Ensure the display effect of large screen projector.
The technical solution of the utility model is：A kind of aluminium section bar of projector screen's frame, including cross section are rectangle
Proximate matter ontology, the both ends of the surface center of the proximate matter ontology is respectively equipped with the installation threaded hole extended longitudinally, proximate matter ontology with
Axial symmetry is set there are four the connection mortise parallel with installation screw thread axially bored line centered on installation threaded hole, and each mortise that connects is along type
The longitudinal direction of material ontology is run through, and each truncation surface for connecting mortise is rectangle, a length of the proximate matter ontology rectangular cross section
Integrally formed with the screen mounting portion in cantilever-shaped protrusion, the longitudinal length and proximate matter of the screen mounting portion on side wall where side
The longitudinal length of ontology is identical, and several hanging holes, these hanging holes etc. are arranged in the longitudinal arrangement of the screen mounting portion upper edge proximate matter ontology
Spacing, which is uniformly distributed, to be arranged on screen mounting portion.
The upper surface of the screen mounting portion is vertical with side wall where a long side of proximate matter ontology rectangular cross section.
The phase in obtuse angle of side wall where one long side of the lower face of the screen mounting portion and proximate matter ontology rectangular cross section
It hands over, the lower face of screen mounting portion is made to form the inclined-plane for tilting extend upwards.
The protrusion height h of the screen mounting portion is 5-10mm.
It is had the advantages that using above-mentioned technical proposal：
1, the aluminium section bar of projector screen's frame includes the proximate matter ontology that cross section is rectangle, and the two of the proximate matter ontology
End face center is respectively equipped with the installation threaded hole extended longitudinally, and proximate matter ontology axial symmetry centered on installing threaded hole is equipped with four
A connection mortise parallel with installation screw thread axially bored line, each mortise that connects run through along the longitudinal direction of proximate matter ontology, respectively connect mortise
Truncation surface be rectangle, by be arranged the perforative connection mortise in four longitudinal directions, both mitigated the weight savings aluminium of proximate matter ontology
Material, while ensureing the structural strength of proximate matter ontology, by connector by the combination of proximate matter ontology connect and compose specific length crossbeam,
Longeron, then realized the crossbeam of specific length, projector screen's frame of stringer combination composition predetermined size fast by connector
Speed assembling satisfies the use demand, and projector screen's frame of combination also can be quickly disassembled into more proximate matter sheets of uniform sizes
Body, convenient for storage and transport.Integrally formed in cantilever on side wall where one long side of the proximate matter ontology rectangular cross section
The screen mounting portion of shape protrusion, the longitudinal length of the screen mounting portion is identical as the longitudinal length of proximate matter ontology, screen peace
Several hanging holes are arranged in the longitudinal arrangement of dress portion upper edge proximate matter ontology, these hanging holes, which are equidistantly uniformly distributed, is arranged in screen mounting portion
On, after combining the projector screen's frame for constituting predetermined size by proximate matter ontology, screen mounting portion is around projector screen's frame
Frame one week realizes Fast Installation, dismounting projector screen for being tensioned projector screen by hook.Due to screen mounting portion
Around projector screen's frame one week, moreover it is possible to effectively be tensioned projector screen, ensure drop shadow effect.
2, side wall where a long side of the lower face of the screen mounting portion and proximate matter ontology rectangular cross section is in obtuse angle
Intersection makes the lower face of screen mounting portion form the inclined-plane for tilting extend upwards, inclined-plane and the proximate matter ontology of screen mounting portion
The bit space that allows for mounting projector screen is formed between side wall, convenient for Fast Installation, dismounting projector screen.
It is further described with reference to the accompanying drawings and detailed description.
