Description
Technical field
The present invention relates to door and window manufacturing field, more particularly to a kind of automatic plug for door device.
Background technology
At present, the common opposite opened door of in the market by doorframe, two fan doors, main lockset, day lock, lock, installed in door frame
Tongue hole composition；The structure of two fan doors is that main lockset is set on Yishanmen, and hereinafter referred to as master locks a door, and is set on another Yishanmen and main
Main lockset hole corresponding to lockset, day lock mounting hole, lock mounting hole, hereinafter referred to as pair is locked a door；My god, lock and be separately mounted to pair and lock a door
On day, lock in mounting hole, day lock, lock for bolt-type, it is necessary to respectively the upper and lower day of control manually, the latch ability locked
Pair is locked a door and locked.When opposite opened door needs to close, operation order is the dead bolt for the ground lock and day lock that first pair is locked a door
The tongue hole being aligned on doorframe, then stir day lock, the switch locked, dead bolt is embedded into tongue hole, so as to which pair be locked a door
It is fixed on doorframe, finally closes master and lock a door, reach the effect closed.If necessary to fan doors all the two of the opposite opened door closed
During opening, operation order be need first then to stir main openings of locking a door again the day on secondary lock a door, the switch locked so that
Dead bolt is spun off from dead bolt hole, and pair, which is locked a door, to be released, and two fan doors could be fully open.This operation step for opening and closing door
It is rapid more, open the door, close the door it is not convenient, quick.How a kind of bolt device is designed so that the simplification the problem of being one to be solved of opening the door,
For this China Patent No.：201020678605.3 disclose a kind of semi-automatic inserted pin device for double-leaf door, including biparting door frame and
Two fan door leafs (A3,8) being installed on doorframe, it is characterised in that:It is equipped with door leaf (A3) by controlling organization (A5), drive link
(A4), the bolt device of bolt mechanism (A1) composition, the pin hole coordinated with bolt mechanism (A1) is provided with doorframe;Controlling organization
(A5) by the rotary body (4) that is horizontally installed on door leaf (A3) and it is fixed on the linkage block (9) of rotary body (4) both sides and forms;Insert
Pin mechanism (A1) is by the latch fixed mount (21) being fixed on door leaf (A3) and the latch being installed on latch fixed mount (21)
(14,15) form;One end of one of drive link (A4) is movably connected in the linkage block (9) of side, and the other end is connected to
On top latch (14,15);One end of another drive link (A4) is movably connected in the linkage block (9) of opposite side, the other end
It is connected on bottom latch (14,15).And for example China Patent No.：201620526089.X a kind of bolt device is disclosed, in order to
Overcome the shortcomings that opposite opened door opens the door, door-closing operation step is more, not convenient in the prior art, the utility model provides such one
Kind of bolt device, include secondary locking device, latch assembly I, latch assembly II and installed in the tongue hole of door frame；Secondary locking device
It is connected respectively with latch assembly I, latch assembly II；Secondary locking device includes secondary lock housing body, telescopic component, oscillating rod elastic force group
Part, door leaf elastic component and extension spring.Beneficial effect：When wanting door-closing operation when door is in opening, first pair is locked a door closing, led to
Telescopic component, latch assembly I, latch assembly II is crossed to insert dead bolt in tongue hole；Main door is closed again, realizes the behaviour of shutdown
Make quick and easy；Opening door operation, it is only necessary to which after main opening of locking a door, revolute handle of locking a door can open door, realize two
Door is fanned to open.But both the above structure is still to manually opened, and structure is complex, and cost is higher.
The content of the invention
Therefore, for it is above-mentioned the problem of, the present invention propose it is a kind of it is simple in construction, cost is low, it is easy to use, can be automatic
