Cam connection fastener and method of use thereof

Abstract

The invention discloses a cam connection fastener and a using method thereof and belongs to the field of machines. The cam connection fastener comprises embedded colloid particles, a connection rod, a base, a cam and a cam handle; one end of the connection rod is a hook-shaped part, and the other end of the connection rod is connected with the embedded colloid particles through threads; the bottom of the base is a round plate which is provided with an arc-shaped vertical plate fitted with the outer circumference of the round plate; the inner side of the arc-shaped vertical plate is provided with a vertical plate plane; the position of the center of the vertical plate plane is provided with an opening groove extending to the round plate; the cam is of a hollow structure; the two ends of the cam are provided with a hinging pin hinged to the handle and a connection pin connected with the hook-shaped part of the connection rod; and the position, close to the hinging pin, of the cam is provided with a contact plane fitted with the vertical plate plane of the arc-shaped vertical plate. The cam connection fastener is simple in structure and production process, high in efficiency, low in cost and high in strength, no gimlets need to be used in the connection fastening process, and the connecting and disassembling efficiency is high.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a cam connection fastener and a method for using the same. Background technique [0002] The three-in-one connector is composed of an eccentric wheel, a connecting rod and anti-skid pre-embedded rubber particles. It is mainly used for the connection of panel furniture, especially the vertical connection between panels of panel furniture. The connection between the two panels can be realized without screws. Horizontal connections, as well as three-board cross connections, are generally used for MDF, HDF, and particleboard. Among them, the eccentric wheel is the most important connecting accessory. Specifically, the radian of the torsion angle at the bottom of the eccentric wheel is deviated from the center of the circle. When the Phillips screw groove of the eccentric wheel is rotated through the screw cone, the connecting rod stuck in the radian will be pulled to the center ...

AI Technical Summary

Problems solved by technology

[0003] When the corkscrew rotates the cross groove of the eccentric wheel, the connecting plate drives the body of the eccentric wheel to rotate. Because the torque on the eccentric wheel is large and uneven, it is easy to cause the eccentric wheel to break

The eccentric wheel of the three-in-one connector used in the market has a complex structure, mainly made of zinc alloy and die-casting process, which has always had insufficient strength and low service life, and the steel mold die-casting process has high requirements for molds , leading to complex manufacturing process, which affects manufacturing efficiency and production cost
