Abstract

The utility model relates to a structure modified lock which belongs to lockset, comprising a lock case 2, a lock core 8, a lock core seat 5, a bolt 1 and a lock cap 15. A guide pillar 10 is arranged at the lower part in the lock case 2. A rack 12 which can slide left and right is arranged on the guide pillar 10. The base part of the bolt 1 is fixedly arranged on the rack 12. A gear 9 is fixedly arranged on the lock core 8. The gear 9 is engaged and matched with the rack 12. When the lock core 8 rotates clockwise/anticlockwise by 90 DEGS, the bolt 1 stretches or shrinks enough length. Thus, the utility model has the advantages of reliable lock and safety.

Description

Structure improved lock

The utility model discloses a kind of structure improved lock, belong to lockset.

Existing lock, general all is that base portion with dead bolt directly is installed with and is being connected with dead bolt on the lock core or by the parts that are fixed on shifting block on the lock core and so on, along with key suitable/the contrary lock core that twists, in the time of the lock core rotation, make dead bolt also do corresponding the stretching, extension or rollback, to realize unlatching/locking.But, directly or indirectly drive dead bolt with lock core and often have some limitation, for example, for some such as the used rolling-gate of commercial StoreFront, opening or during locking, often only require lock core suitable/contrary rotation respectively is 90 °, i.e. 90 ° of conrotatorys are for opening, be locking against revolving 90 °, so just reached convenient, fast effect.Therefore, if adopt said structure, the spread length of dead bolt just can't reach requirement, and the spread length of dead bolt plays crucial effect to safety.If under locking states, dead bolt is fastened with a bolt or latch into too short or said shallowly, easily brings by the anxiety of facility on the sled.

The purpose of this utility model is will provide a kind of to do at lock core under suitable/contrary half-twist, can make the stretching, extension of dead bolt or rollback reach lock sufficient length, that locking is reliable, safe structure improves.

The purpose of this utility model reaches like this, a kind of structure improved lock, form by lock housing 2, lock core 8, lock core base 5, dead bolt 1, locking closure 15, below in the described lock housing 2 is provided with guide pillar 10, guide pillar 10 is provided with a tooth bar that can horizontally slip 12, and the base portion of dead bolt 1 is installed with on tooth bar 12; Be installed with a gear 9 on the described lock core 8, gear 9 is nibbled with tooth bar 12 and is joined.

The utility model has at lock core 8 and does to make dead bolt 1 realize stretching or enough reliable, the safe advantages of length, locking of rollback under suitable/contrary half-twist owing to done above-mentioned improvement.

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

Accompanying drawing is the utility model assembling assumption diagram.

One side of tooth bar 12 of the present utility model offers chute 11, and an end of guide pillar 10 and lock housing 2 are fixing, and the other end is corresponding in the chute 11.

Lock core base 5 of the present utility model is fixed on the lock housing 2, and an end is positioned at outside the lock housing 2, and the other end then is positioned at lock housing 2.Specifically: fix earlier a mounting 6 in lock housing 2, then lock core base 5 and mounting 6 are fixed, fixing can being screwed also can be fixing with welding.Lock core 8 is arranged in the lock core base 5, and the end at the lock core 8 that is positioned at lock housing 2 is nested with gear 9 then, and is fixed with jump ring 3, in order to avoid gear 9 comes off from lock core 8.The two is fully meshed on same horizontal plane in order to make gear 9 and tooth bar 12, therefore, can realize by adding backing plate 7.Locking closure 15 is consolidated with lock housing 2 mutually by screw 14, and after consolidating mutually, the lock core hole 13 on the locking closure 15 is just in alignment with lock core 8.

The utility model is to open like this or locking, in this way in off position down, so, as long as key 4 is inserted lock core 8 and twists 90 °, the just corresponding half-twist of lock core 8 to a side, the gear 9 that the drive dress is consolidated on it also rotates to an angle, because gear 9 is meshed with tooth bar 12, so along with the rotation of gear 9, drive tooth bar 12 is to a side slip, base portion is fixed in the dead bolt 1 retraction lock housing 2 on the tooth bar 12, thereby realizes opening.Otherwise then be locking.Open or locking indoor in this way, so,, get final product according to the aforesaid way operation as long as key 4 is inserted lock core 8 in lock core hole 13.
