Example 1

As shown in fig. 1, the embodiment discloses an orthopedic traction frame, which includes a frame 1, a guide wheel assembly 4, a traction rope 3, and a counterweight 7. Specifically, this leading wheel subassembly 4 sets up on support 1, and the one end of haulage rope 3 is connected with balancing weight 7 after bypassing leading wheel subassembly 4, and the other end of haulage rope 3 is then connected on the limbs that the patient need pull during the use, comes to pull patient's limbs through balancing weight 7 self gravity. During the concrete implementation, can set up the couple on the haulage rope 3, can set up the link on the balancing weight 7, conveniently connects balancing weight 7.

In order to prevent the counterweight 7 from shaking, as shown in fig. 1, the support 1 is provided with a clamping component 5 and a limiting component 6, the traction rope 3 sequentially passes through the clamping component 5 and the limiting component 6 from top to bottom, namely, the clamping component 5 is close to one side of the limb of the patient, and the limiting component 6 is close to one side of the counterweight 7.

As shown in fig. 5, the limiting assembly 6 includes an outer ring 61 connected to the bracket 1, an inner ring 62 connected to the inside of the outer ring 61 by a spring 63, and the traction rope 3 passes through the inner ring 62. The inner race 62 is fixed inside the outer race 61 by a spring 63, and the inner race 63 is movable inside the outer race 61.

When balancing weight 7 swings, haulage rope 3 extrudees inner circle 62 and makes spring 63 compress, can inject the swing range of balancing weight 7 through inner circle 62, also makes the slow stop motion of balancing weight 7 through the cushioning effect of spring 63, prevents that balancing weight 7 swing range is too big and causes the secondary damage for the patient.

In addition, the clamping assembly 5 comprises two clamping parts respectively connected with the bracket 1, the two clamping parts are oppositely arranged, and the traction rope 3 is clamped between the two clamping parts.

Specifically, as shown in fig. 4, the clamping member includes a U-shaped mounting block 53 connected to the bracket 1 through a connecting rod 51, and a limiting wheel 52 mounted on the U-shaped mounting block 53, and the traction rope 3 is clamped between the limiting wheels 52 of the two clamping members.

During installation, limiting wheel 52 is installed in the U-shaped groove of U-shaped installation block 53 through the round pin axle to limiting wheel 52 can rotate around the round pin axle, because limiting wheel 52 can rotate, so haulage rope 3 can reciprocate and can not swing, can prevent like this the balancing weight 7 swing, does not influence the angle of adjusting haulage rope 3 again.

In order to be able to adjust the angle of the traction rope 3, the present application is made applicable to no-patient use. As shown in fig. 2 and 3, the guide wheel assembly 4 includes a support rod 48, an angle adjustment assembly, a mounting rod 43, and a guide wheel 41. One end of the support rod 48 is connected to the bracket 1, the other end thereof is connected to one end of the mounting rod 43 through the angle adjustment assembly, the guide wheel 41 is mounted to the other end of the mounting rod 43, and the traction rope 3 bypasses the guide wheel 41 and is supported by the guide wheel 41.

The angle adjustment assembly can adjust the angle between the mounting rod 3 and the support rod 48. Specifically, the angle adjusting assembly comprises a first adjusting head 42 arranged at the upper end of the supporting rod 48, a threaded rod 45 arranged on the first adjusting head 42, a second adjusting head 44 arranged at the lower end of the mounting rod 43, and a locking nut 46 arranged on the threaded rod 45. During installation, the locking nut 46 is taken down, the second adjusting head 44 is sleeved on the threaded rod 45, the locking nut 46 is installed on the threaded rod 45, the second adjusting head 44 is locked through the locking nut 46, and the installation rod 43 is further fixed. In specific implementation, the height positions of the clamping component 5 and the limiting component 6 are set according to actual conditions, and the angle adjustment of the mounting rod 43 is not affected.

In order to make the limbs of the patient more comfortable, the support 1 is provided with a cushion block 2, and the cushion block 2 is relatively provided with two limiting plates. This cushion 2 is sponge material, and the limbs that the patient need pull during the use are placed between two limiting plates, carry on spacingly by two limiting plates. Fix the haulage rope 3 on patient's limbs, adjust installation pole 43 to suitable angle, fix balancing weight 7 on haulage rope 3 at last, pull the limbs through the balancing weight.

Example 2

In the present embodiment, in addition to embodiment 1, the stopper teeth 47 that can be engaged with each other are provided on both surfaces of the first adjustment head 42 and the second adjustment head 44 that are bonded to each other. During the use, adjust the angle of installing pole 43 earlier to with first regulation head 42 and the mutual laminating of second regulation head 44, the spacing latch 47 on first regulation head 42 and the second regulation head 44 is block each other this moment, again with lock nut 46 locking can, because spacing latch 47 on first regulation head 42 and the second regulation head 44 is block each other, consequently can restrict the rotation of installing pole 43, improve the stability of installing pole 43.

It should be noted that all of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except for mutually exclusive features and/or steps.

In addition, the above embodiments are exemplary, and those skilled in the art can devise various solutions in light of the disclosure, which are also within the scope of the disclosure and the protection scope of the present invention. It should be understood by those skilled in the art that the present specification and drawings are illustrative only and are not limiting upon the claims.
