如上所述，本創作實施例的鎖固裝置100，藉由接合機構102可先將基板工件(未繪示)夾制在扣部110與第一開口106之間，從而無須藉由焊接或鉚接的方式。此外，該鎖固裝置100也可藉由反向操作由基板工件拆下，以重複使用。 As mentioned above, in the locking device 100 of the present invention, the substrate workpiece (not shown) can be clamped between the buckle 110 and the first opening 106 by the joint mechanism 102, so that there is no need for welding or riveting. The way. In addition, the locking device 100 can also be detached from the substrate workpiece by reverse operation, so as to be reused.

如圖1及圖2所示，在一實施例中，該定位套筒103可更包括一第四止擋凸部112，該第二止擋凸部108位於該第一止擋凸部107與該第四止擋凸部112之間，該第四止擋凸部112適於在該第三止擋凸部111越過該第二止擋凸部 108後，限制該第三止擋凸部111的移動極限。該鎖固機構101可包括一操作筒113、一鎖固件114以及一鎖固彈簧115。該操作筒113具有環套該定位套筒103外部的一套筒部116、及連接於該套筒部116且相對該第四止擋凸部112的一帽蓋部117。該套筒部116與該帽蓋部117並定義供該定位套筒103伸縮活動的一活動空間S。該鎖固件114固定連接於該帽蓋部117且延伸出該接合套筒104的一第二開口118。該套筒部116的一端內緣與該定位套筒103的一端外緣可分別呈彎折狀，以使該操作筒113與該定位套筒103保持可活動但不致脫離的狀態。 As shown in Figures 1 and 2, in one embodiment, the positioning sleeve 103 may further include a fourth stop protrusion 112, the second stop protrusion 108 is located between the first stop protrusion 107 and Between the fourth stop protrusions 112, the fourth stop protrusions 112 are adapted to pass over the second stop protrusions when the third stop protrusions 111 After 108 , limit the movement limit of the third stop convex portion 111 . The locking mechanism 101 can include an operating cylinder 113 , a locking member 114 and a locking spring 115 . The operating cylinder 113 has a sleeve portion 116 surrounding the positioning sleeve 103 , and a cap portion 117 connected to the sleeve portion 116 and opposite to the fourth stop protrusion 112 . The sleeve portion 116 and the cap portion 117 together define an activity space S for the positioning sleeve 103 to expand and contract. The locking member 114 is fixedly connected to the cap portion 117 and extends out of a second opening 118 of the engaging sleeve 104 . An inner edge of one end of the sleeve portion 116 and an outer edge of an end of the positioning sleeve 103 can be respectively bent, so that the operating cylinder 113 and the positioning sleeve 103 can be kept movable but not detached.

如圖1及圖2所示，在一實施例中，該鎖固彈簧115位於該活動空間S中且環繞該鎖固件114。該鎖固彈簧115抵頂於該第四止擋凸部112與該帽蓋部117之間。當該接合機構102接合於基板工件後，可使用該鎖固機構101將待鎖工件(未繪示)鎖固到基板工件上。該鎖固件114可具有外螺紋，該操作筒113適於相對該定位套筒103旋轉，以藉由螺接方式將待鎖工件加以鎖固。但並不僅限於此，該鎖固機構101也可為其他的形式，例如按壓扣接等。該鎖固機構101可更包括一帽套件119。該帽套件119環套且固定於該套筒部116的外側，且表面具有便於握持的紋路T，以方便使用者操作轉動。該接合彈簧105的彈力可大於該鎖固彈簧115，因此當該鎖固機構101進行鎖固之作動時，該鎖固彈簧115施加於該接合機構102的彈力對該接合彈簧105不生影響，該接合機構102仍可扣緊於基板工件。 As shown in FIGS. 1 and 2 , in one embodiment, the locking spring 115 is located in the movable space S and surrounds the locking member 114 . The locking spring 115 abuts between the fourth stop protrusion 112 and the cap portion 117 . After the engaging mechanism 102 is engaged with the substrate workpiece, the locking mechanism 101 can be used to lock the workpiece to be locked (not shown) on the substrate workpiece. The locking member 114 may have an external thread, and the operating cylinder 113 is adapted to rotate relative to the positioning sleeve 103 so as to lock the workpiece to be locked by screwing. But it is not limited thereto, and the locking mechanism 101 can also be in other forms, such as press buckle and so on. The locking mechanism 101 can further include a cap set 119 . The cap set 119 surrounds and is fixed on the outer side of the sleeve portion 116 , and has a texture T on the surface for easy handling, so as to be convenient for the user to operate and rotate. The elastic force of the engaging spring 105 can be greater than that of the locking spring 115, so when the locking mechanism 101 is locked, the elastic force applied by the locking spring 115 to the engaging mechanism 102 has no effect on the engaging spring 105. The engagement mechanism 102 can still be fastened to the substrate workpiece.

