The oil seal 1132 is disposed between the Palin 1131 and the oil seal seat 1133 and is fixed to each other.
另外，本實施例之氣壓棒11更具有一活塞114、一閥座115、一內管116、一推桿117以及一作動桿118。活塞114設置於外管111內並定義出灌注氣體的一上氣室101及一下氣室102，上氣室101係靠近上密封件112，下氣室102係靠近下密封件113。閥座115係設置於外管111內並固設於上密封件112。於此，上氣室101係位於閥座115與活塞114之間。內管116係設置於外管111內，且其一端係固設於閥座115，而另一端係固設於下密封件113，例如固設於下密封件113之培林1131。推桿117係設置於外管111內並穿設上密封件112且露出於外管111。於此，推桿117可與圖1之操作桿22連接。作動桿118係穿設閥座115內並頂抵推桿117，藉由作動桿118之作動可讓閥座115開閥或關閥，以控制該氣體之流動。另外，氣壓棒11更包含一活塞桿119，其係穿設該下密封件113並固定於活塞114，並且活塞桿119之遠離活塞114之一端係設有一軸承1142。In addition, the gas pressure bar 11 of the present embodiment further has a piston 114, a valve seat 115, an inner tube 116, a push rod 117 and an actuating rod 118. The piston 114 is disposed in the outer tube 111 and defines an upper plenum 101 and a lower plenum 102 for injecting gas. The upper plenum 101 is adjacent to the upper seal 112 and the lower plenum 102 is adjacent to the lower seal 113. The valve seat 115 is disposed in the outer tube 111 and is fixed to the upper seal 112. Here, the upper air chamber 101 is located between the valve seat 115 and the piston 114. The inner tube 116 is disposed in the outer tube 111 and has one end fixed to the valve seat 115 and the other end fixed to the lower seal 113, for example, the Palin 1131 fixed to the lower seal 113. The push rod 117 is disposed in the outer tube 111 and penetrates the upper seal 112 and is exposed to the outer tube 111. Here, the push rod 117 can be coupled to the operating rod 22 of FIG. The actuating rod 118 is inserted into the valve seat 115 and abuts against the push rod 117. The actuating rod 118 is actuated to open or close the valve seat 115 to control the flow of the gas. In addition, the gas pressure bar 11 further includes a piston rod 119 which is passed through the lower sealing member 113 and fixed to the piston 114, and a bearing 1142 is disposed at one end of the piston rod 119 away from the piston 114.
轉動件12例如為一滾動軸承，並可藉由一固定件F固設於外管111及下密封件113。固定件F例如為一螺絲，螺絲之一側可例如藉由螺紋連結下密封件113，例如是油封座1133，另一側可連接轉動件12。此外，在本實施例中，固定件F固設於下密封件113之該部分，即油封座1133，可由金屬材質（例如鋁合金）製成以提升固定件F與油封座1133之連結強度。在本實施例中，油封座1133之厚度係例如從10mm增加到30mm以進一步提升連結強度。此外，於本實施例中，該固定件F進一步包括一個將該外管111與該轉動件12間隔開的隔離部I，藉以避免該轉動件12在轉動的時候與該外管111接觸摩擦。The rotating member 12 is, for example, a rolling bearing and can be fixed to the outer tube 111 and the lower sealing member 113 by a fixing member F. The fixing member F is, for example, a screw, and one side of the screw can be coupled to the lower sealing member 113, for example, by a screw, for example, the oil sealing seat 1133, and the other side can be connected to the rotating member 12. In addition, in this embodiment, the fixing member F is fixed to the portion of the lower sealing member 113, that is, the oil sealing seat 1133, and may be made of a metal material (for example, an aluminum alloy) to improve the joint strength between the fixing member F and the oil seal seat 1133. In the present embodiment, the thickness of the oil seal seat 1133 is increased, for example, from 10 mm to 30 mm to further increase the joint strength. In addition, in the embodiment, the fixing member F further includes a partitioning portion I that separates the outer tube 111 from the rotating member 12, so as to prevent the rotating member 12 from coming into frictional contact with the outer tube 111 when rotating.
