Description

Technical Field

[0001] This application relates to the field of fruit and vegetable storage and transportation technology, and in particular to a foldable fruit and vegetable box. Background Technology

[0002] Fruit and vegetable boxes are indispensable tools in the production, distribution, and turnover of fruits and vegetables. They are mainly used to carry and transport fruits and vegetables, and must meet basic load-bearing stability. At the same time, they must provide a relatively breathable storage environment for fruits and vegetables, and be easy to handle manually or mechanically, so as to ensure the integrity and circulation efficiency of fruits and vegetables in the turnover process.

[0003] In related technologies, there are two main types of fruit and vegetable boxes used for transportation and turnover: one type is a one-piece injection molded fruit and vegetable box, which forms a complete box structure through a one-piece molding process; the other type is designed with a structure that is narrow at the bottom and wide at the top to improve storage convenience, so that multiple fruit and vegetable boxes can be stacked.

[0004] However, when not in use, injection-molded fruit and vegetable boxes cannot shrink due to their fixed structure, which takes up a lot of space and increases storage costs when idle. While stackable fruit and vegetable boxes that are narrow at the bottom and wide at the top can be stacked for storage, they sacrifice some of the internal space of the box to accommodate the stacking needs, resulting in a reduction in capacity. In addition, it is inconvenient to take the fruit and vegetable boxes from one box to another when they are stacked. At the same time, the bottom box still maintains its complete vertical space, which cannot fundamentally solve the space occupation problem. Utility Model Content

[0005] To address the aforementioned issues, this application provides a foldable fruit and vegetable box.

[0006] The foldable fruit and vegetable box provided in this application adopts the following technical solution:

[0007] A foldable fruit and vegetable box includes a bottom plate, a front panel, a side panel, and a small door panel. The bottom of the front panel and the side panel are both hinged to the bottom plate. The small door panel is located in the middle of the front panel and is hinged to the front panel. The hinge point between the side panel and the bottom plate is higher than the hinge point between the front panel and the bottom plate. A first hinge assembly is provided at both the hinge point between the side panel and the bottom plate and the hinge point between the front panel and the bottom plate. The first hinge assembly slides vertically on the bottom plate. A second hinge assembly is provided between the small door panel and the front panel. The small door panel and the front panel are connected by the second hinge assembly to form an openable connection. The rotation angle of the second hinge assembly is limited to a preset range.

[0008] By adopting the above technical solution, and through the setting of the first hinge assembly sliding vertically along the base plate, the front panel and side panels can achieve orderly staggered folding during folding. Firstly, when folding the front panel, the first front panel folds onto the base plate. The second front panel can then be moved vertically upward a certain distance using the first hinge assembly before folding onto the first front panel. Since the hinge point between the side panel and the base plate is higher than the hinge point between the front panel and the base plate, the first side panel folds onto the second front panel. The second side panel can then be moved vertically upward a certain distance using the first hinge assembly before folding onto the first side panel. This effectively reduces the impact of the front panel and side panels during folding. The interference between the panels allows the front and side panels to be tightly stacked, significantly reducing the storage volume. At the same time, the second hinge component limits the rotation angle of the small door panel, ensuring the stability of the small door panel during use without affecting the folding operation of the front panel. Overall, this improves the convenience of folding and storing the fruit and vegetable box and the space utilization rate. It solves the problems of injection-molded fruit and vegetable boxes that cannot be folded due to their fixed structure, occupy a large space when not in use, and increase storage costs. It also overcomes the shortcomings of stackable fruit and vegetable boxes that are narrow at the bottom and wide at the top, which sacrifice capacity to accommodate stacking, are inconvenient to take out when stacked, and still occupy vertical space at the bottom. This greatly improves the storage space utilization rate and folding convenience.

[0009] Preferably, the first hinge assembly includes a first hinge block, a first hinge shaft, and a mounting block. The first hinge block is fixedly connected to the first hinge block shaft. The base plate has a sliding groove. The mounting block is fixedly connected to the interior of the base plate. A portion of the mounting block is located above the sliding groove. The bottom of both the side panel and the front panel has mounting grooves. The first hinge block is inserted into the mounting groove. Both ends of the first hinge shaft are slidably disposed in the sliding groove. Both ends of the first hinge shaft are rotatably disposed in the sliding groove.

