Medical cart with intelligent safety lock
The invention relates to a medical cart with an intelligent safety lock. Drawer grids are provided with locking blocks; an eccentric wheel structure is provided with an eccentric shaft and connected with a lock rod, and a driving structure drives the eccentric wheel structure to rotate forwards and backwards to drive the lock rod to ascend and descend to abut against or be separated from the lock block so as to achieve locking or unlocking action; and a mechanical switch structure comprises a switch knob and a rotary push block, and the rotary push block is provided with a linkage groove for the eccentric shaft to move. The medical cart can drive the eccentric wheel structure to rotate forwards and backwards through the driving structure in the normal working state so as to achieve intelligent unlocking, when intelligent unlocking fails, the eccentric shaft can be rotated by rotating the switch knob so as to achieve manual mechanical unlocking, and when intelligent unlocking and manual mechanical unlocking fail, the drawer grids can be pulled through external force to enable the lock rod to flatten the locking blocks, forced unlocking is achieved, the medical cart has three unlocking modes, it is guaranteed that the drawer grids can be unlocked and opened for medicine taking during rescue, the use safety of the medical cart is improved, and the medical cart is suitable for emergency situations.
本发明涉及一种具有智能安全锁的医疗推车，抽屉格设有锁块；偏心轮结构设有偏心轴并连接有锁杆，驱动结构驱动偏心轮结构正反转动带动锁杆升降与锁块抵接或者分离，以实现锁定或者解锁动作；机械开关结构包括开关旋钮和旋转推块，旋转推块设有供偏心轴活动的联动槽。本发明的医疗推车在正常工作状态下可通过驱动结构驱动偏心轮结构正反转动以实现智能解锁，当智能解锁失效时，可通过旋转开关旋钮使偏心轴转动以实现手动机械解锁，当智能解锁和手动机械解锁失效时，可通过外力拉动抽屉格使锁杆将锁块拉平，实现强行解锁，使得本发明的医疗推车具备三种解锁方式，确保在抢救时能够解锁打开抽屉格进行取药，提高产品使用安全性，适用于紧急情况。
