參閱圖2至圖5，該等限位裝置2適用於裝設在例如該感測器主體1的物件上，並可調整位置地卡固於一溝槽201中。各限位裝置2包括一安裝座3及一限位旋桿4，該限位旋桿4是可移出且可旋轉地裝設於該安裝座3中，具體實施方式說明如下。
Referring to FIG. 2 to FIG. 5 , the limiting
參閱圖4、圖5、圖8及圖9，該安裝座3包括一底壁31、一由該底壁31的一側向上凸伸的第一立壁32、一由該底壁31的另一側向上凸伸且與該第一立壁32間隔相對的第二立壁33、一設置於該第一立壁32及該第二立壁33之同一側(圖5中位於左上方)的擋止結構35，以及一設置於該第一立壁32及/或該第二立壁33之另一側(圖5中位於右下方)且與該擋止結構35間隔相對的箝制結構34。
4 , 5 , 8 and 9 , the mounting
該安裝座3的底壁31於頂面形成一可供該限位旋桿4的底端插設其中的凹孔311。該第一立壁32及該第二立壁33的其中一者的外表面形成一用於與該物件(也就是該感測器主體1)卡接的卡接槽331，本實施例中該卡接槽331例如是形成於該第二立壁33之遠離該第一立壁32的一側，並且以例如鳩尾槽的形態實現，因而能與鳩尾榫形態的該卡接結構13相互卡掣，但視實際需要，該卡接槽331及該卡接結構13的結構形態均可調整，不以上述實施方式為限。該擋止結構35於本實施例中例如是以如圖4般之兩端分別連接該第一立壁32及該第二立壁33且間隔於該底壁31的橫條狀結構來實現，當該限位旋桿4裝設在該安裝座3內時可由該擋止結構35對該限位旋桿4的一側提供擋止效果，避免該限位旋桿4從該擋止結構35的一側脫出該安裝座3。該箝制結構34具有兩個間隔相對且分別設置於該第一立壁32及該第二立壁33的凸塊341，該等凸塊341之間的空間可供該限位旋桿4的特定部位(說明於後)穿入該安裝座3中，此外在該限位旋桿4安裝在該安裝座3後可由該等凸塊341對該限位旋桿4造成限位效果。然而，該箝制結構34也可以只形成一個凸塊341，單個凸塊341可裝設在該第一立壁32及該第二立壁33的任一者，同樣能實現上述功用。
The
參閱圖4、圖5、圖8及圖10，該底壁31、該第一立壁32及該第二立壁33配合界定一用於容納該限位旋桿4的置桿槽36。該置桿槽36具有一桿頭槽部361、一連通該桿頭槽部361的桿身槽部362及一連通該桿身槽部362且鄰近該底壁31的擴張槽部363。該桿頭槽部361顯露於該第一立壁32、該第二立壁33、該擋止結構35及該箝制結構34之頂側，且較該桿身槽部362遠離該底壁31，
並具有大於該桿身槽部362的槽寬。該桿身槽部362的槽寬小於該擴張槽部363，且該桿身槽部362在對應該箝制結構34的一側具有一開口(於圖5中此開口是朝向右下方)，該開口在該箝制結構34處的寬度小於其他部位。該擴張槽部363呈底寬頂窄狀，並在對應該擋止結構35及該箝制結構34之側各形成一透口。本實施例中，該擴張槽部363的該等透口各呈鐘形，以對應該限位旋桿4的結構形態。
Referring to FIG. 4 , FIG. 5 , FIG. 8 and FIG. 10 , the
參閱圖5~8、圖12，該限位旋桿4的形貌類似不具螺紋的異型螺絲，其包括一桿身41、一設於該桿身41之頂端且徑寬大於該桿身41的桿頭42，以及兩個旋轉對稱地設置於該桿身41的相反側的卡塊43。
Referring to FIGS. 5 to 8 and 12 , the shape of the limiting
該桿頭42的徑寬介於該桿頭槽部361的槽寬及該桿身槽部362的槽寬之間，因此可容納於該桿頭槽部361中但無法進入該桿身槽部362中。此外，該桿頭42的頂端配合例如為內六角板手的該安裝工具300而形成如圖所示的內六角鎖孔，以便於藉由該安裝工具300來進行旋轉卡固之操作。然而，該桿頭42用於與該安裝工具300配合使用所形成的結構不以內六角鎖孔為限，當視實際需要而定。
The diameter of the
該桿身41的側面內凹形成至少一凹截部411，於本實施例是以該桿身41的側面形成二位於相反側的凹截部411來實施。該桿身41在對應該等凹截部411處的徑寬小於其他部位，且該桿身之對應該等凹截部處的徑寬是與該桿身槽部362之該開口在該等凸塊341之間的34寬度相對應。如此一來，該限位旋桿4只有在該等凹截部411的部位對準該等凸塊341之間的位置時，才能順利
裝入該置桿槽36中，若以非該等凹截部411的部位對準該等凸塊341之間的位置，該限位旋桿4會被該等凸塊341擋止而無法進入該置桿槽36中。相應的，該限位旋桿4位於該置桿槽36中時，若該等凹截部411未對準該等凸塊341時會讓該限位旋桿4被限位，使得該限位旋桿4不能脫離該安裝座，藉以實現固定的作用。
The side surface of the
