Technical Field
[0001] This invention relates to the field of training devices, and more specifically to a dance flexibility training device. Background Technology
[0002] Flexibility is an important prerequisite for mastering dance skills. This flexibility is manifested in suppleness, which is the foundation of dance. In the daily training of dance students, flexibility training needs to adopt scientific training methods. Dancers with better flexibility can coordinate their bodies more easily and complete difficult movements more easily, thus achieving better stage effects. Flexibility not only affects dance technique but also limits the power, speed, and body coordination in dance. Insufficient flexibility can even cause muscle damage. Therefore, flexibility training is very important.
[0003] A Chinese patent publication number (CN218793773U) discloses a multifunctional dance flexibility training teaching device, including a base plate; an adjustment seat is fixedly connected to one end of the base plate; a screw is threadedly rotatably connected to the middle of the adjustment seat; and adjustment components are slidably connected to both sides of the adjustment seat. By setting the screw, the dancer sits on the seat and rotates the turntable, which drives the screw to screw into one side of the adjustment seat. Due to the threaded engagement, the hinge seat and connecting plate, which are connected to and fixed to the screw, move together towards one side of the adjustment seat. The dancer's feet are positioned at the limiting plate. Therefore, as the movable plate gradually changes from being inclined to the adjustment seat to being parallel to the adjustment seat, the two sets of support plates can move outwards respectively, thus simulating the effect of sitting and stretching. Moreover, the screw rotation is determined by the dancer himself, which has a certain degree of initiative and avoids the need for assistance from others, thus providing convenience.
[0004] The above-mentioned training device also has the following problems when used: the training device requires the dancer to manually rotate the turntable many times to carry out the training, which is inconvenient to operate. In addition, the device is only suitable for leg stretching of one dancer, which makes the applicability of the training device low.
[0005] Therefore, it is necessary to invent a dance flexibility training device to solve the above problems. Summary of the Invention
[0006] The purpose of this invention is to provide a dance flexibility training device to solve the problems mentioned in the background art, which require dancers to manually rotate a turntable multiple times during use, making the operation inconvenient, and the device is only suitable for leg stretching of one dancer, thus resulting in low applicability of the training device.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a dance flexibility training device, comprising a frame body, with legs fixedly connected to the bottom of the frame body to raise the entire training device to a certain height, thereby also training the dancer's balance; uprights fixedly connected to the outside of the legs, with crossbars movably installed inside the uprights; a motor fixedly connected to the bottom wall of the frame body, with the motor's output shaft drivingly connected to a drive shaft; a cavity reserved inside the frame body, with the drive shaft extending into the cavity; the upper end of the drive shaft rotatably connected to the top wall of the cavity via a bearing; and further comprising:
[0008] The adjustment component has a groove reserved inside the upright, and the crossbar moves inside the groove. The end of the crossbar is limited to the upright by a plug rod, which makes it easy to adjust the height of the crossbar and facilitates the dancer's leg stretching training.
[0009] The divergent stretching assembly has a gear fixedly sleeved on the outer wall of the drive shaft, and the gear meshes with the gear plate. The gear plate is fixedly connected to the moving block. A short column is fixedly connected to the top wall of the moving block, and the short column is fixedly connected to the pedal. The pedal slides against the top wall of the frame body. The divergent movement of the pedal stretches the dancer's legs. The training is convenient because it is driven by a motor.
[0010] The stable moving component has a limiting plate fixedly connected to the outer wall of the toothed plate, and the limiting plate moves within a limiting groove one reserved inside the frame body. The moving block has a notch reserved inside, and a square rod is fixedly connected inside the notch. The square rod matches the limiting groove two reserved inside the toothed plate to ensure the stable movement of the toothed plate.
[0011] Preferably, the two ends of the crossbar are provided with protrusions, the crossbar is in the shape of "I", and the outer walls of the two ends of the crossbar are attached to the inner wall of the reserved sliding groove inside the upright and are slidably connected up and down, so as to adjust the height of the crossbar up and down, so as to facilitate the dancer to perform leg pressing training.
