TECHNICAL FIELD
[0001] The present application relates to the field of luggage, in particular to a new type of luggage mechanism. BACKGROUND
[0002] The stress of the existing luggage box is usually dependent on the strength of the box itself, and the strength of the box itself is the strength of the material of the box itself, which determines the weight that the box can bear. Especially when making some ordinary products, in order to control the cost, the material for making the box will use some ordinary materials, which will limit the strength of the box. When storing heavy objects, the outer box is easy to deform and break. CONTENT OF THE UTILITY MODEL

[0007] Optionally, it further comprises a telescopic pull rod, the telescopic pull rod is riveted to the metal frame, and the width of the inner side of the telescopic pull rod is greater than or equal to the width of the metal frame.
[0008] By adopting the above technical scheme, first, the telescopic pull rod is installed on the metal frame, which is more uniform and more firm in stress, and is convenient for pulling the box to move, second, the telescopic pull rod is installed on both sides of the outer shell, the telescopic pull rod of the traditional luggage is placed below the box, which will occupy the internal space of the box, so that the internal space of the box is irregular and affects the internal volume of the box. The both ends of the pull rod are placed on both sides of the metal frame in the present application, so that the telescopic pull rod does not occupy the internal space of the box, thereby making the internal space of the box a complete rectangular space, which can improve the internal volume of the box and facilitate the placement of objects.
[0009] Optionally, the box further comprises an inner shell, the metal frame is covered on the inner shell, and the inner shell is fixedly connected to the inner side of the metal frame.
[0010] By adopting the above technical solution, an inner shell is provided, and the metal frame is covered by the inner shell and the outer shell, reducing the possibility of the item scratching the metal frame.
[0011] Optionally, a lifting handle is fixedly connected to the upper surface of one of the metal frames.
[0012] By adopting the above technical solution, the lifting handle is installed on the metal frame, which will distribute the force evenly when lifting and make it more secure.
[0013] Optionally, one of the metal frames is fixedly connected to a side handle on the side away from the hinge end.
[0014] By adopting the above technical solution, a side handle is provided, which allows the suitcase to be lifted from the side. The side handle is set on the metal frame, so when lifting the suitcase, the metal frame bears most of the weight, making the force distribution more even and more secure.
[0015] Optionally, the bottom of the metal frame is fixedly connected with casters.
[0016] By adopting the above technical solution, casters are installed at the bottom of the metal frame to facilitate the movement of the suitcase.
[0017] Optionally, a pad is provided on the side of the outer shell near the hinge point of the metal frame. Two pads are provided, and the two pads are distributed along the length direction of the outer shell.
[0018] By adopting the above technical solution, when the box needs to be laid on its side, the box is supported by pads, and the pads replace the box in contact with the supporting surface, thereby reducing the possibility of wear and tear on the box.
[0019] Optionally, the pad is elastically configured, and the cross-sectional area of the pad gradually decreases in the direction away from the metal frame.
[0020] Optionally, the middle part of the telescopic rod is bent and protrudes away from the housing to form a grip.
[0021] By adopting the above technical solution, a grip is provided on the telescopic rod, which makes it easy for the user's hand to pass through the gap between the grip and the outer shell and pull the telescopic rod.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. This application uses a metal frame for support, which greatly improves the load-bearing capacity of the suitcase, provides a stress benchmark for other components, and reduces the problem of uneven stress causing the suitcase to break when loaded with excessively heavy items;
[0024] 2. First, the telescopic pull rod is installed on the metal frame, the force is more uniform, more firm, and it is convenient to pull the box to move, second, the telescopic pull rod is installed on both sides of the shell, the telescopic pull rod of the traditional luggage is placed below the box, which occupies the internal space of the box, so that the internal space of the box is irregular and affects the internal volume of the box, and the both ends of the pull rod are placed on both sides of the metal frame, so that the telescopic pull rod does not occupy the internal space of the box, thereby making the internal space of the box a complete rectangular space, which can improve the internal volume of the box and facilitate the placement of articles.
