Specific embodiment
With reference to Fig. 2 to Fig. 5, the multi-functional card slot picture frame projection screen of the present invention, including assembling structure by four edge frame members 10
Into curtain frame and the curtain 30 on the inside of the curtain frame tensed by tension member 20, the back side of edge frame member 10 is equipped with opening direction
The card slot 11 perpendicular with curtain 30,20 one end of tension member are embedded in card slot 11, can be slided in card slot 11, the other end leads to
It crosses stayed mast with curtain edge to be connected, tension member 20 is evenly spaced on along the card slot 11 of curtain frame, so as to provide equably
Pulling force evens up the expansion of curtain 30.Since the position of card slot 11 and direction are arranged to perpendicular with curtain 30 so that 11 energy of card slot
It is enough to be applicable in the different types of tension member 20 of matching, such as single hook tension spring, Double-hook tension-spring, hook nail, press strip etc., greatly widen
The Selective type of tension member 20 is not limited only to single hook tension spring.
Certainly, curtain 30 is also in an act outer frame side by the tension of tension member 20, i.e., curtain around curtain frame edge and
The tension member at back is connected, and curtain is made to tense on front side of picture frame.
With reference to Fig. 6 to Fig. 9, edge frame member 10 is respectively two long margin frames and two end edge frames, adjacent edge frame member 10 it
Between docked by splice ends face and pass through corner brace 40 and be connected to form one, specifically, 10 both ends of edge frame member are 45 degree of oblique angles
Splicing end face, the splice ends face of adjacent edge frame member 10 docks to form right angle, and the both ends of corner brace 40 are inserted respectively into card slot 11
Interior, the corresponding position of corner brace 40 is corresponding with card slot 11 to have screw hole, is fixed by screw part 50 through card slot 11 and corner brace 40
Screw hole is threadedly coupled, and one is connected to form so as to which edge frame member 10 and corner brace 40 be pressed, and is led between the adjacent edge frame member of tradition
When crossing corner brace connection, it must drill in edge frame member and connecting hole position is provided, the opening of card slot 11 and corner brace 40 in the present invention
Perpendicular, card slot 11 can serve as the connection through hole spliced and combined as adjacent edge frame member 10, need not additionally drill, effectively
Ground reduces cost, but also the installation of curtain frame is highly efficient, easy.
Wherein, curtain frame is fixed on by four fixing components 60 up and down on wall, and fixing component 60 is bending metal plate
Component, section take the shape of the letter U, by fixed charge method end plate 61 connected vertically, fixed bottom plate 62 and connection end plate 63, connection end plate 63 and and side
Frame component 10 is connected, specifically, embedded with fixed strip 64, fixed strip 64 at 11 opposite position of card slot of edge frame member 10
Be equipped with 11 corresponding screw hole of card slot, be fixed by screw part 50 through connection end plate 63, the spiral shell of card slot 11 and fixed strip 64
Hole is threadedly coupled, and so as to which edge frame member 10 and fixing component 60 are connected to form one, is hung over curtain frame by fixing component 60
On wall.
Card slot 11 installs fixed slot position not only as tension member 20 in the multi-functional card slot picture frame projection screen of the present invention,
Also as the connecting hole position of assembling split between adjacent edge frame member 10 and the fixed hole position being connected with fixing component 60, tool
There are many functions.
Preferably, 10 top surface back side of edge frame member is recessed arc-shaped end plate 12, the setting of arc-shaped end plate 12 causes side
Frame component 10 is visually thinning so that the curtain frame being fixed on wall is more beautiful, succinct.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the invention is not restricted to above-mentioned embodiment party
Formula, can also be before present inventive concept not be departed from the knowledge possessed in the technical field those of ordinary skill
Put that various changes can be made.
