[0002] In existing medical facilities, for patients whose limbs cannot move freely, if the limbs maintain a single position for a long time, it will cause blood circulation blockage and result in swelling and pain in the patient's limbs. Therefore, a raising frame is used to elevate the affected limb, which is beneficial to blood circulation.

[0003] However, the device has the following defects when in use: Most of the current raising frames are too wide. After the patient's affected limb is placed in it, it is still not easy to fix and is prone to shaking, especially for some children with poor self-control and thinner affected limbs. Therefore, the fixing effect of the traditional raising frame is not good. For this reason, we propose a fixing device for a raising frame. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that: Most of the current raising frames are too wide. After the patient's affected limb is placed in it, it is still not easy to fix and is prone to shaking.

Detailed implementation mode

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0025] Embodiment 1:

[0026] Refer to Figures 1-5 , a lifting frame fixing device, including a bottom plate 1 and an inclined plate 2, and the bottom plate 1 and the inclined plate 2 are connected through a hinge part 3.

[0027] The hinge part 3 includes two first fixed sleeves 31 fixedly connected to one side of the bottom plate 1. A fixed rod 32 is arranged on one side of the bottom plate 1, and the fixed rod 32 fixedly passes through the two first fixed sleeves 31. A second fixed sleeve 33 is fixedly connected to one side of the inclined plate 2, and the second fixed sleeve 33 is rotatably connected to the fixed rod 32. In the initial state, the top surface of the bottom plate 1 and the bottom surface of the inclined plate 2 are in contact (as Figure 1 shown). When the device needs to be used, the inclined plate 2 rotates relative to the bottom plate 1, the inclined plate 2 drives the second fixed sleeve 33 to move, and the second fixed sleeve 33 rotates relative to the fixed rod 32.

[0028] An adjusting part 34 is arranged inside the bottom plate 1. The adjusting part 34 includes a cavity 35 opened inside the bottom plate 1. A sliding bar 36 is slidably connected inside the cavity 35. A screw rod 37 is horizontally rotatably connected inside the cavity 35. The screw rod 37 is in threaded connection with the sliding bar 36, and a part of the screw rod 37 extends outside the bottom plate 1. A plurality of avoiding channels 38 are opened at the top of the bottom plate 1. A plurality of connecting rods 39 are hinged to the side wall of the sliding bar 36. The connecting rods 39 pass through the corresponding avoiding channels 38, and the tops of the connecting rods 39 are hinged to the bottom surface of the inclined plate 2.

[0029] In the initial state, the connecting rods 39 are completely located inside the corresponding avoiding channels 38 and the cavity 35, and the bottom plate 1 and the inclined plate 2 are in contact with each other. When the device needs to be used, the staff rotates the screw rod 37 to drive the sliding bar 36 to move horizontally. The sliding bar 36 drives a plurality of connecting rods 39 to move. The connecting rods 39 drive the inclined plate 2 to rotate, and the inclined plate 2 drives the second fixing sleeve 33 to rotate.

[0030] One side of the second fixing sleeve 33 is fixedly connected with an indicating rod 12. The indicating rod 12 is arranged in an L shape. One end of the fixing rod 32 is fixedly connected with a scale disk 13. In the initial state, the indicating rod 12 points to the 0 scale on the scale disk 13. When the inclined plate 2 rotates, the second fixing sleeve 33 rotates synchronously. The second fixing sleeve 33 drives the indicating rod 12 to rotate, and the position where the indicating rod 12 points on the scale disk 13 changes. Therefore, by observing the scale on the scale disk 13 pointed by the indicating rod 12, the rotation angle of the inclined plate 2 can be directly known, which is convenient for the staff to accurately adjust the angle of the inclined plate 2.

