Technical Field

The invention relates to the field of handrails, in particular to a handrail quick-connection elbow.

Background

The stair railing is a support rod of a stair guardrail. Stair handrails are classified by material: stair macromolecule handrail, stair iron art handrail, stair stainless steel handrail, stair glass handrail, stair solid wood handrail and stair copper handrail. Present handrail all needs the fixed mounting elbow when stair corner installation, and the elbow mainly plays linking up two effects that are certain angle handrail, and the elbow of traditional stair handrail generally all needs the bracing piece through the bottom to come the fixed stay, and the elbow is connected with the handrail through screw or riveted form with the handrail mainly in addition, and the elbow installation is inconvenient, and the cost of installation is also than higher moreover.

In addition, chinese patent publication No. CN202882258U discloses a handrail elbow, which comprises a pipe body, wherein a first port and a second port are arranged at two ends of the pipe body, the diameter of the cross section of the first port is larger than that of the cross section of the pipe body, and the diameter of the cross section of the second port is smaller than that of the cross section of the pipe body. Although the handrail elbow has the function of quickly connecting the handrail, the center lines of the first port and the second port of the pipe body of the elbow are located on the same plane, the handrail elbow is only suitable for quickly connecting the handrail on the horizontal plane and is not suitable for quickly connecting the handrail corner with the slope, and the meshing force of the handrail elbow and the fast connecting position of the handrail elbow is not enough, so that the handrail elbow is easy to shake due to the existence of a splicing gap.
