[0030] Example:

[0031] Reference Figure 1-Figure 6 , the embodiment of the utility model provides a lower limb care bed, comprising a bed body 1, and further comprising: two strip grooves 2, arranged at the end of the bed body 1 and parallel to the long side of the bed body 1;

[0032] A bottom plate 3 is slidably installed in each strip groove 2, and a U-shaped plate 4 with an opening facing upward is fixedly installed on each bottom plate 3, and the number of U-shaped plates 4 on each bottom plate 3 is four groups (the distributed four-group design is to ensure that most parts of the legs can be massaged); a reciprocating part for driving the bottom plate 3 to reciprocate is provided at the bottom of the bed body 1; a first roller 5 is rotatably installed between the inner walls of the U-shaped plate 4;

[0033] Among them, both sides of the U-shaped plate 4 are provided with device grooves 6, and a rocker arm 8 is rotatably installed in each device groove 6 through a rotating rod 7. The upper ends of the two groups of rocker arms 8 are rotatably installed with second rollers 9, and the outer walls of the first roller 5 and the second roller 9 are fixedly connected with protrusions 10 for pressing the legs. The materials of the first roller 5, the second roller 9 and the protrusion 10 are all silicone (the silicone structural material of the first roller 5, the second roller 9 and the protrusion 10 is to improve the comfort of the massage process), the two second rollers 9 and the first roller 5 form a V-shaped structure, and the U-shaped plate 4 is provided with an opening and closing part for driving the lower ends of the two rocker arms 8 to move closer to and away from each other.

[0034] Specifically, when in use, the patient lies flat on the bed 1, and places the two legs on the two rows of first rollers 5 respectively. At this time, the second rollers 9 on both sides of the first roller 5 will be stuck on both sides of the legs, and then the reciprocating part will drive the bottom plate 3 to slide back and forth along the strip groove 2, and the bottom plate 3 will drive the U-shaped plate 4 to slide back and forth, and the U-shaped plate 4 will drive the first roller 5 to roll back and forth under the patient's legs, and drive the second rollers 9 on both sides to roll back and forth on both sides under the legs. During rolling, the protrusions 10 on the outer walls of the first roller 5 and the second roller 9 will press on the surface of the legs, so as to achieve leg massage with good sustainability, thereby effectively improving blood circulation in the lower limbs and preventing the deterioration of lower limb edema;

[0035] During this period, the opening and closing part intermittently presses the lower end of the swing rod 8 toward both sides. When pressed, the lower ends of the swing rods 8 on both sides will move away from each other. At this time, the swing rods 8 on both sides will drive their top ends to move closer to each other through the rotating rod 7, thereby driving the second rollers 9 on both sides to squeeze the patient's legs. When the opening and closing part no longer presses the swing rods 8 on both sides, the pressure of the patient's legs will cause the swing rods 8 to swing in the opposite direction and reset, so that the patient's legs can be subjected to an action similar to manual leg massage, so as to better relieve lower limb edema.

[0036] In practice, the patient can also lie prone on the bed 1, and the upper end surface of the patient's legs can be massaged at this time, so that the care of the lower limbs is more comprehensive.

[0037] The reciprocating part in the lower limb care bed includes a driving motor 15 fixedly mounted on the bottom of the bed body 1, and a reciprocating screw 16 is fixedly mounted on the output shaft of the driving motor 15; wherein, the outer wall of the reciprocating screw 16 is threadedly connected with a reciprocating plate 17 slidably connected to the bottom of the bed body 1, and the reciprocating plate 17 is fixedly connected to the bottom plate 3. It can be seen from the analysis of the above technical solution that the above structure can realize the reciprocating rolling action of the first roller and the second roller under the patient's legs.

[0038] Specifically, when in use, the drive motor 15 is started, and the drive motor 15 can drive the reciprocating screw 16 to rotate, and the reciprocating screw 16 will drive the reciprocating plate 17 to slide back and forth along the long side of the bottom of the bed 1, and drive the bottom plate 3 to slide back and forth in the strip groove 2.