復歸元件13之一側係具有一第一導斜面131及一第二導斜面132。氣壓棒11係穿設復歸元件13，且轉動件12係配置以沿第一導斜面131或第二導斜面132轉動至一常態位置P，於此，常態位置P例如是第一導斜面131與第二導斜面132之一較高的相接處，並且在一實施例中，第一導斜面131與第二導斜面132可對稱設置。需說明的是，藉由轉動件12以滾動接觸的方式與第一或第二導斜面131、132接觸，進而降低兩者之間的摩擦力以及減少磨耗，使得轉動件12能順暢地沿著第一或第二導斜面131、132滾動並延長使用壽命。One side of the reset element 13 has a first guiding slope 131 and a second guiding slope 132. The gas pressure rod 11 is threaded through the resetting element 13, and the rotating member 12 is configured to rotate along the first guiding surface 131 or the second guiding surface 132 to a normal position P. Here, the normal position P is, for example, the first guiding surface 131 and One of the second guiding slopes 132 has a higher junction, and in one embodiment, the first guiding slope 131 and the second guiding slope 132 are symmetrically disposed. It should be noted that the first or second guiding surfaces 131, 132 are brought into contact by the rotating member 12 in a rolling contact manner, thereby reducing the friction between the two and reducing the wear, so that the rotating member 12 can smoothly follow along The first or second guiding ramps 131, 132 roll and extend the service life.
請參照圖3所示，當氣壓棒11處於最高位置（外管111相對活塞桿119之最大程度的外伸）的狀態時，轉動件12係處於常態位置P，即在第一導斜面131與第二導斜面132之較高的相接處。當外管111相對活塞桿119下降，由於復歸元件13不會下降，所以轉動件12會離開復歸元件13及其第一導斜面131或第二導斜面132。另外，當使用者轉動升降椅2時，轉動件12在垂直方向上會偏離常態位置P。又當氣壓棒11因著使用者的操作而上升到某一高度時，轉動件12會再次接觸第一導斜面131或第二導斜面132，並且被第一導斜面131或第二導斜面132導引至常態位置P，這樣就使得本實施例之多個可復歸氣壓棒模組1由於常態位置P的限制而對齊於同一方位。需注意者，在本實施例中，活塞桿119係與轉動件12以及外管111為同步轉動，藉此可避免下密封件113之油封1132與活塞桿119產生摩擦，進而避免氣體外漏。Referring to FIG. 3, when the gas pressure bar 11 is in the highest position (the maximum extent of the outer tube 111 with respect to the piston rod 119), the rotating member 12 is in the normal position P, that is, at the first guiding surface 131 and The higher junction of the second guiding ramps 132. When the outer tube 111 is lowered relative to the piston rod 119, since the returning element 13 does not descend, the rotating member 12 will leave the resetting element 13 and its first guiding slope 131 or second guiding slope 132. Further, when the user rotates the chair 2, the rotating member 12 deviates from the normal position P in the vertical direction. Further, when the gas pressure bar 11 rises to a certain height due to the user's operation, the rotating member 12 will again contact the first lead inclined surface 131 or the second lead inclined surface 132, and be guided by the first lead inclined surface 131 or the second leading inclined surface 132. The guidance to the normal position P is such that the plurality of returnable gas bar modules 1 of the present embodiment are aligned in the same orientation due to the limitation of the normal position P. It should be noted that in the present embodiment, the piston rod 119 rotates synchronously with the rotating member 12 and the outer tube 111, thereby preventing the oil seal 1132 of the lower sealing member 113 from rubbing against the piston rod 119, thereby preventing gas leakage.
另外，本實施例之可復位氣壓棒模組1係更包含一支持管14。復歸元件13係設置於支持管14內並固設於支持管14，例如是藉由卡設而固定於支持管14。氣壓棒11係穿設支持管14並固定於支持管14之一端，於此，活塞桿119係穿設下密封件113並固定設於支持管14之一末端，於此係藉由一鎖固件15係將活塞桿119固設於支持管14之末端，並且鎖固件15與支持管14之間設有一墊片G以提升連結強度。In addition, the resettable gas pressure bar module 1 of the embodiment further includes a support tube 14. The reset element 13 is disposed in the support tube 14 and is fixed to the support tube 14, and is fixed to the support tube 14 by, for example, snapping. The gas pressure rod 11 is passed through the support tube 14 and fixed to one end of the support tube 14. Here, the piston rod 119 is passed through the lower seal 113 and fixed to one end of the support tube 14 by a fastener. The 15 series fixes the piston rod 119 to the end of the support tube 14, and a gasket G is provided between the locker 15 and the support tube 14 to increase the joint strength.
