Energy-saving magnetic lock with buffering function

Abstract

The invention relates to the related technical field of electric control door locks, and discloses an energy-saving magnetic lock with a buffer function. The lock comprises a fixed frame and a metal block; a silicon steel sheet is fixedly arranged on one side of the fixed frame; a timing switch connected through a wire is arranged on the silicon steel sheet. According to the energy-saving magneticlock with the buffering function, a movable frame, a conical blocking block and a detection switch are movably installed on the fixed frame, so that in the door closing process, a buffer block on themetal block slides on the movable frame to conduct first-stage speed reduction, meanwhile, the buffer block extrudes airflow in the pressure relief cavity of the fixed frame to flow out of a long andthin pressure relief hole, and therefore, second-stage speed reduction is realized; in the process that the pressure relief cavity in the fixed frame extrudes the conical blocking block, the detection switch is triggered to enable the silicon steel sheet not to be powered on any more, then when the metal block gets close to the silicon steel sheet, magnetic attraction force cannot be generated for acceleration, and the phenomenon of violent impact caused by rapid closing of a door is avoided; and finally, the door has a buffering function in the closing process.

Description

technical field [0001] The invention relates to the related technical field of electric-controlled door locks, in particular to an energy-saving magnetic lock with a buffer function. Background technique [0002] Magnetic locks, also known as access locks, are mainly used in residential areas, office buildings, shopping malls and other places in life, and have the ability to control user access, facilitate the entry of internal employees and prevent the random entry of outsiders, which not only facilitates internal management, but also enhances Internal security, so as to provide users with a stable environment. [0003] The main working principle of the existing magnetic lock is: by energizing the silicon steel sheet, and then the current passes through the silicon steel sheet to generate a magnetic attraction, so that the magnetic force will attract the metal block installed on the door to the silicon steel sheet. The switch button and the access control card reader turn ...
