Problems solved by technology

If this chamfer is missing or insufficient, there is the danger that the sealing ring abutting against the end face of the plastic pipe will be squeezed out of the groove and along the connection The joint moves, which again compromises the necessary seal between the connection joint and the plastic tube, and this damage cannot be detected because the clamping sleeve covers the sealing ring, wherein the plastic tube is inserted between the clamping sleeve and the connection joint

Embodiment Construction

[0016] The device for connecting a plastic pipe 1 to a connecting joint 2 of an accessory not shown in detail has a clamping sleeve 3 between which the connecting end 4 of the plastic pipe 1 is inserted so as to be subsequently clamped The sleeve 3 is fixedly clamped on the formed connecting joint 2 , for example by pressing in a circumferential bead. The sealing between the connecting piece 2 and the connecting end 4 of the plastic pipe 1 is achieved by means of two sealing rings 5 ​​placed in the annular groove 6 of the connecting piece 2 . like figure 1 and figure 2 It can be seen that in order to prevent the sealing ring 5 protruding from the outer circumference of the connecting joint 2 in the unloaded state from being squeezed from the groove 6 when the end 4 of the plastic pipe 1 is inserted into the annular gap between the connecting joint 2 and the clamping sleeve 3 Note that the end face 7 of the connection end 4 of the plastic tube 1 is provided with a chamfer 8 ...

Abstract

The invention relates to a device for connecting a plastic tube (1) to a connection nipple (2). The connection end (4) of the plastic tube (1), provided with a front-side chamfered element (8) in the region of the inner diameter, is axially fixed between the connection nipple (2) and a clamping sleeve (3) by the insertion of at least one sealing ring (5) held in the profiled connection nipple (2). In order to create advantageous connection conditions, the connection nipple (2) has at least one radially outwardly projecting abutment that can be moved radially inwardly by means of the front-side chamfered element (8) in the region of the inner diameter of the connection end (4), the abutment (14) being arranged upstream of the sealing ring (5) in the insertion direction.

Description

technical field [0001] The invention relates to a device for connecting plastic pipes to connection fittings, wherein the connection ends of the plastic pipes, which are provided with end-side chamfers in the range of the inner diameter, are provided with at least one clamping-shaped connection connection in the middle. The upper sealing ring is clamped axially between the connection joint and the clamping sleeve. Background technique [0002] In order to secure a plastic pipe loaded with a pressure medium, such as a pipe for water conduction in the field of household appliances, to the connection joint of the fitting in a manner that prevents extraction, it is known to place a sliding sleeve on a molded part The plastic tube on the connecting piece is firmly clamped between the connecting piece and the clamping sleeve surrounding the plastic tube. In this case, the sealing between the connecting piece and the plastic pipe is ensured by at least one sealing ring inserted in...
