Abstract
Description
[Technical Field]
[0001] This utility model mainly relates to a luggage base structure. [Background Technology]
[0002] In current suitcase designs, handles are generally located on the top of the suitcase, while there are usually no handles on the bottom. This is mainly to facilitate dragging and moving. However, when climbing stairs, it is necessary to lift the suitcase. In this case, you can only grab it from the top handle and lift it vertically. Since the suitcase is generally long, the vertical lifting space is limited, which is very inconvenient. Therefore, a horizontal lifting method is also used. However, since there are no handles on the bottom of the suitcase, when lifting it horizontally, you can only support the end of the suitcase. The end of the suitcase is generally designed with a curved shape, which makes it easy to slip and lose your grip, making it difficult to lift. [Utility Model Content]
[0003] To solve the problem of luggage being lifted horizontally, this utility model proposes a new structural solution. The luggage base structure of this utility model adopts the following technical solution:
[0004] A luggage base structure includes a suitcase body and a handle, wherein the bottom of the suitcase body has a recessed cavity and a protrusion extending inward from the recessed cavity;
[0005] The grip is an integral structure, including a curved cover, a baffle and a locking pin. The baffle and locking pin are located on the inside of the curved cover, and the locking pin is located on the baffle. The grip abuts against the boss through the baffle to limit the position of the grip installed in the cavity.
[0006] Preferably, the top of the cavity has a recess for the bent cap to abut against.
[0007] Preferably, the width of the grip is less than the height of the cavity.
[0008] Preferably, the end of the bent cap extends into a support edge, which is arranged parallel to the baffle.
[0009] Preferably, the cavity is provided with a connecting hole, and the locking pin is connected to the connecting hole and locked with screws to secure the grip to the housing.
[0010] The beneficial effects of this utility model compared with the prior art are:
[0011] To facilitate horizontal lifting of the suitcase, this design incorporates a recessed cavity at the bottom of the suitcase body, within which grips are installed. The grips are positioned within the cavity by a curved cap engaging with the recess and a baffle engaging with the protrusion, and are secured to the suitcase body with screws connecting to locking posts. The width of the grips is less than the height of the recess, creating a semi-open state and allowing space for fingers to be inserted. By grasping the pull rods at both ends of the suitcase and the grips, the suitcase can be lifted horizontally, eliminating the slippage problem associated with traditional methods of supporting the suitcase by its ends, making it more convenient to use. It boasts advantages such as simple structure, compact fit, and rational design; therefore, it is a product with superior technical and economic performance. [Attached Image Description]

Detailed Implementation Methods
[0015] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0017] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0018] The preferred embodiment provided by this utility model is as follows: Figures 1-3As shown, a suitcase bottom support structure includes a suitcase body 1 and a handle 2. The top of the suitcase body is provided with a telescopic pull rod, which is an existing structure and will not be described in detail here. The bottom of the suitcase body 1 is provided with a cavity 11, and a boss 12 extends inward from the cavity 11. The boss 12 is located on both sides of the cavity 11. The width of the handle 2 is less than the height of the cavity 11 to leave space for fingers to be inserted into the cavity 11.
[0019] The grip 2 is an integral structure, comprising a curved cover 21, a baffle 22, and a locking pin 23. The baffle 22 and the locking pin 23 are located inside the curved cover 21, and the locking pin 23 is located on the baffle 22. The grip 2 abuts against the boss 12 via the baffle 22 to restrict the position of the grip 2 in the cavity 11. The top of the cavity 11 has a recess 13 for the curved cover 21 to abut against. The position of the grip 2 is thus limited by the abutment between the curved cover 21 and the recess 13, and the abutment between the baffle 22 and the boss 12.
[0020] The end of the curved cover 21 extends into a support edge 24 for easy gripping, and the support edge 24 is parallel to the baffle 22. The cavity 11 is provided with a receiving hole 14, and the locking pin 23 is aligned with the receiving hole 14. The locking pin 23 is provided with a corresponding screw hole. The screw passes through the receiving hole 14 inside the housing 1 and is connected to the locking pin 23, thereby fastening the grip 2 to the housing 1.
[0021] To facilitate horizontal lifting of the suitcase, a recessed cavity 11 is added to the bottom of the suitcase body 1, and a grip 2 is installed in the recessed cavity 11. The grip 2 is fixed in the position of the recessed cavity 11 by the bent cover 21 abutting against the recessed position 13 and the baffle 22 abutting against the boss 12. It is fixed to the suitcase body 1 by screw connecting to the locking post 23. The width of the grip 2 is less than the height of the recessed cavity 11, so that the recessed cavity 11 is in a semi-open state, leaving space for fingers to insert into the recessed cavity 11. At this time, by grasping the pull rods at both ends of the suitcase body 1 and the grip 2, the suitcase body 1 can be lifted horizontally, which solves the slippage problem of the traditional method of supporting the end face of the suitcase body 1, making it more convenient to use.
[0022] In the description of this specification, references to terms such as "an embodiment," "preferred," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model.
