Description

Make things convenient for lock core and key with spoon

Technical field

The utility model belongs to field of lockset, and particularly a kind of spoon together makes things convenient for lock core and key.

Background technology

At present traditional mechanical billiard lockset all is that a key can only be opened a lock set, and key can not be shared, so people just need wear many keys when using many cover locksets in life, carries and use all inconveniences.

The utility model content

The technical problems to be solved in the utility model provide a kind of can shared one the lock core of key unlocking and key.

The utility model solves the problems of the technologies described above with following technical scheme: the lock core of every lock only has row's pellet shot from a slingshot passage; The shape and the key of lockhole are complementary; The flank of tooth of unblanking that has two locks on the key at least.

Lockhole shape and key tail end shape of cross section can be approximate " one " font, and the flank of tooth of unblanking of two locks is arranged accordingly on the key.

Lockhole shape and key tail end shape of cross section also can be " ten " font, and the flank of tooth of unblanking of four locks is arranged accordingly on the key.

Lock core also can constitute by changeing core, greater trochanter and core retainer plate, greater trochanter places in the core retainer plate, changeing core places in the trochiterian through hole, core retainer plate and greater trochanter have row's pellet shot from a slingshot passage, change on the core having lockhole and key groove, strip groove, cylinder shape groove and the locating groove suitable, adjustment sheet is arranged on the locating groove with key tail end shape of cross section; There is the screw that places on the step of greater trochanter end the rear end of changeing core; The greater trochanter inwall axially has the groove that inserts for key, and there is the screw that places on the step of core retainer plate end its rear end; The rear end of core retainer plate has annular groove; The flank of tooth of unblanking of assembling many locks on the key flank of tooth.

The pellet shot from a slingshot top of dropping on the strip groove is that cylinder, bottom are flat cuboid, and the bottom is an arc surface.

Use lock of the present utility model and key, the flank of tooth of unblanking of many locks can be concentrated on one on the key, solve to use many troubles that lock must carry many keys, uses also easily, and can improve the safety performance of locking.

The specific embodiment

When key of two sealed usefulness, used lock core can be made into lock core 1 as shown in Figure 1, one row's pellet shot from a slingshot passage is only arranged on the lock core 1, the shape of its lockhole 2 and key 3 tail end shape of cross sections are approximate " one " font, and two flank of tooth of key 3 are respectively two flank of tooth of unblanking that specification is identical, pellet shot from a slingshot is arranged different locks.

When key of four sealed usefulness, used lock core can be made into lock core 4 as shown in Figure 3, one row's pellet shot from a slingshot passage is only arranged on the lock core 4, the shape of its lockhole 5 and key 6 tail end shape of cross sections are " ten " font, and four flank of tooth of key 6 are respectively four flank of tooth of unblanking that specification is identical, pellet shot from a slingshot is arranged different locks.

When five locks or five during key of above sealed usefulness, used lock core can be made into lock core as shown in Figure 5, it is by changeing core 15, greater trochanter 14 and core retainer plate 13 constitute, greater trochanter 14 places in the core retainer plate 13, changeing core 15 places in the through hole of greater trochanter 14, core retainer plate 13 and greater trochanter 14 have row's pellet shot from a slingshot passage, be placed with spring 11 in the passage, pellet shot from a slingshot 12, change on the core 15 and have lockhole 16, key groove 19, two row's strip grooves 18 and 21, two cylinder shape grooves 17 and 22 and locating groove 20, the shape of lockhole 16 is closely " one " font with the key 26 tail end shape of cross sections of unblanking, adjustment sheet 10 is arranged on the locating groove 20, key groove 19 communicates with strip groove 21 and cylinder shape groove 22, and there is the screw 7 that can touch greater trochanter end step 24 rear end of changeing core 15; The greater trochanter inwall axially has the groove 23 that inserts for key, and there is the screw 8 that can touch core retainer plate end step 25 its rear end; The inner surface of core retainer plate 13 has annular groove 9; Unblank the tooth depth of key 26 first teeth of tail end greater than the tooth depth of all the other teeth, assembled the flank of tooth of unblanking of many locks on its flank of tooth.The pellet shot from a slingshot top of dropping on the strip groove is that cylinder, bottom are similar to flat cuboid, the bottom is an arc surface, remaining pellet shot from a slingshot is a cylinder, when greater trochanter 14 communicates with the pellet shot from a slingshot passage of core retainer plate 13, because the pellet shot from a slingshot bottom that contacts with the commentaries on classics core is arc surface, can not block the commentaries on classics core, change the rotation that core can be made certain angle.

When needs are unblanked, stir commentaries on classics core 15 with the key tail end, when lockhole 16 is communicated with trochiterian groove 23, just whole key can be inserted in the lockhole, block until being conditioned sheet 10, at this moment key makes changes core 15 rotations, when the flank of tooth of key goes to when corresponding with the pellet shot from a slingshot passage, pellet shot from a slingshot just drops on the flank of tooth of key, at this moment, does not have pellet shot from a slingshot to connect between greater trochanter and the core retainer plate, the screw 7 that changes the core rear end also just is being stuck on the greater trochanter end step 24, be rotated further the commentaries on classics core again, screw 7 just drives greater trochanter and rotates, and can realize unblanking.Trochiterian screw 8 is stuck on the core retainer plate end step 25, can limit trochiterian rotational angle.

When needs are extracted key out, key is pressed counter-rotation, the cylinder-shaped marble that drops on the cylinder shape groove 22 can drive greater trochanter 14 rotations, when going to greater trochanter when communicating with the pellet shot from a slingshot passage of core retainer plate, trochiterian screw 8 just in time blocks core retainer plate, and greater trochanter just stops operating, and is rotated further the commentaries on classics core again, when going to when communicating, just can transfer to key with trochiterian groove 23.When locking, pellet shot from a slingshot can fall into strip groove 18 and cylinder shape groove 17 to alleviate spring pressure.

When needs are locked, its operating procedure and the step basically identical of unblanking, just, will change core with key and make trochiterian screw 8 fall into annular groove 9, and can realize locking with the outside pull of greater trochanter going to when not having pellet shot from a slingshot to be connected between greater trochanter and the core retainer plate.

Because the pellet shot from a slingshot that drops on the strip groove is inclined to one side shape, the contact surface of itself and key is less, makes the flank of tooth of a key that the flank of tooth of unblanking of many locks can be set; Adjustment sheet is stuck on the different draw-in grooves, makes pellet shot from a slingshot different with the contact site of key, thereby makes a key can adjust the flank of tooth of unblanking of many locks.
