Abstract
The utility model relates to a theft-proof code door lock. The utility model is characterized in that the utility model is provided with a code mechanism, and a baffle plate is arranged on a cylinder tongue integration; a code disk with a groove is used in the code mechanism, and a cylinder tongue top rod which is composed of a curved rod and a straight rod in a segment mode is arranged between the code disk and the baffle plate; a pressing spring sheet of the curved rod is fixedly connected to a pressing rod, and the other end of the pressing rod is abutted on a pushing tongue plate of the cylinder tongue integration; a long shifting fork is additionally arranged on an indoor lock hole, a shifting fork curved rod is correspondingly arranged, and the other end of the shifting fork curved rod is abutted on a straight rod. The utility model can opened in double faces. Because the code and a key are simultaneously needed in the outdoor unlocking, the safe reliability of the door lock is enhanced. When the door is unlocked indoors, the set of the code is ineffective, and the operation is convenient.
Description
The utility model relates to lock.More particularly, be the safe-guard door lock that a kind of key and password combine.
In the prior art, the combination type theftproof lock is widely used on the safety cabinet.Owing on its structure, only be unidirectional unlatching, therefore, can't be applicable to door lock.In addition, this coded lock is for experienced operator, and the feel and the sound in the time of can be by rotating disk come brokenly to select password, thereby insurance function is unreliable.
The purpose of this utility model is, avoids above-mentioned weak point of the prior art, provides a kind of insurance function reliable, code type security door lock that can two-sided unlatching.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises lock box, is arranged on the whole and oblique tongue integral body of post tongue in the lock box.
Design feature of the present utility model is that Cipher mechanism is set, and at the post tongue plate washer is set on the whole;
A, described Cipher mechanism adopt the combination disk that has groove, between described combination disk and plate washer, post tongue push rod are set, and described post tongue push rod constitutes by the curved bar that can insert the combination disk groove with in order to the straight-bar segmentation of supporting the shelves plate washer; The curved bar making leaf spring is set, and the curved bar making leaf spring connects firmly on depression bar, and the depression bar other end is pressed against pushing away on the hyoplastron of post tongue integral body by return spring;
B, increase on indoor lockhole long fork is set, and the corresponding fork curved bar that is provided with is arranged, the other end of fork curved bar is against on the straight-bar.
The utlity model has following advantage:
1, the utlity model has two-sided open function,, need grasp password and key simultaneously, improved the safety reliability of door lock greatly for unblanking outdoors.And when indoor key unlocking, password setting is inoperative, directly door can be opened, the convenient use.
2, the utility model is after door-lock opening, and the password knob can arbitrarily rotate.Can avoid on the one hand damaging the lock inner part, be divulged a secret with the password that prevents to have set on the other hand at the turning knob of exerting oneself outdoors.
3, the utility model is firmly unblanked with this lock key when the input password bad, because rotation password knob does not have feel, also has no abnormal sound, and the Cipher safety function is strong.
4, password adjustment of the present utility model can be finished at any time indoor, does not need to open lock box.
Accompanying drawing is the utility model structural representation.
By the following examples, in conjunction with the accompanying drawings the utility model is further described
Embodiment:
Referring to accompanying drawing, identical with prior art is that present embodiment comprises lock box 1 equally, is arranged on post tongue whole 2 and oblique tongue integral body 3 in the lock box 1.Different is Cipher mechanism to be set in the present embodiment, and on post tongue integral body 1 plate washer 4 to be set;
As shown in the figure, Cipher mechanism adopts the combination disk 6 that has groove 5, between combination disk 6 and plate washer 7, post tongue push rod is set, and post tongue push rod constitutes by the curved bar 8 that can insert combination disk groove 5 with in order to straight-bar 9 segmentations of supporting shelves plate washer 4; Curved bar making leaf spring 10 is set, and curved bar making leaf spring 10 connects firmly on depression bar 11, and depression bar 11 other ends are pressed against pushing away on the hyoplastron 12 of post tongue integral body by return spring;
Identical with door lock in the prior art is on indoor lockhole and outdoor lockhole, all is provided with respectively to pull out the short fork of tongue.In the present embodiment, on indoor lockhole 16, pull out the short fork 7 of tongue except original, increase is provided with long fork 13, and the corresponding fork curved bar 14 that is provided with is arranged, and the other end of fork curved bar 14 is against on the straight-bar 9, the bottom of fork curved bar 14 is provided with pole 17, in order to support fork curved bar 14.
Working condition is as follows:
Indoor unblanking:
Insert key from indoor lockhole 16, along with the rotation of key, long fork 13 is stirred fork curved bar 14, the other end of fork curved bar 14 lifts straight-bar 9, and baffle plate 4 is not stopped that in fallback procedures Cipher mechanism is inoperative, pull out the short fork 7 of tongue and can pull out tongue smoothly, finish and unblank.
Proper password, outdoor unblanking:
At first, by correct digital rotational password knob, make the groove 5 of each combination disk 6 corresponding consistent, key inserts from outdoor lockhole, rotation along with key, push away hyoplastron 12 and be lifted, depression bar 11 inserts in the combination disk groove 5, simultaneously the rod end of curved bar 8 by curved bar making leaf spring 10, the other end of curved bar 8 lifts straight-bar 9, retreating of 9 pairs of baffle plates of straight-bar do not stopped, at this moment, promptly removed the locking of Cipher mechanism.Being rotated further key just can unblank smoothly.
Bad password, outdoor unblanking:
Because the groove 5 of each combination disk 6 does not have corresponding to a position, the rod end of curved bar 8 can not press down, straight-bar 9 keeps motionless, at this moment, owing to do not have long fork on the outdoor lockhole, inoperative to fork curved bar 14, to such an extent as to it is also inoperative to straight-bar 9, retreating of plate washer 4 is subjected to stopping of straight-bar, causes key to rotate, and remains on lock-out state.Because the elastic force of curved bar making leaf spring 10, this moment the rotational password knob, feel easily, no unusual fluctuation, have no abnormal sound.
Lock under the open mode falls and is back to original height owing to push away hyoplastron 12, and the curved bar making leaf spring 10 of depression bar 11 ends lifts, and curved bar 8 rod ends lift under the effect of return spring thereupon.At this moment, because combination disk 6 is not subjected to any pressure, the password knob can freely rotate arbitrarily.
In the present embodiment, the dead bolt extension elongation is not subjected to the restriction of the combination disk groove depth.
