DETAILED DESCRIPTION

[0030] The advantages and features of the present invention will become more apparent from the following description and claims.

[0031] Example 1

[0032] See Figure 1 、 Figure 2 and Figure 4 In one embodiment, a bag includes a middle frame structure, which includes a middle frame body 1, a lining layer 3 and at least one embracing body 2.

[0033] The middle frame body 1 is extended with an embracing wall 102 and a limiting wall 101 spaced apart in the horizontal direction. A first groove is formed between the embracing wall 102 and the limiting wall 101. A first locking protrusion 103 is provided on the side of the embracing wall 102 away from the limiting wall 101.

[0034] A limiting member 4 is provided on the lining layer 3 and is configured to be arranged in the first groove (the limiting member 4 may be a steel wire, which is passed through the edge of the lining layer 3).

[0035] The embracing body 2 includes an insert wall 201 and an extension wall. The insert wall 201 and the extension wall cooperate to form an embracing groove, and a second engaging protrusion 205 is provided on the side of the extension wall facing the insert wall 201. The embracing groove is configured to embracingly engage with the embracing wall 102. The insert wall 201 is inserted into the first groove and cooperates with the embracing wall 102, the limiting wall 101, and the middle frame body 1 to form a limiting chamber 5 for constraining the limiting member 4. Furthermore, the extension wall is arranged on the side of the embracing wall 102 facing away from the limiting wall 101, and the second engaging protrusion 205 engages with the first engaging protrusion 103. (The middle frame body 1 is typically a closed-loop structure approximately rectangular, and multiple embracing bodies 2 can be spaced apart on the middle frame body 1.)

[0036] In this embodiment, a middle frame body 1, a lining layer 3 and an embracing body 2 are provided. An embracing wall 102 and a limiting wall 101 are provided on the middle frame body 1, and a first groove is formed between the two. The embracing wall 102 is provided with a first buckling protrusion 103, and a limiting member 4 for embedding into the first groove is provided on the lining layer 3. The embracing body 2 is provided with an inserting wall 201 and an extending wall. The extending wall is provided with a second buckling protrusion 205. The inserting wall 201 is used to be inserted into the first groove, and the extending wall is used to When fitted to the side of the embracing wall 102 facing away from the limiting wall 101, the two can cooperate and combine with the first locking protrusion 103 and the second locking protrusion 205 to achieve the fixing of the relative position of the embracing body 2 with respect to the embracing wall 102, and the insertion wall 201 is inserted into the first groove to form a limiting chamber 5 for limiting the limiting member 4 on the lining layer 3, and the limiting member 4 will not fall out, thereby achieving the fixation between the lining layer 3 and the middle frame body 1, solving the problem that the existing lining can only be connected to the middle frame in an irremovable manner.

[0037] The specific structure of the middle frame structure of the luggage in this embodiment is further described below:

[0038] In this embodiment, the difference between the horizontal width of the above-mentioned first groove and the horizontal width of the above-mentioned insertion wall 201 is smaller than the protrusion size of the first snap-fit ​​protrusion 103 in the horizontal direction, and the difference between the horizontal width of the first groove and the horizontal width of the insertion wall 201 is smaller than the maximum width of the limit member 4 in the horizontal direction.

[0039] The difference between the horizontal width of the first groove and the horizontal width of the insert wall 201 is set to be smaller than the horizontal projection size of the first snap-fitting protrusion 103, so that after the first snap-fitting protrusion 103 and the second snap-fitting protrusion 205 are snapped together, the embracing body 2 is restrained and will not separate from the middle frame body 1; and the difference between the horizontal width of the first groove and the horizontal width of the insert wall 201 is set to be smaller than the maximum horizontal width of the limiting member 4, so that after the limiting chamber 5 is formed in the first groove, the limiting member 4 therein will not escape from the gap between the insert wall 201 and the first groove, thereby further ensuring the stability of the fixation between the lining layer 3 and the middle frame body 1.

[0040] In this embodiment, the first engaging protrusion 103 includes a first engaging surface facing the middle frame body 1, and the second engaging protrusion 205 includes a second engaging surface facing away from the middle frame body 1, with the first engaging surface and the second engaging surface matching each other. Both the first and second engaging surfaces are horizontal, ensuring a full fit during engagement and improving engagement stability.

[0041] Furthermore, the side of the first engaging protrusion 103 facing away from the middle frame body 1 serves as a first guiding slope, while the side of the second engaging protrusion 205 facing toward the middle shell body serves as a second guiding slope. The first guiding slope matches the second guiding slope. Furthermore, both the first and second guiding slopes are inclined toward the middle frame body 1, along the direction of the embracing wall 102 away from the limiting wall 101. This serves as a slope to guide the second engaging protrusion 205 upward over the first engaging protrusion 103, facilitating insertion.

[0042] In this embodiment, the first locking protrusion 103 can be arranged to be located at the bottom end of the embracing wall 102, that is, the first locking protrusion 103 can be arranged in the middle position in the height direction of the embracing wall 102, so that the length of the embracing wall 102 inserted into the second groove formed by the insertion wall 201 and the extension wall can be further lengthened, thereby improving the stability of the embracing, making it difficult for the embracing body 2 to separate from the middle frame body 1.

[0043] In this embodiment, the aforementioned extension walls may specifically include a horizontal transition wall 202 , an oblique transition wall 203 , and a vertical transition wall 204 .

[0044] The horizontal ends of the horizontal transition wall 202 are connected to the bottom end of the insertion wall 201 and the first end of the oblique transition wall 203 in the horizontal direction, respectively. The second end of the oblique transition wall 203 in the horizontal direction is connected to the bottom end of the vertical transition wall 204. The second snap-fitting protrusion 205 is provided on the side of the vertical transition wall 204 facing the insertion wall 201. The locations where the oblique transition wall 203 connects to the horizontal transition wall 202 and the vertical transition wall 204 can be rounded. The arrangement of the oblique transition wall 203 and the vertical transition wall 204 is mainly to match the arrangement of the first snap-fitting protrusion 103 avoiding the bottom end of the embracing wall 102. That is, after the oblique transition wall 203 and the vertical transition wall 204 are provided, the installation position of the second snap-fitting protrusion 205 can be further raised, thereby matching the height of the first snap-fitting protrusion 103.

[0045] In this embodiment, a guiding slope is provided on the side of the bottom end of the limiting wall 101 facing the embracing wall 102 , for cooperating with the guiding insertion wall 201 to be inserted into the first groove.

[0046] In this embodiment, in order to ensure that the snap-fitting body can be smoothly snapped into the middle frame body 1 and is not easy to fall out after snapping, the ratio of the difference between the horizontal width of the first groove and the horizontal width of the insertion wall 201 to the horizontal width of the first groove is A, 0.1≤A≤0.2.

[0047] Furthermore, in order to match the actual size of a bag, the difference between the horizontal width of the first groove and the horizontal width of the insertion wall 201 is B, and 0.3 mm ≤ B ≤ 0.6 mm.

[0048] In this embodiment, the material of the buckling body can be plastic or other materials with sufficient strength and certain deformation ability.
