Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a shockproof packaging box. Background Art

[0002] A packaging box is a type of carrying container used in various fields of packaging and transportation, such as the metal field, environmental protection field, medical field, etc. They are usually made of various materials, including plastic, metal, etc. The specific material selection depends on factors such as the nature, weight and mode of transportation of the packaged items. The design of the packaging box usually takes into account factors such as the safety of the items, transportation efficiency, stacking stability and packaging cost. They play an important role in the supply chain to protect goods from damage and contamination.

[0003] At present, an existing device (such as patent number: CN219447658U) discloses a "packaging box", which reduces the space occupied during transportation by setting the packaging box as a foldable structure, and adjusts the size of the packaging box according to different needs by setting the bottom plate and the first side plate as a telescopic structure, thereby reducing the management cost and meeting the needs of different daily use scenarios, and has strong practicality;

[0004] However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: during transportation, due to complex road conditions, once the device encounters a bumpy road, the car body will tilt and vibrate. Since the above device is not equipped with a shock absorbing mechanism, the workpieces in the packaging box are easily damaged when encountering a bumpy road, and the practicality needs to be improved. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a shockproof packaging box, which solves the technical problem that the prior devices are insufficiently practical.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A shockproof packaging box, comprising a packaging box body and a cover plate, wherein the cover plate is hinged to the upper part of the packaging box body;

[0010] The inner wall of the packaging box body is symmetrically and fixedly installed with a shock-absorbing and limiting mechanism;

The two rotating shafts are fixedly installed with the inner rings of the damping bearings. An annular part is fixedly installed on the circumferential surfaces of the two damping bearings. The inner rings of the two damping bearings are fixedly installed with the annular part. The shock-absorbing and limiting mechanism also includes a storage box, an arc-shaped side plate, a slide groove, a friction layer, a slider, and a friction plate.

[0012] Preferably: the storage box is located between the annular members, the storage box is fixedly mounted to the annular members, the two arcuate side panels are located on the inner wall of the packaging box body, the two arcuate side panels are fixedly mounted to the packaging box body, and the two arcuate side panels are located on both sides of the storage box; each group of the slide grooves is opened inside the arcuate side panels, the two friction layers are located at opposite ends of the arcuate side panels, the two friction layers are fixedly mounted to the arcuate side panels, and the two friction layers are located between the slide grooves.

[0013] Preferably: each of the sliders is located inside the slide groove, each group of the sliders is slidably mounted on the slide groove, the two friction plates are located between the sliders, the two friction plates are fixedly mounted on the sliders, each friction plate is in contact with the friction layer, and each of the sliders is fixedly mounted on the storage box.

[0014] Preferably, dampers are symmetrically fixedly installed inside the packaging box body, extrusion blocks are fixedly installed on two damper pistons, each of the extrusion blocks is adapted to the storage box, and handles are symmetrically fixedly installed on the side walls of the packaging box body.

[0015] (III) Beneficial effects

[0016] 1. By setting up a storage box, when the packaging box body vibrates, it can drive the annular member to rotate to a certain extent with the damping bearing as the center of the circle, so that the storage box drives the slider on one side to move downward in the slide groove, and the slider on the other side will move upward in the slide groove, converting the vibration force that originally directly acts on the packaging box body into a sliding force. At the same time, the damping bearing will provide a certain degree of damping, thereby preventing excessive vibration, avoiding damage to the environmental protection bowl inside the storage box, and improving practicality.

[0017] Second, when the packaging box body vibrates, the storage box will rotate to a certain extent with the damping bearing as the center, so the storage box will drive the slider on one side to move downward in the slide groove, and the slider on the other side will move upward in the slide groove, and when the slider moves, the friction plate and the friction layer will rub against each other, thereby generating a certain resistance, thereby converting the sliding force converted by the vibration into friction heat energy, thereby reducing the overall movement of the storage box and further improving the shockproof effect. At the same time, by setting the damper, when the storage box tilts to squeeze the extrusion block on the piston of the damper, the damper can provide an additional resistance and can also assist the storage box to reset and return to a horizontal state.

[0024] The embodiment of the present application provides a shockproof packaging box, which effectively solves the technical problem of insufficient practicality of the existing device. By setting up a storage box, when the packaging box body vibrates, it can drive the annular member to rotate a certain amplitude with the damping bearing as the center of the circle, so that the storage box drives the slider on one side to move downward in the slide groove, and the slider on the other side will move upward in the slide groove, converting the vibration force that originally directly acts on the packaging box body into a sliding force. At the same time, the damping bearing will perform a certain degree of damping, thereby preventing excessive vibration, avoiding damage to the environmental protection bowl inside the storage box, improving practicality, and when the packaging box body vibrates When the sliding plate moves, the sliding plate and the friction layer will rub against each other, thereby generating a certain resistance, thereby converting the sliding force converted from the vibration into friction heat energy, thereby reducing the overall movement of the glove box and further improving the shockproof effect. At the same time, by setting the damper, when the glove box tilts and squeezes the extrusion block on the piston of the damper, the damper can provide an additional resistance and can also assist the glove box in resetting and returning to a horizontal state.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient practicality of the existing device, and the overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a shockproof packaging box, comprising a packaging box body 11 and a cover plate 12, wherein the cover plate 12 is hinged to the upper part of the packaging box body 11;

