201018232 . 九、發明說明： 【發明所屬之技術領域】 ' 本發明涉及一種支撐裝置，尤其涉及一種用於支撐顯 示幕之支撐裝置。 【先前技術】 近年來，平板顯示器如液晶顯示器及電漿顯示器已經 被廣泛地用於個人電腦與電視之顯示器主體。為了減小包 ❹裝體積，亦便於將顯示器安裝於牆上或放置於桌上，此類 顯示器之顯示幕與支撐底座通常設計為分離式結構。 請參閱圖1，一種顯示器10包括顯示幕11、支撐座12、 滑動機構13及定位機構14。顯示幕11之背面112具有第 一安裝部114，支撐座12之頂端具有第二安裝部122。滑 動機構13包括一對滑槽132及一對滑塊134,其中滑槽132 設於第一安裝部114上，而滑塊134設於第二安裝部122 上。定位機構14包括彈性卡塊142與限位開口 144。彈性 ©卡塊142設於顯示幕11之背面112之凹槽（圖未示）内，並 可於該凹槽内來回移動。限位開口 144設於支撐座12之第 二安裝部122，彈性卡塊142可卡合於限位開口 144中，用 以擋止第一安裝部114與第二安裝部122之間相對滑動。 當需將顯示幕11安裝至支撐座12時，首先對彈性卡 塊142施加壓力，使彈性卡塊142完全進入凹槽内，然後 使支撐座12之第二安裝部122通過滑槽132及滑塊134嵌 入顯示幕10之第一安裝部114。當第二安裝部122上之限 201018232 • 位開口 144剛好移動至彈性卡塊142之上方時，彈性卡塊 142於回彈力之作用下而卡入限位開口 144内，從而將顯示 幕11與支撐座12固定。當需拆卸該顯示器10時，同樣需 對彈性卡塊142施加壓力，使彈性卡塊142進入凹槽内而 不受限位開口 144之限制，如此，支撐座12之第二安裝部 122可與顯示幕11之第一安裝部114分離。 然，由於顯示器10之整個重量全部由卡入限位元開口 144之彈性卡塊142來支撐，因此當拆卸上述顯示器10之 ❿過程中，需對彈性卡塊142施加很大之壓力以克服限位元 開口 144與彈性卡塊142之間較大之摩擦力，較為不便。 另一方面，由於彈性卡塊142與限位開口 144之間之摩擦 力較大，多次裝拆後有可能導致彈性卡塊142磨損，因此 這種顯示器10之支撐裝置之使用壽命不高。 【發明内容】 有鑒於此，有必要提供一種拆卸較為方便，使用壽命 ®較高之支撐裝置。 一種支撐裝置，包括支撐主體及與被支撐物相連之插 接件。支撐主體上設有容納插接件之安裝孔及與安裝孔相 配合之鎖固機構。插接件可沿第一方向插入或拔出安裝 孔，鎖固機構包括可沿與第一方向相交之第二方向伸縮之 凸柱。插接件上開設有可容納凸柱之鎖定孔。插接件容納 於安裝孔時，鎖固機構驅動凸柱進入鎖定孔從而限制插接 件沿第一方向脫離安裝孔。 8 201018232 ' 使用該支撐裝置以後，被支撐物之重量主要由安裝孔 .與插接件來承受，凸柱與鎖定孔之間之相對作用力較小， 因此調節該Λ柱之位置時較為輕鬆方便。而且由於凸柱於 插接件之鎖定孔内移動時其相互摩擦較小，不易磨損，故 該支撐裝置之使用壽命較高。 【實施方式】 下面將結合附圖及實施方式對本發明之支撐裝置作進 ❹一步之詳細說明。 本發明之實施方式公開一種支撑裝置，其用於支撐帶 有顯不幕之電子裝置。於本實施方式中’以應用於液晶顯 示器之支撐裝置為例加以說明。 請一併參閱圖2與圖3。本發明實施方式之支撐裝置 應包括支撐主體20及與支標主體20相連之錢4〇、鎖 固機構50、插接件60、第一殼體81與第二殼體82。 支撐主體2G大致為柱狀’其側壁上卩^有沿第—方向延 伸之安裝孔。於本實施方式中，第一方向為水平方向。 底座40大致為圓盤狀，其表面設有定位部41。支撐主體 20通過定位部41固定於底座4〇上。當支揮主體之下部 之形狀時’底座4〇亦可省卻。鎖固機構50設 ==20广頂部。插接件6〇大致為長條塊狀，其包 括插接邛61、連接件63、鎖定孔65與鉸 加 部分插接於支撐主體20之安裝孔21内 ° .L ^ ^孔21内。鎖定孔65開設於 插接川上。鉸鏈67穿過連接件63，並與—液晶顯示幕（圖 9 201018232 * 未示）相連，以使液晶顯示幕可改變其俯仰角度。可理解， 鉸鏈67亦可省卻。第一殼體81與第二殼體82用於包覆於 ·* 支撐主體20與鎖固機構50之外部，主要起裝飾作用，二 者皆可省卻。 請參閱圖4，支撐主體20之頂部沿第二方向開設有用 於安裝鎖固機構50之安裝槽23。於本實施方式中，第二方 向為與第一方向相交之垂直方向。安裝槽23之截面形狀為 橢圓形，其底面開設有圓形容納孔231與位於容納孔231 ❿兩側之二螺紋孔233。容納孔231與安裝孔21相通，容納 孔231之末端還設有一縮口部235(見圖14)。二螺紋孔233 分別位於容納孔231之兩側。 該鎖固機構50包括按鈕51、主動件52、從動件53、 限位元件54、彈性件55與螺釘56。 按鈕51為具有一底壁之中空之圓柱體。 主動件52大致為圓枉狀，其一端形成有台階部521。 台階部521之端面上沿軸向設有複數第一棘輪齒523。台階 ❹部521外周面上設有三等間距之第一導柱5211。 從動件53包括圓柱狀凸柱531與凸柱531中部延伸形 成之凸緣部533。凸柱531下端可穿過容納孔231而進入安 裝孔21内。凸緣部533之頂端設有用於與主動件52之第 一棘輪齒521相嚙合之第二棘輪齒5331。凸緣部533之外 周面上還設有三等間距之第二導柱5333。第二導柱5333 之寬度與第一導住5211之寬度相同，第二導柱5333之頂 端形成有第一斜面5335。 201018232 * 限位件54包括圓柱狀主體541及其一端延伸形成之截 面為橢圓之連接部543。連接部543容置於支撐主體20之 安裝槽23内’且主體541容置於容納孔231内。連接部543 中部開設有貫通限位件54之圓形貫通孔545。貫通孔545 兩側還分別設有二通孔547。請一併參閱圖5與圖6，限位 件54之貫通孔545之内表面還設有引導部546。引導部546 為二組’其申，每一組包括沿第二方向延伸之依次相鄰之 第一引導槽5461、第一引導凸起5463、第二引導槽5465 ❹與第二引導凸起5467。第一引導槽5461係用於引導第一導 柱5211與第二導柱5333於其内沿第二方向滑動。第一引 導凸起5463之底端形成有與第二導柱5333之第一斜面 5335相配合之第二斜面5462。第二引導凸起5467與第一 引導凸起5463形狀相同，其底端具有第三斜面5466。第二 引導槽5465位於第一引導凸起5463與第二引導凸起5467 之間，其底端形成有可與第二導柱5333之第一斜面5335 相配合之擋止部5464。擋止部5464相比第二斜面5462與 ❹第三斜面5466更接近於貫通孔545之頂端。第二引導槽 5465之長度tb第一引導槽5461小，故當第二導柱5333於 第一引導槽5461内及與擋止部5464相抵持之二位置切換 時，從動件53相對於限位件54之位置會有相應變化。 彈性件55為套設於從動件53之凸柱531上之壓縮彈 簧，其一端與從動件53之凸緣部533相抵，另一端與支撑 主體20之縮口部235之頂面相抵。 ” 螺釘56用以穿過通孔547及螺紋孔233以將限位件54 11 201018232 - 固定於支撐主體20之安裝槽23内。 裝配鎖固機構50時，首先彈性件55置於支撐主體20 之容納孔231内，並停留於縮口部235上，然後從動件53 之凸柱531插入彈性件55中，主動件52置於從動件53上 方並使第一棘輪齒523與第二棘輪齒5331相接觸，再將限 位件54套設於主動件52與從動件53之外部，並用螺釘56 將限位件54固定於安裝槽23内，最後按鈕51固定地套設 於主動件52上，以便於按壓主動件52。 ❹ 為了更好地說明主動件52、從動件53及限位件54之 間之運動及配合關係，請一併參閱圖7至圖13。圖7至圖 13係主動件52之第一棘輪齒523、從動件53之第二棘輪 齒5331及限位件54之引導部546沿其周向展開後之示意 圖。