Abstract
The utility model relates to a fence, particularly a fastener used for connecting fence rods. According to the design proposal provided by the utility model, two end parts of a pair of elastic slices are mutually connected and the other two end parts of the elastic slices separately bend inwards after obliquely extending outwards to form two opposite elastic hooks. The connecting ends of the elastic slices separately obliquely extend outwards after connected with each other and then separately bend inwards to form two elastic hooks. The utility model can effectively improve the coupling stiffness and fastness of the whole fence and also has the advantages of simple structure and low manufacturing cost.
Description
Technical field
The utility model relates to fence, specifically a kind of fastener that is used to connect grate bar.
Background technology
Popular in the market fence compound mode has board plug type and wears two kinds of wire types, the major defect of this dual mode is: 1, no matter a door frame fence is a horizontal bar more than two or two, when external force adds therein on the horizontal bar, have only this root horizontal bar stressed, cause stressed horizontal bar flexural deformation, when distortion was excessive, the plate that is inserted on the perpendicular hurdle very easily pitched; 2, these two kinds of modular fences when mounted, in order to guarantee on the perpendicular hurdle positional precision of inserting plate hole up and down, must improve machining accuracy must, increase expense expenditure; In addition, when the processing horizontal bar, have buckling phenomenon among a small circle, make perpendicular hurdle be loosening state, reduced the security reliability on perpendicular hurdle.
Summary of the invention
The purpose of this utility model is to design a kind of locating connector of modular fence, and this device can effectively improve the coupling stiffness and the fastness of whole door frame fence, makes fence safer, more reliable; And this apparatus structure is simple, cheap for manufacturing cost.
According to design scheme provided by the utility model, an end of a pair of flexure strip interconnects, and after the outward-dipping extension of another end difference of flexure strip, curves inwardly again, forms two relative elastic hooks.
Further feature is: the link of a pair of flexure strip is distinguished outward-dipping extension again after interconnecting, and then curves inwardly respectively, forms two other elastic hook.
Further feature is: a flexure strip connecting portion in a pair of flexure strip is provided with through hole, at the connecting portion of another flexure strip projection is set, and projection cooperatively interacts with through hole and is connected.A pair of flexure strip is formed by an elastic webbing bending, after the outward-dipping extension of two ends difference of elastic webbing, curves inwardly respectively again, forms two relative elastic hooks.
The utility model has the advantages that: 1, this device relies on the elastic deformation of material that the cross bar and the montant of fence are carried out mechanical interlocking, makes cross bar and montant relative fixed, can not move, and forms the framework with certain rigidity; But 2, the transmission of this device realizable force, when external force adds allly on fence during any one part, this power can be distributed on the whole door frame fence, and the stressed flexural deformation of whichever workpiece all is not easy to take off; 3, this device connects reliably, makes simple, low processing cost.
Description of drawings
Fig. 1 is user mode figure of the present utility model.
Fig. 2 is a structure chart of the present utility model.
Fig. 3 is an another kind of structure chart of the present utility model.
The specific embodiment
As shown in the figure: an end of a pair of flexure strip 3 interconnects, and after the outward-dipping extension of another end difference of flexure strip 3, curves inwardly again, forms two relative elastic hooks 2.
The link of a pair of flexure strip 3 is distinguished outward-dipping extension again after interconnecting, and then curves inwardly respectively, forms two other elastic hook 2 ', sees Fig. 2, all forms an elastic hook on four angles of flexure strip, is commonly called as two-way positioning spring card.During use, earlier Spring Card is fit in advance in the perpendicular hurdle 6,4 elastic hooks 2 can eject respectively outside 4 apertures that are arranged on the perpendicular hurdle 6, see Fig. 1, with horizontal bar 7 combination the time, at first to contact two elastic hooks of horizontal bar 7 with the have gentle hands flicking with firmlying, get final product and will erect in the hurdle 6 insertion horizontal bars 7.Its mechanism of action is: after in the bidirectional spring card inserts perpendicular hurdle 6,4 elastic hooks can eject from 4 apertures on the perpendicular hurdle 6 automatically by elastic force up and down, make the fixed-site of Spring Card in perpendicular hurdle 6; After perpendicular hurdle 6 inserted in the horizontal bar 7, the position relative fixed of perpendicular hurdle 6 and horizontal bar 7 and two-way positioning spring card played the effect that connects with the power of transmission.
The connecting portion of a flexure strip in a pair of flexure strip 3 is provided with through hole 4, at another flexure strip connecting portion projection 5 is set, and projection 5 cooperatively interacts with through hole 4 and is connected.Described connected mode can have multiple, comprises welding, riveted joint etc., but when utilizing this inserting mode of projection and pit, more convenient in installation and transportation, when especially transporting, can be with each sheet flexure strip respectively as loose mail, pack after the mutual superposition again, to save transport space.
A pair of flexure strip 3 is formed by an elastic webbing bending, forms convex structure in curved top portion, after the outward-dipping extension of two ends difference of elastic webbing, curves inwardly respectively again, forms two relative elastic hooks 2.This structure is commonly called as unidirectional positioning spring card, see Fig. 3, during use, same earlier Spring Card the insertion erected in the hurdle 6, when perpendicular hurdle 6 is inserted into Spring Card top circular arc when touching diapire in the horizontal bar 7, two elastic hooks 2 eject automatically, at this moment, the height of Spring Card and horizontal bar inwall measure-alike etc., Spring Card is fixed in the horizontal bar, can not displacement on the direction in the drawings, Spring Card has only two elastic hooks to stretch out outside the aperture on the perpendicular hurdle 6 in perpendicular hurdle 6, by two elastic hooks, perpendicular hurdle 6 also is fixed on the horizontal bar 7 and can not moves.Therefore, by the transfer function of unidirectional spring card, no matter be lateral stressed, still perpendicular hurdle is stressed, and these 3 parts are simultaneously stressed.
