Problems solved by technology

[0002] At present, the hinged positioning structure of the leg tube of common furniture is usually supported by a support hinge, which is composed of two pieces of metal. This support hinge has a shear point, which is easy to pinch hands during use, posing a safety hazard; there are also some furniture. The support tube is used for positioning and connection. This structure requires separate disassembly and fixed installation of the support tube during use, resulting in cumbersome operation and a lot of consumables.

Abstract

The invention relates to a hinge joint positioning device for a tube, and the hinge joint positioning device comprises a fixed base, an end cap, a spring, a sliding block, a hinge joint base and rivets. The hinge joint positioning device for the tube is characterized in that the spring is arranged between the sliding block and the end cap, the end cap is fixedly connected to the hinge joint base, the hinge joint base is hinged with the fixed base by virtue of the rivets, positioning support of the hinge joint base can be realized only requiring that the hinge joint base is arranged in a positioning slot on the fixed base; and when rotating and folding are required, the hinge joint base is pulled only, so that the rivets push the sliding block to compress the spring, the spring is compressed and shortened, the hinge joint base is separated from the positioning slot, and free rotating of the hinge joint base can be realized. Thus, the hinge joint positioning device for the tube provided by the invention has the advantages of simple structure, easiness operation and suitability for being used as an accessory for furniture.

Description

technical field [0001] The invention relates to a furniture accessory, in particular to a hinged positioning device for a leg tube. Background technique [0002] At present, the hinged positioning structure of the leg tube of common furniture is usually supported by a support hinge, which is composed of two pieces of metal. This support hinge has a shear point, which is easy to pinch hands during use, posing a safety hazard; there are also some furniture. The positioning and connection of the support tube is adopted. During the use of this structure, the support tube needs to be disassembled and fixed separately, resulting in a cumbersome operation process and a lot of consumables. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a hinged positioning device for the leg tube, which can simplify the structure, facilitate operation and eliminate potential safety hazards. [0004] The technical solution adopted ...
