Abstract
A three-shaft synchronously rotary mechanism for a body-building waist twisting machine relates to a fitness instrument and has the advantages of convenient use and reliable action. The three-shaft synchronously rotary mechanism comprises a frame, a motor, a power transmission mechanism, a drive shaft, a drive crank, a driven shaft, a driven crank and a rotary base plate, wherein the motor is mounted on the frame and is connected with the drive shaft through the power transmission mechanism; the body of the drive shaft is rotationally mounted on the frame through a bearing; one end of the drive crank is connected at the upper end of the drive shaft while the other end thereof is rotationally connected to the rotary base plate; the body of the driven shaft is rotationally mounted on the frame through a bearing; the upper end of the driven shaft is connected with one end of the driven crank; the other end of the driven crank is rotationally connected to the rotary base plate; and an output shaft of the motor, the drive shaft and the driven shaft realize three-shaft synchronous rotation. With the three-shaft synchronously rotary mechanism, the waist of an exerciser can be twisted, and the safety property of the mechanism is good.
Description
Technical field
The utility model relates to a kind of body-building apparatus and health and fitness facilities, especially relates to a kind of three synchronous rotating mechanisms that are used for the body-building waist-twisting machine.
Background technology
Under the overall background of social progress and productivity development, the diversification more that becomes of people's demand.The quickening of modern's rhythm of life reaches the further requirement to leisure sports goods and health product demand, people are to the continuous lifting of healthy pay attention to day by day and living standard, make the use of health equipment and health and fitness facilities increasingly extensive, people are also more and more to the functional requirement of health equipment and health and fitness facilities, except requiring its function, also wish to have other functions such as physiotherapy, massage and fitness with exercise limbs.The demand of the product that broad masses of the people's demand is body-building and entertaining integrated is more strong.
Along with society pushes ahead, clerical workforce and white collar personnel amount are increased sharply rapidly, and they are in the face of the huge social operating pressure.Because for a long time office and office building work, at present, the problematic people of lumbar spine is more and more, and people urgently wish to have and both had the function of tempering limbs, can also revise and the fitness equipment of function such as fitness lumbar spine simultaneously.
So series of products such as body-building waist-twisting machine are just given birth at once.Existing body-building waist-twisting machine mostly is made of frame, handrail and rotating disk, rotating disk is rotatably installed on the frame, the person taking exercise stands on the rotating disk, hand steered handrail, reach counterclockwise rotation twisting clockwise by the own waist of sporter, the rotation of realization single shaft, thus reach the purpose of reversing waist, can reach the purpose of enure waist to a certain extent.
Present waist-twisting machine will can perform physical exercise by person taking exercise's self twisting, uses inconvenient.And the health of oneself meeting rotation has limited the user so greatly waist-twisting machine has been forged the enthusiasm of experienced mode and the effect of use like this.Thereby limit popularizing of waist-twisting machine greatly.
Present waist-twisting machine mostly appears at open airs such as park, residential quarter, physical culture place in the mode of workout path.Like this, not only can be subjected to the influence of restriction of very big run duration and weather conditions, and because the factor of single shaft rotation can be brought contingent to a certain extent athletic injury to the sporter under the situation improperly moving.
Summary of the invention
The purpose of this utility model is to provide three synchronous rotating mechanisms of body-building waist-twisting machine of a kind of easy to use, reliable in action.
The utility model is provided with frame, motor, power drive mechanism, driving shaft, driving crank, driven shaft, driven crank and rotary plate.
Motor is installed on the frame, motor connects driving shaft by power drive mechanism, the body of described driving shaft is rotatably installed on the frame by bearing, and the driving shaft upper end connects an end of driving crank, and the other end of driving crank rotatably is connected on the rotary plate; The body of driven shaft is rotatably installed on the frame by bearing, and the upper end of driven shaft connects an end of driven crank, and the other end of driven crank rotatably is connected on the rotary plate, and motor output shaft, driving shaft and driven shaft are realized three rotations synchronously.
Described power drive mechanism can be provided with drive pulley, belt and driven pulley; Drive pulley is set on the motor output shaft, and driven pulley is socketed in the lower end of driving shaft, and belt is connected across between drive pulley and the driven pulley.
The body of described driving shaft is rotatably installed on the frame by bearing, and preferably the body of driving shaft is rotatably installed on the frame by thrust ball bearing and deep groove ball bearing.
The body of described driven shaft is rotatably installed on the frame by bearing, and preferably the driving shaft upper end connects an end of driving crank, and the other end of driving crank is by thrust ball bearing and the rotatable support rotary plate of deep groove ball bearing.
Described driven shaft can be provided with two, and the body of these two driven shafts is rotatably installed on the frame by thrust ball bearing and deep groove ball bearing; The upper end of driven shaft connects an end of driven crank, and the other end of driven crank rotatably supports rotary plate by thrust ball bearing and deep groove ball bearing.Driving shaft and two driven shafts are equilateral triangle and are arranged on the frame.
Compare with existing body-building waist-twisting machine, the utlity model has following outstanding advantage: because motor is by driving shaft and driving crank driven rotary substrate rotating, make motor output shaft, driving shaft and three rotations synchronously of driven shaft, can realize three stressed in the same way and stressed sharing equally in machine driving and the mechanical analysis for three, therefore need not the twisting of person taking exercise's waist, just can reach the purpose of twisting person taking exercise waist, very convenient to use.Because the utility model adopts simple pulley transmission mechanism and frame for movements such as power transmission shaft and crank, therefore to move reliable and stablely, security is better.In addition, by Single-chip Controlling, can realize speed and both forward and reverse directions that rotary plate rotates as motor.