[0012] Preferably, the insert rod matches the pre-reserved square groove inside the upright, and the square groove is connected to the sliding groove. Furthermore, there are three square grooves arranged in a linear pattern at equal intervals inside each upright, which allows for three selections of the height position of the crossbar, making it convenient to limit the crossbar at different height positions through the insert rod later.
[0013] The insertion rod end matches the pre-reserved open-shaped fitting groove in the end of the crossbar. The insertion rod is passed through the square groove and matched with the pre-reserved fitting groove in the end of the crossbar to limit the height position of the crossbar.
[0014] Preferably, there are two toothed plates, which are arranged in a staggered parallel manner. The different ends of the two toothed plates are fixedly connected to two moving blocks. During the rotation of the gear, the two sets of toothed plates are driven to perform staggered back-to-back movements. This facilitates the back-to-back movements of the two moving blocks. The back-to-back movements of the moving blocks drive the two pedals to perform leg stretching movements.
[0015] Preferably, there are two movable blocks, and the two movable blocks are symmetrically arranged with reference to the central axis of the drive shaft. The outer walls of the two movable blocks are attached to and slidably connected to the inner wall of the cavity to ensure the stability of the movable blocks' movement. The two movable blocks are located on both sides of the gear. At the same time, during the rotation of the gear, the two sets of tooth plates drive the two sets of tooth plates to perform an alternating back-to-back movement, which facilitates the back-to-back movement of the two movable blocks.
[0016] Preferably, the short column moves within a pre-reserved channel inside the top plate of the frame body, and the outer wall of the short column is attached to and slidably connected with the inner wall of the channel. The channel is symmetrically arranged in two sections, both of which are connected to the cavity. In this way, the leg stretching exercise is performed by driving the two pedals to move through the moving block's divergent movement.
[0017] Preferably, there are two notches, which are located at different ends of the two moving blocks. Two toothed plates are inserted into each notch, and the outer wall of the toothed plate is attached to and slidably connected to the inner wall of the notch to ensure the stability of the toothed plate movement.
[0018] The technical effects and advantages provided by the present invention in the above technical solution are as follows:
[0019] 1. This invention uses a starting motor to drive the drive shaft to rotate. The gear fixedly sleeved on the outer ring of the drive shaft rotates and meshes with the gear plate, thereby driving two moving blocks fixedly connected to the gear plate to move in opposite directions. This facilitates stretching exercises for the dancer's legs while stepping on the pedal. At the same time, the dancer can place their hands on the crossbar to maintain their balance, and other dancers can also support their legs on the crossbar for stretching. In this way, the crossbar can also provide training for other dancers, increasing the number of people who can use the entire training device at the same time and increasing the applicability of the main body of the device.
[0020] 2. At the same time, after the square insert is pulled out, the height of the crossbar can be adjusted to meet the needs of users of different heights. The square groove reserved inside the upright is matched with the fitting groove reserved at the end of the crossbar to ensure the position of the crossbar is fixed. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0033] This invention provides, for example Figure 1-8The dance flexibility training device shown includes a frame body 1, with support legs 2 fixedly connected to the bottom of the frame body 1, raising the entire training device to a certain height, which can also train the dancer's balance. A vertical pole 3 is fixedly connected to the outside of the support legs 2, and a horizontal bar 4 is movably installed inside the vertical pole 3. A motor 7 is fixedly connected to the bottom wall of the frame body 1, and the output shaft of the motor 7 is driven by a drive shaft 8. A cavity 6 is reserved inside the frame body 1, and the drive shaft 8 extends into the cavity 6. The upper end of the drive shaft 8 is rotatably connected to the top wall of the cavity 6 via a bearing. The device also includes:
[0034] Adjustment component 5, the inside of the upright 3 has a reserved slide groove 51, the crossbar 4 moves inside the slide groove 51, and the end of the crossbar 4 is limited to the upright 3 by the insertion rod 53, which makes it easy to adjust the height position of the crossbar 4 and facilitates the dancer to perform leg pressing training.
