Abstract
The utility model provides a fastening device of pressing mode inflating valve, including the nut, the lower extreme outside of nut is provided with the ring channel, fastening device still is provided with the packing ring, the packing ring is provided with connecting portion, connecting portion be provided with with the position of ring channel joint, and do not screw up at the nut and go forward at the inflating valve, packing ring and nut can rotate relatively. The utility model discloses nut and gasket had both assembled together, can rotate relatively again, can reach the accuracy and pair, can not trade the mistake or lose, guaranteed total weight and the uniformity of connecting the fastening, and when ensureing the fastening connection again, the packing ring can be in best cooperation state, and fastens convenient operation. So but because nut and gasket rotation can not produce the friction at fastening process packing ring with the rim, avoided the rim to cause surface damage because of the friction.
Description
Technical field
This utility model relates to valve cock, particularly relates to the retention mechanism of a kind of clamp-in valve.
Background technology
Clamp-in valve uses nut to be fixed on wheel rim by valve cock as securing member, and in some clamp-in valve fastening standard, this fastening means needs to configure packing ring to prevent wheel rim from damaging.For valve cock, need to consider its be installed on wheel after impact on dynamic wheel balancing, therefore, the requirement to himself structure and fastening accessory needs the most accurate.
Summary of the invention
Technical problem to be solved in the utility model is to provide the retention mechanism of a kind of clamp-in valve, not only facilitates installation but also be easy to accurately control the gross weight of the retention mechanism of valve cock and connect the concordance of fastening.To this end, this utility model is by the following technical solutions:
A kind of retention mechanism of clamp-in valve, including nut, it is characterized in that, the lower end outside of described nut is provided with cannelure, described retention mechanism is additionally provided with packing ring, and described packing ring is provided with connecting portion, and described connecting portion is provided with and the position of described cannelure clamping, and be not tightened in valve cock at nut and go forward, described packing ring and nut can relatively rotate.
Further, the connecting portion of packing ring is in set jacket at the lower end outside of nut, and the inner side of described connecting portion arranges the position with described cannelure clamping.
Further, the lower end of described nut has step, and connecting portion is formed spacing by described step.
Further, the upper end at the described position with described cannelure clamping has arc transiting surface.
Further, the cross section of the assembly of described packing ring and connecting portion is L-shaped.
Owing to using the technical solution of the utility model, this utility model nuts and washers was both assembled together, can relatively rotate again, can either perfect match, mistake or loss will not be changed, it is ensured that gross weight and connect the concordance of fastening, also ensure that when being fastenedly connected, packing ring can be in best fit state, and tightening operation is convenient.Owing to nuts and washers can mutually rotate so will not produce friction at fastener cycle packing ring and wheel rim, it is to avoid wheel rim causes surface damage because of friction.
Accompanying drawing explanation
Fig. 1 is the exploded view of this utility model embodiment shown with section view.
Detailed description of the invention
