Abstract
The handle-door lock device features that a driving semi-gear with through hole in special shape sleeving a squared lever sleeve is laminated on an inclined lifting tongue, tightened by a repositioning spring and meshed with a driven semi-gear. The driven semi-gear is hinged to a shift pawl positined by a torsional spring, and a pushing leaf has shift teeth on one side matching with the shift pawl. The said technology makes the lock be locked out via the handle on the outer side easily without malfunction directly and has the advantages of simple and reasonable structure and convenient operation.
Description
The present invention relates to a kind of handle-door lock locking device.
Known handle-door lock locking device, all comprise frame, substrate, oblique tongue, oblique tongue plectrum, polygonal square bar cover, side's tongue, pushing piece, tapered end and tapered end pusher dog, tiltedly tongue and tiltedly tongue plectrum interlock, tiltedly overlap polygonal square bar cover in the special-shaped through hole in the tongue plectrum, side's tongue and pushing piece Joint, pushing piece is provided with chute and is slidingly matched with the traveller formation that is fixed on the substrate, tapered end pusher dog on the tapered end matches with the inner concave wall of pushing piece one side, this common handle-door lock locking device, when people go out to need counter-locking a door, it is just can the side's of making tongue sealed to insert key turns in keyhole, therefore, say in a sense that its operation is comparatively loaded down with trivial details, if use at night, just more apparent not.
The objective of the invention is to overcome the above-mentioned defective of prior art, thus provide a kind of just can the direct sealed handle-door lock locking device of the side's of making tongue by the outer handle of rotary door.
The present invention includes frame, substrate, oblique tongue, oblique tongue plectrum, polygonal square bar cover, side's tongue, pushing piece, tapered end and tapered end pusher dog, tiltedly tongue and tiltedly tongue plectrum interlock, tiltedly overlap polygonal square bar cover in the special-shaped through hole in the tongue plectrum, side's tongue and pushing piece Joint, pushing piece is provided with chute and is slidingly matched with the traveller formation that is fixed on the substrate, tapered end pusher dog on the tapered end matches with the inner concave wall of pushing piece one side, driving semi-gear dislocation with belt transect abnormity through hole is layered on the oblique tongue plectrum, and strain by back-moving spring, the abnormity through hole overlaps polygonal square bar cover simultaneously, driving semi-gear and the interlock mutually of passive half gear, the hinged pusher dog of one end of passive half gear, pusher dog is located by torsion spring, and another side of pushing piece is provided with moving tooth, and moving tooth matches with pusher dog.
Below in conjunction with drawings and Examples detailed content of the present invention is described
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the present invention does not assemble the structural representation under the oblique tongue plectrum state;
Fig. 3 is that the present invention does not assemble the structural representation under the driving semi-gear state.
As shown in the figure, the present invention includes frame 1, substrate 2, oblique tongue 3, oblique tongue plectrum 4, polygonal square bar cover 5, side's tongue 6, pushing piece 7, tapered end 8 and tapered end pusher dog 9, tiltedly tongue 3 and tiltedly tongue plectrum 4 interlocks, tiltedly the polygonal square bar of cover overlaps 5 in the special-shaped through hole 10 in the tongue plectrum 4, side's tongue 6 and pushing piece 7 Joints, pushing piece 7 is provided with chute 11 and is slidingly matched with traveller 12 formation that are fixed on the substrate 2, tapered end pusher dog 9 on the tapered end 8 matches with the inner concave wall 13 of pushing piece 7 one sides, driving semi-gear 15 dislocation with belt transect abnormity through hole 14 are layered on the oblique tongue plectrum 4, and by back-moving spring 16 tensions, abnormity through hole 14 overlaps polygonal square bar cover 5 simultaneously, driving semi-gear 15 and passive half gear 17 interlock mutually, the hinged pusher dog 18 of one end of passive half gear 17, pusher dog 18 is by torsion spring 19 location, another side of pushing piece 7 is provided with moving tooth 20, and moving tooth 20 matches with pusher dog 18.Under user mode, clockwise rotate handle, square bar drives polygonal square bar cover 5 and tiltedly tongue plectrum 4 rotations, and oblique tongue 3 is opened.And when rotating counterclockwise handle, polygonal square bar cover 5 drive driving semi-gear 15 and with driving semi-gear 15 passive half gear 17 rotations of interlock mutually, the pusher dog 18 on passive half gear 17 is stirred the moving tooth 20 on pushing piece 7 one sides, the side's of making tongue 6 skids off sealed.When unblanking, the tapered end pusher dog 9 on the tapered end 8 clockwise rotates, and matches with the inner concave wall 13 of pushing piece 7 one sides, and the side's of making tongue 6 slides in the other direction, and lock is unlocked.
The present invention is by above-mentioned specific design, has simple and reasonablely, and locking is convenient to operation, The advantage that reliability is strong is a kind of desirable handle door lock locking device.
