Inserting-connection retaining structure and prefabricated part combination
The invention discloses an inserting-connection retaining structure and a prefabricated part combination. The inserting-connection retaining structure comprises an outer sleeve, an insertion rod, an annular retainer and a guide ring; the outer sleeve is provided with a containing cavity, a reducing inserting-connection joint capable of extending into the containing cavity is formed at the axial end of the inserting rod; the annular retainer annularly sleeves the periphery of the reducing inserting-connection joint and is sealed and covered in the containing cavity by the guide ring, two or more notches are formed in the end, close to the guide ring, of the annular retainer in the circumferential direction at intervals, and arc-shaped clamping blocks with the outer circumferential width being greater than the inner circumferential width are contained in the notches and to reversely clamp the reducing inserting-connection joint; and the inner width of the notch is smaller than the outerwidth of the arc-shaped clamping blocks and greater than the inner width of the arc-shaped clamping blocks so that the arc-shaped clamping blocks can move in the axial direction and/or the radial direction of the annular retainer. The inserting-connection retaining structure can prevent a clamping piece and a spring from falling or rolling over, can guarantee the inserting-connection success rateand the anti-pull retaining effect, and has better connection convenience and connection strength.
本发明公开一种插接止退结构和预制构件组合，所述插接止退结构包括外套筒、插杆、环状保持架以及导正环，其中，外套筒具有一容纳腔，插杆的轴向一端形成可伸入容纳腔中的变径插接头，环状保持架环套在变径插接头的外围且由导正环封盖在所述容纳腔内，环状保持架于靠近导正环的一端部沿周向间隔开设有两个以上豁口，豁口内容纳有外周宽大于内周宽的弧形卡块用以逆向卡止变径插接头；豁口的内宽小于弧形卡块的外宽且大于弧形卡块的内宽以使弧形卡块能够沿环状保持架的轴向和/或径向移动。该插接止退结构能够防止卡片和弹簧掉落或倾翻，能够保证插接成功率和抗拔止退效果，具有更好的连接便捷性和连接强度。
