Problems solved by technology

However, the key and lock of this structure require the groove to have a certain length and width, so the volume of the key cannot be miniaturized
When the groove is shorter, it will result in fewer bending points, that is, fewer control points, which will also increase the mutual opening rate
[0005] Therefore, existing mechanical locks have the problem of being unable to maintain a qualified mutual opening rate under the condition of miniaturization, such as door locks, car locks, cabinet locks, drawer locks, luggage locks, various padlocks, and even decorative locks (necklaces). , bracelets) etc.

Embodiment 1

[0024] A method for realizing coding of a mechanical lock and a key. The coding surface 101 of a key 1 is arranged on a plane between its two side edges, and the coding surface 101 is divided in the form of a matrix. The matrix is ​​4×4, as shown in FIG. 1 , the identification points are discretely distributed in the units in the matrix; the identification element is set on the position corresponding to the identification point in the lock, when the key 1 is inserted into the lockhole, the identification element contacts with the corresponding identification point, when the identification point contains When the identification information matches the unlocking information, the identification element moves to the unlocking position, and the restriction on each independent and separated opening and closing element matching the identification element one-to-one is released, and the lock is unlocked. The coordinate position, reading depth, shape and number of marking points on the ...

specific Embodiment 2

[0028] A kind of mechanical lock and key, its sectional view is shown in Figure 3, comprise lock body 8; Be located in lock body 8, and have the rotatable lock core 7 of key 1 groove; Inside lock core 7, be positioned at the top of key 1 groove Each pin 3 has a gap 301 to determine the unlocking position of the lock; the opening and closing element prevents the lock cylinder 7 from rotating relative to the lock body 8 in the locked position; the flat key 1 is between the edges of the key 1 There are not less than 2 rows of pits 2 distributed on the plane between them as identification points. This example is divided into 4 rows and 4 columns, as shown in Figure 1; when the key 1 is inserted into the key slot, the pins 3 are located in these pits 2 Right above the pin 3, a return spring is installed on the other end of the pin 3, and the pin 3 is pressed to be in contact with the pit 2. When the shape and depth of all pits 2 conform to each other, all the pins 3 are moved to the...

Embodiment 3

[0045] The structure is similar to that of Example 2, the difference is that in order to simplify the manufacture and implement different codes on each lock, the present invention adopts a modular scheme, divides the structure in the overview, and changes the overall structure to be composed of different standard components. Combination of independent opening and closing unit functional modules. Each opening and closing module contains pins 3 , and each opening and closing module is combined along the length direction to form a lock cylinder 7 . Through the permutation and combination of different opening and closing modules, it is easy to realize the diversity of codes of locks and keys 1 .

[0046] Lock of the present invention is not limited to above-mentioned embodiment, utilizes above-mentioned embodiment and can also produce multiple derivation, for example, can adopt the marble 3 of different cross-sectional shapes, as H shape, rectangle, Y shape to carry out coding com...

Abstract

The invention discloses a mechanical lock and a key-coding realizing method, characterized in that the coding side of the key is arranged on a panel between two edges of the key and is carved off via a matrix form, and mark points are discrete distributed in a unit of the matrix as the number of matrix row up greater than or equal to 2. The mark element is separately installed on the relative position inside the lock and contacts the relative mark as the key in the keyhole, and a starting element moves to the unlocking position and is a lifted restriction with unlocking the lock as the message identification of the mark meeting the unlocking information. The invention has a widely free degree of the mark element position with arbitrary permutation and combination in a two-dimensional plane, and avoids the common spring with lock-in-rows range changing the position of springs as the limitation, therefore the lock can get a higher change rate and wide adaptability while keeps the lock a relatively small volume so as the key.

Description

technical field [0001] The invention relates to a method for implementing coding between a lock and a key, and a lock and a key using the method, and more specifically relates to a technique for obtaining a safer lock by improving the coding method between the key and the lock. Background technique [0002] The tumbler lock is a common lock. The usual tumbler lock head locks the lock cylinder to rotate through the tumbler. Each tumbler group in the lock consists of two. When the lock is unlocked, the contact surface of the two tumblers and the lock cylinder and The contact surfaces of the lock body overlap, and the lock cylinder can rotate relative to the lock body. When locking, the contact surfaces of the two marbles do not coincide with the contact surfaces of the lock cylinder and the lock body. Due to the blocking effect of the marbles, the lock cylinder cannot rotate. The key of the tumbler lock is usually coded on the side of the key, and the jagged protrusions on the...
