Description

Technical Field

[0001] This utility model relates to the field of logistics equipment technology, and in particular to a foldable steel mesh logistics box with stacking and fixing functions. Background Technology

[0002] In today's highly developed commodity circulation and supply chain system, logistics boxes are an indispensable logistics tool, widely used in the storage, transportation and distribution of various goods. Logistics boxes are mainly used for classifying and storing various items and transporting them in a centralized manner, which can effectively improve the efficiency of logistics operations, reduce the risk of damage to goods during transportation, and ensure the integrity of goods.

[0003] Traditional logistics boxes mainly consist of a frame and a lid. Due to the lack of an effective stacking and securing design, they are difficult to stack stably during cargo transportation and storage, and are prone to tipping over. This not only reduces space utilization but may also damage goods. Existing technologies use corresponding brackets and buckles at the bottom and top of the logistics boxes to make them stackable and prevent collapse. However, when loading and unloading items, workers have to bend over to place the items inside the logistics boxes, which can lead to lumbar muscle strain and is detrimental to health due to prolonged work. Since existing stackable logistics boxes do not have a door structure, they cannot be opened or closed from the side, reducing the practicality of the device. Utility Model Content

[0031] 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.

[0032] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a foldable steel mesh logistics box with stacking and fixing functions, including a base plate 1. The base plate 1 serves as the basic load-bearing component of the entire logistics box, providing an installation and support platform for other components. Limiting seats 3 are fixedly connected to the four corners of the top of the base plate 1, serving to limit and connect the first column 4 and the second column 5. The two adjacent sides of the left-side limiting seats 3 are rotatably connected to the first column 4, which serves as the support structure on the left side of the logistics box, forming the frame of the logistics box together with other components. The two adjacent sides of the right-side limiting seats 3 are rotatably connected to the second column 5, serving as the support structure on the right side of the logistics box, working in conjunction with the first column 4 to maintain the stability of the overall frame of the logistics box. The outer sides of the two left-side first columns 4... A single mesh panel 6 is fixedly connected to the left side of the wall, forming the left-side enclosure of the logistics box. This prevents goods from falling from the left side and provides ventilation and visibility for easy observation. A single mesh panel 27 is fixedly connected to the right side of the outer walls of the two right-side pillars 25, forming the right-side enclosure of the logistics box. Corresponding to mesh panel 6, it also prevents goods from falling from the right side and provides ventilation and visibility. The outer walls of the two left-side pillars 14 and the two right-side pillars 14 are provided with sliding grooves 7. Sliding sliders 8 are slidably connected to the inner walls of multiple sliding grooves 7. The outer walls of multiple limiting seats 3 are provided with limiting grooves 9. Multiple sliding sliders 8 are slidably connected to their corresponding limiting grooves 9. The sliding sliders 8 slide within the sliding grooves 7 and simultaneously interact with the limiting grooves 9 on the limiting seats 3. The interaction ensures the stability of the columns during rotation and prevents them from swaying randomly. A rear mesh plate 10 is rotatably connected to the top rear side of the base plate 1, forming the rear enclosure of the logistics box. The outer wall of the rear mesh plate 10 is equipped with a clip and mechanism 2 for quick connection between the rear mesh plate 10 and the rear columns 4 and 5. A front mesh plate 11 is rotatably connected to the top front side of the base plate 1, and a second mesh plate 12 is rotatably connected to the top of the front mesh plate 11. The second mesh plate 12 further improves the front enclosure structure of the logistics box. Both the front mesh plate 11 and the second mesh plate 12 have fixing components on their outer walls. These fixing components include multiple fixing plates 13, which are respectively fixedly connected to the left and right sides of the front end of the outer walls of the front mesh plate 11 and the second mesh plate 12. The inner walls of the multiple fixing plates 13... Each of the multiple fixed plates 13 is slidably connected with a sliding rod 14. The sliding rod 14 slides within the fixed plate 13 and, by engaging with the slot 17 on the rear column, enables the detachable connection between the front mesh plate 11 and the second mesh plate 12 and the rear column. The opposite ends of the multiple fixed plates 13 are each fixedly connected with a spring 15 to provide elasticity for the sliding rod 14. The other ends of the multiple springs 15 are each fixedly connected with a limiting plate 16 to limit the extension of the springs 15. The multiple sliding rods 14 are respectively fixedly connected to the corresponding limiting plates 16. The adjacent sides of the rear column 14 and column 25 each have two slots 17. The slots 17 engage with the sliding rods 14 to provide a fixed position for the front mesh plate 11 and the second mesh plate 12. The opposite ends of the multiple sliding rods 14 are respectively engaged with the corresponding slots 17.

