Description

TECHNICAL FIELD

[0001] The utility model relates to the field of window decoration, more specifically, it relates to a kind of anti-bending window decoration rod. BACKGROUND

[0002] Window decoration rod (also known as curtain rod, curtain rail) is a core functional component for hanging and supporting curtain, window screen and other cloth decorative, The window decoration rod in the prior art is generally not too long, and the middle of the window decoration rod may be bent when the long window decoration rod bears window decoration, which may cause deformation, loose connection and other problems of the window decoration rod in the long run.

[0003] Therefore, a new scheme is needed to solve this problem. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies in the prior art, the utility model aims to provide an anti-bending window decoration rod.

[0005] The above technical purpose of the utility model is realized by the following technical scheme: the anti-bending window decoration rod comprises a hollow rod body, a curve-preventing rod is arranged inside the rod body, the curve-preventing rod is arc-shaped, the middle part of the curve-preventing rod abuts against the upper end of the inner wall of the rod body, and the two ends of the curve-preventing rod abut against the lower end of the inner wall of the rod body.

[0006] The utility model is further provided as follows: first and second ribs are arranged inside the rod body, the first and second ribs are vertically arranged, and a cavity for mounting the curve-preventing rod is formed between the first and second ribs.

[0007] The utility model is further provided as follows: a plurality of curve-preventing ribs are arranged on the side of the first rib away from the cavity and the side of the second rib away from the cavity.

[0008] The utility model is further provided as follows: an indicating plane is formed at the bottom of the rod body.

[0009] The utility model is further provided as follows: end covers are fixedly connected to the two ends of the rod body, the end rod comprises an insertion part inserted into the interior of the rod body, and the insertion part abuts against the two ends of the curve-preventing rod.

[0010] In summary, the utility model has the following beneficial effects: the curve-preventing rod is arc-shaped, and the two ends of the curve-preventing rod form three-point pre-tightening support with the inner wall of the rod body, so that when the rod body is subjected to external force (such as the weight of the curtain and installation stress), the reverse pre-tightening force can offset the bending moment and reduce the bending deformation. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 The structure of the utility model is shown in the figure; Figure 2 This is a partial sectional view of the present invention.

[0012] In the diagram: 1. Rod body; 2. Anti-bending rod; 3. First rib; 4. Second rib; 5. Chamber; 6. Anti-bending rib; 7. Indicating plane; 8. End cap; 9. Extension part. Detailed Implementation

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] Example: A type of anti-bend window trim rod, such as Figure 1 As shown, the device includes a hollow rod body 1, which is made of extruded aluminum alloy and has a through cavity along its length. An anti-bend rod 2, made of spring steel, is installed inside the cavity and has an upwardly arched arc structure. The middle part of the anti-bend rod 2 abuts against the upper end face of the inner wall of the rod body 1, and both ends abut against the lower end face of the inner wall of the rod body 1, forming a three-point pre-tensioned support.

[0015] The rod body 1 has a first rib 3 and a second rib 4 inside, which are vertically welded to the bottom surface of the rod body to form a vertical separation structure. A cavity 5 is formed between the first rib 3 and the second rib 4, and the anti-bending rod 2 is embedded in the cavity 5 with an interference fit.

[0016] Two anti-bending ribs 6 spaced 10mm apart are provided on the outer side of the first rib 3, and two anti-bending ribs 6 are also provided on the outer side of the second rib 4. Each anti-bending rib is 10mm high to enhance the bending resistance of the pole.

[0017] The bottom surface of the rod 1 is milled to form a width indicator plane 7, which is parallel to the axis of the rod. A red marking line is sprayed on the surface to align it with the reference surface of the window frame during installation, and also to indicate the bending direction of the rod.

[0018] Both ends of the rod 1 are fixed with end caps 8 by snap fasteners. The extension part 9 of the end cap 8 is a stepped cylindrical structure with a diameter that matches the cavity 5. The end of the extension part 9 has a 2mm protrusion, which presses the two ends of the anti-bend rod 2 to achieve axial limitation.

[0019] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
