 本发明的实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
实施例：
在本实施例中，提供一种医用台车，包括升降系统，如图1-9所示，其中升降系统包括：套杆1、内滑杆2、第一限位组件3、第二限位组件4和驱动组件5，套杆1套设于内滑杆2外，第一限位组件3包括第一滑轮31，第一限位组件3固定装配于内滑杆2的外壁面，第一滑轮31的轮面抵顶于套杆1的内壁面，第二限位组件4包括第二滑轮41，第二限位组件4固定装配于套杆1内，第二滑轮41的轮面抵顶于内滑杆2的外壁面，第一滑轮31的转动轴和第二滑轮41的转动轴均垂直于内滑杆2的延伸方向，驱动组件5连接套杆1和内滑杆2，驱动组件5用于驱动内滑杆2沿着套杆1移动。
由于第一限位组件3的第一滑轮31抵顶在套杆1的内壁面，第二限位组件4的第二滑轮41抵顶在内滑杆2的外壁面，因此，内滑杆2能够稳定地与套杆1相连，在驱动组件5的驱动作用下，内滑杆2能够在套杆1内相对滑动，从而实现升降，且在内滑杆2滑动的过程中，第一滑轮31在套杆1的内壁面上滚动，第二滑轮41在内滑杆2的外壁面上滚动，因此摩擦力更小，且内滑杆2与套杆1的内壁之间具有间隔，内滑杆2与套杆1之间不会剐蹭，内滑杆2相对套杆1滑动时不易发出声响，本方案的升降结构能使医用台车调节高度时省力、平稳且安静，调节更加方便，更适于医用环境下的使用。
结合图3-6，套管11包括套管11和套帽12，套帽12盖设于套管11一端的端口，套帽12中部开设与内滑杆2匹配的通口121，内滑杆2穿设于通口121内。具体的，套管11的底端可以固定装配在一个底座上，内滑杆2装配在套管11的顶端，内滑杆2的一部分容置于套管11内，第一限位组件3固定装配于内滑杆2的位于套管11内的底端处，医用台车的承载台可以装配在内滑杆2的露出于套管11的顶端，在内滑杆2滑动的过程中，内滑杆2可以从套帽12的通口121处滑出或滑入套管11内，从而带动承载台实现升降，且套帽12盖设在套管11上，可以对套管11的内部进行密封，更加安全。在本实施例中，套管11由型材制成，套管11的外侧具有凹槽，凹槽内可以滑动装配滑块，滑块上可以固定悬挂物品。
第二限位组件4还包括装配片42和装配块43，装配片42固定于套帽12的内壁面，装配片42包括基片421和自基片421边缘延伸出的固定片422，基片421开设与通口121对应的内环口，固定片422垂直于基片421的板面，装配块43固定装配于固定片422，第二滑轮41转动装配于装配块43。具体的，在本实施例中，基片421的内环口与内滑杆2相匹配，因此，基片421装配在套帽12中时，内滑杆2能从内环口穿过，基片421呈矩形环状，即基片421具有两相互平行的长边和两相互平行的短边，基片421的每一个边缘分别延伸出一个固定片422，为了防止装配片42落入套管11内，套管11的内壁设置卡嵌棱112，卡嵌棱112与套管11的内壁之间形成卡嵌槽，卡嵌槽与基片421长边处的固定片422的两侧分别对应，套帽12装配在套管11上时，基片421长边处的固定片422卡嵌在卡嵌槽内。
套帽12内设置卡接片122，卡接片122间隔排列在通口121的外周，卡接片122具有抵顶边缘及自抵顶边缘延伸出的卡凸，基片421开设卡孔4211，卡孔4211间隔排列在内环口的外侧且与卡凸一一对应，基片421抵顶于抵顶边缘且卡凸卡嵌于卡孔4211内；套帽12内设置螺孔柱123，螺孔柱123间隔排列在通口121的外周，螺孔柱123开设螺纹孔，基片421开设与螺孔柱123一一对应的装配孔，基片421通过螺钉与螺孔柱123固定连接。装配片42安装在套帽12上时，将基片421的卡孔4211与卡接片122上的卡凸位置对齐，之后将装配片42按压相套帽12，使基片421抵顶在卡接片122的抵顶边缘上，卡凸嵌设于卡孔4211内，从而保证装配片42的位置准确性，最后用螺钉将基片421与螺孔柱123固定，从而使装配片42稳定地固定连接在套帽12上。在本实施例中，套帽12内设置有十个卡接片122，十个卡接片122间隔排列在通口121的外周，且通口121长边处对应设置三个卡接片122，通口121短边处对应设置两个卡接片122，十个卡接片122的抵顶边缘位于同一平面内，因此，基片421能够紧密地与各卡接片122上的抵顶边缘贴合，以保证装配稳定，套帽12内设置四个螺孔柱123，四个螺孔柱123分别与基片421的四个角处对应，从而保证基片421与套帽12之间的固定稳定；在其他实施例中，套帽12内可以设置四个、五个、六个、七个、八个、九个、十一个、十二个、十三个等的卡接片122，也可以设置两个、三个、五个、六个、七个等的螺孔柱123，具体的数量和位置可以根据需要设置。
