[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0052] like Figures 1 to 7 As shown, this application proposes a dance-assisted backbend device, including a support assembly 100. The support assembly 100 includes a base plate 101, a support frame 102, and a support pad 103. The support frame 102 is fixed on the base plate 101, and the support pad 103 is located on the support frame 102. When performing backbend training, the support pad 103 contacts the waist of the person.

[0053] It also includes a movable plate 104, a fixed rod 105, and an auxiliary component 200; the auxiliary component 200 includes an auxiliary pad 201, a spiral rod 202, a sliding rod 203, a rotating rod 204, a guide rail 205, a gear 206, and a motor 209;

[0054] A guide rail 205 is fixed on the support frame 102, and a movable plate 104 is slidably connected to the guide rail 205; a support pad 103 is fixed to the movable plate 104 by a fixed rod 105, and the movable plate 104 drives the support pad 103 to move up and down; a motor 209 is fixed inside the base plate 101, and a screw rod 202 is fixed on the base plate 101, and the screw rod 202 can rotate on the base plate 101; gears 206 are fixed on the rotating shaft of the motor 209 and the screw rod 202 respectively, and the gears 206 located on the motor 209 and the screw rod 202 mesh with each other, and the motor 209 drives the screw rod 202 to rotate;

[0055] The base plate 101 has round holes on its opposite side walls. The sliding rod 203 is slidably connected to the round hole on the base plate 101. The sliding rod 203 is fixed to the base plate 101. When the sliding rod 203 slides to the outside of the round hole on the base plate 101, the support pad 103 is at its lowest point. When the sliding rod 203 slides to the inside of the round hole on the base plate 101, the support pad 103 is at its highest point. When the support pad 103 is at different heights, the bending radius will also be different. When the support pad 103 moves up and down, it will drive the rotating rod 204 to rotate. When the rotating rod 204 rotates, it will drive the sliding rod 203 to slide.

[0056] The two ends of the rotating rod 204 are rotatably connected to the support pad 103 and the sliding rod 203, respectively. The rotating rod 204 can rotate between the support pad 103 and the sliding rod 203, thereby adjusting the angle of the auxiliary pad 201 located on the rotating rod 204. The auxiliary pad 201 corresponds to different backbend ranges at different angles. When beginners perform backbend training, they can choose a suitable backbend range and continuously adjust the backbend range as the number of training sessions increases, so that beginners can gradually adapt to backbend training.

[0057] The screw rod 202 passes through the movable plate 104. The screw rod 202 is a threaded rod. The screw rod 202 and the movable plate 104 are threadedly connected. The movable plate 104 is driven to move up and down through the screw rod 202.

[0058] The rotating rod 204 is located on both sides of the support pad 103. The auxiliary pad 201 is fixed on the rotating rod 204. The auxiliary pad 201 is in contact with the back and the back of the thighs. When bending over, the auxiliary pad 201 can provide support and prevent falls due to instability.

[0059] Preferably, the guide rails 205 are fixed on the adjacent side walls of the support frame 102; the support frame 102 is a rectangular plate vertically fixed on the base plate 101, and there is a gap between the guide rails 205 and the upper and lower ends of the support frame 102; the guide rails 205 are T-shaped rods, and corresponding T-shaped grooves are opened on both sides of the movable plate 104, so that the guide rails 205 can be locked in the T-shaped grooves on the movable plate 104, so that the movable plate 104 can be fixed between the support frames 102.

[0060] Preferably, limit blocks 210 are fixed at both ends of the guide rail 205; the limit blocks 210 are rectangular blocks and are used to limit the movement range of the movable plate 104.

[0061] Preferably, the rotating rod 204 has multiple round holes spaced at equal intervals, and a sliding block 208 is slidably connected to the rotating rod 204; an auxiliary pad 201 is fixed to the sliding block 208; a bolt that mates with the round holes on the rotating rod 204 is rotatably connected to the sliding block 208, allowing the sliding block 208 to be fixed at any position on the rotating rod 204. When trainees of different heights perform backbend training, the auxiliary pad 201 is moved to a suitable position and then fixed by the bolt on the sliding block 208 and the round holes on the rotating rod 204, thus facilitating use by trainees of different heights.

[0062] Preferably, the rotating rod 204 is a rectangular rod; a rotating seat 207 is fixed to the bottom of the support pad 103 and the end of the sliding rod 203 respectively, and the rotating seat 207 is fixed to the support pad 103 and the sliding rod 203 by bolts; the two ends of the rotating rod 204 are rotatably connected to the rotating seat 207. When the support pad 103 moves up and down, the two ends of the rotating rod 204 rotate on the rotating seat 207, so that the included angle between the rotating rod 204 and the base plate 101 changes, thereby adjusting the angle of the auxiliary pad 201 fixed on the rotating rod 204.

