Description
Technical Field
[0001] This utility model relates to the field of dance training technology, and in particular to a hip-opening device for dance training. Background Technology
[0002] As is well known, dance training is a systematic and targeted activity aimed at comprehensively improving the user's physical fitness, dance skills, artistic expression, and understanding and interpretation of dance. In dance training, good hip flexibility is key to completing many dance movements. Hip-opening devices, through specific mechanical structures and adjustment functions, can help users safely and effectively perform hip extension and stretching training.
[0003] However, traditional dance training uses hip-opening devices, which usually put a lot of pressure and stretch on the hip muscles during hip-opening exercises, easily causing fatigue and soreness. Prolonged muscle tension not only affects the effect of the next training session, but may also lead to problems such as muscle strain and fatigue accumulation, increasing the risk of injury, prolonging recovery time, and thus affecting the continuity of dance training and the user's training enthusiasm. Therefore, technical improvements are urgently needed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hip-opening device for dance training. When in use, the servo motor drives a rotating column to rotate, simultaneously moving multiple sets of protrusions that continuously strike a push plate. The push plate, under pressure, compresses a return spring, causing its massage blocks to extend. The intervals of the protrusion rotation, combined with the extension and retraction of the return spring, cause the massage blocks to move back and forth, thus helping to relax tense muscle fibers and maintain their elasticity and flexibility. During the hip-opening movement that stretches the muscles, the synergistic effect of the massage prevents overstretching or tearing of the muscles.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A hip-opening device for dance training includes a base with a mounting cavity at the rear end of the base. A servo motor is fixedly connected to one side of the bottom surface of the mounting cavity, and an active rod is fixedly connected to the output end of the servo motor. A driven rod is rotatably connected to the other side of the bottom and top surfaces of the mounting cavity. A rotating rod is rotatably connected to the bottom surface of the mounting cavity near the driven rod. The upper ends of both the active rod and the rotating rod penetrate the mounting cavity to the outside of the mounting cavity and are fixedly connected to an auxiliary frame. A transmission wheel is sleeved in the middle of the active rod and the driven rod, and a synchronous belt is sleeved on the outer wall of the transmission wheel. An active gear and a driven gear are fixedly connected to the upper parts of the driven rod and the rotating rod, respectively.
[0007] Each auxiliary frame has a storage cavity inside. A servo motor is fixedly connected to one side of the inner wall at the rear end of the storage cavity. A rotating column is fixedly connected to the output end of the servo motor. Multiple protrusions are fixedly connected to the outer wall of the rotating column. Multiple return springs are fixedly connected to the inner wall on the other side of the storage cavity. A push plate is fixedly connected to the rear end of each return spring. Multiple massage blocks are fixedly connected to the outer wall on the other side of the push plate. Each massage block penetrates the storage cavity to the outside of the opposite side of the auxiliary frame.
[0008] Compared with existing hip-opening devices for dance training, this hip-opening device, when used, drives the active rod to rotate by starting the servo motor, which in turn drives the transmission wheel and synchronous belt on one side to rotate. This, in turn, drives the driven rod and active gear on the other side to rotate. The rotation of the active gear drives the driven gear and rotating rod to rotate in the opposite direction, thereby adjusting the angle of the auxiliary frames on both sides. It can continuously adjust the degree of hip opening as needed, and has high practical performance.
[0009] Furthermore, a backrest is fixedly connected to the rear end of the middle of the upper surface of the base, and a first connecting strap and a second connecting strap are fixedly connected to the lower part of both sides of the outer wall of the backrest, respectively. Fasteners and fastener bodies are fixedly connected to the outer walls of the adjacent sides of the first connecting strap and the second connecting strap, respectively.
[0010] Through the above technical solution, the backrest provides back support for users when performing hip-opening exercises, enabling users to maintain a correct sitting posture and avoid falling backward due to loss of balance during training.
[0011] Furthermore, the fastener and the fastener body are engaged in a snap-fit connection;
[0012] The above technical solution allows for the easy securing of the user's body to the backrest through the fasteners and snap-fit mechanism.
[0013] Furthermore, a PLC control panel is embedded in the middle of the upper surface of the base, and the PLC control panel is electrically connected to servo motor one and servo motor two respectively.
[0014] The above technical solution allows for easy control of its switching via a PLC control panel.
[0015] Furthermore, the driving gear and the driven gear mesh with each other;
[0016] The above technical solution facilitates the reverse rotation of the driven rod and the rotating rod by the meshing of the driving gear and the driven gear.
[0017] Furthermore, sliding grooves are provided on both sides of the upper surface of the base, and sliding columns are fixedly connected to the front end of the lower surface of the auxiliary frame;
[0018] The above technical solution facilitates improved fit through the use of sliding columns.
[0019] Furthermore, each of the sliding columns is slidably connected to the inner wall of the groove;
[0020] The above technical solution improves the stability of the auxiliary frame's rotation by using a sliding column.
