Description
The utility model discloses a kind of wing that is used for, particularly be applicable to the lock that uses on door or the window.
Existing safety lock, generally form by lock body, lock core, dead bolt and manual bolt, when closing, wing is run into the oblique tongue of doorframe and door leaf can be pinned, the insurance dead bolt is stirred the reversed column that is fixed on the key plectrum by key again and is stretched out, and realizes the dual fail-safe of door leaf lock, if the people has forgotten with insuring dead bolt on the key, depend merely on the skew bolt lock door, then tiltedly tongue is stirred by foreign matter easily and is made a unlatching.
The purpose of this utility model be to overcome existing lockset insurance dead bolt can not and close door leaf in and the defective of stretching out and a kind of automatic safety lock of designing.
The purpose of this utility model realizes by following measure: it is made up of lock body, oblique tongue, insurance dead bolt, lock core, key plectrum, spring and manual bolt, tiltedly be provided with a linkage between tongue 2 and the insurance dead bolt 3 and 4, this device is by the insurance dead bolt location-plate 6 of " " shape, tiltedly tongue location-plate 12 and pulley 13 are formed, one side of " " shape location-plate 6 connects with dead bolt 3 and dead bolt 4 by pin 5, one end links with the reversed column that is fixed on the key plectrum, has a lonely groove of circle on the lower end surface of location-plate 6; One end of location-plate 12 links to each other with oblique tongue 2, the other end and lock body 1 between a spring 11 is installed, on the upper end of location-plate 12, have one with the lonely groove of location-plate 6 isodiametric circles; Pulley 13, is installed between location-plate 6 and the location-plate 12 by turning cylinder 14 and 16 by the connection bent plate 15 of " " shape.
The utility model has the advantages that: do not need by key, by the linkage between insurance dead bolt and the oblique tongue, can realize insuring dead bolt and stretch out automatically and enter lockhole, avoid having forgotten that because of the people stirring the insurance dead bolt with key makes the single oblique tongue of insurance be stirred the situation that makes a unlatching by foreign matter easily to take place.
Accompanying drawing 1 is a structural representation of the present utility model:
Among the figure: 1--lock body, the oblique tongue of 2--, 3,4--insures dead bolt, 5--pin, 6--location-plate, the manual bolt of 7--, 8--baffle plate, 9--spring, 10--handle, 11--spring, the 12--location-plate, the 13--pulley, 14, the 16--turning cylinder, 15--" " shape connects bent plate, 17--key plectrum.
Below in conjunction with accompanying drawing the utility model is further described:
When door leaf did not close, tiltedly tongue 2 was in the state that stretches out by 11 effects of the spring between location-plate 12 and the other end and the lock body 1, and this moment, pulley 13 entered in the circular lonely groove of location-plate 6 lower end surface, made dead bolt 3 and 4 indentation lock bodies 1, was in non-insured state; When need are closed door leaf, the lockhole that assembles on the wing collision doorframe, make oblique tongue 2 retraction lock bodies, when the circular lonely groove on circular lonely groove on the cross section, location-plate 12 top and location-plate 6 lower end surface is symmetrical, pulley 13 enters in the circular lonely groove on the location-plate 12, and insurance dead bolt 3 and 4 is by the spring of installing on connected manual bolt 9 and the manual bolt, make insurance dead bolt 3 and 4 stretch out lock body 1 and enter in the lockhole, realize the insurance function of lock; When needs are opened door leaf, stir the plectrum 17 that is fixed on the key plectrum with key, driving dead bolt 3 and 4 by location-plate 6 shrinks in lock body gradually, when the circular lonely groove on circular lonely groove on location-plate 6 lower end surface and the cross section, location-plate 12 top is symmetrical, tiltedly tongue 2 stretches out lock body by the spring 11 between location-plate and one end and the lock body 1, pulley 13 can enter in the circular lonely groove of lower section of location-plate 6, and door leaf promptly is unlocked.
