DETAILED DESCRIPTION

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] like Figure 1-Figure 8As shown, a smart cold chain storage device with a classification effect of the present invention comprises a storage bin 1, wherein a shelf plate 2 is installed inside the storage bin 1, the shelf plate 2 is hollow in design and has three support plates 21 fixed on each side, two slide grooves on the top of the support plate 21 are slidably connected with a protrusion 32 fixed on the bottom of the loading box 3, the loading box 3 is provided with three places, and a cargo box 31 is placed on the top of the loading box 3, three arc panels 23 which are not in the same plane are fixed on the inner side of the vertical plate 22 welded on one side of the shelf plate 2, the support plate 21 and the loading box 3 are connected with a driving part 4 for driving the protrusion 32 to slide in the slideway, a clamping part 5, the clamping part 5 is installed on the loading box 3, and includes a flat plate 51 sliding in a side hole of the loading box 3, a pulley 52 is installed on one side of the flat plate 51, and the pulley 52 can contact the arc surface of the arc panel 23 when the protrusion 32 slides, and one side of the L-shaped clamping plate 53 is fixed to the other end of the flat plate 51, and this side of the L-shaped clamping plate 53 is connected to the loading box 3 with a spring 54, and the L-shaped clamping plate 53 One side of the inner side is in contact with the cargo box 31, and the other side is provided with three air bags 55 for clamping. An inflating part 56 for inflating the air bags 55 is installed on one side of the L-shaped clamping plate 53. The L-shaped clamping plate 53 slides in the slideway inside the loading box 3. The three flat plates 51 correspond to the three curved panels 23 in one-to-one position. A positioning part 6 is installed in the inner cavity of the shelf plate 2. The positioning part 6 is used to limit the position of the loading box 3. The positioning part 6 is connected to the driving part 2 7 installed in the inner cavity of the shelf plate 2. The driving part 2 7 Used to release the position limitation of the positioning part 6 on the loading box 3, the inflation part 56 includes three piston rods 561, one end of the piston rod 561 seals and slides in the airway inside the L-shaped clamp 53, and the airway is provided with an air hole connected to the inside of the airbag 55, the outer end of the piston rod 561 is commonly fixed with a push plate 562, the push plate 562 and the L-shaped clamp 53 are connected with a spring 563 sleeved on the outside of the piston rod 561, the push plate 562 can be moved through the L-shaped clamp 53 to fit the inner wall of the loading box 3.

[0025] As described above, by installing the loading box 3, the cargo box 31, and the clamping part 5, in terms of design, the three arc panels 23 on the vertical plate 22 are successively higher from the outside to the inside (referring to the direction from the opening of the storage bin 1 to the inside), then the first loading box 3 is placed in the support plate 21, and the protrusion 32 is inserted into the top slide groove of the support plate 21 to form a sliding connection, then the cargo box 31 containing refrigerated goods is placed in the loading box 3, and is fitted with the adjacent surfaces of the two inner corners, and then the loading box 3 is driven to move into the storage bin 1 by the driving part 14, and the position of the flat plate 51 on the loading box 3 is aligned with the innermost arc panel 23 is the same height, so it will not contact the two front curved panels 23. When the pulley 52 of the flat plate 51 contacts the inclined curved surface of the curved panel 23, the pulley 52 rolls on the curved surface until it rolls to the horizontal surface of the curved panel 23 and stops. At this time, the loading box 3 is automatically positioned by the positioning part 6. In this process, the flat plate 51 is pushed, and then the L-shaped clamping plate 53 is pushed to slide. Finally, one side of the L-shaped clamping plate 53 is in contact with the outer wall of the cargo box 31, and the other side of the L-shaped clamping plate 53 also moves, so that the push plate 562 in the inflatable part 56 is in contact with the inner wall of the loading box 3. At this time, the push plate 562 The L-shaped clamping plate 53 is unable to move and continues to move, so that the piston rod 561 moves into the airway, so that the gas in the airway is introduced into the airbag 55, and finally the airbag 55 expands and contacts the cargo box 31. Finally, the four sides of the cargo box 31 are tightly attached to the two sides inside the loading box 3, one side of the L-shaped clamping plate 53 and the airbag 55 to complete the fixation. When the cargo box 31 moves out and the pulley 52 loses contact with the curved panel 23, the spring 2 563 and the spring 1 54 can drive the L-shaped clamping plate 53 and the piston rod 561 to reset and release the clamping, and then the next two loading boxes 3 are put in order, and the same steps are followed. In the first step, the cargo box 31 is clamped by squeezing the corresponding flat plates 51 on the middle and outermost loading boxes 3 through the second arc panel 23 in the middle and the outermost arc panel 23 at the bottom, and then the three cargo boxes 31 on a support plate 21 are placed. Different types of items are placed in the three cargo boxes 31, which not only completes the classified placement, but also effectively fixes the cargo boxes 31 to avoid damage to the items caused by shaking during transportation, and the fixation can be automatically released by the spring second 563 and the spring one 54. The design is very clever and does not require the design of a manual clamping mechanism, thereby improving the efficiency of placement and taking.

