Detailed Implementation
[0021] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] Example 1
[0023] like Figures 1 to 6As shown, a bedside standing device with auxiliary support according to the first aspect of this utility model includes an adjustment knob 1, a drive gear 2, an eccentric gear 3, an eccentric protrusion 4, a drive linkage 5, a mounting base plate 6, an active thigh linkage 8, a knee joint connecting plate 9, a calf linkage 10, an ankle joint connecting plate 11, a foot pedal 14, a calf sleeve 17, a thigh sleeve 18, an angle locking bolt 25, and a chest sleeve 19. Mounting base plates 6 are respectively installed on both sides of the lower part of the chest sleeve 19. One end of the drive linkage 5 is hinged to the side of the mounting base plate 6, and the other end of the drive linkage 5 is hinged to one end of the active thigh linkage 8. The other end of the active thigh linkage 8 is hinged to the upper end of the knee joint connecting plate 9, and the lower end of the knee joint connecting plate 9 is hinged to one end of the calf linkage 10. An ankle joint connecting plate 11 is installed at the other end of the lower leg connecting rod 10, and a foot pedal 14 is hinged to the lower end of the ankle joint connecting plate 11; a drive gear 2 is fixed to the inner end face of the adjustment knob 1, and the drive gear 2 and the eccentric gear 3 are rotatably connected to the side of the mounting base plate 6. The outer edge of the eccentric gear 3 meshes with the drive gear 2 for transmission. An eccentric protrusion 4 is provided at the eccentric part of the eccentric gear 3. The hinge of the drive connecting rod 5 and the active thigh connecting rod 8 is connected to the eccentric protrusion 4; an angle locking bolt 25 is threaded through the mounting base plate 6 and its inner end can contact and abut against the inner end face of the adjustment knob 1 to lock the rotation of the adjustment knob 1; a thigh sleeve 18 is installed in the middle of the active thigh connecting rod 8, and a lower leg sleeve 17 is installed in the middle of the lower leg connecting rod 10.
[0024] In the above embodiment, it should be noted that mounting base plates 6 are respectively installed on the lower two sides of the chest sleeve 19, corresponding to the left and right legs of the human body. By adjusting the rotation of the knob 1, the drive gear 2 rotates, which in turn drives the eccentric gear 3 to rotate, thereby driving one end of the active thigh link 8 to rotate, thereby realizing the adjustment of the angle between the active thigh link 8 and the lower leg link 10. From the position where the two are in the same vertical plane, it can be adjusted to a certain angle between the two, thereby realizing the knee flexion operation of the patient's leg. When it is necessary to lock the knee flexion angle between the active thigh link 8 and the lower leg link 10 at a specified position, tighten the angle locking bolt 25 so that its inner end abuts against Connected to the inner end face of the adjustment knob 1, the adjustment knob 1 stops rotating due to the friction between the angle locking bolt 25 and the adjustment knob 1, and the drive gear 2 is also locked at a fixed angle, thereby locking the rotation of the eccentric gear 3. When it is necessary to readjust the knee flexion angle between the active thigh link 8 and the lower leg link 10, loosen the angle locking bolt 25 so that its inner end is not in contact with the inner end face of the adjustment knob 1. At this time, the knee flexion angle between the active thigh link 8 and the lower leg link 10 can be adjusted arbitrarily. In use, both the lower leg sleeve 17 and the thigh sleeve 18 are fixed with Velcro, thereby fixing the patient's thigh and lower leg.
[0025] The technical effects achieved by the above embodiments are as follows: the bedside standing device with auxiliary support of this device provides auxiliary support for patients with lower limb dysfunction to stand at the bedside. By adjusting the rotation of the knob and locking it with the angle locking bolt, the knee flexion and other movements can be locked at a designated position. This device effectively assists in the recovery of the patient's lower limb function, with significant recovery effect and good user experience.
