At least one washer 23 and at least one elastic washer 60, wherein the first body 10 and the second body 20 can be rotated relative to each other by the central axis 30, and the position of the adjustment ring 50 on the central axis 30 can be adjusted The frictional force between the components is changed, and then the torque value of the rotating shaft structure 1 during rotation is adjusted. The assembly of these components is described in detail below: please refer to Figures 1 and 2. Figures 1 and 2 describe the structure of the rotating shaft structure 1. The first body 10 includes a first connecting portion 11, and the second body 20 includes a second The connecting portion 21, since the central shaft 30 rotatably penetrates the first connecting portion 11 and the second connecting portion 21, the first body 10 can be rotated relative to the second body 20 by the first connecting portion 11 and the central shaft 30 to a certain extent Similarly, the second body 20 can be rotated by a certain angle relative to the first body 10 through the second connecting portion 21 and the central shaft 30. In addition, two spacers 23 are respectively sleeved on the central shaft 31, and each The gasket 23 abuts against the first connecting portion 11 and the second connecting portion 21. Specifically, the first connecting portion 11 has a first shaft hole, the second connecting portion 21 has a second shaft hole, and the central axis 30 passes through the first connecting portion 11 and the second connecting portion 21 by the first shaft hole and the second shaft hole. As shown in Figures 1 and 2, in this embodiment, the rotating shaft structure 1 can be, but is not limited to, a pair of binoculars, the first body 10 can be the left half of the binoculars, and the second body 20 can be Is the right half of the binoculars, the first connecting portion 11 can be a concave portion, and the second connecting portion 21 can be a convex portion. It is worth noting that the first connecting portion 11 and the second connecting portion 21 is not necessarily a concave portion and a convex portion, as long as it is a shape that enables the first connecting portion 11 and the second connecting portion 21 to match each other.

如第2圖所示，中心軸30包括一限位部31，限位部31連接於中心軸30的其中一端，當中心軸30穿過第一銜接部11、該等墊片23以及第二銜接部21後，限位部31抵接於第一銜接部11的一端面，另外，第一墊片36以及第二墊片34依序設置於固定座40上一環形凹槽，中心軸30的另一端則依序穿過第二墊片34、第一墊片36、固定座40以及二彈性墊片60，再透過將調整環50套設並固定於中心軸30上，以將第一墊片36、第二墊片34、固定座40以及二彈性墊片60固定於中心軸30上，並推抵第二墊片34抵接於第二本體20。 As shown in Figure 2, the central shaft 30 includes a limiting portion 31, which is connected to one end of the central shaft 30. When the central shaft 30 passes through the first connecting portion 11, the spacers 23 and the second After the connecting portion 21, the limiting portion 31 abuts on one end surface of the first connecting portion 11. In addition, the first gasket 36 and the second gasket 34 are sequentially arranged in an annular groove on the fixing seat 40, and the central axis 30 The other end passes through the second washer 34, the first washer 36, the fixing seat 40 and the second elastic washer 60 in sequence, and then the adjusting ring 50 is sleeved and fixed on the central shaft 30 to fix the first The gasket 36, the second gasket 34, the fixing seat 40 and the two elastic gaskets 60 are fixed on the central shaft 30, and push the second gasket 34 against the second body 20.

請參閱第3圖，第3圖描述組裝完成後的旋轉軸結構1的結構，第一本體10更包括一溝槽13，溝槽13形成於第一本體10上相對應於第二墊片34之位置，因此當調整環50將第一墊片36、第二墊片34、固定座40以及二彈性墊片60固定於第一本體10與第二本體20上時，第二墊片34僅抵接於第二本體20，並不會抵接於第一本體10，反而是藉由溝槽13與第一本體10之間形成一間隙，當調整環50緊密固定後，如此設置將使第二墊片34與第二本體20彼此不可相對轉動，而由於第二墊片34與第一本體10之間存在著該間隙，又使第一本體10可以繞著中心軸30相對於第二本體20進行轉動。其中，第二墊片34為一非彈性墊片，於本實施例中可為一金屬墊片，第一墊片36為一彈性墊片，於本實施例中可為一尼龍 墊片。 Please refer to FIG. 3, which describes the structure of the rotating shaft structure 1 after the assembly is completed. The first body 10 further includes a groove 13 formed on the first body 10 corresponding to the second gasket 34 Therefore, when the adjusting ring 50 fixes the first gasket 36, the second gasket 34, the fixing seat 40 and the second elastic gasket 60 on the first body 10 and the second body 20, the second gasket 34 is only It abuts against the second body 20, and does not abut against the first body 10. Instead, a gap is formed between the groove 13 and the first body 10. When the adjusting ring 50 is tightly fixed, this arrangement will make the The two spacers 34 and the second body 20 cannot rotate relative to each other, and the gap between the second spacer 34 and the first body 10 allows the first body 10 to be relative to the second body around the central axis 30 20 to rotate. The second gasket 34 is a non-elastic gasket, which can be a metal gasket in this embodiment, and the first gasket 36 is an elastic gasket, which can be a nylon gasket in this embodiment.

