Description of drawings
Fig. 1 is an internal construction principle schematic of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1, the utility model comprises oblique tongue 1, locating piece 2, resilient key 3, tail cover 4, tower spring 5, cover plate 6, lock body 7, shifting block 8, square core 9, outer plectrum 10, interior plectrum 11, backwash sheet 12, square tongue 13, tumbler 14, three ring springs 15, insurance chi 16, safety block 17, sword iron 18, unlocking board 19, rotational pin 20, straight line spring 21, spring steel ball 22, double-screw bolt 23, counnter attack rotating shaft pilot hole 24, turning cylinder 25 etc.Unlocking board 19 and backwash sheet 12 are loaded in the lock body 7 by turning cylinder 25, and an end of unlocking board 19 touches mutually with outer shifting block 10, and the other end touches mutually with tumbler 14; On unlocking board 19 and turning cylinder 25, be provided with straight line spring 21; On the rotational pin 20 of tumbler 14, be provided with three ring springs 15.One end of backwash sheet 12 touches mutually with interior plectrum 11, and the other end touches mutually with safety block 17; On safety block 17, be provided with spring steel ball 22.
During actual the use, indoor handle can be opened oblique tongue 1 and square tongue 13 simultaneously.Detailed process is as follows: press down handle, square core 9 rotates, and rotates thereby drive shifting block 8, and interior plectrum 11 also rotates; Can stir oblique tongue locating piece 2 when interior plectrum 11 rotates, regain oblique tongue 1, unlocking board 19 is rotated; When unlocking board 19 rotates, safety block 17 is rotated, the arming function also makes tumbler 14 rotate simultaneously, translation side's tongue 13, square tongue 13 under three ring springs, 15 effects on the tumbler 14, automatic drawing back after tumbler 14 rotates 45 °.Like this, can open oblique tongue 1 and square tongue 13 at the indoor handle of once depressing.
When in the priming chamber during safeties, outdoor can not be with key operated, but once move arming and opening the door during indoor unlatching.Detailed process is as follows: turn round in indoor rotation insurance, rotate safety block 17 by insurance chi 16, thereby backwash sheet 12 is rotated, and by unlocking board 19 side's of stirring tongues 13, tumbler 14 is rotated; Side's tongue 13 ejects when tumbler 14 rotates 45 ° under three ring springs, 15 effects on the tumbler 14 automatically.As rotate the insurance turn round 90 ° of location after, then safety block 17 is also corresponding has rotated 90 °.At this moment as will rotating tumblers 14 by the sword iron 18 of tapered end, dial back square tongue at outdoor unlatching side tongue 13, but square tongue 13 withstands backwash sheet 12, safety block 17 also withstands backwash sheet 12, and at this moment key can not the side's of unlatching tongue 13 on the chamber, has also just realized indoor insurance function.If safety block 17 returns original position behind the spring side of going out tongue 13, then outdoor key can unlatching side's tongue 13, and concrete principle is as follows: after insurance is turned round and got back to original position, safety block 17 resets, just can not push up a backwash sheet 12, backwash sheet 12 can not the side's of withstanding tongue 13, and then rotating tumbler 14 just can withdrawal side's tongue.That is to say have only outdoor in this case can be with key operated side's tongue 13.
