[0047] See also Figure 1, a lumbar muscle strain auxiliary rehabilitation device, including a base 100, a lumbar support assembly 200 is fixedly installed in the middle of the upper surface of the base 100, two groups of slide rails 300 are fixedly installed on the top of the base 100, the slide rails 300 are arranged along the length direction of the base 100, and two groups of slide seats 400 are slidably connected to the slide rails 300, and the two groups of slide seats 400 are respectively located on the left and right sides of the lumbar support assembly 200; the top of the right slide seat 400 is rotatably connected to the leg support assembly 500, and the top of the left slide seat 400 is rotatably connected to the trunk support assembly 600, and the right end of the trunk support assembly 600 is fixedly installed with a shoulder support assembly 700; a spacing adjustment assembly 800 is arranged between the two groups of slide seats 400, and a deflection drive assembly 900 is arranged above the two groups of slide seats 400, and the deflection drive assembly 900 is used to drive the leg support assembly 500 and the trunk support assembly 600 to deflect.

[0048] By manually driving the spacing adjustment component 800, the two sets of slide seats 400 are driven to move toward each other along the slide rail 300, which is convenient for users of different heights to use. The user lies prone on the waist support component 200, and then the deflection drive component 900 drives the leg support component 500 and the trunk support component 600 to deflect relative to each other, assisting the user to complete the "Little Flying Swallow" action. The user can lie on his back on the waist support component 200, with his shoulders against the shoulder support component 700 and his feet on the leg support component 500, so that the waist can be arched upward for rehabilitation training.

[0049] See also Figure 2-Figure 4 The lumbar support assembly 200 includes two groups of vertical plates 201 fixedly mounted on the top of the base 100. The two groups of vertical plates 201 are distributed front and back, and a connecting plate 202 is fixedly mounted between the two groups of vertical plates 201. The two vertical plates 201 are reinforced by the connecting plate 202. The top of the vertical plate 201 is an arc-shaped surface, and rollers 203 are equidistantly distributed along the arc-shaped surface between the two groups of vertical plates 201, so that when the patient lies on his back on the top of the rollers 203, they can fit the patient's waist. The two ends of the rollers 203 are respectively connected to the two groups of vertical plates 201 through rotation; the upper surface of the rollers 203 is provided with an array of hard protrusions 204, and the lower surface of the rollers 203 is fixedly installed with a sponge pad 205.

[0050] The hard protrusions 204 can be directed upward, and the patient can lie on the rollers 203 with the hard protrusions 204 contacting the patient's waist. The patient then steps on the leg support assembly 500, and the patient's waist can be moved forward and backward on the rollers 203 by exerting force with the legs, driving the rollers 203 to rotate, so that the hard protrusions 204 can continuously massage the patient's waist.

[0051] The sponge pad 205 can be directed upward, and when the patient lies prone on the roller 203 to perform the "Little Swallow" exercise, the hard protrusion 204 can be prevented from pressing on the patient's abdomen, making the patient more comfortable when lying prone.

[0060] See also Fig.11The spacing adjustment assembly 800 includes a mounting seat 801 fixedly mounted on the left side slide 400, a steel wire rope 802 fixedly mounted on the right side of the mounting seat 801, a U-shaped seat 803 fixedly mounted on the top of the right side slide 400, two sets of fixed pulleys 804 are rotatably connected in the U-shaped seat 803, a positioning tube 805 is fixedly mounted on the upper left side of the fixed shaft 2 602, the steel wire rope 802 first extends horizontally to the right, passes between the two sets of fixed pulleys 804, then extends horizontally to the left, and finally passes through the positioning tube 805, and a grip ring 806 is fixedly mounted on the other end of the steel wire rope 802. By holding the grip ring 806 and pulling the steel wire rope 802, the length of the steel wire rope 802 between the mounting seat 801 and the fixed pulley 804 is reduced, thereby reducing the spacing between the two sets of slides 400.

[0061] When in use, the handle 210 is held by hand to push the rotating arm 208 and the connecting shaft 207 to rotate, driving the arc-shaped rack 209 to move, thereby driving the gear 1 206 to rotate, so that the hard protrusion 204 faces the upper side;

[0062] The user lies on the roller 203 and steps on the fixed shaft 1 502. The bolt 2 403 can be inserted into the positioning hole 2 401 in advance to limit the right slide 400. Then, the user stretches and bends the legs to move the body back and forth on the roller 203, driving the sleeve 2032 to rotate relative to the support shaft 2031, so that the hard protrusion 204 massages the user's waist.

[0063] The bolt 403 is pulled out from the second positioning hole 401 to release the limiting effect on the two slides 400; the user lies on the roller 203 with his feet on the fixed shaft 502 and his shoulders against the arc plate 704, and then the holding ring 806 is pulled upward to reduce the length of the wire rope 802 between the mounting seat 801 and the fixed pulley 804, thereby reducing the distance between the two slides 400, so that the user's waist can be arched upward, and only supported by the feet and shoulders, and then the bolt 403 is inserted into the second positioning hole 401 to limit the slide 400, so that the patient maintains the current state; in addition, the slide 400 can also be not limited, and after holding the holding ring 806 with the hand, it moves up and down reciprocatingly, and with the force of the user's legs, the two slides 400 can be continuously switched between the movement states of moving toward and away from each other, so that the patient's waist arch angle is continuously changed, and at the same time, the patient's arms can be exercised;

[0064] By holding the handle 210, the rotating arm 208 and the connecting shaft 207 are rotated, and the arc-shaped rack 209 moves, thereby driving the gear 1 206 to rotate, so that the sponge pad 205 faces the upper side; the user then lies prone on the roller 203, and then pulls the grip ring 806 to reduce the distance between the two slides 400, so that the bearing plate 1 506 and the roller 1 505 support the legs, and the bearing plate 2 606 and the roller 2 605 support the torso;

[0065] Then insert bolt 2 403 into positioning hole 2 401 to limit the slide 400; finally, drive gear 3 903 to rotate through motor 904, drive gear 2 902 and drive shaft 901 to rotate, thereby driving two external threaded tubes 905 to rotate, so that slider 1 507 fits on the top of slide 400 and moves to the left, U-shaped frame 1 508 moves to the left synchronously, slide column 1 509 slides in guide groove 1 504, and pushes side plate 1 503 to deflect upward around fixed shaft 1 502, and adjusts the inclination angle of bearing plate 1 506;

[0066] Similarly, the second slide block 607 fits on the top of the slide seat 400 and moves to the right, the second U-shaped frame 608 moves to the right, the second slide post 609 slides in the second guide groove 604, and pushes the second side plate 603 to deflect upward around the second fixed axis 602, and adjusts the tilt angle of the second bearing plate 606;

[0067] Thereby, the user's torso and legs are bent upwards supported by the second support plate 606 and the first support plate 506, and maintain the "little flying swallow" state.
