The specific embodiment
Below in conjunction with embodiment shown in the drawings the present invention is further described.
Embodiment one: referring to accompanying drawing 1 to shown in the accompanying drawing 5.
A kind of nursing bed elevating mechanism, comprise bedstead 1, be symmetricly set on bedstead 1 below two supporting legs 2, two linking arms 3, be arranged on the adjusting device between supporting leg 2 and the bedstead 1.
One end of two linking arms 3 rotates by first rotating shaft 4 with the middle part of two supporting legs 2 respectively and is connected; Bedstead 1 is provided with four revolving sleeves 5, one group and be fixed on the bedstead 1 in twos of revolving sleeve 5 by bolt 6, the other end of two linking arms 3 is respectively arranged with through hole 7, is equipped with second rotating shaft, 8, the second rotating shafts 8 and revolving sleeve 5 in the described through hole 7 and cooperates linking arm 3 rotated with bedstead 1 and be connected.
Adjusting device comprises the vertical slide rail 9 that is arranged on described bedstead 1 below along the width of bedstead 1, be arranged on the first horizontal slide rail 10 of described bedstead 1 below along the length direction of bedstead 1, be arranged on the second horizontal slide rail 11 of described bedstead 1 below along the length direction of bedstead 1, the longitudinal sliding block 12 that is complementary with vertical slide rail 9, first transverse slider 13 that is complementary with the first horizontal slide rail 10, second transverse slider 14 that is complementary with the second horizontal slide rail 11, first connecting rod 15, second connecting rod 16, be parallel to vertical slide rail 9 and have first end and the electric pushrod 17 of second end.
Vertically slide rail 9, first horizontal slide rail 13, the second horizontal slide rail 14 is fixedly connected on the below of bedstead 1 by the slide rail set bolt, and vertical slide rail 9 is arranged between two supporting legs 2; Electric pushrod 17 is arranged on the below of bedstead 1 and is positioned at same perpendicular with vertical slide rail 9 along the width of bedstead 1, first end of electric pushrod 17 is fixedly connected on the bedstead 1, longitudinal sliding block 12 is set on second end of electric pushrod 17, and fixedly connected by set bolt 18; Identical and the symmetric both sides that are arranged on vertical slide rail 9 of length of the described first horizontal slide rail 10, the second horizontal slide rail 11, first horizontal slide rail 10, the second horizontal slide rail 11 is with vertically slide rail 9 is perpendicular.
One end of first connecting rod 15 is rotatably connected on the longitudinal sliding block 12 by connecting bolt 19, and the other end of first connecting rod 15 is rotatably connected on first transverse slider 13 by connecting bolt 19; One end of second connecting rod 16 is rotatably connected on the longitudinal sliding block 12 by connecting bolt 19, and the other end of second connecting rod 16 is rotatably connected on second transverse slider 14 by connecting bolt 19; Described first transverse slider 13, second transverse slider 14 are rotatably connected on the top of two supporting legs 2 respectively.
