Description

Technical Field

[0001] The present invention relates to the field of plastic suction boxes, and specifically to an impact-resistant and damage-proof plastic suction box. Background Art

[0002] Currently, existing plastic suction boxes are usually stacked during transportation. With bumps and shakes, the plastic suction boxes are not only subject to external collisions and squeezes, but also the items stored inside cannot be avoided from colliding with each other. Therefore, it is very easy to cause damage to the items stored inside, thus affecting the practicality of the plastic suction box. A collision-proof and pressure-resistant plastic suction box with a publication number of CN219258295U is retrieved, which includes a box body and a box cover that are detachably connected. It is characterized in that: the box cover extends vertically downward from the bottom peripheral edge to form a flange, and a clamping groove is formed by inward depression at the bottom of the flange. A clamping portion that extends vertically upward is provided on the box body corresponding to the flange. A storage groove for placing electronic products is evenly opened on one side of the box body where the clamping portion is located. A blocking plate for closing the storage groove is provided at the bottom of the box cover. A gap space is left between the top of the blocking plate and the bottom of the box cover. A number of pressure-resistant bodies are arranged at intervals in the gap space. The outer wall of the blocking plate is fixedly connected to the inner wall of the flange. A buffer pad is provided at the bottom of the blocking plate.

[0003] However, in the above technology, the pressure-resistant effect is achieved through the pressure-resistant body and the buffer pad, but it cannot effectively protect against squeezing and impacts from above, below, and from the side. Summary of the Invention

[0004] The problem to be solved by the present invention is to effectively withstand squeezing and impact forces from above, below, and from the side during the transportation or use of the plastic suction box.

[0005] To achieve the above object, the technical solution adopted by the present invention is an impact-resistant and damage-proof plastic suction box, which includes a box cover, a storage plate, and a base. Both the box cover and the base are rectangular boxes, and the box cover is movably connected to the base. It is characterized in that: corner support columns are provided on both the box cover and the base, and the corner support columns are respectively arranged at the corner positions around the box cover and the base. A central support platform is also provided at the center position of the box cover. The central support platform is in the shape of a frustum of a cone. A connecting strip is provided between the corner support columns and the central support platform. Reinforcing ribs are arranged inside the connecting strip. The reinforcing ribs are arranged in a wavy shape, and the undulating angle of each wave is 60°. The reinforcing ribs are point-connected to the wall surface of the connecting strip, and two reinforcing ribs are provided. The two reinforcing ribs are cross-arranged inside the connecting strip. A joint platform corresponding to the central support platform is also provided on the base. A connecting strip is also provided between the corner support columns of the base and the joint platform; the storage plate is fixed inside the base or fixed inside the base and the box cover.

[0006] As an embodiment, the height dimension of the central support platform is greater than the depth dimension of the box cover. A limiting block is provided at the end of the central support platform, and the limiting blocks are arranged in an annular array around the central support platform. Also, the joint platform is frustum-shaped, and the height dimension of the joint platform is greater than the depth dimension of the base. A circular slot is provided at the upper end of the joint platform, and the diameter of the circular slot is the same as the lower end diameter of the central support platform, so that the lower end of the central support platform can be inserted into the circular slot. And a limiting groove is provided on the inner side wall of the circular slot, and the limiting groove cooperates with the limiting block at the lower end of the central support platform, so that the limiting block can be snapped into the limiting groove.

[0007] As an embodiment, an anti-impact structure is further provided on the storage board. The anti-impact structure includes folding pieces and positioning inserts. The folding pieces are corrugated and are arranged around the storage board, so that the storage board is connected to the positioning inserts through the folding pieces. The positioning inserts are perpendicular to the storage board, and rectangular jacks matching the positioning inserts are provided on the inner side walls of the box cover and the base.

[0008] As an embodiment, the storage board is in the shape of a rectangular flat plate. A positioning hole is provided at the center position of the storage board, and the positioning hole can be sleeved on the central support platform and the joint platform. And egg grooves are evenly distributed on the storage board.

[0009] As an embodiment, protective frames are provided on both the box cover and the base, and the protective frames are connected to the corner support columns, so that there is a gap between the protective frames and the side walls of the box body.

[0010] As an embodiment, a connecting blind hole is further provided on the side wall of the box cover, and a corresponding connecting insert rod is provided on the side wall of the base. The connecting insert rod can be inserted into the connecting blind hole, and the connecting insert rod is rotatably matched with the connecting blind hole.

