Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, the utility model discloses an orthopedic traction frame, including vertical support body 1, rotate at vertical support body 1's middle part and be connected with a seat 2, the fixed cover is equipped with the cushion on seat 2's the face, and seat 2 can only rotate around vertical support body 1 on the horizontal direction. The top of the vertical supporting frame body 1 is provided with a hand traction device, and the bottom of the vertical supporting frame body 1 is provided with a leg traction device. The hand traction device comprises a first connecting frame 31, a first belt pulley 33 and two hand cranks 32. First link 31 rotates with vertical support frame body 1 to be connected, and the centre of rotation of first belt pulley 33 rotates with first link 31 to be connected, and two crank 32 rotate respectively to be connected on the relative both sides wheel face of first belt pulley 33 to two crank 32 are all inconsistent with the axis of rotation of first belt pulley 33.

The leg pulling means comprises a second connecting frame 61, a second pulley 63 and two foot supports 62. The second connecting frame 61 is rotatably connected with the vertical support frame body 1. The centre of gyration of second belt pulley 63 rotates with second link 61 to be connected, and two pedals 62 also rotate respectively to be connected on the both sides wheel face of second belt pulley 63 to two pedals 62 are inconsistent with the axis of gyration of second belt pulley 63.

In this scheme, first link 31 and second link 61 all can only use vertical support body 1 as the axis, make a round trip to rotate on the left side of the horizontal direction, and as an optimization, first belt pulley 33 and second belt pulley 63 link together through synchronous belt 5. At this time, the first connecting frame 31 and the second connecting frame 61 can rotate synchronously on the horizontal plane.

The specific implementation mode is as follows: the hand traction device and the leg traction device are rotated to the same side, and the hand traction device and the leg traction device are both rotated to the opposite side of the seat plate 2 relative to the vertical support frame 1. The patient sits on the elastic cushion, holds the two hand-operated handles 32 with both hands, and steps on the two pedals 62 with both feet. At the moment, the two upper limbs of the patient rotate the first belt pulley 33 through the hand crank 32, and the two legs of the patient rotate the second belt pulley 63 through the foot pedals 62, so that the synchronous traction of the four limbs of the patient is realized. When the four limbs do not need to be synchronously pulled, the synchronous belt 5 can be taken down, so that the upper limbs or the lower limbs of the patient can be independently rotated and pulled, the device is suitable for different application scenes, and different requirements of the patient are met. In order to prevent the timing belt 5 from slipping, a tie bar 4 is provided between the first link frame 31 and the second link frame 61, one end of the tie bar 4 is bolted to the first link frame 31, and the other end of the tie bar 4 is bolted to the second link frame 61. Under the connecting and fixing action of the pull rod 4, the first connecting frame 31 and the second connecting frame 61 can be enabled to better perform horizontal synchronous rotation, and the synchronous belt 5 can be connected with the second belt pulley 63 and the second belt pulley 63 stably.

In essence, without the pull rod 4, the patient can maintain the cooperation of the limbs through his own waist, and the synchronous belt 5 is ensured not to fall off after connecting the first belt pulley 33 and the second belt pulley 63, which is a way to increase the training, and exercise on other parts of the patient's body, such as waist strength training, can be realized. In the optimized scheme, the vertical support frame 1 is further provided with a power module 71, a display screen 74 and a variable frequency controller 72, and a brushless motor 73 is arranged at the center rotation position of the first belt pulley 33 or the second belt pulley 63. The brushless motor 73 is arranged in a manner similar to that of a battery car structure in the prior art, the brushless motor 73 is arranged in a rotation central hole of the first belt pulley 33 or the second belt pulley 63, and the first belt pulley 33 or the second belt pulley 63 is similar to a tire of the battery car. The brushless motor 73 is used to drive the first pulley 33 or the second pulley 63 to rotate. Alternatively, the brushless motor 73 may be mounted on both the first pulley 33 and the second pulley 63. The power module 71, the display screen 74, the variable frequency controller 72 and the brushless motor 73 are all electrically connected together. The brushless motor 73 is used for resisting the rotation of the first pulley 33 or the second pulley 63, so as to further provide an external auxiliary traction power for the patient, so that the patient feels more comfortable, especially in the early stage of traction rehabilitation training.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
