Description

Technical Field

[0001] The invention relates to the technical field of refrigerated fresh meat transport containers, in particular to a refrigerated fresh meat transport container with a fresh-keeping function. Background Art

[0002] Chilled meat transport boxes are special boxes used to transport chilled meat (i.e. meat that has been cooled but not frozen). The main purpose of this type of box design is to keep the meat fresh and safe during transportation and to ensure that the meat will not deteriorate due to excessively high or low temperatures.

[0003] At present, the patent with the announcement number CN219173243U discloses a meat product preservation and transportation device, which includes: a shell, one side of the shell is open, the inner top wall of the shell is fixedly connected to a limit block, the front and rear sides of the limit block are provided with a slide groove, the interior of the shell is provided with a limit rod, a card block, a slider and a placement plate, one of the slide grooves on each limit block is slidably connected to a card plate between the side wall of the shell closest to the horizontal direction, and the lower surface of the card plate is equidistantly fixedly connected with a plurality of hooks. The card plate slides between the limit block and the shell, and the lower side of the card plate is a hook for hanging meat products, thereby increasing the utilization of space, the limit rod slides in the slide groove, and the slider on the limit rod slides into the placement plate for placing meat products, thereby separating the placement plate from the ground, preventing the meat products from contacting the ground and being contaminated by bacteria, and convenient for disassembly and cleaning.

[0004] However, the above-mentioned cold fresh meat transport box still has the following problems in actual use:

[0005] When transporting larger pieces of fresh meat (such as pork, usually half a pig) in shipping boxes, the pork is often hung on hooks to ensure that the cold air inside the box can circulate evenly and avoid localized excessive temperatures caused by the stacking of meat.

[0006] However, the hooks of current transport boxes often have multiple rows and the transport boxes are deep. When the staff hang the pork on the hooks, they often need to enter the transport box and hang it from the inside to the outside. This not only increases the difficulty of operation, but also during the operation, the staff may be easily injured by hooks in other rows, posing a safety hazard. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides a cold fresh meat transport box with a fresh-keeping function to solve the problem that when transporting fresh meat through hooks inside the box body, workers are required to enter the transport box and start hanging from the inside to the outside, which not only increases the difficulty of operation, but also makes it easy for workers to be injured by hooks in other rows during operation, posing a safety hazard.

When workers hang the fresh meat, they do not need to enter the cargo box body, thereby fundamentally avoiding the risk of workers hanging the fresh meat and colliding with the hooks.

[0019] This cold fresh meat transport cargo box with a preservation function is connected to a No. 2 transmission component through a No. 1 transmission component, and then connected to a lifting component through the No. 1 transmission component and the No. 2 transmission component respectively. While the fresh meat is hung on a hook to change its position, the two lifting components can block the fresh meat in the middle from both sides of the fresh meat, which not only avoids the shaking of the pork during driving, but also can separate aisles between adjacent U-shaped hangers when there are multiple U-shaped hangers inside the cargo box body, so as to facilitate workers to walk and inspect.

[0020] This cold fresh meat transport cargo box with a preservation function has a limiting mechanism arranged at the lower ends of two lifting components. After all the fresh meat is hung, the limiting mechanism can limit the fresh meat from both sides of the lower middle end of the fresh meat at the same time, thereby further limiting the shaking of the pork inside the cargo box body; and at the same time, a support can be provided at the lower middle end of the pork to reduce the tension at the connection between the upper end of the pork and the hook, thereby reducing the probability of the pork falling off the hook during transportation.

