Technical Field

[0001] This utility model relates to the field of balance and flexibility training technology in aerobics teaching, and in particular to a device for balance and flexibility training in aerobics teaching. Background Technology

[0002] Aerobics is a popular and widely enjoyed sport that combines gymnastics, dance, music, fitness, and entertainment. It incorporates many movements from disco, jazz, and breakdancing, including movements involving the upper and lower limbs, torso, head and neck, and feet, particularly hip movements. This adds vitality to aerobics and helps reduce fat accumulation in the hips and abdomen, while also improving coordination and flexibility. Flexibility training is essential before and after aerobics workouts, including exercises such as seated forward bends, splits, and leg stretches.

[0003] In existing technologies, training the flexibility of the splits requires two to three people to perform leg-bending exercises on the trainee, which is very troublesome. Therefore, there is a lack of an aerobics teaching balance and flexibility training device that can be controlled by a single person and has a safety mechanism. Utility Model Content

[0004] Therefore, it is necessary to provide a balance and flexibility training device for aerobics instruction to address the aforementioned technical issues.

[0005] To achieve the above objectives, this utility model provides a balance and flexibility training device for aerobics teaching, including a seat and a frame disposed on both sides of the seat. A turntable is rotatably connected to the frame, and an arc-shaped rack with the turntable as its center is installed inside the frame. A fixed frame is slidably engaged on the frame, and a gear shaft is rotatably connected to the bottom of the fixed frame. A gear is installed at the bottom of the gear shaft, and the gear meshes with the arc-shaped rack. The gear shaft and the turntable are connected by a chain transmission assembly. A ratchet is installed on the turntable, and a locking block is installed inside the frame, which cooperates with the ratchet. A connecting block is slidably engaged inside the frame, and a spring is installed on the connecting block. The output end of the spring is connected to the locking block. A second spring is installed inside the frame, and its output end is connected to the connecting block. A pressing block is slidably engaged on the frame, and the pressing block abuts against the connecting block.

[0006] Preferably, the frame is provided with an arc-shaped slot centered on the turntable, and an arc-shaped locking block is slidably engaged in the arc-shaped slot, with the top of the arc-shaped locking block connected to the fixed frame.

[0007] Preferably, rollers are rotatably connected to both ends of the bottom of the arc-shaped card block, and the rollers abut against the inner wall of the arc-shaped card groove.

[0008] Preferably, the fixing frame is equipped with a number of elastic cotton strips.

[0009] Preferably, both the pressing block and the connecting block are provided with chamfers.

[0010] Preferably, springs are installed on both sides of the lower pressure block, and the output end of the springs is connected to the frame.

[0011] Preferably, the seat has several mounting holes at the bottom, and the seat is connected to the frame by bolts.

[0012] Preferably, the turntable is provided with a hinge groove, and a rotating rod is hinged in the hinge groove.

[0013] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0014] The user drives the turntable to rotate, which in turn drives the gear shaft to rotate, so that the gear meshing with the arc rack can move the fixed frame. Ultimately, a single person can control the movement of the fixed frame to perform flexibility training for the legs.

[0015] The ratchet and locking block are designed to allow the turntable to rotate in only one direction during training. In case of danger, the user can press down the pressure block to disengage the locking block from the ratchet, thereby resetting the mounting bracket and providing protection.

[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] Please see Figures 1 to 5 This application provides an aerobics teaching balance and flexibility training device, including a seat 1 and a frame 2 disposed on both sides of the seat 1. A turntable 3 is rotatably connected to the frame 2. An arc-shaped rack 4 with the turntable 3 as the center is installed inside the frame 2. A fixed frame 5 is slidably engaged on the frame 2. A gear shaft 6 is rotatably connected to the bottom of the fixed frame 5. A gear 7 is installed at the bottom of the gear shaft 6. The gear 7 meshes with the arc-shaped rack 4. The gear shaft 6 and the turntable 3 are connected by a chain transmission assembly 8. A ratchet 9 is installed on the turntable 3. A locking block 10 is installed inside the frame 2. The locking block 10 is configured to cooperate with the ratchet 9. A connecting block 11 is slidably engaged inside the frame 2. A spring 12 is installed on the connecting block 11. The output end of the spring 12 is connected to the locking block 10. A spring 23 is installed inside the frame 2. The output end of the spring 23 is connected to the connecting block 11. A pressing block 14 is slidably engaged on the frame 2. The pressing block 14 abuts against the connecting block 11.

[0024] In this embodiment, the trainee sits on the seat 1 and places their legs on the fixed frames 5 on both sides of the frame 2. By rotating the turntable 3, it drives the gear shaft 6 to rotate through the chain drive assembly 8. The gear 7 at the bottom of the gear shaft 6 meshes with the arc-shaped rack 4, thereby driving the fixed frame 5 to rotate. When the turntable 3 rotates, the ratchet 9 on it abuts against the locking block 10, so that the turntable 3 can only rotate in one direction, allowing the fixed frame 5 to drive the legs to perform flexibility training. During use, the second spring 13 compresses the connecting block 11, and the first spring 12 on the connecting block 11 compresses the locking block 10, allowing the locking block 10 to work normally. When needed, the user can press the lowering block 14 on the frame 2, causing the lowering block 14 to move the connecting block 11 away from the locking block 10, thereby de-engaging the ratchet 9 and the locking block 10, allowing the turntable 3 to rotate in the opposite direction, thus protecting the user.

[0025] In some embodiments, in order to ensure that the fixed frame 5 can maintain a certain stability when it is driven to move by the gear shaft 6, an arc-shaped slot 15 with the turntable 3 as the center is provided in the frame 2, and an arc-shaped block 16 is slidably engaged in the arc-shaped slot 15, with the top of the arc-shaped block 16 connected to the fixed frame 5.

[0026] In some embodiments, to facilitate the sliding engagement of the arc-shaped locking block 16 within the arc-shaped locking groove 15, rollers 17 are rotatably connected to both ends of the bottom of the arc-shaped locking block 16, and the rollers 17 abut against the inner wall of the arc-shaped locking groove 15.

[0027] In some embodiments, in order to enable the fixing frame 5 to limit the user's legs, a plurality of elastic cotton strips 18 are installed on the fixing frame 5.

[0028] In some embodiments, to facilitate the movement of the connecting block 11 by pressing down on the pressing block 14, both the pressing block 14 and the connecting block 11 are provided with chamfers.

[0029] In some embodiments, to facilitate the reset of the pressure block 14 after it is pressed down, springs 19 are installed on both sides of the pressure block 14, and the output end of the springs 19 is connected to the frame 2.

[0030] In some embodiments, in order to facilitate control of the distance between the two side frames 2 and the seat 1, the bottom of the seat 1 is provided with a plurality of mounting holes 20, and the seat 1 and the frame 2 are connected by bolts 21.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
