Abstract

The invention discloses a connecting device for a stair handrail. The connecting device comprises a plastic connecting body, wherein a handrail mounting hole is formed inside the plastic connecting body, a gap releasing groove is formed in one side of the handrail mounting hole, a semicircular and gradually-varied first boss is arranged on each of two sides of the plastic connecting body, and a self-centering second boss is further arranged on each of the two sides of the plastic connecting body. The connecting device for the stair handrail has the advantages that the plastic connecting body can rotate in a mounting groove by the aid of a rolling part and the expansion and retraction of the gap releasing groove are controlled by a fastener so as to control the change of the diameter of the handrail mounting hole, and accordingly the mounting and adjusting of the stair handrail are facilitated.

Description

technical field [0001] The invention relates to the field of home improvement applications, in particular to a connecting device for stair handrails, stair rungs and stair railings, which is applicable to the installation of stairs with different heights and angles. Background technique [0002] In the existing stair system, since the height and angle of each stair are different, a special adjustment device is required, and some of them need to be manufactured on site, so the installation of the stair handrail is more cumbersome and complicated. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention proposes a stair handrail connecting device to facilitate the installation and adjustment of the stair handrail. [0004] To achieve the above object, the technical scheme of the present invention is as follows: [0005] A stair handrail railing connecting device, including a connecting plastic part body, a railing pl...
