Description

From establishing Puzzle electronic lock

(1) technical field: the utility model relates to the building door locks, is that a kind of being loaded on established Puzzle electronic lock on the door certainly.

(3) background technology: lockset is the main accessory on the door, and door lock is mainly used cylinder lock at present, and its key is lost easily, make troubles to people, the someone has designed mechanical code lock, and its structure is comparatively complicated, the accuracy of manufacture requires high, and the cost height is prone to fault.

(3) summary of the invention: the utility model will address the above problem exactly, propose a kind of simple in structure, cost is low, reliable operation establish Puzzle electronic lock certainly.

Concrete scheme of the present utility model is: it has lock box, battery case, be contained in the dead bolt in the lock box, drive the electric device of dead bolt, and the password key device of control electric device, it is characterized in that: each button on a. password key device is to constitute like this: the button that is exposed at password key crust of the device upper surface, back-moving spring and thimble are equipped with in the button below, a pair of static contact A that is in contact with one another and elasticity movable contact spring are equipped with in the below of thimble, thimble is equipped with static contact B more successively over against the elasticity movable contact spring below the elasticity movable contact spring, electromagnetic core, permanent magnet; B. each button is connected with power supply, electric device, wherein: the elasticity movable contact spring on each button is directly to seal in circuit, static contact A and static contact B seal in circuit again after the parallel connection, and the static contact B on the button of non-password position is disconnected sealing in circuit front-end, and the static contact A on the button of password position is disconnected sealing in circuit front-end; C. installed around coil on each button electromagnetic core outer wall, connected with power supply and a reset switch behind each coils from parallel connection of coils.

Can not unblank for preventing that button from breaking down, the utility model is installed on a special switch specially and connects with power supply, electric device, special switch is to be contained on the backing face of lock box, and directly unblanking when button breaks down, owner unblanks in can buying a house in installments simultaneously.

The utility model is simple in structure, cost is low, and reliable operation is easy to operate, and the secrecy height can be established password certainly according to user's needs.

(4) description of drawings:

Fig. 1 is the utility model lock box part-structure schematic diagram;

Fig. 2 is the utility model password key device schematic perspective view;

Fig. 3 is A-A sectional view and the circuit connection diagram of Fig. 2;

Fig. 4 is a key circuit operating principle sketch.

Among the figure, 1-lock box, 2-dead bolt, 3-battery case, the 4-motor, 5-reducer, 6-driving wheel, 7-password key crust of the device, 8-button, 9-back-moving spring, the 10-thimble, 11-static contact A, 12-elasticity is advised contact, 13-static contact B, 14-electromagnetic core, 15-coil, the 16-permanent magnet, 17-reset switch, the special switch of 18-.

(5) specific embodiment: the utility model mainly is made up of lock box (assembly) part and password key device and contactor.The lock box part is referring to Fig. 1, and it has lock box 1, is contained in the dead bolt 2 in the lock box, the electric device (including motor 4, reducer 5, driving wheel 6) of driving dead bolt, and battery case 3 is made one with lock box 1.

Its profile of password key device is referring to Fig. 2, it has shell 7, in 19 buttons (letter shift among the figure) and reset switch (" 0 " position among the figure) are housed, the structure of each button is referring to Fig. 3, it has a plastic button 8, and upper surface indicates letter so that recognize, remember.Back-moving spring 9 and thimble 10 are equipped with in the below of button, irony elasticity movable contact spring 12 and static contact A11 are equipped with in the below of thimble 10, two contacts form " door " font relatively, are in contact with one another under the normality, and static contact B13, electromagnetic core 14, permanent magnet 16 are housed in " door " successively.

Button of the present utility model is and power supply, motor 4 series wirings, its physical circuit connects referring to Fig. 2, elasticity movable contact spring 12 on each button is directly to seal in circuit, static contact A11 and static contact B seal in circuit again after the parallel connection, the user cuts off the static contact B on the button of non-password position sealing in circuit front-end according to the password of establishing certainly, (as A, D button position among Fig. 2), and the static contact A on the button of password position is cut off (B, C button position in as Fig. 2) sealing in circuit front-end.

On the utility model electromagnetic core 14, be wound with coil 15, connect with reset switch 17 and power supply again after each coil 15 parallel connection, form independent loop.

For preventing that button from breaking down, be convenient to that owner unblanks in the room, a special switch 18 is housed on the backing face of lock box connects with power supply, motor 4, form independent loop.

Button operating principle of the present utility model is summarized as follows: referring to Fig. 4, in fact, non-password of the present utility model position button is a normal open switch, and the password position is a normally closed switch.Circuit will be disconnected when pressing non-password position button, circuit will be connected and press password position button.Its mechanical action is: press the button 8, thimble 10 breaks away from static contact A11 and connects with static contact B13 thereupon downwards elasticity movable contact spring 12 being depressed, and can arbitrarily not break away from after connected with static contact B13 by the effect elasticity movable contact spring 12 of permanent magnet 16.The attitude that restores to the original state must be pressed reset switch 17, is about to coil 15 energisings, thus produce one with permanent magnet 16 rightabout magnetic fields, elasticity movable contact spring 12 is got loose resets.
