Abstract
The utility model discloses a clamp type threaded joint which comprises a joint end and pipefitting. The joint end is provided with an annular protruding edge. The end face of the joint end is provided with an annular groove. The section of the annular groove is provided with a main square groove body, a narrowing part with a side wall in arc-shaped smooth transition and a circular clamping part which are communicated with one another. The width of the narrowing part is smaller than the width of the main square groove body and the circular clamping part. A sealing ring matched with the annular groove in shape is arranged in the annular groove. In the clamp type threaded joint, due to the fact that the annular groove is provided with a narrowing part with relatively small width, and the side wall of the narrowing part is in smooth transition, when a user places the sealing ring matched with the annular groove in shape is plugged into the annular groove, a position, in front of the sealing ring, of the circular section can be directly clamped into the circular clamping part of the annular ring due to elasticity, so that the sealing ring can be firmly clamped in the annular groove. The clamp type threaded joint is simple in structure and can effectively prevent the sealing ring from coming off.
Description
Technical field
The utility model relates to a kind of clamp band type threaded joint.
Background technique
Tradition clamp band type threaded joint comprises tip side and pipe fitting, described tip side is with convex annular edge, the end face of described tip side is with circular groove, in circular groove, snapped in seal ring, but these seal rings and circular groove general section are circular, and clamp band type screw thread seal ring when not installing is all exposed, be therefore easy to come off.
Model utility content
In view of the deficiency that background technique exists, technical problem to be solved in the utility model has been to provide a kind of simple in structure and can prevent the clamp band type threaded joint that seal ring comes off.
The utility model takes following technological scheme to complete: clamp band type threaded joint, comprise tip side and pipe fitting, described tip side is with convex annular edge, the end face of described tip side is with circular groove, the cross section of described circular groove has the square major trough body communicating, the portion that narrows and the circular snapin part of sidewall curved circular degree of slipping over, the described width that narrows portion is less than the width of square major trough body and circular snapin part, inserts the seal ring that tangible shape mates with circular groove in circular groove.
In the utility model, because circular groove has the portion that narrows that width is relatively little, and the sidewall that narrows portion is rounding off, when seal ring shape being mated with circular groove as user is filled in circular groove, the circular cross-section place of seal ring front portion can directly snap in the circular snapin part of circular groove owing to having elasticity, thereby seal ring can be firmly stuck in circular groove.Said structure of the present utility model is very simple, and can effectively prevent that seal ring from coming off.
Accompanying drawing explanation
The utility model has following accompanying drawing:
The structure cross-sectional schematic of the clamp band type threaded joint that Fig. 1 provides for the utility model.
Embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, further describes by reference to the accompanying drawings each details and the working principle thereof of embodiment below again.
As shown in Figure 1, the clamp band type threaded joint that the utility model the first embodiment provides, comprise tip side 1 and pipe fitting 2, described tip side 1 with convex annular along 3, the end face of described tip side 1 is with circular groove 4, the cross section of described circular groove 4 has the square major trough body 41 communicating, the portion that narrows 42 and the circular snapin part 43 of sidewall curved circular degree of slipping over, the described width that narrows portion 42 is less than the width of square major trough body 41 and circular snapin part 43, inserts the seal ring 5 that tangible shape mates with circular groove 4 in circular groove 4.The rear portion of pipe fitting 2 has threaded ends 6.
Claims (2)
1. a clamp band type threaded joint, comprise tip side and pipe fitting, described tip side is with convex annular edge, the end face of described tip side is with circular groove, it is characterized in that: the cross section of described circular groove has the square major trough body communicating, the portion that narrows and the circular snapin part of sidewall curved circular degree of slipping over, the described width that narrows portion is less than the width of square major trough body and circular snapin part, inserts the seal ring that tangible shape mates with circular groove in circular groove.
