Description

A kind of lock electrical converter

Technical field

The utility model relates to the lockset field of mechanical technique, is meant a kind of lock electrical converter especially.

Background technology

The common mechanical lock body has oblique dead bolt (or windproof dead bolt), main dead bolt, locks three part dead bolts of dead bolt, and tiltedly dead bolt (or windproof dead bolt) safety is relatively poor relatively.People when going out, often adopt the safeguard protection thinking of mechanical key back locking, for security needs under general situation now; only lock oblique dead bolt (or windproof dead bolt),, must use mechanical key back locking if will lock main dead bolt; like this, the trouble that operates, sometimes even forget and lock.The resident wishes, can not change original lock body, lock housing before and after only changing, just can become electric lockset to original mechanical lock, and under existing technology status, can only change the whole of mechanical lock again, and because of the electronic lock lockhole that newly changes and the frequent disunity of lockhole of mechanical lock, be from new perforate, cost is higher, and certain degree of difficulty is also arranged in the operation.

Simultaneously in general electric lockset, the arrangement of clutch and the transmission process of general lockset are, gear under the driven by motor rotates, the gear driven worm screw is rotated or the driven by motor worm screw is directly rotated, promote the elastic wire be connected with it again, transmission is sliding friction on the one hand in the process that electromechanics transforms, transformation efficiency is low, the long-term use of elastic wire can be that steel wire itself follows the string simultaneously, thereby make the transmission pin of lockset can not normally control the clutch process of lockset, thereby electric lockset can not be run well.

The utility model content

In view of this, the utility model is to provide a kind of lock electrical converter, to solve problem, the repacking problem of mechanical lock and the problem that the transmission efficiency in the electric lockset lowly reaches fluctuation of service that exists in the use of above-mentioned electronic lock and mechanical lock.Be dead handle every belonging to outdoors, and the mechanical lock body that can directly open the door in the door can both be directly changed into electric lock.The motor translation exception of all electric locks all can be readily solved.

For addressing the above problem, the utility model provides a kind of lock electrical converter, comprises containing angle of rake electromechanical transformation apparatus, connecting lock body open the door movable axle sleeve, transmission pin, track sheet, gear shifting device, the movable pin of turning cylinder.

Describedly contain angle of rake electromechanical transformation apparatus and can apply back and forth the power that advances to the track sheet by propeller.

Movable pin is installed in the gear shifting device, and can be free movable;

The track sheet applies back and forth propulsive force by the track sheet to movable pin;

Movable pin and transmission pin are point-blank installed, and moving back and forth of movable pin drives the stretching motion that the transmission pin is opposed and answered.

Described electromechanical transformation apparatus comprises:

Driven wheel, with the driven primary and secondary gear of driven wheel engagement, with the gear wheel of sub-gears engaged in the driven primary and secondary gear, the worm screw that is connected with gear wheel, the rolling sheet that is connected with worm screw;

Female tooth engagement of described driven wheel and driven female gear, gear wheel is installed on the worm screw, and worm screw is rotated synchronously along with the rotation of gear wheel, and the rotation of worm screw drives and the rolling sheet of its engagement rotates, and the suitable reverse turn of rolling sheet promotes propeller and makes back and forth movement.

Between worm screw in the described dynamo-electric converter device and rolling sheet is rolling friction.

The pitch of described worm screw is 1.2mm.

In the hole of described movable axle sleeve, also have when propeller moves downward, promote the spring of transmission pin playback.

The diameter of described driven wheel is taken turns less than the mother in the driven primary and secondary gear; The diameter of the son wheel in the driven primary and secondary gear is less than the diameter of driven gear.

Described track sheet is a semicircular arc, an end axial location wherein, and the other end contacts with propeller by the horizontal retaining on the circular arc.

Lock electrical converter in the utility model, because of directly putting into lock housing, can be connected with the turning cylinder that opens the door of standard machinery lock body handle, under the situation that does not change installing hole on original door, directly install, installation cost is lower, realizes simultaneously the standard machinery lockset directly is converted to electric lockset.

Lock in the utility model is with in the electrical converter, adopt the transmission process of 3 gears, because of being connected the diameter of gear greater than the travelling gear that is connected with motor with worm screw, the power of transmission is exaggerated, thereby can use more low power micro-machine, lower the energy input of electronic lock, electronic lock is done becomes possibility for a short time.

The process of the transmission in the utility model has adopted the form of worm screw and rolling sheet to carry out, guarantee on manufacture craft that simultaneously its relative motion is to be undertaken by rolling friction, can overcome the wear problem between mechanical part in original mechanical transmission course on the one hand, because of less frictional force, also significantly improved the conversion efficiency in the dynamo-electric transfer process simultaneously.

Electrical converter part in the utility model can be directly installed in the ordinary electronic lockset simultaneously, replace the clutch running part in original lockset, advance the mode of rolling sheet because of the worm screw of arrangement of clutch employing of the present utility model, so the elongated situation that influences result of use in the process of clutch, can not occur because of service time, can reduce frictional force because of angle of rake long-term friction on the contrary, make use more efficient.

Simultaneously the utility model has also embodied the thought of split design, can better change existing lockset, better maintaining lockset in the lockset use.
