A dance flexibility device

Abstract

The present invention relates to the technical field of dance flexibility training, in particular to a dance flexibility device, comprising a base, a motor is fixedly connected to the inside of the drive box, a gear 1 is fixedly connected to the output end of the motor, and a gear 1 is fixedly connected to the output end of the base. The bottom surface is fixedly connected with a leg expansion drive mechanism, and the leg expansion drive mechanism includes two support blocks, the top surfaces of the two support blocks are fixedly connected with the bottom surface of the base, and the two support blocks are rotatably connected with A threaded rod, one end of the threaded rod is socketed and fixed with a second gear, and the second gear is meshed with the first gear for transmission. In the present invention, the motor rotates with the threaded rod, and the two limit posts respectively move with the connecting rods at the corresponding positions, so that the two connecting rods are gradually unfolded with the leg resting frame, which is convenient for the trainer to perform flexible training of lateral leg splitting. It is necessary to control the steering of the motor to realize the reciprocating movement of the leg resting frame on the base, which is convenient for repeated practice of lateral splitting and improves the efficiency of lateral splitting training.

Description

technical field [0001] The invention relates to the technical field of dance flexibility training, in particular to a dance flexibility device. Background technique [0002] Dance flexibility mainly includes the flexibility of the legs and the flexibility of the waist. Splitting training is an indispensable item in leg flexibility training. Splitting is generally divided into horizontal splitting and vertical splitting. When practicing horizontal splitting, trainers Generally, you sit on the ground and gradually spread your legs horizontally. When your legs are stretched into a "one" shape, you can press your body forward again. However, the horizontal stretching of your legs and the downward pressure of your body generally require an accompanying trainer. A large amount of manpower is required to assist in the operation, which is time-consuming and labor-intensive and affects the efficiency of lateral split training. Moreover, when the accompanying trainers gradually move t...

[0002] Dance flexibility mainly includes the flexibility of the legs and the flexibility of the waist. Splitting training is an indispensable item in leg flexibility training. Splitting is generally divided into horizontal splitting and vertical splitting. When practicing horizontal splitting, trainers Generally, you sit on the ground and gradually spread your legs horizontally. When your legs are stretched into a "one" shape, you can press your body forward again. However, the horizontal stretching of your legs and the downward pressure of your body generally require an accompanying trainer. A large amount of manpower is required to assist in the operation, which is time-consuming and labor-intensive and affects the efficiency of lateral split training. Moreover, when the accompanying trainers gradually move the trainer's legs away, sometimes the trainer's leg is strained due to excessive force. Scholars sometimes perform vertical splits, and generally sit on a yoga ball and gradually spread their legs vertically for training. However, traditional dance flexibility training devices generally can only perform one type of flexibility training, and cannot combine multiple dance flexibility exercises. Flexible training programs combined together, thus affecting the effect of dance flexibility training
