Description

Technical Field

[0001] The utility model relates to the technical field of turnover boxes, in particular to a heat-insulating mobile turnover box. Background Art

[0002] Turnover boxes, also known as logistics boxes, are mostly made of PP and HDPE as raw materials. They are non-toxic and odorless, UV-resistant, not easy to change color, have a smooth surface, are easy to clean, and have good thermal insulation effects, making them convenient for storing objects for mobile transportation.

[0003] The existing turnover boxes still have the following defects: 1. They are large in size, not convenient for storage and take up space; 2. They lack a positioning structure, which makes it easy for the boxes to fall down when they are stacked together and transported in bumpy conditions. To this end, we propose a heat-insulating mobile turnover box. Utility Model Content

[0007] Furthermore, the box cover is located on the top of the box body, and the box body, extension frame and box cover are all PP hollow boards; the PP hollow board has good thermal insulation properties to ensure the thermal insulation effect of the turnover box.

[0008] Furthermore, the bottoms of both sides of the box cover are connected with lock buckles through rotating shafts.

[0009] Furthermore, a limited frame is provided at the top of the extension frame corresponding to the position of the telescopic opening, and the positioning bolts are passed through the top of the two side surfaces of the box through reserved threaded holes, and one end of the positioning bolts is in contact with the extension frame.

[0010] Furthermore, the first clamping block, the second clamping block, the third clamping block and the fourth clamping block are all connected to the box cover via spring clips.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting the telescopic opening, the extension frame, the positioning bolts and the limiting frame, the telescopic opening is used to cooperate with the extension frame for lifting and lowering, and then the positioning bolts are rotated to squeeze the extension frame to fix it, and the limiting frame is used to be fixed to the telescopic opening for limiting when the extension frame is stored back into the inner cavity of the box, which is convenient for storage and use.

[0013] 2. By setting the first clamp block, the second clamp block, the third clamp block, the fourth clamp block and the spring clip, the turnover boxes stacked on the top are clamped and fixed in place by using the spring clip to cooperate with the corresponding first clamp block, the second clamp block, the third clamp block and the fourth clamp block, so as to avoid falling due to severe bumps during movement.
