Description

Technical Field

[0001] This utility model belongs to the field of fresh food cold chain distribution technology, and in particular relates to a fresh food cold chain turnover and distribution device with airbag shock absorption. Background Technology

[0002] Fresh food cold chain distribution refers to the logistics process of transporting perishable fresh products through multiple nodes using low-temperature control technology. Its core lies in maintaining a constant low-temperature environment through professional refrigeration equipment to ensure the quality stability of goods during loading, unloading, temporary storage, and transshipment. This model covers the entire chain from production to end, and reduces the risk of loss caused by temperature fluctuations through standardized operations.

[0003] A Chinese patent application with publication number CN223174584U discloses a cold chain distribution device for fresh produce, including a cold chain box, an inner liner, a lid, and a sealing ring. The inner liner is fixedly installed on the bottom of the inner wall of the cold chain box, the lid is movably connected to both sides of the top rear side of the cold chain box, and the sealing ring is fixedly connected to the surface of the lid. A cleaning groove is provided at the bottom of the inner liner surface, with four sets of cleaning grooves. This invention, by setting up cleaning grooves, a collection bin, and cleaning components, can effectively clean the bottom of the inner wall of the inner liner, allowing residual moisture and impurities to be discharged through the cleaning grooves. This solves the problem that when storing fresh produce, moisture and impurities on the surface of the fresh produce fall into the interior of the inner liner. Because no auxiliary cleaning structure is provided, it is difficult to clean the residual moisture and impurities inside the inner liner, leading to the growth of bacteria and mold, and the impurities and moisture affecting the quality of the fresh produce.

[0004] Although the patented cleaning component can clean the inner liner and prevent residual moisture and impurities from affecting the quality of fresh produce, it lacks protective functions. During delivery and transportation, it mainly relies on its rigid structure and limited cushioning materials to absorb impacts from road bumps. Due to the lack of cushioning protection, the fresh produce stored inside is easily damaged, affecting its quality and normal sales, making it unsuitable for use.

[0005] To address these issues, we provide a fresh food cold chain turnover and distribution device with airbag shock absorption. Utility Model Content

[0011] The present invention is further configured such that through holes are provided on both sides of the fixed shell for use with the screw, and the bottom of the threaded sleeve is fixedly connected to the inner wall of the fixed shell through the mounting seat. The through holes facilitate the use position of the screw adjusting the top block, and the mounting seat is used to increase the stability of the installation and fixation between the threaded sleeve and the fixed shell.

[0012] The present invention is further configured such that the reset mechanism includes a sliding sleeve, the front and rear sides of which are fixedly connected to the inner wall of the buffer shell, a sliding rod is slidably connected to the inner wall of the sliding sleeve, a spring is sleeved on the surface of the sliding rod, and the opposite sides of the two sliding rods are fixedly connected to the piston plate.

[0027] Example 1

[0028] Please see Figure 1-6 This utility model is a fresh food cold chain turnover and distribution device with airbag shock absorption, including a shell 1 and an airbag protection assembly 4. A sealing cover 2 is movably connected to the top of the rear side of the shell 1, and a sealing mechanism 3 is provided on the top of the front side of the shell 1. The airbag protection assembly 4 includes a buffer shell 41. The bottom of the buffer shell 41 is fixedly connected to the inner wall of the shell 1. A reset mechanism 42 is provided on both sides of the inner cavity of the buffer shell 41. A piston plate 43 is provided on the opposite side of the two reset mechanisms 42. A slope block 44 is fixedly connected on the opposite side of the two piston plates 43. A pressure block 45 is provided between the two slope blocks 44. The top of the pressure block 45 penetrates the buffer shell 41 and is fixedly connected to an inner liner 46.

Both sides of the buffer shell 41 are connected to the annular airbag 48.

[0029] Specifically: the sealing mechanism 3 can tightly fit the sealing cover 2 downwards with the housing 1, and squeeze the sealing ring to improve the sealing effect; the reset mechanism 42 can control the piston plate 43 to reset when the slope block 44 is not squeezed; the pressure block 45 can transmit the bumps to the slope block 44; when the slope block 44 is compressed, it can control the displacement of the piston plate 43; when the piston plate 43 moves inside the buffer shell 41, it will deliver gas to the annular airbag 48 and the elastic airbag 47. The annular airbag 48 and the elastic airbag 47 buffer and protect the inner liner 46 and the fresh products stored inside it, so as to avoid the fresh products from being affected by the bumps and affecting the quality and normal sales.

