Description
Technical field
The present invention relates to a kind of five metals door lock fittings, especially antitheft lock parts.
Background technology
At present, it is three circle torsion springs that the square tongue that market extensively uses dials peach auxiliary rotary part, and this kind of lock body is installed cumbersome, and use feel not good, and mechanical part collides with each other, noise is larger.
Summary of the invention
The invention provides a kind of lock body side tongue detent mechanism, its objective is and improve installation situation, improve lock body and use feel, reach good muting function, be applicable to family and the office door lock of various building.
The technical solution used in the present invention is: establish a box bottom component, side's tongue dials peach assembly, side's tongue assembly and a shell fragment.Described box bottom component is provided with square bolt hole, core dials peach and positioning guide column; Described side's tongue dials that the peach assembly side of being provided with tongue dials peach plate, square tongue dials peach, axle sleeve and axle, side's tongue is dialled in the middle of peach plate and is provided with locating hole A, locating hole B is provided with on locating hole A side, side's tongue is dialled peach and is provided with locating hole C, stirs groove and locating hole D, be provided with reference column to coordinate with the locating hole B that square tongue dials peach plate on locating hole C side, square tongue is dialled peach side and is provided with the first lock face and the second lock face; Described side's tongue assembly side of being provided with tongue, square hyoplastron, square tongue accessory plate, bearing pin and connecting axle, described side's hyoplastron front end is provided with sliding tray A, establishes through hole A and through hole B on sliding tray A side, and square hyoplastron rear end is provided with sliding tray B; Described side's tongue accessory plate is provided with through hole C and through hole D; An annular ring is established in described shell fragment one end.The assembly relation of each component is: the annular ring on shell fragment is arranged on the shell fragment reference column in box bottom component, then the other end is pressed on the shell fragment locating piece in box bottom component, side's tongue is dialled peach plate and is inserted in the first lock face (or second lock face) being pressed on its side on positioning guide column and by shell fragment by its locating hole A, axle is arranged in axle sleeve and the side of being through at tongue and dials in the locating hole D of peach fastening, side's tongue is dialled peach and is inserted on positioning guide column by its locating hole C, and the reference column side of the being arranged in tongue dialled by square tongue on peach is dialled in the locating hole B on peach plate; On the side's tongue side of being anchored on hyoplastron, side tongue accessory plate through hole C coordinates with pinned connection with the through hole B of square hyoplastron, through hole D is connected with through hole A cooperation connecting axle, thus the side's of formation tongue assembly, square tongue assembly is positioned in box bottom component, side's tongue is placed in square bolt hole, and sliding tray A is placed on axle sleeve, and sliding tray B is placed on positioning guide column.
Under free state, side's gyrus lingulais is received, side's tongue dials the top of the sliding tray A of the peach side of being still in hyoplastron, shell fragment has dialled peach plate side the first lock face with square tongue compresses and is in compressive state and forms lock-bit, when needs are locked, lock core is dialled the peach side of stirring tongue and is dialled peach stirs groove, the side's of making tongue is dialled peach and is counterclockwise rotated, shell fragment is dialled peach plate due to the side's of being subject to tongue and is extruded, elastic deformation is increasing, shell fragment the other side tongue is dialled peach plate pressure and is become large gradually, when having crossed critical point, side's tongue is dialled peach plate and is intermittently rotated counterclockwise under shell fragment pressure, thus drive whole side's tongue to dial the rotation of peach assembly, square tongue is released by axle and axle sleeve slide downward completely, now, the second lock face that shell fragment and square tongue dial peach plate side compresses and is in compressive state and forms lock-bit, dial in peach assembly rotation process at square tongue, the stepless change of elastic force of shell fragment, side tongue stretch out completely state with reclaim time, the contact compressive state that shell fragment and square tongue dial peach plate is completely the same, can the side's of making tongue indentation with all there is when stretching out the same lock-bit effect.
The useful technique effect that the present invention produces is: dial in the process of peach rotation at square tongue, owing to can relatively rotate between axle and axle sleeve, and in lock body design, lock body is that single-stage locks (square tongue can one-time-reach-place) when locking, and so just makes enabling, it is more smooth to close the door; When square tongue dial peach square tongue toggled it to lock extreme position time, the sliding tray A low side of axle and the axle sleeve side of staying in hyoplastron, the second lock face that shell fragment and square tongue dial peach plate side contacts and compresses formation self-locking state; If when square tongue is subject to external force, by square tongue accessory plate, external force is decomposed into effect to square tongue and dials the component of peach and act on the component of box bottom component, the side's of making tongue supports more firm like this; Present invention improves mounting structure, improve lock body and use feel, reach good muting function.
