Definitions

  • the invention relates to a folding fastening device for a folding bicycle. Background technique
  • the front and rear frames can be fastened together to prevent looseness during transportation and to facilitate storage.
  • Most folding bicycles are equipped with folding fastening devices.
  • the existing folding fastening devices have two structures.
  • the utility model is composed of an elastic clip and a ball head that is compatible with the size of the elastic clip.
  • the elastic clip and the ball head are respectively fixed at the corresponding positions of the front and rear frames of the folding bicycle.
  • the front and rear frames of the folded bicycle are fastened together.
  • the folded bicycle is opened, the front and rear frames of the folded bicycle are opened, and the ball head is squeezed out of the elastic clip, thereby unlocking the folding fastening device.
  • the structure of the folding and fastening device is convenient to use, but the material used to make the elastic clip must have good toughness.
  • the material used to make the ball joint should be wear-resistant and costly. After long-term use, the elastic clip will deform and gradually fail, and During the manufacturing process, the relative position of the elastic clamp and the ball head is high, the allowable tolerance is small, and the manufacturing cost is high.
  • the folding fastening device of another structure includes a connecting plate, as shown in FIG. 2, one end of the connecting plate is hinged with the front or rear frame of the folding bicycle, and the other end is notched, which can be clamped and fixed on the folding bicycle. After folding the fixing post on the other frame, the slot of the connecting plate is clamped to the fixing post after the bicycle is folded, so as to fasten the front and rear frames of the folding bicycle together.
  • the accuracy of the relative position of the notch of the connection plate and the fixed column is still high, the process is difficult, and the user must first remove the connection plate from the fixed column before opening the folding bicycle. Inconvenient to use. Summary of the Invention
  • the purpose of the present invention is to provide a fastening device for a folding bicycle, which is convenient to install and has low cost, and can be automatically opened when the folding bicycle is opened.
  • the fastening device of the folding bicycle according to the present invention is installed at the corresponding position of the front frame and the rear frame of the folding bicycle, a magnet is installed at the front frame or the rear frame of the folding bicycle, and the corresponding position of the other frame A magnetic object can be attached to the magnet.
  • magnets and magnetic objects are installed at the corresponding positions of the front and rear frames of the folding bicycle.
  • the fastening device of this structure has low requirements on the dimensional fit between the magnet and the magnetic object, and reduces the difficulty of the process.
