Description

Folding rack
Technical field
It the utility model is related to a kind of folding rack.
Background technology
In the wild or the occasion such as indoor large arenas is temporarily using light fixture, photographic goods or when carrying out haywire wiring, generally Need to use lifting support.Lifting support generally comprises base and elevating lever, by the way that elevating lever is raised, realizes the high-altitude of light fixture Illumination or the fixed point shooting of photography instrument.Certainly, lifting support can also be used to use during aloft mounting.
In order to facilitate storage, the base of existing lifting support is generally foldable, for example, in CN205664325U and The bracket with foldable base provided in CN203215614U.Wherein, the folding base seat used in CN205664325U includes master Sleeve pipe and the be hinged supporting leg for being distributed in main sleeve bottom, when not in use, folding storage after supporting leg can rotate along pin joint, just In carrying.The understructure used in CN203215614U includes upper cross frame and lower cross frame base, upper cross frame Including four umbrella stands, umbrella stand end is corresponding with the mid-stent of lower cross frame to be movably hinged, the upper cross that seat structure includes Support and lower cross frame Foldable.The understructure of above two structure is simple, but in the wild using meet with high wind when Easily rock.
Therefore, CN1693122A discloses a kind of fast folding rack for illuminating vehicle, it is made up of fall way and support, wherein, The fixed mount of support carries the cross wing;Support bar is fixed with bolt, band elongated slot, fixed mount above support bar on the cross wing Band elongated slot, outer boom are hinged on by rotating shaft in the elongated slot of the fixed mount cross wing and support bar above the cross wing;Outside There is pallet the distal end of boom with being screwed, and outer boom is fixed with spring case close to one end of fixed mount, its both sides cutting elongated groove, interior Spring is put, bearing pin withstands on the end of spring, and draw ring is fixed on bearing pin, and bearing pin can slide along the elongated slot on spring case.When putting down Outer boom or when packing up outer boom, by pulling draw ring compression spring, can take bearing pin from the hook or groove of the cross wing Go out, expanded position or folding position are reached so as to rotate outer boom;Under the action of the spring, bearing pin can be bound to fixation automatically Realize in the hook of the frame cross wing or in groove and fix.This folding rack, realized by bearing pin, draw ring, spring case, spring outer Boom two kinds of positions restriction, it is easy when using in the wild wherein the spring structure used is complex and partial denudation It is damaged, moreover, being arranged at end position of the outer boom close to fixed mount for the bearing pin of fixed outer boom and rotating shaft, leads Used time stress is caused to compare concentration, the stability of whole support will necessarily be affected.In addition, above-mentioned support is outer by being arranged on The pallet adjustment of the distal end of boom so that outer boom is easily destroyed by wind when in use, and this have impact on to a certain extent The stability that support uses.
