Preferably, above-mentioned card locking mechanism is meant: the middle part outside surface of adapter is the polygon column, the back-up ring inboard is and the suitable polygon of polygon column, and the end face and the distance between the raised head face of the close boss of polygon column add the thickness of the thickness of O-ring seal more than or equal to nut.Polygon column and corresponding polygonal cooperation can be played anti-Sealing shield ring equally and take over the effect that relatively rotates, and the lifting surface area of polygon column is bigger when rotated, suffered external force is disperseed more, stressed also more even, polygon column and corresponding polygonal cooperation are also tighter, and result of use is better.
In order to obtain better technique effect, further technical measures also comprise:
Above-mentioned polygon column is a regular hexagon.More limit can make the column of adapter and being engaged in the loading process of nut skid easily, influence result of use, and its intensity of less limit is little than hexagon, be damaged easily, and material requested is also more, therefore, through taking all factors into consideration, the polygon column is that regular hexagon is preferred scheme.
The utility model compared with prior art has following beneficial effect:
1) using the utility model to install in the application of force process of water meter, get final product with a common spanner, the action required space is little, easy construction;
2) because external force is to act on the nut, therefore adapter can not be damaged, and has prolonged the serviceable life of taking over.
