Embodiment 1

[0061] 1. Set the password to A50, and fix the three password dials to the positions where the grooves of the password dials are facing the password slots A, 5, and 0 respectively.

[0062] 2. Turn the handle to drive the connecting rod to rotate. When you see the first password turntable rotate to the position of password groove A at the display window of the password cover, the reset shrapnel of the movable head passes through the groove of the password turntable; the horizontal shrapnel clamps the movable head The first inclined groove of ;

[0063] 3. Continue to turn the handle to drive the connecting rod to rotate. At the display window of the cipher cover, you can see that the second cipher turntable rotates to the position of the cipher slot 5, then the reset shrapnel of the movable head passes through the groove of the cipher turntable; the horizontal shrapnel clamps and moves the second beveled groove of the head;

[0064] 4. Continue to turn the handle to drive the...

Embodiment 2

[0068] 1. Set the password to A50, and fix the three password dials to the positions where the grooves of the password dials are facing the password slots A, 5, and 0 respectively.

[0069] 2. Turn the handle to drive the connecting rod to rotate. When you see the first password turntable rotate to the position of password groove A at the display window of the password cover, the reset shrapnel of the movable head passes through the groove of the password turntable; the horizontal shrapnel clamps the movable head The first inclined groove of ;

[0070] 3. Continue to turn the handle to drive the connecting rod to rotate. When you see the first combination dial rotated to the position of combination groove B at the display window of the combination cover, the reset shrapnel of the movable head does not pass through the groove of the combination turntable and is blocked by the combination turntable. Thereby tilting, so that the horizontal shrapnel stuck in the first inclined gro...

Embodiment 3

[0074] 1. Set the password to A50, and fix the three password dials to the positions where the grooves of the password dials are facing the password slots A, 5, and 0 respectively;

[0075] 2. People who don't know the password try to guess the password by eavesdropping on the rotation sound of the mechanical structure inside the lock;

[0076] 3. Turn the handle to drive the connecting rod to rotate. You can see the first password turntable rotate to the password slot 5 position at the display window of the password case. At the same time, you can hear the rolling sound of the metal ball in the safety box. It is impossible to confirm whether the reset shrapnel has passed. The groove of the combination wheel.

[0077] It should be noted that, the above embodiments all use the password as three digits to illustrate the structural principles, and the above embodiments can also be applied to situations where the password digits are two digits, four digits, five digits or more. C...

Abstract

The invention provides a letter and number mechanical coded lock. The letter and number mechanical coded lock sequentially comprises a handle, a code confirming part, a spring bolt and a connecting rod penetrating through the handle and the code confirming part. An interval exists between one end of the connecting rod and the spring bolt. At least two parallel code rotary discs are arranged in the code confirming part, through holes through which the connecting rod penetrates are formed in the centers of the code rotary discs, and grooves are formed in the edges of the through holes. A plurality of code grooves are formed in the peripheral edges of the code rotary discs. A connecting rod sliding groove is connected with a movable head protruding from the connecting rod, and horizontal elastic pieces of a movable part in the movable head are inserted into lower positions of inclined surfaces of inclined surface grooves of inclined surface groove pieces. A restoration elastic piece clamped between the two inclined surface groove pieces enables the horizontal elastic pieces to break away from the inclined surface grooves when turning upwards. The safety performance of the coded lock is very outstanding, when a code is not correct, the code rotary discs touch the restoration elastic piece, and the restoration elastic piece lifts up the horizontal elastic pieces so that the inclined surface groove pieces can break away from the limitation of the horizontal elastic pieces and return to the original positions. A metal round ball in a safe box makes sound, and the internal action sound is prevented from leaking outwards.

Description

technical field [0001] The present invention relates to the technical field of mechanical locks, in particular to an alphanumeric mechanical combination lock. Background technique [0002] Chinese patent CN201210161791.7 provides a mechanical combination lock. The lock includes an opening mechanism, a password input mechanism and several password units, and the password unit includes a password wheel, a driving wheel for driving the password wheel, a lock pin connected with the opening mechanism, and a matching lock for preventing the rotation of the driving wheel. The stop pin and the stop groove, the lock pin and the combination wheel are provided with the matching combination pin and the combination groove, and the moment when the stop pin enters the stop groove in the unlocking process is earlier than the time when the combination pin enters the combination groove. This technology can prevent the mechanical comparison method from unlocking, and will not cause the phenom...
