Description

The locking plate of coded lock

The utility model relates to the locking plate of a kind of accessory of mechanical code lock, particularly coded lock.

Mechanical code lock is widely used in places such as strongbox or safety cabinet at present owing to have easy to use, pick-proof good effectiveness.But mechanical code lock need often become sign indicating number, and requires the size of key of lock big, just can prevent technical unlocking, improves its confidentiality and safety.The change code operations of coded lock is generally realized by locking plate.Specifically, several screwed holes are set on locking plate exactly, adopt way to become sign indicating number the displacement of the screw on the locking plate.Because the area of locking plate is limited, only can get out 6 to 15 screwed holes, so the size of key of conventional combination lock is little, its confidentiality and poor stability.

The purpose of this utility model is at the present existing the problems referred to above of coded lock, and a kind of locking plate of novel structure is provided, and makes to use the coded lock of this locking plate to have the advantages that size of key is big, security performance is good.

The purpose of this utility model is to adopt following technical proposal to realize: the locking plate of this coded lock is made up of a code converter chip that is close together mutually and a change sign indicating number blind.On the excircle of code converter chip open slot is arranged, one group of aperture that is arranged on the same circumference is arranged in the code converter chip.Becoming has a plush copper of outwards protruding on the sign indicating number blind, also be provided with elbow in addition, and elbow is inserted in the aperture of code converter chip.Next coded lock of ordinary circumstance is provided with 2 to 4 locking plates.Rotate dwang, can directly drive one of them locking plate and rotate, and can drive remaining locking plate and rotate by the plush copper of locking plate.When rotating dwang when making open slot on each locking plate all be in same position, could open coded lock.For this locking plate, only need the aperture dial-out of elbow from code converter chip that becomes on the sign indicating number blind inserted another aperture, the plush copper position that becomes on the sign indicating number blind just changes, thereby causes the variation of coded lock password.Because the aperture on the code converter chip can be a lot, so the size of key of coded lock improved greatly, and its security performance improves.

The coded lock locking plate that the utility model provides is compared with common locking plate, has following advantage:

1, this locking plate is to set up to become the sign indicating number blind on the basis of code converter chip, and the change in location that is inserted on the code converter chip by change sign indicating number blind becomes sign indicating number.Therefore, except become the sign indicating number amount big, the operation that becomes sign indicating number is also convenient and practical.

2, this locking plate and common locking plate are very nearly the same at aspects such as size dimension and materials, and cost changes little, and do not change other structures of coded lock, and historical facts or anecdotes is executed easily, and high economic benefit and social benefit are arranged.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the half sectional view of coded lock tapered end part.

Fig. 2 is the schematic diagram of the locking plate that provides of the utility model.

Fig. 3 is the sectional view of Fig. 2 along A-A.

Fig. 4 is the schematic diagram that becomes the sign indicating number blind.

Fig. 5 is the sectional view of Fig. 4 along B-B.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, coded lock tapered end part mainly comprises letter disk (1), chassis (2), dwang (3), locking plate (5), latch (4) etc. in embodiment.Locking plate (5) is socketed on the dwang (3), and dwang (3) links to each other with letter disk (1).Locking plate (5) has four groups, and wherein the most inboard one group is rotating plate (8), adopts common locking plate, three groups of middle locking plates (5) that adopt the utility model to provide.Rotating plate (8) directly links to each other with dwang (3) by latch (4).Therefore, rotate letter disk (1), can directly drive rotating plate (8) by dwang (3) and rotate together.Remaining three groups of locking plate (5) all is could rotate under the drive of rotating plate (8).

As shown in Figures 2 and 3, the locking plate that present embodiment provided is by a code converter chip (6) be close to two of code converter chip (6) both sides and become sign indicating number blinds (7) and formed.Have two groups to be arranged in two apertures (62) on the circumference in the code converter chip (6), its both sides become elbow (72) on sign indicating number blinds (7) and are inserted in two respectively not in the aperture on same circumference (62).

As shown in Figure 4 and Figure 5, become the plush copper (71) that outside protrusion is arranged on the sign indicating number blind (7).Rotating plate (8) is stirred with its sharp adjacent locking plate (5) by screw (81) and is gone up the plush copper (71) that becomes sign indicating number blind (7), drives locking plate (5) and rotates together.And above-mentioned locking plate (5) drives next locking plate (5) rotation by the plush copper (71) that its opposite side becomes on the sign indicating number blind (7).Like this, as long as rotate letter disk (1), just can regulate the position of all locking plates (5).Open slot (61) is arranged on the excircle of code converter chip (6).When rotating letter disk (1), make open slot (61) on all code converter chips (6) when being in same position, could open coded lock.

In the present embodiment, the quantity inner ring of aperture (62) is 20 in the code converter chip (6), and the outer ring is 28, so each locking plate just has 20 * 28 kinds of variations, has substantially exceeded the variation of about 10 kinds of common locking plates.The locking plate (5) that adopts three groups of the utility model to provide, the size of key of coded lock will surpass 108 times, is much higher than the size of key of conventional combination lock.

Claims (2)

1, a kind of locking plate of coded lock, formed by a code converter chip that is close together mutually (6) and a change sign indicating number blind (7), open slot (61) is arranged on the excircle of code converter chip (6), become a plush copper (71) of outwards protruding is arranged on the sign indicating number blind (7), it is characterized in that the aperture (62) that has one group to be arranged on the same circumference in the described code converter chip (6), also be provided with elbow (72) on the change sign indicating number blind (7), elbow (72) is inserted in the aperture (62) of code converter chip (6).

2, the locking plate of coded lock according to claim 1, it is characterized in that this locking plate (5) is by a code converter chip (6) be close to two of code converter chip (6) both sides and become sign indicating number blinds (7) and formed, have two groups to be arranged in two apertures (62) on the circumference in the code converter chip (6), its both sides become elbow (72) on sign indicating number blinds (7) and are inserted in two respectively not in the aperture on same circumference (62).
