Description

Technical Field

[0001] This utility model relates to the field of cold chain transportation, and in particular to a cargo anti-shifting fixing frame for cold chain transportation vehicles. Background Technology

[0002] Cold chain transport vehicles are the core carriers for achieving cold chain transportation. They can rapidly lower the temperature inside the vehicle to a target range and maintain it in real time through mechanical refrigeration or liquid nitrogen cooling, and are widely used in the food and pharmaceutical industries. Compared to ordinary transportation, cold chain transportation effectively slows down the spoilage rate of goods and reduces the loss rate. During the transportation of goods using cold chain transport vehicles, the goods typically need to be placed on shelves.

[0003] In related technologies, the interior of cold chain transport vehicles mainly relies on shelves to support the transported goods. Traditional shelves are usually in the form of multiple shelves, on which personnel can place goods. However, due to the bumps that occur during vehicle operation, in order to improve the stability of goods placement, it is usually necessary to evenly set limit strips on the shelves and set placement strips at the bottom of the cargo box. Thus, when placing goods, the placement strips can be positioned between the two limit strips. The stability of the placed goods can be improved by the cooperation of the limit strips and the placement strips.

[0004] However, when the vehicle experiences significant or prolonged bumps, the placement strips of the cargo box may slide along the direction of the limit strips, potentially affecting the stability of cargo transportation.

[0005] Therefore, it is necessary to provide a cargo anti-shifting fixing bracket for cold chain transport vehicles to solve the above problems. Utility Model Content

[0006] To address the technical problem that the placement strip of the cargo box may slide along the direction of the limiting strip, which may affect the stability of cargo transportation, this utility model provides a cargo anti-shifting fixing frame for cold chain transport vehicles.

[0007] This utility model provides a cargo anti-shifting fixing frame for cold chain transport vehicles, comprising: symmetrically arranged support frames, with multiple shelves evenly fixedly connected between the symmetrically arranged support frames, and cargo boxes, limiting strips, and placement strips placed on the shelves. Several limiting strips are evenly fixedly arranged on the upper surfaces of the multiple shelves. Several placement strips are symmetrically arranged in pairs on the lower surface of each cargo box, with the placement strips located between adjacent limiting strips. Several adjusting components are provided, each adjusting component being movably disposed inside each placement strip. A straight connector is symmetrically hinged to both sides of each adjusting component. A limiting post is hinged to the end of the straight connector away from the adjusting component. The end of the limiting post away from the straight connector is movably inserted into the inner wall of the limiting strip to restrict the movement between the placement strip and the limiting strip, thereby improving the stability of the cargo box.

[0008] Preferably, the support frame includes symmetrically arranged rectangular columns, one side of the shelf is fixedly connected to one side of the rectangular column, a base plate is fixedly connected to the lower end face of the rectangular column, and multiple reinforcing plates are uniformly fixedly connected between the symmetrically arranged rectangular columns.

[0009] Preferably, the limiting strip includes a first rectangular strip, the lower surface of the first rectangular strip is fixedly connected to the upper surface of the layer plate, and a plurality of limiting slots are evenly provided on both sides of the first rectangular strip.

[0010] Preferably, the placement strip includes a second rectangular strip, the upper surface of which is fixedly connected to the lower surface of the cargo box, and a storage slot is provided inside the second rectangular strip. The adjustment component and the straight connector are both located inside the storage slot. Storage holes communicating with the storage slot are provided on both sides of the second rectangular strip, and each of the limiting pins is located inside each of the storage holes.

[0011] Preferably, the adjustment assembly includes a shaft, the outer wall of which is rotatably connected to the inner wall of the second rectangular strip, a butterfly-shaped adjustment head is fixedly connected to one end of the shaft, a connecting post is fixedly connected to the outer wall of the shaft, the connecting post is located inside the storage slot, and ear plates are symmetrically fixedly connected to the outer wall of the connecting post, with each ear plate corresponding to one end of each of the straight connectors being hinged to each other.

[0012] Preferably, a first sub-magnetic piece is fixedly connected to the clockwise side of the ear plate, and two first female magnetic pieces are fixedly connected to the inner wall of the second rectangular strip. The side of the first sub-magnetic piece away from the ear plate is magnetically connected to one side of the first female magnetic piece. A second sub-magnetic piece is fixedly connected to the counterclockwise side of the ear plate, and two second female magnetic pieces are fixedly connected to the inner wall of the second rectangular strip.

