Abstract
The utility model relates to an emergency door lock, comprising an inner handle, an outer handle, an outer tube, an assistant tube set and a linkage mechanism, characterized in that: a lock bell is arranged in the outer handle, a transmission plate is arranged in the outer tube, one end of the transmission plate is fixedly connected with the lock bell, another end of the transmission plate drives the assistant tube set rotate by a connection piece in the assistant tube set. A groove is arranged on the connection piece and one end of the transmission plate is inserted into the groove. The groove uses a '-' shape or cross shape. When the inner handle locks the door, it is only necessary to open the door only by a hand or some articles capable of rotating the lock bell, thus the lock bell and the transmission plate replace the function of the lock core and omits the dependence on the designed key, thus the emergency door lock is conveniently used in the house or some not very important places.
Description
Technical field
The utility model belongs to a kind of door knob lock, is specifically related to be used for the escape door of indoor use lock.
Background technology
Similar on the door knob lock construction that generally uses on the market at present, such as the disclosed a kind of structure improved practical door lock of utility model patent (CN200820162164.4), comprise inside and outside handle, lock core, dead bolt and link gear, outer handle links to each other with link gear by outer tube, and link gear is stirred dead bolt, after key inserts lock core, turn the handle, and drive dead bolt by link gear, and making dead bolt retraction lock body, door is opened the most at last.At present indoor also is a large amount of this door locks of use, because after door lock is lived, generally can only rotate Internal handle from the inside just can open the door, the people of outside will have key to open, but in case there is emergency to take place, for example the people of the inside, washroom emergency situations occurs and can not open the door from the inside, and Wai Mian people also needs to find key to open the door and rescues the people so, therefore after guaranteeing certain safety, having a kind of can be necessary from the door knob lock that can open outdoors in case of emergency.
Summary of the invention
Technical problem to be solved in the utility model is: on the technical foundation of existing door knob lock, provide a kind of convenience not need escape door that key can unblank lock in indoor use.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of escape door is lock, comprise inside and outside handle, outer tube, looped pipeline group and link gear, it is characterized in that: be provided with the lock bell in the described outer handle, be provided with driver plate in the described outer tube, driver plate one end is fixedlyed connected with the lock bell, and the driver plate other end drives the rotation of looped pipeline group by the connector that is located in the looped pipeline group.
Described connector is provided with groove, and driver plate one end inserts in the groove.
Described groove can adopt in-line or cross.
Be inserted in a transmission location-plate that is used to limit the driver plate axially-movable on the described driver plate, the transmission location-plate offsets with the elastic collet that is located in the outer tube.
Have a holddown groove that is used to insert driver plate on the described lock bell.
Adopt said structure, under the situation that Internal handle is lived door lock, only need to rely on hand or object that more at will can the rotation lock bell door of can unblanking to open, here locking bell and driver plate has then replaced the function of lock core and has saved the key of necessary dependence appointment, convenient is not that providing convenience property is used in very important place in indoor or some safeties.
Description of drawings
Fig. 1 is an explosive view of the present utility model;
Fig. 2 is the sectional drawing of the utility model front view.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model is the improvement to existing door knob lock, it is combined successively by outer handle 1, outer tube 2, looped pipeline group 3, cover dish group 12, link gear 4, button spindle 13, interior pipe 14, interior button 15, body case group 16, interior cover dish 17, cover dish 18, Internal handle 19, link gear 4 comprises drive sleeve group 20, spring 21,90 degree latch plates 22, driver 23 and interior driver plate 24, in outer tube 2, be provided with elastic collet 10, be used for outer tube 2 and be connected with the removable of outer handle 1, link gear 4 is stirred the dead bolt (not shown).
The utility model improvements are: be provided with lock bell 5 in the outer handle 1, be provided with driver plate 6 in the outer tube 2, driver plate 6 one ends are fixedlyed connected with lock bell 5, driver plate 6 other ends drive 3 rotations of looped pipeline group by the connector 7 that is located in the looped pipeline group 3, the end that driver plate 5 is connected with looped pipeline group 3 is slightly less than the other end, be inserted in a transmission location-plate that is used to limit the driver plate axially-movable on the driver plate, elastic collet 10 in transmission location-plate 9 and the outer tube 2 offsets, make driver plate 6 under the effect of transmission location-plate 9, can not move axially, connector 7 is provided with groove 8, driver plate 6 one ends insert in the groove 8, groove 8 can be in-line or cross, have a holddown groove 11 that is used to insert driver plate 6 on the lock bell 5, the outboard end of lock bell 5 can adopt the shape with the keyhole of common lock core, can guarantee attractive in appearance like this, simultaneously under the situation that door lock is lived, as long as look for the object that can block firm keyhole arbitrarily, such as coin, board etc., just the rotatable lock bell is unblanked, the outboard end of lock bell also can adopt the mode of knob, and the direct rotation lock bell 5 of convenient finger is unblanked.
Rotation lock bell 5 just can drive driver plate 6 and rotate, driving looped pipeline group 3 then rotates, reached with key and inserted the identical effect of lock core rotation, looped pipeline group 3 drives link gear 4 and stirs dead bolt, open door lock, adopt said structure, under the situation that Internal handle is lived door lock, only need to rely on hand or object that more at will can the rotation lock bell door of can unblanking to open, here locking 6 of bell 5 and driver plates has replaced the function of lock core and has saved the key of necessary dependence appointment, convenient is not that use in very important place in indoor or some safeties, for example, washroom etc., providing convenience property.
