The pedals are connected to the support frame via hinges or a transmission mechanism, allowing them to move within a fixed trajectory to train lower limb strength.

[0004] However, existing double-position leg press devices generally suffer from cumbersome operation and low efficiency in height adjustment. The devices typically require specific tools to loosen or tighten bolts to complete the height adjustment, which is not only time-consuming but also inconvenient for users, especially those lacking specialized tools or operating experience. Therefore, a new type of double-position leg press device is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a new type of double-position footrest, which aims to improve the problem that the equipment usually requires the use of special tools to remove bolts in order to adjust the height of the equipment, which is prone to causing long time consumption.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel two-position foot pedal device includes a support frame, with multiple foot pedals on the outer wall of the support frame and an angle adjustment component on the outer wall of each foot pedal. Fixing blocks are fixedly connected to both sides of the support frame, and a connecting tube is rotatably connected inside each fixing block. A seat cushion frame is provided on the outer wall of each connecting tube, and a height adjustment component is provided on the outer wall of the seat cushion frame.

[0008] The height adjustment assembly includes multiple lifting tubes, each of which is slidably connected to the outer wall of the connecting tube.

Each connecting post has a connecting shaft fixedly connected inside, and each connecting shaft has a connecting block rotatably connected to its outer wall. The connecting block fits against the fixed tube.

[0009] As a further description of the above technical solution:

[0010] Each of the connecting posts is provided with a spring on its outer wall, one end of each spring is fixedly connected to the inner wall of the fixing tube, and the other end of each spring is fixedly connected to the outer wall of the locking post.

[0011] As a further description of the above technical solution:

[0012] The bottom of each of the lifting tubes is fixedly connected to the top of the seat cushion frame, and a support plate is fixedly connected to one side of each of the seat cushion frames;

[0013] As a further description of the above technical solution:

[0014] The angle adjustment assembly includes multiple worm gears, the worm gears are located on one side of the foot pedal, and support tubes are fixedly connected to both sides of the support frame;

[0015] As a further description of the above technical solution:

[0016] A support block is fixedly connected to the outer wall of the support frame 1, and multiple support frames 2 are fixedly connected to the outer wall of the support block. A worm gear is rotatably connected inside each of the support frames 2 on one side.

[0017] As a further description of the above technical solution:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a novel double-position footrest, comprising a support frame 1, a plurality of foot pedals 20 being provided on the outer wall of the support frame 1, an angle adjustment component being provided on the outer wall of the foot pedals 20, a fixing block 21 being fixedly connected to both sides of the support frame 1, a connecting pipe 2 being rotatably connected inside each fixing block 21, a seat cushion frame 4 being provided on the outer wall of each connecting pipe 2, and a height adjustment component being provided on the outer wall of the seat cushion frame 4.

[0033] The height adjustment assembly includes multiple lifting tubes 3, each slidably connected to the outer wall of a connecting tube 2. Through sliding engagement with the connecting tube 2, the height of the seat frame 4 is adjusted. Each connecting tube 2 has multiple slots 6 inside, which engage with locking posts 8 to form a stable locking structure, thus fixing the position of the lifting tube 3 and ensuring the adjusted height remains constant. Fixed tubes 5 are fixedly connected to both sides of each lifting tube 3, providing guidance and support for the sliding of the connecting post 7 and enhancing the stability of the internal structure of the lifting tube 3. A connecting post 7 is slidably connected inside each fixed tube 5, allowing the locking post 8 to move in and out, thereby locking and unlocking the slots 6. A locking post 8 is fixedly connected to one end of each connecting post 7, locking the height by engaging with the slots 6, ensuring the stability of the equipment. A connecting shaft 10 is fixedly connected inside each connecting post 7, driving the rotation of the connecting block 11, which in turn unlocks the locking post 8. Each connecting shaft 10 has a connecting block 11 rotatably connected to its outer wall. The connecting block 11 controls the locking post 8 through its rotation function, and its fit design with the fixed tube 5 provides support during rotation, ensuring smooth operation. Each connecting post 7 has a spring 9 on its outer wall. The spring 9 resets the locking post 8 through its elasticity, further enhancing the locking effect between the locking post 8 and the locking slot 6. One end of each spring 9 is fixedly connected to the inner wall of the fixed tube 5, providing fixed support for the stable operation of the spring 9; the other end of each spring 9 is fixedly connected to the outer wall of the locking post 8, providing the locking post 8 with the elastic force for reset. The bottom of each lifting tube 3 is fixedly connected to the top of the seat frame 4. The fixed design of the lifting tube 3 provides an adjustable support structure for the seat frame 4, allowing it to adapt to different height requirements. Each seat frame 4 has a support plate 22 fixedly connected to one side. The support plate 22 increases the structural support surface, improving the load-bearing capacity and stability of the seat frame 4, thereby ensuring the safety and comfort of the equipment.

