請參閱第一及二圖,為本創作一較佳實施例所提供之方向控制機構10,主要是用來控制內視鏡之一鏡頭(圖中未示)的拍攝方向。本創作之方向控制機構10包含有一轉軸20、一方向轉盤30,以及一制動組件40。Please refer to the first and second figures. The direction control mechanism 10 provided for the preferred embodiment of the present invention is mainly used for controlling the shooting direction of a lens (not shown) of the endoscope. The directional control mechanism 10 of the present invention includes a rotating shaft 20, a directional turntable 30, and a brake assembly 40.
轉軸20具有一軸桿22及一轉輪24,軸桿22之一端藉由螺設一固定環26而與方向轉盤30進行固定,轉輪24連接於軸桿22之另一端,用以供內視鏡之一轉向控制線(圖中未示)繞設。藉此,轉軸20便能夠受到方向轉盤30之帶動而透過轉輪24來拉動轉向控制線,使轉向控制線再帶動鏡頭進行轉向。The rotating shaft 20 has a shaft 22 and a rotating wheel 24. One end of the shaft 22 is fixed to the direction dial 30 by screwing a fixing ring 26, and the rotating wheel 24 is connected to the other end of the shaft 22 for internal view. One of the mirrors is turned around the control line (not shown). Thereby, the rotating shaft 20 can be driven by the direction dial 30 to pass through the turning wheel 24 to pull the steering control line, so that the steering control line drives the lens to perform steering.
請參照第二及三圖,制動組件40具有一軸套41、一制動座42、三鋼珠43,以及一控制座44。軸套41套設於轉軸20而不會與轉軸20一起轉動且具有一軸部412,軸部412的斷面形狀為矩形;制動座42具有一座體45及一制動片46,座體45之一側面具有多數個鋼珠固定孔452,該些鋼珠固定孔452是以轉軸20之軸桿22為中心而呈環狀排列,制動片46固定於座體45之另一側面且相對於方向轉盤30,此外,制動座42具有一矩形套孔454,矩形套孔454貫穿座體45及制動片46,用以套接固定於軸套41之軸部412,使得制動座42無法相對軸套41轉動而能沿著轉軸20之軸向相對軸套41移動;該些鋼珠43設置於制動座42之其中三個鋼珠固定孔452內,並且局部露出於鋼珠固定孔452外;控制座44具有一轉盤47及一操控桿48,轉盤47具有一圓形套孔472,用以可轉動地套設於軸套41之軸部412,而且,轉盤47具有三定位槽49,用以分別供一個鋼珠43容設,各定位槽49是以轉軸20之軸桿22為中心而呈弧狀延伸,而且,各定位槽49之槽面492在本實施例中是呈現階梯狀延伸,使得各定位槽49之一第一端 494至制動座42之距離大於各定位槽49之一第二端496至制動座42之距離,此外,轉盤47之外周緣連接操控桿48之一端,使得轉盤47能夠受到操控桿48之帶動而轉動。Referring to FIGS. 2 and 3, the brake assembly 40 has a sleeve 41, a brake seat 42, three steel balls 43, and a control seat 44. The sleeve 41 is sleeved on the rotating shaft 20 and does not rotate together with the rotating shaft 20 and has a shaft portion 412. The shaft portion 412 has a rectangular cross section; the braking base 42 has a body 45 and a brake pad 46, and one of the seat bodies 45 A plurality of steel ball fixing holes 452 are formed on the side surface, and the steel ball fixing holes 452 are annularly arranged around the shaft 22 of the rotating shaft 20, and the brake piece 46 is fixed to the other side of the seat body 45 with respect to the direction turntable 30, In addition, the brake base 42 has a rectangular sleeve hole 454. The rectangular sleeve hole 454 extends through the base body 45 and the brake pad 46 for socketing and fixing to the shaft portion 412 of the sleeve 41, so that the brake seat 42 cannot rotate relative to the sleeve 41. The steel ball 43 is disposed in the three steel ball fixing holes 452 of the brake base 42 and partially exposed outside the steel ball fixing hole 452; the control seat 44 has a turntable 47. And a control lever 48, the turntable 47 has a circular sleeve hole 472 for rotatably sleeved on the shaft portion 412 of the sleeve 41, and the turntable 47 has three positioning slots 49 for respectively for a steel ball 43 It is assumed that each positioning groove 49 extends in an arc shape centering on the shaft 22 of the rotating shaft 20. Further, each positioning groove 49 faces the groove 492 in this embodiment is a stepped extension presented embodiment, each of the positioning grooves such that a first end of one of the 49 The distance from the 494 to the brake base 42 is greater than the distance from the second end 496 of each of the positioning slots 49 to the brake base 42. In addition, the outer circumference of the turntable 47 is connected to one end of the control rod 48, so that the turntable 47 can be driven by the control rod 48. Turn.
