Description

Technical Field

[0001] The utility model relates to the technical field of pallets, in particular to an injection-molded pallet. Background Art

[0002] Test tubes are commonly used instruments in chemical laboratories. Since most of them are made of glass, they are easily damaged if they encounter collisions during transportation. Therefore, they need to be protected and transported using pallets. Existing pallets often vertically insert the lower end of the test tube into a fixing hole, and the other end of the test tube extends out of the fixing hole. Since the test tube has a certain length, the test tube may fall out of the fixing hole during transportation, thereby affecting the transportation of the test tube.

[0003] For example, the patent number CN216727367U discloses a simple dual-purpose test tube tray, including a tray body, on which a plurality of test tube fixing holes are provided; the test tube fixing holes include a cylindrical hole section and a conical hole section; the cylindrical hole section is provided at the top of the tray body, and is used to fix round-bottom test tubes, and the shape of the cylindrical hole section is adapted to the bottom of the round-bottom test tube to be fixed, and the conical hole section is provided at the bottom of the cylindrical hole section, and is used to fix pointed-bottom test tubes. Although the test tube tray can be used for both round-bottom test tubes and pointed-bottom test tubes, in actual use, the lower end of the test tube is vertically inserted into the fixing hole, and the other end of the test tube extends out of the fixing hole, and the test tube is easily dislodged from the fixing hole during transportation, thereby affecting the transportation of the test tube.
