However, the road conditions or equipment carrying the packaging often vary depending on the destination, resulting in different vibrations, such as different amplitudes or vibration frequencies. In actual operation, resonance should be avoided, which requires the design of a damping and shock absorption structure that can dynamically adjust to various vibration frequencies to adapt to different road conditions. Summary of the Invention

[0003] To address the aforementioned problems in the prior art, the present invention provides the following solution:

[0004] A liquid pharmaceutical packaging with good cushioning performance includes a liquid bottle, a cushioning device, a packaging box, and cushioning plates. Multiple cushioning plates are arranged inside the packaging box, and these plates are joined to form a receiving section for accommodating the liquid bottle. A cushioning device is located at the lower end of the liquid bottle. The cushioning device includes a connecting part, an upper liquid chamber, a middle part, a lower liquid chamber, an upper elastic layer, and a lower elastic layer. The connecting part, upper elastic layer, middle part, and lower elastic layer are connected sequentially from top to bottom. The connecting part is connected to the bottom of the liquid bottle, and the middle part is connected to the cushioning plates. The middle part is a... A damping disc has an annular damping channel on its inner outer periphery. The upper end of the upper elastic layer is connected to the connecting part 2.4, the lower end of the upper elastic layer is connected to the middle part, and the upper end of the lower elastic layer is connected to the middle part. The connecting part, the middle part, and the upper elastic layer form an upper liquid chamber, and the middle part and the lower elastic layer form a lower liquid chamber. The annular damping channel is provided with an adjustable damping flow path. The upper liquid chamber and the lower liquid chamber are connected through the annular damping channel. The connecting part includes a horizontal plate, and a suction nozzle is provided in the middle of the horizontal plate. The suction nozzle can cooperate with the recess at the bottom of the liquid bottle to fix the liquid bottle.

[0005] Furthermore, the buffer plates are spliced ​​to form a recess for accommodating the buffer device. The buffer plates are provided with slots, and the outer side of the middle part is provided with protrusions, which are locked inside the slots.

[0006] Furthermore, a flow channel is provided at the bottom of the suction nozzle. The nozzle is connected to the horizontal plate through a flexible rotating part. The flow channel passes through the flexible rotating part and enters the interior of the horizontal plate. It extends horizontally along the horizontal plate to the outside of the buffer device and is connected to the air pump.

[0007] Furthermore, a baffle is provided on the inner wall of the annular damping flow channel. A through hole one is provided on the baffle, and an annular groove is provided inside the baffle. An annular adjusting plate is provided inside the annular groove. The annular adjusting plate is driven by a driving mechanism to slide along the annular groove, thereby realizing the rotation of the annular adjusting plate. A through hole two is provided on the annular adjusting plate. Through hole one and through hole two form an adjustable damping flow path.

[0008] Furthermore, through hole two includes multiple sets of different hole diameters. By rotating the annular adjusting plate 2.12 at different angles, through hole one can be matched with through hole two of different diameter sets, thereby achieving different damping and vibration reduction states.

[0009] Furthermore, a tapered transition section is provided at the end of the second through hole, realizing the transition from the size of the first through hole to the size of the second through hole.

[0010] Furthermore, a second damping mechanism is provided in the center of the damping disk. The second damping mechanism is located inside the annular damping flow channel and includes an upper adjustment hole layer, a lower adjustment hole layer, and a middle elastic layer. The center of the damping disk has a three-layer structure: the upper adjustment hole layer, the middle elastic layer, and the lower adjustment hole layer.

[0011] Furthermore, the upper adjustment hole layer includes a rotatable upper hole layer and a stationary upper hole layer. The rotatable upper hole layer is located above the stationary upper hole layer. The rotatable upper hole layer and the stationary upper hole layer are rotatably connected around the rotation center. The power mechanism drives the rotatable upper hole layer to rotate. The rotatable upper hole layer and the stationary upper hole layer are provided with the same number of through holes in the same position.

[0012] Furthermore, the lower adjustment hole layer includes a rotatable lower hole layer and a stationary lower hole layer. The rotatable lower hole layer is located below the stationary lower hole layer. The rotatable lower hole layer and the stationary lower hole layer are rotatably connected around the rotation center. The power mechanism two drives the rotatable lower hole layer to rotate. The rotatable lower hole layer and the stationary lower hole layer are provided with the same number and the same position of through holes four.

[0013] Furthermore, the intermediate elastic layer comprises multiple annular layers with different stiffnesses, the stiffness decreasing towards the center of the circle along the diameter direction.

[0014] Furthermore, vertical sections are provided on the left and right sides of the connecting part, and multiple grooves are provided on the inner side of the vertical sections, with adsorption sections provided in the grooves.

[0015] Furthermore, the adsorption part includes a flexible hinge part, the top of which is connected to a flexible L-shaped adhesive part, the length of the horizontal part of the L-shaped adhesive part being greater than the length of the vertical part.

[0016] Furthermore, multiple mass blocks are arranged on the intermediate elastic layer.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention uses conventional buffer plates, such as corrugated paper or other types of boards, combined with a hydraulic damping structure to achieve damping and shock reduction, thereby achieving a better shock reduction effect.

