Description

Sealed lid auto-lock structure based on electromagnetism adsorbs principle

Technical Field

The utility model relates to a from locking structure specifically is a sealed lid from locking structure based on electromagnetism adsorbs principle.

Background

The self-locking phenomenon means that if the action line of the resultant force Q of the main force acting on the object is within the friction angle, no matter how large the force is, a full reaction force R is balanced with the force, and the object is kept still.

Conversely, if the line of action of the resultant force Q of the active forces is outside the friction angle, the object may not be balanced no matter how small this force is. This equilibrium condition, independent of the magnitude of the force and dependent on the friction angle, is called a self-locking condition. The phenomenon of the object balancing under such conditions is called self-locking. The resultant force R of the normal reaction force N and the friction force F of the friction angle and the self-locking phenomenon is called the full reaction force of the support surface to the object. I.e. the friction force F reaches a maximum value Fmax, the included angle a also reaches a maximum value b, which is called the friction angle.

The aforesaid is the phenomenon of friction auto-lock, and current when carrying out the part auto-lock, generally adopt bayonet lock and draw-in groove complex mode fixed, but what mostly adopted when fixed is that the elastic component realizes the position and interferes, but the elastic component produces deformation easily and leads to elasticity to change after long-time the use, and when elasticity diminishes, fixed position produces easily and rocks, and is fixed insecure.
