Description

Technical Field

[0001] The utility model belongs to the field of installation structures of handrails, and in particular relates to an installation structure of a handrail. Background Art

[0002] Stair handrails are a type of stair guardrail. Stair handrails are usually installed at both ends of the stairs to prevent pedestrians from falling down the stairs or to help pedestrians climb up. Stair handrails are usually composed of multiple vertical longitudinal bars and multiple inclined horizontal bars. When installing stair handrails, you need to first fix the longitudinal bars to the stairs, and then install and fix the horizontal bars to the longitudinal bars.

[0003] The Chinese patent with publication number CN209323849U discloses a stair handrail installation structure, which includes two columns installed on the top and the lower step of the stairs, and also includes a plurality of handrail assemblies installed between the two columns, each handrail assembly includes a vertical rod and a horizontal rod arranged at both ends of the vertical rod, one end of the horizontal rod is provided with a mounting groove, and the other end is provided with a mounting block, and two adjacent handrail assemblies are formed by the clamping of the mounting block and the mounting groove. The utility model realizes the detachable connection between the handrail assemblies by arranging the mounting block and the mounting groove on the horizontal rod, so that the undamaged handrail can still be used, which is beneficial to saving materials. However, in the stair handrail installation structure of the application, after the handrail in the handrail assembly is elastically positioned by the insertion rod, the adjacent two handrail assemblies need to be positioned again, and the positioning efficiency is slow, and the insertion rod handle is exposed on the side of the handrail assembly, which affects the user's experience.

[0004] In view of this, the present utility model is proposed. Utility Model Content