[0063] Preferably, the support pad 103 is filled with a sponge layer, which is located on the upper surface of the support pad 103. When bending over, an overly firm support pad 103 will cause discomfort in the lower back. The sponge layer inside the support pad 103 is soft and can reduce discomfort in the lower back. The upper surface of the support pad 103 is a rounded surface, so that the lower back can fit against the upper surface of the support pad 103 when bending over.

[0064] Preferably, multiple air cushions are attached to the upper surface of the support pad 103. The air cushions can increase the friction between the human body and the support pad 103, preventing the person from falling off the device and getting injured during backbend training.

[0065] Preferably, the auxiliary pad 201 is filled with a sponge layer, which is located on the side of the auxiliary pad 201 that contacts the human body. The sponge layer can improve the comfort of the trainee during backbend training. There are two auxiliary pads 201, which are located on both sides of the support pad 103. The auxiliary pads 201 can contact the legs and back of the human body respectively. The auxiliary pads 201 can provide support during backbend training to prevent falls due to instability. At the same time, when the auxiliary pads 201 are at different angles, the coordination between the auxiliary pads 201 and the support pad 103 determines different backbend ranges, which allows beginners to gradually increase the backbend range according to their own flexibility, so that the flexibility of the beginners can be continuously improved.

[0066] Preferably, the movable plate 104 and the fixed rod 105 are welded and fixed; the top of the fixed rod 105 is fixed to the bottom of the support pad 103 by bolts. The fixed rod 105 is used to support and fix the support pad 103. The support pad 103 is detachably fixed to the top of the fixed rod 105, so that different support pads 103 can be replaced according to the changes in backbend training. Different support pads 103 have different arc angles on their upper surfaces, so that the backbend range during backbend training is also different. The appropriate support pad 103 can be selected according to the flexibility of the trainee.

[0067] Preferably, the backbend is greatest when the support pad 103 is at its highest point and lowest when the support pad 103 is at its lowest point. When beginners use it, as the number of training sessions increases, the support pad 103 rises from its lowest point, allowing the trainee's backbend to continuously increase, thereby improving the trainee's flexibility.

[0068] Preferably, the side of the auxiliary pad 201 that contacts the human body is an inclined surface with a rounded arc. The thickness of the sponge layer at the highest point of the upper surface of the auxiliary pad 201 is greater than the thickness of the sponge layer at the lowest point of the upper surface of the auxiliary pad 201. This ensures the comfort of the trainee's back and legs when bending over. During the bending over exercise, the auxiliary pad 201 can always maintain contact with the human body, so that the auxiliary pad 201 can maintain the support effect on the human body during the bending over process.

[0069] Preferably, the fixing rod 105 consists of two rectangular rods, and the spiral rod 202 is located between the fixing rods 105. The length of the fixing rod 105 is greater than the length of the spiral rod 202. When the movable plate 104 moves to the lowest point, a gap can be left between the top of the spiral rod 202 and the bottom of the support pad 103.

[0070] Preferably, the spiral rod 202 is a cylindrical rod, and a limiting block 210 is fixed at the top of the spiral rod 202. The limiting block 210 is located on the upper side of the movable plate 104 and is a circular piece. The limiting piece is used to fix the spiral rod 202 and the movable plate 104. When the movable plate 104 moves to the uppermost end of the spiral rod 202, the limiting block 210 can prevent the movable plate 104 and the spiral rod 202 from separating.

[0071] In practical use, a dance-assisted backbend device according to an embodiment of this application is as follows:

[0072] First, based on the trainee's flexibility, the motor 209 drives the gear 206 to rotate, which in turn drives the screw rod 202 to rotate. The screw rod 202 and the movable plate 104 are connected by threads, allowing the movable plate 104 to move up and down on the support frame 102, which in turn moves the support pad 103 up and down. When the support pad 103 moves, the rotating rod 204 located between the support pad 103 and the sliding rod 203 rotates. Simultaneously, the rotation of the rotating rod 204 causes the sliding rod 203 to slide. The angle between the auxiliary pad 201 on the rotating rod 204 and the base plate 101... The angle will also change. After adjusting to the appropriate position, the motor 209 stops running. During backbend training, the waist and the upper side of the support pad 103 are in contact, and the back of the thighs and the back are in contact with the auxiliary pad 201. The support pad 103 and the auxiliary pad 201 support the trainee together, causing the trainee's waist to arch. The different heights of the support pad 103 correspond to different degrees of back arching, thus achieving different degrees of backbend training. As the number of training sessions increases, the height of the support pad 103 is gradually increased, thereby increasing the degree of backbend and continuously improving the trainee's flexibility.

[0073] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
