The purpose of this utility model provides a kind of Three-bearing safe-guard door lock, and it is simple in structure, compact, reliable, the material saving, volume is little, easy to use, theftproof is good.
The utility model is achieved in that a kind of Three-bearing safe-guard door lock, have cover plate and the lock housing that is connected with panel, it is characterized in that being equipped with in the lock housing activity connection sheet of 2 tape guide grooves, the axis of guide on gathering sill and the housing matches, the axis of guide is provided with the dead bolt back-moving spring, on 2 bolsters of housing 2 forks are housed, the driving shaft of fork one end, match with the driver slot of connection sheet, the other end of 2 forks is equipped with the dead bolt drive hole, and two holes can be overlapping up and down, and holder links to each other the dead bolt in the panel hole with tongue, the tongue holder is provided with driving shaft, insurance block and lock-switch block, driving shaft is provided with tongue holder guide frame and safety plate fixed axis in the housing in the drive hole of fork, the safety plate and the safety plate garter spring of band guide rail is housed on this, be provided with tapered end near the tongue holder, tapered end is provided with the holder of safety plate tongue and stirs cam.
Can also be following structure, promptly on the basis of said structure, the tongue holder be provided with dial axis, handgrip is housed on the housing, and handgrip links to each other with sliding piece, links to each other with the dead bolt retraction slot at the dead bolt drive hole of the other end of 2 forks, claim dead bolt to drive retraction slot, it matches with driving shaft in the tongue holder.The dead bolt of the structure above this kind structure dead bolt is comparable is long, and after lock was opened, slow-witted tongue promptly became the tongue that bumps alive, and armrest bumps the tongue indentation making to live again, and door is opened.
Tapered end in above-mentioned two kinds of structures can be the monolock head, also can be the twin-lock head of separate type, and is simple and reliable for structure for making, and preferably uses disjunctor twin-lock head.
Through on probation, above-mentioned two kinds of structures of the present utility model have all that structure is ingenious, simple, compact, volume is little, material saving, cost are low, reliable, easy to install, motion flexibly, advantages such as the firm and durable theftproof is good, especially single tongue multifunction structure has more the fabulous characteristics of usability.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing, but not as to qualification of the present utility model.
Fig. 1 is the structural representation of an embodiment of single tongue Mobyneb.
Among the figure, panel 1 links to each other by screw 31 with lock housing 8, cover plate figure part omitted, movable connection sheet 5, the axis of guide 4 on gathering sill on 26 and the housing 8,27 match, the axis of guide 7 is provided with dead bolt back-moving spring 6, two bolsters 10 on the housing 8, two forks 9 are housed on 24,25, fork 9, the driving shaft 4 that 25 1 ends are provided with, 27 and the connection sheet 5, driver slot on 26 (shown in the dotted line) cooperates, fork 9,25 the other end is equipped with dead bolt and drives retraction slot (shown in the dotted line), two grooves can be overlapping up and down, dead bolt 2 in panel 1 hole links to each other with tongue holder 3 by sunk screw 32, tongue holder 3 is provided with driving shaft 14, dial axis 16, insurance block 15 and lock-switch block 21, driving shaft 14 and driving retraction slot match, and 19 is tongue holder gathering sill (or being other guiding mechanisms).Housing 8 is provided with safety plate fixed axis 18, this is equipped with the safety plate 20 and the safety plate garter spring 17 of band guide rail, be provided with disjunctor twin-lock head 22 near the tongue holder 3, tapered end is provided with stirs cam 23, handgrip 13 is housed on the housing 8, handgrip 13 links to each other with sliding piece 11, housing 8 is provided with sliding piece back-moving spring 12, tongue bar or pin 30 link to each other with connection sheet 26,5 by trip bolt 29, when locking a door, the key cam rotation is at first opened safety plate, drive the outside motion of tongue holder then and reach the Three-bearing locked position, this moment, safety plate was locked the tongue holder; When opening the door, the backward rotation key is at first opened to protect and is removed sheet, then the tongue holder is dialled back, and the insurance block 15 of safety plate blocks the tongue holder, and it is gone out, and at this moment, slow-witted tongue has become work and bumped tongue, can work the effect of sealing up a door, and stirs with key or handgrip and opens the door.Because during locking, dead bolt has stretched out two strokes, as 25mm, so when crack between a door and its frame is big, this lock is much more firm than other like products, simultaneously, because dead bolt can strengthen lengthening, the many usefulness of one tongue so overcome the two shortcomings that the tongue structure dead bolt is little, intensity is low of like product, have improved dead bolt intensity.
