Detailed Description

Embodiments of the technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.

It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this utility model belongs.

As shown in fig. 1-4, this embodiment provides a buckling member made outside a groove, including a buckling member body 100, the buckling member body 100 is a hollow pipe body, a first end of the buckling member body 100 is provided with a riveting inlet, a second end of the buckling member body 100 is provided with a tension clamping member, the periphery of the buckling member body 100 is provided with a plurality of extrusion bosses 110 arranged at intervals, a deformation groove 120 is defined between adjacent extrusion bosses 110, when the buckling member is connected and pressed, the inner wall of the buckling member body 100 is extruded with a plurality of fixing ribs 111 extending radially inwards, and the outer wall of the buckling member body 100 is extruded with deformation ribs 121 radially outwards corresponding to the positions of the deformation grooves 120.

During the use, will withhold a body 100 and wait to connect joint 300 and combine together for form fixed space between the outer wall that withhold a body 100 and wait to connect joint 300, the extrusion boss 110 that sets up and deformation groove 120 interval setting can guarantee to withhold a body 100 can even deformation when riveting, forms a plurality of fixed bead 111, guarantees to wait to connect pipe fitting 200 can be compressed tightly sealedly by a plurality of fixed bead 111. The tension clip is provided so that the clip body 100 can be stably connected with the to-be-connected joint 300.
