Among them, the first frame and the second frame can be meshed with each other to form a closed frame structure, and the first frame and the second frame can be selected according to the market positioning or functional requirements of the luggage product. The first frame and the second frame are required to have a groove width that can accommodate the material thickness of the corresponding lock part and the box shell at the same time, so that the first lock part and the second lock part can be completely built into the corresponding frame grooves to form a split-type built-in lock structure, thereby achieving a greater degree of maintaining the overall aesthetics of the luggage, and not affecting the normal locking and unlocking functions of the luggage.
[0005] The first lock part is an integrated structure, including a first lock part body, a lock hook and a first mounting part. The first mounting parts are respectively provided at both ends of the first lock part body. The first mounting parts are locked and connected with the inner side of the first frame by screws. The first lock part body is provided with a lock hook on the side facing the second lock part. In this structure, the first lock part body and the first mounting part serve as the base of the first lock part, and are hidden in the first frame after installation. The lock hook is used to cooperate with the second lock part to realize the function of locking or unlocking, and the lock hook is exposed outside the first frame in the direction toward the second frame.
[0006] The second lock part includes a second lock part body, a slider, a spring and a push button. The second lock part body has a cavity with an opening on one side. The slider is installed in the cavity. The push button is closely arranged on the outer side of the second frame. The push button passes through the second frame and is fixedly connected to the slider. A spring is arranged on one side of the slider. A lock hole is arranged on the side of the second lock part body facing the first lock part. In this structure, the second lock part body serves as the mounting base of the entire second lock part. After being mounted on the second frame through the second mounting part described below, the second lock part body (including the slider, spring and the gasket arranged inside it) are all hidden in the second frame. The position of the lock hole on the second lock part body corresponds to the lock hook in the first lock part, so that the lock hook can enter and exit the second lock part.
[0007] In the second locking part, second mounting parts are respectively provided at both ends of the second locking part body, and the second mounting parts are locked and connected with the inner side of the second frame by screws.
[0008] In the second lock part, a connection column is provided on one side of the push button, and a mounting hole is correspondingly provided on the slider. The connection column on the push button passes through the outer side of the second frame and is then locked and fixed with the mounting hole on the slider by screws.