為便於理解，圖7至圖13中僅顯示了一第一導柱5211 與一第二導柱5333,其餘二第一導柱5211與第二導柱5333 之動作相同。 圖7為鎖固機構50處於解鎖狀態之示意圖，解鎖狀態 ®係從動件53之凸柱531未插入插接件60之鎖定孔65内之 狀態，即插接件60可從支撐主體20内拔出來之狀態。於 解鎖狀態下，主動件52與從動件53於彈性件55之作用下 固定於鄰近貫通孔545頂端之位置，此時從動件53之凸柱 531全部收容於限位元件54之貫通孔545内，且主動件52 之第一導柱5211與從動件53之第二導柱5333 —併容置於 引導部546之第一引導槽5461内。於該狀態下，第一棘輪 齒523與第二棘輪齒5331以一種不穩定之方式結合，即第 12 201018232 .一棘輪齒523之齒頂部處於第二棘輪齒5331之齒根部與齒 頂部之間之位置，但由於第一導柱5211與第二導柱5333 一併位於第一引導槽5461内，故主動件52與從動件53此 時不會發生相對轉動而保持穩定。 如圖8所示，當對按鈕51向下施加壓力以克服彈性件 55之彈力而推動主動件52向下移動時，從動件53會隨主 動件52 —起於向下移動，使第二導柱5333到達鄰近第一 引導凸起5463之最末端之位置。期間，由於從動件53之 ❹第二導柱5333始終容置於第一引導槽5461内，故從動件 53繞自身之軸旋轉之趨勢被限止，從動件53與主動件52 之間之相對位置關係保持不變。 如圖9所示，當對主動件52繼續施加壓力時，第二導 柱5333會從引導槽5461中完全退出，此時，從動件53繞 自身之軸旋轉之限止被解除。於第一棘輪齒523之作用下， 從動件53會繞自身之軸線旋轉一定角度而使第二棘輪齒 5331與主動件52之第一棘輪齒523完全嚙合。嚙合後，主 ®動件52與從動件53以一種較為穩定之結合方式一起下降 至按壓行程末端位置。 圖10為鎖固機構50處於鎖合狀態之示意圖，鎖合狀 態為從動件53之凸柱531已插入插接件60之鎖定孔65内 之狀態，此時凸柱531將插接件60與支撐主體20鎖固於 一起。如圖10所示，當於圖9所示之按壓行程末端解除對 主動件52之按壓力時，於彈性件55之回彈作用下，主動 件52與從動件53會一併上升。當第二導柱5333與第一引 13 201018232 - 導凸起5463相接觸時，第二導柱5333之第一斜面5335會 於第一引導凸起5463之第二斜面5462之引導作用下向右 移動，使得從動件53繼續旋轉一定角度。由於主動件52 之第一導柱5211始終位於第一引導槽5461内，故主動件 52無法旋轉。主動件52與從動件53之間之相對運動導致 第一棘輪齒523與第二棘輪齒5331不再完全嚙合而以一種 與圖7相似之不穩定結合狀態一同上升。由於第二引導凹 槽5465之擂止部5464相比第二斜面5462更接近於貫通孔 ❹545之頂端，故當從動件53上升至某一位置時，第二導柱 5333會自動進入第二引導凹槽5465内，並使得第二導柱 5333之第一斜面5335與擋止部5464相抵持。此時，與解 鎖狀態相比，從動件53穩定於更加鄰近限位件54之貫通 孔545底部之位置，且從動件53之凸柱531部分凸出於貫 通孔545之外。 如圖11所示，當再次對主動件52施加向下之壓力推 動主動件52向下運動時，從動件53之第二導柱5333會於 ®第二引導凹槽5465内隨主動件52 —起向下移動而與擋止 部5464分離。移動至一定位置時，第二導柱5333到達鄰 近第三引導凸起5467之最末端之位置。 如圖12所示，繼續對主動件52施加壓力，第二導柱 5333會從第二引導槽5465中完全退出，此時，從動件53 繞自身之軸旋轉之限止被解除。於第一棘輪齒523之作用 下，從動件53會旋轉一定角度而使第二棘輪齒5331與第 一棘輪齒523再次完全嚙合。喃合後，主動件52與從動件 201018232 -53以一種較為穩定之結合方式一起下降至按壓行程末端位 置。 圖13係鎖固機構50重新回復至解鎖狀態之示意圖。 如圖13所示，當於圖12所示之按壓行程末端解除對主動 件52之按壓力時，於彈性件55之回彈作用下，主動件52 與從動件53會一併上升。當第二導柱5333與第二引導凸 起5467相接觸時，第二導柱5333之第一斜面5335會於第 二引導凸起5467之第三斜面5466之引導作用下向右移 ❹動，使得從動件53繼續旋轉一定角度而逐漸進入下一第一 引導凹槽5461中。主動件52與從動件53之間之相對運動 導致第一棘輪齒523與第二棘輪齒5331不再完全嚙合而以 不穩定之結合狀態一同上升。上升至最頂端後，從動件53 之凸柱531再次全部收容於限位元件54之貫通孔545内。 請一併參閱圖14至圖15。當需將液晶顯示幕安裝至本 支撐裝置100時，首先使鎖固機構50處於解鎖狀態，再將 插接件60之插接部61插入安裝孔21内，並使鎖定孔65 ®對準支撐主體20之容納孔231;此時插接件60除了於安裝 孔21内滑動外，無法沿其他方向運動；然後對鎖固機構50 之按鈕51施加向下之壓力，使鎖固機構50從解鎖狀態轉 變為鎖固狀態並驅動從動件53之凸柱531穿過容納孔231 而進入且穩固於插接件60之鎖定孔65内，即如圖10所示 狀態；這時，插接件60無法於安裝孔21内滑動，由此將 液晶顯示幕與支撐主體20固定於一起。 當需將液晶顯示幕從支撐裝置100上拆卸下來時，僅 15 201018232 需再次對按纽51施加向下夕殿 门下之壓力，使鎖固機構50從鎖固 狀態回復為如圖7戎圖於- 次圖13所不之解鎖狀態；此時，凸柱531 向上運動而從鎖定孔65内蒋屮你址从 〜移出，插接件60可從安裝孔21 中移出而與支撐主體2〇分離。 4 使用月實_施方式之支擇裝f 100時，僅需下壓按 紐5ί即可實現顯示幕之安裝與拆卸整個過程方便快捷。 由於液晶顯示器之重量主要靠安裝孔21與插接件6〇來支 ❹ 撐，凸柱531與鎖定孔65之間之相對作用力較小，相對移 動f產生之摩擦力較小，不易磨損，故支撐裝置通之使 用哥命較高。 可理解，鎖固機構50亦可不設於支撐主體20之頂面 上’而是設於與第-方向相交之另_水平方向上例如與 安裝孔21相鄰之-側面上。鎖固機構％亦可不採取本發 明實施方式所描述之結構，例如採用電磁閥、氣缸等可驅 動從動件53來回運動以使其凸& 531插人並鎖固或抽出插 接件60之鎖定孔65之結構。 絲上所述’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。舉凡熟悉本案 技藝之人士援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】 圖1係一種支撐裝置之分解圖。 圖2係本發明實施方式之支撐裝置之組裝圖。 16 201018232 -

IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a supporting device, and more particularly to a supporting device for supporting a display screen. [Prior Art] In recent years, flat panel displays such as liquid crystal displays and plasma displays have been widely used for display main bodies of personal computers and televisions. In order to reduce the size of the package, it is also convenient to mount the display on a wall or on a table. The display screen and the support base of such a display are usually designed as a separate structure. Referring to FIG. 1 , a display 10 includes a display screen 11 , a support base 12 , a sliding mechanism 13 , and a positioning mechanism 14 . The back surface 112 of the display screen 11 has a first mounting portion 114, and the top end of the support base 12 has a second mounting portion 122. The sliding mechanism 13 includes a pair of sliding slots 132 and a pair of sliders 134. The sliding slots 132 are disposed on the first mounting portion 114, and the slider 134 is disposed on the second mounting portion 122. The positioning mechanism 14 includes a resilient block 142 and a limit opening 144. The resilient member 142 is disposed in a recess (not shown) of the back surface 112 of the display screen 11 and is movable back and forth within the recess. The limiting opening 144 is disposed on the second mounting portion 122 of the support base 12, and the elastic blocking block 142 can be engaged with the limiting opening 144 to block the relative sliding between the first mounting portion 114 and the second mounting portion 122. When the display screen 11 needs to be mounted to the support base 12, pressure is first applied to the elastic block 142, so that the elastic block 142 completely enters the groove, and then the second mounting portion 122 of the support base 12 passes through the chute 132 and slides. Block 134 is embedded in first mounting portion 114 of display screen 10. When the limit of the second mounting portion 122 is 201018232, the positional opening 144 just moves over the elastic block 142, the elastic block 142 is snapped into the limiting opening 144 by the resilience force, thereby the display screen 11 and The support base 12 is fixed. When the display 10 needs to be disassembled, pressure is also applied to the elastic block 142 to allow the elastic block 142 to enter the groove without restricting the opening 144. Thus, the second mounting portion 122 of the support base 12 can be The first mounting portion 114 of the display screen 11 is separated. However, since the entire weight of the display 10 is supported by the elastic block 142 that is inserted into the limit opening 144, during the process of disassembling the display 10, a large pressure is applied to the elastic block 142 to overcome the limit. The large friction between the bit opening 144 and the elastic block 142 is inconvenient. On the other hand, since the friction between the elastic block 142 and the limiting opening 144 is large, the elastic block 142 may be worn after repeated assembly and disassembly, so the service life of the support device of the display 10 is not high. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a support device that is more convenient to disassemble and has a longer service life. A support device includes a support body and a connector connected to the supported object. The support body is provided with a mounting hole for receiving the connector and a locking mechanism for cooperating with the mounting hole. The connector can be inserted into or withdrawn from the mounting hole in a first direction, and the locking mechanism includes a post that can be telescoped in a second direction that intersects the first direction. A locking hole for accommodating the stud is opened on the connector. When the connector is received in the mounting hole, the locking mechanism drives the stud into the locking hole to restrict the connector from being disengaged from the mounting hole in the first direction. 