[0039] In order to enable the second rollers on both sides to squeeze and massage the patient's legs, the embodiment of the present application also designs the following technical scheme; the opening and closing part in the lower limb care bed includes a double-headed threaded rod 11 rotatably connected to the bottom of the U-shaped plate 4, and the threads at both ends of the double-headed threaded rod 11 have opposite rotation directions; wherein, both ends of the double-headed threaded rod 11 are threadedly connected to a slide plate 12, and the two slide plates 12 are slidably connected in the U-shaped plate 4, and the lower ends of the two rocker rods 8 are respectively attached to the two sides of the two slide plates 12, and a linkage component for driving the double-headed threaded rod 11 to rotate reciprocally is provided in the strip groove 2.

[0040] Specifically, when the U-shaped plate 4 slides back and forth in the strip groove 2, the linkage assembly will drive the double-headed threaded rod 11 to rotate back and forth in the U-shaped plate 4, that is, to rotate forward and reverse indirectly, so that the slides 12 on both sides will indirectly approach and move away. When the two slides 12 move away from each other, they will press the lower ends of the rocker arms 8 on both sides, and the lower ends of the rocker arms 8 on both sides will move away from each other, and their upper ends will move closer to each other.

[0041] The linkage assembly includes a driven gear 13 fixedly mounted at both ends of the double-threaded rod 11, and multiple racks 14 arranged at equal intervals are fixedly mounted on both sides of the strip groove 2, and two sets of racks 14 are respectively arranged on the upper and lower sides of the driven gear 13; when the two driven gears 13 move along the strip groove 2, the two driven gears 13 are meshed with the racks 14 on both sides in turn. It can be seen from the analysis of the above technical solution that through the action of the linkage assembly, the double-threaded rod can be intermittently rotated forward and reversely, achieving the structural basis for the technical purpose.

[0042] Specifically, when the U-shaped plate 4 slides along the strip groove 2, the U-shaped plate 4 will drive the driven gears 13 on both sides to move synchronously in the strip groove 2, and the driven gears 13 on both sides will mesh with the racks 14 on both sides in turn, that is, when one of the driven gears 13 is meshed with the rack 14 on one side, the driven gear 13 on the other side will not mesh with the rack 14 on the other side; conversely, when the driven gear 13 on the other side is meshed with the rack 14, the former driven gear 13 will not mesh with the rack 14, and because the two groups of racks 14 are respectively located at the upper and lower ends of the driven gear 13; therefore, the racks 14 on both sides will cause the two groups of driven gears 13 to rotate in opposite directions, so the driven gears 13 on both sides that rotate in turn will indirectly drive the double-headed threaded rod 11 to rotate forward and reverse.

[0043] In order to achieve the technical purpose of making the first roller and the second roller fit more closely to the legs, the embodiment of the present application adopts the following scheme, that is, the diameters of the first roller 5 and the second roller 9 from the two ends to the middle gradually decrease; that is, the first roller 5 and the second roller 9 are thinner in the middle and thicker at the two ends, so that the first roller 5 and the second roller 9 can fit more closely to the patient's legs to ensure the massage effect on the legs. The first roller 5 and the second roller 9 are both fixedly installed with electric heating wires. During the massage care, the electric heating wires are energized, and the electric heating wires make the first roller 5 and the second roller 9 heat up, so that the legs can be heated while massaging to enhance the massage effect.

[0044] A torsion spring is installed between the rotating rod 7 and the device slot 6, and the torsion spring can make the lower end of the swing rod 8 always press against the outer wall of the slide plate 12. That is, the structural design of the torsion spring in this embodiment is to make the swing rod always press against the slide plate.

[0045] In order to achieve the technical purpose of improving the comfort of pressing the bump, the embodiment of the present application adopts the following solution, that is, the bump 10 is disc-shaped, and the edges of the bump 10 are provided with arc-shaped chamfers. The disc-shaped bump 10 can improve the comfort during massage.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
