Abstract

The utility model discloses a lock using a single lock core and a double bit five-group elastomer structure. The utility model is composed of a lock body, a lock core, a core sleeve, and two working bits which can form 20DGE-60DGE included angle. The elastomer structure which is lapped by an upper elastomer, a middle elastomer, and a lower elastomer can be installed in each working bit; two different keys only can realize the unlocking and locking operation of the lock in the process of unlocking operation, so that the utility model can effectively increase the number of balls of the lock core and can enlarge the combined probability; therefore, the utility model can enhance the theftproof performance, and the safety performance can also be greatly increased.

Description

The dibit cylinder lock

The utility model relates to a kind of lockset, especially relates to a kind of lockset that two working positions are arranged.

Common lockset is generally all by lock body, lock core, keyhole and corresponding with it working position, and the body hardware of being made up of last body and following body that is installed in the working position is formed, the shift fork of lockset is connected on the lock core, just can realize opening and closing with a key.Its lock core marble quantity is few, and the combination probability is little, and theftproof performance is relatively poor.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and provides that a kind of lock core marble quantity is many, combination probability is big, theftproof performance is superior lockset.

The utility model adopts the monolock core, the structure of five groups of bodies of dibit, by lock body, lock core, keyhole and corresponding with it working position, and the body structure that is installed in the working position is formed, wherein, between lock body and lock core, also be provided with the core retainer plate that is socketed on the lock core, core retainer plate links to each other with shift fork on the lockset, wherein, also be provided with lock core in keyhole match corresponding I working position and II working position, angle between I working position and the II working position is 20 °-60 °, at the I working position, all be equipped with in the II working position by last body, middle body, the body hardware that following body builds up also is provided with spring between the shell of plane on the last body and lock body.

The utility model has following advantage than prior art:

Because the utility model has adopted the structure of five groups of bodies of dibit, need could realize opening or closing with two different keys, it has not only increased the quantity of pellet shot from a slingshot, has enlarged the probability of combination greatly, has also increased the theftproof performance of lockset simultaneously greatly.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the sectional view of the utility model on the I working position;

Fig. 2 cuts open figure for the office of facing of the present utility model;

Embodiment 1: the dibit cylinder lock, adopt the structure of monolock core, five groups of bodies of dibit, be 40 ° angle with keyhole 10 coupling and corresponding I working position 3 and II working position 2,5 row's body structures are arranged in I working position 3, every row's body structure builds up from top to bottom by last body 8, middle body 7, following body 6, also is provided with spring 9 between the shell of plane on the last body 8 and lock body 5; 5 row's body structures are also arranged in II working position 2, and every row's body structure is to be formed by stacking by last body 8, middle body 7, following body 6, between the shell of plane on the last body 8 and lock body 5, also be provided with spring 9, lock core 1 is installed in the lock body 5, also be socketed with core retainer plate 4 between lock core 1 and lock body 5, the end of core retainer plate 4 links to each other with the shift fork of lockset.

One, unlock operation program:

When lock core 1 during, insert the I key in I working position 3 positions.All body 6 lifts under the effect of key down, and middle body 7 quilts body 6 down eject lock core 1.At this moment, all down bodies 6 last plane with all in the lower plane of body 7 flush with lock core 1 periphery.The last plane of middle body 6 flushes with the periphery of core retainer plate 4, in this state, just can rotate counterclockwise the I key, under the detent mechanism effect (in the lockset), lock core 1 is positioned at 2 places, II operating position and takes out the I key, insert the II key, body 6 inserts respectively in the hole corresponding in the core retainer plate 4 under all, and in all on the body 7 on plane and all lower plane of body 6 flush with core retainer plate 4 cylindricals, key, lock core 1 and core retainer plate 4 rotate simultaneously, and the shift fork that drives on the core retainer plate 4 is opened lockset.

Two, shut operation sequence:

Insert the II key, clockwise rotate lock core 1 to mat woven of fine bamboo strips II operating position 2, (body duty with unblank the same) taking-up II key, insertion I key clockwise rotates mat woven of fine bamboo strips I operating position 3 (body duty with unblank identical).Take out the I key, at this moment, pin lockset.Must at first use the I key when unblanking like this, if at first use the II key, because middle body 7 pins lock core 1, lock core 1 can't be rotated, and core retainer plate 4 is also pinned by the last body 8 of II operating position 2, so can't unblank, therefore, need two keys just can unblank, improved lock by the difficulty of pirate of the open, the security performance of lock significantly improves.

Claims (1)

1, a kind of dibit cylinder lock, by lock body (5), lock core (1), keyhole (10) and corresponding with it working position, and the body structure that is installed in the working position is formed, it is characterized in that: between lock body (5) and lock core (1), also be provided with the core retainer plate (4) that is socketed on the lock core (1), core retainer plate (4) links to each other with shift fork on the lockset, wherein, also be provided with lock core (1) in keyhole (10) be complementary I working position (3) and II working position (2) corresponding, angle between I working position (3) and the II working position (2) is 20 °-60 °, in I working position (3), all be equipped with in the II working position (2) by last body (8), middle body (7), the body hardware that following body (6) builds up also is provided with spring (9) between the shell of the last plane of last body (8) and lock body (5).
