Problems solved by technology
Among them, the first and third types are more common, but the first type needs to be manually disassembled every time a patient gets in and out of bed, which is very inconvenient. The third type is more commonly used in hospitals, which is relatively simple, and does not comply with the load and automatic slow down in the regulations. The second and fourth types are relatively novel guardrails. The second type is vertically telescopic, so the overall processing and installation accuracy are relatively high, and it is difficult to meet the requirements of the second and fourth types of guardrails. Do not pinch your hands; the last one is currently a solution that is perfectly compatible with regulations and requirements from all directions
[0003] At present, in the rotating retractable guardrail, the most common method is to increase the friction by pasting PU or other plastics on both sides of the lower rotating rod, so as to achieve the effect of slowly falling after the switch is released without pinching the hand. With the wear of PU or other plastics, the friction effect will become worse and worse, until finally the friction plate fails, and the overall cushioning effect is not good

The invention discloses a guardrail and a nursing bed. The guardrail comprises an upper protective rod, a lower protective rod, a telescopic rod, a connecting rod mechanism and a buffer mechanism; thetelescopic rod is arranged between the upper protective rod and the lower protective rod; the connecting rod mechanism comprises a first connecting rod and a second connecting rod; one end of the first connecting rod is rotationally connected with the telescopic rod, and the other end of the first connecting rod is rotationally connected with the upper protective rod; one end of the second connecting rod is rotationally connected with the telescopic rod, and the other end of the second connecting rod is rotationally connected with the lower protective rod; the buffer mechanism comprises a linkage piece and a variable resistance piece; the linkage piece is provided with a moving tail end connected with the variable resistance piece; one end of the linkage piece is connected with the secondconnecting rod so as to convert variable-speed rotation of the second connecting rod into variable-speed linear motion of the moving tail end; the variable resistance piece is arranged on the lower protective rod; and the variable resistance piece is configured such that the greater the received speed is, the greater the resistance is. By arranging the buffer mechanism, variable-speed rotation ofthe second connecting rod can be converted into variable-speed linear motion of the moving tail end, so that the guardrail can keep a slower descending effect, and the buffer effect is excellent.
Description
technical field [0001] The invention relates to the technical field of nursing equipment, in particular to a guardrail and a nursing bed. Background technique [0002] In the existing market, whether it is a medical bed or a home-style nursing bed, the guardrails on both sides are necessary accessories. At present, the common guardrails at home and abroad are generally divided into four categories: round tube bending splicing type, two-stage or Three-level vertical telescopic type, medical bed folding type, rotary retractable type. The first and third types are more common, but the first type needs to be manually disassembled every time a patient gets in and out of bed, which is very inconvenient. The third type is more commonly used in hospitals, which is relatively simple, and does not comply with the load and automatic slow down in the regulations. The second and fourth types are relatively novel guardrails. The second type is vertically telescopic, and the overall proce...
