[0047] Reference Figure 1 With attached Figure 2 The present application provides a connecting rod structure, including a main frame 100, a steering member 300, a connecting member 400, a transmission member 500 and a resistance source assembly 200; wherein the resistance source assembly 200 includes a rotating end and a resistance end, the rotating end is rotatably connected to the other end of the main frame 100, the resistance end extends in a direction away from the main frame 100, and the resistance end is used to place a load; the steering member 300 is rotatably arranged on the top of the main frame 100; one end of the connecting member 400 is rotatably arranged on the steering member 300, and the other end is rotatably connected to the resistance source assembly 200, and the connection point between the connecting member 400 and the resistance source assembly 200 is located between the rotating end and the resistance end; one end of the transmission member 500 is rotatably arranged on the steering member 300, and the transmission member 500 is used to connect with the swinging member grasped by the trainer. The trainer operates the swinging member for training, and the transmission member 500 pulls the steering member 300 to rotate relative to the main frame 100, so that the connecting member 400 pulls the resistance source assembly 200 to rotate relative to the main frame 100.

[0048] In some embodiments, the main frame 100 is a rod-shaped component, and the main frame 100 includes a top and a bottom. One end of the main frame 100 is the top. The top of the main frame 100 can be bent in any direction to form an angle. The value of the angle is set according to actual conditions, and it can also be an inclined straight rod. The embodiment of the present application does not specifically limit the shape of the main frame; the other end of the main frame 100 is the bottom. The bottom of the main frame 100 is placed on a horizontal plane. When the main frame 100 is placed on the horizontal plane, the bent end of the main frame 100 is higher than the other end.

[0049] In some embodiments, the resistance source assembly 200 is disposed at one end of the main frame 100 close to the horizontal plane. The resistance source assembly 200 includes a rotating end and a resistance end. The resistance source assembly 200 is rotatably connected to the end of the main frame 100 close to the horizontal plane through the rotating end, and the resistance end of the resistance source assembly 200 extends in a direction away from the main frame 100.

[0050] In some embodiments, the resistance source assembly 200 includes a rotating member 201, a resistance member 202, an adjusting member 203 and a connecting member 204, wherein one end of the rotating member 201 and one end of the adjusting member 203 are both rotatably disposed on the main frame 100 to constitute the rotating end of the resistance source assembly 200; one end of the resistance member 202 is rotatably connected to an end of the rotating member 201 away from the main frame 100, and the other end of the resistance member 202 is used to place a counterweight block to constitute the resistance end of the resistance source assembly 200; one end of the connecting member 204 is rotatably connected to an end of the adjusting member 203 away from the main frame 100, and the other end of the connecting member 204 is fixedly disposed outside the resistance member 202; the resistance source assembly 200 is used to provide resistance for the rotating member 201, and the cooperation between the adjusting member 203 and the resistance member 202 is used to adjust the size of the resistance by changing the resistance arm S without changing the number of counterweight blocks.

[0051] Reference Figure 1 In some embodiments, the rotating member 201 and the adjusting member 203 are arranged in parallel, and the connection point between the adjusting member 203 and the main frame 100 is located on the side of the connection point between the rotating member 201 and the main frame 100 close to the steering member 300, that is, the rotation connection point between the rotating member 201 and the main frame 100 is located below the rotation connection point between the adjusting member 203 and the main frame 100.

[0052] Reference Figure 3 The trainee pushes the swinging member 600 to move away from the main frame 100, thereby pulling the steering member 300 to rotate through the transmission member 500, and the second turning point 302 of the steering member 300 rotates clockwise around the first turning point 301, and then pulls the rotating member 201 to swing diagonally upward through the connecting member 400. The vertical distance from the connection point between the rotating member 201 and the main frame 100 to the gravity line of the resistance end of the resistance member 202 is the length of the resistance arm S. During the swinging process, the adjusting member 203 is rotationally connected to the resistance member 202, the angle between the resistance member 202 and the rotating member 201 increases, and the length of the resistance arm S increases accordingly, while the load at the resistance end of the resistance member 202 remains unchanged. Therefore, the resistance in the process of the connecting member 400 pulling the rotating member 201 to swing diagonally upward increases as the length of the resistance arm S increases.

