Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a portable double-folding box structure. Background Technology

[0002] In applications of portable instruments and equipment in fields such as biology, medicine, chemistry, and water quality testing, especially in outdoor testing environments, higher requirements are placed on the portability, ease of operation, and protective performance of the instruments. Traditional cabinet structures are usually fixed or have a single opening design, requiring the entire cabinet to be opened or even completely disassembled before operation can be performed.

[0003] The shortcomings of existing technology:

[0004] 1. Simple structure and poor flexibility

[0005] Most existing cabinet structures adopt a single door or flip-top design, which cannot achieve folding and unfolding in multiple directions, thus limiting the user's operational needs in different environments.

[0006] 2. Low space utilization

[0007] Traditional enclosures take up a lot of space when opened, which is not conducive to use in confined or outdoor environments, and the layout of the operating area is unreasonable, affecting experimental efficiency.

[0008] 3. Lacks shading protection function

[0009] For certain light-sensitive testing tasks, existing enclosures cannot provide a good light-shielding environment, affecting the accuracy of the test results.

[0010] 4. The cable layout is messy and poses a significant safety hazard.

[0011] The exposed cables connecting components such as the display screen to the enclosure not only affect the overall appearance but also pose safety hazards such as cable tangling and breakage.

[0012] 5. The operation is complex and not suitable for non-professionals.

[0013] The operation requires disassembling multiple parts of the box, which is cumbersome, increases the barrier to entry, and reduces portability and practicality.

[0014] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content
