[0032] Refer to Figures 1 to 6 As shown, a lumbar and back rehabilitation training device includes a support mechanism 1, an adjustment mechanism 2 and a protection mechanism 3, and is characterized in that: the support mechanism 1 includes a bed frame 11 and a movable trough frame 12 slidably connected below the bed frame 11. A slide rail mechanism can be used to realize the sliding between the bed frame 11 and the movable trough frame 12. Sliders are provided on both sides of the movable trough frame 12, and slide rails matching the sliders are provided on both sides inside the bed frame 11. The adjustment mechanism 2 includes a first limit component 21 arranged in the middle inside the movable trough frame 12, a connecting block 23 arranged on the first limit component 21, a pressing component 24 rotatably connected to the connecting block 23, a first slide rail mechanism 22 arranged at both ends inside the movable trough frame 12, and a second limit component 25 arranged on both sides of the bed frame 11. The protection mechanism 3 includes a connecting plate 31 arranged on the first limit component 21 and the first slide rail mechanism 22, a second slide rail mechanism 32 arranged on the connecting plate 31, a protection foot plate 33 arranged on the second slide rail mechanism 32, and a protection shoulder plate 34 arranged on the second limit component 25.

[0033] A mattress 111 is provided above the bed frame 11.

[0034] A handle 121 is provided at the front end of the movable trough frame 12 to facilitate the stretching of the movable trough frame 12.

[0035] The first limiting component 21 includes a first limiting rod 211 fixedly connected to the middle inside the moving groove frame 12, a plurality of first limiting grooves 212 uniformly arranged on the upper surface of the first limiting rod 211, and a first limiting block 213 slidably connected to the first limiting rod 211 in a matching manner. Both ends of the first limiting rod 211 are provided with chutes, and both ends inside the first limiting block are provided with rollers that slide on the chutes.

[0036] The connecting block 23 is fixedly connected to the rear end of the first limiting block 213. One end inside the connecting block 23 is provided with an empty groove 231, and the other end is provided with a groove 232. The empty groove 231 communicates with the groove 232, and a through hole 233 is provided at the lower end of the empty groove 231.

[0037] The pressing component 24 includes a connecting rotating rod 241, a limiting block 242, a spring 243, and a pressing plate 244. The middle of the connecting rotating rod 241 is rotatably connected to the groove 232. Both ends of the middle of the connecting rotating rod 241 are provided with rotating shafts, and both sides of the groove 232 are provided with slot holes. The rotating shafts are slidably connected to the slot holes. The lower end of the connecting rotating rod 241 extends through the groove 232 and into the empty groove 231. The lower end of the connecting rotating rod 241 is fixedly connected to the limiting block 242. A spring 243 is fixedly connected between the lower end of the connecting rotating rod 241 and the upper end of the empty groove 231. The upper end of the connecting rotating rod 241 extends outside the groove 232 and the upper end of the connecting rotating rod 241 is fixedly connected to the pressing plate 244. The size of the through hole 233 is larger than the end face size of the limiting block 242, ensuring that the limiting block 242 can rotate out of the through hole 233 when the connecting rotating rod 241 rotates. The limiting block 242 cooperates with the limiting block 242. The lower end of the limiting block 242 is a bevel structure, enabling the limiting block 242 to be inserted into or removed from the first limiting groove 212.

[0038] When the user presses the pressing plate 244, the pressing plate 244 presses down to drive the connecting rotating rod 241 to rotate. The lower end of the connecting rotating rod 241 rotates upward, causing the limiting block 242 to disengage from the limiting block 242 and the through hole 233. At this time, the spring 243 between the lower end of the connecting rotating rod 241 and the empty groove 231 is in a compressed state. When the pressing plate 244 is pressed, the connecting plate 31 can move under the sliding action of the first limiting component 21 and the first sliding rail mechanism 22, moving the distance of the protective foot plate 33.

[0039] The middle of the bottom end of the connecting plate 31 is fixedly connected to the first limiting block 213, and both sides of the bottom end of the connecting plate 31 are fixedly connected to the surfaces of the first sliders of the first sliding rail mechanism 22.

[0040] The bottom end of the protective foot plate 33 is fixedly connected to the surface of the second slider of the second sliding rail mechanism 32. A protective baffle 331 is provided on the protective foot plate 33. Some anti-slip bumps can be provided on the protective foot plate 33.

