Abstract
The utility model relates to an interlocking safety switching mechanism for an anti-theft door. The switching mechanism comprises a lock core; a pinion wheel linked with the lock core shaft of the lock core is fixed on the lock core shaft; the pinion wheel is meshed with a pinion rack; a manually-operated sheath is sleeved outside the lock core; a gearwheel linked with the manually-operated sheath is fixed thereon; a gearwheel is meshed with a large gear rack; a manually-operated hand wheel is fixed outside the manually-operated sheath; a key insertion hole opposite to the lock core shaft is formed in the middle of the manually-operated hand wheel; and interlocking mechanisms controlled by the large gear rack and the pinion rack respectively are in interlocking fit with a safe mechanism. The utility model overcomes the defects of complicated structure and lower reliability of the common interlocking safety switching mechanism for an anti-theft door in the prior art. By adopting the design that the linked interlocking structure, the large gear rack and the pinion rack are all integrated into a lock body, the product structure is simplified, the anti-theft performance is improved, and the advantages of compact structure, flexible open and close, and high reliability are achieved.
Description
Technical field
The utility model relates to a kind of security door interlocking insurance switching mechanism.
Background technology
Traditional security door all is on the door body door lock to be set, and being matched by the lockhole of diverse location on the dead bolt of door lock control and locking bar and the doorframe closes locking action.This known latch-up structure, its theftproof performance is imperfection also, the lawless person can also unblank by some technical or destructive means, particularly the switching manipulation of its interlocking mechanism and insurance institution splits the diverse location at the door body, therefore its structure is not only complicated, and has reduced the reliability that product uses.
Summary of the invention
In order to overcome the complex structure of common security door interlocking insurance switching mechanism in the prior art, and the also lower problem of reliability, the utility model provides a kind of security door interlocking insurance switching mechanism, this security door interlocking insurance switching mechanism simple and compact for structure, open and close flexibly, theftproof performance is strong, reliability is high.
The technical scheme that its technical problem that solves the utility model adopts is: comprise lock core, the pinion of fixing and lock core shaft's interlock in the lock core shaft of lock core, the pinion pinion rack, lock core sleeve manually overlaps, manually put gear wheel fixing and its interlock, gear wheel meshes big tooth bar.
Manually the manual handwheel of cover external fixation manually is provided with the key hole relative with lock core shaft in the middle part of the handwheel.
Interlocking mechanism and insurance institution's reciprocal interlocking that big tooth bar and pinion rack are controlled respectively cooperate.
The utility model is by above-mentioned specific design, and the large and small tooth bar of integrated interlock interlocking, insurance institution has been simplified product structure greatly on a lock body, has improved theftproof performance, the advantage that have compact conformation, open and close flexibly, reliability is high.
Description of drawings
Below in conjunction with drawings and Examples the detailed content that this is real is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 1.
The specific embodiment
As shown in the figure, the utility model comprises lock core 1, in the lock core shaft 2 of lock core 1, fix pinion 3 with lock core shaft's 2 interlocks, pinion 3 engagement pinion racks 4, lock core 1 overcoat is cover 5 manually, manually fix gear wheel 6 on the cover 5 with its interlock, the big tooth bar 7 of gear wheel 6 engagements, manually overlap the manual handwheel 8 of 5 external fixation, manually handwheel 8 middle parts are provided with the key hole 9 relative with lock core shaft 2, interlocking mechanism and insurance institution's reciprocal interlocking that big tooth bar 7 and pinion rack 4 are controlled respectively cooperate, and promptly big tooth bar 7 links to each other with interlocking mechanism, and pinion rack 4 links to each other with insurance institution.In working order down, rotation manual handwheel 8 rotates manual cover 5 and gear wheel 6 simultaneously, gear wheel 6 drives big tooth bar 7 and moves up and down, interlocking mechanism and doorframe locking, when inserting key rotation lock core 1, lock core shaft 2 drives pinion 3 and rotates simultaneously, and pinion 3 drives pinion rack 4 and moves up and down, and makes the horizontal door bolt of locking interlocking mechanism of insurance institution.Above-described embodiment only is that the preferred implementation to the utility model security door interlocking insurance switching mechanism is described; be not that design and scope to utility model limits; under the prerequisite that does not break away from the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model all should fall into the protection domain that the utility model security door interlocking insures switching mechanism.
