Description

Technical Field

[0001] The utility model relates to the technical field of fixing footrest straps of child safety seats for bicycles, in particular to a fixing device for fixing footrest straps of child safety seats for bicycles. Background Art

[0002] A child seat is a seat that is attached to a vehicle for a child to sit on and has a restraining device to ensure the child's safety. Nowadays, parents like to take their children to public green spaces for leisure and to enjoy nature in the suburbs. Many people like to ride or push bicycles, so it is also very common to install a child seat on a bicycle.

[0003] The adjustable pedal and foot buckle with patent number CN207153007U are provided with a first adjustment structure and a second adjustment structure on the pedal body; the first limit plate and the second limit plate are respectively perpendicular to the pedal body, and are arranged parallel to the center line of the pedal body along the direction of foot extension; a first bolt rod is provided at one end of the first limit plate, the first bolt rod passes through the first adjustment structure, and cooperates with the first nut to fix the first limit plate on the pedal body; a second bolt rod is provided at one end of the second limit plate, the second bolt rod passes through the second adjustment structure, and cooperates with the second nut to fix the second limit plate on the pedal body.

[0004] However, research has shown that the existing bicycle child safety seat footrest strap fixing device still has the following defects:

[0005] The existing child safety seat for bicycles is generally fixed to the rear seat of the bicycle by bolts. When the pedal of the safety seat is used, the child's feet need to be placed on the pedal first, and then one end of the strap is passed through the back of the foot, and then the length of the strap is adjusted and locked using a locking device. When adjusting, the strap needs to be pulled so that the strap is close to the back of the foot, so that the child's feet are limited on the pedal, thereby preventing the child's feet from falling off the pedal. However, when the child gets off the bicycle, the strap needs to be loosened again, which results in the need to adjust and lock the strap again each time it is used. When encountering some situations where time is needed, the above cumbersome steps still need to be repeated, and the child's feet cannot be fixed on the pedal in a short time, thereby wasting time. At the same time, the shape of the general pedal is fixed, but the size of the child's feet is different. When the child's feet are too large, they cannot be placed on the pedal as a whole, resulting in a lack of support for the child's feet, affecting the comfort of the child's feet. Therefore, it is necessary to optimize a foot strap fixing device for a child safety seat for bicycles through technical innovation and design optimization. Utility Model Content

[0006] The existing footrest straps for children's safety seats on bicycles generally use a locking device to lock the child's feet on the pedals. This results in the need to readjust the straps every time they are used, which takes a relatively long time to bind the child's feet. To solve the above problems, the embodiments of the present application provide a fixing device for the footrest straps of a children's safety seat on a bicycle. Through the mutual cooperation of the limiting mechanism and the limiting part, the first pedal can stop at the place where it needs to stop, avoiding the step of frequent adjustment, thereby completing the function of adjusting and limiting the distance between the first pedal and the second pedal. At the same time, by sliding the first pedal, the restraint strap can be driven to quickly bind the feet. At the same time, the first pedal can stop at the previously adjusted pressing groove position, facilitating the quick binding of feet of different lengths.

[0007] The technical solution adopted by the embodiments of the present application to solve its technical problems is:

[0008] A fixing device for the footrest straps of a children's safety seat on a bicycle, comprising:

Detailed implementation manner

[0028] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. Additionally, the forms of each structure recorded in the following implementation manners are merely examples, and the instrument placement rack related to the present utility model is not limited to the structures recorded in the following implementation manners. All other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0029] This embodiment introduces the specific structure of a footrest strap fixing device for a children's safety seat on a bicycle, specifically referring to Figures 1 - 7 As shown, a footrest strap fixing device for a children's safety seat on a bicycle includes:

[0030] Pedal one 1, there is a pedal two 5 on one side of pedal one 1, a leg support plate 4 is fixed on the top of pedal two 5, a plug board 10 is fixed on the side of pedal one 1 facing pedal two 5, a slot 11 is opened on the side of pedal two 5 facing pedal one 1, a plurality of pressing grooves 26 are opened on pedal two 5, the pressing grooves 26 communicate with the slot 11, a pressing block 17 is arranged in the pressing groove 26, a limiting mechanism capable of limiting the pressing block 17 is arranged inside the pressing block 17, a limiting portion capable of inserting into the inside of the pressing groove 26 is arranged on the plug board 10, a restraint strap 3 is fixed on one side of the top of pedal one 1, and a lock 8 capable of locking the restraint strap 3 is arranged on the other side of pedal one 1.

[0031] The length of a general pedal is integrally cast and non-adjustable, and the position of the restraint strap 3 is also fixed. When the child's feet are too small or too large, the restraint strap 3 cannot effectively limit the child's feet.

