Abstract
A tension fitness device for double persons belongs to the field of exercise training instruments. A support (4) is fixed on a base (7), upper sides of rotating rings (6) are connected with rotating shafts (5) while lower sides of the rotating rings (6) are connected to upper ends of springs (2), grips (1) are fixed at lower ends of the springs (2), and upper sides of the rotating shafts (5) are welded to the lower side of the support (4) after being fixed in connecting shafts (3). Each exerciser holds the grips by both hands and can take exercises by means of pulling the springs to rotate. The tension fitness device is simple in structure, small in size, convenient in carrying, easy in operation and wide in application range, is not limited by places or time, and is a necessary exercise instrument for schools and families.
Description
Technical field
The present invention relates to a kind of double chest expander, belong to the Excercise training apparatus field.
Technical background
Along with carrying out of nationwide fitness programs, huge variation has taken place in modern society's life.Physical training is that the modern builds up health, prevent disease, adjusting psychology, joy are pleased body and mind, adapted to one of effective means of society, has positive effect in modern times in the social life.There are many people to utilize and sooner or later have sports, satisfied not this hope owing to receive the restriction in time and place.Though many body-building apparatus are arranged at present, for upper limbs take exercise also fewer.This invention is a kind ofly to utilize the short time of having a rest to carry out upper limbs to take exercise, both can save time, can play the body-building apparatus of taking exercises again, to satisfy people's life requirement.
Physical training has many sportsmen that injured phenomenon often takes place in training owing to receive the restriction of place apparatus, weight person's paralysis, and the lighter's soreness of waist and ache in legs brings many inconvenience to sports career.This double chest expander is created the back and in training, is brought auxiliary practice effect for the sportsman.Also can use with the office public place of entertainment in family, be the indispensable health and fitness facilities of school and family.
Summary of the invention
According to above deficiency of the prior art, the technical problem that the present invention will solve is: provide a kind of simple in structure, operation is practical, does not receive the double chest expander of place and time restriction.
The technical solution adopted for the present invention to solve the technical problems is: this double chest expander; It is characterized in that: comprise shake hands, spring, connecting axle, support, rotating shaft, change, base; Support is fixed on the base, and the change top connects rotating shaft, and the below connects the spring upper end; Fixedly shake hands in the spring lower end, the upper fixed of rotating shaft be welded to after in connecting axle support below.Practitioner's both hands are held and are shaken hands, and the pulling spring rotates and can practise.
During use; The people stands under the support both hands and holds two respectively and shake hands, and firmly spurs spring downwards, left, to the right, utilizes human upper limb strength firmly change to be rotated; Let spring uphold and contraction; Spring is upheld long more, and contraction is just big more, and muscle of upper extremity is through coming and going alternating movement up and down to strengthen the strength of muscle of upper extremity.
Compared with prior art, the beneficial effect that the present invention had is: staff is shaken hands, the pulling spring, and safety coefficient is bigger, is difficult for taking place injury accident.This double chest expander makes full use of the mechanics principle of spring, and it is even that spring is shunk with extension, and arm strength strengthens; The human upper limb muscle strength has much; Extension pressure just has much, accelerates each position blood circulation of upper limbs, and waist muscle is strengthened; Improve the function of taking exercises, the arthralgia patient is recovered to have the supplemental treatment effect.The present invention is simple in structure, and volume is little, do not receive place and time restriction, convenient in carrying, and operation easily is applicable to that relatively teenager, person in middle and old age, vast physical training and professional sports sportsman use and the supplemental treatment of diseases related.
Description of drawings
Fig. 1 is the preferred example of the double chest expander of the present invention, wherein: 12 springs, 3 connecting axles, 4 supports, 5 rotating shafts, 6 changes, 7 bases of shaking hands
The specific embodiment
Below in conjunction with accompanying drawing the double chest expander of the present invention is described further:
As shown in the figure: double chest expander, it is characterized in that support 4 is fixed on the base 7, change 6 tops connect rotating shaft 5, the below connects spring 2 upper ends, spring 2 lower ends fixedly shake hands 1, the upper fixed of rotating shaft 5 be welded to after in connecting axle 3 support 4 below.Practitioner's both hands are held and are shaken hands, and the pulling spring rotates and can practise.
Spring can be changed with human upper limb muscle strength size, and the spring of thickness expansion force length also can move up and down the height of support with the human body height.But the rotating shaft bearing replaces.Change can curve with pipe.Base is insertedly in the face.Support can be used square tube and pipe, also can on support two heel posts, set up connecting axle plug hole up and down, up and down the adjustment height.
During use; The people stands under the support both hands and holds two respectively and shake hands, and firmly spurs spring downwards, left, to the right, utilizes human upper limb strength firmly change to be rotated; Let spring uphold and contraction; Spring is upheld long more, and contraction is just big more, and muscle of upper extremity is through coming and going alternating movement up and down to strengthen the strength of muscle of upper extremity.
