[0001] The utility model belongs to the technical field of guardrails for nursing beds, and particularly relates to a guardrail for a nursing bed which is convenient for retracting, extending and adjusting. Background Art

[0002] A nursing bed is one of the essential instruments in medical and health places, mainly used in the wards of clinics, hospitals and other places for patients' treatment or post-operative rest and rehabilitation, facilitating medical staff's observation and inspection as well as the operation and use by family members. An ordinary nursing bed consists of components such as a bed body, a bed body support, movable wheels and a guardrail.

[0003] Currently, most of the existing guardrails are foldable parallelogram structures to facilitate patients getting on and off the bed. However, the overall size of the guardrail is fixed and cannot be adjusted according to the actual use situation. When hospital beds are in short supply, some children need to use ordinary nursing beds. The distance between the two ends of the guardrail of an ordinary nursing bed and the head and tail of the bed is relatively large. When children move on the nursing bed, the guardrail cannot provide good protection for them, making it easy for children to fall off the nursing bed during activities, posing a safety hazard and resulting in the inability of ordinary nursing beds to adapt to the use of children, thus limiting the scope of use of the nursing bed.

[0004] In view of the above problems, we propose a guardrail for a nursing bed which is convenient for retracting, extending and adjusting. Content of the Utility Model
