Description
Technical field
The invention belongs to body-building apparatus technical field, is related to a kind of horizontal bar, and more particularly to a kind of multi-functional training combination is single
Thick stick.
Background technology
Horizontal bar is to temper arm strength, promote head to increase, increase lung capacity, take exercises flexibility and the important forging of the sense of equilibrium
Refine apparatus.School playground or park body-building area are typically fitted with the horizontal bar of body-building at present, in order to meet the people of different heights
Demand, generally require that multiple horizontal bars are installed, floor space is larger.
For the problem present on, people have carried out miscellaneous improvement to horizontal bar, and some have also applied for patent, example
As disclosed a kind of electric lifting horizontal bar [application number in Chinese patent literature data:201520552688.4;Granted publication
Number:204952043U], device includes cross bar, the support bar component and lifting rod component of support rail, and support bar component includes two
Hollow tube is thickeied, lifting rod component includes the feed screw nut of two screw mandrels and two cooperation screw mandrels, and feed screw nut is fixed on thickening
Hollow bottom of the tube, thickeies the length of hollow tube and the length of screw mandrel matches, and every screw mandrel bottom is provided with change gear case, two
Change gear case is connected by a synchronous drive link, and Synchronous Transmission bar one end is provided with subtracting for a driving Synchronous Transmission bar rotation
Speed motor, change gear bottom portion, which is provided with, bores the thin end of the scroll.
Above-mentioned lifting horizontal bar is provided with elevating lever and can drive the reducing motor of lifter rod lifting, and it can arbitrarily adjust list
The height of thick stick, can meet the needs of different height students and body-building personnel.But can just be worked because reducing motor needs to be powered,
Therefore can not widely be promoted.
And the overweight chin-up person taking exercise of some own body weights can not overcome own wt and abandon horizontal bar exercise.In
There are such one section of word when examining PE testing:" during selection project, if examinee's body is lighter, height is not that very high can select draws body
Upwards ".It is understood that this section of words indicate the restrictive condition to certain a kind of examinee, if you are that height is too high, body weight is excessively fat, no
Suitably select chin-up project.Examine, community body-building area usually, carefully notice in not exclusively, it has also been discovered that, use horizontal bar
The crowd of exercise is very fixed, young, skill is strong and vigorous.Many basic and horizontal bars that the age is slightly larger, stature is more big and fleshy have no chance,
So that many times horizontal bar is into solitary ornaments equipment.Therefore, research one kind can be adapted to more crowds to make
It horizontal bar, can not be limited by height, body weight, age, allow more people to temper body with horizontal bar with arbitrary
Body, really allow horizontal bar to turn into a kind of not only common, simple but also tangible body-building apparatus, can allow person taking exercise it is " upward " act or very, " to
Under " draw or the various exercise attitudes that push away be our this research purpose.
