[0029] Refer to Figures 1 to 4, an embodiment of the present utility model provides a leg bracket, including: a buckle 1, a leg support 7 and a bracket. Among them, the bracket includes a first bolt 24, a second bolt 34, a first rod 2, a second rod 3 and a third rod 4. One end of the first rod 2 is provided with a first steering ball 23, and the other end of the first rod 2 is connected to the leg support 7; one end of the third rod 4 is fixed on the buckle 1, and the other end of the third rod 4 is provided with a first steering seat 5; as Figure 4 shown, one end of the second rod 3 is provided with a second steering ball 33, and the other end of the second rod 3 is provided with a second steering seat 6.
[0030] The first steering seat 5 is provided with a first groove and a first threaded hole that communicate with each other, and the second steering seat 6 is provided with a second groove 61 and a second threaded hole 62 that communicate with each other. The first steering ball 23 is placed in the second groove 61, and the first steering ball 23 and the second steering seat 6 are connected in a spherical pair. The second steering ball 33 is placed in the first groove, and the second steering ball 33 and the first steering seat 5 are connected in a spherical pair.
[0031] The first bolt 24 is threadedly connected to the first threaded hole so as to be able to extend into the first groove and press the second steering ball 33, and the second bolt 34 is threadedly connected to the second threaded hole 62 so as to be able to extend into the second groove 61 and press the first steering ball 23.
[0032] In this embodiment, the buckle 1 is used to connect the bracket and the hospital bed. The second rod 3 realizes the angle and height adjustment of the second rod 3 relative to the buckle 1 through the spherical pair structure formed between the second steering ball 33 and the first steering seat 5, thereby driving the position change of the first rod 2. Then, by extending the first bolt 24 into the first groove to press the second steering ball 33 and the inner wall of the first groove, the friction between the second steering ball 33 and the inner wall of the first groove is increased, and the position of the second rod 3 is locked. Similarly, the first rod 2 realizes the angle and height adjustment of the first rod 2 through the spherical pair structure of the first steering ball 23 and the second steering seat 6, thereby driving the position change on the leg support 7 on the first rod 2. Then, the position of the first rod 2 is locked by the second bolt 34. Through the two spherical pair structures, the position change of the leg support 7 relative to the hospital bed is finally realized. When the patient is in the lateral position, the legs can be placed on the leg support 7 with the adjusted position. The position is accurate and suitable for patients with different heights and weights.
[0033] As an example, the buckle 1 includes a buckle body and a third bolt 14. A through hole 13, a third threaded hole 12 and a chute 11 are provided on the buckle body. The chute 11 penetrates through opposite sides of the buckle body and is adapted for a slide rail on a hospital bed to pass through. The third threaded hole 12 communicates with the through hole 13. The third bolt 14 is threadedly connected to the third threaded hole 12 so as to be able to extend into the through hole 13 and press the third rod 4. In this embodiment, the buckle 1 is put on the slide rail on the hospital bed, and screws or the like can be used to lock the position of the buckle 1. Since the third bolt 14 can apply pressure to the third rod 4 after the third rod 4 penetrates into the through hole 13, the friction between the third rod 4 and the inner wall of the through hole 13 is increased, thereby locking the position of the third rod 4. Therefore, in this embodiment, the position of the leg rest 7 can also be adjusted by the length of the third rod 4 penetrating into the through hole 13.
[0034] As an example, the first rod 2 includes a first tip 21 and a first rod body 22. One end of the first tip 21 is fixed to one end of the first rod body 22, and the other end of the first tip 21 is connected to a first steering ball 23. The cross-section of the first tip 21 decreases in the direction away from the first rod body 22. The end of the first rod body 22 away from the first tip 21 is connected to the leg rest 7. In this embodiment, since the closer the first tip 21 is to the first steering ball 23, the smaller the cross-section of the first tip 21, the rotation angle of the first tip 21 can be increased, the range of the rotation angle of the first rod 2 is increased, and thus the range of adjustment of the position of the leg rest 7 is increased.
[0035] As an example, the second rod 3 includes a second tip 31 and a second rod body 32. One end of the second tip 31 is fixed to one end of the second rod body 32, and the other end of the second tip 31 is connected to a second steering ball 33. The cross-section of the first tip 21 decreases in the direction away from the second rod body 32. The second steering seat 6 is provided at the end of the second rod body 32 away from the first tip 21. Similarly to the first tip 21, it will not be elaborated here.
