DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-5 This application is described in further detail.

[0029] The present application discloses a leg bone recovery auxiliary device, referring to Figure 1 , including a fixed seat 1, which is used to be fixed on the bed used by the patient, and a lifting rod 2 is fixedly arranged on the fixed seat 1, the lifting rod 2 is arranged vertically and the height of the lifting rod 2 can be adjusted, and a horizontal extension rod 3 is installed at the upper end of the lifting rod 2, and the horizontal extension rod 3 can be adjusted in height as the lifting rod 2 is adjusted. One end of the horizontal extension rod 3 is connected to the lifting rod 2, and the other end extends horizontally and is fixedly provided with a placement seat 4, which is used to support the patient's legs. The horizontal extension rod 3 is rotatably connected to the connection between the horizontal extension rod 3 and the lifting rod 2, and the rotation axis is horizontally arranged. The placement seat 4 can adjust the inclination angle with the ground during the rotation of the horizontal extension rod 3, so that the angle of the placement seat 4 can adapt to different users, and thus can support the patient's legs.

[0030] The fixing seat 1 includes a U-shaped buckle 11 and a fixing rod 12. The U-shaped buckle 11 is U-shaped as a whole and the U-shaped opening is arranged horizontally. The lower part of the U-shaped buckle 11 is connected to the fixing rod 12. The fixing rod 12 is arranged vertically and passes through the side wall of the lower part of the U-shaped buckle 11 and is threadedly connected to the U-shaped buckle 11. In this embodiment, one fixing rod 12 is provided, and two fixing rods 12 can also be provided to improve the firmness of the fixation. When in use, the opening of the U-shaped buckle 11 is clamped on the side of the bed from the side where the patient uses the bed, and then the upper end of the fixing rod 12 is abutted against the lower surface of the bed, so that the fixing seat 1 can be fixed to one side of the bed. Since the fixing seat 1 can be arranged at any position along the length of the bed, it can accommodate patients of different heights.

[0031] refer to Figure 2The lower end of the upper sleeve rod 21 is sleeved on the middle screw 23 and is threadedly connected to the middle screw 23. The upper end of the lower sleeve rod 22 is sleeved on the lower end of the middle screw 23 and is threadedly connected to the middle screw 23. The upper end of the lower sleeve rod 22 is sleeved on the lower end of the middle screw 23 and is threadedly connected to the middle screw 23. The lower sleeve rod 22 is fixed to the surface of the upper side wall of the U-shaped buckle 11 away from one end of the middle screw 23, so that the lifting rod 2 can be fixed on the fixing seat 1. At the same time, the threads at both ends of the middle screw 23 are rotated in opposite directions. When the middle screw 23 is rotated, the upper sleeve rod 21 and the lower sleeve rod 22 are simultaneously moved closer to or away from the middle of the middle screw 23, thereby adjusting the height of the lifting rod 2. A knob 24 is provided in the middle of the middle screw 23 to facilitate the staff to rotate the middle screw 23. In order to secure the upper and lower rods 21 and 22 to each other after adjustment, vertical positioning slots 25 are provided on the side walls of the intermediate screw rod 23. The positioning slots 25 are arranged along the length of the intermediate screw rod 23. Positioning screws 26 are threadedly connected to the side walls of the upper and lower rods 21 and 22. The positioning screws 26 are located near the middle of the intermediate screw rod 23 on the upper and lower rods 21 and 22, respectively. The positioning screws 26 pass through the side walls of the upper and lower rods 21 and 22, and the ends of the positioning screws 26 are inserted into the positioning slots 25. When the height of the lifting rod 2 needs to be adjusted, the positioning screws 26 are first unscrewed from the positioning slots 25, and then the intermediate screw rod 23 is rotated until the positioning slots 25 and the positioning screws 26 are aligned. The positioning screws 26 are then rotated into the positioning slots 25, thereby preventing the intermediate screw 23 from rotating relative to the upper and lower rods 21 and 22.

[0032] refer to Figure 3 The cam 52 is pressed against the bottom surface of the support 4 so that the support 4 can be fixed on the support 4 by the elastic sheet 52. The cam 52 is pressed against the bottom surface of the support 4 so that the support 4 can be fixed on the support 4 by the elastic sheet 52. The cam 52 is pressed against the bottom surface of the support 4 so that the support 4 can be fixed on the support 4 by the elastic sheet 52.

[0033] refer to Figure 4The upper end of the lifting rod 2 is rotatably installed on the worm gear 61, and the axis of the worm gear 61 is set perpendicular to the lifting rod 2. The worm gear 61 is rotatably connected to the upper end of the upper sleeve rod 21, and a connecting hole 611 is opened in the middle of the worm gear 61. The connecting hole 611 can be set into a polygon. In this embodiment, it is a regular quadrilateral. The end of the horizontal extension rod 3 connected to the lifting rod 2 is also set into a square, so that the horizontal extension rod 3 can be inserted into the connecting hole 611 and rotate with the worm gear 61, so that the placement seat 4 on the horizontal extension rod 3 can adjust the angle. At the same time, a worm 62 is vertically provided at the upper end of the lifting rod 2, and the worm 62 is rotatably connected to the upper sleeve rod 21, and the worm 62 is engaged with the worm wheel 61. The upper end of the worm 62 passes through the interior of the upper sleeve rod 21, which is convenient for operating the worm 62. When the worm 62 rotates, the worm wheel 61 can be rotated. A handwheel 621 is also fixedly provided on the upper end of the worm 62, which is convenient for rotating the worm 62 by the handwheel 621. At the same time, due to the self-locking between the worm wheel 61 and the worm 62, the adjusted horizontal extension rod 3 will not rotate automatically, thereby being able to support the patient's legs well.

[0034] refer to Figure 5 In order to facilitate the disassembly of the horizontal extension rod 3 from the lifting rod 2, the horizontal extension rod 3 can reduce the space occupied by the entire device after being disassembled from the lifting rod 2, which is convenient for storage. A plurality of steel balls 7 are provided on the side wall of one end of the horizontal extension rod 3. In this embodiment, four steel balls 7 are evenly arranged on the peripheral wall of the horizontal extension rod 3 so that the horizontal extension rod 3 can be more conveniently inserted into the connecting hole 611. At the same time, a positioning hole 63 connected to the steel ball 7 is opened on the inner wall of the connecting hole 611, and the positioning hole 63 is smaller than the hemispherical shape. A receiving hole 31 for accommodating the steel ball 7 is provided on the side wall of the horizontal extension rod 3, and a center hole 32 is provided at the center of the horizontal extension rod 3. The center hole 32 is communicated with the accommodating hole 31 and is arranged perpendicular to each other. A blocking rod 8 is provided in the center hole 32. The blocking rod 8 includes a blocking portion 81 and a releasing portion 82. The diameter of the blocking portion 81 is larger than the diameter of the releasing portion 82. A spring 9 is provided in the center hole 32. One end of the spring 9 is used to abut against the blocking rod 8, and the other end abuts against the bottom of the center hole 32. The force of the spring 9 is used to drive the blocking portion 81 to the position of the accommodating hole 31. At the same time, one end of the blocking rod 8 extends from the center hole 32, which makes it convenient for the staff to squeeze the blocking rod 8 to compress the spring 9, and then the releasing portion 82 reaches the position of the accommodating hole 31, and the steel ball 7 is moved out of the positioning hole 63 so that the horizontal extension rod 3 can be removed.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
