Technical Field

The application relates to a stationery commodity, especially relates to an adjustable frame of concatenation formula.

Background

The picture frame is a mosaic device designed for protecting and displaying pictures and enhancing the expressive power thereof. The structure is generally formed by assembling four side frames so as to be convenient for assembling paintings. In order to show or protect paintings, all the conventional picture frames are customized and can only be used once. At present, paintings are frequently shown and shown in irregular periods, and the paintings to be shown by exhibition institutions, artists and collectives are different in specification and size. The frame customization and the massive frame ordering of drawing a frame inevitably bring the waste of manpower, material resources and money, have brought the lasting destruction of trees forest more. This is not suitable for the environmental protection policy currently being pursued.

The Chinese utility model patent 'an oil painting frame', application (patent) No.: CN201320251460.2, in order to solve and to save raw and other materials and the processing cost and because the inconvenient technical problem who makes of frame size when oil painting frame adds man-hour, provide an oil painting frame of mutual concatenation, including horizontal ribbon pole and the vertical ribbon pole that two parallels of each other clamped, set up the tongue-and-groove at the both ends of ribbon pole respectively, the tongue-and-groove that matches each other through adjacent ribbon pole matches the gomphosis each other and clamps and form oil painting frame, has seted up the fastening groove at the rear of tongue-and-groove, for making the frame structure more firm, has the voussoir in the interpolation of fastening groove, the utility model discloses simple structure, the reliability is high, combines closely, great processing cost and the raw and other materials of having saved the enterprise.

Patent information service platform has also disclosed "a can dismantle two-sided frame", and application (patent) No.: CN201410080178.1, including side frame plate, embedded double-sided transparent panel and cavity for placing drawing board, also equipped with right angle connector, the side frame plates are connected and detachable through right angle connector, the connection of the side frame plate and right angle connector is equipped with empty bag, the right angle connector is inserted into empty bag, the side frame plate and right angle connector are also equipped with screw hole, and fixed connected through screw; the size of the side frame plate and the double-sided transparent panel can be adjusted and combined according to requirements. The picture frame disclosed by the invention can be used on two sides, the whole picture frame does not need to be moved and transported in advance, the picture frame can be disassembled into a plurality of frame strips for transportation, not only is the space saved, but also the picture frame can be assembled at any time according to the specification and the size of the picture panel, and the picture frame is fixedly connected through the connecting piece, so that the picture frame is strong in practicability, good in effect, convenient and quick.

However, the two applications only provide the splicing and installation of the frame strips at the corners, and have the following problems: 1. if different sizes of paintings are to be mounted, it is necessary to provide frame strips of different lengths. The frame strips with different lengths also need to be customized according to the pictures with different sizes, so that the frame strips still cannot be used universally, and the frame strips cannot be reused. 2. Only the splicing of the rectangular frame of the picture frame is disclosed, but in fact a picture frame should include a base or the like to assist in the tiling of the picture. The above disclosure does not constitute a complete picture frame for different sizes.

The technical scheme adopted by the application is as follows: the splicing type adjustable picture frame comprises a frame and a back plate,

the frame comprises a plurality of frame edges and frame corners;

the frame corner is used for connecting two frame edges which are positioned on a straight line or two frame edges which are vertical to each other;

the frame edge is detachably connected with the frame edge or the frame corner;

the back plate comprises at least one rectangular substrate, and any side of the substrate can be connected with another substrate;

the painting is laid on the surface of the back plate, and the frame is wrapped on the periphery of the back plate.

Compared with the prior art, the back plate structure has the advantages that the back plate structure is arranged at first and is used for supporting painting. When mounting paintings, the paintings are flatly laid on the back plate, and the frame is assembled and wrapped on the periphery of the back plate, namely the periphery of the paintings. Specifically, the back plate comprises at least one rectangular substrate, and the substrates are basic units spliced into the back plate.
