具体实施方式
为了便于本领域技术人员理解，下面将结合具体实施例及附图对本发明作进一步详细描述。
请参考图1-3，本发明实施例1包括：
一种分体式底座的光轴结构，包括设置有光通道11的底座12、与底座12连接并形成腔室的上盖13、与光通道11配合动作以切换开关状态的按钮14、以及驱使按钮14回位的弹簧15，光通道11中段或末端的两侧设置有对置的两 个光对管，底座12与光通道11分体式连接。在本实施例中，光对管对置安装，在其他实施例中，也可以利用光折射来安装光对管。光通道11位于光通道块18，光通道块18与底座12分体式连接。底座12设置有贯通开窗16，光通道块18安装在贯通开窗16。光通道11具有遮光特性。
两个光对管分别为光发射器和光接收器，按钮14具有一能够阻挡光线的挡光柱17，按钮14通过上下移动来实现挡光柱17阻挡光对管和不遮挡光对管的两种状态，挡光柱17阻挡光对管和不遮挡光对管的两种状态分别对应光轴结构的开启和关闭状态。
光通道块18与底座12为两个独立的部件，故光通道块与底座可采用不同的材质制作，由于光通道与按钮需要长期接触并摩擦，光通道对耐磨特性和特光特性的需求较大，因此光通道块可针对性地采用具有耐磨特性、遮光性好的材质制作，而底座对耐磨和遮光特性的要求并不高，可采用其他材质制作。此外，由于底座作为外表，对美观性有要求，由于底座与光通道块相互分离独立，可对底座和光通道块进行不同颜色的着色设计，甚至还可根据需要做成透明的，极大地丰富了轴体外观设计的可选择空间。
如附图2爆炸图和附图3装配图所示，光通道块18卡接在贯通开窗16，光通道块18的四角可全部或部分设置扣位，光通道块18与底座12卡扣连接；在其他实施例中，光通道块18可与底座12榫卯连接，光通道块18设置榫头、底座12设置榫槽，或光通道块18设置榫槽、底座12设置榫头；在其他实施例中，光通道块18可与底座12过盈连接，光通道块18与底座12相互卡紧；在其他实施例中，光通道块18可与底座12通过胶水连接。
外力按钮14时，按钮14顺着光通道块18的光通道11的走向上下移动，按钮14向下移动一段距离后，挡光柱17阻挡光发射器发出的光线，使得光接 收器无法接到来自光发射器发出的光线，从而使得光轴实现开关功能。外力撤走后，按钮14在弹簧15的作用下回位，挡光柱17不再阻挡光发射器发出的光线，使得光接收器可以接到来自光发射器发出的光线，从而使得光轴实现开关功能。
本实施例的光轴为分体式结构，可任意组合材质多样性搭配和颜色多样性搭配。
请参考图4-6，本发明实施例2包括：
一种分体式底座的光轴结构，包括设置有光通道21的底座22、与底座22连接并形成腔室的上盖23、与光通道21配合动作以切换开关状态的按钮24、以及驱使按钮24回位的弹簧25，光通道21中段或末端的两侧设置有对置的两个光对管，底座22与光通道21分体式连接。光通道21位于光通道块28，光通道块28与底座22分体式连接。底座22设置有贯通开窗26，光通道块28安装在贯通开窗26。光通道21具有遮光特性。
两个光对管分别为光发射器和光接收器，按钮24具有一能够阻挡光线的挡光柱27，按钮24通过上下移动来实现挡光柱27阻挡光对管和不遮挡光对管的两种状态，挡光柱27阻挡光对管和不遮挡光对管的两种状态分别对应光轴结构的开启和关闭状态。
光通道块28与底座22为两个独立的部件，故光通道块与底座可采用不同的材质制作，由于光通道与按钮需要长期接触并摩擦，光通道对耐磨特性和遮光特性的需求较大，因此光通道块可针对性地采用具有耐磨特性和遮光特性的材质制作，而底座对耐磨和遮光特性的要求并不高，可采用其他材质制作。此外，由于底座作为外表，对美观性有要求，由于底座与光通道块相互分离独立，可对底座和光通道块进行不同颜色的着色设计，甚至还可根据需要做成透明的， 极大地丰富了轴体外观设计的可选择空间。
如附图5爆炸图和附图6装配图所示，光通道块28铆接在贯通开窗26，光通道块28的四角可全部或部分设置铆接块，贯通开窗26设置有与前述铆接块配合的支撑块，光通道块28与底座22相互铆接，铆钉29将铆接块与支撑块稳固连接。
