DETAILED DESCRIPTION

[0025] In order to better explain the present invention and facilitate understanding, the preferred embodiments of the present invention are described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0026] Embodiment adjustable traction frame

[0027] like Figure 2 , Figure 3 As shown, this embodiment includes a cross bar 1, a pulley support frame 7 arranged in the middle of the cross bar 1, a first telescopic hanging rod 2 and a second telescopic hanging rod 3 respectively hinged at both ends of the cross bar 1, and a U-shaped hanging rack 24 respectively arranged at the ends of the first telescopic hanging rod 2 and the second telescopic hanging rod 3.

[0028] The first telescopic hanging rod 2 includes a first rod body 21 and a second rod body 22 sleeved with the first rod body 21. The first rod body 21 is evenly provided with five first connecting holes 211 of the same shape and size along the length direction. The second rod body 22 is provided with a second connecting hole of the same shape and size as the first connecting hole 211. The first connecting hole 211 and the second connecting hole are detachably connected through a positioning structure. The positioning structure in this embodiment adopts a bolt 23 and a nut matched with the bolt 23. The structure of the second telescopic hanging rod 3 is the same as that of the first telescopic hanging rod 2.

[0029] Specifically, the cross bar 1 of the present embodiment is a flat rod-shaped structure, which can better fit with the footboard 9 when in use. The bottom end of the second rod body 22 in the first telescopic hanging rod 2 is hinged to one end of the cross bar 1 through a first adjusting nut 5, and the bottom end of the second telescopic hanging rod 3 is hinged to the other end of the cross bar 1 through a second adjusting nut 6. The angles between the first telescopic hanging rod 2 and the second telescopic hanging rod 3 and the cross bar 1 can be adjusted respectively by the first adjusting nut 5 and the second adjusting nut 6. The top ends of the first telescopic hanging rod 2 and the second telescopic hanging rod 3 are integrally provided with a U-shaped bracket 24 for hanging on the footboard 9. When the present embodiment is in use, the U-shaped bracket 24 is inverted to form an inverted U shape.

[0030] In the present embodiment, each U-shaped hanger 24 is provided with a clamping device 4, which includes a clamping nut 41 and a clamping baffle 42 connected to the clamping nut 41. The clamping baffle 42 is vertically arranged inside the hanging space of the U-shaped hanger 24 and is parallel to the inner wall of the U-shaped hanger 24. A rubber anti-slip layer is provided on the side of the clamping baffle 42 that contacts the footboard 9.

[0031] The pulley support frame 7 includes a support rod 71 and an adjusting rod 72 arranged from bottom to top. One end of the support rod 71 is fixedly connected to the cross bar 1, and the other end is connected to one end of the adjusting rod 72 through a third adjusting nut 73. The other end of the adjusting rod 72 is connected to the pulley block 8 through a fourth adjusting nut 74.

[0032] Working principle of this embodiment:

[0033] When using this embodiment, it is necessary to make adaptive adjustments according to the actual hanging position. By changing the first connecting hole 211 that coincides with the second connecting hole, the length of the first telescopic hanging rod 2 or the second telescopic hanging rod 3 can be adjusted; the first adjusting nut 5 and the second adjusting nut 6 can be used to adjust the angles between the first telescopic hanging rod and the second telescopic hanging rod 3 and the cross bar 1 respectively. After the above adjustment, the cross bar 1 is in a horizontal state relative to the length direction of the foot board 9. By tightening the clamping nut 41, the clamping baffle 42 is tightly fitted with the foot board 9, and the present embodiment is further fixed on the foot board 9.

[0034] The third adjusting nut 73 and the fourth adjusting nut 74 are adjusted to adjust the angle between the pulley block 8 and the horizontal plane until the traction force and traction posture required by the patient are met, and finally the traction rope is wound around the pulley block to traction the patient.