以下係進一步說明本實施例之可復位氣壓棒模組1之構件及操作過程。The components and operation process of the resettable gas pressure bar module 1 of the present embodiment will be further described below.

As shown in FIG. 6, the lower seal 113 has a second valve hole. 1134, the piston 114 has an inner flow passage 1141 and a seal ring 1143 capable of opening and closing the opening O on one of the inner flow passages 1141. When the resettable gas pressure bar module 1 is in a first operation (for example, the outer tube 111 is lowered relative to the piston rod 119), the gas system sequentially passes through the first valve hole 1151, the outer flow path 111 and the second from the upper gas chamber 101. The valve hole 1134 flows to the lower air chamber 102; when the resettable air pressure bar module 1 is in a second operation, the gas system flows from the lower air chamber 102 to the upper air chamber 101 via the inner flow path 1141.

In Fig. 7, the user operates the operating lever 22 shown in Fig. 1 to lower the resettable gas pressure bar module 1. At this time, as shown in FIG. 8 and FIG. 9, the first gas system flows from the upper gas chamber 101 through the first valve hole 1151 of the valve seat 115, the outer flow path 111, and the second valve hole 1134 of the lower seal 113 to The lower plenum 102, and in this first actuation, the rotating member 12 will descend away from the resetting element 13 and its first guiding ramp 131 or second guiding ramp 132.
圖10為本新型一實施例之可復歸氣壓棒模組1之另一作動示意圖。如圖10所示，當使用者藉由離開座椅或藉由操作操作桿22而使可復位氣壓棒模組1在第二作動(該外管111相對活塞桿119上升)時，該氣體會頂抵活塞114，使得該密封環1143係離開內流道1141之上開口O，以致氣體可以從下氣室102經由活塞114之內流道1141而流至上氣室101。此時，轉動件12會上升，當其接觸第一導斜面131或第二導斜面132時，其係被第一導斜面131或第二導斜面132導引至常態位置P，這樣就使得本實施例之多個可復歸氣壓棒模組1由於常態位置P的限制而對齊於同一方位。FIG. 10 is a schematic view showing another operation of the returnable gas pressure bar module 1 according to an embodiment of the present invention. As shown in FIG. 10, when the user moves the resettable gas pressure bar module 1 in the second operation (the outer tube 111 rises relative to the piston rod 119) by leaving the seat or by operating the operating lever 22, the gas will The piston 114 is urged against the opening O of the inner flow passage 1141 so that gas can flow from the lower air chamber 102 to the upper air chamber 101 via the inner flow passage 1141 of the piston 114. At this time, the rotating member 12 will rise, and when it contacts the first guiding inclined surface 131 or the second guiding inclined surface 132, it is guided to the normal position P by the first guiding inclined surface 131 or the second guiding inclined surface 132, thus making this The plurality of returnable gas pressure bar modules 1 of the embodiment are aligned in the same orientation due to the limitation of the normal position P.
綜上所述，依據本新型之一種可復歸氣壓棒模組，其設置一轉動件，且轉動件藉由一固定件而固設於氣壓棒之外管及下密封件，又設置一復歸元件，且其一側係具有一第一導斜面及一第二導斜面。藉此，在使用者操作而使可復歸氣壓棒模組下降（或內縮）並轉動的情況下，當可復歸氣壓棒模組上升（或外伸）時，轉動件可再次接觸到復歸元件並可沿第一導斜面或第二導斜面轉動至一常態位置。如此，所有使用本新型之可復歸氣壓棒模組之升降裝置皆可處在常態位置而面對同一方位，進而提升使用效能。In summary, according to the present invention, a reversible gas pressure bar module is provided with a rotating member, and the rotating member is fixed to the outer tube and the lower sealing member of the gas pressure rod by a fixing member, and a resetting member is further disposed. And one side has a first guiding slope and a second guiding slope. Thereby, when the user can operate to lower (or retract) the reversible gas pressure bar module and rotate, when the returnable gas pressure bar module rises (or protrudes), the rotating member can contact the reset component again. It can be rotated to a normal position along the first guiding slope or the second guiding slope. In this way, all the lifting devices using the reversible gas bar module of the present invention can be in the normal position and face the same orientation, thereby improving the use efficiency.
