Description

A kind of door lock

Technical field

The utility model relates to articles for daily use, specially refers to the door lock that oblique tongue can commutate.

Background technology

Before the utility model proposes, as the door lock of articles for daily use, very be applied at large on all kinds of door, very many kind, specification and model are arranged.In general, on the housing of door lock, have door-opening mechanism and lock door mechanism.Described door-opening mechanism comprises the oblique tongue that has oblique tongue rod, draws together a plate with oblique tongue contacts closely, draws together to establish in the plate and draws together a hole, rotates and is located at the handle of drawing together in the hole in, oblique tongue is stretched out or is retracted into panel hole, closes or opens thereby make.The described lock door mechanism side of comprising tongue, lock core hole and lock core shift fork, connecting rod.Connecting rod and square tongue, lock core shift fork are in contact with one another.When key inserted lock core hole and rotates, through the lock core shift fork, connecting rod, the side's of making tongue stretched out or are retracted into panel hole, thereby lock is opened or closed.Meanwhile, connecting rod is in contact with one another with drawing together a plate again, and the key in the insertion lock core hole also can make oblique tongue stretch out simultaneously or be retracted into panel hole, and then makes door close or open.But for the convenience of open and close door, the oblique tongue on the general door lock all is made into one side and is the plane, and another side is the inclined-plane.Utilize the laborsaving principle on inclined-plane, at closing time as long as door is promoted lightly, tiltedly the inclined-plane of tongue just can get on the doorframe accordingly in the hole very like a cork.And when door when being shut,, can not push the door open like a cork owing to receive the stopping of plane of oblique tongue, must swing handle or key just can open the door.Door is arranged in the doorframe, is divided into two kinds of L.H.flapped door and R.H.flapped doors.Door lock also must be divided into left hand model and right hand model like this, and ten million cannot oppositely install.Do not join door lock in case drive to come, just need the bevel direction of the oblique tongue of adjustment with the right side by the left side of door.At this moment will pull down door lock earlier, the employing instrument outwards ejects the oblique tongue rod on the oblique tongue panel and rotates oblique tongue rod, and the Dou tongue rotates thereupon, up to the inclined-plane of oblique tongue be positioned at open the door must the position till, reinstall the on-off mode that door lock makes it coincidence gate then.Such adjustment operation is very inconvenient, also will ask the professional to help sometimes.

Summary of the invention

The technical problem that the utility model will solve is to overcome deficiency of the prior art, and a kind of novel door lock is provided.In door lock, tiltedly the tongue direction can change arbitrarily, and it is very easy to change the operation of oblique tongue direction.

The utility model is to realize through following technical measures.A kind of door lock comprises housing, the panel that is fixedly connected with housing; Be arranged on door-opening mechanism and lock door mechanism on the housing; Also comprise the oblique tongue that is arranged in the door-opening mechanism, an end is connected the oblique tongue rod that also can rotate with tiltedly tongue fixed connection, the other end with oblique tongue spacer; Be fixed on the fastening post on the housing; Be installed in the Inclined bolt direction changing piece on the described fastening post; Convexity on the Inclined bolt direction changing piece is installed in the Inclined bolt direction changing hole of housing; On the Inclined bolt direction changing piece, be provided with oblique gyrus lingulais position spring, tiltedly an end of gyrus lingulais position spring is arranged on the Inclined bolt direction changing piece, and the other end is arranged on the oblique tongue spacer.

The described oblique tongue spacer that in the chute of housing, moves is cross, and oblique tongue rod is positioned at the centre of described oblique tongue spacer.

After the utility model adopts abovementioned technology, when door lock is installed or changed, needn't consider that a left side is driveed with the right side to open.Only need pull the bossing on the Inclined bolt direction changing piece, make oblique tongue stretch out housing, manually rotate oblique tongue, can easily accomplish the switching-over of oblique tongue, a left side open or the right door lock of opening just switching-over become that open on the right side or open on a left side.Operation is very simple, and is convenient.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is an A portion enlarged drawing among Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Embodiment: as depicted in figs. 1 and 2, a kind of door lock comprises housing 1, the panel 2 that is fixedly connected with housing 1; Be arranged on door-opening mechanism 3 and lock door mechanism 4 on the housing 1; Also comprise the oblique tongue 5 that can in panel inclined tongue hole 14, move that is arranged in the door-opening mechanism 3; The oblique tongue rod 6 that one end and tiltedly tongue 5 fixed connections, the other end are connected with oblique tongue spacer 7; Tiltedly tongue spacer 7 is cross, and can in the chute 13 of housing 1, move, and oblique tongue rod 6 is positioned at the centre of described oblique tongue spacer 7, and can rotate with respect to oblique tongue spacer 7 with oblique tongue 5.

Be fixed on the fastening post 8 on the housing 1, be installed in the Inclined bolt direction changing piece 9 on the described fastening post 8, the convexity 10 on the Inclined bolt direction changing piece 9 is installed in the Inclined bolt direction changing hole 11 of housing 1, can in Inclined bolt direction changing hole 11, move around.On Inclined bolt direction changing piece 9, be provided with oblique gyrus lingulais position spring 12, tiltedly tongue return spring 12 is a torsionspring, and tiltedly an arm of gyrus lingulais position spring 12 is arranged on the Inclined bolt direction changing piece 9, and another arm is arranged on the oblique tongue spacer 7.
