Abstract

The invention relates to a combined narrow-edge framework device. The combined narrow-edge framework device comprises a main framework, an external decoration rack and a plurality of elastic components, wherein the main framework is a rectangular framework mainly comprising two transverse frame rods and two longitudinal frame rods which are combined with four L-shaped angle connectors and a plurality of screws, the external decoration rack comprises two transverse decoration rods and two longitudinal decoration rods and is fixed at an outer side of the main framework by a plurality of screws,the main framework is used for supporting a projection screen, tension forces are provided for a surrounding edge of the projection screen by a plurality of elastic components hidden between the mainframework and the external decoration frame, so that the projection screen is smoothly expanded. In the combined narrow-edge framework device, the composite structure formed by combining the main framework and the external decoration framework has favorable mechanical strength, the width of the framework can be appropriately reduced to show a narrow-frame shape, and the problems that the projection screen framework device with a rough and wide framework is excessively large in wide, is heavy and is poor in attractiveness are solved.

Description

technical field [0001] The invention relates to a combined narrow frame device for installing a projection screen to form a projection screen. Background technique [0002] With the vigorous development of the optoelectronic industry, the method of projecting and displaying images through projectors has been widely used by the public. When a projector is used to display images, a projection screen is usually used as a medium for image projection and display. Therefore, the projection screen that provides image projection will also affect the presentation effect of the image. Based on the consideration of material and convenient storage, the existing projection screen is made of soft material, and an auxiliary projection screen frame device must be used to keep the projection screen in a uniform and flat state in order to maintain better image quality. [0003] Generally, the traditional projection screen frame device can only make a frame of a specific size according to the...
