Description

Magnetic card coding lock with transverse slot

The utility model relates to a kind of horizontal magnetic card cipher hang lock of opening, and belongs to field of lockset.

Existing padlock mostly is spring padlock, and limited because of the pellet shot from a slingshot number, the tooth number variable quantity of key is few, and easily joins, easily distinguishes, causes cylinder lock mutual opening rate height, the deficiency of safety, confidentiality difference.Be applied in the high-grade single, double flapper lock on the door, used the magnetic pin lock core, because of it has password capacity big (not repeating up to 16,400,000,000 groups), the characteristics that password does not expose, so its safety, confidentiality are big, but because the lock core of door has part to expose, fastness is poor, install restrictedly, be not suitable for some places that need lockings security personnel (as the gate and the warehouse of resident's external door, office, school, hotel, factory).

The purpose of this utility model is, utilizes the spring padlock applicability strong, and intensity is big, and is survivable big with the magnetic pin capacity, is difficult for repeating, and password the moon covers, and is difficult for the characteristics of imitation, designs the horizontal magnetic card cipher hang lock of opening a kind of easy to use, safe and reliable.

Technical solution of the present utility model is.It has lock body 6, Magnetic lockwork 23, locking bolt 16, capping 15 and stage clip 14,22, and its special character is, establishes lock core box 5 in the bottom of Magnetic lockwork 23, and it makes Magnetic lockwork 23 is an integral body, forms movingly with lock body.Shift fork 4 is established at the back side of described lock core box 5, and its end is fixed on the lock body by bearing pin, and the other end touches mutually with the middle part of locking bolt 16, establishes drive pin 24 on the lock core body 2, and it touches mutually with the upper surface of shift fork 4.

The head end of the technical program shift fork 4 is established the pressing plate 25 of fixedlying connected with it.

Chimb 26 is established on the top of the technical program capping 15 1 ends, and an inclined-plane is established on other end top, and chimb 27 is established in the bottom.

The technical program, described Magnetic lockwork 23 is the variable magnetic cipher lock, can design two groups of above cipher keys like this, and is easy to use.

In the magnetic core box of the technical program, intubate 7 is established in the upper end of lock core body 2, establishes stage clip 8 in the intubate 7, and the exposed junction of stage clip 8 touches mutually with lock core body 2.

Because the utility model is established the shift fork that touches mutually with locking bolt in padlock, establish drive pin on the lock core body, establish lock core box on the Magnetic lockwork, reached lock core and lock body movingly, make Magnetic lockwork can be applied on the padlock, compared with prior art, have other people and can not copy key arbitrarily, the password capacity is big, repeatability is little, security performance is good, and survivability is strong, advantage applied widely.

The utility model is described in further detail below in conjunction with accompanying drawing.

The outer likeness in form of Magnetic lockwork of the present utility model is oval, and upwards successively by lock core box 5, lock core body 2 is positioned at the magnetic post of lock core body, jam plate 12, cover plate 11, backplate 10 formations from the bottom.Establish a plurality of holes in the lock core body, be used to hold the magnetic posts of password effect.The shape of set lock core box is seen Fig. 3, Fig. 4.It is made of a base and two sides.A slot is established at the middle part, base, and two grooves of symmetry are arranged at the bottom, and there is a hole at two grooves middle part, and this special construction is in order on the interior diapire that is stuck in lock body, and dual-side is set as boss shape, and in order to same jam plate, cover plate is fixed as one.Intubate 7 and lock core body 2 are working of plastics, and the two all is located in the lock core box, and link to each other by stage clip 8, and drive pin 24 is established in the lock core body bottom, in order to the motion of shift fork 4.The head end of shift fork is established pressing plate 25, and its end is fixed on the lock body 6 by bearing pin 3.Establish two garble wheels in the lock core body, form the variable cipher lock core, four kinds of passwords of conversion automatically are so can be equipped with four groups of cipher keys.Lock core box makes whole lock core form an integral body, forms movingly with lock body.The groove of two different depths is established at capping 15 middle parts, so that touch mutually with lock body and lock core are identical.A chimb is established on the top of its left end, so that be stuck in the groove of lock body; An inclined-plane is established on the top of its right-hand member, establishes the hole on the inclined-plane, and a chimb is established in the bottom, so that also be connected in conjunction with tight with lock body.Installation basic process is.At first stage clip 14 and locking bolt 16 are put into the hole of lock body, then shift fork 4 is connected with lock body by bearing pin 3, and allow the pressure board of head end in the groove of locking bolt, the lock core box 5 that is loaded with lock core body 2, jam plate 12, cover plate 11, backplate 10, intubate 7, stage clip 8, leaf spring 9 is put into lock core body, the lower end of lock body is put in capping 15, stage clip 22 and lock bridge 18 are fed in the hole of lock bodies, and capping 15 is fixed with silk post 17, limit a side of lock bridge 18, other side of lock bridge 18 limits with silk post 20.When magnetic card cipher lock dispatched from the factory, the password of input was as the number one password, and first, second, third and fourth number magnetic card key is a circulation group.Its operating principle is: the magnetic card key that will have the magnetic password inserts in the lock body opening, magnetic card password and lock core cipher acquaintance, the principle of repelling each other according to the magnetic same sex, key cipher and lock core cipher acquaintance, magnetic pin element-magnetic post withdraws from jam plate 12, be retracted into fully in the lock core body 2, be in opening, key 6 further inserts, and when lock core body moves forward, presses down shift fork 4 by drive pin 24, the pressing plate compression locking bolt 16 of shift fork 4 head ends, locking bolt 16 discharges lock bridge 18, and lock bridge 18 withdraws from lockhole under the effect of stage clip 22, and lock is opened.In the moment that lock is opened, lock select 16 is moving on the drive shift fork under the effect of stage clip 14, and shift fork impels lock core body 2 to retreat by drive pin 24, and while stage clip 8 also orders about lock core body 2 and retreats, and lock core body 2 is set back.When making lock be in locking states, enforce lock bridge 18, lock bridge 18 compression locking bolts 16, the head of locking bolt 16 enters in the groove of lock bridge, and at this moment, lock has been in locking states.When the number one key loss, when enabling No. second key operated lock, the number one password in the lock core is transformed into and No. second No. second identical password of key cipher automatically, and the number one key was lost efficacy, and the like.After a circulation group finishes,,, enter second circulation, but this possibility is very little can No. four key lost efficacy though the number one key reactivates.In case occur, can arrive producer and change lock core, to guarantee safety.

If not the variable cipher Magnetic lockwork, then have only one group of cipher key, in case lose, though common people can not be equipped with key, because of password can not be changed, so increased a unsafe factor.

If the end of shift fork 4 is not established a pressing plate separately, and makes its head-bent and do suitable processing, its lower surface with locking bolt 16 intermediate channel is touched mutually, also can reach the purpose of unblanking, but it is big to do its requirement of strength of material of shift fork 4.

If do not have intubate 7 and stage clip 8, after lock is opened, lock core body 2 is set back by stage clip 14, lock select 16, shift fork 4 and drive pin 24, but not as above embodiment recover flexibly.