[0036] As an example, the leg rest 7 includes a bracket 71, a first connecting band 72 and a second connecting band 73. An arc-shaped groove 74 for placing the leg is provided on the upper surface of the bracket 71. The lower surface of the bracket 71 is connected to the first rod 2; one end of the first connecting band 72 is fixed to the bracket 71, one end of the second connecting band 73 is fixed to the bracket 71, and the end of the first connecting band 72 away from the bracket 71 and the end of the second connecting band 73 away from the bracket 71 are detachably connected. The first connecting band 72 and the second connecting band 73 are connected together for binding the leg located in the arc-shaped groove 74. A plurality of first connecting bands 72 and second connecting bands 73 can be provided, and each first connecting band 72 and each second connecting band 73 form a group. Multiple groups are arranged along the length direction of the arc-shaped groove 74.
[0037] Further, a first magic tape is fixed to one end of the first connecting belt 72 away from the bracket 71. The first magic tape extends along the length direction of the first connecting belt 72. A second magic tape is fixed to one end of the second connecting belt 73 away from the bracket 71. The second magic tape extends along the length direction of the second connecting belt 73. The first connecting belt 72 and the second connecting belt 73 are detachably connected by the first magic tape and the second magic tape. In this embodiment, the detachable connection is achieved by the magic tape, and the overall length formed after the first connecting belt 72 and the second connecting belt 73 are connected can also be adjusted by the magic tape, so as to fit the legs of patients with different thicknesses.
[0038] As an example, the leg bracket further includes a first force - adding rod 25 and a second force - adding rod 35. The first force - adding rod 25 is rotatably connected to one end of the first bolt 24 away from the first steering seat 5. The rotation axis of the first force - adding rod 25 is perpendicular to the first force - adding rod 25 and the first bolt 24. When a medical staff rotates the first bolt 24, first rotate the first force - adding rod 25 until the first force - adding rod 25 is perpendicular to the first bolt 24, and then rotate the first force - adding rod 25 around the axial direction of the first bolt 24. At this time, the first force - adding rod 25 acts as a lever to reduce the rotational force for the medical staff to rotate the first bolt 24, facilitating the rotation by the staff.
[0039] The second force - adding rod 35 is rotatably connected to one end of the second bolt 34 away from the second steering seat 6. The rotation axis of the second force - adding rod 35 is perpendicular to the second force - adding rod 35 and the second bolt 34. Similar to the first force - adding rod 25, it will not be elaborated here.
[0040] As an example, the leg bracket further includes a third force - adding rod 15. The third force - adding rod 15 is rotatably connected to one end of the third bolt 14 away from the buckle body. The rotation axis of the third force - adding rod 15 is perpendicular to the third force - adding rod 15 and the third bolt 14. Similar to the first force - adding rod 25, it will not be elaborated here.
[0041] The working process of this embodiment is as follows: First, install the buckle 1 on the hospital bed, slide the chute 11 onto the slide rail of the hospital bed, insert the third rod 4 into the through - hole 13, and adjust the inserted length. Then rotate the third bolt 14 to lock the third rod 4.
[0042] Then rotate the second rod 3 and / or the first rod 2. By adjusting the relative positions of the first rod 2 and the second rod 3, the position of the leg support 7 is adjusted. After the leg support 7 is adjusted to the appropriate position, rotate the second bolt 34 to lock the first steering ball 23, and rotate the first bolt 24 to lock the second steering ball 33.
[0043] In other embodiments, the buckle 1 includes a buckle body and a third bolt 14. The buckle body is provided with a sliding groove 11 and a third threaded hole 12. The sliding groove 11 penetrates through opposite sides of the buckle body and is adapted for a slide rail on the hospital bed to pass through. The third threaded hole 12 communicates with the sliding groove 11. The third bolt 14 is threadedly connected to the third threaded hole 12 so as to be able to extend into the sliding groove 11 and press against the slide rail on the hospital bed. The third support rod 4 is fixed to the buckle body. In this embodiment, the third support rod 4 is directly fixed to the buckle body. The buckle body is still slidably connected to the slide rail on the hospital bed through the sliding groove 11, and then the position of the buckle body relative to the hospital bed is locked by the third bolt 14. In this embodiment, only the second support rod 3 and the first support rod 2 are used to adjust the position of the leg rest 7.
[0044] In other embodiments, the buckle 1 includes a buckle body and a third bolt 14. The buckle body is provided with a second through hole 13 and a third threaded hole 12. The third threaded hole 12 communicates with the second through hole 13. The buckle body is detachably connected to the hospital bed. The third support rod 4 passes through the second through hole 13. The third bolt 14 is threadedly connected to the third threaded hole 12, and the third bolt 14 can extend into the second through hole 13 and press against the third support rod 4. In this embodiment, the buckle body can also be detachably connected to the hospital bed by means of magnets, buckles 1, bolts, etc. It can also be detachably connected by providing a clamping mechanism on the buckle body and clamping the hospital bed through the clamping mechanism.
