Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation training equipment, in particular to an upper limb training adjustment device. Background Art

[0002] For patients with upper and lower limb disabilities, rehabilitation training is an important part of eliminating or alleviating upper and lower limb disabilities. The main purpose of rehabilitation training is to enable the patient's upper and lower limb joints to move and gradually restore the muscle and nerve functions related to upper and lower limb activities. Upper and lower limb active and passive motion rehabilitation machines are common equipment for patients to perform upper and lower limb rehabilitation training. Upper and lower limb active and passive motion rehabilitation machines usually use motor drive to drive the patient's upper and lower limbs to perform active training, passive training, or active and passive training.

[0003] In order to ensure the training effect and comfort of patients during training, different patients need to switch the upper and lower limb active and passive motion rehabilitation machines according to their own usage needs and the convenience of medical staff's operation. The upper limb training table's vertical mode and parallel mode rotation switch, the upper limb training table's left and right rocker arm interactive mode and parallel mode rotation switch. Existing upper and lower limb active and passive motion rehabilitation machines often find it difficult to have structures for adjusting the above parameters at the same time, and the structures for adjusting the above parameters are often more complicated, which is not convenient for patients to adjust, affecting patients' user experience and training effects.

[0025] The following is combined with Figure 1-4 , the embodiments of the utility model are further described in detail.

[0026] An upper limb training adjustment device 1 is used to switch between a vertical mode and a parallel mode of upper limb training. Figure 1 , 2 As shown, it includes a swivel seat 11, an upper limb skeleton 12, a spring plunger 13, a limit screw 14 and a hand screw 15. One end of the swivel seat 11 is used for fixed support. The other end of the swivel seat 11 is provided with an adjustment slot 114. The upper limb skeleton 12 includes a rotating portion 121 and a mounting portion 122. The rotating portion 121 is rotatably arranged in the adjustment slot 114, and one end of the rotating portion 121 away from the swivel seat 11 is fixedly connected to the end of the mounting portion 122, and the mounting portion 122 is provided with a mounting slot 123 with an open upper end. At least two positioning slots 1211 are provided on the rotating portion 121, and the two positioning slots 1211 are arranged at intervals along the circumference of the rotating portion 121 for adjusting the orientation of the upper limb skeleton 12. One end of the spring plunger 13 passes through the swivel seat 11 and is clamped in the positioning slot 1211. A screw hole 1213 is disposed on the circumference of the other end of the rotating base 11 . One end of the hand screw 15 is threadedly connected to the screw hole 1213 and the end thereof abuts against the circumference of the rotating portion 121 to fix the rotating portion 121 .

[0027] Among them, the swivel seat 11 includes a fixing part 111 and a bearing part 112. The fixing part 111 is set as a cylindrical structure. The fixing part 111 is provided with a clamping groove 113 which passes through from top to bottom. The fixing column is sleeved in the clamping groove 113, and the fixing column is fixedly connected to the fixing part 111 by screws. The fixing part 111 is provided with a vertical plane on both sides along its axial direction, and a plurality of reserved mounting holes are provided on the vertical plane to facilitate the installation of other components. Among them, the armrest is fixedly installed on the vertical plane. The bearing part 112 is arranged on one side of the fixing part 111, and an adjustment groove 114 is provided on the bearing part 112, and the connecting groove is connected to the clamping groove 113. The bearing part 112 is set as a square structure, and the display screen is fixedly arranged above the bearing part 112 to facilitate user operation.

[0028] Specifically, a fixing hole that penetrates inside and outside is also provided on the peripheral side of the bearing portion 112 of the swivel seat 11. The spring plunger 13 includes a movable rod 131, a return spring 132 and a plug seat 133. The interior of the plug seat 133 is hollow, one end of the plug seat 133 is open and clamped in the fixing hole, and the other end of the plug seat 133 is provided with an inner hole. One end of the movable rod 131 abuts against the end of the plug seat 133, and the other end of the movable rod 131 passes through the inner hole and the fixing hole is clamped in the positioning groove 1211. The return spring 132 is sleeved on the peripheral side of the other end of the movable rod 131, one end of the return spring 132 is abutted and connected with the other end of the movable rod 131, and the other end of the return spring 132 abuts against the inner wall of the plug seat 133, thereby improving the automatic reset effect of the spring plunger 13 and making it more convenient to use.

[0029] The size of the middle section of the movable rod 131 is smaller than the diameter of the inner hole, and the return spring 132 is sleeved on the middle section, which is convenient for limiting the return spring 132 and improving the assembly efficiency.

[0030] The other end of the movable rod 131 is set to a conical structure, and the cross-sectional area along the central extension direction of the rotating part 121 is set to decrease gradually, so as to improve the insertion accuracy and reduce the friction resistance. The movable rod 131 and the rotating part 121 can be set to a metal structure, which can improve the service life. Moreover, when the movable rod 131 enters the positioning groove 1211, there is an obvious metal collision sound feedback, so that the user knows that it is in place, which is more convenient to use.

[0031] In order to improve the convenience of operation, the movable rod 131 can be protruded from the plug seat 133, and a pull ring 134 can be sleeved on the end of the movable rod 131531 to facilitate the user to pull out the movable rod 131.

One end of the limit screw 14 passes through the rotating seat 11 and is threadedly connected in the fixing groove 1212, thereby improving the stability of the equipment during training.

[0033] The limit screw 14 , the spring plunger 13 and the hand screw 15 are staggered along the length direction of the rotating part 121 , which is beneficial to ensure the strength of the rotating part 121 and enhance the safety performance.

[0034] When in use, manually loosen the hand screw 15, pull out the spring plunger 13, rotate the upper limb frame 12, the end of the spring plunger 13 separates from the positioning slot 1211 and contacts the peripheral side of the rotating part 121, and loosen the spring plunger 13. After the upper limb frame 12 is rotated into place, the return spring 132 of the spring plunger 13 pushes the movable rod 131 into the corresponding position of the positioning slot 1211, so that the upper limb frame 12 can no longer rotate, and the movable rod 131 enters the positioning slot 1211 with obvious metal collision sound feedback, letting the user know that it is in place. Tighten the hand screw 15 again to start training. The equipment is highly user-friendly and greatly improves the product's operating performance.

[0035] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
