Description

Technical Field

[0001] The present invention relates to the technical field related to cold chain transportation, and in particular to a fixing frame for cold chain transportation. Background Art

[0002] Cold chain transportation refers to a transportation method in which the transported goods are always kept at a certain temperature during the entire transportation process, whether it is loading and unloading, changing the mode of transportation, changing the packaging equipment, etc., and currently road transportation is the main way of cold chain transportation. Cold chain transportation covers a wide range, including food, medicine, life sciences and cosmetics. During cold chain transportation, the carriage needs to maintain good sealing and needs to be used in conjunction with a logistics box. Reference publication number: "CN217917748U", the disclosed "a carriage structure for cold chain transportation" includes a carriage, a placement plate and a pad, the pad is fixedly arranged on the lower inner wall of the carriage, the placement plate is arranged above the pad, the upper surface of the placement plate is provided with a plurality of evenly distributed water leakage holes, and the lower side of the placement plate is fixedly provided with a plurality of evenly distributed support rods and placed on the pad through a plurality of support rods, the front and rear sides of the placement plate are respectively against the left and right inner walls of the carriage and can be slidably arranged, the upper side of the pad is provided with two front and rear symmetrically distributed water troughs, and the right side of the carriage is rotatably connected with two opposing compartment doors through hinges.

[0003] However, the internal fixing structure of the existing cold chain transport carriages is simple. When in use, the logistics boxes usually need to be stacked inside the carriage, and the fixing mechanism inside the traditional carriage can only provide a limiting effect for the logistics boxes on the bottom layer. Therefore, the overall stability is poor. At the same time, the stacking stacking method requires personnel to enter the carriage when loading and unloading the logistics boxes, which can easily cause internal contamination of the carriage. As the number of stacked logistics boxes increases, the operating space for personnel will gradually decrease, making the operation more difficult. At the same time, the stacking storage method will increase the difficulty and time required for loading and unloading, and can easily cause excessive cooling inside the carriage. Summary of the invention

[0006] Furthermore, the connection mode between the base frame and the movable frame is a rotational connection, and a group of limit plates are symmetrically installed on both sides of the edge of each base frame, and each group of limit plates is provided with a plurality of fixing seats at equal intervals.

[0007] Furthermore, the movable frame is connected to the control rod by rotational connection, and the control rod is connected to the connecting seat by threaded connection; the control rod, the connecting seat and the adapter constitute a sliding structure.

[0008] Furthermore, the control rod and the limiter are connected in a rotational manner, and the control rod, the limiter and the push rod form a sliding structure; Furthermore, the connection between the push rod and the first slide groove is a sliding connection, and the first slide groove and the movable frame are arranged relatively parallel; Furthermore, the second chute is arranged in an inclined manner, and the height of the rear end of the second chute is greater than the height of the front end.

[0009] Furthermore, the limiting plate and the inner frame are connected in a rotational manner, and the limiting plate, the spring plate, the first connecting rod and the second connecting rod form a rebound structure.

[0012] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that: 1. In the present invention, a base frame, a movable frame and a support rod are provided, and the whole is composed of the base frame, the movable frame and the guide frame, and can be vertically stacked and combined in conjunction with the support rod to adapt to carriages of different heights. In the initial state, the base frame, the movable frame and the guide frame are kept in parallel, and the top of the guide frame is an inward folding structure, and the inward folding structure at the front end of the guide frame is provided with a notch.

[0027] Specifically, the crank handle 7 can drive the control rod 6 to rotate as a whole.

[0028] As a further explanation of this embodiment, when the control rod 6 rotates, it cooperates with the connecting seat 23 so that the control rod 6 slides forward and backward while rotating, and the sliding direction is related to the rotation direction.

[0029] Please refer to Fig.11 As shown, in this embodiment, the control rod 6 is connected to the limit member 8 in a rotating manner, and the control rod 6, the limit member 8 and the top rod 9 form a sliding structure; the top rod 9 is connected to the first slide groove 10 in a sliding manner, and the first slide groove 10 is arranged relatively parallel to the movable frame 2; the second slide groove 11 is arranged in an inclined manner, and the height of the rear end of the second slide groove 11 is greater than the height of the front end.

[0030] Specifically, when the control rod 6 slides forward and backward, it will drive the push rod 9 to slide forward and backward synchronously.

[0031] As a further explanation of this embodiment, when the control rod 6 slides backward, it cooperates with the second sliding groove 11 at the rear end which is inclined upward, so as to drive the rear end of the movable frame 2 to rotate upward as a whole.