[0010] By adopting the above technical solution, the two ends of the first hinge shaft are slidably disposed within the sliding groove of the base plate, providing a basis for the vertical displacement of the side panels and the front panel along the base plate. The mounting block portion is located above the sliding groove, limiting the vertical displacement distance of the first hinge shaft within the sliding groove. This reduces the possibility of excessive displacement causing the side panels and front panel to loosen or detach from the base plate. This arrangement, combined with the insertion and engagement of the first hinge block with the mounting grooves at the bottom of the side panels and front panel, ensures that when the front panel is folded, the rotation of the first hinge shaft within the sliding groove, due to its rotatable placement within the sliding groove and the fixed connection between the first hinge block and the first hinge shaft, further drives the folding mechanism. The hinge block rotates, and because the hinge block is engaged with the mounting slot, it further drives the first front panel to rotate. After the first front panel rotates and folds to the bottom plate, the second front panel can move upward along the sliding slot within a limited distance with the help of the first hinge axis and then fold onto the first front panel. The side panels are folded in the same process, effectively realizing the staggered and compact stacking of the front and side panels. This not only solves the problem that the injection-molded fruit and vegetable boxes cannot shrink due to their fixed structure and occupy a lot of space when idle, but also overcomes the defects of the stacked fruit and vegetable boxes that are narrow at the bottom and wide at the top, which sacrifice capacity, are inconvenient to take out, and still occupy vertical space at the bottom. At the same time, the structural reliability of the folding process is improved by the limiting effect of the mounting block.

[0011] Preferably, the second hinge assembly includes a second hinge block, a second hinge shaft, and a third hinge shaft. The second hinge shaft is fixedly connected to the upper end of the second hinge block, the lower end of the second hinge block is rotatably supported by the third hinge shaft, the small door panel is rotatably supported by the second hinge shaft, and the third hinge shaft is fixedly connected to the entire panel.

[0012] By adopting the above technical solution, the small door panel can first rotate around the second hinge axis to detach from the front panel. Then, the second hinge block rotates around the third hinge axis, causing the small door panel to flip outward. This rotation method is suitable for the requirement of the small door panel opening outward. When fruits and vegetables are placed at the bottom, the small door panel can be unlocked and flipped through the above rotation process, effectively avoiding the obstruction of the operating space by the high front panel, providing enough space for people to place the fruits and vegetables at the bottom, and solving the problem of inconvenience in placing fruits and vegetables at the bottom when the front panel is high.

[0013] Preferably, the second hinge assembly further includes a stop block located on the side of the small door panel away from the second hinge block. The stop block is fixedly connected to the small door panel, and when the small door panel is in a vertical state, the stop block abuts against the inner wall of the front panel.

[0014] By adopting the above technical solution, when the small door panel is in a vertical state, the stop block abuts against the inner wall of the front panel, which can prevent the small door panel from rotating excessively into the box, ensuring the stability of the small door panel when closed and reducing the impact of shaking on the overall structural stability. When the small door panel is opened outward, the stop block will not obstruct the outward rotation of the small door panel, and it can be flipped normally through the rotational cooperation of the second hinge shaft, the second hinge block and the third hinge shaft, providing operating space for the bottom fruits and vegetables to be placed.

[0015] Preferably, a locking assembly is provided between the small door panel and the front panel. The locking assembly is located at both ends of the small door panel and includes an elastic element, a pull ring, and a blocking block. The elastic element is fixedly connected to one end of the pull ring, and the blocking block is fixedly connected to the other end of the pull ring. The front panel has a first limiting groove, the blocking block is built into the first limiting groove, the elastic element is built into the small door panel, and the pull ring is placed on the surface of the small door panel.

[0016] By adopting the above technical solution, when the operator pulls the pull ring located on the surface of the small door panel, the pull ring causes the elastic element to be squeezed and deformed elastically. At this time, the blocking block connected to the other end of the pull ring disengages from the first limiting groove of the front panel, thereby unlocking the small door panel from the front panel. This allows the small door panel to flip outward to provide space for placing fruits and vegetables at the bottom. After releasing the hand, the elastic element returns to its original position due to its own elasticity, causing the pull ring to return to its original position. The blocking block is then re-installed in the first limiting groove, completing the locking process. This ensures a stable connection between the small door panel and the front panel, reducing the chance of the small door panel opening accidentally during use, and does not affect the subsequent folding operation of the front panel, thus balancing loading convenience and structural stability.

