Description

一种滑轮组件 技术领域
本申请实施例涉及但不限于淋浴房技术领域，具体涉及一种滑轮组件。
背景技术
淋浴房的房门一般是采用滑轮与滑轨配合的结构实现房门的滑动开合，并需要滑轮具有一定的防脱功能。
一些淋浴房虽然具有滑轮防脱功能，但不能实现在滑轮安装后防脱功能自动调节出来，而是在滑轮安装后需要经过多个步骤的人工调节后才能实现防脱功能。在淋浴房实际安装过程中，因多种原因往往没有将滑轮的这个防脱功能调节出来，这样淋浴房在使用一段时间后会出现滑轮跳出轨道的风险，会给用户的生命安全造成严重危害。

详述
本领域的普通技术人员应当理解，可以对本申请实施例的技术方案进行修改或者等同替换，而不脱离本申请技术方案的精神和范围，均应涵盖在本申请的权利要求范围当中。
如图1-图20所示，本申请的实施例提供一种滑轮组件，包括固定座4、设置在所述固定座4上的支架9、设置在所述支架9上并设置成安装在滑轨15(图20中示出)内的滑轮(本实施例的一个示例中，滑轮包括第一滑轮1和第二滑轮7)、转动连接于所述支架9上的摆块2，以及弹性件12。所述支架9上设有第一限位部，所述第一限位部设置成当所述摆块2在所述弹性件12的弹力作用下沿第一方向转动至第一位置时，限制所述摆块2继续转动；所述摆块2设置成在所述滑轮安装于所述滑轨15内后自动转动至所述第一位置，并与所述滑轨15配合以限制所述滑轮脱出所述滑轨15。
如图20所示，本实施例的滑轮组件，摆块2设置成在滑轮(图20中示出了第二滑轮7)安装于滑轨15内后，能够在弹性件12的弹力作用下自动转动至第一位置，并与滑轨15配合以限制滑轮脱出滑轨15。这样，在滑轮安装于滑轨15内后，摆块2自动转动到防脱位置(即所述第一位置)，即防脱功能自动实现，不需要人工多次调节，安装方便，并给用户的生命安全提供了有力的保障。
在一些示例性实施例中，如图18-图20所示，所述摆块2还设置成在所述滑轮安装于所述滑轨15内过程中，能够在所述滑轨15的作用力下克服所 述弹力反向转动(如图19所示)，以使所述滑轮进入所述滑轨15内。如图6所示，本实施例的一个示例中，滑轮包括第一滑轮1和第二滑轮7，第一滑轮1和第二滑轮7可以对称设置在支架9(图1中示出)的两端，摆块2可以转动设置在支架9的中间位置。
在一些示例性实施例中，如图6所示，所述摆块2处于所述第一位置时，所述摆块2的上端高于所述滑轮(在本实施例的一个示例中，滑轮包括第一滑轮1和第二滑轮7)的上端。这样，如图18、图20所示，在滑轮安装于滑轨15的轨道154内后，摆块2可与轨道的内顶面152配合从而限制滑轮脱出滑轨15。
在一些示例性实施例中，如图1-图6所示，所述支架9设置有连接座10，所述摆块2转动连接在所述连接座10上，所述第一限位部设置在所述连接座10上。所述连接座10上相对设置有两个固定板102，所述摆块2对应设有两个连接臂21，两个所述连接臂21通过一转轴13转动连接在两个所述固定板102上。所述弹性件12可以为扭簧，并设置在所述连接座10与所述摆块2之间。本实施例的一个示例中，如图1、图10所示，所述支架9可以包括支架主体90和设置在支架主体90上的连接座10。如图2-图6所示，两个连接臂21可以分别位于两个固定板102的外侧(即两个固定板102的相背离侧)，两个所述固定板102上设有供所述转轴13穿过的轴孔1023，两个所述连接臂21上对应设有设置成与所述转轴13的两端转动连接的轴孔211。
在一些示例性实施例中，如图10、图2-图5所示，所述扭簧(图10中的标号12)可以套设在所述转轴13上并位于两个所述固定板102之间，所述扭簧的一个端脚抵接在所述摆块2上，另一个端脚抵接在所述连接座10上。本实施例的一个示例中，如图2、图3所示，所述摆块2的底部在两个连接臂21之间形成了一个开口槽，所述扭簧位于该开口槽内，开口槽的一侧设有自槽底22向槽口方向延伸的凸出部23。扭簧的一个端脚抵接在所述凸出部23的内侧面上，另一个端脚抵接在连接座10的顶面上。
