Abstract

The utility model provides a lock with a bolt unlocking and ejecting structure, which is mainly composed of a bamboo joint-shaped lock strip (10), a lock body (1), a lock bolt (7) and a plug (2) connected with the lock strip, wherein the upper end of the lock bolt is provided with a groove (8), and one side of the lock body is fixed with a positioning pin (4) corresponding to the groove of the lock bolt. When unlocked, the lock bolt is naturally ejected through the slide of the positioning pin in the groove of the lock core, and a key is fixed on the lock so as to prevent from being lost. Because the end of the lock core is designed to a small cylinder which is in integral forming with the lock bolt through casting, components, such as a lock latch, etc. are saved so that the utility model has the advantages of processing technique simplification and easy assembly.

Description

Core is opened ejecting structure joint lock

The utility model relates to ejecting structure is opened in a kind of daily life with particularly a kind of core of lockset joint lock

Lockset of the prior art, its lock body adopts general structure, in lock body, remove lock core is housed, also component such as dead bolt and shifting block need be set, thereby cause complex structure, processing technology is cumbersome, be difficult to once assemble success, open the back because of the lock core structure cause at lock, also need key is extracted, otherwise lose key easily.

The purpose of this utility model provides a kind of processing technology to be simplified, and is easy to assembling, and the core that need not to pull key after unblanking is opened ejecting structure joint lock.

The utility model is realized by following measure:

Core is opened ejecting structure joint lock and mainly is by ring shape bolt, moulds cover, lock body, lock core and the plug that is connected with bolt and constitute, lock core has a L-shaped groove near the upper end, lock body one side corresponding to L shaped groove position intrinsic one and lock core shaft to vertical alignment pin, alignment pin rotates with lock core and slides in L shaped groove and the location, lock core one end is and the small cylinder of lock core integral die-cast moulding that small cylinder is provided with the tower spring.

Description of drawings:

Fig. 1 is the structural representation that core is opened ejecting structure joint lock;

Fig. 2 is that core is opened ejecting structure joint locking bit pin drawing of site.

Below in conjunction with accompanying drawing the utility model is further described:

Core is opened ejecting structure joint lockset ring shape bolt (10), lock body (1), lock core (7) and the plug (2) that is connected with bolt (10), a plurality of pages of sheets (5) and corresponding page or leaf sheet spring (6) are housed being on the cylindricality lock core of garden, lock core has a L shaped groove (8) near the upper end, lock body one side corresponding to L shaped groove position intrinsic one and lock core shaft to vertical alignment pin (4), by alignment pin along sliding in the L shaped groove and the location, lock core is ejected when opening, the small cylinder (9) of lock core one termination system and the moulding of lock core integral die-cast, the small cylinder diameter is provided with tower spring (3) less than lock core diameter in the outside of small cylinder.

Core is opened the ejecting structure joint and is locked when being in blocking, the small cylinder (9) of lock core (7) end is stuck in the plug (2) by the lock body mesopore, at this moment alignment pin (4) is in the L shaped groove of lock core (8) transverse groove, when key operated lock, when the lock core key rotated with spoon, the tower spring on the small cylinder was upspring, lock core is withdrawed from from plug, alignment pin is slided in the cannelure by transverse groove in the L shaped groove of lock core, and lock core is ejected naturally, and key is fixed on the lock core.

The utility model has the advantage of: the one lock core adopts L shaped groove and locating pin structure, unblanks After key is fixed on the lock core, need not it is extracted, with Anti-lost key; Its two lock core one The termination is designed to the small cylinder with the lock core global formation, has saved the in addition parts such as dead bolt, thereby Simplified processing process is easy to assembling, and this lockset has the product design fineness, the characteristics that applicability is wide.

Claims

1 one kinds of cores are opened ejecting structure joint lock, and it mainly is by ring shape bolt (10), lock body (1), lock core (7) and plug (2) constitute, it is characterized in that lock core (7) has a L shaped groove (8) near the upper end, in lock body one side corresponding to L shaped groove position intrinsic one and lock core shaft to vertical alignment pin (4), the alignment pin location of in L shaped groove, sliding, lock core one end is and the small cylinder (9) of lock core global formation, is provided with tower spring (3) thereon.
