Description
Technical field
This utility model relates to a kind of object fixing device, more specifically, it relates to a kind of projector fixed mount.
Background technology
Stage performance is generally required for using projector now, real by being fixed on by projector on specific fixed mount
Presenting of existing various pictures.
The most fairly simple to the fixed form of projector, in order to meet Fast Installation, the purpose of easy disassembly,
It is generally all projector to be first fixed on the fixing bar with mounting structure of the two ends, projector is fixed on fixing bar
In one of them mounting head, then the another one mounting head of fixing bar is fixed on crossbeam by the way of rope bundlees,
Fixing bar is used as duty with the most sagging state, the projector below fixing bar in the way of floor projection by picture
Face projects on curtain.
But fix projector by this fixed mount, owing to realizing fixing by the way of binding with cross beam type
, thus it is difficult to the angular adjustment to projector, and there is deviation once the projection angle that projector occurs, dyschezia is with convenient
Make the angular adjustment to projector.
Utility model content
According to above-mentioned shortcoming and defect, the purpose of this utility model is to provide a kind of projection carrying out facilitating angular adjustment
Instrument fixed mount.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of projector is fixed
Frame, including fixing bar, tubular cross bearer, one end of this fixing bar is provided with the fixing end of first coordinated with tubular cross bearer, and the other end sets
The fixing end of second coordinated with projector, the described first fixing end is had to include crook and the connecting portion fixing with fixing bar, institute
State unci be inner surface be the arc section of arc surface and the extension tangent with one end of arc section, described connecting portion level
It is arranged at the other end of extension opposing arcs section, crook is provided with the pine that can crook be fixed on tubular cross bearer
Tight part.
By such scheme, one end of fixing bar is by the second fixing projector of fixing end, and the other end is fixed by first
End fixed cross beam, and on the first fixing end, it is provided with arc section, and arc section and tubular cross bearer can be realized by degree of tightness part
Locking and unblock, when degree of tightness part unlocks the locking of arc section and tubular cross bearer, the inner surface of arc section can be real with tubular cross bearer
Now coordinate the surface along tubular cross bearer to rotate in a circumferential direction regulation, and then realize the convenient regulation of the projection angle to projector, once
After the angle of projector is adjusted surely, immediately screw degree of tightness part so that arc section and tubular cross bearer realize locking, and then make projection
The stationary state of instrument is stabilized, it is achieved final angular adjustment.
Being optimized for further: described degree of tightness part includes regulating bolt, described crook is provided with and regulates bolt thread and join
The regulation screw closed, described regulation bolt intersects through the extended line of the other end of regulation screw with the arc section of crook.
By such scheme, by screwing regulation bolt, the end of regulation bolt will withstand on tubular cross bearer through crook
On, and during continuing to screw, the crook being on regulation bolt extended line will extrude with tubular cross bearer, from
And the extruding realizing crook and tubular cross bearer is fixed.
It is optimized for further: the interior surface curvature of described arc section is from gradually another to arc section of the one end near extension
One end reduces.
By such scheme, by the interior surface curvature of arc section from the one end near extension gradually to another of arc section
End reduces, thus the arc section opening that crook is near extension one side is big, easily buckles on tubular cross bearer by arc section,
More convenient to install.
It is optimized for further: the cornerite of described arc section is more than 180 degree, and regulation screw is arranged at arc section and extension
Junction.
By such scheme, the cornerite of arc section is set greater than 180 degree so that arc section and the bag of tubular cross bearer
Covering more firm, when crook does angle rotation regulation around tubular cross bearer, the rotary state of crook is more stable, it is not easy to
Depart from tubular cross bearer；And regulation screw is located at the junction of arc section and extension, so that whole arc section
Can use with the coordinating of tubular cross bearer, improve the utilization rate of arc section.
It is optimized for further: described fixing bar includes that the end of cross bar is located at by a montant and a cross bar, the described second fixing end
Portion.
By such scheme, fixing bar is arranged to montant and cross bar, and the second fixing end is arranged at the end of cross bar,
The setting of cross bar adds the lateral separation of fixing bar, thus when the angle of the fixing bar of regulation, adjustable range radius will increase.
It is optimized for further: the other end of described montant opposing rail is provided with fastening bolt, described connecting portion is arranged
Having the via that may pass through fastening bolt, this fastening bolt is combined with clamp nut through this via.
By such scheme, by fastening bolt being passed the via on connecting portion, the most again will be tight by clamp nut
Fixing bolt and connecting portion realize fixing, and the installation completed between fixing bar and the first fixing end is fixed.
It is optimized for further: described montant and cross bar are connected by an arc-shaped transition section.
By such scheme, realized the connection of montant and cross bar by arc-shaped transition section, when upslide is installed in the end of cross bar
The when of shadow instrument, the junction between cross bar and montant is that stress concentration portion is divided, and is arranged to the junction of cross bar and montant
Arc-shaped transition section is conducive to the dispersion of stress, improves the service life of whole fixing bar.
It is optimized for further: the described second fixing end includes the sucker of one and projection surface adhesive.
By such scheme, easily the surface of projector can be carried out adhesive by sucker, install quick and convenient.
It is optimized for further: described second fixes the connecting rod that end also includes that one end is fixedly connected on sucker, connecting rod
The other end be provided with union joint, this union joint is rotatably connected along the axial close-fitting of cross bar with crossbar end.
By such scheme, by the union joint being axially rotatably connected with cross bar along cross bar, it is possible to realize projector around
The axial rotation of cross bar, and then realize 360 degree of angular adjustment effects of orthographic projection picture of projector picture to curtain.
It is optimized for further: this connecting rod is connected by universal spherical joint with union joint relative to the other end of sucker.
By such scheme, facilitate the low-angle regulation of projector opposing rail, and in order to realize angular adjustment after
Locating effect, is chosen as the universal spherical joint of that class close-fit by universal spherical joint, i.e. needs firmly to pull hue angle when, angle
Degree adjustment can be automatically obtained location positioning after completing.
In sum, coordinating by crook and tubular cross bearer, it is possible to realize the effect of fast assembling-disassembling, and by pine
The quick degree of tightness effect that tight part is capable of between crook and tubular cross bearer, when crook relaxes with tubular cross bearer, it is possible to
Rotating the relative angle regulation between crook and tubular cross bearer, regulation puts in place and tightens degree of tightness part afterwards and be i.e. capable of crook
And again fixing between tubular cross bearer；And fixing bar is arranged to the mode of cross bar and montant, by increasing cross bar and then increasing
Add the angular adjustment radius of fixing bar, the most also increase the angle of regulation range of projector；By by the second fixed part
It is arranged to the mode of sucker and connecting rod, and connecting rod is fixed by universal spherical joint with cross bar, it is achieved that projector is the most horizontal
The angular adjustment of the little scope of bar, further increases the tunable performance of projector.