[0021] This kind of cold fresh meat transport cargo box with a preservation function can save energy while not affecting the purpose and effect of hanging fresh meat and shielding the fresh meat after hanging, by connecting a moving component and two lifting components to a power mechanism through a first transmission component and a second transmission component.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] See also Figure 1-Figure 21 A cold fresh meat transport cargo box with a preservation function comprises a cargo box body 1 and two doors 2 installed at the opening of the cargo box body 1, a U-shaped hanger 23 is fixedly connected to the upper surface of the inner wall of the cargo box body 1, a moving opening 30 is opened inside the U-shaped hanger 23, a moving plate 24 is fixedly connected to one side of the outer wall of the U-shaped hanger 23, a sliding opening 34 connected to the moving opening 30 is opened on one side of the moving plate 24, a protective cover 3 is fixedly connected to the outer wall of the cargo box body 1 away from the door 2 and is also connected to a power mechanism, the output end of the power mechanism is connected to a No. 1 transmission assembly, the other end of the No. 1 transmission assembly is connected to a No. 2 transmission assembly, and the No. 1 transmission assembly also runs through the outer wall of the cargo box body 1 to The inside of the sliding opening 34 is respectively connected with a moving component and a lifting component, the other end of the moving component is located in the moving opening 30, and the end located in the moving opening 30 is connected with a plurality of hooks 8, the end of the No. 2 transmission component away from the No. 1 transmission component passes through the outer wall of the cargo box body 1 to the inside of the cargo box body 1 and is connected with another lifting component, the lower ends of the two lifting components are simultaneously connected with a limiting mechanism, and the upper parts of the two lifting components at one end inside the cargo box body 1 are connected to the U-shaped hanger 23, the two lifting components are respectively located on both sides of the plurality of hooks 8, the limiting mechanism is located on the outside of the plurality of hooks 8, the power mechanism, the No. 1 transmission component and the No. 2 transmission component are all located in the protective cover 3.

[0046] The cold fresh meat transport container with a preservation function in the present invention is similar to the existing cold fresh meat transport container with a preservation function, such as a meat product preservation transport device disclosed in patent publication number CN219173243U. Figures 1 to 21 As shown, when preparing to hang fresh meat (such as pork, pork is used instead below) in the cold fresh meat transport box with a fresh-keeping function of the present invention, the following steps can be followed:

[0047] First, the external transport vehicle is stopped, and then the staff opens the two doors 2 of the cargo box body 1 to both sides, so that the U-shaped hanger 23, the hook 8, etc. located inside the cargo box body 1 are exposed.

[0048] Then the staff takes all the pork that needs to be hung to the opening of the cargo box body 1, and then hangs the upper end of the first pork on the first hook 8.

[0049] After the first piece of pork is hung on the hook 8, the staff starts the power mechanism located inside the external protective cover 3 of the cargo box body 1 through the external controller.

[0050] After the power mechanism is started, the output end can control the No. 1 transmission component to rotate, and after the No. 1 transmission component rotates, it can drive the No. 2 transmission component located outside the cargo box body 1 to rotate.

[0051] When the No. 1 transmission assembly and the No. 2 transmission assembly rotate, the moving assembly and the two lifting assemblies located inside the cargo box body 1 can be moved.

[0052] After the moving assembly moves, it can be made to move horizontally in the moving opening 30 and the sliding opening 34 of the U-shaped hanger 23 and the moving plate 24 (moving from the box door 2 to the inside of the cargo box body 1).

[0053] During the movement of the moving assembly, the plurality of hooks 8 located below the moving assembly can move along with the U-shaped hanger 23 .

[0054] After the hook 8 moves, the first hook 8 on which the pork has been hung can be turned to the other side of the U-shaped hanger 23 (before this, all the hooks 8 are located on the same side of the U-shaped hanger 23), and the second hook 8 will move to the position of the original first hook 8.

[0055] Repeat steps 2-8 to hang all remaining hooks 8 with pork, and then close the door 2.

[0056] Here, the explanation continues with step 4. When the No. 1 transmission assembly and the No. 2 transmission assembly drive the moving assembly to move, the two lifting assemblies located inside the cargo box body 1 will move simultaneously.

[0057] The lifting component was originally close to or located near the top of the cargo box body 1, so as not to affect the internal space of the cargo box body 1, and after the No. 1 transmission component and the No. 2 transmission component were started.

[0058] The two lifting components will extend downward synchronously, and because the two lifting components are located on both sides of the hook 8, the hung pork will be restricted in the middle during the extension process, which can prevent the pork from shaking left and right during the driving of the vehicle, and even affect the driving safety of the vehicle due to the shaking center of gravity.

[0059] At the same time, after all the pork is hung on the hook 8, the staff starts the limiting mechanism again through the external controller.

