Block vertically connects arc support rod, and the top of the arc support rod is provided with corresponding with human body back on backboard, the backboard
Position insertion counter is installed, state flip-flop that the counter be connected by master control system and with master control system and counting are tactile
Send out device composition.
It is preferred that, the first support bar and second support bar are round steel pipe, and the arc support rod is square bar
Pipe.
It is preferred that, the middle part of the second support bar is provided with the first cylinder pad, and the top of second support bar is provided with second
Cylinder pad.
It is preferred that, the surrounding of the backboard is coated with the cushion made using polyurethane material.
It is preferred that, the both sides of the backboard along its length are separately installed with the 3rd cylinder pad and the 4th cylinder pad.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, the utility model on backboard by being provided with Sit-up auxiliary counter, and under the auxiliary of timer, can
It is accurate to obtain training data, and then the physical efficiency of trainer can accurately be tested.
2nd, the utility model is by the way that first support bar and second support bar to be set to be threadedly coupled, with it is simple in construction, deposit
The advantages of putting convenient and low cost, it is easy to popularization and application.
