Technical Field

[0001] This utility model relates to packaging bags, and more particularly to a packaging bag that is easy to use. Background Technology

[0002] Packaging bags are bags used to package various products, making it convenient to transport and store goods during the production and distribution process.

[0003] Existing packaging bags consist of a bag body with a receiving cavity inside. An opening is located on the bag body above the receiving cavity. Items are placed into the receiving cavity through the opening for packaging. These bags are used to seal various goods, aiming to simplify the transportation and storage of goods during production and distribution. Traditionally designed packaging bags contain a main structure that forms a storage space inside, with an opening for easy insertion and removal of items. However, when the depth of the storage space (receiving cavity) significantly exceeds the height of the packed items, users need to reach into the bag to retrieve them, increasing inconvenience. Therefore, designing a packaging bag with an adjustable internal storage space to accommodate items of different heights and ensure easy access has become a problem urgently needing to be solved by those skilled in the art. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a convenient packaging bag that can accommodate items of different heights by fastening the adjustment section with the matching plates at different positions to achieve different degrees of upward folding of the bottom of the bag body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a bag body and a receiving cavity located within the bag body. The length of the bag body extends vertically. The bag body is made of a flexible material, and a rolling rod extending horizontally is fixedly installed at the bottom. The bag body includes left and right cardboard panels on both sides. Several mating plates are spaced apart along the vertical direction on the left cardboard panel, and each mating plate is rotatably mounted on the left cardboard panel. The bag body includes an adjustment section at the bottom. The rolling rod is fixedly installed on the adjustment section, and a mating slot is provided on the adjustment section corresponding to each mating plate. One of the mating plates is inserted into the mating slot and detachably connected to the adjustment section.

[0006] The present invention is further configured such that: the left cardboard is provided with a rotating groove on the rotation trajectory of each mating plate corresponding to each mating plate; each mating plate includes a fixed section and a limiting section; the length direction of each fixed section extends forward and backward and is rotatably installed on the corresponding left cardboard; the adjusting section is located in front of the corresponding fixed section and is made of a material that is easily deformed.

[0007] The present invention is further configured such that each of the limiting segments is inclined from front to back and from top to bottom.

[0008] The present invention is further configured such that the left cardboard and the right cardboard are the same in shape and size and are both detachably connected to the bag body.

[0009] The present invention is further configured such that: each of the mating plates is provided with a disassembly section and a connecting section, each connecting section extends along the front and back in the length direction and one end is connected to the corresponding mating plate and the other end is connected to the corresponding disassembly section, and each disassembly section is parallel to the length direction of the mating plate and is detachably connected to the bag body.

[0010] The present invention is further configured such that: the left cardboard includes an installation section on which several mating plates are rotatably mounted and a mating section located above the installation section; the length direction of the installation section extends vertically and the length direction of the mating section is perpendicular to the length direction of the installation section; the mating section is provided with an installation groove for inserting the bag body; and both the installation section and the mating section are detachably connected to the bag body.

[0011] The present invention is further configured such that: a rear magnet is fixedly installed on each of the mounting sections, and a front magnet is provided on each of the rear magnets on the bag body.

[0012] The present invention is further configured such that: the corresponding mating section of the bag body is provided with a disassembly and assembly component made of a material that is prone to deformation; the disassembly and assembly component includes a fixing post and a limiting cone located on the rear side of the fixing post; the diameter of the limiting cone is larger than the diameter of the fixing post; the fixing post is inserted into the mating section and the front end face of the limiting cone abuts against the rear end face of the mating section.

[0013] By adopting the above technical solution, through the design of the bottom flip-up rod and adjustment section, users can adjust the effective height of the containing cavity according to the height of the items, making the packaging bag more adaptable to items of different sizes and facilitating the removal of items. Specifically, by selecting the height at which the adjustment section is folded upwards, the mating slot on the adjustment section can engage with the mating plate of the corresponding height. At this time, rotating the mating plate upwards allows one end of the mating plate to be detachably connected to the mating section, thus determining the position of the adjustment section after it is folded upwards. At this time, the height of the containing cavity is adjusted, and after placing the items of the corresponding height into the bag, it becomes easier to reach the bottom of the bag and remove the items from the bag.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-6As shown, a user-friendly packaging bag includes a bag body 1 and a receiving cavity 11 located within the bag body 1. The bag body 1 extends vertically along its length. The bag body 1 is made of a flexible material and has a horizontally extending roll-up rod 131 fixedly installed at its bottom. The bag body 1 includes a left cardboard 2 and a right cardboard 3 on its left and right sides. The left cardboard 2 has several mating plates 21 spaced vertically, and each mating plate 21 is rotatably mounted on the left cardboard 2. The bag body 1 includes an adjustment section 13 at the bottom. The roll-up rod 131 is fixedly installed on the adjustment section 13, and the adjustment section 13 has mating slots 132 corresponding to the mating plates 21. One of the mating plates 21 is inserted into the mating slot 132 and is detachably connected to the adjustment section 13. The roll-up rod 131 at the bottom and the adjustment section 13 are connected by a rolling mechanism. The design allows users to adjust the effective height of the receiving cavity 11 according to the height of the items being packed, making the packaging bag more adaptable to items of different sizes and facilitating the removal of items. Specifically, by selecting the height at which the adjustment section 13 is folded upwards, the mating slot 132 on the adjustment section 13 can engage with the mating plate 21 of the corresponding height. At this time, the mating plate 21 is rotated upwards, and one end of the mating plate 21 can be detachably connected to the mating section 23, thus determining the position of the adjustment section 13 after it is folded upwards. At this time, the height of the receiving cavity 11 is adjusted, and after placing the items of the corresponding height into the bag body 1, it is easier to reach the bottom of the bag body 1 and remove the items from the bag body 1.

