【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。;【設計說明】;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隻繋桿；以及從桿罩突出之活塞桿(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)。;缸管係呈大致八角筒狀(參照省略內部機構之A-A線剖面圖)，且在缸管之內部收納有未圖示之活塞，在該活塞連結有活塞桿。頭罩及桿罩係呈大致長方體狀，並且，在頭罩中，係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，在桿罩中，具備有沿著缸管之軸線方向膨出之厚的圓筒部。;在頭罩及桿罩之一面，設置有壓力流體導出導入通口，且在頭罩及桿罩之另一面設置有相同形狀且寬的溝部。;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. ;[Design Description];The fluid pressure cylinder 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 The four tie rods connecting the head cover and the rod cover; and the piston rod protruding from the rod cover (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 tube is roughly in the shape of an octagonal tube (refer to the cross-sectional view along line A-A with the internal mechanism omitted), and a piston (not shown) is housed inside the cylinder tube, and a piston rod is connected to the piston. The head cover and the rod cover are generally rectangular, and the head cover has a thin, circular protrusion formed along the axis of the cylinder tube. On the other hand, the rod cover has a protrusion along the axis of the cylinder tube. The thick cylindrical portion of the cylinder tube bulges in the axial direction. ; A pressure fluid outlet and introduction port is provided on one side of the head cover and the rod cover, and a groove of the same shape and width is provided on the other side of the head cover and the rod cover. ;The characteristic of this creation is the overall shape of the "fluid pressure cylinder".
