[0025] The following is a more detailed description of the insulated meal delivery vehicle of the present invention, with reference to schematic diagrams, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art may modify the present invention as described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as a general guide for those skilled in the art and not as a limitation of the present invention.

[0026] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0027] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a heat-insulating food delivery vehicle, comprising a vehicle frame 1, a heat-insulating box 2, a fixed magnet 3, and a lifting and adjusting member.

[0028] Specifically, the vehicle frame 1 has a support platform, and a lifting hole 4 matching the fixed magnet 3 is formed through the support platform.

[0029] The heat preservation box 2 is mounted on the support platform, and the bottom surface of the heat preservation box 2 is magnetically attracted to the fixed magnet 3 .

[0030] The lifting adjustment member is installed on the bottom surface of the frame 1, and the top surface of the lifting adjustment member is fixedly connected to the fixed magnet 3. The lifting adjustment member is used to adjust the height of the fixed magnet 3 and adsorb and fix the thermal insulation box 2.

[0031] In this embodiment, when the insulated box 2 needs to be fixed, the insulated box 2 is placed on the support platform, and then the height of the fixing magnet 3 is changed using the lifting adjustment member so that the fixing magnet 3 passes through the lifting hole 4 and is fixedly adsorbed on the bottom surface of the insulated box 2, completing the fixing operation of the insulated box 2. When the insulated box 2 needs to be disassembled, the height of the fixing magnet 3 is lowered using the lifting adjustment member so that the fixing magnet 3 is separated from the insulated box 2. At this time, the fixing magnet 3 releases its adsorption and fixation on the insulated box 2, and the operator can remove the insulated box 2 from the support platform, thereby facilitating the disinfection and cleaning of the interior of the insulated box 2, while also ensuring the safety of the insulated box 2.

[0032] In a specific embodiment, in order to facilitate the movement of the dining cart, a push-pull handle 5 is provided on the top edge of the thermal insulation box 2, and a plurality of universal wheels 6 are installed on the bottom surface of the support platform.

[0033] It should be noted that the thermal insulation box 2 has multiple functional partitions, and each functional partition is independently provided with a thermal insulation door 7. Different functional partitions can be used to place different dishes or rice to prevent the taste of different dishes from mixing. In addition, a door lock 8 is provided between the thermal insulation door 7 and the thermal insulation box 2 to facilitate closing the thermal insulation door 7 to keep the food warm.

[0034] Furthermore, a positioning frame 9 is provided on the top surface of the supporting platform, and the top end of the positioning frame 9 has a chamfered structure.

[0035] Specifically, the cross section of the positioning frame 9 is in a right angle shape, four positioning frames 9 are provided, and the four positioning frames 9 are distributed on the support platform in a rectangular shape.

[0036] In this embodiment, the insulated box 2 is placed between two positioning frames 9. These four positioning frames 9 position the corners of the insulated box 2, effectively reducing horizontal sliding of the insulated box 2 on the support platform. Furthermore, the fixing magnets 3 reduce vertical displacement of the insulated box 2. These two factors combine to effectively ensure the stability of the insulated box 2.

[0037] Furthermore, the lifting and adjusting component includes a positioning and mounting frame 10 , a driving platform 11 and an adjusting screw rod 12 .

[0038] Specifically, the positioning and mounting frame 10 is fixedly mounted on the bottom surface of the vehicle frame 1 .

[0039] The driving platform 11 is slidably arranged along the length direction of the positioning and mounting frame 10 , and the fixed magnet 3 is fixedly mounted on the driving platform 11 .

[0040] The adjusting screw rod 12 is rotatably mounted on the driving platform 11 , and the adjusting screw rod 12 is threadedly connected to the driving platform 11 .

[0041] In this embodiment, the end of the adjusting screw 12 is connected to a worm gear 13, and an adjusting handle 14 is installed at the end of the worm gear 13. When the height of the fixed magnet 3 needs to be adjusted, the adjusting handle 14 is rotated, and the adjusting screw 12 is driven to rotate by the transmission of the worm gear 13. The driving platform 11 threadedly connected to the adjusting screw 12 cannot rotate with the adjusting screw 12 due to the limitation of the positioning installation frame 10. The driving platform 11 can only drive the fixed magnet 3 to move up and down along the length direction of the adjusting screw 12. When the fixed magnet 3 is magnetically adsorbed to the bottom surface of the insulation box 2, the insulation box 2 is fixed. When the fixed magnet 3 is separated from the bottom surface of the insulation box 2, the insulation box 2 can be removed from the support platform, which is convenient for cleaning the inside of the insulation box 2.

[0042] The worm gear 13 has a self-locking function. When the adjustment handle 14 is not moved, the adjustment screw 12 remains stationary, and the fixed magnet 3 remains in its current position. This design can keep the fixed magnet 3 in the adjusted position, thereby stably achieving magnetic fixation and release of the fixed magnet 3 to the thermal insulation box 2.

[0043] Compared with the prior art, the present invention has at least the following beneficial effects:

[0044] The utility model utilizes a lifting adjustment part to change the distance between the fixed magnet and the insulation box, thereby realizing the magnetic adsorption adjustment of the fixed magnet to the insulation box, so that the installation, fixation and disassembly of the insulation box can be completed quickly, which is convenient for operators to quickly disassemble and assemble the insulation box, while ensuring the safety of the food delivery vehicle. It has the characteristics of simple structure and convenient operation.

[0045] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
