[0002] In the field of medical rehabilitation, medical braces are widely used as auxiliary treatment tools for fracture fixation, joint protection, and sports injury recovery. Currently, the most common medical brace connection devices on the market mostly use traditional mechanical locks or Velcro designs. While these devices achieve brace fixation and adjustment to a certain extent, they have several significant drawbacks. For example, traditional locks often require two hands to operate, making adjustment particularly difficult for patients with unilateral limb injuries. Furthermore, traditional locks are not convenient for limiting the range of motion of the patient's joints.
[0003] In view of this, the inventor specially designed an angle adjustment connection device, which resulted in the present invention. Utility Model Content
[0004] The purpose of the present utility model is to provide an angle adjustment connection device, which can not only easily complete the adjustment and locking operation mechanism with one hand, but also freely set the maximum bending of the joint within a certain range, effectively preventing re-injury caused by excessive activity, and providing better protection for the patient's rehabilitation exercises.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] The two wheels are connected to each other and are adapted to move the two wheels together so as to allow the two wheels to move freely in the rotation of the steering column and to move the steering column to a desired position.
[0007] Furthermore, the angle adjustment assembly includes a base, a limit block, a limit rod and a return spring; the lower end of the base is arc-shaped and matches the ring of the calf brace between the outer plate and the inner plate; the limit block is embedded in the base and can be taken out upward; the two ends of the limit rod pass through the side surfaces of the limit block and the base in turn and the ends of the two sides of the limit rod are respectively embedded in the sliding grooves of the outer plate and the inner plate, and the limit rod is used to limit the sliding of the limit block and the upward removal; the two ends of the return spring are fixedly connected to the lower end of the limit block and the bottom surface inside the base respectively; the outer side of the base is fixedly connected to one end of the fixing bar.
[0008] Furthermore, the sliding slot is formed into a plurality of continuously arranged grooves on one side of the outer edge of the outer plate and the inner plate, and the limit block is pushed upward by the reset spring to embed the two ends of the limit rod into the grooves.
[0009] Furthermore, a plurality of fixing holes are symmetrically provided on the fixing protrusion, and the brace on one side of the thigh is fixedly connected to the connecting device through bolts and the fixing holes.
[0010] Furthermore, the sliding groove is made of metal.
[0011] Furthermore, the outer edge of the fixing protrusion is rounded.
[0012] Furthermore, the upper end surface of the limit block is wavy.
[0013] Furthermore, an angle ruler corresponding to the sliding groove is provided on the outer circumference of the outer plate.
[0014] Furthermore, the upper fixing bar and the lower fixing bar are provided with indicating openings, and the numbers in the indicating openings are the sliding angle ranges of the calf brace in the corresponding sliding grooves.
[0015] After adopting the above technical solution, the utility model has the following beneficial effects:
[0016] 1. The unique design of this utility model allows patients to complete angle adjustment and locking with just one hand, which greatly improves the convenience of use, especially for patients with unilateral limb injuries.
[0017] 2. The interplay of the sliding grooves, angle adjustment components, and fixing bars between the outer and inner plates of this invention allows for precise control of the brace's connection angle. Patients can adjust the position of the limiter rod within the sliding groove to limit the brace's maximum range of motion, effectively preventing secondary injuries caused by excessive movement.
[0018] 3. The utility model can allow patients to clearly understand the current range of calf brace activity angles through the angle ruler provided on the outer panel and the indication openings on the upper fixing bar and the lower fixing bar, making adjustment easier.
