[0021] 1. The adjustable mechanism allows for the adjustment of the position of the partition inside the compartment, thereby dividing the interior space and achieving a horizontal double-layer configuration. This improves the convenience of loading goods and allows for the control of different refrigeration temperatures in the divided spaces, which helps improve the accuracy of temperature control. At the same time, adjusting the partition allows for the adjustment of the volume of the divided spaces, which is beneficial for adapting to the space required by goods with different temperature requirements, thus improving the space utilization rate of the adjustable double-layer refrigerated truck compartment.

[0022] 2. The sliding door can slide inside the slide groove via the inner and outer sliding blocks, which facilitates the sliding opening of the door. This reduces the space required for opening traditional swing doors and improves the usability. The positioning mechanism can conveniently position the closed sliding door, ensuring the stability of the adjustable double-layer refrigerated truck compartment during transportation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 This utility model provides a technical solution: an adjustable double-layer refrigerated truck compartment, including a compartment 1, with symmetrically opened mounting slots 2 for installing refrigeration equipment on the top of the compartment 1, a partition 3, which is slidably installed inside the compartment 1 to achieve a horizontal double-layer partition of the interior space of the compartment 1, and an adjustment mechanism connected between the compartment 1 and the partition 3 to achieve position adjustment of the partition 3. The adjustment mechanism includes a limiting seat 4 symmetrically installed on the top of the compartment 1, an adjusting screw 5 rotatably installed inside the limiting seat 4, a slider 6 threaded on the outer ring of the adjusting screw 5, and the bottom of the slider 6 fixedly connected to the partition 3. The adjustment mechanism also includes a pulley 7 fixedly installed on the left end of the adjusting screw 5, a toothed belt 8 connected between the pulleys 7, and a rotating wheel 9 fixedly installed on the right end of the adjusting screw 5.

[0032] The design of the above structure allows the rotation of the single-sided rotating wheel 9 to drive the corresponding adjusting screw 5 to rotate inside the corresponding limiting seat 4. Then, this adjusting screw 5 drives the other adjusting screw 5 to rotate inside the corresponding limiting seat 4 through the transmission structure composed of the pulley 7 and the toothed belt 8. At this time, the two sets of adjusting screws 5 rotate in the same direction, and can drive the slider 6 and the partition 3 to slide. This is beneficial for the partition 3 to adjust the volume of the transverse double-layer space inside the compartment 1 when sliding, and can accurately control the temperature inside each space after volume adjustment. Moreover, the space volume adjustment can adapt to the loading requirements of the goods and improve the space utilization rate.

[0033] A fixed plate 10 is symmetrically fixedly installed on the front side of the compartment 1. A sliding door 14 is also symmetrically slidably installed on the front side of the compartment 1. A handle 15 is fixedly installed on the bottom front side of the sliding door 14. Sliding grooves 11 are symmetrically opened on the front sides of the upper and lower ends of the compartment 1. An inner slide seat 12 and an outer slide seat 13 are slidably installed inside the sliding groove 11. The front ends of the inner slide seat 12 and the outer slide seat 13 are fixedly connected to the sliding door 14.

[0034] The design of the above structure allows the sliding door 14 to slide forward by pulling the handle 15 forward, and the inner slide block 12 and the outer slide block 13 to slide forward inside the slide groove 11. Then, by pulling the handles 15 in the opposite direction, the sliding door 14 can be opened in a sliding manner, and by pulling in opposite directions, the sliding door 14 can be closed, effectively reducing the space required to open a traditional swing door.

[0035] A positioning mechanism is connected between the sliding door 14 and the compartment 1 to position the closed sliding door 14. The positioning mechanism includes a positioning seat 16 fixedly installed on the front side of the sliding door 14. A lifting screw 17 passes through the interior of the positioning seat 16. A knob 18 is fixedly connected to the bottom end of the lifting screw 17. A connecting seat 19 is rotatably sleeved on the top end of the lifting screw 17. A lifting seat 20 is fixedly installed on the outer ring of the connecting seat 19. A fixed seat 21 passes through the bottom of the lifting seat 20. The lifting seat 20 and the fixed seat 21 are slidably connected. The fixed seat 21 is fixedly connected to the sliding door 14. The positioning mechanism also includes a connecting plate 22 fixedly installed on the outer ring of the connecting seat 19. A locking block 23 is fixedly installed at the end of the connecting plate 22 away from the connecting seat 19. The upper and lower sides of the compartment 1 are symmetrically provided with locking slots 24. The locking block 23 is slidably connected to the upper inner sliding seat 12. The locking block 23 and the locking slot 24 are movably engaged.

[0036] The design of the above structure allows the lifting screw 17 to move up and down inside the positioning seat 16 by rotating the knob 18 in both directions. This, in turn, uses the connecting seat 19, which is rotated at the top, to move the lifting seat 20, the connecting plate 22, and the locking block 23 up and down. The fixed seat 21 limits the movement of the lifting seat 20, the connecting plate 22, and the locking block 23, ensuring a vertical position. The locking block 23 can then move up and down inside the inner slide seat 12 on the upper side, controlling its engagement and disengagement from the slot 24. When the sliding door 14 is closed, it can be positioned by engagement, and when the sliding door 14 needs to be opened, it can be released by disengagement, improving the stability of the sliding door 14 when closing and the ease of operation when opening.

[0037] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
