Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a rail device. [Prior Art] [0002] Sliding device is widely used in a rack server, which is connected between a server rack and a server, and the server is slidably mounted on a server rack. [0003] A common rail device has a three-section slide rail, which generally includes an outer rail, a middle rail, and an inner rail. The outer rail is fixed to the servo frame, and the inner rail is fixed to both sides of the servo server. The middle rail is connected as a receiving rail between the outer rail and the inner rail to
延伸伺服器的活動範爵，並且使得内軌及中軌可以沿著 該外軌的軸線方向相對於外軌來回滑動，因此，伺服器 就可以透過滑軌裝置自由地被拉出或推回MExtending the activity ruler of the server, and allowing the inner rail and the middle rail to slide back and forth relative to the outer rail along the axial direction of the outer rail, so that the server can be freely pulled out or pushed back through the rail device.
[0004] 在伺服器拉出過程中，伺服器作用於中軌的力與外轨對 中轨支撐力之間形成一力矩。伺服器拉出越遠，外軌對 中轨的作用力越大。若在内轨拉出中轨的蟲程中，中軌 ^ 同時拉出外轨，一方面由於外軌對中軌支撐力增大使得 摩擦力增大，另一方面外‘與中軌之間接觸面積逐漸減 小又進一步增大了摩擦力，從而使滑動過程不順暢，且 使滑轨裝置更易損壞，影響滑軌的使用壽命。因此，如 何使滑轨裝置拉出過程達成中軌及内軌的依序拉出中， 及/、有内轨與中轨同步移動至中軌充分拉出外轨時，内 轨才可被拉出中轨，成為巫需解決的問題。 【發明内容】 雲於以上内容，有必要提供一種實現中轨及内轨的依序 拉出的滑轨裝置。 100100609 表單編號A0101 第5頁/共19頁 1002001098-0 [0005] 201230934 [0006] 一種滑執裝置，包括一外軌、一滑動收合於該外軌的中 軌、一滑動收合於該中軌的内執、一滑動穿設於該中執 的鎖止件及一安裝於該中軌的彈性件；該外軌設有一沿 滑軌裝置滑動方向延伸的支撐件及一靠近該支撐件前端 的固定部，該固定部包括一限位槽；該内軌設有一卡抵 部；該鎖止件設有一伸向該外軌的第一阻擔部及一伸向 該内軌的第二阻擋部；該外軌的支撐件支撐該鎖止件的 第一阻擋部而使該鎖止件保持於一鎖止位置時，該鎖止 件的第二阻擋部擋止該内軌的卡抵部，使該中軌與内軌 同步向前拉出外執，當該鎖止件隨中軌向前滑動至該鎖 止件的第一阻擋部滑過該支撐件而落入該外軌的限位元 槽時，該彈性件重定使該鎖止件滑至一解鎖位置，該鎖 止件的第二阻檔部脫離該内軌的卡抵部而使該内軌可滑 出該中軌。 [0007] 相較習知技術，所述滑軌裝置利用裝設於所述中執的鎖 止件滑行到鎖止位置時，該鎖止件的第二阻擋部擋止該 内軌的卡抵部，並且該外轨的支撐件支撐該鎖止件的第 一阻擋部而使該鎖止件保持於該鎖止位置，從而該中執 可隨内軌被同步向前拉出，直至該第一阻擋部對正該外 軌的限位槽而可令該鎖止件滑行到解鎖位置而解鎖該内 軌及該中軌，從而可進一步將内軌拉出中軌，從而實現 中轨及内軌的依序拉出，使滑動過程更加順暢，並提高 滑轨裝置使用壽命。 【實施方式】 [0008] 請參閱圖1，本發明滑軌裝置的較佳實施方式包括一外軌 100100609 表單編號A0101 第6頁/共19頁 1002001098-0 201230934 10、一可滑動收合於該外執10的中轨20、一可滑動收合 於該中執20的内軌30、一鎖止件40及一彈性件50。 [0009] 該外軌10包括一截面大致呈“C”形之長形的軌體11及一 固定於該軌體11的支撐件12。該軌體11包括一底壁及兩 相對之側壁。該底壁向内凸設一固定部11 2。該固定部 112大致成“凹”形，包括第一擋止端1121、第二擋止端 1123及設置於該第一、第二擋止端1121、1123之間的限 位槽1125。該支撐件12為長條體狀，在本實施方式中， θ 該支撐件12採用鉚合的方式固定於該軌體11的底壁的内 側並使其長度方向平行於該軌體11的滑動方向。該支撐 件12的頂緣設有一折邊。該支撐件12的前端鄰接該固定 部112的第一擋止端1121。在其他的實施方式中，該支撐 件12也可採用一體成型或者其他固定安裝方式安裝於該 軌體11。 [0010] 〇 該中執20為截面大致呈“C”形之長形體，其包括一底壁 及兩相對之側壁，該底壁靠近其後端處設有一大致與該 中軌20滑動方向垂直的滑槽22、一鄰近該滑槽22的卡固 部24、一鄰近該滑槽22的鉤扣孔26及一位於該滑槽22前 方的擋塊28。該滑槽22的上端形成導入口 221。 [0011] 該内軌30為截面大致呈“C”形之長形體，其包括一底壁 及兩相對之側壁，該底壁於鄰近後端處設有一向外凸出 的卡抵部32、一位於該卡抵部32前側並向外凸出的大致 呈扇形的解鎖部34。該卡抵部32及該解鎖部34分別靠近 該内軌30上、下兩側。該解鎖部34朝向該卡抵部32的一 侧形成一弧形的解鎖面341。 100100609 表單編號Α0101 第7頁/共19頁 1002001098-0 201230934 [0012] [0013] [0014] [0015] 100100609 凊參閱圖2，該鎖土件40包括一圓盤狀的本體41、自該本 體41其中一端面延伸的圓杈狀的第一阻擋部44及自該本 體41另一端面延伸的圓桎狀的第二阻擋部46。該第一阻 擔部44靠近該本體41處沿圓週表面設有一環形的第一卡 槽441。該第二I5且擋部46靠近該本體41處沿圓週表面設有 一環形的第二卡槽461。 在本實施方式中，該彈性件50為一彎折形成的概呈“V” 型的彈性金屬絲，其包括一第一彈性臂54及一第二彈性 臂56。該第一彈性臂54的末端形成一固持部541。該第二 彈性臂5 6的末端形成一卡韵561。 請參閱圖3，裝配時，將該鎖止件4〇的第一阻擋部44從該 中轨20的滑槽22的導入口 221置入該滑槽22内，使該滑 槽22的兩壁卡入該鎖止件4〇的第一卡槽441，該鎖止件 40的第一阻擋部44及第二阻擋部46分別位於該中軌2〇的 外側及内側。將該彈性件5〇的第一彈性臂54及第二彈性 臂56的中部卡固於該中轨2〇的卡固部24，該彈性件“的 第一彈性臂54的固持部541卡入該鎖止件40的第二卡槽 461，該彈性件5Q的卡鉤561卡入該中軌2〇的鉤扣孔26， 從而將該彈性件50安裳於該中軌2G。該彈性件5〇向下（ 遠離該滑槽22的導入〇221的方向）抵推該鎖止件4〇。 將該内軌30滑純合於中軌20。將該⑽3G及中軌2〇一 同收合於斜能，使該外㈣的讀件12的折邊抵靠 6玄鎖止件4〇的帛Ha擋部Μ，從而使該鎖止件“向該滑 槽22的上。h仃至一鎖止位置，並帶動該彈性件μ的第 一彈㈣54向㈣二彈性臂56擺動而使該彈性件5〇彈性 表單編號删丨 第8頁/共19頁 1002001098-0 201230934 變形。此時，該鎖止件40的第二阻擋部46位於該内軌3〇 的卡抵部32的前方並在該内轨3〇的滑動方向上對正該内 軌30的卡抵部32。 [0016] ❹ 〇 請同時參閱圖3及圖4,當向前（如箭頭D所示）杈出診内 軌30時，該内軌30相對該中轨2〇略微向前滑動便使誃内 軌30的卡抵部32卡擋於該鎖止件40的第二阻擋部46，於 是該中軌20與該内轨30保持同步向前滑動，而該鎖止件 40隨該中軌20向前滑動使該鎖止件4〇的第一阻擋部44 乂 該外軌10的支撐件12向該外軌1〇的固定部il2滑行。去 該鎖止件40的第一阻擋部44滑過該支撐件〗2的折邊及^ 固定部11 2的第一擋止端1121而落入正該固定部112的§限 位槽1125時，該中軌20的擋塊28擋止於該外軌1〇的固定 部112的第二擋止端1123，使中軌2〇不得繼續向前滑動^ 。該外軌10的固定部112的第一擋止端1121擋住該鎖止 件40的第^擋部44 ’防止該中執2〇向後縮回（如圖3至 5中的箭頭R所示），使中軌2〇定位於外軌1〇。同時，吞 彈性件50恢復變形而驅動華鎖止件4〇向該滑槽。的下= 滑動至-解鎖位置，使該第二阻播部46不再卡抵該内: 3〇的卡抵部32 ’從而可繼續向前拉動該内軌3q使該内軌 30滑出該中執20。 Λ [⑻ 17] 請參閱圖5 ’當向後（如箭則所示）推動該内執3〇而使 該内軌30逐漸收入該中軌20時，由於該鎖止件4〇的第— 阻擋部44落入該外軌1〇的固定部U2的限位槽^託，該 中執20定位於外軌1〇而不得向前或向後滑動。當該内2 30的解鎖部34滑行到該鎖止件4G的第二阻擒部^處時， 100100609 表單編號A0101 第9頁/共19頁 1002001098-0 201230934 該内軌30的卡抵部32已滑至該鎖止件40的後方，該解鎖 部34的解鎖面341沿該鎖止件40的第二阻擋部46向後滑 行使該鎖止件40向該滑槽22的上部滑行至鎖止位置，從 而使中軌20與外執10解鎖，同時，該内軌30完全收入中 軌20而被中軌20後端的擋止結構（圖未顯示）所擋住， 從而使中軌20與内軌30同步向後滑動而收入外軌10中。 [0018] 综上所述，本發明確已符合發明專利之要件，遂依法提 出專利申請。惟，以上所述者僅為本發明之較佳實施方 式，自不能以此限制本案之申請專利範圍。凡熟悉本案 技藝之人士爰依本發明之精神所作之等效修飾或變化， 皆應涵蓋於以下申請專利範圍内。 【圖式簡單說明】 [0019] 圖1係本發明滑軌裝置的較佳實施方式的立體分解圖。 [0020] 圖2係圖1中的鎖止件的放大圖。 [0021] 圖3至圖5係本發明滑軌裝置的較佳實施方式不同使用狀 態的示意圖。 【主要元件符號說明】 [0022] 外軌：10 [0023] 軌體：11 [0024] 固定部：11 2 [0025] 第一擋止端：1 1 21 [0026] 第二擋止端：1 1 23 [0027] 限位槽：1125 100100609 表單編號A0101 第10頁/共19頁 1002001098-0 201230934[0004] During the servo pull-out process, a force is generated between the force of the servo acting on the middle rail and the support force of the outer rail center rail.
