Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figures 1 to 6: the present invention includes grille body 1 and crank hand 2, breechblock 3, lower breechblock 4, upper stopper 5 and lower stopper 6 is also comprised;
Described grille body 1 comprises lock box 11, lock core 12, locking closure 13, gear shaft 14, tooth bar 15, reduction torsion spring 16, grille body 1 is fixed on an inner side, and lock core 12, gear shaft 14, tooth bar 15 and reduction torsion spring 16 are arranged on and snap together in the space that forms by lock box 11 and locking closure 13; Gear shaft 14 is installed reduction torsion spring 16, lock core 12 is provided with dead bolt 121, gear shaft 14 is fixed with block 141, carries out spacing by dead bolt 121 with coordinating of block 141 to gear shaft 14; Described tooth bar 15 is two and be arranged in parallel, and two tooth bars 15 engage with gear shaft 14 respectively, is installed with a breechblock contiguous block 17 below each tooth bar 15;
Crank hand 2 is arranged on outer side of door, and crank hand 2 is connected to gear shaft 14, and upper breechblock 3 and lower breechblock 4 are connected to a breechblock contiguous block 17, and upper stopper 5 and lower stopper 6 are arranged on upper door frame and lower door frame respectively.
Upper breechblock 3 and lower breechblock 4 are positioned on same axis; Upper breechblock 3 and lower breechblock 4 insert in a guide pad 7 respectively, two guide pads 7 are arranged on side door, and be positioned on same axis with upper breechblock 3 and lower breechblock 4, make direction in breechblock 3 and lower breechblock 4 moving process constant, and the level and smooth movement of breechblock 3 and lower breechblock 4 can be realized well, avoid occurring stuck phenomenon, simultaneously, guide pad 7 can adopt nylon material, and such friction system is little, makes the unlatching leicht fallen D/A more of side door.
Described two breechblock contiguous blocks 17 contact, one of them breechblock contiguous block 17 is provided with slide rail, another breechblock contiguous block 17 has guide groove, two breechblock contiguous blocks 17 are connected with guide groove by slide rail, when gear shaft 14 rotates, two tooth bars 15 do rightabout slip along slide rail, and this mode makes the slipping smoothness of two tooth bars 15, fluent phenomenon.
Locking closure 13 has four holes, the position that lock box 11 matches with hole is provided with four hollow shafts, and the interference fit between lock box 11 and locking closure 13 passing hole axle links together; Sealed by weather strip between lock box 11 and locking closure 13, make whole grille body 1 seal tight, internal lubrication oil not easy to leak.
One end that upper breechblock 3 coordinates with upper stopper 5 is wedge shape; One end that lower breechblock 4 coordinates with lower stopper 6 is wedge shape, and this setup both facilitated, and makes again side door firmly be not easy to rock.
Lock box 11 inside is fixed with carries out spacing limited block 151 to tooth bar 15, carries out accurate limit to the stroke of tooth bar 15, prevents crank hand 2 rotational angle excessive, is damaged by reduction torsion spring 16.
Crank hand 2 and gear shaft 14 are by pinned connection, thus the dismounting of convenient door lock body 1.
Embodiment: as shown in the figure, the present invention in use, first grille body 1, upper breechblock 3 and lower breechblock 4 are assembled together, then be arranged on together inside side door, crank hand 2 is arranged on outside side door, use guide pad 7 respectively to upper breechblock 3 and the restriction of lower breechblock 4 travel direction, breechblock 3 and lower breechblock 4 can only be moved on the same axis.
When side door is in normally off, dead bolt 121 on lock core 12 contacts with block 141, the rotation of dead bolt 121 pairs of gear shafts 14 provides constraints, gear shaft 14 cannot rotate, upper breechblock 3 and lower breechblock 4 cannot be retracted, and when without External Force Acting, the torsion of reduction torsion spring 16 also can make breechblock 3 and lower breechblock 4 be in the state of stretching out all the time and not rock, upper breechblock 3 and lower breechblock 4 end are inserted in stopper 5 and lower stopper 6 respectively, under the common restriction of reduction torsion spring 16 and dead bolt 121, side door lock death jail by, do not rock.
When side door need be opened, only with key, lock core 12 need be rotated counterclockwise, the block 141 on gear shaft 14 is made to depart from the restriction of dead bolt 121, then crank hand 2 is rotated clockwise, upper breechblock 3 and lower breechblock 4 are retracted under the drive of tooth bar 15, upper breechblock 3 and lower breechblock 4 depart from the restriction of stopper 5 and lower stopper 6 respectively, can realize side door and open.
