Abstract
The utility model relates to a knob mechanism for a door lock with a latch. A locking and unlocking structure is composed of a switch body, a cross joint axle and a switch knob, wherein, the cross joint axle is fixed in the switch body by a self shoulder and a circlip for a shaft and can rotate freely. A block at the front end of the switch knob is inserted into a block-shaped hole of the cross joint axle; the position of the switch knob in the switch knob is determined by the self shoulder and a positioning structure, and the switch knob can rotate freely; the positioning structure is composed of a steel ball, a steel ball pressure spring and a screw, wherein, the screw is screwed into the switch body and can adjust the pressure of the spring; a bolt unlocking preventing structure is composed of a switch body, a cross joint axle and an elastic cylindrical pin. The utility model has the advantage of convenient installation, and can effectively improve theftproof performance when users rest at home.
Description
The utility model relates to a kind of mortise door lock Knob mechanisms.
Common mortise door lock Knob mechanisms can only be in door the shift bar the positive and negative rotation Knob mechanisms, reach the effect of locking, unlock deadbolt.When making technical unlocking with key or with foreign matter outdoors, the dead bolt of locking can be opened.
The purpose of this utility model is to provide a kind of locking, unlock deadbolt function that not only has common mortise door lock Knob mechanisms, and can not be technical and key operated, the mortise door lock Knob mechanisms that security performance is fabulous.
The utility model is to realize like this, its structure comprises switch body, shift bar, the cross nodal axisn, circlip for shaft, elastic cylindrical pin, steel ball, the steel ball stage clip, screw, tapered end cover, gasket ring, tapered end cover and tapered end spring, switch body, the cross nodal axisn, shift bar constitutes locking, opening structure, the cross nodal axisn is fixed in the switch body by shoulder own and circlip for shaft, free to rotate, shift bar front end square inserts in the cross nodal axisn square shape hole, shift bar is determined its position in switch body by shoulder own and location structure, this position is that shift bar is in locking, open the operating position, and free to rotate; Steel ball, steel ball stage clip, screw constitute location structure, and screw screws in the switch body, and energy regulating spring pressure; Switch body, cross nodal axisn, elastic cylindrical pin formation prevent the unlock deadbolt structure, and tapered end cover, gasket ring riveting are contained on the switch body, and tapered end cover, tapered end spring are installed between switch body outside and tapered end cover and the switch body boss.
The utility model Knob mechanisms not only has the above-mentioned locking of common mortise door lock Knob mechanisms, unlock deadbolt function.When shift bar is in when preventing the unlock deadbolt operating position, elastic cylindrical pin one end is in the shift bar spline groove, and shift bar can not rotate, thereby cross nodal axisn, dead bolt driving mechanism, dead bolt can not be moved, and has reached the purpose that prevents unlock deadbolt.So the utility model be a kind of when shift bar is in can not be technical and key operated when preventing the dead bolt enable possition, the mortise door lock Knob mechanisms that safety is fabulous.
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of the utility model.
The utility model structure comprises switch body, shift bar, the cross nodal axisn, circlip for shaft, elastic cylindrical pin, steel ball, the steel ball stage clip, screw, tapered end cover, gasket ring, tapered end cover and tapered end spring, switch body (7), cross nodal axisn (6), shift bar (5) constitutes locking, opening structure, cross nodal axisn (6) is fixed in the switch body by shoulder own and circlip for shaft (9), free to rotate, shift bar (5) front end square inserts in cross nodal axisn (6) the square shape hole, shift bar (5) is determined its position in switch body (7) by shoulder own and navigation system, this position is that shift bar (5) is in locking, open the operating position, and free to rotate.With shift bar (5) forward or reverse 90 degree, shift bar (5) drives cross nodal axisn (6) and rotates, and cross nodal axisn (6) drives the interior dead bolt driving mechanism of lock gall and rotates, and the dead bolt driving mechanism drives the dead bolt locking or dead bolt is opened.Location structure comprises steel ball (10), steel ball stage clip (11), screw (12).When shift bar was in unlatching, locking operating position, steel ball was compressed in the living shift bar annular arc groove by the steel ball stage clip, and when guaranteeing that door is subjected to external force vibration, shift bar can not slide into automatically and prevent the unlock deadbolt operating position from locking, unlatching operating position automatically.Screw (12) is to screw in the switch body, and can regulating spring pressure.Prevent the unlock deadbolt structure, comprise switch body (7), cross nodal axisn (6), elastic cylindrical pin (8).When door is closed, rotating switch handle (5) makes the tapered end locking.Shift bar (5) is pulled out, and at this moment, steel ball breaks away from the shift bar arc groove, and elastic cylindrical pin one end is in the shift bar spline groove, and shift bar can not be rotated, and can not continue to pull out.Elastic cylindrical pin (8) other end is to press fit on the switch body (7).At this moment, technical even use when key operated with foreign matter outdoors, because the dead bolt driving machine is rotated and the dead bolt retraction, but, unlock deadbolt rotates because of can driving the dead bolt driving mechanism, the dead bolt driving mechanism rotates and can drive cross nodal axisn (6) rotation, and cross nodal axisn (6) rotation can drive shift bar (5) and rotate, and shift bar (5) can't rotate it because of elastic cylindrical pin (8) one ends in its spline groove, so said mechanism or part can not move, dead bolt can not be opened.Flicking shift bar (5), shift bar (5) are promptly got back to unlatching, locking dead bolt operating position.
Tapered end cover (1), gasket ring (2) riveting are contained on the switch body (7), and tapered end cover (4), tapered end spring (3) are mounted between switch body (7) outside and tapered end cover and switch body (7) boss, play decoration, positioning action.
Switch body (7) has two pin-and-holes, utilizes two latches that add to pass two pin-and-holes, just switch body can be fixed on the lock gall.
In sum, the utility model knob mechanism for latch door lock have unlatching, the locking dead bolt and Prevent from opening two kinds of functions of dead bolt. It has simple and reasonable, and is easy for installation, especially effective Ground has improved be in theftproof performance after having a rest of user.
Claims (2)
1, a kind of mortise door lock Knob mechanisms, its feature comprises switch body in its structure, shift bar, the cross nodal axisn, circlip for shaft, elastic cylindrical pin, steel ball, the steel ball stage clip, screw, tapered end cover, gasket ring, tapered end cover and tapered end spring, switch body, the cross nodal axisn, shift bar constitutes locking, opening structure, the cross nodal axisn is fixed in the switch body by shoulder own and circlip for shaft, free to rotate, shift bar front end square inserts in the cross nodal axisn square shape hole, shift bar is determined its position in switch body by shoulder own and location structure, this position is that shift bar is in locking, open the operating position, and free to rotate; Steel ball, steel ball stage clip, screw constitute location structure, and screw screws in the switch body, and energy regulating spring pressure; Switch body, cross nodal axisn, elastic cylindrical pin formation prevent the unlock deadbolt structure, and tapered end cover, gasket ring riveting are contained on the switch body, and tapered end cover, tapered end spring are installed between switch body outside and tapered end cover and the switch body boss.
