Detailed ways

The present invention will be described in detail below in conjunction with accompanying drawing and specific embodiment:

As shown in Figure 1, a kind of multifunctional nursing bed of the present invention comprises bed frame 1, and bed frame 1 is the frame structure that is rectangular parallelepiped, and bed frame 1 top surface is along the length direction of bed frame 1 by moving from left to right. The hinges are sequentially connected to the back support board 2, the buttock support board 3, the thigh support board 4 and the calf support board 5, thereby forming a modular spliced bed board, which is convenient for the flexible action of the nursing bed. The top frame of the bed frame 1 is horizontally provided with a beam along the width direction of the bed frame 1, and the beam divides the top frame of the bed frame into a back support plate installation frame and a buttock support plate installation frame; the back support plate 2 is horizontally arranged on the back support plate The buttock support plate 3 is horizontally arranged in the buttock support plate installation frame through bolts, and the bed frame 1 on both sides of the buttock support plate 3 is provided with foldable handrails 6. A tray 7 is placed between the two armrests 6, the thigh support 4 and the calf support 5 are hinged to each other, and the other side of the thigh support 4 is hinged to the end of the bed frame 1 close to the buttock support installation frame through a living hinge; A back lifting mechanism 8 is provided at the bottom of the support board 2 , and a bending leg mechanism 9 is provided below the thigh support board 4 and the calf support board 5 .

Specifically, as shown in Figure 2, the back support plate 2 of a multifunctional nursing bed of the present invention is composed of three symmetrical support plates connected by living hinges, the middle support plate is the main back plate 10, and the two sides are respectively The side protection boards are specifically the right side protection board 11 and the left side protection board 12. A linear slide rail 13 is fixed in the center of the back of the main backplane 10 along its length direction, and a first slide block 14 is housed on the linear slide rail.

As shown in Figures 1, 3 and 4, a back-lifting mechanism 8 of a multifunctional nursing bed of the present invention includes a first stepping electric push rod 16 installed on the first carrier frame 15 below the bed frame 1, the first The left end of the stepping electric push rod 16 is hinged with the first connecting rod 17, and the left end of the first connecting rod 17 is hinged with the second connecting rod 18, and the left end of the second connecting rod 18 is hinged with the lower acute angle supporting point of the triangular bracket 19. The right-angle support point of support 19 is movably hinged on the support beam 20, and the support beam 20 is positioned at the back support plate 2 and is arranged below one end of the crossbeam, and the two ends of the support beam 20 are all fixed on the bed frame 1, and the upper acute angle support of the triangle support 19 Point and the first slide block 14 movable hinges, the upper acute angle support point of tripod 19 is also fixed with the arc strut 21 that is perpendicular to tripod 19, and arc strut 21 is L-shaped, away from a section of tripod 19 toward side The protection plate bends to form an arc section 22, and the upper end of the arc section 22 is also equipped with a freely rotatable roller 23, which is mounted on the back side of the side protection plate by rolling. As the first step electric push rod 16 is pushed out to the left, the triangular bracket 19 will rotate clockwise around the lower acute angle support point on the support beam 20, and then push the first slider 14 to approach the support beam along the linear slide rail 13 20 direction movement, and then the back support plate 2 is lifted. Simultaneously, the roller 23 of the arc section 22 fixedly connected with the tripod 19 also slides up with the first slider 14 and moves synchronously on the back side of the right side protection plate 11 and the left side protection plate 12 in a direction close to the support beam 20, Because the arc section 22 is curved, the right side protection board 11, the main backboard 10 and the left side protection board 12 are automatically synchronized to form a concave shape, thereby preventing the patient from falling sideways because the back support board 2 is lifted, and The curvature of the concave shape will automatically increase with the increase of the lifting angle of the back support plate 2, so as to effectively protect the back lifting, and the structure is ingenious and very ergonomic. Conversely, when the first electric push rod 16 is retracted to the right, the back support plate 2 will rotate counterclockwise along with the tripod 19 around it and the lower acute angle support point installed on the support beam 20 will be put down until it is flat.
