Description

A kind of adjustable universal street code

Technical field

The present invention relates to the installing area of cable, especially a kind of adjustable universal street code.

Background technology

When street code is cable laying line, for the device of stretching attached cable line.Street code is installed, whether dismounting is convenient, the direct length affecting the aerial work time, if not convenient, then can increase the work high above the ground time, increase construction risk, dismounting trouble more can cause being unfavorable for the problem of subsequent treatment, maintenance and recycling, and whether wire connects safe and reliable, be related to the personal safety of people especially, especially need to pay attention to.

Traditional street code by the gold utensil support can followed closely on metope (gold utensil support comprise the base that can fix with body of wall and can be fixing with iron bar support), porcelain vase and for the iron bar be fixed on gold utensil support forms by porcelain vase, when circuit crosses street code, general through porcelain vase, cable and porcelain vase are bundled fixing by the mode that metal wire is wound around again, this street code not only uses trouble, construction risk, and be usually only applicable to wire extends (without corner) occasion in rectilinear direction, and be not suitable for the fixing of corner cable; If only use one group of street code, then solidus loosely, is the needs meeting fixing corner cable, usually can each She Yizu street code on both sides metope on the corner, and the cable before and after fixing corner, workload is multiplied, troublesome poeration, and the aerial work time is long.For the ease of fixing corner cable, existing publication number is that the Chinese patent of CN203617650U discloses a kind of robust corner street code, by will the band iron that plate that two pieces is 90 ° to fixing angle forms be arranged and the porcelain be fixed on band iron is commonplace, during use, this band iron is fixed on the body of wall of 90 ° of corners, again by cable metal wire binding be fixed on porcelain commonplace on, this kind of structure decreases labour intensity to a certain extent, but applicability is but not strong, very flexible, body of wall is not all 90 ° of corners on the one hand, if body of wall is other corner mode, then inapplicable, on the other hand, be only applicable to the situation that body of wall is 90 ° of corners, be not suitable for the body of wall of non-corner.If meet change circuit or other is when needing again cabling, when existing street code (quick installing cables device) is taken off recycling from cable, unlock intricate operation, be not easy to dismounting, extend the aerial work time of workmen.Existing street code poor universality, not only can not be common to non-corner and different corner occasion attached cable, and can not fix the cable of different wire diameter easily.

Summary of the invention

It is simple that task of the present invention is to provide a kind of structure, and be easy to processing, highly versatile, easy and simple to handle, quick, fail safe is good, and clamped cable is firm, long service life, and cost is low, is easy to the adjustable universal street code loaded and unloaded.
