CN201208153Y - Improved steel plastic composite curtain rod - Google Patents

Abstract

The utility model discloses an improved structure of a curtain rod compounded by plastic-steel. The improved structure comprises a rod body which comprises a three-layer structure, that is, an outer layer is an external plastic piece, a middle layer is a metal pipe, and an inner layer is an internal plastic piece. Since the inner surface of the metal pipe does not contact with the outside so as to effectively solve the problem of rustiness oroxidation on the inner surface of the metal pipe; and the structure of the internal plastic piece causes the decreasing usage amount of metal materials under the condition of ensuring an original strength, the utility model overcomes the defects of the prior compound plastic-steel curtain. And the utility model has the advantages of ensuring the service life and the attractive appearance of the curtain rod.

Description

A kind of structure-improved of steel-plastics composite window curtain rod

Technical field

The utility model relates to a kind of curtain rod, particularly a kind of structure-improved of steel-plastics composite window curtain rod.

Background technology

The applicant once applied for a kind of steel-plastics composite window curtain rod patent, its publication number is CN2917476, this structure mainly is made up of the body of rod, the body of rod is divided into inside and outside two-layer, internal layer is a metal tube, and skin is outer plastic, and the outer surface of its China and foreign countries' plastic is provided with twice and increases sliding muscle.Through use finding, because of the inner surface of inner layer metal pipe directly contacts with air, be easy to take place oxidation or get rusty, have a strong impact on service life of curtain rod and attractive in appearance.Moreover along with rising steadily of international raw metal, the metal that internal layer uses constantly rises product cost.

The utility model content

The purpose of this utility model is to provide a kind of structure-improved of steel-plastics composite window curtain rod, and it can effectively solve getting rusty or problem of oxidation of metal pipe internal surface, reduces the use amount of raw metal simultaneously under the situation that guarantees original intensity, reduces production costs.

For achieving the above object, the utility model is by the following technical solutions:

A kind of structure-improved of steel-plastics composite window curtain rod comprises a body of rod, it is characterized in that: the described body of rod is divided into three-decker, and skin is outer plastic, and the middle level is a metal tube, and internal layer is interior plastic.

Metal pipe internal surface of the present utility model does not directly contact with the external world, can effectively solve getting rusty or problem of oxidation of metal pipe internal surface, has guaranteed service life of curtain rod and attractive in appearance.Because of interior plastic component structure, the use amount that can reduce raw metal under the situation that guarantees original intensity that makes reduces production costs simultaneously.

The specific embodiment

As illustrated in fig. 1 and 2, a kind of structure-improved of steel-plastics composite window curtain rod comprises a body of rod 1, and the body of rod 1 is divided into three-decker, and skin is outer plastic 11, and the middle level is a metal tube 12, and internal layer is interior plastic 13, and the three extrudes by heat seal and is composited.

Metal tube 12 inner surfaces of the present utility model directly do not contact with the external world, can effectively solve getting rusty or problem of oxidation of metal pipe internal surface, have guaranteed service life of curtain rod and attractive in appearance.Because of interior plastic 13 structures, the use amount that reduces raw metal under the situation that guarantees the original intensity of the body of rod that makes reduces production costs simultaneously.

Claims (1)

1. A kind of structure-improved of steel-plastics composite window curtain rod comprises a body of rod, it is characterized in that: the described body of rod is divided into three-decker, and skin is outer plastic, and the middle level is a metal tube, and internal layer is interior plastic.
