Specific embodiment

With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail, it is to be understood that this is practical Novel protection scope is not limited by the specific implementation.

Waist device under a kind of dance training, it is specific as shown in Figs 1-4, including load-bearing bases 1, fixation is set on load-bearing bases 1 It is equipped with the first column 2 and the second column 3, waist contact cylinder 4, the first column 2 are connected between the first column 2 and the second column 3 Be provided with vertical sliding slot 21 on the second column 3, the both ends of waist contact cylinder 4 are connected separately with sliding shoe 41, sliding shoe 41 are slidably connected with the one-to-one correspondence of sliding slot 21；

Power Component for sliding up and down waist contact cylinder 4 is installed, Power Component includes upper end on the first column 2 Fixed pulley 5, lower end fixed pulley 6, connecting rope 7, ceiling board 22 and the stretchable elastomeric element 8 of length；On load-bearing bases 1, it is located at Upper end fixed pulley 5 is installed at the upper end of first column 2, lower end fixed pulley 6 is installed at the lower end of the first column 2, on End fixed pulley 5 is wrapped with the shared connecting rope 7 of a two on lower end fixed pulley 6, connecting rope 7 can along upper end fixed pulley 5, under It holds fixed pulley 6 to move back and forth, is fixedly installed with wrapping post 411 on the sliding shoe 41 connecting with the sliding slot 21 on the first column 2, even Splicing 7 is also fixed to be tied up on wrapping post 411, and the end of connecting rope 7 is that fixation ties up on wrapping post 411, the first column 2 The upper end equipped with sliding slot 21, ceiling board 22, one end of elastomeric element 8 and ceiling board are fixedly installed with above sliding slot 21 22 are fixedly connected, and the other end is fixedly connected with sliding shoe 41, between elastomeric element 8 and the first column 2 there are 0.5-2cm away from From preventing elastomeric element 8 from rubbing when stretching the first column 2.

It should be noted that waist contact the distance between cylinder 4 and load-bearing bases 1 exist when elastomeric element 8 stretches naturally 40-120cm, when elastomeric element 8 is in maximum extension state, waist contacts the distance between cylinder 4 and load-bearing bases 1 in 30- 100cm, the maximum deformation of length amount of elastomeric element 8 are 10-20cm.This is apart from applicable to children and adult.

In the embodiments of the present invention, load-bearing bases 1 are used to bear the weight of all components and human body, and waist connects Touching cylinder 4 provides supporting point and support force for directly contacting with human body waist；First column 2 and the second column 3 and sliding slot 21 are Waist contact cylinder 4 provides sliding basis, and the top and bottom of sliding slot 21 carry stopper, sliding shoe 41 is prevented to be sliding out sliding slot 21.The working principle of the utility model is as follows, if the lower waist level of trainer is not high, when trainer carries out the training of lower waist, most Being easy waist location reduces, and otherwise will feel uncomfortable, there is pain sensation, at this moment by trainer back or waist and waist Contact cylinder 4 directly contacts, and elastomeric element 8 pulls up waist contact cylinder 4, when trainer's waist location gradually decreases, elasticity Component 8 stretches, and waist contacts cylinder 4 and glides, and declines slot milling to trainer's waist location, reduces the discomfort generated when training Sense, when elastomeric element 8 reaches the largest deformation amount of its permission, waist contact cylinder 4 stops gliding, and directly serves as supporting role, It is bent and uses for trainer's waist.If it is intended to deconditioning, stands up, waist contacts cylinder 4 in the restoring force of elastomeric element 8 at this time Effect is lower to be resetted.If the lower waist level of trainer is higher, waist location decline is less during lower waist, or even does not decline.It can To contact the amplitude that cylinder 4 glides by waist come the lower waist level of training of judgement person, teacher is given to provide reference, teacher can be according to feelings Condition carries out personalized training to different people.

The fixation of connecting rope 7 ties up on wrapping post 411, and waist contact cylinder 4, which moves up and down, forces wrapping post 411 to move up and down, And then connecting rope 7 is driven to move back and forth, using the pulley action of upper end fixed pulley 5, lower end fixed pulley 6, same root connecting rope 7 can It uses always, does not have to adjust its length.

Elastomeric element 8 is spring or stretch cord, and on ceiling board 22 and is mounted on fixed ring on sliding shoe 41, elasticity The end of component 8 can tie up to or hang in fixed ring, realize elastomeric element 8 it is detachable, be conveniently replaceable.

Waist contact cylinder 4 includes fixed link 42 and the rotating cylinder 43 being set in outside fixed link 42, the both ends point of fixed link 42 It is not fixedly connected with corresponding sliding shoe 41, rotating cylinder 43 is rotatably connected in fixed link 42 by bearing, and bearing is mounted on rotating cylinder Between 43 and fixed link 42.According to the speed and height of waist under trainer, the adaptive rotation of rotating cylinder 43 adjusts angle, and increase makes The comfort of user.

In fixed link 42, binding nut 421 is bolted at 43 two sides of rotating cylinder, two binding nuts 421 can rotate To being abutted with rotating cylinder 43, is clamped, limit its rotation, rotating cylinder 43 can not rotate at this time；Two binding nuts 421 can rotate To separating with rotating cylinder 43, rotating cylinder 43 is able to rotate at this time.Anti-slip cover, the existing anti-skidding left side of Anti-slip cover are socketed with outside waist contact cylinder 4 The right side, and have buffer function.Trainer is suitble to the apparatus structure training of oneself according to self-demand selection.

Load-bearing bases 1 include the first pedestal and the second pedestal, and the first pedestal is fixedly connected on 2 bottom of the first column, and second Pedestal is fixedly connected on 3 bottom of the second column.Threaded hole is offered on first pedestal and the second pedestal, for being inserted into fixed spiral shell Bolt is fixed on the ground the first pedestal and the second pedestal using fixing bolt, increases device stability.

The quantity of Power Component is two, one of them is mounted on the first column 2, another is mounted on the second column 3 On, the mounting means of Power Component is identical as the mounting means of Power Component on the first column 2 on the second column 3, vertical with second It is fixedly installed with anchor line (string) column on the sliding shoe 41 that sliding slot 21 on column 3 connects, the connecting rope on the second column 3 on Power Component is solid Surely it ties up on anchor line (string) column.

It should be noted that repeating in order to prevent, the utility model describes preferred embodiment.Although this has been described The preferred embodiment of utility model, once a person skilled in the art knows basic creative concepts, then can be to these Embodiment makes other change and modification.So the following claims are intended to be interpreted as including preferred embodiment and falls into All change and modification of the scope of the utility model.

Obviously, it is practical without departing from this can to carry out various modification and variations to the utility model by those skilled in the art Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and Within the scope of its equivalent technologies, then the utility model is also intended to include these modifications and variations.