欲調整旋轉軸結構1於轉動時的扭力值時，可通過控制調整環50的預緊力來改變位於中心軸30上的複數個元件在端面與端面之間的作用力，以增加或減少轉動時該等元件之間的摩擦力，從而設定旋轉軸結構1於轉動時的扭力值，具體而言，欲增加扭力值時，先調整調整環50於中心軸30之軸向位置，再鎖緊調整環50使之壓縮二彈性墊片60，以藉由彈性墊片60的彈力產生一軸向的壓力，該壓力會壓緊第一墊片36以及第二墊片34，並增加第一墊片36、第二墊片34與第二本體20之間的摩擦力，使得第二墊片34與第二本體20彼此不可相對轉動，同時，由於第一本體10、該等墊片23與第二本體20之間產生干涉，且固定座40、第一墊片36與第二墊片34之間產生干涉，因而增加第一本體10與第二本體20於轉動時的扭力值。其中，彈性墊片60可為盤形墊片(disc washer)、碟形墊片(belleville washer)或錐形墊片(conical washer)。 To adjust the torque value of the rotating shaft structure 1 during rotation, the pre-tightening force of the adjusting ring 50 can be controlled to change the force between the end surface and the end surface of the plurality of elements on the central shaft 30 to increase or decrease the rotation The frictional force between these elements is used to set the torque value of the rotating shaft structure 1 during rotation. Specifically, to increase the torque value, first adjust the axial position of the adjustment ring 50 on the central shaft 30, and then lock it The adjusting ring 50 compresses the two elastic gaskets 60 to generate an axial pressure by the elastic force of the elastic gasket 60. The pressure will compress the first gasket 36 and the second gasket 34 and increase the first gasket The friction between the sheet 36, the second gasket 34 and the second body 20 makes the second gasket 34 and the second body 20 non-rotatable relative to each other. At the same time, due to the first body 10, the gaskets 23 and the second body 20 Interference occurs between the two bodies 20, and interference occurs between the fixing seat 40, the first spacer 36 and the second spacer 34, thereby increasing the torque value of the first body 10 and the second body 20 when rotating. Wherein, the elastic washer 60 can be a disc washer, a belleville washer, or a conical washer.

另外，調整環50的內側可具有一內螺紋(未繪示)，而中心軸30相對於限位部31的另一端可具有一外螺紋(未繪示)，使得調整環50可鎖固於中心軸30上某一位置，或者，調整環50本身也可不具有該內螺紋，而是再另外藉由一具有內螺紋的固定件以將調整環50鎖固於中心軸30上某一位置，可以了解的是，只要是能將調整環50固定於中心軸30上某一位置的組裝方式都是可行的。 In addition, the inner side of the adjusting ring 50 may have an internal thread (not shown), and the other end of the central shaft 30 relative to the limiting portion 31 may have an external thread (not shown), so that the adjusting ring 50 can be locked to A certain position on the central shaft 30, or the adjustment ring 50 itself may not have the internal thread, but a fixing member with internal threads is used to lock the adjustment ring 50 at a certain position on the central shaft 30. It can be understood that any assembly method that can fix the adjustment ring 50 to a certain position on the central shaft 30 is feasible.

於另一實施例中，第一銜接部11與第二銜接部21之間也可不用設置該等墊片23，且也可不用設置第二墊片34於固定座40上。當調整環50被緊密地鎖固於中心軸30時，第一本體10以及第二本體20之間 的干涉產生，且同時第一墊片36以及固定座40之間的干涉也產生，以增加第一本體10與第二本體20於轉動時的扭力值。 In another embodiment, the spacers 23 may not be arranged between the first connecting portion 11 and the second connecting portion 21, and the second spacers 34 may not be arranged on the fixing seat 40. When the adjusting ring 50 is tightly locked to the central shaft 30, interference between the first body 10 and the second body 20 is generated, and at the same time the interference between the first gasket 36 and the fixing seat 40 is also generated to increase The torque values of the first body 10 and the second body 20 during rotation.

本發明旋轉軸結構1在轉動過程中除了第一本體10以及第二本體20相對應端面的相互作用力以外，更透過給予調整環50的預緊力壓緊或釋放位於中心軸30的該等元件，以進行旋轉軸結構1於轉動時的扭力值設定，旋轉軸結構1除了應用於雙筒望遠鏡以外，還可應用於其他具有繞著中心軸轉動之結構的操作裝置，以增加該裝置在操作上的變化性。 In addition to the interaction force of the corresponding end surfaces of the first body 10 and the second body 20 during the rotation of the rotating shaft structure 1 of the present invention, the pre-tightening force given to the adjusting ring 50 compresses or releases those on the central axis 30. Element to set the torque value of the rotating shaft structure 1 during rotation. The rotating shaft structure 1 can be applied to other operating devices that have a structure that rotates around the central axis in addition to being applied to binoculars to increase the device’s Operational variability.
