Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a crush-resistant packaging box. Background Technology

[0002] Packaging boxes, as the name suggests, are boxes used to package products. They can be classified by material, such as: paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, and corrugated packaging boxes. Merchants generally use packaging boxes to package some items. When packaging items, a crush-resistant packaging box is needed.

[0003] Most existing packaging boxes lack effective protective structures. Currently, the common method to improve the pressure resistance of packaging boxes is to install support frames inside the box. While this method can effectively improve the pressure resistance, the sides of the box remain relatively fragile. When objects in the external environment accidentally impact or squeeze the sides of the box, the force generated during the impact or squeeze may still cause deformation of the sides, thus affecting the normal use of the box and the contents inside, reducing the overall practicality and strength of the packaging box.

[0004] Compared with the packaging box with good compression resistance disclosed in application number CN219905095U, the packaging box includes a cover plate rotatably connected to the front and rear sides of the upper end of the packaging box. The four sides of the paper packaging box are supported by the set connecting rod, first support rod, fixed rod and main support rod, and the upper end of the packaging box is supported by the support component to reduce the deformation of the packaging box and the deformation of the inner items.

[0005] The above solution can support the top surface of the packaging box, but it still does not have an effective structure to protect the sides of the packaging box. When the sides of the packaging box are impacted, the sides of the packaging box may still deform, thus affecting the normal use of the packaging box.

[0006] Based on this, a crush-resistant packaging box is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In one embodiment, such as Figures 1-5 As shown, a crush-resistant packaging box includes a box body 1, and a closing lid 2 is fitted onto the outer wall of the box body 1;

[0034] The fixing components are symmetrically arranged on the surface of the closing cover 2 and are used to fix the closing cover 2 to the box body 1;

[0035] Support components are respectively installed on the inner walls of the box body 1 and the closing lid 2, and are used to improve the overall compressive strength of the packaging box;

[0036] The protective components are located on the outside of the housing 1 and are used to protect both sides of the housing 1.

[0037] In this embodiment, when it is necessary to transport items, simply place the items inside the box 1, and then use the fixing components to close and fix the closing cover 2 to the box 1. At this time, the items can be effectively transported. By setting the support components, the support strength of the box 1 and the closing cover 2 can be effectively improved, thereby effectively improving the overall support strength of the device and reducing the probability of deformation of the device. When an object in the external environment accidentally hits or squeezes the side of the box 1, the protective components can effectively buffer the force generated by the impact or squeeze, thereby effectively protecting the side of the box 1 and preventing deformation of the side of the box 1, further improving the overall strength and service life of the device.

[0038] In one embodiment, such as Figure 2 and Figure 4 As shown, the fixing assembly includes fixing plates 8 symmetrically mounted on the surface of the closing cover 2. Slide rods 9 are symmetrically mounted on the inner wall of the fixing plates 8. A contact plate 10 is slidably connected to the outer wall of every two slide rods 9. A return spring 11 is sleeved on the outside of each slide rod 9, and the return spring 11 abuts against the contact plate 10 and the fixing plate 8. A pull ring is fixedly connected to one side of the contact plate 10 via a side plate 12. Insert rods 13 are symmetrically mounted on the other side of the contact plate 10. Slots for the insertion rods 13 are provided on the contact surfaces of the fixing plate 8 and the closing cover 2, as well as on the surface of the box body 1. When it is necessary to close the closing cover 2 and the box body 1... When fixing, simply pull the pull ring first. The pull ring will drive the side plate 12 to move synchronously. The side plate 12 will then drive the contact plate 10 to move synchronously on the outer wall of the slide rod 9. During the movement of the contact plate 10, it will squeeze the return spring 11. The contact plate 10 will also drive the insertion rod 13 to move synchronously. Then, put the closing cover 2 on the outer wall of the box body 1 and release the pull ring. At this time, the return spring 11 will return to its original position, driving the contact plate 10 and the insertion rod 13 to move synchronously. When the insertion rod 13 is inserted into the slot on the surface of the box body 1, the closing cover 2 and the box body 1 can be closed and fixed.

[0039] In one embodiment, such as Figure 3 As shown, the support assembly includes a first support frame 5 and a second support frame 6, which are respectively fixedly installed on the inner wall of the box 1 and the inner wall of the closed cover 2. By setting the first support frame 5 and the second support frame 6, the overall support strength of the device can be effectively improved, thereby reducing the probability of deformation of the device.

