The invention and simplified description do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operate in a particular orientation, and therefore should not be construed as limiting the invention. Furthermore, the terms "first," "second," "third," etc. are used for descriptive purposes only and should not be construed to indicate or imply relative importance.

As shown in Figure 1, Figure 2, Figure 3, and Figure 4:

The present invention has a base 2 on which an abdominal pad 5 and a chest pad 6 are installed, and two handles 11 on the base 2 are respectively on both sides of the chest pad 6 .

The gantry 1 and the base 2 are fixedly connected together by a connecting pipe 17 .

A mounting plate 18 is fixed on the gantry frame 1 . Since the gantry frame 1 and the base 2 are fixedly connected, the mounting plate 18 is equivalent to being fixed on the base 2 .

A foot swing tube shaft 19 is rotatably mounted on the mounting plate 18 with a bearing, one end of the foot swing tube shaft 19 is fixed with a wire rope disc 14 with an outer circumference of an arc, and the other end of the foot swing tube shaft 19 is fixed with a foot swing tube 9, that is, the rotation of the foot pendulum tube 9 can drive the rotation of the foot pendulum tube shaft 19, which in turn drives the wire rope disc 14 to rotate.

The lower part of the foot swing tube 9 is fixedly provided with a skirting foam adjusting disc rotating shaft 41, the skirting foam adjusting disc 42 is rotatably sleeved on the skirting foam adjusting disc rotating shaft 41 with a bearing, and the skirting foam 4 is fixed. On the baseboard foam adjusting disc 42 , the foot swing tube 9 is provided with several baseboard foam adjusting holes (not shown in the figure) distributed on a circle coaxial with the adjusting disc rotating shaft 41 .

A skirting foam adjusting pin 43 is inserted into a skirting foam adjusting hole on the foot swing tube 9 after passing through the skirting foam adjusting disc 42 , so that the skirting foam adjusting disc 42 is fixed on the foot swing tube 9 , that is, the skirting foam 4 is fixed on the foot swing tube 9 .

In addition, by pulling out and inserting the skirting foam adjusting pins 43 into different skirting foam adjusting holes, the skirting foam adjusting disc 42 can be rotated and then fixed, so that the skirting foam 4 can be adjusted in the foot swing tube. 9 on the high and low positions. to meet the needs of different users.

There is an L-shaped counterweight support pipe 15, and one end of the counterweight support pipe 15 is hinged on the gantry 1 with a hinge shaft 151 (because the gantry 1 and the base 2 are fixedly connected, it is equivalent to being hinged on the base 2 above), the other end is hinged on one end of a joint connecting rod 16 with a joint bearing 161 , and the other end of the joint connecting rod 16 is hinged on the wire rope disc 14 with a joint bearing 162 .

The weight support tube 15 is also provided with a barbell piece hanging rod 10 , and a barbell piece 13 can be hung on the barbell piece hanging rod 10 .

The gantry 1 has a counterweight 12 , one end of the wire rope 8 is connected to the counterweight 12 , and the other end 81 of the wire rope 8 is fixedly connected to the wire rope disc 14 . The wire rope 8 goes around several fixed pulleys 7, and at each angle change of the wire rope 8, a fixed pulley 7 is installed on the gantry 1 to ensure that the wire rope 8 moves smoothly.

In actual use:

Use the adjusting pins 3 to insert different counterweights 12, so as to select the wire rope 8 to connect the counterweights 12 with a suitable weight.

An appropriate barbell plate 13 is placed on the barbell plate hanger 10 according to the user's situation.

The user lies on the belly pad 5 and the chest pad 6, grabs the handle 11 with both hands, and lifts the skirting foam 4 from the bottom of the skirting foam 4 with the legs, causing the foot swing tube 9 to drive the foot swing tube shaft 19 to rotate, Then, the wire rope disc 14 is driven to rotate clockwise as shown in FIG. 2 , and the other end 81 of the wire rope 8 follows the wire rope disc 14 and moves clockwise as shown in FIG. 2 , so that the other end of the wire rope 8 is pulled up. Counterweight 12.

At the same time, the joint bearing 162 is driven by the wire rope disc 14 to rotate clockwise as shown in FIG. 2 , that is, it moves upward, the joint connecting rod 16 is driven to move upward, and the joint bearing 161 drives the end of the counterweight support tube 15 Move upward, thereby driving the counterweight support tube 15 to rotate clockwise around the hinge shaft 151 as shown in FIG.

Therefore, only the muscles of the shoulders and buttocks must exert force to overcome the weight of the weight block 12 and the weight of the barbell plate 13 on the barbell plate hanging rod 10 to realize the movement. This back-and-forth exercise exercises the shoulder and buttock muscles.

The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the various embodiments can be referred to each other. The above description of the disclosed embodiments enables any person skilled in the art to make or use the present invention.
