AI Technical Summary
Technical Problem
The existing bed frame rods are unstable, prone to rotation causing abnormal noises, and difficult to disassemble and repair.
Method used
The design employs a combination of insertion through holes and fixed through holes. The diameter of the insertion through hole along the axial direction of the first rod is greater than or less than the vertical diameter. The insertion end matches the insertion through hole and is fixed axially by a fastener to prevent rotation.
Benefits of technology
It improves the stability of the rod connection, avoids abnormal noises during bed use, and simplifies the installation and disassembly process.

Abstract
A rod connection structure of a bed frame, comprising first rods and second rods that are perpendicular to each other, and fixing members, wherein the second rods are connected between the first rods located on two sides, the rod surface of each first rod facing towards a second rod is provided with an insertion through hole allowing for insertion of the second rod, the rod surface of each first rod facing away from a second rod is provided with a fixing through hole, and the area of the fixing through hole is smaller than that of the insertion through hole; the diameter of each insertion through hole in the axial direction of the corresponding first rod is greater than or less than the diameter in a direction perpendicular to the axial direction of the first rod; each end of each second rod is configured as an insertion end, the cross section of the insertion end is consistent with the insertion through hole in shape and size, and the length of each insertion end in the axial direction of the corresponding second rod is greater than the diameter of the corresponding first rod; the insertion end is in insertion fit with the insertion through hole; each fixing member passes through a fixing through hole and is limited by the rod surface where the fixing through hole is located; the end surface of each insertion end is provided with a connecting groove in the axial direction of the corresponding second rod, and a fixing member passes through the connecting groove and is detachably connected to the second rod.
