Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a transfer mechanism and fitness equipment. Background Technology

[0002] As people pay more attention to their health, more and more people are starting to use fitness equipment for exercise. Some fitness equipment is equipped with resistance motors, which are connected to resistance cables. Users use the resistance cables to resist the resistance motors in order to achieve the effect of exercising muscles.

[0003] Some fitness equipment includes connected pedals and a stand, with pulley systems for guiding the resistance bands optionally mounted on the stand or pedal 3 (e.g., Figure 1 As shown), specifically, the pulley block 1 is equipped with a mounting structure 2 (as shown). Figure 2 As shown), the vertical bracket or sliding sleeve slidably mounted on it is provided with a mating structure that mates with the mounting structure. Simultaneously, the side of the pedal 3 is also provided with a mating structure 4 for mates with the mounting structure 2 (as shown). Figure 3 As shown, existing equipment can be referenced in Chinese invention patent application number 202120878217.8. The pulley block 1 includes a mounting base 11 and a rotating seat 12 rotatably mounted on the mounting base 11. A roller 13 is rotatably mounted inside the rotating seat 12. When the pulley block is installed on the side of the pedal, the rotating seat interferes with the edge of the pedal due to insufficient height of the mounting base, resulting in a very limited deflection angle. Furthermore, if the tension rope cannot extend parallel to the pedal or at a small angle to the pedal, it will interfere with the rotating seat during certain training exercises, causing friction and affecting the rope's lifespan. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a transfer mechanism, including a main body, the top of the main body is provided with a mating structure for assembling with the mounting structure on the pulley block, and one side of the main body is provided with a mounting structure for assembling with the mating structure on the pedal.

[0006] Furthermore, the mating structure on the main body includes a through groove with a convex cross-section, the through groove connecting to the top surface of the main body, and a locking groove provided on the inner bottom surface of the through groove.

[0007] Furthermore, the mating structure on the main body is inclined.

[0008] Furthermore, the mounting structure on the main body includes a limiting block with a T-shaped cross-section, and the limiting block is provided with an elastic pin assembly.

[0009] Furthermore, the elastic pin assembly includes a pin and an elastic element. The pin is slidably disposed relative to the main body. One end of the pin is a locking end, and the other end is a pulling end, which is exposed on the other side of the main body. The elastic element contacts the pin and the main body respectively to drive the locking end to protrude from the surface of the limiting block.

[0010] Furthermore, the pin component includes a connected T-shaped rod and a pin portion. The head of the T-shaped rod is the pull-out end, and the end of the pin portion is the locking end. One end of the main body is provided with a mounting groove. The middle section of the T-shaped rod passes through the mounting groove. The elastic element is sleeved on the middle section of the T-shaped rod. One end of the elastic element abuts against the pin portion, and the other end of the elastic element abuts against the inner wall of the mounting groove.

[0011] Furthermore, a recessed area is provided on the lower part of one side of the main body, and the limiting block is located in the recessed area.

[0012] To solve the above-mentioned technical problems, the present invention also adopts the following technical solution: a fitness device, including a pedal, a pulley assembly and the above-mentioned transfer mechanism, wherein the side of the pedal is provided with a mating structure for assembling with the mounting structure on the main body; the pulley assembly includes a mounting base and a rotating base rotatably mounted on the mounting base, wherein a roller is rotatably provided in the rotating base, and the mounting base is provided with an mounting structure for assembling with the mating structure on the main body.

[0015] The beneficial effects of this utility model are as follows: The adapter mechanism has a simple structure. When the pulley block is indirectly installed on the side of the pedal through the adapter mechanism, the adapter mechanism raises the rotating seat of the pulley block, allowing the rotating seat to deflect inward at a greater angle. This prevents the tension cable from rubbing against the rotating seat and / or the pedal edge during inward stretching movements, thus extending the service life of the tension cable and reducing the operating cost of the fitness equipment. Furthermore, because the tension cable does not rub against the rotating seat and / or the pedal edge, the resistance data to the motor force can be more precise, allowing users to more accurately control their training data.

[0040] Furthermore, a recessed area 525 is provided on the lower part of one side of the main body 51, and the limiting block 523 is located in the recessed area 525.

[0041] As can be seen from the above description, the recessed area 525 has a sufficient distance from the top surface of the main body 51, and the adapter 5 can effectively raise the pulley assembly 1 installed on it. At the same time, the existence of the recessed area 525 also allows the adapter 5 to be miniaturized.