[0026] Three “L”-shaped curved rods 57 are fixed on the top of the L-shaped clamping plate 53 , and the curved rods 57 can be inserted into the rod holes on one side of the box cover of the cargo box 31 .

[0027] As mentioned above, after clamping is completed, the cargo box 31 can be fixed in the up and down directions by the curved rod 57 to prevent it from bouncing up due to vibration during transportation, and the clamping can also be automatically released, which is very convenient. It should be noted that the lid of the cargo box 31 is designed to be locked.

[0028] The driving unit 1 4 includes a motor 41 fixed to the front of the loading box 3 , a driving gear 42 is fixed to the bottom of the motor 41 , and the driving gear 42 is meshed with a tooth path 43 on the inner side of the groove at the top of the support plate 21 .

[0029] As described above, by designing the driving part 4, after the loading box 3 is placed on the top of the support plate 21, it is gently pushed so that the driving gear 42 contacts the first tooth block of the tooth track 43. At this time, the motor 41 is started to rotate the driving gear 42 to form an engagement with the tooth track 43. In this way, when disassembling, the items close to the inside of the storage bin 1 can also be conveniently removed without manual entry to take them out. The electric drive is very labor-saving, and the linkage operation with the clamping part 5 is very clever.

[0030] Three sets of positioning parts 6 of different heights are installed on both sides of the shelf plate 2 above each shelf plate 2. The positioning part 6 includes a hollow block 61 fixed to the side wall of the shelf plate 2. An arc plug 63 is slidably arranged in an opening on one side of the hollow block 61. The arc plug 63 is connected to the side wall of the shelf plate 2 by a spring 63. A pull rope 64 is also fixed to this side of the arc plug 63. The pull rope 64 passes through the side wall of the shelf plate 2 and enters its inner cavity. The pull rope 64 is connected to a rotating rod 65 rotatably connected inside the shelf plate 2. The arc plug 63 can be inserted into the corresponding side walls of the three loading boxes 3. An arc groove 35 is provided, and the arc grooves 35 on the side walls of the three loading boxes 3 on one support plate 21 have different heights and correspond to the three arc surface plug-ins 63 on the same side. The side surface of the vertical plate 22 at one end close to the inner direction of the storage bin 1 is connected to the shelf plate 2 with a baffle 25, and the baffle 25 is fitted with the side wall of the innermost loading box 3. Two support rods 33 are symmetrically fixed to the side walls of the two loading boxes 3 on the support plate 21 close to the inner direction of the storage bin 1, and a rubber block 34 is fixed to one side of the support rod 33, and the rubber block 34 is fitted with the side wall of the loading box 3 at the adjacent end.