[0032] Please refer to Fig.12 , Fig.14 and Fig.16 As shown, in this embodiment, the connection mode of the limit plate 12 and the inner frame 5 is a rotational connection, and the limit plate 12, the spring plate 13, the first connecting rod 14 and the second connecting rod 15 form a rebound structure.

[0033] More specifically, when the material box 21 slides backward along the guide frame 4 , the bottom of the material box 21 contacts the limit plate 12 , which pushes the limit plate 12 to flip backward and squeeze the spring plate 13 . The rotated limit plate 12 is reset by the rebound of the spring plate 13 .

[0034] As a further illustration of this embodiment, the front side of the limiting plate 12 is an inclined structure, and the rear side of the limiting plate 12 is a vertical plane structure.

[0035] Please refer to Fig.12 , Fig.14 and Fig.16 As shown, in this embodiment, the first connecting rod 14 and the first limiting groove 16 are connected in a sliding manner; the second connecting rod 15 and the second limiting groove 17 are connected in a sliding manner; and the first limiting groove 16 and the second limiting groove 17 are both arc-shaped structures.

[0036] Specifically, the first limiting groove 16 and the second limiting groove 17 respectively limit the movable range of the first connecting rod 14 and the second connecting rod 15 .

[0037] As a further illustration of this embodiment, the arc centers of the first limiting groove 16 and the second limiting groove 17 coincide with the rotation axis of the limiting plate 12 .

[0038] Please refer to Fig.12 , Fig.13 , Fig.15 and Fig.18 As shown, in this embodiment, the connection mode between the synchronization block 18 and the transfer rod 19 is a rotational connection, and the connection mode between the transfer rod 19 and the adapter 20 is a rotational connection; the control rod 6, the adapter 20, the transfer rod 19 and the synchronization block 18 form a rotation structure.

[0039] Specifically, in the initial state, the adapter 20 slides along with the control rod 6 and cooperates with the adapter rod 19 to push the synchronization block 18 to rotate synchronously.

[0040] As a further explanation of this embodiment, the synchronous block 18 will drive the first connecting rod 14, the second connecting rod 15 and the limit plate 12 to flip forward synchronously while rotating, so that the limit plate 12 is separated from the bottom of the material box 21, and the material box 21 in the guide frame 4 can slide forward.

[0041] The working principle of the present invention is as follows: when in use, firstly, according to the height of the carriage, multiple base frames 1 are stacked vertically with the fixing seats 24 and the support rods 22, and are fixedly installed inside the carriage with bolts. When the material box 21 needs to be loaded, the bottom of the material box 21 is placed between the two guide frames 4 through the groove on the front side of the top of the guide frame 4, and then the material box 21 is pushed backward so that the bottom of the material box 21 slides backward along the inside of the two guide frames 4. During this process, when the bottom of the material box 21 contacts the limit plate 12, it pushes the limit plate 12 backward and squeezes the two correspondingly connected spring plates 13. After the material box 21 passes, the spring plate 13 drives the limit plate 12 to reset by rebounding, and makes the limit plate 12 re-engage with the bottom teeth of the material box 21 to prevent the material box 21 from sliding forward. Repeat the operation until all the material boxes 21 are installed inside the guide frames 4. When the guide frame 4 needs to be unloaded, the crank handle 7 is first turned clockwise to drive the control rod 6 to rotate synchronously. Then, the rotating control rod 6 starts to slide to the rear side under the meshing action of the connecting seat 23, thereby driving the push rod 9 to slide backward along the first slide groove 10 synchronously. At the same time, the two ends of the push rod 9 slide backward along the two second slide grooves 11. At this time, the height of the push rod 9 gradually increases, thereby driving the rear end of the movable frame 2 to tilt upward as a whole, so that the movable frame 2 is higher at the back and lower at the front, forming a height difference; When the control rod 6 slides backward, it will drive all the adapters 20 to slide backward synchronously, and then cooperate with the adapter rod 19 to push the corresponding connected synchronization block 18 to flip upward. The upward flipped synchronization block 18 drives the first connecting rod 14 and the second connecting rod 15 to start sliding upward along the first limit groove 16 and the second limit groove 17 respectively. At the same time, the limit plate 12 and the spring plate 13 follow and slide forward synchronously and then separate from the material box 21. The material box 21 that has lost its restriction will naturally slide forward under the action of the height difference, which is convenient for unloading.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