[0013] Compared with related technologies, the cargo anti-shifting fixing bracket for cold chain transport vehicles provided by this utility model has the following beneficial effects:

[0014] 1. This cargo anti-shifting fixing frame for cold chain transport vehicles can significantly improve the stability of the cargo box during transportation: The symmetrically arranged support frame can restrict the installation position of multiple shelves. The shelves are used to place the cargo box. Several limiting strips are evenly fixedly connected to the upper surface of the shelf. Placement strips are symmetrically fixedly installed on the lower surface of the cargo box. The placement strips are located between adjacent limiting strips and can play a certain limiting role for the cargo box. An adjustment component is movably installed in the placement strip. Rotating the adjustment component counterclockwise can drive the two side connecting pieces to rotate, which in turn can push the limiting pin to move and insert into the inner wall of the limiting strip. This can limit the position between the placement strip and the limiting strip, preventing the placement strip from sliding along the direction of the limiting strip due to large vehicle bumps or long periods of time. This can significantly improve the stability of the cargo box during transportation and reduce the risk of damage or deterioration of goods due to displacement.

[0015] 2. This cargo anti-shifting fixing frame for cold chain transport vehicles supports the shelves through rectangular columns, and the bottom plate increases the contact surface with the bottom of the cold chain compartment, improving the stability of the rectangular columns. Multiple horizontally distributed reinforcing plates enhance the stability between the symmetrically arranged rectangular columns. The first rectangular strip provides a certain limit to the placement strip, and the limit slot can be inserted with the limit plug to improve the limiting effect between the first rectangular strip and the placement strip. The width of the second rectangular strip is slightly smaller than the distance between two adjacent limit strips to facilitate embedding between adjacent limit strips. The storage slot restricts the installation position of the adjustment component and the straight connector, and the storage hole guides the movement of the limit plug.

[0016] 3. This cargo anti-shifting fixing bracket for cold chain transport vehicles can control the rotation of the axle through a butterfly-shaped adjustment head. The rotation of the axle drives the rotation of the connecting column, which in turn drives the movement of the externally fixed ear plates. The movement of the ear plates can move the straight connector from one end. Adjusting the limit pin and the limit strip to insert them, the two ear plates rotate counterclockwise to a horizontal state, and the first male magnetic absorbing piece can magnetically attract the first female magnetic absorbing piece, thereby improving the stability of the limit pin during use. Adjusting the limit pin and the limit strip to separate, the two ear plates rotate clockwise to a vertical state, and the second male magnetic absorbing piece can magnetically attract the second female magnetic absorbing piece, thereby restricting the storage position of the limit pin.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 6A cargo anti-shifting fixing frame for cold chain transport vehicles includes: symmetrically arranged support frames 1, with multiple shelves 2 evenly fixedly connected between the symmetrically arranged support frames 1, and cargo boxes 3, limiting strips 4, and placement strips 5 placed on the shelves 2. Several limiting strips 4 are evenly fixedly arranged on the upper surfaces of the multiple shelves 2, and several placement strips 5 are symmetrically and correspondingly fixedly arranged on the lower surface of each cargo box 3, with the placement strips 5 located between adjacent limiting strips 4. Several adjusting components 6 are provided, each adjusting component 6 being movably disposed inside each placement strip 5. A straight connector 7 is symmetrically hinged to both sides of the adjusting component 6, and a limiting pin 8 is hinged to the end of the straight connector 7 away from the adjusting component 6. The end of the limiting pin 8 away from the straight connector 7 is movably inserted into the inner wall of the limiting strip 4 to restrict the movement between the placement strip 5 and the limiting strip 4, thereby improving the stability of the cargo box 3.

[0026] In the specific implementation process, the symmetrically arranged support frame 1 in the cold chain transport vehicle cargo anti-shifting fixing frame can restrict the installation position of multiple shelves 2. The shelves 2 are used to place the cargo boxes 3 that need to be transported by the cold chain transport vehicle. Furthermore, several limiting strips 4 are evenly fixedly connected to the upper surface of the shelf 2, and placement strips 5 are symmetrically fixedly installed on the lower surface of the cargo box 3. Specifically, when the cargo box 3 is placed on the shelf 2, the placement strips 5 can be located between adjacent limiting strips 4, so that the placement strips 5 and the limiting strips 4 can play a certain limiting role for the cargo box 3.

