About the action of the automatic door closer. _ , ° month refer to the 4th, 4th, 5th, 6Α and 6Β图, firstly, please refer to the figure and the 6th figure. When the external force bows the door to open the door, the eccentric cam 3 2 will sweat y to push the second roller and drive the slide 2 1 to the front. At the same time, the slider 21 will push the abutting member 55 to compress the first elastic member Η and the second elastic member 52, and in addition, the top abutting member 55 is displaced. The hydraulic oil in the front chamber (1) is caused to flow into the 5th inlet port 13a of the first oil passage 13, and the hydraulic oil pressure system entering the first oil passage 13 makes the first The check valve μ is opened, and then the hydraulic oil system cuts the rear chamber 113 from the oil outlet m of the first oil passage 13 and pushes the cylindrical piston 4" to move in the direction of the intermediate chamber: otherwise, please refer to 4B and 6B, when the external force is released, the first elastic member 51 and the second elastic member 52 push the top abutting member 55 and the sliding seat 21, and push The eccentric cam 32 rotates. When the eccentric cam rotates, the first roller 22 is pushed up and the cylindrical piston 41 is driven to move in the direction of the cover 60. At this time, the hydraulic pressure in the rear cavity i丨3 The oil system will be pushed by the distal cylindrical piston 41 and flow into the second oil passage 15 to visit, & port 15a, and the hydraulic oil pressure entering the second oil passage 15 will cause the Chu_$ ~ The check valve 16 is opened, then the 'hydraulic oil system will flow from the second oil passage 1 5 < s Hai first - the outlet 15b and the second outlet 15c into the cylindrical piston 41 less 4 The passage 4 14 and the axial oil passage 4 1 3 are sequentially flowed into the intermediate face of the oil return hole 2 1 3 a of the side plate 2 13 of the sliding seat 2 1 and the back of the top portion 5 5 14 1345607 The oil passage 55d' is finally returned to the front m to close the door panel. In this embodiment, the hydraulic oil system first flows from the first outlet 15b of the nth 15 into the lateral oil groove of the cylindrical piston 41. 414 and the angle ^ 13 and as the cylindrical piston 41 gradually moves toward the cover 60, the first exit 〇 of the second oil passage 15 is closed, and at this time, the hydraulic oil is changed from the first The second "...flows into the lateral oil passage 414 of the cylindrical piston 41 and the axial oil passage 413, and further, in the present embodiment, when the hydraulic oil flows into the top abutment 55 The oil passage 55d' the third check valve 56 is opened to allow the hydraulic oil to smoothly flow back to the front chamber 111.
另外’因門板在關閉過程中其液壓油是慢慢回流至琴 前腔111，倘若門板在關閉過程中突然遭受—外力作用（如 踹門）’關門器可能因液壓油回流不及而損壞，因此，請再 參閱第4B及6B圖，在本實施例中，當門板在關閉過程中 突然遭受一外力作用時’該安全閥組件42之該安全閥423 係會快速開啟’以使位於該後腔11 3之液壓油直接流入該 套管422之該洩油孔道422a，並依序流經該中間腔1〖2、 該滑座21之該侧板213之該回油孔213a及該頂抵件55 之該回油通道5 5 d，最後快速回流至該前腔i丨丨，由於液 壓油可快速回流’因此，可防止關門器損壞，本發明係藉 由該滑座2 1與該筒狀活塞4 1之往復運動及該第一油路】3 與該第二油路15之作用而可提高自動關門器之運轉順暢 性。 本發明之保護範圍當視後附之申請專利範圍所界定 15 1345607 在不脫離本發明之精神和 1均屬於本發明之保護範 者為準’任何熟知此項技藝者， 範圍内所作之任何變化與修改 圍。 【圖式簡單說明】 第 1 圖：依據本發明之一較祛营#也丨 平乂佳貫靶例，—種自動 關門器之立體分解圓。 第 2 圖：該自動關門器之立體組合圖。In addition, because the hydraulic oil is slowly returning to the front chamber 111 during the closing process, if the door panel suddenly suffers during the closing process, the external force (such as the door) may be damaged due to the backflow of the hydraulic oil. Please refer to FIGS. 4B and 6B again. In this embodiment, when the door panel suddenly experiences an external force during the closing process, the safety valve 423 of the safety valve assembly 42 is quickly opened to be located in the rear cavity. The hydraulic oil of 11 3 directly flows into the oil drain hole 422a of the sleeve 422, and sequentially flows through the intermediate chamber 1 , 2 , the oil return hole 213 a of the side plate 213 of the slide 21 and the top member The oil return passage of 55 is 5 5 d, and finally returns to the front cavity i 快速 quickly, because the hydraulic oil can be quickly recirculated. Therefore, the door closer can be prevented from being damaged. The present invention is by the slide 2 1 and the cylindrical shape. The reciprocating motion of the piston 4 1 and the action of the first oil passage 3 and the second oil passage 15 can improve the smoothness of the operation of the automatic door closer. The scope of the present invention is defined by the scope of the appended claims, which are defined by the scope of the appended claims. With modification around.
