Description

Technical Field

[0001] This utility model relates to the field of insulated boxes, and in particular to a foldable insulated box for transporting meals. Background Technology

[0002] Insulated food transport boxes are containers specifically designed to maintain food at a suitable temperature during transportation. Made with high-efficiency insulation materials such as polyurethane foam, they effectively insulate against external temperature influences, slowing heat loss from the food and preventing external heat intrusion. Their excellent sealing prevents heat loss through gaps. The rationally designed internal space can accommodate various sizes of food containers. In scenarios such as food delivery and group meal distribution, insulated food transport boxes play a crucial role in ensuring that food remains at the appropriate temperature and taste upon delivery.

[0003] However, most existing insulated food transport boxes are fixed structures, taking up a lot of space and making them inconvenient to store and carry, as well as difficult to store after transportation. In addition, some foldable insulated boxes are not stable after folding and are prone to falling apart during movement or storage, affecting the user experience. They cannot simultaneously meet the needs of easy folding and stability after folding, and have certain drawbacks in use.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides a foldable food transport insulated box, which has the effect of ensuring stability after folding. It can not only meet the insulation requirements during transportation, but also is not easy to unfold when folded, greatly improving the convenience and stability of carrying and using.

[0006] The technical solution adopted by this utility model is as follows: it includes an upper frame and a lower frame, on which the outer elastic insulation layer and the inner elastic insulation layer are fixedly installed. The upper frame and the lower frame are connected to each other through a rotating inward folding assembly. The rotating inward folding assembly is divided into two symmetrically distributed groups. The first pin positioning assembly and the second pin positioning assembly are respectively installed on the two groups of rotating inward folding assemblies. When the first pin positioning assembly and the second pin positioning assembly are horizontal, they are fixedly connected to each other.

[0007] Preferably, in order to seal the entire insulated box through the insulated top cover, the insulated top cover is rotatably mounted on the upper frame.

[0008] Preferably, in order to enable the upper vertical block and the lower vertical block to rotate on the upper frame and the lower frame via the first hinge and the second hinge, the rotating inward folding assembly includes the upper vertical block and the lower vertical block. The upper vertical block is rotatably connected to the upper frame via the first hinge, and the lower vertical block is rotatably connected to the lower frame via the second hinge.

[0009] Preferably, in order to enable the upper vertical block and the lower vertical block to rotate and fold through the third hinge, the upper vertical block and the lower vertical block are rotatably connected through the third hinge.

[0010] Preferably, in order to enable the first fixed threaded sleeve and the first positioning head to rotate with the upper vertical block and the lower vertical block, the first pin positioning assembly includes the first fixed threaded sleeve and the first positioning head, which are respectively fixed to the inner wall of the upper vertical block and the lower vertical block on one side.

[0011] Preferably, in order to fix the upper vertical block and the lower vertical block together by means of the internal threaded connecting sleeve, the first fixed threaded sleeve is rotatably threadedly inserted into the first push screw, one end of the first push screw is fixedly installed with the first screw head, the other end of the first push screw is fixedly installed with the internal threaded connecting sleeve, and the internal threaded connecting sleeve is inserted into the pin hole opened in the first positioning head.

[0012] Preferably, in order to enable the second fixed threaded sleeve and the second positioning head to rotate with the upper vertical block and the lower vertical block, the second pin positioning assembly includes the second fixed threaded sleeve and the second positioning head, which are respectively fixed to the inner walls of the upper vertical block and the lower vertical block on the other side.

[0013] Preferably, in order to fix the folded insulation box by connecting the threaded connecting head and the internal threaded connecting sleeve, the second fixing threaded sleeve is rotatably threadedly inserted into the second push screw. One end of the second push screw is fixedly installed with the second screw head, and the other end of the second push screw is fixedly installed with the threaded connecting head. The threaded connecting head is inserted into the pin hole opened on the second positioning head, and the threaded connecting head and the internal threaded connecting sleeve are correspondingly adapted in a horizontal state.