[0033] Specifically, when folding a folding steel mesh logistics box with stacking and fixing functions, first operate the fixing components. Grasp the sliding rod 14 by hand and apply force towards the fixing plate 13, causing the spring 15 to be compressed and contracted. At this time, the sliding rod 14, which is connected to the limiting plate 16, will disengage from the corresponding slots 17 on the rear uprights 4 and 5. This releases the fixing relationship between the front mesh plate 11 and the mesh plate 12 and the rear uprights. Since the front mesh plate 11 is rotatably connected to the top front of the bottom plate 1, and the mesh plate 12 is rotatably connected to the top of the front mesh plate 11, the front mesh plate 11 can be flipped backward, and the mesh plate 12 will also flip, making it close to the front of the bottom plate 1. Similarly, the rear mesh plate 10, which is rotatably connected to the top rear of the bottom plate 1, will flip forward and fit against the rear of the bottom plate 1 after there are no other connection restrictions. Finally, handle the uprights by pushing the multiple sliders 8 upward, causing the multiple sliders 8 to disengage from the corresponding limiting grooves 9, thus releasing the sliders 8 from the limiting grooves 9 and the sliding grooves 7. The limiting mechanism between the two sections allows the columns 1-4 and 2-5 to rotate downwards, thereby enabling the folding of the mesh panels 1-6 and 3-7, reducing space occupation. When using the logistics box, first rotate the folded columns 1-4 and 2-5 from their position close to the wall panel 1 until each slide groove 7 aligns with its corresponding limiting groove 9. Then, slide the slider 8 downwards, locking it between the slide groove 7 and the limiting groove 9, thus restricting the rotation of columns 1-4 and 2-5. Finally, unfold the rear mesh panel 10, aligning it with the rear side. Align the first upright 4 and the second upright 5, then unfold the front mesh panel 11 and the second mesh panel 12, and release the sliding rod 14. At this time, the second spring 15 restores its elastic deformation, pushing the sliding rod 14 into the slot 17 of the rear upright 4 and the second upright 5, thereby firmly connecting the front mesh panel 11, the second mesh panel 12 and the rear upright. At this point, the first mesh panel 6, the second mesh panel 12, the rear mesh panel 10, the third mesh panel 27 and the bottom plate 1 together form a complete logistics box, which can be used to store and transport goods.

[0034] Reference Figure 1 and Figure 5The card and mechanism 2 includes two fixing blocks 201. The front sides of the outer walls of the two fixing blocks 201 are respectively fixedly connected to the left and right sides of the rear end of the outer wall of the rear mesh plate 10. The fixing blocks 201 serve as connections and supports, providing an installation base for subsequent components. Hollow sleeves 202 are fixedly connected to adjacent sides of the two fixing blocks 201, providing sliding space for the insertion rods 203. Insertion rods 203 are slidably connected to the inner walls of the two hollow sleeves 202. By sliding within the hollow sleeves 202, they cooperate with the slots 206 on the rear column 1 4 and column 2 5 to achieve the connection and fixation between the rear mesh plate 10 and the rear column. Limit plates are fixedly connected to the outer walls of the two insertion rods 203. 1. Limiting the sliding range of the insertion rod 203, each of the two limiting plates 204 is fixedly connected to a spring 205 on an adjacent side. The other end of each spring 205 is fixedly connected to the inner wall of the corresponding hollow sleeve 202, providing the insertion rod 203 with an automatic reset elastic force, so that it can automatically maintain the state of being engaged with the slot 206 when not subjected to external force. Each of the rear pillars 4 and 5 has a slot 206 on an adjacent side, which is adapted to the insertion rod 203 and provides an engagement position for the insertion rod 203, so as to achieve a tight connection between the rear mesh plate 10 and the rear pillar. The opposite ends of the two insertion rods 203 are engaged with the corresponding slots 206 respectively.

