Abstract

The utility model relates to a hanger rod for hanging curtains, specifically a curtain rod with large bending resistance. It has an axial through-hole in the middle part of the curtain rod, wherein a powerful support bar is plugged in the hole. The utility model based on the existing curtain rod structure provides an additional powerful support bar of interpolating type, improving the curtain rod's capacity of resistance to sag and deformation, thereby effectively overcome the ordinary curtain rod's shortage of deformation and sag. The utility model has advantages of simple structure, convenience for fabrication, high decorative quality, reduced sag and deformation, and low cost, meeting different consumer demand in the market.

Description

A kind of powerful bending resistance curtain rod

Technical field

The utility model relates to a kind of suspension rod that hangs curtain, specifically a kind of powerful bending resistance curtain rod.

Technical background

Because the room is built increasingly, the length that curtain rod is installed is also more and more longer.Since every root window curtain rod can only have at the most when mounted two ends and centre totally three be connected and fixed the strong point, so the sag bent phenomenon of curtain rod is also more and more general.Commercially available curtain rod has various ways such as aluminium section bar bar, solid wood bar, iron skill bar and the plastic bar of steel pipe at present.The wall thickness of aluminium section bar bar is thinner, and intensity is lower, easy sagging distortion behind the curtain; The good decorating effect of solid wood bar, but on the high side, and also have the sagging defective of distortion; The bearing of iron skill bar is good, is difficult for saggingly, but the price height uses noise big, and draws curtain to send out heavy; The bearing of the plastic bar of steel pipe is good, use noise little, but cost of manufacture is higher relatively, and surface abrasion resistance is relatively poor.

The utility model content

The purpose of this utility model just provides a kind of powerful bending resistance curtain rod, to satisfy the consumption orientation demand of consumer's high-quality low-cost.

The utility model is achieved in that this powerful bending resistance curtain rod is to have axially extending bore at curtain rod body of rod middle part, and pegging graft in the hole is combined with powerful support bar.

Design philosophy of the present utility model is exactly on the appearance structure basis of existing curtain rod, in the body of rod of curtain rod, set up the powerful support bar of an interpolation formula, make the anti-sagging ability of load-bearing of section bar curtain rod reach the height of iron skill bar or the plastic bar of steel pipe, thereby overcome the yielding sagging deficiency of general window curtain rod effectively.Because powerful support bar is built-in form, thus for the body of rod of curtain rod, on the one hand can be because of the reduction of requirement of strength, and select softer aluminium of material or Wood-plastic material extrusion molding for use, to reduce material cost; On the other hand, the outside body of rod also can add color masterbatch etc. when moulding, to form shades of colour and texture, to exactly like the curtain rod of solid wood effect, perhaps by to the spraying paint of body of rod outside, pad pasting, transfer printing or engraving etc., make the curtain rod of multiple different expression form, thereby can improve the decorative effect and the class of curtain rod.Powerful support bar cooperates with the grafting of the outer bar of curtain, and technology is simple, the cost increase seldom, but counter-bending deformability significantly improves, and solved counter-bending deformation effect difference of common low price curtain rod and the not high drawback of outward appearance class thus.The utility model is simple in structure, and processing and fabricating is convenient, and have ornamental strong, be difficult for multiple characteristics such as sagging distortion and cost are low, can satisfy the different consumption demands in market.

Description of drawings

Fig. 1, Fig. 2, Fig. 3 are the cross-sectional view of three kinds of specific implementations of the utility model.

The specific embodiment

As shown in drawings, this powerful bending resistance curtain rod is to have axially extending bore 4 at the curtain rod body of rod 1 middle part, and pegging graft in the hole is combined with powerful support bar 2.Wherein the external form of the curtain rod body of rod 1 can adopt the version of existing various curtain rods, promptly can be round bar, band upper hopper chute bar, be with downslide channel bar, the embedding bar of anti-draw runner the (Fig. 1) or make anti-sliding fin bar various ways such as (Fig. 2, Fig. 3).The body of rod 1 can the aluminium alloy material or Wood-plastic material etc., uses extruder for shaping.Can make the middle part axially extending bore 4 of the body of rod 1 and other groove or rib thus simultaneously, also can make the structure hole (Fig. 1) on the body of rod periphery simultaneously,, further reduce material cost to reduce the material usage of the body of rod 1.In the end face groove of the curtain rod body of rod 1 shown in Figure 1, can be by original frame mode anti-draw runner 3 of pegging graft.On Fig. 2, the curtain rod body of rod 1 shown in Figure 3, be shaped on axial anti-sliding fin.

Powerful support bar 2 is preferably selected the strong steel pipe of support force for use, and its cost performance is the most reasonable.The cross section of powerful support bar 2 can be various geometries such as circle, ellipse, square or triangle.The cross sectional shape of the through hole 4 on the body of rod 1 can be and the identical or different geometry in powerful support bar 2 cross sections, as long as the two can contact cooperation preferably.The outer profile size of powerful support bar 2 should be slightly less than the interior overall size of body of rod through hole 4, cooperates with the grafting that makes things convenient for the two.Preferably the interior edge of the through hole 4 at the curtain rod body of rod 1 middle part make some in fin 5.So both can make things convenient for the grafting of the two to cooperate, the body of rod 1 is contacted with the periphery of powerful support bar 2, thus the supporting role that improves 2 pairs of bodies of rod 1 of powerful support bar.

This curtain rod intercepts the curtain rod of respective length as required when installing and using, be equipped with to go up the curtain rail suspension ring, sign indicating number is installed and decorates first-class parts again, can form a complete curtain rail.
