[0019] The utility model will be further described below in combination with the drawings and embodiments.

[0020] ​​In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0021] like Figures 1 to 5 As shown, a gear adjustment module includes a main control body 1 and a circuit board 2. The main control body 1 is provided with a plurality of horizontal through holes 3 and a plurality of vertical accommodating holes 4. The horizontal through holes 3 correspond to the vertical accommodating holes 4 one by one and are cross-connected. Each vertical accommodating hole 4 is provided with an electromagnet 5, a metal movable shaft 6 and an elastic member 7. The elastic member 7 is located between the metal movable shaft 6 and the electromagnet 5. The electromagnet 5 is electrically connected to the circuit board 2. The metal movable shaft 6 is provided with a through hole. When the electromagnet 5 is powered off, the through hole on the metal movable shaft 6 is connected to the horizontal through hole 3 on the main control body 1. When the electromagnet 5 is powered on, the metal movable shaft 6 is attracted to move along the vertical accommodating hole 4 to block the horizontal through hole 3 on the main control body 1.

[0022] The gear adjustment module can be used in a strength fitness station, which is equipped with multiple hydraulic cylinders or pneumatic cylinders. When the electromagnet 5 is not energized, the piston rod of the hydraulic cylinder (or pneumatic cylinder) can pass through the transverse through hole 3 below the electromagnet 5. When the electromagnet 5 is energized, the metal movable shaft 6 below the electromagnet 5 blocks the corresponding transverse through hole 3, thereby blocking the movement of the piston rod. The training gear is adjusted according to the number of blocked piston rods. The free combination of multiple electromagnets 5 and related functional parts can produce a variety of combined gear shifts, which has obvious advantages. There is no need for precision-made parts such as screw rods and motors, and the product is cost-effective. The application of the gear adjustment module is not limited to strength fitness stations, but can also be applied to other fitness equipment that requires a piston rod to adjust the gear.

[0023] In the specific structure, a vertical receiving hole 4 runs through the top surface of the main control body 1. Each electromagnet 5 is inserted into the corresponding vertical receiving hole 4 from top to bottom. The top surface of the main control body 1 is provided with a wiring groove 9. The side wall of each vertical receiving hole 4 is provided with a notch 13 to connect to the wiring groove 9. The circuit board 2 is connected to one side of the main control body 1. The wires of each electromagnet 5 pass through the wiring groove 9 to connect to the circuit board 2. The provision of the wiring groove 9 facilitates the organization of the wires and avoids the tangled wires.

[0024] The main control body 1 in this embodiment is integrally formed. In other embodiments, the main control body 1 can also be assembled from two or more parts. In this case, the vertical accommodating hole 4 does not have to pass through the top surface of the main control body 1, and the electromagnet 5 can also be installed in the vertical accommodating hole 4.

[0025] The fixed plate 8 is connected above the main control body 1, and all the electromagnets 5 are installed on the fixed plate 8. Specifically, threaded holes are arranged on the electromagnets 5, and screw mounting holes are arranged on the fixed plate 8. The electromagnets 5 are fixed on the fixed plate 8 by screws. Alternatively, the electromagnets 5 and the fixed plate 8 can be connected by means of glue or welding. The fixed plate 8 covers all the gaps 13 and at least partially covers the wire routing groove 9, that is, the fixed plate 8 covers the wires to avoid the exposure of the wires and affect the appearance. In addition, the wires are ensured to be located in the wire routing groove 9 to avoid disorder. After all the electromagnets 5 are fixed on the fixed plate 8, the fixed plate 8 is fixed on the main control body 1 by means of screws or glue.

[0026] Preferably, all the vertical accommodating holes 4 are located on the same side of the wire routing groove 9 and arranged in a row. The wire routing groove 9 is linear and penetrates through two side surfaces of the main control body 1, which is beneficial to the machining of parts.

[0027] A plurality of hexagonal columns 10 are installed on the side of the main control body 1 close to the circuit board 2. The circuit board 2 is connected with the hexagonal columns 10 by screws, so that there is a gap between the circuit board 2 and the main control body 1 for wiring operation and heat dissipation of the circuit board 2.

[0028] The elastic member 7 includes but is not limited to a spring, a high polymer elastic block, and a metal spring piece. In this embodiment, the elastic member 7 is preferably a spring. The top surface of the metal movable shaft 6 is provided with a groove, and the lower end of the spring is inserted into the groove. The upper end of the spring pushes against the bottom surface of the metal movable shaft 6.

[0029] The shape of the metal movable shaft 6 is not limited, and the cross section thereof can be circular, polygonal, or special-shaped. In this embodiment, the lower part of the inner wall of the vertical accommodating hole 4 extends outwards to form two opposite bosses 11. The upper part of the metal movable shaft 6 extends outwards to form two opposite limiting portions 12. The metal movable shaft 6 is inserted into the vertical accommodating hole 4 from top to bottom, and the two bosses 11 and the two limiting portions 12 cooperate to limit the downward stroke of the metal movable shaft 6. The electromagnet 5 is fixed on the fixed plate 8, so the electromagnet 5 does not shift whether it is powered or not. The spring is located between the electromagnet 5 and the metal movable shaft 6. When the electromagnet 5 is not powered, the spring pushes against the metal movable shaft 6, so that the two limiting portions 12 of the metal movable shaft 6 are located on the two bosses 11. When the electromagnet 5 is powered, the metal movable shaft 6 is attracted by the electromagnet 5 and moves upwards to block the horizontal through hole 3 on the main control body 1, so that the piston of the hydraulic cylinder is blocked by the metal movable shaft 6 and cannot move, thereby adjusting the training gear of the strength training.

[0030] The plurality of metal movable shafts 6 cooperate with the plurality of electromagnets 5, and each electromagnet 5 is controlled independently. Therefore, the number of horizontal through holes 3 blocked on the main control body 1 is adjustable, so that various combinations of gear shifting can be generated.

[0031] The suction force of the electromagnet 5 is not fixed size, and can be selected according to different requirements of products.

[0032] The above description is only used to illustrate the technical solutions of the present application, and is not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features therein can be replaced by equivalents; and these modifications or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, therefore, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
