Description
Technical field
The present invention relates to body-building apparatus technical field, more specifically a kind of torsion bar.
Background technique
Occur a kind of small-sized fitness equipment on the market, be named as torsion bar, it is used for the muscular training at each position of hand.
Its structure such as patent CN201220208076.X is recorded, including a tube body, a spring and two gripping members, the tube body be with
Made of flexible material, and the spring has a body portion and two ends, and the body portion is entwined by coil helix shape,
Two ends respectively have a fixed section, which is at least made of a coil, and the extended spot of the fixed section has
One positioning section, which is made of a flat level, and the spring is arranged in the tube body, which stretches respectively
The two sides of the tube body out；And two gripping members all have a closed end and an open end, and the closed end with open
An accommodation space is formed between mouth end, which has a fixed caulking groove at the open end and a positioning is inserted
Hole, and the fixed section of the spring is embedded in the fixation caulking groove, and the positioning section of the spring is inserted in the positioning jack.
The torsion bar has the following deficiencies: separated distant between (1) two gripping member and cannot be adjusted, on manpower one
It can only once hold herein, the point of application can not be adjusted to be suitble to the best spacing of oneself, and in exercise routine, gesture is easily deformed,
Muscle is then easy to pull；(2) by a spring effect, two gripping members reverse simultaneously for torsion part, if wherein anticipated on the other hand
It slips out of the hand outside, then the other hand needs to undertake double reset twisting force, and reset speed is fast, great efforts, and it is easy to strike and arrives human body,
There are security risks.
Summary of the invention
It is an object of the invention to overcome drawbacks described above, provide a kind of structure novel, it is vdiverse in function, using safe, advantageous
The torsion bar for keeping body-building hand-type, reaching best exercise effect.
In order to reach the goals above, the present invention is achieved by the following technical solutions: a kind of torsion bar, feature exist
In, including a connection piece, the both ends of the connector are respectively connected with a torsional spring, it is respectively arranged with sleeve outside each torsional spring,
Free gap is remained between the inner wall of each corresponding casing of the torsional spring, the free end of each torsional spring is right with it
It answers and is connected with a fixed chuck between the inner wall of casing, interval holding is detached between each described sleeve pipe and connector.
The present invention undertakes torsion main part by two torsional springs, and still inevitably two torsional springs are respective certainly for force application part
By holding, however the present invention is arranged casing outside two torsional springs, and their free end is fixed together, two of them casing
It is grip portions, then becomes the manpower point of application, force application part has been carried out into a detour also through casing, between such two hand of manpower
Distance can arbitrarily be placed on casing, that is to say, that the gripping spacing between two hands can be selected arbitrarily, and user can be with
It is adjusted to most preferably hold spacing according to own situation, so as to preferably temper flesh before chest muscle, biceps, triceps, the palm, preceding
Arm is counted on one's fingers flesh, flesh of counting on one's fingers etc..
Just because of the present invention undertakes torsion main part by two torsional springs, two torsional spring torsions respectively undertake half windup-degree,
If then the other hand only needs to undertake the reset twisting force of itself torsional spring, without as existing skill so wherein unexpected on the other hand slip out of the hand
The single spring of art undertakes double reset twisting force, so comparing insurance, reliable and safety.
Preferably, equal separation pad is equipped with a retaining cage ring between each described sleeve pipe and connector.
As discussed above, force application part has been carried out a detour by casing, so the length of casing is simultaneously when torsion casing
It will not compress, and torsional spring is passively reversed, but sleeve is limited and can not be compressed length again, so torsion circle can only be disengaged passively
Between spacing, turn round circle again gradually becomes smaller, so whether being applied to the power that casing is pullled toward centre, retaining cage ring can be played
The effect of retaining casing, to fight this burst of power, to guarantee that torsion bar torsion holds weighing apparatus.
Preferably, being respectively arranged an elastic grip handle outside each described sleeve pipe.
In order to allow take exercise in hold pleasant, so add elastic grip handle outside casing, elastic grip is by EVA material
It is made, EVA material has good flexibility, and the elasticity as rubber still is able to have preferable pliability, thoroughly at -50 DEG C
Bright property and lustrous surface are good, and chemical stability is good, and anti-aging and resistance to ozone intensity is good, non-toxic.
Preferably, equal arranged for interval has several concave volumes on the outer surface of each elastic grip handle.
Bumps form rough surface, so that manpower effect is not easy to skid.
Preferably, being each provided with a counterweight on the free end of each described sleeve pipe, the counterweight passes through a clamping screw
It is fixed on fixed chuck.
Respectively increase a counterweight at the both ends of torsion bar, can be used when dumbbell, extend its auxiliary function.
The utility model has the advantages that the gripping spacing between two hands of (1) present invention can be selected arbitrarily, user can be according to itself feelings
Condition is adjusted to most preferably hold spacing, so as to preferably take exercise.
(2) two torsional spring torsions of the present invention respectively undertake half windup-degree, if so wherein unexpected on the other hand slip out of the hand, then
The other hand only needs to undertake the reset twisting force of itself torsional spring, so comparing insurance, reliable and safety.
