Description
Technical field
The utility model relates to a kind of locking device, relates in particular to a kind of double door locking device.
Background technology
More and more stricter for the requirement of bulk storage plant at present, require warehouse protection against the tide, fire prevention, windproof, insulation etc., yet barndoor gate all is the double door with doudle leaf door fan, the locking device of double door is just more single, fasten by lock hanging and lock nose between the doudle leaf door fan, hang up padlock again, this locking mode locking back door leaf is firm inadequately, when strong wind occurs, door leaf will acutely rock front and back, so just do not satisfy the requirement that some warehouses are windproof, be incubated, and door leaf acutely rocks the life-span and the safety that also can influence the gate.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of double door locking device is provided, and what this locking device can be very firm locks the doudle leaf door fan, avoids door leaf front and back to occur and acutely rocks, and has improved the safety and the application life of double door.
For solving the problems of the technologies described above, the technical solution of the utility model is: double door locking device, and comprising: at least two mount pads, described mount pad are fixed on one page door leaf of described double door; Locking bar, described locking bar rotates and is installed on the described mount pad; The lock hanging of coupling and lock nose mutually, described lock hanging is fixed on the described locking bar, and described lock nose is fixed on another page door leaf of double door; Described locking device also comprises antichattering system, and described antichattering system is installed on the closure place of described doudle leaf door fan.
Wherein, described antichattering system comprises: dead bolt, and described dead bolt is fixed in the end of described locking bar, and described dead bolt and lock hanging are positioned at the opposite side of described locking bar; Dead bolt seat, described dead bolt seat are fixed on the fixture and are positioned at the closure place of described doudle leaf door fan, and described dead bolt seat is provided with the locked groove that is used to hold described dead bolt, and described dead bolt is provided with an arc guide portion.
As a kind of improvement, also be fixed with the pressing plate that is used to compress another page door leaf on the described locking bar.
After having adopted technique scheme, effect of the present utility model is: double door locking device, and comprising: at least two mount pads, described mount pad are fixed on one page door leaf of described double door; Locking bar, described locking bar rotates and is installed on the described mount pad; The lock hanging of coupling and lock nose mutually, described lock hanging is fixed on the described locking bar, and described lock nose is fixed on another page door leaf of double door; Described locking device also comprises antichattering system, described antichattering system is installed on the closure place of described doudle leaf door fan, therefore, and when need close the door, rotating lock hanging makes lock hanging fasten the lock nose, hang up padlock, simultaneously, because the closed place of described doudle leaf door fan is equipped with antichattering system, therefore, antichattering system just can prevent from acutely to rock before and after the door leaf, thereby the safety and the application life of having improved barndoor gate are locked in very firm doudle leaf door is fanned.
Comprise owing to described antichattering system again: dead bolt, described dead bolt is fixed in the end of described locking bar, and described dead bolt and lock hanging are positioned at the opposite side of described locking bar; The dead bolt seat, described dead bolt seat is fixed on the fixture and is positioned at the closure place of described doudle leaf door fan, described dead bolt seat is provided with the locked groove that is used to hold described dead bolt, described dead bolt is provided with an arc guide portion, therefore, when closing the door, the direction that direction that lock hanging is rotated and dead bolt rotate is opposite, at door leaf when door hinge turns to closed place, locking bar drives dead bolt and rotates, because the effect of the guide portion of dead bolt, dead bolt is fixed in the locked groove of the dead bolt seat on the fixture with regard to very well snapping onto, like this, dead bolt is stuck in the locked groove, the lock hanging padlock on the lock nose, thereby make that door leaf locks very firmly, avoided the front and back of door leaf to rock, and when opening the door, break lock hanging off with the fingers and thumb, locking bar rotates and drives dead bolt simultaneously and rotate and rotate in the opposite direction, dead bolt is under the guiding function of guide portion, dead bolt backs down locked groove, and simultaneously, door leaf rotates, dead bolt just can break away from from locked groove like this, has realized opening the door.
Again owing to also be fixed with the pressing plate that is used to compress another page door leaf on the described locking bar, therefore, at closing time, except lock hanging padlock lock nose, pressing plate also compresses door leaf, thereby make the stressed balance more of door leaf even, avoid because the imbalance of switch strength causes damage to door-plate, the doudle leaf door fan is locked more firmly simultaneously.