外力按钮24时，按钮24顺着光通道块28的光通道21的走向上下移动，按钮24向下移动一段距离后，挡光柱27阻挡光发射器发出的光线，使得光接收器无法接到来自光发射器发出的光线，从而使得光轴实现开关功能。外力撤走后，按钮24在弹簧25的作用下回位，挡光柱27不再阻挡光发射器发出的光线，使得光接收器可以接到来自光发射器发出的光线，从而使得光轴实现开关功能。
本实施例的光轴为分体式结构，可任意组合材质多样性搭配和颜色多样性搭配。
请参考图7-12，本发明实施例3包括：
一种分体式底座的机械轴结构，包括具有中心槽31的底座32、与底座32连接并形成腔室的上盖33、端子34、切换片35、驱使切换片35与端子34接通或断开的按钮36、以及驱使按钮36回位的弹簧37，按钮36可相对于中心槽31上下滑动，底座32与中心槽31分体式连接。中心槽31位于中心块38，中心块38与底座32分体式连接。底座32设置有贯通开窗39，中心槽31安装在贯通开窗39。端子34连接在底座32。切换片35连接在底座32。
由于底座作为外表，对美观性有要求，由于底座与中心块相互分离独立，可对底座和中心块进行不同颜色的着色设计，甚至还可根据需要做成透明的，极大地丰富了轴体外观设计的可选择空间。底座与中心块的分体结构，使得底 座能够有更多的颜色选择，可以根据需要做全透明的外观，可以有更多的拓展可能性。
中心块38与底座32扣位连接或卡接连接或榫卯连接或胶粘连接，端子34和切换片35安装在底座32，外力驱使按钮36顺着中心块38的中心槽31的走向上下移动，按钮36在上下移动的过程中对切换片33产生作用力并驱使切换片33变形，以使得切换片33与端子34分离，断开切换片33与端子34的电性连接，从而使得机械轴实现开关功能，如附图10和附图12剖面图。外力撤走后，按钮36在弹簧37的作用下回位，按钮36与切换片33分离，切换片33在自身弹力作用下回位并与端子34接触，导通切换片33与端子34的电性连接。
本实施例的光轴为分体式结构，可任意组合材质多样性搭配和颜色多样性搭配。
请参考图13-20，本发明实施例4包括：
一种分体式底座的机械轴结构，包括具有中心槽41的底座42、与底座42连接并形成腔室的上盖43、端子44、切换片45、驱使切换片45与端子44接通或断开的按钮46、以及驱使按钮46回位的弹簧47，按钮46可相对于中心槽41上下滑动，底座42与中心槽41分体式连接。中心槽41位于中心块48，中心块48与底座42分体式连接。底座42设置有贯通开窗49，中心槽41安装在贯通开窗49。端子44连接在中心块48。切换片45连接在中心块48。
如附图14爆炸图所示，中心块48与底座42为两个独立的部件，故中心块与底座可采用不同的材质制作，由于端子、切换片通过波峰焊固定在中心块上，故中心块对耐高温特性的需求较大，因此中心块可针对性地采用具有耐高温特性的材质制作，而底座对耐高温特性的要求并不高，可采用其他材质制作。此外，由于底座作为外表，对美观性有要求，由于底座与中心块相互分离独立， 可对底座和中心块进行不同颜色的着色设计，甚至还可根据需要做成透明的，极大地丰富了轴体外观设计的可选择空间。
中心块48与底座42扣位连接或卡接连接或榫卯连接或胶粘连接，与实施例3不同，本实施例中，端子44和切换片45安装在中心块48，外力驱使按钮46顺着中心块48的中心槽41的走向上下移动，按钮46在上下移动的过程中对切换片43产生作用力并驱使切换片43变形，以使得切换片43与端子44分离，断开切换片43与端子44的电性连接，从而使得机械轴实现开关功能，如附图18和附图20剖面图。外力撤走后，按钮46在弹簧47的作用下回位，按钮46与切换片43分离，切换片43在自身弹力作用下回位并与端子44接触，导通切换片43与端子44的电性连接。
本实施例的光轴为分体式结构，可任意组合材质多样性搭配和颜色多样性搭配。
