Problems solved by technology
[0004] The problem with the eccentric connector is that the volume of the plug nut will change after long-term use, which will reduce the friction between the plug nut and the plate, the plug nut will come out of the plate, and the connection between the plug nut and the suspender Failure, resulting in the disappearance of the fastening and connection between the plates, and the connected plates are separated from each other

The invention relates to an elastic opening nut eccentric connecting piece. The elastic opening nut eccentric connecting piece is characterized in that the elastic opening nut eccentric connecting piece consists of an elastic opening nut 1, a hanging rod 2 and a cylindrical female plug 3, wherein the elastic opening nut 1 is loaded in an annular groove 6 formed in a plate 4 under a closed condition, and then relying on own elasticity of the nut, the elastic opening nut 1 is automatically opened; when the elastic opening nut 1 is stressed by the force which is in parallel to an axis of the elastic opening nut 1, acting force between the elastic opening nut 1 and the side wall of the annular groove 6 is generated, so that the elastic opening nut 1 is prevented from being deviated from a hole7; threads in one end of the hanging rod 2 is connected to the inner part of the elastic opening nut 1, and the other end of the hanging rod 2 is connected to a cam curved groove in the cylindrical female plug 3 through a middle through hole 8 and an end through hole 9 of the plate 5; and when the cylindrical female plug 3 is twisted clockwise, the hanging rod 2 is lifted in the cam curved groove, so that the vertical connection between the two components is realized. The key points of the elastic opening nut eccentric connecting piece disclosed by the invention lie in that friction between the elastic opening nut and a panel is replaced by mutual thrust, the situation that the position of the elastic opening nut in the annular groove is fixed is guaranteed, and the fastening effect and connecting effect between plates are guaranteed.
Description
technical field [0001] The invention relates to an eccentric connecting piece and belongs to the technical field of furniture. Background technique [0002] Furniture connectors generally refer to the parts that fasten and connect boards in the furniture production process, mainly referring to: eccentric connectors, screws, rivets, mother-in-law combination nuts, etc., while furniture connectors The most widely used is the eccentric connection. [0003] The eccentric connector is composed of a cylindrical plug nut, a suspender and a plug nut. One end of the suspender is threaded and can be connected to the plug nut, and the other end passes through the end hole of the plate and is connected to the cam curve. In the groove, when the cylindrical plug nut is turned clockwise, the boom is lifted in the cam curve groove, and the vertical connection between the two parts can be realized. [0004] The problem with the eccentric connector is that the volume of the plug nut will ch...
