Description

Technical Field

[0001] This invention relates to the field of packaging box technology, and more specifically, to a high-strength, pressure-resistant packaging box. Background Technology

[0002] Packaging boxes are used to package products, protect the packaged items, enhance the perceived quality of the packaged products, and ensure the safety of the products during transportation.

[0003] Most existing ceramic ware packaging boxes use bubble wrap, which involves sandwiching the ceramic ware between two pieces of bubble wrap to hold it in place and prevent damage during transportation. However, when using ceramic ware for display, due to its high fluidity, using disposable bubble wrap to hold it in place is problematic. The disposable bubble wrap is easily damaged when the ceramic ware is removed from the display, and after the ceramic ware has been displayed in one exhibition hall, it needs to be put back into the packaging box and transported to another exhibition hall. This requires replacing the disposable bubble wrap, causing significant inconvenience in the transportation of ceramic ware.

[0004] To address the aforementioned issues, existing technologies, such as CN113772221B, describe a high-strength pressure-resistant packaging box that uses a driving locking and pushing component to secure ceramic ware, allowing the packaging box to repeatedly secure the ceramic ware. However, when accessing the ceramic ware inside the packaging box, the aforementioned patent requires personnel to repeatedly open and close the locking and pushing component, making the use of the packaging box cumbersome and causing significant inconvenience to users. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a high-strength pressure-resistant packaging box that can automatically fix ceramics.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A high-strength pressure-resistant packaging box includes: a box body, wherein a box lid is hinged to the top wall of the box body;

[0008] The fixing mechanism includes a slide groove formed on the inner side wall of the box, a fixing plate is horizontally slidably installed in the slide groove, a threaded rod that is threadedly engaged with the fixing plate is rotatably installed on the side wall of the box, a first buffer pad is fixedly installed on the inner side wall of the box, and a second buffer pad is fixedly installed on the side of the fixing plate away from the threaded rod.

[0009] The driving mechanism includes a gear fixedly mounted on a threaded rod, a vertical groove is provided on the box body, a rack that meshes with the gear is slidably installed in the vertical groove, a first spring is fixedly installed between the bottom wall of the rack and the vertical groove, a first magnet is embedded in the rack, and a second magnet that repels the first magnet is fixedly installed on the box cover.

[0010] Furthermore, a horizontal groove is provided on the inner bottom wall of the box body, a placement plate is slidably installed in the horizontal groove, a third spring is fixedly installed between the placement plate and the horizontal groove, a linkage groove is provided on the placement plate, a spring telescopic rod is slidably installed in the linkage groove, and a fourth spring is fixedly installed between the spring telescopic rod and the linkage groove, and a fixing hole that mates with the lower end of the spring telescopic rod is provided in the horizontal groove.

[0011] Furthermore, air cylinders are symmetrically embedded on the inner sidewall of the box, a piston rod is slidably installed inside the air cylinder, a second spring is fixedly installed between the sidewall of the piston rod and the air cylinder, a clamping plate is fixedly installed at the end of the piston rod away from the second spring, and an air supply mechanism that cooperates with the air cylinder is provided on the first buffer pad.

[0012] Furthermore, the air supply mechanism includes a cavity formed on the second buffer pad, a first air pipe connected to a fixing hole is inserted into the bottom wall of the cavity, and a second air pipe connected to a fixing hole is inserted into the side wall of the air cylinder.

[0013] Furthermore, a sealing rod is slidably installed in the fixing hole, and a fifth spring is fixedly installed between the bottom wall of the sealing rod and the fixing hole. An annular groove that mates with the first air tube is provided on the lower end of the spring telescopic rod.

[0014] Furthermore, an air cavity is provided on the clamping plate, and air holes are evenly provided on the side wall of the air cavity. A connecting rod is slidably installed on the piston rod, and a sixth spring is fixedly installed between the connecting rod and the piston rod.

[0015] Furthermore, a telescopic tube is fixedly installed between the side wall of the piston rod and the air cylinder, and a connecting hole communicating with the air chamber is provided on the linkage rod.

[0016] Furthermore, a communication port is provided on the piston rod.

[0017] Furthermore, a fixing rod extending out of the vertical groove is inserted into the side wall of the vertical groove, and a seventh spring is fixedly installed between the fixing rod and the box body. The second magnet has a fixing opening that cooperates with the fixing rod, and the end of the second magnet away from the box cover is a slope.

