Abstract

The utility model discloses a lock device. A transmission plate lifted by a button is arranged inside an outer lock of the lock device, a meshing wheel is meshed onto the inner side of the transmission plate, the meshing wheel is combined with a rotating rod which drives latch bolts of an European-style multi-point lock to retract inwards, a switch button and a handle are arranged on the top and at the bottom of an inner lock, the handle can rotate a linkage component via a handle driving shaft combined with a handle reset spring, and rotation of the linkage component drives the inner ends of the rotating rods and the inner end of the switch button. Both the pressing button and the handle can unlock a latch to open a door, the lock device can avoid excessively large force for door opening since the downwardly pressed press button for unlocking the latch cannot be linked with the handle reset spring of the inner lock in motion, and simultaneously the design adopting once unlocking allows a user to rapidly open the door for life saving in emergency because when the handle is pressed, the latch bolt and a dead bolt can be simultaneously driven to inwards contract.

The position in joint correcting hole 452 in the correspondence, wear the middle joint locating hole 462 of a circle in the centre of bed plate 46, be sheathed on middle joint locating shaft 442 with middle joint locating hole 462, the position in joint correcting hole 453 on the correspondence, wear going up of a circle in the top of bed plate 46 and save locating hole 463, place a release knob seat 48 in last joint locating hole 463 and last joint correcting hole 453 with rotating form, be nested in the inner of tapered end driver plate 21 and the front end of the bar 431 of rising as high as the banks respectively with its front end and rear end, can rotate in the same way with release knob seat 48 interlock tapered end driver plates 21 when making release knob 43 reverse by this;

Bed plate 46 is resisted against the inner of saving joint holding nut 22 on the back nut 133 and two for twice, joint holding nut 22 wears four in bed plate 46 screw hole 464 is installed on corresponding twice joint back nuts 133 and two, correspondence is respectively installed screw hole 464 and is provided with one screw 49 is installed, each install screw 49 pass screw hole 464, each time joint back nut 133 respectively are installed or save each on holding nut 22 also screw lock in the positioned internal of handle base 11.

As Fig. 2 and shown in Figure 6, when the utility model is installed, be that European multiple spot locker 30 is loaded on the interior left side of door, make each oblique tongue 31 stretch out by a Men Bianchao left side, again outside lock body 10 and inboard lock body 40 are installed on the outside of door and the inboard of door respectively, when dwang 16 rotates, can drive in the mode of rotating this commentaries on classics hole 32 in each oblique tongue 31 of European multiple spot locker 30 and contract, reach and separate the effect that door bolt opens the door, key can be inserted tapered end 20 by the outside of door rotates, can clockwise rotate transmission plate hole 34 and the side's of drive tongue 33 with tapered end driver plate 21 this moment and stretch out, reach the effect of locking a door towards a left side.

When the utility model presses the button 12 or when pressing down handle 421, can both make dwang 16 rotate, in addition, the operation that presses down handle 421 can also be by the interlock of interlock plate assembly 44, make tapered end driver plate 21 be rotated counterclockwise simultaneously and contract in the side's of allowing tongue 33, even reach square tongue 33 with on the door lock, depress handle 421 still can separate the door bolt open the door.

When pressing the button 12 of outside lock body 10, as Fig. 7, shown in Figure 8, the drive surface 122 of button 12 the inners can promote driver blade 141 up, the meshing wheel 15 that this moment, driver plate 14 can drive engagement with tooth bar 142 with and the dwang 16 of sheathed combination rotate towards clockwise direction, driving with dwang 16 changes holes 32 and makes oblique tongue 31 retractions and separate door bolt and open the door, when aforementioned operation is finished and is decontroled button 12, back-moving spring 144 can promote driver plate 14 and move down, and interlock tooth bar 142 and button 12 are got back to initial position.

Aforementioned button 12 is separated and is fastened with a bolt or latch in the process of opening the door, because the interlock swash plate 163 during dwang 16 is inserted in joint locating shaft 442 front ends can dally in middle joint locating shaft 442 in the mode that turns clockwise, can not fasten each buckle shape 4421 in the process, therefore as shown in Figure 4, can not drive interlock plate assembly 44 and rotate handle driving shaft 471, drive handle return spring 47 motion simultaneously in the time of can avoiding outside button 12 to separate door bolt, the excessive problem of the strength of opening the door that causes by handle return spring 47 when avoiding button 12 to press.

Be to rotate 90 degree when rotating switch button 43 with clockwise direction, as Fig. 9, shown in Figure 10, its interlock plate assembly 44 and release knob seat 48 that can drive the front end combination together rotates, drive tapered end driver plate 21 simultaneously towards clockwise direction rotation with release knob seat 48, rotate the transmission plate hole 34 of European multiple spot locker 30 by this, square tongue 33 drivings are stretched out towards a left side, reach the effect of locking a door; And interlock plate assembly 44 also rotates towards clockwise direction in the process of locking a door, can top sheave 445 be spurred up together with track plate 446 with C shape ditch 4442 anticlockwise ends during rotation, make the top of trace 448 on two be displaced downwardly to the bottom of each microscler straight flute 4461 relatively.

When depressing handle 421, please referring to Fig. 4 and Figure 11, Figure 12, be to rotate turn-button 441 down in a clockwise direction with handle driving shaft 471, and the restoring force of opposing handle return spring 47 in the rotation process, can rotate toward the clockwise direction to save locating shaft 442 in twice trace 443 interlocks when turn-button 441 rotates instantly, spur trace 448 staggered actions on two simultaneously, last trace 448 with the right side is drop-down with track plate 446 and top sheave 445, make flush plate 444 towards counterclockwise direction rotation, drive the release knob seat 48 that together is incorporated into release knob 43 simultaneously and rotate towards counterclockwise direction;

When central joint locating shaft 442 rotates toward the clockwise direction, can promote 163 rotations of interlock swash plate with two buckle shapes 4421, contract in the oblique tongue 31 with the European multiple spot locker 30 of dwang 16 drives, and when release knob seat 48 when counterclockwise rotating, can drive tapered end driver plate 21 towards square tongue 33 withdrawals of counterclockwise rotating and make European multiple spot locker 30, therefore the action of the handle of depressing 421 not only can make each oblique tongue 31 retraction, also can untie the square tongue 33 of the state of going up that contracts, also lock to press by the once action of handle 421 by inside and just separate the effect that door bolt opens the door even reach square tongue 33, in the critical speed that can accelerate to escape.
