[0002] Government agencies, schools, factories, mines, and other enterprises and institutions have canteens to provide meals for their internal staff and students. In special circumstances, these canteens need to deliver food to external locations to ensure the meals of those working outside the premises. Delivery boxes are frequently used tools for this purpose. Existing delivery boxes include simple and convenient baskets, or boxes made of plastic, foam, or metal, which ensure the cleanliness of the food during delivery. However, existing delivery boxes cannot guarantee that the food and drinks will maintain their original temperature upon arrival at the diners, thus affecting the taste and the quality of the meal. Furthermore, existing delivery boxes are not stable during transport, easily leading to spills. Utility Model Content

[0003] The purpose of this utility model is to provide a food delivery box with both cold and heat preservation functions. The food delivery box has both cold and heat preservation functions. When hot food and / or cold food is transported out through the food delivery box, the food can be kept warm or / or kept cold, so that the transported food maintains its original temperature and ensures the taste of the transported food. At the same time, through the shock absorption mechanism and the adjustment mechanism, the problem of bumps caused by uneven road surfaces during the displacement process is solved. Once a large amount of bumps occurs, the food inside the box may tip over or shift due to the indirect force.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0017] 2. This utility model incorporates springs. When the food delivery box experiences bumps during movement, the box vibrates up and down and shifts. This causes the upper guard plate to shift, which in turn causes several sliding rods and axle seats to shift. During this process, the upper guard plate occasionally compresses several springs, and each axle seat causes the connecting rod to shift and rotate. The connecting rod then causes the displacement axle seats to shift, and the displacement axle seats transmit the impact force to the springs. This design effectively buffers and reduces vibrations when the food delivery box experiences significant bumps on uneven surfaces during its movement.

[0018] 3. This utility model incorporates a solar panel. Rotating the handle drives the worm gear, which in turn drives the worm wheel, which in turn drives the fixed base. The fixed base then causes the solar panel to flip left and right to change its tilt angle. To adjust the front and rear tilt angle of the solar panel, the handle can be rotated, which in turn drives the worm gear, which in turn drives the connecting rod. This allows the tilt angle of the solar panel to be freely adjusted according to changes in the angle of sunlight, ensuring that the solar panel receives sufficient sunlight to convert it into electricity for cooling and insulation.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] One specific application of this embodiment is:

[0036] When staff need to use the food delivery box, they can move it freely by pushing the handle 103 and using several casters 212. If the food delivery box experiences bumps during movement, the box body 1 will vibrate up and down and shift. The box body 1 will cause the upper guard plate 201 to shift, which in turn will cause several sliding rods 202 and several bearing seats 210 to shift. During this process, the upper guard plate 201 will occasionally compress several springs 203, and several bearing seats 210 will cause the connecting rod 209 to shift and rotate. The connecting rod 209 will then cause the displacement bearing seats 208 to shift, and the several displacement bearing seats 208 will be subjected to... The impact force is transmitted to spring 211. Several springs 203 and spring 211 will fully buffer the impact force received by the box 1 to prevent the food placed inside the box 1 from tipping over or shifting. The insert plate 107 will divide the internal space of the box 1 into two parts. The door 102 can be opened upwards to put food into the box 1. When it is necessary to remove the insert plate 107, simply grab the insert plate 107 and pull it upwards to detach it from the insert plate slot 106. The space exposed by the refrigeration module 104 is used to place food that needs to be refrigerated, and the space exposed by the insulation module 105 is used to place food that needs to be kept warm. Solar panel 310 converts received light energy into electrical energy and supplies it to insulation module 105 and cooling module 104. Cooling module 104, once powered on, cools the space it occupies, while insulation module 105, once powered on, provides the necessary heat for insulation. The cooling temperature of cooling module 104 and the insulation temperature of insulation module 105 can be adjusted using controller 101. To adjust the angle of solar panel 310 according to the angle of sunlight, throttle 303 can be turned. Throttle 303 drives worm gear 302, which in turn drives worm wheel 308, which in turn drives... When the fixed seat 309 rotates, it causes the solar panel 310 to flip left and right to change its tilt angle. To adjust the front and back tilt angle of the solar panel 310, the second throttle 313 can be rotated. The second throttle 313 will cause the second worm gear 312 to rotate, which in turn will cause the worm wheel 306 to rotate. The worm wheel 306 will cause the connecting rod 305 to rotate, which will in turn cause the flipping frame 307 to rotate. The flipping frame 307 will cause the second worm wheel 308 to rotate around the worm gear 302, which will then cause the fixed seat 309 to rotate. The fixed seat 309 will then flip to change its tilt angle.
