Description

A kind of fitness equipment

technical field

The invention belongs to the field of body-building equipment, and in particular relates to a body-building abdomen-tightening machine.

Background technique

In daily fitness exercises, sit-ups are the most common exercise, which can exercise abdominal muscles, but for most people, when they first start exercising, their waist strength can only support about 20 sit-ups, so It is difficult to achieve the purpose of exercising, and it is easy to cause the exerciser to lose confidence in exercising. Using this exercise mechanism can save labor during exercise, and allows the exerciser to increase the number of sit-ups to play a role in fitness.

detailed description

The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

With reference to Fig. 1 shown, a kind of body-building abdomen-reducing equipment comprises grip bar 1, and described grip bar 1, described grip bar 1 is connected with main support 11, and described main support 11 is fixed with first cross bar 61, and second Cross bar 62 and the third cross bar 63, one end of back cushion 3 is fixed on the first cross bar 61, and the other end of back cushion 3 is fixed on the main shaft 5, and seat cushion 4 is also fixed on the main shaft 5, and The top of the bar that described main shaft 5 is connected is provided with first fixed wheel 7, and the outside of the bar that is connected with described main shaft 5 is fixed with track 13, and the top of described track 13 is provided with second fixed wheel 8, and the lower end is provided with. There is a third fixed wheel 9.

Further, a movable shaft 10 is arranged above the third fixed wheel 9, and the movable shaft 10 can be moved to change the position of the third fixed wheel.

Further, both ends of the first cross bar 61 , the second cross bar 62 and the third cross bar 63 are fixed on the bracket 2 .

Further, the bottom end of the main bracket 1 is connected to the bottom end of the bracket where the track 13 is located through the bottom bracket 12 .

Principle of the present invention:

During exercise, the exerciser sits on the cushion 3 and leans against the back cushion 4, holds the grip bar 1 with both hands, and passes both legs between the first fixed wheel 7 and the second fixed wheel 8, and steps on the second fixed wheel On the three fixed wheels 9, the third fixed wheel 9 can adjust the height according to the height of the exerciser so that the exercise puts the legs on it, and then just can start to take exercise.
