The nursing bed that so sets up can realize the effect of bending the leg on the one hand through the leg bending mechanism that sets up detachable at bed body first half, promotes by caregiver lower half blood circulation, alleviates by caregiver health partial pressure, avoids body partial pressurized to lead to bedsore to breed, and the effect of wheelchair can be realized after the separation of on the other hand leg bending mechanism, conveniently removes and is cared for by the caregiver, makes by the caregiver carry out the health with the help of leg bending mechanism and takes exercise and participate in social activity.
Specifically, as shown in fig. 2, a first guide rail is disposed at the bottom of the first curved leg plate 3, a second guide rail is disposed at the bottom of the second curved leg plate 4, and when the first curved leg plate 3 and the second curved leg plate 4 are horizontally coplanar, the first guide rail and the second guide rail are in the same direction, and the directions of the first guide rail and the second guide rail are the same as the direction of the bed body (the front-back direction is the direction of the bed body); the second transmission assembly comprises a first rotating shaft 8, a first coupler 9 and a first connecting rod 5; a first end of the first rotating shaft 8 is rotatably installed on the installation frame, and a second end of the first rotating shaft 8 is fixedly connected with a power output end of the second power source through a first coupler 9; the first end of the first connecting rod 5 is fixedly connected to the first rotating shaft 8, the second end of the first connecting rod 5 is rotatably connected with a first sliding block, the first sliding block is connected with the first guide rail in a sliding mode, and the first sliding block moves linearly along the first guide rail; first transmission assembly includes second connecting rod 6 and push rod, the first end of second connecting rod 6 is articulated with first connecting rod 5, the second end of second connecting rod 6 is articulated with the first end of push rod, the first end of push rod is rotated and is connected with the second slider, second slider and second guide rail sliding connection, the second slider is linear motion along the second guide rail, the second end of push rod is articulated with the inside first dead lever 23 of installation frame, the power take off end and the push rod fixed connection drive push rod of first power supply are linear motion.
Further, the first power source is an electric motor (not shown) fixed at the second end of the push rod, and the electric motor and the push rod are combined to form a first electric push rod 7; the second power supply is double-shaft motor 10, the pivot still includes the second pivot, the shaft coupling still includes the second shaft coupling, the first shaft coupling 9 of double-shaft motor 10's first transmission shaft fixed connection, the second shaft coupling and the second pivot are connected gradually to double-shaft motor 10's second transmission shaft, the arrangement of second transmission shaft one side of double-shaft motor 10 is symmetrical about the transverse axis (transverse axis refers to width direction's axis) of double-shaft motor 10 with arranging on one side of the first transmission shaft. Therefore, on one hand, the structure is simplified, the production feasibility is improved, and on the other hand, the due effect of the leg bending mechanism is ensured.
Preferably, as shown in fig. 1, the nursing bed further comprises a back support mechanism, and a second mounting opening for mounting the back support mechanism is formed in the front half part of the bed plate; the back supporting mechanism comprises a back supporting plate 11, a third connecting rod 12 and a second electric push rod 13, one end of the back supporting plate 11 is hinged with the end part of the second mounting opening close to the middle part of the bed plate, a third guide rail is arranged at the bottom of the back supporting plate 11, the back supporting plate 11 is rotated to be coplanar with the bed plate, the back supporting plate 11 fills the second mounting opening, and meanwhile, the direction of the third guide rail is the same as that of the bed body; the first end of third connecting rod 12 rotates and is connected with the third slider, third slider and third guide rail sliding connection, and the second end of third connecting rod 12 is articulated with bedstead 1 inside second dead lever 18, and the rectangular hole has been seted up at the middle part of third connecting rod 12, and the first power take off end fixedly connected with fourth slider of second electric putter 13, fourth slider sliding connection are downthehole in rectangular, and the stiff end and the bedstead 1 fixed connection of second electric putter 13. Thus, on one hand, the pressure on the back of the cared person is relieved, the blood circulation on the back is promoted, and on the other hand, the daily activities of the cared person, such as eating and reading are facilitated.
Specifically, when the nursed needs to back up, the second electric push rod 13 is started, the fourth slider fixed by the power output end of the second electric push rod 13 pushes the first end of the third connecting rod 12 to rotate around the second fixing rod 18, the third slider rotationally connected with the first end of the third connecting rod 12 is driven to slide from the initial end to the other end in the third guide rail, and then the back supporting plate 11 rotates upwards around the connecting end of the back supporting plate and the second mounting opening, so that the back supporting effect is realized. In the process that the fourth sliding block pushes the first end of the third connecting rod 12 to rotate around the second fixing rod 18, the fourth sliding block slides relatively in the long strip hole in the middle of the third connecting rod 12.
