The inner reinforcing strip 2 is installed in the annular groove 10 by sewing. The support frame 3 can be installed in the mounting groove 20 by T-sliding or by snap-fitting onto the inner reinforcing strip 2. The zipper 4 is installed in the mounting groove 20 of the support frame 3 by sliding. While ensuring the strength of the connection between the zipper and the box body 1, the installation of the support frame 3 and the zipper 4 is convenient and the processing efficiency is improved.

[0031] To facilitate the installation of the zipper 4, preferably, the zipper 4 includes a sliding chain and a main zipper 40 and an inner zipper 41 installed on the sliding chain. The support frame 3 has a sliding ring groove 30. The sliding chain is installed in the sliding ring groove 30, and the inner zipper 41 and the main zipper 40 are located outside the sliding ring groove 30. It is not necessary to fix the zipper 4 to the box 1 by sewing. The installation of the zipper 4 can be achieved simply by installing the sliding chain in the sliding ring groove 30, which greatly reduces the labor intensity of the workers and increases the processing efficiency.

[0032] To facilitate the installation and disassembly of the sliding chain, preferably, the support frame 3 has an opening that communicates with the sliding ring groove 30, so that the sliding chain can be installed in the sliding ring groove 30 through the opening when installing the zipper 4.

[0033] Preferably, the sliding ring groove 30 has a T-shaped structure, specifically including a connecting part and a limiting part, and the limiting part is closer to the housing 1 than the connecting part, the width of the limiting part is greater than the width of the connecting part, and the sliding chain is located inside the limiting part.

[0034] Specifically, the inner zipper 41 includes an inner connecting strip 410 and inner chain teeth 411 disposed on the inner connecting strip 410. The main zipper 40 includes a main connecting strip 400 and main chain teeth 401 disposed on the main connecting strip 400. The main connecting strip 400 and the inner connecting strip 410 are connected by sewing. The sliding zipper 42 includes sliding chain teeth 421 installed on the inner connecting strip. The sliding chain teeth 421 slide within the limiting part of the sliding ring groove 30. The inner connecting strip 410 is inside the connecting part.

[0035] For ease of forming and processing of the housing 1, preferably, the opening of the annular groove 10 faces the outside of the housing 1, and the opening of the mounting groove 20 faces the outside of the housing 1.

[0036] For ease of placement of the box 1, preferably, the outer side of the support frame 3 and the outer side of the box 1 are on the same plane.

[0037] Preferably, the mounting groove 20 is a T-shaped groove, and the width of the outer side of the mounting groove 20 is smaller than the width of the inner side of the mounting groove 20. The support frame 3 has a T-shaped fastener 5, which is installed in the T-shaped groove by snapping or sliding. Specifically, the box body 1 and the inner reinforcing strip 2 have openings for placing the T-shaped fastener 5 in the mounting groove 20. The support frame 3 is installed in the mounting groove 20 by snapping or sliding. Since the mounting groove 20 is annular, and the two ends of the annular support frame 3 abut against each other to limit and fix the support frame 3.

[0038] Example 2

[0039] like Figure 3 As shown, the difference between this embodiment and the above embodiment is that: the inner zipper 41 includes an inner connecting strip 410 and inner chain teeth 411 provided on the inner connecting strip 410; the main zipper 40 includes a main connecting strip 400 and main chain teeth 401 provided on the main connecting strip 400; the sliding chain includes injection-molded teeth 420 provided on the main connecting strip 400 and the inner connecting strip 410. Specifically, the main connecting strip 400 and the inner connecting strip 410 are aligned on the side away from the chain teeth, and then... In the injection molding process, injection teeth 420 are processed on the aligned side. Multiple injection teeth 420 are provided and multiple injection pressures are distributed along the length direction of the main connecting strip 400 or the inner connecting strip 410. A deformation interval is formed between any two adjacent injection teeth 420. The injection teeth 420 are slidably installed in the sliding ring groove 30. The inner connecting strip 410 and the main connecting strip 400 are in the connection part of the sliding ring groove 30. For the convenience of installing the zipper 4, the injection teeth 420 are preferably spherical or block-shaped.

[0040] Example 3
