Guard railing used for windows with extending and contracting functions

Abstract

The invention discloses a guard railing used for windows with an extending and a contracting functions. The guard railing comprises an upper concave groove beam, a lower concave groove beam and a longitudinal stand column, wherein the lengthways stand column is arranged between the upper concave groove beam and the lower concave groove beam, horizontal pipes are connected with both an open end of the upper concave groove beam and an open end of the lower concave groove beam, the lengthways stand column comprises an outer casing pipe and a telescopic pipe, wherein the outer casing pipe is arranged on the top of the lower concave groove beam and extends upward, one end of the telescopic pipe is arranged at the bottom of the upper concave groove beam and the other end of the telescopic pipe is arranged inside the outer casing pipe in a sleeved mode and moves up and down along the outer casing pipe, the outer sides of the horizontal pipes are provided with radial casing pipes which point toward the stand column, and radial telescopic pipes are arranged on inner side walls of the upper concave groove beam and the lower concave groove beam. The guard railing used for windows with the extending and contracting function can stretch to the space between Y axial direction and Z axial direction so that a user can regulate the railing according to external dimensional requirement the window by himself or herself, thus improving universality of the guard railing, lowering non-standard characteristic of the manufacturing of the guard railing and thoroughly changing the traditional processing method of 'one window with one measurement'.

Description

technical field [0001] The invention relates to a protective fence, in particular to a window protective fence with telescopic function. Background technique [0002] Protective fence (Protective fence)-here is an industrial "protective fence" or crash fence, which is mainly used for the protection and protection of equipment and facilities in factories, workshops and warehouses. It is usually made of steel, such as round steel pipe, square steel pipe or profiled steel plate. Surface treatment process: automatic electrostatic powder spraying (that is, plastic spraying) or painting. The raw materials used for the surface treatment of outdoor crash barriers are waterproof materials. The anti-collision guardrail has a beautiful appearance and is not easy to rust. [0003] The window guardrail is an application channel of the guardrail. The window guardrails in the prior art are all non-standard rooms. Every time they are processed and manufactured, the manufacturer needs to ...

Problems solved by technology

[0003] The window guardrail is an application channel of the guardrail. The window guardrails in the prior art are all non-standard rooms. Every time they are processed and manufactured, the manufacturer needs to go to the site to measure and then process. The disadvantages of this production method There are many, one is that the processing workload is heavy, and the other is that non-standard guardrails cannot be made into stock, which often leads to unsatisfactory productivity or tight production, and cannot produce normally
