固定於連接件42之卡接塊427上，並將繞卷輪945之中心 A ^ 軸946端面略為方形之一端穿出前蓋板71之貫穿孔716 後與旋鈕97相卡合固定。 接著將定滑輪942之定位軸943之另一端***到擋板 75之轴孔753内，並將卷簧96之端轴962固定於擋板75 之二侧板752上，將套入壓縮彈簧98後之繞卷輪945之另 一端***到擋板75之定位孔754中。將二外導執76與擋 板75相互固定，最後將加強件74與擋板75固定並蓋上後 ^ 蓋板72及頂蓋板73，使前蓋板71、後蓋板72及頂蓋板 73相互扣合，從而形成升降機構30。 請參見圖4,轉動座40包括轉向件43、頂蓋45、底 蓋47及中蓋49。 該轉向件43包括底板437、彎折柱狀部432及球部 434。底板437與球部434分別位於彎折柱狀部432二端。 彎折柱狀部432之彎折處設有加強肋436，底板437由彎 折柱狀部432底端延伸而形成，該底板437上開設有若干 連接孔438，底板437藉由螺釘439與連接孔438相互配 13 200928168 合從而連接至連接件42。頂蓋45、中蓋49及底蓋47均設 有半球形凹槽，中蓋49及底蓋47構成之空間用於容納球 部434，中蓋49與頂蓋45間還設有彈片451，彈片451 分別抵持中蓋49與頂蓋45。底蓋47之一侧面向下延伸形 成一三角形連接部，連接部藉由螺釘474與安裝架50相連。 組裝轉動座40時，將轉向件43之球部434設於底蓋 47與中蓋49之間，並將頂蓋45、底蓋47及中蓋49扣合 併固定從而使球部434容納於頂蓋45及底蓋47相對側上 之半球形凹槽形成之容納空間内，從而構成一球運動副機 構。該球運動副機構可實現液晶顯示幕60之於任意方向之 旋轉及俯仰功能。該轉動座40與升降機構30共同組成一 調整機構（圖未標），該調整機構可實現液晶顯示幕60之 升降、旋轉及俯仰功能。 請同時參見圖2、圖3及圖6，當需降低液晶顯示幕 60之高度時，面對液晶顯示裝置100順時針方向轉動旋鈕 97，繞卷輪945隨之轉動，繩子944 一端進一步纏繞於繞 卷輪945上，而另一端從繞卷輪945上放鬆，從而使調節 架94 一側之繩子944連同定位塊949 一起下降，進而使與 定位塊949固定之連接件42連同轉動座40及液晶顯示幕 60下降。當需提升液晶顯示幕60之高度時，面對液晶顯 示裝置100逆時針轉動旋鈕97,使繞卷輪945轉動並帶動 繩子944連同連接件42上升，從而實現液晶顯示幕60之 上升，其工作原理與下降時相似。即，該調整機構可藉由 旋鈕97調整液晶顯示幕60之高度，操作極為方便，且該 200928168 動作藉由單手操作即可實現。 液晶顯示幕60停留於某一高度位置時，壓縮彈簧98 ' 具有預壓力，其朝前蓋板71推抵繞卷輪945,使前蓋板71 與繞卷輪945端面之間產生摩擦力防止繞轉輪945任意轉 動。於上述調整高度之過程中，於旋轉旋鈕97之同時朝後 推動旋鈕97，使繞卷輪945背離前蓋板71運動，從而消 除或減小前述摩擦力，使升降更輕鬆，此時，壓縮彈簧98 被進一步壓縮。停止調整液晶顯示幕60高度時，鬆開旋鈕 ® 97即可，壓縮彈簧98於其彈力作用下自動恢復並重新推 抵繞卷輪945。 當需調整液晶顯示幕60之左右或傾斜角度時，直接轉 動液晶顯示幕60即可，其可將液晶顯示幕60調整至任意 方向。 可以理解，該連接組件之定滑輪942、繩子944及繞 卷輪945可由其他機構代替，例如定滑輪942與繞卷輪945 0 由二鏈輪或二皮帶輪等其他轉動輪代替，繩子944由繞設 於鏈輪上之鏈條或繞設於皮帶輪上之皮帶等其他纏繞件代 替，只需繞設於二轉動輪上之纏繞件能於轉動輪之轉動下 相對轉動繞轉即可。 綜上所述，本發明符合發明專利要件，爰依法提出專 利申請。惟，以上所述者僅為本發明之較佳實施方式，本 發明之範圍並不以上述實施方式為限，舉凡熟悉本案技藝 之人士，於援依本案發明精神所作之等效修飾或變化，皆 應包含於以下之申請專利範圍内。 15 200928168 【圖式簡單說明】 圖1係一種習知調整機構立體分解圖。 圖2係應用本發明調整機構較佳實施方式之液晶顯示 裝置之侧視圖。 圖3係本發明調整機構較佳實施方式部分立體分解圖。 圖4係本發明調整機構較佳實施方式部分立體分解圖。 圖5係本發明調整機構較佳實施方式之連接組件主要 結構立體分解圖。It is fixed on the engaging block 427 of the connecting member 42 and passes through the through hole 716 of the front cover 71 at one end of the center of the winding wheel 945. Then, the other end of the positioning shaft 943 of the fixed pulley 942 is inserted into the shaft hole 753 of the baffle 75, and the end shaft 962 of the coil spring 96 is fixed to the two side plates 752 of the baffle 75, and the compression spring 98 is inserted. The other end of the subsequent winding reel 945 is inserted into the positioning hole 754 of the shutter 75. The two outer guides 76 and the baffle 75 are fixed to each other, and finally the reinforcing member 74 and the baffle 75 are fixed and the rear cover 72 and the top cover 73 are covered to make the front cover 71, the rear cover 72 and the top cover The plates 73 are engaged with each other to form the elevating mechanism 30. Referring to Fig. 4, the rotating base 40 includes a turning member 43, a top cover 45, a bottom cover 47, and a middle cover 49. The steering member 43 includes a bottom plate 437, a bent columnar portion 432, and a ball portion 434. The bottom plate 437 and the ball portion 434 are respectively located at both ends of the bent column portion 432. The bending portion of the bent columnar portion 432 is provided with a reinforcing rib 436. The bottom plate 437 is formed by extending from the bottom end of the bent columnar portion 432. The bottom plate 437 is provided with a plurality of connecting holes 438. The bottom plate 437 is connected by screws 439. The holes 438 are mated with each other 13 200928168 to be connected to the connector 42. The top cover 45, the middle cover 49 and the bottom cover 47 are each provided with a hemispherical groove, and the middle cover 49 and the bottom cover 47 form a space for accommodating the ball portion 434, and the elastic cover 451 is further disposed between the middle cover 49 and the top cover 45. The elastic piece 451 abuts the middle cover 49 and the top cover 45, respectively. One