Description
Technical Field
The invention relates to a dance training apparatus, in particular to a dance training back leg opening degree lifting auxiliary device.
Background
The 'opening, tightening and straightening' is a basic requirement for dancers, plays a central role in a dance basic training system, and is also an important aesthetic standard for industry evaluation. In dance training, especially in ballet basic training and classical Chinese dance basic training, the basic actions of horizontal forks, vertical forks and the like to the typical actions of Arabeque, Attitude, inverted kicking of purple golden crowns and the like all need the support of the soft opening degree of the back leg part. Since this training relates to the thigh flexor group (quadriceps femoris, tensor fasciae latae, pubic muscle), the thigh extensor group (biceps femoris, semitendinosus, semimembranosus, adductor major) and the hip joint, knee joint, etc., training for the specification of the opening degree of the soft back leg becomes one of the important subjects in the field of dance education.
The most typical and difficult "bow step" state action of controlling in the daily training of back leg, in the training teaching of conventionality, adopt "gluteus maximus position external force forced compression method" and "bow step independently press the method" cooperation training mostly, produced certain training effect, but the drawback is also comparatively prominent:
1. in the external force pressing method for the gluteus maximus part, the front leg of a pressed person keeps a bow step state, the back leg extends in the vertical backward direction, the knee and the instep are tightly attached to the ground, and a professional dance teacher uses hands, feet and the like to strongly press the gluteus maximus part of the back leg of the pressed person or holds the pressed person tightly and squats to sit on the gluteus maximus part of the pressed person by means of teaching experience. Due to the problems of teachers' manipulation, experience, force controllability and the like, the injury of muscles and fascia of a pressed person is very easy to occur, and even the case of skeletal injury occurs.
2. In the "bow step autonomous compression method", the trainee keeps the bow step state, and pulls down by gravity according to the breathing shivering down or keeping the body upright. The body core and the knee joint need to be kept stable during the training process, and the sense of relaxation and gravity center sinking of the hip joint are always kept. For dancers with weak training foundation, insufficient training strength and weak dance muscle control ability, good training results are difficult to obtain, even irregular motions or methods such as 'knee joint cannot stretch straight and extend' and 'knee joint pronation' often occur, and a lot of risks are brought to training.
Disclosure of Invention
In view of the above-mentioned drawbacks of the prior art, the present invention is directed to provide a device for assisting in the opening-lifting of the soft back leg of a dancer, which is used for assisting in the training of the soft back leg of the dancer with a weak training base and a weak dancing muscle control ability.
The technical scheme of the invention is as follows: the utility model provides a soft aperture of leg promotes assistor after dance training, includes base, pull rod, leg hoop and knee-pad layer board arrange in proper order from beginning to end set up in on the base, the pull rod pass through the pull rod cable connect in the base, the leg hoop pass through the lift bracing piece connect in the base, the pull rod with the leg hoop for the synchronous reverse lift of base, the knee-pad layer board pass through elastic support rod connect in the base.

Detailed Description
The present invention is further illustrated by the following examples, which are not to be construed as limiting the invention thereto.
Referring to fig. 1 to 3, the leg-opening-degree-lifting assistor for dance training according to the present embodiment includes a base 1, a pull rod 2, a leg hoop 3, and a knee pad support plate 4, wherein the pull rod 2, the leg hoop 3, and the knee pad support plate 4 are sequentially arranged on the base 1 in a front-to-back manner. The front part of the base 1 is provided with a pull rod 2, the middle part is provided with a leg hoop 3, the rear part is provided with a knee pad supporting plate 4, the leg hoop 3 is connected on the base 1 through a lifting supporting rod 5, and the knee pad supporting plate 4 is connected on the base through an elastic supporting rod 6.
Specifically, a through hole is opened in the front of base 1, pull rod 2 is connected with pull rod cable 7, and pull rod 2 is connected to the head end of pull rod cable 7, and the tail end of pull rod cable 7 stretches into the inside of base 1 from the through hole of front portion. A through hole is also formed in the middle of the base 1, the leg hoop 3 is an annular hoop with an open upper end, the lower end of the leg hoop 3 is connected with the lifting support rod 5, the lifting support rod 5 comprises a leg hoop spring 5a, and a flexible protective sleeve 5b can be arranged outside the leg hoop spring 5a to prevent the leg hoop spring 5a from being exposed. The bottom end of the leg hoop spring 5a is fixedly connected to the chassis 1, the through hole in the middle of the chassis 1 is positioned below the leg hoop spring 5a, and the top end of the leg hoop spring 5a is fixedly connected with the leg hoop 3. The lower end of the leg hoop 3 is also connected with a leg hoop guy cable 8, the leg hoop guy cable 8 is arranged in the leg hoop spring 5a, and the tail end of the leg hoop guy cable extends into the base 1 through a through hole in the middle of the base 1. A gear rack group is arranged in the base 1 and comprises a pull rod rack 9 and a leg hoop rack 10, one end of the pull rod rack 9 is connected with a pull rod inhaul cable 7, one end of the leg hoop rack 10 is connected with a leg hoop inhaul cable 8, and the pull rod rack 9 and the leg hoop rack 10 are meshed with each other through two groups of gears and a middle rack 11 to transfer force. As shown in fig. 3, when the pull rod rack 9 is pulled by the pull rod cable 7 (the pull rod 2 is pulled upwards) to move leftward, the first gear 12 and the fourth gear 15 rotate clockwise, the second gear 13, the third gear 14 and the fifth gear 16 rotate counterclockwise, the middle rack 11 also moves leftward, the leg hoop rack 10 moves rightward, and the leg hoop cable 8 further extends into the chassis 1, so that the leg hoop 3 descends. The lifting ratio of the pull rod 2 to the leg hoop 3 is 1: 1.5-1: 2, namely, when the pull rod 2 rises by 1cm, the leg hoop 3 descends by 1.5-2 cm, the lifting movement range of the pull rod 2 relative to the base 1 is 15-20 cm, namely, the lifting movement range of the leg hoop 3 relative to the base 1 is 30-40 cm. The internal structure of the base 1 mainly aims at realizing the reverse motion of the pull rod 2 and the leg hoop 3, so that a similar effect can be achieved through a pulley block besides the rack and pinion group, the lifting ratio of the pull rod 2 and the leg hoop 3 can be adjusted through the gear size ratio by adopting the rack and pinion group, and the lifting ratio of 1: 2 can be realized through a movable pulley by using the pulley block.
