Description

A multifunctional card slot picture frame projection screen

technical field

The invention relates to the technical field of projection screens, in particular to a projection screen with a multifunctional card slot picture frame.

Background technique

The picture frame projection screen is composed of frame components to form a frame assembly, and the curtain is tightened by tension members located in the frame components. Figure 1 shows a common picture frame projection screen in the prior art. The tension member 1 in the picture frame projection screen One end is slidably embedded in the slot of the frame member 2, and the other end is connected to the edge of the screen 3, and the tension member 1 provides tension to tighten the screen 3, wherein the opening direction of the slot is parallel to the direction of the screen.

Patent CN 206470528U discloses an oblique tension invisible picture frame projection screen. Similarly, in the picture frame projection screen, the opening direction of the tension spring groove is also parallel to the direction of the screen. In the picture frame projection screen of this kind of structure, the tension spring clamping groove only plays a single role of fixing the tension spring, and has a single function; moreover, when adjacent frame components are connected by corner codes, it is necessary to additionally drill holes in the frame components , to complete the assembly between adjacent frame members, the installation is cumbersome, and the manufacturing cost is high.

Contents of the invention

The technical problem to be solved by the present invention is to provide a multifunctional picture frame projection screen with a compact structure and convenient installation.

The technical solution adopted to solve the above-mentioned technical problems: a multi-functional card-slot picture frame projection screen, including a screen frame assembled by frame members and a curtain on the inside or outside of the screen frame by tension members, the frame member The back side is provided with a draw-in groove whose opening direction is perpendicular to the curtain, one end of the tension member is connected to the draw-in groove, and the other end is connected to the edge of the curtain.

Further, both ends of the frame member have inclined splicing end faces, and adjacent frame members are joined by splicing end faces and connected to form a whole through corner brackets, and the ends of the corner brackets are plugged into the card in the adjacent frame member. The slot also includes a screw fastener threaded through the card slot and the corner code.

Further, it also includes a fixing member fixed on the wall, the fixing member extends outwards to form a connection end plate connected with the frame member, a fixing strip is embedded in the predetermined position of the card slot of the frame member, through The screw fastener passes through the connecting end plate, the card slot and is threadedly connected with the fixing bar, so that the frame member and the fixing member are connected to form an integral body.

Further, the top surface and back side of the frame member are concaved to form an arc-shaped end plate.

Beneficial effects: In this multi-functional card slot picture frame projection screen, the traditional card slot structure is abandoned, and the opening direction of the card slot is set to be perpendicular to the screen. The card slot can be suitable for matching such as single hook extension spring, double hook extension spring, Different tensile components such as hook nails and beading have wide applicability; moreover, the card slot can also serve as a connection through hole for the splicing combination of adjacent frame components, which does not require additional drilling, reduces costs, and makes the installation of the screen frame more efficient , easy.

Detailed ways

Referring to Fig. 2 to Fig. 5, the multi-function card slot picture frame projection screen of the present invention includes a screen frame assembled by four frame members 10 and a curtain 30 inside the screen frame by tension members 20, and the back side of the frame member 10 is There is a card slot 11 whose opening direction is perpendicular to the curtain 30, one end of the tension member 20 is embedded in the card slot 11, and can slide in the card slot 11, and the other end is connected with the edge of the screen through a tension rod, and the tension member 20 is along the screen frame. The slots 11 are evenly spaced, so as to provide a uniform pulling force to unfold and flatten the curtain 30 . Since the position and direction of the card slot 11 are set to be perpendicular to the curtain 30, the card slot 11 can be adapted to match different types of tension members 20, such as single-hook extension springs, double-hook extension springs, hook nails, press strips, etc. The selection type of the tension member 20 is not limited to a single-hook tension spring.

Of course, the curtain 30 can also be outside the screen frame by the tension member 20, that is, the curtain goes around the edge of the screen frame and is connected with the tension member on the back, so that the curtain is tightly positioned on the front side of the picture frame.

6 to 9, the frame members 10 are respectively two long frames and two end frames. They are all spliced end faces with an oblique angle of 45 degrees. The spliced end faces of adjacent frame members 10 are joined to form a right angle. The two ends of the corner code 40 are respectively inserted into the card slot 11, and the corresponding positions of the corner code 40 and the card slot 11 have screw holes. , through the screw fastener 50 through the card slot 11 and threaded connection with the screw hole of the corner code 40, so that the frame member 10 and the corner code 40 are tightly connected to form an integral body, when the traditional adjacent frame members are connected by the corner code, It is necessary to drill holes on the frame member to provide connection holes. In the present invention, the opening of the card slot 11 is perpendicular to the corner code 40, and the card slot 11 can serve as a connecting through hole for splicing and combining adjacent frame members 10 without additional drilling. Holes effectively reduce the cost, and also make the installation of the screen frame more efficient and convenient.

Among them, the curtain frame is fixed on the wall by four fixing members 60 up and down, left and right. The fixing member 60 is a bent sheet metal member with a U-shaped cross section. , the connecting end plate 63 is connected with the frame member 10, specifically, a fixing bar 64 is embedded at a position corresponding to the slot 11 of the frame member 10, and the fixing bar 64 is provided with a screw hole corresponding to the slot 11, The screw fastener 50 passes through the connecting end plate 63, the card slot 11 and the screw hole of the fixing bar 64 to be threaded, so that the frame member 10 and the fixing member 60 are connected to form one body, and the curtain frame is hung on the wall by means of the fixing member 60 superior.

The draw-in slot 11 in the multifunctional draw-in slot picture frame projection screen of the present invention is not only used as a slot where the tension member 20 is installed and fixed, but also as a connecting hole for assembling and joining between adjacent frame members 10 and a fixing hole that is connected with the fixing member 60. Holes have multiple functions.

Preferably, the top and back of the frame member 10 are concaved to form an arc-shaped end plate 12 , which makes the frame member 10 thinner visually, making the curtain frame fixed on the wall more beautiful and concise.

The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and can also be made without departing from the gist of the present invention within the scope of knowledge of those of ordinary skill in the art. Variations.
