Description

A kind of waist-twisting machine

Technical field:

The utility model relates to the outdoor activity product, especially a kind of waist-twisting machine.

Background technology:

Waist-twisting machine of the prior art, comprise base and rotation pedal, wherein, the base mid portion is provided with a guide post, the rotation pedal is slidably mounted in the guide post upper end, and a tension spring is coated on the guide post, between base and the rotation pedal two torsion bars that evenly are provided with around guide post is installed also, two torsion bars include and are fixed on the lower fixed seat on the base and are fixed on the upper fixed seat that rotates on the pedal, and the terminal of upper and lower holder all flexibly connects with a connecting rod.When the user tramples the rotation pedal, the effect that the rotation pedal is subjected to human body gravity moves down and the compressive tension spring along guide post, simultaneously, torsion bar also is subjected to downward pressure, connecting rod on it comes into play and forces upper fixed seat and rotation pedal to rotate around guide post, after the tension spring accumulation of energy, the rotation pedal moves under the effect of spring tension, simultaneously, torsion bar upper connecting rod pulling upper fixed seat and rotation pedal spinning reduction, the waist that stands in the user on the rotation pedal twists along with the reciprocal rotation of rotation pedal, finally reaches the purpose of tempering waist.But this waist-twisting machine also exists deficiency:

The first, on this waist-twisting machine, tension spring is a straight barrel type tension spring, and the shortcoming of straight tube spring is that suppressed range is less, elastic force relatively a little less than, thereby influenced the sway one's hips amplitude of people in the exercise process to a certain extent, train on is not good enough.

The second, the tension spring of this straight barrel type structure, little with the end diameter of base and rotation pedal junction, directly caused the smoothness of rotation pedal in lifting and rotary course not high, the guide post that weares and teares has easily shortened service life of this waist-twisting machine;

The 3rd, on this waist-twisting machine, tension spring two ends are directly replaced with base and rotation pedal, the rotation pedal can produce very big frictional force with tension spring is terminal when rotated, increased the rotation difficulty of rotation pedal, occur the slow even non-rotary problem of rotation easily, its serviceability is very unstable;

The 4th, on this waist-twisting machine, torsion bar is flexibly connected by the upper and lower holder of rigidity and connecting rod and forms, be in when the next at the rotation pedal, torsion bar but can not accumulation of energy to help rotation pedal spinning reduction, its unreasonable structure.

The utility model content:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of not only stable performance, long service life are provided, and waist-twisting machine rational in infrastructure, that train on is good.

A kind of waist-twisting machine that provides according to the utility model, comprise base, be located at the rotation pedal of base upside, the base mid portion is provided with a guide post, the outer spring assembly that is with on the guide post, the rotation pedal is slidably mounted in the guide post upper end, described spring assembly comprises two volute springs and connects the slide of two volute springs, wherein, the larger diameter end of two volute springs is connected with base and rotation pedal respectively, smaller diameter end is connected with the upper and lower end face of slide respectively, between base and the rotation pedal the some torsion bars that are provided with around guide post is installed also.

According to a kind of waist-twisting machine that the utility model provides, also have following attached technical characterictic:

Described torsion bar comprises a rigid column and the soft post of being located at these rigid column two ends, and two soft post one ends and rigid column are spirally connected, and the other end is spirally connected with base and rotation pedal respectively.

Described slide comprises the upper and lower plectane of overlapping setting, be equipped with corresponding annular recess on the faying surface of this upper and lower plectane, ball is installed in the annular groove, be equipped with outside annular lip on last plectane upper surface, the following plectane lower surface, the smaller diameter end of described each volute spring is outer respectively to be enclosed within on the corresponding annular lip.

Described base upper surface, rotation are equipped with annular retaining ring on the pedal lower surface, and the larger diameter end of described each volute spring is placed in the corresponding annular retaining ring in respectively.

Described rotation pedal upper surface is provided with several projections, and described torsion bar has four, and evenly distributes around the guide post periphery.

A kind of waist-twisting machine according to the utility model provides has following advantage with respect to prior art:

The first, on this waist-twisting machine, spring assembly is two volute springs, and the larger diameter end of two volute springs is connected with base and rotation pedal respectively, make and rotation pedal steadily lifting and rotation have effectively reduced of the wearing and tearing of rotation pedal, the service life of having improved this waist-twisting machine guide post.Simultaneously, the spring of inverted cone-shaped structure is in compression process, and suppressed range is very big, and elastic force is stronger, helps to increase the sway one's hips amplitude of user when taking exercise, and improves train on.

Second, on this waist-twisting machine, be connected with a slide between two volute springs, the rotation pedal can drive connected volute spring simultaneously and rotate on slide when rotated, because the friction media on the slide is a ball, very little of its frictional force, can bring influence to the rotation of rotation pedal hardly, thereby, stable performance in its use.

The 3rd, on this waist-twisting machine, torsion bar is made up of rigid column and the soft post that is threaded in these rigid column two ends, be in when the next at the rotation pedal, each soft major gene bends and torsional deformation and accumulation of energy simultaneously with the rotation of rotation pedal, this energy can help rotation pedal spinning reduction, its structure very rationally.

Description of drawings:

Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the sectional structure schematic diagram of A-A among Fig. 1;

Fig. 3 is the structure for amplifying schematic diagram of I among Fig. 1.

The specific embodiment:

With reference to Fig. 1, Fig. 2, Fig. 3, according to a kind of waist-twisting machine described in the utility model, comprise base 1, be located at the rotation pedal 2 of base 1 upside, base 1 mid portion is provided with a guide post 11, rotation pedal 2 is slidably mounted in guide post 11 upper ends, one spring assembly 3 is coated on the guide post 11, spring assembly 3 comprises two volute springs 31 and connects the slide 4 of two volute springs 31, base 1 upper surface, the larger diameter end that is equipped with annular retaining ring 6, two volute springs 31 on rotation pedal 2 lower surfaces is placed in respectively in the annular retaining ring 6 on base 1 and the rotation pedal 2, the smaller diameter end of two volute springs 31 respectively with slide 4 on, the lower surface connects.The setting and the method for attachment of above-mentioned volute spring 31 and annular retaining ring 6, can guarantee to rotate pedal 2 rotates and lifting stably, of the wearing and tearing of rotation pedal have been reduced to guide post, simultaneously, volute spring 31 is because the advantage of self, also can help to increase the sway one's hips amplitude of user when taking exercise, improve train on.
