Description

A biparting drive lock that moves

The utility model relates to the lock class, in particular for the biparting lock that moves on the door.

Biparting sliding door lock is used for the biparting locking that moves door.Modern Family, market, hotel are efficient in order to improve usable floor area when upholster, often adopt portable door, and the biparting application that moves door of especially splitting is more and more general, and therefore corresponding biparting sliding door lock is also more and more paid attention to.Existing biparting sliding door lock is because the axle center of the axle center of key and dead bolt not on same coordinate direction, forms 90 ° of corners, not only operation inconvenience, and can't move a supporting use with slim plastic-steel is biparting.

The purpose of this utility model be to overcome the defective of prior art and provide a kind of easy and simple to handle and can with slim plastic-steel biparting move the door a matching used biparting drive lock that moves.

Its embodiment is: comprise lock construction that is arranged on the interior wing door and the keeper that is arranged on the exterior wing door, described lock construction comprises directly by the spring bolt mechanism of manual knob unlatching and the lock core mechanism of being opened indirectly by key, it is characterized in that described lock core mechanism axle center and spring bolt mechanism axle center are on the same coordinate direction, and interrelate by transmission mechanism, this transmission mechanism comprises the worm screw wheel with the synchronous rotation of lock core that is fixed on the lock core inner face, also can stir the link supporting of spring bolt mechanism on lock core shell with the worm gear of worm screw wheel engagement by what be in transmission connection with it.

The utility model because of the design of lock core mechanism axle center and spring bolt mechanism axle center on same coordinate direction, be convenient to people's operation, also be suitable for moving the supporting use of door, but move a door bidirectional opening after unblanking with slim plastic-steel is biparting, this lock construction is simple, locking safety.

Below with reference to above-mentioned accompanying drawing the embodiment of the utility model is remake and to specify.

The biparting drive lock (referring to Fig. 1-7) that moves moves door motion in use not in same plane owing to biparting, two are operated in separately in the track, two door shelves just overlap before and after when closing, and this lock just is mounted on the suitable height of shelves center position, inside and outsidely all can open and close.The keeper (26) that comprises the mutually supporting lock construction that is arranged on interior wing door (24) and be arranged on exterior wing door (25) (Fig. 6).

Described lock construction comprises directly by the spring bolt mechanism of indoor manual knob (9) unlatching and the lock core mechanism (Fig. 7) of being opened indirectly by outdoor key (27), and lock core mechanism axle center and spring bolt mechanism axle center are on the same coordinate direction, and interrelate by transmission mechanism, when promptly opening the lock with the key, come indirect operation to stir spring bolt mechanism by transmission mechanism.

Described spring bolt mechanism includes a lock housing (6) and a locking closure (4) fastened to each other, in be provided with telescopic dead bolt (5), this dead bolt is by two block length steel plates, in clip two blocks of short steel plates and be fixed with one, the horizontal groove of middle formation, the middle part boss is a left side, right limit shoulder (21), (14), be provided with suitable two the tooth supports (7) hinged of thickness in the groove with it, and be symmetrical arranged, hinged point is respectively (16), (18), and two spacing points (17) that the tooth support is closed up, curved dead bolt hook (22) in the head of tooth support and afterbody all are, be provided with stage clip (23) between two tooth supports, when this stage clip contracts opening in dead bolt two tooth support afterbodys are backed down, lock is opened smoothly.Be located at the outer manual knob (9) of lock housing and be fixed with one with the dial (11) that is located at the lock housing internal chamber wall, this dial is done synchronous revolution with the rotation of knob, and the centre of dial is provided with fan-shaped cross bore (19), stirs usefulness for the connecting rod (3) of transmission mechanism.The eccentric position of dial is provided with the bearing pin (15) of close-fitting, be provided with extension spring (20) between it and the dead bolt, this bearing pin tightly leans when lock is in locking states on the afterbody dead bolt hook of a tooth support, when making the tooth support extend in the keeper hole, the tooth support launches, and the dead bolt of head hooks and tightly catches on keeper, two fans move door and promptly are closed, prevent that dead bolt from returning the position, guarantee locking firmly (Fig. 4), bearing pin pushes be close to dead bolt left limit shoulder to lock housing inside wall (Fig. 5) again when the lock opening.

Lock core mechanism is handled by key (27) and opens, be routine techniques, key is a long handle type, long handle partly inserts in the lock core hole of interior wing door by the hole of exterior wing door, but lock core shell (1) structure is improved, lock core mechanism and spring bolt mechanism are interrelated by transmission mechanism, and the axle center of lock core mechanism and the axle center of spring bolt mechanism are on the same coordinate direction.

Transmission mechanism comprises with the worm gear (12) of two screw on lock core (2) inner face, it rotates synchronously with lock core, be located on the connecting rod (3) that to stir spring bolt mechanism with the worm gear (10) of worm screw wheel engagement, worm gear and the feather joint of connecting rod side form drive connection, and link supporting is spacing by back-up ring in the lock core shell axis hole, afterbody at lock core shell extends two sidewalls with bearing connecting rod for this reason, and link rod head is the in-line structure, inserts in the dial central sector cross bore.Worm screw wheel is the helical gear structure with worm gear, and worm screw is taken turns 10 teeth, and worm gear 18 teeth make gearratio less than 2, promptly when key turns during less than ± 180 °, connecting rod only rotates ± 90 ° just can make the spring bolt mechanism keying.

Originally the homonymy that is locked in manual knob is provided with the flexible insurance institution of restriction dead bolt, it comprises the stop button (8) that can stir slippage up and down, stop button is contained in to be done upper and lower slippage along this elongated slot in the lock housing elongated slot and stirs, be provided with the safety plate (13) that is fixed as one with stop button in the lock housing internal chamber wall chute, safety plate can slide up and down in the chute of two projectioies of lock housing internal chamber wall, when safety plate slides when leaning against dead bolt right limit shoulder (14), make opening safety, don't work knob this moment might as well, key all can't be locked again.No matter when leaning against left limit shoulder (21), do the locking insurance, be with indoor knob or outdoor key, also lock can't be opened.Only after arming, the just keying that can do to lock, upward be disarm state as long as stop button (8) dialled this moment.
