Description

Inserting-core lock with anti-lock device

Technical field: the utility model is parts of mortise door lock, belongs to light industry and machinery industry, particularly lockset five metals manufacturing industry.

Background technology: mortise door lock is a kind of door lock that is widely used in the room at present, and its generous, style is easy to use, and anti-theft feature is preferably arranged.But it still has certain weakness, promptly present various inserting-core locks all do not have indoor anti-lock device, though in the room on the door lock, as long as and have the people of this key just can hold key door is opened, thereby enter in the room unblockedly.So just ignored people after work, the custom of staying alone has been arranged, promptly be engaged in reading, think deeply, have a rest, change one's clothes and many-sided requirement such as daily life, and can not limit family member and other people member's invasion.Therefore, mortise door lock still has improved necessity.

Summary of the invention: the purpose of this utility model provides a kind of inserting-core lock with anti-lock device, change the outfit on mortise door lock now, make this mortise door lock have anti-lock device, can be as required, as long as button is pressed, even have original key also can't open door lock, play the purpose that limits others' invasion in all many-sides such as learning, ponder a problem, have a rest or change one's clothes thereby reach the user outdoor.When opening the door,, lock button and just can eject automatically, promptly automatically terminate back locking function, thereby conveniently open the door as long as button is rotated by the direction of unblanking.The utility model is achieved in that promptly and has designed knob hole vertically at former mortise lock body shift fork rear portion that knob hole communicates with former lock head shifting fork breach and be coaxial with lock core hole.Be connected with the rectangular rear end element that an end is a semicircle in knob hole one side, rear end element, shift fork, knob hole and tapered end are linked to be an integral body, and symmetrical with it.Connecting a top in knob hole is ellipsoid, and the bottom is tubular knob, has the counterbore of concentric on the top of knob, and the straight hole littler than counter bore hole diameters arranged at the bottom, has the button pivot slotted eye of a cuboid in knob one side; Like this, the button that in counterbore, connects a bicylindrical bodily form, button is by the cylinder button head on top, I shape button pivot three parts of the cylinder button spindle of bottom and button spindle side are formed, on the circumference of button spindle upper and lower part the button return spring is housed all, the button return spring on top just is assemblied on the step of top counterbore.The button pivot of " worker " font is an important components, and it is installed in the side of button spindle, and upper and lower two partly, there is the key mouth centre, it is given prominence to outside button spindle, and its outer face is and the arc surface of knob hole with circular diameter, thereby knob is smooth in knob hole.When button spindle was pressed, the button pivot can play locking action, gets back to original position and be unlikely, like this, rear end element radially on offer pin hole, place bayonet lock, bayonet lock spring in the hole successively, outermost layer is the sealing of hole lid.When pressing the button bar, the key mouth on the button pivot is just in time aligning bayonet lock, and bayonet lock promptly can not rise the locking of button pivot.When design the utility model, be the locking direction of in time distinguishing button and the orientation that is locked into the position with the key open and close, on the knob outer wall, offer a semicircle counterbore, and on the relevant position of rear end element, offer the positioning bead shell hole, be arranged in order location pellet shot from a slingshot, marble spring in the hole, outermost layer is a sealing bead cover.Can drive shift fork switching lock for eliminating knob, radially dug symmetrical shift fork tongue-and-groove in the knob rear end,, on knob back end circumference face, had cannelure for eliminating the axial landing of the relative tapered end of knob, snap ring is installed in the groove, and the front end face of snap ring is close to the rear end face of knob hole.In the shift fork breach of the tapered end middle section of mortise door lock shift fork is installed, this is the vitals that tapered end opens and closes, and is here further improved.The center of rotation of shift fork is coaxial with lock core and knob, on the circle center line connecting that promptly coexists.The tenon that projection is arranged in the end design of the relative knob of shift fork, this tenon is supporting to be installed in the knob tongue-and-groove, driving shift fork for ease of lock core rotates, and when key is transferred to, knob also can drive shift fork and open and close lock, the key pin hole is dug at the place vertically at the shift fork center of rotation, and a keyway is radially offered in the key pin hole, and key pin connects key pin in the hole.Design has the card key of two projectioies on the key pin outer wall, wherein, rectangular supporting being connected in the shift fork keyway is arranged, and for eliminating the axially displaced or landing of the relative shift fork of key pin, another short card key then is connected between shift fork and the lock core.With respect to an end of lock core two key of symmetry are arranged radially at key pin, in key is inserted into lock core and when putting in place, the key front end just in time is inserted in these two grooves for one section.Play locking action when button is pressed, on key pin, offer the gag lever post hole vertically, connect gag lever post in the hole, be connected with retracting spring on the gag lever post cylindrical.For eliminating the axial landing of the relative key pin of gag lever post, the gag lever post two ends all are designed to the cylinder head greater than the gag lever post hole.When this lock key fully inserted lock core, its front end put in the key on the key pin and can the open and close lock when being pushed into gag lever post near button spindle.The utility model lock structure novelty, assembling is easy, and safe and reliable, cost is low, is easy to be accepted by people.