8 201018232 ' After using this support device, the weight of the supported object is mainly supported by the mounting hole and the connector. The relative force between the stud and the locking hole is small, so it is easier to adjust the position of the mast. Convenience. Moreover, since the studs are less rubbed against each other when moving in the locking holes of the connector, they are less prone to wear, so the service life of the supporting device is higher. [Embodiment] Hereinafter, the supporting device of the present invention will be further described in detail with reference to the accompanying drawings and embodiments.

Referring to FIG. 5 and FIG. 6, the inner surface of the through hole 545 of the limiting member 54 is further provided with a guiding portion 546. The guiding portion 546 is a group of two, each of which includes a first guiding groove 5461, a first guiding protrusion 5463, a second guiding groove 5465 ❹ and a second guiding protrusion 5467 which are sequentially adjacent in the second direction. . The first guiding groove 5461 is for guiding the first guide post 5211 and the second guide post 5333 to slide in the second direction therein. The bottom end of the first guiding protrusion 5463 is formed with a second inclined surface 5462 which cooperates with the first inclined surface 5335 of the second guiding post 5333. The second guiding projection 5467 has the same shape as the first guiding projection 5463, and has a third inclined surface 5466 at its bottom end. The second guiding groove 5465 is located between the first guiding protrusion 5463 and the second guiding protrusion 5467, and the bottom end thereof is formed with a stopping portion 5464 which can cooperate with the first inclined surface 5335 of the second guiding post 5333. The stopper portion 5464 is closer to the tip end of the through hole 545 than the second slope 5462 and the third slope 5466. The length of the second guiding groove 5465 is smaller than the first guiding groove 5461. Therefore, when the second guiding post 5333 is switched between the first guiding groove 5461 and the blocking portion 5464, the follower 53 is opposite to the limit. The position of the bit member 54 will change accordingly. The elastic member 55 is a compression spring that is sleeved on the boss 531 of the follower 53 and has one end that abuts against the flange portion 533 of the follower 53 and the other end that abuts against the top surface of the neck portion 235 of the support body 20. The screw 56 is used to pass through the through hole 547 and the threaded hole 233 to fix the limiting member 54 11 201018232 - in the mounting groove 23 of the supporting body 20. When the locking mechanism 50 is assembled, the elastic member 55 is first placed on the supporting body 20 The receiving hole 231 is received in the hole 235, and then the protruding post 531 of the follower 53 is inserted into the elastic member 55. The driving member 52 is placed above the follower 53 and the first ratchet tooth 523 and the second The ratchet teeth 5331 are in contact with each other, and the limiting member 54 is sleeved on the outside of the driving member 52 and the driven member 53, and