[0035] Specifically, when assembling a logistics box, the rear mesh panel 10 is placed in the appropriate position, aligning the insertion rod 203 with the slots 206 on the first and second uprights 4 and 5. Since the first spring 205 is in its naturally extended state, it pushes the first limiting plate 204 and the connected insertion rod 203 towards the slots 206. When the insertion rod 203 contacts the slot 206, under the elastic force of the first spring 205, the insertion rod 203 smoothly inserts into the slot 206, achieving the engagement connection between the rear mesh panel 10 and the rear upright, thus firmly fixing the rear mesh panel 10 to the logistics box. The rear side of the logistics box becomes part of the overall structure of the logistics box, ensuring the stability of the logistics box during use. When the logistics box needs to be folded, the connection between the rear mesh plate 10 and the rear upright should be released. At this time, pull the insert rod 203 towards the hollow sleeve 202. The limiting plate 204 moves the insert rod 203 together and compresses the spring 205. As the insert rod 203 is gradually pulled out from the slot 206, the connection between the rear mesh plate 10 and the rear upright is released, and the rear mesh plate 10 can be flipped forward and folded, making it convenient for the logistics box to be folded and stored as a whole, reducing space occupation.

[0036] Reference Figure 1 , Figure 4 and Figure 6An information board 18 is provided on the left side of the outer wall of the mesh panel 6. The information board 18 is used to display relevant information about the logistics box. Two screws 19 are threadedly connected to the outer wall of the information board 18. The rear ends of the two screws 19 are threaded to the mesh panel 6, so that the screws 19 can be screwed into the mesh panel 6, thereby fixing the information board 18 to the left side of the outer wall of the mesh panel 6. The left end of the two screws 19 is provided with a cross groove 20. The outer wall of the two screws 19 is smoothed. The smooth outer wall of the screws 19 can reduce friction wear and facilitate the installation and removal of the information board 18.

[0037] Specifically, the information board 18 is used to display relevant information about the logistics box. By inserting a screwdriver into the cross groove 20 on the left end of the screw 19 and rotating the screwdriver, the screw 19 can be screwed into the mesh plate 6 using the thread connection principle, thereby fixing the information board 18 to the left side of the outer wall of the mesh plate 6. The outer wall of the screw 19 is smooth to reduce friction and wear, making it easy to install and remove the information board 18.

[0038] Reference Figure 1 , Figure 2 and Figure 4 Support legs 21 are fixedly connected to the four corners of the bottom of the base plate 1. Support grooves 22 are opened at the top of the two columns 4 and the two columns 5. The multiple support legs 21 are engaged with the corresponding support grooves 22. When the logistics box is placed, the support legs 21 at the bottom corners of the base plate 1 are inserted into the support grooves 22 at the top of the columns to achieve stacking and positioning, so that the upper logistics box is stably placed on the lower layer. The bottom of the base plate 1 is rotatably connected to the four sides of the bottom. The outer wall of the multiple movable wheels 23 is provided with brake plates 24. The movable wheels 23 facilitate the movement of the logistics box. When it is necessary to fix it, the brake plates 24 can be stepped on. The top of the multiple limit seats 3 is fixedly connected to the magnet 25. The outer wall of the multiple sliders 8 is fixedly connected to the magnet 26. The magnet 25 on the limit seat 3 and the magnet 26 on the slider 8 attract each other to assist in the positioning of the column, ensuring that it is in the right position, improving the convenience of operation and structural stability.

