Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to Fig. 1 to Fig. 5, the embodiment of the present invention includes: a kind of key expander, including:
One housing 1, described housing 1 is rectangle, and the opposite side that described housing 1 is relative is outwards provided with fixed plate 5, and described fixed plate 5 is provided with fixing hole 6, and described housing 1 is fixed on door by described fixed plate 5 by described fixing hole 6.
Being provided with a main lockhole 7 at described fixed plate 5 in described housing 1, be provided with some be arranged in described fixed plate 5 parallel secondary lockhole 8, described main lockhole 7 and the described secondary lockhole 8 relative with described main lockhole 7 is used for placing main lock and secondary lock.
The center, long limit that described housing 1 is relative is inwardly provided with slide block limiting plate 9, described slide block limiting plate 9 is for by spacing for described slide block 4 horizontal plane, it is made to slide on the vertical plane, described slide block limiting plate 9 serves the function of locking closure, but the material of required making the most greatly reduces, more save material, repair replacing convenient.
Some lock cores 2, described lock core is provided with rotating shaft 10, described lock core 2 includes main lock core and auxiliary lock core, described main lock core and described auxiliary lock core are respectively arranged in described main lockhole 7 and described secondary lockhole 8, described auxiliary lock core is identical with the quantity of described secondary lockhole 8, and quantity is more than or equal to 2, considerably increases its wide usage.
Some dead bolts 3, described dead bolt 3 is provided with rotating shaft connecting hole 11, and described rotating shaft connecting hole 11 is connected with described rotating shaft 10, and described rotating shaft connecting hole 11 matches with described rotating shaft 10 so that it is can promote slidably reciprocating of described slide block 4 when rotated.
One slide block 4, described slide block 4 includes front limit face 12 and the rear confined planes 13 being parallel to each other, the described front limit face 12 that described slide block 4 is parallel to each other is connected by slide block bottom surface 14 with described rear confined planes 13, described slide block 4 is placed in described housing 1, and between described main lock core and described auxiliary lock core, matching with described housing 1 in described slide block bottom surface 14, matches with described main lock core in described front limit face 12, and described rear confined planes 13 matches with some described auxiliary lock cores.
Below the operation principle of the key expander of the present invention is described in detail.
In the main lockhole 7 that lock core 2 is separately mounted on housing 1 and secondary lockhole 8, slide block 4 is snapped in bottom housing 1 and between slide block limiting plate 9, the bottom surface making slide block 4 contacts with housing 1, front limit face 12 is towards main lockhole 7, rear confined planes 13 is towards secondary lockhole 8, front limit face 12 is connected by slide block bottom surface 14 with rear confined planes 13, slide block limiting plate 9 is by spacing for slide block 4 horizontal plane, it is made to slide on the vertical plane, coordinated with rotating shaft connecting hole 11 by rotating shaft 10, dead bolt 3 is separately mounted on main lock core and auxiliary lock core, finally by the fixing hole 6 in housing 1 peripheral hardware fixed plate 5, whole key expander is fixed on door.
The main dead bolt 3 locked is only when the dead bolt 3 that pair is locked all bounces back, slide block 4 right side could be pushed away, the most only pair is locked a door and all locked when (being equivalent to series connection), key on door then be inserted into dextrorotation on key case and turn 90 degrees (key is fixed on and locks and can not extract), the lock 3 that the master that retracts locks, could be by the key Rotate Left (key can be extracted) of main lock, extract key and remove out the procedure lock of disconnecting switch, while left-handed, slide block 4 right side is pushed away, dead bolt 3 limit near secondary lock, do not allow their key is left-handed to pull key, door also would not be opened, ensure being perfectly safe of operator.In like manner, if needing " control is many ", as long as slide block 4 is lengthened, increase pair and lock.
Compared with prior art, key expander of the present invention uses purely mechanic design, and safety coefficient is high, can meet the chain of many locks simultaneously.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
