【物品用途】;本物品係一種間隔件，係介裝於例如過濾器、調節器、潤滑器等具有供給/排出壓力流體之通口的一組流體壓力機器之間，用以使前述流體壓力機器彼此連結。;在使用時，係預先將第2螺帽的圓筒部插入固定件蓋的小孔，並將第2固定件嵌合於固定件蓋的開口。由於第2固定件與固定件蓋係以可滑動的方式夾持第2螺帽之未圖示的凸緣部，因此，係在第2螺帽可轉動的狀態下，將第2螺帽、第2固定件及固定件蓋予以一體化。此外，將第1螺帽與第1螺栓鎖緊，而將第1固定件與間隔件本體予以一體化。;接著，將間隔件本體配置於未圖示的2個流體壓力機器之間，並以使前述2個流體壓力機器的通口經由間隔件本體之孔部而彼此連通的方式，將前述2個流體壓力機器之一方的凸緣分別卡合於第1固定件。在此狀態下，將與固定件蓋一體化後的第2固定件抵接於前述2個流體壓力機器之另一方的凸緣。此時，當將從間隔件本體朝向固定件蓋突出之未圖示的第2螺栓插通於第2固定件之未圖示的螺栓插通孔時，該第2螺栓的軸線與第2螺帽的軸線會大致一致。若將第2螺帽朝間隔件本體側螺入，而將第2螺帽與未圖示之第2螺栓予以鎖緊，則前述另一方的凸緣會與第2固定件卡合，而將前述2個流體壓力機器彼此連結。;【設計說明】;本設計之間隔件係具有：間隔件本體，係具有供壓力流體流通之孔部；第1固定件，係設於間隔件本體之一端側；第1螺帽及第1螺栓，係用以將第1固定件固定於間隔件本體；第2固定件，係設於間隔件本體之另一端側；第2螺帽，係以可轉動的方式安裝於第2固定件；固定件蓋，係外嵌於第2固定件與第2螺帽。(參照參考圖1及參考圖2);固定件蓋係朝向間隔件本體形成有開口之容器體，且在相當於底部之部分的中央，係設有供第2螺帽插通的小孔。第2螺帽係具有：在周側面刻有滾紋之圓筒部、及被保持於固定件蓋之內側之未圖示的凸緣部，而該凸緣部的半徑係形成為大於固定件蓋之前述小孔的半徑。[Use of article]; This article is a spacer that is installed between a group of fluid pressure machines such as filters, regulators, lubricators, etc., which have ports for supplying/discharging pressure fluid, to make the aforementioned fluid pressure Machines are connected to each other. ; When using, insert the cylindrical part of the second nut into the small hole of the fastener cover in advance, and fit the second fastener into the opening of the fastener cover. Since the second fixing piece and the fixing piece cover slidably hold the flange portion (not shown) of the second nut, the second nut, The second fixing piece and the fixing piece cover are integrated. In addition, the first nut and the first bolt are locked, and the first fixing part and the spacer body are integrated. ; Next, the spacer body is arranged between two fluid pressure machines (not shown), and the two fluid pressure machines are connected in such a manner that the openings of the two fluid pressure machines are communicated with each other through the holes of the spacer body. The flange on one side of the fluid pressure machine is respectively engaged with the first fixing member. In this state, the second fixture integrated with the fixture cover is brought into contact with the other flange of the two fluid pressure devices. At this time, when the second bolt (not shown) protruding from the spacer body toward the fastener cover is inserted into the bolt insertion hole (not shown) of the second fastener, the axis of the second bolt is aligned with the second bolt. The axes of the caps will be roughly aligned. If the second nut is screwed in toward the spacer body side and the second nut is locked with the second bolt (not shown in the figure), the other flange will engage with the second fixing piece, and the second nut will be tightened with the second bolt (not shown). The two aforementioned fluid pressure machines are connected to each other. ;[Design Description];The spacer in this design has: a spacer body, which has a hole for pressure fluid to flow; a first fixing piece, which is located on one end side of the spacer body; a first nut and a first The bolt is used to fix the first fixing part to the spacer body; the second fixing part is provided at the other end side of the spacer body; the second nut is rotatably installed on the second fixing part; The fixing piece cover is externally embedded in the second fixing piece and the second nut. (Refer to Figures 1 and 2); The fastener cover is a container body with an opening formed toward the spacer body, and is provided with a small hole for the second nut to pass through in the center of the portion equivalent to the bottom. The second nut has a cylindrical portion with knurls on its peripheral surface, and a flange portion (not shown) held inside the fastener cover, and the radius of the flange portion is formed to be larger than that of the fastener. Cover the radius of the aforementioned hole.
