Description

technical field [0001] The invention relates to a stair guardrail structure, in particular to a stair guardrail handrail surface tube corner fitting and a stair guardrail handrail. Background technique [0002] The stair guardrails are equipped with elbow joints connecting the handrail surface pipes at the corners. Since the angles between the two stair guardrails of different stairs are different, the elbow joints of the handrail surface pipes need to have certain versatility in order to save production costs. The existing stair guardrails are usually provided with two butt joints at the corners of the handrail surface pipe, the two elbow joints are respectively connected with a section of the handrail surface pipe, and the butt ends of the two elbow joints are cylindrical or cylindrical Design, the two elbow joints can be rotated arbitrarily when they are docked, so that this elbow joint can be used in the installation of stair guardrails with different angles, and has str...
