Description

Technical Field

[0001] The utility model relates to the technical field of bicycle tire loading machines, in particular to an automatic bicycle tire loading machine. Background Art

[0002] In the bicycle manufacturing and maintenance industry, tire installation is an indispensable link. Traditional bicycle tire installation methods mainly rely on manual operation, which takes a lot of time and manpower. Especially during the assembly process of the tire and the hub, workers need to manually adjust the tire position to ensure that it is correctly installed on the hub. This process is not only cumbersome but also inefficient. In addition, when manually installing the tire, workers need to press the tire hard, which may cause hand injuries or other safety issues.

[0003] In order to achieve the effect of efficient assembly, at present, a mechanized bicycle tire automatic tire-loading machine is usually used to perform tire assembly operations. For example, the utility model patent with authorization announcement number CN212289408U discloses a bicycle tire-loading machine, which belongs to the technical field of tire installation equipment. The key points of its technical solution are that it includes a frame, a mounting plate is rotatably provided on the top surface of the frame, a driving member for driving the mounting plate to rotate is provided under the mounting plate, a fixing assembly for fixing the wheel is provided at the center of the mounting plate, a fixing rod is provided on one side of the frame, and a tire-loading assembly is provided on the fixing rod, and the tire-loading assembly includes a clamping plate fixed on the fixing rod, a pressure wheel and a guide wheel rotatably connected to the fixing rod, the clamping plate is pressed on the outer tire and the wheel hub, the pressure wheel is pressed on the side of the outer tire close to the wheel hub, and the guide wheel is pressed on the side of the outer tire away from the wheel hub, so as to achieve the effect of automatically installing the outer tire and avoiding damage to the inner tire by using tools.

[0004] Although this technical solution has advantages such as avoiding the use of tools and damaging the inner tube, when it is used, there is a large distance between the mounting plate and the frame, and the mounting plate is directly fixed on the output shaft of the motor. Since the tire needs to be squeezed downward during installation, the squeezing force will directly act on the mounting plate, and the force on the mounting plate will further directly act on the output shaft of the motor. At this time, this type of mounting plate lacks other components that can support and share the squeezing force, which can easily cause a large pressure to squeeze the output shaft of the motor and damage the output shaft, affecting the service life and normal use of the motor and causing inconvenience to the user. In view of this, we propose an automatic bicycle tire loading machine. Utility Model Content
