Description
Technical field
The utility model relates to a kind of mechanical lock device, particularly relates to a kind of mechanical lock unlocking apparatus.
Background technology
Mechanical lock unlocking apparatus, uses clutch usually, and a kind of is roller, by roller carry-over moment, because the raceway on roller is special-shaped curved, manufacture, detect all more difficult, processing cost is high, and owing to being linear contact lay between raceway and roller, frictional force is little, easily occurs skidding after wearing and tearing, thus can not carry-over moment, clutch is caused to lose efficacy, poor reliability; In addition, roller one-way clutch, because of the reason of its structure, takes up room larger.Another kind of friction disk type one-way clutch, manufacturing process is complicated, and carry-over moment is limited, and inconvenience maintenance, seldom use.For micro motor use occasion as door lock, mahjong machine, curtain driving device, circuit breaker electric dynamic circuit connector brake mechanism etc., torque requirement is not high, work infrequently, but claimed structure is simple, volume is little, cost is low, above method volume is all comparatively large, cost is high, and above method is all inapplicable.
Therefore, create much for the improvement of clutch aspect, such as, application publication number is CN 103615160 A, the Chinese patent of application number 201310561457.5 discloses a kind of mechanical unlocking mechanism in emergency circumstances, and it includes a body, trigger mechanism assembly, repacking lock set; This structure can the unlocking mechanism design of Rapid reset, and be convenient to installation personnel and carry out Rapid reset and reuse, trigger mechanism assembly and repacking lock set adopt interlock design, and one-touch rapid triggering function is with can realizing prestissimo by door-lock opening.
But above structure is applied in unblanking in emergency circumstances, is not suitable for general house, office building etc., e.g., adopt triggering block structure, relate to more parts, be unfavorable for completing the work of unblanking simply, easily.
Therefore, this case adopts push rod, lock core orientation part and latch spring to coordinate latch fitting to complete and unblanks, and for above aspect, needs reasonably to improve prior art.
Utility model content
For above defect, the utility model provides a kind of to be convenient to unblank, structure is simple, cost is lower, be convenient to the mechanical lock unlocking apparatus safeguarded, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of mechanical lock unlocking apparatus, comprise main casing, latch, push rod, described main casing inside fixedly mounts motor box and installs latch at motor box top, this latch upper end is with latch spring I, described motor box inboard arranges push rod spacer and this push rod spacer arranged outside push rod, this push rod upper end connect with latch and the two joint with latch spring II, push rod lower end holds out against and is being arranged on the lock core orientation part above lock core.
Correspondingly, when lock core orientation part rotates forward 45 °, promote push rod by low spot to high point and boost 4 millimeters, drive latch to boost 4 millimeters;
When described lock core orientation part rotates backward 45 °, put point on earth by height, latch spring I extrudes, and push rod is to lower swing 4 millimeters.
Described main casing external surface sets gradually panel decoration part with trim and handle decoration, main casing inside fixed installation plug housing and plug housing inside arranges square steel positioning head.
The beneficial effect of mechanical lock unlocking apparatus described in the utility model is: coordinate latch fitting by arranging push rod, lock core orientation part and latch spring, can complete and unblank, when lock core orientation part rotates forward 45 °, promote push rod by low spot to high point and boost 4 millimeters, drive latch to boost 4 millimeters; When described lock core orientation part rotates backward 45 °, put point on earth by height, latch spring I extrudes, and push rod is to lower swing 4 millimeters.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
