The invention discloses an automatic safety locking device of a connecting rod type folding box. The connecting rod type folding box comprises a first connecting plate and a second connecting plate which are hinged to each other, a handle is hinged to the other side of the first connecting plate, a connecting rod is hinged to the other side of the second connecting plate, the connecting rod is hinged to the other end of the handle, a groove is formed in the side face of the handle, a button is inserted in the groove and located on the outer side face of the handle, a compression spring is installed on the tail portion of the button so that the button can slide along the outer surface of the handle in the groove of the handle, a touch hook installed on the inner side of the handle is fixedly connected with the button, a guide touch hook base matched with the touch hook is arranged on a hinged base of the second connecting plate connected to the connecting rod, and when the connecting rod type folding box is folded, the touch hook is clamped into the guide touch hook base. When the folding box is locked with the device, the automatic safety locking device can safely, reliably and automatically prevent a connector from being opened accidentally.
Description
technical field [0001] The invention relates to an automatic locking device for a link type folding box, in particular to an automatic safety locking device for folding a vertical tube of a bicycle and a folding box of a vehicle beam. Background technique [0002] Existing folding bicycle adopts connecting rod type folding box more. Because of the link type folding box, the operation is simple and the locking is reliable. After the existing link type folding box is locked, in order to prevent accidental opening, a safety hook is arranged at the end of the handle mostly to catch the handle. After the folding box is locked, pull the safety hook by hand to catch the handle. If the user forgets to fasten the safety hook, it will bring certain safety hazards to the user. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a link type folding box automatic safety locking device with simple structure, convenient operatio...
