[0002] A fitness bike is one of the indoor fitness equipment. It mainly promotes cardiovascular movement through proper-intensity exercise for a long time, speeds up metabolism, enhances heart and lung functions, and thus improves the physical fitness of the human body.

[0003] When a traditional fitness bike is in use, the foot pedals are axially rotated by the feet, the sprockets are axially rotated by the foot pedals, and the driven wheels are axially rotated by the sprockets through the chain, so as to achieve the exercise purpose. Under the long-term exercise of the user, the physical strength will decline to a certain extent. When the feet slip on the foot pedals when driving the foot pedals to rotate, the feet will exert a certain extrusion on the middle part of the sealing plate on one side of the chain case, thereby deforming the sealing plate under force. When the sealing plate is under excessive force, since there is no certain component force to support the middle part of the sealing plate, the sealing plate is damaged, reducing the service life of the sealing plate. In view of the above situation, we propose a chain cover for a fitness bike. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a chain cover for a fitness bike to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: A chain cover for a fitness bike, comprising:

[0017] The technical effects and advantages of the present utility model:

[0018] (1) The present utility model uses the design of the buffer assembly to provide a certain component force support for the sealing plate, which is composed of the fixing base, the honeycomb air cushion and the guide sliding rod cooperating with each other. The honeycomb air cushion has a plurality of honeycomb air cavities inside, and the honeycomb air cushion is made of a rubber material with a certain elasticity. Therefore, the honeycomb air cushion can separate the force received by the sealing plate and can also reset the sealing plate.

[0019] (2) When the sealing plate is subjected to an extrusion force in the present utility model, the sealing plate exerts an extrusion force on the positioning plate and the bearing plate, the bearing plate exerts an extrusion force on the corrugated soft plate, causing the corrugated soft plate to contract under force. At the same time, the positioning plate exerts an extrusion force on the guide sliding rod, the guide sliding rod exerts an extrusion force on the honeycomb air cushion, and the honeycomb air cushion is deformed under the extrusion force, causing the honeycomb grooves inside it to be deformed. Therefore, the extrusion force received is separated and offset by the plurality of honeycomb grooves inside it, and then the force received in the middle of the sealing plate is separated and offset. When the force received by the honeycomb air cushion reaches its own limit, it starts to rebound, pushing the guide sliding rod to slide along the inside of the guide sliding cavity. Then, the guide sliding rod drives the positioning plate, the bearing plate and the corrugated soft plate to be reset, and then drives the sealing plate to be reset. Description of the drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a chain cover for a fitness bike as Figures 1-4 shown, including:

[0027] A chain cover housing 1 for isolating and protecting the chain of the fitness bike;

[0028] A sealing plate 2 fixedly arranged at the top of the chain cover housing 1 for sealing and protecting the chain cover housing 1. Multiple installation grooves are provided on the side of the top of the chain cover housing 1. Multiple mounting blocks 201 are respectively fixedly connected to both sides of the sealing plate 2. The mounting blocks 201 are sleeved inside the installation grooves. Through the mutual cooperation of the mounting blocks 201 and the installation grooves, the position of the sealing plate 2 is limited;

[0029] A positioning plate 3 arranged inside the chain cover housing 1. A bearing plate 4 is fixedly inserted and connected to the bottom of the positioning plate 3 for limiting the position of the sealing plate 2 and driving the sealing plate 2 to reset. The top of the positioning plate 3 is slidably inserted into the inside of the sealing plate 2, and the top end of the bearing plate 4 is in mutual contact with the bottom end of the sealing plate 2;

[0030] A corrugated flexible plate 5 is fixedly connected to the bottom of the inner wall of the chain guard housing 1. The top end of the corrugated flexible plate 5 is fixedly connected to the bottom end of the bearing plate 4. The corrugated flexible plate 5 can seal between the inner wall of the chain guard housing 1 and the positioning plate 3;

[0031] A fixing plate 7 is attached to the top end of the sealing plate 2. A fixing bolt 8 is slidably inserted through the interior of the fixing plate 7. The bottom end of the fixing bolt 8 is threadedly inserted into the interior of the positioning plate 3;

[0032] Buffer components, there are multiple of them, which are respectively arranged inside the chain guard housing 1. The top ends of the buffer components are fixedly connected to the bottom end of the positioning plate 3 and are used to buffer and protect the middle part of the sealing plate 2. They are composed of a fixed base 6, a honeycomb air cushion 602 and a guiding slide bar 601. The interior of the honeycomb air cushion 602 has multiple honeycomb air cavities. The honeycomb air cushion 602 is made of a rubber material with a certain elasticity. Thus, the honeycomb air cushion 602 can separate the force received by the sealing plate 2 and can also reset the sealing plate 2;

