Abstract

The invention discloses an X type folding bracket. The X type folding bracket comprises a first supporting rod assembly and a second supporting rod assembly which are integrally shafted through a hinge pin; a height adjusting device is arranged at a part in which the first supporting rod assembly and the second supporting rod assembly are shafted. The X type folding bracket is characterized in that the height adjusting device comprises a first rotating plate, a second rotating plate and a fixed plate; an arc-shaped sliding groove is arranged in the fixed plate; an arc-shaped adjusting groove is arranged in the first rotating plate; an arc-shaped limiting groove in which a limiting block is arranged is formed in the second rotating plate; an adjusting pin and a limiting pin are fixedly arranged on the limiting block, wherein the adjusting pin passes through the arc-shaped adjusting groove, and while the limiting pin extends into the arc-shaped limiting groove; a positioning device is arranged at the end part of the adjusting pin. The X type folding bracket has the advantages that the use height of the X type folding bracket can be adjusted by adjusting the position of the limiting block in the arc-shaped sliding groove through the positioning device; in addition, the X type folding bracket can be folded without operating the positioning device, so that the use and adjusting are convenient.

Description

technical field [0001] The invention relates to a bracket structure, in particular to an x-shaped folding bracket. Background technique [0002] Because of its flexible height adjustment, the x-shaped folding bracket is convenient for the storage of the supporting structure after folding. It is usually used as a supporting frame structure and widely used in devices that need to be accessed and stored, such as piano frames, folding desk frames, or folding chairs. [0003] For example, the utility model announcement of Chinese Patent No. 201020026750.3 discloses a support structure for an electronic piano frame, which adopts the second support rod to be set as a rod body formed by connecting the upper rod body and the lower rod body through a positioning plate, and makes the rod body pass through the positioning plate It is hinged on the same plane with the first support rod, which makes the opening and closing of the piano frame and the adjustment of the use height more conve...