[0018] Furthermore, the lower end of the spring telescopic rod is tapered.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) This solution uses the gear and rack to move the rack downwards under the repulsive force between the second magnet and the first magnet. Then, the rack, gear and threaded rod drive the fixing plate to fix the ceramic, thus effectively preventing damage during the transportation of the ceramic. In other words, the gear and rack do not require manual fixing of the ceramic, which improves the convenience of ceramic transportation and reduces the workload of users.

[0021] (2) This solution uses a spring telescopic rod. During the movement of the placement plate, the spring telescopic rod will move and the lower end of the spring telescopic rod will be inserted into the fixing hole. At this time, the placement plate is fixed under the action of the spring telescopic rod and the fixing hole, thus effectively preventing the ceramics from moving after the box lid is opened and causing the ceramics to shake and wear, which plays a role in protecting the ceramics.

[0022] (3) By setting up clamping plates, the second buffer pad will squeeze the second buffer pad during the process of the ceramic being brought into contact with the first buffer pad. Then the gas in the cavity flows into the two air cylinders through the first air pipe, the annular groove and the second air pipe, and causes the two clamping plates to move together toward the ceramic. During the movement of the clamping plates, they gradually come into contact with the ceramic and clamp the ceramic longitudinally, thus playing the role of longitudinally fixing the ceramic.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 8 A high-strength pressure-resistant packaging box includes a box body 1, and a box lid 2 is hinged to the top wall of the box body 1;

[0035] The fixing mechanism includes a sliding groove on the inner side wall of the box body 1, a fixing plate 3 is horizontally slidably installed in the sliding groove, a threaded rod 4 that is threadedly engaged with the fixing plate 3 is rotatably installed on the side wall of the box body 1, a first buffer pad 5 is fixedly installed on the inner side wall of the box body 1, and a second buffer pad 6 is fixedly installed on the side of the fixing plate 3 away from the threaded rod 4.

[0036] The driving mechanism includes a gear 7 fixedly mounted on a threaded rod 4. A vertical groove is provided on the box body 1. A rack 8 that meshes with the gear 7 is slidably mounted in the vertical groove. A first spring 9 is fixedly mounted between the bottom wall of the rack 8 and the vertical groove. A first magnet 10 is embedded in the rack 8. A second magnet 11 that repels the first magnet 10 is fixedly mounted on the box cover 2.

[0037] A horizontal groove is provided on the inner bottom wall of the box body 1. A placement plate 12 is slidably installed in the horizontal groove. A third spring 13 is fixedly installed between the placement plate 12 and the horizontal groove. A linkage groove is provided on the placement plate 12. A spring telescopic rod 14 is slidably installed in the linkage groove. A fourth spring 15 is fixedly installed between the spring telescopic rod 14 and the linkage groove. A fixing hole 16 is provided in the horizontal groove to cooperate with the lower end of the spring telescopic rod 14.

[0038] Initially, the first spring 9 is in a freely extended state. In use, first open the lid 2, then place the ceramic item on the top wall of the placement plate 12. After placing the ceramic item, close the lid 2. During the closing process of the lid 2, the second magnet 11 gradually enters the vertical groove. When the second magnet 11 enters the vertical groove, the distance between the second magnet 11 and the first magnet 10 reaches its minimum. At this point, the repulsive force on the first magnet 10 from the second magnet 11 reaches its maximum. Under the action of this repulsive force, the first magnet 10 drives the rack 8 to move downwards. At this time, the first spring 9 is compressed and has a tendency to return to its original position. During the downward movement of the rack 8, the gear 7 rotates, and during the rotation of the gear 7, the threaded rod 4 rotates. Due to the fixed plate... The fixed plate 3 slides against the inner wall of the box 1, meaning the fixed plate 3 cannot rotate. Then, as the threaded rod 4 rotates, it drives the fixed plate 3 to move along the threaded rod 4. During the movement of the fixed plate 3, the second buffer pad 6 gradually comes into contact with the ceramic, and the ceramic comes into contact with the first buffer pad 5. Then, under the combined action of the first buffer pad 5 and the second buffer pad 6, the ceramic is fixed, thus effectively preventing damage during the transportation of the ceramic. At the same time, by setting the placement plate 12, the placement plate 12 can be moved during the movement of the ceramic, thus preventing wear on the bottom wall of the ceramic. That is, through the cooperation of the gear 7 and the rack 8, there is no need for the user to manually fix the ceramic, which improves the convenience of ceramic transportation and reduces the workload of the user.

