Detailed description of the invention
Safety lock structure, as Figure 1-4, the keeper 21 comprising lock body 14 and match with lock body 14, locking bar 1 is provided with in lock body 14, dead bolt 7 and the Cipher mechanism 4 matched with locking bar 1, Cipher mechanism 4 comprises combination disk, gear mechanism and movable mechanism, the dead bolt slide rail 24 matched with dead bolt 7 is also provided with in lock body 14, the lockhole 22 matched with dead bolt 7 is provided with in keeper 21, dead bolt 7 top is provided with the locking bar through hole 17 matched with locking bar 1, the locking ball installing hole 25 be communicated with locking bar through hole 17 is vertically provided with in dead bolt 7, two locking balls 6 are vertically installed with in locking ball installing hole 25, locking bar 1 front portion is provided with the locking bar limited impression 5 matched with locking ball 6, dead bolt slide rail 24 is provided with the first low water 13 and the second low water 12 matched with locking ball 6, the front end of dead bolt 7 is provided with limited block 8, limited block 8 and dead bolt 7 are rotationally connected and this turning cylinder is located at the rear portion of limited block 8, limited block 8 side is provided with limited block top spring 18, and limited block top spring 18 is arranged between limited block 8 and dead bolt 7, and limited block top spring 18 withstands on the front portion of limited block 8, dead bolt 7 rear end is connected with dead bolt top spring 20, lock body 14 is also provided with the collision bead 11 matched with keeper 21, collision bead 11 is connected with the spacing disengaging push rod 9 matched with limited block 8, lock body 14 is provided with the spacing catch 10 matched with limited block 8, spacing catch 10 one end is fixed on lock body 14, the other end stretches out and is in before dead bolt 7, when the limited disengaging push rod 9 of limited block 8 promotes, limited block 8 front end can depart from spacing catch 10, when spacing disengaging push rod 9 departs from limited block 8, because the limited block top spring 18 of limited block 8 front portion acts on, promote limited block 8 to rotate, now limited block 8 front end is in the dead astern of spacing catch 10, and the limited catch 10 of limited block 8 blocks, be provided with the dead bolt return spring 23 matched with dead bolt 7 in lockhole 22, the elastic force of dead bolt return spring 23 is greater than the elastic force of dead bolt top spring 20.Locking bar 1 rear portion is provided with locking bar return spring 2, and locking bar return spring 2 one end is fixed on lock body 14, and the other end is fixed on locking bar 1.Dead bolt return spring 23 is concordant with the outward flange of lockhole 22, and dead bolt return spring 23 one end is fixed on lockhole 22, and the other end is concordant with the outward flange of lockhole 22.Spacing catch 10 is fixed on the front end of lock body 14 and does not exceed the outward flange of lock body 14.
When being in locking state, Cipher mechanism 4 engages with locking bar tooth bar 3, locking bar return spring 2 is in extended state, the locking bar dop 19 of locking bar 1 front end be in locking ball 6 below and hold out against locking ball 6, the locking ball 6 of below is now between the first low water 13 and the second low water 12, and the locking ball 6 of top contacts with locking bar dop 19, and dead bolt 7 stretches out lock body 14, dead bolt 7 front end to be in the lockhole 22 of keeper 21 and to contact with dead bolt return spring 23, and dead bolt return spring 23 is in compressive state.
When unblanking, being rotated by Cipher mechanism 4 drives locking bar tooth bar 3 to move forward, locking bar dop 19 promotes locking ball 6 and moves forward, and then drive dead bolt 7 to move forward, further compression dead bolt return spring 23, when locking ball 6 moves to the second low water 12, the locking ball 6 of below drops in the second low water 12, the locking ball 6 of top falls, locking bar dop 19 continues to move forward and crosses the locking ball 6 of top, now dead bolt return spring 23 acts on, promote dead bolt 7 to move backward, the locking ball 6 of below departs from the second low water 12 and moves backward with dead bolt 7, now locking ball 6 horizontal level of top raises and is stuck in locking bar limited impression 5, now Cipher mechanism 4 complete to code and and locking bar tooth bar 3 depart from, locking bar return spring 2 moves after shrinking and pulling locking bar 1, locking ball 6 due to top is stuck in locking bar limited impression 5, therefore dead bolt 7 moves backward with locking bar 1, when moving to the first low water 13 place, the locking ball 6 of below falls into the first low water 13, locking ball 6 and the locking bar 1 of top depart from, locking bar 1 moves reset after continuing, now dead bolt top spring 20 acts on dead bolt 7 driven forward, and when dead bolt 7 front end is concordant with lock body 14 front end, now collision bead 11 is depressed by keeper 21, spacing disengaging push rod 9 presses down and makes limited block 8 compress limited block top spring 18, and therefore limited block 8 front end can not stop by limited catch 10, end in contact before dead bolt return spring 23 and dead bolt 7 also stops dead bolt 7 to move forward, unblank to terminate, remove lock body 14 or keeper 21, now collision bead 11 is in ejection state, spacing disengaging push rod 9 departs from limited block 8, limited block top spring 18 promotes limited block 8 rotation and makes limited block 8 top withstand on spacing catch 10, and spacing catch 10 stops limited block 8 and dead bolt 7 to move forward, and prevents dead bolt 7 under unlocking condition from ejecting.
When locking, mobile lock body 14 or keeper 21 move, lock body 14 is alignd keeper 21, now keeper 21 depresses collision bead 11, spacing disengaging push rod 9 is made to depress limited block 8, limited block 8 front end and spacing catch 10 depart from, Cipher mechanism 4 resets and rotates, locking bar 1 is driven to move forward, locking bar dop 19 promotes locking ball 6 and dead bolt 7 moves forward, and overcomes the resistance of dead bolt return spring 23, makes dead bolt 7 front end extend in lockhole 22, when knowing that locking ball 6 is in the centre position of the first low water 13 and the second low water 12, complete and lock.
