Abstract

The utility model relates to an encrypted password padlock which is characterized in that: more than two anti-rotation bosses are punched on a padlock hook; more than two anti-rotation slots are arranged on an inner ring of a rotary core of the padlock; the bottom part of the rotary core is also provided with a rotary core spring, an E-shaped washer and a padlock hook spring; when a password of the padlock is incorrect, the padlock hook can be tightened so that a letter disc cannot rotate; moreover, an outsider cannot try out the password for unlocking the padlock; therefore, the safety and the anti-theft effect of the password padlock are enhanced.

Description

The ciphering type cipher hang lock

Technical field

The utility model relates to a kind of lockset, particularly a kind of ciphering type cipher hang lock.

Background technology

Lock is a kind of requisite antitheft, security personnel's instrument in people's daily life.That locks is of a great variety, wants key to open lockset but all be unable to do without, and one family has five, six keys usually, a working clan, and it also is common phenomena that waist is hung a big claw spoon, once lose a string key, will bring great inconvenience to live and work.The appearance of cipher hang lock has then solved above-mentioned problem, as long as remember the password of padlock, just can exempt the trouble of carrying key.Along with the raising of the science and technology development and the wisdom of humanity, some, robber particularly, utilize some existing defectives of cipher hang lock, unexpectedly can not destroy under the preceding topic of cipher hang lock, the letter disk in the rotation lock one by one is when letter disk forwards correct password to, because the boss that changes in the core snaps in the groove of shell, latch hook has obviously loosening sensation, thereby can rotate letter disk one by one, tries out the password of whole lock, padlock is opened, made cipher hang lock lose antitheft and safe effect.

Summary of the invention

The purpose of this utility model provides a kind of after locking, if the tension latch hook, during as if password bad, letter disk then can not rotate, thereby can not try out the ciphering type cipher hang lock of unlocking cipher.The utility model is realized in such a way; A kind of ciphering type cipher hang lock, comprise latch hook, E shape meson, commentaries on classics core, shell, copper plug, letter disk, lock pearl, lock pearl spring, it is characterized in that having on the latch hook anti-rotation boss more than 2, the interior ring that changes core has the anti-rotation groove more than 2, and the bottom of the commentaries on classics core of below has one to change core spring and " E " shape meson and a latch hook spring.During use, after the padlock locking, and during password bad, the boss and the shell groove that change on the core stagger, and change under the interaction of core lowermost " E " shape meson and commentaries on classics core spring, flick certain clearance, at this moment the anti-rotation boss on the latch hook does not also snap in the anti-rotation groove that changes in-core, changeing core can left-right rotation, thereby it is also rotatable to change the outer letter disk of core, can not influence the normal use of padlock; When password bad, the tension latch hook, under the situation that the commentaries on classics core can not move up and down, the core spring is changeed in " E " shape meson compression that latch hook drive to change under the core, and when " E " shape meson and lowermost commentaries on classics core clung to no gap, the anti-rotation boss on the latch hook just snapped in the anti-rotation groove of commentaries on classics in-core, the commentaries on classics core can not be rotated, at this moment change the outer letter disk of core and can not rotate thereupon, the stranger can not try out password, and padlock is safety and sound.The latch hook spring does not influence padlock and uses when just using lock always, and the back latch hook of unblanking is as forwarding 180 degree to, and under the effect of latch hook spring, latch hook can freely not fall, and the user can not change by mistake password; When needs changed password, the user must firmly depress latch hook, can revise password.

The utlity model has simple in structure, high safety, padlock when password bad, the tension latch hook, letter disk can not be rotated, thereby has strengthened the confidentiality and the safety of padlock.

Below in conjunction with accompanying drawing enforcement of the present utility model is described in further detail.