[0017] Preferably, a first connecting component is further provided between the small door panel and the front panel. The first connecting component includes a limiting block and a second limiting groove. The limiting block is disposed on the edge of the front panel and is fixedly connected to the front panel. The second limiting groove is disposed on the edge of the small door panel.

[0018] By adopting the above technical solution, through the cooperation of the limiting block fixed on the front panel and the second limiting groove on the small door panel, the limiting block can be built into the second limiting groove during the closing process of the small door panel, providing precise positioning for the docking of the small door panel and the front panel, ensuring that the two are aligned when closed, reducing the occurrence of small door panel offset. At the same time, this cooperation can enhance the stability of the connection between the small door panel and the front panel, assist the locking component to better achieve locking, and will not cause interference during the opening and closing of the small door panel. It will not affect the operation of the small door panel flipping outward to provide placement space, nor will it hinder the subsequent folding action of the front panel, further improving the reliability of the connection between the small door panel and the front panel and the smoothness of the structural cooperation.

[0019] Preferably, a locking component is provided between the front panel and the side panel, the side panel is provided with a first limiting groove, the blocking block is built into the first limiting groove, the elastic element is built into the front panel, and the pull ring is placed on the surface of the front panel.

[0020] By adopting the above technical solution, when the operator pulls the pull ring located on the surface of the front panel, the elastic element is compressed and undergoes elastic deformation, causing the blocking block to disengage from the first limiting groove of the side panel, thus unlocking the device and facilitating the separation of the front panel and side panel for folding. After releasing the device, the elastic element returns to its original position, the pull ring returns to its original position, and the blocking block is repositioned in the first limiting groove, achieving locking. This ensures a stable connection between the front panel and side panel, guaranteeing the overall structural strength during use. At the same time, this structure is simple to operate, reduces relative swaying between the front panel and side panel in the locked state, and does not affect the folding action of the front panel and side panel after unlocking. It provides a basis for the orderly staggered folding of the front panel and side panel, further improving the stability of the box structure and the convenience of folding and storage.

[0021] Preferably, a second connecting component is provided between the front panel and the side panel. The second connecting component includes a positioning block and a positioning groove. The positioning block is disposed on the front panel, and the positioning groove is disposed on the side panel. The positioning block is built into the positioning groove.

[0022] By adopting the above technical solution, the positioning block on the front panel is built into the positioning groove on the side panel, which can provide precise positioning guidance when the front panel and side panel are assembled and docked, ensuring that the two are quickly aligned and reducing the occurrence of docking misalignment. At the same time, the cooperation between the positioning block and the positioning groove can enhance the initial stability of the connection between the front panel and the side panel, providing a basis for the locking action of the locking components between the two and improving the locking reliability. In addition, when the front panel and side panel are unlocked and folded, the positioning block can be smoothly disengaged from the positioning groove without interference, which not only ensures the stability of the connection between the two during use, but also does not affect the subsequent folding operation, further optimizing the convenience of cabinet assembly and the smoothness of structural cooperation.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When folding the front panel, the first front panel is folded to the bottom plate first. The second front panel moves vertically upward with the help of the first hinge component and then folds onto the first panel. The side panels are folded in the same way, which effectively avoids folding interference. Finally, they are compactly stacked, greatly reducing the storage volume. At the same time, the second hinge component ensures that the small door panel is stable when opening and closing and does not affect the folding of the front panel. This solves the problems of fixed structure, large space occupation and high storage cost when the injection molded one-piece fruit and vegetable box is not in use. It also overcomes the defects of the stacked fruit and vegetable box with a narrow bottom and wide top, which sacrifices the capacity for stacking, is inconvenient to take out, and still occupies vertical space at the bottom. Overall, it improves the convenience of folding and storage and the space utilization rate.

[0025] 2. The first hinge assembly slides within the sliding groove of the base plate through both ends of the first hinge shaft, providing a vertical displacement basis for the side panels and front panels along the base plate. The mounting block, fixed inside the base plate and partially located above the sliding groove, limits the vertical displacement distance of the first hinge shaft, reducing excessive displacement that could cause the side panels and front panels to loosen or detach from the base plate. Simultaneously, the insertion and engagement of the first hinge block with the mounting grooves at the bottom of the side panels and front panels ensures the stability of the connection between the panels and the hinge assembly. This structure allows the first front panel to fold to the base plate first when the front panel is folded. The second front panel can then move upwards along the sliding groove within a limited distance using the first hinge shaft before folding onto the first panel. The side panels fold in the same manner, effectively achieving a staggered and compact stacking. This solves the problems of fixed structure and large space occupation when not in use in injection-molded fruit and vegetable boxes, and overcomes the defects of narrow-bottom and wide-top stacked fruit and vegetable boxes that sacrifice capacity, are inconvenient to handle, and still occupy vertical space at the bottom. At the same time, the limiting effect of the mounting block improves the structural reliability of the folding process.

