Description
Technical field
This utility model relates to antitheft door technical field, particularly relates to a kind of novel middle control latch.
Background technology
Existing biparting class antitheft door, namely there is main door leaf and the antitheft door of secondary door leaf, in actual use, except there being special requirement just by except fully open for bivalve door, all the other are in most cases, generally all only switch with main door, and pair door is all fixed on doorframe by latch (universal pin) at ordinary times, and on latch is generally all, lower two independent latches, need to regulate upper and lower latch respectively when opening or lock secondary door, and outside latch is exposed to, namely unsightly, operation is also inconvenient, needs are started to scratch and are stuck up latch, the locking with doorframe could be released, cause high effort for.
Utility model content
This utility model provides a kind of novel middle control latch, and the latch solved in prior art on door, because being upper and lower two independent latches, in use exists above-mentioned circumscribed problem.
This utility model realizes above-mentioned technique effect and be the technical scheme is that
A kind of novel middle control latch, including fixing seat, the universal pin being positioned on the upper and lower two ends of door, for driving the link gear and connecting rod that the universal pin on the upper and lower two ends of door moves, described linkage structure is arranged in fixing seat, the both sides of described link gear are respectively connected to a connecting rod, one end of described connecting rod is connected with universal pin, the other end is connected with link gear, drives connecting rod to move up and down thus driving universal pin to move up and down by link gear；
Described link gear includes rotating shaft, gear and is positioned at two tooth bars that gear both sides are engaged with gear respectively, and described rotating shaft is fixing with gear to be connected, and one end of described connecting rod is fixing with tooth bar to be connected.
Further, described gear and tooth bar be provided above fixing device, described fixing device includes stator and is arranged on above stator and fixes the pad being connected with roller end, and the effect of fixing device is in that to prevent tooth bar from pitching.
Further, the end of described rotating shaft is provided with groove, rotates described rotating shaft for convenient.
After installation, the exposed outside at door body side of described rotating shaft, by key or other are according in the groove inserted in rotating shaft, rotate described rotating shaft, the rack synchronous driving both sides while gear concomitant rotation moves up and down, and then drive the universal pin at upper and lower two ends to move up and down, it is achieved door body fixing on doorframe.
The beneficial effects of the utility model are: the novel middle control latch of one of the present utility model, adopt link gear to drive two universal pins up and down in door body to be synchronized with the movement, it is achieved door body fixing on doorframe, and simple in construction is convenient and practical.
