[0033] Please see Figure 1 , 2 As shown in Figure 3, this utility model discloses a pull-out rack structure for a refrigerated and insulated truck. The pull-out rack structure 4 is installed inside the truck compartment 1. The pull-out rack structure 4 includes a left connecting plate 41 and a right connecting plate 42 installed on both sides of the truck compartment 1. The left connecting plate 41 and the right connecting plate 42 are slidably connected to a lower crossbeam 45. The lower crossbeam 45 is fixedly connected to an upper crossbeam 46. The lower crossbeam 45 and the upper crossbeam 46 are provided with limiting grooves and / or limiting holes at corresponding positions for limiting the support beam 50.

[0034] Specifically, a support member 48 and a pin 51 are provided between the lower crossbeam 45 and the upper crossbeam 46. The support member 48 is fixedly connected to the lower crossbeam 45 and the upper crossbeam 46. The pin 51 is used to limit the support beam 50 within the limiting groove group 47 or the limiting hole. The pin 51 includes a first pin 511, a second pin 512, a third pin 513, a fourth pin 514, and a fifth pin 515. The first pin 511 and the second pin 512 are disposed between the first lower crossbeam 451 and the first upper crossbeam 461, and the first pin 511 is also installed at one end of the first support beam 501. The first pin 511 and one end of the first support beam 501 are limited within the first limiting groove group 471; the second pin 512 is also installed at one end of the second support beam 502, and one end of the second pin 512 and one end of the second support beam 502 are limited within the second limiting groove group 472; the third pin 513 and the fourth pin 514 are disposed between the second lower crossbeam 452 and the second upper crossbeam 462, and the third pin 513 is also installed at one end of the second support beam 501. At the other end of the support beam 502, the third pin 513 and the other end of the second support beam 502 are limited within the third limiting groove group 473; the fourth pin 514 is simultaneously installed at the other end of the first support beam 501, and the other ends of the fourth pin 514 and the first support beam 501 are limited within the fourth limiting groove group 474; the fifth pin 515 is disposed between the third upper crossbeam 463 and the third lower crossbeam 453, and the fifth pin 515 passes through the through hole at the intersection of the center positions of the first support beam 501 and the second support beam 502, and the fifth pin 515 limits the first support beam 501 and the second support beam 502 within the limiting through hole.

[0035] Preferably, the left connecting plate 41 and the right connecting plate 42 are semi-open U-shaped channels, and a slide rail fixing frame 43 is also provided inside the left connecting plate 41 and the right connecting plate 42. The slide rail fixing frame 43 houses a pulley assembly 44. The pulley assembly 44 is respectively installed at both ends of the lower crossbeam 45. The pull-out shelf structure 4 connects the third support beam 503 and the fourth support beam 504. The other end of the third support beam 503 and the fourth support beam 504 is connected to a locking structure 52, and a handle 521 is provided on the locking structure 52.

[0036] Example 1, see Figure 1 , 2 As shown in Figures 3, 4, 6, and 7, this device is installed inside a refrigerated and insulated truck. First, the truck compartment 1 has a built-in insulated compartment structure 2. A left connecting plate 41 and a right connecting plate 42 are respectively installed on the left and right sides of the pull-out rack structure 4. The left connecting plate 41 and the right connecting plate 42 are fixed to the two sides of the compartment structure 2 by rivets 5, so that the pull-out rack structure 4 and the built-in insulated compartment structure 2 become a whole. The refrigerated and insulated truck pull-out rack structure 4 also becomes the middle support for the cargo boxes 3 inside the built-in insulated compartment structure 2. When loading small cargo boxes, the refrigerated and insulated truck pull-out rack structure 4 is unfolded. Of course, multiple pull-out rack structures can be installed in the compartment to accommodate more cargo boxes 3. The appropriate height of the pull-out rack structure 4 can also be selected according to the size of the cargo boxes, thereby realizing the function of the refrigerated and insulated truck pull-out rack structure 4 in terms of opening and closing.

