Embodiment 1

[0059] like figure 2 As shown, the pipe joint for quick connection of the present invention is composed of two axially butted connecting parts (I, II).

[0060] The connecting parts (I, II) have the same structure, are connected in opposite directions, and communicate with each other in the axial direction. Now take the connecting part (I) as an example.

[0061] The connection part (I) consists of the pipe joint main body 1 and the O-ring sealing ring 2 contained therein, the sealing ring pressing ring 3, the elastic ring gear 4 for locking the pipe body, the elastic ring ring pressing ring 5, the pipe snap ring 6 and the lock Stop ring 7 constitutes.

[0062] like figure 2 As shown in -5, the pipe joint main body 1 is a hollow cylindrical connector made of plastic. An annular stepped plane is formed on the inner wall near the central part, on which O-shaped sealing ring 2, sealing ring pressure ring 3, elastic gear ring 4 for pipe body locking, and elastic gear ring pr...

Embodiment 2

[0080] In addition to the outer side of the lower end of the locking ring 7, there are six symmetrical radially outwardly protruding buckle feet (protruding blocks), and six corresponding inner buckle grooves are formed on the corresponding inner wall side of the main body of the pipe joint. The angle of α 95-98°. In addition, the elastic ring ring 5 is not installed on the elastic ring gear 4, and the sealing ring ring, the elastic ring gear 4, and the elastic ring ring 5 do not form a three-in-one assembly. Other As in Example 1, a pipe joint for quick connection of the present invention was produced.

Embodiment 3

[0082] In addition to an axial groove on the inner wall of the main body of the pipe joint, a corresponding protrusion is also provided on the corresponding position of the elastic ring gear, and the included angle β is 80-82°. (5) The pipe joint for quick connection of the present invention is obtained as in Example 1 except that the pressing contact surface with the lower end plane of the anti-locking ring foot (9) forms an arc surface.

[0083] Accordingly, when the elastic ring gear is put into the main body of the pipe joint, the protrusion on the elastic ring gear is aligned with the groove on the inner wall of the main body of the pipe joint. In this way, the installed quick pipe joint can prevent relative axial rotation with the pipe due to the torque applied to the pipe or the quick joint.

Abstract

The invention relates to a pipe connector for quick connection. In the invention, a connecting part comprises an O-shaped sealing ring (2), a sealing ring pressing ring (3), a resilient gear ring (4), a pipe return snap ring (6) and a locking ring (7) which are sequentially contained in a pipe connector main body (1), wherein a plurality of reserved fastening legs (9) which are radially projectedoutwards are formed at the axial lower end of the locking ring (7), inner-concave fastening slots (10) corresponding to reversed fastening legs are formed at the inner wall of the pipe connector mainbody (1), a radial guide flow thin slot (11) is formed on the plane of the ring-shaped step for installing the O-shaped sealing ring, and the contact surfaces of the upper plane of the reserved legs (9) and the inner wall of the pipe connector main body (7) form angles alpha of 91-100 degrees. According to the invention, when the pipe connector is used for a long time, the use of the locking ring(7) should not happen loose and the sealing performance degradation in a long time. The pipe connector for quick connection can be quickly connected with pipes, and can be disassembled and assembled with the pipes, no energy consumption is needed for the connection, auxiliary tools and sealing packing are free, the larger the inner pressure is, the better the sealability is, the comprehensive connection cost is reduced, and the use is convenient.

Description

technical field [0001] The invention relates to a pipe joint for pipe connection, in particular, the invention relates to a pipe joint for quick connection used for quick butt joint of fluid conveying pipes such as water pipes. Background technique [0002] Pipelines are essential infrastructure for industry. The pipeline connection device is an indispensable means of connection. [0003] At present, the well-known pipeline connections mainly include threaded connections (metal pipes) and hot-melt connections (PP-R and PE pipes, etc.). The threaded connection is to use the internal and external threads of the joint and the pipe as the screw connection, and use white paint hemp silk or polytetrafluoroethylene raw material tape as the sealing packing to seal; the hot-melt connection is to use electric heating to connect the pipe and the joint to be connected. (End faces or connection contact surfaces) heated to a molten state, and then pressed against each other, so that the...
