Description

Technical Field

[0001] This utility model relates to the field of nursery bed equipment technology, and in particular to a nursery bed board assembly that is easy to assemble and disassemble. Background Technology

[0002] The nursery bed described in this article is specialized equipment for piglet rearing. Typically, a fence surrounds the nursery bed. Several crossbeams 2 are installed under the nursery bed, and several nursery bed panels 1 are fixed to the crossbeams 2 using bolts. Since the piglets are placed on the nursery bed panels 1, they experience vibration and impact. To ensure reliable support, the bolts fixing the nursery bed panels 1 are locked together. Therefore, disassembly is difficult later on. For example, if cleaning and disinfection of the back of the nursery bed panels 1 is required, or if the nursery bed needs to be moved, it must be disassembled and reassembled.

[0003] Therefore, there is an urgent need to propose a nursery bed board that is simple in structure, easy to assemble and disassemble, and has reliable connections. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a nursery bed board assembly that is easy to assemble and disassemble. The technical solution adopted by this utility model is as follows:
