Technical Field
[0001] This utility model relates to the field of exercise bike technology, specifically to a safety protection mechanism for exercise bikes. Background Technology
[0002] Safety protection mechanisms are essential devices used in exercise bikes to protect users from injury. They ensure users maintain a stable posture during high-intensity exercise, reducing the risk of falls and effectively protecting user safety during exercise. For example, invention patent CN115845325A discloses a magnetically controlled exercise bike with safety protection functions. The bike includes a main body, a fixed block fixedly connected to one end of a fixed plate, and a first groove inside the fixed block. A first stabilizing plate is fixedly connected inside the first groove. This patent uses a disc on the outer wall of a first driven shaft, a pressing plate on the outer wall of the disc, a first rotating rod inside the first groove, and a rotating plate at one end of the first rotating rod to fix the position of the support rod. In this patent, when the magnetically controlled exercise bike is in use, the user needs to sit on it to operate it, similar to riding a bicycle. If the user accidentally falls off the magnetically controlled exercise bike, the adjustable safety device will prevent the user from falling and thus avoid injury. However, in existing technology, the exercise bike lacks a rotating structure during use. Components such as the top rod, connecting rod, and connecting plate cannot be easily rotated to their designated positions, making it inconvenient for users to sit on the exercise bike and thus hindering its usability. Therefore, improvements are needed. Utility Model Content

By design, the first bearing 6 can support the rotation of the rotating rod 5. A first bevel gear 7 is fixedly connected to the rotating rod 5. A second bevel gear 8 meshes with the outer side of the first bevel gear 7. A threaded rod 9 is fixedly sleeved inside the inner ring of the second bevel gear 8. A second bearing 10 is fixedly sleeved inside the connecting plate 3. The threaded rod 9 is fixedly sleeved inside the inner ring of the second bearing 10. By design, the second bearing 10... The device can support the rotation of the threaded rod 9. The connecting plate 3 is rotatably connected to the threaded rod 9. The outer side of the threaded rod 9 is connected to the threaded sleeve 11 by a thread. The outer side of the threaded sleeve 11 is slidably connected to the connecting sleeve 12. The connecting sleeve 12 is fixedly connected to the connecting plate 3. The upper end of the connecting plate 3 is fixedly connected to the sliding sleeve 13. The inner side of the sliding sleeve 13 is slidably connected to the connecting rod 14. The upper end of the connecting rod 14 is fixedly connected to the top rod 15. The top rod 15 is fixedly connected to the threaded sleeve 11. By rotating the threaded rod 9, the threaded rod 9 and the threaded sleeve 11 undergo threaded movement. The movement of the threaded sleeve 11 drives the top rod 15 and the connecting rod 14 to move. After the threaded sleeve 11, the top rod 15 and the connecting rod 14 move to the designated position, the height of the device can be adjusted, allowing the device to be adjusted to the designated position for use.
[0022] Please see Figure 2-5 The rotating structure 4 includes a hinge 41. The hinge 41 is fixedly connected to the fixed plate 2. The hinge 41 is fixedly connected to the connecting plate 3. The connecting plate 3 has a slot 42 inside. A slider 43 is slidably connected inside the slot 42. A support ring 44 is fixedly connected to the lower end of the slider 43. A pull rod 45 is fixedly connected to the lower end of the support ring 44. A handle 46 is fixedly connected to the lower end of the pull rod 45. By designing the pull rod 45, the slider 43 and other components can be moved.
[0023] Please see Figure 5The fixed plate 2 has a sliding connection to a pull rod 45 inside, and an elastic sponge 47 is provided on the outside of the pull rod 45. One end of the elastic sponge 47 is fixedly connected to the support ring 44, and the other end of the elastic sponge 47 is fixedly connected to the fixed plate 2. By designing the elastic sponge 47, the support ring 44 has an elastic force. The fixed plate 2 has a guide groove 48 inside, and a guide block 49 is slidably connected inside the guide groove 48.

The rotation of the top rod 15 drives the connecting rod 14 and connecting plate 3 and other components to rotate to the designated position, so that the person can sit on the exercise bike 1, and the device is easy to use.
[0025] When the device needs height adjustment, rotating rod 5 is rotated. Rotating rod 5 drives the first bevel gear 7 to rotate, which in turn drives the second bevel gear 8 to rotate. The second bevel gear 8 then drives the threaded rod 9 to rotate. The rotation of the threaded rod 9 causes threaded movement with the threaded sleeve 11, resulting in relative displacement of the threaded sleeve 11. The upward movement of the threaded sleeve 11 drives the push rod 15 to move upward, which in turn drives the connecting rod 14 to move upward. After the threaded sleeve 11, push rod 15, and connecting rod 14 move upward to the designated position, the height of the device is adjusted, allowing the device to be adjusted to the designated position for use.
