本设计将自行车车锁与打气筒巧妙地结合在一起，实现了二者结构形式的统一。应用双注气杆式打气结构，使打气效率优于现有的便携式打气筒，为了方便骑行者能够就地休息又附加了凳子的功能。与单独携带气筒、单独使用车锁相比，合二为一的车锁式打气筒成本低，使用、携带方便，节省空间，工作过程稳定、可靠。 The design combines a bicycle lock with a pump, realizing a uniform structure of the two. The application of a dual-pump structure makes the pumping process more efficient. In order to facilitate bicycle riders＇ relaxation, the air pump can also serve as a stool. Compared with carrying a single air pump or a single bicycle lock, this kind of air pump features lost air pumping cost, easy use, low space requirements, convenience to carry steady and reliable operation.