在一些示例性实施例中，如图4、图5所示，所述第一限位部可以包括设置在所述连接座10上的凸台101。所述摆块2处于所述第一位置时，所述连接臂21的下端面212抵接于所述凸台101上。如图6所示，所述摆块2 处于所述第一位置时，所述连接臂21的下端面212(图3中示出)抵接在凸台101的顶面1011(图5中示出)上，以进行限位。如图3所示，所述连接臂21的下端面212与所述连接臂21的一个侧面圆滑过渡连接(可采用弧形过渡面213进行圆滑过渡)，以在所述连接臂21转动过程中避让所述凸台101，如图12和图15所示。本实施例的一个示例中，如图4、图5所示，两个固定板102的外侧(即两个固定板102的相背离侧)可以均设置有一个所述凸台101，两个凸台101分别与两个连接臂21配合实现限位。
在一些示例性实施例中，如图4、图5所示，所述第一限位部可以包括两个所述固定板102，如图11所示，所述摆块2处于所述第一位置时，所述固定板102的上端面1022(图5中示出)抵接于所述摆块2上。本实施例的一个示例中，如图11所示，所述摆块2处于所述第一位置时，所述固定板102的上端面1022(图5中示出)可以抵接于所述开口槽的槽底22(图3中也有示出)，以限制摆块2继续向第一方向转动。如图5所示，所述固定板102的上端面与所述固定板102的一个侧面圆滑过渡连接(可采用弧形过渡面1021进行圆滑过渡)，以在所述摆块2转动过程中避让所述摆块2，即避让所述开口槽的槽底22，如图14和图17所示。
在一些示例性实施例中，如图8所示，所述摆块2处于所述第一位置时位于所述滑轮(包括第一滑轮1和第二滑轮7)的行走轨迹上。这样，在滑轮安装于滑轨15内后，摆块2处于所述第一位置时摆块2和滑轮两者整体的宽度不至于太大，滑轨15用于容纳摆块2和滑轮的型腔也不需太大，节省空间。本实施例的一个示例中，所述摆块2和所述滑轮(包括第一滑轮1和第二滑轮7)可以均设置在所述支架9的外侧(即远离固定座4的一侧)。
如图1所示，所述固定座4与支架9的连接方式，以及支架9的支架主体90和连接座10的连接方式可以不受限制，三者主要起承载作用。在一些示例性实施例中，如图1-图6所示，所述固定座4可以包括竖直设置的第一支撑板，以及设于第一支撑板同一侧的顶板和底板。所述固定座4的顶板和底板上均设有一个固定孔，两固定孔内穿设有螺栓6，螺栓6端部通过固定座4的顶板上的螺母3紧固。固定座4的一侧可以设有用于容置玻璃(实际应用中，本实施例的滑轮组件可以应用在淋浴房的房门中，此玻璃可以是淋 浴房的玻璃房门)的容置槽，玻璃通过设置在容置槽侧壁上的螺栓5顶紧。可以在第一支撑板的另一侧设置第二支撑板，第一支撑板与第二支撑板两者的顶端连接从而在两者之间形成所述容置槽。如图1所示，支架9包括支架主体90和设置在支架主体90上的连接座10，支架主体90可以水平设置，支架9通过支架主体90的中部设置的螺纹孔螺纹连接在所述螺栓6上。支架9外侧的两端(即支架主体90的远离所述第一支撑板的一侧的两端)均转动连接一个滑轮，分别为第一滑轮1和第二滑轮7，第一滑轮1和第二滑轮7分别通过一个螺钉(螺钉14和螺钉8)转动安装在支架9上。如图10所示，支架9外侧的中间位置(即支架主体90的远离所述第一支撑板的一侧的中间位置)设有方形凸台91，方形凸台91内设有螺纹孔。如图5、图10所示，所述连接座10的侧面设有与所述方形凸台91配合的方形槽103，采用螺钉11穿过连接座10上设置的固定孔104将连接座10固定在所述方形凸台91上，螺钉11的端部旋紧在方形凸台91内的螺纹孔内。连接座10的顶面上相对设有两个所述固定板102。
