藉由上述結構組成設計,茲就本創作所揭可調式關門器之使用作動情形說明如下:如第10圖所示,當致動座41的受動端43連同凸輪44被既有門片(圖未繪示)所帶動時(如箭號L1所示),係可帶動致動座41朝圖中左側向移動(如箭號L2所示),藉此構成第一、第二活塞頭51、61於第一、第二缸室31、32中亦同步朝圖中左側向移動(如箭號L3所示)的狀態,此過程中,第一彈簧53和第二彈簧63會被壓縮(如箭號L4所示)而蓄積彈力;另一方 面,第一缸室31的空間體積隨著第一活塞頭51的位移而擴大過程中,作動槽33中的油液將會通過軸向貫穿孔54流過第一活塞頭51進入第一缸室31空間中(如箭號L5所示),而第二缸室32的空間體積隨著第二活塞頭61的位移而擴大過程中,作動槽33中的油液將會通過逆止閥64流過第二活塞頭61進入第二缸室32空間中(如箭號L6所示);且當致動座41移動至預定最大行程時,單側向配置式阻力流路單元70的常開式連通孔73、第一迴流旁通孔74、第二迴流旁通孔75與第二缸室32之間均呈連通狀態;接著如第11圖所示,係為可調式關門器進入自動關門階段的動作示意,此階段中,主要是利用第一、二彈簧53、63的彈力釋放作用,使第一、第二活塞頭51、61於第一、第二缸室31、32中係轉變為朝圖中右側向移動復位的狀態(如箭號L7所示);該第一、第二活塞頭51、61復位過程中,係可藉由單側向配置式阻力流路單元70的流路設計來達到減緩關門速度之目的,此請參第11圖所示,當該第一、第二活塞頭51、61往復位方向移動時,第一缸室31中的油液係通過軸向貫穿孔54回流至作動槽33(如箭號L8所示),而此時逆止閥64會呈逆止狀態,故第二缸室32中的油液無法通過逆止閥64到達作動槽33,第二缸室32中的一部份油液係通過常開式連通孔73回流至作動槽33(如箭號L9所示),第二缸室32中的另一部份油液則可通過第一、第二迴流旁通孔74、75的啟閉變化及第一、第二調節閥81、82的流量調節狀態來調控油液回流速度,此如第11圖所示,當第二活塞頭61往復位方向移動時,第一迴流旁通孔74會先被第二活塞頭61所遮擋阻斷,第二迴流旁通孔75及常開式連通孔73則保持開啟狀態,故此時第二缸室32中的油液能夠同時通過第二迴流旁通孔75及常開式連通孔73回流至作動槽33(註:此部份油液迴流路徑請配合參閱第6圖之箭號L10所示);隨著第二活塞頭61的繼續往復位移,會歷經一段第一、 第二迴流旁通孔74、75均被遮擋阻斷的過程,然後再到達第12圖所示僅第二迴流旁通孔75被遮擋阻斷的狀態;上揭第10至12圖的作動變化,由於油液的迴流路徑長短會改變,且配合該第一、第二調節閥81、82的預先流量調節,即可令可調式關門器使用上具有兩段式(如先快後慢)的功能與效果。With the above structural composition design, the operation of the adjustable door closer disclosed in the present application is explained as follows: As shown in Fig. 10, when the driven end 43 of the actuating seat 41 is combined with the cam 44 by the existing door (Fig. When not shown (as indicated by the arrow L1), the actuating seat 41 can be moved toward the left side in the figure (as indicated by the arrow L2), thereby forming the first and second piston heads 51, 61 is also synchronized in the first and second cylinder chambers 31, 32 to the left side of the figure (as indicated by arrow L3), during which the first spring 53 and the second spring 63 are compressed (eg, The arrow L4 shows) and the other side accumulates elasticity; the other side In the process of expanding the space volume of the first cylinder chamber 31 with the displacement of the first piston head 51, the oil in the actuation groove 33 will flow through the first piston head 51 through the axial through hole 54 into the first cylinder. In the space of the chamber 31 (as indicated by the arrow L5), and the space volume of the second cylinder chamber 32 is expanded in accordance with the displacement of the second piston head 61, the oil in the actuation groove 33 will pass through the check valve 64. Flowing through the second piston head 61 into the space of the second cylinder chamber 32 (as indicated by arrow L6); and when the actuator seat 41 is moved to the predetermined maximum stroke, the normally open one-way configuration resistance flow path unit 70 The communication hole 73, the first return bypass hole 74, the second return bypass hole 75 and the second cylinder chamber 32 are in a communicating state; then, as shown in FIG. 11, the adjustable door closer enters the automatic closing door. The action of the stage is illustrated. In this stage, the first and second piston heads 51, 61 are transformed in the first and second cylinder chambers 31 and 32 by utilizing the elastic releasing action of the first and second springs 53, 63. For the state of resetting to the right side in the figure (as indicated by arrow L7); during the resetting process of the first and second piston heads 51, 61, The flow path of the single laterally-disposed resistance flow path unit 70 is designed to achieve the purpose of slowing down the closing speed. Please refer to FIG. 11 , when the first and second piston heads 51 and 61 move in