As shown in Figure 1 and Figure 2:

The present invention has a base 1 on which a seat pad 10 , a back pad 9 that can be adjusted back and forth, and a head pad 8 above the back pad 9 are mounted.

The gantry 7 and the base 1 are connected as a whole by two connecting pipes 2 .

A mounting plate 15 is fixed on the gantry frame 7, and a foot swing tube rotating shaft 16 is rotatably installed on the mounting plate 15 with a bearing. One end of the foot swing pipe rotating shaft 16 is fixed with a wire rope cam plate 6 whose outer circumference is a cam curve. The other end of the tube shaft 16 is fixed with a fan-shaped foot swing tube adjustment plate 19. The foot swing tube adjustment plate 19 is provided with several foot swing tube adjustment holes (not shown in the figure). The swing tube rotating shaft 16 is on a coaxial circle.

The swing tube shaft 16 passes through the swing tube 5 .

A sway tube adjusting pin 20 passes through the upper part of the sway tube 5 and then is inserted into a sway tube adjusting hole on the sway tube adjusting plate 19, so that the sway tube 5 is fixed on the sway tube shaft 16, and also That is, the rotation of the swing tube 5 will drive the swing tube shaft 16 to rotate, thereby driving the wire rope cam plate 6 to rotate.

A barbell piece hanging rod 4 is fixed on the lower part of the foot swing tube 5 .

The lower part of the foot swing tube 5 is fixedly provided with a foam cylinder assembly adjustment disc rotating shaft 21, the foam cylinder assembly adjustment disc 17 is rotatably sleeved on the foam cylinder assembly adjustment disc rotating shaft 21 with a bearing, and the foam circle The cylinder assembly 3 is fixed on the foam cylinder assembly adjustment plate 17, and the foot swing tube 5 is provided with several foam cylinder assembly adjustment holes (not shown in the figure) distributed on a circle coaxial with the adjustment plate rotating shaft 21. .

A foam cylinder assembly adjustment pin 18 passes through the foam cylinder assembly adjustment disc 17 and then is inserted into a foam cylinder assembly adjustment hole on the foot swing tube 5, so that the foam cylinder assembly adjustment disc 17 is fixed on the foam cylinder assembly. On the swing tube 5 , that is, the foam cylinder assembly 3 is fixed on the swing tube 5 .

The mounting plate 15 can also be fixed on the base 1 . Since the base 1 and the gantry 7 are connected as a whole, the mounting plate 15 in this embodiment is actually equivalent to being fixed on the base 1 .

The two guide rods 11 are installed between the gantry 7, the counterweight 14 is equipped with a guide sleeve, and the guide sleeve is sleeved on the guide rod 11, so that the counterweight 14 can slide up and down between the guide rods 11, and one end of the wire rope 12 is connected to the counterweight. On the weight 14 , the other end 121 of the wire rope 12 is connected to the wire rope cam plate 6 . The wire rope 12 goes around several fixed pulleys 13, and at each angle change of the wire rope 12, a fixed pulley 13 is installed on the gantry 7 to ensure the smooth movement of the wire rope 12.

In actual use:

Different counterweights 14 are inserted by means of the latches 22 , so that the steel wire 12 is selected to connect the counterweights 14 with a suitable weight.

A suitable barbell plate is placed on the barbell plate hanger 4 according to the user's situation.

A person sits on the seat cushion 10 , with the body resting on the back cushion 9 and the head cushion 8 .

Pull out the adjustment pin 18 of the foam cylinder assembly, and rotate the foam cylinder assembly adjustment disc 17 around the rotating shaft 21 of the foam cylinder assembly adjustment disc. After rotating a certain angle, insert the adjustment pin 18 of the foam cylinder assembly to make it inserted into a new adjustment hole of the foam cylinder assembly, in this way, the foam cylinder assembly 3 fixed on the foam cylinder assembly adjustment disc 17 also rotates at a certain angle relative to the rotation shaft 21 of the foam cylinder assembly adjustment disc, thereby Its spatial position is adjusted by adjusting the position of the foam cylinder assembly 3 to make it fit the height of the user

Pull out the swing tube adjustment pin 20, make the swing tube 5 rotate around the swing tube shaft 16, and after rotating a certain angle, insert the swing tube adjustment pin 20 to insert it into a new swing tube adjustment hole, so that The position of the foot swing tube 5 changes, and the position of the foam cylinder assembly 3 also changes. By adjusting the position of the foot swing tube 5, the starting position of the user's calf during exercise can be adjusted.

The outer side of the calf is close to the foam cylinder assembly 3, and the calf is lifted, so that the foot swing tube 5 and the foot swing tube shaft 16 are driven to rotate together, thereby driving the wire rope cam plate 6 to rotate, and the rotation of the wire rope cam plate 6 will drive the wire rope. The end portion 121 is rotated upwards and backwards, thereby pulling the steel wire rope 12, thereby pulling up the counterweight 14, and the rotation of the foot swing tube 5 also causes the barbell plate on the barbell plate hanging rod 4 to rise.

Therefore, the movement of the quadriceps must be exerted to overcome the weight of the weight block 14 and the weight of the barbell plate on the barbell plate hanging rod 4 . This back-and-forth exercise works the quadriceps.
