Problems solved by technology
[0003] At present, most of the guardrails on the nursing bed are side-turning, front-turning or plug-in, and their height cannot be adjusted arbitrarily. The operation brings inconvenience to the patient; while the front tipping type cannot let go in the middle of the operation, it will cause the guardrail to drop rapidly, resulting in a decrease in safety and service life; in addition, the plug-in type is not very convenient to operate, and it is more troublesome to use

Embodiment Construction
[0018] like Figure 1~3 As shown, the main body of the movable guardrail of the nursing bed is a four-bar linkage mechanism, and the four-bar linkage mechanism has two mutually parallel horizontal sides, one of which is the bottom frame 3 of the guardrail, and the other side has " A fixed frame 5 with a "shaped cross-section is hinged between two horizontal sides with two connecting rods 4 parallel to each other and equal in length. The four connecting rods form a double crank mechanism, and the guardrail 2 passes through the " The fixed frame 5 with a "shaped cross-section is fixed on the edge of the side frame of the bed surface 1; with a horizontal edge of the four-bar linkage mechanism, that is, the bottom frame 3 of the guardrail as the active part, the guardrail 2 can be moved within the degree of freedom limited by the four-bar linkage. Plane rotation movement within the range. In addition, it also includes a locking mechanism when the guardrail rotates, such as Fig...

The invention relates to a rotating and limiting mechanism of a movable guardrail of a nursing bed. A main body of the movable guardrail is a four-bar linkage and provided with two parallel horizontal sides of which one side is a bottom frame of the guardrail and the other side is a fixed frame with inverted U-shaped cross section, two parallel and isometric connecting rods are articulated between the two horizontal sides, the guardrail is fixed on a side frame edge of a bed surface through the fixed frame with the inverted U-shaped cross section, one horizontal side of the four-bar linkage, i.e. the bottom frame of the guardrail is used as a driving part so as to lead the guardrail to perform plane rotating movement in the range of degree of freedom limited by the four-bar linkage, the rotating and limiting mechanism is arranged between the connecting rods and the fixed frame, that is, a turntable is arranged at the side surface of the fixed frame and provided with a fan-shaped groove, a small cylinder is convexly arranged at the side surface of the connecting rod and is embedded in the fan-shaped groove of the turntable, and the small cylinder follows up with the rotating of the connecting rod so as to limit the rotating range of the connecting rod.
Description
technical field [0001] The invention relates to a protection device installed on a nursing bed, in particular to a rotation limiting mechanism for a movable guardrail of a nursing bed, which belongs to the technical field of medical nursing beds. Background technique [0002] Most of the nursing beds are single beds with a narrow width. In order to prevent patients from accidentally rolling off the bed and causing injuries, a protective device is added to the nursing bed. It is more common to install a protective rail (referred to as a guardrail) on the nursing bed. , to meet the needs of medical care. [0003] At present, most of the guardrails on the nursing bed are side-turning, front-turning or plug-in, and their height cannot be adjusted arbitrarily. The operation brings inconvenience to the patient; while the front tipping type cannot let go in the middle of the operation, which will cause the guardrail to drop rapidly, resulting in a decrease in safety and service li...
