DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4 An embodiment of the utility model provides a hospital bed traction device, comprising: a base frame 1 and a mounting frame 3, wherein the mounting frame 3 is arranged above the base frame 1.

[0020] Four connecting rods 2 are fixedly connected to the base frame 1, and the four corners of the mounting frame 3 are slidably connected to the four connecting rods 2, and the external threads of the connecting rods 2 are connected to the positioning bolts 20, which are located below the mounting frame 3. The external part of the base frame 1 is fixedly connected to the bottom plate 4, and the external part of the bottom plate 4 is hinged with two sleeves 5. The external part of the mounting frame 3 is hinged with two telescopic rods 7, and the two telescopic rods 7 are respectively slidably connected to the inside of the sleeves 5. The external part of the mounting frame 3 is fixedly connected to two groups of vertical plates 9, and the number of each group of vertical plates 9 is two. The internal part of each vertical plate 9 is threadedly connected to a threaded rod 13, and the ends of the threaded rod 13 are rotatably connected to a soft splint 11, and the two soft splints 11 are arranged opposite to each other. A traction mechanism is installed on the external part of the mounting frame 3. The external part of the mounting frame 3 is sleeved with a first cloth body 6, and the external part of the two sleeves 5 is sleeved with a second cloth body 8.

[0021] The traction mechanism includes a first bracket 14 and a second bracket 18. The first bracket 14 and the second bracket 18 are both fixedly connected to the outside of the base frame 1 and are equipped with a roller 17. The outside of the roller 17 is rollingly connected with a traction rope 16. One end of the traction rope 16 is fixedly connected to the traction hook 12, and the other end of the traction rope 16 is fixedly connected to the counterweight plate 15.

[0022] When in use, the patient places the thigh on the second cloth body 8, and then places the calf on the first cloth body 6, uses the traction mechanism to perform traction, and places a weight block on the weight plate 15 to complete the leg traction. The two sets of threaded rods 13 on both sides are rotated to push the soft splint 11 to clamp the calf, fix the calf and foot, and limit the patient's foot shaking to cause pain.

[0023] In addition, when it is necessary to adjust the angle of the overall leg lifting to make the patient more comfortable to place the legs for a long time, the height of the mounting frame 3 and the first cloth body 6 can be raised or lowered by adjusting the height of the positioning bolt 20, and at the same time, the mounting frame 3 drives the telescopic rod 7 to change the angle, and the telescopic rod 7 drives the sleeve 5 and the second cloth body 8 to change the angle, so as to achieve the purpose of adjusting the support angle and height. It should be noted that the telescopic rod 7 slides in the sleeve 5, and the telescopic rod 7 is hingedly mounted on the mounting frame 3, and the sleeve 5 is hingedly mounted on the bottom plate 4, so when the mounting frame 3 is raised or lowered, the length and angle formed by the sleeve 5 and the telescopic rod 7 can be changed, and the sleeve 5 is fixedly connected to the inside of the spring 19, which can push the telescopic rod 7 outward when the mounting frame 3 is adjusted.

[0024] Among them, in order to stabilize the soft splint 11, two limit rods 10 are fixedly connected to the outside of the soft splint 11, and the limit rods 10 are slidably connected to the inside of the vertical plate 9; in order to prevent the mounting frame 3 from falling off the connecting rod 2, one end of the connecting rod 2 is fixedly connected to the limit block 21.

[0025] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when the utility model is used, the patient places the thigh on the second cloth body 8, and then places the calf on the first cloth body 6, uses the traction mechanism to implement the traction operation, and places the counterweight block on the counterweight plate 15 to complete the leg traction operation. The two sets of threaded rods 13 on both sides are rotated to push the soft splint 11 to clamp the calf, fix the calf and foot, and limit the patient's foot shaking to cause pain. When it is necessary to adjust the overall lifting angle of the leg to make the patient more comfortable to place the leg for a long time, the height of the positioning bolt 20 is adjusted to increase or decrease the height of the mounting frame 3 and the first cloth body 6, and at the same time, the mounting frame 3 drives the telescopic rod 7 to change the angle, and the telescopic rod 7 drives the sleeve 5 and the second cloth body 8 to change the angle, so as to achieve the purpose of adjusting the support angle and height.