the reciprocating direction, The oil in the one cylinder chamber 31 is returned to the actuating groove 33 through the axial through hole 54 (as indicated by an arrow L8), and at this time, the check valve 64 is in a reverse state, so that the second cylinder chamber 32 The oil cannot pass through the check valve 64 to the actuating groove 33, and a part of the oil in the second cylinder chamber 32 is returned to the actuating groove 33 through the normally open communication hole 73 (as indicated by an arrow L9), the second cylinder Another portion of the oil in the chamber 32 can regulate the oil return flow rate through the opening and closing changes of the first and second return bypass holes 74, 75 and the flow regulating state of the first and second regulating valves 81, 82. As shown in FIG. 11, when the second piston head 61 moves in the reciprocating direction, the first recirculation bypass hole 74 is first blocked by the second piston head 61, and the second recirculation bypass hole 75 is often The open communication hole 73 is kept open, so that the oil in the second cylinder chamber 32 can be simultaneously returned to the second return bypass hole 75 and the normally open communication hole 73 to Groove 33 (Note: this part with fluid return path, please refer to the arrows of FIG. 6 LlO); continues with the reciprocating displacement of the second piston head 61, will over a period of a first, The second recirculation bypass holes 74, 75 are all blocked by the blocking process, and then reach the state in which only the second recirculation bypass hole 75 is blocked by the blockage shown in Fig. 12; the actuation changes of Figs. 10 to 12 are revealed. Since the length of the return path of the oil changes, and the pre-flow adjustment of the first and second regulating valves 81, 82 is matched, the adjustable door closer can be used in two stages (such as fast and slow).

功效說明:Efficacy description:
1、本創作藉由該單側向配置式阻力流路單元之技術特徵,本創作於第一、第二缸室中需開設的孔洞可精簡至僅三個,即常開式連通孔、第一迴流旁通孔及第二迴流旁通孔,且這三個孔洞僅由間隔壁連通至第二缸室,並未連通至第一缸室,故流道結構較習知簡單許多(註:習知須設五個通孔),俾可達到降低製造成本與不良率之優點。1. According to the technical features of the single lateral configuration resistance flow path unit, the holes to be opened in the first and second cylinder chambers can be reduced to only three, that is, normally open communication holes, A recirculation bypass hole and a second recirculation bypass hole, and the three holes are only connected to the second cylinder chamber by the partition wall, and are not connected to the first cylinder chamber, so the flow path structure is much simpler than the conventional one (Note: It is customary to have five through holes), which can achieve the advantages of reducing manufacturing costs and non-performing rates.
2、本創作藉由該第一活塞組的第一活塞頭設有軸向貫穿孔之技術特徵,構成第一活塞頭之軸向中央呈穿透型態,故其製造上無須採用實心胚料,僅須採用中空管料即可,俾可達到降低材料成本、製造成本之優點。2. The present invention is characterized in that the first piston head of the first piston set is provided with an axial through hole, and the axial center of the first piston head is formed in a penetrating manner, so that it is not required to use a solid billet in manufacturing. It is only necessary to use hollow pipe material, which can achieve the advantages of reducing material cost and manufacturing cost.
3、本創作之第二活塞頭的外周無須再二次加工形成習知結構所需的平切面18(參第1、3圖所示),俾可達到降低製造成本之優點。3. The outer circumference of the second piston head of the present invention does not need to be further processed to form the flat cut surface 18 required by the conventional structure (see FIGS. 1 and 3), and the advantage of reducing the manufacturing cost can be achieved.
