Description

Technical Field

[0001] This utility model relates to a luggage structure, and more particularly to a suitcase that is easy to assemble. Background Technology

[0002] As a storage tool, a suitcase can be used to store daily necessities and school supplies when traveling, making it convenient to carry. The bottom of a suitcase usually has a positioning component and wheels mounted on the positioning component. The positioning component is installed at the bottom of the suitcase, and by setting up the wheels, the suitcase can be pulled by a lever, reducing the load and improving the portability of the suitcase.

[0003] For the installation of positioning components on traditional suitcases, multiple screws (at least five screws) are usually used to fix the positioning components to the suitcase shell. Accordingly, multiple holes need to be machined in the positioning components and the shell to accommodate the screws. Because multiple holes need to be machined in the positioning components and the shell, the processing complexity and cost of the positioning components and the shell are increased. Moreover, the assembly efficiency is low, which causes trouble for manufacturers. Utility Model Content

[0004] Therefore, it is necessary to provide a suitcase that is easy to assemble, addressing the shortcomings of existing technologies.

[0005] An easy-to-assemble suitcase includes a suitcase body, several positioning components, and several casters. Each caster includes a wheel body and a connecting frame connected to the wheel body. The suitcase body includes a shell with a positioning hole at the bottom corner. Each positioning component includes an inner cover, a wheel seat, and a locking element. The inner cover has a pin, and the wheel seat has a positioning groove. During assembly, the inner cover passes through the positioning hole from the inside of the shell and is locked in place at the opening of the positioning hole. The wheel seat is installed on the inner cover from the outside of the shell. The pin is inserted into the positioning groove. The upper end of the connecting frame of the caster is inserted into the wheel seat. The locking element passes through the inner cover and extends into the wheel seat to cooperate with the connecting frame.

[0006] In one embodiment, the inner cover further includes a first shell body, the pin is connected to the first shell body, the first shell body is a semi-closed shell structure, and the edge of the first shell body is provided with a retaining edge. During assembly, the retaining edge of the inner cover is engaged with the opening inside the positioning hole.

[0007] In one embodiment, the bottom of the first shell body is provided with a first mating groove, the top of the first shell body is provided with a mating surface, and the pin is connected to the side wall of the first mating groove in a horizontal direction, with the mating surface and the pin being parallel to each other.

[0008] In one embodiment, the inner cover has a snap groove behind the mating surface, the snap groove is connected to the first mating groove, the mating surface has two grooves extending to the snap groove, and the mating surface between the two grooves forms a spring piece. The wheel seat includes a second shell body, a locking block connected to the inner side of the second shell body, and a buckle connected to the locking block. During installation, the buckle extends into the snap groove position and is locked onto the spring piece in the horizontal direction.

[0009] In one embodiment, the mating surface is provided with a connecting hole, which communicates with the first mating groove. The wheel seat also includes a connecting post vertically connected to the bottom of the second shell body. The wheel seat is also provided with a locking hole and a stop piece. The locking hole passes through the locking block and the connecting post in a vertical direction. The stop piece is connected to the hole wall of the locking hole. The upper end of the pulley's connecting frame is inserted into the locking hole from below the connecting post and abuts against the stop piece. The locking member is a screw, which passes through the connecting hole and the stop piece of the inner cover and is installed on the connecting frame.

[0010] In one embodiment, the card block is fitted with the mating surface.

[0011] In one embodiment, the second shell body is configured as a semi-closed shell structure, a second mating groove is formed on the inner side of the second shell body, the locking block is connected to the groove wall of the second mating groove, and the positioning groove extends horizontally inward from the outer side of the locking block.

[0012] In one embodiment, the connection position between the buckle and the card block is located above the positioning groove opening.

[0013] The advantages of this modular suitcase are as follows: By setting an inner cover, wheel seats, and locking components on the positioning assembly, and providing a pin on the inner cover and a positioning groove on the wheel seats, during assembly, the inner cover passes through the inside of the suitcase shell and is secured to it.
