The tube body is locked. A folding frame for a bicycle according to the present invention includes a tubular body and a safety lock device. The tubular body comprises a first segment, a second segment and a pivoting device, and the central pivoting device is disposed between the first segment and the second segment. The safety lock device can be disposed on the tubular body adjacent to the splicing device and includes a body, a movable lock member, an elastic member, and a fixed lock member. This system is combined with the first paragraph. The movable lock member is movably disposed on the body and has a hook portion extending in the direction of the tubular body. The elastic member is disposed on the body and has a first end fixed to the body and a second end connected to the movable lock member to provide a resilient force of the movable lock member. The fixed lock member is disposed on the second segment and corresponds to the hook portion. The hook portion is snapped to the fixed lock member by the return elastic force. A safety lock device according to the present invention is for a folding tube body mounted on a folding bicycle, the folding tube body comprising a first pivoting section and a second section, the safety locking device comprising a body , movable lock components, elastic components and fixed lock components. This system is intended to be combined with the first paragraph. The movable locking element is movably disposed on the body and has a hook portion. The elastic member is disposed between the body and the movable lock member to provide a resilience of the movable member. A fixed lock element is provided on the second segment and corresponds to the hook. The hook portion is snapped to the lock element by the return elastic force. 7 1320018 In an embodiment, the hook portion has a leading edge, such as a beveled leading edge β. When the safety locking device is engaged, if the tubular body can be in a deployed position (ie, in an unfolded state), the body is pushed toward the tube. After the guiding edge of the movable locking element contacts the fixed locking element, the pushing body continues to push the guiding edge of the movable locking element and the fixed locking element to move relative to the body, and the elastic element is elongated to generate a resilient force. Until the fixed lock element slides out of the leading edge, the resilient resilient force of the resilient element pulls back (ie, reversely) the movable locking element such that the hook portion of the 'tongue lock element' is automatically snapped onto the fixed lock element. Since the elastic member is disposed between the body and the movable lock member, when the hook portion is buckled to the fixed lock member, the hook portion is not disengaged by the fixed lock member, so that the safety lock device connects the first segment of the tubular body with the first The second section securely locks the positioning to ensure that there is no detachment or relative displacement between the first and second segments when the bicycle is riding. In addition, the safety lock device is easy to operate, and can be locked or unlocked with one hand, which is quite convenient in use. At the same time, the body of the safety lock device can hide the movable lock component, the elastic component and the fixed lock component, etc., so that the whole is quite beautiful, and the accidental touch can be avoided.
