CN2130911Y - Improved horizontal rod for upper rail structure of blind - Google Patents

Abstract

The utility model relates to an improved horizontal rod for an upper rail structure of a blind, which is characterized in that a horizontal rod is made of general low-carbon wire materials by rolling and drawing. When a traditional horizontal rod is primarily rolled and drawn for molding of wire materials with small wire diameter at the upper and lower opposite positions between the roller wheels, due to the characteristic that the horizontal rod is made of the low-carbon wire materials, the materials on both sides of the upper section of the improved horizontal rod circumference is rolled towards both sides of the lower section of the improved horizontal rod circumference in order to keep the part of the main dimension of the improved horizontal rod circumference unchanged. Besides, the improved horizontal rod is arranged between an angle adjusting apparatus and an adjacent supporting seat, and one or more than one convex body for blocking is additionally arranged between two limiting convex bodies which are originally positioned for limiting the taking off of the horizontal rod.

Description

Improved horizontal rod for upper rail structure of blind

The utility model relates to the improvement cross bar of rail structure on the sun blind, system is at the cross bar in the rail structure on the general sun blind, often easily cause on the angular adjustment apparatus of rail one side or the supporting seat come off, disappearance that the blade of the whole sun blind that cause can't be made lifting and angle adjustment improved; And then by the cross bar that will generally make with the low-carbon (LC) wire rod, to practise the less wire rod in the used line of formula cross bar footpath when menophania is oppositely arranged between running roller the roller pulling shaping up and down, must be on the both sides of its periphery hypomere with the material roller of its periphery epimere both sides, can keep the main perimeter dimensions of the former integral body of its cross bar and reach, and especially with between its parallactic angle degree adjusting device and adjacent supports seat, institute is former to be established between the unlikely two spacing convex bodys of deviating from cross bar location, row is set up one or more retaining system convex body again, and make whole cross bar not only can increase greatly outside its intensity, and can be unlikely between the supporting seat of last rail one side or angle adjustment, come off.

And for rail structure on the general sun blind at present, see also first figure, with shown in second figure: it mainly combines location on rail 4 for angular adjustment apparatus 2 and stay cord fastening devices 3 respectively at the both sides section by one, on this in rail 4 spacer segment in conjunction with two or more supporting seat 5, in order to do number such as being inserted with in the cross bar 6 of the stay cord holder 3 of supporting seat 5 for bolt, insert on the angular adjustment apparatus 2 in advance, and make again stay cord holder 3 snap in supporting seat 5 location wait element form on the rail structure; And then by two spacing convex bodys 61 are set in cross bar 6 one sides, make spacing convex body 61 be positioned at scheduling adjusting device 2 and 5 of adjacent supports seats with it, cooperating the other end with whole cross bar 6 to be set as bolt simultaneously inserts and protrudes under the material of this end supporting seat 5 ' one segment length A, reach whole cross bar 6 and located, and unlikely whole cross bar 6 side or the supporting seat 5 ' side within angular adjustment apparatus 2 of causing deviate from separating effect (shown in second figure).

Cross bar 6 in the said structure is made, be to be directly to transfer to processer's processing and manufacturing, and after directly cross bar 6 a large amount of pulls being cut into strip, after pressing two spacing convex bodys 61, finishes the one side blow again, and because of it is to be just directly to give after a large amount of making the assembling dealer to make the assembling operation of rail structure, and because of whole cross bar in a large amount of manufacturing process, it often is some defective products all, especially two of one punching press that side is accepted spacing convex bodys 61, if have wherein arbitrary spacing convex body 61 not to be stamped or punching press bad, advance and directly it is placed on 5 of angular adjustment apparatus 2 and adjacent supporting seats, just will assemble the dealer when assembling should be gone up the rail structure, be all to be to make assembling operation by the mode of calculating payment by general workman, and also complete combination fit on of the cross bar 6 that those are bad, cause whole group of shutter to finish and carry in assembling, and then when being sold in customer's hand, just often easily within angular adjustment apparatus 2 side deviate to separate, and the blade that seriously makes whole sun blind can't be done the phenomenon generation of lifting or angle adjustment, and the utmost point is waited to improve.

This creator because practise on the formula structure state shortcoming, be that its upright making with the dealer of groups of being engaged in various relevant shutter spare parts is bought practical experience for many years, and personal experience, and feel its inconvenience place deeply, thereby active research improves and create, and finishes this case finally.

The main purpose of the utility model, system provides the improvement cross bar of rail structure on a kind of sun blind, especially by number such as bolt on it being inserted with in the cross bar of the stay cord holder of supporting seat, be arranged on its initial desire plant and be positioned angular adjustment apparatus, and and the supporting seat of adjacent positioned between, in order to do being able to unlikelyly deviate to separate between two set spacing convex bodys for cross bar, punching press is set up under one or more the retaining system convex body again, all can make the initial former two spacing convex bodys of only establishing, no matter wherein arbitrary spacing convex body is in initial punch forming process, the defective products that is formed, can be under without screening, directly installing is planted and is positioned between angular adjustment apparatus and supporting seat, can make the retaining system down by the retaining system convex body that added again between this former two spacing convex body, provide especially whole cross bar all can guarantee unlikely fully within the angular adjustment apparatus side, or any side is deviate from separating effect between adjacent supporting seat; Advance and, more just only whole cross bar must be cut under the angular adjustment apparatus and the length between the opposite side supporting seat of rail one side, can guarantee that whole cross bar is unlikely and deviate from separate, and must its two ends must not done under the lengthening of a moderate length as practising the formula cross bar, can reach and avoid that whole cross bar is unlikely deviates from separating effect, and an effect that can reduce the integral material cost relatively greatly is provided.

A time purpose of the utility model still is the improvement cross bar that rail structure on a kind of sun blind is provided; Wherein, general system forms via the roll-in pull with the low-carbon (LC) wire rod because of cross bar, and make it when making roll-forming via the running roller that becomes to be oppositely arranged up and down at first, directly with the low-carbon (LC) wire rod in less line footpath with the material by means of rolling of its periphery epimere both sides on periphery hypomere both sides, and make whole cross bar become the end face of a convex, it (is the section both sides, the end of cross bar that the key dimension part of cross bar periphery can be provided, and whole height), remained unchanged down, be provided as the cross bar of strip, be difficult for as tradition, easily occur bending and deformation (end face that becomes convex because of cross bar), and increase widely under its intensity, more can because of whole cross bar to practise the little wire rod in formula cross bar line footpath, still can reach under the requirement that is same as used at present cross bar periphery key dimension and make, reduce the material of cross bar, and then relatively save the effect of whole cross bar manufacturing materials expense expenditure greatly.