該等卡塊43呈底厚頂薄狀，且分別具有一從該桿身41橫向延伸的底面431，以及一由該底面431之外緣向上傾斜延伸並連接該桿身41而呈弧面狀的卡抵斜面432。各卡塊43呈底厚頂薄狀，並由該卡抵斜面432界定出具漸變高度及漸變厚度之結構。具體來說，各卡塊43在該桿身41的長度方向上具有漸變厚度，並在該桿身41底視的順時針環繞方向上具有漸變高度，大致來說在該桿身41的長度方向上各卡塊43厚度較小的部位具有較低的高度。例如以圖6中位於右側的卡塊43為例，該卡塊43於圖7是位於右上側，其左側(標示A處)的高度較右側的高度低，且從圖7可知該側(標示A處)的厚度較另一側(標示B處)小。藉由該等卡塊43的結構形態配置，能讓該等限位裝置2藉由各限位旋桿4的旋轉而讓該等卡塊43從該置桿槽36中凸出而卡抵在該溝槽201的內壁頂側，且具有漸變高度及漸變厚度的結構配置適用於不同規格形狀的溝槽201的卡抵固定。
The
參閱圖5、圖8至圖11，該限位旋桿4可在不使用工具的情況下裝設在該安裝座3處，同樣地也可以在不使用工具的情況下從該安裝座3中移出。當需要將該限位旋桿4裝設在該安裝座3處時，可將該桿頭42對準該桿頭槽部361、將該桿身41的該等凹截部411分別對準該箝制結構34的該等凸塊341，並將
該等卡塊43對準該擴張槽部363，如此就能如圖8、圖9般讓該限位旋桿4順利地從該桿身槽部362的開口及該擴張槽部363的透口置入該置桿槽36中。隨後，可如圖10、圖11般將該桿身41的底端插設於該安裝座3的凹孔311中，便完成該限位旋桿4的裝設。完成裝設後，雖然該擴張槽部363的高度及寬度大於該等卡塊43而使該限位旋桿4能沿凹孔311上下移動並能在該置桿槽36中旋轉，但該限位旋桿4會由該底壁31的頂面及該桿身槽部362的底側對該等卡塊43上下限位，並由該底壁31、該第一立壁32、該第二立壁33、該箝制結構34及該擋止結構35之配合來限制該限位旋桿4在側向上的移動範圍，因而能確保該限位旋桿4在該等凹截部411未對準該等凸塊341時無法脫離該安裝座3。相應地，若需要將該限位旋桿4從該安裝座3中移出，只要將該限位旋桿4提起，並讓該等凹截部411對準等凸塊341(也就是該桿身41的徑寬最窄處對準該開口的最窄處)，就能將該限位旋桿4移出該置桿槽36。
Referring to Figure 5, Figure 8 to Figure 11, the limiting
參閱圖1、圖2、圖12至圖14，當需要安裝該磁性感測器100於該壓力缸200時，可先將該等限位裝置2藉由該等卡接槽331裝設於該感測器主體1的該等卡接結構13處，並讓該限位旋桿4的該等卡塊43收容於該擴張槽部363中。隨後，可將該等限位裝置2以及該感測器主體1的該底座12由上方或前後側裝入擇定的溝槽201中。由於在安裝過程中該限位旋桿4的該等卡塊43是容置在該擴張槽部363內而未側向突出至該安裝座3之外，因此可以從該溝槽201的上方直接將該磁性感測器100置入該溝槽201中，不用擔心該等卡塊43會阻礙安裝的進行，而且也讓使用者不限於只能從該溝槽201的前端或後段進行該磁性感
測器100的安裝。將該磁性感測器100置於預定位置後，可藉由該安裝工具300施力於該限位旋桿4的該桿頭42，讓該限位旋桿4***作而依自身軸線旋轉，使得該等卡塊43在收容於該擴張槽部363中的狀態以及從該等透口處凸出的狀態變換。如圖14所示，該等卡塊43從該等擴張槽部363的透口凸出時能卡抵於該溝槽201的內壁頂側，因而能提供卡抵固定的效果，將該磁性感測器100牢靠地固定於該壓力缸200上。而且，由於該等卡塊43的漸變高度及漸變厚度的結構配置，能夠靈活地運用於不同形狀的溝槽201，例如該溝槽201從圖式中的C形槽變換為T形槽，或是大小形狀有所改變時，都能夠藉由相同的該等限位裝置2來進行該磁性感測器100的固定，如此能增進使用上的彈性及便利性。
Referring to FIG. 1 , FIG. 2 , and FIGS. 12 to 14 , when the
參閱圖15及圖16，為該限位裝置2的變化實施態樣。與前述實施方式相比，此變化實施態樣的主要差異在於該限位旋桿4僅具有一桿身41及兩卡塊43，未形成如前述的徑寬較大的桿頭42。相應的，該安裝座3的該置桿槽36僅具有對應該桿身41的一桿身槽部362及對應該等卡塊43的一擴張槽部363，而未形成如前述的槽寬較大的桿頭槽部361。然而，在此變化實施態樣中，該限位旋桿4仍能以該等凹截部411側向對準該等凸塊341的方式裝設於該安裝座3中，並且同樣能藉由旋轉的方式讓該等卡塊43卡抵於溝槽201的內壁，藉以實現固定之作用。
Referring to FIG. 15 and FIG. 16 , it is a modified embodiment of the limiting
綜合上述，本發明磁性感測器100及限位裝置2能藉由該限位旋桿4之該等卡塊43的配置，簡便地透過對該限位旋桿4的旋轉操作而讓該等卡塊43卡固在溝槽201的內壁處，如此便於進行該磁性感測器100的拆裝及安裝位置的
變換。此外，藉由該等卡塊43之漸變高度及漸變厚度的結構配置，使得該等限位裝置2能夠裝設在不同結構形態的溝槽201中，增進使用上的彈性及便利性。因此，本發明磁性感測器100及限位裝置2確實能達成本發明的目的。
