Description

The expansion stretched out structure of mobile stage truck background board

The utility model relates to a kind of mobile stage truck background board, particularly a kind of expansion stretched out structure of mobile stage truck background board.

Taiwan patent [being applicable to the activity context plate of stage vehicle] as No. the 86208534, No. 320988 application number of notification number, as shown in Figure 7, its background board is to be located on the stage to articulate the small size plate face of forming a little general layout by first flap and second flap, between launching to use and fold so the inevitable effect of its stage background that can arrange is little artificial specialized operations must be arranged, pretty troublesome in the use; And become stage property after accepting and carry with car, increase managerial burden, to worry also to have forgotten that band or band are incomplete, really trouble is the more.

So how on stage vehicle, can face upward and outside open operation top wall structure improvement design in addition again, make it can further enlarge to face upward and launch to become a big face stage background plate face.And can so that use, be the difficulty place that solves for the utility model institute desire by the unified operation of roof development mechanism.

Main purpose of the present utility model is that a kind of expansion stretched out structure of mobile stage truck background board is being provided, its can stage vehicle roof directly launch to enlarge as a large-scale stage background plate face, rich, the variability that can increase that stage background arranges is to provide preferable stage background effect.

Of the present utility model time a purpose is that the expansion stretched out structure of mobile stage truck background board is being provided, and it launches and folds all and can be operated by the control mechanism unification of stage roof, and convenient the use also do not have the trouble of carrying.

Above-mentioned purpose of the present utility model is realized by following technical scheme.

A kind of expansion stretched out structure of mobile stage truck background board, it is a riser upside of mainly on the wagon box of the headstock rear side of stage vehicle, erectting, backward with roof mainboard of pivot junction spreading, and the two roof side plates that promote to stretch with cylinder pressure that are pivoted in roof mainboard both sides, making to pivot the roof mainboard faces upward into vertical, and two roof side plates are expanded laterally open, become a big face upright to background board, the layout stage background is provided, it is characterized in that: a plurality of bracing or strutting arrangements all can be established and combination support one roof extension board in this two roofs side plate back side, the set pushed section, the outside that cooperates the roof extension board and roof side plate be set to push away the relative combination of the device of pulling, make the outer slide plate of roof can extrapolated again roof side plate, and form a roof background board face that enlarges, provide stage background that bigger layout and variation space are arranged.

Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:

Wherein sliding support is mainly to be horizontally set with many clad type wheel tracks at the side plate back side and to provide that the set pulley of slide plate opposite side is inserted in slippage outside the roof, and push away the device of pulling is in the set outwardly directed cylinder pressure of roof side plate, combine with the pushed section of cylinder pressure outer end with the roof extension board outside, make two roof extension boards push away to pull and outwards skid off the roof side plate again, and form a roof background board face that enlarges by cylinder pressure.

It can tie device in conjunction with the roof extension board with pivot in the outer side edges of roof side plate, it can outwards be turned down in the roof side plate outside again launch; And its bracing or strutting arrangement be can be in roof side plate inboard with a permanent seat in conjunction with an outer tube, outer tube noose one inner sleeve and in tube wall with a packing screw to inner sleeve packing fix, the inner sleeve outer end is in conjunction with a plate holder with folder mouth, make can unclamp behind the outer tube packing screw protruding with folder mouthful chuck in the roof extension board that turnover launches, tighten the packing screw in outer tube again and fix.

Its pivot knot device is a hinge.

Advantage of the present utility model is:

The structural slab face design that the utility model is further enlarged by the stage vehicle top wall structure again, provide stage background that bigger layout and variation space are arranged: and its operation of taking down the exhibits can be undertaken by the roof control mechanism unification of stage vehicle, not only use and go up conveniently, also do not have the troublesome problem of carrying.

Now conjunction with figs. is enumerated a specific embodiment below.Introduce structure content of the present utility model in detail, and the function and benefit that can reach:

Fig. 7 is the stage vehicle background board block diagram of prior art.

Be illustrated in figure 1 as schematic perspective view of the present utility model, it is riser 11 upsides of mainly erectting on stage vehicle 10 headstock rear side wagon boxes, backward with roof mainboard 20 of pivot junction spreading, and the two roof side plates 22 that promote to stretch with cylinder pressure 21 that are pivoted in roof mainboard 20 both sides, make and roof mainboard 20 can be pushed away support by cylinder pressure and pivot and to face upward into vertical, again two roof side plates 22 are expanded laterally with cylinder pressure 21 and open, become a big face upright to background board; And all can establish a plurality of bracing or strutting arrangements in these two roofs side plate, 22 back sides again and combination support of a specified duration one roof extension board 30, the set pushed section 31, the outside that cooperates roof extension board 30 and roof side plate 22 be set to push away the relative combination of the device of pulling, roof extension board 30 can be stretched out again release roof side plate 22, and form a roof background board face that enlarges, provide stage background that bigger layout and variation space are arranged.

As shown in Figure 2, this support assembling device is to be horizontally set with a plurality of clad type wheel tracks 23 in these two roofs side plate, 22 back sides, and provide the set pulley 32 of roof extension board 30 opposite sides to be inserted in, and push away the device of pulling be for be located at the roof side plate to overhanging cylinder pressure 21, become with set pushed section 31 combinations of these cylinder pressure 21 outer ends and roof extension board 30 outsides, make and can be as shown in Figure 3 push away when pulling this pushed section 31 when the cylinder pressure 21 in these roof side plate 22 outsides, pulley 32 by these clad type wheel track 23 inner support two roof extension boards 30, make roof extension board 30 can outwards skid off the roof side plate, look like shown in the layout effect photo figure of Fig. 7 and further enlarge a sheet of roof background board of formation again.

Be illustrated in figure 4 as second kind of car embodiment schematic perspective view of the present utility model, it is can tie device (can be a hinge 24) pivot with pivot in the outer side edges of roof side plate 22 to tie this roof extension board 30, it can outwards be turned down in roof side plate 22 outsides again launches, cooperation can make the outside at roof side plate 22 in conjunction with permanent seat 25 by the set bracing or strutting arrangement of roof outer panel, permanent seat 25 is in conjunction with an outer tube 26, inner sleeve 27 of outer tube 26 nooses also can be fixed the inner sleeve packing with a packing screw 28 in tube wall, and the inner sleeve outer end is in conjunction with a plate holder 29 with folder mouthfuls 291; Make and unclamping protruding folder mouth 291 chucks with plate holder 29 in outer tube 26 packing screws 28 back in roof extension board 30, tightening packing screw 28 in outer tube 26 again fixes as shown in Figure 6, the top walls panels face after also but firm support enlarges, and a larger area stage background plate face is provided.
