Technical Field

The utility model belongs to the field of fitness equipment, and particularly relates to a pull-up power assisting device.

Background

Pull-up, sometimes called pull-up for short, refers to a hanging exercise that relies on self-strength to overcome self-weight to do work upwards. The training method mainly tests the development level of upper limb muscle strength, arm strength and waist and abdomen strength, needs a plurality of back skeletal muscles and upper limb skeletal muscles to jointly participate in work in the process of finishing a complete pull-up, is a multi-joint compound action exercise, is a better method for training upper limbs, and is a training mode which has the most muscle development, the most complex motion mode and the most effective muscle strength and muscle endurance of the back skeletal muscles in all training modes for developing the muscle strength and muscle endurance of the back skeletal muscles;

however, some novices are very labourious when beginning to pull up, and the existing pull-up auxiliary equipment has no power-assisted equipment, so that the existing auxiliary equipment is inconvenient to use when the novices practice. The auxiliary force of the existing power assisting equipment cannot be adjusted, and the existing power assisting equipment cannot achieve a good training effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems in the prior art and provides a pull-up power assisting device.

The purpose of the utility model can be realized by the following technical scheme: the utility model provides a chin booster unit, includes training frame and waistband, training frame includes the horizontal pole, the waistband is connected with take-up device respectively through two connection ropes, the connection rope includes elasticity rope and rigidity rope, the both ends of horizontal pole are provided with the fixed pulley, the one end and the waistband of elasticity rope are connected, the fixed pulley is walked around and is connected with the rigidity rope to the other end of elasticity rope, take-up device includes winding shaft and drive arrangement, drive arrangement is used for the drive to wind the axle rotatory, the winding shaft is used for supplying rigidity rope to convolute, take-up device is provided with controlling means, controlling means is used for controlling drive arrangement drive winding shaft pivoted number of turns and direction, camera device with controlling means communication connection is installed to the horizontal pole, camera device is used for discerning the people's face.

The working principle of the utility model is as follows: before training, the control device firstly controls the driving device to drive the winding shaft to rotate, so that the winding shaft winds the rigid rope to the maximum number of turns. E.g. a maximum of 10 turns, the winding shaft is rotated so that the rigid cord is wound 10 turns on the winding shaft. The trainer stands on the ground to tie the waist on the waist, one end of the elastic rope is connected with the waist, the other end of the elastic rope is connected with the rigid rope after passing around the fixed pulley, at the moment, the connecting end of the elastic rope and the rigid rope is closest to the winding device, so the tensile force borne by the elastic rope is the largest, the auxiliary force of the elastic rope reacting on the trainer is also the largest, after the training is started, the trainer holds the cross rod by both hands, the pull-up is started, when the trainer pulls up to the position where the camera device can recognize the face of a person, the pull-up is completed for one time, the camera device recognizes the face of a person, the camera device sends information to the control device, the control device controls the winding shaft to rotate for one circle, so that the rigid rope releases one circle (namely, the rigid rope is wound for 9 circles from the original winding for 10 circles), at the moment, the distance between the connecting end of the elastic rope and the rigid rope and the winding device is increased, when the trainer moves downwards to the lowest end, because the distance that the link of elasticity rope and rigid rope becomes far away from take-up device, the pulling force that the elasticity rope received at this moment diminishes, and the elastic rope counteracts the auxiliary force that acts on the training person also diminishes, and when the training person carried out the pull-up of second time, more arm strength was required. Analogize with this, the training person continues to carry out the chin upwards, upwards along with the chin each time, the auxiliary force that receives diminishes gradually, needs more arm strength to 10 times chin is a set of, when carrying out the 10 th time chin, the rigidity rope twines 1 circle on the winding shaft, the auxiliary force that the training person received is minimum, accomplish 1 group training back, the training person can operate controlling means, controlling means control winding shaft gyration for the rigidity rope twines 10 circles on the winding shaft, the training person begins to carry out next group training. When a trainer uses the pull-up assisting device to perform a group of training, the upward assisting force of the pulled body is reduced from large to small, the required arm strength is increased from small to large, and the trainer can obtain good exercise after performing a plurality of groups of training. The auxiliary force of the utility model can be adjusted, and a better training effect can be achieved.
