In the following embodiments, the same reference numerals will be given to the same or similar elements or structural features thereof.
請參閱第1圖,本創作第1實施例之升降座管10包含有一根外管20、一根內管30,以及一個限位襯套40。Referring to Fig. 1, the lifting seat tube 10 of the first embodiment of the present invention comprises an outer tube 20, an inner tube 30, and a limiting bushing 40.
內管30穿設於外管20且藉由一組氣壓缸50(如第4圖所示)的控制而相對外管20上下位移,至於如何利用氣壓缸50控制內管30升降為習知技術,為了節省篇幅,在此容不贅述。內管30之頂端位於外管20外,主要用來供一個座墊(圖中未示)安裝,內管30之底端位於外管20內且具有三個凸部32(實際只要至少一個即可),凸部32設於內管30之外周面且相對於內管30之軸心呈等間隔排列,此外,凸部32在本實施例中呈長條狀,且凸部32之延伸方向平行於內管30之軸向。The inner tube 30 is disposed through the outer tube 20 and is vertically displaced relative to the outer tube 20 by a set of pneumatic cylinders 50 (shown in FIG. 4). How to control the inner tube 30 to rise and lower by using the pneumatic cylinder 50 is a conventional technique. In order to save space, I will not repeat them here. The top end of the inner tube 30 is located outside the outer tube 20 and is mainly used for mounting a seat cushion (not shown). The bottom end of the inner tube 30 is located in the outer tube 20 and has three convex portions 32 (actually only at least one is The convex portions 32 are provided on the outer circumferential surface of the inner tube 30 and are arranged at equal intervals with respect to the axial center of the inner tube 30. Further, the convex portion 32 is elongated in the present embodiment, and the extending direction of the convex portion 32 Parallel to the axial direction of the inner tube 30.
限位襯套40被內管30所穿設且具有一個套筒41、一個套環44及一個束環46,如第2及3圖所示:The limit bushing 40 is bored by the inner tube 30 and has a sleeve 41, a collar 44 and a bundle ring 46, as shown in Figures 2 and 3:
套筒41位於外管20內且具有三個限位部,各個限位部之頂、底兩端沿著內管30之軸向具有一高度差,在本實施例中,每一個限位部由七個沿著內管30之軸向呈階梯狀排列之限位槽42所構成,且每一個限位部以一對一的方式設於內管30之凸部32的上方。此外,套筒41之頂端的外周面具有三個卡合部43,卡合部43相對於套筒41之中心呈等間隔排列。The sleeve 41 is located in the outer tube 20 and has three limiting portions. The top and bottom ends of each limiting portion have a height difference along the axial direction of the inner tube 30. In this embodiment, each of the limiting portions The plurality of limiting portions 42 are arranged in a stepped manner along the axial direction of the inner tube 30, and each of the limiting portions is disposed above the convex portion 32 of the inner tube 30 in a one-to-one manner. Further, the outer peripheral surface of the tip end of the sleeve 41 has three engaging portions 43, and the engaging portions 43 are arranged at equal intervals with respect to the center of the sleeve 41.
套環44抵靠於外管20之頂端,且套環44之底端的內周面具有三個卡合槽45,套環44之卡合槽45以一對一的方式嵌接於套筒41之卡合部43,使兩者能同步作動。The collar 44 abuts against the top end of the outer tube 20, and the inner peripheral surface of the bottom end of the collar 44 has three engaging grooves 45, and the engaging grooves 45 of the collar 44 are engaged with the sleeve 41 in a one-to-one manner. The engaging portion 43 enables the two to operate in synchronization.
束環46將外管20之頂端與套環44之底端套接在一起,當束環46在鬆開之後即可轉動套環44,由套環44再帶動套筒41一起旋轉。The collar 46 sleeves the top end of the outer tube 20 with the bottom end of the collar 44. When the collar 46 is released, the collar 44 can be rotated, and the sleeve 44 re-drives the sleeve 41 to rotate together.
從上述可知,當騎乘者想要調整座墊的高度時,先開啟氣壓缸50驅動內管30上升至一期望高度之後,再關閉氣壓缸50來定位內管30,接著鬆開束環46,再藉由轉動套環44來帶動套筒41一起旋轉,使套筒41之其中一個限位槽42嵌卡於內管30之凸部32,例如在第4圖中,套筒41用最上面的一個限位槽42嵌卡內管30之凸部32,至於在第5圖中,套筒41則是用最下面的一個限位槽42嵌卡內管30之凸部32,最後確認內管30的高度沒有問題之後再將束環46重新束緊之後即完成調整。As can be seen from the above, when the rider wants to adjust the height of the seat cushion, first open the air cylinder 50 to drive the inner tube 30 to a desired height, then close the air cylinder 50 to position the inner tube 30, and then release the collar 46. Then, by rotating the collar 44 to rotate the sleeve 41 together, one of the limiting slots 42 of the sleeve 41 is embedded in the convex portion 32 of the inner tube 30. For example, in FIG. 4, the sleeve 41 is used most. The upper limit groove 42 is embedded in the convex portion 32 of the inner tube 30. As shown in FIG. 5, the sleeve 41 is embedded with the convex portion 32 of the inner tube 30 by the lowermost limit groove 42, and finally confirmed. The adjustment is completed after the height of the inner tube 30 is no problem and the bundle ring 46 is re-tensioned.
在騎乘結束之後,騎乘者可以利用氣壓缸50將內管30的高度降到最低以利收納(如第3圖所示),這時候因為限位襯套40已經配合騎乘者的需求而調整到定位,所以在下一次使用時利用內管30之凸部32與限位襯套40之限位槽42之間的配合,內管30的上升高度會受到限制,對同一個騎乘者來說不需要再重新調整座墊高度,如此即可有效節省操作時間及增加使用便利性。After the end of the ride, the rider can use the pneumatic cylinder 50 to minimize the height of the inner tube 30 for storage (as shown in Fig. 3), because the limit bushing 40 has already met the needs of the rider. While being adjusted to the positioning, the fitting between the convex portion 32 of the inner tube 30 and the limiting groove 42 of the limiting bush 40 is utilized in the next use, and the rising height of the inner tube 30 is restricted to the same rider. There is no need to re-adjust the height of the seat cushion, which saves operating time and increases ease of use.
另一方面,限位部及凸部的結構可以有不同變化,在本創作第2實施例中,限位部為一個沿著內管30之軸向延伸之斜面52(如第6圖所示),斜面可以呈筆直延伸或弧狀延伸,並不加以限定,至於凸部54可以圓柱體(如第6圖所示)、球體(圖中未示)或方鍵(圖中未示),藉由兩者之間的配合,同樣可以限制內管30的上升高度來達到調整行程的效果。On the other hand, the structure of the limiting portion and the convex portion may be differently changed. In the second embodiment of the present invention, the limiting portion is a slope 52 extending along the axial direction of the inner tube 30 (as shown in FIG. 6). The inclined surface may extend straight or arcuately and is not limited. The convex portion 54 may be a cylinder (as shown in FIG. 6), a sphere (not shown) or a square key (not shown). By the cooperation between the two, the rising height of the inner tube 30 can also be restricted to achieve the effect of adjusting the stroke.
