[0028] See also Figures 1 to 5 The utility model provides a technical solution: a lifting orthopedic reduction device, including a plurality of equally spaced lifting support components, the lifting support components including a bottom driving mechanism and a top supporting mechanism, the driving mechanism and the supporting mechanism are connected by a double-layer X frame; the driving mechanism includes a bottom slide rail 8, one end of the bottom slide rail 8 is connected to a positioning cover 15, and the other end is equipped with a supporting seat 9, a ball screw 6 is rotatably connected between the positioning cover 15 and the supporting seat 9, one end of the ball screw 6 passes through the supporting seat 9 and is connected to a locking component, a slider 7 is threadedly sleeved on the ball screw 6, and guide slide rails are fixed on both sides of the length direction of the bottom slide rail 8, Guide balls adapted to the guide rails are respectively arranged on both sides of the slider 7. A servo motor 17 for driving the ball screw 6 is fixedly installed at one end of the positioning cover 15. The servo motor 17 is a servo motor with a brake and has good stability. When working, the servo motor 17 is started to drive the ball screw 6 to rotate, so that the slider 7 moves in the guide of the bottom rail 8, and the guide balls on the slider 7 move in the guide rail on the bottom rail 8. The support mechanism includes a support shell 2, and a soft pad 3 is fixed on the top of the support shell 2. The soft pad 3 includes a sponge lining and an external leather skin. The double-layer X frame includes two groups of brackets, and the two groups of brackets are rotatably connected by a pin shaft, such as Figure 1 and Figure 4 As shown, a set of brackets consists of two.

[0029] like Figure 4 As shown, the locking assembly includes a locking block 10, which is provided with a slot hole for inserting the end of the ball screw 6, and an adjusting slot 101 connected to the slot hole is provided on the locking block 10 on one radial side of the slot hole. A fastening pin 11 for adjusting the width of the adjusting slot 101 is threadedly installed on the locking block 10, and the locking block 10 is fixedly connected to the support seat 9. The bottom end of the fastening pin 11 is rotatably connected to the locking block 10 below the adjusting slot 101, and a threaded hole adapted to the fastening pin 11 is provided on the locking block 10 above the adjusting slot 101. When working, the fastening pin 11 is rotated clockwise or counterclockwise to shorten the width of the adjusting slot 101, thereby making the inner wall of the slot hole tightly press against the ball screw 6, and the ball screw 6 is clamped and cannot rotate, with good stability.

[0030] like Figure 1 and Figure 5 As shown, a through hole is opened in the middle of the bracket for the pin to pass through, and an oil-free bushing 13 is sleeved on the pin inside the through hole. Both ends of the oil-free bushing 13 extend to the outside of the bracket respectively, and locking nuts are installed at the ends of the pin outside the bracket. By fixing the oil-free bushing 13 on the outside of the pin and installing the locking nut on the end of the pin, the clearance at the hinge is reduced, the shaking is reduced, and the stability of the double-layer X-frame hinge is enhanced.

[0031] like Figure 1 and Figure 2 As shown, it also includes a limit switch, which includes a slot-type photoelectric switch 12 and a baffle 701. The top of the baffle 701 is bent to one side and fixedly connected to the slider 7. The outer cover of the driving mechanism is provided with a protective shell 1. The side of the protective shell 1 is provided with a through slot for the baffle 701 to pass through. The slot-type photoelectric switch 12 is installed on the protective shell 1 at the bottom wall of the through slot. The entire driving mechanism including the servo motor 17 is located inside the protective shell 1. Two slot-type photoelectric switches 12 are provided, which are respectively located at both ends of the baffle 701. When the slider 7 is guided to move and drive the baffle 701 to move into the slot-type photoelectric switch 12, the baffle 701 will block the light beam inside the slot-type photoelectric switch 12. At this time, the receiver will receive a signal, thereby triggering the state change of the servo motor 17.

[0032] like Figure 1 and Figure 2 As shown, a second cushion block 16 is detachably mounted on the top of the positioning cover 15, and a first cushion block 14 is detachably mounted on the top of the slider 7. The second cushion block 16 is connected to the positioning cover 15 via bolts, and the first cushion block 14 is connected to the slider 7 via bolts.

[0033] like Figure 5 As shown, an upper slide rail 18 is detachably installed at one end of the bottom of the supporting shell 2, and an anti-slip slide rail 4 is fixed to the end of the supporting shell 2 away from the upper slide rail 18. An anti-slip slider 5 is guided and installed on the anti-slip slide rail 4. When the double-layer X-frame is extended or contracted, the anti-slip slider 5 will be driven to move on the anti-slip slide rail 4.

[0034] like Figure 1 and Figure 5 As shown, one end of one group of brackets is hinged with a cushion block 2 16 and the other end is hinged with an anti-dropping slider 5, and the remaining group of brackets is hinged with a cushion block 14 at one end and an upper slide rail 18 at the other end.

[0035] In this device, one lifting support component corresponds to one switch, which can be flexibly adjusted according to the spinal curvature of different patients to improve the comfort of the patients.

[0036] During operation, the personnel starts the switch and the servo motor 17 starts, driving the ball screw 6 to rotate, so that the slider 7 moves along the bottom slide rail 8, and the baffle 701 moves accordingly. When the slider 7 moves, it drives the double-layer X-frame to extend or fold, thereby driving the cushion 3 to rise and fall. When the baffle 701 enters the slot-type photoelectric switch 12, the baffle 701 will block the light beam inside the slot-type photoelectric switch 12. At this time, the servo motor 17 is turned off, the ball screw 6 no longer rotates, and the cushion 3 will be fixed in the current position. In order to further improve the stability of the support of the cushion 3, a mechanical fixing mechanism is added to the device, that is, the locking block 10 is fixedly connected to the outer end of the support seat 9 by bolts, and one end of the ball screw 6 passes through the support seat 9 and is inserted into the locking block 10. By manually rotating the fastening pin 11, the gap of the adjustment gap 101 is shortened, thereby clamping the ball screw so that it cannot rotate.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