[0039] Furthermore, by using a metal box body 1, the strength and pressure resistance of the packaging box can be improved, thereby preventing damage to the ceramics. At the same time, by setting a first buffer pad 5 and a second buffer pad 6, when the box body 1 is collided with or squeezed by external objects, the first buffer pad 5 and the second buffer pad 6 can reduce the impact force on the ceramics, further improving the pressure resistance of the packaging box and playing a role in protecting the ceramics.

[0040] Initially, the third spring 13 is in a freely extended state. As the ceramic moves along the placement plate 12, the third spring 13 is stretched and tends to return to its original position. After the ceramic is transported to the designated location, the user can open the box cover 2. At this time, the box cover 2 causes the first magnet 10 to gradually move away from the second magnet 11, that is, the repulsive force of the second magnet 11 on the first magnet 10 gradually decreases. Then, the first spring 9 gradually extends and drives the rack 8 to reset upward. During the process of the rack 8 resetting upward, the threaded rod 4 is reversed through the gear 7. During the process of the threaded rod 4 resetting, the fixing plate 3 moves along the slide and resets. During the process of the fixing plate 3 resetting, the second buffer pad 6 gradually disengages from the ceramic. At this time, the third spring 13 contracts and drives the placement plate 12 to reset. Then, the user can take out the ceramic. When the user needs to transport the ceramic again, he only needs to put the ceramic back into the box 1 and close the box cover 2 to fix the ceramic again, that is, there is no need to replace the new packaging box.

[0041] Initially, the spring telescopic rod 14 and the fourth spring 15 are in a freely extended state. When the ceramic is placed on the top wall of the placement plate 12, the ceramic applies pressure to the spring telescopic rod 14, causing it to move downwards. The fourth spring 15 is compressed. Simultaneously, as the spring telescopic rod 14 moves downwards, its lower end contacts the horizontal groove, resulting in compression and a tendency to recover. Then, as the ceramic moves the placement plate 12, it moves the spring telescopic rod 14. When the lower end of the spring telescopic rod 14 passes the fixing hole 16, the spring telescopic rod 14... The lower end extends and inserts into the fixing hole 16. At this time, the placement plate 12 is fixed under the action of the spring telescopic rod 14 and the fixing hole 16. Then, after the ceramic is transported and the user takes it out, the lower end of the spring telescopic rod 14 extends. At the same time, the fourth spring 15 extends and drives the spring telescopic rod 14 to move upward. During the upward movement of the spring telescopic rod 14, it gradually disengages from the fixing hole 16. At this time, the third spring 13 contracts and drives the placement plate 12 to reset. That is, after the cover is opened, the placement plate 12 can only reset after the ceramic is taken out. This effectively protects the ceramic by preventing it from shaking and wearing after the box cover 2 is opened.

[0042] like Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8As shown, air cylinders 17 are symmetrically embedded on the inner sidewall of the box body 1. A piston rod 18 is slidably installed inside the air cylinder 17. A second spring 19 is fixedly installed between the sidewall of the piston rod 18 and the air cylinder 17. A clamping plate 20 is fixedly installed at the end of the piston rod 18 away from the second spring 19. An air supply mechanism that cooperates with the air cylinder 17 is provided on the first buffer pad 5.

[0043] The air supply mechanism includes a cavity 21 opened on the second buffer pad 6, a first air pipe 22 connected to the fixing hole 16 is inserted into the bottom wall of the cavity 21, and a second air pipe 23 connected to the fixing hole 16 is inserted into the side wall of the air cylinder 17.

[0044] A sealing rod 24 is slidably installed in the fixing hole 16. A fifth spring 25 is fixedly installed between the bottom wall of the sealing rod 24 and the fixing hole 16. An annular groove 26 that mates with the first air pipe 22 is provided on the lower end of the spring telescopic rod 14.

[0045] The clamping plate 20 has an air chamber 27, and air holes are evenly distributed on the side wall of the air chamber 27. A connecting rod 28 is slidably installed on the piston rod 18, and a sixth spring 29 is fixedly installed between the connecting rod 28 and the piston rod 18.

[0046] A telescopic tube 30 is fixedly installed between the side wall of the piston rod 18 and the air cylinder 17, and a connecting hole 31 communicating with the air chamber 27 is provided on the connecting rod 28.

[0047] The piston rod 18 has a communication port 32.