[0030] Example 2

[0031] Please see Figure 1-6 Based on Embodiment 1, the sealing mechanism 3 includes a fixed shell 31, the rear side of which is fixedly connected to the shell 1. A threaded sleeve 32 is fixedly connected to the bottom of the inner cavity of the fixed shell 31. Both sides of the inner cavity of the threaded sleeve 32 are threadedly connected to screws 33. The opposite sides of the two screws 33 penetrate the fixed shell 31 and are movably connected to a top block 34. Adjusting blocks 35 are fixedly connected to both sides of the front side of the sealing cover 2. A rotating sleeve is fixedly connected to the surface of the screws 33. The opposite sides of the two screws 33 are movably connected to the top block 34 through bearings. The rear side of the adjusting block 35 is fixedly connected to the sealing cover 2 by bolts. Both sides of the fixed shell 31 have openings for connecting the screws. The threaded sleeve 32 is fixedly connected to the inner wall of the fixed shell 31 via a mounting base. The reset mechanism 42 includes a sliding sleeve 421. The front and rear sides of the sliding sleeve 421 are fixedly connected to the inner wall of the buffer shell 41. A sliding rod 422 is slidably connected to the inner wall of the sliding sleeve 421. A spring 423 is sleeved on the surface of the sliding rod 422. The opposite sides of the two sliding rods 422 are fixedly connected to the piston plate 43. A support plate is fixedly connected to the top of the pressure block 45. The top of the buffer shell 41 has an open opening that works with the pressure block 45. The rear side of the sealing cover 2 is movably connected to the shell 1 via a hinge. A sealing ring is fixedly connected to the bottom of the sealing cover 2.

[0032] Specifically: the fixed housing 31 facilitates the installation and fixation of the threaded sleeve 32; the threaded sleeve 32 cooperates with the screw 33 to control the position of the top block 34; the top block 34 can press against the inclined surface of the adjusting block 35, allowing the sealing cover 2 to press down on the housing 1 and the sealing ring, improving the sealing effect of the housing 1; the rotating sleeve allows the user to easily rotate the screw 33; the bearing ensures that the rotation of the screw 33 does not affect the pressing of the top block 34 against the adjusting block 35; the bolt-fixed adjusting block 35 facilitates user disassembly and replacement; and the through hole allows the screw 33 to easily adjust the top block 34. The mounting base is used to increase the stability of the installation and fixation between the threaded sleeve 32 and the fixed shell 31. The sliding sleeve 421 and the sliding rod 422 can limit the piston plate 43 so that it can be smoothly adjusted to the left and right positions. The spring 423 can control the piston plate 43 to return to its original position when the slope block 44 is not compressed. The support plate can increase the fixing area between the pressure block 45 and the inner liner 46. The movable opening facilitates the pressure block 45 to compress the slope block 44. The hinge facilitates the opening or closing of the sealing cover 2. The sealing ring can improve the sealing effect between the sealing cover 2 and the shell 1.

[0033] The working principle of this utility model is as follows: During the delivery and transportation process, when the shell 1 is subjected to bumps and impacts, the inner liner 46 drives the pressure block 45 to move downwards. The pressure block 45 contacts the inclined surfaces of the two side slope blocks 44, converting the vertical impact force into a horizontal component force, which pushes the two piston plates 43 to move horizontally. The piston plates 43 move within the buffer shell 41 and compress the cavity gas. The compressed gas enters the annular airbag 48 and the elastic airbag 47 through the conduit respectively. The annular airbag 48 expands uniformly around the inner liner 46 to form a ring-shaped buffer layer. The elastic airbag 47 inflates and expands in the gap between the inner wall of the shell 1 and the inner liner 46, absorbing and dispersing the impact energy. After the impact weakens, the spring 423 pushes the slide rod 422 and the piston plate 43 to reset, and the gas flows back to the buffer. The casing 41 facilitates the next buffering operation, providing cushioning protection for fresh produce and preventing damage from rigid collisions. This also prevents transportation bumps from affecting the quality of the fresh produce. When sealing the casing 1 is required, the rotating sleeve on the surface of the screw 33 is rotated. The rotating sleeve controls the rotation of the screw 33, causing it to move in conjunction with the threaded sleeve 32. At the same time, the screw 33 pushes the top block 34 against the inclined surface of the adjusting block 35. The inclined surface converts the horizontal thrust into a vertical downward pressure, forcing the sealing cover 2 down and squeezing the sealing ring at the bottom. This causes the sealing ring to deform and fill the gap between the sealing cover 2 and the casing 1, increasing the sealing effect between the casing 1 and the sealing cover 2 and preventing the fresh produce from being affected by the external environment during the turnover and distribution process.
