Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of woven bags, in particular to a woven bag with high structural strength. Background Art
[0002] Woven bags are widely used in various fields, such as agriculture, industry, tourism and transportation. Some of the larger woven bags are often used to package chemical raw materials, grain starch, cement sand, etc. for transportation. These large woven bags are also called "ton bags". These large woven bags usually have multiple handles. When transporting between warehouses and containers, these woven bags are usually carried by forklifts passing through the handles. Since the space inside these woven bags is large, the items contained are also very large and heavy. Therefore, once the structural strength between the handle and the bag body is insufficient, the handle or the bag body will be torn, causing the items contained to fall. In view of this, the present application further improves the structural strength between the handle and the bag body on these woven bags. Utility Model Content

DETAILED DESCRIPTION
[0022] The following will be combined with the attached embodiment of the present utility model Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Example:
[0024] like Figures 1 to 5 As shown, the utility model discloses a woven bag with high structural strength, including a bag body in a cubic shape with a bag opening facing upward, the bag body including an outer bag body 1 and an inner bag body 2, the inner bag body 2 is sewn to the inner side of the outer bag body 1, and handles 3 are provided on the four vertices on the upper side of the outer bag body 1, and fixing belts 4 are integrally formed on both ends of the handles 3, the fixing belts 4 are fixedly sewn on the inner side wall of the outer bag body 1, and a belt threading port 5 for the handles 3 to pass through the inner side of the outer bag body 1 to the outside is opened on the outer bag body 1. It should be noted that the fixing belts 4 on the two ends of each handle 3 are respectively located on two adjacent side walls of the outer bag body 1, and as shown in FIG. Figure 3 As shown, an inward folded piece 6 is provided on the upper side of the outer bag body 1 and is folded toward its inner side wall and covers the upper side of the fixing belt 4 . The inward folded piece 6 is sewn to the fixing belt 4 and the outer bag body 1 .
[0025] like Figure 3 and Figure 5 As shown, a crisscross-shaped bottom reinforcement belt 7 is sewn on the inner side of the bottom surface of the outer bag body 1, wherein the fixing belt 4 extends to the inner bottom of the outer bag body 1 and is fixedly connected to the bottom reinforcement belt 7. The provision of the bottom reinforcement belt 7 can not only improve the structural strength of the fixing belt 4 but also improve the structural strength of the bottom of the outer bag body 1.
[0026] Furthermore, a middle loop band 8 is sewn in a ring shape on the middle part of the inner wall of the outer bag body 1, and the middle loop band 8 contacts the fixing band 4 and is sewn therewith. The middle loop band 8 improves the structural strength of the side wall of the outer bag body 1, and also improves the structural strength of the fixing band 4 sewn to the outer bag body 1.
[0027] It should be noted that the inner bag body 2 covers the fixing belt 4, the bottom reinforcement belt 7 and the middle loop belt 8, that is, the fixing belt 4, the bottom reinforcement belt 7 and the middle loop belt 8 are located between the outer bag body 1 and the inner bag body 2, which can prevent the fixing belt 4, the bottom reinforcement belt 7 and the middle loop belt 8 from being worn by the installed items, thereby improving the service life.
[0028] In addition, Figure 1 and Figure 2 As shown, a first reinforcing belt 9 and a second reinforcing belt 10 are sewn on the outer side wall of the outer bag body 1. The first reinforcing belt 9 goes to the upper end of the front side of the outer bag body 1, goes around the bottom of the outer bag body 1 downward, and then extends upward to the upper end of the rear side of the outer bag body 1, while the second reinforcing belt 10 goes to the upper end of the left side of the outer bag body 1, goes around the bottom of the outer bag body 1 downward, and then extends upward to the upper end of the right side of the outer bag body 1. The arrangement of the first reinforcing belt 9 and the second reinforcing belt 10 can effectively support the bottom center of the bag body, make up for the bottom center of the bag body missed by the tic-tac-toe-shaped bottom reinforcing belt 7, thereby further strengthening the structural strength of the utility model.
[0029] Furthermore, an outer ring band 11 is sewn in a ring shape on the middle part of the outer side wall of the outer bag body 1, and the outer ring band 11 contacts and is sewn with the first reinforcement band 9 and the second reinforcement band 10. The outer ring band 11 can further improve the structural strength of the side wall of the bag body and improve the firmness of the sewing of the first reinforcement band 9 and the second reinforcement band 10.
[0030] In addition, in the present invention, a wear-resistant layer 12 is sewn on the inner side of the handle 3, and the wear-resistant layer 12 is made of nylon material.
