Description

Technical Field

[0001] This utility model relates to the field of shopping box technology, and more specifically, to a shopping box with heat preservation function. Background Technology

[0002] Shopping boxes are commonly used in daily life, widely applied in scenarios such as supermarket shopping, outdoor picnics, and short trips. With their large storage capacity and convenient mobility, they provide users with efficient solutions for loading and transporting goods, greatly facilitating people's daily lives and material handling needs.

[0003] However, existing shopping boxes have many shortcomings in actual use. On the one hand, since most shopping boxes need to be tilted when pulled, the items inside are prone to spillage when tilted, especially when carrying liquids or granular items, causing inconvenience to users. On the other hand, traditional shopping boxes are mostly made of single-layer plastic material, which has poor insulation performance and cannot effectively maintain the temperature of the items inside. When buying frozen foods, ice cream and other chilled items, or hot drinks, cooked food and other hot items, cold items are prone to melting and hot items are prone to cooling down, which fails to meet users' needs for maintaining the temperature of the items and limits the usage scenarios and practicality of shopping boxes.

[0029] Please see Figures 1-6 A shopping box with heat preservation function includes a shopping box body 1, characterized in that: a telescopic pull rod 2 is provided on the left side of the shopping box body 1, universal wheels 3 are provided on the lower surface of the shopping box body 1, a small storage cavity 4 is detachably connected to a storage box 5, four storage boxes 5 are provided and distributed at the four corners of the inner side wall of the shopping box body 1, three egg racks 7 are provided and evenly distributed from top to bottom, several round holes 8 are provided and evenly distributed in a rectangular array, a rubber gasket 25 is snapped into the inner side wall of the round holes 8, a handle 6 is provided on the outer surface of the storage box 5, an egg rack 7 is detachably connected to the inner side wall of the handle 6, a round hole 8 is provided on the upper surface of the egg rack 7, an arc-shaped limiting shell 9 is slidably connected to the inner side wall of the shopping box body 1 via a slide rail 10, and one end of the slider 19 on the outer surface of the arc-shaped limiting shell 9 is fixedly connected to a first Spring 11, one end of the first spring 11 abuts against the inner wall of the shopping box body 1. The inner wall of the arc-shaped limiting shell 9 is rotatably connected to the anti-spillage storage compartment 12. The front of the arc-shaped limiting shell 9 is fixedly connected to the end cap 13. The inner wall of the end cap 13 is slidably connected to the limiting telescopic rod 14. The outer surface of the limiting telescopic rod 14 is fixedly connected to the front of the end cap 13 with a knob 15. The lower end of the limiting telescopic rod 14 is fixedly connected to the second spring 16. The lower end of the second spring 16 is fixedly connected to the inner bottom wall of the end cap 13. The front of the end cap 13 is rotatably connected to the adjustment knob 17. The outer surface of the adjustment knob 17 is fixedly connected to the inside of the end cap 13 with a cam 18. The inner wall of the end cap 13 is slidably connected to the slider 19. One end of the slider 19 is fixedly connected to the third spring 20. One end of the third spring 20 is movably connected to the steel ball 21.

[0030] Specifically, through the arrangement of the toggle switch 15, the limiting telescopic rod 14, the second spring 16, and the first spring 11, when the toggle switch 15 is turned, the limiting telescopic rod 14 can be retracted, causing the limiting telescopic rod 14 to disengage from the inner wall of the shopping box body 1. At this time, the first spring 11, due to its elasticity, pops out the arc-shaped limiting shell 9, making it easy to open the spill-proof storage compartment 12 to place items. Through the arrangement of the arc-shaped limiting shell 9, the slide rail 10, and the spill-proof storage compartment 12, when the shopping box body 1 is tilted, the spill-proof storage compartment 12 can rotate freely inside the arc-shaped limiting shell 9. At the same time, the arc-shaped limiting shell 9 is connected to the inner wall of the shopping box body 1 by the slide rail 16. The shopping box body 1 is slidably connected, ensuring the smooth rotation of the spill-proof storage compartment 12. This allows the items inside to remain upright as much as possible when the shopping box is tilted, preventing spillage. By adjusting the knob 17, cam 18, slider 19, third spring 20, and steel ball 21, when the adjustment knob 17 is turned, the cam 18 rotates and pushes the slider 19. The slider 19 compresses the third spring 20, changing the contact pressure of the steel ball 21 against the inner wall of the spill-proof storage compartment 12. This allows adjustment of the rotation sensitivity of the spill-proof storage compartment 12 to adapt to different usage scenarios and better prevent spillage.

