CN2720029Y - Hand-driven separatable motor lock - Google Patents

Abstract

A hand-driven separatable motor lock comprises a motor, an endless screw, a worm-gear, a driving gear, an axle gearwheel, a handwork camshaft, a lock tongue and a lock case, and a motor endless screw, the worm-gear, the handwork camshaft and the lock tongue are connected in the lock case, The utility model is characterized in that the motor is connected with the endless screw, the endless screw is connected with the worm-gear, the worm-gear is provided with the driving gear, the upper end of the handwork camshaft is connected with a spring, the middle part is connected with the axle gearwheel, the bottom end is provided with a cam and a cam pin, and the axle gearwheel is anastomosed with the toothed racks on the driving gear and the lock tongue. The axle gearwheel can automatically lift and separate from the driving gear when rotating opening the lock with the handle, so users can open and close the door lock by handwork when the electricity is cut off or faulted.

Description

Manual separation formula electromechanical locks

Technical field

The utility model relates to a kind of manual separation formula electromechanical locks

Background technology

Electromechanical locks has simple in structure, mechanical wear is little, has overcome collision sound at closing time, has the effect of Long-distance Control start or stop, put on market and win warm praise from customers, the lockmaking industry also drops into great amount of manpower and material resources, develops the electromechanical locks of various functions, present electromechanical locks, its structure roughly is divided into the multi-stage gear speed change and pot is taken turns two kinds of pot lever changes, the former motor, gear, dead bolt are connected as a single entity, and the multi-stage gear speed change has speed unable during the dead bolt operation when electronic; Do not have speed when strong, in the time of manually (handle and key), former driving gear becomes driven gear, and driven gear becomes driving gear, and through multi-change speed, fragile former driving gear and breaking down loses the function of Active Unlocking; Accelerate the wearing and tearing of gear and motor simultaneously, lock body shortening in application life; The latter adopts the worm and gear structure, and dead bolt operation has speed, strong (dead bolt can be transferred to during the door body deformability) when electronic, but can't accomplish manually to unblank, locking, meet and have a power failure or lock body breaks down to meet an urgent need and opens the door, closes door.

Summary of the invention

The purpose of this utility model just provides a kind of manual separation formula electromechanical locks, adopt worm gear, worm structure, when with handle unlatching or locking lock, gear in the rotating shaft can separate with driven wheel, people accomplish manually to unblank, locking, and running into also can meet an urgent need when power failure or lock body break down opens the door, closes door.

The utility model is achieved like this, it comprises motor, worm screw, worm gear, driven wheel, shaft gear, manual camshaft, dead bolt, lock housing, in lock housing, be connected with motor, worm screw, worm gear, manual camshaft, dead bolt, motor connects worm screw, and worm screw connects worm gear, is connected with driven wheel on the worm gear, manually the camshaft upper end is connected with spring, the centre is connected with shaft gear, and the lower end is connected with cam and cam pin, and the tooth bar on shaft gear and driven wheel and the dead bolt matches.

The utility model rotarily opens when lock with handle, and shaft gear can rise automatically with driven wheel and separate, and makes people accomplish to have a power failure or when breaking down, also can be by manually opened or close door lock.

Description of drawings

Fig. 1 is a plane structure chart of the present utility model:

Fig. 2 is a generalized section of the present utility model:

In the drawings: 1, motor 2, worm screw 3, worm gear 4, driven wheel 5, manual camshaft 6, shaft gear 7, dead bolt tooth bar 8, lock housing 9, dead bolt 10, cam pin 11, cam 12, spring.

The specific embodiment

As Fig. 1, shown in Figure 2, the utility model comprises motor (1), worm screw (2), worm gear (3), driven wheel (4), shaft gear (6), manual camshaft (5), dead bolt (9), lock housing (8), in lock housing (8), be connected with motor (1), worm screw (2), worm gear (3), manual camshaft (5), dead bolt (9), motor connects worm screw, worm screw connects worm gear, be connected with driven wheel (4) on the worm gear, manually the camshaft upper end is connected with spring (12), the centre is connected with shaft gear (6), the lower end is connected with cam (11) and cam pin (10), dead bolt tooth bar (7) on shaft gear and driven wheel and the dead bolt (9) matches, and people are as long as rotate manual camshaft with handle, and then cam pin is up carried manual camshaft, drive on the shaft gear and move, thereby be separated with driven wheel, shaft gear promotes dead bolt and moves, and the driving dead bolt puts in and stretches out, when manual disappearance, shaft gear is under the effect of spring force, and nature meshes with driven wheel, and realization motor-driven dead bolt puts in and stretches out function.

Claims (1)

1, a kind of manual separation formula electromechanical locks, it comprises motor, worm screw, worm gear, driven wheel, shaft gear, manual camshaft, dead bolt, lock housing, in lock housing, be connected with motor worm, worm gear, manual camshaft, dead bolt, it is characterized in that motor connects worm screw, worm screw connects worm gear, is connected with driven wheel on the worm gear, manually the camshaft upper end is connected with spring, the centre is connected with shaft gear, and the lower end is connected with cam and cam pin, and the tooth bar on shaft gear and driven wheel and the dead bolt matches.
