Description

A method of coding by mechanical means

technical field

The present invention is a method for compiling passwords in a mechanical way, which is mainly used in combination locks, and can also be used in places where mechanical passwords are required for certain password control, such as password switches.

Background technique

Existing use of mechanical means to compose codes is mainly used in combination locks. There are dial-type combination locks widely used in safes, and there are also many button-type mechanical combination locks. Dial-type combination locks are only used in safes because of inconvenient use. This button-type mechanical combination lock has been unable to be popularized and used on a large scale because of the inconvenience of changing the code, or because the password is easy to crack, or because of various defects such as manufacturing difficulties. Not going out with the key every day is not only troublesome, but also often leads to the phenomenon of not being able to enter the house because of forgetting or losing the key. The present invention is based on this design and is mainly used for the method of mechanically compiling codes for push-button mechanical combination locks, which can effectively Solve the defects of various mechanical combination locks at present.

Contents of the invention

The present invention is a method for compiling passwords in a mechanical way. There is a button push rod that can move up and down under the button. A translation piece that moves left and right; a certain number of guide pieces that can change the direction of the guide slope are pivoted on the wheel or the translation piece. When the key is pressed and pressed, the push rod and the push piece are forced to move downward, and the push piece touches the The slope of the guide will slide to one side, and then push the runner to rotate a certain angle or the translation piece to move a certain distance, so that the next guide is just facing the push rod of the button. After the force is removed from the button, the button, push rod and push member Under the action of the spring, it rebounds upwards to the initial position, and at the same time, the pusher returns to the vertical position under the action of the spring or gravity, and completes the action of inputting a password. If the wheels are arranged in a straight line, the wheels are all installed on the same shaft and synchronized. Rotation, if the runners are arranged vertically and horizontally, the runners are linked through racks or gears or synchronous belts, so that all the runners will rotate at the same angle at the same time, the translation part moves as a whole, and the corresponding guide under a certain button The inclined plane is to make the rotating wheel or the translation piece move towards the direction of unlocking the password. This button is called a coded button, otherwise it is called an uncoded button. Before entering the password each time, there is only one coded button, and the rest are uncoded buttons. The inclined plane of the guide piece under the key with code is to make the wheel or the translation piece move in the direction of unlocking the code, and the guide piece under the key without code is to make the wheel or the translation piece move in the opposite direction. When all the passwords are entered continuously and correctly After finishing, the rotating wheel or the translation piece reaches the limit position of unlocking the password, touch the corresponding switch to unlock the function of the password, on the contrary, if the button without code is pressed several times, the turning wheel or translation piece reaches the opposite limit position, and cannot be unlocked. Password, but when these two situations reach the limit, the guides under all the buttons are set to make the rotating wheel or translation piece move in the return direction, so as to avoid the rotation wheel or translation piece moving in one direction all the time, so by setting Different passwords can be set by setting the different directions of the slope of the guide, and changing the password only needs to change the direction of the slope of the guide.

When pressing the button, if the coded button and the uncoded button are pressed at the same time, the rotating wheel or the translation member will be forced in both directions at the same time, making it unable to move, so that it can be judged that one of the pressed buttons is a coded button. The correct password can be judged dozens of times like this. In order to solve this problem, the present invention sets up a button interference mechanism to ensure that only one button can be pressed at a time. The specific implementation method is as follows:

When the buttons are laid out in a straight line, a single layer of interference parts is used, and the push rod is controlled from two directions by the interference part. When the push rod moves downward, the two interference parts that control it are pushed outward by the wedge-shaped structure of the push rod. Open, all other interfering parts are forced to translate, thereby blocking all other key push rods from moving downward.

When the keys are laid out vertically and horizontally, a double-layer interference piece is used, in which a raised structure is inserted into the space of the other layer of interference piece and corresponds to the corresponding gap of the other layer of interference piece. The push rod of the button is controlled by four Interfering piece control, when the button push rod moves downward, the four interference pieces controlling it are squeezed out by the wedge-shaped structure of the button push rod, causing all the interference parts on the same vertical and horizontal lines as the button push rod to translate, Thereby block all key push rods that are on the same vertical line and horizontal line as this key push rod to move downwards, meanwhile, for the key push rods that are not on the vertical line and horizontal line of this key push rod, control the protrusions on their interference parts The structure no longer corresponds to the gap of another layer of interference parts, so the interference parts controlling these push rods can no longer be squeezed away, thereby preventing the downward movement of these push rods, thus ensuring that only one button can be pressed at a time go down.

Detailed ways

The present invention is not limited by the following examples, and the specific implementation method can be determined according to the technical scheme and the actual situation. The following uses the 3×4 button layout as an example to illustrate the specific application.

There is a button push rod 2 that can move up and down under the button 1, and a pusher 3 that can swing left and right is pivotally connected to the lower end of the button push rod 2. A rotatable runner 5 is arranged below the pusher 3; The guide 4 that can change the direction of the guide slope, when the button 1 is pressed down, the push rod 2 and the pusher 3 move downward under the force, and the pusher 3 will slide to one side when it touches the slope of the guide 4, Then push the runner 5 to rotate at a certain angle. The runner 5 is linked by the rack 12, so all the runners 5 will rotate at the same angle at the same time, so that the next guide 4 is just facing the button push rod 2. Remove the button 1 and receive it. After pressing, the button 1, the button push rod 2 and the pusher 3 rebound upwards to the initial position under the action of the spring 7, and at the same time the pusher 3 returns to the vertical position under the action of the spring 6, and the action of inputting a password is completed. Before inputting the password, there is only one coded button, and the rest are uncoded buttons. When all the passwords are continuously and correctly entered, the wheel 5 reaches the limit position for unlocking the password, and the rack 12 touches the corresponding switch to unlock the password. , if the button without code is pressed many times, the runner 5 will reach the opposite limit position, and the password cannot be unlocked, but when these two situations reach the limit, the guide 4 under all the buttons is set to make the runner 5 return to the direction The moving state is to avoid the runner 5 from rotating in one direction all the time, so that by setting the different directions of the slopes of the guide 4, different passwords can be set, and the modification of the password only needs to change the direction of the slope of the guide 4.

In this example, a double-layer interference mechanism is set up to ensure that only one button can be pressed at a time. Specifically, the raised structures on the interference parts 10 and 11 correspond to the gaps on the interference parts 8 and 9, and the buttons The push rod 2 is controlled by the four interference parts 8, 9, 10, and 11. When the push rod 2 moves downward, the four interference parts that control it are controlled by the wedge-shaped structure of the push rod 2. Squeeze outward, causing translation of all interfering parts on the same vertical and horizontal lines as the push rod 2, thereby blocking the downward movement of all push rods 2 on the same vertical and horizontal lines as the push rod 2, Simultaneously, for the key push rods 2 that are not on the vertical and horizontal lines of the key push rod 2, the protrusion structures on their interference parts 10 and interference parts 11 are no longer corresponding to the gaps on the interference parts 8 and 9. , so the interference parts controlling these push rods 2 can no longer be squeezed away, thereby blocking the downward movement of these push rods, so that it can be ensured that only one push rod 1 can be pressed each time.

In this example, there are 9 guides 4 under each button 1, of which 2 guides 4 are for controlling the wheel 5 and can only rotate back and forth, and the remaining 7 guides 4 are password-set, so this example can set 7 Bit password, the number of passwords is 12 to the 7th power of 35.83 million in total, and when the runner 5 is forward and reversed, there is no difference in the sound and power of the buttons, so the password of the present invention cannot be deciphered at all.