[0026] 3. The second hinge axis is fixed to the upper end of the second hinge block, and the small door panel rotates and is supported by the second hinge axis. The lower end of the second hinge block rotates and is supported by the third hinge axis fixed to the front panel, so that the small door panel can first rotate around the second hinge axis to detach from the front panel, and then rotate around the third hinge axis through the second hinge block to achieve outward flipping. This rotation method is adapted to the requirement of the small door panel opening outward. When placing bottom fruits and vegetables, the small door panel can be unlocked and flipped through the above rotation, effectively reducing the obstruction of the operating space by the high front panel, providing sufficient placement space for personnel, and solving the problem of inconvenience in placing bottom fruits and vegetables when the front panel is high.

[0041] The following is in conjunction with the appendix Figure 1-13 This application will be described in further detail.

[0042] This application discloses a foldable fruit and vegetable box. (See also...) Figure 1A foldable fruit and vegetable box includes a bottom plate 1, a front panel 2, a side panel 3, and a small door panel 4. The bottom of the front panel 2 and the side panel 3 are both connected to the bottom plate 1 by hinges. The small door panel 4 is located in the middle of the front panel 2 and is connected to the front panel 2 by hinges.

[0043] Furthermore, in this embodiment, there are two front panels 2, two side panels 3, and two small door panels 4. The two front panels 2 are arranged opposite each other, the two side panels 3 are arranged opposite each other, the edges of the front panels 2 and the side panels 3 are connected, the small door panels 4 correspond one-to-one with the front panels 2, and the small door panels 4 are hinged to the front panels 2.

[0044] Reference Figure 2 , Figure 3 as well as Figure 4 Meanwhile, the hinge point between the side panel 3 and the bottom plate 1 is higher than the hinge point between the front panel 2 and the bottom plate 1. Both the hinge point between the side panel 3 and the bottom plate 1 and the hinge point between the front panel 2 and the bottom plate 1 are provided with a first hinge component 5. The first hinge component 5 is slidably disposed on the bottom plate 1 in the vertical direction. A second hinge component 6 is provided between the small door panel 4 and the front panel 2. The small door panel 4 and the front panel 2 are connected to the front panel 2 through the second hinge component 6 to form an openable connection. The rotation angle of the second hinge component 6 is limited to a preset range.

[0045] This demonstrates that by sliding the first hinge assembly 5 vertically along the base plate 1, the front panel 2 and side panel 3 can be folded in an orderly staggered manner. When the front panel 2 is folded, the first front panel 2 is folded onto the base plate 1. The second front panel 2 can be moved upward a certain distance vertically with the help of the first hinge assembly 5, and then folded onto the first front panel 2. Since the hinge point between the side panel 3 and the base plate 1 is higher than the hinge point between the front panel 2 and the base plate 1, the first side panel 3 is folded onto the second front panel 2. The second side panel 3 can be moved upward a certain distance vertically with the help of the first hinge assembly 5, and then folded onto the first side panel 3. This effectively reduces the interference between the front panel 2 and the side panel 3 during the folding process, and finally the front panel 2 and the side panel 3 can be compactly stacked, greatly reducing the storage volume.

[0046] To further explain, the second hinge component 6 limits the rotation angle of the small door panel 4, which not only ensures the opening and closing stability of the small door panel 4 during use, but also does not affect the folding operation of the front panel 2. Overall, it improves the convenience of folding and storing the fruit and vegetable box and the space utilization rate. It solves the problems of the injection-molded fruit and vegetable box, which cannot be folded due to its fixed structure, occupies a large space when not in use, and increases storage costs. It also overcomes the defects of the stackable fruit and vegetable box, which is narrow at the bottom and wide at the top, which sacrifices the capacity to adapt to stacking, is inconvenient to take out when stacked, and still occupies vertical space at the bottom. It greatly improves the storage space utilization rate and folding convenience.