[0060] After the limiting mechanism is activated, the output end will tighten the pork located between the two lifting components and in the middle of the limiting mechanism from both sides, thereby further limiting the shaking of the pork inside the cargo box body 1; and at the same time, a support can be made at the middle and lower ends of the pork to reduce the tension at the connection between the upper end of the pork and the hook 8, thereby reducing the probability of the pork falling off the hook 8 during transportation.

[0061] Special mention should be made here:

[0062] The number of the U-shaped hanger 23 and the power mechanism inside the cargo box body 1 is not limited to one, and can be multiple groups. The specific number is not limited. For the convenience of description and understanding, the above and below contents are all taken as an example of one group.

[0063] The external controller is a very mature technology in the prior art, so it will not be described in detail here. The external controller can be manually operated by the hanging staff, or a weight sensing sensor can be installed on the hook 8, which will automatically start when the weight is sensed. There is no specific limitation.

[0064] When the hooks 8 are replaced to hang pork, if the amount of pork is less than the number of hooks 8, the process can be stopped early after all the pork has been hung, or the remaining hooks 8 that are not hung can be moved together to the other side of the U-shaped hanger 23. In this way, the hooks 8 with the pork hung are all located inside the cargo box body 1 (i.e., away from the box door 2 and close to the front of the vehicle), which can reduce the overall center of gravity. Of course, this is only an example and is not limited to this.

[0065] The lifting components are located on both sides of the hook 8. The above and below refer to the positional relationship after the pork has been hung. Figure 5 , Figure 6 and Figure 7 As shown, when not suspended, the hook 8 is located outside the two lifting components, not between them.

[0066] As a preferred solution of the present invention, the power mechanism includes a transmission motor 4 and a motor seat 10, one end of the motor seat 10 is fixedly connected to the outer wall of the cargo box body 1, the other end of the motor seat 10 is fixedly connected to the outer wall of the transmission motor 4, the output end of the transmission motor 4 is connected to the No. 1 transmission component, and an installation opening 11 is opened through the side wall of the protective cover 3, and the outer walls of the transmission motor 4 and the motor seat 10 are slidably connected to the inner wall of the installation opening 11.

[0067] More specifically, when it is necessary to control the rotation of transmission component No. 1, it is only necessary to turn on the transmission motor 4 fixed to the outside of the cargo box body 1 by the motor base 10 through the external controller. After the transmission motor 4 is started, the output end can control the rotation of transmission component No. 1, thereby realizing the subsequent operation steps.

[0068] It should be noted that the transmission motor 4 is arranged outside the installation opening 11 in consideration of the heat dissipation of the transmission motor 4. If the transmission motor 4 has good heat dissipation effect, it can be located inside the protective cover 3. There is no specific limitation.

[0069] As a preferred solution of the present invention, the No. 1 transmission assembly includes a No. 1 rod 12, a No. 1 gear 13, a No. 2 rod 14 and a No. 2 gear 15. One end of the No. 1 rod 12 is fixedly connected to the output shaft of the transmission motor 4, and the other end of the No. 1 rod 12 passes through the No. 1 gear 13 and the cargo box body 1 to the interior of the slide 34, and is rotatably connected to the inner wall of the slide 34. At the same time, the end of the No. 1 rod 12 located in the slide 34 is also connected to the moving assembly, the outer wall of the No. 1 rod 12 is fixedly connected to the inner wall of the No. 1 gear 13, the No. 2 rod 14 passes through and is rotatably connected to the inner wall of the cargo box body 1, the No. 2 rod 14 is arranged parallel to the No. 1 rod 12, the end of the No. 2 rod 14 located inside the cargo box body 1 is connected to an end of one of the lifting assemblies away from the limiting mechanism, the end of the No. 2 rod 14 located outside the cargo box body 1 is connected to the No. 2 transmission assembly, and the outer wall of the end located outside the cargo box body 1 is also fixedly connected to the inner wall of the No. 2 gear 15, and the No. 1 gear 13 and the No. 2 gear 15 are meshed.

