Abstract

The utility model relates to a theftproof cipher linked tablet of the cipher lock, which comprises a locking bolt chute (1) and a poke block (2). The utility model is characterized in that three or more shallow slots (3) equal width with the locking bolt chute are arranged along the circumference, the more number of the gaps is the better, the distance between the two gaps approximately equaling the width of the chute is the best. Using the utility model is capable of preventing the thief from unlocking the lock by technical decryption method and the safety of the cipher lock is improved.

Description

The anti-theft cipher connection sheet of coded lock

The utility model relates to a kind of part that is used for the coded lock of safety cabinet, file cabinet etc., more particularly, is a kind of anti-theft cipher connection sheet of coded lock.

The lockset that common safety cabinet, file cabinet, file cabinet, savings counter etc. use, be but that cylinder lock with common combination lock and control lock bolt slideway combines because simple in structure, be easy to make, price makes suitable, therefore, this coded lock has vast market.As everyone knows, the unlatching of coded lock, only in the runner position correspondence of several passwords connection sheets together the time, locking bolt inserts, and coded lock just can be opened.According to this basic principle, people can the rotational password knob, and such feel finds the aperture position (i.e. first number) on the connection sheet, reverses then and continues to look for aperture position (i.e. second number) on second sheet, can find whole numbers with this way, lock is opened.This common coded lock owing to use simple password connection method, is taked the deciphering of feel way easily, therefore, the coded lock and the non insurance of this common class safety cabinet, safety is relatively poor.

The purpose of this utility model is in order to remedy the deficiency of conventional combination lock, a kind of anti-theft cipher connection sheet of coded lock to be provided, use it the person of avoiding theft to take technical deciphering way to unblank, improving the safety of coded lock.

To achieve these goals, the utility model has adopted following technical proposals: including on the ordinary password connection sheet of locking bolt chute and shifting block, offer three small gaps at least along its circumference; This small gap equates that with the width of locking bolt chute the degree of depth is more shallow; This and the wide shallow slot of locking bolt chute are along its circumference gather (that is: the interval between two small gaps be approximately equal to chute width).

Owing on the circumference of password connection sheet, offered and the wide shallow slot of chute opening, when using feel to seek the locking bolt chute, very easily produce illusion, as being provided with many traps, avoided possibility, thereby guaranteed the safety of coded lock with the feel skilled unlocking.

The technical solution of the utility model can be passed through embodiment, further is illustrated in conjunction with the accompanying drawings.

Fig. 1 is the structural representation of active anti-theft cipher connection sheet;

Fig. 2, the 3rd, the structural representation of driven anti-theft cipher connection sheet.

As shown in Figure 1, 2, 3, a kind of anti-theft cipher of coded lock connection sheet comprises locking bolt chute 1, shifting block 2, offers the small gap 3 wide with the locking bolt chute on its circumference, and the depth ratio chute 1 of small gap 3 is shallow.The quantity of small gap 3 can evenly distribute according to the diameter of connection sheet, and the small gap 3 of present embodiment is evenly to gather totally 11.

Claims

1, a kind of anti-theft cipher of coded lock connection sheet comprises: locking bolt chute (1) and shifting block (2), it is characterized in that described password connection sheet, and offer three small gaps (3) at least along its circumference.

2, according to the described anti-theft cipher connection of claim 1 sheet, it is characterized in that described small gap (3) is and the wide shallow slot of locking bolt chute.

3, according to claim 1,2 described anti-theft cipher connection sheets, it is characterized in that the interval between the described small gap (3) is approximately equal to the width of chute.
