Less used.
2) make act frame although intensity is high with steel plate bending, but machining accuracy is difficult to ensure that, and weight is too heavy, inconvenience
Install.
3) mask is fixed on periphery, the method be only applicable to periphery have can bearing situation, versatility is strong, only
Suitable specific project.
Under such a technical background, we disclose one kind and be based on distortion-free aluminum screen frame.
Content of the invention
The present invention is directed to the deficiencies in the prior art, there is provided one kind effectively prevents screen from deforming because of load-bearing, improves and uses
Life-span based on distortion-free aluminum screen frame.
The present invention is to solve above-mentioned technical problem, there is provided technical scheme below：One kind is based on distortion-free aluminum screen
Framework is mutually spliced into four curtain frame assemblies of framework, fixed frame splicing end side surface and bottom it is characterised in that including head and the tail
L-type connector and connection fixture, the two ends of every curtain frame assembly are all cut into 45 degree of angles, and adjacent curtain frame assembly end is joined
It is merged and is connected into right angle, described curtain frame assembly is right-angled trapezium hollow frame structure, described right-angled trapezium acute angle is 17 degree, and it is vertical
Medial surface and long side bottom surface are provided with the slot coordinating with connector, and described connector both sides insert in adjacent curtain frame assembly respectively
In corresponding slot, adjacent curtain frame assembly end is connected, on described connector and curtain frame assembly, correspondence opens up the company of being equipped with
Connect hole, described connection in the hole setting connection fixture is connected.
Preferably, curtain frame assembly is aluminum component, connector is steel plate.Using double-decker, thus considerably increasing an act frame
Heavy burden ability, effectively prevent act frame from deforming because of carrying.
Preferably, curtain frame assembly is provided with screw, by the draw curtain bar on DLP casing, curtain frame is fixed on casing.
Described curtain frame coupling assembly comprises side coupling assembly and bottom coupling assembly, using 90 degree of bending techniques.
Described curtain frame assembly termination is provided with screw, matches with the screw in curtain frame coupling assembly, is connected by curtain frame
Assembly is spliced, and constitutes square screen frame.
Described curtain frame coupling assembly adopts steel plate or Metal plate, prevents act frame assembly stitching portion from becoming because being squeezed
Shape.
Described connection fixture is a kind of rivet, is entered between curtain frame assembly and curtain frame coupling assembly by the way of staking
Row is fixed.
Set slot inside described curtain frame assembly, match with curtain frame coupling assembly, the fixing curtain frame of the personnel that are easily installed is even
Connected components.
Beneficial effects of the present invention：1）Curtain frame assembly adopts a kind of aluminum material, lightweight, is easily installed.2）Curtain frame group
Part adopts double-decker, increases curtain frame bearing capacity, prevents from deforming.3）The curtain every Rotating fields of frame assembly are designed with reinforcement, thus
Considerably increase the heavy burden of act frame, effectively prevent act frame from deforming because of carrying.4）The coupling assembly of curtain frame adopts steel plate or metal plate
Golden material, increases the tautness of junction.