在一些示例性实施例中，将摆块2的上端与滑轮的下端之间的垂直距离定义为A x。在没有施加外力的情况下摆块2由第一限位部限制在第一位置，该第一位置为摆块2的防脱位置，也是摆块2的初始位置。当摆块2处于第一位置时，A x＝A1(如图10所示)，此时A x的值最大，此时滑轮组件的整体状态可参见图6-图11。当摆块2在外力推动下反向转动至某个中间位置时，A x＝A2(如图13所示)，此时滑轮组件的整体状态可参见图12-图14。当摆块2在外力推动下反向转动至极限位置时，A x＝A3(如图16所示)，此时A x的值最小，此时滑轮组件的整体状态可参见图15-图17。其中，A1>A2>A3。
如图18所示，实际应用时需将滑轮组件安装在滑轨15上，滑轨15设有用于容置滑轮的型腔，型腔内的底面上形成有供滑轮(包括第一滑轮1和第二滑轮7)滑动的轨道154，型腔内的顶面即为轨道的内顶面152，型腔一侧的开口形成滑轨15的轨道入口。轨道入口的高度尺寸为B，尺寸B设计为比A1小，比如B＝A1-3.2；滑轮运行的高度尺寸(即轨道154的底面与轨道的内顶面152之间的高度尺寸)为C，尺寸C设计为比A1稍大，比如C＝A1+0.5。本文中所有尺寸的单位可以均为毫米。
如图18-图20所示，在滑轮组件安装过程中，轨道入口的顶边151会对摆块2施加一个推力F，摆块2在该推力的作用下克服所述弹性件12的弹力反向转动，当摆块2反向转动至A x＝B时，滑轮可以进入所述滑轨15的轨道154内。在滑轮进入轨道154内后，所述推力F就没有了，摆块2在弹性件12的弹力作用下就可以沿第一方向自动转动至第一位置(第一位置时弹性件12还可以具有弹力，使得摆块2有沿第一方向转动的趋势)，此时，A x＝A1>B，从而可以防止滑轮脱出轨道154。此外，当向外水平拉动滑轮时，因没有促使摆块2反向转动的力，故摆块2是不会反向转动的，故滑轮不能脱出轨道154。此外，可以根据实际需要设计B、C和A1的尺寸，本实施例的一个示例中将C和A1的尺寸差设计为0.5mm，因该0.5mm的间隙远远小于行业运行间隙(1mm以上)，故滑轮运行过程中上下晃动小，运行动作更加平稳。
如图21-图37所示，本申请的另一实施例提供一种滑轮组件，包括固定座4、设置在所述固定座4上的支架9、设置在所述支架9上并设置成安装在滑轨15(图36中示出)内的滑轮(本实施例的一个示例中，滑轮包括第一滑轮1和第二滑轮7)、转动连接于所述支架9上的摆块(本实施例的一个示例中，摆块包括第一摆块16和第二摆块19)，以及弹性件18。所述支架9上设有第一限位部，所述第一限位部设置成当所述摆块在所述弹性件18的弹力作用下沿第一方向转动至第一位置时，限制所述摆块继续转动；所述摆块设置成在所述滑轮安装于所述滑轨15内后自动转动至所述第一位置，并与所述滑轨15配合以限制所述滑轮脱出所述滑轨15。
如图36所示，本实施例的滑轮组件，摆块(图36中示出了第一摆块16)设置成在滑轮(图36中示出了第一滑轮1)安装于滑轨15内后，能够在弹性件18的弹力作用下自动转动至第一位置，并与滑轨15配合以限制滑轮脱出滑轨15。这样，在滑轮安装于滑轨15内后，摆块自动转动到防脱位置(即所述第一位置)，即防脱功能自动实现，不需要人工多次调节，安装方便，并给用户的生命安全提供了有力的保障。
在一些示例性实施例中，所述支架9上还可以设有第二限位部，所述第二限位部设置成将所述摆块限制在第二位置，所述摆块处于所述第二位置时所述弹性件18具有弹力；所述摆块还设置成在所述滑轮安装于所述滑轨15 内过程中，能够在所述滑轨15的作用力下脱离所述第二限位部的限制后转动(即靠弹性件18的弹力自动沿第一方向转动)至所述第一位置。
在一些示例性实施例中，所述摆块上设有设置成与所述第一限位部配合的第一限位配合部，以及设置成与所述第二限位部配合的第二限位配合部；所述第二限位配合部和所述第二限位部中的任一或全部设置成在所述滑轨15的作用力下(在所述滑轮安装于所述滑轨15内过程中，摆块受到滑轨15的作用力而使所述第二限位配合部和所述第二限位部之间产生相互作用力)，能够发生弹性变形并使所述第二限位配合部通过所述第二限位部，从而使所述第二限位配合部脱离所述第二限位部的限制。
