AI Technical Summary
The gap between the front cover and the body of the existing suitcase is uneven, which affects the appearance and makes assembly difficult.
The system employs a combination of inserts and guides. After the insert is inserted into the guide, it determines the relative position of the front cover and the housing, ensuring uniform gaps.
It achieves uniform adjustment and positioning of the gap between the front cover and the box body, improving assembly accuracy and aesthetics.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of luggage technology, and in particular relates to a lid and a luggage. Background Technology
[0002] People who frequently travel for business may need to frequently take out and put away items during their trips, so they tend to place frequently used items in the front of their suitcases where they can easily reach them.
[0003] Based on this, existing suitcase designs feature an openable front cover that is connected to the suitcase body via a hinge, allowing users to easily open the front cover to retrieve items. However, this hinge structure design requires careful assembly; otherwise, it is easy to find uneven gaps between the front cover and the suitcase body after assembly. Furthermore, after a period of use, uneven gaps often become apparent at the joint between the front cover and the suitcase body, affecting the appearance. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a front cover positioning mechanism that can ensure a uniform gap between the front cover and the box body after the front cover is fastened.
[0005] A front cover positioning mechanism includes an insert disposed on the front cover / box and a guide disposed on the box / front cover. After the insert is inserted into the guide, the position of the front cover relative to the box is determined, thereby ensuring that the gap between the front cover and the box is uniform.
[0006] Furthermore, the inserts and guides are arranged in groups on the front cover and the housing, with no fewer than two groups.
[0007] Furthermore, the guide is provided with a guide surface for guiding the insertion of the insert, and the insert is provided with a cutting surface that mates with the guide surface. After the cutting surface and the guide surface are fully fitted, the relative positions of the front cover and the box are completely determined and the gap between them remains uniform.
[0008] Furthermore, the guide member is provided with several guide surfaces, and the insert member is provided with several cutting surfaces that mate with the guide surfaces;
[0009] Furthermore, the guide is a conical hole, and the insert is a conical protrusion;
[0010] Furthermore, the guide is a triangular groove, and the insert is a triangular protrusion;
[0011] Furthermore, the guide is a hemispherical groove, and the insert is a ball head with a diameter smaller than that of the hemispherical groove;
[0012] Compared with the prior art, this utility model can adjust and position the gap between the lid and the box body after the lid is fastened, ensuring that the gap between the lid and the box body is uniform. Attached Figure Description
[0013] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0020] Example 1
[0021] Please refer to Figures 1-2 The diagram shows a front cover positioning mechanism for positioning the cover frame of the front cover of a suitcase and the inner frame on the suitcase body. It includes several triangular protrusions (i.e., inserts 1a) on the inner frame of the suitcase body and triangular grooves (i.e., guides 2a) on the cover frame of the front cover that correspond one-to-one with the triangular protrusions. The inner frame 1 and the cover frame 2 are connected by a hinge 3.
[0022] Guide member 2a1 is disposed on cover frame 2, and has three guide surfaces, namely Figure 2 The surfaces shown are 2a-1, 2a-2, and 2a-3; the insert 1a also has three corresponding cutting surfaces, namely... Figure 2 As shown in 1a-1, 1a-2, and 1a-3, during the process of inserting the triangular protrusion (i.e., insert 1a) into the triangular groove (i.e., guide 2a), it will inevitably contact one or more of the guide surfaces first, until all the guide surfaces and the cutting surfaces are in contact, thus achieving the positioning between the front cover and the box body and ensuring that the gap between the two is uniform.
[0023] Example 2
[0024] See Figure 3 Compared to Embodiment 1, the main difference lies in the shapes of the insert and guide. This embodiment uses a conical hole as the guide and a conical protrusion as the insert. In this design, the apex angle of the conical protrusion is the same as the apex angle of the conical hole.
[0025] Example 3
[0026] See Figure 4 Compared to Embodiment 1, the main difference lies in the shapes of the insert and guide. In this embodiment, a hemispherical groove is used as the guide, and a ball head with a diameter smaller than that of the hemispherical groove is used as the insert.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