[0033] The buffer component includes a fixed base 6, a honeycomb air cushion 602 and a guiding slide bar 601. The bottom end of the fixed base 6 is fixedly connected to the bottom of the inner wall of the chain guard housing 1. The honeycomb air cushion 602 is fixedly arranged inside the fixed base 6. The guiding slide bar 601 is slidably inserted through the top end of the fixed base 6. The top end of the guiding slide bar 601 is fixedly connected to the bottom end of the sealing plate 2. A guiding slide cavity for the guiding slide bar 601 to slide is formed inside the fixed base 6, and the bottom of the inner wall of the guiding slide cavity is fixedly connected to the bottom end of the honeycomb air cushion 602. When a certain extrusion force is applied to the middle part of the sealing plate 2, the sealing plate 2 exerts an extrusion force on the positioning plate 3 and the bearing plate 4. The bearing plate 4 exerts an extrusion force on the corrugated flexible plate 5, causing the corrugated flexible plate 5 to contract under force. At the same time, the positioning plate 3 exerts an extrusion force on the guiding slide bar 601, and the guiding slide bar 601 exerts an extrusion force on the honeycomb air cushion 602. The honeycomb air cushion 602 is deformed by the extrusion force, causing the honeycomb grooves inside it to be deformed. Thus, the extrusion force received is separated and offset by the multiple honeycomb grooves inside it, and then the force received by the middle part of the sealing plate 2 is separated and offset. When the force received by the honeycomb air cushion 602 reaches its own limit, it starts to rebound, pushing the guiding slide bar 601 to slide along the inside of the guiding slide cavity. Then the guiding slide bar 601 drives the positioning plate 3, the bearing plate 4 and the corrugated flexible plate 5 to reset, and then drives the sealing plate 2 to reset;

[0034] Limit chute grooves are provided on both sides of the guiding sliding cavity. A limit sliding block 603 is slidably sleeved inside the limit chute groove. The opposite ends of the two limit sliding blocks 603 are fixedly connected to both sides of the bottom of the guiding sliding rod 601. The bottom end of the limit sliding block 603 is fixedly connected with a return spring 604. The bottom end of the return spring 604 is fixedly connected to the bottom of the inner wall of the limit chute groove. When the guiding sliding rod 601 is subjected to an extrusion force, the guiding sliding rod 601 drives the limit sliding block 603 to exert an extrusion force on the return spring 604, thereby further dispersing the extrusion force generated by the guiding sliding rod 601. When the extrusion force generated by the guiding sliding rod 601 on the honeycomb air cushion 602 reaches the limit, the return spring 604 drives the guiding sliding rod 601 to reset through the limit sliding block 603, and then limits the position of the guiding sliding rod 601 through the limit sliding block 603, preventing the sealing plate 2 from separating from the inside of the chain cover housing 1, and ensuring that the bottom end of the mounting block 201 and the bottom of the inner wall of the mounting groove are always in a mutually fitting state.

[0035] The working principle of the present utility model:

[0036] Refer to Appendix Figure 1 to Appendix Figure 4 The operator first sleeved the chain cover housing 1 outside the fitness bike sprocket and chain, then fixed the chain cover housing 1 on the fitness bike. Then, hold the sealing plate 2 by hand, and then snap the sealing plate 2 into the inside of the chain cover housing 1, so that the mounting block 201 is snapped into the mounting groove, and the positioning plate 3 is snapped into the middle of the sealing plate 2. The top end of the bearing plate 4 and the bottom end of the sealing plate 2 are mutually attached. Then, hold the fixing plate 7 by hand, and then align the through hole on the fixing plate 7 with the internal thread groove on the positioning plate 3. Then, hold the fixing bolt 8 by hand, and then pass one end of the fixing bolt 8 through the through hole and thread it into the inside of the positioning plate 3;

[0037] When a certain extrusion force is applied to the middle of the sealing plate 2, the sealing plate 2 exerts extrusion on the positioning plate 3 and the bearing plate 4. The bearing plate 4 exerts an extrusion force on the corrugated flexible plate 5, causing the corrugated flexible plate 5 to contract under force. At the same time, the positioning plate 3 exerts an extrusion force on the guiding sliding rod 601, and the guiding sliding rod 601 exerts an extrusion force on the honeycomb air cushion 602. The honeycomb air cushion 602 is deformed under extrusion, causing the honeycomb grooves inside it to be deformed, and then separating and offsetting the extrusion force received through the multiple honeycomb grooves inside it, thereby separating and offsetting the force received in the middle of the sealing plate 2. When the force received by the honeycomb air cushion 602 reaches its own limit, it starts to rebound, pushing the guiding sliding rod 601 to slide along the inside of the guiding sliding cavity. Then, the guiding sliding rod 601 drives the positioning plate 3, the bearing plate 4 and the corrugated flexible plate 5 to reset, and then drives the sealing plate 2 to reset;

[0038] Meanwhile, the guiding slide bar 601 drives the limiting slider 603 to generate an extrusion force on the return spring 604, thereby further dispersing the extrusion force generated by the guiding slide bar 601. When the extrusion force generated by the guiding slide bar 601 on the honeycomb air cushion 602 reaches the limit, the return spring 604 drives the guiding slide bar 601 to reset through the limiting slider 603, and then limits the position of the guiding slide bar 601 through the limiting slider 603, preventing the sealing plate 2 from detaching from the inside of the chain cover housing 1, and ensuring that the bottom end of the mounting block 201 and the bottom of the inner wall of the mounting groove are always in a mutually attached state.