[0028] A shock-absorbing and limiting mechanism is symmetrically fixedly installed on the inner wall of the packaging box body 11;

[0029] The shock-absorbing and limiting mechanism includes a rotating shaft 13, and damping bearings 14 are fixedly installed on the circumferential surfaces of the two rotating shafts 13. The two rotating shafts 13 are fixedly installed with the inner rings of the damping bearings 14. The circumferential surfaces of the two damping bearings 14 are fixedly installed with annular members 15, and the inner rings of the two damping bearings 14 are fixedly installed with the annular members 15. The shock-absorbing and limiting mechanism also includes a storage box 16, an arcuate side plate 17, a slide groove 18, a friction layer 19, a slider 21, and a friction plate 22. The storage box 16 is located between the annular members 15, and the storage box 16 is fixedly installed with the annular member 15. The two arcuate side plates 17 are located on the inner wall of the packaging box body 11, and the two arcuate side plates 17 are fixedly installed with the packaging box body 11. The two arcuate side plates 17 are located on both sides of the storage box 16, and each group of slide grooves 18 is opened on the arc Inside the arc-shaped side plate 17, the two friction layers 19 are located at the opposite ends of the arc-shaped side plate 17, and the two friction layers 19 are fixedly installed with the arc-shaped side plate 17. The two friction layers 19 are located between the slide grooves 18. By arranging the storage box 16, when the packaging box body 11 vibrates, it can drive the annular member 15 to rotate a certain amplitude with the damping bearing 14 as the center of the circle, so that the storage box 16 drives the slider 21 on one side to move downward in the slide groove 18, and the slider 21 on the other side will move upward in the slide groove 18, converting the vibration force that originally directly acts on the packaging box body 11 into a sliding force. At the same time, the damping bearing 14 will perform a certain degree of damping, thereby preventing excessive vibration, avoiding damage to the environmental protection bowl inside the storage box 16, and improving practicality.

[0030] Each slider 21 is located inside the slide groove 18, each group of sliders 21 is slidably installed with the slide groove 18, two friction plates 22 are located between the sliders 21, two friction plates 22 are fixedly installed with the sliders 21, each friction plate 22 is in contact with the friction layer 19, each slider 21 is fixedly installed with the storage box 16, dampers 23 are symmetrically fixedly installed inside the packaging box body 11, and extrusion blocks 24 are fixedly installed on the pistons of the two dampers 23, and each extrusion block 24 is adapted to the storage box 16, and handles 25 are symmetrically fixedly installed on the side walls of the packaging box body 11. When the packaging box body 11 vibrates, the storage box 16 will move a certain amplitude around the damping bearing 14 as the center of the circle. The sliding plate 22 and the friction layer 19 will rub against each other when the sliding plate 21 moves, thereby generating a certain resistance, thereby converting the sliding force converted from the vibration into friction heat energy, thereby reducing the overall movement amplitude of the glove box 16 and further improving the shockproof effect. At the same time, by providing the damper 23, when the glove box 16 tilts and squeezes the extrusion block 24 on the piston of the damper 23, the damper 23 can provide an additional resistance and can also assist the glove box 16 in resetting and returning to a horizontal state.

[0031] Working principle:

[0032] In the first step, when using, the cover plate 12 of the packaging box body 11 and the storage box 16 can be opened first, and then the environmentally friendly bowls can be stacked in the storage box 16. When the stacking is completed, the storage box 16 and the cover plate 12 can be closed. At this time, the staff can use the handle 25 to move the packaging box body 11 as a whole and carry it to the truck;

[0033] In the second step, when the truck encounters a pothole during driving, the truck as a whole will tilt and vibrate. At this time, the packaging box body 11 will tilt to one side, and the storage box 16 will drive the annular member 15 to rotate a certain amplitude around the damping bearing 14 as the center of the circle. Therefore, the storage box 16 will drive the slider 21 on one side to move downward in the slide groove 18, and the slider 21 on the other side will move upward in the slide groove 18. When the slider 21 moves, the friction plate 22 will rub against the friction layer 19, thereby generating a certain resistance. When the storage box 16 on one side moves downward, the bottom of the storage box 16 will first contact the extrusion block 24, causing the extrusion block 24 to generate a downward radial force, thereby compressing the piston of the damper 23, causing the damper 23 to damp and avoid excessive shaking.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
