Description
Technical field
The invention belongs to button fields, and in particular to a kind of self-locking snap-fastener.
Background technique
Snap-fastener is made of pin thread and female thread, and being mutually twisted by pin thread and female thread, realizes the joint portions such as clothes, luggage
The engagement of position.
Existing snap-fastener is mainly fabricated by two kinds of materials of plastics or metal, and the snap-fastener manufactured using plastic material is needed
The high accuracy of manufacture is wanted come the engaging error caused by temperature difference when overcoming because of manufacture and circumstance of temperature difference between female thread and pin thread, is used
The snap-fastener of metal manufacture, though it can be reduced the engaging error that the temperature difference and circumstance of temperature difference generate when manufacture, it also requires relatively high
The accuracy of manufacture guarantees the normal use of snap-fastener.
The snap-fastener of two kinds of materials of above-mentioned plastics or metal manufacture, when fastening, are required to squeeze a part for making pin thread and female thread
It generates deformation to fasten to realize, the fastening of this sample loading mode easily makes snap-fastener because causing between female thread and pin thread caused by material abrasion
Engage error, undesirably falls off pin thread with female thread, will also result in fatigue of materials and follow the string, snap-fastener is made to cannot achieve fastening.
Summary of the invention