[0041] The structures of the first slide rail mechanism 22 and the second slide rail mechanism 32 are composed of a slide rail, a slider slidably connected to the slide rail in a mating manner, and limit blocks at both ends of the slide rail. The frictional resistance between the slider and the slide rail of the second slide rail mechanism 32 can be appropriately increased so that the slider can slide on the slide rail while increasing a certain amount of resistance. This can help control the sliding speed and stability, prevent the slider from sliding freely at will, and thus improve the safety and controllability of the training device.

[0042] The second limit assembly 25 includes second limit rods 251 fixedly connected to both sides of the bed frame 11, a plurality of second limit grooves 252 uniformly arranged on the surface of the second limit rods 251, second limit blocks 253 slidably connected to the second limit rods 251 in a mating manner, and limit insertion rods 254 arranged on the second limit blocks 253 and mating with the second limit grooves 252. The sliding connection manner between the second limit rods 251 and the second limit blocks 253 is the same as the sliding connection manner between the first limit rods 211 and the first limit blocks 213 in this embodiment. The limit insertion rods 254 can be threaded insertion rods, and then the second limit grooves 252 can be threaded holes mating with the threaded insertion rods; the limit insertion rods 254 can also be elastic automatic pins, and the second limit grooves 252 cooperate with the pins.

[0043] The protective shoulder plate 34 includes a fixed groove plate 341 fixedly connected to one side of the second limit block 253, a movable shoulder plate 342 slidably connected to the fixed groove plate 341, and a flexible pad arranged on the surface of the movable shoulder plate 342. The flexible pad can relieve the pressure between the shoulder and the movable shoulder plate 342 and avoid discomfort or pain caused by long-term contact. Slide rails are provided on the upper and lower sides inside the movable shoulder plate 342, and sliders are provided on both sides of the fixed groove plate 341 and are connected to the slide rails in a mating manner. The frictional resistance between the slide rails of the movable shoulder plate 342 and the sliders of the fixed groove plate 341 can also be appropriately increased to ensure that the movable shoulder plate 342 can be more stable and controlled during the sliding process and prevent it from sliding freely at will.

[0044] Embodiment 2

[0045] The operating principle of the present utility model:

[0046] When the user uses the device for back bridge training, first pull out the limit insertion rod 254, move the second limit block 253, and move the protective shoulder plate 34 along the side of the bed frame 11 through the second limit rod 251 to adjust the distance of the protective shoulder plate 34 and align it.

[0047] The user pulls the handle 121 to move the movable groove frame 12 out of the bed frame 11. Press the pressing plate 244, and then lie on the bed frame 11, making the buttocks close to the end of the bed frame. The user adjusts the protective shoulder plate 34 according to his own situation and pulls the movable shoulder plate 342 inside the protective shoulder plate 34 so that the movable shoulder plate 342 can protect the shoulders.

[0048] Subsequently, the user steps on the protective footboards 33 with both feet and can adjust the distance between the protective footboards 33 by exerting force with both feet. Then the user can step on one of the protective footboards 33 and use the heel of the other foot to step on the pressing plate 244, and use the foot force to push the connecting plate 31, so that the connecting plate 31 moves in the moving groove frame 12 through the first slide rail mechanism 22 and the first limiting component 21, thereby adjusting the position between the protective footboard 33 and the buttocks according to the user's own conditions and making the user's knees bend.

[0049] After completing the preparatory movement, the user places both arms flat on the mattress 111, or bends the arms and places both elbows on the mattress 111, tightens the abdominal muscles and gluteal muscles, and slowly lifts the buttocks off the ground until the body forms a straight line from the shoulders to the knees, taking care not to let the lower back arch excessively. Hold for a few seconds, then slowly lower the buttocks back to the starting position to complete one set of training. The user can specify the number of training sets according to their own situation.

[0050] In addition, on the basis of this bridge exercise training, while maintaining the bridge exercise posture, alternately lift one leg so that the lifted leg is in a straight line with the body. Hold each leg lift for a few seconds, then change to the other leg, and cycle through the groups for training.

[0051] The bridge exercise training not only has a significant effect on the rehabilitation of the lumbar and dorsal regions, but also has an indirect rehabilitative effect on the shoulders and arms. The bridge exercise training requires the scapulae to stably support the weight of the body, which helps to strengthen the muscles around the scapulae, including the rhomboid muscles and the trapezius muscles, thereby improving the stability of the scapulae and enhancing the arm strength and endurance at the same time.
