【物品用途】;本物品係一種流體壓力缸，可在從一組壓力流體導出導入通口供給之壓力流體的作用下推壓收納在缸管內之活塞，使連結在活塞之活塞桿做直線狀之往復動作。;在使用之際，將壓力流體交互地供給至壓力流體導出導入通口，使缸管內部之活塞前進後退。藉此，活塞桿會沿著缸管之軸線方向做直線狀之往復動作。;供給至頭罩側之缸室之壓力流體係在推壓活塞之頭罩側而使活塞桿伸長後，從排氣返回通口經由未圖示之電磁閥及連通至桿罩側之缸室的壓力流體導出導入通口從流入至桿罩側之缸室，再度利用於推壓活塞之桿罩側而將活塞桿拉入至缸管內之工作。;【設計說明】;本設計係關於第108300695號專利申請案之衍生設計。;本設計物品之流體壓力缸係具有：缸管；設置在缸管之一端的頭罩；設置在缸管之另一端的桿罩；與缸管之軸線平行地延伸，且連結頭罩及桿罩之四根繋桿；從桿罩突出之活塞桿；以及安裝在活塞桿之前端的螺帽(參照顯示各部名稱之參考立體圖1及顯示各部名稱之參考立體圖2)。;缸管係整體呈大致圓筒形狀，且在缸管之內部設置有缸室。在缸室收納有未圖示之活塞，且在該活塞連結有活塞桿。;如省略內部機構之A-A線剖面圖所示，位於缸管之外周附近且與一根繋桿平行之剖面呈大致半圓形狀之膨出部係沿著長度方向延伸。在該膨出部之內側設置有在由活塞所區隔出之桿罩側的缸室與頭罩側的缸室之間讓壓力流體可逆地通過的流路。;頭罩及桿罩係呈大致長方體狀，並且，一方面在頭罩沿著缸管之軸線方向形成有薄且呈圓形狀之突部，另一方面在桿罩具備有沿著缸管之軸線方向膨出之厚的圓筒部。;在桿罩之一面設置有：與桿罩側之缸室連通之壓力流體導出導入通口；與頭罩側之缸室連通之壓力流體導出導入通口；排氣返回通口，用以使頭罩側之缸室的壓力流體經由未圖示之電磁閥返回進入至桿罩側之缸室；以及節流閥，用以調整往缸管之外部進行排氣的壓力流體之流量。;在桿罩之一面設置有緩衝針。在頭罩及桿罩之剩餘的三面設置有相同形狀且寬之溝部。;本創作之特徵係在於「流體壓力缸」之整體形狀。[Use of the item]; This item is a fluid pressure cylinder that can push the piston contained in the cylinder tube under the action of the pressure fluid supplied from a set of pressure fluid outlet and inlet ports, so that the piston rod connected to the piston moves in a straight line The reciprocating action. ; During use, the pressure fluid is alternately supplied to the pressure fluid lead-in and lead-out port to make the piston inside the cylinder tube move forward and backward. As a result, the piston rod will make a linear reciprocating motion along the axis of the cylinder tube. ;The pressure flow system supplied to the cylinder chamber on the head cover side pushes the head cover side of the piston to extend the piston rod, and is connected from the exhaust return port to the cylinder chamber on the rod cover side through a solenoid valve not shown in the figure. The pressure fluid outlet and introduction port flows from the cylinder chamber on the rod cover side, and is again used to push the rod cover side of the piston and pull the piston rod into the cylinder tube. ;[Design Description];This design is a derivative design of patent application No. 108300695. ; The fluid pressure cylinder system of this design article has: a cylinder tube; a head cover provided at one end of the cylinder tube; a rod cover provided at the other end of the cylinder tube; extending parallel to the axis of the cylinder tube and connecting the head cover and the rod The four tie rods of the cover; the piston rod protruding from the rod cover; and the nut installed on the front end of the piston rod (refer to the reference perspective view 1 showing the names of each part and the reference perspective view 2 showing the names of each part). The cylinder pipe system is generally cylindrical in shape as a whole, and a cylinder chamber is provided inside the cylinder pipe. A piston (not shown) is accommodated in the cylinder chamber, and a piston rod is connected to the piston. ; As shown in the cross-sectional view along line A-A with the internal mechanism omitted, a bulging portion with a roughly semicircular cross-section located near the outer periphery of the cylinder tube and parallel to a tie rod extends along the length direction. A flow path is provided inside the bulging portion to allow pressure fluid to reversibly pass between the cylinder chamber on the rod cover side and the cylinder chamber on the head cover side separated by the piston. The head cover and the rod cover are roughly rectangular in shape, and on the one hand, the head cover has a thin, circular protrusion along the axis of the cylinder tube, and on the other hand, the rod cover has a protrusion along the cylinder tube. A thick cylindrical portion that bulges in the axial direction. ; One side of the rod cover is provided with: a pressure fluid lead-in and lead-out port connected to the cylinder chamber on the rod cover side; a pressure fluid lead-in and lead-out port connected to the cylinder chamber on the head cover side; an exhaust return port for use The pressure fluid in the cylinder chamber on the head cover side returns to the cylinder chamber on the rod cover side through a solenoid valve (not shown); and a throttle valve is used to adjust the flow rate of the pressure fluid that is exhausted to the outside of the cylinder tube. ;A buffer pin is provided on one side of the rod cover. The remaining three sides of the head cover and rod cover are provided with grooves of the same shape and width. ;The characteristic of this creation is the overall shape of the "fluid pressure cylinder".
