Description

旋進式背栓螺絲Screw-in back bolt

本新型係關於一種旋進式背栓螺絲，特別是一種可固定裝設於石材或複合板等物件上使用之旋進式背栓螺絲。The present invention relates to a screw-in type back-bolt screw, especially a screw-in type back-bolt screw that can be fixedly installed on objects such as stone or composite board.

習用用以固定石材等物件之固定裝置，如圖1所示，包括有一螺紋桿80及套筒90，其中螺紋桿80係穿設於套筒90中，該套筒90係由兩個形狀相同且對應之夾塊91組成，該等夾塊91上設有向外延伸之檔體92，且兩夾塊91相對應表面設有螺紋911，該螺紋911可與螺紋桿80上之螺紋相互螺合。The conventional fixing device for fixing stone and other objects, as shown in FIG. 1, includes a threaded rod 80 and a sleeve 90, wherein the threaded rod 80 is inserted into the sleeve 90, and the sleeve 90 is composed of two identical shapes And the corresponding clamping blocks 91 are formed, and the clamping blocks 91 are provided with outwardly extending stop bodies 92, and the corresponding surfaces of the two clamping blocks 91 are provided with threads 911, which can be screwed with the threads on the threaded rod 80 Together.

如圖2所示，使用時，先將夾塊91分別裝設於物件60預設之孔洞70中，再將螺紋桿80穿設在夾塊91中，使夾塊91上的螺紋911可與螺紋桿80上之螺紋相互螺合，令夾塊91在螺紋桿30擠壓下，逐漸向外擴張，使得檔體92因而可扣合在孔洞70之壁面上，以使夾塊91固定在孔洞70中。As shown in FIG. 2, when in use, first install the clamping blocks 91 in the predetermined holes 70 of the object 60, and then thread the rod 80 in the clamping blocks 91, so that the threads 911 on the clamping blocks 91 can be connected with The threads on the threaded rod 80 are screwed with each other, so that the clamping block 91 is gradually expanded outwards when the threaded rod 30 is pressed, so that the stopper 92 can be snapped on the wall surface of the hole 70 to fix the clamping block 91 in the hole 70.

惟因套筒90係由兩片單獨分開的板片體組成，故如物件60之體積過於龐大時，常會發生套筒90向外擴張但末端無法承受該物件60重量因而脫離該物件之情況，造成物件60由固定處掉落下來，使用上不甚理想。However, because the sleeve 90 is composed of two separate plates, so if the volume of the object 60 is too large, it will often happen that the sleeve 90 expands outward but the end cannot bear the weight of the object 60 and thus separates from the object. As a result, the object 60 falls from the fixed place, which is not ideal for use.

本新型之主要目的係在提供一種可穩固地裝設於石材或複合板等物件上使用之旋進式背栓螺絲。The main purpose of the present invention is to provide a screw-in back bolt that can be stably installed on stone or composite board and other objects.

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 fixing portions 15 are respectively connected to the tail ends 133 of the clamping portions 13, and each fixing portion 15 has an inner side surface 151 and an outer side surface 153 located on the opposite side of the inner side surface 151, wherein The inner side surface 151 is located in the center hole 20 and is a part of the hole wall in the center hole 20. Therefore, the inner side surface 151 is provided with an internal thread 21. The outer side surface 153 of the fixing portion 15 is gradually moved away from the tail end 133 of the clamping portion 13 toward the center of the center hole 20, that is, from the tail end 133 toward the direction away from the tail end 133 and gradually toward the center of the center hole 20 The outer side is gradually expanded, and the outer side surface 153 is provided with a plurality of tooth blocks 1533. As shown in FIG. 4, in this embodiment, the outer surface 153 of each fixing portion 15 has a curved surface segment 1531, and the number of the plurality of tooth blocks 1533 is four, which are arranged on the curved surface segment in an arc arrangement at equal intervals. 1531, but this new model is not limited to this.

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 slots 17 are respectively located between any two clamping portions 13 and any two fixing portions 15.

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 clamping portion 13, the fixing portion 15 and the slot 17 is three. As shown in FIG. 6, in this embodiment, the curved surface sections 1531 of the outer surface 153 of each fixing portion 15 are also provided with four tooth blocks 1533 arranged at equal intervals in an arc shape. Compared with the first embodiment described above, since the number of the fixing portions 15 in this embodiment is three, and the curved surface sections 1531 of the outer side surface 153 of each fixing portion 15 are also provided with four tooth blocks 1533, so the teeth The total number of blocks 1533 is relatively large, and the arrangement intervals are relatively dense, which can provide a strong fixing effect, but the arrangement of the tooth block 1533 of the present invention is not limited to this.

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 clamping portion 13, the fixing portion 15 and the slot 17 is four. Similarly, as shown in FIG. 8, in this embodiment, the curved surface sections 1531 of the outer surface 153 of each fixing portion 15 are also provided with four tooth blocks 1533 arranged at equal intervals in an arc shape, but the present invention does not This is limited.

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 back bolt 1 of the present invention is used, the screw-in back bolt 1 is installed in the hole of the object 60 first. Next, screw the threaded rod 80 into the central hole 20 of the screw-in back bolt 1. During the screwing-in process of the threaded rod 80, the plurality of clamping portions 13 that were gradually tapered inward from the head end 131 to the tail end 133 toward the center of the center hole 20 will be gradually supported outward by the thrust of the threaded rod 80 Opening, and the plurality of fixing portions 15 separated by the slot 17 will also expand outwards, expanding toward the hole wall of the hole of the object 60 (as shown in FIG. 10). Since the outer surface 153 of the fixing portion 15 is provided with a plurality of tooth blocks 1533, during the process of the fixing portion 15 flaring outward, the fixing portion 15 can be caught in the hole wall of the object 60 by the tooth blocks 1533 to further bite the Object 60 achieves the purpose of stable installation.

雖然本新型已以實施例揭露如上實施例，然其並非用以限定本新型，任何所屬技術領域中具有通常知識者，在不脫離本新型之精神和範圍內，當可作些許之更動與修飾，皆應為本專利所主張之權利範圍，故本專利之保護範圍當視後附之專利申請範圍所界定者為準。Although the present invention has disclosed the above embodiments with embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. , Should be the scope of rights claimed by the patent, so the scope of protection of this patent shall be deemed as defined by the scope of the attached patent application.
