Abstract
The utility model relates to an inner door lock. A lock tongue plate and a shifting wheel of the existing inner door lock are generally connected through gears when the tongue is locked under external force, the gears can be rotated to open the inner door without ideal anti-prizing effect. The utility model comprises a lock casing, a face plate, a lock tongue with blind holes, a lock tongue with through holes, an inclined movable tongue, etc. The utility model is characterized in that the lock tongue plate is connected with the shifting wheel through a connecting rod which can connect the lock tongue plate and the shifting wheel; when the inner door lock is tightly locked, the connecting rod is vertical to the lock tongue plate; the connecting point of the connecting rod on the lock tongue plate and the shifting wheel is arranged at a straight line with the center of a handle knob to form a stopping point; when the tongue is locked under the external force, the connecting rod can not rotate. The inner door lock has the advantage of good anti-prizing effect.
Description
The utility model relates to a kind of Inner door lock, especially a kind of Inner door lock that has linkage component.
Security door in the market has a kind of ventilative daylighting type that is, promptly establish the inside door that can only open to indoor direction in addition in the door leaf inboard of security door, and the security door door leaf of corresponding inside door adopts the metal lattice.Now employed to fasten device a kind of be to adopt latch to inside door, and a kind of is to adopt Inner door lock.Because the insufficient strength of metal lattice itself, the antitheft effect of security door door leaf more is embodied on the anti-theft effect of inside door, as adopt latch, insufficient strength then, easily rushed open under external force, therefore people adopt Inner door lock more, this is that a kind of user need only can open and lock by turning handle indoor, and must not use the lockset of key, but the gear interlock is generally used in pulling out of present Inner door lock between wheel and the bolt plate, because of the restriction of meshing between gear, applying external force as the dead bolt to Inner door lock can cause the gear rotation and make dead bolt indentation in lock, like this, just may open door if prize dead bolt in the interior crack between a door and its frame, and not reach the pick-proof effect with the sheet instrument.
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Inner door lock with better pick-proof effect is provided.
The utility model is to finish the invention task like this: a kind of Inner door lock, comprise panel, housing, blind hole dead bolt and through hole dead bolt, housing is connected on the panel, one end of blind hole dead bolt and through hole dead bolt passes panel, the other end is fixed on the bolt plate, be connected with back-moving spring between blind hole dead bolt inner chamber and the location-plate, the through hole by the through hole dead bolt is equipped with the taper movable lug, and connects with stage clip, corresponding taper movable lug position is provided with uncoupling rigging, the knob rotating shaft is passed the thumb wheel hole and the housing that can drive the thumb wheel rotation and is connected, and it is characterized in that pulling out between wheel and the bolt plate, connects by the connecting rod that can make its interlock.
A kind of Inner door lock, its feature be when connecting rod is vertical with bolt plate, connecting rod on bolt plate and thumb wheel tie point and the center of knob rotating shaft point-blank.
A kind of Inner door lock is characterized in that uncoupling rigging comprises locking bail, and locking bail and bolt plate flexibly connect by rivet and extension spring, and there is an anchor post that is fixed on the housing position of corresponding locking bail.
A kind of Inner door lock is characterized in that bolt plate respectively connects a world latch hook sheet in two ends up and down, and described world latch hook sheet has a skewed slot.
After adopting this structure, when Inner door lock is in locking state, connecting rod is perpendicular to bolt plate, and this time, the center of knob rotating shaft and connecting rod two tie points on bolt plate and thumb wheel form stop again point-blank, therefore, if not passing through the turning knob rotating shaft, just reinforcing just can't be opened Inner door lock on dead bolt, makes it have better pick-proof effect.
Further specify the utility model below in conjunction with Figure of description, and provide embodiment.
Fig. 1 is the structural representation that has linkage component Inner door lock opening.
Fig. 2 is the structural representation that has linkage component Inner door lock closed condition.
A kind of as shown in the figure Inner door lock, comprise panel (1), housing (2), blind hole dead bolt (3) and through hole dead bolt (4), housing (2) is connected on the panel (1), one end of blind hole dead bolt (3) and through hole dead bolt (4) passes panel (1) other end and is fixed on the bolt plate (5), be connected with back-moving spring (7) between the inner chamber of blind hole dead bolt (3) and the location-plate (6), through hole by through hole dead bolt (4) is equipped with taper movable lug (8), and in through hole, connect with stage clip (9), locking bail (13) is equipped with in the position of corresponding taper movable lug (8), locking bail (13) flexibly connects by rivet and extension spring (14) with bolt plate (5), there is an anchor post (15) that is fixed on the housing (2) corresponding locking bail (13) position, knob rotating shaft (10) is passed the thumb wheel hole and the housing (2) that can drive thumb wheel (11) rotation and is connected, flexibly connect by connecting rod (12) between thumb wheel (11) and bolt plate (5), can realize interlock, and when connecting rod (12) is vertical with bolt plate (5), connecting rod (12) on bolt plate (5) and thumb wheel (11) two tie points and the center of knob rotating shaft (10) point-blank.Like this, need only when Inner door lock is opened and rotate outer handle, pulling out wheel (11) by knob rotating shaft (10) drive rotates, drive bolt plate (5) retraction by connecting rod (12) again, when blind hole dead bolt (3) and through hole dead bolt (4) are fully retracted in the housing (2), locking bail (13) just in time is stuck on the anchor post (15), and the conical nose of taper movable lug (8) is exposed at panel (1) outside, and Inner door lock is in opening.And when closing, then need not rotate outer handle, contract in the lateral pressure compressing taper movable lug (8) that conical nose by taper movable lug (8) and the collision of interior doorframe produce, a hypotenuse of its bottom compressing locking bail (13), locking bail (13) is rotated and disengaging anchor post (15), under back-moving spring (7) effect, bolt plate (5) is rebounded, Inner door lock is in locking state, and at this moment connecting rod (12) is vertical with bolt plate (5), and knob rotating shaft (10) and two tie points of connecting rod (12) on bolt plate (5) and thumb wheel (11) are point-blank, form stop, when prizing dead bolt with external force, can't make the dead bolt retraction, played pick-proof effect preferably.
Certainly, this Inner door lock that has linkage component also can respectively connect a world latch hook sheet (16) in two ends up and down in bolt plate (5), has a skewed slot (17) on the latch hook sheet (16), can and dead bolt (3), (4) interlock.
