Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to an integrated structure of a desk and bookcase. Background Technology

[0002] Traditional freestanding bookshelves are physically separated from desks, requiring users to move them frequently to access, read, and store books, resulting in low efficiency. Some simple modular furniture only achieves basic assembly without forming an organic whole, leading to low space utilization and inefficient use of the space under the desk and bookshelves. Moreover, the desktop width of existing integrated furniture is mostly fixed, making it unable to adapt to different usage scenarios.

[0003] In addition, some integrated furniture uses welding or multi-bolt fixing structures, which are more stable but difficult to disassemble and transport. Other products simplify the connection structure in pursuit of ease of disassembly and assembly, resulting in components such as pegboards and shelves not being installed securely, and they are prone to loosening and displacement after long-term use. Utility Model Content