[0032] When it is necessary to adjust the distance between the first pedal 1 and the second pedal 5, the limiting mechanism includes a groove 25 opened in the pressing groove 26. A rotating groove 23 for accommodating the rotation of the limiting rod 18 is opened inside the pressing block 17. The limiting rod 18 is arranged inside the rotating groove 23. A rotating column 24 is fixed on the limiting rod 18. The rotating column 24 penetrates through the pressing block 17 and is fixed with a rotating plate 21. By rotating the rotating plate 21, the rotating plate 21 drives the rotating column 24 to rotate. The rotating column 24 drives the limiting rod 18 to rotate inside the rotating groove 23. When the limiting rod 18 rotates into the groove 25, the pressing block 17 can be limited to prevent the pressing block 17 from moving inside the pressing groove 26.

[0033] When it is necessary to wear the restraint strap 3, the limiting part includes a limiting groove 12 opened on the insertion plate 10. A limiting block 14 that can be inserted into the inside of the pressing groove 26 is arranged inside the limiting groove 12. A spring 13 is arranged inside the limiting groove 12. The spring 13 is fixedly connected to the limiting block 14 and the pressing block 17. The spring 13 is in a compressed state. Under the action of the spring 13, the limiting block 14 will slide inside the limiting groove 12 and insert into the inside of the pressing groove 26.

[0034] If the limiting block 14 is not provided with an inclined surface, due to the gap between the pressing groove 26 and the pressing block 17, the limiting block 14 is likely to be blocked by the gap during movement, making it difficult to move the limiting block 14.

[0035] In addition, one end of the limiting block 14 away from the spring 13 is provided with an inclined surface, and the inclined surface faces the second pedal 5. After the pressing block 17 pushes the limiting block 14 out of the pressing groove 26, when pulling the insertion plate 10, the limiting block 14 will not be blocked by the gap between the pressing groove 26 and the pressing block 17.

[0036] When encountering a bumpy road section, the rotating plate 21 may rotate by itself, which will cause the limiting rod 18 to rotate out of the groove 25, resulting in the inability to limit the pressing block 17.

[0037] It should be noted that a first magnet 19 and a third magnet 22 are fixed on the pressing block 17, and a second magnet 20 is fixed on the rotating plate 21. The first magnet 19, the third magnet 22 and the second magnet 20 can attract each other to prevent the rotating plate 21 from rotating by itself when encountering a bumpy road section.

[0038] In addition, a soft pad 2 is fixed on the restraint strap 3 to prevent the restraint strap 3 from causing harm to the child's foot.

[0039] Since there is no support at the bottom of the first pedal 1, the insertion plate 10 may be subjected to excessive force and break during long-term sliding.

[0040] When the first pedal 1 and the second pedal 5 move, a first fixed block 9 is fixed to the bottom of the first pedal 1, and a second fixed block 7 is fixed to the bottom of the second pedal 5. A guide plate 6 is fixed to the first fixed block 9. The guide plate 6 passes through the second fixed block 7. A baffle 27 is fixed to the guide plate 6. The guide plate 6 can slide in the second fixed block 7 to facilitate the support of the first pedal 1 and the second pedal 5, and the baffle 27 can prevent the first pedal 1 and the second pedal 5 from falling off.

[0041] The pressing groove 26 has no blocking mechanism, which may cause the pressing block 17 to fall off from the pressing groove 26.

[0042] When the pressing block 17 slides, sliding grooves 15 are formed on both inner sides of the pressing groove 26. Sliding blocks 16 are arranged in the sliding grooves 15. The sliding blocks 16 are fixedly connected to the pressing block 17. The pressing block 17 will drive the pressing block 17 to move in the pressing groove 26, preventing the pressing block 17 from falling off from the pressing groove 26, and at the same time improving the stability of the pressing block 17 moving inside the pressing groove 26.

[0043] First, place the child's feet on the first pedal 1 and the second pedal 5. Since the pressing block 17 is not limited, while pulling the first pedal 1, press the pressing block 17 one by one to push the limiting block 14 out of the pressing groove 26, facilitating the pulling of the plug board 10. When the child's feet can be fully placed on the pedals, at this time, the pressing block 17 pushed out of the pressing groove 26 remains stationary, and the remaining pressing columns are all limited inside the pressing groove 26 through the limiting mechanism. Then, pass the restraint belt 3 through the buckle 8 to lock the restraint belt 3, thereby completing the function of adjusting the distance between the first pedal 1 and the second pedal 5, facilitating the placement of feet of different lengths.

[0044] After the adjustment is completed, press the fixed block of the non-limiting block 14 to push the limiting block 14 inside the pressing groove 26 out of the pressing groove 26. Since the other pressing blocks 17 are all limited, the limiting block 14 cannot be inserted into the other pressing grooves 26. At this time, pull the first pedal 1 until the baffle 27 contacts the second fixed block 7. Place the child's feet on the first pedal 1 and the second pedal 5, and push the first pedal 1 to stop at the set position. At this time, the restraint belt 3 can just restrain the child's feet, and the rapid restraint of the child's feet is completed in sequence.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
