DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example 1

[0017] See also Figures 1 to 3, which is the first embodiment of the utility model, and this embodiment provides a technical solution: a new type of lower limb rehabilitation assistive device, comprising a U-shaped plate 1 and an articulated seat 2, the two U-shaped plates 1 are hinged through the articulated seat 2, and the front surfaces of the two U-shaped plates 1 are provided with elastic straps for subsequently tying the U-shaped plates 1 to the patient's thigh or calf to realize the wearing of the entire protective device, the upper and lower surfaces of the articulated seat 2 are respectively provided with an axis rod 1 21 and an axis rod 22, the axis rod 1 21 and the axis rod 22 are respectively fixed to the two U-shaped plates 1, and an adjustable pad structure is provided on the U-shaped plate 1, and the adjustable pad structure includes a sponge pad 31, a strip slide 32, a strip base block 34 and a rear seat 35, the surface of the U-shaped plate 1 is provided with a strip slide 32 corresponding to the strip base block 34, and the sponge pad The sponge pad 31 is installed on the inner surface of the U-shaped plate 1. The sponge pad 31 is made of a soft sponge material and can play a certain protective role on a certain area of ​​the patient's lower limbs to prevent the skin in the area from being hard squeezed by the U-shaped plate 1 and causing discomfort. In particular, when there is an injured part in a certain area of ​​the patient's lower limbs, the position of the sponge pad 31 can be directly slid and adjusted to the injured area, thereby preventing the U-shaped plate 1 from causing hard squeezing of the injured area of ​​the lower limbs and improving the overall wearing comfort of the protective gear. The strip base block 34 is fixed on the rear surface of the sponge pad 31, and the strip base block 34 is slidably located in the strip slide 32. The rear end of the strip base block 34 extends to the rear surface of the U-shaped plate 1 and is movably connected to the rear seat 35. A movable component is provided between the rear seat 35 and the strip base block 34. Two limiting blocks 36 are symmetrically fixed to the surface of one side. A plurality of limiting slots 37 corresponding to the limiting blocks 36 are evenly opened on the rear surface of the U-shaped plate 1 relative to the two sides of the strip slide 32. The limiting block 36 is inserted into one of the limiting slots 37 to achieve stable limiting of the rear seat 35 and the sponge pad 31 during daily use, ensuring the stability of the sponge pad 31 at a certain height. Side sliders 341 are fixed to the two side surfaces of the strip base block 34. Side slide grooves 321 are opened on the inner walls of the two sides of the strip slide 32. The side sliders 341 slide in the side slide grooves 321 to achieve stable sliding of the strip base block 34 on the inner side of the strip slide 32. The movable components include an inner groove 38, an inner slider 39, a spring 310 and a connecting rod 311. The center of the rear seat 35 An inner groove 38 is provided inside the inner groove 38, and an inner slider 39 and a spring 310 are provided in the inner groove 38. A connecting rod 311 is fixed to the front surface of the inner slider 39, and the front end of the connecting rod 311 penetrates the front surface of the rear seat 35 and is fixedly connected to the strip base block 34. Under the pushing action of the spring 310, the limiting block 36 can be stably stuck in the limiting groove 37 during daily use, thereby ensuring the limiting stability of the rear seat 35, the strip base block 34 and the sponge pad 31. To adjust the position of the sponge pad 31 according to actual usage requirements, the rear seat 35 only needs to be pulled back so that the spring 310 is gradually compressed until the limiting block 36 moves out of the limiting groove 37, thereby releasing the limit on the rear seat 35 and realizing the up and down sliding of the rear seat 35 and the sponge pad 31.Thus, the height of the sponge pad 31 is changed. After the sponge pad 31 is adjusted to a suitable position, the rear clamping seat 35 is released, so that the spring 310 pushes the rear clamping seat 35 back to reset, and the limiting clamping block 36 can be clamped into the limiting clamping slot 37 at other positions, so that the rear clamping seat 35 and the sponge pad 31 can be limited again, thereby completing the height adjustment of the sponge pad 31.

[0018] One end of the spring 310 abuts against the inner wall of the inner groove 38 , and the other end of the spring 310 is in tight contact with the inner slider 39 , thereby ensuring the installation stability of the spring 310 .

[0019] A middle hole communicating with the inner groove 38 is formed through the center of the front surface of the rear clamping seat 35 , and the middle hole corresponds to the connecting rod 311 , so that the connecting rod 311 can pass through smoothly.

[0020] Wherein, side notches with rectangular cross-sections are provided on both side surfaces of the rear clamping seat 35 to facilitate subsequent operators to pull back the rear clamping seat 35 .

[0021] Example 2

[0022] See also Figures 1 to 3 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the anti-slip structure 33 can be set to prevent the sponge pad 31 from sliding away directly from the U-shaped plate 1 when adjusting the height, thereby avoiding unnecessary troubles during the adjustment process.

[0023] The anti-slip structure 33 includes an arc-shaped retaining bar 331 and a fastening bolt 332. The arc-shaped retaining bar 331 is rotatably mounted on the end surface of the U-shaped plate 1, and the arc-shaped retaining bar 331 covers the end opening of the strip slide 32. The front end of the arc-shaped retaining bar 331 is fixed to the U-shaped plate 1 by the fastening bolt 332. The end surface of the U-shaped plate 1 is provided with a threaded groove corresponding to the fastening bolt 332. The threaded end of the fastening bolt 332 passes through the end of the arc-shaped retaining bar 331 and is screwed into the threaded groove, so as to realize the stable fixation of the arc-shaped retaining bar 331 during daily use. When the operator slides the sponge pad 31, the arc-shaped retaining bar 331 is fixed to the U-shaped plate 1 by the fastening bolt 332. The retaining bar 331 can prevent the strip base block 34 from sliding directly out of the opening of the strip slide 32 due to misoperation, avoiding unnecessary trouble during the adjustment process. If the sponge pad 31 is to be removed from the inner side of the U-shaped plate 1 for cleaning and maintenance later, it is only necessary to loosen the fastening bolt 332 counterclockwise so that the threaded end of the fastening bolt 332 is screwed out of the threaded groove, and the arc retaining bar 331 is no longer limited. At this time, the arc retaining bar 331 can be rotated and removed from the opening of the strip slide 32, and no obstruction is caused to the strip base block 34. At this time, the rear seat 35 is pulled back and the sponge pad 31 is continuously pushed so that the strip base block 34 slides out of the end opening of the strip slide 32, and the sponge pad 31 can be easily removed.

[0024] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