[0047] Specifically, the first hinge assembly 5 includes a first hinge block 51, a first hinge shaft 52, and a mounting block 53. In this embodiment, the first hinge assembly 5 is provided in twelve sets, with three sets provided for each front panel 2 and each side panel 3, located at the middle and both ends of the front panel 2, respectively.

[0048] Reference Figure 7 , Figure 8 as well as Figure 9 Furthermore, the first hinge block 51 is fixedly connected to the first hinge shaft 52. The first hinge shaft 52 is a component that connects the first hinge block 51 and enables the first hinge block 51 to rotate. The first hinge block 51 is cylindrical. The base plate 1 has a sliding groove 12. The first hinge shaft 52 is slidably disposed in the sliding groove 12 and can rotate within the sliding groove 12. The mounting block 53 is fixedly connected to the inside of the base plate 1, and part of the structure of the mounting block 53 is located above the sliding groove 12. The bottom of the side panel 3 and the front panel 2 are both provided with mounting grooves 7. The first hinge block 51 is inserted into the mounting groove 7, so that the side panel 3 and the front panel 2 can rotate around the first hinge shaft 52 through the first hinge block 51.

[0049] This explains that the first hinge shaft 52 is slidably disposed at both ends within the sliding groove 12 of the base plate 1, providing a basis for the side panel 3 and the front panel 2 to move vertically along the base plate 1. The mounting block 53 is partially located above the sliding groove 12, limiting the vertical displacement distance of the first hinge shaft 52 within the sliding groove 12, thus reducing the possibility of excessive displacement causing the side panel 3 and the front panel 2 to become loose or detached from the base plate 1.

[0050] Simultaneously, this arrangement, combined with the insertion and engagement of the first hinge block 51 with the side panel 3 and the bottom mounting groove 7 of the front panel 2, ensures that when the front panel 2 is folded, the first hinge shaft 52, with both ends rotatably mounted in the sliding groove 12 and the first hinge block 51 fixedly connected to the first hinge shaft 52, rotates within the sliding groove 12, further driving the first hinge block 51 to rotate. Since the first hinge block 51 is inserted and engaged with the mounting groove 7, this further drives the first front panel 2 to rotate. The first front panel 2 first rotates and folds to the bottom plate 1, and then the second... The front panel 2 can be moved upward within a limited distance along the sliding groove 12 by means of the first hinge shaft 52 and then folded onto the first front panel 2. The side panel 3 is folded in the same process, which effectively realizes the staggered and compact stacking of the front panel 2 and the side panel 3. This not only solves the problem that the injection-molded fruit and vegetable box cannot shrink due to its fixed structure and occupies a lot of space when idle, but also overcomes the defects of the stacked fruit and vegetable box with a narrow bottom and wide top, which sacrifices the capacity, is inconvenient to take out, and still occupies vertical space at the bottom. At the same time, the structural reliability of the folding process is improved by the limiting effect of the mounting block 53.

[0051] Furthermore, in this embodiment, the second hinge assembly 6 is provided in two sets. The second hinge assembly 6 includes a second hinge block 61, a second hinge shaft 62, and a third hinge shaft 63. The second hinge shaft 62 is fixedly connected to the upper end of the second hinge block 61, and the lower end of the second hinge block 61 is rotatably supported by the third hinge shaft 63. The small door panel 4 is rotatably supported by the second hinge shaft 62. The second hinge serves to connect and support. The second hinge shaft 62 and the third hinge shaft 63 are cylindrical and are used to realize the rotational connection between the components.

[0052] This means that the small door panel 4 can first rotate around the second hinge axis 62 to disengage from the front panel 2. Then, the second hinge block 61 rotates around the third hinge axis 63, causing the small door panel 4 to flip outward. This rotation method is suitable for the requirement of the small door panel 4 opening outward. When fruits and vegetables are placed at the bottom, the small door panel 4 can be unlocked and flipped through the above rotation process, effectively avoiding the obstruction of the operating space by the higher front panel 2, providing enough space for people to place the fruits and vegetables at the bottom, and solving the problem of inconvenience in placing fruits and vegetables at the bottom when the front panel 2 is high.

