Abstract

The utility model discloses a lock core of an external cipher type mechanical cipher lock, which comprises a lock core and a key which is matched with the lock core to use, wherein the lock core is composed of a lock core sleeve and a rotating shaft which is assembled inside the lock core sleeve, and corresponding multi-line and multi-row marble holes are arranged on the rotating shaft and the lock core sleeve. Marbles and springs which are assembled according to ciphers are arranged inside the marble holes. Multi-row of cipher discs for cipher use are arranged on the key. Closed holes with different depths and letters are arranged on the cipher discs. The lock can be unlocked by rotating the cipher discs on the key and aligning ciphers to insert into the lock core. The lock core of an external cipher type mechanical cipher lock has the advantages of low mutual unlocking rate and great antitheft performance.

Description

Password external mechanical cipher lock pin and key

Technical field

The utility model relates to a kind of cipher lock, specifically relates to a kind of external coded lock mechanical lock and key.

Background technology

At present, the cipher lock core that people use mainly comprises lock core cover, rotating shaft, locking plate and spacer, in the time of opening coded lock, and the password position that locking plate is positioned at set in advance by rotating shaft.There is following shortcoming in this common password lock pin: general lock core adopts spring, pellet shot from a slingshot that the form in hole is determined whether locking plate arrives the position that sets in advance, when falling in the hole, can feel obviously pellet shot from a slingshot that resistance can increase, and perhaps can send unusual sound.Therefore, the robber is often arranged when the Rotary puzzle lock knob, by feeling resistance or listen carefully sound coded lock is opened that real is dangerous; For improving the safety of coded lock, people have proposed the password that many new technical schemes change coded lock, but all there is complex structure in they, and the characteristics that cost is higher generally are suitable for safety factor than higher place.

Summary of the invention

The purpose of this utility model provides a kind of mutual opening rate low external cipher mechanical lock core and key, can't open coded lock under the situation of the password that can not find key.

The utility model is achieved through the following technical solutions:

A kind of password external mechanical cipher lock pin, it comprises the lock core cover and is assemblied in the interior rotating shaft of lock core cover, in lock core cover, rotating shaft, all have corresponding pellet shot from a slingshot hole, pellet shot from a slingshot, spring are arranged in the pellet shot from a slingshot hole, it is characterized in that around the axle center in rotating shaft the annular keyhole being arranged, evenly being provided with the every row of several rows in the periphery of keyhole has plurality of rows pellet shot from a slingshot hole; Lock core put also be provided with rotating shaft on the pellet shot from a slingshot and the spring of corresponding pellet shot from a slingshot hole with good grounds presetting cipher device in the pellet shot from a slingshot hole.

Described key is for inserting cylindric in the keyhole, have on the matrix outer wall identical with pellet shot from a slingshot hole row number in the lock core rotating shaft around outer wall one all grooves, the annular seal dish that can rotate in groove is housed in groove, deep mixed code hole and and the corresponding letter of code hole are arranged on the combination disk.

Its pellet shot from a slingshot hole count is provided with arbitrarily as required.

Rotating code-disc on the key during use, to good predefined password, key is being inserted in the keyhole of lock core, key can be opened by a lock.Because of the pellet shot from a slingshot hole on the lock core is the stack of multirow multilayer, so at the bottom of the mutual opening rate utmost point.And simple in structure, be easy to make.

Description of drawings

Be described in further detail the utility model below in conjunction with drawings and Examples.

Fig. 1 is lock core structure figure;

Fig. 2 is Figure 1A-A sectional drawing;

Fig. 3 is Key structure figure;

Fig. 4 is the left pseudosection of Fig. 3;

Fig. 5 is the vertical view of Fig. 3.

Among the figure: 1, rotating shaft, 2, the lock core cover, 3, pellet shot from a slingshot, 4, spring, 5, the pellet shot from a slingshot hole, (5-1) pellet shot from a slingshot hole, 6, keyhole, 7, the key matrix, 8, combination disk, 9, the shank of the key, 10, butterfly, 11,12, baffle plate groove, 13, code hole.

The specific embodiment

As shown in Figure 1 and Figure 2, it in the lock core cover (2) rotating shaft (1), have annular keyhole (6) in the rotating shaft (1), 8 row are arranged on the covering of the fan outside keyhole (6), every row 8 row pellet shot from a slingshot holes (5), (5-1), the spring of with good grounds preset password device (4), pellet shot from a slingshot (3) also are provided with baffle plate groove (11), (12) on keyhole (6) in the pellet shot from a slingshot hole.

As Fig. 3, Fig. 4, shown in Figure 5, key matrix (7) is cylindric, and its size is advisable inserting in the keyhole smoothly.What upper and lower settings was arranged on matrix (7) outer wall arranges grooves with lock core marble hole corresponding 8, the annular combination disk (8) that an energy rotates in groove respectively is housed in each groove, each combination disk is provided with deep mixed code hole and letter, in matrix one side the butterfly (10) that can insert in baffle plate groove (11), (12) is arranged.

Because of above-mentioned lock core has 8 * 8=64 pellet shot from a slingshot hole, therefore the password number that can be provided with is 8 ⁸Individual, make the mutual opening rate of coded lock extremely low like this.The number in its pellet shot from a slingshot hole can require to be provided with according to difference.

Using method is: 8 seal discs on the key, to good pre-set password, insert interior hand-held handle (9) key of keyhole (6) with key and can open coded lock.Since to password on the key, overcome the shortcoming of original mechanical lock, the stranger at no key, do not have password or have under the keyless state of password and can't open lock.

Claims
