Description
Technical Field
The invention relates to a lockset, in particular to a rolling door ground lock.
Background
At present, the tool to lock on the rolling slats door is generally including installing the lock on the door body and fixing subaerial ground lock, and ground lock is mainly including ground lock casing and the locking lever of setting in ground lock casing, and the lock mainly is including the lock casing, the lock casing on correspondingly be provided with and insert when locking grafting portion in the ground lock casing, this grafting portion specifically is including two grafting feet, install between two grafting feet with the hasp that the locking lever was joined in marriage mutually, consequently for making things convenient for two grafting feet to insert, a jack has all been seted up to the up end of ground lock casing to corresponding in the both sides of locking lever, just ground lock casing corresponds and all is provided with a apron that is used for opening or seals this jack in every jack department. However, in the prior art, each cover plate is independently opened and closed, namely, the cover plate is opened only by being pressed, and the ground lock is arranged on the ground, and meanwhile, the jack and the cover plate are correspondingly positioned on the upper end surface of the ground lock shell, so that people can easily step on the ground lock by mistake when passing by the ground lock, and once the cover plate is stepped on, the cover plate is opened, so that particularly for some women wearing high-heeled shoes, the heels of the women can be stepped on the cover plate, and after the cover plate is opened, the heels can pass through the jack and sink into the ground lock shell, so that the people easily lose balance instantly to fall down and damage, and potential safety hazards exist.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the rolling door ground lock which can effectively avoid the accident caused by mistakenly stepping on the cover plate.
In order to achieve the above purpose, the invention provides a rolling door ground lock, which comprises a shell, wherein a lock rod is arranged in the shell, the upper end surface of the shell is provided with a jack corresponding to both sides of the lock rod, the shell is provided with a cover plate for opening or closing the jack corresponding to each jack, the two cover plates at the two jacks are hinged and fixed on the shell, each cover plate is provided with a side plate extending downwards, each side plate is provided with a groove, at least two support frames are arranged below the two cover plates, each support frame comprises a first support plate and a second support plate, the upper end of the first support plate on the same support frame is abutted against the side plate on one cover plate, the upper end of the second support plate on the same support frame is inserted into the groove of the side plate on the other cover plate, and a certain gap is kept between the upper end surface of the second support plate and the upper top surface of the groove, and when the cover plate is pressed to the upper top surface of the groove on the cover plate to be abutted against the upper end surface of the second support plate, the second supporting plate forms the limit for the cover plate to continue to hinge downwards, the first supporting plate and the second supporting plate on the same supporting frame are connected into a whole through a cross beam, the lower end of the first supporting plate and the lower end of the second supporting plate on the same supporting frame are hinged and fixed in the shell through the same supporting shaft, a spring which forces the first supporting plate to abut against the corresponding side edge plate is arranged between the first supporting plate and the side wall of the shell, when one cover plate is pressed and hinged downwards, the first support plate which is propped against the upper side plate of the cover plate is driven to be hinged and rotated against the action force of the spring, and when the first support plate is hinged and rotated against the action force of the spring, the upper end of a second supporting plate of the same supporting frame with the first supporting plate is rotated and separated from the groove of the other cover plate.
The invention has the beneficial effects that: by adopting the structure, when people step on one cover plate, because the upper top surface of the groove on the cover plate has a certain gap with the upper end surface of the second support plate inserted into the groove, the cover plate which is stepped on cannot be opened, but is only hinged downwards for a certain distance, namely the gap is compressed, after the gap is compressed, the upper top surface of the groove on the cover plate can be abutted against the upper end surface of the second support plate inserted into the groove, the second support plate can form the limit of the cover plate to continue to be hinged downwards, namely the cover plate which is stepped on cannot continue to be hinged downwards, so that the jack corresponding to the cover plate cannot be opened, further the risk of accidents caused by mistakenly stepping on the cover plate is effectively avoided, and the cover plate can push the first support plate abutted against the side plate to rotate in the process of slightly hinging downwards when the cover plate which is stepped on is downwards, after the first supporting plate is hinged and rotated, the upper end of a second supporting plate of the same supporting frame with the first supporting plate can be rotated and separated from the groove of the other cover plate, namely, at the moment, the other cover plate can be pressed and opened. In summary, with the structure provided by the invention, to open one cover plate, the other cover plate must be pressed to perform limiting unlocking before opening, that is, when only one cover plate is stepped on by misoperation, the stepped cover plate cannot be pressed to open, and at the moment, the other cover plate loses the limiting position, and can be pressed to open, thereby effectively avoiding the risk of accidents caused by mistaken stepping on the cover plate by people.
The invention can be further arranged in such a way that the left side and the right side of each cover plate are respectively provided with a side plate, the side plates on the left side and the right side are symmetrically arranged, the shell is internally provided with four supporting frames, four first supporting plates in the four supporting frames are respectively correspondingly abutted against the four side plates one by one, and four second supporting plates in the four supporting frames are respectively correspondingly inserted into grooves on the four side plates one by one. Thus, the structure is more symmetrical and reasonable.
The invention can be further provided with an arc-shaped bent part at the upper end of the first supporting plate, and the first supporting plate is abutted against the side edge plate of the cover plate through the arc-shaped bent part. By adopting the structure, the first supporting plate can be better hinged along with the pressing of the cover plate.
The invention can be further provided with a torsional spring which can promote the cover plate to seal the jack on the hinged shaft of the cover plate and the shell. The arrangement is that when the cover plate is not pressed, the cover plate automatically seals the jack under the action of the torsion spring.