在一些示例性实施例中，如图28所示，所述摆块(如图22和图23所示的第一摆块16)包括摆臂161，所述摆臂161转动设置在所述支架9的一侧，所述摆臂161上设有所述第一限位配合部和所述第二限位配合部；所述弹性件18为卷簧，所述卷簧设于所述摆臂161和所述支架9之间。本实施例的一个示例中，如图28所示，所述支架9相对所述摆臂161的一侧设有凸出轴95(图24中也示出)，所述摆臂161设有与所述凸出轴95转动配合的轴孔1613(图22和图23中示出)，所述凸出轴95伸出所述轴孔1613的一端固定有螺钉17，螺钉17的端部旋紧于凸出轴95内设置的螺纹孔内。所述卷簧(图28中的标号18)可以套设在所述凸出轴95外部，所述支架9侧部围绕所述凸出轴95设有第一卡槽96(图24中示出)，所述摆臂161的侧部围绕所述轴孔1613设有第二卡槽1614(图22中示出)，所述卷簧可以限制于所述第一卡槽96和所述第二卡槽1614围成的容置腔内。
在一些示例性实施例中，如图24所示，所述第一限位部可以包括设置在所述支架9上的第一凸台94，所述第二限位部可以包括设置在所述支架9上的第二凸台92；如图22所示，所述第一限位配合部包括设置在所述摆臂161上的挡板1611，所述第二限位配合部包括设置在所述挡板1611上的凸起1612；所述摆块转动至所述第一位置(图25所示状态)时，所述挡板1611抵接在所述第一凸台94上。本实施例的一个示例中，如图22所示，所述挡板1611设置在摆臂161相对于支架9的一侧面上，挡板1611可以呈弧状，所述凸起1612设置在挡板1611相对于支架9的侧面上。
在一些示例性实施例中，如图24所示，所述支架9上还可以设有第三限位部93，所述第三限位部93设置成在所述摆块从所述第二位置反向(即与第一方向相反的方向)转动至设定位置时抵接在所述挡板1611上。本实施例的一个示例中，第三限位部93可以包括第三凸台。
在一些示例性实施例中，如图22-图26所示，所述摆块还可以包括连接于所述摆臂161一端的顶板162(图22和图23中示出)，如图26所示，所述摆臂161(图22和图23中示出)的另一端转动设置在所述支架9上。所述摆臂161和所述滑轮(图26示出了第一滑轮1)分别设置在所述支架9相对的两侧，所述顶板162延伸至所述滑轮所在的所述支架9的一侧，所述摆块处于所述第一位置(图26所示的状态)时所述顶板162的顶面高于所述滑轮(比如图26示出的第一滑轮1)的上端。如图36所示，在滑轮(比如图36示出的第一滑轮1)安装于滑轨15的轨道154(图18示出)内后，摆块的顶板162与轨道的内顶面152配合可以限制滑轮脱出轨道154。
在一些示例性实施例中，如图36、图37所示，所述顶板162的顶面上可以设有凸筋1621(图22和图23也示出)，所述凸筋1621偏心设置并设置成在所述摆块(图36示出了第一摆块16)处于所述第一位置时，当受到所述滑轨15向下的作用力时产生使所述摆块向所述第一方向转动的力矩。本实施例的一个示例中，如图37所示，经过摆块(图37示出了第一摆块16和第二摆块19)的转动中心(即所述凸出轴95的中心轴线)的竖直面定义为中心面t，凸筋1621偏心设置即凸筋1621所在的竖直面偏离中心面t设置，则当摆块处于所述第一位置时，当凸筋1621受到所述滑轨15向下的作用力F1时，F1是使摆块向所述第一方向转动的力，与弹性件18促使摆块向第一方向转动的趋势是一致的，因此摆块不会反向转动。