如圖3至圖8所示並配合參考圖1及圖2，在一實施例中，該扣部110的外周緣可呈非圓形的環繞形狀。該定位套筒103於該第一開口106的外周緣可具有對應該扣部110的形狀，例如為凸階的一置入部120(如圖2所示)。該扣部110的外周緣可具有彼此平行的兩個側邊L。該基板工件可具有對應該扣部110的外 周緣形狀的開孔(未繪示)。該扣部110可整體通過該開孔，該置入部120則可置入該開孔中，使該接合機構102整體相對該基板工件不可轉動。該定位套筒103可更設有一止擋片121(如圖1及圖2所示)以與基板工件的開孔之孔緣對應止擋。當該扣部110被轉動而錯位於該開孔，並同時被該接合彈簧105拉回時，就可扣緊該基板工件。相對地，該第三止擋凸部111的外周緣可具有兩相對的凹部R(如圖3及圖6)、均勻分配於環周的三個凹部R(如圖4及圖7)、或均勻分配於環周的四個凹部R(如圖5及圖8)。該等凹部R可為經加工所形成的線紋。該第二止擋凸部108所圍繞成的開孔可對應該第三止擋凸部111的外周緣的結構，惟在進行接合前是呈錯位，以可被該第二止擋凸部108所止擋，當轉動至對應的位置時，該接合彈簧105的彈力獲得釋放而推抵該第三止擋凸部111，使該第三止擋凸部111越過該第二止擋凸部108。 As shown in FIGS. 3 to 8 and with reference to FIGS. 1 and 2 , in an embodiment, the outer peripheral edge of the buckle portion 110 may be in a non-circular surrounding shape. The positioning sleeve 103 may have a shape corresponding to the buckle portion 110 on the outer periphery of the first opening 106 , for example, an inserting portion 120 (as shown in FIG. 2 ) that is a convex step. The outer peripheral edge of the buckle portion 110 may have two sides L parallel to each other. The substrate workpiece may have an outer surface corresponding to the button portion 110 Peripheral shaped openings (not shown). The buckle part 110 can pass through the hole as a whole, and the inserting part 120 can be put into the hole, so that the joint mechanism 102 can not rotate relative to the substrate workpiece as a whole. The positioning sleeve 103 can be further provided with a stop piece 121 (as shown in FIG. 1 and FIG. 2 ) to stop corresponding to the edge of the hole of the substrate workpiece. When the buckle 110 is rotated to be dislocated in the opening and simultaneously pulled back by the engagement spring 105 , the substrate workpiece can be fastened. In contrast, the outer peripheral edge of the third stop protrusion 111 can have two opposite recesses R (as shown in Figures 3 and 6), three recesses R evenly distributed around the circumference (as shown in Figures 4 and 7), or The four recesses R are evenly distributed on the circumference (as shown in Fig. 5 and Fig. 8). The recesses R may be lines formed by processing. The opening surrounded by the second stop protrusion 108 can correspond to the structure of the outer periphery of the third stop protrusion 111, but it is dislocated before the engagement, so that it can be used by the second stop protrusion 108. When turning to the corresponding position, the elastic force of the engagement spring 105 is released and pushed against the third stop convex portion 111, so that the third stop convex portion 111 passes over the second stop convex portion 108 .

如圖9所示，圖9與圖1及圖2之實施例大致相同。相異處僅在於無設有圖1及圖2的止擋片121，而藉由置入部120與定位套筒103之間形成的凸階與基板工件的開孔之孔緣進行止擋。相較於圖1及圖2，圖3顯示的鎖固件114因作動而具有更長延伸出第二開口118的部分。與前述實施例相同的部分不再重複敘述。 As shown in FIG. 9 , FIG. 9 is substantially the same as the embodiment shown in FIG. 1 and FIG. 2 . The only difference is that there is no stop piece 121 as shown in FIG. 1 and FIG. 2 , but the stop is made by the raised step formed between the insertion part 120 and the positioning sleeve 103 and the hole edge of the substrate workpiece. Compared with FIG. 1 and FIG. 2 , the locking member 114 shown in FIG. 3 has a longer portion extending out of the second opening 118 due to its actuation. Parts that are the same as those in the foregoing embodiments will not be described again.

請參閱圖10，其顯示本創作另一具體實施例的鎖固裝置100。本實施例與圖1、2實施例大致相同，差異主要在於帽套件119具有紋路T的區域較窄。與前述實施例相同的部分不再重複敘述。 Please refer to FIG. 10 , which shows a locking device 100 according to another specific embodiment of the present invention. This embodiment is substantially the same as the embodiment shown in FIGS. 1 and 2 , the main difference being that the area where the cap set 119 has the lines T is narrower. Parts that are the same as those in the foregoing embodiments will not be described again.

請參閱圖11，其顯示本創作另一具體實施例的鎖固裝置100。本實施例與圖1、2實施例大致相同，差異主要在於該扣部110與置入部120的外周緣整體呈多邊形。與前述實施例相同的部分不再重複敘述。 Please refer to FIG. 11 , which shows a locking device 100 according to another specific embodiment of the present invention. This embodiment is substantially the same as the embodiment shown in FIG. 1 and FIG. 2 , the main difference is that the outer peripheral edges of the buckle portion 110 and the insertion portion 120 are generally polygonal.