[0048] By adopting the above technical solution, initially, the second spring 19 is in a freely extended state, and at this time, the lower end of the spring telescopic rod 14 is not inserted into the fixing hole 16, that is, the fifth spring 25 is in a freely extended state. Then, during the process of the second buffer pad 6 driving the ceramic to contact the first buffer pad 5, the second buffer pad 6 will be squeezed due to the resistance of the ceramic. Then, the gas pressure in the cavity 21 will increase and tend to flow outward. Then, during the process of the lower end of the spring telescopic rod 14 being inserted into the fixing hole 16, the sealing rod 24 will move downward. At this time, the fifth spring 25 will be compressed and tend to recover. That is, the lateral fixation of the ceramic has ended. Then, the spring telescopic rod 14... During the process of inserting the lower end into the fixing hole 16, the lower end of the spring telescopic rod 14 drives the annular groove 26 to gradually contact the first air pipe 22. At this time, the first air pipe 22 is connected to the second air pipe 23 through the annular groove 26. Then, the gas in the cavity 21 flows into the two air cylinders 17 through the first air pipe 22, the annular groove 26, and the second air pipe 23, which increases the pressure in the two air cylinders 17. Then, under the action of pressure, the two piston rods 18 drive the two clamping plates 20 to move together towards the ceramic. At this time, the second spring 19 is stretched and has a tendency to return to its original state. During the movement of the clamping plate 20, it gradually contacts the ceramic and clamps the ceramic longitudinally, which plays the role of fixing the ceramic longitudinally.

[0049] Initially, the sixth spring 29 is in a freely extended state. During the movement of the piston rod 18 driven by the gas pressure inside the air cylinder 17, the space on the side of the air cylinder 17 furthest from the clamping plate 20 by the telescopic tube 30 can be reduced, thereby increasing the intensity of the gas pressure. Furthermore, during the movement of the piston rod 18 driven by the pressure, the telescopic tube 30 is stretched, and the pressure inside the telescopic tube 30 decreases. As the clamping plate 20 approaches the ceramic, it causes the connecting rod 28 to gradually contact the ceramic. Then, under the resistance of the ceramic, the connecting rod 28 moves into the telescopic tube 30. At this time, the sixth spring 29... The six springs 29 are stretched and have a tendency to return to their original state. During the movement of the linkage rod 28, the connecting hole 31 is moved. When the clamping plate 20 is in contact with the ceramic, the linkage rod 28 drives the connecting hole 31 to connect with the telescopic tube 30. At this time, the telescopic tube 30 draws air from the air chamber 27 through the connecting hole 31, which reduces the pressure in the air chamber 27. Then, under the action of pressure, the air chamber 27 has a tendency to draw air from the outside through the air hole. Since the clamping plate 20 is in contact with the ceramic at this time, that is, the ceramic is in contact with the air hole, and then under the action of pressure, the clamping plate 20 and the ceramic are tightly attracted together, thereby improving the fixing effect of the ceramic.

[0050] During the process of the piston rod 18 driving the clamping plate 20 to fix the ceramic, the gas pressure in the space of the air cylinder 17 located on the side of the piston rod 18 near the clamping plate 20 increases. The clamping plate 20 drives the connecting rod 28 to gradually contact the ceramic. Then, under the action of the resistance of the ceramic, the connecting rod 28 gradually moves towards the telescopic tube 30. During the movement of the connecting rod 28, the connecting hole 31 gradually contacts the connecting port 32. Then, under the action of pressure, the gas in the space of the air cylinder 17 located on the side of the piston rod 18 near the clamping plate 20 is blown onto the surface of the ceramic through the connecting port 32, the connecting hole 31, the air chamber 27, and the air hole. This can clean the dust on the surface of the ceramic, making it easier for the clamping plate 20 to adhere tightly to the ceramic, thus improving the fixing effect of the ceramic.

[0051] When the lid 2 is opened, the fixing plate 3 causes the second buffer pad 6 to gradually detach from the ceramic. At this time, the second buffer pad 6 gradually extends, and the pressure in the cavity 21 decreases. Then, under the action of pressure, the cavity 21 draws air from the space in the air cylinder 17 located on the side of the piston rod 18 near the telescopic tube 30 through the first air pipe 22, the annular groove 26, and the second air pipe 23. Then, the pressure in the space in the air cylinder 17 located on the side of the piston rod 18 near the telescopic tube 30 gradually returns to normal. At this time, the second spring 19 contracts and drives the piston rod 18 to reset. During the process of the piston rod 18 resetting, the telescopic tube 30 is compressed. During the process of the piston rod 18 resetting, the clamping plate 20 gradually detaches from the ceramic. At this time, the sixth spring 29 gradually contracts and drives the connecting rod 28 to reset, which serves to prepare for the next operation.

