Description
Technical field
The present invention relates to a kind of lockset, and in particular to a kind of floor lock for rolling shutter door.
Background technology
At present, the lockset in rolling screen door generally comprises the door lock in door body and the ground fixed on the ground lock, ground
The locking bar that lock mainly includes ground lock housing body and is arranged in ground lock housing body, door lock mainly includes door shell, described door
The plug division inserted when locking in described ground lock housing body is correspondingly provided with lock housing body, the plug division has specifically included two grafting
The lock mutually locked and matched somebody with somebody with locking bar is equiped between pin, two inserting foots, therefore for convenience of the insertion of two inserting foots, the upper end of ground lock housing body
Face correspondence offers a jack in the both sides of locking bar, and lock housing body correspondence in described ground is provided with a use at each jack
In the cover plate for opening or closing the jack.But in the prior art, each cover plate is independent opening and closing, as long as i.e. cover plate
It is pressurized, the cover plate will be opened, and because ground lock is to install on the ground, meanwhile, jack is corresponding with cover plate to be located at ground lock housing
On the upper surface of body, therefore people are easy to lock with stepping on by mistake when locking place with passing by, once and cover plate stepped on, the cover plate is just
It can be opened, so that the women worn high heels especially for some, its heel is once stepped on the cover board, after cover plate is opened, heel
It will be trapped in ground lock housing body by jack, so that easily cause people occurs Fall injuries in moment disequilibrium, deposit
In potential safety hazard.
The content of the invention
In view of the shortcomings of the prior art, people can be prevented effectively from the invention provides one kind and occurs accident because stepping on cover plate by mistake
Floor lock for rolling shutter door.
To achieve the above object, the invention provides a kind of floor lock for rolling shutter door, include and installed in housing, described housing
There is locking bar, the housing upper surface correspondence offers a jack in the both sides of locking bar, and housing correspondence is in each jack
Two cover plates that place is provided with a cover plate for being used to opening or closing the jack, two jacks are hingedly fixed in housing
On, it is provided with each cover plate on the side board extended downwardly, each side board and is provided with a groove, under two cover plate
Side is provided with least two support frames, and each support frame includes first supporting plate and second supporting plate, same
The first supporting plate upper end on support frame leans with side plate on the upside of one of cover plate, the second supporting plate on same support frame
Upper end is inserted on the upside of another cover plate in the groove of side plate, and the upper surface of second supporting plate is kept with top surface on the groove
Certain interval, and when cover plate is pressed into the upper top surface of groove thereon and the upper surface of the second supporting plate is abutted against, described
Two supporting plates, which are constituted, continues the first supporting plate on the downward limitation for being hinged rotation, same support frame and second to the cover plate
Linked into an integrated entity between fagging by crossbeam, the first supporting plate lower end and the second supporting plate lower end on same support frame pass through same
One support shaft is hingedly fixed in housing, be provided between first supporting plate and housing sidewall force first supporting plate with
Respective side plate shape into against spring, and when one of cover plate is pushed to down and is hinged rotation, drive and its upper side edge
The first supporting plate that plate leans overcomes acting force of the spring to be hinged rotation, and turns when the first supporting plate overcomes acting force of the spring to be hinged
After dynamic, abjection is rotated out of another cover plate groove with the second supporting plate upper end of the same support frame of the first supporting plate.
The beneficial effects of the invention are as follows：Using said structure, when people are stepped down on a cover plate, due to the cover plate fovea superior
The upper top surface of groove only has certain interval, therefore this cover plate stepped on the second supporting plate upper surface being inserted into the groove
It will not be opened, and simply somewhat be hinged some distances of rotation downwards, that is, compress above-mentioned gap, after gap is compressed, the lid
Top surface can be constituted with the upper surface for the second supporting plate being inserted into the groove and abutted at once on groove on plate, second support
Plate will be constituted to be continued to be hinged the limitation of rotation downwards to the cover plate, that is, this cover plate of being stepped on can not continue to be hinged downwards and turn
It is dynamic, so that the jack corresponding with the cover plate would not also be opened, and then it effectively prevent people and occur because stepping on cover plate by mistake
Unexpected risk, and rotation is somewhat hinged downwards a little during in this cover plate stepped on, the cover plate can be promoted
The first supporting plate leant with its side board is hinged rotation, and first supporting plate is hinged after rotation, with the same branch of the supporting plate
Second supporting plate upper end of support can rotate abjection out of another cover plate groove, i.e., now, another cover plate can by by
Pressure is opened.In summary, using structure provided by the present invention, want to open a cover plate, it is necessary to first press another cover plate
Spacing unblock is carried out to it, could then be opened, i.e., when only one of which cover plate, which is misused, steps on, this cover plate stepped on
It is that will not be pressed opening, and now another cover plate loses spacing, then can be pressed opening, so as to effectively prevent people
Unexpected risk occurs because stepping on cover plate by mistake.
The left and right sides that the present invention can be further arranged to each cover plate is provided with a side board, and the side of the left and right sides
Side plate is symmetrical set, and four the first supporting plates difference in four support frames, four support frames is provided with described housing
Constituted with four side boards correspond against, four the second supporting plates in four support frames respectively with four side boards
Groove, which is constituted, corresponds grafting.In this way, structure is more symmetrical reasonable.
The present invention may further be provided is provided with arc kink, and described first for the upper end of first supporting plate
Supporting plate by the formation of the side board of the arc kink and cover plate against.Using said structure, first can be better achieved
Fagging is hinged rotation with the pressing of cover plate.
The present invention, which may further be provided to be additionally provided with the jointed shaft for cover plate and housing, promotes cover plate to carry out jack
The torsion spring of closing.In this way, when cover plate is not pressed, the cover plate is sealed to jack automatically in the presence of torsion spring
Close.
