First latch hook 2 and second latch hook, 3 its surfaces are flat board, and no groove relates to, for ease of installing; the outer end of two latch hooks all is a warp architecture; can conveniently hang on this handle like this, and externally part coats buffering plastic cement 5, can play the effect that buffering and protection latch hook are not corroded.

Embodiment one

Lock housing 1 is taken away, can be seen cut-away view as shown in Figure 3, by shown in Figure 3, locking device further comprises: the steel ball 8 and the connecting rod 10 that embed on brake block 7, steel ball frame 9, the steel ball frame 9.

Brake block 7 is the U-lag assembling structure, brake(-holder) block 72 by two symmetries is formed, and outside inboard with lock housing 1 is fixed, and its inside bottom size is less than its inboard opening size, first latch hook 2 passes between two brake(-holder) blocks 72 of brake block 7, and stretches out at brake block 2 opening parts.

Please refer to Fig. 4, it is the schematic diagram of brake(-holder) block 72, as seen from the figure, brake(-holder) block 72 outward flanges are L shaped, inward flange comprises the latch hook spigot surface 724 vertical with the base, with the braking surface 722 of the vertical adjustment face 723 of this latch hook spigot surface 724, the inclination that is connected with this adjustment face 723 other ends, and be connected with these braking surface 722 other ends be used for preventing the falling stop face 721 that steel ball falls.Wherein, the height of adjustment face 723 can design according to the size of steel ball 8.

Steel ball frame 9 is arranged on the opening of brake block 7, form by two intermediate plates, be divided into upper clip 91 and lower clamping piece 92, upper and lower two intermediate plates lay respectively at the both sides up and down of first latch hook 2, first latch hook 2 can slide between upper clip 91 and lower clamping piece 92, and upper and lower two intermediate plates respectively are connected to switching device by a connecting rod 10.

Please refer to Fig. 5 A and Fig. 5 B, be respectively the schematic diagram of upper clip 91 and lower clamping piece 92, and, respectively be provided with several steel ball holes 93 on upper clip 91 and the lower clamping piece 92, steel ball hole 93 respectively is provided with a steel ball 8, and described first latch hook slides between two intermediate plates, each intermediate plate respectively is connected with described switching device by a connecting

rod

10,93 cross sections, steel ball hole are trapezoidal, and the size of upper and lower opening is inconsistent, can guarantee that like this steel ball 8 can not drop in steel ball hole 93.

Please return with reference to figure 3 and simultaneously with reference to figure 6, switching device comprises that tapered end 6, contiguous block 13, slide block 11, stage clip 12, slide block 11 are connected with the intermediate plate of locking device by connecting rod 10.

Tapered end 6 is built-in with lock core 4 and rotating cam under lock core control;

Contiguous block 13 is L shaped, and it is arranged on outside the tapered end 6, and a side is also fixedlyed connected with second latch hook 3, play the effect of bracing frame, and second latch hook 3 can be made into integration with contiguous block 13.

Slide block 11 also is L shaped, it comprises dual-side, dual-side is rectangular, one side of first side 111 is fixedlyed connected with connecting rod 10, opposite side is fixing with tapered end 6 by a stage clip 12, second side 112 is provided with a perforate 113, and the cam of tapered end 6 and lock core 4 interlocks is embedded in the perforate 113, and can drive slide block 11 and slide in contiguous block 13.

Below please refer to Fig. 7 and Fig. 8, the course of work of the present utility model is described.

Please refer to Fig. 7, when door and window does not need to lock, first latch hook 2 can be free to slide in lock housing 1, at this moment, the cam that lock core 4 drives drives slide block 11 simultaneously and slides towards second latch hook, 3 one sides in a side of second latch hook 3, compression press spring 12, and drivening rod 10, thereby mobile steel ball frame 9 turns right mobilely, steel ball 8 is not fitted with the braking surface 722 of brake block 7.

Please refer to Fig. 8, when needs lock door and window, adjust the degree of depth that first latch hook 2 inserts lock housing 1, rotational lock core 4 afterwards, make cam direction towards first latch hook 2 in perforate 113 rotate, and drive slide block 11 and slide towards a left side, stage clip 12 ejects slide block 11, with steel ball frame 9 basal sliding towards brake block 7 in the opening of brake block 7, steel ball 8 is braked the braking surface 722 of piece 7 and pushes down slide block 11 by connecting rod 11, can realize locking.

When needs unlock, only need rotational lock core 4, cam driven slide block 11 rotates towards the right side, and stage clip is compressed, and steel ball frame 9 breaks away from brake block 7, can unlock.

Embodiment two

Please refer to Fig. 9, it is the structural representation of embodiment for second of a kind of dull and stereotyped locking device of the utility model, be that with the difference of embodiment one brake block 7 only comprises a brake(-holder) block 72 and square guide pad 71, the first latch hooks 2 are arranged between brake(-holder) block 72 and the square guide pad 71.