[0021] Furthermore, the protrusion is in close contact with the push plate;
[0022] The above technical solution allows the push plate to move easily by having the protrusions fit tightly against it.
[0023] This utility model has the following beneficial effects:
[0024] 1. This utility model proposes a hip-opening device for dance training. Compared with existing hip-opening devices for dance training, when this hip-opening device is used, the servo motor drives the rotating column to rotate, which in turn drives multiple sets of protrusions to move. They then continuously tap the push plate. At this time, the push plate is subjected to force, which drives the return spring to compress, thereby causing its massage block to extend. Through the interval of the protrusion rotation and the extension and contraction of the return spring, the massage block is driven to move back and forth, which helps to relax tense muscle fibers and maintain their elasticity and flexibility. When the hip-opening action stretches the muscles, the synergistic effect of the massage can prevent the muscles from being overstretched or torn.
[0025] 2. The hip-opening device for dance training proposed in this utility model, compared with the existing hip-opening devices for dance training, when in use, the servo motor drives the active rod to rotate, which in turn drives the transmission wheel and synchronous belt on one side to rotate. This, in turn, drives the driven rod and the active gear on the other side to rotate. The rotation of the active gear drives the driven gear and the rotating rod to rotate in the opposite direction, thereby driving the auxiliary frames on both sides to adjust the angle. It can continuously adjust the degree of hip opening as needed, and has high practical performance. Attached Figure Description

Multiple massage blocks 38 are fixedly connected to the outer wall on the other side of the push plate 37. The massage blocks 38 penetrate through the storage cavity 32 to the outside of the opposite side of the auxiliary frame 3.
[0037] Compared with existing hip-opening devices for dance training, this hip-opening device, when in use, drives the active rod 22 to rotate by starting the servo motor 21, which in turn drives the transmission wheel 24 and synchronous belt 25 on one side to rotate. This, in turn, drives the driven rod 23 and the active gear 27 on the other side to rotate. The rotation of the active gear 27 drives the driven gear 28 and the rotating rod 26 to rotate in the opposite direction, thereby driving the auxiliary frames 3 on both sides to adjust their angles. It can continuously adjust the degree of hip opening as needed, and has high practical performance.
[0038] A backrest 11 is fixedly connected to the rear end of the upper surface of the base 1. A first connecting strap 12 and a second connecting strap 14 are fixedly connected to the lower parts of both sides of the outer wall of the backrest 11. Fasteners 13 and buckle bodies 15 are fixedly connected to the outer walls of adjacent sides of the first connecting strap 12 and the second connecting strap 14, respectively. The backrest 11 provides back support for the user during hip-opening exercises, enabling the user to maintain a correct sitting posture and preventing them from falling backward due to loss of balance during training. Fasteners 13 and buckle bodies 15 engage in a snap-fit connection, allowing the user's body to be further secured to the backrest 11. A PLC control panel 17 is embedded in the middle of the upper surface of the base 1. 7 is electrically connected to servo motor 1 21 and servo motor 2 33 respectively. The switch can be easily controlled through the PLC control panel 17. The driving gear 27 and driven gear 28 mesh with each other. The meshing of the driving gear 27 and driven gear 28 facilitates the reverse rotation of driven rod 23 and rotating rod 26.

The sliding column 31 facilitates the fit. The sliding column 31 is slidably connected to the inner wall of the slide groove 16. The sliding column 31 facilitates the stability of the rotation of the auxiliary frame 3. The protrusion 35 is tightly fitted with the push plate 37. The tight fit between the protrusion 35 and the push plate 37 facilitates the movement of the push plate 37.
[0039] Working principle: During use, the user's back is pressed against the backrest 11, and the user's body is further secured by the fasteners 13 and 15. The legs are pressed against the massage blocks 38 on both sides. The servo motor 21 is activated, driving the drive lever 22 to rotate, which in turn drives the transmission wheel 24 and synchronous belt 25 on one side. This, in turn, drives the driven lever 23 and drive gear 27 on the other side to rotate. The rotation of the drive gear 27 drives the driven gear 28 and rotating rod 26 to rotate in the opposite direction, thereby adjusting the angle of the auxiliary frames 3 on both sides. The degree of hip opening needs to be continuously adjusted. Then, by starting the servo motor 33, the rotating column 34 is rotated, which in turn drives multiple sets of protrusions 35 to move. This continuously taps the push plate 37. At this time, the push plate 37 is subjected to force, which drives the return spring 36 to compress, thereby causing its massage block 38 to extend. Through the interval of the rotation of the protrusion 35 and the extension and retraction of the return spring 36, the massage block 38 is driven to move back and forth, which can help relax tense muscle fibers and maintain their good elasticity and flexibility. When the hip opening movement stretches the muscles, the synergistic effect of the massage can prevent the muscles from being overstretched or torn.
