Abstract
Description
Technical Field
[0001] This utility model relates to woven bags, and more particularly to a woven bag with self-supporting capabilities. Background Technology
[0002] Woven bags are flexible packaging containers made of woven plastic flat yarns. They are lightweight, durable, and low-cost, and are therefore widely used in agriculture, industry, construction, logistics and other fields. However, because woven bags are made of flexible material and are mostly used for filling granular materials, they are prone to tipping over and leaking when users open them to take out materials, as the bottom of the woven bag has no support.
[0003] To address the above issues, we propose a woven bag with self-supporting capabilities. Utility Model Content
[0004] This invention proposes a woven bag with self-supporting capabilities, which solves the aforementioned problems existing in the use of existing technologies.
[0005] The technical solution of this utility model is implemented as follows: a woven bag with self-supporting capability includes a bag body, an inner cavity is opened in the bag body, support feet are fixed at the lower edge of the left and right sides of the bag body, and extension feet are symmetrically fixed on each support foot. Support rods are detachably connected between the extension feet on the same side, and two support rods are located on the front and rear sides of the bag body.
[0006] Several adhesive pads are glued to the front and rear side walls of the bag, and the two support rods can be detachably connected to each of the adhesive pads on the same side.
[0007] A further feature of this invention is that the adhesive pads on the front and back sides are vertically and equidistantly distributed on the bag body.
[0008] A further feature of this invention is that each of the aforementioned bases is symmetrically provided with a connecting base, a fixed shaft is fixedly connected between two of the aforementioned connecting bases, and a plug-in sleeve for inserting the support rod is fixedly provided on the fixed shaft.
[0009] The plug sleeve is tilted at a certain angle relative to the base.
[0010] A further feature of this invention is that the tilt angle of the lower plug sleeve is greater than the tilt angle of the upper plug sleeve.
[0011] A further feature of this invention is that: grooves are provided on the facing sides of the two extended legs on the same front and rear sides, and the left and right sides of the support rod are embedded in the two grooves, with the diameter of the support rod being the same as the inner diameter of the groove.
[0012] A further feature of this invention is that an upward-opening tightening groove is provided on the upper side of the curved sidewall of the groove, and the diameter of the tightening groove is smaller than the diameter of the groove.
[0013] A further feature of this invention is that rubber rings are fixedly provided on both the left and right sides of the support rod.
[0014] In summary, the beneficial effects of this utility model are as follows:
[0015] When the support rod and the extension foot are connected, they form a rectangle that is connected end to end, thereby limiting the shape of the bottom of the bag and supporting the bottom of the bag, so that technicians can arrange the self-supporting woven bag during transportation.
[0016] When technicians open the inner cavity and retrieve materials, they can remove the support rod from the extension foot, insert one side of the support rod into the insertion sleeve, and place the other side of the support rod against the ground to support the bag and prevent it from tipping over and leaking materials when technicians retrieve materials.

[0023] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Example:
[0025] like Figures 1 to 4 As shown, a self-supporting woven bag includes a bag body 11, with an internal cavity 12 for holding materials inside the bag body 11. Support legs 13 are fixed to the lower edges of both the left and right sides of the bag body 11. Each support leg 13 has symmetrically fixed extension legs 22. Support rods 14 are detachably connected between the extension legs 22 on the same front and rear sides. Two support rods 14 are located on the front and rear sides of the bag body 11. The connection between each support rod 14 and the extension legs 22 is as follows: grooves 19 are formed in the facing sides of the two extension legs 22 on the same front and rear sides, and the diameter of the support rod 14 is equal to the inner diameter of the groove 19. The upper edge of the curved sidewall of the groove 19 is provided with an upward-opening tightening groove 20. The inner diameter of the tightening groove 20 is smaller than the inner diameter of the groove 19. The technician makes the left and right sides of the support rod 14 pass through the tightening groove 20 from top to bottom and embed it in the groove 19, thereby achieving the purpose of fixing the support rod 14. After the support rod 14 is connected to the extension foot 22, the two and the support foot 13 form a rectangle connected end to end, thereby limiting the bottom shape of the bag body 11 and providing bottom support for the bag body 11, so that the technician can arrange the woven bag with self-supporting ability during transportation.
[0026] Furthermore, several adhesive seats 15 are adhered to the front and rear side walls of the bag body 11, and the adhesive seats 15 on the same side are vertically and equidistantly distributed on the bag body 11. Each adhesive seat 15 is symmetrically fixed with a connecting seat 16, and a fixed shaft 17 is fixedly connected between two connecting seats 16. An insertion sleeve 18 for inserting the support rod 14 is fixed on the fixed shaft 17. The insertion sleeve 18 is inclined at a certain angle relative to the adhesive seat 15. When the technician is taking out the material from the inner cavity 12, he can let one side of the bag body 11 lean against the wall, and then remove the support rod 14 from the groove 19 on the other side. One side of the support rod 14 is inserted into the insertion sleeve 18, and the other side of the support rod 14 abuts against the ground, so that the support rod 14 can support the bag body 11 and prevent the bag body 11 from tipping over and causing material leakage when the technician takes out the material.
[0027] When there is a lot of material in the inner cavity 12, the technician can insert the support rod 14 into the upper insertion sleeve 18;
[0028] When the material in the inner cavity 12 is small, the technician can insert the support rod 14 into the lower insertion sleeve 18 to ensure that the support rod 14 can support the bag body 11 regardless of the amount of material in the inner cavity 12, thereby preventing the bag body 11 from tipping over when the technician is scooping up the material.
[0029] Furthermore, the tilt angle of the lower insertion sleeve 18 (the angle between the insertion sleeve 18 and the bag body 11) is greater than the tilt angle of the upper insertion sleeve 18, so that no matter which insertion sleeve 18 the support rod 14 is inserted into, the end that is not connected to the insertion sleeve 18 can abut against the ground, thereby supporting the bag body 11 and preventing the bag body 11 from tipping over. Of course, technicians can also remove the two support rods 14 so that both of them can simultaneously support the front and rear sides of the bag body 11.
[0030] In addition, rubber rings 21 are fixed at both the left and right edges of the support rod 14 to increase the friction between the support rod 14 and the ground, thereby preventing the side of the support rod 14 in contact with the ground from slipping, and further ensuring that the support rod 14 can stably support the bag body 11.
[0031] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