[0053] Reference Figure 5 In addition, the second hinge assembly 6 also includes a stop block 64, which is located on the side of the small door panel 4 away from the second hinge block 61. The stop block 64 is fixedly connected to the small door panel 4. When the small door panel 4 is in a vertical state, the stop block 64 abuts against the inner wall of the front panel 2, thus limiting the rotation angle of the small door panel 4 within a preset range. This can prevent the small door panel 4 from rotating excessively into the box, ensuring the stability of the small door panel 4 when closed and reducing the impact of shaking on the overall structural stability. When the small door panel 4 is opened outward, the stop block 64 will not obstruct the outward rotation of the small door panel 4. It can be flipped normally through the rotational cooperation of the second hinge shaft 62, the second hinge block 61 and the third hinge shaft 63, providing operating space for the bottom fruits and vegetables to be placed.

[0054] Reference Figure 10 and Figure 11 Furthermore, locking components 8 are provided between the small door panel 4 and the front panel 2, and between the front panel 2 and the side panel 3. In this embodiment, eight sets of locking components 8 are provided, with two sets for each of the two small door panels 4. The two sets of locking components 8 are fixed at both ends of the small door panel 4. Two sets of locking components 8 are provided for each of the two front panels 2. The two sets of locking components 8 are fixed at both ends of the front panel 2.

[0055] Meanwhile, a locking assembly 8 is provided between the front panel 2 and the side panel 3, and between the front panel 2 and the small door panel 4. Specifically, the locking assembly 8 includes an elastic element 81, a pull ring 82, and a blocking block 83. One end of the pull ring 82 is fixedly connected to the elastic element 81, and the other end of the pull ring 82 is fixedly connected to the blocking block 83. The elastic element 81 is made of elastic rubber and has elastic restoring force. The function of the elastic element 81 is to provide the force to reset the blocking block 83. The elastic element 81 has a ring structure and is provided with a fixing block 811. The small door panel 4 is provided with an internal cavity 9 for housing the elastic element 81. The side wall of the internal cavity 9 is provided with a fixing groove 91, and the fixing block 811 is inserted into the fixing groove 91.

[0056] Furthermore, the pull ring 82 is convenient for users to operate. The pull ring 82 is set as a ring structure and is placed on the surface of the small door panel 4. The blocking block 83 is used to realize the locking function. The blocking block 83 is a block structure. The front panel 2 has a first limiting groove 13. When the small door panel 4 and the front panel 2 are locked, the blocking block 83 is built into the first limiting groove 13.

[0057] This means that when the small door panel 4 needs to be opened, the pull ring 82 is pulled to disengage the blocking block 83 from the first limiting groove 13, and the small door panel 4 can be opened. When the small door panel 4 is closed, the elastic force of the elastic element 81 causes the blocking block 83 to re-insert into the first limiting groove 13, thereby locking it. The setting of the locking component 8 reduces the accidental opening of the small door panel 4 during use and does not affect the subsequent folding operation of the front panel 2, thus taking into account both the convenience of loading and the structural stability.

[0058] Meanwhile, the front panel 2 also has a built-in cavity 9 for housing the elastic element 81. The side wall of the built-in cavity 9 is provided with a fixing groove 91, and the fixing block 811 is inserted into the fixing groove 91. The side panel 3 is provided with a first limiting groove 13. When the side panel 3 and the front panel 2 are locked, the blocking block 83 is built into the first limiting groove 13, and the pull ring 82 is placed on the surface of the front panel 2. When the operator pulls the pull ring 82 placed on the surface of the front panel 2, the elastic element 81 is squeezed and elastically deformed, which drives the blocking block 83 to disengage from the first limiting groove 13 of the side panel 3, completing the unlocking. This facilitates the separation of the front panel 2 and the side panel 3 for folding. After releasing the hand, the elastic element 81 returns to its original position, the pull ring 82 returns to its original position, and the blocking block 83 is re-built into the first limiting groove 13, achieving locking and ensuring that the connection between the front panel 2 and the side panel 3 is stable, thus ensuring the overall structural strength during use.

[0059] Furthermore, this structure is easy to operate. When locked, it reduces the relative shaking between the front panel 2 and the side panel 3. When unlocked, it does not affect the folding action of the front panel 2 and the side panel 3, providing a basis for the orderly staggered folding of the front panel 2 and the side panel 3, further improving the stability of the box structure and the convenience of folding and storage.