[0052] like Figure 1 , Figure 3 , Figure 6 As shown, a fixing rod 33 extending out of the vertical groove is inserted into the side wall of the vertical groove, and a seventh spring 34 is fixedly installed between the fixing rod 33 and the box body 1. The second magnet 11 has a fixing port 35 that cooperates with the fixing rod 33, and the end of the second magnet 11 away from the box cover 2 is a slope.

[0053] By adopting the above technical solution, in the initial state, the seventh spring 34 is in a freely extended state. During the closing process of the lid 2, it drives the second magnet 11 to gradually insert into the vertical groove. During the insertion of the second magnet 11 into the vertical groove, the inclined surface of the second magnet 11 gradually contacts the fixing rod 33 and applies a pushing force to the fixing rod 33. Then, under the action of the pushing force, the fixing rod 33 moves out of the vertical groove and stretches the seventh spring 34. Then, during the insertion of the second magnet 11 into the vertical groove, it drives the fixing opening 35 to gradually contact the fixing rod 33. At this time, the seventh spring 34 retracts and drives the fixing rod 33 to insert into the fixing opening 35. Then, under the action of the fixing rod 33, the lid 2 is fixed. Then, under the action of the lid 2, the ceramic can be fixed in the vertical direction, which improves the fixing effect of the lid 2.

[0054] When it is necessary to open the lid 2, the user can pull the fixing rod 33 and disengage the fixing rod 33 from the fixing opening 35. Then the user can push the lid 2 upward and make the lid 2 rotate around the hinge point, which facilitates the user to open the lid 2.

[0055] like Figure 8 As shown, the lower end of the spring telescopic rod 14 is tapered.

[0056] By adopting the above technical solution, during the process of the lower end of the spring telescopic rod 14 extending and being inserted into the fixing hole 16, by making the lower end of the spring telescopic rod 14 tapered, the initial contact area between the lower end of the spring telescopic rod 14 and the fixing hole 16 can be reduced, thereby facilitating the insertion of the rod into the fixing hole 16, and playing the role of facilitating the insertion of the lower end of the spring telescopic rod 14 into the fixing hole 16.

[0057] Instructions for use: First, open the lid 2. Then, place the ceramic on the top wall of the placement plate 12. After placing the ceramic, close the lid 2. As the lid 2 closes, the second magnet 11 gradually enters the vertical groove. Under the action of repulsion, the first magnet 10 drives the rack 8 downward. At this time, the first spring 9 is compressed and has a tendency to return to its original position. As the rack 8 moves downward, it drives the gear 7 to rotate. As the gear 7 rotates, it drives the threaded rod 4 to rotate. Since the fixed plate 3 slides against the inner wall of the box body 1, the fixed plate 3 cannot rotate. As the threaded rod 4 rotates, it drives the fixed plate 3 to move along the threaded rod 4. As the fixed plate 3 moves, it drives the second buffer pad 6 to gradually contact the ceramic, and then drives the ceramic to contact the first buffer pad 5. Then, the first buffer pad 5 and the second buffer pad 6 gradually come into contact. Under the combined action of pads 6, the ceramic is fixed; during the process of the second buffer pad 6 bringing the ceramic into contact with the first buffer pad 5, the second buffer pad 6 will be squeezed due to the resistance of the ceramic. Then, during the process of the lower end of the spring telescopic rod 14 being inserted into the fixing hole 16, the lower end of the spring telescopic rod 14 will bring the annular groove 26 into contact with the first air pipe 22. At this time, the first air pipe 22 is connected to the second air pipe 23 through the annular groove 26. Then, the gas in the cavity 21 flows into the two air cylinders 17 through the first air pipe 22, the annular groove 26, and the second air pipe 23, which increases the pressure in the two air cylinders 17. Then, under the action of the pressure, the two piston rods 18 will bring the two clamping plates 20 together to move towards the ceramic. At this time, the second spring 19 is stretched and has a tendency to recover. During the movement of the clamping plates 20, they gradually come into contact with the ceramic and clamp the ceramic longitudinally.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
