Abstract
The utility model discloses a back ferrule for a pipeline connector, comprising a back ferrule body. The middle part of the back ferrule body is provided with a ring groove, wherein the ring groove is arranged on the internal surface or external surface of the back ferrule body. Compared with prior art, the utility model has the characteristics of tight gripping.
Description
Technical field
The utility model relates to a kind of pipe coupling cutting ferrule, the back card of especially two card cutting ferrules.
Background technique
In the connection of pipeline, pipe coupling not only will be played seal action, also will take into account the effect of fixing chucking pipeline simultaneously, two card cutting ferrules, preceding card is used for sealing, the back card is used for fixing, thereby is more and more adopted by people, because the body middle part cylindrical cross-section thickness of back card is bigger, fixedly the time, stressed not yielding, thereby fixed effect is not good enough yet.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of fixing more firm rear cutting ferrule is provided.
For solving the problems of the technologies described above, the utility model adopts following technological scheme, and it comprises back card body, and described back is provided with an annular groove on the card body middle part.
Described annular groove is arranged on the internal surface or the outer surface of back card body.
Compared with prior art, one annular groove is set, has reduced the section thickness of middle part cylinder, thereby when stressed, be easy to produce big distortion at the middle part of back card body, pipeline is fixed.Annular groove can be arranged on the internal surface or the outer surface of back card body, and is easy to process.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated, as shown in Figure 1, it comprises back card body 1, back card body 1 front end is arranged to the conical surface, adapts to card rear cone before the cutting ferrule, on the middle part cylinder of back card body, be provided with an annular groove 11, this groove 11 is arranged on the outer surface of back card body.This groove also can be arranged on the internal surface of back card body.
Claims (2)
1. a rear cutting ferrule that is used for pipe coupling comprises back card body (1), it is characterized in that on described back card body (1) middle part annular groove (11) being set.
2. rear cutting ferrule according to claim 1 is characterized in that described annular groove (11) is arranged on the internal surface or the outer surface of back card body (1).