[0019] 2. The buffer structure of this application adopts an upper liquid chamber and a lower liquid chamber, and sets up an annular damping channel and an elastic layer in the center to achieve dual shock absorption, thereby realizing multi-frequency and multi-amplitude shock absorption, thus having a better shock absorption effect.

[0020] 3. Based on the above structure, the present invention also includes an annular adjustment plate to enable the matching of through hole one with different through holes two, thereby achieving the adjustment of damping performance. This allows for optimal vibration reduction by adjusting the appropriate damping performance according to different working conditions, amplitudes, and vibration frequencies.

[0021] 4. The overlap between the rotatable upper perforation layer and the stationary upper perforation layer can be adjusted, thereby regulating the flow area of ​​the damping fluid. Adjusting the damping area controls the flow rate of the damping fluid and thus the damping effect.

[0022] 5. The deformability of the nozzle edge allows for adsorption to pits of different shapes, increasing the convenience of fixation. It can also reduce the pull-out force of the liquid bottle 1 by injecting gas to contact the suction of the nozzle. The L-shaped fitting part rotates around the flexible hinge part, and finally achieves adsorption to the liquid bottle 1 through the deformation of the horizontal and vertical parts of the L-shaped fitting part, thereby achieving simple auxiliary fixation.

[0023] 6. Multiple mass blocks are set on the intermediate elastic layer, which can absorb vibration while working together with the elastic layer and mass blocks to reduce shock. Attached Figure Description

[0031] See Figure 1-7 This invention relates to a liquid pharmaceutical packaging with good cushioning performance, comprising a liquid bottle 1, a cushioning device 2, a packaging box 3, and cushioning plates 4. Multiple cushioning plates 4 are disposed inside the packaging box 3, and the cushioning plates 4 are spliced ​​to form a receiving portion for accommodating the liquid bottle 1. A cushioning device 2 is disposed at the lower end of the liquid bottle 1. The cushioning device includes a connecting part 2.4, an upper liquid chamber 2.1, a middle part 2.2, a lower liquid chamber 2.3, an upper elastic layer 2.6, and a lower elastic layer 2.7. The connecting part 2.4, upper elastic layer 2.6, middle part 2.2, and lower elastic layer 2.7 are connected sequentially from top to bottom. The connecting part 2.4 is connected to the bottom of the liquid bottle 1, and the middle part 2.2 is connected to the cushioning plates 4. The middle part 2.2 is a damping element. The damping disc has an annular damping channel 2.5 on its outer periphery. The upper elastic layer 2.6 is connected to the connecting part 2.4 at its upper end and to the middle part 2.2 at its lower end. The lower elastic layer 2.7 is connected to the middle part 2.2 at its upper end. The connecting part 2.4, the middle part 2.2, and the upper elastic layer 2.6 form the upper liquid chamber 2.1. The middle part 2.2 and the lower elastic layer 2.7 form the lower liquid chamber 2.3. The annular damping channel 2.5 is provided with an adjustable damping flow path. The upper liquid chamber 2.1 and the lower liquid chamber 2.3 are connected through the annular damping channel 2.5. The connecting part 2.4 includes a horizontal plate. A suction nozzle 2.8 is provided in the middle of the horizontal plate. The suction nozzle 2.8 can cooperate with the recess at the bottom of the liquid bottle 1 to fix the liquid bottle 1. The above-described structure allows the liquid bottle 1 in conventional liquid pharmaceutical packaging to have a recess at its bottom to ensure stability. To fully utilize the original structure of the liquid bottle 1 and avoid increasing costs by adding new fitting structures, the liquid bottle 1 is fixed by using a suction nozzle 2.8 structure in conjunction with the recess structure. The upper and lower liquid chambers allow the damping fluid to flow between them and absorb vibrations from the liquid bottle 1 through an adjustable damping flow path, preventing breakage. At the same time, the upper elastic layer 2.6 and the lower elastic layer 2.7 can also absorb the vibrations of the damping fluid.

[0032] Furthermore, the buffer plates 4 are spliced ​​to form a recess for accommodating the buffer device 2. The buffer plates 4 are provided with a slot, and the outer side of the middle part 2.2 is provided with a protrusion. The protrusion is locked inside the slot. While ensuring the support and fixation of the middle part 2.2, the buffer plates 4 can also absorb vibration.

[0033] Furthermore, a flow channel 2.9 is provided at the bottom of the suction nozzle 2.8. The suction nozzle 2.8 is connected to the horizontal plate via a flexible rotating part 2.10. The flow channel 2.9 passes through the flexible rotating part 2.10 and enters the interior of the horizontal plate, extending horizontally along the horizontal plate to the outside of the buffer device 2, and is connected to the air pump. The above structure allows for controllable suction by the air pump, enabling fixed control with the liquid bottle 1. Since it is difficult to directly squeeze out the air from the concave area of ​​the liquid bottle 1, and the concave shapes of different liquid bottles 1 are different, the suction nozzle with controllable suction and the deformability of the nozzle edge allows for adsorption with concave areas of different shapes, increasing the convenience of fixation. Additionally, the suction force of the suction nozzle 2.8 can be reduced by injecting gas to contact the suction, thereby reducing the pull-out force of the liquid bottle 1.

