And therefore, the diversity of angle change and movement can be improved.

Description

Technical Field

[0001] The utility model relates to the technical field of exhibition equipment design and manufacturing, in particular to a movable curtain for exhibitions. Background Art

[0002] Curtain, a large piece of cloth, velvet, etc. hung on the stage for performances or movie screenings. The one behind the stage is called the cyclorama, the ones on both sides of the stage are called side curtains. The one in front of the stage is called the main curtain or curtain.

[0003] The screen used for projection is called projection screen, which is one of the most commonly used products in projector peripheral equipment. If the projection screen is properly matched with the projector, you can get a high-quality projection effect. Projection screens can generally be divided into two types in terms of function: reflective and transmissive. The reflective type is used for front projection, and the transmissive type is used for rear projection. The front projection screen is divided into flat screen and curved screen. In terms of texture, it can be divided into glass screen, metal screen, embossed plastic screen, etc.

[0004] The screens in the prior art are mostly fixed on the wall or on a bracket when used in exhibitions. The screens fixed on the wall can only display in a single direction, which limits the exhibition display. In addition, the existing projectors have a certain angle adjustment, while the screens fixed on the wall cannot be moved and thus cannot be displayed at multiple angles. As a result, the projector lens cannot be aligned with the projection screen, causing the projection image to be deformed or tilted, which cannot meet normal usage requirements. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a movable screen for exhibitions, which has the effects of angle adjustment and synchronous swing with a projector.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a movable curtain for exhibitions includes a top casing, a curtain is movably connected to the edge of the lower surface of the top casing, a vertical rod is fixedly installed at one end of the curtain away from the top casing, and a movable angle component is fixedly installed in the middle of one side surface of the top casing;

[0007] The movable angle assembly includes an arc-shaped base fixedly installed in the middle of one side of the top casing, and limiting parts are provided on both sides of one side surface of the arc-shaped base. A connecting groove is opened on one side surface of the arc-shaped base near the limiting part, and a driving gear is movably connected to the inner top wall of the connecting groove, and one side of the driving gear is movably clamped in the connecting groove.

[0008] Optionally, the number of the limiting parts is four and they are evenly distributed in a rectangular array, and two of the four limiting parts form a group, and the lower surface of one group of the limiting parts is movably connected to a clamping wheel via a rotating shaft.

[0009] Optionally, a connecting portion is provided on one side of the outer arc surface of the snap-in wheel, the number of the snap-in wheels is four, and they are movably connected to one group of the limiting portions, and the outer arc surface of the snap-in wheel is movably snap-connected with an arc track component through the connecting portion.

[0010] Optionally, an outer arc surface of the arc track component is provided with an arc sawtooth bar, the arc sawtooth bar is connected and matched with the arc track component, and the outer arc surface of the arc sawtooth bar is matched with the driving gear.

[0011] Optionally, the serrations on the outer arc surface of the driving gear are meshedly connected to the arc track component, and fixing plates are fixedly installed on both sides of the arc track component.

[0012] Optionally, a fixing groove is provided on one side surface of the fixing plate, and the top casing is movably adapted to the arc track component. The surface of the limiting portion is movably clamped on the surface of the arc track component by moving the angle component. At the same time, the arc-shaped base is fixedly installed on the top casing. When the screen swings, the driving gear of the movable top casing will rotate so that it will swing on the meshing arc track component along with the meshing arc serrated bar, thereby avoiding only being able to display in a single direction, which makes the exhibition display have certain limitations, and the screen cannot be moved and cannot be displayed at multiple angles, resulting in the situation that the projector lens cannot be aligned with the projection screen, thereby improving the angle change and movement diversity.

[0013] The utility model provides a movable curtain for exhibition, which has the following beneficial effects:

[0014] By moving the angle component, the movable clamp on the surface of the limit part is connected to the surface of the arc track component, and the arc-shaped base is fixedly installed on the top casing. When the screen swings, the driving gear of the mobile top casing will rotate to make it swing on the meshing arc track component along with the meshing arc serrated bar, thereby avoiding the situation that only a single direction can be displayed, which makes the exhibition display have certain limitations, and the screen cannot be moved and cannot be displayed at multiple angles, resulting in the situation that the projector lens cannot be aligned with the projection screen, thereby improving the angle change and movement diversity.