the limiting member 54 is fixed in the mounting groove 23 by the screw 56, and finally the button 51 is fixedly set on the active side. The member 52 is arranged to facilitate pressing of the driving member 52. ❹ In order to better illustrate the movement and cooperation between the driving member 52, the follower member 53 and the limiting member 54, please refer to FIG. 7 to FIG. 13 is a schematic view of the first ratchet teeth 523 of the driving member 52, the second ratchet teeth 5331 of the follower 53 and the guiding portion 546 of the limiting member 54 along the circumferential direction thereof. For ease of understanding, FIG. 7 to FIG. Only one first guide post 5211 and one second guide post 5333 are shown in FIG. 13, and the other two first guide posts 5211 and second guide post 5333 are shown. The action is the same. Fig. 7 is a schematic view showing the locking mechanism 50 in an unlocked state, in which the unlocking state о is the state in which the boss 531 of the follower 53 is not inserted into the locking hole 65 of the connector 60, that is, the connector 60 can be supported from the support. The main body 20 is pulled out. In the unlocked state, the driving member 52 and the follower 53 are fixed to the top of the through hole 545 by the elastic member 55. At this time, the protruding post 531 of the follower 53 is all. The first guide post 5211 of the active member 52 and the second guide post 5333 of the follower 53 are received in the first guiding groove 5461 of the guiding portion 546. In this state, the first ratchet teeth 523 and the second ratchet teeth 5331 are combined in an unstable manner, that is, 12th 201018232. The tooth top of a ratchet tooth 523 is between the root of the second ratchet tooth 5331 and the top of the tooth. Position, but since the first guide post 5211 and the second guide post 5333 are located together in the first guiding groove 5461, the active member 52 and the follower 53 are not rotated relative to each other and remain stable as shown in FIG. When the button 51 is pressed downward to push against the elastic force of the elastic member 55 When the driving member 52 moves downward, the follower 53 will move downward with the driving member 52, so that the second guiding post 5333 reaches the position adjacent to the extreme end of the first guiding protrusion 5463. During the period, due to the follower After the second guide post 5333 is always accommodated in the first guiding groove 5461, the tendency of the follower 53 to rotate about its own axis is limited, and the relative positional relationship between the follower 53 and the active member 52 remains unchanged. As shown in Fig. 9, when the pressure is continuously applied to the driving member 52, the second guiding post 5333 is completely withdrawn from the guiding groove 5461, and at this time, the restriction of the rotation of the follower 53 about its own axis is released. Under the action of the first ratchet teeth 523, the follower 53 is rotated about its own axis to cause the second ratchet teeth 5331 to fully mesh with the first ratchet teeth 523 of the active member 52. After the engagement, the main actuator 52 and the follower 53 are lowered together in a relatively stable manner to the end position of the pressing stroke. FIG. 10 is a schematic view showing the locking mechanism 50 in