[0070] More specifically, when the transmission motor 4 is started, the output shaft drives the rod 12 to rotate. When the rod 12 rotates, it drives the gear 13 to rotate, and at the same time drives the moving component inside the cargo box body 1 to move. When the gear 13 rotates, it drives the gear 15 to rotate through meshing. At the same time, the gear 15 drives the rod 14 in the middle to rotate. Then the rod 14 drives the transmission component No. 2 and one of the lifting components inside the cargo box body 1 to move.

[0071] It should be noted here that in order to ensure the number of hooks 8 and ensure that adjacent hooks 8 will not hinder each other after the pork is hung, the length of the moving component is relatively long, for example, a distance of nearly half of the internal length of the cargo box body 1, and the lifting component only needs to be lowered a certain distance so that the lower end of the lifting component is located at the middle and lower end of the hanging pork. The pork usually leaves a certain distance from the bottom surface of the cargo box body 1 after hanging, so the lifting component usually only drops about half of the height of the cargo box body 1. Therefore, in order to ensure that the moving component and the lifting component can move at the same time and will not affect the normal transmission of the power mechanism during the movement, the number of teeth of the first gear 13 and the second gear 15 can be set differently, so that the number of teeth of the second gear 15 is more, so that after the moving component hangs the pork on the last hook 8 and moves, the lifting component can also be moved to the specified position.

[0072] As a preferred solution of the present invention, the No. 2 transmission assembly includes a No. 1 sprocket 16, a No. 1 chain 17, a No. 3 rod 18 and a No. 2 sprocket 19. The No. 1 sprocket 16 is sleeved on and fixedly connected to the outer wall of the No. 2 rod 14 at one end outside the cargo box body 1. The No. 3 rod 18 penetrates and is rotatably connected to the inner wall of the cargo box body 1. The No. 3 rod 18 is arranged parallel to the No. 2 rod 14. The end of the No. 3 rod 18 located inside the cargo box body 1 is connected to an end of another lifting assembly away from the limiting mechanism. The outer wall of the No. 3 rod 18 located at one end outside the cargo box body 1 is fixedly connected to the inner wall of the No. 2 sprocket 19. The No. 1 chain 17 is sleeved on the outside of the No. 1 sprocket 16 and the No. 2 sprocket 19, and the No. 1 chain 17 is meshed with both the No. 1 sprocket 16 and the No. 2 sprocket 19.

[0073] More specifically, when the No. 2 gear 15 rotates with the No. 2 rod 14, the No. 2 rod 14 can rotate with the No. 1 sprocket 16, and then the No. 1 sprocket 16 can rotate synchronously with the No. 2 sprocket 19 through the No. 1 chain 17 around the No. 3 rod 18 at the same speed, and when the No. 3 rod 18 rotates, it can move with another lifting component located inside the cargo box body 1.

[0074] It should be particularly noted here that the first sprocket 16 and the second sprocket 19 have the same size, so that the movement direction and speed of the two lifting assemblies can be the same.

[0075] As a preferred solution of the present invention, the lifting assembly includes a baffle 6, a hanging plate 25, two connecting plates 21, two moving blocks 36 and four supporting blocks 20, one side of the outer wall of the hanging plate 25 is fixedly connected to the side wall of the U-shaped hanger 23, the hanging plate 25 and the baffle 6 are arranged in parallel up and down, wherein the two supporting blocks 20 are respectively fixedly connected to the ends of the hanging plate 25 and the baffle 6 away from the box door 2, and the other two supporting blocks 20 are respectively fixedly connected to the two moving blocks 36, an upper slide groove 29 is provided on the bottom surface of the hanging plate 25 close to the box door 2, a lower slide groove 9 is provided on the upper surface of the baffle 6 close to the box door 2, the two moving blocks 36 are respectively located in the upper slide groove 29 and the lower slide groove 9, and ... The outer walls of the block 36 are slidably connected to the inner walls of the upper slide groove 29 and the lower slide groove 9 respectively, the two connecting plates 21 are cross-arranged, and the intersection is rotatably connected through a rotating shaft, the two ends of the two connecting plates 21 are rotatably connected to the four support blocks 20 respectively through a rotating shaft, the outer walls of the No. 2 rod 14 and the No. 3 rod 18 located at one end inside the cargo box body 1 are rotatably connected to the inner walls of the upper slide grooves 29 of the two hanging plates 25 respectively, the two moving blocks 36 located in the upper slide grooves 29 of the two hanging plates 25 are respectively sleeved and threadedly connected to the outer walls of the No. 2 rod 14 and the No. 3 rod 18, the bottom surfaces of the outer walls of the two baffles 6 are respectively connected to the two ends of the limiting mechanism, and the two baffles 6 and the two hanging plates 25 are respectively located on both sides of a number of hooks 8.

