The invention discloses a
handrail adjusting device for a medical
bed based on a toothed bar principle, and relates to the technical field of medical appliances. The
handrail adjusting device comprises a positioning frame, wherein a fixing bracket is movably connected with the front side of the positioning frame; five fixing seats are fixedly connected above the fixing bracket; the specifications and dimensions of the five fixing seats are the same; the distance between two adjacent fixing seats is the same; and the distance is greater than the length of a movable rod. The
handrail adjusting device for the medical
bed based on the toothed bar principle has the beneficial effect that through a push rod, a rack, a half gear and a
ratchet, the device can be highly stabilized after adjustment. Compared with the existing products, the shortcoming of high
instability after adjustment is solved, the safety
hazard that is probably caused by the shortcoming is avoided, and the safety of a patient during use is ensured. Through the fixing seats, the movable rod, a movable seat, a blocking rod and a self-
locking mechanism, the height of the device is adjustable, the requirements of different patients for the height of a handrail are met, and the users of the device are increased.
