Description

Technical Field

[0001] The utility model relates to a bicycle, in particular to a fixing structure of a bicycle accessory which can be installed at the front of the bicycle and can be easily disassembled and fixed. Background Art

[0002] The existing bicycles usually have only one seat, that is, they are used by one person and are driven forward by pedaling. There are few places for passengers or accessories. During riding, if there is a need to carry infants or young children or to add accessories for long-distance replenishment or physiological status monitoring, an additional baby seat or accessory is usually installed on the frame of the bicycle. The conventional baby seat is designed with a structure that is combined with the frame of the bicycle. The baby seat is pre-combined with the frame with a fixing device, and then the baby seat is installed on the fixing device so that the baby seat can be combined with the bicycle. The common fixing device is mostly combined with the top tube or seat tube of the bicycle. In addition, when the fixing device is installed on the top tube or seat tube, a rubber sleeve is provided between the fixing device and the tube body of the top tube or seat tube. A buffer can be formed between the fixing device and the tube body and a tightening effect can be increased, and the fixing device can strengthen the combination effect between the baby seat and the tube body through the rubber sleeve; in addition, the accessories of the bicycle will be installed on the tube body, such as installing a shelf on the seat tube, or installing a water bottle holder or a computer holder on the handlebar.

[0003] When the existing child seat is combined with the frame through the fixing device, although the space for carrying the baby can be increased, when it is installed on the upper tube or the seat tube, it is closer to the user's body, making it inconvenient for the user to ride and use it. In addition, when it is placed on the upper tube, it is closer to the user's body and is more likely to cause interference during riding, resulting in inconvenience in riding. In addition, if it is set on the seat tube, although it does not affect riding, it will place the infant behind the user, making it more difficult to pay attention to the infant's situation in real time during riding. In addition, the fixing device and the rubber sleeve are rotatable. When the friction between the two is insufficient or the tightness is insufficient, the fixing device will easily rotate relative to the rubber sleeve or the tube body, causing the baby seat to be easily shaken or pushed by external force after installation, so that the baby seat is not fixed in the same position; when installing accessories, it is also easy to cause insufficient number of installations due to the small installation range, resulting in the inability to place the required items on the bicycle completely, causing inconvenience in use.
