Description

Door handle type digital door lock that can be self-generated and easy to detach

The present invention relates to a digital door lock and to a self-generating and easy detachable, but also to a self-powered and easy removable door handle type digital door lock using a simple gear structure.

In general, door locks are installed on the doors to arbitrarily control the entrance and exit of a work room provided in a home (room, bathroom) or an office. As described above, the door lock installed on the door rotates any one of the inlevers or the out levers to unlock the latch bolt constituting the lock case of the door lock from the strike installed on the door frame. In general, the lever-type door lock has a lock formed under the latch and lever used to open and close the door, and the lock is divided into two types to lock and unlock the door only from the inside, and to lock and unlock the door from the inside. It can be divided into the types of locking and unlocking. In the latter case, a latch and a lever for opening and closing the door are formed under the lock to perform each function separately from each other.In the case of the former for locking and releasing the door only from the inside, the door is opened and closed. The parts of the latch and the lever are engaged with each other.

However, the lever-type door lock, which locks and releases only in the conventional inner side, is locked through the stop groove of the lever. If the inner lever is rotated without releasing the lock state in the locked state, the lever is not rotated, and a load is applied to the lever and the locking function to damage it. The overall function of the door lock has been lost, and productivity is reduced by integrally forming the lever and the shaft housing, and the entire door lock is replaced to change the design of the door lock.

In order to solve the above problems, the 'lever door lock' has been disclosed in Korean Patent Application No. 20-1999-0038232 published by the Korean Patent Office. As shown in FIG. 29, the conventional 'lever door lock' includes a lever 10, a shaft housing 20 coupled to the insertion groove 11 of the lever 10, and a shaft housing 20. Restoration unit 30 for coupling the inner cover 35, the spring 36 and the spring cover 37 with an elastic hook 38, the shaft housing 20 and the lever 10 of the restoration unit 30 Both ends are coupled and the shaft 40 is rotatably formed at the center, and the central portion of the shaft 40 is inserted into the inner and outer cams 51a and 51b and moved by the rotation of the cams 51a and 51b. The moving piece 57, the latch part 50 having the latch 59 arranged on the moving shaft 58 provided on the moving piece 57, and the latch part 50 wrapped up and down, The latch housing 60 forming the 69, and the fixture 70 for fixing the latch housing 60 and the fixing rod 39 to both sides.

Located between the clutch recesses 1655, a second clutch 1657 protruding radially outwardly is provided on an outer surface of the clutch extension part 1653 on the outer surface of the clutch extension part 1653. The clutch second protrusion 1657 is inserted into the clutch second protrusion inserting portion 1619 of the outer center portion 1600.

Therefore, the clutch 1650 is combined with the outer center portion 1600 by the inner concentric protrusion insertion hole 1663, the clutch recess 1655, and the clutch second protrusion 1657, thereby being integral with the outer center portion 1600. Is rotated.

As shown in FIG. 14, the gear body 1700 is provided in the outer case 1100 in the space portion. A gear body case 1702 coupled to the outer case 1100 to the side of the outer center shaft 1600, and a driven gear part provided in the gear body case 1702 and engaged with the driving gear; And a generator connected to the driven gear part.

A gear body coupling hole 1703 into which the outer case coupling part 1117 of the outer case 1100 is inserted is formed in the gear body case 1702. The outer case coupling part 1117 is inserted into the gear body coupling hole 1703 and is screwed to fix the gear body 1700 to the outer case 1100.

The driven gear part is composed of a plurality of gears, and a plurality of rotation shaft holes 1705 are provided in the gear body case 1702 provided with gear shafts of the driven gear part.

The gear body inner surface portion 1701a of the gear body case 1702 facing the center axis of the driven gear portion is opened toward the center of the outer case 1100 such that the driven gear portion engages with the drive gear. The gear body inner surface portion 1701a is formed at both ends with a gear body protrusion 1707 protruding toward an end portion of the gear body inner surface 1701a.

The outer diameter of the clutch side protrusion 1659 is larger than the inner diameter of the gear body protrusion 1707. Therefore, when the clutch 1650 is rotated by the rotation of the outer handle 1200, the clutch side protrusion 1659 rotates and is caught by the gear body protrusion 1707. When the clutch side protrusion 1659 is caught by the gear body protrusion 1707, the clutch 1650 may not be rotated. Therefore, the outer handle 1200 is rotatable only at a certain angle.

As shown in FIG. 22, when the outer knob 1200 is rotated, the drive gear provided in the outer central shaft 1600 is integrally rotated. The driven gear is rotated by the rotation of the drive gear to generate kinetic energy, and the generated kinetic energy is converted into electrical energy through the generator. The converted electrical energy is stored in the capacitor.

The storage battery is provided in the outer case 1100 in the space part and is connected to the generator and charged. The storage battery is connected to the control unit and the latch unit 1800 to transmit power.
