Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Such as Fig. 1 and in conjunction with shown in Fig. 2 to Fig. 8, one is anti-cracks safety door latch, including lock core parts 1 and key member 2, described key member 1 includes the shank of the key 3 and key bar 5, one end of described the shank of the key 3 is provided with T-shaped groove 15, and one end of described key bar 5 is provided with connection projection 16 corresponding with groove 15；Described lock core parts 2 include lock core shell 7 and lock core cylinder 9, it is provided with lock core sleeve 8 in described lock core shell 7 top, described lock core cylinder 9 is sleeved in lock core sleeve 8, the second lock core groove 10 it is provided with on the left of described lock core cylinder 8, described lock core shell 7 inside left part is provided with the first lock core groove 22, the position with the second lock core groove 10 of described first lock core groove 22 is corresponding, it is provided with spring cup 11 bottom described first lock core groove 22, described spring cup 11 top is provided with lock core spring 12, described lock core spring 12 top is provided with spring base 13, described spring base 13 top is provided with disconnected key door 19, described disconnected key door 19 top is provided with disconnected key door jacking block 14.
In the present embodiment, being provided with slotted eye 20 on the left of described groove 15, be provided with key spring 4 in described slotted eye 20, described key spring 4 is connected to frustrates a slide bar 6, and described key bar 5 wherein end face is provided with the first chute 17 of connection corresponding with frustrating a slide bar 6.Disconnected key door 19 can connection corresponding with projection 16, described disconnected key door jacking block 14 is identical with projection 16 structure and can corresponding with groove 15 be connected.
The a slide bar 6 right-hand member top of frustrating of the present embodiment is provided with projection 18, the second chute of connection corresponding with projection 18 it is provided with on the left of described disconnected key door jacking block 14, being provided with the keyhole 21 of connection corresponding with key bar 5 in described lock core cylinder 9, described key bar 5 right part forms angular cut.
It is noted that the lock core spring 12 of the present embodiment includes the first spring and the second spring, described first spring and the second spring are arranged in the first lock core groove 22 parallel, and the elastic effect of dual spring is better, durable.Described disconnected key door 19 is provided with T-shaped shrinkage pool and matches with the linking of key bar 5 projection 16 shape.
Additionally, described disconnected key door jacking block 14 is arranged on the second lock core groove 22 top and is fixed in lock core cylinder 9, and the groove 15 T-shaped with on the shank of the key 3 is corresponding.
The shank of the key 3 is connected with projection 16 by groove 15 with key bar 5 and prevents activity all around, the shank of the key 3 and key bar 5 prevent up and down by frustrating a slide bar 6, when key bar 5 inserts lock core cylinder 9, lock core cylinder 9 backs down, and frustrates a slide bar 6 and can prevent key bar 5 and the shank of the key 3 can be up and down.Under the active force of lock core spring 12, disconnected 19 the shank of the keys 3 of key door up push up and realize key bar 5 and the shank of the key 3 is frustrated disconnected.The shank of the key 3 enters on the way the T word screens of lock core parts 2 (lock core parts are fixed on lock core), it is impossible to transfer to.Lock core parts 2 coordinate with the male and female of disconnected key door 19, make the link position of key bar 5 and the shank of the key 3 reach seamless.
Also not inserting at key bar 5, when key bar 5 is left out doing hoodle or blade construction, lock core parts 2 are to rotate.When any key or anything inject in lock core, and can not correctly coordinate the conjunction position of cutting of disconnected key door 19 and lock core parts 2 to frustrate position when cutting off or can not cut off, disconnected key door 14 can coordinate the spacing stuck fast lock core of lock core shell 7 so that it is can not.After correct key inserts disconnected key door can utilize the power of spring the shank of the key is up pushed into lock core parts cut conjunction face.Now the shank of the key 3 has been enter into the button bit of lock core parts and can not pull out outward.Disconnected key door 19 is also replied and is closed door state, no longer has screens with lock core shell 7.
When the shank of the key 3 band movable lock core cylinder 9 rotates slight angle, the inner circle of lock core shell 7 can withstand disconnected key door 19, makes the shank of the key 3 can only have spinning movement.When dialling key, as long as the shank of the key 3 is turned round to the horizontal level that resets, then down press, be depressed into and dial afterwards in line with key bar 5.
Based on above-mentioned, the present invention adopts and frustrates position and cut to close and do not stay the disconnected key cylinder structure of keyhole, and when not having keyhole, lock core can rotate, when the key not matched inserts, under the effect of disconnected key door 19, lock core is locked, it is impossible to open；When additionally key bar and the shank of the key are frustrated disconnected, the shank of the key can not be extracted, and both must reset after in line and can transfer to, it is prevented that key bar 5 is left permanently in lock core, and simple in construction is safe and reliable, has very strong practicality simultaneously.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should in the protection domain being defined in the patent claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
