Technical Field
[0001] The utility model relates to the technical field of rehabilitation training, and more specifically, to an upper limb rehabilitation traction device with convenient angle adjustment. Background Art
[0002] Upper limb rehabilitation is an important treatment for patients with limited upper limb function due to trauma, surgery, nerve damage, fractures, or chronic diseases (such as stroke and arthritis). Effective rehabilitation training can significantly improve patients' motor skills, daily living abilities, and quality of life. With the advancement of medical technology, the types and functions of rehabilitation devices have continued to expand. Among them, upper limb rehabilitation traction devices are increasingly being used clinically due to their scientific nature and applicability.
[0003] Traditional upper limb rehabilitation equipment mostly adopts a fixed-angle design. During the rehabilitation process, the patient's forearm cannot be bent to a large extent due to injury, and the user cannot control the bending range well. In this case, the patient may inadvertently push the joint beyond the safe range during rehabilitation training, resulting in re-injury or aggravation of the original injury. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an upper limb rehabilitation traction device with easy angle adjustment, aiming to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an upper limb rehabilitation traction device with easy angle adjustment, comprising a base as a carrier of the entire device, a support pad fixedly connected to the base, and an exercise mechanism for arm training, wherein the exercise mechanism comprises a bracket hinged on the support pad, a handle fixedly connected to the bracket, a U-shaped bar fixedly connected to the bracket, an inclined plate fixedly connected to the base, a box body slidably connected to the inclined plate, a counterweight block installed in the box body, a transmission rope fixedly connected between the U-shaped bar and the box body, and an adjustment mechanism for changing the maximum rotation angle of the bracket is also provided on the base.
[0006] Furthermore, a sliding groove is provided on the inclined plate, and a sliding block is fixedly connected to the bottom of the box body and is slidably connected to the sliding groove.
[0007] It can be seen that in the above technical solution, displacement of the box body can be avoided.
[0008] Furthermore, a transmission shaft is fixedly connected in the base, and a limiting wheel is sleeved on the transmission shaft and is slidably connected to the transmission rope.
[0009] It can be seen that in the above technical solution, it is ensured that the transmission rope can slide at the corresponding position to prevent it from shifting and causing damage.
[0010] Furthermore, a rotating rod and a screw are rotatably installed in the box body, and bevel gears for meshing transmission are mounted on the screw and the rotating rod. A screw sleeve is threadedly connected to the screw, and the end of the screw sleeve is fixedly connected to a limit block, and the bottom of the limit block is in contact with the inclined plate.
[0011] Furthermore, a plurality of counterweight blocks are provided for adjusting the training intensity.
[0012] Furthermore, the support pad is fixed with a limiting belt to prevent the upper arm from shifting.
[0013] The technical effects and advantages of this utility model are:
[0014] 1. This utility model is equipped with an exercise mechanism. By holding the handle and pulling the bracket toward the body, the U-shaped bar moves with the bracket. The bracket pulls the box body upward along the inclined plate through the transmission rope, which can perform rehabilitation exercises for the arm. Only a simple pulling action is required to carry out the exercise. It is suitable for patients with different abilities and rehabilitation stages and is easy to understand and operate.
[0015] 2. The utility model sets an exercise mechanism and adjusts the position of the limit block to limit the movement of the box body on the inclined board. The box body cannot continue to move obliquely upward to the inclined board, and the bracket cannot continue to rotate, thereby controlling the bending degree of the forearm, reducing the risk of injury caused by excessive bending, and protecting the patient's joints and muscles.

