如圖3所示,在本新型之第一實施例中,本新型之旋進式背栓螺絲1包括有本體10以及貫通該本體10之中心孔20,因而本體10為一中空管筒體。中心孔20為圓形狀,且中心孔20內之孔壁設有內螺紋21。本體10包括鎖固部11、兩夾持部13、兩固定部15及兩槽縫17。As shown in FIG. 3, in the first embodiment of the present invention, the screw-in
在本新型之第一實施例中,鎖固部11大致呈現圓柱狀,且鎖固部11相對應之兩側具有互為平行之側表面112。In the first embodiment of the present invention, the
在本新型之第一實施例中,兩夾持部13各自具有頭端131以及尾端133,各夾持部13之頭端131連接鎖固部11,且各夾持部13由頭端131至尾端133係逐漸朝中心孔20之中心靠近,亦即夾持部13由頭端131至尾端133係逐漸朝中心孔20之中心向內漸縮。In the first embodiment of the present invention, the two
在本新型之第一實施例中,兩固定部15分別連接各夾持部13之尾端133,且各固定部15具有內側面151及位於該內側面151之相反側的外側面153,其中內側面151位於中心孔20內,為中心孔20內之孔壁的一部分,故內側面151上設有內螺紋21。固定部15之外側面153由夾持部13之尾端133開始向外係逐漸朝中心孔20之中心遠離,亦即由尾端133開始朝遠離尾端133方向逐漸朝中心孔20之中心向外漸張,且外側面153設有複數齒塊1533。如圖4所示,在本實施例中,各固定部15之外側面153具有曲面段1531,複數齒塊1533之數量為四個,係以間隔等距呈弧線狀排列之方式設置於曲面段1531,但本新型不以此為限。In the first embodiment of the present invention, the two
如圖3所示,在本新型之第一實施例中,兩槽縫17分別位於任兩夾持部13與任兩固定部15之間。在本實施例中,各槽縫17之形狀大小均相同,且各槽縫17由夾持部13之頭端131至尾端133約略呈三角形狀,但本新型不以此為限。As shown in FIG. 3, in the first embodiment of the present invention, the two
接著請參考圖5及圖6。其中圖5係本新型之旋進式背栓螺絲之第二實施例之俯視圖;圖6係本新型之旋進式背栓螺絲之第二實施例之底視圖。Then please refer to FIG. 5 and FIG. 6. 5 is a top view of the second embodiment of the screw-in back bolt of the present invention; FIG. 6 is a bottom view of the second embodiment of the screw-in back bolt of the present invention.
如圖5所示,在本新型之第二實施例中,與前揭第一實施例不同的是,夾持部13、固定部15及槽縫17之數量為三個。如圖6所示,在本實施例中,各固定部15之外側面153的曲面段1531同樣分別設有四個間隔等距呈弧線狀排列之齒塊1533。相較於前揭所述之第一實施例,由於本實施例之固定部15數量為三個,且各固定部15之外側面153的曲面段1531同樣設有四個齒塊1533,故而齒塊1533總數量較多,且排列間隔較為密集,可提供較強的固定效果,惟本新型之齒塊1533設置並不以此為限。As shown in FIG. 5, in the second embodiment of the present invention, unlike the first embodiment disclosed above, the number of the
接著請參考圖7及圖8。其中圖7係本新型之旋進式背栓螺絲之第三實施例之俯視圖;圖8係本新型之旋進式背栓螺絲之第三實施例之底視圖。Then please refer to FIG. 7 and FIG. 8. 7 is a top view of the third embodiment of the screw-in back bolt of the present invention; FIG. 8 is a bottom view of the third embodiment of the screw-in back bolt of the present invention.
如圖7所示,在本新型之第三實施例中,與前揭各實施例不同的是,夾持部13、固定部15及槽縫17之數量為四個。同樣地,如圖8所示,在本實施例中,各固定部15之外側面153的曲面段1531亦分別設有四個間隔等距呈弧線狀排列之齒塊1533,但本新型不以此為限。As shown in FIG. 7, in the third embodiment of the present invention, different from the previous embodiments, the number of the
最後請參考圖9及圖10關於本新型之旋進式背栓螺絲使用之操作示意圖。Finally, please refer to FIG. 9 and FIG. 10 for the operation diagram of the new type of screw-in back bolt.
如圖9所示,本新型之旋進式背栓螺絲1在使用時,係先將旋進式背栓螺絲1安裝於物件60之孔洞中。接著將螺紋桿80旋入旋進式背栓螺絲1之中心孔20中。在螺紋桿80旋入過程中,原先由頭端131至尾端133逐漸朝中心孔20中心向內漸縮的複數夾持部13會在螺紋桿80的推抵擠壓下逐漸向外被撐開,而因槽縫17分開的複數固定部15也會隨之向外張開,朝著物件60之孔洞的孔壁擴張(如圖10所示)。由於固定部15之外側面153設有複數齒塊1533,因而在固定部15向外張開的過程,固定部15可藉由齒塊1533卡入物件60之孔壁,以進一步將咬緊該物件60,達到穩固裝設之目的。As shown in FIG. 9, when the screw-in
