The purpose of this utility model realizes with following technical scheme:
A kind of novel safety lock, it has lock body, sheet spring, locating rack, handle, spring, dead bolt and tongue connecting plate, locating rack is loaded in the lock body, handle is loaded on the locating rack through hole by lock body, dead bolt is loaded on tongue connecting plate front end, spring is loaded on the tongue connecting plate behind the dead bolt, it is characterized in that, on fixed chivalrous the through hole in lock body special-shaped cam is housed also
Be distributed with a of sheet spring control action on its special-shaped cam, b, three insurances of c anchor point, and d, two safety lock backing pins of e, a wherein, the b point is corresponding is located at position on the horizontal central line of special-shaped cam through hole, its c point is located between a, on the transition cancave cambered surface that orthodrome and roundlet arc have a common boundary between b, be provided with the locking backing pin e that contacts with tongue connecting plate baffle plate in special-shaped cam b point one side lower end, the tongue connecting plate concave surface that special-shaped cam center line marginal position in the same side the is provided with protrusion locking backing pin d that contacts, first insurance action dead bolt shrinks in the lock body, second insurance action dead bolt frees in and out on lock body, the outdoor indoor insurance that can't open was respectively by a on the special-shaped cam after the 3rd insurance action dead bolt stretched out lock body, b, the c point contacts with the sheet spring and finishes, and locking of first insurance action is backing pin e and the anti-mutually locking of tongue connecting plate baffle plate by special-shaped cam, and the locking that the 3rd insurance moved is that the backing pin d by special-shaped cam contacts lock in place with tongue connecting plate concave surface.
At the direct opening perk of above-mentioned locating rack one side T template pin installation sheet spring.
Be provided with guide strip in above-mentioned dead bolt one side.
The superiority that the utility model embodies is: special-shaped cam design is safe and reliable, makes its three insurances action accurately, and flexibly stable, structure design is simple, and cost of manufacture is low, and is easy for installation.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Accompanying drawing 1 structural representation of the present utility model.
Accompanying drawing 2 A-A sectional views of the present utility model.
Accompanying drawing 3 special-shaped cam schematic diagrames of the present utility model.
The upward view of accompanying drawing 4 special-shaped cams of the present utility model.
Among the figure: 1 lock body, 2 special-shaped cams, 3 springs, 4 locating racks, 5 tongue connecting plates, 6 dead bolts, 7 springs, 8 handles, 9 guide strips, 10 locking backing pin e, 11 locking backing pin d, 12 concave surfaces, 13 through holes, 14 tongue connecting plate baffle plates, 15T template pin.
As shown in the figure, locating rack 4 is housed in the lock body 1, tongue connecting plate 5 is housed on the locating rack 4, tongue connecting plate 5 front ends are equipped with dead bolt 6, on the tongue connecting plate 5 behind the dead bolt 6 spring 7 is housed, 2 on the special-shaped cam of making by above-mentioned shape is loaded on 5 of locating rack and tongue connecting plates, and 8 of handles pass lock body 1 and are connected installation sheet spring on the T template pin 15 of locating rack one side with tongue connecting plate 5 through holes with special-shaped cam 2 through holes 13
13, at its dead bolt 6 one sides the guide strip 9 that prevents dead bolt 6 plaies is housed.
Operating principle is: drive special-shaped cam 2 by handle 8 and rotate, abnormity cam 2 drives tongue connecting plate 5 and moves horizontally in lock body 1, dead bolt stretches under the effect of spring force and realizes three safety positions: (1) turns to a point by the special-shaped cam 2 of handle 8 drives and contacts with sheet spring 3, dead bolt 6 is shunk in the lock body 1, the active force of 3 pairs of special-shaped cams 2 of sheet spring this moment forms opposite moment with the power of e point and tongue connecting plate 5, cause special-shaped cam 2 to rotate, and keep tongue connecting plate 5 and special-shaped cam 2 positioning stablities reliable; (2) turning to the c point by the special-shaped cam 2 of handle 8 drives contacts with sheet spring 3, be on the transition cancave cambered surface of the orthodrome of special-shaped cam 2 and little circular arc this moment, make it be subjected to sheet spring 3 active forces very little, make dead bolt 6 enter the state of freeing in and out, because curve is reasonable in design, makes the turnover of dead bolt 6 more smooth and easy; (3) turn to the b point by the special-shaped cam 2 of handle 8 drives and contact with sheet spring 3, dead bolt 6 is stretched in outside the lock body this moment, simultaneously, because locking backing pin d
11With concave surface 12 lock in place on the tongue connecting plate 5, make dead bolt 6 opening outdoors, thereby realize indoor insurance function with key.