[0034] Specifically, during the height adjustment of the seat cushion frame 4, the connecting block 11 is first rotated 90 degrees. This rotation causes the connecting shaft 10 to move, pushing one end of the connecting post 7 and dislodging the locking post 8 from the inner wall of the slot 6. During this process, the movement of the locking post 8 also compresses the spring 9, providing preload for subsequent reset. After completing these steps, the position of the seat cushion frame 4 can be adjusted by sliding the lifting tube 3 up and down on the outer wall of the connecting tube 2, thereby adjusting its height to meet actual usage needs. Once the seat cushion frame 4 is at the appropriate height, the connecting block 11 is rotated again to return it to its initial position, simultaneously causing the locking post 8 to move back to the inner wall of the slot 6, allowing the connecting post 7 to engage with the slot 6. At this point, the spring 9, through its rebound force, further strengthens the engagement between the locking post 8 and the slot 6, effectively fixing the position of the lifting tube 3 and ensuring the stability and safety of the seat cushion frame 4 during use. This design not only enables precise control of height adjustment, but also improves the overall structural robustness and reliability.

[0035] Reference Figure 1 and Figure 3The angle adjustment assembly includes multiple worm gears 16, located on one side of the foot pedal 20. These worm gears engage with the worm gear 15 to precisely adjust the angle of the foot pedal 20. Support tubes 19 are fixedly connected to both sides of the support frame 1, providing guidance and support for the rotation of the connecting column 17, ensuring stability during adjustment. Support blocks 12 are fixedly connected to the outer wall of the support frame 1. These blocks, by stabilizing the support frame 13, provide a stable working environment for the worm gears 16 and related components, thereby enhancing the operational reliability of the equipment. Multiple support frames 13 are fixedly connected to the outer wall of the support block 12. These support frames 13, through their internal rotating connection design, provide support for the worm gear 15 and the connecting column 17, while ensuring coordinated operation between the components. Each support frame 13 on one side is internally connected to a worm gear 15. The worm gear 15 rotates to precisely drive the worm wheel 16, thereby adjusting the angle of the foot pedal 20. One end of each worm gear 15 is fixedly connected to a turntable 14, which provides a manual control point for the rotation of the worm gear 15, allowing users to flexibly adjust the angle of the foot pedal 20. The worm gear 15 meshes with the worm wheel 16. This meshing structure not only ensures smooth transmission but also prevents accidental rotation of the foot pedal 20 through the self-locking characteristic of the worm gear 15, further enhancing the safety and practicality of the equipment. Each worm wheel 16 has a connecting post 17 fixedly connected to its inner wall. The connecting post 17, through its rotation, transmits the power of the worm wheel 16 to the foot pedal 20, completing the angle adjustment. Both ends of the connecting post 17 are rotatably connected inside the support frame 13. This rotatable connection provides flexible movement support while ensuring smooth power transmission. Each connecting post 2 17 is rotatably connected inside the support tube 19. The support tube 19 further provides support and guidance for the rotation of the connecting post 2 17, improving the stability of the component during operation. Multiple connecting blocks 2 18 are fixedly connected to the outer wall of each connecting post 2 17. The connecting blocks 2 18, through their structural design, directly transmit power to the foot pedal 20, ensuring the accuracy and synchronization of angle adjustment. Each connecting block 2 18 is fixedly connected to the outer wall of the foot pedal 20 on one side. This fixed connection applies the force for angle adjustment to the foot pedal 20, achieving the final execution of the angle adjustment function, while simultaneously enhancing the stability and coordination between the foot pedal 20 and the overall structure.

[0036] Specifically, in the process of adjusting the angle of the foot pedal 20, the turntable 14 is first rotated. The rotational force of the turntable 14 drives the worm gear 15 to rotate. The rotation of the worm gear 15 further drives the meshing worm wheel 16 to rotate synchronously. The rotation of the worm wheel 16 is used to precisely adjust the angle of the foot pedal 20, thereby achieving flexible adjustment of the position of the foot pedal 20. This design, through the cooperation of the worm gear 15 and the worm wheel 16, not only achieves precise control of the angle of the foot pedal 20, but also utilizes the self-locking characteristic between the worm gear 15 and the worm wheel 16 to effectively prevent the foot pedal 20 from accidentally rotating or loosening after adjustment, thus ensuring the stability and safety of the foot pedal 20 during use. This design improves the applicability and operational reliability of the equipment, adapts to the diverse usage needs in different scenarios, and also optimizes the user experience, making angle adjustment more convenient and efficient.

[0037] Working principle: During the height adjustment of the seat frame 4, the connecting block 11 is rotated 90 degrees. The connecting shaft 10 pushes the locking pin 8 at one end of the connecting column 7 out of the inner wall of the slot 6, and pushes the spring 9 to compress. Then, the lifting tube 3 slides up and down on the outer wall of the connecting tube 2. When the seat frame 4 moves to the appropriate height, the connecting block 11 is rotated again to reset the connecting block 11 and move the locking pin 8 back to the inner wall of the slot 6. At the same time, the rebound force of the spring 9 enhances the locking effect between the locking pin 8 and the slot 6, thus fixing the position of the lifting tube 3. During the angle adjustment of the foot pedal 20, the turntable 14 is rotated. The rotation force of the turntable 14 drives the worm gear 15 to rotate, and the worm wheel 16 also rotates synchronously. The rotation of the worm wheel 16 controls the angle of the foot pedal 20. The self-locking property between the worm gear 15 and the worm wheel 16 prevents the foot pedal 20 from rotating accidentally, thus enhancing the applicability of the equipment.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
