Description

A self-resetting locking device

technical field

The utility model relates to the technical field of automatic locking, in particular to an automatic reset locking device. the

Background technique

Most of the existing locking mechanisms are driven by electricity as kinetic energy. Once the electric energy disappears, they will not work. Others have a purely mechanical structure, but most of them are inconvenient to lock, or have complex structures, or poor firmness, or poor stability. and other shortcomings. the

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a compact, purely mechanical locking device with an automatic reset function. the

In order to achieve the above purpose, the technical solution provided by the utility model is: an automatic reset locking device, which includes a fixed seat, a button, a button spring, and a plug, wherein a counterbore chute is provided in the fixed seat, and the sinking There is a plug spring at the bottom of the hole chute. One end of the plug spring is in conflict with the bottom surface of the counterbore chute, and the other end is in conflict with one end of the plug assembled in the counterbore chute. The other end of the plug extends to the outside of the fixing seat to form a There is a slider groove in the middle of the plug, and the side wall of the slider groove located on the side of the plug spring is an inclined side wall; there is also a slider in the fixed seat, one end of the slider is located in the slider groove, and the end of the slider There is an inclined wall opposite to the inclined side wall of the slider groove, and the other end of the slider is provided with a bolt withdrawal groove, and the side wall of the bolt withdrawal groove on the side of the plug is an inclined side wall; the button is installed in the fixed seat through the button spring, One end extends into the bolt-removing groove, and the end is provided with an inclined wall opposite to the inclined side wall of the bolt-removing groove. the

After the utility model adopts the above scheme, when the button is pressed, the inclined front of one end stretches out, and the bolt-removing groove is pressed to move to the side of the bolt, and the bolt is withdrawn through the bolt-removing groove to realize unlocking. When the button is released , under the pressure of the plug spring, the locking device resets. The utility model has simple structure and strong practicability. the