[0039] Specifically, when the logistics box is placed, the support leg 21 at the bottom corner of the base plate 1 is inserted into the support groove 22 at the top of the column to achieve stacking and positioning, so that the upper logistics box is stably placed on the lower layer. The moving wheel 23 facilitates the movement of the logistics box. When it needs to be fixed, the brake plate 24 can be stepped on. During the folding and unfolding of the column, the magnet 25 on the limit seat 3 and the magnet 26 on the slider 8 attract each other to assist in the positioning of the column, ensuring that it is in the right position, improving the convenience of operation and structural stability.

[0040] Working principle: During disassembly, manually grasp the sliding rod 14 and apply force towards the fixing plate 13 to compress the second spring 15. This action causes the sliding rod 14, connected to the second limiting plate 16, to disengage from the slots 17 of the rear uprights 4 and 5, thereby releasing the fixing relationship between the front mesh plate 11 and the second mesh plate 12 and the rear uprights. Since the front mesh plate 11 is rotatably connected to the top front side of the bottom plate 1, and the second mesh plate 12 is rotatably connected to the top of the front mesh plate 11, the front mesh plate 11 can be easily flipped backward. The second mesh plate 12 also rotates accordingly, bringing it close to the front side of the bottom plate 1, pushing multiple sliders 8 upward to disengage them from the limiting groove 9, thus releasing the limiting constraints between the sliders 8 and the limiting groove 9 and the sliding groove 7. In this way, the first upright 4 and the second upright 5 can rotate downward, realizing the folding of the first mesh plate 6 and the third mesh plate 27, thereby effectively reducing the space occupied by the logistics box and facilitating storage. During transportation and installation, first rotate the folded uprights 4 and 5 from their positions close to the base plate 1. When each slide groove 7 coincides with the corresponding limiting groove 9, slide the slider 8 downwards to lock it between the slide groove 7 and the limiting groove 9, thereby restricting the rotation of uprights 4 and 5 and ensuring that the uprights are stable and upright. Then unfold the rear mesh plate 10 and align it with the rear uprights 4 and 5. Next, unfold the front mesh plate 11 and mesh plate 12, and release the sliding rod 14. At this time, the spring 2 15 returns to its elastic deformation and pushes the sliding rod 14 into the slot 17 of the rear uprights 4 and 5, so that the front mesh plate 11, mesh plate 2 12 and the rear uprights are firmly connected. Thus, mesh plate 6, mesh plate 2 12, rear mesh plate 10, mesh plate 3 27 and base plate 1 together constitute a complete logistics box, which can be used for the storage and transportation of goods.

[0041] Furthermore, when it is necessary to open the rear mesh panel 10 to remove the object, grasp the sliding rod 14 and apply force towards the fixed plate 13 to compress the second spring 15, causing the sliding rod 14 to disengage from the slot 17 of the rear upright 4 and the second upright 5. This releases the fixed relationship between the front mesh panel 11 and the second mesh panel 12 and the rear upright. Since the front mesh panel 11 is rotatably connected to the top front side of the base plate 1 and the second mesh panel 12 is rotatably connected to the top of the front mesh panel 11, the front mesh panel 11 can be flipped backward, and the second mesh panel 12 will then be close to the front side of the base plate 1. At the same time, the rear mesh panel 10, which is rotatably connected to the top rear side of the base plate 1, will flip forward and fit against the rear side of the base plate 1 after the connection restriction is removed. Finally, push the multiple sliders 8 upward to disengage from the limiting groove 9. Release the limiting groove 9 and slide 7 to allow the first column 4 and the second column 5 to rotate downwards, thereby folding the first mesh panel 6 and the third mesh panel 27 to reduce space occupation. When using the logistics box, first rotate the folded first column 4 and the second column 25 from the position close to the bottom plate 1. After the slide 7 and the limiting groove 9 are aligned, slide the slider 8 downwards and lock it between the two to restrict the rotation of the columns. Then unfold the rear mesh panel 10 and align it with the rear column. Next, unfold the front mesh panel 11 and the second mesh panel 12. Release the slide rod 14 and let the spring 2 15 restore its elastic deformation to push the slide rod 14 into the rear column slot 17, so that all parts are firmly connected to form a complete logistics box for storing and transporting goods.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
