Abstract

The utility model discloses an improved structure of a waist turning machine, which comprises armrests, a rack serving as a slide rail, and two treadle mechanisms for swinging; the armrests are vertically and fixedly connected at the middle part of the rack, and the two treadle mechanisms are respectively connected on the slide rail of the rack in sliding way; each treadle mechanism mainly comprises a foot treadle, a swinging rack, a limit seat and a sliding support; and the swinging rack is matched with a fan groove of the limit seat through a limit pin shaft on the revolving shaft for performing swinging angle limit. Because the limit pin shaft penetrating through the revolving shaft of the swinging rack is utilized to limit the swinging angle of each treadle mechanism, the limit pin shaft is in rigid combination with the revolving shaft of the swinging rack, the rigidity is rather strong, and both the limit pin shaft and the limit seat containing the limit pin shaft are metal pieces, the utility model has rather good hardness and wear resistance properties, is not easy to break, and has long service life.

Description

The improvement structure of waist-twisting machine

Technical field

The utility model relates to a kind of body-building apparatus, particularly relates to a kind of improvement structure of waist-twisting machine.

Background technology

Along with rapid economy development, people are to the continuous lifting of healthy pay attention to day by day and living standard, make the use of health equipment increasingly extensive, people are also more and more to the functional requirement of health equipment, except requiring it to have the function of tempering limbs, also wish to have other functions such as physiotherapy, massage, fitness.Rapid surge along with clerical workforce and white collar personnel number, and in the face of the huge social operating pressure, the problematic people of lumbar spine is more and more, can also revise and function such as fitness lumbar spine when people urgently wish to have a kind of fitness equipment to have the limbs of exercise.So waist-twisting machine is just given birth at once.Commonly use waist-twisting machine and generally be made of frame, handrail and rotating disk, rotating disk is rotatable to be installed on the frame, and the person taking exercise stands on the rotating disk, and hand steered handrail by the swing of own waist, reaches the purpose of reversing waist.The rotating disk of this waist-twisting machine mostly only is one, and the person taking exercise needs both feet to stand on it, can not laterally slide, and the pattern of exercise is comparatively single.

The utility model content

The purpose of this utility model is to provide a kind of and is not easy to damage, long service life, can limit the improvement structure of the waist-twisting machine of pendulum angle preferably.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of improvement structure of waist-twisting machine, and it comprises handrail, the frame as slide rail, two footstep mechanisms that are used to swing; Described handrail vertically is fixed in the middle part of frame, and two foot-operated mechanisms slip respectively on the slide rail of frame; Described footstep mechanism mainly is made up of pedal, swing span, limit base, travelling carriage; Described swing span is made of with the vertical rotating shaft that is fixed in the cross bar bottom surface cross bar, radially wears a spacing bearing pin in rotating shaft, and the two ends of this spacing bearing pin all pass the circumferential surface of rotating shaft; Described pedal is fixed on the end face of swing span cross bar; Four jiaos of described travelling carriage are provided with the pulley that slips with the frame slide rail, and limit base is fixed on the central authorities of travelling carriage; The middle part of described limit base has an axis hole that supplies swing span rotating shaft activity to penetrate, the upper, open end of this axis hole radially, symmetry expands outwardly out two fan grooves, the section of passing that described swing span rotating shaft activity penetrates the spacing bearing pin in axis hole and the rotating shaft can abut against fan groove in, the pendulum angle of spacing bearing pin is limited by the sidewall of fan groove.

After adopting such scheme, because the spacing bearing pin restrict foot that the utility model utilization is arranged in the swing span rotating shaft is stepped on the pendulum angle of mechanism, this spacing bearing pin combines with swing span rotating shaft rigidity, has stronger rigidity, the limit base of spacing bearing pin and ccontaining spacing bearing pin is all metalwork, have better hardness and wearability, be not easy to damage long service life.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 2 is the three-dimensional exploded view of the utility model footstep mechanism;

Fig. 3 is the installation diagram after the utility model footstep mechanism removes pedal;

Fig. 4 is the three-dimensional exploded view after the utility model footstep mechanism removes pedal;

The specific embodiment

As shown in Figure 1, the utility model is a kind of improvement structure of waist-twisting machine, and it comprises handrail 1, the frame 2 as slide rail, two footstep mechanisms that are used to swing 3.

Described handrail 1 vertically is fixed in the middle part of frame 2, and two foot-operated mechanisms 3 slip respectively on the slide rail 21 of frame 2.

As Fig. 2, shown in Figure 4, described footstep mechanism 3 mainly is made up of pedal 31, swing span 32, limit base 33, travelling carriage 34, pulley 35.Rotating shaft 322, spacing bearing pin 323 that described swing span 32 by cross bar 321, vertically is fixed in cross bar 321 bottom surfaces constitute; Radially wear a spacing bearing pin 323 in rotating shaft 322, the two ends of this spacing bearing pin 323 all pass the circumferential surface of rotating shaft 322; Described pedal 31 is fixed on the end face of swing span 32 cross bars 321; Four jiaos of described travelling carriage 34 are provided with the pulley 35 that slips with frame 2 slide rails 21, and limit base 33 is fixed on the central authorities of travelling carriage 34; The middle part of described limit base 33 has an axis hole 331 that penetrates for swing span 32 rotating shafts 322 activities, the upper, open end of this axis hole 331 radially, symmetry expands outwardly out two fan grooves 332.

Operation principle of the present utility model:

As Fig. 3, shown in Figure 5, when described swing span 32 rotating shafts 322 activities penetrated in the axis hole 331, the section of passing of the spacing bearing pin 323 in the rotating shaft 322 can abut against the bottom surface of limit base 33 fan grooves 332 and add gravity and all drop on the contact-making surface of spacing bearing pin 323 and fan groove 332.During swing span 32 swings, spacing bearing pin 323 swings back and forth in fan groove 332, and the pendulum angle of spacing bearing pin 323 is limited by the sidewall of fan groove 332, thereby has limited the pendulum angle of swing span 32 swings.

Emphasis of the present utility model just is: the pendulum angle of footstep mechanism cooperates with the fan groove of limit base by the spacing bearing pin in the rotating shaft and carries out pendulum angle restriction.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
