Abstract

The utility model relates to a safe water downpipe, the body of which is composed of a plane pipe wall and a main pipe wall integrated with the plane pipe wall into a whole. The utility model is characterized in that a plurality of convex ribs are made on the main pipe wall along the length direction, the cross-section of the convex rib is in an arc shape, and the pipe is made of aluminum alloy. After the installation of the utility model, the plane pipe wall clings closely to the wall surface, which is hard for thieves to climb, so the stolen possibility of residents living upstairs can be reduced, and the residents' sense of security can be enhanced. The convex ribs on the pipe surface enhance the strength of the pipe which can be made of aluminum alloy. Without anchor ears needed in the installation, the pipe has a more beautiful appearance.

Description

Safe leader

Affiliated technical field

The utility model relates to a kind of leader that is fixed on the skin.

Background technology

The at present general leader that is fixed on the skin is generally circular galvanized sheet iron pipe, and installs by anchor ear, owing to be easy to climbing, causes unsafe factor to resident family.Be difficult for climbing though the patent No. is the antitheft gutter of ZL02239063.4, it only is fit to make of plastic material, and is easily aging, intensity difference.

Summary of the invention

The purpose of this utility model provides a kind of difficult climbing and high leader of intensity that is fixed on the skin.

Its body of the utility model safety leader constitutes by the plane tube wall with person in charge's wall that the plane tube wall is made as one, and its design feature is to be manufactured with some convex tendons along its length being responsible on the wall, and the cross sectional shape of this convex tendon is an arc.

Safe as mentioned above leader, its body is made by aluminum alloy materials.

Safe as mentioned above leader, its cross sectional shape of being responsible for wall can be semicircle, ∪ shape or trapezoidal.

Safe as mentioned above leader, being responsible for the wall both sides has the flange that is stretched out and formed by the plane tube wall.

The utility model is installed the back plane tube wall and is close to metope, and the burglar is difficult to climbing, has reduced the stolen possibility of resident family upstairs, has strengthened Citizens'Sense of Security.Because the surface has convex tendon, improved intensity, can adopt aluminum alloy materials to make, and when installing without anchor ear, seem more elegant in appearance.

The specific embodiment

Embodiment illustrated in fig. 1, body constitutes by the plane tube wall 1 that is adjacent to metope after installing with person in charge's wall 2 that plane tube wall 1 is made as one, the cross sectional shape of being responsible for wall 2 is a U-shaped, is manufactured with the convex tendon 3 that some cross sectional shapes are arc along its length on person in charge's wall 2.

Embodiment illustrated in fig. 2, the cross sectional shape of being responsible for wall 2 is semicircle, is manufactured with the convex tendon 3 that some cross sectional shapes are arc along its length on person in charge's wall 2, and being responsible for wall 2 both sides has the flange 4 that is stretched out and formed by plane tube wall 1, so that install.

Embodiment illustrated in fig. 3, the cross sectional shape of being responsible for wall 2 is trapezoidal, is responsible on the wall 2 and is manufactured with the convex tendon 3 that some cross sectional shapes are arc along its length, and being responsible for wall 2 both sides has the flange 4 that is stretched out and formed by plane tube wall 1.

Body of the present utility model is by by an extrusion modling of aluminum alloy materials.
