Abstract

The utility model relates to an electrical control lock opener, which is mainly composed of a motor, a clutch-typed driving device and a connector connected with the neck of a handle of a door lock. The utility model is matched with the existing mechanical door lock. When the handle of the door lock is affected, the lock is unlocked. The utility model has the advantages of simple structure, easy installation, low cost, etc.

Description

Electrical control lock opener

The present invention is a kind of automatically controlled lockaid gun, is specially adapted to door lock.

The automatically controlled dual-purpose door lock of existing mechanical owing to complex structure, can not be inherited the technology of original mechanical door lock, can not keep the appearance style of mechanical door lock simultaneously, more can not be transformed into mechanical automatically controlled dual-purpose door lock to the mechanical door lock in usefulness.

The purpose of this invention is to provide a kind of automatically controlled lockaid gun that can be used with mechanical door lock, utilize automatically controlled lockaid gun that affecting of Door lock handle realized unblanking, mechanical door lock is cooperated with automatically controlled lockaid gun becomes the automatically controlled dual-purpose lock of a kind of new mechanical.

The present invention is achieved in that by electromagnetic driving system, by transmission mechanism, drives and has the disengaging type that machinery separates affect device under reset mode, and disengaging type affects device to affect to be bound up on the connector of Door lock handle suitable position.When unblanking, the electromagnetic driving system energising affects device and connector by transmission mechanism, disengaging type, affects Door lock handle to rotate an angle, makes the door latch spring bolt thread off or withdrawal, reaches and unblanks.After opening the door, electromagnetic driving system outage or oppositely energising, make disengaging type affect device and Door lock handle to reset, disengaging type affects device to be in mechanical released state under reset mode, makes that mechanical force can not be from Door lock handle this side reverse drive to transmission mechanism and to electromagnetic driving system (is the situation of turning round Door lock handle as the people).

The present invention is described in detail by the following examples in conjunction with the accompanying drawings.

Fig. 1 is the sectional view of automatically controlled lockaid gun under unlocking condition;

Fig. 2 is the sectional view of automatically controlled lockaid gun under reset mode;

Fig. 3 has the annular connector of opening and the connection lateral view of Door lock handle.

Referring to figs. 1 through Fig. 3, be bound up on the connector 1 and chain 2(or wire rope of Door lock handle 8 suitable positions) snapping, the other end of chain 2 and pull bar 3 snappings, the reset back-moving spring 4 of usefulness of pull bar is housed on the pull bar 3, on the output shaft 6 of transmission mechanism, be fixed with crank 5(or cam), crank 5 when unblanking in order to stir pull bar 3, limited stopping after angle of crank 5 counter-rotating when resetting, its stop position is with the rectilinear motion that breaks away from pull bar 3 and do not hinder pull bar 3 be as the criterion (this process can be described as tangential clutch).Wherein, chain 2, pull bar 3, back-moving spring 4 and crank 5 composition disengaging types affect device.The structure of connector reaches and the bind mode of Door lock handle has several down: one, connector is an a kind of circle or multi-circle spiral flow shape connector, the spirality connector rolls with elastic wire, its internal diameter is more smaller than Door lock handle recess diameter, and the spirality connector relies on its radical elasticity tightly to be enclosed within the Door lock handle neck.They are two years old, connector is a kind of annular connector with opening, be useful on the screw of regulating opening on the opening, the neck that this annular connector is enclosed within Door lock handle 8 as shown in Figure 3, they are three years old, connector is a kind of annular connector with opening, and makes with elastomeric material, tightly is enclosed within the neck of Door lock handle 8 by its elastic force; Its four, for improve connecting reliability, can be split into profile of tooth at the inner periphery of annular connector with opening; Its five, connector can be bonded on the suitable position of Door lock handle with cementing agent; Its five, strong permanent magnet is housed on the connector, tightly inhale on the suitable position of Door lock handle.In addition, disengaging type affects the also available gear drive of machine driving between device and the connector.Disengaging type affects device " clutch " structure except that adopting described radially disengaging type, can also adopt complicated a little axial disengaging type structure.Dash number 7 is automatically controlled lockaid gun shells in the accompanying drawing.

The course of action of unblanking and resetting of automatically controlled lockaid gun is, when unblanking, the electromagnetic driving system energising, output shaft 6 drive cranks 5 by transmission mechanism clockwise rotate, stir pull bar 3, affect connector 1 and Door lock handle 8 to rotate an angle, the door latch spring bolt is threaded off or withdrawal by chain 2, realization is unblanked, as shown in Figure 1.After opening the door, electromagnetic driving system outage or oppositely energising, make output shaft 6 counter-rotatings, driving crank 5 is inverted on the position that breaks away from pull bar 3 limited (electromagnetic driving system outage after this), crank 5 does not hinder pull bar 3 moving linearlies on this position, be crank and pull bar be in " from " the position, automatically controlled like this lockaid gun is in reset mode, as shown in Figure 2.Simultaneously Door lock handle resets by self elastic force revolution, and the door latch spring bolt stretches out.If artificially Door lock handle 8 inhours are reversed the situation of room inward (for example), pull bar 3 is just spurred left and is not stretchy crank 5 of pull bar 3 away from crank 5(), back-moving spring 4 is compressed simultaneously, after Door lock handle automatically reset by self elastic force, 3 on pull bar was resetted by back-moving spring 4.

The electromagnetic driving system of the automatically controlled lockaid gun of the present invention can be a motor, also electromagnet, and transmission mechanism can adopt linkage or gear train or worm-and-wheel gear.

Automatically controlled lockaid gun is installed in one of an inboard door locking handle and is close to, connector is bound up on the appropriate location of Door lock handle, mechanical door lock just becomes a kind of simple in structurely like this, install to be easy to mechanical automatically controlled dual-purpose door lock, if mix the electronic cipher circuit, be exactly a kind of electronic cipher door lock.

Claims

1, a kind of automatically controlled lockaid gun, be specially adapted to door lock, form by electromagnetic driving system, transmission mechanism and unlocking apparatus, it is characterized in that unlocking apparatus comprises and be used to connect the connector of Door lock handle and be used to affect having the disengaging type that machinery separates under the attitude at the dress that resets and affecting device of connector.