[0035] The back-extension assembly 9 has a gear 91 fixedly mounted on the outer wall of the drive shaft 8, and the gear 91 meshes with the toothed plate 92. The toothed plate 92 is fixedly connected to the moving block 93. The top wall of the moving block 93 is fixedly connected to a short column 94, and the short column 94 is fixedly connected to the pedal 95. The pedal 95 slides against the top wall of the frame body 1. The back-extension movement of the pedal 95 stretches the dancer's legs. The training is convenient because it is driven by the motor 7.
[0036] The stable moving component 10 has a limiting plate 101 fixedly connected to the outer wall of the toothed plate 92, and the limiting plate 101 moves within the limiting groove 102 reserved inside the frame body 1. The moving block 93 has a notch 103 reserved inside, and a square rod 104 is fixedly connected inside the notch 103. The square rod 104 matches the limiting groove 105 reserved inside the toothed plate 92 to ensure the stable movement of the toothed plate 92.
[0037] The two ends of the horizontal bar 4 are provided with protrusions. The horizontal bar 4 is in the shape of "I". The outer walls of the two ends of the horizontal bar 4 are attached to the inner wall of the groove 51 reserved inside the vertical bar 3 and are connected to slide up and down, so as to adjust the height of the horizontal bar 4 up and down, so as to facilitate the dancer to perform leg pressing training.
[0038] The insertion rod 53 matches the square groove 52 reserved inside the upright 3, and the square groove 52 is connected to the sliding groove 51. The square groove 52 is provided in three places in a linear and equally spaced manner inside each upright 3, so that the height position of the crossbar 4 can be selected in three positions, which makes it convenient to limit the crossbar 4 at different height positions through the insertion rod 53.
[0039] The end of the insert rod 53 matches the pre-reserved open-shaped fitting groove 54 in the end of the crossbar 4. The insertion rod 53 is passed through the square groove 52 and matched with the pre-reserved fitting groove 54 in the end of the crossbar 4 to limit the height position of the crossbar 4.
[0040] There are two toothed plates 92, which are arranged in a staggered parallel manner. The different ends of the two toothed plates 92 are fixedly connected to two moving blocks 93. When the gear 91 rotates, it drives the two sets of toothed plates 92 to perform staggered back-to-back movements. This facilitates the back-to-back movements of the two moving blocks 93.

In this way, the two pedals 95 are driven to move by the moving block 93 to perform the leg stretching exercise.
[0043] There are two notches 103, and the two notches 103 are located at different ends of the two moving blocks 93. Two toothed plates 92 are inserted and connected inside the two notches 103 respectively. The outer wall of the toothed plate 92 is attached to and slidably connected to the inner wall of the notch 103 to ensure the stability of the movement of the toothed plate 92.
[0044] Working principle: When using a dance flexibility training device, the dancer first stands on the foot pedal 95. Then, the motor 7 is started, which drives the drive shaft 8 connected to the output shaft of the motor 7 to rotate. The gear 91 fixedly sleeved on the outer ring of the drive shaft 8 rotates synchronously. During the rotation of the gear 91, the toothed plate 92 meshing with the gear 91 moves. The two toothed plates 92 achieve an alternating opposite movement, which in turn drives the two moving blocks 93 fixedly connected to the ends of the two toothed plates 92 to move in opposite directions. At this time, the foot pedal 95 is fixedly connected to the moving blocks 93 through the short column 94. The synchronous opposite movement of the two foot pedals 95 facilitates the stretching exercise of the dancer's legs on the foot pedal 95. At the same time, the dancer can place their hands on the horizontal bar 4 to maintain the balance of the body, thus ensuring safety during the training process.
[0045] Meanwhile, other dancers can also support their legs on the horizontal bar 4 for stretching exercises. In this way, the horizontal bar 4 can also provide training for other dancers, increasing the number of people who can use the entire training device at the same time, increasing the applicability of the main body of the device, and improving the applicability of the device.
[0046] Meanwhile, the height of the crossbar 4 can be adjusted. After the square insert 53 is pulled out, the height of the crossbar 4 can be adjusted. After the adjustment is completed, the insert 53 passes through the square groove 52 reserved inside the upright 3 and matches it with the fitting groove 54 reserved at the end of the crossbar 4 to ensure the position of the crossbar 4 is limited.
[0047] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
