Abstract
The invention discloses a kind of adjustable power-assisted abdominal boards.It include body frame and be hinged on body frame one end and can along pin joint reciprocally swinging upper body supporting board carriage, a mandrel for being used to install eight word springs arranged along body frame width is installed with body frame, one eight word spring is at least installed on mandrel, one elastic edge of eight word springs is fitted in the bottom of body frame, and an elastic edge is fitted on upper body supporting board carriage in addition.After above-mentioned structure, when needing to carry out the regulation of auxiliary dynamics, increase or decrease the elastic force effect quantity of the contact between body frame bottom plate, upper body supporting board carriage of eight word springs, it just can conveniently adjust the bounce-back power-assisted after upper body supporting board carriage is pushed, its smart structural design, easy to adjust and manufacturing cost is low, using effect is good.
Description
Technical field
The present invention relates to a kind of sit-ups Special training device tool, specifically a kind of adjustable power-assisted abdominal boards.
Background technology
Sit-ups are, to waist, the very effective exercising way in belly position, can to make to be certainly by sit-ups training
Oneself stature is more perfect, and in order to improve training effect, in the market has occurred in that diversified dedicated for sit-ups
Exercising device, although supplemental training can be played by being performed physical exercise using exercising device, thus reach improve training effect mesh
, when being performed physical exercise using traditional sit-up trainer material, it is generally necessary to which both hands embrace head, cervical traction drives body fortune forward
It is dynamic, all it is fixed yet with existing exercising device in the process, therefore be difficult to play a part of synkinesia, after
Carry out in the market and also occur in that some can provide the training device of synkinesia, but on the one hand its complex structural designs, manufacture
Cost is high, still further aspect, and its dynamics size aided in is difficult to be adjusted, and using effect is poor.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in construction, manufacturing cost is low and auxiliary dynamics can be carried out
The adjustable power-assisted abdominal boards of regulation.
In order to solve the above-mentioned technical problem, adjustable power-assisted abdominal boards of the invention, including body frame and it is hinged on body frame
One end and can along pin joint reciprocally swinging upper body supporting board carriage, be installed with one along body frame width on body frame
An eight word springs, one of eight word springs are at least installed on the mandrel for being used to install eight word springs of direction arrangement, mandrel
Elastic edge is fitted in the bottom of body frame, and an elastic edge is fitted on upper body supporting board carriage in addition.
The eight words spring is set in even-even, is mounted with the middle part of the mandrel between middle a pair of eight word springs
Helical spring, the helical spring can to helical spring both sides eight word springs apply a thrust.
A shoulder is fixedly installed in the middle part of the mandrel, the both sides of the shoulder are pressured respectively helical spring.
The left and right ends of the mandrel have is rotary with adjusting nut on thread segment, the thread segment.
After above-mentioned structure, due to body frame bottom set the mandrel for being provided with eight word springs, thus when need into
When row auxiliary dynamics is adjusted, increase or decrease between the elastic force effect of eight word springs and body frame bottom plate, upper body supporting board carriage
Contact quantity, just can conveniently regulation upper body supporting board carriage push after bounce-back power-assisted, its smart structural design, it is easy to adjust and
Manufacturing cost is low, in addition, the helical spring being cased with mandrel, makes eight word springs produce one and depart from body frame bottom plate and upper body supporting plate
The trend of support frame stress surface, improves using effect, furthermore, the left and right ends of mandrel are provided with adjusting nut, tighten nut
It can overcome helical spring resistance that multiple eight words springs are pressed into body frame bottom plate and upper body supporting board carriage stress surface active region, enter one
Step improves using effect.
Brief description of the drawings
Fig. 1 is the main structure diagram of adjustable power-assisted abdominal boards of the invention；
Fig. 2 is the side structure schematic view of adjustable power-assisted abdominal boards of the invention.
Embodiment
With reference to the accompanying drawings and detailed description, the adjustable power-assisted abdominal boards of the present invention is made further specifically
It is bright.
As illustrated, the adjustable power-assisted abdominal boards of the present invention, including body frame 1 and the one end and the energy that are hinged on body frame 1
One is installed with enough upper body supporting board carriages 2 along pin joint reciprocally swinging, body frame 1 to arrange along body frame width
The mandrel 3 for being used to install eight word springs, the word spring 4 of even-even eight, an elastic edge of eight word springs 4 are installed on mandrel 3
The bottom of body frame is fitted in, an elastic edge is fitted on upper body supporting board carriage in addition, wherein, the middle part of described mandrel 3
The helical spring 5 between middle a pair of eight word springs 4 is mounted with, helical spring can give eight word bullets of helical spring both sides
Spring applies a thrust, and the word spring of opening eight is produced into one departs from becoming for body frame bottom plate and upper body supporting board carriage stress surface
Gesture；When increasing or decreasing the contact quantity between the elastic force action edge and body frame bottom plate and upper body supporting board carriage of eight word springs
When, it just can conveniently adjust the bounce-back power-assisted after upper body supporting board carriage is pushed.
Further, the middle part of described mandrel 3 is fixedly installed a shoulder 6, and the both sides of shoulder 6 are pressured respectively spiral shell
Spring is revolved, the left and right ends of mandrel 3, which have, is rotary with adjusting nut 7 on thread segment, thread segment, the screw thread that mandrel two ends are set coordinates
Adjusting nut, tightening nut can overcome helical spring resistance that multiple eight words springs are pressed into body frame bottom plate and upper body supporting board carriage
Stress surface active region.
