Now along with progress of science and technology, the door-window lockset of various set high-tech technology also emerges in an endless stream, as the induction type door lock, electronic password lock etc., though its safety is greatly improved, because complex structure, cost is higher, be used in places such as high-grade security door, safety cabinet, that uses on common door and window is less more.
The utility model content
The utility model provides a kind of simple in structure at deficiency of the prior art, makes the low door-window lockset of adult, and this door-window lockset needs private key just can open, and can effectively prevent to bump the generation that handle is opened lockset situation because of false touch.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of door-window lockset, comprise base, be articulated with handle on the described base, this handle is provided with cavity, the diapire of this cavity has first through hole, and the left side of described cavity processes first step from top to down respectively, second step, be equipped with lock core in the cavity, described lock core has and is used for second through hole that key stretches into, and has third through-hole on this lock core sidewall, the inner surface of described lock core also processes the 3rd step, the lower end of lock core is provided with the screens pin, the screens pin stretches out from first through hole, also be provided with elastic reset spare between the lower surface of described lock core and the cavity diapire, side corresponding to the screens pin on the described base is provided with first block, handle is provided with second block corresponding to the side of first block, described lock core is placed with a limited block corresponding to the third through-hole place, the top of this limited block is provided with one first pushing block, a side opposite with third through-hole on the described limited block is provided with groove, in this groove elastic parts is set, an end of described elastic parts pushes up mutually with limited block, and the other end pushes up mutually with the inner surface of lock core.
In the technique scheme, described elastic parts is a stage clip.
In the technique scheme, described elastic reset spare is a volute spring.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
The utility model is simple in structure, and it is low to make adult, and needs private key just can open, and can effectively prevent to bump the generation that handle is opened situation with lockset because of false touch, has improved safety greatly.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
See Fig. 1～Fig. 6, door-window lockset comprises base 1, is articulated with handle 3 on the described base 1, this handle 3 is provided with cavity 30, the diapire of this cavity 30 has first through hole 38, and the left side of described cavity 30 processes first step 32, second step 34 from top to down respectively.
Be equipped with lock core 3 in the described cavity 30, described lock core 3 has and is used for second through hole 50 that key 13 stretches into, and has third through-hole 56 on these lock core 3 sidewalls, the inner surface of described lock core 3 also processes the 3rd step 54, the lower end of lock core 3 is provided with screens pin 52, screens pin 52 stretches out from first through hole 38, also is provided with elastic reset spare 11 between the lower surface of described lock core 3 and cavity 30 diapires.Preferably, described elastic reset spare 11 is a volute spring.Like this when lock core 3 when pressing down, elastic reset spare 11 can be depressed into very thin, thereby make things convenient for the installation of elastic reset spare 11.
Side corresponding to screens pin 52 on the described base 1 is provided with first block 12, handle 3 is provided with second block 36 corresponding to the side of first block 12, described lock core 3 is placed with a limited block 7 corresponding to third through-hole 56 places, the top of this limited block 7 is provided with one first pushing block 72, a side opposite with third through-hole 56 on the described limited block 7 is provided with groove 70, in this groove 70 elastic parts 9 is set, one end of described elastic parts 9 pushes up mutually with limited block 7, and the other end pushes up mutually with the inner surface of lock core 3.Preferably, described elastic parts 9 is a stage clip.The employing stage clip is easy to process, and manufacturing cost is lower.
Fig. 7 is the structural representation of key, and key 13 comprises one columniform spoon of bar 130, and the side of described spoon bar 130 lower ends is provided with one second pushing block 132.
Operating principle, when down pushing lock core 3, the 3rd step 54 that is provided with on the lock core 3 leans the upper surface of first pushing block 72, thereby first pushing block 72 is moved down, the limited block 7 that links together with first pushing block 72 also and then moves down, when limited block 7 moves to second step 34 places, limited block 7 is under the effect of elastic parts 9, slide onto second step 34 from third through-hole 56, limited block 7 also is that limited block 7 can not be gone up when locked, move down, at this moment, be arranged on the screens pin 52 of lock core 3 lower ends and the both sides that second block 36 just lays respectively at first block 12, base 1 rotation relatively of handle 3 this moment.
When needs are unblanked, key 13 is inserted from second through hole 50, and key 13, this moment, first pushing block 72 was pushed to the right side under the effect of second pushing block 132, that is to say, make limited block 7 leave second step 34, limited block 7 just moves up under the effect of elastic reset spare 11 like this, and finally leans on first step 32, at this moment, screens pin 52 breaks away from second block 36, and promptly rotatable handles 3, make its rotation.
