Description

Technical Field

[0001] The utility model relates to the technical field of bags and boxes, in particular to an assembly structure that facilitates the rapid assembly of a cover body and a box body. Background Art

[0002] The lid and case of a side-opening suitcase are directly connected via a zipper. One side of the zipper is sewn to the edge of the lid, and the other side is sewn to the opening. Because the lid is relatively flat, the zipper can be placed on a workbench and the machine sewing can be performed by rotating the lid. However, the large size of the suitcase makes it difficult to control the movement of the zipper when sewing it to the case. This results in inefficient sewing and assembly of the lid and case, impacting business profitability.

[0003] This case arises in order to solve the above problems. Utility Model Content

[0004] Therefore, in response to the above-mentioned problems, the present invention proposes an assembly structure that facilitates the rapid assembly of the cover and the box, and is used to solve the problem of low assembly efficiency of the cover and the box.

[0005] In order to solve the above technical problems, the solution adopted by the utility model is: an assembly structure that is convenient for quick assembly of a cover body and a box body, comprising a cover body and a box body, a pick-up and drop-down opening being provided on the box body, and the cover body being opened and closed by a flip-up opening, characterized in that a zipper for closing the gap or releasing the gap to control the cover body to close the pick-up and drop-down opening is provided between the periphery of the cover body and the periphery of the pick-up and drop-down opening, the inner link of the zipper is provided around and fixed on the periphery of the cover body, a rubber strip is provided around the outside of the zipper, the rubber strip is fixed on the outer link of the zipper, and a quick-install structure for quickly installing the rubber strip is provided on the front end face and / or the rear end face of the box body.

[0006] A further improvement is that the quick-loading structure includes a quick-loading groove concave inward from the end surface of the box body around the circumference of the pick-up and release opening, and the inner side wall or the outer side wall of the quick-loading groove is protruding inward and is provided with a fixing protrusion, and the fixing protrusion is provided with a fixing groove upward from the bottom surface, and the outer edge of the rubber strip is bent toward one side to form a hook portion for being clamped into the fixing groove to limit the rubber strip from detaching from the quick-loading groove.

[0007] A further improvement is that the fixing protrusions are continuously arranged around the inner side wall or the outer side wall of the quick-installation slot, or the fixing protrusions are arranged at intervals around the inner side wall or the outer side wall of the quick-installation slot.

[0008] A further improvement is that the rubber strip is fixed on the outer chain of the zipper by winding around it in one circle, or the rubber strip is fixed on the outer chain of the zipper by winding around it in sections or continuously.

[0009] A further improvement is that the outer edge of the cover is provided with an inclined surface for increasing the angle between the inner and outer link belts of the zipper to facilitate sliding of the zipper head.

[0010] A further improvement is that a bone bar is provided in the quick-release slot for fixing the external inner layer port or the external outer garment port to facilitate rapid assembly of the external inner layer or the external outer garment, and the bone bar is fixed to the bottom of the quick-release slot by the rubber strip.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] In this case, the inner link of the zipper is wrapped around and sewn to the periphery of the cover, and the outer link is sewn to the rubber strip. The outer link is fixed to the box body through the rubber strip, which improves the assembly efficiency of the cover and the box body and improves the production efficiency of the luggage.

[0013] A further beneficial effect is that the rubber strip passes through the quick-release slot, the fixed protrusion in the quick-release slot and the hook portion on the rubber strip, so that the cover can be quickly assembled on the box body without the assistance of tools, greatly improving the production efficiency of the luggage.

[0014] A further beneficial effect is that the fixing protrusions can be arranged around the side wall of the quick-release slot, or multiple fixing protrusions can be spaced apart on the side wall of the quick-release slot. A spaced-apart arrangement is preferred, which helps reduce material usage and thus lighten the weight of the bag. The openings provided at the bottom of the quick-release slot further help reduce material usage and thus lighten the weight of the bag.

[0015] A further beneficial effect is that the adhesive strip can be sewn onto the zipper in a single, continuous loop, or in multiple, spaced-apart arrangements. Regardless of the arrangement, the lid can be quickly assembled onto the case. Using a single, continuous strip facilitates quick sewing of the strip to the zipper. Using multiple, spaced-apart arrangements reduces the length of the strip and reduces the weight of the bag.

[0016] A further beneficial effect is that the inclined surface provided on the outer edge of the cover increases the angle between the inner and outer links of the zipper, making it easier for the zipper head to slide, and will not affect the use of the zipper when the cover and the box are quickly assembled.

[0017] A further beneficial effect is that the bone strip can be quickly fixed in the quick slot under the support of the rubber strip, so that when the inner layer and outer layer are added to the box body, the inner layer or outer garment can be quickly assembled to the box body through the quick assembly of the cover body and the box body, thereby improving the production efficiency of luggage.
