Abstract
A double-leaf door lock is composed of main and auxiliary lock shells, and the locking mechanism in main lock shell is composed of lock bolt shell, two lock bolt levers with sector gear and engaged with each other and restoring spring. The opening, the safety and the limit of the bolt retraction are all completed by the frame mechanism, the number of parts is reduced by 8-10, and the positioning is accurate and the use is convenient.
Description
The utility model is a kind of improved double door latch.
The patent No. is the double door latch of CN862064023, and its opening mechanism, insurance institution and the position-limit mechanism of dead bolt withdrawal respectively become a cover, and dead bolt is emitted the ancient button form that adopts, complex structure, and the location is inaccurate.
The purpose of this utility model is to provide a kind of limit function with open function, insurance function and dead bolt withdrawal altogether, the double door latch of being finished by a frame mechanism.
Fig. 1 is the latch locking state structural representation of opening behind the protecgulum.
Fig. 2 is after latch is opened, the schematic diagram of dead bolt lever.
Fig. 3 is all schematic diagrames of the main lock housing body of withdrawal of dead bolt shell.
Fig. 4 is a dead bolt leverage schematic diagram after latch is insured by turn-knob.
Fig. 5 is the whole rear elevation of latch.
Below in conjunction with accompanying drawing the design is described in detail.
Latch is divided into main lock housing body 1 and secondary lock housing body 2, main lock housing body 1 is made up of the protecgulum of core with lock and the bonnet and the retaining mechanism of band turn-knob 3, retaining mechanism is to have sector gear 5 and intermeshing dead bolt lever 6 by dead bolt shell 4 and two, 7 and reverse spring form, lever 6,7 front end is respectively upper lock tongue 8 and following dead bolt 9, the fulcrum of lever is fixed on the dead bolt shell 4 by pin 10, dead bolt shell 4 side-to-side movement on the track support 12 that spring 11 is housed, the afterbody that it is characterized in that lever 6 has one and the corresponding protruding column 13 of plectrum of lock core, the afterbody of lever 7 has one and plectrum 14 corresponding " window formula " frame mechanism 15 of turn-knob 3, projection 16 on the plectrum 14 is positioned at " window " of frame mechanism 15, be in the hollow of framework, and can move along one section edge of " window ", to reach unlatching, insurance, the function that the dead bolt withdrawal is spacing.Projection 16 is along the bending section with certain radian 18 of a notch that has radian 17 that safety effect has been arranged on mobile section of frame mechanism 15 and a position-limiting action, and bending section 18 is provided with spacing point.
At closing time, dead bolt shell 4 should stretch out main lock housing body 1, as long as smoothly door is closed, dead bolt 8,9 relies on the impact force of closing door to enter in the dead bolt hole of secondary lock housing body 2, and door has just been shut.
When opening the door, the people inserts lock core (general lock cylinder is just) and clockwise rotates at the outdoor use key, and the tail protrusion cylinder 13 of the plectrum shifting lever 6 on the lock core makes lever 6,7 motions, dead bolt 8,9 withdrawal dead bolt shells 4, and door has just been opened.The people when utilizing turn-knob 3 to open the door, clockwise rotates turn-knob 3 indoor, makes the projection 16 on the plectrum 14 that is positioned at frame mechanism 15 drive frame mechanisms 15 motions; And then make lever 7 to motion on one side, since the engagement of gear 5, two dead bolt 8,9 withdrawal dead bolt shells 4, and door is just opened.
When insuring, rotating counterclockwise 360 ° of keys outdoors, then the lock core plectrum is stuck on the tail protrusion cylinder 13 of lever 6, because the self-locking action of lock core is not opened door at indoor rotation turn-knob 3 yet.If insure indoor, can rotate counterclockwise turn-knob 3, impel projection 16 on the plectrum 14 to move in the notch 17 on the frame mechanism 15, lever 6,7 can not be rotated around fulcrum, at this moment do not open door at the outdoor use key yet.
Door is being opened the people when at will coming in and going out, as long as clockwise rotate turn-knob 3, projection 16 on the plectrum 14 at first makes frame mechanism 15 to a motion, in dead bolt 8, the 9 withdrawal dead bolt shells 4, then continue to clockwise rotate turn-knob 3, make frame mechanism 15 and lever 6,7 continue to shrink back backward, when projection 16 is positioned at the dead point of bending section 18, be automatic spacing, in the main lock housing body 1 of dead bolt shell 4 whole withdrawals.Need at closing time, as long as rotate counterclockwise turn-knob 3 slightly, dead bolt shell 4 relies on reverse spring just to emit automatically.
The utility model has been owing to increased by a frame mechanism at the afterbody of a dead bolt lever, spacing formation one overall structure that makes unlatching, insurance and dead bolt withdrawal, and mechanism is simple, and part has reduced 8-10, and accurate positioning, and is easy to use.
Claims (2)
1, a kind of double door latch, form by main lock housing body and secondary lock housing body, main lock housing body is made up of the protecgulum of core with lock and the bonnet and the retaining mechanism of band turn-knob, retaining mechanism has sector gear and intermeshing dead bolt lever and reverse spring by dead bolt shell and two and forms, the front end of two levers is respectively upper lock tongue and following dead bolt, the fulcrum of lever by dowel fixes on the dead bolt shell, the dead bolt shell moves being equipped with on the track of spring, the afterbody that it is characterized in that a lever has one and the corresponding frame mechanism of turn-knob plectrum, projection on the turn-knob plectrum is positioned at the hollow of frame mechanism, and can move along one section edge of frame mechanism, the notch that has radian of safety effect and the bending section with certain radian of a position-limiting action have been arranged on mobile section of frame mechanism, and bending section is provided with spacing point.
2, double door latch as claimed in claim 1, the afterbody that it is characterized in that another lever have one and the corresponding protruding column of lock core plectrum.
