Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the invention.

[0032] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or position relationship are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the invention.

[0033] Please refer to Figures 1-7 As shown, the present invention is a public sports fitness equipment, including an overall bracket 1. A connecting piece 2 is fixedly installed on the overall bracket 1. There are two connecting pieces 2. A buckle mechanism is arranged inside each of the two connecting pieces 2. The buckle mechanism includes a telescopic rod 3 arranged inside the connecting piece 2. One end of the telescopic rod 3 is fixedly installed on the inner wall of the connecting piece 2, and the other end is fixedly installed on a sliding block 4. A return spring 19 is sleeved on the telescopic rod 3. A connecting shaft 5 is rotatably installed on the sliding block 4. A card hole 6 is opened above the connecting shaft 5. The card hole 6 is engaged with a card rod 7. The card rod 7 is fixedly installed on the connecting piece 2. A connecting rod 8 is fixedly installed on the connecting shaft 5. A pedal 9 is fixedly installed on the connecting rod 8. A protection mechanism is arranged below the sliding block 4. The protection mechanism is used to protect the back of the fitness person and prevent people from falling backward during exercise.

[0034] The working principle of a public sports fitness equipment proposed by the present invention is that, first, when the device is not in use, the card hole 6 and the card rod 7 are engaged, so as to fix the connecting shaft 5, and then the connecting rod 8 and the pedal 9 will not be driven to rotate, thereby realizing the locking of the pedal 9, and further preventing children from playing with the pedal 9 back and forth, so as to avoid accidentally hurting themselves and improving safety.

[0035] It should be noted that when the fitness enthusiast uses it, when both feet step on the pedal 9, due to the gravity of the fitness enthusiast himself, the telescopic rod 3 is driven to stretch. At this time, the return spring 19 undergoes elastic deformation and maintains a certain tension force, so that the sliding block 4 moves downward, driving the connecting shaft 5, the connecting rod 8 and the pedal 9 to move downward, and then the card hole 6 is disengaged from the clamping with the clamping rod 7, so that the pedal 9 can swing back and forth.

[0036] Furthermore, when the sliding block 4 moves downward, it synchronously drives the protection mechanism to move, thereby protecting the back of the fitness enthusiast and preventing people from falling backward during exercise.

[0037] Finally, when the fitness enthusiast finishes exercising and both feet leave the pedal 9, the reaction force of the return spring 19 is used to drive the sliding block 4 to move upward, driving the connecting shaft 5, the connecting rod 8 and the pedal 9 to move upward, and then the card hole 6 and the clamping rod 7 are re-clamped, thus completing the locking of the pedal 9.

[0038] In one embodiment, for the above protection mechanism, the protection mechanism includes a rack 10 arranged at the bottom of the sliding block 4. The rack 10 is fixedly installed at the bottom of the sliding block 4, and the rack 10 meshes with a gear 11. The gear 11 is rotatably installed inside the connecting member 2.

[0039] In one embodiment, for the above gear 11, the gear 11 is fixedly installed with a first rotating shaft 12. The first rotating shaft 12 is fixedly installed with a first bevel gear 13. The first bevel gear 13 meshes with a second bevel gear 14. The second bevel gear 14 is fixedly installed on a second rotating shaft 24. The second rotating shaft 24 is rotatably installed on the protruding plate 25.

[0040] In one embodiment, for the above second rotating shaft 24, the second rotating shaft 24 is fixedly installed with a protection plate 15. The protection plate 15 is made of rubber material. There are two sets of protection mechanisms, and their parts and installation methods are the same.

[0041] The working principle of a public sports fitness equipment proposed by the present invention is that when the sliding block 4 moves downward, it synchronously drives the rack 10 to move downward, driving the gear 11 to rotate, driving the first rotating shaft 12 to rotate, driving the first bevel gear 13 to rotate, driving the second bevel gear 14 to rotate, driving the second rotating shaft 24 to rotate, and driving the two protection plates 15 to swing inwardly towards each other at the same time, achieving the effect of the two protection plates 15 protecting the back of the fitness enthusiast and preventing people from falling backward during exercise.

[0042] It should be noted that when the fitness enthusiast finishes using and both feet leave the pedal 9, the two protection plates 15 will rotate in the reverse direction until they return to their original positions.

[0043] In one embodiment, for the above-mentioned connecting member 2, a limiting plate 16 is fixedly installed inside the connecting member 2, and limiting rods 17 are fixedly installed at both ends of the connecting member 2.

[0044] In one embodiment, for the above-mentioned snap mechanism, there are two sets of snap mechanisms, and their parts and installation methods are the same. The foot pedal 9 is provided with a leakage groove 18, one end of the return spring 19 is fixedly installed on the inner wall of the connecting member 2, and the other end is fixedly installed on the sliding block 4.

[0045] In one embodiment, for the above-mentioned overall bracket 1, there are two overall brackets 1, a handle 20 is fixedly installed between the two overall brackets 1, and an anti-slip sleeve 21 is fixedly installed on the handle 20.

[0046] In one embodiment, for the above-mentioned overall bracket 1, the two overall brackets 1 are fixedly installed on the bottom plate 22, and the bottom plate 22 is fixedly installed on the ground through bolts 23.

[0047] In one embodiment, for the above-mentioned overall bracket 1, the overall bracket 1, the connecting member 2, the sliding block 4, the connecting shaft 5, the connecting rod 8, and the foot pedal 9 are all made of stainless steel.

[0048] The working principle of a public sports fitness equipment proposed by the present invention is that the movement trajectory of the sliding block 4 can be limited by the limiting plate 16, and at the same time, the swing amplitude of the connecting rod 8 can be restricted by the limiting rod 17 to prevent the fitness person from swinging too high and causing danger.

[0049] It should be noted that the anti-slip sleeve 21 can increase the friction with the device when the fitness person uses it, preventing the hand from slipping and causing a forward fall.