a locked state. The locking state is a state in which the protruding post 531 of the follower 53 has been inserted into the locking hole 65 of the connector 60. At this time, the stud 531 will be the connector 60. It is locked with the support body 20. As shown in Fig. 10, when the pressing force of the driving member 52 is released at the end of the pressing stroke shown in Fig. 9, the active member 52 and the follower 53 are raised together by the rebound of the elastic member 55. When the second guiding post 5333 is in contact with the first guiding 13 201018232 - guiding protrusion 5463, the first inclined surface 5335 of the second guiding post 5333 will be directed to the right under the guiding of the second inclined surface 5462 of the first guiding protrusion 5463. The movement causes the follower 53 to continue to rotate by a certain angle. Since the first guide post 5211 of the active member 52 is always located within the first guide groove 5461, the active member 52 cannot be rotated. The relative movement between the active member 52 and the follower 53 causes the first ratchet teeth 523 and the second ratchet teeth 5331 to no longer fully engage and rise together in an unstable combined state similar to that of Figure 7. Since the locking portion 5464 of the second guiding groove 5465 is closer to the top end of the through hole 545 than the second inclined surface 5462, when the follower 53 is raised to a certain position, the second guiding post 5333 automatically enters the second position. The groove 5465 is guided, and the first slope 5335 of the second pillar 5333 is abutted against the stopper 5464. At this time, the follower 53 is stabilized at a position closer to the bottom of the through hole 545 of the stopper 54 than the unlocked state, and the portion of the boss 531 of the follower 53 protrudes beyond the through hole 545. As shown in FIG. 11, when the downward pressure is applied to the driving member 52 to push the driving member 52 downward, the second guiding post 5333 of the follower 53 will follow the active member 52 in the second guiding groove 5465. The movement is downward and separated from the stopper 5464. When moving to a certain position, the second guide post 5333 reaches a position adjacent to the extreme end of the third guiding projection 5467. As shown in Fig. 12, pressure is applied to the driving member 52, and the second guide post 5333 is completely withdrawn from the second guiding groove 5465. At this time, the restriction of the rotation of the follower 53 about its own axis is released. Under the action of the first ratchet teeth 523, the follower 53 is rotated by a certain angle to completely engage the second ratchet teeth 5331 and the first ratchet teeth 523 again. After the merging, the active member 52 and the follower 201018232-53 are lowered together to a position at the end of the pressing stroke in a relatively stable manner. Figure 13 is a schematic illustration of the locking mechanism 50 returning to the unlocked state. As shown in Fig. 13, when the pressing force of the driving member 52 is released at the end of the pressing stroke shown in Fig. 12, the active member 52 and the follower 53 are raised together by the rebound of the elastic member 55. When the second guiding post 5333 is in contact with the second guiding protrusion 5467, the first