side of the bottom cover 47 extends downwardly to form a triangular connecting portion, and the connecting portion is connected to the mounting bracket 50 by screws 474. When the rotating base 40 is assembled, the ball portion 434 of the steering member 43 is disposed between the bottom cover 47 and the middle cover 49, and the top cover 45, the bottom cover 47 and the middle cover 49 are fastened and fixed so that the ball portion 434 is received at the top. The cover 45 and the hemispherical groove on the opposite side of the bottom cover 47 are formed in the accommodation space to constitute a ball motion auxiliary mechanism. The ball motion sub-mechanism can realize the rotation and tilting functions of the liquid crystal display screen 60 in any direction. The rotating base 40 and the lifting mechanism 30 together form an adjusting mechanism (not shown), which can realize the functions of lifting, rotating and tilting of the liquid crystal display screen 60. Referring to FIG. 2, FIG. 3 and FIG. 6, when the height of the liquid crystal display panel 60 needs to be lowered, the liquid crystal display device 100 is rotated clockwise to rotate the knob 97, and the winding reel 945 is rotated accordingly, and one end of the rope 944 is further wound around The winding wheel 945 is wound, and the other end is loosened from the winding reel 945, so that the rope 944 on one side of the adjusting frame 94 is lowered together with the positioning block 949, so that the connecting member 42 fixed to the positioning block 949 together with the rotating seat 40 and The liquid crystal display screen 60 is lowered. When the height of the liquid crystal display panel 60 needs to be raised, the liquid crystal display device 100 rotates the knob 97 counterclockwise to rotate the winding reel 945 and drive the rope 944 together with the connecting member 42 to rise, thereby realizing the rise of the liquid crystal display screen 60. The principle is similar to when it falls. That is, the adjustment mechanism can adjust the height of the liquid crystal display screen 60 by the knob 97, and the operation is extremely convenient, and the action of the 200928168 can be realized by one-hand operation. When the liquid crystal display screen 60 stays at a certain height position, the compression spring 98' has a pre-pressure which pushes against the winding reel 945 toward the front cover 71, thereby preventing friction between the front cover 71 and the end surface of the winding reel 945. The revolving wheel 945 is arbitrarily rotated. During the above adjustment of the height, the knob 97 is pushed backwards while rotating the knob 97, so that the winding reel 945 moves away from the front cover 71, thereby eliminating or reducing the aforementioned frictional force, making the lifting easier, at this time, compressing The spring 98 is further compressed. When you stop adjusting the height of the LCD screen 60, release the knob ® 97, and the compression spring 98 automatically recovers and re-pushes the winding reel 945 under its elastic force. When it is necessary to adjust the left and right or tilt angle of the liquid crystal display screen 60, the liquid crystal display screen 60 can be directly rotated, which can adjust the liquid crystal display screen 60 to any direction. It can be understood that the fixed pulley 942, the rope 944 and the winding reel 945 of the connecting component can be replaced by other mechanisms, for example, the fixed pulley 942 and the winding reel 945 0 are replaced by other rotating wheels such as two sprocket wheels or two pulleys, and the rope 944 is wound. Instead of other winding members such as a belt provided on the sprocket or a belt wound around the pulley, the winding member wound around the two rotating wheels can be rotated relative to the rotation of the rotating wheel.
