Description
Technical field
The utility model relates to a kind of light frame that light is installed aloft, relates in particular to a kind of light frame that light of stage is installed.
Background technology
At present domestic light frame is of a great variety, form is different, and light of stage frame in the past is splicing construction fixing and simple plug-in type, exists to install complicatedly, moves and the problem of keeping inconvenience.They have a total defective to be: can hang the shelf of a lot of light fixtures, structure is all comparatively complicated, involve great expense; And simple shelf, form and quantity are single on light suspension problem, waste time and energy, and can not satisfy the specification requirement of stage for light; Especially after the light frame that can regulate height can only install on the ground light fixture is adopted the mode of mechanical lifting, make it be stabilized in desirable height, the maximum defective of this form is, the back personnel can't utilize the shelf adjustment of ascending a height in case light fixture raises.
Summary of the invention
The purpose of the utility model is the awkward problem to above-mentioned existing light frame, designs a kind of new folding light frame.
The purpose of the utility model realizes through following structure:
A kind of collapsible light frame comprises light frame base and merogenesis plug-in type ladder.Said light frame base comprises four identical base supports; Wherein, Two base supports are connected with terraced bracing frame pivoting that is positioned at their centres, constitute a group of light frame base, and two base supports also are connected with another the terraced bracing frame pivoting that is positioned at their centres in addition; Constitute another group of light frame base, settle in opposite directions symmetrically for two groups of said light frame base; Described terraced bracing frame is the square shape structure, and being pegged graft by the concave shape framework of upper cross-beam and below assembles; Each base support is equipped with a universal wheel in the bottom at its terminal, and universal wheel top has the L shaped transverse plate that can place the opposite side base support; Have a load-bearing axle sleeve on each terraced bracing frame lower crossbeam, plug with the plug of lower ladder; Each terraced bracing frame upper cross-beam is provided with the ladder securing member with lower ladder corresponding site, and terraced bracing frame and ladder are tightened together.
The characteristics of the utility model are:
1, all adopt the assembly form of plug-in unit quick for installation easy, in minutes can be through the personnel of simple training smoothly with its assembled.
2, the height of light frame is made up of several groups of identical vertical cell, can require to carry out the plus-minus adjustment of unit according to different height, reaches required height.
3, the vertical cell of light frame is the ascending stair form, and the operator is stood on the ladder, carries out ascend operations such as lamp installation debugging at various height, and the ladder that scrunches of vertical cell also can be used as the usefulness that the personnel of ascending a height hang safety belt in addition.
4, the light frame can be folding with the light frame no the time, and form the very vehicle structure of I to carry out of a volumes, carries out the scene easily and move carrying and collection.
5, on the light frame except tip designs light install the cross bar, also designed the auxiliary peg of one group of light in addition, the auxiliary peg of this group can increase the installation quantity of light and carry out the adjustment of light height easily at the differing heights of light frame.
The primary structure of the utility model is to be processed by various metal pipe materials, and different is with other common light framves, and no matter this kind of light frame is in normal the use; It is quick to have assembling, uses reliable and stablely, and the application scenario is extensive; And the back convenient disassembly of finishing using; After being folded together, the collection keeping space that not only needs is very little, and the special tectonic of meeting utilization after the light frame is folding itself; Through the universal wheel on the light frame, can form a light push-and-pull and move as dolly.What the utility model light frame adopted is to be the main body with the ladder form, and operating personnel are ascend operation very easily, and the position of finer adjustment light fixture makes its best effect of light fixture performance.The utility model light frame and former existing light frame institute difference are following:
1, vertical component has adopted the ascending stair form; Such design makes the horizontal treadle of each ascending stair all can be used as the height of light frame; The adjustment flexibility of light fixture suspension height is increased greatly, also made things convenient for the Field Force to utilize ladder structure to ascend a height in addition and carried out the operation of trickle position adjustment for the light fixture that has installed.
2, increased the auxiliary hanger bar of light frame, so not only can be in the installation of the enterprising portable lighter tool of light fixture bar on top, and can utilize the installation quantity of auxiliary rod increase light fixture.
When 3, the light frame is collected; The two groups of support sections in light frame bottom can be through splicing each other; Constitute the vehicle structure that can load vertical ascending stair unit, the characteristics of this structure have two, and the one, the mid portion of the two groups of support units in bottom is designed to U type structure; Such structure can be placed the light shelf attachment that needs to load wherein; All like this parts just can form one and be easy to the condensate that transports and take care of, in addition under the effect of light frame universal wheel, light frame after folding can be moved easily and certainly.
