Abstract
Description
[Technical Field]
[0001] This utility model relates to a zipper mounting structure for a trolley case. [Background Technology]
[0002] A rolling suitcase consists of a front shell and a rear shell. The rear shell is usually where the rolling handle is mounted. The openings of the front and rear shells close together to form the suitcase body. To ensure closure between the front and rear shells, a zipper is installed. The most traditional method for installing the zipper is to sew it directly with stitching, but this method has low durability. Later, a method using adhesive strips for installation emerged. These strips are bonded to the front and rear shells using heat pressing. However, heat pressing requires both heating and cooling, which is time-consuming and inefficient. [Utility Model Content]

Detailed Implementation Methods
[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:
[0016] Example 1, as Figure 1As shown, a zipper mounting structure for a trolley case that is easy to install includes a front shell 1 and a rear shell 2. The openings of the front shell 1 and the rear shell 2 are joined together to form a box shape, and only a partial cross-section is shown in the figure. A front plastic frame 3 is provided on the edge of the opening of the front shell 1, and a rear plastic frame 4 is provided on the edge of the rear shell 2 opposite to the front shell 1. The front plastic frame 3 and the rear plastic frame 4 are ring-shaped. A first connecting piece 5 is provided on the front shell 1 to secure the front plastic frame 3, and a second connecting piece 6 is provided on the rear shell 2 to secure the rear plastic frame 4. The first connecting piece 5 and the second connecting piece 6 are rivets, respectively. The front plastic frame 3 is secured to the front shell 1 and the rear plastic frame 4 is secured to the rear shell 2 by riveting. The installation can be quickly completed by riveting with a riveting machine. The front housing 1 and the rear housing 2 have multiple first riveting holes 12 along their length. These first riveting holes 12 are evenly distributed around the opening edges of the front housing 1 and the rear housing 2. The front plastic frame 3 and the rear plastic frame 4 have multiple second riveting holes 34 along their length, each communicating with one of the first riveting holes 12. Rivets pass through the first riveting holes 12 and the second riveting holes 34 to rivet the front housing 1 and the front plastic frame 3, or the rear housing 2 and the rear plastic frame 4. One end of the rivet has a large end 56 that abuts against the end face of the front plastic frame 3 or the rear plastic frame 4 and has an outer diameter larger than that of the second riveting hole 34. The other end of the rivet has a retaining ring 57 that can be fastened to the end face of the front housing 1 or the rear housing 2. The retaining ring 57 has an approximately hook-shaped cross-section and an arc-shaped guide surface 58 that can be squeezed and guided by the first riveting holes 12 and the second riveting holes 34. The front plastic frame 3 is provided with a first zipper slot 31, and the rear plastic frame 4 is provided with a second zipper slot 41. The front plastic frame 3 and the rear plastic frame 4 are connected by an outer zipper 7. The two ends of the outer zipper 7 are respectively inserted into the first zipper slot 31 and the second zipper slot 41. The two ends of the outer zipper 7 are provided with protrusions, which are square protrusions in the figure. The square protrusions are squeezed into the first zipper slot 31 and the second zipper slot 41.
[0017] To accommodate the inner layer of the box, the front plastic frame 3 has a first inner zipper slot 35 on one end of the inner side of the box. The first inner zipper slot 35 engages with a first inner zipper 36, which is half of a zipper. The other half of the zipper is fixed to the edge of the inner layer. Since the inner layer is usually made of fabric, it can be secured directly by stitching. The rear plastic frame 4 has a second inner zipper slot 45 on one end of the inner side of the box. The second inner zipper slot 45 engages with a second inner zipper 46, which has the same configuration as the first inner zipper 36. Both the second inner zipper 46 and the first inner zipper 36 can be size 5 zippers, and the outer zipper 7 can be size 8 to 10 zippers.
[0018] Example 2, as Figure 2As shown, the difference from Embodiment 1 lies in the different structures of the first connector 5 and the second connector 6. Specifically, the first connector 5 is a first plastic strip that abuts against the end face of the front housing 1 and protrudes. The first plastic strip can be fixed to the front housing 1 by stitching. Because the shape of the first plastic strip is simple, the stitching does not require much technical skill, and the stitching is firm and convenient. The first plastic strip is provided with a first buckle 51, and the front plastic frame 3 is provided with a first hook 32 that abuts against the first buckle 51. The front plastic frame 3 is provided with a first snap groove 33 with one end open towards the front housing 1. The first hook 32 is located at the opening edge of the first buckle groove 33. One end of the front housing 1 with the first plastic strip is inserted into the first buckle groove 33. When the front housing 1 is inserted into the first buckle groove 33, the first hook 32 is pressed against the end face of the first plastic strip. The end faces of the first plastic strip and the front housing 1 are respectively attached to the two opposite faces of the first buckle groove 33. The combined height of the first plastic strip and the front housing 1 is greater than the width of the opening of the first buckle groove 33 where the first hook 32 is located. The end face of the first plastic strip away from the first buckle edge 51 is provided with a first inclined guide surface 52 for the first hook 32 to press and guide. The second connector 6 is a second plastic strip that abuts against the end face of the rear housing 2 and protrudes. The second plastic strip has a second fastening edge 61. The rear plastic frame 4 has a second hook 42 that abuts against the second fastening edge 61. The rear plastic frame 4 has a second snap-fit groove 43 with one end open towards the rear housing 2. The second hook 42 is located at the opening edge of the second snap-fit groove 43. The end of the rear housing 2 with the second plastic strip is inserted into the second snap-fit groove 43. When the rear housing 2 is inserted into the second snap-fit groove 43, the second hook 42 and the second plastic strip are pressed together. The end face of the second plastic strip away from the second fastening edge 61 has a second inclined guide surface 62 for guiding the pressing of the second hook 42. The installation method of the second plastic strip is the same as that of the first plastic strip, and the design of the second snap-fit groove 43 is also the same.