[0025] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0026] Example 1:
[0027] Combine Figure 1-Figure 3 As shown, the present invention provides an upper limb rehabilitation traction device with easily adjustable angle, comprising a base 100 as a carrier of the entire device, a support pad 101 fixedly connected to the base 100, and an exercise mechanism 200 for arm training, so as to effectively exercise arm muscles, enhance muscle strength and endurance, and help restore function;
[0028] Different patients require different training intensities during rehabilitation. Reasonable control of intensity can ensure that each patient can train within a range that suits them, thereby more effectively restoring their functions. In order to solve the above problem, the exercise mechanism 200 includes a bracket 201 hinged on the support pad 101, a handle 202 fixed to the bracket 201, a U-shaped bar 203 fixed to the bracket 201, an inclined plate 206 fixed to the base 100, a box body 204 slidably connected to the inclined plate 206, a counterweight block 205 installed in the box body 204, and a transmission rope 21 fixed between the U-shaped bar 203 and the box body 204. 0, the user places his upper arm on the support pad 101, then holds the handle 202 and pulls the bracket 201 toward the body. The U-shaped bar 203 moves with the bracket 201, and the bracket 201 pulls the box body 204 to slide upward along the inclined plate 206 through the transmission rope 210. Then the bracket 201 is reset, and the box body 204 also slides under the inclined plate 206. Repeat the above steps to perform rehabilitation exercises for the arm. Exercises can be carried out with a simple pulling action. It is suitable for patients with different abilities and rehabilitation stages and is easy to understand and operate.
[0029] The base 100 is also provided with an adjustment mechanism 300 for changing the maximum rotation angle of the bracket 201, which can limit the transmission angle of the bracket 201, thereby ensuring that the forearm can only bend to a certain extent, avoiding injury to the forearm due to excessive bending after injury.
[0030] Specifically, a sliding groove 207 is provided on the inclined plate 206 , and a slider slidably connected to the sliding groove 207 is fixed to the bottom of the box body 204 , which can prevent the box body 204 from shifting.
[0031] Furthermore, a transmission shaft 208 is fixedly connected to the base 100, and a limiting wheel 209 is mounted on the transmission shaft 208 and is slidably connected to the transmission rope 210. The setting of the limiting wheel 209 ensures that the transmission rope 210 can slide at the corresponding position to prevent it from shifting and causing damage.
[0032] Excessive training intensity may cause damage to muscles, joints or ligaments, especially in the early stages of rehabilitation. Controlling intensity can reduce the risk of re-injury. In order to solve the above problem, multiple counterweights 205 are provided to adjust the training intensity. The more counterweights 205 there are, the greater the force required to rotate the bracket 201, and vice versa. Patients can adjust the number of counterweights 205 according to their own feelings to avoid injuries or excessive fatigue caused by excessive training intensity, thereby performing rehabilitation exercises more safely.
[0033] According to the embodiments, this method not only exercises the strength of the arms, but also improves the flexibility of the shoulder joint, elbow joint and wrist, and comprehensively promotes the recovery of upper limb function.
[0034] Example 2:
[0035] If there is a lack of proper control, the patient may unconsciously take the wrong action, such as over-reliance on other limbs to assist in completing the action. Once such a habit is formed, it may affect the long-term functional recovery. In order to solve the above problems, combined with Figure 2 and Figure 4When the support frame 201 is in the state of being rotated, the support frame 201 of the user can be rotated to the left or right of the support frame 201, thereby preventing the support frame 201 from rotating.
[0036] Specifically, the support pad 101 is fixed with a limiting belt 102 to prevent the upper arm from shifting, which can fix the upper arm to a certain extent.
[0037] Through the above embodiment, it can be seen that: first, the user adjusts the intensity of training according to his own condition, and puts the counterweight 205 of corresponding strength into the box body 204. Then, according to the condition of his own arm, the rotating rod 302 is rotated. The rotating rod 302 drives the screw 301 to rotate through the bevel gear 303. The rotation of the screw 301 causes the limit block 305 on the screw sleeve 304 to move. Adjusting the position of the limit block 305 can limit the position of the box body 204 on the inclined plate 206, and the box body 204 cannot continue to move toward the inclined plate 206. The bracket 201 moves diagonally upward and cannot continue to rotate. The bending degree of the forearm is controlled. The user then places the upper arm on the support pad 101 and then holds the handle 202 to pull the bracket 201 toward the body. The U-shaped bar 203 moves with the bracket 201. The bracket 201 pulls the box body 204 to slide upward along the inclined plate 206 through the transmission rope 210. The bracket 201 is then reset and the box body 204 also slides below the inclined plate 206. Repeat the above steps to perform rehabilitation exercises for the arm.

In this technical solution, the electrical control components not mentioned are not shown in the figure because they belong to the existing technology and are not described here.
[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
