For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0028] In addition, the term "plurality" shall mean two or more.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] like Figure 1As shown, a pulley assembly includes: a first mounting plate 1 and a second mounting plate 2 located on both sides, a first fixed pulley 3 and a second fixed pulley 4 arranged on the first mounting plate 1, a reversing wheel assembly 10 arranged on the second mounting plate 2, a third fixed pulley 5 and a fourth fixed pulley 6 fixedly arranged between the first mounting plate 1 and the second mounting plate 2, and a movable pulley assembly arranged between the first mounting plate 1 and the second mounting plate 2, and also includes a first traction rope 11 and a second traction rope 12, one end of the first traction rope 11 is connected to the The first mounting plate 1 is fixedly connected, and the other end thereof passes through the first mounting plate 1 and is fixedly connected to the counterweight assembly after passing through the first mounting plate 1 in sequence. One end of the second traction rope 12 passes through the third fixed pulley 5, the first reversing wheel on the reversing wheel assembly 10, the second movable pulley 9 on the movable pulley assembly, the second reversing wheel on the reversing wheel assembly 10, the second fixed pulley 4, and the fourth fixed pulley 6 in sequence and then extends out. Both ends of the second traction rope 12 are free ends.

[0031] In order to prevent the first traction rope 11 from motion interference during the movement, a fifth fixed pulley 7 is also provided on the second mounting plate 2. The other end of the first traction rope 11 successively passes around the first movable pulley 8, the first fixed pulley 3, and the fifth fixed pulley 7 on the movable pulley assembly, and then passes through the first mounting plate 1 to be fixedly connected to the counterweight assembly.

[0032] like Figure 1 As shown, the movable pulley assembly includes a mounting frame, the first movable pulley 8 is rotatably arranged at one end of the mounting frame, and the second movable pulley 9 is rotatably arranged at the other end of the mounting frame, wherein the first movable pulley 8 is for the first traction rope 11 to pass around, and the second movable pulley 9 is for the second traction rope 12 to pass around, and the axis lines of the first movable pulley 8 and the second movable pulley 9 are inclined. This method can make it easier for the first traction rope 11 and the second traction rope 12 to be routed better and prevent motion interference.

[0033] In this embodiment, the counterweight assembly can use ordinary counterweight weights. In addition, the counterweight assembly can also use counterweight motors, wind resistance, magnetic resistance and water resistance, etc. As the optimal solution, in this embodiment, it is preferred to use a counterweight motor. The structure of the counterweight motor is similar to that of a winch. The first traction rope 11 is wound around the drum and is controlled by the motor to be retracted and released, thereby adjusting the counterweight force. As a further step, since the user's fitness exercise process is also a work process, its energy can also be used, such as using a permanent magnet motor and equipped with a battery for storing electrical energy. During the user's exercise, the permanent magnet motor converts kinetic energy into electrical energy, which is then stored by the battery, and the battery also serves as the power source of the permanent magnet motor. Therefore, the whole process is that the battery first serves as the starting power source of the permanent magnet motor. When the permanent magnet motor is started, a load force is formed. At this time, the user uses the fitness equipment, and in this process, the permanent magnet motor converts power into electrical energy and stores it through the battery. Therefore, the entire fitness equipment does not need to use an external power supply, but only needs to use a battery, and the battery only needs to be able to meet the initial startup of the permanent magnet motor.

[0034] In order to facilitate the installation of each fixed pulley, the first fixed pulley 3, the second fixed pulley 4, the third fixed pulley 5, the fourth fixed pulley 6, and the fifth fixed pulley 7 all include a fixed pulley frame and a pulley body rotatably connected to the pulley frame.

[0035] like Figure 1 As shown, the pulley frames of the third fixed pulley 5 and the fourth fixed pulley 6 are both provided with holes for the second traction rope 12 to pass through. During the fitness process, the user can exercise by holding the two ends of the second traction rope 12 passing through the third fixed pulley 5 and the fourth fixed pulley 6 with both hands.

[0036] like Figure 2 , Figure 3 As shown, a fitness equipment comprises the above-mentioned pulley assembly, an outer shell 13 fixedly connected to the first mounting plate 1 and the second mounting plate 2, and the third fixed pulley 5 and the fourth fixed pulley 6 are connected to the outer shell 13.

[0037] In order to be able to adjust the positions of the third fixed pulley 5 and the fourth fixed pulley 6 to achieve multiple sports movements, one side of the outer shell 13 is provided with parallel guide grooves 14 along its length direction, and the third fixed pulley 5 and the fourth fixed pulley 6 are respectively arranged in the corresponding guide grooves 14. In addition, the other side of the outer shell 13 is provided with a mounting bracket for adjusting the mounting angle of the outer shell 13. The specific structure of the mounting bracket is not the design point of the present application. As long as it is a structure that can achieve multi-angle installation of the outer shell 13, it can be used. For example, when performing stretching movements, the outer shell 13 can be fixed to the wall by the mounting bracket. For fitness personnel of different heights, the positions of the third fixed pulley 5 and the fourth fixed pulley 6 can be adjusted to achieve bench press, and the outer shell 13 can be fixed to the bottom surface and form a certain angle by the mounting bracket. In addition, it can also be used as a rowing machine, and corresponding accessories only need to be installed at both ends of the second traction rope 12.

[0038] In addition, although not shown in the figure, guide wheels may be provided on both sides of the outer shell 13, and both ends of the second traction rope 12 extend from the guide wheels on both sides and are relatively perpendicular to the outer shell 13, thereby enabling a pushing action.

[0039] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
