Description

Locking mechanism of billiard latch

Technical field under the utility model is a lock.

The function of lock is antitheft, its reliability particular importance.The locking mechanism great majority of traditional locks are to be pushed away in the breach of locking bolt insertion latch hook by spring, stop withdrawing from of latch hook; Also some is by the spring force tension or compresses a pair of pincerlike hook, hooks two hangnail faces of arrow-shaped latch hook, stops it to withdraw from.Their weakness is because this structure is normally closed structure on the one hand.Want a lock to lock, just must push locking bolt or pincerlike hook open when inserting latch hook, latch hook just can enter.Therefore one side must be arranged is band Dou face or curved surface, could produce a transverse component and push locking bolt or pincerlike hook open.Because be subjected to the restriction of size, latch hook and locking bolt or latch hook and the mutually perpendicular shift motion of this both direction of pincerlike hook all can not be oversize.In order to look after occlusal size, stroke can not be too short.So the inclination angle of Dou face is generally about 45 °.In like manner the radius of curvature of curved surface can not be too little.Thereby transverse component is just less.Therefore the action of locking is required great effort very much.And locking bolt inserts live part that latch hook breach or pincerlike hook hook the arrow-shaped latch hook seldom; Its vertical section is again a lozenges, thereby intensity is not high.Under big slightly external impacts, be subjected to the shearing force effect, may cut off, lose anti-theft feature; On the other hand, because it is the locking function of keeping locking bolt or pincerlike hook by elastic force, just might inserts foreign matter in the slit if any the slit existence and it is backed down and lose anti-theft feature.In fact, the existence in this slit can not be exempted under many circumstances.

Another kind is to be changeed in the breach of latch hook by eccentric boss in lock core end or side cuts, stops latch hook to withdraw from.Though it is not to keep locking function by elastic force, because the lock core size is limited, its corner is also limited, thereby the part that changes latch hook over to seldom, and mechanical strength is very low, under big slightly external impacts, is easy to be sheared power equally and cuts off.Lose anti-theft feature.

Two tongues are arranged certainly at present, the lock of three tongues, reliability is higher, but since complex structure, complex operation, and fault rate increases relatively, and cost of production is also high.
