut. The inner hole of the union nut is arranged in the connector body in an inclined mode. The sealing gasket is arranged on the end face of the connector body and located between the connector body and the fast-connecting end. According to the movable connector assembly, a connector is in fast loose joint with the fast-connecting end, so that production efficiency is improved, production cost is reduced, and reliability of a product is improved.
Description
Technical field
The utility model relates to pipe transportation technology, relates in particular to pipe joint, particularly a kind of movable joint assembly of realizing two Split type structures connections easy to use simple in structure.
Background technique
The connection of two Split type structures in prior art, adopts Female connector fittings first to pack welded structure or the Snap ring structure of adapter into.Female connector fittings first packs the welded structure of adapter into: loose joint nut is packed in adapter, take over and have step, then will take over and insert in valve body joint, carry out soldering; Then carry out the assembling of valve, finally rubber pad is fitted with the step end face place in taking over.The shortcoming existing is Product Assembly complexity, loose joint nut need to be packed into, during due to welding, will produce higher temperature, and loose joint nut will be out of shape, and exists the outside thread coordinating with it to coordinate the phenomenon of not entering, and causes product rejection.Another is Snap ring structure, takes over and valve body one, and there is an annular groove at the step place of adapter, and loose joint nut is packed in adapter, then loads onto outer snap ring, finally rubber pad is fitted with the step end face place in taking over.The shortcoming existing is owing to being snap ring, so corresponding cooperation place needs higher precision, otherwise the phenomenon that easily causes loose joint nut and valve body to come off, poor reliability.Owing to there being snap ring, assembling is complicated.
Summary of the invention
The purpose of this utility model 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 problems to be solved in the utility model 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 the moulding of forging and stamping mode.
Working principle of the present utility model is to be greater than the large footpath of fittings body because the internal diameter of loose joint nut has part, so in the time that loose joint nut is tiltedly put, be equivalent to path place and also become large.As long as there is rational size, just can realizes whole of loose joint nut and put in fittings body.When loose joint nut is with after fast the outside thread of end coordinates, ensure the coaxial of loose joint nut and fittings body and quick connection port, because the path of loose joint nut is less than the large footpath of fittings body, realize loose joint nut and be connected with the reliable of fittings body and quick connection port.
The utility model compared with prior art tool has the following advantages: compared with the welded structure that 1, first packs adapter into Female connector fittings, it is convenient that assembling adds man-hour, there is no the impact of loose joint nut in when welding, and the high temperature producing when welding can not make nut distortion yet, thereby reduce scrappage.2, compared with Snap ring structure, reduce snap ring, save material, having avoided snap ring to install needs higher machining accuracy, has improved the reliability of product.3, the utility model 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, has realized connecting head and has held and be connected fast in the mode of loose joint fast.Improve manufacturing efficiency, reduced cost of production, and promoted the reliability of product.
