Reasonable packaging can not only protect goods from damage, but also enhance the brand image and enhance consumers' shopping experience.

[0003] There are already packaging boxes of various materials and designs on the market, but there are still many shortcomings in actual use. For example, traditional hard solid boxes are not specially designed for bottled and canned goods. The usual practice is to fill a large amount of bubble film or other soft fillers in the packaging box in order to achieve a shock-absorbing effect. However, this method has obvious limitations. First of all, although a large amount of fillers can provide cushioning to a certain extent, due to the lack of targeted design, it is impossible to ensure that each bottle and can can be evenly and effectively fixed. Especially in the case of mixed packaging of multiple items, collisions between the items are still difficult to avoid, resulting in insufficient stability of the packaging box and inability to provide adequate protection. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-5The present invention provides a technical solution: a cargo packaging box, comprising a box body 1, an inner lining board 2 is installed at the bottom end of the box body 1, a plurality of limiting bases 3 are evenly arranged on the top of the inner lining board 2, and elastically retractable extrusion clamps 4 are symmetrically arranged inside the limiting base 3, the limiting base 3 is a circular seat structure as a whole, and the extrusion clamps 4 are symmetrically distributed inside the limiting base 3, the extrusion clamps 4 are arc-shaped structures and a plurality of protrusions are arranged on the inner wall, and the limiting bases 3 are connected and fixed to the inner lining board 2 through a rotating positioning mechanism 5, and vertical shafts 6 are inserted on both sides of the top of the limiting base 3, and a height-adjustable reinforcement limiting mechanism 7 is arranged on the vertical shaft 6, and the reinforcement limiting mechanism 7 is composed of an outer clamp 71, an inner clamp 72 and a connecting sleeve 73, and the connecting sleeve 73 It is fixed on the outside of the outer clamping block 71 and sleeved on the outside of the vertical shaft 6. The connecting sleeve 73 is connected with a locking bolt through a threaded structure. The inner clamping block 72 is arranged on the inner side of the outer clamping block 71. When it is necessary to put fragile items such as bottles into the box body 1, the operator can adjust the limiting base 3 to a suitable position by rotating the positioning mechanism 5, so that the limiting base 3 can correspond to the position where the bottles are placed, and the squeezing clamping block 4 inside the limiting base 3 is in a natural state, providing sufficient space for the placement of the bottles. When the bottles are gently placed on the limiting base 3, the squeezing clamping block 4 will automatically shrink inwards due to its elastic characteristics, tightly wrapping the bottom end of the bottles, thereby achieving preliminary fixation. At the same time, in order to further enhance the fixing effect, the reinforcing limiting mechanism on the vertical shaft 6 can be adjusted 7, that is, the positions of the outer clamp block 71 and the inner clamp block 72 are adjusted according to the height of the bottle, so that the inner clamp block 72 fits tightly against the upper part of the bottle, and at the same time, the locking bolt on the connecting sleeve 73 is used to lock it, so as to ensure that the outer clamp block 71 and the inner clamp block 72 firmly fix the bottle to prevent it from shaking or displacement during transportation. In this process, the elastic connection between the inner clamp block 72 and the outer clamp block 71 can adapt to bottles of different diameters, thereby enhancing the application range of the device, thereby not only improving the stability of the bottles and other items in the box body 1, but also significantly reducing the risk of damage caused by collision during transportation, solving the problem that the filler cannot provide effective fixation in the traditional packaging method, and greatly improving the safety and reliability of the packaging. The rotating positioning mechanism 5 is composed of a rotating seat 51 and a positioning block 52 The positioning block 52 is fixed on the top of the inner bottom substrate 2, the rotating seat 51 is rotatably connected to the outside of the positioning block 52 through a rotating shaft, and the bottom of the limiting base 3 is welded and fixed to the top of the rotating seat 51. The rotating seat 51 of this structural rotation and positioning mechanism 5 can be rotated outside the positioning block 52 through a rotating shaft to quickly adjust the position of the limiting base 3 to adapt to the appropriate position orientation when the bottle is placed, ensuring that each bottle can be accurately placed on the limiting base 3. An annular damping ring 53 is provided on the top of the positioning block 52, and an annular groove seat 54 that matches the annular damping ring 53 structure is provided on the top inner wall of the rotating seat 51. When the rotating seat 51 rotates on the positioning block 52, the contact between the annular damping ring 53 and the annular groove seat 54 will generate a certain resistance.This resistance can not only ensure that the rotating seat 51 and the limiting base 3 fixed thereon can be adjusted to the desired position steadily and smoothly, but also provide appropriate fixing force after being adjusted into place to prevent the limiting base 3 from accidentally moving due to external vibration or impact. The inner substrate 2 is made of a thin metal material as a whole. A circular magnetic sheet 55 is embedded in the center of the bottom of the positioning block 52. The outer edge of the circular magnetic sheet 55 is provided with an annular magnetic sheet 56, and the top of the inner substrate 2 is provided with a plurality of groups of adsorption ports that match the structures of the circular magnetic sheet 55 and the annular magnetic sheet 56. When the limiting base 3 needs to be adjusted or installed, the operator can quickly place the positioning block 52 on any adsorption port of the inner substrate 2 by rotating the positioning mechanism 5. The circular magnetic sheet 55 and the annular magnetic sheet 56 will The suction port on the inner bottom substrate 2 generates a strong magnetic attraction, which quickly fixes the position of the positioning block 52 and ensures that the limiting base 3 is stable and immovable. At the same time, this magnetic connection design also allows each limiting base 3 unit to be quickly disassembled. The positioning block 52 can be easily removed by simply overcoming the magnetic force, which is convenient for reconfiguration