Description

Technical Field

[0001] This utility model relates to a door lock. Background Technology

[0002] Chinese utility model patent CN223281874U discloses a magnetic door lock, including a housing, a bolt, an unlocking mechanism, and a lock groove. The bolt is rotatably disposed within the housing, and the housing has a bolt hole corresponding to the bolt's tongue end. The lock groove is disposed outside the housing, and the bolt magnetically engages with the tongue end within the lock groove to achieve magnetic locking. The unlocking mechanism includes a rotor, a lever, and a return torsion spring. The two ends of the rotor rotatably engage with the housing. The lever is sleeved on the outer circumference of the rotor and drives with the rotor. One end of the lever has a lever arm for contacting the bolt's tongue root end. The return torsion spring is circular and sleeved on the rotor. The spring wire of the return torsion spring has locking feet at both ends, which abut against the lever and the housing respectively to provide a force to drive the lever arm away from the tongue root end. The above-mentioned door lock has many lock body parts, a complex structure, and is troublesome to assemble. Utility Model Content
