Abstract

The utility model relates to a cipher lock for a diary so that the diary is not optionally opened. A lock case and a lock hook of the cipher lock are respectively fixed on the split sides of a locking page of the diary. A cipher opening mechanism in the lock case comprises a lock core rod, lock keys and a top spring under each lock key. A convex lock sheet of the front part of each of the lock keys is positioned between tooth sheets of the lock core rod. The lock keys are divided into a cipher key and a non-cipher key. When the utility model is in initial position, the lock sheet of the cipher key is positioned in a tooth opening, and the lock sheet of the non-cipher key is positioned on a flat surface of the tooth opening. The lock hook is matched with one end of the lock core rod. The utility model utilizes the functions of the lock core rod to move or to be limited to move when each cipher key and each non-cipher key are in a pressing and a bouncing states so that the aim of locking is achieved without the keys. The utility model has the advantage of convenient operation.

Description

The diary coded lock

The utility model relates to a kind of coded lock, in particular can be installed on the diary, other people can't open except that its owner to make this diary, and have the coded lock of certain privacy functions.

Diary is the record carrier that people are willing to use from cover to cover some behavior of character express daily life or thought most, therefore people are unwilling, and other people have a mind to or oneself the diary of by mistake leafing through, lock body is installed on diary so, the eager needs that the lock body with privacy functions just becomes the part of the consumer group especially are installed.Existing diary lock body roughly have dial bar formula coded lock, the knob type coded lock is several, though these lock bodies have certain privacy functions, if just can find out so-called password but spend one long period, open lock body, so these coded locks do not have strict other people effect of defence.So prior art is still not really perfect.

The coded lock that goal of the invention of the present utility model is to provide a kind of diary of new structure form to use, this coded lock has reliable security performance, easy to operate, flexible, the characteristics that outward appearance is simple and direct.

Diary coded lock of the present utility model, the major technique characteristics of its overall technical architecture are that it includes and are separately fixed at lock box and the lock hook that the diary cover page is split side, the password opening mechanism is arranged in the lock box, this password opening mechanism is by lock core pole, some locking keys, item spring under each locking key is formed, be provided with some same some gear pieces along lock core pole to projection, the locking plate of each locking key is located in the tooth mouth between gear piece, make the locking key can be up and down in the longitudinal extent that the tooth mouth is limited, each locking key top is provided with to be used to slide the slideway of positioning sliding block is set, the positioning sliding block front end has the alignment pin that is used to insert between lock box and the locking key, locking key is divided into cryptographic key and non-cryptographic key, the cryptographic key locking plate that the back original state is installed is positioned at the tooth mouth of lock core pole, and non-cryptographic key locking plate is positioned on the tooth mouth plane; Lock core pole one end cooperates fixing with lock hook.

The diary coded lock that present patent application provided is to utilize a plurality of locking keys, comprise cryptographic key and non-cryptographic key, lock core pole is carried out spacing control, have only when the assembled state of cryptographic key and non-cryptographic key and the password of concrete diary are identical, it is the operation passage that the locking plate of each locking key all gets out of the way lock core pole and gear piece thereof, make lock core pole be in free-run state, just can make lock core pole break away from lock hook, open diary.Because this lock body structure is when designing for manufacturing, locking key number and cryptographic key number can be provided with arbitrarily, and when the locking key number acquired a certain degree, the combined number of its cryptographic key and non-cryptographic key will doubly increase for how much so, and its security performance is just more powerful.In addition, this diary, so just can prevent loss or forgets the sense of insecurity that is brought with being equipped with key with coded lock.

Describe the technical solution of the utility model below in conjunction with following institute in detail to accompanying drawing.

Fig. 1 is installed in user mode figure on the diary for this coded lock

Fig. 2 is the internal construction part cross-sectional schematic of this coded lock

Fig. 3 is that the A-A of Fig. 2 is to the sectional structure schematic diagram

The B-B that Fig. 4, Fig. 5, Fig. 6, Fig. 7 are respectively Fig. 2 to, D-D to, C-C to, E-E to the sectional structure schematic diagram.

As shown in Figure 1, diary of the present utility model is split side 13 places with two front covers that the lock box 9 and the lock hook 14 of coded lock is installed in diary respectively, and lock box 9 places of lock hook 14 correspondences are provided with the through hole for lock core pole one end 8 is cooperated with lock hook 14.The password opening mechanism of this coded lock is located in the lock box 9, it includes the item spring 3 of lock core pole 12, locking key 70, locking key 70 bottoms, can uniformly-spaced be provided with several gear pieces 10 along the side on the lock core pole 12, locking key 70 promptly is arranged in the tooth mouth between each gear piece 10, certainly also corresponding gear piece 10 determined locking keys 70 positions are provided with a plurality of spacer blocks 15 in the lock box 9, and locking key 70 can be up and down in the longitudinal space that gear piece 10 and lock box spacer block 15 are limited.The head end of lock core pole 12 is provided with a groove 2 and and passes shifting block 1 outside the lock box 9, be provided with the top spring 11 that makes lock core pole 12 move left and right in the groove 2, the main effect of this top spring 11 is still can get back to original position after lock core pole 12 is struck, and unlikelyly influence pressing up and down of each locking key 70, so just can be in diary opens, can cryptographic key be set back, reduce the chance that shows and lose password; The tail end 8 of lock core pole 12 is used for cooperating with the lock hook of relative cover page.The bottom of each locking key 70 is equipped with a top spring 3, locking key 70 seams location is withstood in lock box 9 upper walls, the top of each locking key 70 also is provided with the slideway 4 that positioning sliding block 7 is set for slip, the front portion of positioning sliding block 7 is provided with alignment pin 16, the effect of this alignment pin 16 be locking key 70 by under on time, alignment pin 16 can be inserted between lock box 9 and the locking key 70, lock strong 70 be moved down be fixed on this position after a section moves.In the present embodiment, locking key 70 is divided into cryptographic key and non-cryptographic key, and when upspringing reset mode, the locking plate 6 of the anterior projection of cryptographic key is arranged in the tooth mouth of lock core pole 12, and 5 of the locking plates of projection are positioned at top, tooth mouth plane before the non-cryptographic key.When locking key was pressed and inserts the location by the alignment pin 16 of positioning sliding block 7, the locking plate 6 of cryptographic key front portion moved on to the below of tooth mouth, and 5 of the locking plates of non-cryptographic key front portion enter in the tooth mouth, become " stumbling-block " of lock core pole 12 gear pieces 10.Therefore, only non-password strong be in reset mode, cryptographic key be in by down by state the time, each locking plate of locking key 70 just can not be blocked between each gear piece 10, like this lock core pole 12 just can about move freely, at this moment the shifting block 1 of stirring lock core pole 12 head ends makes lock core pole tail end 8 break away from lock hook 14, thereby open lock body, launch diary and use.After the record end, fasten the diary strip of paper used for sealing, lock core pole 12 falls into lock hook 14 again under the effect of the effect of lock hook 14 and top spring 11, and each cryptographic key is rebounded resets again places behind the state identical with non-cryptographic key.
