[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Depend on Figure 1-Figure 3 As shown, it relates to an anti-pressure sore adjustable traction frame, including a top plate 1, two rectangular sleeves 2 are fixedly connected to the bottom of the top plate 1, the inner walls of the two rectangular sleeves 2 are slidably connected with internal thread L-shaped sliding sleeves 4, and the rectangular sleeves 2 move up and down through the internal thread L-shaped sliding sleeves 4. Two through holes are opened on the top of the top plate 1, and the inner walls of the two through holes are slidably connected with screws 3. The outer walls of the two screws 3 are fixedly sleeved with bearings, and the outer rings of the two bearings are fixedly connected to the top of the top plate 1.

[0022] The outer walls of the two screws 3 are threadedly connected to the inner walls of the two internally threaded L-shaped sleeves 4. After the screw 3 rotates, the rectangular sleeve 2 and the top plate 1 rise and fall with the screw 3. The tops of the two internally threaded L-shaped sleeves 4 are provided with sliding holes. The inner walls of the two sliding holes are slidably connected to the outer walls of the two screws 3 respectively. The bottoms of the two internally threaded L-shaped sleeves 4 are fixedly connected to the base plate 5. The bottoms of the two base plates 5 are fixedly connected to two universal wheels 6. The two base plates 5 move through four universal wheels 6. At the same time, the four universal wheels 6 provide supporting force. The four universal wheels 6 are designed with existing mechanical structures, such as using springs or lever mechanisms. When external pressure is applied, the mechanical structure will contact the wheels and generate friction, thereby preventing the wheels from rotating. The tops of the two screws 3 are fixedly connected to turntables 7, and the tops of the two turntables 7 are fixedly connected to power-assisting rods 8. The power-assisting rods 8 facilitate driving the turntables 7 to rotate.

[0023] Two fixed plates 9 are fixedly connected to the bottom of the top plate 1, and two guide rods 10 are fixedly connected between the two fixed plates 9. The outer walls of the two guide rods 10 are slidingly sleeved with two rectangular movable adjustment blocks 11. The rectangular movable adjustment blocks 11 slide through the two guide rods 10. The outer walls of the two rectangular movable adjustment blocks 11 are each provided with two assembly holes, and the inner walls of the two assembly holes are rotatably inlaid with multiple ball bearings. The bottoms of the two rectangular movable adjustment blocks 11 are fixedly connected with L-shaped metal support rods 12.

[0024] A traction mechanism is provided under the top plate 1, which includes two arc-shaped support plates 14. The tops of the two L-shaped metal support rods 12 are fixedly connected with arc-shaped connecting blocks 13. The two L-shaped metal support rods 12 support the two arc-shaped support plates 14. The tops of the two arc-shaped connecting blocks 13 are fixedly connected to the bottoms of the two arc-shaped support plates 14 respectively. The outer walls of the two arc-shaped support plates 14 are fixedly connected with Velcro 15. The suede surface of Velcro 15 is installed on the outer wall of the arc-shaped support plate 14 opposite to the Velcro 15, which is bonded to the hook surface on the Velcro 15 to limit the patient's legs. At the same time, Velcro 15 can be added to the arc-shaped support plate 14. The tops of the two arc-shaped support plates 14 are fixedly connected with sponge pads 16.

[0025] Working principle: When in use, the top plate 1 is moved to the top of the bed by the four universal wheels 6 and is located above the patient. The distance between the two bottom plates 5 is greater than the width of the bed. The top plate 1 is moved to a suitable position above the patient's legs. The patient's legs are placed on the sponge pad 16 and supported by the arc-shaped support plate 14. The Velcro 15 is then tied to the arc-shaped support plate 14 to fix the patient's legs on the arc-shaped support plate 14. The two turntables 7 are rotated by the two power rods 8 to rotate the two screws 3. Since the screws 3 are threadedly connected to the internal thread L-shaped sleeve 4, the two turntables 7 are rotated. After the screw 3 rotates, the internal thread L-shaped sliding sleeve 4 is supported by the bottom plate 5, and the two rectangular sleeves 2 and the top plate 1 move up and down to adjust the height of the top plate 1 so that the two arc-shaped support plates 14 of different heights can pull the patient's legs. At the same time, the two rectangular movable adjustment blocks 11 can be moved to make the L-shaped metal support rod 12 drive the arc-shaped support plate 14 to move horizontally to adjust the horizontal position and spacing between the patient's legs. At the same time, the four universal wheels 6 and the two bottom plates 5 can also be moved to adjust the overall horizontal steering angle to facilitate traction of the patient's legs.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, numerous modifications and variations are possible based on the contents of this specification.
