It is equipped with and positions lug with the arc for compressing lug face；The card slot inner wall is provided with arc corresponding with the positioning lug
Shape locating slot；The compression lug surface is provided with strengthening rib strip；The compression Tab Thickness and the strengthening rib strip thickness it
With no more than the c-type button thickness.
Superelevation helical pitch screw pair buckle structure described in the utility model, wherein the strengthening rib strip is convex in the compression
Piece surface is provided with multiple.
Superelevation helical pitch screw pair buckle structure described in the utility model, wherein multiple strengthening rib strips are in the pressure
Tight lug surface is arranged in fan-shaped distribution.
Superelevation helical pitch screw pair buckle structure described in the utility model, wherein multiple described strengthening rib strip one end with
The c-type button is fixedly connected.
The beneficial effects of the utility model are：C-type button when mounted, passes through positioning lug and card slot inner wall thereon
Locating slot completes assembly positioning, and lug is compressed after assembly and pushes down circulator protrusion c-type latch portion surface, is contacted when increasing compression
Area, guarantee have enough pressing forces, avoid the occurrence of loosening situation, while enhancing circulator intensity, prevent the rolling of high-speed motion
Pearl damages circulator；It is arranged by strengthening rib strip, compresses the sum of lug and strengthening rib strip thickness and be not more than c-type button thickness, ensure
Intensity and globality, material saving.
