[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0022] Reference Figure 1 , Figure 2 and Figure 3As shown, the utility model provides a technical solution: a chain disk fixing seat of a children's bicycle comprises a frame 1, mounting rods 2 are rotatably connected to both sides of the frame 1, a chain disk 3 is rotatably connected to the surface of the mounting rod 2, a mounting disk 4 is installed on the side of the chain disk 3 away from the frame 1, a rotating disk 5 is rotatably connected to the inside of the mounting disk 4, a first transmission rod 7 is slidably connected to the inside of the rotating disk 5, a clamping block 8 is fixedly connected to one side of the first transmission rod 7, a second transmission rod 10 is fixedly connected to one end of the rotating disk 5, a mounting groove 11 is provided at one end of the second transmission rod 10, control blocks 17 are slidably connected to both sides of the mounting groove 11, a fixing block 18 is fixedly connected to the bottom end of the control block 17, a first protective plate 9 is installed at one end of the mounting rod 2, a through groove 19 is provided on the surface of the first protective plate 9, and fixing grooves 20 are provided at both ends of the through groove 19, a second protective plate 13 is fixedly connected to the other end of the mounting rod 2, a plurality of first clamping blocks 12 are fixedly connected to one end of the first protective plate 9, and a plurality of first clamping blocks 13 are fixedly connected to the first protective plate 9. The second protective plate 13 is fixedly connected to one end with a plurality of second clamping blocks 14, and a clamping groove 15 is provided inside the second clamping block 14. By pressing the control block 17, the second transmission rod 10 is slid into the through groove 19 on the surface of the mounting rod 2, and then the second transmission rod 10 is pulled to make the second transmission rod 10 drive the rotating disk 5 to rotate, and the guide groove 6 on the surface of the rotating disk 5 drives the first transmission rod 7 to move. The movement of the first transmission rod 7 drives the clamping block 8 to clamp the inside of the first protective plate 9, and then the pressure on the control block 17 is released, so that the control block 17 drives the fixing block 18 to enter the inside of the fixing groove 20, thereby completing the installation of the first protective plate 9. By installing the first protective plate 9, we can effectively protect the chain plate 3, thereby significantly improving the durability of the chain plate 3. During riding, the possibility of the chain plate 3 being hit and worn by external objects will be greatly reduced. This protective measure not only extends the service life of the chain plate 3, but also ensures the safety and smoothness of riding.
[0023] Reference Figure 4 and Figure 5 As shown, in the present embodiment: a plurality of guide grooves 6 are opened inside the rotating disk 5, and the guide grooves 6 are distributed circumferentially. The inner wall of the guide groove 6 is slidably connected to the surface of the first transmission rod 7. By setting the guide groove 6, a guiding effect can be played on the moving trajectory of the first transmission rod 7. By avoiding the jamming phenomenon during the rotation of the rotating disk 5, the fixing and locking effect of the first protective plate 9 is improved.
[0024] Reference Figure 2 As shown, in this embodiment: one end of the first transmission rod 7 is fixedly connected to the limiting block 16 , and by providing the limiting block 16 , the first transmission rod 7 can be prevented from being separated from the inside of the guide groove 6 .
[0025] Reference Figure 4As shown, in this embodiment: a clamping pad 23 is fixedly connected to the inner side of the clamping block 8, and the material of the clamping pad 23 is rubber. By providing the clamping pad 23 and utilizing the rubber material of the clamping pad 23, the friction between the clamping block 8 and the first protective plate 9 can be increased, making the fixation more stable.
[0026] Reference Figure 3 As shown, in this embodiment: one end of the second transmission rod 10 is fixedly connected to a fixing plate 24, both ends of the fixing plate 24 are fixedly connected to springs 25, and the other end of the spring 25 is fixedly connected to the control block 17. By setting the spring 25, the elasticity of the spring 25 can abut against the control block 17, so that the control block 17 will not easily fall off from the inside of the fixing groove 20, thereby improving the overall stability.
[0027] Reference Figure 6 As shown, in this embodiment: first sliding grooves 21 are opened on both sides of the installation groove 11, one end of the first transmission rod 7 is fixedly connected to the first slider 22, the interior of the first sliding groove 21 is slidably connected to the first slider 22, and by making the first slider 22 slide inside the first sliding groove 21, the movement of the control block 17 can be more stable without shaking.
[0028] Reference Figure 3 As shown, in this embodiment: the outer diameter of the fixing block 18 and the inner diameter of the fixing groove 20 are adapted to each other. By making the outer diameter of the fixing block 18 and the inner diameter of the control block 17 adapted to each other, the fixation between the two can be made more stable. This precise matching not only improves the reliability of the connection, but also ensures that there will be no loosening or falling off during use.
[0029] Working principle: by pressing the control block 17, the second transmission rod 10 is slid into the through groove 19 on the surface of the mounting rod 2, and then the second transmission rod 10 is pulled to make the second transmission rod 10 drive the rotating disk 5 to rotate, and the guide groove 6 on the surface of the rotating disk 5 drives the first transmission rod 7 to move, and the movement of the first transmission rod 7 drives the clamping block 8 to clamp the inside of the first protective plate 9, and then release the pressure on the control block 17, so that the control block 17 drives the fixing block 18 to enter the inside of the fixing groove 20, thereby completing the installation of the first protective plate 9. By installing the first protective plate 9, we can effectively protect the chain plate 3, thereby significantly improving the durability of the chain plate 3. During riding, the possibility of the chain plate 3 being hit and worn by external objects will be greatly reduced. This protection measure not only extends the service life of the chain plate 3, but also ensures the safety and smoothness of riding. By setting the guide groove 6, the moving trajectory of the first transmission rod 7 can be guided. In the process of rotating the rotating disk 5, the jamming phenomenon is avoided and the fixing and locking effect of the first protective plate 9 is improved. By setting the limit block 16, the first transmission rod 7 can be prevented from disengaging from the inside of the guide groove 6. The material of the clamping pad 23 is rubber. By setting the clamping pad 23 and utilizing the rubber material of the clamping pad 23, the friction between the clamping block 8 and the first protective plate 9 can be increased, making the fixation more stable. By setting the spring 25, the elasticity of the spring 25 can be made to abut against the control block 17, so that the control block 17 will not easily fall off from the inside of the fixing groove 20, thereby improving the overall stability. By making the first slider 22 slide inside the first slide groove 21, the movement of the control block 17 can be made more stable and no shaking will occur. By making the outer diameter of the fixing block 18 and the inner diameter of the control block 17 adapt to each other, the fixation between the two can be made more stable. This precise matching not only improves the reliability of the connection, but also ensures that there will be no loosening or falling off during use.
