Description
本創作係關於一種膨脹螺絲,尤其是一種可將一物件固定於一承重結構體的膨脹螺絲。The present invention relates to an expansion screw, and more particularly to an expansion screw that can fix an object to a load-bearing structure.
請參照第1圖所示,係揭示一種習知膨脹螺絲9,該膨脹螺絲9包含一螺桿91、一膨脹套筒92及一迫緊件93。該螺桿91可供該膨脹套筒92套設結合;該膨脹套筒92之外側周壁設有數道溝槽921,該數道溝槽921之間各形成一膨脹片922;該迫緊件93螺接於該螺桿91之一端,且該迫緊件93之外側周壁設有呈相對狀的二平面嵌掣部931,使該迫緊件93的外周輪廓於徑向截面上呈非正圓形,該二平面嵌掣部931則用以嵌掣於該膨脹套筒92之各膨脹片922的內側周壁。Referring to FIG. 1 , a conventional expansion screw 9 is disclosed. The expansion screw 9 includes a screw 91 , an expansion sleeve 92 and a pressing member 93 . The screw 91 is sleeved for the expansion sleeve 92; the outer peripheral wall of the expansion sleeve 92 is provided with a plurality of grooves 921, and an expansion piece 922 is formed between the plurality of grooves 921; The outer peripheral wall of the pressing member 93 is provided with two planar inlay portions 931, so that the outer peripheral contour of the pressing member 93 is non-circular in a radial cross section. The two-plane embedding portion 931 is configured to be embedded in the inner peripheral wall of each of the expansion sheets 922 of the expansion sleeve 92.
上述膨脹螺絲9於實際使用時,可將如壁板或置物架等各式物件藉由該膨脹螺絲9固定於一承重結構體(如牆壁或地板等)。於安裝過程中,該膨脹螺絲9可穿設於該承重結構體之一鑽孔中,再以一外力旋動該螺桿91,藉由該螺桿91及該迫緊件93的螺接關係,以及配合該迫緊件93之二平面嵌掣部931嵌掣於該膨脹套筒92之各膨脹片922的設計,可在限制該迫緊件93無法轉動的前提下,迫使該迫緊件93線性移動以推抵各膨脹片922形成徑向擴張,使該數個膨脹片922可抵緊於該承重結構體之鑽孔,以完成該膨脹螺絲9之安裝作業。When the expansion screw 9 is actually used, various items such as a wall panel or a shelf can be fixed to a load-bearing structure (such as a wall or a floor, etc.) by the expansion screw 9. During the installation, the expansion screw 9 can be inserted into one of the bores of the load-bearing structure, and then the screw 91 is rotated by an external force, and the screwing relationship between the screw 91 and the pressing member 93, and The design of the expansion piece 922 of the expansion sleeve 92 is matched with the design of the expansion piece 922 of the expansion sleeve 92, and the tension member 93 can be forced to linearly under the condition that the pressing member 93 cannot be rotated. The movement is performed to push the expansion sheets 922 to form a radial expansion, so that the plurality of expansion sheets 922 can abut against the bore of the load-bearing structure to complete the installation work of the expansion screws 9.
上述膨脹螺絲9的安裝過程中,當旋動該螺桿91以迫使該 迫緊件93移動並推抵該數個膨脹片922形成徑向擴張時,雖然可利用該迫緊件93之二平面嵌掣部931嵌掣於該膨脹套筒92之各膨脹片922的定位作用,以防止該迫緊件93隨著該螺桿91旋轉而於該膨脹套筒92內側形成空轉。然而,如第2圖所示,隨著該數個膨脹片922逐漸形成徑向擴張,該迫緊件93之二平面嵌掣部931將更不易嵌掣於該膨脹套筒92之各膨脹片922的內側周壁,甚至造成該二平面嵌掣部931形成無受力部位,因此,該迫緊件93仍可能會隨著該螺桿91旋轉,而於該膨脹套筒92內側形成空轉情形,致使該數個膨脹片922最終未能形成極大化的徑向擴張狀態,造成該數個膨脹片922無法確實抵緊於該承重結構體之鑽孔,故習知膨脹螺絲9具有安裝便利性不佳及固定效果不佳等諸多問題尚待解決。During the installation of the above-mentioned expansion screw 9, when the screw 91 is rotated to force the When the pressing member 93 moves and pushes against the plurality of inflatable sheets 922 to form a radial expansion, the positioning of each of the expansion sheets 922 of the expansion sleeve 92 can be utilized by the two planar caulking portions 931 of the pressing member 93. Acting to prevent the pressing member 93 from forming an idle motion inside the expansion sleeve 92 as the screw 91 rotates. However, as shown in FIG. 2, as the plurality of expansion sheets 922 gradually form a radial expansion, the two planar caulking portions 931 of the pressing members 93 will be less likely to be embedded in the respective expansion sheets of the expansion sleeve 92. The inner peripheral wall of the 922 even causes the two-plane embedding portion 931 to form a non-stressed portion. Therefore, the pressing member 93 may still rotate with the screw 91 to form an idling condition inside the expansion sleeve 92, thereby causing a idling condition. The plurality of expansion sheets 922 eventually fail to form a maximized radial expansion state, so that the plurality of expansion sheets 922 cannot be surely abutted against the bore of the load-bearing structure, so that the conventional expansion screw 9 has poor installation convenience. And many problems such as poor fixing effect have yet to be resolved.
