Abstract
The utility model relates to a lock core device and the key thereof. An inner round hole used for containing a lock core is arranged on a casing barrel; a positioning pin is used for limiting the lock core to rotate in a definite angle; the inner round hole and the positioning pin are provided with a plurality of pairwise engaged pin ball holes which are used for placing lower pin balls and elastic elements and are sealed by a cover. The utility model is characterized in that more than two keyholes are arranged on the lock core, the keyholes are communicated with a plurality of pin ball holes corresponding to the keyholes; the key is provided with a column rod conforming to the lock core; when the key is inserted, the lower pin balls can be pushed to stop at a proper height and turns the lock core. The utility model has more and more complicated changing functions, and improves the anti-theft performance of the lock.
Description
The utility model relates to a kind of lock device, particularly relates to a kind of lock cylinder device and key thereof of lockset.
Traditional lockset lock cylinder device, be to go into to have rotatable core so that an outer thimble is built-in, core has with outer thimble can be kept supplying the pin pearl hole of nibbling, lower pin pearl and flexible member are inserted, the known core of this kind is that a keyhole is only arranged, and this keyhole can connect with pin pearl hole, and the different groove of the depth is arranged on the key, can promote for the correct key of profile of tooth, the lower pin pearl lifting, the defiber of lower pin pearl can be formed nibbling or separating with the defiber that core reaches outer thimble, so that whether core can form rotation, the known lockset of this kind has following shortcoming: when (one) key became positive toroidal, this key need be established in addition and drive groove and drive the core rotation together.(2) thief is easy to the pin pearl be picked one by one to pick flowing mode by keyhole, to reach the purpose of its stealing.
The purpose of this utility model, be to overcome the defective on the prior art, and provide a kind of lock cylinder device and key thereof of lockset, make core be provided with keyhole more than two, can insert for the key that is provided with the mast that is consistent with it, make this core have more, more complicated variation function, increase the difficulty of thief's pirate of the open, and improve the theftproof performance of lockset.
The purpose of this utility model is realized by following technical scheme.A kind of lock cylinder device of lockset, its be beyond thimble be provided with for core hold into interior circular hole, and with the rotation of alignment pin restriction core fixed angle, the two be provided with for down, lower pin pearl and flexible member is inserted several pin pearl holes of paired engagement and close with cap seal, it is characterized in that: core is provided with the keyhole more than two, each connects keyhole with several pin pearl holes corresponding with it, and correct shape key inserts in the keyhole, promotes lower pin pearl and rests on suitable height and revolving plug.
The purpose of this utility model also can further be realized by following technical measures.A kind of key of lockset, it is inserted in the keyhole of core with mast; This mast is provided with the groove of different depth, makes the pin pearl rest on suitable height, it is characterized in that: described mast is the number that is provided with more than two.
The utility model compared with prior art has the following advantages and effect.By above technical scheme as can be known, because it adopts core to be provided with keyhole more than two, can insert for the key that is provided with the mast that is consistent with it, it is more that this core is had, more complicated variation performance and key are provided with the mast more than two, therefore, key can form the drive element by mast, and the thief is when pirate of the open, owing to doing pirate of the open simultaneously to the pin pearl in two keyholes, therefore, the difficulty of thief's pirate of the open is greatly increased, thereby improved the theftproof performance of lockset greatly, should really be initiative by structure again, and have practicality, be a novel structure in fact, be suitable for practical new design.
Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Fig. 1 is a three-dimensional exploded view of the present utility model.
Fig. 2 is elevation cross-sectional view when locking for the utility model.
Elevation cross-sectional view when Fig. 3 is unlatching for the utility model.
Fig. 4 is the A-A sectional drawing of Fig. 2.
See also shown in Figure 1ly, the utility model includes members such as outer thimble 1, core 2, key 3.
Outer thimble 1 can be made into different shape, and can hold go into for core 2 with an interior circular hole 11, should be provided with several pin pearl holes 12 by outer thimble 1, can supply lower pin pearl 13, on sell pearl 14, flexible member 15 is inserted and form enclosed constructions to cover 16, and insert for alignment pin 18 with a locating hole 17 in addition, in order to restriction core 2 position rotating in fixed angle.
Core 2 is to hold outside in the thimble 1, and insert for alignment pin 18 with groove 21, rotate in fixed angle in order to restriction core 2, this core 2 is designed to various difformities, being provided with the mast 31 that matches for key 3 inserts, this core 2 is provided with several pin pearl holes 23 in addition, 12 corresponding the meeting of pin pearl hole of this pin pearl hole 23 and outer thimble 1, and communicate with its interior keyhole 22, make the lower pin pearl 13 of inserting thimble 1 outside or go up pin pearl 14 and can fall into, make the mast 31 of the key 3 that is inserted in keyhole 22 can promote lower pin pearl 13 risings, core 2 is provided with and protrudes the drive piece 24 of thimble 1 outside, can be in order to play the switching function of lockset.
Key 3 is provided with the mast 31 that is consistent number and can becomes to coincide and insert with core 2 keyholes 22, the shape of this mast 31 and keyhole 22, except that shape as shown in Figure 1, also can be designed to the various wings or flat that have ... Deng shape, mast 31 is provided with the groove 32 that matches with core 2 pin pearl holes 23, this groove 32 can be made into the different depths, with so that lower pin pearl 13 stops at various height, the defiber of upper and lower pin pearl 14,13 and the defiber of core 2 and outer thimble 1 is nibbled in pairs.
See also shown in Figure 2, it is the situation of core 2 of the present utility model when combining with outer thimble 1, this moment, the key 3 of correct shape was not inserted into, therefore, the defiber of upper and lower pin pearl 14,13 is to stagger mutually with the defiber of outer thimble 1 and core 2, so, on the part pin pearl 14 form jams core 2 with outside the defiber place of thimble 1, make the core 2 one-tenth can't rotation status.
See also shown in Figure 3, when the key 3 of correct shape is inserted in core 2, each groove 32 of key 3 rises lower pin pearl 13, therefore, the defiber of upper and lower pin pearl 14,13 can be nibbled state (as shown in Figure 4) in pairs with the defiber of core 2 and outer thimble 1, so, core 2 can be rotated, and can reach the effect of revolving plug 2.
