It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a category and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents a "or" relationship between the front and rear associated objects.

[0038] The main rubber frame for luggage provided by the embodiments of the present application will be described in detail below in combination with the drawings, through specific embodiments and application scenarios.

[0039] Embodiment 1:

[0040] The embodiments of the present application provide a main rubber frame for luggage, which comprises a frame body 1, a lining 2 and a mounting assembly one 6, the mounting assembly one 6 comprises a mounting groove one 61 and an insertion strip 62, wherein the mounting groove one 61 is arranged on the frame body 1, and the insertion strip 62 is fixedly arranged on the outer edge of the lining 2, and the lining 2 is fixed on the frame body 1 by the insertion of the insertion strip 62 and the mounting groove one 61.

[0041] As Figure 3As shown in the figure, due to the adoption of the above structure, the insert strip 62 is a rectangular plate structure, which is fixed to the outer edge of the lining 2 by sewing or gluing. When installing, align the insert strip 62 with the first installation groove 61 and push the insert strip 62 horizontally. After it is completely inserted, it is snap-fitted and fixed with the first installation groove 61 to complete the installation of the lining 2. When disassembling, pull the insert strip 62 outward with fingers to make the insert strip 62 disengage from the first installation groove 61, and then the lining 2 can be taken out. Compared with the prior art, the edge of the lining 2 only needs to be laid flat on the surface of the insert strip 62 for sewing, with a simple structure, low manufacturing cost and low difficulty.

[0042] The glue frame body 1 is U-shaped, and at the top of the end facing the inside of the box shell 11, there is a reinforcing structure 12 with a "mouth" - shaped cross-section. The first installation groove 61 is arranged inside the glue frame body 1, close to the reinforcing structure 12.

[0043] Embodiment 2:

[0044] The difference from Embodiment 1 is that in this embodiment of the present application, the first installation component 6 further includes fixing strips 65 and clamping strips 63 respectively provided on the adjacent side walls of the first installation groove 61 and the insert strip 62. When the insert strip is inserted into the first installation groove 61, the fixing strip 65 and the clamping strip 63 are mutually buckled.

[0045] In this embodiment of the present application, a guiding surface 66 is provided on the clamping strip 63 or the fixing strip 65, which is used to guide the clamping strip 63 to slide into the inside of the fixing strip 65 during the process of inserting the insert strip 62 into the first installation groove 61. Buckling surfaces 67 are provided on both the clamping strip 63 and the fixing strip 65, which are used to buckle the clamping strip 63 and the fixing strip 65.

[0046] In this embodiment of the present application, the first installation component 6 further includes a pulling plate 64 fixedly arranged at the outer end of the insert strip 62.

[0047] In this embodiment of the present application, the lower end of the pulling plate 64 extends downward to the lower part of the first installation groove 61, and the included angle with the insert strip 62 is 90 - 135°.

[0048] Such as Figure 3As shown, due to the adoption of the above structure, the pair of clamping strips 63 are respectively located at the top surface outer end of the mounting groove one 61 and the bottom surface of the insertion strip 62. During installation, the insertion strip 62 is aligned with the mounting groove one 61, and is pushed into the insertion strip 62 along the horizontal direction. The guide surface 66 on the clamping strip 63 or the fixed strip 65 is inclined, contacts and presses the fixed strip 65 or the clamping strip 63, so that the outer end of the mounting groove one 61 is elastically deformed and the width is increased. After the insertion strip 62 is completely inserted into the mounting groove one 61, the clamping strip 63 moves to the inner side of the fixed strip 65, and the mounting groove one 61 restores under the self-elasticity. The two buckling surfaces 67 on the clamping strip 63 and the fixed strip 65 are buckled with each other. The fixed strip 65 and the mounting groove one 61 are made of rubber material and have elasticity. When disassembling, the finger pulls the pull plate 64 outward, the two buckling surfaces 67 are pressed with each other, the lower part of the mounting groove one 61 is bent and deformed, the outer end is deformed and increased, until the two buckling surfaces 67 are separated from each other, the fixed strip 65 is separated from the clamping strip 63, and the insertion strip 62 can be pulled out from the mounting groove one 61, and the disassembly of the inner lining 2 is completed.

[0049] As shown in Figures 1 to 3 When the included angle between the pull plate 64 and the insertion strip 62 is 90°, the lower end of the insertion strip 62 does not protrude outside the reinforcing structure 12, which ensures the aesthetics and facilitates the finger to pull. When the finger pulls the pull plate 64, the length of the force arm is suitable for the angle of the human finger holding, the operating force is directly transmitted to the insertion strip 62 through the pull plate 64, and the tearing risk caused by the traditional direct pulling of the inner lining 2 is avoided. The setting of the pull plate 64 avoids the damage risk caused by the direct pulling of the inner lining 2, and is especially suitable for the light inner lining 2 material (such as non-woven fabric), and improves the reliability of the connecting structure.

[0050] When the included angle between the pull plate 64 and the insertion strip 62 is 135°, the lower end of the insertion strip 62 protrudes outside the reinforcing structure 12, and people can pinch the insertion strip 62 with two fingers and pull the pull plate 64, avoiding the tearing risk caused by the traditional direct pulling of the inner lining 2. The setting of the pull plate 64 avoids the damage risk caused by the direct pulling of the inner lining 2, and is especially suitable for the light inner lining 2 material (such as non-woven fabric), and improves the reliability of the connecting structure.