當操作人員要調整內視鏡之鏡頭方向時,首先施力扳動操控桿48而將控制座44轉動至一釋放位置P1,使各鋼珠43位於各定位槽49之第一端494,如第四及五圖所示,此時的控制座44不會將制動座42朝方向轉盤30的方向推頂,因此方向轉盤30可以任意轉動,並在轉動的過程中拉動轉向控制線來達到調整鏡頭方向的目的。When the operator wants to adjust the lens direction of the endoscope, firstly force the lever 48 to rotate the control seat 44 to a release position P1, so that the steel balls 43 are located at the first end 494 of each positioning slot 49, as described As shown in FIGS. 4 and 5, the control seat 44 at this time does not push the brake base 42 toward the direction dial 30, so the direction dial 30 can be arbitrarily rotated, and the steering control line is pulled during the rotation to achieve the adjustment lens. The purpose of the direction.
當操作人員藉由轉動方向轉盤30將鏡頭調整到所需要的位置時,接著透過操控桿48將控制座44轉動至一制動位置P2,使各鋼珠43沿著各定位槽49之階梯狀槽面492爬升至各定位槽49之第二端496,如第六及七圖所示,由於各定位槽49之第二端496至制動座42之距離小於各定位槽49之第一端494至制動座42之距離,所以控制座44會藉由各定位槽49之槽面492推頂各鋼珠43而將制動座42朝方向轉盤30的方向推頂,使制動座42沿著轉軸20之軸向朝方向轉盤30移動,並藉由制動片46緊抵方向轉盤30,如此即可讓方向轉盤30無法任意轉動來完成鏡頭的定位。When the operator adjusts the lens to the desired position by turning the direction dial 30, the control seat 44 is then rotated to a braking position P2 through the operating lever 48, so that the steel balls 43 follow the stepped groove surface of each positioning groove 49. 492 climbs to the second end 496 of each positioning slot 49. As shown in the sixth and seventh figures, since the distance from the second end 496 of each positioning slot 49 to the brake seat 42 is less than the first end 494 of each positioning slot 49 to the brake The distance of the seat 42 is such that the control seat 44 pushes the steel balls 43 by the groove faces 492 of the positioning grooves 49 to push the brake seat 42 toward the direction turntable 30, so that the brake seat 42 is along the axial direction of the rotating shaft 20. Moving toward the direction dial 30 and pressing the brake pad 46 against the direction dial 30, the direction dial 30 can not be arbitrarily rotated to complete the positioning of the lens.
綜上所述,本創作之方向控制機構10利用定位槽49之高度落差設計,讓制動座42能夠透過鋼珠43而受到控制座44之控制來快速釋放或確實迫緊方向轉盤30,以達到方向調整及定位的效果,與習用技術相比之下,本創作 之方向控制機構10的結構更為簡單,操作起來也相當容易,同時具有良好的制動效果。In summary, the directional control mechanism 10 of the present invention utilizes the height drop design of the positioning slot 49 to allow the brake seat 42 to be controlled by the control seat 44 through the steel ball 43 to quickly release or indeed urge the direction dial 30 to achieve the direction. The effect of adjustment and positioning, compared with the conventional technology, this creation The structure of the direction control mechanism 10 is simpler, and the operation is also relatively easy, and has a good braking effect.
然而在此需要補充說明的是,制動座42之鋼珠固定孔452、鋼珠43,以及控制座44之定位槽49的數目可以依據實際需要而有所變化,只要至少兩個即可達到應有的效果,再者,定位槽49之槽面492不一定要呈階梯狀延伸,亦可呈傾斜狀延伸,只要定位槽49之兩端具有高度落差即可。除此之外,請參照第八圖所示,本創作可以配合兩條不同的轉向控制線而將兩組方向控制機構10結合在一起,由於兩組方向控制機構10的結構差異主要在於第一組方向控制機構10之控制座44是藉由操控桿48來驅動轉盤47,第二組方向控制機構10之控制座44則是藉由一操控鈕50來驅動轉盤47,其他方面則是完全相同,為了節省篇幅,在此容不再贅述第二組方向控制機構10之細部構造及操作過程。However, it should be additionally noted that the number of the ball fixing holes 452, the steel balls 43, and the positioning grooves 49 of the control seat 44 of the brake base 42 may be changed according to actual needs, as long as at least two can achieve the proper. The effect is that the groove surface 492 of the positioning groove 49 does not have to extend in a stepwise manner, and may extend in a slope shape as long as the two ends of the positioning groove 49 have a height drop. In addition, please refer to the eighth figure, the author can combine the two sets of direction control mechanisms 10 with two different steering control lines, because the structural difference between the two sets of direction control mechanisms 10 is mainly in the first The control seat 44 of the group direction control mechanism 10 drives the turntable 47 by the control lever 48, and the control seat 44 of the second group of the direction control mechanism 10 drives the turntable 47 by a control button 50, otherwise the same is the same. In order to save space, the detailed construction and operation process of the second group of direction control mechanisms 10 will not be described herein.
最後,本創作於前揭實施例中所揭露的構成元件,僅為舉例說明,並非用來限制本案之範圍,其他等效元件的替代或變化,亦應為本案之申請專利範圍所涵蓋。In the meantime, the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention.
