The coded lock comprises a coded disc 1, coded disc zero scales 2, a knob 3, knob protrusions 4, knob zero scales 5, a lock body 6, support legs 7, a rotating shaft 8, a lock cover 9, a pressing plate 10, limiting protrusions 11, a pit 12, knob screw holes 13, steel balls 14, a spring 15, a shaft hole 16, a groove 17, a magnet 18, a limiting groove 19, a middle coded ring 20, an upper coded ring 21, an F-shaped clamping hook 22, a jackscrew 23, a screw hole 24 and a C-shaped ring inner side opening 25.

In figure 1, the invention is formed by coaxially stacking a lock cover 9, a lock body 6, a knob 3 and a code wheel 1 from top to bottom in sequence from appearance

16 scales are uniformly distributed on the circumference of the code disc 1, and one of the scales is used as a zero scale 2 of the code disc. Knob 3 outside circumference is evenly distributed knob is protruding 4, makes things convenient for the hand to twist the rotation. One of the knob protrusions 4 is provided with a knob zero scale 5.

Two support legs 7 are arranged on two sides of the lock body 6 and fixed with the coded disc 1 through screws.

The lock cover 9 is inserted into the top opening of the lock body 6, one side of the lock cover 9 is rotatably connected with one leg 7 of the lock body 6 through the rotating shaft 8, and the other side is provided with a limit protrusion 11 which can be inserted into a limit pit 19 on the other leg 7 of the lock body 6. A pressing plate 10 is further arranged on one side, close to the rotating shaft 8, of the locking cover 9, and the cover can be conveniently pressed by fingers.

Fig. 2 is a perspective view of the code wheel 1. The middle of the code wheel 1 is provided with a circular lock hole for installing a lockset. A circle of pits 12 are uniformly distributed on the circumference of the outer ring of the lock hole, the number of the pits is 16, and the number of the pits corresponds to the scale number of the code disc 1.

Fig. 3 is a perspective view of the

knob

3, and 16 blind holes 13 are uniformly distributed on the circumference of one side surface of the knob 3, and the positions of the blind holes correspond to the pit 12 arrays on the code disc 1 one by one.

In fig. 4, a knob screw hole 13 is formed on the top surface of the knob 3. 16 blind holes are uniformly distributed on the circumference of the bottom of the knob 3, and the positions of the blind holes correspond to the pit 12 array on the coded disc 1. Each blind hole is provided with a spring 15 and a steel ball 14, the spring 15 presses the steel ball 14 downwards, and when the blind hole rotates to a position opposite to the concave pit 12, the steel ball 14 is pressed into the concave pit 12. When the knob 3 is rotated, every time the knob is rotated by one scale, the click sound generated when the steel ball 14 is pressed into the pit 12 can be felt, the counting is convenient, and the obvious setback feeling can be felt in hand feeling.

The lock body 6 of fig. 5 shows that one leg 7 has a shaft opening 16 for receiving the spindle 8. A magnet 18 is arranged in a positioning recess 19 in the other leg 7. It can attract the locking closure 9 that stainless iron made, prevents to uncap the back, and locking closure 9 rocks. The positioning groove 19 can be matched with the limiting protrusion 11 on the lock cover 9 to limit the lock cover 9 from being pressed into the lock body 6. The inside of the lock body 6 is provided with two turn recesses 17 for the insertion of a middle code ring 20 and an upper code ring 21.

Referring first to fig. 7, the bottom of the locking cover 9 has two F-shaped hooks 22 for locking the locking cover 9.

Referring again to fig. 8 and 9, the middle code ring 20 and the upper code ring 21 are c-shaped sheets with screw holes 24 equally spaced. The knob screw hole 13 on the top surface of the knob 3 can be arbitrarily provided with a jackscrew 23, the upper surface and the lower surface of the middle code ring 20 can be respectively and arbitrarily provided with a jackscrew 23, and the lower surface of the upper code ring 21 can be provided with a jackscrew 23. As shown in fig. 6. The projecting portion of the jack screw 23 becomes a contact point.

When the dial zero scale calibration device is used, the knob 3 is firstly rotated, and the knob zero scale 5 of the knob 3 is aligned with the dial zero scale 2. And then clockwise rotating for two circles to align the two zero scales again, and finishing the initialization. Rotate clockwise earlier, jackscrew 23 on the knob 3 drives jackscrew 23 of well password ring 20 lower part, jackscrew 23 at well password ring 20 top drives jackscrew 23 of password ring 21 lower part, consequently knob 3 and well password ring 20, go up password ring 21 and rotate clockwise simultaneously, the opening that rotates last password ring 21 reaches the position of pivot 8, then anticlockwise rotation knob 3, the opening that reaches well password ring 20 rotates the position of pivot 8, at this moment two f type pothooks 22 all are located the opening of two password rings and the inboard opening 25's of C type ring position, press the clamp plate 10 on the locking closure 9 this moment, the locking closure just can be opened. If not in place, the two F-shaped hooks 22 at the bottom of the locking cover 9 can block the two code rings, so that the locking cover 9 can not be opened.

The lock is used as an external lock, and the lock hole of the code disc 1 is used for placing other types of locks. The locking closure through this trick lock is provided with spacing arch, and the lock body has spacing pit, prevents that the locking closure from falling into the lock body, and the pit has magnet simultaneously, prevents the unblock back, and the locking closure oneself is opened because of gravity, need just can open by pressing the clamp plate on the locking closure with the hand.

Two F-shaped hooks are additionally arranged at the bottom of the lock cover, so that the reliability is improved, malicious cracking is prevented, the security hole is blocked, and the lock cover can be opened only by simultaneously moving two c-shaped rings to an unlocking position. The common mode can not realize opening, and the security is higher.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.

Although the present disclosure has been described with reference to specific embodiments, it should be understood that the scope of the present disclosure is not limited thereto, and those skilled in the art will appreciate that various modifications and changes can be made without departing from the spirit and scope of the present disclosure.