[0027] Furthermore, an adjustment component 6 is movably installed within the placement strip 5. On both sides of the adjustment component 6, symmetrically hinged straight connectors 7 are connected. Rotating the adjustment component 6 causes one end of the straight connector 7 to rotate around the adjustment component 6, achieving force transmission and direction conversion. The end of the straight connector 7 furthest from the adjustment component 6 is hinged to a limiting post 8. When the straight connector 7 rotates, the limiting post 8 moves accordingly, changing its position. Specifically, when it is necessary to fix the cargo box 3, rotating the adjustment component 6 counterclockwise causes the straight connectors 7 on both sides to rotate, thereby pushing the limiting post 8 to extend to both sides, allowing the end of the limiting post 8 furthest from the straight connector 7 to movably engage with the inner wall of the limiting strip 4. This insertion action restricts the relative displacement between the placement strip 5 and the limiting strip 4, preventing the placement strip 5 from sliding along the limiting strip 4 due to large vehicle bumps or prolonged periods of time. This significantly improves the stability of the cargo box 3 during transportation and reduces the risk of damage or spoilage of goods due to displacement. When the cargo box 3 needs to be retrieved, the adjusting component 6 is rotated clockwise, causing the two side connectors 7 to rotate. This pulls the limiting pin 8 inward, separating the end of the limiting pin 8 away from the connector 7 from the limiting strip 4. This movement releases the restriction between the placement strip 5 and the limiting strip 4, making it easier to move and retrieve the cargo box 3.

[0028] See Figure 1 , Figure 2 and Figure 3 As shown, the support frame 1 includes symmetrically arranged rectangular columns 101. One side of the shelf 2 is fixedly connected to one side of the rectangular column 101. A base plate 102 is fixedly connected to the lower end face of the rectangular column 101. Multiple reinforcing plates 103 are evenly fixedly connected between the symmetrically arranged rectangular columns 101.

[0029] In the specific implementation process, the symmetrically arranged rectangular columns 101 are the core support components. One side of the shelf 2 can be fixed to one side of the rectangular column 101 by welding or high-strength bolts. The base plate 102 can increase the contact surface with the bottom of the cold chain compartment, improve the stability of the rectangular column 101, and the base plate 102 can be fixed to the bottom of the cold chain compartment as needed by expansion bolts to further prevent the support frame 1 from sliding in the compartment. Multiple reinforcing plates 103 are evenly fixed and connected between the symmetrically arranged rectangular columns 101. The stability between the symmetrically arranged rectangular columns 101 can be improved by multiple horizontally distributed reinforcing plates 103.

[0030] See Figure 2 , Figure 4 and Figure 5 As shown, the limiting strip 4 includes a first rectangular strip 401, the lower surface of the first rectangular strip 401 is fixedly connected to the upper surface of the layer plate 2, and a plurality of limiting slots 402 are evenly provided on both sides of the first rectangular strip 401.

[0031] In the specific implementation process, the first rectangular strip 401 can play a certain limiting role on the placement strip 5. The limiting slot 402 can be inserted with the limiting post 8, which can improve the limiting effect between the first rectangular strip 401 and the placement strip 5.

[0032] See Figure 4 , Figure 5 and Figure 6 As shown, the placement strip 5 includes a second rectangular strip 501. The upper surface of the second rectangular strip 501 is fixedly connected to the lower surface of the cargo box 3. The interior of the second rectangular strip 501 is provided with a storage slot 502. The adjustment component 6 and the straight connector 7 are both located inside the storage slot 502. Both sides of the second rectangular strip 501 are provided with storage holes 503 that communicate with the storage slot 502. Each limiting post 8 is located inside each storage hole 503.

[0033] In the specific implementation process, the width of the second rectangular strip 501 is slightly smaller than the distance between the two adjacent limiting strips 4, so that the placement strip 5 can be smoothly embedded between the adjacent limiting strips 4. The opening of the storage slot 502 can restrict the installation position of the adjustment component 6 and the straight connector 7. The opening of the storage hole 503 can guide the movement of the limiting plug 8.

