The specific embodiment
Before describing embodiment in detail, it should be understood that and the invention is not restricted to the detailed structure below or described in accompanying drawing or arrangement of elements in the application.The present invention can be the embodiment that alternate manner is realized.And, should be appreciated that the wording and the term that use are only used as and describe purposes, should not be construed as limiting interpretation herein.The similar wording such as " comprising ", " the comprising " of using herein, " having " mean and comprise listed thereafter item, its equivalent and other additional things.Particularly, when describing " certain element ", the quantity that the present invention does not limit this element is one, also can comprise a plurality of.
As Fig. 1-4, key unlocking mechanism 10 is arranged in the panel 12 of lockset.So-called " panel ", in this article refers to lockset and is arranged on a surperficial part, in it, can include circuit or lockset operation interface, to realize, to being arranged on the lockset of a inside, partly operates.Thereby key unlocking mechanism 10 utilizes the rotation of key to drive tongue switching bar to stir dead bolt.In electric lock, key unlocking mechanism 10 is normally for emergent unlocking.
Key unlocking mechanism 10 comprises stirring the tongue switching bar 14 of dead bolt, the tapered end 18 that is built-in with lock core 16 and poke rod driven unit 20.Poke rod driven unit 20 is connected between lock core 16 and tongue switching bar 14 to utilize the rotation of lock core 16 and rotating lock tongue poke rod 14.
Poke rod driven unit 20 comprises actuator 22 and driving force transition components 24.Actuator 22 drives and is connected with tongue switching bar 14.Thereby driving force transition components 24 is connected between lock core 16 and actuator 22 and rotatablely moving of lock core 16 is converted to rectilinear motion driving tongue switching bar 14 rotations of actuator 22.In an illustrated embodiment, the straight-line direction of actuator 22 is vertical with tongue switching bar 14.Lock core 16 leaks outside in the side of described lockset.More specifically, in an illustrated embodiment, lock core 16 is positioned at the bottom side of panel of lock, is difficult for being found.
Driving force transition components 24 comprises worm screw 26, and lock core 16 drives and is connected when lock core 16 rotates, to drive worm screw 26 rotations with worm screw 26.In an illustrated embodiment, lock core 16 is placed side by side with worm screw 26, between with gear, connect.Particularly, on lock core 16, connect the first gear 28, on worm screw 26, connect the second gear 30, the first gears 28 and the second gear 30 engagements.In the embodiment not drawing at other, lock core 16 also can otherwise be connected with worm screw 26.For example, worm screw 26 is connected to lock core 16 the inners and is roughly located along the same line with lock core 16.On worm screw 26, there is tooth 32, between tooth 32, define teeth groove 34.
Actuator 22 comprises the actuation part 36 in order to activated drive part 22.Actuation part 36 is defined as to move along a straight line.Thereby actuation part 36 coordinates with the teeth groove 34 of worm screw 26 to promote actuation part 36 when worm screw 26 rotation, do rectilinear motion and cause actuator 22 to do rectilinear motion.In order to realize the rectilinear motion of actuation part 36, in an illustrated embodiment, thereby actuation part 36 can only be moved along the direction parallel with parallel bar 38 through limiting actuation part 36 by two parallel bars 38.Therefore, parallel bar 38 is parallel with worm screw 26, and is to be slidably connected with actuation part 36.Parallel bar 38 is arranged on a pedestal 39 that is positioned at worm screw 36 tops.
In an illustrated embodiment, actuator 22 comprises actuator body 40, and actuation part 36 is the separate parts that are fixed to actuator body 40, and it is block.Actuation part 36 is provided with projection 42, and projection 42 is matched with in the teeth groove 34 of worm screw 26.When worm screw 26 rotation, the tooth 32 of worm screw 26 promotes projection 42 motions, due to the restriction of parallel bar 38, cause projection 42 to move along a straight line, thereby actuation part 36 also can only rectilinear motion.Should be appreciated that described here is a kind of mode, and other realize the straight-line mode of actuation part 36 is also possible.
Actuator body 40 is longitudinal components, makes the tapered end 18 can be far away apart from tongue switching bar 14.In the present embodiment, actuator body 40 is fuel plate simple in structure and that be easy to manufacture.
In said structure, the rotation of worm screw 26 causes actuation part 36 to do rectilinear motion, thereby drives actuator 22 to do rectilinear motion.That is to say, worm screw 36 is by the rectilinear motion of conversion for actuator 22 that rotatablely move of lock core 16.
On tongue switching bar 14, be provided with swinging plate 44.Swinging plate 44 is set on tongue switching bar 14, fixing in direction of rotation with tongue switching bar 14.Actuator 22, thus specifically actuator body 40 is connected 44 rotations of utilization driving swinging plate and rotating lock tongue poke rod 14 with swinging plate 44.One of them is provided with projection actuator body 40 and swinging plate 44, and another is provided with link slot, and projection is engaged in link slot to realize both connections.In an illustrated embodiment, actuator body 40 is provided with link slot 46, and on swinging plate 42, correspondence is provided with projection 48.Be understandable that, actuator body 40 also can arrange other with swinging plate 44 and be connected structure to realize both driving connections.
Tongue switching bar 14 is arranged on mount pad 50.Swinging plate 44 is provided with guide protrusions (in Fig. 2, be positioned at swinging plate 44 belows and invisible), and mount pad is provided with guide rail 52, and the guide protrusions of swinging plate 44 and guide rail 52 coordinate to guide the rotation of swinging plate 44.On mount pad 50, be also provided with guide protrusions 54, actuator body 40 correspondences are provided with guide groove 56, and guide protrusions 54 is arranged in guide groove 56 with the motion of guiding actuator body 40.
Key unlocking mechanism 20 is also provided with flexible member 58.Flexible member 58 is as a reposition element, and after driving the external force of tongue switching bar 14 to disappear, reposition element 58 resets tongue switching bar 14.In an illustrated embodiment, flexible member 58 is connected with the guide protrusions of swinging plate 44, make the guide protrusions of working as swinging plate 44 towards away from its initial position (, when the direction settling position when being driven by external force) moves, the guide protrusions of 58 pairs of swinging plates 44 of flexible member applies one towards the biasing force of described initial position.
In above-mentioned introduction, the lock core of lock head of key actuated leaks outside in lockset side (for example, bottom surface), can make lockset front have clean and tidy beautiful outward appearance, and lockset position of coupler also should not be found by people.Tongue switching bar is far away apart from tapered end position, has increased the difficulty of technology unlocking.And in certain embodiments, the lock core of tapered end and driving force transition components are arranged side by side, thus make lock core also with actuator not point-blank, further increased the difficulty of technology unlocking.And the tongue switching bar actuator of introducing is herein plate and the block elements that is easy to manufacture, simple in structure, cost.
Concept described herein may be embodied to other form in the situation that not departing from its spirit and characteristic.Disclosed specific embodiment should be regarded as exemplary rather than restrictive.Therefore, scope of the present invention is by appended claim, rather than determines according to these descriptions before.At the letter of claim and any change in equivalency range, all should belong to the scope of these claims.