[0076] More specifically, when the No. 2 rod 14 and the No. 3 rod 18 rotate, the two moving blocks 36 can be moved in the two upper grooves 29 of the two hanging plates 25 respectively. Because the two connecting plates 21 between the hanging plate 25 and the baffle 6 are cross-arranged, and one end of the two connecting plates 21 is limited to one end of the hanging plate 25 and the baffle 6, it can only rotate but not slide. Therefore, as the moving block 36 moves in the upper groove 29, the angle between the upper and lower parts of the two connecting plates 21 will be passively reduced, thereby gradually pushing the baffle 6 downward, and then the height change between the hanging plate 25 and the baffle 6 can be achieved; and when the two baffles 6 descend, the limiting components at the lower ends of the two baffles 6 can also be pushed down together, thereby achieving the subsequent limiting of the pork.

[0077] It should be particularly noted here that: due to the limitation of the connecting plate 21 , when one of the moving blocks 36 moves in the upper slide groove 29 , the moving block 36 located in the lower slide groove 9 of the baffle plate 6 will also move along the lower slide groove 9 .

[0078] As a preferred solution of the present invention, the limiting mechanism includes a U-shaped plate 5, a driving assembly and a plurality of telescopic assemblies. The upper surface of the outer wall of the U-shaped plate 5 is fixedly connected to the bottom surfaces of the two baffles 6, and the U-shaped plate 5 is located outside the plurality of hooks 8. One end of the driving assembly is located outside the U-shaped plate 5. The output end of the driving assembly passes through the outer wall of the U-shaped plate 5 to the inside of the U-shaped plate 5 and is connected to the plurality of telescopic assemblies. The plurality of telescopic assemblies are divided into two groups, which are respectively located on both sides of the inside of the U-shaped plate 5 and on both sides of the plurality of hooks 8.

[0079] More specifically, when it is necessary to limit the position of the pork between the two vertical rods of the U-shaped plate 5 (i.e., between the two baffles 6), it is only necessary to turn on the driving component through an external controller. After the driving component is started, a number of telescopic components can be controlled to extend outward through the output end, so that the pork in the middle can be clamped from both sides, thereby reducing the probability of the pork shaking and falling off.

[0080] As a preferred embodiment of the present invention, the driving assembly includes a puncture motor 7, a No. 3 chain 43, two No. 4 rods 28 and two No. 3 sprockets 42. The outer wall of the puncture motor 7 is fixedly connected to the outer wall of the U-shaped plate 5. The two No. 4 rods 28 are respectively located on both sides of the U-shaped plate 5, and the outer walls of the two No. 4 rods 28 are rotatably connected to the inner wall of the end of the U-shaped plate 5. The output shaft of the puncture motor 7 is fixedly connected to one end of one of the No. 4 rods 28. The two No. 3 sprockets 42 are respectively sleeved and fixedly connected to the outer walls of the two No. 4 rods 28. The No. 3 chain 43 is sleeved on the outside of the two No. 3 sprockets 42, and the No. 3 chain 43 is meshed with the two No. 3 sprockets 42. The ends of the two No. 4 rods 28 located inside the U-shaped plate 5 are respectively connected to a number of telescopic assemblies.

[0081] More specifically, when limiting is required, the external controller starts the puncture motor 7, and the output shaft of the puncture motor 7 drives one of the No. 4 rods 28 to rotate. After the No. 4 rod 28 rotates, it can drive one of the No. 3 sprockets 42 connected to the surface to rotate together, and then drive another No. 3 sprocket 42 and another No. 4 rod 28 to rotate through the No. 3 chain 43, thereby simultaneously driving several telescopic components located between the two vertical rods of the U-shaped plate 5 to move.