[0011] As an embodiment, magnetic attraction patches are further provided on the end faces of the corner support columns of the box cover and the base. The magnetic attraction patches on two oppositely arranged corner support columns can attract each other, improving the tightness when the box cover and the base are buckled.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the corner support columns on the box cover and the base, when the box cover and the base are buckled, the four corners of the box body can be supported. And through the connection between the central support platform and the joint platform, the central position of the box body can be supported. There is also a connection bar between the central support platform and the corner support columns. There are two reinforcing ribs in the connection bar, and both of the two reinforcing ribs are arranged in a 60° wave shape. Through the two 60° wave-shaped reinforcing ribs, a better strengthening and supporting effect can be provided. And through the anti-impact structure on the storage board, not only can the impact suffered by the side of the box body be reduced, but also when the upper and lower ends of the box body are subjected to pressure, the pressure on the products on the storage board can be reduced through the cooperation of the central support platform, the joint platform, and the corner support columns. It can better prevent the products in the box body from being damaged when the box body is impacted. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be an electrical connection; it can be a hydraulic oil circuit connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0026] Refer to Figures 1 to 9As shown, an impact-resistant and damage-proof plastic box can be used for packaging eggs, fruits, vegetables, etc. It includes a box cover 1, a storage board 3, and a base 2. Both the box cover 1 and the base 2 are rectangular boxes. An accommodation space is provided inside both the box cover 1 and the base 2, and the box cover 1 and the base 2 are movably connected. The box cover 1 can be buckled with the base 2 to form a complete box body. Corner support columns 4 are provided on the box cover 1, and the corner support columns 4 are respectively arranged at the corner positions around the box cover 1. The corner support columns 4 are perpendicular to the top cover of the box cover 1. A central support platform 5 is provided at the center position of the top wall of the box cover 1. The central support platform 5 is frustum-shaped, and the height dimension of the central support platform 5 is greater than the depth dimension of the box cover 1. A limiting block 6 is provided at the end of the central support platform 5. The limiting blocks 6 are arranged in a circular array around the central support platform 5. A connecting strip 7 is provided between the central support platform 5 and the corner support columns 4, and a reinforcing rib 8 is provided inside the connecting strip 7. The reinforcing rib 8 is arranged in a wavy shape, and the peak and valley positions of its wavy shape are connected to the wall surface of the connecting strip 7. The undulating angle of each wave is 60°. Through data testing of the box body and the reinforcing ribs at different angles, and computer simulation testing shows that when one end of the box body is fixed and a torque of 1 Nm is applied to the other end of the box body, when the included angle between the reinforcing ribs is 30°, the offset of the box body is 1.061 mm; when the included angle between the reinforcing ribs is 45°, the offset of the box body is 0.7111 mm; when the included angle between the reinforcing ribs is 60°, the offset of the box body is 0.5864 mm; when the included angle between the reinforcing ribs is 90°, the offset of the box body is 3.635 mm. According to the above simulation test results, when the included angle between the reinforcing ribs is 60°, the offset of the box body is the smallest. Therefore, when the undulating angle of the reinforcing rib is 60°, the supporting force provided is much higher than that of 30°, 45°, or 90°. The wave forms of the reinforcing rib 8 from the starting end to the ending end are consistent, and two reinforcing ribs 8 are provided. The two reinforcing ribs 8 are cross-arranged to increase the internal supporting force of the connecting strip 7, thereby avoiding deformation and depression of the box cover 1 after being impacted by an external force.

[0027] On the base 2, there are also corner support columns 4 and connecting bars 7. Different from the lid 1, a joint platform 9 is provided at the central position on the base 2. The joint platform 9 is also frustum-shaped, and the height dimension of the joint platform 9 is greater than the depth dimension of the base 2. A circular slot 10 is provided at the upper end of the joint platform 9. The diameter of the circular slot 10 is the same as the lower diameter of the central support platform 5, so that the lower end of the central support platform 5 can be inserted into the circular slot 10. And a limiting groove 11 is provided on the inner side wall of the circular slot 10. The limiting groove 11 cooperates with the limiting block 6 at the lower end of the central support platform 5, so that the limiting block 6 can be snapped into the limiting groove 11, thereby strengthening the connection between the lid 1 and the base 2. Drainage holes 18 are also provided on the lid 1 and the base 2. When washing fruits and vegetables on the lid 1 or the base 2, the water and sundries can be discharged through the drainage holes 18. And magnetic patch 17 is provided on the corner support columns 4 of the lid 1 and the base 2. Through the limiting groove 11, the limiting block 6 and the magnetic patch 17, the lid 1 and the base 2 are more tightly buckled after being closed.

