[0030] The fall-preventing sickbed has the folding assembly 2, which can be retracted and opened conveniently, does not affect the patients to get on and off the bed in the retracted state, and prevents the patients from falling in the opened state; and the folding assembly 2 has the long cross bar 21 and the plurality of short bars 22 and 23, wherein the two ends of the short bars 22 and 23 are rotatably connected with the long cross bar 21 and the groove wall of the receiving groove 14, respectively, the short bars 22 and 23 have the same length and are arranged in parallel with each other, and the parallelogram principle is adopted, so that the structure is simple, no space is occupied in the retracted state, and the use is convenient.
[0031] In an embodiment, referring to Figure 6 、 Figure 9 The plurality of short bars 22 and 23 comprises a plurality of first short bars 22 and a second short bar 23, wherein the first short bars 22 and the second short bar 23 are parallel with each other, the second short bar 23 is arranged close to the tail plate 15, and the second short bar 23 is provided with an abutting portion 231 abutting against the tail plate 15 in the opened state of the folding assembly 2.
[0032] The short bars 22 and 23 are arranged as above, the second short bar 23 is provided with a abutting part 231 on the side close to the bed tail plate 15, so that the abutting part 231 abuts against the bed tail plate 15 when the folding assembly 2 starts, and the folding assembly 2 is kept in the open state and is not rotated at will. Moreover, when the folding assembly 2 is retracted, the long horizontal bar 21 and the plurality of short bars 22 and 23 are all located in the accommodating groove 14, and it is not easy to pull them out by using hands or other parts, and the abutting part 231 is arranged to protrude from the accommodating groove 14, so that the folding assembly 2 is pulled out by the abutting part 231 to be opened when used.
[0033] In an embodiment, referring to Figure 6 , Figure 9 , the second short bar 23 is rotationally connected with the groove wall of the accommodating groove 14 through a second short bar rotation shaft 232, the second short bar 23 is provided with a first fixed part 233, the side wall of the accommodating groove 14 is provided with a second fixed part 17, and the second fixed part 17 is located obliquely below the second short bar rotation shaft 232 close to the bed tail plate 15, and the first fixed part 233 and the second fixed part 17 are provided with an elastic member 3 therebetween, so that the folding assembly 2 is kept in the retracted or open state.
[0034] Through the above structure, only one elastic member 3 is needed to keep the folding assembly 2 in the retracted state or the open state.
