Door lock

Abstract

The invention discloses a door lock which comprises a door frame and a door body. A frame cavity in front and back communication is formed in the door frame, and the door body is mounted on the rightend wall of the frame cavity. A positioning groove in communication with the frame cavity and with a forward opening is formed in the left end wall of the frame cavity. A positioning bar matched withthe positioning groove is arranged on the left end face of the door body. An electronic lock is installed at the left end of the door body, and a lock groove matched with a lock head of the electroniclock is formed in the left end wall of the frame cavity. A swing cavity is arranged on the left side of the positioning groove, and a first sliding groove and a second sliding groove communicating with the positioning groove are formed in the left end and the right end of the swing cavity correspondingly. A first conductive arm and a sliding block are mounted in the first sliding groove and the second sliding groove correspondingly in a sliding mode. A first oblique face is arranged at the right end of the sliding block, and a swing rod is arranged in the swing cavity. A rectangular groove inup and down communication is formed in the swing rod, and a telescopic rod in up-down symmetry is mounted in the rectangular groove in a sliding mode.

Description

technical field [0001] The invention relates to the field of living and home furnishing, in particular to a door lock. Background technique [0002] Electronic combination lock is an electronic product that controls the circuit or chip work (access control system) through password input, thereby controlling the closing of the mechanical switch and completing the tasks of unlocking and locking. There are many types of electronic products, including simple circuit products and Chip-based cost-effective products. Now the widely used electronic combination lock is based on the chip as the core and realized by programming. In the field of security technology prevention, the electronic combination lock with anti-theft alarm function replaces the traditional mechanical combination lock and overcomes the mechanical combination lock. The shortcomings of less passwords and poor security performance have greatly improved the combination lock both technically and in terms of performanc...

Problems solved by technology

Now the widely used electronic combination lock is based on the chip as the core and realized by programming. In the field of security technology prevention, the electronic combination lock with anti-theft alarm function replaces the traditional mechanical combination lock and overcomes the mechanical combination lock. The shortcomings of less passwords and poor security performance have greatly improved the combination lock both technically and in terms of performance. Traditional electronic locks need dry batteries to supply power, and dry batteries will continue to reduce power during the continuous use of electronic locks. Although the existing electronic lock has a reminder when the dry battery is low, and after the reminder, the electronic lock can be used many times, but some people still have a fluke mentality and are too lazy to replace the battery, or forget to replace the dry battery. Therefore, after the dry battery is exhausted, the door cannot be opened from the outside, and only professional personnel can be asked to remove and change the lock, which not only wastes time and energy, but also causes economic losses
