Embodiment

[0023] as attached figure 1 to attach Image 6 Shown:

[0024] The invention provides a quick-plug connector with a new combination structure, which includes a body (1), and four hanging platforms (11) are sequentially arranged inside the body (1), and a compression sleeve (6) is pressed into the body (1) from the head. ), the hanging platform (11) fits into the annular groove (61) to complete the compression connection, and the first step hole (12), the second step hole (13), and the third step hole (14) are in sequence Below (11), there are fixed rings (4), Y-shaped sealing rings (3), and guide rods (2), respectively. The fixed rings (4) are pressed and fixed by the compression sleeve (6) after being pressed, The snap ring (5) is freely installed on the fixed ring (4), and its inner cone surface (55) is in contact with the upper cone surface (42) of the fixed ring. When working, its outer cone surface (57) is in contact with the inner cone surface of the compression sleeve...

Abstract

The invention provides a quick-plug connector of a novel combined structure. The quick-plug connector comprises a body, a guide rod, a Y-shaped sealing ring, a fixing ring, a clamping ring, a pressingsleeve, and a threaded connector assembly. A hanging table, a stepped hole and a clamping jaw are sequentially arranged inside the structure of the body. A reinforcing rib and an annular boss are sequentially arranged outside the body. The pressing sleeve is matched with the hanging table inside the body in an embedded mode; the clamping ring plays a locking role when a nylon pipe is inserted; the upper end of the fixing ring is pressed by the pressing sleeve; the Y-shaped sealing ring plays a sealing role when the nylon pipe is inserted; the guide rod plays a role in guiding when the nylon pipe is inserted; a dustproof ring is assembled at the boss outside the body; and the threaded connector assembly is assembled at a clamping jaw end and makes contact with the dustproof ring, so that the function of connecting with an installation end is achieved, and the rotating function of the quick-plug connector can be achieved. Compared with the prior art, the quick-plug connector of the novel combined structure has the characteristics of being capable of freely rotating at any angle, good in sealing performance, suitable for different working conditions in different environments and thelike.

Description

technical field [0001] The invention belongs to the technical field of connecting components, and provides a quick pipe joint for connecting flexible pipes, in particular to a quick-plug joint with a novel combined structure. Background technique [0002] Nylon tube has wear resistance, tensile and bending properties, great stability, and is easy to install. Its good comprehensive performance is unmatched by copper tube, steel tube and rubber tube. It is an ideal material to replace copper, steel and rubber. , and in the use of nylon tubes, it is usually necessary to connect and convert nylon tubes through push-in connectors. [0003] However, the cannula end and the threaded end of the existing push-in connector generally cannot rotate freely, and the operation is inconvenient. At the same time, the existing push-in connector generally adopts a connection method in which barbs are inserted into the resin body for internal connection, which is limited by the strength of the ...