在一些示例性实施例中，如图21、图25所示，所述固定座4和支架9的连接方式不受限制，两者的连接方式可与图1-图20所示的实施例相同。固定座4的结构可以与图1-图20所示的实施例中的固定座4的结构相同，如图21、图25所示，所述固定座4的顶板和底板上均设有一个固定孔，两固定孔内穿设有螺栓6，螺栓6端部通过固定座4的顶板上的螺母3紧固。固定座4的一侧设有用于容置玻璃(实际应用中，本实施例的滑轮组件可以 应用在淋浴房的房门中，此玻璃可以是淋浴房的玻璃房门)的容置槽，玻璃通过设置在容置槽侧壁上的螺栓5顶紧。支架9可以水平设置，支架9通过其中间位置设置的螺纹孔螺纹连接在所述螺栓6上，支架9外侧(远离固定座4的一侧)的两端均转动连接一个滑轮，分别为第一滑轮1和第二滑轮7，第一滑轮1和第二滑轮7可以对称设置，第一滑轮1和第二滑轮7均通过一个螺钉(螺钉14和螺钉8)转动安装在支架9上。支架9内侧(靠近固定座4的一侧)的两端均转动连接一个摆块，分别为第一摆块16和第二摆块19，第一摆块16和第二摆块19可以对称设置。如图24所示，支架9的顶面上设有第一凸台94，支架9的底面上设有第三凸台，支架9端部的顶面与底面之间的弧状连接面上设有第二凸台92。
在一些示例性实施例中，将摆块的上端与滑轮的下端之间的垂直距离定义为A x。如图31、图32所示，摆块(包括第一摆块16和第二摆块19)的初始位置为第二位置，此时，如图32所示，摆块的上端低于滑轮(包括第一滑轮1和第二滑轮7)的上端，摆块的下端平齐于或稍微低于滑轮的下端，滑轮的高度尺寸为A(如图33所示)，此时A x约等于A；如图28所示，摆块处于第一位置(即防脱位置)时，A x＝A1，此时A x的值最大。
在一些示例性实施例中，实际应用时可以将滑轮组件安装在如图18所示的滑轨15上。如图18所示，滑轨15设有用于容置滑轮的型腔，型腔内的底面上形成有供滑轮(包括第一滑轮1和第二滑轮7)滑动的轨道154，型腔内的顶面即为轨道的内顶面152，型腔一侧的开口形成滑轨15的轨道入口。轨道入口的高度尺寸为B，尺寸B设计为比A1小，尺寸B等于或稍大于滑轮的高度尺寸A，比如B＝A1-3.2；滑轮运行的高度尺寸(即轨道154的底面与轨道的内顶面152之间的高度尺寸)为C，尺寸C设计为比A1稍大，比如C＝A1+0.5。
在一些示例性实施例中，如图35所示，在滑轮组件安装过程中，轨道入口的底边153会对位于所述第二位置(即初始位置)的摆块(图35示出了第一摆块16)的下端(可以为顶板162)施加一个推力，该推力促使摆块脱离第二限位部(可以为第二凸台92)的限制后，摆块在弹性件18的弹力作用下自动转动至第一位置，如图36所示，此时滑轮(图36示出了第一滑轮1) 安装在滑轨15的轨道154(图18中示出)内，此时，由于A1>B，从而可以防止滑轮脱出轨道154。如图37所示，滑轮组件在实际运行中，如果发生向上晃动，则摆块的顶板162上的凸筋1621(图22和图23中示出)会碰触到轨道的内顶面152(图18中示出)，当凸筋1621受到轨道的内顶面152向下施加的作用力F1时，F1是使摆块向所述第一方向转动的力，与弹性件18促使摆块向第一方向转动的趋势是一致的，因此摆块不会反向转动，故A x始终等于A1并大于B，故始终能防止滑轮脱出轨道154。此外，可以根据实际需要设计B、C和A1的尺寸，本实施例中将C和A1的尺寸差设计为0.5mm，因该0.5mm的间隙远远小于行业运行间隙(1mm以上)，故滑轮运行过程中上下晃动小，运行动作更加平稳。
在本申请实施例的描述中，除非另有明确的规定和限定，术语“连接”、“固定连接”、“安装”、“装配”应做广义理解，例如，可以是固定连接，或是可拆卸连接，或一体地连接；术语“安装”、“连接”、“固定连接”可以是直接相连，或通过中间媒介间接相连，或是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据实际情况理解上述术语在本申请实施例中的含义。
