Further, sliding lock core top is the driving cog ratcheting with synchronous gear, and middle part is to be set on limit guide post Limit sliding chutes, lower part are drive rod card slot, cooperate with the sliding slot position on lock frame and slide.

Further, handle can be overturn in its hinged end by elastic component.

Further, the non-articulated end of handle is equipped with longitudinal elasticity by compression leg and lateral spacing card.

Further, fastener is hinged in flexible fastening mouth for fixing spacing card, the non-articulated end of fastener is set Flexible rebound part and elasticity are by compression leg cooperation solution Handle for lock.

Further, lock frame end is additionally provided with fixing piece.

In conclusion the utility model has following advantages:

The utility model handle is hidden, and is slided by rotation handle band movable lock core sliding block, so that drive rod carries out screen window It is highly-safe built in locking and unlatching, entire locking and closing course, and integrally use embedded hiding lock body, appearance Beautiful convenient transportation.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and embodiments:

Embodiment 1:

A kind of theftproof lock, as shown in Figure 1-3, include locking frame 1 and being hinged on the lock positive handle 2 of frame 1, with further reference to attached Fig. 1, handle 2 are connected with synchronous gear 3 in the raised platforms 11 at lock 1 back side of frame, and lock 1 back side of frame passes through limit guide post 4 and sliding It is connected in the middle part of lock core 5, sliding 5 top of lock core is connect with synchronous gear 3, and lower part is for connecting drive rod.

Specifically, sliding 5 top of lock core is the driving cog 51 ratcheting with synchronous gear 3, middle part is to be set on limit guide post 4 Limit sliding chutes 52, lower part be drive rod card slot 53, with lock frame 1 on sliding slot position 12 cooperate slide.

When synchronous gear 3 rotates counterclockwise, driving cog 51 is moved up, i.e., sliding lock core 5 is whole moves up along limit guide post 4, To which drive rod card slot 53 moves up, the drive rod being arranged in drive rod card slot 53 is driven to move up, achievees the purpose that control screen window.

When synchronous gear 3 rotates clockwise, mechanism and mechanism is rotated counterclockwise similarly, do not repeat herein.

With continued reference to attached drawing 2 and 3, the non-articulated end of handle 2 is also connect with the flexible fastening mouth 6 on the lock frame 1, specifically , the non-articulated end of handle 2 is equipped with longitudinal elasticity by compression leg 21 and lateral spacing card 22, and corresponding, elasticity is solid Determine to be hinged with fastener 61 in mouth 6 for fixing spacing card 22, the non-articulated end of fastener 61 is equipped with elastic recoil part 62.

Elastic recoil part 62 and elasticity are by the cooperation unlock of compression leg 21 handle 2, when elasticity is pushed by compression leg 21, engaging Part 61 is rotated along its hinged end, so fastener is separated with limit detent, is unclamped elasticity and is pressed compression leg 21, handle integrally flicks, tool Elastic component of the body by handle in its hinged end is overturn.

For the connection for realizing itself and screen window forms, locks 1 end of frame and be additionally provided with fixing piece 7, connect it with profile, realize lock The whole assembly of body.

Above embodiment is only to illustrate the technical ideas and features of the present invention, and its object is to allow be familiar with this skill The people of art can understand the content of the utility model and implement accordingly, not limit the protection scope of the present invention. It is all according to the spirit of the present invention substantially equivalent transformation that is done or modification, should all cover the protection scope of the utility model it It is interior.
