The utility model belongs to the technical field of fitness equipment and particularly relates to a swing waist-twisting machine for exercising the waist by turning a human body. The swing waist-twisting machine comprises a base, a rotating disc installed on the base, and a foot board eccentrically installed on the rotating disc and capable of rotating relative to the rotating disc, wherein an outer connecting rod is arranged on the foot board, and the outer end of the outer connecting rod is hinged on a straightener capable of making rectilinear motion on the base; and the swing waist-twisting machine further comprises a power unit, wherein the power unit drives the rotating disc to rotate. The foot board is driven to rotate under the action of mechanical power, so that the swing waist-twisting machine is more convenient to use and more labor-saving; and the outer connecting rod is arranged on the foot board, the outer end of the outer connecting rod is hinged on the straightener capable of making rectilinear motion on the base, and the outer end of the outer connecting rod on the foot board always keeps rectilinear motion, so that the smooth reciprocating motion of the foot board can be ensured, the waist-twisting movement is more smooth, and the swing waist-twisting machine is more comfortable to use.

Wave waist-twisting machine

Technical field

The utility model relates to the body-building apparatus technical field, and is especially a kind of by reversing the body-building apparatus that the human body waist is performed physical exercise.

Background technology

Traditional body exercising machine that sways one's hips is divided into and rotates sitting posture and angled rotary two kinds fully, all has certain waist health-care function, but their motion only is to play waist twisting health care function, therefore function is comparatively dull, and rotate angle and position that the sitting posture body exercising machine will lean on people's health control twisting fully, use comparatively complicated; And the angled motion mode of the rotary body exercising machine of angle makes human body also have the rotation of a vertical direction outside rotating in the horizontal direction, and this physical training style not only can not make waist carry out complete twist motion, even also causes spraining of waist or ankle easily.

Have waving of No. the 200620160687.6th, Chinese patent subsequently and reverse body-building apparatus, it drives eccentric dial rotation by motor and drives foot-operated dish rotation, foot-operated dish exists pivotally connected with the chassis, it is affixed a connecting piece on the limited post on chassis, and also affixed a connecting piece on the foot-operated dish, form rotating pivotally connected between two braces, this structure can make the reciprocating motion of examining and seizing at an angle, reach the waist health-care function, also overcome simultaneously the sway one's hips weak point of body exercising machine of aforesaid tradition; But when reality is used, because the brace on chassis is connected the end relative fixed on the limited post, when riding dish work, the pivoting point of two braces can relative chassis brace be connected the biased pendulum of point on the limited post, can produce the high low level repeated stock of beat, even have the dead point, and cause foot-operated dish to rotate and have some setbacks, bring uncomfortable sensation to the user.

The applicant is because the fault of construction and the inconvenience of the above-mentioned known body exercising machine that sways one's hips, the spirit of adhering to the research innovation, keeping on improving, utilize professional eye and professional knowledge, at the fault of construction of the above-mentioned body exercising machine that sways one's hips and the problem of serviceability, propose a solution, therefore proposed the application of this case.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, provides a kind of and realizes waist exercise by waving rotation, and move smooth and easy, the comfortable waist-twisting machine that waves.

The utility model purpose again provides a kind of simple in structurely, scientific and reasonable, and that easily makes waves waist-twisting machine.

For achieving the above object, the utility model adopts following technical scheme:

Wave waist-twisting machine, have:

One base;

One is installed in the rolling disc on the base;

One off-centre is installed on the rolling disc and can relatively rotates the pedal that dish rotates, and pedal is provided with an outer connective pole, the outer end of outer connective pole be articulated in one can straight line moves on base rectifier;

One power unit drives the rolling disc motion.

Further design is on the basis of such scheme: be provided with the straight line chute on the base, and rectifier is provided with the slip pin, slip pin appearance is embedded in the straight line chute.

Such scheme further designs again: base is provided with two straight line chutes arranged side by side, and rectifier is provided with the slip pin that splits at two straight line chutes, and is provided with the cross-over connection connecting rod between the slip pin of two straight line chutes, the external rod hinge connection of cross-over connection connecting rod and pedal; Slip pin on the rectifier has rolling bearing.

In the such scheme, be belt transmission between described power unit and the rolling disc, comprise one or more levels belt transmission.

Be compared with the prior art, the utlity model has following beneficial effect:

1, drives the rotation of pedal by motor, therefore use more convenient laborsaving; In addition, because described pedal is a plane pedal, therefore when motion, pedal only can drive human body and horizontally rotate on horizontal plane, can not cause added burden to waist and ankle position.

2, pedal is provided with an outer connective pole, the outer end of outer connective pole be articulated in one can straight line moves on base rectifier, make that the connective pole external connection end remains rectilinear motion outside the pedal, the high low level of avoiding beat to bring impacts, guarantee the reciprocating motion that pedal can be smooth-going, the action that sways one's hips is more smooth, laborsaving, uses more comfortable.

3, simple in structure, scientific and reasonable, cost of investment is low, and the operation operation is easy, and Maintenance and Repair are very convenient, improved the operation ratio and the operability of waving waist-twisting machine greatly.
