Guardrail rotary joint assembly and guardrail

Abstract

The invention discloses a guardrail rotary joint assembly and a guardrail. The rotary joint assembly includes a joint body rotating through taking a fixed pipe near a movable part in the guardrail as a center shaft; the joint body is provided with a fixed pipe connecting part used for being connected with a fixed pipe, and a movable beam connecting part used for being connected with a movable beam in the guardrail. The guardrail includes the movable beam at the movable part as well as the fixed pipe at the fixed part; and the movable beam is connected with the fixed pipe near to the movable part through the guardrail rotary joint assembly. The guardrail rotary joint assembly and the guardrail both provided by the invention have the advantages of simple structure, low cost, convenience and fastness in installation, high bonding strength, and long service life.

Description

technical field [0001] The invention relates to assembly fittings connected by pipes, in particular to a rotary joint component and a guardrail used for a guardrail. Background technique [0002] Guardrail is a common pipe connection product. It is generally composed of beams and cylindrical vertical pipes. Among them, multiple horizontal beams are arranged at intervals up and down, and multiple vertical pipes are inserted in the beams at intervals along the vertical direction, and are connected with the beams. Connect to form a whole guardrail. [0003] In practical applications, guardrails usually need to have the function of rotating and opening. For example, there is a guardrail composed of a fixed part and a movable part. The fixed part is installed and fixed, and the movable part is connected to the fixed part through a hinge. It can be rotated relative to the fixed part to realize the function of opening or closing. The fixed part and the movable part of this kind o...

AI Technical Summary

Problems solved by technology

The fixed part and the movable part of this kind of guardrail are both separate integral structures, wherein the fixed part is connected by fixed beams and fixed tubes to form a whole with a frame, and the movable part is connected by a movable beam and a movable tube to form a whole with a frame. As a whole, the frames of the two are connected by hinges, which leads to the fact that two frames must be arranged side by side at the junction of the fixed part and the movable part of the guardrail, resulting in an increase in the amount of consumables for the frame, which increases the production cost and increases the difficulty of production; the movable part After rotating and opening, only the hinge is connected to the fixed part and bears the load. The shear force of the movable part's own weight on the hinge is likely to cause deformation and damage to the hinge, resulting in problems such as the guardrail cannot be closed or closed in place.

In addition, the hinge is used to connect the fixed part and the movable part, which is inconvenient to install, the overall strength of the guardrail after installation is not high, and the safety and service life of the guardrail are also low