[0028] A storage plate 3 is also provided on the base 2 and the lid 1. The storage plate 3 is in the shape of a rectangular flat plate. A positioning hole 12 is provided at the central position of the storage plate 3. The positioning hole 12 can be sleeved on the central support platform 5 or the joint platform 9. An anti-impact structure is also provided on the side walls around the storage plate 3. The anti-impact structure includes a folding piece 13 and a positioning insert 14. The folding piece 13 is corrugated and will be compressed when subjected to pressure and can return to its original state after the pressure disappears, thus playing a buffering role. The positioning insert 14 is perpendicular to the storage plate 3, and rectangular jacks 21 matching the positioning insert 14 are provided on the inner side walls of the lid 1 and the base 2, so that the positioning insert 14 can be inserted into the rectangular jacks 21 on the inner side walls of the lid 1 or the base 2, thereby installing the storage plate 3 in the lid 1 or the base 2. Egg grooves 19 are evenly distributed on the storage plate 3, so that the lower ends of the eggs can be placed in the egg grooves 19. And since accommodation spaces are provided in the lid 1 and the base 2, when the eggs are placed in the egg grooves 19 on the storage plate 3, the eggs do not contact the bottom wall of the base 2, and a certain distance is maintained between the bottom of the eggs and the bottom wall, so as to ensure that when impacted from the outside, the impact force will not directly act on the eggshells. And when storage plates 3 are installed in both the lid 1 and the base 2, eggs are placed in the egg grooves 19, and the lid 1 and the base 2 are buckled, so that the storage plate 3 in the lid 1 can cooperate with the eggs on the storage plate 3 in the base 2 for clamping and stabilizing. And if the eggs are too large, the storage plate 3 will be recessed, and at the same time, the folding pieces 13 on the side walls around the storage plate 3 will be stretched. Through the restoring force of the folding pieces 13, eggs of different sizes can be better stabilized, avoiding excessive extrusion force on the eggs by the two storage plates 3 being too hard and causing the eggs to break.

[0029] Among them, a protective frame 20 is provided on the lid 1 and the base 2. The protective frame 20 is arranged around the perimeter of the lid 1 and the base 2 and is connected to the corner support columns 4, creating a gap between the protective frame 20 and the side wall of the box body. When the outside is subjected to physical impact, the protective frame 20 can slow down a certain amount of impact force. At the same time, it can also convert part of the impact force into thrust. The converted thrust and the remaining impact force are slowed down by the protective frame 20 and then transmitted to the folding piece 13. The folding piece 13 further slows down the impact force, thus better protecting the eggs in the storage plate 3 from being damaged by external impacts. In addition, a connecting blind hole 15 is provided on the side wall of the lid 1, and a corresponding connecting plug 16 is provided on the side wall of the base 2. The connecting plug 16 can be inserted into the connecting blind hole 15 to connect the lid 1 and the base 2, and enable the lid 1 to be flipped and opened on the base 2. It is also possible to slightly bend the side wall where the connecting blind hole 15 is located, reducing the distance between the two connecting blind holes 15, thereby removing one of the connecting plugs 16, and then restoring the side wall to the vertical state and pulling out the other connecting plug 16 to separate the lid 1 and the base 2 for use.

[0030] In use, the two storage plates 3 are respectively installed on the box cover 1 and the base 2. Then, eggs are placed in the egg grooves 19 of the storage plate 3 in the base 2. Next, the box cover 1 is flipped and buckled on the base 2. At the same time, the central support platform 5 on the box cover 1 will be inserted into the circular slot 10 of the joint platform 9 on the base 2, so that the limiting block 6 of the central support platform 5 is snapped into the limiting groove 11 of the circular slot 10, and the egg groove 19 of the storage plate 3 in the box cover 1 is buckled on the upper end of the eggs. At this time, the magnetic attraction sheets on the corner support columns 4 attract and fit with each other, so that the box cover 1 and the base 2 can be better closed. When the closed box body is subjected to external pressure from the upper and lower ends, since the central support platform 5 is connected to the joint platform 9, and the corner support columns 4 in the box cover 1 and the corner support columns 4 in the base 2 also abut against each other, when subjected to pressure from the upper and lower ends, if the stress point is located at the center position or the four corners of the box body, the box body will not easily dent, avoiding damage to the stored items in the box; when the pressure comes from other positions, due to the setting of the connecting strip 7 and the wavy reinforcing ribs 8 are arranged in the connecting strip 7, so that even when subjected to pressure or impact force, the box body can still be kept from excessive denting or deformation; and there is further buffering of the folding piece 13. When bearing the impact force, the folding piece 13 will undergo tensile deformation, thereby slowing down the impact force. When the side wall of the box body is impacted, due to the setting of the protective frame 20, part of the impact force can be reduced while part of the impact force is converted into a thrust force, cooperating with the folding piece 13 to further resolve the impact force; when in use, the box body can also be used separately. The box cover 1 and the base 2 can be flipped open to hold fruits and vegetables, or the box cover 1 and the base 2 can be separated to hold fruits and vegetables separately. The storage plate 3 can be installed on the box cover 1 and the base 2 to hold eggs. After the box cover 1 and the base 2 are separated and cooperate with the storage plate 3, double the amount of egg products can be placed. The storage plate 3 can also be removed to hold fruits or wash fruits. The water flow and sundries during fruit washing can be discharged from the drain holes 18 of the box cover 1 or the base 2, which is more convenient to use and has stronger impact resistance, and can better protect the products in the box.

[0031] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