[0034] Furthermore, a baffle 2.11 is provided on the inner wall of the annular damping channel 2.5. A through hole 1 is provided on the baffle 2.11, and an annular groove is provided inside the baffle 2.11. An annular adjusting plate 2.12 is disposed inside the annular groove. The annular adjusting plate 2.12 is driven by a driving mechanism to slide along the annular groove, thereby realizing the rotation of the annular adjusting plate 2.12. A through hole 2 is provided on the annular adjusting plate 2.12. Through hole 1 and through hole 2 form an adjustable damping flow path. By driving the rotation of the annular adjusting plate 2.12, through hole 1 and different through holes 2 are matched, realizing the adjustment of damping performance. This allows for optimal vibration reduction by adjusting the appropriate damping performance according to different working conditions, amplitudes, and vibration frequencies.

[0035] Furthermore, through hole two includes multiple sets of different hole diameters. By rotating the annular adjusting plate 2.12 at different angles, through hole one can be matched with through hole two of different diameter sets, thereby achieving different damping and vibration reduction states.

[0036] Furthermore, a tapered transition section is provided at the end of the second through hole, realizing the transition from the size of the first through hole to the size of the second through hole, thereby making the flow of damping liquid more stable and avoiding sudden buffering oscillations.

[0037] Furthermore, a second damping mechanism is provided in the center of the damping disk. This second damping mechanism is located inside the annular damping channel 2.5 and includes an upper adjusting hole layer 2.13, a lower adjusting hole layer 2.14, and a middle elastic layer 2.15. The damping disk has a three-layer structure: the upper adjusting hole layer 2.13 at the top, the middle elastic layer 2.15 in the middle, and the lower adjusting hole layer 2.14 at the bottom. The second damping structure improves the damping characteristics and enables better damping control. The damping fluid passes through the upper and lower adjusting hole layers 2.13 and 2.14, colliding with the middle elastic layer 2.15 to further absorb vibrations.

[0038] Furthermore, the upper adjusting orifice layer 2.13 includes a rotatable upper orifice layer and a stationary upper orifice layer. The rotatable upper orifice layer is located above the stationary upper orifice layer, and the rotatable upper orifice layer and the stationary upper orifice layer are rotatably connected around a rotation center. A power mechanism drives the rotatable upper orifice layer to rotate. The rotatable upper orifice layer and the stationary upper orifice layer are provided with the same number and the same position of through holes three. By adjusting the relative rotation of the rotatable upper orifice layer and the stationary upper orifice layer, the overlap of the through holes three can be adjusted, thereby adjusting the flow area of ​​the damping fluid. By adjusting the damping area, the flow rate of the damping fluid is realized, and the damping effect is controlled.

[0039] Furthermore, the lower regulating hole layer 2.14 includes a rotatable lower hole layer and a stationary lower hole layer. The rotatable lower hole layer is located below the stationary lower hole layer, and the rotatable lower hole layer and the stationary lower hole layer are rotatably connected around a rotation center. The power mechanism two drives the rotatable lower hole layer to rotate. Both the rotatable lower hole layer and the stationary lower hole layer have the same number and the same position of through holes four. By adjusting the relative rotation of the rotatable lower hole layer and the stationary lower hole layer, the overlap of the through holes four can be adjusted, thereby adjusting the flow area of ​​the damping fluid. By adjusting the damping area, the flow rate of the damping fluid is realized, and the damping effect is controlled.

[0040] Furthermore, the intermediate elastic layer 2.15 comprises multiple annular layers with varying stiffnesses, the stiffness decreasing towards the center along the diameter. This stiffness setting enhances the damping control performance of the intermediate elastic layer 2.15, preventing it from being fully compressed onto the upper and lower adjustment hole layers 2.13 and 2.14 when the damping fluid deformation pressure is high, and also preventing poor damping and vibration reduction performance when the intermediate elastic layer 2.15 does not deform significantly under low damping fluid pressure.

[0041] Furthermore, vertical sections are provided on both the left and right sides of the connecting part 2.4, and multiple grooves are provided on the inner side of the vertical sections, with adsorption parts provided in the grooves. The adsorption parts can help support and prevent tilting, while also helping to fix the part in place.

[0042] Furthermore, the adsorption part includes a flexible hinge part, the top of which is connected to a flexible L-shaped fitting part. The length of the horizontal part of the L-shaped fitting part is greater than the length of the vertical part. This structure allows the vertical part to be hidden inside the groove, while the horizontal part, during the insertion of the liquid bottle 1, causes the L-shaped fitting part to rotate around the flexible hinge part. Ultimately, the deformation of the horizontal and vertical parts of the L-shaped fitting part achieves adsorption with the liquid bottle 1, thus providing simple auxiliary fixation.

[0043] Furthermore, multiple mass blocks are provided on the intermediate elastic layer 2.15, which can absorb vibrations while simultaneously reducing shocks, thanks to the cooperation between the elastic layer and the mass blocks.