[0082] As a preferred embodiment of the present invention, the telescopic assembly includes a puncture cone head 27, a threaded rod 37, a worm wheel 38, an anti-slip ring 39, a worm 41 and a rectangular strip 44.

A plurality of puncture openings 26 are provided through one side adjacent to the two vertical rods of the U-shaped plate 5, and the plurality of puncture openings 26 are respectively located in the plurality of anti-slip openings 40. One end of the rectangular strip 44 is fixedly connected to the inner wall of the U-shaped plate 5, and the other end of the U-shaped plate 5 is located in the threaded rod 37. The outer wall of the U-shaped plate 5 is slidably connected to the inner wall of the threaded rod 37, the other end of the threaded rod 37 passes through the worm gear 38 and the puncture port 26 and is fixedly connected to the puncture cone head 27, the outer wall of the threaded rod 37 is threadedly connected to the inner wall of the worm gear 38, the outer wall of the threaded rod 37 is slidably connected to the inner wall of the puncture port 26, the side of the worm gear 38 close to the puncture cone head 27 is fixedly connected to one end of the anti-slip ring 39, the other end of the anti-slip ring 39 is located in the anti-slip port 40, and the outer wall of the anti-slip ring 39 is rotatably connected to the inner wall of the anti-slip port 40, and the worm gear 38 and the worm 41 are meshed.

[0083] More specifically, when the No. 4 rod 28 rotates, it can rotate with the worm 41 connected to the surface, and the worm wheel 38 will rotate along with the worm 41 due to the restrictions of the anti-slip ring 39 and the anti-slip opening 40. When the worm wheel 38 rotates, the threaded rod 37 located inside the worm wheel 38 cannot rotate due to the restriction of the rectangular bar 44, and will slide out toward the puncture opening 26 due to the threaded manner, so that the puncture cone head 27 can be gradually inserted into the pork hanging on the hook 8.

[0084] As a preferred embodiment of the present invention, the moving assembly includes a third gear 22, an active slider 32, a second chain 33, a driven slider 35 and a plurality of I-shaped blocks 31, the outer wall of the active slider 32 is slidably connected to the inner wall of the sliding opening 34 and the moving opening 30, and one end of the active slider 32 is sleeved and threadedly connected to the outer wall of the first rod 12, the other end of the active slider 32 is fixedly connected to one end of the second chain 33, and the other end of the second chain 33 is fixedly connected to one end of the driven slider 35, and the outer wall of the second chain 33 and the driven slider 35 are connected to the outer wall of the second chain 33 and the driven slider 35. The walls are slidably connected to the inner wall of the movable opening 30, the upper end of the third gear 22 is rotatably connected to the upper end of the inner wall of the cargo box body 1 through a rotating shaft, the No. 2 chain 33 is meshed with the No. 3 gear 22, the bottom surface of the No. 2 chain 33 is fixedly connected to the upper ends of a plurality of I-shaped blocks 31, the lower ends of a plurality of I-shaped blocks 31 pass through the bottom surface of the U-shaped hanger 23 to the bottom of the U-shaped hanger 23, and are respectively fixedly connected to the upper ends of a plurality of hooks 8, and rollers are provided at the connection between the active slider 32, the driven slider 35 and a plurality of I-shaped blocks 31 and the sliding opening 34 and the movable opening 30.

[0085] More specifically, when the No. 1 rod 12 rotates, the active slider 32 located in the sliding mouth 34 can be moved by the thread. Since the other end of the active slider 32 is located in the moving mouth 30, the No. 2 chain 33 located in the moving mouth 30 and the driven slider 35 located at the other end of the No. 2 chain 33 can be pulled together to move. When the No. 2 chain 33 moves, several hooks 8 located under the No. 2 chain 33 can be displaced together, thereby realizing the position change of the hooks 8.

[0086] It should be noted that rollers are provided at the connection between the active slider 32 , the driven slider 35 , and the I-shaped blocks 31 and the sliding opening 34 and the moving opening 30 , so as to reduce friction during movement and reduce wear.