[0040] In one embodiment, such as Figure 1 , Figure 2 and Figure 5 As shown, the protective assembly includes protective plates 3 symmetrically arranged on the outside of the box 1. Support plates 7 are symmetrically mounted on the surface of the first support frame 5. Connecting plates 14 are symmetrically mounted on the surface of the support plates 7. An inner rod 15 is fixedly connected to the inner wall of the connecting plate 14. Sliding blocks 16 are symmetrically slidably connected to the outer wall of the inner rod 15. A groove is provided on the surface of the connecting plate 14 for the sliding blocks 16 to move. A hinge block 19 is hinged to the surface of each pair of sliding blocks 16 via a connecting rod 18. A force spring 17 is sleeved on the outside of the inner rod 15. The two ends of the force spring 17 are fixedly connected to the opposite side of each pair of sliding blocks 16. A movable plate 20 is fixedly connected to the surface of the hinge block 19. The surfaces of each pair of movable plates 20 are fixedly connected to the surfaces of the two protective plates 3. When an object in the external environment accidentally impacts or squeezes the side of the box 1, the impact or squeezing produces... The force generated will cause the protective plate 3 to shift. At this time, the protective plate 3 will drive the moving plate 20 to move synchronously. The moving plate 20 will then drive the hinge block 19 to move synchronously. Since the hinge block 19 and the slider 16 are hinged by the connecting rod 18, the hinge block 19 will drive the slider 16 to move synchronously on the outer wall of the inner rod 15 through the connecting rod 18. During the movement of the slider 16, the force spring 17 will be stretched. At this time, the force spring 17 can effectively distribute the force generated by the impact or compression, thereby converting the force into elastic potential energy and prolonging the action time of the force. This can effectively reduce the magnitude of the impact force directly acting on the box 1, and can effectively cooperate with the protective plate to protect the box 1, avoid damage to the box 1 due to excessive impact, and effectively extend the service life of the box 1.

[0041] In one embodiment, such as Figure 2 and Figure 5 As shown, damping rods 23 are symmetrically installed on both sides of the support plate 7. The telescopic ends of every two damping rods 23 are fixedly connected to the surface of the moving plate 20. By setting the damping rods 23, the elastic potential energy of the component spring 17 can be effectively limited, thereby avoiding the component spring 17 from repeatedly rebounding and affecting the protective effect of the protective plate 3 on the side of the box 1.

[0042] In one embodiment, such as Figures 1-3As shown, bellows protective covers 4 are fixedly connected to both sides of the support plate 7. The other end of the bellows protective cover 4 is fixedly connected to the surface of the moving plate 20. By setting the bellows protective cover 4, the damping rod 23 and the force spring 17 and other components can be effectively protected, thereby effectively extending the service life of the damping rod 23 and the force spring 17 and other components, while not affecting the normal use effect of the damping rod 23 and the force spring 17 and other components.

[0043] In one embodiment, such as Figure 2 and Figure 5 As shown, fixing blocks 24 are fixedly connected to both the upper and lower surfaces of the support plate 7. A guide rod 21 is fixedly installed inside the fixing block 24. Limiting discs 22 are fixedly connected to both ends of the guide rod 21. A guide groove for the guide rod 21 to move is opened through the surface of the moving plate 20. Through the setting of the guide rod 21 and the limiting disc 22, the moving plate 20 can be effectively limited and guided, thereby effectively improving the stability of the moving plate 20 during movement, and thus effectively improving the stability of the protective plate 3 during movement, and further improving the protective effect of the protective plate 3 on the side of the box 1.

[0044] In one embodiment, such as Figures 1-5 As shown, the multiple return springs 11 and force springs 17 are all made of stainless steel. Stainless steel has good corrosion resistance, so the return springs 11 and force springs 17 also have good corrosion resistance, which can further extend the service life of the return springs 11 and force springs 17.

[0045] The above embodiment discloses a crush-resistant packaging box. When it is necessary to transport items, the items are placed in the box body 1 first, and then the closing cover 2 is closed and fixed to the box body 1 by the cooperation between the pull ring and the insertion rod 13. At this time, the items can be effectively transferred. The setting of the first support frame 5 and the second support frame 6 can effectively improve the support strength of the box body 1 and the closing cover 2, thereby effectively improving the overall support strength of the device and reducing the probability of deformation of the device. When an object in the external environment accidentally hits or squeezes the side of the box body 1, the protective plate 3 and the force spring 17 can effectively buffer the force generated by the impact or squeeze, thereby effectively protecting the side of the box body 1 and avoiding deformation of the side of the box body 1, further improving the overall strength and service life of the device.

[0046] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