[0037] Example 2, see Figure 1 , 2 Figures 3, 4, 5, 6, 7, and 8 illustrate the assembly process of this device inside the insulated truck compartment. As shown, first, after fixing the left connecting plate 41 and the right connecting plate 42 inside the compartment, the left connecting plate 41 and the right connecting plate 42 are semi-open U-shaped grooves, as shown... Figure 5 As shown, the lower arms of the left connecting plate 41 and the right connecting plate 42 are longer and the upper arms are shorter. The left connecting plate 41 and the right connecting plate 42 are also equipped with slide rail fixing frames 43. The slide rail fixing frames 43 contain pulley groups 44. The pulley groups 44 are installed at both ends of the lower crossbeam 45. That is, the first lower crossbeam 451, the second lower crossbeam 452 and the third lower crossbeam 453 are respectively installed and fixed to the slide rail fixing frames 43 in the left and right connecting plates. Then, the first support beam 501, the second support beam 502, the third support beam 503 and the fourth support beam 504 are respectively installed into the limiting grooves and fixed in sequence by pins. Then, the first upper crossbeam 461, the second upper crossbeam 462 and the third upper crossbeam 463 are respectively installed to form a set of pull-out shelf structures 4. The number of pull-out shelf structures 4 can be one or more sets depending on the length of the carriage.

[0038] For details, see Figure 3 , Figure 7 The diagram shown illustrates the unfolded (opened) state of the pull-out shelf structure 4 of this utility model. (See attached image.) Figure 8 As shown, the pull-out shelf structure 4 is in the folded (closed) state. It can be seen that after being folded, this device occupies a small amount of space in the carriage, making it easy to load large items into the carriage.

[0039] For details, see Figure 7 The diagram shows the open state of this structure. The specific operation is as follows: When the pull-out shelf structure 4 is opened, the locking structure 52 is released, and the handle 521 is pulled outwards. The first support beam 501 and the second support beam 502 rotate outwards around the pin 515 under external force. Simultaneously, the first support beam 501 and the second support beam 502 slide inwards within the limiting groove, causing the upper and lower crossbeams to slide outwards along the left connecting plate 41 and the right connecting plate 42, i.e., outwards from the carriage, thus unfolding the pull-out shelf structure 4. Once the desired position is reached, the locking structure 52 is closed to limit the movement, and the pull-out shelf remains in the required position for easy goods handling. To fully open the pull-out shelf structure, it can be pulled outwards until the structure is fully open. (See also...) Figure 8 The diagram shows the retractable shelving structure in its stored state. The specific operation for storing the shelving structure is as follows: Open the locking mechanism 52, grasp the handle 521 and push it inwards. Under the action of external force, the first support beam 501 and the second support beam 502 rotate inwards around the pin 515. Simultaneously, the first support beam 501 and the second support beam 502 slide inwards in the limiting groove, causing the upper and lower crossbeams to slide inwards along the left connecting plate 41 and the right connecting plate 42, i.e., in the direction inside the carriage, until the shelving structure is pushed to a position where it cannot be pushed any further. Then, lock the locking mechanism 52 to secure it. This device has a small volume after storage, greatly saving space inside the carriage and facilitating the transportation of large goods. The space inside the carriage is no longer limited by fixed shelving. Furthermore, the locking mechanism 52, in conjunction with the shelving structure 4, allows the shelving to be stopped at any position inside the carriage and then secured by the locking mechanism 52. This provides stable use, convenient operation, and solves the different needs of items inside the carriage.

[0040] This device has a simple structure, is easy to install, and has flexible pull-out operation, which is conducive to the transportation of goods of various sizes. The pull-out shelf structure can also be used or stored according to the size of the cargo box, with a reasonable space layout. It is suitable for modification and use in most box trucks and refrigerated trucks on the market. Moreover, the materials are common and the cost is low, making it suitable for promotion and use in the market.

[0041] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