[0031] Four top grooves 4 are opened at the top of the inclined plate 2. A lead screw 5 is jointly rotatably connected inside the corresponding two top grooves 4. The thread helix directions of the outer peripheral surfaces of the parts of the lead screw 5 located inside the two top grooves 4 are opposite. A screw plate 6 is in threaded connection with the outer peripheral surface of the lead screw 5 at the part located inside the top groove 4. The screw plate 6 is slidably connected with the corresponding top groove 4. Two motors 7 are fixedly connected to one side of the inclined plate 2. The output ends of the motors 7 are in transmission connection with the lead screw 5.

[0032] The upper half of the screw plate 6 extends above the inclined plate 2. When the motor 7 works, it drives the lead screw 5 to rotate. The rotation of the lead screw 5 drives the two screw plates 6 to move in opposite directions, so as to adjust the distance between the two screw plates 6 to adapt to the affected limbs of different widths and improve the fixing effect on the affected limbs.

[0033] Flexible cushion blocks 11 are fixedly connected to the mutually approaching sides of the two screw plates 6. The flexible cushion blocks 11 are located below the elastic band 9. The movement of the screw plates 6 enables the two flexible cushion blocks 11 to contact the affected limbs. The flexible cushion blocks 11 are made of sponge material, which can avoid hurting the affected limbs and make the affected limbs more comfortable.

[0034] An escape opening 8 is provided on the upper half of one side of the screw plate 6, and an elastic band 9 is passed through the two escape openings 8. A collecting portion 10 is provided on one side of the screw plate 6. The collecting portion 10 includes two side plates 101 fixedly connected to the side wall of the screw plate 6, and a rotating rod 102 is rotatably connected between the two side plates 101. The elastic band 9 is fixedly wound around the outer circumference of the two rotating rods 102 near both ends, and two connecting ropes 103 are fixedly connected to the inner side wall of the top groove 4. The portion of the connecting rope 103 away from the inner side wall of the top groove 4 is fixedly wound around the outer circumference of the corresponding rotating rod 102.

[0035] In the initial state, the distance between the two screw plates 6 is large, and the length of the elastic band 9 outside the rotating rod 102 is large. When the affected limb is placed, it passes through the area surrounded by the corresponding two screw plates 6, the elastic band 9 and the top surface of the inclined plate 2, and then the motor 7 works to drive the two screw plates 6 to approach each other. At the same time, the connecting rope 103 pulls the rotating rod 102 to rotate, so that the elastic band 9 is collected to the outer peripheral side of the rotating rod 102 until the two flexible pads 11 both contact the affected limb, and the elastic band 9 is in a taut state. The elastic band 9 restricts the upper part of the affected limb, so that the affected limb cannot move upward and escape from between the two flexible pads 11.

[0036] When the fixation of the affected limb needs to be released, the motor 7 works in the reverse direction, the two screw plates 6 move back to back, the elastic belt 9 pulls the rotating rod 102 to rotate, the elastic belt 9 is released, and the rotating rod 102 rotates so that the connecting rope 103 is collected to the outer peripheral side of the rotating rod 102, thereby restoring the elastic belt 9 and the connecting rope 103 to their initial state, and then the screw rod 37 is rotated to restore the inclined plate 2 to a horizontal state, and finally the device is removed.

[0037] Embodiment 2:

[0038] Reference Figure 6 A bottom shell with an opening at the top is provided below the bottom plate 1, a slide plate is slidably connected in the bottom shell, a screw rod is rotatably connected to the bottom wall of the bottom shell, the screw rod and the slide plate are slidably connected, a driving rod is rotatably penetrated on one side of the bottom shell, the driving rod is connected to the screw rod through a bevel gear set, two top blocks are fixedly connected to the top of the slide plate, and the top of the top block is fixedly connected to the bottom surface of the bottom plate 1.

[0039] When the height of the base plate 1 needs to be adjusted, the staff rotates the driving rod, and the driving rod drives the screw to rotate through the bevel gear set, the screw drives the slide plate to move vertically, and the slide plate drives the top block to move vertically, thereby driving the base plate 1 to move vertically and adjust the height of the base plate 1 to adapt to different usage scenarios.
