Abstract
The utility model discloses a direct loose joint. The direct loose joint comprises a straight tube, wherein one end of the straight tube is connected with a stainless steel tube in an injection moulding manner; outward turned-over edges are arranged at the two ends of the stainless steel tube; the circumference of the stainless steel tube body between the two turned-over edges is sleeved with a nut. According to the utility model, one of the two turned-over edges at the two ends of the stainless steel tube is connected with the straight tube in an injection moulding manner to prevent the technical defect that the stainless steel tube and the straight tube are loosened, the other turned-over edge, together with the outer end part of the straight tube, axially limits the movement range of the nut to ensure that the nut can rotate around the circumference of the stainless steel tube, and accordingly, the technical purpose of movable connection is achieved.
Description
Technical field
The utility model relates to a kind of pipe connector lug, specifically a kind of direct-type loose joint joint.
Background technique
Joint is widely used in pipeline, all kinds of body connection function at present.Its structure of traditional joint is mostly metal or the moulding of plastics integrally casting, mainly exist be easily corroded, get rusty, the technological deficiency such as joint easily leaks.Certainly at present also exist some composite-joints and be mainly used in the connection of plastic pipe, there are the technological merits such as anticorrosive property is strong, easy to connect, but composite-joint is owing to being that the material of two kinds of materials connects, along with the variation of the serviceability temperature less technological deficiency of flow in the leak of liquid fault that causes and pipeline that tends to occur to become flexible in joint, comes off.How to prevent that the soundness of leaking and connecting from appearring in composite-joint, improving the working life of composite-joint and expanding composite-joint pipeline flow is the object that those skilled in the art study always.
Summary of the invention
The utility model provides a kind of flow, stable connection, direct-type loose joint joint easy to use of expanding.
A kind of direct-type loose joint joint, comprises straight tube, and described straight tube one end injection moulding is connected with Stainless Steel Tube, and Stainless Steel Tube two ends are equipped with outside flange, and the Stainless Steel Tube body periphery cover between two flange has nut.This kind of loose joint joint is by the turnup structure at Stainless Steel Tube two ends, connect straight tube by a flange injection moulding and prevent that the technological deficiency getting loose from appearring in Stainless Steel Tube and straight tube, and another flange carries out axial restraint in conjunction with the outer end of straight tube by the range of movement of nut, guarantee that nut can be rotated around Stainless Steel Tube circumference, realize the technical purpose being flexibly connected.
Described straight tube and Stainless Steel Tube connecting end, periphery is provided with the protruding tread plate of integrated injection molding, tread plate is uniformly distributed around straight tube periphery, tread plate structure be for after nut activity in joint connection procedure, particularly screw and in process, prevent that straight tube from moving and affect screwing that nut connects.Be provided with inside arc-shaped recess as the preferred tread plate of structure, the finger cambered surface of human body that this kind caved in favourable laminating, increases the travelling comfort operating.
Described straight tube is by the plastic tube and the mutual integrated injection molding of hole enlargement plastic tube that are positioned on same axis, the outer tube wall diameter of described plastic tube is identical with the diameter of bore of hole enlargement plastic tube, between plastic tube and hole enlargement plastic tube, is connected by conical surface.This kind of straight tube structure is identical with the diameter of bore of hole enlargement plastic tube by the outer tube wall diameter of plastic tube, in increasing pipeline flow, because the outer diameter of plastic tube is same as the connecting tube that will connect hole enlargement plastic tube, improved greatly aesthetics and the conformity of whole pipe-line system, and conical surface connects the problem of stress concentration of having avoided direct connection to cause.
The utility model is by the turnup structure at Stainless Steel Tube two ends, connect straight tube by a flange injection moulding and prevent that the technological deficiency getting loose from appearring in Stainless Steel Tube and straight tube, and another flange carries out axial restraint in conjunction with the outer end of straight tube by the range of movement of nut, guarantee that nut can be rotated around Stainless Steel Tube circumference, realize the technical purpose being flexibly connected.
Brief description of the drawings
Be illustrated in figure 1 the utility model direct-type loose joint joint perspective view.
