Description

一种病床制动装置 技术领域
本申请涉及病床的技术领域，具体地，主要涉及一种病床制动装置。
背景技术
病床一般指护理床，是根据病人的治疗需要和卧床生活习性而设计的具有多项护理功能的床。
病床在实际的使用过程中，医护人员在必要时需要对其位置进行转移，为此，现有的病床通常安装有脚轮，病床整体通过脚轮支撑在地面上。脚轮上一般还安装有刹车装置，医护人员将病床移动到合适的位置后，通过操作刹车装置对病床进行制动即可将病床的位置锁定。
但是，由于惯性作用，病床当移动到需要的位置后，工作人员只对其中一个脚轮上的刹车进行操作，另外的脚轮并未受到制动，这不能够迅速的使病床稳定下来，从而给病床的使用带来了不便，因此，需要对其进行改进。
申请内容
针对现有技术的不足，本申请提供一种病床制动装置。
本申请公开的一种病床制动装置，包括：连杆组件；所述连杆组件包括第一制动部、第二制动部和连接部，所述第一制动部和所述第二制动部均转动支撑在病床的底架上，并与病床的脚轮相连接；所述第一制动部、所述第二制动部及所述连接部均设置有两个，其中一个所述连接部连接在两个所述第一制动部之间，另外一个所述连接部连接在两个所述第二制动部之间；踏板组件；所述踏板组件安装在所述连杆组件上；传动组件；所述传动组件安装在两个所述连接部之间。
优选地，所述传动组件包括两个安装部和传动部，两个所述安装部分别安装在两个连接部上，所述传动部安装在两个所述安装部之间。
优选地，所述连接部上设置有安装孔，所述安装部上设置有安装板，所述安装板连接在所述安装孔内。
优选地，所述安装部上设置有安装缺口，所述安装板设置在所述安装缺口处，所述安装缺口与所述连接部相贴合。
优选地，所述踏板组件包括插接部和踩踏部，所述插接部连接在所述第一制动部上，所述踩踏部连接在所述插接部上。
优选地，所述踏板组件还包括接触部，所述接触部包括接触板和定位柱，所述踩踏部上开设有定位孔，所述定位柱安装在所述定位孔内。
优选地，所述接触板上设置有多个防滑凸起。
优选地，所述第一制动部为六棱柱结构，所述插接部上开设有插接孔，所述第一制动部穿设在所述插接孔内。
优选地，所述第二制动部为六棱柱结构，所述连接部上开设有连接孔，所述连接孔为六边形孔，所述第一制动部穿设在与其连接的所述连接部的所述连接孔内，所述第二制动部穿设在与其连接的所述连接部的所述连接孔内。
优选地，每个所述插接部上连接有两个所述的踩踏部。
本申请的有益效果在于：
当需要对病床进行制动时，操作人员用脚踩踏任意一个踏板组件的接触部，则接触部能够带动踩踏部及整个踏板组件发生转动，进而带动第一制动部以及与之相连的连接部，与第一制动部相连的连接部转动后，通过安装部和传动部对另一连接部进行传动，从而带动两个第二制动部转动；因此，通过踩踏任意一个踏板组件，即可使两个第一制动部和两个第二制动部同时转动，制动的动作通过第一制动部及第二制动部同时传递至多个脚轮上，实现了多个脚轮同步制动的功能，提高了病床刹车时的稳定性。

为能进一步了解本申请的申请内容、特点及功效，兹例举以下实施例，并配合附图详细说明如下：
参照图1-图3，本申请公开的一种病床制动装置，安装于病床的底架01上，用于对病床的脚轮02进行制动。病床的底架01包括支撑框011和支撑筒012，支撑框011为矩形的金属框架，支撑筒012为圆柱形套筒，支撑筒012固定安装在支撑框011的四角处，支撑筒012设有朝下开口的支撑孔0121，用于连接脚轮02，支撑筒012的侧壁上开设有贯通两个侧壁的穿接孔0122，穿接孔0122用于安装连杆组件2；每个支撑筒012各连接一个脚轮02，脚轮02具有配合部021，配合部021安装在支撑孔0121内，用于和连杆组件2配合以触发制动。

参照图3-图5，连接部23为圆柱形的长杆，连接部23的两端开设有连接孔231，连接孔231为六边形孔且与连接部23同轴设置，连接部23设置有两个，其中一个连接部23连接在两个第一制动部21之间，另外一个连接 部23连接在两个第二制动部22之间，且第一制动部21穿设在与其连接的连接部23的连接孔231内，第二制动部22穿设在与其连接的连接部23的连接孔231内，从而第一制动部21或者第二制动部22转动即能够带动连接部23转动；每个连接部23的中部均设置有安装孔232，安装孔232为盲孔，安装孔232用于和传动组件3相连接。
参照图3-图5，每个第一制动部21上均连接一个上述的踏板组件1，踏板组件1包括插接部11、踩踏部12和接触部13，其中，插接部11为圆柱形结构，插接部11的一端开设有插接孔111，插接孔111为六边形孔，插接部11通过插接孔111连接在第一制动部21背离连接部23的端部；踩踏部12为板状结构，每个插接部11上一体连接有两个踩踏部12，两个踩踏部12沿着插接部11的径向相对设置，并相互平行；每个踩踏部12上均开设有定位孔121，接触部13安装在定位孔121内，接触部13包括接触板131和定位柱132，接触板131同轴固定在定位柱132的端面上，定位柱132穿设在定位孔121内，接触板131背离踩踏部12的表面上设置有多个球状的防滑凸起1311，当操作人员踩踏接触板131时，防滑凸起1311能够提高脚部与接触板131之间的摩擦力，减少打滑的现象发生。
参照图3-图5，传动组件3包括安装部31和传动部32，安装部31为长条形板状结构，安装部31设置有两个，两个安装部31分别安装在两个连接部23上，安装部31的一端设置有弧形的安装缺口311，且安装部31在安装缺口311处一体设置有安装板312，安装板312的形状与连接部23上的安装孔232相配合，安装板312穿设在安装孔232内并与安装孔232过盈连接，安装部31的安装缺口311贴在连接部23的外壁上，使得安装部31与连接部23固定连接并相互贴合，安装部31的表面垂直于连接部23的轴线，当安装部31或者连接部23转动时，二者能带动彼此同步转动；传动部32设置在两个安装部31之间，传动部32为长杆状结构，传动部32的两端均与安装部31转动连接，从而使得传动组件3能够在连杆组件2的两个连接部23之间 传递动力。
本申请的实施原理和有益效果是，当需要对病床进行制动时，操作人员用脚踩踏任意一个踏板组件1的接触部13，则接触部13能够带动踩踏部12及整个踏板组件1发生转动，进而带动第一制动部21以及与之相连的连接部23，与第一制动部21相连的连接部23转动后，通过安装部31和传动部32对另一连接部23进行传动，从而带动两个第二制动部22转动；因此，通过踩踏任意一个踏板组件1，即可使两个第一制动部21和两个第二制动部22同时转动，制动的动作通过第一制动部21及第二制动部22同时传递至多个脚轮02上，实现了多个脚轮02同步制动的功能，提高了病床刹车时的稳定性。
上仅为本申请的实施方式而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理的内所作的任何修改、等同替换、改进等，均应包括在本申请的权利要求范围之内。
