Handrail adjusting device for medical bed based on toothed bar principle

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an armrest adjustment device for medical beds based on the principle of gear rods. Background technique [0002] In order to ensure the safety of the patient, handrails are generally arranged on both sides of the medical bed. In order to facilitate the patient to get out of bed and facilitate the medical staff to care for the patient, the handrails on both sides are generally designed as a foldable structure, but the existing medical bed handrails The size is basically fixed, so the height of the armrest cannot be adjusted, and it cannot meet the requirements of different patients for the height of the armrest. At the same time, the existing adjustable armrest cannot guarantee the stability of the adjusted height during adjustment, and there is a certain degree of safety. Hidden danger. [0003] In order to solve the above problems, the inventor proposed an armrest adjus...