[0031] Please see Figure 1 , Figure 7 and Figure 8 The inner wall of the shopping box body 1 is provided with an insulation cavity 22 located outside the small storage cavity 4. There are two insulation cavities 22, which are symmetrically arranged on both sides of the inside of the shopping box body 1. There are two drain outlets 24, which are symmetrically arranged on the lower side of the outer surface of the shopping box body 1. The outer surface of the drain outlet 24 is threaded with a sealing cap. The outer surface of the shopping box body 1 is rotatably connected to the upper side of the insulation cavity 22. The lower outer surface of the shopping box body 1 is provided with a drain outlet 24.

[0032] Specifically, through the design of the insulation cavity 22, the top cover 23, and the drain outlet 24, when ice, ice water, or hot water is placed in the insulation cavity 22, the top cover 23 is closed to reduce heat loss. The hollow structure of the insulation cavity 22 reduces the heat transfer rate, thus cooling, warming, or heating the items in the storage box 5. After use, the water in the insulation cavity 22 can be easily drained by unscrewing the sealing cap of the drain outlet. By symmetrically arranging the insulation cavities 22 on both sides of the shopping box body 1 and correspondingly arranging the storage boxes 5 inside the insulation cavities 22, when ice or ice water is placed in the left insulation cavity 22, the items in the two left storage boxes 5 can be cooled and kept fresh. When hot water is poured into the right insulation cavity 22, the items in the two right storage boxes 5 can be warmed and heated, meeting the different temperature requirements of different items.

[0033] In summary, when using the entire device: it is moved by pulling the telescopic rod 2 and the universal wheels 3. For storage, the knob 15 can be turned downwards, causing the limiting telescopic rod 14 to retract. The upper end of the limiting telescopic rod 14 disengages from the inner wall of the shopping box body 1. At this time, the first spring 11 ejects the arc-shaped limiting shell 9 outwards. Items prone to spillage can then be placed inside the spill-proof storage compartment 12. After closing the spill-proof storage compartment 12, when pulled, the left side of the shopping box body 1 rises and tilts to the right. The spill-proof storage compartment 12 can then rotate freely inside the arc-shaped limiting shell 9, compensating for the tilt angle. Adjusting the knob 17 to rotate the cam 18 adjusts the pressure applied to the steel ball 21 by the slider 19 via the third spring 20. The steel ball 21 then exerts pressure on the spill-proof storage compartment 12. The tighter the inner wall abuts, the greater the damping, which in turn adjusts the sensitivity of the rotation of the spill-proof storage compartment 12, improving its practicality. Smaller items can be placed inside multiple storage boxes 5, and one of the storage boxes 5 has a detachable egg rack 7 inside, which can hold eggs inside the rubber gasket 25, further improving the device's practicality. When it is necessary to store hot or cold items, the left top cover 23 can be opened as needed to inject cold water inside. Similarly, the right top cover 23 can be opened to inject hot water, thereby effectively improving the device's heat preservation performance. After use, the cold and hot water can be drained by opening the corresponding drain outlets 24. Even when there is no cold or hot water, the heat preservation cavity 22 forms a hollow structure, which can effectively reduce heat transfer efficiency, thereby improving heat preservation performance.

[0034] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