装配块43的靠近基片421侧开设第一固定孔，基片421开设与第一固定孔对应的第二固定孔4212，装配块43与基片421之间由螺钉穿过第二固定孔4212后与第一固定孔螺纹连接以进行固定；装配块43的靠近固定片422侧设置固定柱431，固定柱431开设螺纹孔，固定片422的与固定柱431对应处开设第三固定孔4221，装配块43和固定片422之间由螺钉穿过第三固定孔4221后与固定柱431上的螺纹孔螺纹连接以进行固定。具体的，每一装配块43均开设两第一固定孔，从而保证与基片421的连接稳定性，与基片421的短边位置对应的装配块43设置两固定柱431，且套管11的对应位置开设连接孔，安装时螺钉依次穿过连接孔、第三固定孔4221后与固定柱431上的螺纹孔螺纹连接，从而同时实现装配块43与固定片422的固定连接及装配片42与套管11的固定连接，与基片421的长边位置对应的装配块43设置三固定柱431，从而保证该处装配块43的连接稳定性，每一装配块43均转动连接两第二滑轮41，且两第二滑轮41分别位于对应装配块43的运动方向的两侧，在其他实施例中，每一装配块43的运动方向的两侧可以分别转动连接两个、三个、四个等的第二滑轮41。
套帽12内设置定位柱124，定位柱124间隔地环绕于通口121外，套管11的内壁对应处设置限位棱111组，限位棱111组包括两限位棱111，两限位棱111之间形成限位槽，定位柱124内嵌于对应的限位槽内。从而保证套帽12与套管11之间装配时位置的准确性。在本实施例中，套帽12内设置有四个定位柱124，四个定位柱124分别位于套帽12的四个角处，定位柱124呈圆柱形，且定位柱124的端部处具有切角，以便于定位，同一限位棱111组内的两限位棱111的相靠近侧为弧面结构，因此，两限位棱111围成的限位槽的截面为C型，刚好与定位柱124匹配，定位柱124嵌入到限位槽内时即可实现套帽12的定位。
结合图3和图7，第一限位组件3还包括固定框条32和单元座33，固定框条32固定于内滑杆2的外壁面，固定框条32的延伸方向平行于内滑杆2的延伸方向，固定框条32的远离内滑杆2外壁的一侧具有容置槽，容置槽内固定装配至少两单元座33，各单元座33在容置槽的延伸方向上间隔排列，单元座33转动装配至少两第一滑轮31，至少两第一滑轮31在单元座33的长度方向上间隔排列。在本实施例中，容置槽内固定装配两单元座33，每个单元座33内转动装配两第一滑轮31，从而保证内滑杆2相对套管11滑动时流畅而稳定；在其他实施例中，容置槽内可以固定装配三个、四个、五个、六个等的单元座33；在其他实施例中，每个单元座33上可以转动装配三个、四个、五个、六个等的第一滑轮31。
固定框条32包括底条和自底条的两长边缘分别延伸出的固定法兰，底条的两端分别开设第四固定孔，固定法兰垂直于底条的板面，固定法兰之间形成容置槽；第一限位组件3还包括连接杆34，单元座33嵌设于容置槽内，连接杆34的两端分别与固定法兰固定连接，且连接杆34穿过单元座33，从而使单元座33与固定框条32相连接，单元座33具有安装槽，第一滑轮31转动装配在安装槽相对的两内壁之间。在本实施例中，每一单元座33对应一连接杆34，连接杆34穿过单元座33的中部，因此，在内滑杆2相对套管11滑动时，若遇到套管11内壁面不平，单元座33可以相对连接杆34稍微转动而实现缓冲，使得内滑杆2滑动时更加平稳顺畅；当然，次选的也可以每一单元座33对应两根、三根、四根等的连接杆34，使得单元座33与固定框条32之间连接更加可靠。
结合图1-3、8及9，驱动组件5包括连接组件51、气弹簧52和控制机构53，连接组件51固定装配在套杆1内，气弹簧52的缸筒端部连接于连接组件51，气弹簧52的活塞杆的端部与内滑杆2固定连接，气弹簧52的活塞杆的端部具有触发结构521，控制机构53与触发结构521相连，控制机构53用于控制触发结构521以使活塞杆相对缸筒滑动。