inclined surface 5335 of the second guiding post 5333 is moved to the right by the guiding of the third inclined surface 5466 of the second guiding protrusion 5467. The follower 53 is caused to continue to rotate by a certain angle to gradually enter the next first guiding groove 5461. The relative movement between the active member 52 and the follower 53 causes the first ratchet teeth 523 and the second ratchet teeth 5331 to no longer fully engage and rise together in an unstable combined state. After rising to the top end, the boss 531 of the follower 53 is again accommodated in the through hole 545 of the limiting member 54. Please refer to Figure 14 to Figure 15 together. When the liquid crystal display screen is to be mounted to the support device 100, the locking mechanism 50 is first unlocked, and the plug portion 61 of the connector 60 is inserted into the mounting hole 21, and the locking hole 65 is aligned with the support. The receiving hole 231 of the main body 20; at this time, the plug 60 can not move in other directions except for sliding in the mounting hole 21; then, the downward pressure is applied to the button 51 of the locking mechanism 50, so that the locking mechanism 50 is unlocked. The state transitions to the locked state and drives the boss 531 of the follower 53 through the receiving hole 231 to enter and be secured in the locking hole 65 of the connector 60, that is, as shown in FIG. 10; at this time, the connector 60 It is impossible to slide inside the mounting hole 21, thereby fixing the liquid crystal display panel and the support main body 20. When the liquid crystal display screen needs to be detached from the supporting device 100, only 15 201018232 needs to apply the pressure under the lower ceremonial door to the button 51 again, so that the locking mechanism 50 returns from the locked state to the figure as shown in FIG. - the unlocking state of Fig. 13; at this time, the stud 531 moves upward to be removed from the locking hole 65, and the connector 60 can be removed from the mounting hole 21 to be separated from the supporting main body 2 . 4 When using the monthly real_ application mode to install f 100, you only need to press the button 5 to realize the installation and disassembly of the display screen is convenient and quick. Since the weight of the liquid crystal display is mainly supported by the mounting hole 21 and the connector 6〇, the relative force between the protruding post 531 and the locking hole 65 is small, and the relative movement f generates less friction and is less prone to wear. Therefore, the use of the support device is higher. It can be understood that the locking mechanism 50 may not be disposed on the top surface of the support body 20, but may be disposed on the side surface adjacent to the mounting hole 21 in the other horizontal direction intersecting the first direction. The locking mechanism % may also not adopt the structure described in the embodiment of the present invention, for example, a solenoid valve, a cylinder, or the like may be used to drive the follower 53 to move back and forth to insert the male < 531 and lock or withdraw the connector 60. The structure of the locking hole 65. As stated on the silk, the invention has indeed met the requirements of the invention patent and has filed a patent application in accordance with the law.