[0053] Reference Figure 2 In some embodiments, the steering member 300 is a plate-shaped member, and the steering member 300 includes a base plate 304, a first turning point 301, a second turning point 302 and a third turning point 303, wherein the first turning point 301 is passed through the base plate 304, and the first turning point 301 is used for rotational connection with the main frame 100; the second turning point 302 is passed through the base plate 304, and the second turning point 302 is used for rotational connection with the connecting member 400; the third turning point 303 is passed through the base plate 304, and the third turning point 303 is used for rotational connection with the transmission member 500.

[0054] Reference Figure 2 In some embodiments, a first distance is set between the first turning point 301 and the second turning point 302; a second distance is set between the second turning point 302 and the third turning point 303; a third distance is set between the first turning point 301 and the third turning point 303; the first distance, the second distance and the third distance are equal, so that the first turning point 301, the second turning point 302 and the third turning point 303 are arranged on the steering member 300 according to the three corner points of an equilateral triangle, increasing the movement range of the second turning point 302 and the third turning point 303 when rotating around the first turning point 301, and avoiding instability or jamming when the base plate 304 rotates.

[0055] Reference Figure 1 With attached Figure 2In some embodiments, when the transmission member 500 does not pull the steering member 300, the distance from the second turning point 302 to the main frame 100 is not less than the distance from the third turning point 303 to the main frame 100, so that when the transmission member 500 pulls the second turning point 302 in a direction away from the main frame 100, the steering member 300 immediately pulls the resistance source assembly 200 in a direction away from the horizontal plane through the third turning point 303 and the connecting member 400, thereby improving the response speed of the resistance source assembly 200 to the movement of the transmission member 500; increasing the rotation stroke of the transmission member 500 around the first turning point 301, thereby supporting the trainee to perform larger training movements through the transmission member 500.

[0056] It should be noted that, in some embodiments, when the transmission member 500 does not pull the steering member 300, the distance from the second turning point 302 to the main frame 100 is not less than the distance from the third turning point 303 to the main frame 100, and the second turning point 302 is used to be rotatably connected to the transmission member 500, and the third turning point 303 is used to be rotatably connected to the connecting member 400, so that when the transmission member 500 pulls the third turning point 303 in a direction away from the main frame 100, the connecting member 400 needs to wait for the second turning point 302 to rotate around the first turning point 301 to the initial position of the third turning point 303, and then pull the resistance source assembly 200 to move in a direction away from the horizontal plane, thereby reducing the response speed of the resistance source assembly 200 to the movement of the transmission member 500 and shortening the rotation stroke of the transmission member 500 around the first turning point 301, so as to be suitable for training when the trainee uses a heavy weight block.

[0057] Reference Figure 2 In some embodiments, the steering member 300 is further provided with an avoidance opening 305, which is provided on the bottom plate 304 and is located between the second turning point 302 and the third turning point 303, so as to increase the range of motion between the transmission member 500 and the connecting member 400, thereby avoiding friction and collision between the transmission member 500 and the connecting member 400, which may cause the steering member 300 to rotate unsmoothly.

[0058] In some embodiments, the connecting member 400 is a rod-shaped component, one end of the connecting member 400 is rotatably provided on the steering member 300, and the other end is rotatably connected to the resistance source system, and the connection point between the connecting member 400 and the resistance source assembly 200 is located between the rotating end and the resistance end, and the connecting member 400 is used to drive the resistance source assembly 200 to move when the steering member 300 rotates.

[0059] In some embodiments, the transmission member 500 is a rod-shaped member, which is rotatably disposed on the steering member 300. The transmission member 500 is used to pull the steering member 300 to rotate relative to the main frame 100, so that the connecting member 400 pulls the resistance source assembly 200 to rotate relative to the main frame 100.

[0060] In some embodiments, the swing member 600 is rotatably disposed at one end of the bending of the main frame 100, the swing member 600 is located on the side of the steering member 300 away from the resistance source assembly 200, the swing member 600 is rotatably connected to the transmission member 500, and the swing member 600 is used to drive the transmission member 500 to rotate relative to the main frame 100, thereby driving the resistance source assembly 200 to move through the steering member 300 and the connecting member 400.

[0061] In some embodiments, the armrest 700 is fixed on the swing member 600 and is located at one end of the swing member 600 away from the main frame 100 . The armrest 700 is used for the trainee to grasp and push the swing member 600 to rotate relative to the main frame 100 .

