As shown in Figure 1 and Figure 2:

The base 1 consists of a floor frame 13' placed on the floor, a rear frame 11' whose lower part is fixed on the floor frame 13', and a seat support frame 12 whose upper and lower ends are respectively fixed on the rear frame 11' and the floor frame 13' 'It consists of three parts,

The rear frame 11' includes inclined left and right inclined rods 111' and 112' that cross each other. The two ends are fixedly connected with the left inclined rod 111' and the right inclined rod 112', thus forming a stable structure. The lower cross bar 114' is fixedly connected with the floor frame 13'.

The seat support frame 12' is inclined.

The above-formed tripod structure ensures the stability of the entire base.

The back cushion 7 is fixed on the seat support frame 12', part A is the seat cushion adjustment structure, and the seat cushion 8 is connected to the seat support frame 12' by the seat cushion adjustment mechanism.

Part A is the seat cushion adjustment structure, which can be adjusted to a suitable exercise position according to the height of different people. The person sits on the seat cushion 8 and the body lies on the back cushion 7 .

As shown in Figure 3:

Part A below the seat cushion 8 is the seat cushion adjustment structure, as shown in Figure 3:

A front cushion adjustment plate 22 is fixed on the front surface of the seat support frame 12', a positioning groove 221 is formed on the front cushion adjustment plate 2 from top to bottom, and a rear surface of the seat support frame 12' is provided with a front cushion The rear seat cushion adjustment plate 23 opposite to the adjustment plate 22 is also provided with positioning grooves from top to bottom.

A seat cushion frame 16 is fixed on the lower surface of the seat cushion 8 , and the seat cushion frame 16 includes two vertical seat cushion plates 161 .

The damper 19 whose lower end is hinged on the seat support frame 12' by the hinge shaft 191 is located between the two seat cushion plates 161, and the top end of the damper 19 is hinged on the bottom surface of the seat cushion 8.

An adjustment handle hinge shaft 181 is set between the two cushion plates 161 , and the sleeve 182 on the adjustment handle 18 is sleeved on the adjustment handle hinge shaft 181 and hinged on the cushion plate 161 , that is, hinged below the cushion 8 .

Two torsion springs 17 are respectively provided on both sides of the adjusting handle 18 . The two torsion springs 17 are sleeved on the adjusting handle hinge shaft 181 , and one end of the two torsion springs 17 is fixed on the adjusting handle 18 and the other end is fixed on the cushion plate 161 , the rear end portion 183 of the adjustment handle 18 is inserted into a positioning groove 221 of the front seat cushion adjustment plate 22 .

There are also three roller shafts 21 erected between the two cushion plates 161. The rollers 201, 202, and 203 are respectively sleeved on the three roller shafts 21 with needle bearings. The rollers 201 and 202 are pressed on the front cushion adjustment plate 22. , the roller 202 plays a limiting role above the adjusting handle 18, and the roller 203 presses on the rear seat cushion adjusting plate 23 to play a supporting role.

The user pulls up the handle portion of the adjusting handle 18, the adjusting handle 18 rotates upward around the hinge shaft 181, and the rear end 183 of the adjusting handle 18 leaves the positioning groove 221, so that the seat cushion 8 and the seat cushion frame 16 can move up and down.

At this time, the two torsion springs 17 are deformed.

If the person is not sitting on the seat cushion 8 at this time, the damper 19 will push up the seat cushion 8 until the user puts down the adjustment handle 18, the two torsion springs 17 are reset, and the adjustment handle 18 is rotated downward around the hinge shaft 181, and the adjustment handle The rear end 183 of 18 is inserted into a new positioning groove 221, so that the seat cushion 8 is lifted up to a new position and fixed.

If a person sits on the seat cushion 8 at this time, the body weight will compress the damper 19, and the seat cushion 8 will move downward until the user puts down the adjustment handle 18, the two torsion springs 17 are reset, and the adjustment handle 18 is rotated downward around the hinge shaft 181, The rear end 183 of the adjustment handle 18 is inserted into a new positioning groove 221, so that the seat cushion 3 is lowered to a new position and fixed.

The three rollers 201 , 202 and 203 are attached to the front seat cushion adjustment plate 22 and the rear seat cushion adjustment plate 23 . The three-point positioning method ensures a suitable clearance for movement, which can be adjusted smoothly without shaking.

As shown in Figure 1 and Figure 2:

The left pull arm 2 is rotatably hinged on the right oblique rod 112' of the rear frame 11' with a horizontal hinge shaft 20'. The lower surface of the pull arm 2 is provided with a left pull arm stopper 22', the position of the right inclined rod 112' corresponding to the left pull arm stopper 22' is provided with a left rear frame stop, and the front end of the left pull arm 2 is provided with a left forearm support The pad 23', the lower surface of the left pull arm is provided with a left joint bearing 24'.

The right pull arm 3 is rotatably hinged on the left oblique rod 111 ′ of the rear frame 11 ′ with a horizontal hinge shaft 30 ′. The lower surface of the pull arm 3 is provided with a right pull arm stop, the position of the left inclined rod 111 ′ corresponding to the right pull arm stop is provided with a right rear frame stop, and the front end of the right pull arm 3 is provided with a right forearm support pad 33 ′, The lower surface of the right pull arm is provided with a right joint bearing 34'.

The above left pull arm 2 and its subsidiary structures and the right pull arm 3 and its subsidiary structures are symmetrically arranged relative to the seat support frame 12'.

The left forearm support pad 23' and the right forearm support pad 33' both face inward and are disposed opposite to each other.

In the case of no force: the left pull arm 2 will rotate downward until the left pull arm stop 22' and the left rear frame stop collide; the right pull arm 3 will rotate downward until the right pull arm stop and the right rear The frame stops collide; this restricts the rotation angle of the left pull arm 2 and the right pull arm 3 to avoid excessive downward movement.

Part of the gantry frame 4 is connected to the rear frame 11' of the base 1 by the upper connecting frame 5 and the lower connecting frame 6, so that the gantry frame 4 is connected with the base 1 as a whole.

The two guide rods 12 are installed in the middle of the gantry frame 4 , and a counterweight 14 with a guide sleeve located in the gantry frame 4 can slide between the guide rods 12 , and the guide sleeve is matched with the guide rod 12 .

The adjustment bolt 15 is inserted into different counterweight blocks 14, and the weight of the corresponding weight block can be lifted. The front end 15 of the adjustment bolt is assembled with a strong magnet. Does not fall off.