[0034] See Figure 4 , Figure 5 and Figure 6 As shown, the adjustment assembly 6 includes a shaft 601, the outer wall of which is rotatably connected to the inner wall of the second rectangular bar 501. One end of the shaft 601 is fixedly connected to a butterfly adjustment head 602. A connecting post 603 is fixedly connected to the outer wall of the shaft 601. The connecting post 603 is located inside the storage slot 502. Ear plates 604 are symmetrically fixedly connected to the outer wall of the connecting post 603. Each ear plate 604 is hinged to one end of each straight connector 7.

[0035] In the specific implementation process, the user can control the rotation of the shaft 601 through the butterfly adjustment head 602. The rotation of the shaft 601 can drive the connecting column 603 to rotate. When the connecting column 603 rotates, it can drive the externally fixed ear plate 604 to move. The movement of the ear plate 604 can drive the straight connector 7 to move from one end.

[0036] See Figure 4 and Figure 5As shown, a first sub-magnetic piece 9 is fixedly connected to the clockwise side of the ear plate 604, and two first female magnetic pieces 10 are fixedly connected to the inner wall of the second rectangular strip 501. The side of the first sub-magnetic piece 9 away from the ear plate 604 is magnetically connected to the side of the first female magnetic piece 10. A second sub-magnetic piece 11 is fixedly connected to the counterclockwise side of the ear plate 604, and two second female magnetic pieces 12 are fixedly connected to the inner wall of the second rectangular strip 501.

[0037] In the specific implementation process, when the limiting plug 8 is inserted into the limiting strip 4 and the two ear plates 604 are rotated counterclockwise to a horizontal state, the first sub-magnetic suction piece 9 can be magnetically attracted to the first female magnetic suction piece 10, thereby improving the stability of the limiting plug 8 during use. When the limiting plug 8 is separated from the limiting strip 4 and the two ear plates 604 are rotated clockwise to a vertical state, the second sub-magnetic suction piece 11 can be magnetically attracted to the second female magnetic suction piece 12, thereby restricting the storage position of the limiting plug 8 so that personnel can take and put away the cargo box 3.

[0038] Specifically, it should be noted that both the sub-magnetic and main magnetic plates can be made of strong magnetic materials and treated with anti-oxidation to reduce the impact of low-temperature environments on magnetic attraction.

[0039] The working principle of the cargo anti-shifting fixing bracket for cold chain transport vehicles provided by this utility model is as follows:

[0040] When the cargo anti-shifting fixing frame for cold chain transport vehicles is in operation, the rectangular column 101 of the support frame 1 serves as the core support component. One side of the shelf 2 is fixed to the rectangular column 101. The bottom plate 102 increases the contact surface with the bottom of the vehicle compartment, and the reinforcing plate 103 improves the stability between the rectangular columns 101. The cargo box 3 is placed on the shelf 2, and the placement strip 5 on the lower surface of the cargo box 3 is embedded between the adjacent limiting strips 4, which plays a preliminary limiting role. When it is necessary to fix the cargo box 3, the butterfly adjusting head 602 of the adjusting component 6 is rotated counterclockwise. The shaft 601 drives the connecting column 603 to rotate, and the ear plate 604 moves accordingly. Through the straight connector 7, the limiting insert 8 is pushed out from the placement hole 503 to both sides. The limiting slot 402 of the limiting strip 4 is inserted to limit the relative displacement between the placement strip 5 and the limiting strip 4, thereby improving the stability of the cargo box 3. At this time, the first sub-magnetic piece 9 on the clockwise side of the ear plate 604 is magnetically attracted to the first female magnetic piece 10 on the inner wall of the second rectangular strip 501, stabilizing the limiting post 8. When taking out the cargo box 3, the butterfly adjusting head 602 is rotated clockwise, and the shaft 601 drives the connecting post 603 to rotate in the opposite direction. The ear plate 604 pulls the limiting post 8 to move inward through the straight connector 7, separating it from the limiting strip 4. The second sub-magnetic piece 11 on the counterclockwise side of the ear plate 604 is magnetically attracted to the second female magnetic piece 12, limiting the storage position of the limiting post 8, making it easier to take out and put out the cargo box 3.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
