Problems solved by technology
Among them, the types of screw connection fixing anti-loosening and anti-slip are divided into frictional anti-loosening, mechanical anti-loosening and destroying the movement relationship of thread pairs. At present, frictional anti-loosening uses the most two methods of spring washers and primary and secondary nuts; mechanical anti-loosening includes: cotter pin and Channel nuts, round nut stop washers, hexagon nut stop washers, and series steel wires are four methods; there are two methods of anti-loosening by destroying thread pairs: punching, spot welding, and bonding. The existing mechanical anti-loosening methods need to be added Additional parts lead to increased cost, and the movement mode of the damaged thread pair is not easy to disassemble, and it cannot be recycled and reused

The invention discloses a connection structure, and particularly relates to a screw connection structure for electronic products. The screw connecting structure for the electronic products is needless of using additional parts and can achieve a good anti-sliding purpose. The screw connection structure for the electronic products comprises a screw, a thread hole connecting piece and a common connecting piece, a clearing hole is formed in the common connecting piece, a thread hole is formed in the thread hole connecting piece, the screw penetrates through the clearing hole and is connected to the thread hole so as to enable the thread hole connecting piece and the common connecting piece to be fixed with each other, and an anti-sliding protrusion is arranged at the position where the common connecting piece and the thread hole connecting piece are in contact with each other. Due to the fact that the anti-sliding protrusion is arranged at the contacting position of the common connecting piece and the thread hole connecting piece, when the common connecting piece and the thread hole connecting piece are attached to each other under the effect of the screw, and sufficient friction force can be generated between the common connecting piece and the thread hole connecting piece to prevent sliding. Thus, the additional parts are of no need, and the screw can achieve the purpose of being anti-sliding and anti-loose without the need for further technology processing.
Description
technical field [0001] The invention relates to a connection structure, in particular to a screw connection structure for electronic products. Background technique [0002] At present, the commonly used structural assembly and fixing methods of consumer electronic products include screw connection, as well as connection methods such as snap, bonding, and welding. Among them, the types of anti-loosening and anti-skid of screw connection are divided into friction anti-loosening, mechanical anti-loosening and destroying the motion relationship of the thread pair. At present, friction anti-loosening methods are mostly used in two ways: spring washers and main and auxiliary nuts; mechanical anti-loosening methods include: split pins and There are four ways of slotted nut, round nut stop washer, hexagonal nut stop washer, and series steel wire; there are two ways to prevent loose thread pair movement: punching, spot welding, and bonding. The existing mechanical anti-loosening meth...