[0014] The beneficial effects of this utility model are: the upper frame and the lower frame are folded by the rotating inward folding component, which is convenient to operate; after folding, the horizontal first pin positioning component and the second pin positioning component are fixedly connected to each other, which ensures the stability after folding. It can not only meet the heat preservation requirements during transportation, but also prevent it from unfolding when folded for storage, which greatly improves the convenience and stability of carrying and using.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1-5As shown, this embodiment provides a foldable insulated food transport box, including an upper frame 1 and a lower frame 2. An outer elastic insulation layer 3 and an inner elastic insulation layer 4 are fixedly installed on the upper frame 1 and the lower frame 2. The upper frame 1 and the lower frame 2 are connected to each other by a rotating inward folding assembly 5. The rotating inward folding assembly 5 is divided into two symmetrically distributed groups. A first pin positioning assembly 6 and a second pin positioning assembly 7 are respectively installed on the two groups of rotating inward folding assemblies 5. When the first pin positioning assembly 6 and the second pin positioning assembly 7 are horizontal, they are fixedly connected to each other. An insulated top cover 8 is rotatably installed on the upper frame 1. When in use, the insulated top cover 8 is opened and the food is put into the box. When transportation is completed and no longer needed, the positioning of the rotating inward folding components 5 on both sides is released by controlling the first pin positioning component 6 and the second pin positioning component 7. The upper frame 1 and the lower frame 2 are folded by the rotating inward folding components 5. When the first pin positioning component 6 and the second pin positioning component 7 on the two sets of rotating inward folding components 5 are in a horizontal position, the two are fixedly connected. Finally, the heat-insulating top cover 8 is closed to complete the storage, which is convenient for folding and ensures the stability after folding.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 3 As shown, the rotating inward folding assembly 5 includes an upper vertical strip 501 and a lower vertical strip 502. The upper vertical strip 501 is rotatably connected to the upper frame 1 via a first hinge 503, and the lower vertical strip 502 is rotatably connected to the lower frame 2 via a second hinge 504. The upper vertical strip 501 and the lower vertical strip 502 are rotatably connected to each other via a third hinge 505. When using this insulated box, the upper vertical strip 501 and the lower vertical strip 502 support the box in the unfolded state. When folding is required, the first hinge 503 and the second hinge 504 are used to rotate the upper vertical strip 501 and the lower vertical strip 502 relative to the upper frame 1 and the lower frame 2, and then the third hinge 505 allows the upper vertical strip 501 and the lower vertical strip 502 to fold together, completing the box folding. The operation is simple and can achieve effective folding.

[0024] As a technical optimization solution of this utility model, specifically as follows: Figures 3-5As shown, the first pin positioning assembly 6 includes a first fixed threaded sleeve 601 and a first positioning head 602. The first fixed threaded sleeve 601 and the first positioning head 602 are respectively fixed on the inner walls of the upper vertical strip 501 and the lower vertical strip 502 on one side. The first fixed threaded sleeve 601 is rotatably threaded into a first push screw 603. A first screw head 604 is fixedly installed at one end of the first push screw 603, and an internal threaded connecting sleeve 605 is fixedly installed at the other end of the first push screw 603. The internal threaded connecting sleeve 605 is inserted into a pin hole opened on the first positioning head 602. The second pin positioning assembly 7 includes a second fixed threaded sleeve 701 and a second positioning head 702. The second fixed threaded sleeve 701 and the second positioning head 702 are respectively fixed to the inner walls of the upper vertical strip 501 and the lower vertical strip 502 on the other side. The second fixed threaded sleeve 701 is rotatably threaded into a second push screw 703. A second screw head 704 is fixedly installed at one end of the second push screw 703, and a threaded connecting post 705 is fixedly installed at the other end of the second push screw 703. The threaded connecting post 705 is inserted into a pin hole opened on the second positioning head 702. The threaded connecting post 705 and the internal threaded connecting sleeve 605 are correspondingly adapted in the horizontal state. When using the insulation box, in the unfolded state, the internal threaded connecting sleeve 605 of the first pin positioning assembly 6 is inserted into the pin hole of the first positioning head 602, and the threaded connecting post 705 of the second pin positioning assembly 7 is inserted into the pin hole of the second positioning head 702 to achieve positioning. When folding, rotate the first screw head 604 and the second screw head 704 to move the first push screw 603 and the second push screw 703, disengage the plug, and after folding, allow the threaded connection post 705 to be horizontally fitted and connected with the internal threaded connection sleeve 605 to complete the fixation.