or cleaning and maintenance, thereby improving the flexibility of the internal layout of the box body 1 and the convenience of operation. Active blocks 31 are provided on the outside of both sides of the limiting base 3, and pressure shafts 32 are provided at the upper and lower ends of the inner side of the active block 31. The outer ends of the pressure shafts 32 are movable and penetrate the limiting base 3 and are fixedly connected to the outer connection of the extrusion clamp 4. Notches are provided on the inner walls on both sides of the limiting base 3, and elastic telescopic blocks 33 are provided on the notches on the inner walls on both sides of the limiting base 3. The shrinking block 33 is made of elastic rubber material. With this structure, when the bottle is placed in the limiting base 3, the bottom of the bottle will first contact the squeezing clamping block 4. As the bottle continues to be placed downward, the squeezing clamping block 4 will shrink inward under pressure, driving the pressing shaft 32 to slide along the limiting base 3. At the same time, the elastic expansion block 33 located in the recesses on the inner walls of both sides of the limiting base 3 will be compressed to generate an elastic reaction force, which is transmitted to the pressing shaft 32 through the limiting base 3, thereby allowing the squeezing clamping block 4 to maintain a continuous clamping force on the bottle. When the bottle is fully placed in place, the squeezing clamping block 4 will tightly wrap the bottom of the bottle under the elastic force provided by the elastic expansion block 33 to ensure that the bottle is stable and does not shake. This not only allows each bottle to be evenly and firmly fixed, but also can adapt to In order to adapt to bottles and cans of different diameters, the versatility and flexibility of the box body 1 are improved. Horizontal shafts 34 are welded and fixed to the outside of both sides of the limiting base 3, and the bottom end of the movable block 31 is movably sleeved on the outside of the horizontal shaft 34, and the outer sleeve of the outer end of the horizontal shaft 34 is provided with a spring member 35, and the two ends of the spring member 35 are respectively connected to the inner side of the outer end of the horizontal shaft 34 and the outer side of the bottom end of the movable block 31. When the movable block 31 of this structure is forced to move outward, it will synchronously slide along the outside of the horizontal shaft 34 and compress the spring member 35. When the bottle can is fully placed in place, the spring member 35 releases the stored elastic energy and synchronously pushes the movable block 31 back to its original position through the horizontal shaft 34, so that the extrusion clamping block 4 further improves the continuous clamping force on the bottle can, so that the stabilizing effect will be better.The four corners of the bottom end of the inner wall of the box body 1 are welded and fixed with support blocks, and a gap of 3-5 cm in height is reserved between the inner lining board 2 and the bottom inner wall of the box body 1. In this structure, the four corners of the inner lining board 2 can be snapped on the support blocks at the four corners of the inner wall of the box body 1, thereby forming an air layer between the inner lining board 2 and the bottom inner wall of the box body 1. The air layer helps air circulation and avoids the accumulation of water vapor at the bottom of the inner lining board 2 in a humid environment, which has a certain moisture-proof effect on the inside of the box body 1. The outer clamp block 71 and the inner clamp block 72 are both arc-shaped deformable elastic metal materials. The outer clamp block 71 and the inner clamp block 72 are connected by an elastic support pad 74. The elastic support pad 74 is made of a sponge material with good elasticity. The elastic metal material of the outer clamp block 71 and the inner clamp block 72 of this structure enables fine adjustment according to the diameter of the bottle to ensure uniform distribution of the clamping force and avoid damage to the surface of the bottle due to excessive local pressure. At the same time, the elastic support pad 74 not only increases the buffering effect between the outer clamp block 71 and the inner clamp block 72, but also absorbs part of the energy when the bottle is subjected to external impact, reducing the impact force transmitted to the bottle.

[0020] Working principle: When using the cargo packaging box, first install the inner bottom plate 2 at the bottom end of the box body 1, that is, the four corners of the inner bottom plate 2 are engaged with the support blocks at the four corners of the inner wall of the box body 1. Then, according to the number and layout of bottles and cans to be placed, the positioning block 52 of the rotating positioning mechanism 5 is magnetically adsorbed to the adsorption port on the inner bottom plate 2 through the circular magnetic attraction piece 55 and the annular magnetic attraction piece 56, so as to quickly fix the appropriate number of limit bases 3. , then the rotating seat 51 rotates outside the positioning block 52 through the rotating shaft to adjust the limiting base 3 to a suitable position. When the rotating seat 51 rotates, the annular groove seat 54 is driven to contact the annular damping ring 53 to generate resistance. After adjustment, the bottle is gently placed on the limiting base 3. The extrusion clamping block 4 inside the limiting base 3 will automatically shrink inward due to its elastic characteristics. The movement of the extrusion clamping block 4 drives the pressing shaft 32 to slide along the limiting base 3, and drives the movable block 31 to move outward. The movable block 31 is subjected to force and will synchronously slide along the outside of the horizontal axis 34 and compress the spring member 35. When the bottle is completely placed in place, the spring member 35 releases the stored elastic energy and pushes the movable block 31 back to its original position through the horizontal axis 34, so that the extrusion clamping block 4 further increases the continuous clamping force on the bottle to tightly wrap the bottom of the bottle. In order to further enhance the fixing effect, the reinforcing limiting mechanism 7 on the vertical axis 6 can be adjusted, that is, the positions of the outer clamping block 71 and the inner clamping block 72 can be adjusted according to the height of the bottle, so that the inner clamping block 72 fits tightly against the upper part of the bottle to further prevent it from shaking or shifting during transportation. Through the above steps, the fixation of the bottle in the cargo box 1 is completed, thereby ensuring the stability and safety of the bottle during transportation, thereby completing a series of tasks.
