Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but this utility model is permissible The multitude of different ways being defined by the claims and covering is implemented.

Such as Fig. 1 and combine shown in Fig. 2 to Fig. 8, a kind of anti-cracks safety door latch, including lock core parts 1 and key Parts 2, described key member 1 includes that the shank of the key 3 and key bar 5, one end of described the shank of the key 3 are provided with T The groove 15 of font, one end of described key bar 5 is provided with connection projection 16 corresponding with groove 15；Described lock Core components 2 includes lock core shell 7 and lock core cylinder 9, is provided with lock core sleeve 8, institute in described lock core shell 7 top State lock core cylinder 9 to be sleeved in lock core sleeve 8, on the left of described lock core cylinder 8, be provided with the second lock core groove 10, Described lock core shell 7 inside left part is provided with the first lock core groove 22, locking with second of described first lock core groove 22 The position of core groove 10 is corresponding, is provided with spring cup 11, described spring cup 11 bottom described first lock core groove 22 Top is provided with lock core spring 12, and described lock core spring 12 top is provided with spring base 13, described spring base 13 Top is provided with disconnected key door 19, and described disconnected key door 19 top is provided with disconnected key door jacking block 14.

Further, it is provided with slotted eye 20 on the left of described groove 15, in described slotted eye 20, is provided with key spring 4, Described key spring 4 connects frustrates a slide bar 6, and described key bar 5 wherein end face is provided with and frustrates a slide bar 6 First chute 17 of corresponding connection.

Further, described disconnected key door 19 can connection corresponding with projection 16, described disconnected key door jacking block 14 Identical with projection 16 structure and can corresponding with groove 15 be connected.

Further, frustrate a slide bar 6 right-hand member top described in and be provided with projection 18, described disconnected key door jacking block 14 left side Side is provided with the second chute of connection corresponding with projection 18.

Further, the keyhole 21 of connection corresponding with key bar 5, institute it are provided with in described lock core cylinder 9 State key bar 5 right part and form angular cut.

Further, described lock core spring 12 includes the first spring and the second spring, described first spring and second Spring is arranged in the first lock core groove 22 parallel, and the elastic effect of dual spring is preferable, durable.

Further, described disconnected key door 19 is provided with T-shaped shrinkage pool and is connected phase with key bar 5 projection 16 shape Coordinate.

Further, described disconnected key door jacking block 14 is arranged on the second lock core groove 22 top and is fixed on lock core cylinder Grooves 15 in 9 and 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 Prevent up and down with key bar 5 by frustrating a slide bar 6, when key bar 5 inserts lock core cylinder 9, lock core cylinder 9 back down, and frustrate a slide bar 6 and can prevent the key bar 5 can be up and down with the shank of the key 3.Effect at lock core spring 12 Under power, disconnected 19 the shank of the keys 3 of key door up push up and realize key bar 5 and frustrate disconnected with the shank of the key 3.The shank of the key 3 is on the way Enter into 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 with The male and female of disconnected key door 19 coordinates, and makes key bar 5 reach seamless with the link position of the shank of the key 3.

Also do not insert at key bar 5, when key bar 5 does not considers to do hoodle or blade construction, lock core parts 2 It is to rotate.When any key or anything inject in lock core, and can not correctly coordinate disconnected key door 19 with lock core parts 2 cut conjunction position frustrate position cut off or can not cut off time, disconnected key door 14 can coordinate lock core The spacing stuck fast lock core of shell 7 so that it is can not.After correct key inserts, disconnected key door can utilize bullet 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 lock core parts Button bit 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 position that resets Put, the most down press, be depressed into and dial the most afterwards with key bar 5.

This utility model uses frustrates position and cuts to close and do not stay the disconnected key cylinder structure of keyhole, is not having keyhole In the case of lock core can rotate, when the key that do not matches inserts, by lock core under the effect of disconnected key door 19 Locked, it is impossible to open；When additionally key bar is frustrated disconnected with the shank of the key, the shank of the key can not be extracted, and both must answer Position in line after can transfer to.Key bar 5 is prevented to be left permanently in lock core, simple in construction, safe and reliable, Has the strongest practicality simultaneously.

Preferred embodiment of the present utility model described in detail above.Should be appreciated that the common of this area Technical staff just can make many modifications and variations according to design of the present utility model without creative work. Therefore, all technical staff in the art pass through on the basis of existing technology according to design of the present utility model The available technical scheme of logical analysis, reasoning, or a limited experiment, all should be by claims institute In the protection domain determined.
