Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.

Embodiment one:

A kind of metal door door lock assembly, comprise power supply 1, lock core 2, the rotating lock tongue 3 of rotation is driven by described lock core 2, doorframe 4 is provided with the insulated fastener 5 buckled into for described rotating lock tongue 3, be arranged on the upper calutron 6 on doorframe 4 and lower calutron 7, described power supply 1 provides electric power for upper calutron 6 and lower calutron 7, described rotating lock tongue 3 is fixed on the rear portion of lock core 2, the external surface at lock core 2 rear portion is provided with and triggers sheet 8, rotating lock tongue 3 correspondence triggers rotation realization and the contact triggering the sheet 8 or trigger end 9 be separated that sheet 8 is provided with rotating lock tongue 3, described upper calutron 6 and lower calutron 7 by trigger end 9 with trigger contacting or separating the magnetic or relieving that realize opposite house body 10 of sheet 8.

For the door body 10 adapting to unlike material can use door lock assembly of the present utility model, thus improve applicability further, on corresponding described on door body 10, the position of calutron 6 and lower calutron 7 is fixedly installed magnetic iron block.

Also comprise for described upper calutron 6 and lower calutron 7 provide the backup battery of back-up source, avoid after power cut-off, upper calutron 6 and lower calutron 7 lost efficacy and caused the raising of risk.

Described upper calutron 6 and lower calutron 7, triggering sheet 8 and trigger end 9 are in series by wire 11.Concrete, be protruding contact surface 12 in the middle of described triggering sheet 8, the side of described triggering sheet 8 is recessed disengaging face 13, and opposite side is the joint 14 be connected with described wire 11.

Described upper calutron 6 and lower calutron 7 are upper magnetic key operated lock and lower magnetic force lock.Concrete, described upper magnetic key operated lock and lower magnetic force lock are fixed on doorframe 4 respectively by holder.

For avoiding being electrically communicated on a body 10 or doorframe 4, also comprise insulation holder 15, described lock core 2 is fixed on a body 10 by insulation holder 15, triggers sheet 8 and is fixedly connected on described insulation holder 15.

Described rotating lock tongue 3 is provided with the insulation connecting portion stretched out to lock core 2 side, and described trigger end 9 is fixedly connected on described insulation connecting portion.

The course of work of the present utility model and operating principle: during use, turn lock core by the key of correspondence thus drive rotating lock tongue to rotate 90 °, trigger end on rotating lock tongue contacts with triggering sheet, circuit turn-on, upper magnetic key operated lock and lower magnetic force lock the magnetic iron block held on a body, it should be noted that if door body material is can be made by the material of magnetic, then can not need to use magnetic iron block, upper magnetic key operated lock and lower magnetic force lock directly hold on door body, simultaneously, rotating lock tongue is buckled in insulated fastener after rotating 90 °, and now, door body is lockable; When unblanking, rotate backward 90 ° of trigger ends on rotating lock tongue and to slip away triggering sheet, now, circuit breaker, upper magnetic key operated lock and lower magnetic force lock loose opening door body, and meanwhile, rotating lock tongue produces from insulated fastener, and door body is unlocked.

When having a power failure, although upper magnetic key operated lock and lower magnetic force unlock, because rotating lock tongue is still buckled in insulated fastener, therefore door body remains and is lockable, and now beating opening door body and also only can need open with key, can not open because of having a power failure.

Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
