As shown in fig. 6, the lock base 3 is provided with three annular grooves surrounding the center, the innermost rings of the three annular grooves are respectively an unlocking rotating groove 31, an emergency rotating groove 32 and a steel ball rotating groove 33 from inside to outside, the unlocking rotating groove 31 and the emergency rotating groove 32 are used for being matched with a blocking shaft 61 of the electromagnet 6, and the steel ball rotating groove 33 is used as a sliding groove of the steel ball 13; a blocking shaft through groove 34 is arranged between the unlocking rotating groove 31 and the emergency rotating groove 32 along the radial direction, and a blocking shaft 61 on the electromagnet 6 can be sucked and extend out in the vertical position of the blocking shaft through groove 34 in the closed state. The steel ball rotating groove 33 on the lock seat 3 is provided with four limiting grooves 35 for limiting the steel balls 13, the tailstock 9 is provided with two through holes for placing the steel balls 13, the steel ball springs 14 and the steel balls 13 are sequentially placed into the through holes 91 of the tailstock 9, and the support 17 is fixed on the top surface of the tailstock 9, so that the steel balls 13 are limited on the limiting grooves 35 of the lock seat 3 under the action of the steel ball springs 14. It should be noted that the unlocking rotation groove 31 may be a groove.
The shell 1 is internally provided with a plurality of counter bores (shown in figure 8) for installing the bolt springs 20 and the bolts 19, and the bolt springs 20 and the bolts 19 are sequentially sleeved in the counter bores of the shell 1 and are fixed and limited by the lock shell cover 4 fixed on the shell 1; the lock shell 2 is provided with a plurality of through holes 22 (shown in fig. 7) for installing the step marble 18, and the lock shell 1 is fixedly provided with a retainer ring 10 for fixing and limiting the step marble 18; the step marble 18 and the plug 19 have different sizes, and the specifications of the step marble 18 and the plug 19 which are arranged clockwise are 'small', 'medium', 'large'.
The working principle of the invention is as follows:
1. the lockset idles: when the rotating sleeve 5 rotates, the stop block 7 moves forwards and backwards under the action of the wavy ring 51 and the springs (as shown in fig. 2 and 3), and at the moment, the force provided by the two steel ball springs 14 and the steel balls 13 is far greater than the force provided by the two steel ball springs 14 and the stop block 7, so that the tailstock 9 cannot be driven to rotate by the rotating sleeve 5. The rotating sleeve 5 is connected with the lock shell 2, the lock shell cover 4 and the shell 1, so that the rotating sleeve 5 is driven to rotate when the shell 1 is rotated, and the lock cannot be opened, thereby realizing the idling effect.
2. Unlocking the lockset: the electronic lock uses an IC card, and a plurality of cards with multiple stages can be recorded for customers to use.
Referring to fig. 6, the unlocking rotation groove 31 on the lock base 3 is a rotation groove moving in the state that the movable iron core of the electromagnet 6 is sucked, and the wall between the unlocking rotation groove 31 and the emergency rotation groove 32 can prevent the baffle shaft 61 from being ejected when rotating, so that the unlocking is disabled. The middle emergency rotation groove 32 is a groove for the movement of the blocking shaft 61 during emergency unlocking, and the largest steel ball rotation groove 33 is a groove for the movement of the steel ball 13.
As shown in fig. 1, 2, 4 and 5, when the IC card is used to punch a card in an energized state, a green light on the circuit board blinks, and a movable iron core on the electromagnet 6 is retracted. When the blocking shaft 61 is retracted, the blocking shaft 61 is positioned between the two blocking blocks 7 on the tailstock 9, the shell 1 is rotated at the moment to drive the rotating sleeve 5, and the wavy ring 51 on the rotating sleeve 5 presses the blocking blocks 7, but the blocking blocks 7 cannot move forwards and backwards due to the blocking of the blocking shaft 61 between the two blocking blocks 7. In this case, the housing 1, the lock housing cover 4, the lock housing 2, the sleeve 5, the stopper 7, the stopper shaft 61, the tailstock 9, the lock cylinder tailpiece 11, and the tongue piece 12 are considered to be integrated. When the force provided by the shell 1 which rotates clockwise is larger than the force of the two steel balls 13 and the steel ball spring 14 on the tailstock 9, the tongue piece 12 can be driven to achieve the unlocking effect.
When the lock is turned 90 degrees clockwise to unlock, the blocking shaft 61 on the electromagnet 6 is still positioned in the smallest groove on the lock seat 3, and at the moment, the electromagnet 6 is still in a retracted state even if not electrified, so that the two stop blocks 7 can be clamped. At this time, if the shell 1 is rotated anticlockwise, the tongue piece 12 can be driven to rotate, so that the locking effect is achieved.
3. Emergency unlocking: six counter bores are arranged in the shell 1 and are used for installing a bolt spring 20 and a bolt 19, and the lock shell cover 4 is locked on the shell 1 by bolts to play a role in fixing and limiting the bolt 19. The lock shell 2 is provided with 6 through holes for installing the step marble 18, and the retainer ring 10 is locked under the lock shell 2 by a machine tooth screw and is used for fixing and limiting the step marble 18. The step marble 18 and the plug 19 have three dimensions, and the dimensions of the step marble 18 and the plug 19 which are arranged clockwise are 'small', 'medium', 'large'. This arrangement is to prevent the step pins 18 and pins 19 from getting stuck in the grooves of the lock housing 2 when they are rotated. When the shell 1 and the lock shell 2 are installed, the shell 1 is clockwise installed in the lock shell 2, and 6 bolts 19 on the shell 1 are turned into 6 through holes on the lock shell 2, so that the shell 1 and the lock shell 2 are fixed.
When the emergency key is used, the tooth on the key pushes the step marble 18 onto the plane where the lock shell 2 is contacted with the lock shell cover 4, and the step marble 18, the bolt 19, the lock shell 2 and the lock shell cover 4 are on the same plane. Turning the housing 1 counter-clockwise removes the housing 1 from the lock housing 2 (as shown in figure 12).
The battery cover, the battery seat 16, the support 17, the tailstock 9, the lock cylinder tail 11 and the tongue piece 12 are connected together. When the battery holder 16 is rotated clockwise in a state where the housing 1 is removed, the stopper 61 of the movable core of the electromagnet 6 moves in the stopper through-groove 34 in the upper portion of the lock holder 3. When the force of the battery seat 16 rotating clockwise is larger than the force of the steel ball spring 14 and the steel ball 13 on the tailstock 9, the battery seat 16 drives the tongue piece 12 to rotate clockwise, and an emergency unlocking effect is achieved. Similarly, rotating the battery holder 16 counterclockwise in this state may lock the lock.
4. And the battery is quickly replaced: in the state where the housing 1 is removed, the battery-mounted mount 15 may be taken out from between the battery cover 21 and the battery holder 16, replaced with a new battery, and the mount 15 may be reinserted into the battery holder 16 and the battery cover 21 to achieve a function of easily mounting the battery (as shown in fig. 13).
The foregoing description is only illustrative of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, i.e., the equivalent changes and modifications to the invention as described in the claims and specification should be considered as falling within the scope of the invention.
