Under the state of second figure, this pressing piece 152 is not subjected to pushing of external force and is positioned on the position of stretching out, the door bolt of described lock body 10 34 is positioned at the upper lock position of the end face 24 that stretches out door 20, and door bolt 34 penetrates and makes door 20 present locking state in the frame 21 can't to open, described drive bar 113 is resisted against the first end 73 of stopper slot 71, and described limited part 136 provides linking part 64 at driving lever 104, under the state that connecting rod 118 and adjustment part 144 all do not move, can not rotate for the axle center according to driving bar 113 separately, these roller 132 stable being resisted against are affected on the part 36.
The application of force promotes pressing piece 152 under the second figure state, can make condenses in pressing piece 152 opposite shell 150 moves, is that rotate in the axle center and promote traction pieces 154 with first jiao of end 156 according to the pivoting point of third angle end 160, second jiao of end 158 rotated to the left side that with second figure is direction, spur connecting rod 118 simultaneously to left dislocation, the interlock end 120 of this connecting rod 118 is that rotate in the axle center with pivoted pole 134 pulling driving levers 104 according to driving bar 113, it is that the axle center turns left according to fixed bar 100 that second axis hole 126 of described connecting rod 118 drives limited part 136 with axostylus axostyle 142, second end 108 of driving lever 104 also bears left moving with roller 132, and interlock affects part 36 and door bolt 34, make door bolt 34 by contracting in the upper lock position to the unlocked position that breaks away from frame 21, the state of formation shown in the 7th figure, and in the above-mentioned unlocking operation process, because adjusting lever 90 does not rotate, so adjustment part 144 can't be done axial displacement.
Consult shown in second figure, the fixing hole 112 of this driving lever 104 to the online distance definition in the center in pivot hole 116 is first distance L
1(about 40.67mm), this fixing hole 112 to the online distance definition at combined hole 114 centers is second distance L
2(about 63mm), this second distance L
2Length greater than first distance L
1, and the online distance at aforementioned these these each 116 center, pivot hole to each fixing hole 112 centers as can be known of foundation so designs and can make second distance L greater than the online distance at each 116 center, pivot hole to each combined hole 114 center
2With first distance L
1Ratio less than 2, it mainly is because connecting rod 118 design has turn section 123, this turn section 123 to make the pivot points of interlock end 120 and driving lever 104 near second end 108, and with first distance L
1With second distance L
2Length difference dwindle, make operation pressing piece 152 make strength required when contracting in the door bolt 34 less, obtain preferable operating handle by this.
Moreover, these each default on 20 locating hole 29 positions can influence the installation site of driving mechanism 12 relative lock bodies 10, state that may be shown in the 8th figure when therefore this driving mechanism 12 is installed, because the close end face 24 that locating hole 29 is provided with, also close end face after making driving mechanism 12 install, make roller 132 to be resisted against and affect on the part 36, when promoting pressing piece 152 releases, this driving lever 104 has one section rotation distance does not have the idle stroke that interlock affects part 36, therefore affect the shift length of part 36 can be less than the distance under the second figure state, this shift length is not enough can to make door bolt 34 contract in can't be fully, the state of formation shown in the 9th figure, the part of this door bolt 34 still can be stuck in the frame 21, and can't open door 20 smoothly.
This creation is provided at and eliminates roller 132 and the adjustment function that affects part 36 gaps under the state shown in the 8th figure, promptly under the state shown in the 8th figure, can rotate adjusting lever 90, this adjusting lever 90 rotates its screw thread can order about adjustment part 144 along its axial displacement, if make of first end 73 past the second end 75 displacements (drive bar 113 also toward the second end 75 displacements) of this adjustment part 144 by stopper slot 71, second end 108 of this driving lever 104 will be toward affecting part 36 to rotate (rotate on the left side to the graphic direction of the 8th figure), therefore can be adjusted to and roller 132 is resisted against affect on the part 36, the aspect of formation shown in the tenth figure, eliminate roller 132 and the spacing that affects part 36, so this driving lever 104 drives and affects part 36 just not have idle stroke, make and affect the enough distances of part 36 displacements, then the interior retraction unlocked position that door bolt 34 can be complete can be opened door 20 smoothly.
Graphic and the disclosed content of manual of this creation; be the known at that time most preferred embodiment of application; its purpose only is used to help to understand the technical characterictic of this creation; and should not be used to limit the request claim of this creation; be to know the variation enforcement that other also can be arranged under the technical characterictic of this creation; for example this driving mechanism 12 still can be operated driving lever 104 and makes in the door bolt 34 and contract to unlocked position under the state that is not provided with limited part 136; or this support 46 can directly be installed on the side 22 of door 20; not needing to see through pedestal 38 links with door 20; or the quantity of the assembly of other this creation exposure; the simple and easy variation of size or shape or alternative; easy variation like that is implemented, and all belongs to the protection domain of this creation.