[0062] In actual use of the connecting rod structure of the present application, the trainee pushes the swinging member 600 to rotate around the bent end of the main frame 100 through the armrest member 700, and one end of the swinging member 600 provided with the armrest member 700 moves in the direction away from the main frame 100 and the horizontal plane, and the swinging member 600 pulls the steering member 300 to rotate around the first turning point 301 through the transmission member 500, and the steering member 300 pulls the rotating member 201 to rotate in the direction away from the horizontal plane through the connecting member 400, and the resistance member 202, one end of which the counterweight is placed, rotates relative to the rotating member 201 under the action of gravity, and the resistance member 202 and the adjusting member 203 rotate relative to each other. During the swinging process, the angle between the resistance member 202 and the rotating member 201 increases, and the length of the resistance arm S increases accordingly, so that the resistance value provided gradually increases in the process of the rotating member 201 moving away from the horizontal plane. Specific embodiment 2

[0064] The present application also provides a connecting rod structure, which is different from the connecting rod structure in the first specific embodiment as follows:

[0065] Reference Figure 4 In some embodiments, one end of the rotating member 201 is rotatably arranged on the main frame 100, and the connecting member 400 is rotatably connected to the rotating member 201; one end of the adjusting member 203 is rotatably connected to the main frame 100, one end of the resistance member 202 is connected to the other end of the adjusting member 203, and the other end of the resistance member 202 is used to place a counterweight block, and the other end of the rotating member 201 is rotatably connected to the connecting member 204, and the connecting member 204 is fixedly connected to the resistance member 202, the rotating member 201 and the adjusting member 203 are staggered, and the connection point of the adjusting member 203 and the main frame 100 is located on the side of the connection point between the rotating member 201 and the main frame 100 away from the steering member 300, that is, the rotation connection point of the rotating member 201 and the main frame 100 is located above the rotation connection point of the adjusting member 203 and the main frame 100.

[0066] Reference Figure 5The trainee pushes the swinging member 600 to move away from the main frame 100, thereby pulling the steering member 300 to rotate through the transmission member 500, and the second turning point 302 of the steering member 300 rotates clockwise around the first turning point 301, and then pulls the rotating member 201 to swing diagonally upward through the connecting member 400. The vertical distance from the connection point between the rotating member 201 and the main frame 100 to the gravity line of the resistance end of the resistance member 202 is the length of the resistance arm S. During the swinging process, the adjusting member 203 and the resistance member 202 rotate relative to each other, and due to the pulling of the adjusting member 203, the angle between the resistance member 202 and the rotating member 201 decreases, and the length of the resistance arm S decreases accordingly, while the load at the resistance end of the resistance member 202 remains unchanged. Therefore, the resistance in the process of the connecting member 400 pulling the rotating member 201 to swing diagonally upward decreases as the length of the resistance arm S decreases.

[0067] In actual use of the connecting rod structure of the present application, the trainee pushes the swing member 600 to rotate around the bent end of the main frame 100 through the armrest member 700, and one end of the swing member 600 provided with the armrest member 700 moves in the direction away from the main frame 100 and the horizontal plane, and the swing member 600 pulls the steering member 300 to rotate around the first turning point 301 through the transmission member 500, and the steering member 300 pulls the rotating member 201 to rotate in the direction away from the horizontal plane through the connecting member 400, and the resistance member 202, one end of which the counterweight is placed, rotates relative to the rotating member 201 under the action of gravity, and the resistance member 202 and the adjusting member 203 rotate relative to each other, and the angle between the resistance member 202 and the rotating member 201 decreases, and the length of the resistance arm S decreases accordingly, so that the resistance value provided gradually decreases in the process of the rotating member 201 moving away from the horizontal plane.

[0068] The connecting rod structure of the present application, in combination with specific embodiment 1 and specific embodiment 2, enables the counterweight block to be set at a position lower than the training position through the cooperation of the steering member 300, the connecting member 400 and the transmission member 500, and enables the trainee to flexibly adjust the direction of force; by setting the avoidance opening 305, it is convenient for the transmission member 500 to pull the steering member 300 to rotate; by setting the adjusting member 203, the resistance member 202 can rotate relative to the rotating member 201, thereby adjusting the size of the resistance arm S. Specific embodiment three

[0070] The present application also provides a fitness equipment, which includes the connecting rod structure in the above-mentioned specific embodiment 1, so that the counterweight block of the fitness equipment can be set at a position lower than the training position, and the trainee can flexibly adjust the force direction; the body parts that the trainee uses the fitness equipment to train are not specifically limited in this embodiment.

[0071] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