[0060] Reference Figure 6 On the other hand, a first connecting component 10 is also provided between the edge of the small door panel 4 and the front panel 2. The first connecting component 10 includes a limiting block 101 and a second limiting groove 102. The limiting block 101 is set on the front panel 2 and fixedly connected to the front panel 2. The second limiting groove 102 is set on the small door panel 4. When the small door panel 4 is closed, the limiting block 101 is placed in the second limiting groove 102, providing precise positioning for the docking of the small door panel 4 and the front panel 2, ensuring that the positions of the two are aligned when closed, reducing the occurrence of the small door panel 4 offset. At the same time, this cooperation can enhance the stability of the connection between the small door panel 4 and the front panel 2, assist the locking component 8 to better achieve locking, and will not interfere during the opening and closing of the small door panel 4. It will not affect the operation of the small door panel 4 flipping outward to provide placement space, nor will it hinder the subsequent folding action of the front panel 2, further improving the reliability of the connection between the small door panel 4 and the front panel 2 and the smoothness of the structural cooperation.

[0061] Reference Figure 12 Meanwhile, a second connecting component 11 is provided between the front panel 2 and the side panel 3. The second connecting component 11 includes a positioning block 111 and a positioning groove 112. The positioning block 111 is provided on the front panel 2, and the positioning groove 112 is provided on the side panel 3. The positioning block 111 is built into the positioning groove 112. When the edge of the front panel 2 and the edge of the side panel 3 are connected, the positioning block 111 is built into the positioning groove 112.

[0062] This demonstrates that the positioning block 111 on the front panel 2 is built into the positioning groove 112 on the side panel 3, providing precise positioning guidance when the front panel 2 and the side panel 3 are assembled and docked, ensuring that the two are quickly aligned and reducing the occurrence of docking misalignment. At the same time, the cooperation between the positioning block 111 and the positioning groove 112 can enhance the initial stability of the connection between the front panel 2 and the side panel 3, providing a basis for the locking action of the locking component 8 between the two and improving the locking reliability. In addition, when the front panel 2 and the side panel 3 are unlocked and folded, the positioning block 111 can smoothly disengage from the positioning groove 112 without interference, which not only ensures the stability of the connection between the two during use, but also does not affect the subsequent folding operation, further optimizing the convenience of the box assembly and the smoothness of the structural cooperation.

[0063] The implementation principle of a foldable fruit and vegetable box in this application embodiment is as follows:

[0064] The operator pulls the pull ring on the surface of the small door panel. The deformation of the elastic element causes the blocking block to disengage from the first limiting groove of the front panel, releasing the locking state between the small door panel and the front panel. The small door panel rotates through the second hinge assembly. The small door panel first rotates outward around the second hinge axis, separating from the surface of the front panel. Then, the second hinge block rotates around the third hinge axis, causing the small door panel to flip outward further, avoiding the front panel's obstruction of the bottom. Vegetables and fruits are placed into the box through the opened small door panel. Vegetables and fruits at the bottom can be easily placed using the operating space after the small door panel is flipped. The blocking block limits the range of rotation of the small door panel into the box, ensuring the stability of the small door panel's position.

[0065] When the small door panel is closed, the limiting block on the edge of the small door panel aligns with the second limiting groove on the front panel. The elastic restoring force of the elastic element pushes the blocking block back into the first limiting groove on the front panel, completing the locking and reducing the risk of accidental opening.

[0066] On the other hand, the operator pulls the pull ring on the surface of the front panel, and the deformation of the elastic element causes the blocking block to disengage from the first limiting groove of the side panel, releasing the locking state between the front panel and the side panel. The first front panel is folded onto the bottom plate through the first hinge assembly, and the second front panel slides upward along the sliding groove of the bottom plate with the help of the first hinge shaft, and then folds onto the first front panel to achieve staggered stacking.

[0067] Since the hinge joint between the side panel and the bottom plate is higher than the front panel, the first side panel is folded onto the second front panel. The second side panel slides upward along the sliding groove through the first hinge axis and then folds onto the first side panel, which is synchronously and staggered with the front panel to reduce folding interference.

[0068] The small door panel folds naturally with the front panel, resulting in a compact overall structure that solves the problems of traditional fruit and vegetable boxes taking up space, low capacity of stackable fruit and vegetable boxes, and wasted bottom space.

[0069] When assembly is required, the stacked front panel and side panel are unfolded by rotating in the opposite direction through the first hinge assembly. The first hinge shaft is reset along the sliding groove. The edges of the front panel and side panel are connected to the positioning groove through the positioning block to achieve initial positioning. The elastic element pushes the blocking block to insert into the first limiting groove of the side panel to complete the locking of the front panel and side panel and ensure the stability of the structure.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
