Referring to fig. 1-4, a limb-assist traction device includes: the device comprises a portal frame 1 and traction mechanisms, wherein the two traction mechanisms are arranged at the top end of the portal frame 1; wherein, the drive mechanism includes: the stepping motors 5 are respectively sleeved with belt wheels 6 at the same ends of the two stepping motors 5, a traction rope 9 is wound on each belt wheel 6, and the tail end of each traction rope 9 is fixedly connected with a lantern ring 4; the controller 10 is installed on the door-shaped frame 1, and the controller 10 is electrically connected with the two stepping motors 5 to control the traction ropes 9 to pull the two lantern rings 4 to stop or lift.
Through the implementation of above-mentioned technical scheme, this supplementary draw gear of limbs can drive upper limbs or low limbs placed in the lantern ring 4 through step motor 5's rotation and do up-and-down motion, and then reach the purpose of traction treatment or exercise, compare in the traditional mode of directly installing draw gear in the top of nursing bed, the utility model discloses can install door type frame 1 in the bedside, it is more convenient to use, and the security is higher.
In this embodiment, in order to adjust the transverse position of the traction mechanism to adapt to more people, the upper end of the stepping motor 5 is fixedly connected with a connecting frame 7, and a sliding hole capable of sliding at the top end of the gantry 1 is formed on the connecting frame 7.
In this embodiment, in order to reduce the weight of the connecting rack 7 and save consumables, both sides of the connecting rack 7 are hollowed out.
In this embodiment, in order to lock the position of the traction mechanism, a through hole is provided at the top of the connecting frame 7, a plurality of threaded holes 15 are arranged at the top side of the door frame 1, and a positioning bolt 8 is threaded into one of the threaded holes 15 after passing through the through hole to fix the connecting frame 7 to the door frame 1.
In this embodiment, the collar 4 is a ring-shaped structure made of cotton cloth in order to increase the comfort of the limb during traction.
In this embodiment, in order to further facilitate the installation of the door frame 1 beside the bed, the two ends of the door frame 1 are fixedly connected with connecting seats 2, and the connecting seats 2 are provided with connecting holes 3. The bed is connected with the connecting seat 2 through a plurality of bolts.
In this embodiment, in order to further increase the comfort of traction, the stepping motor 5 is a dual-shaft stepping motor, and the pulleys 6 are sleeved at both ends, the traction rope 9 is wound on each pulley, and the lantern ring 4 is connected to the lower end of each traction rope 9. All around having rolled up haulage rope 9 on four band pulleys 6, two lantern rings 4 coaxial settings on the same drive mechanism, lantern ring 4 on two adjacent drive mechanism sets up side by side, and four lantern rings 4 highly the same, can increase the traction area of contact who is pull the limbs, improves the travelling comfort.
In this embodiment, in order to prevent the stepping motor 5 from being rotated by traction when the stepping motor 5 is stopped, an electric cylinder 11 electrically connected to the controller 10 is provided at an end of the stepping motor 5, a shaft body 12 of the electric cylinder 11 extends vertically toward a rotation shaft of the stepping motor 5, and a brake pad 13 engaged with the rotation shaft is provided at an end of the shaft body 12. Through such setting, constitute braking system, when step motor 5 stopped, the axis body 12 of electronic jar 11 of controller 10 control drove brake block 13 and stretches out and press the effect of playing the brake at the pivot side of step motor 5.
