Abstract
The utility model discloses two tongue safe-guard door lock constructions of switch after a kind of improvement, by the construction of switch of traditional inserting-core lock and the supporting form safe-guard door lock of many dead bolts master lock body, change over by manual knob composite member in shift fork, door, latch bolt composite member, connect the portable safe-guard door lock construction of switch that support bar and two tongues assemble; Be characterized in simple and practical, part is few, and the pellet number in addition in lock core reaches more than 30, improves anti-technical opening and the violence open function of lock body, the ultra-wide dead bolt of its uniqueness with move in parallel lock core disjunctor; Do not need to rotate after key outdoors inserts lock core, upper handle realizes that ultra-wide dead bolt is locked, pressed down that handle ultra-wide dead bolt is unblanked, two latch design of super practicality are novel, convenient to use, more can reduce a large amount of production raw material, manufacturing process and reduction recruitment cost.
Description
Technical field
The utility model relates to the safe-guard door lock construction of switch of traditional inserting-core lock and the supporting form of mechanical lock, two tongue safe-guard door lock constructions of switch after especially a kind of improvement.
Background technology
Known traditional safe-guard door lock is made up of inserting-core lock and the independent part of frame for movement master lock body two, and its main frame mode is; Key controls the shifting block action on inserting-core lock, again by shifting block stir part in master lock body drive dead bolt into and out of the control realizing opposite house, this form supporting by two or more part interlock, be actually and simple thing is complicated, in addition shifting block manufactures with powder metallurgy, easily broken crisp when using for a long time and be subject to large resistance, be easy to cause security door to open, and the supporting form of inserting-core lock and frame for movement master lock body has the use history of last 100 years; And their production process just has 120 multiple tracks, raw material, energy ezpenditure, add the recruitment cost etc. increased year by year, so just make whole lockset industry create cost of production more and more higher, and this bad phenomenon that the profit of manufacturer is more and more lower.
Utility model content
For the present situation of the supporting mode of the safe-guard door lock that above decades are constant and whole industry, the utility model is proposed two tongue safe-guard door lock constructions of switch after a kind of improvement.
The utility model solves the technical scheme that its technical problem adopts: first to traditional part stirred in master lock body by shifting block drive dead bolt into and out of mode improve, safe-guard door lock construction of switch is assembled into by manual knob composite member, latch bolt composite member, connection support bar and two tongues in shift fork, door, this two tongues safe-guard door lock construction of switch is novel in design, structure is simple, allows the use more convenient and quicker of lockset.
Its internal construction of further elaboration and mode of occupation, shift fork medium position after improvement is opened has bar-shaped trough and handle square rod jack to be an entirety, the connection support bar supporting with it, one end are fixed on the upper end of ultra-wide dead bolt, and the other end is arranged in the bar-shaped trough on shift fork.
Carry on after inserting key outdoors, press down the action of handle drive shift fork promotion connection support bar, realize the control of opposite house; In door, manual control manual knob composite member controls latch bolt composite member, realizes the control of opposite house.When in door, either party realizes locking outdoors time, handle in door, outdoors has just been fixed simultaneously.
The beneficial effects of the utility model are; Subtract and remove inserting-core lock, by manual knob composite member in shift fork, door, latch bolt composite member, connect the two tongue safe-guard door locks that support bar and two tongues are assembled into, structure is simple, cooperation transmission in lock body between part lacked; Marble amount particularly in lock core reaches more than 30, improves the anti-technical opening function of lockset; Also allow the use of lockset safer, convenient, due to whole, lockset part also more can be saved a large amount of raw material, energy, production process and reduction recruitment cost less.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, more detailed elaboration is done to the utility model.
Front panorama sketch when Fig. 1 the utility model is locked outdoors
Front panorama sketch when locking in Fig. 2 the utility model door
In Fig. 3 the utility model door, outdoors latch bolt open front view
In figure 1, marble hole main body 2, inner wall 3, move in parallel manual knob composite member 8 in lock core 4, ultra-wide dead bolt 5, main panel 6, shift fork 7, door, latch bolt composite member 9, connect support bar 10, handle square rod jack 11, key hole 12, be mounted with screw hole 13, exterior wall
Detailed description of the invention
In the embodiment shown in fig. 1, inner wall 2 fixes marble hole main body 1, moves in parallel key hole 11 in lock core 3 in the front end of marble hole main body 1; Ultra-wide dead bolt 4 major part is stretched out in the outside of main panel 5, connect the projecting point (upper end) that ultra-wide dead bolt 4 is fixed in the front end of support bar 9; When key extract up/down pellet in rear lock core pin move in parallel lock core 3, ultra-wide dead bolt 4 is locked simultaneously, now shift fork 6 not stretchy ultra-wide dead bolt 4 retreat, handle is also fixed, and lock body is locking state.
In Fig. 2 embodiment, ultra-wide dead bolt 4 is return after main panel 5, key hole 11 also synchronously returns to marble hole main body 1 rear end, ultra-wide dead bolt 4 is unlocking condition, in door manual knob composite member 7 upper end withstand on the rear end of latch bolt composite member 8, shift fork 6 just not stretchy latch bolt composite member 8 retreat, handle is also fixed simultaneously, achieves in door and locks.
In Fig. 3 embodiment, ultra-wide dead bolt 4 is return after main panel 5, the rear end of latch bolt composite member 8 is not blocked by the upper end of manual knob composite member 7 in door, and now door inside/outside handle can drive shift fork 6 to promote latch bolt composite member 8 to retreat, and realizes in door, opens the door outdoors.
