[0028] Two symmetrically distributed annular limiting rings 8 are fixedly connected to one side of the outer wall of the take-up roller 2. The inner side wall of the limiting ring 8 is provided with a rubber pad. The limiting ring 8 limits the support belt 4 to avoid direct contact between the support belt 4 and the inner wall of the fixed frame 1, thus preventing excessive friction and wear.
[0029] A rectangular positioning groove 5 is provided on one side of the fixing frame 1, and a rectangular positioning plate 6 is installed in the positioning groove 5;
[0030] The fixed frame 1 is provided with a positioning component, which includes a limiting groove 9 opened in the inner side wall of the positioning groove 5. A threaded hole 10 connected to the limiting groove 9 is opened on one side of the fixed frame 1. A first bolt 11 is installed in the threaded hole 10. One end of the bolt extends out of the threaded hole 10 and is rotatably connected to the positioning frame 12.
[0031] The positioning component is used to move and position the positioning plate 6. It is formed by the cooperation of the limiting groove 9, the threaded hole 10, the threaded hole 10, the bolt and the positioning frame 12.
[0032] An auxiliary block 13 is fixedly connected to the side of the positioning frame 12 away from the bolt. The inner wall of the positioning groove 5 is provided with a wear-resistant layer. The auxiliary block 13 facilitates the movement and positioning of the positioning plate 6.
[0033] The fixed frame 1 is provided with a winding mechanism 7. The winding mechanism 7 includes two symmetrically distributed rectangular drive grooves 73 on one side of the fixed frame 1. A cylindrical drive rod 71 is rotatably connected to the inner wall of the drive groove 73. The outer wall of the drive rod 71 is provided with anti-slip texture to improve friction and prevent slippage when rotating the drive rod 71. A worm gear 72 is fixedly connected to the outer wall of the drive rod 71.
[0034] The inner wall of the fixing frame 1 is rotatably connected to a cylindrical positioning rod 74 via a circular transmission ring. A fitting block 22 is fixedly connected to one side of the outer wall of the mounting rod 3. Two fitting blocks 22 are provided, and the two fitting blocks 22 are symmetrically distributed in a ring on the outside of the mounting rod 3.
[0035] A cylindrical positioning rod 74 is fixedly connected to a transmission rod 75 on one side near the transmission ring. The inner wall of the fixing frame 1 is provided with a through hole that communicates with the positioning groove 5. The other end of the transmission rod 75 passes through the through hole and is fixedly connected to a worm gear 76. The worm gear 76 meshes with the worm 72.
[0036] During operation, the winding mechanism 7 can be used in conjunction with the winding roller 2 and the support belt 4 to easily adjust the height of the patient's legs when supporting them, thus avoiding secondary injury to the patient.
[0037] Based on the above structure, this utility model includes the following structure:
[0038] Firstly, the mounting rod 3 and the fixing frame 1 can be fixed directly by inserting the mounting rod 3 into the insertion tube welded to the side of the orthopedic bed. If the insertion tube is not installed at the side of the bed, the frame formed by the limiting frame 14 and the limiting block 15 can be inserted into the frame on both sides of the bed to support and position the mounting rod 3.
[0039] Then one of the two drive rods 71 can be manually rotated. Drive rod 71 drives worm gear 72 to rotate. Worm gear 72 drives positioning rod 74 to rotate through worm wheel 76. Positioning rod 74 drives take-up roller 2 to rotate through interlocking block 22, and lowers the take-up support belt 4 until the support belt 4 is lowered to a suitable height, which is convenient for the patient to place their legs. The patient's legs are placed on the support belt 4 to form a U-shaped belt.
[0040] Manually reverse drive rod 71 to retract the lowered support belt 4 onto take-up roller 2, so as to simultaneously raise the low point of the U-shaped belt formed by support belt 4, thereby raising the patient's leg to a suitable height. Then stop rotating drive rod 71, and worm gear 76 and worm 72 cooperate to lock the rotation of take-up roller 2.
[0041] At the same time, given the special nature of orthopedics, the hospital bed will not be affected by excessive external forces, so there is no need to consider the possibility that the drive rod 71 may easily rotate due to external impact.
[0042] When it is necessary to lower the patient's legs, the drive lever 71 can be rotated forward again to lower the support belt 4 until it is lowered to a suitable height, and the patient can be assisted to remove the legs from the support belt 4.
[0043] When the support belt 4 is contaminated or needs to be replaced and cleaned regularly, first turn the drive rod 71 forward to lower the patient's legs, and then turn the drive rod 71 in reverse to completely retract the support belt 4 onto the take-up roller 2.
[0044] The rotatable bolt drives the positioning frame 12 to move, and the positioning frame 12 retracts into the limiting groove 9, releasing the movement positioning of the positioning plate 6. Pushing the positioning plate 6 will remove the positioning plate 6 from the positioning groove 5, and the two take-up rollers 2 that have not yet lowered the support belt 4 can be pulled out and cleaned and replaced.
[0045] The two new or cleaned take-up rollers 2 and the support belt 4 wound on the take-up rollers 2 are sequentially put back onto the positioning rod 74 from the positioning groove 5. It should be noted that the fitting block 22 should be embedded into the fitting groove 21 to ensure that the positioning rod 74 can drive the take-up roller 2 to rotate through the fitting block 22.
[0046] Place the positioning plate 6 back into the positioning slot 5. The positioning plate 6 is moved and limited by the auxiliary block 13. At the same time, reverse the bolt. The bolt drives the positioning frame 12 to reset and make the two ends of the positioning plate 6 embedded in the two positioning frames 12 respectively. The positioning plate 6 is moved and limited by the two positioning frames 12. The patient can be lifted again according to the above lifting steps.
[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