[0031] As described above, by designing the positioning portion 6, the stopper 33 and the baffle 25, the three positioning portions 6 have the same position specifications as the arc panel 23, and the arc surface of the arc surface plug block 63 is designed to face the outside of the storage bin 1. When the first loading box 3 is placed and moved inward, its side surface will only press it into the hollow block 61 when it fits with the first two arc surface plug blocks 63. The arc groove 35 is located at a high position and cannot be inserted by the arc surface plug block 63. When the loading box 3 moves to the innermost end and fits with the baffle 25, the arc surface plug block 63 at the highest position will be compressed and reach the arc groove 35. At this time, it can be ejected by spring three 63 and inserted into the arc groove 35, and then another two loading boxes 3 are put in. The other two arc-surface plug blocks 63 can be inserted into the corresponding arc grooves 35, so that the three loading boxes 3 are moved to the outside of the storage bin 1, and the adjacent loading boxes 3 are in contact and fit with the support rod 33 and the rubber block 34, so that the three loading boxes 3 cannot continue to move into the storage bin 1, and then the loading boxes 3 are effectively fixed. The design is the same as that of the clamping part 5, and it is also an automatic clamping, which enhances stability while ensuring that the placement speed is not affected.

[0032] A sealing plate 24 is fixed to the front opening of the frame plate 2, and the driving part 7 includes a column gear 71 rotatably connected to the inner side of the sealing plate 24, and two column gears 72 are meshed on both sides of the column gear 71. The column gear 72 is sleeved on the outside of the rotating rod 65, and the column gear 71 is connected to the rotating shaft with a rotating disk 73. The rotating disk 73 is located on the outside of the sealing plate 24. A circular hole 74 is provided on the rotating disk 73 and the sealing plate 24, and the two circular holes correspond when the rotating disk 73 rotates ninety degrees, and at this time the arc surface plug block 63 is retracted into the inside of the hollow block 61.

[0033] As mentioned above, through the driving part 2 7, when unloading, the arc surface plug block 63 needs to be retracted into the hollow block 61, so the block on one side of the rotating disk 73 can be pinched to rotate it, and then the column gear 1 71 is rotated, and the column gear 2 72 is driven to rotate so that the rotating rod 65 rotates to reel in the pull rope 64, and the pull rope pulls the arc surface plug block 63 to retract into the hollow block 61. At this time, the rotating disk 73 rotates ninety degrees, and the circular hole of the rotating disk 73 and a circular hole 74 on the sealing plate 24 can be inserted into the two holes with a separately designed small round tube, so that the arc surface plug block 63 cannot be reset, and then it can be quickly Unloading is very convenient and fast. Six arc-surface plug-ins 63 of the same height can be operated at one time, which solves the problem that all arc-surface plug-ins 63 are inconvenient to be separated from the arc groove 35, and increases the efficiency of unloading. After all the goods are unloaded, the small round tube is pulled out and the force is slowly loosened to allow the arc-surface plug-in 63 to be reset by spring three 63. It should be noted that the round hole 74 can also be a threaded hole design. When disassembling the position of the rotating disk 73, a screw can also be inserted. Moreover, the sealing plate 24 is located on the inner side of the frame plate 2 and will not collide with the outside world and become loose, making it safer and more reliable during transportation.

[0034] Three classification signs 26 are installed above each support plate 21 on both sides of the shelf plate 2 . The three classification signs 26 have different heights, and are all located at one side of the loading box 3 .

[0035] As mentioned above, the classification plate 26 is used to facilitate observation of the type of cargo box 31 on each loading box 3, and the specification design is the same as that of the curved panel, which is low outside and high inside, thereby avoiding obstruction and making observation very convenient.

[0036] Working principle: put the first loading box 3 into the support plate 21, and insert the protrusion 32 into the top slide groove of the support plate 21 to form a sliding connection, then place the cargo box 31 containing refrigerated goods on the loading box 3, and fit it with the adjacent surfaces of the two inner corners, then drive the loading box 3 to move into the storage bin 1 through the driving part 1 4, and fix the cargo box 31 inside the loading box 3 through the clamping part 5. At the same time, the position of the loading box 3 is fixed through the positioning part 6, completing the classified and stable placement operation. When disassembling, the clamping part 5 is automatically loosened as the loading box 3 moves outward, and the positioning part 6 can be loosened by the operation of the driving part 2 7, so that the goods can be easily taken out, which is very convenient.

[0037] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
