Abstract

The utility model relates to a safety lock which controls mechanical ciphers by keystrokes. The utility model is provided with a lock shell, a cylinder lock core and a lock tongue. The utility model is characterized in that at least one row of cipher keystrokes composed of ten keystrokes are arranged on the lock shell. A positioning plate and cipher pins are arranged in the lock shell, and the positioning plate is connected with the root of the cylinder lock core. The cipher pins are in the shape of columns, the middle lower part of each pin is provided with an annular groove, and the cipher pins are positioned at the inner end of the cipher keystroke. The lock tongue is in the shape of a plate, the axle wire of a cipher lock is perpendicular to a plate surface, circular holes to be inserted by the cipher pins are arranged on the lock tongue, and one side of each circular hole is provided with a narrow long hole to be slid in by the roots of the annular grooves of the cipher pins. The utility model has the characteristics of convenient use and reliable action, and the probability of decoding the ciphers is almost zero.

Description

Button-type mechanical password safety lock

It is essential that the utility model relates to the human lives, is a kind of safety lock of controlling mechanical cipher by button.

At present, on the safe door, generally adopt knob type mechanical cipher safety lock in the market.

The purpose of this utility model provides the mechanical cipher safety lock of another kind of structure, and its adopts button to control mechanical cipher, and button is many more, the password that is provided just the more, the probability that is decrypted is just little, the security insurance of lock is stronger.

The purpose of this utility model is to realize like this, button-type mechanical password safety lock is provided with lock housing, lock cylinder and dead bolt, lock housing is provided with at least one row by ten pieces of password keys of forming, be provided with location-plate and code pins in the lock housing, location-plate connects with the lock cylinder root, and lock cylinder will drive location-plate and move when self axis moves; Code pins is the garden cylindricality, and the middle and lower part of pin is provided with annular groove, and code pins is positioned at the inner of password key, controlled by password key; It is tabular that dead bolt is, and the axis of code pins is vertical with the plate face, and dead bolt is provided with the hole, garden of inserting for code pins, and the rightabout that moves along dead bolt in these holes, garden is provided with the long narrow hole of slipping into for code pins annular groove root.The mode that the utility model has adopted code pins to insert in the password pin-and-hole on the dead bolt reaches the purpose of pinning dead bolt, has only when the annular groove on all code pins all to move on to when aligning dead bolt, and dead bolt can move under the effect of key and lock cylinder and unblank.

Characteristics of the present utility model are: the probability that easy to use, reliable in action, password are decrypted is almost nil.

Further describe below in conjunction with drawings and Examples, Fig. 1 is a stereoscopic view of the present utility model, and Fig. 2 is the top view of Fig. 1 along the ABCD section, and Fig. 3 analyses and observe three-dimensional view for inner body of the present utility model position relation.

Embodiment: referring to accompanying drawing, be one to be provided with four rows the utility model safety lock of totally four ten pieces of password keys, password key 2, code pins 12 and connecting rod 13 all are that the rod iron Vehicle Processing is made, press key spring 3, dividing plate spring 6, rod spring 14, pellet shot from a slingshot lock 4 and lock cylinder 5 equal selection standard spares, lock housing 1, dividing plate 7, code pins seat board 8,11, backing plate 9, dead bolt 10, location-plate 15 and base plate 16 all are that steel plate is made through machine, during installation, two parts were installed in the two sides of door-plate 17 before and after lock was divided into.Narrate working condition of the present utility model below.When lock-bit, referring to Fig. 2, lock cylinder 5 has been pushed into lock-bit with dead bolt 10, and key takes off, presses annular groove on the code pins at place, presetting cipher position all not in the dead bolt plane of motion, promptly pins dead bolt, as 12 among Fig. 2 (I) and 12 (III); Unlocking action: key is inserted lock cylinder and clockwise rotate 90 °, be pulled outwardly the sub-lock core of moving, at this moment, driving location-plates 15 by connecting rod 13 moves and makes all code pins at code pins seat board 8, move in 11 near password key, rod spring 14 pushes away lock cylinder again and connecting rod resets, then, by the password that presets, press password key one by one, relevant code pins is all moved, the annular groove of each pin moves on in the dead bolt plane of motion, be rotated further 90 ° of keys, dead bolt moves unblanks, and after unblanking, the annular groove of all code pins is all in the dead bolt plane of motion, the root of code pins annular groove all slides to long narrow hole, referring to Fig. 3 position.Block action: during locking, only need rotate counterclockwise key, dead bolt just stretches out the arrival lock-bit, when rotating 90 °, spurs lock cylinder, and dead bolt is pinned in the hole, garden that the cryptographic key that makes location-plate promote to preset enters on the dead bolt.Narrate the method for presetting cipher now, safety lock of the present utility model is when dispatching from the factory, and all code pins are all along putting, as the position of 12 (II) among Fig. 2; At this moment, lock is exactly a common cylinder lock, if base plate and location-plate are pulled down, and the code pins of press the presetting cipher position 180 ° of inversions of overturning, refills location-plate and base plate, has just become the utility model safety lock with pre-value password.The password that presets can go combination to choose in 40 positions arbitrarily, hundreds of millions kinds of choosing methods can be arranged, so the probability that the utility model safety lock is decrypted is almost nil.

The also configurable electronic control part of safety lock of the present utility model as an electronic key is set, by control circuit control electromagnet, has just possessed the electronic cipher lock function to increase new function on each code pins; An electronic alarm circuit is set in control circuit, when door opener's mistake is pressed three password keys, just sends electronic alarm signal, note or the like to remind owner.

Claims (1)

1. Button-type mechanical password safety lock, be provided with lock housing 1, lock cylinder 5 and dead bolt 10, it is characterized in that: lock housing is provided with at least one row by ten pieces of password keys of forming 2, is provided with location-plate 15 and code pins 12 in the lock housing, and location-plate connects with the lock cylinder root; Code pins is the garden cylindricality, and the middle and lower part of pin is provided with annular groove, and code pins is positioned at the inner of password key; It is tabular that dead bolt is, and the axis of code pins is vertical with the plate face, and dead bolt is provided with the hole, garden of inserting for code pins, and a side in these holes, garden is provided with the long narrow hole of slipping into for code pins annular groove root.