[0027] The left cardboard 2 is provided with a rotating groove 22 on the rotation trajectory of each mating plate 21. Each mating plate 21 includes a fixed section 211 and a limiting section 212. The length of each fixed section 211 extends forward and backward and is rotatably mounted on the corresponding left cardboard 2. The adjusting section 13 is located in front of the corresponding fixed section 211 and is made of a material that is easily deformable. 1. Because the left cardboard 2 is provided with a rotating groove 22 on the rotation trajectory of each mating plate 21, when the adjusting section 13 is fastened with different mating plates 21, other mating plates 21 located below the selected mating plate 21 can be located in the corresponding rotating groove 22 without affecting the bottom of the bag body 1 being lifted and folded upward; 2. Because each mating plate 21 is made of a material that is easily deformable and Each limiting segment 212 is located in front of the corresponding fixed segment 211. Therefore, when the adjusting segment 13 is engaged with the mating plate 21 of the selected height, the limiting segment 212 of the mating plate needs to forcibly pass over the corresponding mating slot 132 to achieve the fixed segment 211 being located in the corresponding mating slot 132. The rear end face of the limiting segment 212 abuts against the adjusting segment 13 to achieve the engagement of the adjusting segment 13 with the mating plate 21. At this time, the lower part of the adjusting segment 13 of the bag body 1 is fixed on the mating plate 21, that is, the bottom of the bag body 1 is folded upward. Similarly, if it is necessary to adjust the depth of the receiving cavity 11 to achieve engagement with an item of another height, firstly, the adjusting segment 13 is forcibly separated by applying a forward force, and then the height of the item determines whether to engage the adjusting segment 13 with another mating plate 21.

[0028] Each of the limiting segments 212 is inclined from front to back and from top to bottom. Since each limiting segment 212 is inclined, when the limiting segment 212 is inserted into the mating slot 132 and needs to be forcibly pushed past the mating slot 132, the limiting segment 212 can be squeezed toward the fixed segment 211 and thus pass past the mating slot 132. After passing past the mating slot 132, the limiting segment 212 returns to its inclined shape and can then abut against the adjusting segment 13 to complete the height adjustment of the receiving cavity 11. Similarly, when it is necessary to separate the limiting segment 212 from the mating segment 23, the limiting segment 212 can be bent forward so that it can pass backward through the mating slot 132, thus separating the mating segment 23 from the limiting segment 212.

[0029] Preferably, the left cardboard 2 and the right cardboard 3 are the same in shape and size and are detachably connected to the bag body 1. The detachable connection between the left cardboard 2 and the right cardboard 3 and the bag body 1 means that users can easily assemble or disassemble the packaging bag when they need to replace the left cardboard 2 and the right cardboard 3, thereby improving the convenience and flexibility of use. Furthermore, since the left cardboard 2 and the right cardboard 3 are the same in shape and size, only one specification needs to be produced when manufacturing the left cardboard 2 and the right cardboard 3. At the same time, when replacing the left cardboard 2 and the right cardboard 3, only the left cardboard 2 or the right cardboard 3 needs to be available to complete the replacement.

[0030] Furthermore, the left cardboard 2 includes an installation section 24 on which several mating plates 21 are rotatably mounted, and a mating section 23 located above the installation section 24. The length direction of the installation section 24 extends vertically, and the length direction of the mating section 23 is perpendicular to the length direction of the installation section 24. The mating section 23 is provided with an installation groove for inserting the bag body 1. Both the installation section 24 and the mating section 23 are detachably connected to the bag body 1. Since both the installation section 24 and the mating section 23 are detachably connected to the bag body 1, after the left cardboard 2 is fixed to the bag body 1, the left cardboard 2 can be stably connected to the bag body 1. If the installation section 24 or the mating section 23 of the left cardboard 2 separates from the bag body 1, the other part is still connected to the bag body 1, which reduces the possibility of the left cardboard 2 being lost when it separates from the bag body 1. After the mating plates 21 are placed on top of the bag body 1, it can facilitate the connection and fixation of the mating section 23 to the bag body 1.

[0031] Preferably, each of the mounting sections 24 is fixedly equipped with a rear magnet 241, and the bag body 1 is provided with a front magnet 12 corresponding to each rear magnet 241. The design of the rear magnet 241 and the front magnet 12 helps to enhance the connection strength between the bag body 1 and the mating section 23, ensuring the integrity of the packaging bag during transportation and storage.

[0032] The bag body 1 has a protruding assembly 4 made of a deformable material such as rubber for the mating section 23. The assembly 4 includes a fixing post 41 and a limiting cone 42 located behind the fixing post 41. The diameter of the limiting cone 42 is larger than the diameter of the fixing post 41. The fixing post 41 is inserted into the mating section 23, and the front end face of the limiting cone 42 abuts against the rear end face of the mating section 23. Therefore, when the mating section 23 is installed on the bag body 1, the limiting cone 42 is the first part of the assembly 4 on the bag body 1 to be inserted into the mating section 23. Because the rear diameter of the limiting cone 42 is larger than the diameter of the fixing post 41, after the limiting cone 42 forcibly passes the position where the fixing post is inserted in the mating section 23, the limiting cone 42 will abut against the bag body 1. Therefore, without the action of external force, the mating section 23 can be stably connected with the bag body 1. When it is necessary to separate the mating section 23 from the bag body 1, a forward force needs to be applied to the limiting cone 42 to forcibly pass the position where the fixing post is inserted in the mating section 23, and then the mating section 23 is separated from the bag body 1.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
